[Q] SM-T800 losing 6%/day when idle - Galaxy Tab S Q&A, Help & Troubleshooting

Hey there, new member although I've been reading these forums for months.
I've owned an iPad for a couple of years now. I use it from time to time which requires me to charge it about once every 2 months. A couple of months ago, I bought a SM-T800 and thought the battery life was horrible. Keeping it completely idle for 24 hours still drained the battery 11%! After a while, I left it dead next to the iPad.
Hoping Lollipop would help this issue, I took the opportunity to completely wipe the tablet and restart from scratch. Each day, I attempted improvements (using BetterBatteryStats) and took notes of those changes. The best I could get is losing 6%/day while the tablet is off (that is, screen is off, not powered off).
Yes, I'm rooted. Not much is installed. According to BBS, com.google.android.gms is the worst with 1639 wakeups, but disabling Google Play Services didn't help.
Is 6%/day when idle considered normal? It amazes me that the iPad is losing about 1%/day.

I've had on CM12 and it drained 0-1% while on idle. With touchwiz (lollipop or kk) I lost 6% on idle when I woke up from bed. So my result is that touchwiz usually has more drain than CM12. A few custom roms like Ironrom or Twdetox make it drain less from what I tested. But before you go through all that, I've seen a tweak to stop wake locks from Google services. I haven't test it throughly but seems promising.

Here's the video. https://youtu.be/OU6knqCyvPI

I don't see what the problem of a small amount of battery being used if the device is on is?
It's obvious it's going to use some power, there are still things running in the background or you'd never get messages, emails, sync etc. Really the whole point of leaving it on.
Android itself is not the problem, it's more to do with Google services and apps.
If you don't want those things turn it off imo or completely remove gapps.

I use TWDetox v3.0 on my 8.4 tab s the SM-T800 version is beta at best experimental at worst at this time but I can give you my own experiences on a similar device, YMMV. On kitkat stock with my brightness turned almost all the way down and auto on, I also used greenify I would lose about 5-6% by the time I woke up. On this rom same basic settings wifi still on, greenify still on, tab set to low brightness I would lose about 1-2% over the same 8h though this os a debloated rom so a lot of samsung "highly important" apps are missing like milk and watch on and yea basically all the junk no one wants that runs at startup all the time.

I'm not saying it's a problem. The question simply comes from the fact that I'm comparing my SM-T800's 6%/day loss versus iPad3's 1%/day and wonder if it's normal or not. After all, the iPad is also syncing stuff and it's barely using any battery. If everyone tell me their SM-T800 drains 1%/day too, then I'll know there's something wrong on my side. If not, I'll live with the fact that the SM-T800 drains 6%/day.
I went on Cyanogenmod's site and apparently the SM-T800 is not officially supported. I'll need to read http://forum.xda-developers.com/gal...rom-cyanogenmod-cm-12-0-sm-t800-16gb-t3005540.

I think 6% a day is normal, the tablet is doing quite a bit even when sleeping, I have an SM-T800 10.5" with a the stock UK rom.
Is sleeping wifi scanning enabled, the T800 has that does it not.

Hi to all. I recently bought an SM-T700 and still playing around with it.
I have disabled everything you could imagine when I turn off the screen:
Wifi Off
No Wifi Scanning
No Sync
No BlueTooth
Everything is off
Anyway, I'm also loosing around 6 to 8% in 24 hrs of idle / screen off.
I also have an old S2. If I put it in flight mode, it won't even lose even 1% during all night stand by.
Is there anything I'm missing here?
I don't see why it shall lose 6% if everything is off. It's just on doing nothing!
Thanks in advance and sorry for my english!

I was worried too and that's why I came here to ask if this situation is considered normal. It apparently is, unfortunately.
It seems the stock OS is taking more juice if we're comparing it with CM (according to DUHAsianSKILLZ) which only takes 1%/day. If it's true, I fail to understand why the stock OS takes at least 6 times more than that for the same results. That can't be good and we can't blame everything on bloatware.

This is a screenshot I a few months ago. This was when I went to bed and woke up in the morning. I forget what I did but, I did do something I don't remember that would stop wakelocks. I think I did a few things in app ops. This was touchwiz Lollipop.

Thanks for your replies.
I bought this just two weeks ago and was amazed about how low was the standby battery consumption after upgrading to LL via OTA.
But suddenly (I installed a few apps) it started increasing the idle consumption.
I'm going to factory reset the tablet and turn everything off to see what happens (I have nothing important yet on it as I was just learning how to use it and hesitant about rooting ir or not, finally decided 'Not yet').
As I'm not rooted i feel there isn't much I can do about it (On my old S2 i use Greenify, Amplify, App Quarantine, Disable Services, etc.).
If somebody else have info regarding idle battery consumption on stock and non rooted I'd really appreciate it (Wifi off, location off, sync off, etc.)
Best regards
Mariano.

before I rooted and flashed cm I was only getting 2% drain overnight just by turning on airplane mode.
You could also try turning on ultra power saving mode before you sleep, I think it said it has something like 140 days battery life when I turned that mode on at full charge.

