my galaxy nexus's screen is draining to much battery - Samsung Galaxy Nexus

hey.
i bought a new one like 3 days ago, rooted and installed android revolution HD custom ROM.
which says makes the battery better and has a custom kernel so im not overclocking my processor or anything.
i even fully charged to 100% and wiped all battery stats with CWM.
on my battery stats page it says my screen is using 50% of my battery and when i press it it says its been on for 2 hours ( out of the 14 hours my phone has been since i charged it )
thats too much battery drainage going on here.
any help ? or suggestions ?
oh i also have my wifi on and my screen brightness set to the lowest possible

This is normal just read over threads....

You never mentioned what your final battery level was after 14 hours and 2 hours of screen? The "50% used" means 50% of the battery used to that point.
FWIW, I'm showing the following at the moment:
78% battery remaining
3h 51m on battery
Screen: 62%, Android OS: 17%
Screen on time: 1h 17m
So, based on this, I'd expect to get maybe 15-20 hours of charge and 4-5 hours of screen use out of a full battery, which is about right.
Daern

Battery life of a brand new device is always going to be a little poor.
Here's what I do: Charge it up all the way when you first get it. Then run it down until you get the low battery warning. Then charge it up. Then use it normally.
After a week or so, your battery life will normalize and should be much better than the first couple days.

alright
i will wait until its on 5% or so and charge it to full again.
my battery is on 48% now after 14hours of use
2 hours screen ( 51% screen usage )
android os 15%
notice that im running with the minimum screen brightness which is not what i want to be on most of the time =/
but i have wifi on AT ALL TIMES, it doesnt drain as much battery as the screen.
anyway i will wait for the battery to normalize like one of the users said and see what happens.
thanks a lot

it's normal for android phones or any phones for that matter.

48% remaining after 14 hours, with 2 hours screen on is pretty good actually, especially if you have had the phone under a week.
You will find the battery get better after half a dozen charges
Remember, its a 4.6inch screen with hd resolution, that's a big hi res screen by any stretch, and will use a bit of power

The ARHD ROM is a good one, and you'll get excellent battery performace, especially if use with the James Bond kernel and undervolting settings. But to lower your screen battery drain, use a dark (or plain black) static wallpaper and auto brightness.

standard nexus , no rom kernel or GPS and Bluetooth, twitter Facebook and Gmail set to push. Playing games and listening to music , brightness 100%.

It's a 4.65" 720p for science's sake... based on your stats, you would get 4 hours of screen on time from a total of 28h on. What did you expect ? 10 hours of screen on time ? Sheesh... Where did you come from ? iCrap ?

Dunno, for me GSam says that the turned off screen takes almost 4 times more than turned on. I know how it sounds, but having screen drain about 20% from all, though it worked for 20 minutes of 2 days. And the common battery life if not too bad - about 20% per day. I cannot find the reason for already three weeks, how this could be?..

When you have drain like me then you can complain . I have yet to figure out why my battery drains so fast, it ranges from 10-15% an hr while its just sitting there.

ie: if it says that the screen is draining it 50%, it means that 50% of the power drain on the battery was caused by the screen, it didn't drain your battery by 50%. The screen is the biggest power hog on most smart phones so your stats seem pretty normal.

Well, the drain is not big indeed Just to ensure, that it could happen at all and find out, what it could be - kind of perfrctionism
Just installed PGM, assuming it will change the statistics. Let us see how much.
OK, after maybe a day with PGM I should say the drain is same - about 1.5% per hour (with radio turned on). Trying to be more tolerant to drain now

Battery Stats Thread

So I was wondering if anyone who has their device already could post some screenshots of their battery usage, screen time etc?
I know there have been some thrown around numerous thread but just thought it would be useful if people would post in one place?
Thanks
just wanna share some battery life stats..
1st power up of the phone.. did a full charge with phone off, once charging light changed to green, i powered up the phone.. 1st thing i notice.. it is not fully charged to 100%..
next thing to take note, the entire duration the phone is on is an additional hr plus.. i rebooted the phone once so im not sure what is the actual duration the phone is powered by the battery..
all in all, about 3hr+ with high usage of the phone.. notice how the phone was awake most of the time and the screen was on most of the time too..
cheers..

