About a week ago, I noticed my EVO was rapidly discharging its battery. In an attempt to find the culprit, I bought the SystemPanel App from the market and enabled CPU usage tracking. My phone returned to normal after a restart, so i just let the tracking keep running. Today, I again noticed my battery draining extremely fast when I got into work. I went into SystemPanel, and looked at the usage...
At whopping 42% of my CPU usage was allocated to the android "suspend" system app. It's global average for the past week was only 1.2% before this morning. Obviously, this app is doing something in the background and killing my battery. Does anyone here have any idea what may be going on?

Had my 900 about a week now, and in the first few days the battery life was looking good, lasting nearly two days with lots of texts, emailing, a few pictures taken and lots of talk time.
Then a couple of days ago it suddenly got worse. Started losing about 4% per hour. I charged it fully last night and then this morning nine hours later there was only 60% remaining.
I decided to try and find out what was happening. Found the diagnostics app and the battery drain was showing around 164mA. I don't have anything running that could be using so much power, so I wondered if I was suddenly getting a poor 3G signal and the phone was using a lot of power trying to receive it. So I put it into flight mode. Still around 164mA.
Finally I powered the phone off and then back on. Now it srttled down to around 95mA.
So what was running that was using so much power, that got switched off when the phone powered off? Could it be the GPS? I did fire up Nokia Drive and Nokia Maps the other day to play around with them. Could it be that the phone forgets to turn the GPS off when the apps that use it aren't running?

Not sure forgets is the right answer, but you may want to look at the Background tasks and see what is running when it shouldn't.
I know when I add a new app or 2...sometimes I get myself in a position where the battery drain becomes excessive. I usually just unistall the app. You've probably read a few of the battery threads here. If not, take a look. Lots of good conversation about ...well....lots of things....
For me, the biggest drain is Wordament....and its ads....I'll wipe out my battery in an hour playing that thing....
Just finished a series of tests for Background Tasks in my L900 (full article on Mobility Digest). 8 Background Tasks running burns 0.5% per hour, or 8% in a 16 hour day. Tasks included: USA Today, Fox News, Weather Channel, Urban Dictionary, Mehdoh, Network Dashboard, Clever-To-Do and Battery Meter (homebrew app that actually runs every 10 minutes vs. 30 minutes, or longer).
Except for short spikes, my phone always hovers in the 95 to 125 mA range. Data signal is still the biggest battery demon while phone is asleep. Screen while phone is awake.

Overnight my phone seems to have used less than 1% per hour, that's with wifi on but not connected to any network. Perhaps I'll see what it does with wifi off.
I'd still like to know what it was that was draining the battery until yesterday when I power cycled it. I only had the App highlighter app and the Weather Channel app running in background, and I've since disabled the App Highlighter. But they weren't using 4% of the juice per hour. I didn't have bluetooth on.
I guess if anyone is seeing a high battery drain the simple answer is to try power cycling your phone first and see if that stops it.

Cool! I'd love to see a wifi vs cellular data battery benchmark.
Well that would be hard for background activities as WiFi goes to sleep at power off.
I did try to use LTE only for a couple days, but AT&T did not start reporting my daily data usage on my monthly anniversary data. I wanted to see how much data I was using over a typical week with LTE only. On can tell you in those two days, LTE was burning 20-30% (13% per hour on WiFi / 17-18% per hour over LTE) more power per hour when the screen was on and I was browsing or using Board Express. A more comprehensive teat will follow though.

