[Q] Battery advice? - Samsung Galaxy Nexus

Hey, I'm running (CDMA) CM 9 (6-18 build winner00) and Franco . Kernel nightly #194 with the 512mhz GPU. This morning I unplugged my phone and let it sit for a little and ended up with this: (attached)
Any idea? I checked BetterBatteryStats and I don't have any noticeable wake locks either.

I'm kind of confused what I'm looking at but what I think you mean is that you never touched your phone for an hour, yet your screen was on for 30 minutes? I guess something was keeping your screen on without any user input. Have you checked Settings --> Display --> sleep set to (30 seconds or whatever you want) of inactivity? Perhaps it is a misbehaving app that is causing your screen to stay on.

Oh my bad, should have clarified. With those stats and screen time, I don't know how I can already be at 82% :/

Actually... that's quite average if not just a tiny bit below average. A battery usually doesn't charge all the way to 100%, it tops off at around 95-98%, so you went down 13-16% with over half an hour of screen time and approximately an hour of normal time. 4+ hours screen time is actually considered good, which is the track that you are on (13%/30 minutes). Standby will drastically save you battery as well... which can translate to 15+ hours and 3+ hours of screen time (depends on the user). Also to take into account, the first 10-20% of the battery drains faster than the rest of it as well.

[Q] Battery Life Issue

I am having battery drainage due to the display (unlike most people who are having battery issues because of the android system). I've tried dimming down the brightness and putting the screen timeout to the lowest possible but the display still sucks up most of my battery. Can anyone help me with this ?
I think that would be normal. It's a 4.5 inch touch screen; it takes a lot of juice to be so pretty ...
Under settings - about phone - battery usage - display, what is the time on vs. % of battery usage?
I've been off the charger for 30 minutes and display use is at 76% since I've been browsing news and xda non stop.
If your screen on time is low compared to it's battery usage, it's a different story. Sounds like you've tried the usual fixes.
Well I've been off the charger since 12 last night so it would be 12 hours. But the thing is that the display usage says 51% and the actual time on for display was only 2 hours.
and also my battery drains 1% about every 30 minutes with the screen off.
2 hours of screen on time sucking 51% of the battery sounds normal to me, even across other Android phones on GB. Touch screens use lots of power.
Maybe someone else can chime in with something I'm not getting, but it seems normal to me.
This is a screenshot of my E4GT after 33 hours off the charger with normal usage. I don't play games, but I do text a lot and had a few calls as well. As you can see, the screen was on 20% of the 33 hours, meaning 6.6 hours etc etc and I still had 9% battery life at that point.
I am loving my phone!
Doesn't that 20% mean that the display used 20% of the battery power, not that it was on for 20% of the time? If you select the Display, it actually shows you how long it's been on.
I just feel like my battery should last longer than it does. I used to own the moment and that would last me three days with moderate use. ButI guess that this phone is more powerful it would make sense not to last three days. If only that would happen haha

This battery life isn't normal right? Bad drain

I cant tell if it's always been like this. Or if this actually isn't normal because I'm always concern with battery life. Im a very heavy user in the sense my phone will be on and im texting, xda, social apps i.e google +, email check every hr, and twitter.
However, i started feeling like my battery has been draining alot faster when the screen is on. I have no problem with the phone sleeping. I was experience this on Calk rom and now acs ics rom. I literally can look at my battery percentage drop 10% in like a half hour. Is this normal if screen is on the whole time? I've used better battery stats and system panel I can't find anything causing the drain. I see the suspend and events but doesn't that effect the phone sleeping?

Are you on the new modem? Looks like you have weak a signal. EG31 might help a little if your not on it already. I used the full EG31 tar right when it dropped and have been getting great battery life (it may be to early but so far so good)

not sure if its going to work but hoping it does thanks for the response still
turn your display down to under 50% you won't see a difference except outside in daylight and kill this app every time you reboot the phone hit Settings>Applications>Running services then hit DRM content > stop > ok
I get over a day on one charge.

