Desire Battery Life

I've heard some people say they get 3 days out of their desires and others saying they get just over a day.
This thread it would be great to collect a list of people with desires and their average battery life as well as a list of apps they have installed and widgets on display and maybe the rom they are using.
Just trying to work out
I'm going to collect data and put something up tomorrow - but I noticed last night that my battery went down really quickly when my Alarm went off (using Gentle Alarm) I also confirmed this using JuicePlotter which showed the battery sharply decrease just at the same time in which my alarm was set to go off.
I also noticed that having wifi turned on didnt seem to effect battery life that much...

Yeah my battery lasts really well leaving WI-FI on too. Not sure why others have an issue with it.
My battery will last a day tops turning on from 7.30 and off again around 12am ish
During day I will use Seemic (on manual update) and use FB on net every now and then.
May occasionally go to the Market for Updates.
I only use mobile Network when I need to so I turn off and on when required.
I will play Word Up and Solitaire for 30 -40 mins a day roughly.
Battery % will vary between 65 - 45 by 6.30 pm
Today it is down to 75% at 2.10pm - although I've not played any games today so far.

I bought an X10 and returned it because the battery wouldn't last even a day despite having all kinds of task-killing crap installed.
Then I bought a Desire and had the same problem - 6, maybe 7 hours of battery.
I found a post on some obscure blog that helped me track down the culprit: there are apps that don't let the device go to sleep completely. I had two of them. And Android (at least the HTCs) have a built-in function to see exactly what those processes are:
From the dialer: *#*#INFO#*#*, choose Battery History from the menu and then Partial Wake Usage. Nothing should have more than a tiny fraction of a bar. But on mine, Grooveshark was using 99%. I uninstalled it, tried again a few hours later and saw that Mikandi was using 99%. I uninstalled that, and now I'm getting more than 24 hours of heavy use.
Some apps just don't behave.

Why would Dialer App have such a high network usage?
It shows up as using a lot of network!

Wouldn't the dialer use the network to call people when you dial?
Thanks for the "cheat code" on the hidden menu. Very interesting.
I can sometimes squeeze 2 days out of my battery. I'll only get a day and a half on this charge though because of lots of txting and facebook use.
I found this menu option in Settings > "accounts & sync" > Background Data. I turned this off and seem to get a little more battery.
Changing the brightness down a bit helps, and i'll set the screen timeout to lower as its at 1 minute now. Plus If I use friend stream instead of the facebook widget then it updates when I want to and doesnt keep active.
Least amount of battery time i've had is a day. I never turn my phone off.

I never get a full day out of mine, maybe 8-10 hours max... I have no idea how some people claim 3 days, I'm not exactly a power user!
Stock ROM (not a provider one, just generic) on T-Mobile UK network
Wi-Fi and GPS off
Widgets: Standard Flip Clock, SMS, FriendStream, Stocks (2hr update), Agenda, News (2hr Update)
Market Programmes: K9 Mail (1Hr e-mail updating), ES File Explorer, Shazam, Voice Search, Pkt Ebay, Tricorder, UK TV Guide, GBCoid
In Standby (screen off), not using web, not calling, not texting, not using apps, I lose around 10% per hour, faster if anything at all is on.
Oddly, despite the very poor (for me anyway) standby life, in call life seems really good, I made a call last night for an hour, where phone was in the orange phase when I started and still hadn't gone red at the end...

I wanted to try turning background data off but sadly the market does not work when you have this turned off (a warning pops up when you try)

True re the dialer. Was thinking network as on net use.

anyone got background data or mobile data turned off?
if so whats your battery life like?
also anyone tried with 3G on and compared to GSM ONLY?

Well the only app that have a bigger bar is Android System... Is this normal?

Settings ; About phone ; Battery ; Battery use and it will tell you when it was last unplugged and what has been using it.
4h 27m
Cell standby - 45%
Phone idle - 45%
Wifi -7%
Android system - 5%
Display - 2%
Obviously you can see from that I've hardly used it. A few texts, checking email periodically. Display brightness is on full, weather update is set to manual. Only have a few apps installed. Main one being data counter widget.
2000kb wifi
780kb cell.
Oh, and SystemPanel, tells me I have 93%.

