Since I got my phone, I installed gsam battery monitor to keep track of wakes locks and etc. (At least until root comes and I can use better battery stats.)
After about a week I noticed that the kernal drains my battery more than anything. It is always above 10%. Is anyone else experiencing this? Any ideas on how to ease the pain of the drain? (haha, that rhymed. )

I have poor battery life on my desire, it barely lasts 7 hours. I have tried wiping battery stats etc, and have the screen brightness at 50%. I have read that some kernels can greatly improve battery life, is this true? If so, which would you recommend, and do I just flash it like I would a rom? I am using the latest miui.
Cheers,
Steve

They can but finding the underlying app causing the phone not to sleep would be what I'd be looking at. Remove all installed apps and add them 1 at a time and see how the battery goes

Yeah i've tried this, there's nothing draining the battery.
Not at all
Such battery drainage can only be induced by either heavy usage, or phone not being able to go to sleep.
The differences between kernels in custom roms are merely a shades since all of them are pretty much battery efficient. You won't miraculously jump from battery life of 7 hours to 30 hours. Concentrate on your apps or even better, third party Widgets.

Probably a hardware fault then - the OS on it's own with no apps installed shouldn't drain a battery that quickly. Did you also turn off the sync options to test that theory?
Personally sounds like a knackered battery/phone
If it isn't apps/widgets (they are the culprit for heavy usage) then it would prob be a faulty battery. I did a little test last month to see how much battery I could lose in 24 hours. I lost 8%. I guess it could be a baseline to start off with.
I have a desire z and I am using a recent nightly and loving it but I have one concern my battery usage stats are like these:
After Charging and letting it go standby at night:
When I woke up after 7 hours battery was %89.
Usage was: Cell standby : %46
Phone Idle : %41
Display: %7
Wi-Fi : %5
Now you may tell me it is normal to have only cell standby if I let it go standby but even if I use a lot of gps and google maps for around an hour maybe it still show a lot of cell standby. And when I am using the phone I feel like it drains the battery a lot.
Are these stats normal. I remeber on my stock rom My display was always eating the battery like %40 %50 ish now display never shows above %10 even if I use the phone a lot!
Is this because of radio? Should I try different radios? I had radio that came with downgrade of my Desire Z and than I flashed the neww Bell radio.
Please help cause I am not sure if this is normal.
Noone ? any idea?
I'm on CM7 #186 since Sunday and my battery's live is slightly higher than with stock Gingerbread.
I recommend that you install "Battery Monitor Widget". It uses a lot of RAM, but it has some pretty good statistics what's using the battery.
About the display: I think in stock the battery display stats are wrong. Mine had always 70%. On CM7 it's 7% right now after two working days and moderate news in the evening. Phone idle is 43% right now.
Probably the display usage is wrong on stock rom but i am not really sure. I will try that app you recommend thx.
So my stats arent that weird.

I've looked through the other battery life thread, but I didn't see many people posting easily comparable data so I figured i'd see if my usage was normal compared to others.
I've recently noticed that my standby current (screen off, background data on) hovers consistently in the 50-60mA range. I'm using Battery Monitor Widget from the market to obtain the data. I don't remember if I had this with stock as the battery life was great so I didn't pay much attention.
I'm currently running Skyraider, but have had the same usage issue with AOSP roms (MIUI, CM7) and it doesn't seem to matter what's installed or whether or not the radios are turned on. Standby current never goes lower than about 50mA.
Anybody else using battery monitor widget or something similar care to post your average usage? Listing whether or not you're stock or rooted and what rom you are on would also be helpful.
Thanks.
I'm going to assume that no reply's means everyone is either happy with their battery life or nobody uses a current monitoring widget.
Just wondering why my Inc2 has a ~50mA standby current and a lot of other android phones seem to be able to keep that below 10mA. Some data from another user would help pinpoint if it's just my phone or the Inc2 in general.
My stanby by drain is also pretty high compared to other phones I've tried everything I could think of to track it down with no luck. Maybe its just the inc2

I guess it's good to know i'm not the only one. It's not that my battery life is horrible, it's just that it seems like it could be so much better if the standby drain was reduced.
I feel the same way. under battery use my idle percent was 1 on my inspire. on this phone i've seen it as high as ten. no screen off profiles or disabling widgets helps. I have no rogue apps either. it must be my phone

Hello.
I was wondering if my battery life is low or not, so I want to know what your battery life is guyz.
My battery would last like 12hs with wifi always on and facebook, some music here and then and youtube. is it a normal consumption ?
There are so many variables that come into play with battery life that is nearly impossible to quantify what sort of battery life someone should be getting. Screen on time, brightness settings, radios used, reception, usage patterns, apps running in the background....tons of things that will be different from person to person. Also, the actual battery itself comes into play with how well it can hold a charge.
As long as you are happy with your battery situation, all is well. If not, perhaps look into what is using your battery. Better Battery Stats can potentially help you narrow down where things on the software end are draining your battery.

That's about what I use to get.
I went out and bought a spare battery. I'm not a fan of extended batteries so I went with a standard battery for about $10.
I also flashed a new kernel that will help on the screen brightness and underclocking.

Hi, I've got my S4 mini week ago and I was really satisfied with battery life, but suddenly yesterday my battery went crazy and right now, I get over 10% battery drain per hour, with just simple use. I didn't perform root or anything else with my phone. Please does anyone know where should be the problem? I don't wanna go to service with my phone in first week that I have it.
I've attached picture of my battery use.
Thank you for your answers..
Judging by the screenshot, the battery drain seems to be quite ok - you have made some phone calls, the screen was on for longer time as it seems.
Try to test the battery drain without using the phone.
To get more detailed information about battery usage, you can try Better Battery Stats (here on XDA http://forum.xda-developers.com/showthread.php?t=1179809 or in Play store) or Wakelock Detector (in Play store) apps.

I have the same problem. One time i killed about 20 apps and my stats looks like below
but when i restarted phone baterry problem come back. Now i don't know what i killed, but i try to find it.
PS
I have 9192 phone. (3G, wifi, gps are disable)
Get an app which offers some better statistics. I would recommend BetterBatteryStats, but since it costs two bucks you can try your luck with WakeLock Detector first (sorry, not allowed to post links). What you want to look into first is, if your phone is going into deepsleep mode when you are not using it. Wakelocks wake your phone from deepsleep and this costs battery life. Install one of the above apps (if it is BBS activate the WatchDog from Settings), reboot your phone and put it away for an hour or do this over night. Then check if there apps which keep your phone awake. Good luck.
P.S.: It seems there is a bug in Android 4+ which causes battery drain on some devices, including Samsung devices. It occurs suddenly and can be stopped by a reboot. Google: android issue 22878
The ticket is from 2011 but was recently marked as obsolete, whatever that means.
