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!

First day with galaxy nexus

I have had this phone for less then 24hr and I love it. But I have been very conscious about the battery life and I feel that it drops every time I turn it on. I fully drained the 40% when it came with it in about 2 hours and today after letting it charge fully then taking it off at 100% for the rest of the night I lost 16% in about 7 hours. Since I woke up from 730-1130 I have went from 84%-50% off doing basically nothing. Edit (41% after I typed this post)
GPS-off
Wifi- off after I woke up at 7
Sync-on
Social-update once an hour
Email- once an hour

The battery needs a few charging cycles to achieve peak performance. I have a GSM nexus and the battery life has been excellent with default syncing.

After reading sfasu's post, it does make sence. I had mine for about 2 weeks...first few days the power dropped FAST. But now it has improved! I listened to music and played games while on 1hr subway ride today and it went down only a small amount....2 weeks ago it went down to 50%.

please note that the battery life performance experience differs with the CDMA and GSM version.
GSM version will get better battery life than the CDMA version due to the power hungry LTE chip.
like the other posters have said, wait a few days for the device to calibrate battery and assess battery life from then on.

The poster above makes a great point. I'd also like to add though that with my cdma version I turn LTE off and it seems to help battery life. I don't need LTE speeds while running Google nav.

If I leave my idle with the screen off and LTE ON I only lose ~ 20% over 8 hours. But if I have the screen on it seems like I lose almost 1% every minute or two.

as it's been said, if you have the LTE version, that will severely drop your battery even just email and basic sync can use massive amounts of charge on LTE.
if you have the GSM version, then most likely you just need to cycle the battery a few more times, or you have something in the background using more battery than it should.

I think at the end of the day the screen is always going to soak up more power than anything else. Any savings due to settings and updated firmware is going to be very minor.

Ya battery definitely adjusted. Getting about 24 hours a charge now.

Piss poor battery life?

I don't know what I did to this phone but my battery life has been awful. I'll admit I'm a bit of a flashoholic, but I have calmed down.
I just installed CM9 alpha 3 last night. From 8am (when I left home) I did nothing but listen to music, with some very light browsing on the train. Music for about an hour and a half, browsing barely 10 minutes on 3g. I get to class and do a fair amount of texting. Fair amount being that's basically all I did in the class. Though that was on Facebook messenger app, on wifi. About a half hour later I realize my battery is about halfway. I look at my battery, it's at 29% with about 3 hours use. I restart the phone a while later (did triangle away and rebooted to test) and I got the battery critical notification.
Now this isn't new, or exclusive to cm9. A month ago in fact, I had miui (ics) for about a week, until I noticed by the time I get to class (after hour and a half of music) my battery was already at 60% and draining. Battery is also meh on gb roms (even calkulins) even with recalibrating battery.
Is my battery just ****ed?

No, ICS battery life is crap in my experience as well thus far. I am back to gingerbread until further notice.
You can try wiping battery stats and doing a calibration by recharging with the phone powered off, taking the battery out 5 mins, then charging it till full again (still with the phone off) - some people say that helps
EDIT
"Meh" on gingerbread roms , can you be more specific? I get about 15 hours with heavy use... pushing 30 with light use on permanent wifi.
Check your battery to make sure it's 1800 milliamps instead of 1500 as well.

You should try calibrating your battery and cycling it.

Battery sucks on the ICS roms, even the leaked stock TW ICS builds.

Tried blazer 4.1 rom yet? I get amazing battery life and no tweaks needed to achieve 24+ hr cycles.
Sent from my SPH-D710 using xda premium

Battery is horrible on ICS roms, I can barely get 6 hours on a clean install, when all I'm doing is texting!! Sometimes I can literally see the percentage go down every minute.

im not sure, but whatever im doing differently has gotten me acceptable battery life
and this is with 4g turned on, 1hr of voice calls, dozens of texts and ~1 hour of video/music

I'd consider that good for ICS. I can get the numbers and on screen time on GB that your images show with a day on battery and still have 40 percent left.

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.

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.

whats your battery life like?

I got stock os with all the fancy stuff disabled.
My battery charges 1% per minute when between (0-85%) after that charging slows down.
It doesnt however fully charge it usually wont go higher than 97%.
Battery drains 1%/h in standby
5%\h listening to offline-music
Today I had 6h 5 min with 3:54 on-screen time ( starting from 93% down to 2%.

About the same for me but I can do a full charge in 45min coming from about 9%

About the same, recent CM builds are better. I'm considering the Nexus ROM
Sent from my Fire Phone using Tapatalk

At first i thought the battery life was ok, then i switched to the nexus rom for a while and came back to stuck because i wanted my camera back. There is a huge difference in battery life as far as I'm concerned. Stuck OS burns way more battery when idle but then again it has a lot more bloat :/ so it's to be expected

I get awesome battery life. On rooted stock with third party launcher with various tweaks. Way better than my desire or Moto g or Moto x or nexus 4 ever were.

Agreed, all other roms besides stock get awesome battery life. I've disabled or uninstalled as many apps as possible and the battery still drains unacceptably fast at idle. If we could get a stock rom modified to get the battery life of a custom rom that would make this phone perfect for me.

I consider the battery in mine to be working very well and use ~33.3% every two hours with the screen at full brightness and constant touching for reading. So looks like its about the same.
Standby is ~50% used in 48 hours with wifi on and background apps using the internet.
That's based on the apps I use and whatever they're doing in the background to wake the cpu, use wifi, etc.
Stock rom with the 'fancy stuff' disabled as well.