Ok ill try the drm content stop..however my display brightness is already down at like 10%.
Also, kill the Social Hub as well, that drains the battery significantly.
You might try one of several roms available in dev. They address most of the aforementioned issues.

The biggest battery drain reason is the location by wireless network option. Make sure its unchecked. Ever since I did that, my battery life has been awesome. I get to keep my brightness high, Bluetooth on, etc...

All the basics (brightness and all that stuff) on top of the stuff you have running. The darn task killer/manager I see in the icon top left of your screenshot is a HOG on resources check the caching... You can literally **** with these phones for half a day to set it up the right way to conserve. I think wireless is hogging too but I am talking primarily about the first part of your rapid loss, the left part of the graph so to speak.

I purchased an extended battery and was still getting crappy battery life. SpareParts always FC'd on me... but last night I found Badass Battery Monitor in the market and in my opinion it's even better than SpareParts!
It helped me find that the Hotmail app was keeping my phone awake for almost an hour every day even though I had it set to download email only once a day. Removed that right away.
Plus it gives a great % readout in notification of the battery level. I think it's a fairly new app, but it really is worth checking out especially if you're having battery drain problems.
Just killing Social Hub has increased my battery life significantly. I'm at 11 hours now on battery, with 62% left. This is from last night when I unplugged the phone at 100%.

I'm on the Sydnicate Rom there isn't even no social hubb app. He has alot of the mods like noCiq and everything. My phone sleeps well its just when I start using it I can see it basically draining like 10% every half hour. I'm a heavy user I know my phone will drain fast while I'm on it I just would expect it to last 8-10 hours on heavy use.
Right NOW:
I'm at 4 hours 12 mins 22 secs at 37% left.
Display Time is 50% 2 hrs 41 mins 51s (Brightness is set all the way down)
Android OS 10%
So I'm assuming in 2 more hours my phone will die. If this is just normal for a heavy user then I guess I have to deal with it?
I was very disappointed with my Epic Touch when I first got it. I was getting a dead battery in about 6 to 8 hours no matter what I did or did not do.
Calibrating the battery seems to have fixed it.
I'm at 73% battery with 8:32 hours up time and I've made about 12 calls ranging from 2 to 10 minutes.
I've also checked voice mails, emails and other stuff.
I just charged the battery til it was full, plugged and repeated until it stayed at 10%, popped into CWM5 and cleared the battery data and then used Battery Calibration from the market (free) and it's like a got a battery upgrade!
As far as wake lock issues, I've not having any of those. I took my charger off the phone around 3:30am this morning (100% charge) and when I left for work at 6:50am, I had 98% battery still.
When I got to work it was down to 96%, I checked my email on the drive there.
I'm trying this out, wish me luck.
There doesn't seem to be any possible way to charge my battery to 100%, unplug it and not have it immediately drop to 99%.