I tried it during the last 24 hours and the battery still drained 6% by sitting on my desk in ultra power saving mode. I think this mode reduces the display which drains less battery but I don't think it has any effect on the processor itself. The wakelocks still happen.
I'll try the airplane mode for the next 24 hours but I fear it won't do much.

Oh my God!!!
Airplane mode during 24 hours. Battery drain result: 0%
How can this be? I remember once trying to simply disable WiFi and it didn't change a thing. I don't understand why activating airplane mode changes anything. Could it be that with WiFi off, Android's system still tries to access stuff (creating wakelocks) but, in airplane mode, it completely halts all data related activities (halt related wakelocks)?
I'm truly astonished by this test. Thank you very much Pleske for that suggestion!
Next test: Airplane mode on with WiFi on.

Airplane mode with WiFi enabled still drained 6%.
I installed "Timed Toggles" (https://play.google.com/store/apps/details?id=uk.co.ergodicity.timedtoggles) to automatically enable Airplane mode and disable WiFi at midnight. It's still not as impressive as the iPad, but it's incredibly better than losing 11% each day.

Um...... well 3 small things.
1 Turning on wifi after you turn on airplane mode makes airplane mode pointless unless you also go around with bluetooth on all the time since on the t-800 those are the only 2 radios the tablet has.
2. Odds are you are getting attacked by the battery saving feature of the interactive governor that the galaxy tab s uses which when woken up instantly cranks the processors up to 1.9GHz to help deal with what woke it up and to be ready to be snappy and handle what ever it is that you want to do, unfortunatly if you are asleep it runs like this fpr a bit then goes back to sleep. Get enough annoying things telling your cpu "hey hey look at me... I need you look at me" and you get some drain happening. Not sure how the ipad handles waking up but it does have a far less powerful and therefore power hungry processor to wake up.
3. Greenify still works even if you are not rooted and do not have exposed, it just does not do as many things automatically for you and can not handle Samsungs very important system bloatware for you. You can still stop the apps yourself or freeze them yourself.

1. I remember trying to disable WiFi (not enabling Airplane mode) and it didn't change a thing. For some reason, activating Airplane mode does have a dramatic impact compared to just disabling WiFi. Bluetooth has never been activated.
2. iPad's CPU vs. T800.... good point. That should be a good reason why iPad's battery seems better but is it enough to justify T800's 6%/day? I wonder.
3. I do have Greenify installed and set up for a couple of apps. As for bloatware, I disabled all those I could think of.

Ipad 1 -- 1 GHz ARM Cortex-A8
Ipad 2/3 -- 1 GHz Dual Core ARM Cortex-A9 (different gpu though between the 2)
Ipad 4 -- 1.4GHz Dual Core ARM processor
Those are the regular Ipads the Ipad air 2 comes the closest to the tab s with a tri cor 1.5GHz processor
That is just the differences with the processor when you also factor in that IOS is a very regulated system of what can and can not be installed, what apps can make what system calls, and general management that makes Apple very annoying for a PC makes IOS a very fast responsive and stable OS for phones and tablets even with much less powerful hardware. It is the basis of the difference between a specialized and a general computing platform. Apple products will get better battery life on average and be more compatabile with less issues then android until (and I would hate it if it happened) Google makes one device with only slight differences for screen size or storage and that is it. Also all apps would have to come from the store and be screened far more then they currently are.
The big advantage android has is with root and custom roms our performance increases where as jailbreaking ios devices either keeps performance the same or can even degrade it.

Apple products have amazing battery life in general. Maybe except for Macbooks (non-air), which still have great battery life. Apple's phones, tablets, and MP3 players have amazing battery life compared to similar products from other brands. I don't know what they do, but there's some magic to their battery and power consumption. I'm not surprised every Samsung device I owned had lower battery life than it's contemporary Apple equivalent.
iPad Air 2 vs T800 specs relating to power consumption:
mAh: 7340 vs 7900
Cores: Tri 1.5 vs quad 1.9 + quad 1.3
RAM: 2 vs 3