Only if this phone had some decent battery packed in, as in the Note, I'd have grabbed it. Why HTC why ?

Whats your screen on time?
1st post so I hope it's helpful.
I'm a big fan of the phone & love it, there are a few small issues I've noticed & I'll post these in the relevant thread.
People keep saying the battery life is dreadful but it doesn't seem much worse than my original Desire on similar use.
After the first full charge last night I plugged in the charger when the warning came on at 9%:
11 hours 2 minutes on battery, screen used 75% of the power while on for 4 hours 31 minutes.
Everything else used a few % each.
Brightness was on auto at approx 50% most of the time and on full for about half an hour; indoors I wouldn't want it as bright as that.
F/W 1.26.401.2

Hi
Thinking about this phone or the one s. Just a quick q regarding the documented poor battery. Could i go out for the day - say for 15/16 hours send the occasional texts maybe a couple of photos/videos and the occasionally browsing the web - to check football scores etc etc.. should this handle that ok ?
is a pocket charger the way to go ?

That's how I intend to use the phone tomorrow, so i'll soon let you know.
The thing with this phone that is superb, there is hardly any drain when your not using it. It's extremely good for idle power saving.
dunno about you guys but i'm getting insane numbers in standby...
overnight i lose 1% with wifi, data and autos-sync on....
it's the first android phone that sleeps properly when screen is off...there's nothing keeping it awake.
i'm on 1.26 by the way
Well I don't think it's that bad on battery given how much screen time i've had....three and a half hours.
Only got 2% left so going to put it back on charge. These are my final stats for my first day after a 13hour charge

Update 1.28 and Battery Life

Hi everyone,
I received the OTA update 1.28 yesterday (the Netherlands). My most important issue before I installed the update, was the battery life; the relatively high usage of the 'screen' in particular.
A preliminary report about update 1.27/1.28 said the battery life would improve drastically, showing screenshots of how little the 'screen'-usage was. Well, in my case the opposite happened; the battery life actually became worse. I think my max screen-on time is about 0,5h - 1h less than it used to be.
Here are some images of my battery usage. As you can see, it's running for 7h 34m now, and it's already hitting the 48%. My screen-on time being only 1h 9m. Didn't do anything power-consuming today as you can see; a little bit of whatsapping, browsing, etc. I propably won't even get 2 hours of screen-time:S

For those who already received the OTA; how is your experience with the battery life? Did it become worse as well?
Same here. For what's it's worth, it might even have gotten worse...
How can you comment on the update after 24hrs usage?? Give it a week and a few charge cycles and then see how it goes. Or, better yet, factory reset the phone and add apps one at a time - it could be a poorly coded app causing the issues

Well, the fact my battery life became worse could be due to a miscallibrated battery, in which case a complete discharge and full charge (or stats reset) might improve the battery life. If a poorly coded app caused the issue, the app would probably show up in the battery usage list.
That being true or not, the battery life will probably not increase compared to 1.26, because the screen is using a lot of power, relatively speaking (more than half of the battery life is being drained by the screen). I expected this 'problem' to be solved after the update, but I guess the screen (and GPU?) are just very power-hungry.
The OTA update didnt really impact battery life (still crappy )... Im now running ARHD rom and the battery life is a lot better!!
Custom ROMs seem to be the way forward for now.

Theres an app on the market called Power Tune-Up. Use it to see which apps are power hungry. On my Desire, i have found that some apps have a very serious impact on battery life.

2 hours on battery today and I have only put it down for a quick 10 minute lunch and (1hr 40 screen time) and i have only lost 13% battery! Not bad eh?
I've been off the battery for about 3 and a half hours and last time I looked, about ten minutes ago... it was on 90% battery... for over an hour I've been listening to music as well on it.
Though, my battery life was not actually that bad on 1.26 either, but for the moment I have no complaints about 1.28... even though the spare core might not be working properly yet for background tasks... so I can only hope that battery life will actually improve with time!