Switch off 3g when you don't need it,this can nearly double your standby/idle time ,use a 2g-3g toggle if its a pain.
Juice defender with its plotter can give you very useful info on when your phone is using its battery the most.
On idle with 2g 1% per hour is normal, with 3g 2-4 %.
As soon as that screen goes on start thinking 15-20% per hour!
Most smart phones are the same,my x1 ,touch pro all got caned when I first got them,but a bit of experience and a few tweaks later they were doing 3-4 days.
Also flatten it and fully charge it when switched off helps too.

My battery life is pitiful too, im a pretty light user now ive had time to play with the phone for a while but battery will always need to be put on charge by around 10pm when only unplugged around 7am the same day.
I bought up the partial wake usage list and UID followed by a number is using twice the power of Android System.
Does anyone know what the UID is?

My battery life was rubbish until i updated the radio version to 32.37.00.32U_4.06.00.16_2. I am also using MCR3.1
Before my battery life would be fully discharged within 7 hours. Now i have 1day+ Not too sure as i now have a brodit car mount that charges my phone during my commute.

To update, do you need to root your device? I don't want to root mine, but I want to get the best battery life possible.

Stating the obvious, but if you don't use your phone, your battery will last a long time!
Personally I need to use my phone (otherwise why would I have bought it) so have push email running with full Exchange sync 8 till 8, FB & Twitter syncing once an hour, spend a couple of hours a day making calls, connect to WiFi using my iPass account whenever a hotspot is available and spend a lot of time dealing with emails etc.
I put my "less than a day" battery life down to the fact that my screen is on and doing stuff for much of that time.
Of course if I just leave the phone on the desk at the side of me and don't touch it all day, even with push mail and all that sync, if the screen is not turned on much, I get 2 days.
It's the screen that eats the battery. The more it is on, the shorter the time between charges.

Wow I don't understand how you people get such amazing battery life!
I am no noob anymore regarding Android and Smartphone's in general, so I understand most 'hints & tricks' in this thread. But simply for me this does not work.
Some important stuff:
- I ALWAYS have 2G on, never 3G.
- I use wifi at home and in most places I go
- I have almost everything set to 'manual' updating
Ok.
For example my last situation:
I unplugged it at 23.30 yesterday. I used it for a little bit, over wifi. Checking twitter, surfing the web, watching some video's in HTC Flash Player. I went to bed around 02.00, watched some Law & Order that's why it was so late. So before turning off the lights, I turned wifi off. The battery was around 80-85%, from what I remember.
I wake up at 12.00. The battery was still above 50%, that's for sure. I do some facebook, twitter, news, etc. All over wifi.
And now, just before 17.00, my battery was dead (while I almost typed this entire story on my Desire -.- I was pissed). So that means, about 17 hours? Which about 10 hours I slept and the phone was doing nothing, over 2G!
So yeah... and when I read all your story's about 2 days (48 hours) I am really like: WTF
Some more details:
-No live-wallpaper. Just the black 'carbon' one.
-I used to use LauncherPro beta, but battery life was just as bad. Now I am back on HTC Sense. I have some widgets, like the Calander widget, a small music widget, bookmarks widget, etc.
-I tried to find out what uses the most battery while sleeping with that code and it showed Android System. So nothing weird there.
-Again, everything set to MANUAL updating
-ONLY 2G.
-Brightness set to auto.
So really, I think it's my wifi that sucks the battery life out of my Desire. I remember when I went on a trip and was just 'listning' to music, my battery only dropped like 10 to 15% in 3 hours.
-----------
Btw, I remember that this 'some people have great battery life some people don't' story was the same with the HTC HD2. The only different thing there was that I was one of the people with the 'good' battery life. Now I am on the 'losers' team
Any help would be great!

battery life of note 8

I have AT&T LTE version on rooted 4.1.2 with Greenify and I'm about the same, 5 hours of screen time with data off. It's not great battery life, but not sure that I can do much to improve it.

so do you think thats normal battery life but some say to get 8 hours surfing web on wifi

My device is new and I've tried breaking in the battery. Rooted it and froze any potential battery killing apps. Use it on low screen brightness. Getting 5-6 hours screen time. I have to believe that its normal, but I can't say 100% for sure.