If those screens are both from the same charge, I see nothing wrong with your phone.
you have 17% left, and you have 2.5 hours of screen on time. So you're on target to get just over 3 hours of on screeen time which is completely in the norm for these phones. AND you're over 12 hours. I don't understand what else you could ask for?
People get all caught up on total charge time, but, to be honest, it's completely IRRELEVENT.
If I dont use my phone I'll get easily over 48 hours out of the phone... Screen on time is what matters. And from a full charge, if I were to use my phone for 4 straight hours without stopping, it would be about dead. When the screen is on, you're using the phone, and the display is the biggest battery suck out there. When I do all the tricks to conserve battery, and I set it up right, I get 4 hours screen on time, which is pretty incredible with these phones.
Now, If you WANT to get better then you have right now, a few things are coming into play.
1) Your signal is weak, this will suck power no matter what more then it should, so get better signal if you want some more time out of your phone.
2) If you installed a new rom, and you didn't calibrate your battery properly, you're losing battery life.
to calibrate properly:
a) download battery callibration app from market
b) charge to 100%
c) unplug battery charger and REPLUG IN and wait for 100%
d) repeat step c a couple times
e) while plugged in hit the calibrate battery button in the app
f) unplug phone and use til dead and recharge
This will yeild you the best battery life.
3) De-Theme. Although I use a theme, every theme I've tested, for one reason or another, drains my battery faster then running the stock phone theme.
4) If you haven't done the basic battery saving things, you should do them to help yourself out. Here's a few I use.
a) Turn off background data, you only need it on to use market
b) Turn off, or set sync for all email and social apps at as long intervals as possible
c) dont use any widgets
d) download watchdog lite so you can see when apps are acting up and using extra battery
e) when you're done using your phone, open task manager, kill all apps, and clear memory
f) always leave the brightness off automatic and as low as possible
g) download SETCPU and run your phone at 800mhz, and undervolt as much as possible (50mv most all phone can take)
h) use black or dark wallpapers, on LED screens back means the pixel is off which uses less battery
G will be your biggest battery save. I've also tried using the SUPERFREEZE thing in the dev section and, besides in sleep mode, I saw no adverse effect. If you wanna kill socialhub, fine, but I dont see any noticable difference on my phone with it off.
If you do all these I promise you'll get better battery life.
Wow, I did a proper calibration today and I'm getting great results already. I've calibrated before but I never had cleared stats in CWM or did the unplug then replug charging thing.
Anyways, I after 12 hours I'm still at 35%! The longest I've ever gone before is 12.5 hours. Screen on time = 1 hour 30 min, but some of that was a battery intensive game (puzzle quest 2). Also i'm running calk's rom, so i'm sure that helped.
Thanks kdoggy, i didn't expect to see results this great.
Those are good tips too Jermzz, thanks!

Battery drain issue?

Hey guys,
so I recently purchased an International HTC One X and hsve loved it so far, but I think the battery is draining too fast.
On standby, it drained from 93% to 89-92% in 8 hrs which I suppose is good, but while using, it drops pretty quick. I wanna know how many hours or how much percentage does your battery decrease by while on standby or during use?
By the statistics I have provided, do u think there's anything wrong with my battery?
PS: I used the built in battery app, go to settings>power
Thanks, Id really appreciate it if u could help out since I'm worried if my newly expensively bought phone has something wrong with it or not, ill hit the thanks button

Battery drain
I'm currently on Leedroid' ROM and the behaviour is similar to what I had with the stock rom and looks like the folowing:
Data or WiFi on, autobrightness on, autosync off
Hangs a litle on 100% then dops abruptly from 98-97% to 80% in about 4-5 hrs with a screen time under 30'
from 70% to 30% however, the battery drain "magically" improves giving 6-8 hrs of standby including 2 hrs of screen time of which the most is used to browse the net via 3G.
At the moment my stats are: 13h 50' on baterry, 2h 15' screen time, 21% left
I got a steep drop from 31% to 21%, just as I was checking the stats for this message, but bare in mind this is the first run with Leedroid (flashed last evening) so I expect things to improve.
After 10-12 days on the stock rom I remember getting some 3-3.5 hrs of screen time within 16 - 18 hrs total before reaching 10%.
So i suggest, give the battery a little time to settle, then adjust your usage habits according to what you get (like turning autobrightness off, data off etc).
I for one am waiting for some stable kernel improvments regarding the tegra power mangement (sounds cool, have no idea what I'm talking about and I expect to get some 20-30% more screen time within the same time period (18-20hrs).
I've been running a few battery tests. Last night I wanted to totally burn out the battery so I used it down to about 5% and started a youtube movie streaming over wifi at full brightness. An hour later...... it finally died.
The companion core on this thing can really confuse you are testing standby time or music and video playback.
I want a mod for the phone where I can toggle it to use 1, 2, or 4 cores. To the OS, it looks like core0 is also the companion core.
Thanks

Thanks for the reply
so do you think there really is something wrong with my battery?
i read on a popular android website that they played a video on mx player in loops and it lasted for 6 hrs and 6 mins, which makes like 17 percent for every hour of viewing. I downloaded mx player, gonna watch a movie, and hope the battery drain is on par
The less battery doesnt bother me much, what does is that im worried that there MAY be something wrong with my battery, gonna try out for a day or 2, gonna see if my results can match urs, thanks
just hope theres nothing wrong with my battery
PS: i have everything stock, i unlocked bootloader, flash CWM5.8.x.x but returned to stock later.