1h 40 screen time and you only lost 13% battery? So you have 87% left? That would mean you can get around 12-13 hours screen time!? :what: Post some screenshots please with screen time, overall usage and brightness settings.

After a week of having the HOX, I think im seeing some improvements to the battery.
Im at 48% left,
9:30 hours usage with 1:30 of screen time.
Took it off the charger at 09.00 this morning and now the time is 18.11.
Been calling, mailing, texting, some browsing and syncing offline playlists from Spotify.
Running 1.28 OTA, non root, HT23 model.
The one thing I do experience from time to time, is backlight flickering. It just seems to come and go.

I have 11% left and here are my results.
4,45 hour talk time

With 1.26 I have great battery life.
With 1.28 it's the same,great.
18 hours and still 64%.
Few phone calls,browser,and hours of listening to music.
Not bad at all.
I have a great HOX.

Battery life + great battery monitoring application

I just got my Glide a few days ago. From the specs of the phone and reviews online I was expecting the battery to last very long, but that hasn't been my experience.
My battery was going down about 10% every hour which means I would barely make it through a work day without charging it again.
I found a great app called Battery Mix that tracks battery usage and estimates how long the battery is going to last. It shows a number called P/H (percent per hour) which tells you how many percent per hour the battery is going down (or up if you're charging). You can find the app here: https://play.google.com/store/apps/details?id=jp.smapho.battery_mix
When I first installed the app I was getting about 12.5 P/H which means the phone will only last 8 hours. I then uninstalled a few apps that use battery, but that didn't help much. Somebody said their battery improved when they formatted their SD card, so I just removed the SD card from mine. Now my battery consumption is down to about 8 P/H. The best I've seen is 7 P/H. This is better but still would only get me 12 hours and I'm not running all the apps I would like to be running.
I have JuiceDefender running now on the balanced setting. I'm running the Osimood ROM with Android 2.3.5. I've removed all background network polling apps like Facebook. Android OS is using 56% of the battery followed by display at 15%, so there isn't anything else that's eating up my battery.
How is the battery life on your Glide? Could you please install this app so we can compare numbers?
Woah, 56% battery life for the Android OS?
On daily usage it barely gets above 20%. The screen takes most battery life.

Thanks for the info.
Mine has been sitting on standby most of the day so that's probably why display is so much lower on mine than yours.
The high percentage of Android OS doesn't really worry me. It doesn't mean it's using a lot of battery; it just means it's using most of whatever is being used which could be a small amount.
Mine is doing much better now. P/H is down to 4.3 which means it could last 23 hours.
I really think the problem was the SD card. I'll pick up a different one after work today and see if it works better. I need a bigger one anyway.
I also found a thread that talks about corrupt image or video files on your phone causing bad battery life. That could definitely be what I'm experiencing. Should be fun figuring out which image is causing the problem.
what about downclocikng your cpu to 800? it will help i belive.
OK just installed it. I will let you know how mine is doing in a few days. I am fully Rogers stock.
I replaced the SD card and it seems to be doing better now. There may have been images on that card contributing to the problem.
I actually had GPS, wi-fi and bluetooth on the whole time. I've turned them all off now.
I've also underclocked it to 800. Thanks, taiber2000.
It looks like for the last hour it only dropped 3 percentage points.
If you are rooted and have ClockworkMod installed, you can sometimes get better battery life by resetting your battery stats. I think there are even some apps for rooted phones that will do it, but I don't have any experience with them. I can say, however, that resetting my battery stats using CWM increased my battery life significantly.
See here for one guide on how to do it: http://www.droidforums.net/forum/bugless/111009-get-better-battery-life-reset-battery-stats.html
sjbotha your welcome.
i belive i will do the same when i'll get my phone as well. altugh i will install the OC rooted kernel for better overall performance i will still downclock via software, not need the extra sterngh for my uses and i better have longer use time then CPU power.
I get 4.9 but the other day I was getting 12. All I did was Reboot my phone and I haven't started many apps. I think when they start they stay in memory.