I believe the Note 8 with LTE tends to drain battery faster because of radio feature. I have a Verizon Galaxy 7.7 that also drains battery faster than the non-LTE version.
My Galaxy Note 8 (non-LTE) gives about 9 hours with wifi on and 40% brightness. However the tablet is non-rooted (if that matters).

Yes, data over a cell network uses more power than over WiFi.

There is no such thing as "breaking in the battery" for this type of battery. Li ion batteries do not need to be conditioned like the old NiCad type batteries.
All I would recommend on a new device, is to calibrate the battery meter on the phone itself: charge to full, leave it on the charger to ensure any top-off charge is achieved (maybe 30 min or more after "full" is indicated). Than drain to 10 or 20%. This sets the "high" and "low" flags for the battery meter, so the meter is more accurate. But it doesn't change your actual battery life (just like fiddling with a car's gas gauge doesn't mean there is magically more gas in the tank).
After calibrating the meter, the best thing for battery life on a Li ion battery, is frequent short charges, as opposed to full discharge cycles.

Same Issue
Same problem here. I have 9 month old Note 8.0 wifi only. Battery life has always been atrocious. Drains 1% every 1-2 minutes of basic use By basic use, I mean internet browsing, 20% screen brightness, no other apps open, all major tasks killed. This is absolutely pathetic for a $400 tablet. If I play any sort of game, such as Candy Crush, we're talking 1% every minute. I've never gotten through an entire movie.
I finally got so fed up that I sent it in to Samsung for service. I haven't gotten it back yet, but I received an email back saying the repair was a "software upgrade." I find that hard to believe. I will post again with the results after I get the device back. My satisfaction with the Note 8 is a 1 out of 10. I wish I would have gotten an Ipad mini or Google Nexus.

I find it unusual that some of you guys have abysmal battery life. On my Note 8 I get amazing battery life, with average to heavy usage I don't have to charge it for a couple days.
I also only got it a couple weeks ago; maybe Samsung changed something inside the Note 8 since the release earlier this year?

I have a Note 8.0 WIFI that was made as an early release US model.
Like any Phone... Apps, GPS, WIFI, SD card, and Screen brightness all are factors in power drain.
I try to stay away from apps that have ads built in. Even small tickler or banner ads can cause battery drain and privacy issues.
Even though you may not see the GPS indicator being active, apps will poll GPS time to time.
In testing some apps, I found that most banking apps are too taxing on my device. Believe it or not Paypal, and Chase are real buggers to your privacy and consume more than what their apps are worth.
Bone stock with no SD card, the device consumed a lot of battery power between the first few power cycles.
I figured there must be a lot of services running in background to optimize and finish configuration of the OS.
Once that settled charging and running on battery smoothed out.
I am able to get 10% drain per hour on normal operation. WIFI always enabled, SD card installed, and lots n lots of apps installed as well.
Just surfing with power saving enabled, LEDs on, Eye watch activated, SD card installed, GPS enabled, and brightness on auto at +3, I can get about 5% battery drain every 40 to 45 minutes.
As for videos using internal speakers, I get 10% drain every 25 minutes... As the display brightness increases and speakers are at 3 with full Viper optimization.
To me being the slimmest and lightest 8 inch device, it gets pretty good battery time. One thing to note, if you feel the left side getting warm... it means you consuming power and to expect the battery to be consumed much faster.