[Q] [Q, DISCUSS] Xperia Play Battery Life

I have a long story with this.
First of all, let me say that two days ago, my battery life was incredible- from 2:00 PM to 9:00 PM, WiFi, 2G on browsing the internet and it went only to 64%.
I slept early that night, around 10:00 and woke up at 6:30. My battery was at 29%. I did download an application (or two) that night, the game Modern Combat 3 by Gameloft and Dragon Go! (which I just deleted.)
I'm rooted, with a R800x. Anything I can do to improve battery life? (Custom ROMS, tips, tricks, etc.)
Also, if you need any additional info (except my address and stuff ) go ahead and ask.
Also also, this is also a discussion thread. Go ahead and share your battery life with the world
techelec
Try Juice Defender. I've seen a noticeable difference in battery life.
put cola rom on . that will help to start.
secondly you can underclock the processor if your not gaming
I havent had any issues with my battery yet, this phone has the best battery life of any phone i have had in the past 2 or so years. Somethings i did to help my battery life, is when im at home, i turn GPS off, turn data over mobile network off, turn wifi on, turn auto brightness on, and the only widgets i have that require updates is my clock/weather widget. I also dont have anything but the bear minimum running in the background. (just my google and facebook sync, and maybe 1 or 2 others aside from what you cant turn off) Yesterday for example, i left my phone off the charger all night woke up was at like 94%, downloaded a few things, played on XDA for about 20 minutes then played MC3 for about 45 minutes, and Dead on Arrival for another 30 minutes, and my battery was still at 90%. I know it seems far fetched, but its a true story. I dont think i plugged my phone in until about 5 hours later and that was only to my pc to transfer movies from PC to Phone. I dont ever really charge my phone, it just gets what it gets periodically when i plug into the PC to do some work.
Battery life is very good. Running stock 2.3.4, rooted

My battery life used to be amazing. After updating firmware to the .42 version suddenly I get less than half..
Also for some crazy reason deleting some of the bloatware actually made it worse, so I put it back and it improved? Weird. Still way less than before though.
Also, I did in fact disable automatic network searching so that's not the problem.

Left my phone on for around 9 hours while sleeping, and it went from 60% to 38%. I used to get around a 1% drain or less per hour while in standby with data on, and about half a percent with it off. My battery usage has literally become more than double after leaving 2.3.3

I'm currently trying to find out if the brightness app hatcyl made drains extra battery. If not, I'm going back to 2.3.3 since the auto-brightness problem was the only reason I updated.
The phone that was made for gaming is now useless for it. I used to play games on the bus, or while in a car. Now if I do that, the battery dies right away, leaving me without a phone.
What the hell is the point of a portable gaming device if it can't be used anywhere without a power outlet?
I paid a premium price when the phone had just come out, and now it can only be used at home for games? I have both a PC and an xbox 360 for that.
I dunno what Sony Ericsson changed in the last couple updates but they turned a previously awesome device into a useless brick.
I put up with this big fatty phone cause of the gamepad.. Now I'm starting to regret not getting an Arc. I watch lots of movies and would have loved having an hdmi port. Plus with a ps3 controller the Arc can play emulator games through a TV, with tactile controls. The Play has a great gamepad, but no hdmi, so I got it with the intention of only using it on the go. Again, now unable to do so.
And before anybody says "go buy extra batteries" you're missing the point. A device shouldn't require extra batteries to carry out it's intended purpose.

So true! I'm running on stock 2.3.3 Verizon R800x. Carrying around stupid batteries isn't convenient.
I'm on Stock 2.3.3 (rooted) but the battery life still sucks. Also with JuiceDefender.

Hey XperianceIT, do you mind telling me what you have in your phone and how you stop applications from running in the background? Sorry, I'm a newbie. I actually rooted with the Easy Rooting Toolkit from DoomLoRD and I had to read for a few days before starting the process.
I'm also coming from an iPhone 4- new to Android platform (and I must say I'm glad I switched to Android)
Are there any applications I should download...?
Thanks
Coming from an iPhone (1st generation) I must say the Play's battery is a godsend.
I have a CDM8950, so I always have my Play in Airplane Mode. I usually play a good 45 minutes per ride to work, and another 45 on the way back, watch one or two episodes of anime, read manga for a good hour, and have WiFi on constantly, pulling emails from 2 accounts, and texting over Google Voice. I get a good 24 hours with still 50% left. Running usually CM7.2.0 with an underclock to 700MHz when screen off, and 1.2GHz with it on. Best battery I own, lasts longer than CDM8950, laptop, and camera combined

Haha, that's actually a pretty good idea! Use a flip phone for your daily calling needs, Xperia Play for gaming and smartphone!
Love it
I actually have this on and off... sometimes battery life is OK, sometimes it's downright horrible.
edit: I forgot to mention that my Play is underclocked at 122 Mhz when it's in sleep mode and around 700 Mhz when it's on, full 1 Ghz when I'm gaming
After all, what's the ultimate gaming phone in the world without BATTERY LIFE?
By the way, I am talking to a fellow manga/anime fan so... this is totally off topic but what do you use to view manga/anime?

The firmware has a known battery drain bug caused by network search. Go into your settings and set the network to manual selection instead of automatic.
Other things you can do is turn off data when you don't need it, and use widgets that are more efficient. If you want to leave data on all the time, you can try setting certain apps or widgets to update themselves less often.