Mine depends on usage:
-about whole day wifi-on with 3 hours games and calls; if battery is 100% at 6am, it will be 20-30% at 10pm
-whole day HSPA+ on, 2 hours phone calls + SMS/MMS, emails etc; if battery is 100 at 6am, it will be 50-60% at 11pm or before I sleep...
in terms of P/H:
-i get 3-5 P/H when wi-fi, Auto-Sync is on.
-i get 2-4 P/H on HSPA + Auto-Sync on.
-about 1-2 P/H or sometimes a straight line on Battery Stats when Idle, no data connection and/or auto-sync is on.
in other words, the glide can handle my needs in a whole day without completely draining it's battery.

how is my battery life?

I'd say your battery life is pretty poor.
My battery is a little bit better. I don't have any screen shots right now, but it's usually around 3 - 3.5 hours on screen. Around 7-8 hours battery usage total.

Try downloading Gsam or watchdog from the playstore. Watchdog will tell you if there's a rogue app draining your battery and Gsam will tell you what's taking up the most power.
let your phone do a 3-4 recharge discharge cycles..then it would stabilize.

charge it to 100% then let it discharge(1 cycle of rechrge of discharge) although there maybe a better word to represent that(noob in complex english )..

With 2 hours screen on time over an 8 hour period and your steady curve on that graph, I would say you have some app, or some service eating CPU cycles constantly (these are called wake locks)...
Do this:
Download an app called CPU spy
Charge your device all the way
Pull it off charger
Open CPU spy
Then just hit the back button to close it.
Let your device sit for about a half hour. Don't touch it as much as possible. Leave the screen off.
Open CPU spy... post a picture of what your CPU stats say according to that app. Majority of your times should be in deep sleep mode.
Also, your battery shouldn't drain anymore than 1 to 1.5% each hour at idle. Unless you live in an area where there is poor reception (scanning for signal chews it up as well).
EDIT** ALSO...is your screen brightness on auto or is it manually adjusted a little brighter? If it on auto, then your battery life according to those graphs is absolutely awful. I have mine set pretty bright and I still see about 3 hours of screen on time

			
				

			
				

			
				
Give it a few hours of "normal" use and then come back here with a Betterbatterystats screen shot with Partial Wakelocks/Since Unplugged and Processes/Since Unplugged. That way we can see what is eating your battery. With only 4% gone, we can't see anything (too small of a window). Make sure you don't plug it in and use normally.
I have seen your other posts and I am wondering what it is that you really want out of your battery. If you think that you can get 3-4 days out of a charge, that is not going to happen. 1.5-2 days is a reasonable expectation and I think that you can get that, but you have to look at your usage habits. No kernel is going to fix that. No ROM is either.
If you are polling notifications (Facebook, G+. Twitter) or Google Locations (Maps, some app that requires location) or believe it or not using the XDA/Tapatalk app a bunch, then those will drain your battery quite fast. I use the Tapatalk app quite a bit and that and Google Now are my #1/2 battery drainers. Could I get rid of Google Now? Sure. It is more of a novelty at this point. I still get 1 -2 days of charge on my phone wihtout worrying about where a plug is.
Like I said, come back at the end of the day or tomorrow morning and post the Partial Wakelocks/Since Unplugged and Processes/Since Unplugged and we'll see what is draining your battery.
Another thing to note is that it seems your mobile network is typically pretty patchy. This can really drain your battery too.
I've been chasing wakelocks since I got my device and think I'm at a pretty good place. I get 2.5-3hrs of screen on time (about 20% screen brightness) across about 25hrs of standby time. Does anyone else get a lot of mmc1_detect and mmc0_detect wakelocks?
thanks woodrube. I will post my stats at the end of the day. I don't have a facebook or google + or any app that have notifications or updates by itself. I have the screen set to 20% brightness

			
				
how do I delete that dmux wake lock?