Hi,
I have N5100 too bought from indiatimes.
Here is what I did to get better battery life out of my note 8.0
1) Go to Settings -> Developer options - > use 2 background processes
2) Do not put Auto brightness, Set the brightness to 20% it will be still be good enough
3) backup and reset - > uncheck everything
4) Google account - > put sync on first in the notification bar and then go to your google accounts and uncheck everything, then disable the "auto sync" from the notification bar
5) Sound - haptic feedback off , vibration , move everything to minimum ..
6) GPS - off , use only when required
7) Developers options - > unknown sources (check only when you need , otherwise uncheck it ) , verify apps - uncheck it
8) Open Google maps, go to settings , uncheck the location services
9) go to youtube app - go to settings - uncheck anything that has syncing options
10) Screen time out 30 seconds
11) Since you said you mentioned that you are using Greenify . I am assuming you are rooted. So you can greenify almost all apps except the launcher and the ones which you use frequently.
12) you can use Rom tool box pro or root cleaner to freeze ( maps , google contact sync, bookmark sync, yahoo finance, hangouts (if you dont use ) , kies , talkback, chrome, google play music , google + , alarm , drm , samsung account , samsung push , samsung print , weather widget, sns, fw upgrade , yahoo news
13) use system control pro app where you can set the governor to pegausq min 200 Mhz, and max 1600 Mhz
14) Go to settings - more settings - Mobile networks - use GSM mode , dont use both WCDMA/GSM
15) Go to google play - > settings - > uncheck auto update apps and also notifications ,,
16) Go to all the google apps and check for any settings that use frequent checking.
17) Use UC browser it is really good for browsing and many options.
18) When charging the Note 8.0 charge it from 0 to 100 in one stretch and dont connect to charger unless it drops below 3%. If it is getting switched off by itself no problem.
19) Go to settings - > Date and Time - > Uncheck everything
20) Go to Settings - > S pen - > Check the option - > Disabling pen detection when pen is attached can extend battery life.
Clear everything in memory in RAM before you leave the note idle.
Before you can do all this. It is better you install the right firmware.
For me XCMH2 gave good battery life. Now X note build. Below is the link to that thread.
http://forum.xda-developers.com/showthread.php?t=2345299
Wipe data , wipe cache , wipe dalvic cache , do it two times in that order.
then you flash the X note build and go through all those steps.
If you do it right I am sure you will not have many wakelocks and you will get better screen on time than 5 hours.
when I did all this the highest I got was 9 hours 26 minutes (7 days).. few months. On an average I was getting 8 and half hours..screen on time with 6 days battery life .. Max standy I got was 15 days battery life with 7 and half screen on .time ..
Your note has to sleep when you are not using. then you can get good standby time and also good screen on time.
) Note 8.0 is really an awesome device. Enjoy!

Woah! That is way too many things to adjust... Get greenify app, and startup manager app... and be done with it. I get 8% an hour and 12% an hour with miracast movies to my tv. Having sync on... to go and do sync settings manually is a time consumer... just turn off sync at the quick buttons. Make sure blue tooth and Sat are off. Brightness is manual setup to be be bright enough to give good detail and whites on movies. I leave it alone so it is never an issue on adjusting for most lighting conditions.
I added a simple tool to give wifi data speeds... so I can see how often high rates of data are downloaded. Most of the time small packets of data are always being sent for network discovery and authorization, along with apps like email and what not.