The above somewhat proves how cellular data can often be a big battery drain comparable to abundant wifi at home or other common places. Looking forward to ur tests.
Well the battery drain problem came back yesterday.
The phone has done pretty well however, with very light use (one short call, a few texts, checking FB, checking the weather and not much else) the battery is at 24% after 48 hours. Overnight it went through about 8% in nine hours.
However, yesterday evening I noticed that the battery was losing 4% - 5% per hour again. By yesterday morning it was at 70% after 24 hours. After another 9 hours it was down to 43%. That's having made no calls, only a couple of texts, and very little else. At 9.30pm I checked the diagnostics app and battery drain was over 200mA. There was no obvious reason why it would be so high. So I powered the phone off and back on again, and sure enough, battery drain settled back down to between 90 and 110 mA, and as I said, overnight the battery lost less than 1% charge per hour.
The only background task I have enabled is the Weather Channel app. I'm going to let the battery run right down, recharge it, uninstall this app, and then see if I can repeat this pattern (if people will hold off from calling me!) If it's not this app then there must be something else, something in the firmware that goes haywire after a certain time and starts using lots of power.
I note that some people have observed that the battery starts to drain quicker after a while. I'd be interested to know if anyone can repeat the same pattern I'm seeing.
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.
I haven't been able to root my last few phones so I wasn't able to really use Greenify recently (i mean I know I could use it in non-root mode, but I never cared for that and found that to be kind of buggy)...
With all the battery improvements supposedly implemented as Android has continued to evolve, do you think that Greenify still offers any benefits?
My standby drain is not so good -
According to EXKM My idle drain is somewhere around 3-4%/hour.
According to BBS, so far today out of 5 hours 30 min on battery, I have drained 5.2%/hour, down 28% in total, with almost 3 hours of deep sleep (54%), 1 hour 23 min of screen on (25%), and 1 hour 5 min awake (w Screen off) (20%). The 1 hour 5 min awake seems high to me - I did listen to 15 minutes of music so that would explain 15 minutes of it.
I checked out my partial wakelocks and the highest is ImsSenderRxr.
According to Battery Usage in settings #1 is Screen at 1 hour 23 minutes (that's good it is first), #2 is Google Play Services which has used about half the same amount of battery as the screen, #3 is Ambient Display which has used almost as much as play services.
I'm going to try adding Greenify and see if that does anything beneficial, but figured I would ask the community to see what your mileage has been like with Greenify more recently since it has been awhile since I've used it.
Honestly, I haven't found much of a need for Greenify, aggressive doze, or wakelock blocking apps on 8.0 and above. It might be beneficial to Greenify battery hungry social media apps (especially those related to Facebook), but then you end up with Greenify running constantly in the background. Plus it requests usage permissions, enabling it as a device admin, etc.
Do you have Adaptive Battery enabled? There is a thread in the general section where a few users have reported that their battery life improved after disabling it.
I came here wondering the same. I had Greenify installed for a while but im not sure its really doing much anymore. I just took the lastest OTA update and im gonna roll without Greenify to see if there's a difference. Ill report back in a few days.
I know it's the wrong phone. But I have just bought a Pixel 3a and am introducing myself to its battery usage. I use Greenify on my Galaxy S7 running superman rom. I forgot to reinstall it last time I reinstalled things and I reckon it makes between 20% and 30% improvement.

My idle drain using EX is usually around 2%. What is your charging behavior... overnight and leave with 100% in the morning? I leave mine on the Pixel stand all night. If you are keeping it in your bedroom off-charger, use flip-to-shhh. You should have done that with BBS. If you didn't run BBS again overnight. 100% charged, hot off the charger and flip it upside down. This is just for a proper overnight battery drain test. Second, I would install Accubattery. It is NOT a battery drain app, but rather will eventually zero in on your remaining battery capacity compared with new. It uses several full charging sessions from say above 20% all the way to 100%. After a few full charging sessions it will give you solid information the condition of your battery. Just ruling the battery out here. If Accubattery confirms your battery capacity is well over 90% then you may want to do a fresh install. Sometimes that is the only thing that is going to return the good idle battery drain. Just my .02 cents. Take it for what it's worth. For reference, my battery capacity started at 106% new and is now at 94%. Cheers!
My phone is a non rooted AT&T branded phone. I was checking the battery details and I saw that 86% of the battery was being used by apps. I looked at the app list. There are 2 games on there that I played early in the day. I only played each for about 10 minutes each. Each of them has used 23% of the battery. When I drill down on the app it says VideoOn:5 hours and 34 minutes. This is despite the fact that I closed all apps and force stopped those two. Anybody know what is going on? The monitoring app is GSam Pro
I have Nexus 5X and as I said, according to CPU-Z the procesor is at max capacity without a break. Its making the phone super hot and it drains battery in few hours on stand by. It started randomly without me doing anything to the phone. I tried factory reset (with partition wipe) and uninstall and disable everything I could, but it didnt help. When I activate plane mode it get little bit better, but not so much. It will just jump around 600-1440 MHz and drain battery at similar speed. GSam battery drainage says:
20% takes Kernel
14% UI
14% android system
9% Play Store
4% Google
4% system audioserver
4% Play Services
Thanks for help, I have run out of ideas.