[Q] SIII LTE Poor battery life USA AT&T

I received my Galaxy SIII on Monday and haven't been able to complete a full day with light to moderate usage. Yesterday after about 11 hours of mainly standby / light usage I had about 3% battery before I was able to charge it.
Is this normal? I'm coming from an iPhone 4 (this is my first android phone) and was quite excited about this. But if I can't make it through the day what's the point. I have noticed at times that the back of the phone can get quite warm, not hot, but definitely warm. Perhaps I have a faulty battery?
I've heard Android can be a bit notorious for poor battery life, but I didn't expect that I wouldn't be able to use it for the fear of the phone not lasting the day.
My iPhone 4 I could use it quite often throughout the day and end the day with close to 40% battery life and if needed I could last through the night well into the next day without a charge.
Will I have to carry around a spare battery / charger at all times.
Here are some screen shots from today. I've been awake and unplugged for nearly 3 hours, barely used the thing and I'm already at less than 70% with HIGH cell signal standby.

Hmm, looks like yours may be fairing better than mine based on your usage. Looks like you used it for a good 40 minutes.
When I use mine I can watch the battery percentage drop. I really hope that this is an issue with my phone and not the phone in general. I really like the phone and it's a nice change from the iPhone (little quirks here and there but still nice).
However, if the battery life is this bad (bad IMO perhaps this is actually good), then I think I'll have no choice but to return this phone - assuming I can. Otherwise I guess I'll have to drop the money for extra batteries.
I've gone as far as basically making email manual. I've turned off that stupid S-Voice thing so it won't wake up by me saying "Hi Galaxy". Guess I'll turn off WiFi and GPS (though I feel I shouldn't need to). I have battery saving mode on as well and I've dimmed the screen down to what looks like 20%...
EDIT: also, the maps that used 6% of total battery usage was me just taking a look at the widget and disabling it. Less than a minute of usage...
Your phone is not sleeping. Install better battery stats to see what is keeping it awake.

Also cell standby means you are in a low signal area which from your screenshot appears to be correct.

Unfortunately I can't do much about that since I'm at work
Do you have a recommendation for a good battery monitor? One that preferably doesn't cost money?
When it was awake I believe I had been messing around with it. I've checked it again and it hasn't been awake that often (just spurts). Looks like it's periodically syncing with my email, while I realize this will cause the battery to be drained I wouldn't expect this to be too large a deal. I would think I should be able to have my phone idle and still be able to receive emails without it causing too much of an issue. All my accounts are set-up through IMAP (minus my exchange account - which I've set-up to run manual during peak hours and check once an hour during non - peak hours) so the emails should be pushed to the device since I shouldn't be polling the servers (although it's possible I don't know too much about IMAP....).

Better battery stats is free if you search for it on XDA and from your above screenshot it is awake without the screen being on for a while. I think you have an app using up CPU processes.. poorly written apps will do this

If WiFi is enabled and I'm connected does mobile data get disabled?
I also found an App called Juice defender, is this something that is recommended to use?
I got the BetterBatterStats app installed. I'll do a full charge, then see what it has to say.
Thanks for your help.

That's what I am here for juice defender is good for longer periods for use so yes you might want to look into it. Wifi does not automatically disable mobile data I do not believe.
I also think you can load up better battery stats right now and it will tell you data

I don't know, I am pretty sure I thought the same of BBS but tried it for the hell of it last time and it was able to pull my stats from the current charge because they were just pulled from the system anyways.
Mobile data is not toggled off in the settings when wifi is on