Gosh, I have been posting bits here and there, and nobody cares until now. HA!
OK, I will do a simple rundown.
OEM or stock firmware only.
Saferoot
Xposed framework
Wanam Xposed
Startup Manager for Xposed
Greenify Plus for Xposed.
Geenify
Security 360 Antivirus (Very robust app for its size, like having 5 apps in one)
Trickster Mod Pro
RootCloak and Substrate (Non-Xposed version)
Now that I have the main components listed, what to do.
Turn off in Application Manager... Will require swiping all the way to All.
Google Play Music - If updated you will need to uninstall before turning off.
Google Contacts Sync
Briefing
Clock (digital)
Favorite Apps
Flipboard
World Clock
Yahoo! Finance
Yahoo! News
In Greenify, tap on menu. I have added an Xposed module to make all apps have a three dot or line menu, so you may not see the menu without it, as I have no clue to what any app looks like without the xposed module running. There should be an option to create a shortcut. It will place an automated greenify all launcher. It will greenify any app that can be put to sleep. In settings you can do experimental options to greenify.
Both greenify and security 360 have a sleep or end function, they work together at eliminating apps from running in background and memory starvation.
If you find an app that is always running after boot up that you may not be able to manage in either app, Startup Manager in Xposed may offer a startup disable for the app, though not all apps are covered in the list. It is fairly simple just tap on the app and once it is highlighted it will not start during startup.
Security 360 will allow further actions, though it has an easier interface than greenify. You can add both user apps and system apps to the ignore list or remove them as well.
I would be very careful on removing system apps from the default list.
With all that set I keep everything setup automated... email, wifi, and syncing.
Though I keep my google account setup to not do much but sync calender for syncing Samsung calender simultaneously.
Once you kill all the google automation in your online google account... you may remove Google +, as I never liked it and don't use it, the options on your tablet will be in effect, so make sure what settings you have on your tablet are what you want before making online changes.
I left Samsung account active so I can get automated updates. With everything else pretty much running nicely without any glitches.
I have my powersaver setup with everything enabled, and no automatic dimming. Pretty much like the previous poster I commented on. 20% is more than enough for my viewing conditions.
With my settings the way they are, I use the tablet without thinking of turning this or that on unless I am using miracast or file sharing.
PS... I have GPS on for apps that require it. Even though it is enabled, it is off until I start an app that needs GPS location info. It seems only 4 apps that I use pull from GPS. Google Maps, HD widgets,YP, and a Navi app. I have disabled internet location settings, as they are unimportant. Knowing which apps will pull location info during use makes it easier to control location than expecting games and browsers tell me what they are doing.

Hi,
I have N5100 too bought from indiatimes.
Here is what I did to get better battery life out of my note 8.0
1) Go to Settings -> Developer options - > use 2 background processes
2) Do not put Auto brightness, Set the brightness to 20% it will be still be good enough
3) backup and reset - > uncheck everything
4) Google account - > put sync on first in the notification bar and then go to your google accounts and uncheck everything, then disable the "auto sync" from the notification bar
5) Sound - haptic feedback off , vibration , move everything to minimum ..
6) GPS - off , use only when required
7) Developers options - > unknown sources (check only when you need , otherwise uncheck it ) , verify apps - uncheck it
8) Open Google maps, go to settings , uncheck the location services
9) go to youtube app - go to settings - uncheck anything that has syncing options
10) Screen time out 30 seconds
11) Since you said you mentioned that you are using Greenify . I am assuming you are rooted. So you can greenify almost all apps except the launcher and the ones which you use frequently.
12) you can use Rom tool box pro or root cleaner to freeze ( maps , google contact sync, bookmark sync, yahoo finance, hangouts (if you dont use ) , kies , talkback, chrome, google play music , google + , alarm , drm , samsung account , samsung push , samsung print , weather widget, sns, fw upgrade , yahoo news
13) use system control pro app where you can set the governor to pegausq min 200 Mhz, and max 1600 Mhz
14) Go to settings - more settings - Mobile networks - use GSM mode , dont use both WCDMA/GSM
15) Go to google play - > settings - > uncheck auto update apps and also notifications ,,
16) Go to all the google apps and check for any settings that use frequent checking.
17) Use UC browser it is really good for browsing and many options.
18) When charging the Note 8.0 charge it from 0 to 100 in one stretch and dont connect to charger unless it drops below 3%. If it is getting switched off by itself no problem.
19) Go to settings - > Date and Time - > Uncheck everything
20) Go to Settings - > S pen - > Check the option - > Disabling pen detection when pen is attached can extend battery life.
Clear everything in memory in RAM before you leave the note idle.
Before you can do all this. It is better you install the right firmware.
For me XCMH2 gave good battery life. Now X note build. Below is the link to that thread.
http://forum.xda-developers.com/showthread.php?t=2345299
Wipe data , wipe cache , wipe dalvic cache , do it two times in that order.
then you flash the X note build and go through all those steps.
If you do it right I am sure you will not have many wakelocks and you will get better screen on time than 5 hours.
when I did all this the highest I got was 9 hours 26 minutes (7 days).. few months. On an average I was getting 8 and half hours..screen on time with 6 days battery life .. Max standy I got was 15 days battery life with 7 and half screen on .time ..
Your note has to sleep when you are not using. then you can get good standby time and also good screen on time.
) Note 8.0 is really an awesome device. Enjoy!