So the browsing drained about 70% of the battery right? Suppose those 11 hours of sleep took even 10%, and u have 21% left, so u spent about 70% on the browsing right? Thanks
when you charge to 100% it drops down to 95% then charges back up to stop over charging, who ever it doesn't show you the % it just says 100% thats why you can lose ~5% in a few seconds when first taking it off charge.
yesterday i got 14 hours 9% left and had just a little over 4 hours screen time on leedroid 5.1.
playing games is a massive drain

Battery Fix
I had a pretty serious battery issue during my first couple days with the phone, where the battery drain was extremely fast and inconsistent, sometimes dropping 5% at a time and giving me maybe 8 hours of life total.
The issue was that the battery tracking in the phone was messed up. When you go to Settings>Power, the default setting for "Fast Boot" is on. This seems to mess up the way that battery drain is tracked. I fixed the issue by turning Fast Boot off, charging up the phone to 99% (it wouldn't reach 100, that's how bad it was messed up), then restarting it. Now, it works perfectly and easily gets me through the day with moderate/heavy usage; I watched a 30 min video streaming from youtube of wifi and lost only 7%.
The downside is now the phone takes 5 seconds longer to start up .

I did that, and streamed on youtube for 30 mins, lost like 9 percentage, is it good? or is there something with my battery?
All of your battery issue will be sorted out people..don't forget that One X is still running on GB kernel n so is transformer prime..Nvidia n HTC are working on the ICS kernel..n once they are out with it our HOX is gonna blow away everything in the Market in both performance n battery life :beer:

That's perfectly fine. Battery drain will never be perfectly consistent (perhaps your video had better graphics/resolution than mine did). Looks like your battery's OK now.

What is your idle battery life and setup with JB?

I'm noticing my idle battery drain on JB is slightly higher (but not significantly so) than it was on ICS. What is your idle battery drain % per hour on JB, and with what setup (ROM, kernel, # accounts syncing, etc.). Could this be entirely due to the "update location" checkbox in Maps (possibly for Google Now)? Any other potential causes?
The first night with Jelly Bean my phone went dead overnight (from about 51%), so I went through my settings and found that it was Google Now and/or the location updating in Maps. Probably contingent on one another. I turned Google Now off and unchecked the "Update Location" settings and the second night it only lost 4% battery in 9 hours.
Note: I also had GPS turned off during that first night so I don't know if that caused higher drain but I'm going to wait to see if it will be addressed in a future OTA before using it again.
I am actually conducting a bit of an experiment to find out more about the battery drain. Im in school so my phone spends a great deal of time on idle as I work. Yesterday I got about 22hrs of battery life with 2 hours of on screen time and some light web browsing, only sync accounts is Google. That was with stock Kernel and BAMF's JB build. This was about the same, maybe even better than my stock ICS 4.0.4. However I flashed James Bond kernel (3.1.9.9) and was pulling 1day 15hrs average with the same kind of usage (maybe enven a little heavier, didnt take screenshots unfortunately). Currently I have Franco kernel (r220 384gpu) loaded and overnight with 4g left on for 8 hours I dropped maybe 5% max.
I have no reason to go back to ICS so I wont do more testing on that front but I plan to try some kernels on the rom I am currently using.
For last night only 3% for 10 hours with wifi is on.