I just got and activated my S3 on Wednesday and am having the exact same problem. I'm also on ATT and am coming from an iphone 3GS. First day I had the S3 I barely got 8 hours out of it, most of that time in standby mode and with nothing but the stock apps installed. Yesterday I cycled the battery and drained it to completely dead to where the phone wouldn't even try to turn on. I then charged it to 100% with the phone turned off. I then unplugged it to see how much battery life it would drain on standby overnight. In about 6 hours while I was asleep it went from 100% to 93%. Then I left home and between that time and now, 7.5 hours, with minimal use which included less than 20 minutes of phone calls, downloading 3 apps, syncing email a couple of times, etc.. no games, no videos, no music, no internet browsing, nothing....
Battery is now down to 24%
Screen - 1h 42m 26%
Android OS - 10m 7%
voice calls - 17m 5%
and the rest of the stuff at about 5% or less,
basically, in 7.5 hours of doing almost nothing, with power saving mode turned on and juice defender also active, my phone has gone from 93% to 24%.
Before I got the phone I read several reviews that said the battery life on these phones was supposed to be excellent. I can't imagine that this is what would be considered excellent. My iphone, which I replaced because the battery was dying, would easily last twice as long as this and that's with heavy use including games, pandora, youtube, and internet browsing.
Aside from the short battery life I'm also experiencing horrible wifi issues. On my wifi at work it will constantly disconnect and reconnect over and over. I had my iphone sitting next to the S3 and the connection was rock solid.
I contacted samsung and ATT and they did not have any suggestions or solutions but the guy from ATT did suggest taking the phone to an ATT store and they would give me another battery to try and if that didn't work I could exchange the phone.
I hate running around exchanging stuff but I'm very disappointed with this phone so far. Half the battery life of my iphone and horrible wifi connectivity isn't what I'd expect from a phone which has been touted as being significantly better than the iphone 4S and possibly even the iphone5 when that's released.
Any suggestions? I'm really trying to love this phone but so far...meh....not so much..... I love the screen, the interface is very cool, it's lighter than my iphone, but if I can't get more than a couple of hours of very light usage and no solid wifi connectivity, I don't know.... Once I get these problems ironed out I have a couple of other total newb questions about things I need to do with it but first things first...if I can't solve these problems, this phone won't work for me. Hope you guys can help! :good:
I'm glad (but not glad) to hear I'm not alone. It really is frustrating. I've been in the process of charging my phone which is taking a long time in and of itself (although I am connected to USB on my PC). It's been plugged in for 2 hours and gone up 24% eh.
I'll probably take it to the AT&T store and talk to them about it. If I can't get is solved I'll probably exchange it, but that exchange would have to be a guarantee that I'd either get the iPhone 5 when it comes out without having to pay full price, or perhaps the HTC One X, but I hear that isn't much better either. I have a friend who has the HTC One X (or the variant of it on Sprint) and he get's two days of battery life with some gaming even.
I do not want the 4S since IMO it's a worthless upgrade from the 4.
I'm located in the suburbs of Chicago so I have 4g LTE just about everywhere, granted my signal is a bit weak in my building... by a window.
If you come up with anything let me know and vice versa.
Yeah, you're definitely not alone. I've read some other posts on this and other forums of people complaining about the same thing. I have 30 days to return it so I really want to see if I can figure out how to make it work. If not, I'm going to do the same thing you're thinking of -- take it back and hopefully they'll let me go back to using my old iphone until the iphone 5 comes out, then get that one at the new contract price. Like you, I have zero interest in the iphone 4S.
I have to say, this is really frustrating and disappointing. I was expecting an "iphone killer" and instead I've wound up with a phone that with light to normal usage is pretty much dead by 3 in the afternoon. I can't work like this.
And like you've noticed, it does charge very slowly. Even through usb my iphone would charge very fast. 20 minutes in my car would give it about 15% more charge. The S3 goes up maybe 2 or 3% in the same time. I can live with this but not with the battery life or wifi problems.
btw, I'm trying another full discharge cycle tonight to see if that helps any. I really hope I can get this resolved. When I got the phone I started shopping for accessories like a car dock, screen protector/case, etc.. and was ready to order some but held off when I saw how crappy the battery life was.
No one has said this yet, but you are using a different version of SGS3 from us. You should go over to the ATT LTE boards and get help.

I am also in the Chicago area weak signal will destroy your battery so that could have a LOT to do with it. The sprint One X also is 3G only for the time being, so it doesn't have those life-sucking "4G" issues.

Almost 2 hours of Screen On, is not bearly doing nothing. It's nearly a 5" light bulb you're leaving on.
Your signal may also not be as good as on your iphone in the same areas. But both of you seem to be on par. Yes android devices don't last as long as an iphone. There's more to do and more do on an Android than an iphone. You're also in your honeymoon stage..
Did some research found this link to force hspa so it disables lte or wont connect to it. Going to try that. Not sure if this disables the antenna and you'd still get the battery drain.

No you will not experience the battery drain if you disable LTE in this way.

If I'm understanding you correctly, are you saying that the ATT S3s are different than the other S3s and are expected to get less battery life?
btw, where are the ATT LTE boards you're talking about?

Standby Battery Life?