Glad to know your battery life improved and you can try for even better screen on time and also in terms of days. I have put up some screen shots for your reference in the attachment. Please check.
I forgot few tips there
Converting Google play services,
Google Bookmark Sync,
Google Contact Sync,
Google Calendar sync
Google Chrome
to user app (they are system apps)
but not to worry, you can convert them to user apps.
what you can do is
1) Uninstall Google play services and Google chrome that came installed with the firmware
2) Install Google play services and Google chrome from aptoide.apk app , convert it to user app (in case if it is showing in system app)
How to convert Google play services to to user app?
If you have ROM toolbox pro latest version 5.9.5 or 6.0.3 you can open app manager in that , then just do a single click you will have bunch of options, swipe your screen to right then you will see more options where you can see below there will be option , convert to user app
3) Xposed frame work (latest version)
4) download and install call recording mod (if you need, its worth)
5) download and install greenify and check the option in xposed frame work (activate it)
6) Install Android firewall
once you convert all of those system apps to user apps, freeze them.
Google play services - dont freeze. freeze the rest ..
Max battery life achieved on my Note in terms of days was 15 days but i lost the screenshot , my second highest was 11days and odd..
Note:- I don't use power saving, flight mode , no battery doctor , no wake lock detector.. I use ONLY greenify with Xposed framework and I freeze the battery sapping apps.
Before turning off the screen, I make sure I have closed all apps from recent apps and then clear some ram from task manager just to ensure there are no wakelocks.
So far it worked out wonders and my battery life is excellent and very happy with my Note 8.0 after 11 months of usage.
Battery drain is 1% or may be 2% in 10 hours standby .. and that helps in prolonging battery longevity over 4 days , 7 days , 10days or even 15 days.. If you have battery drain overnight then your Note will come for 1 or 2 days but by curbing the battery drain over night you can get it running for 4 to 7 days easily with excellent screen on time.
I am currently on firmware X-Note 5.1 4.2.2 and use my Note for watching Videos, Songs, games, reading Flipboard, Google play stand, S-Note, PDF reader , editor ,
I got screen on time of 11hrs 12min in 4days 20h..., previous highest screen on time was 11hr 6m, and before that 9hrs 26min (stock firmware)
XDA developers is great forum, after going through lot of posts by developers these are the tips that worked wonders. converting system apps to user app was something I found out from other developers in XDA , i was hesitant at first but when I did it eventually I was extremely satisfied and you can see the results.
I hope you can get ever better results..

Bad battery life

[Q] What exactly does battery saver mode do?

All I can find are vague descriptions. Nothing saying what exactly it's doing. From my experience thus far it's doing nothing. I am not getting better battery.

From what I know it lowers the CPU clock speed and decreases brightness. All with the intent of saving battery.

I read that while it DOESN'T limit the CPU, it does lower the brightness and cuts out your data/BT/location/NFC in order to preserve the little bit of battery.
Edit: And syncs.

I don't think it actually does any of that though. I have been using it a lot the past few days half on half off. I still get all MMS and emails right away plus my photos are syncing with google. My brightness doesn't change (auto or not). plus I have BT and WIFI on all the time for smart watch and of course data usage . Maybe the processor, but im not even sure of that. Guess I could do benchmarks with it on and off and see. I just feel like this feature is doing nothing at this time. On my nexus 5 I could really see the processor throttle and brightness him with battery saver.