Is this battery usage normal?

In 3 hours, mostly standing by, it drops to 87%
I have no idea why "Android System" gets 23%

well, if you're not using the phone, with apps or whatever.. then something else has to take the place of the 'most used' application..
I hope this isn't the "omg android system is using all my battery" again that I seen all over the gs2 forums when it came out
attached is a screenshot of my battery usage, I been streaming music all day at work.. mostly wifi, screen on a generous amount of time.. browsing xda, internet.. even played around with autodesk sketchbook..
Just got the phone today, it's been ridiculous. I've recharged my phone from 20% to 95% twice today. Granted, I've been using it non-stop
Now at 65%. Just terrible!
Android System 38%
Screen 20% (time on only 2h 5m)
Android OS 11%
Facebook 8%
Cell standby 5%
I had a lot of sync crap turned on that wasn't on my note 3 (like auto sync photos to google cloud), as well as some other settings that I just turned off like AT&T Address Book, and several google sync services I have no need for. Hoping that fixes it, I'll know tomorrow!
Android System.. that is where it would be syncing photos, right? I'm thinking that must've been it.
Get a wakelock detector
Sent from my SAMSUNG-SM-N910A using XDA Free mobile app
I've noticed that is phone really really wants to have full gps on stand by at all times.
Can't wait to get that battery update. But when that happens maybe never

A background process is eating your battery. I have gotten over a full days use with 3 hours or more of screen time and still at 35%, that or you got a bad battery. This phones battery life is incredible
Since I just got my phone this morning, I will have to report my batter usage later.
However, the phone charges SUPER FAST!
I'll tell you when it doesn't charge fast, I plugged it into my S3 charger last night at 11% and it still wasn't at 100% when I woke up about 9 hours later. Yesterday I got 3 1/2 hours of screen time after starting at 70% when I actually got the phone around 5 pm. The phone was under HEAVY use (downloading updates on LTE, customizing, etc.) I'll be interested to see how it does today under mostly normal conditions.

Glad to hear you feel that way! Thank you for the glimmer of hope! I have a feeling you are very right, and that it could have also had a lot to do with the huge amount of downloading I was doing yesterday. Today should be a much more normal day of use. I'll check back in a bit.
My battery went from fully charged to 94% in a matter of minutes just using the Internet. I decreased the screen brightness and removed the sync from some apps. If I don't see an improvement before my 14 days is up this is going back.
I also realized power saving mode was not enabled. After enabling that and disabling all unnecessary sync services, I'm stoked.
Usage seems to be great now, too.
81% battery left so far today
1h30min screen on time
3h23min total
Screen 33%
Android Sys 21%
Android OS 13%
Stellar!

You shouldn't have to use power save to get good battery performance. You definitely have a bad battery
Really? It seems pretty good to me now.
Is there a wake lock detector you would be able to recommend? Looks like it needs root?
I let my battery completely drain where it cut off at 1% and let the battery charge fully. Powered it back up and made sure nothing was syncing that I didn't need and now the battery seems to be performing better then before.
My battery usage today
Was on web and Facebook most of the time, downloaded some new apps, and uploaded a video to vimeo
Battery is quite short of impressive, and my N3 charges much much faster.

Either you have fast charging turned off or something is wrong with your charger/battery. turned off my phone charged 0-100% in 79 mins.
Yeah, his phone is broken or misconfigured if it charges slower than a Note 3. I've owned both, and the note 4 charges WAY faster.
Sent from my SAMSUNG-SM-N910A
I agree it is very noticeably faster. N3 was decent already with the provided charger, but N4 charge blazes.
Kinda want to get that Qualcomm fast charge 2.0 car charger so I can charge from 12v sources. The standard usb 5v 500mA regulated charge is pitiful
I have to constantly kill Index Service. It's loading CPU up to 100%. There's a bug since at least Note II. If you have large PDF files or many files of any kind, it will never finish indexing. Some reports link it to 64GB cards, but mine does it even without the card.