So idle drain used to about half a percent per hour, today during work it has been 1%+. I noticed the "Keep awake" time under Android OS is over 2 hours even though screen on time is only 40 minutes. This is likely the problem right? I heard about possible issues with Light Flow on JB but I'm not sure if that would show up under Light Flow usage or Android OS. What are some other possible causes for the keep awake time here? Specifically related to Jelly Bean.
My battery drain has remained constant over the upgrade, I am getting about 2 days of battery life on idle, about 1 day on heavy usage.
Anybody else? My idle drain is now consistently at least 1%/hr or slightly more, whereas it used to be half percent/hr. I'd like to know what is causing this increase. Should I turn off Google Now? Are there apps I should try that will tell me? My Android OS keep awake time is still almost 4 times what my screen on time is...I don't think that was the case on ICS. What are other people's keep awake vs. screen on time?
Currently I have about 1hr 10min screen time and OS keep awake time of 7hr 33min. Total time on battery is 1day 2 hours and I still have 35% It seems that the kernel included with the Vicious build does not fit with my usage habbits and will be loading the James Bond or Franco kernel I had before. I feel like they had better deep sleep and governor management for my usage.
My current usage and stat on stock: 1d 16h 30m, 48% bat, 1h58m on screen with wifi is on. it's amazing
Ok, so yesterday I installed BetterBatteryStats. My phoned was unplugged for about 17 1/2 hours, screen on time less than an hour, and the Android OS "Keep awake" time was 15 hours and BBS showed Awake time as the entire 17 1/2 hours, and no deep sleep at all. However, I checked the various other things (wakelocks, processes, etc.) and even the highest item on each list didn't show more time than 10-15 minutes.
So I rebooted, checked several hours later, and it was in deep sleep for 90% of the time. That's good to see, but the issue is the no deep sleep thing keeps happening.
What can I do at this point to figure out exactly what app or process is preventing deep sleep? I've searched around and haven't seen many suggestions beyond BetterBatteryStats, which isn't showing me any major offenders.

Anybody else? My idle drain is now consistently at least 1%/hr or slightly more, whereas it used to be half percent/hr. I'd like to know what is causing this increase. Should I turn off Google Now? Are there apps I should try that will tell me? My Android OS keep awake time is still almost 4 times what my screen on time is...I don't think that was the case on ICS. What are other people's keep awake vs. screen on time?

I was thinking the same thing as you just as I was getting ready to charge my phone and wondering why Phone Idle + Maps were a third of my usage. I had 131 hours (32% remaining) on battery with 30% idle and 3% Maps, 33% screen with 2 hours 27 minutes on, 2.5 hours awake. I didn't start noticing this change until the last Maps update and turning on Google Now location stuff. Better Battery Stats also showed an awful lot of wake-ups each time I went to look before charging.
I also didn't notice this problem with 4.0.2 before I made the jump to 4.1.1 so it will be interesting to see if our increase in idle/Maps consumption is because of our Google Apps wanting to know where we are and if other users notice the same thing when they get upgrades - be it community or carrier based.

Another battery thread

Running CM10 Wild into the Night.
If I let the phone sit without touching it, I get an average drain rate of about 10% per hour, lasting me about 10 hours on a full charge. However, the battery decides to have a field day as soon as I perform the occasional texting and web browsing.
As shown by the screenshot, culprit is the screen. However I have the brightness set way down (about 1/4 from the bottom) and the phone goes to deep sleep 70-80%. According to Gsam battery monitor, the screen uses about 60% of battery with only around 52min of on-time during the 5 hours that a full charge lasted.
Something is definitely up. When I was running stock Touchwiz, AndroidOS used to be the battery hogger. But now the screen has taken over the crown on CM10.
Screen will always use the most unless you neve use the phone. How old is your battery? Does it spin?

That sounds like you need a new battery. 52 minutes is no
Where near long enough
. or possibly with the screen on some app is running the CPU full speed
use CPU spy and leave the screen on indefinitely after unplugging it from the charger at full battery, and see if the highest CPU state is being used for the entire screen on time after you unplug it.