I know there are threads regarding battery life out there, but most are all about usage and screen on time. My Note seems to be on par or at least close as far as screen on time. However, I'm just curious as to what all of you are experiencing as far as standby time. I've gone through the battery life guide and turned off most features I don't use, but the standby time still seems pretty lame. From a full charge, its been 3d 5h on battery with zero screen on time other than checking the battery stats right now, and it's down to 9%. Android OS consumed 57% and Google Play Services 33%.
I know I'm comparing Apple and Oranges here, but my 4th gen iPad I have for work hardly drains at all without use. After a week of standby, the iPad will only drop about 5-10%. I feel like this tablet should be capable of the same, and possibly will be after I root and find a good rom (also don't like to see any Apple product out-perform any android based product). Am I alone here?
Basic setup: Stock Rom (not rooted), Nova Launcher (prime), GPS off, Bluetooth off, reading mode off, multi-window off, screen mirroring off, s pen detection off, all samsung crap off (air view, etc), and others. Basically the only thing on is wifi.
I only have wifi off during standby and it drops 1-2% every 12 hours
You might have a tough time getting people to compare their standby time with yours... most people on this forum either use their tablet for work and if not are too in love with their baby to let it sit there untouched for days on end When I couldn't use mine for 12 hours, it dropped about 3% with WiFi and GPS on
Sent from my SM-P605 using Tapatalk
Yeah it is too hard to not touch it for days on end to test this. Turning off wifi while in sleep mode will help a lot. Go to the Connections tab in settings and hit the hardware menu key, then choose Advanced, and change Keep wifi on during sleep to never. That has helped me a ton. Right now mine is at 2d 7h 40m uptime with 4h screen time and it's at 32%. Even with that setting on, my iPad mini still gets better battery life. I have left it sitting for 2 days before without touching it and found it sitting at 92% battery life with wifi always on. My guess is it's something to do with the OS and iOS is just more efficient. That's why even with weaker hardware it can still outperform android tablets.
Also I'm still running a lot of the things you have turned off. You might want to also try Greenify. It has a non root working mode now, but works best in root. You can also try Wakelock Detector to see what apps are waking your cpu, so you can see what to Greenify. If you root you can also try an app to freeze apps as well like Titanium Backup and Rom Toolbox.
yeah, forgot about greenify. you have to be rooted though an need either the donation version to greenify play services(that's the battery killer) or use titanium to make it a user app to greenify with the free version. it's sad that google is the worst culprit with battery drain on all my devices.
I get 1-2% battery drop every 24hrs of standby. WiFi must be off, it not hard to just pull notification bar down and touch the wifi section off whenever you think you wont use the tablet for a while - takes like 2 seconds.

I have yet to try my battery life with wifi off, so I think that'll be next. I really don't need it connected while the screen is off, so I'll change that setting first.
I figured it might be difficult to get a good response for this question because I too have a hard time putting the thing down. Was just traveling for work and had it in my bag those 3 and noticed the battery drop. I appreciate all the suggestions and welcome any future ones. In the mean time, I'll be experimenting as well and report back if I find anything causing the drop.

Screen on time

It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Sony Xperia XA2 before depleting the battery.
Then, drop a comment if you have anything to add!
~8-10 of SOT in 2 days with auto brightness
Hello all,
auto brightness working good and very fast,
Most of time I reading in room, so no need high brightness of screen.

I think it's not the processor, it's the screen. It is very good, due to a good safety of brightness.
If needed i can make some tests, like screen time of youtube via wi-fi on max brightness, i think it will be ~6h of SOT.
I'm getting those numbers. Pretty good to me, finally I'm charging each other day.

i am too very happy with my XA2 battery life it can easily last 2 days with my mediocre to some times heavy use and if it really pushes itself i can get up to 12h SoT on wifi and around 10h with mobile network which beats my old p9l SoT 3 times.
lol, are you people not using your phones at all and just leave it with screen on?
I'm barely getting 4 h...
How? Explain to me please. Also, battery overheats up to 45-50 degrees when charging on sofa.

It differs very heavily on use most of the time i use my phone for chatting calling camera music listening and YouTube with these i get around 10hr SoT all day i do game on it some times and when i do the battery shortens this matters on how long etc if i hold a gaming session with my friends it tends to make me go for a charger in about 4hr SoT it also differs on what is enabled like BT wifi mobile network GPS etc and the screen brightness which for me is around 35% always except when I'm using the phone on the street and for heat issues i don't have them or just didn't notice it yet is it happen to you while charging? Try to use less the phone while charging or charge without case i usually don't use my phone while charging as i charge over night or it charges fairly quick to a good 60-70% battery.

Thanks for the response. So, 5-10 min in the sun, even not charging, battery just went up to 47 degrees (also one reboot).
As for the SoT, on average, I'm using the phone for voice calls, texting in Telegram, reading news from Google Now feed using Chrome and a bit of Instagram. BT is always on as I use it in my car, as for WiFi, I have it set to switch off when sleeping. I even installed Greenify, so phone goes to sleep faster. I always charge without a case. And in the car, near the windshield I have to use an A/C if it's sunny, even when not using the phone, because it overheats a lot.

No, not random reboot, thankfully, I rebooted it myself, just said it to underline the fact that it overheats a lot when starting.
I'm running the latest software, of course. Alright, will try to ask Sony Support, but I'm pretty sure, all they will say - do a factory reset.

Just don't use the stock ROM. It comes with a lot of bloat that always runs in the background and drains the battery.
On LineageOS you can adjust which apps are allowed to run at boot or stay active in the background. These settings are somewhat hidden in the privacy options of Trust.
Roughly translated from German:
Settings -> Security & Data Protection -> Trust -> (Privacy) Data Protection -> (tap the three dots) extended/additional options
In there, I've disabled background usage for a ton of apps. I don't need Facebook or Instagram starting at boot or always running in the background, for example. The only thing that always runs is Whatsapp.
With these tweaked settings, my phone lasts about 2 1/2 days with moderate usage (some browsing on the way to work, listening to music etc.)