Mine only does that under 15% battery. Seems like its doing nothing over that.
Sent from my LG-H815 using Tapatalk

The default is under 15% and when it kicks in, i definitely notice a difference in the phone.
You can change it to immediately from 15% and i bet you will notice a difference at any battery percentage.

Cpu speed is not affected, just checked this.
Brightness was indeed cut off considerably, haven't checked for other things yet :good:

I figured out why it wasn't working for me. Simply clicking the icon to green in the pull down only enables it when it gets before 15 percent. Didn't force it on now like I thought it was.

Why is there so little discussion on this feature? I found very few threads on this and this was the most active conversation even though it is so old. I found out today I could enable this feature at anytime, not just at 5 or 15%. So I have it enabled at 100% battery and testing today. Upon enabling battery saver mode and restrict idle apps, the screen immediately went dim. I turned it back up slightly. I also noticed apps acting different. Toggling between apps is quicker and the animations are gone. Also, I'm using chrome and it's acting different. It's hard to explain, but if I'm navigating from one website to another, it is feels like it is refreshing every time, it doesnt feel faster. Im not sure what it is doing but someone with more experience will probably be able to pinpoint exactly what is happening. It's not standard chrome behavior.

Not sure with the Chrome part of it. I use a different browser. With FireFox everything feels about the same as before.
I also noticed the animations are removed so there is no fancy domino effect or sliding going on. It's all instant and to be honest it feels heck of a lot quicker this way.
Screen is much more dim and is extremely conservative for the most part.
Clock speed is the same. Although I wonder if there is some sort of under the hood change such as MPDecision switching over to battery saving mode. It personally makes no sense to leave it as is considering in the past it use to cap the clock speed.

So using battery saver today along with restrict apps in background, the former definitely shuts down background data. I noticed Google play store not authenticating paid for apps. I had to go to the play store to launch the app and re-authenticate. That is where I received the warning that background data is off. I have a weather widget and that does not appear to be updating as that uses background data. I have a barometer widget and that does appear to be working as that uses sensor data. All that is required to re-enable background data is to uncheck restrict background apps under the battery saver mode. As of right now, I am at 71% battery and 2 hours 14 minutes screen on time, 3 hrs 53 minutes on the battery. I'm mostly using chrome while screen is on and podkicker and listened to about an hour of audio and a little bit of teamspeak usage with my Bluetooth headset. Brightness is at 37% which is pretty dim in this mode. I'd say it's equal to 15% in regular mode bit good enough to see.

Update, I went all the way to 25% battery remaining yesterday and I had right at 5 hour SOT. In my opinion, this mode is not worth the hassle. Background data is off and that breaks a few things. Screen is pretty dim and I ended up turning it up anyway. I have had similar battery life in the past anyway. I have had 7 hours 20 minutes of SOT before without this mode on and all my widgets working. I'm going to leave this mode off.

It saves battery

yup..i feels like the batrey saving mode is draining more batrey life than not using it..is there a solution for this ?

Anyway to stop this horrendous battery drain?

I have wifi/bluetooth scanning OFF. What else could it be?

I'm not sure on this one....you have to have an app somewhere that is killing your battery. My phone normally gets almost a day and a half easily. With Wifi and bluetooth constantly on, watching YouTube videos, and even screen sharing to my TV. Go through your Apps and find the culprit that is killing your battery.

go back to stock, watch drain for a couple hours install an app, rinse and repeat until you find the culprit.

Here, personalization service uses the GPS the most, but I don't know all the related Samsung apps that depends on it.

Same problem here, i dont use too much my phone, not gaming, not videos, just social Network and the telephone dont reach the 5 1/2 hrs screen time, most of the time is on standby, the WORST battery of all my phones in years.

Those with battery drain issue, are you guys using the Exynos version? Mine is Exynos and the battery drain is crazy since day one

Try this, it doubled battery life for me, especially since I spend the majority of my time connected to WiFi.

