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.
hi guys first of all my gnote 2 is unlocked but i could not find a page for it.....so iv had this phone for about 3 weeks battery life was all well it used to give me about 20 hours on medium use....but last night i charged it to 100 percent and woke up next morning to find that the battery is completely empty.now its constantly draining battery even in idle mode i do not know what the problem is....i will list my results from the battery manager after a full charge.
its been running for seven and a half hours *mostly idle* and it is on 38 percent now.
android system 30 percent
android os 14 percent
screen 12 percent
device idle 7 percent
standby 6 percent
nearby devices 5 percent
exchange services 4 percent
media server 4 percent
media 4 percent
phone 3 percent.
keep in mind that my brightness was set to auto and wifi was off 3g/4g do not exist in my country.

please help and yes my charger makes a strange noise and also gets warm when i plug it in the wall socket and my phones back just beneath the camera also gets warm when it goes down below 10 percent charge and sometimes while on charge.
I'm at 58% with 8hr 7m on my battery, 27% screen, 22% android system, 12% android OS, 9% maps, 4% media server, rest <2%.
Overall, it blows away every other android phone I've ever owned.
you should be in the international version threads. this is for sprint.
since 3g/4g dun exist from where you are at , did u change the settings for gsm? if u leave it at default it will always be searching for 3g/4g which by alot of means drain alot of battery
[Q] Why are you posting in the wrong sub-forum?
This area is for the Sprint version, which hasn't even been out for a week...
I owned the galaxy S9 (dual sim - 128gb - exynos) since july, my battery doesn't last a whole day, all I get is 4-4.5 hours of SOT. I installed phone info for samsung from play store and checked the battery status, it says that battery health is 91.37%.
And my phone is warm most of the time, not extremely hot, just a little bit. Is it normal? Or my phone has a problem?

Same as mine, feel warm all the time, even not using it. 3hours+ SOT per full charge. Bought it on end of June 2018. After 100 cycles phone info shows 86.53%.

Don't worry about that, I don't think it can be accurate, mine says 84.97% after 54 cycles, and I'm fairly sure I remember it saying it was only about 90% when it was new, so I'd add 10% onto that %
Will wiping system cache help to decrease heat and improve battery life?
Check for any apps that may be constantly functioning in the background, streaming apps that are not closed, etc. GSam is a good app for monitoring this.
Recently, I am not charging my phone like I was doing before, I mean sometimes I recharge it to 100% when it's at 60% for example, or sometimes I let it drop to 10% or lower. Because of university needs...
But I'm noticing a very bad battery life that it lasts me about 16 hours with 2-3 hours of SOT (I only use whatsapp and open some documents at university).
And my phones gets hot sometimes like I said before.
And sometimes I unplug it and after 2 mins it drops from 100% to 98%. The battery drains too quickly! What's the problem here? (I also notice a higher % for android system usage, like 13% or 16% for example)
PS : I tried wiping cache and I saw some apps running in the background and putted them on "always sleeping apps" except of social media apps. But they still run, I can see this in RAM usage. So don't know what to do.

Thanks bro! But I am asking why I need to do all this stuff to make a flagship phone last me the whole day, my friend's s9 battery lasts the whole day with 6 hours of SOT without disabling apps, or optimizing them. And without putting a dark theme...
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!