Well in all honesty I'm not a very heavy user but I do listen ti alot of music and use to call or chat with my friends family etc and the phone is mostly in use so like to that close to 2 days there's around 8h SoT involved with minimal gaming but I mostly do that at home with charger being close either way make use of the stamina mode if needed there's performance preferred option too make sure to not exclude just the must apps from power save if you excluded any before it is a good idea to do a full charge to 100% and then wait like 10 minutes once per week (this only if you charge similar to me to put up in the morning with fast charge to 95~%) and ofc screen brightness NFC GPS etc make sure to disable all that's not needed for me GPS is on battery saving mode and NFC is by default on for some reason so don't forget to turn that off as well either way P is already confirmed early in 2019 which will bring adaptive battery that should improve the battery quite nicely

What your mentioning are really good methods to save battery specially Los is a very light firmware ? but I need to disagree abit as not everyone has the nerve to screw with custom roms etc and for that part they most likely will stay stock either way in your post I only disagree with the part where you say it's bloated yes it is that's sure but it's not even close to some like miui or emui otherwise good tips for long battery

Depends. The European ROM seems to be extremely bloated compared to other versions. But there's a dedicated thread for that.

Depends. The European ROM seems today be extremely bloated compared to other versions. But there's a dedicated thread for that.

Is the quality the same?
Yes. Full 23MP for photos and 4k 60fps video recording.
Ok so i don't know if this is from the latwst update, but my usage got significantly improved.
I still do a bit of gaming at school and watch YouTube videos(with yt using the most battery).
I can now easily get day or more of battery life, good job on that update sony?

Question Severe overnight battery drain

I've got myself a new P6P and basically since day one, every night or every other night it would lose something like 15 to 25%. This is over roughly an 8hours sleep.
Device is connected to WiFi and always on display is disabled.
Gram battery graphs look scary, like Oreo times scary.
Is anyone else experiencing anything similar, or is it just me?
Hibernation while screen off seems totally off at 27% of the time (should usually sit around 90% unless for example streaming or downloading stuff with screen off).
My previous P5 would do considerably better, with an almost flat graph in the same test conditions.
Thanks!
And the most frustrating about all this, is that in 2021 Google still can't provide us an easy way to figure out what's wrong.
Over several iterations they've promised we wouldn't have to deal with crap like this ever again (Doze, Doze on the go), but ultimately when it happens, users have no clue.
I'll have to install battery historian once more. I thought I was done with this crap.
P.s. I'm of course very interested to know what YOUR numbers look like in similar conditions. Thanks!
Hey,
I was having a similar issue on my P6Pro with high idle drain (about 1.8% to 2% per hour) using AccuBattery Pro to measure over the last week (got my device last Tuesday).
I just rooted last night so effectively did a fresh install on the November firmware. I turned off AOD, Digital Wellbeing and Lift to Wake as part of this.
I haven't really used root to prohibit anything I couldn't have done without root (yet) and last night used EXKM to track stats.
Over 7 hours I only lost 2% battery and had idle drain of 0.28% per hour which is much much better.
You've already said AOD is off but not sure about Digital Wellbeing. I'm not sure if the factory reset and setting up straight on November firmware helped the situation but might be worth a go?
I quite agree. Everytime I get a new device (have usually been from Google), I have to start off troubleshooting battery drain and installing other apps to do it.
Android 12 has light doze now, so after just a few minutes it will stop apps accessing the network, and force apps that need to get some data every few minutes or so, to all queue their requests for the next maintenance window, so this should very quickly after the screen is off, allow the phone CPU to enter deep sleep for most of the time, i.e. nothing is running in Android until the next maintanence slot.
What is likely happening is there is a wakelock stopping the deep sleep from happening, and Andriod remains running doing very little, keeping the CPU awake ticking over at 300MHz.
To test this theory install CPU Spy https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy&hl=en_GB&gl=US Have a look at the stats, has the phone entered deepsleep and what is the percentage of deep sleep? Overnight the phone really should be able to get at least 80% deep sleep as no one is using it (I've seen 95% on tablets and my Pixel 2 XL overnight).
To run a quick test, reset the stats, and let the phone sit for 30 minutes or so without being used, then go back to app (will need to use Refresh to get the latest totals) and see what percentage you get of deep sleep.
If you find the phone is going into deep sleep okay and overnight is 80% or more of deep sleep, then that isn't the cause of your battery drain, and it is likely caused by either the modem flapping or constantly trying to register with a cell tower, or perhaps Wi-Fi. So your next test is airplane mode overnight.
My overnight losses are around 5% at the moment, I'm only on Wi-Fi overnight, the mobile network is off as I get next to no signal.
Mine dropped 20% in 8hrs over night, seems a bit excessive.