I'm using the Exynos version and not noticing abusive battery drain.

wifi will off mobile

technically, when you connect to WIFI, mobile data will not be used.
Except you turned on the use Mobile Data if Wifi connection or signal is slow/weak option

I had the same problem... Multiple factory resets and setups later, same problem. Was ready to return the phone because System was using WAY more battery than Display and I was averaging 2.5-3 hours SOT to 5% battery. Found someone suggest Bixby problems in another thread, disabled all Bixby related apps and now battery drain is gone, regularly getting 7-8 hours SOT with no problems.

Additional screenshots (first battery screen is before, second is after disabling all Bixby junk)

Bixby doesnt even show up in battery usage. Should I still be concerned. I Bixby voice is disabled but routines and the Bixby homescreen is still enabled.

One interesting thig I see in you first(high use) screen shot is the amount of battery used by adguard, where as in the subsequent image it doesn't even show up.

Because all traffic runs through adguard, battery stats are skewed when running it. It tells you this when you first activate it. I wasn't using it when trying to isolate my battery troubles, but I'm back to using it 24/7 and still get 7-8 hours SOT, so it wasn't the cause.

Bixby Voice Wake-Up was a huge drainer for me. Find it in apps, doesn't show up on battery stats page, but when you pull up app stats, it'll show how much battery it's used since last charge and for me it was crazy high.

This phone has had the best battery life by far of any I've owned. I'm on the US version unlocked straight from Samsung, using on T-Mobile network. Use it all day at work, been at work playing games and making fantasy football moves on my phone all morning for the past 6 hours and am still at 75% (and my battery widget that uses the system algorithm says I still have 14 hours remaining at my current usage level), and I use Always On Display on ALL THE TIME. Has to be related to an app or something. I will say though that I installed sideActions and disabled all the Bixby packages (along with several other Samsung-specific packages) since day 1 using CCSWE App Manager. I'm not a light user, either - I have Nova Launcher, several KWGT dynamic widgets, Tasker, AutoInput, etc...
Do ensure you have battery optimization turned on.

Note 10+ EXYNOS - Battery Life on Android 10 One Ui 2.0

Now that the official build is out we can start monitoring how the battery is behaving.
Personally since the first Beta I was amazed with battery life, especially for an early stage software. Refinements has been going and I can get outstandinh results that weren't possible before.
I'll start with few screenshot and eventually update my experience.
Here's some details:
My device is Note 10+ SM-N975F (Exynos) 512GB build version BSL7 .
Brightness is set to auto, poor/average cellular signal strenght, always on WQHD+ and only battery saver options are the ones from Samsung with not so many tweaks in the settings. Most usage on wi-fi but 4G+ for a discrete 20% of the time. I never close apps in the background. Some screenshots present some abnormality due to Adguard filtering my internet traffic, I have local VPN always on. AOD was off the whole time since I setted Bixby Routines to turn it on only when charging. Sync was turned on all the time, GPS always on too, Bluetooth used for about 1 hour with Galaxy Buds. One Gmail e-mail in push. I have over 200 apps installed excluding system ones. My DPI is set to 598, my launcher is nova, I theme with HEX Installer, use One Hand Operations+, Whatsapp always syncing with my laptop.
Digital wellbeing shows about 70 unlocks and 220 notifications, inaccurate data but roughly exact since it counts some of the ones from the previous charge in the previous day.
To monitor my battery I use Gsam battery Pro, the Galaxy Lab "Battery Tracker" plugin and the stock battery monitor on Device Care.
Since the charge lasted more than 24 hours, Battery Tracker (Galaxy Labs) doesn't show the beginning of the discharge curve in the final screenshot so I attached one I made when I was at 40%. Remember Adguard battery consumption is miscalculated by android system, the Adguard app tells me it consumed 1.5% in the last 24 hours.
Feel free to upload your results and details let me know if you want further informations on my setup