I'm super paranoid about this stuff, and so since I knew that an OTA was in the pipe when I received it, I just skipped the first time setup to go straight to System Update and install the OTA
Then I factory reset, and only THEN I set it up properly with my Google account etc.
So I guess this answers your question
Digital Wellbeing is on for me tho (lift to wake is also off, as it tap to wake - although there's the bug, I think, which would still enable the screen in B/W mode when phone is lifted).
2% in 7 hours is awesome, that's what I'm aiming for, but I'm really not willing to root
I guess I will re-factory reset and maybe installing apps in batches, instead of all in one go...
EDIT: just re-read your post and you said you haven't made any of the root-enabled modifications yet, so even more call me amazed. I guess I'll also try disabling Wellbeing at this point...

It is, especially if you consider that it's 1000mAh.
A Pixel 2 XL dropping by, say, 10% (which is still much higher than what I used to get), means a consumption of 352mAh.
In terms of efficiency, a crappy P2XL performace is still thrice as efficient as what we're seeing here on the P6Pro (and ideally tech should move forward and become MORE, not less, efficient...)

Yeah,
In terms of root, I hadn't done anything with root until this morning really so there shouldn't be anything affecting my idle drain figures that you wouldn't be able to do without root.
Otherwise, try turning off all digital wellbeing features (bedtime mode, timers and focus mode) and remove permissions to digital wellbeing and then clear data. Try that for a few days and see how that has an impact.
I've noticed the same issues, I would normally have my phone switch off over and and switch on but this doesn't seem to have that option

Quite agree with you there, my Pixel 2 XL often goes 5 or 6 days without needing to be charged, although to be fair I'm working from home and it gets little use during those days and only on Wi-Fi for most of it. so not typical usage. I don't think the Pixel 6 Pro will go as long, in theory with exactly the same usage it should go for longer as larger battery and newer chips sipping less power, certainly when doing little in standby.
Too early to tell if the Pixel 6 Pro can better 5 or 6 days as I've been playing with it a lot more, but in theory it should without question, so something is seriously wrong it it can't.
As for the Pixel 2 XL, I dip into it now and again, and the one thing I'm missing on the Android 12 is not getting true black, why have they made black dark grey on all the setting pages etc? Why reduce contrast? I'd love to be in those design meetings just to see what rubbish they come up with to justify some of these changes.

IIRC full black will cause smearing while scrolling. And the display of the P2XL was, let's say it, crap.
The Pixel 2 XL display looks absolutely fine to me, and I have never seen any smearing when scrolling. When we had LCD everyone was raving about OLED having true blacks, and everyone wanting a dark mode, now in many places in the UI it looks worse then most LCD panels for contrast. So its now fashionable to have artificially lowered contrast.
Android 12 DP2: Dark theme on Pixel gets even lighter
Android 12 has tweaked dark mode again in its second developer preview to make it even lighter than the previous release.

Google, give us the option to change it back, it is suppose to be Material You so we can go back to customising again (like we once had), but it seems the only options now are washed out pastels.

Can you monitor with BetterBatteryStats or similar now you have root to see if there's anything in particular using the phone during idle?
How do I turn off Digital Wellbeing?

I can but from what I heard in one of the TG groups today, BBS isn't working properly due to changes in Android 12.

Go to settings, Digital Wellbeing and turn off all the options if you turned any of them on. Go to Settings, Apps and then find digital wellbeing and remove all permissions, then within that section also wipe data for Digital Wellbeing. That pretty much resets it back to stock. Without root, you can't freeze the app or remove it but this should be good enough.

Ah, damn.
Guess it'll be 'top' or 'htop' in terminal then for now.
Mine lost about 7% overnight last night. I've read on this forum that they aren't sleeping well. With two adb commands I installed Nap Time by Francisco Franco and it seem to be going into a deep sleep when not being used now.

I've got NapTime as well. The trouble is light and deep doze is just the Android OS restricting what apps do and forcing them into maintenance schedules so things are done in batches. So its an app thing rather than a low level forcing of the phones CPU to sleep, so even in light or deep doze it doesn't guarantee that Android has been halted and the CPU is in sleep, that is another thing step. It should make Android more likely to suspend and the CPU to go to sleep if Apps aren't allowed to chatter over the network, but deep doze doesn't guarantee the phone has gone into standby.
Other things can prevent the device from truly suspending and putting the CPU into sleep mode, so other things may be happening, it might not be an app issue.
To check how long the CPU is in deep sleep (essentially the phone is off and Android is suspended and is what we need to see so top battery drain overnight) CPU Spy can show you that, currently mine is showing 82% deep sleep overall. When you see a low percentage of deep sleep and high percentage at 300Mhz, then something is stopping the phone for sleeping, so it is kept awake doing little so idles constantly at the lowest CPU clock speed, but this still uses quite a bit of power compared to deep sleep.
The age old question for those of you having battery drains, Did you turn off wifi scanning?
