Battery issue for some people - maybe found out why.. - Galaxy S I9000 General

I alrdy posted a question about this but I figured it out myself in the meantime (i think):
My phone has/had a very high battery drain and I was wondering why. So I kept watching the battery history over and over.. and yesterday I recognized that sometimes the phone doesnt seem to go into sleep mode. When you see the battery history, the "Execution" % (the thing that shows how much % of uptime the phone has been executing/running something) went up even when the phone display was turned off. This meant that some process had to be running.
So after watching the thing closer for a while I noticed that its the mediaserver process. Restarting the phone did help. But after a while the problem was back. So after some more investigation I found out that (in my case) Fruit Ninja was causing this. When I played it, afterwards the mediaserver would keep running. I tried to kill the process, both in app settings, and even in terminal mode, but without sucess. Only restarting the phone did help so far.
..
So if you having very high battery drain you could look into this. There might be other apps out that cause this too.
To see if thats the problem check battery history and note/remember the actual execution %. Then turn off display/let it lie for 5 or 10 minutes, and check the % again, if it went up this or a similar problem might cause ur drain.
--
If someone can figure out a way to restart/fix mediaserver without restarting the phone it would be awesome.
To view the process in terminal:
ps | grep media
tried killing with -15 and -9 both didnt really work, although the response was that the process was terminated/killed. So maybe there is something else wrong than the process itself.

You might be on to something.
In the last few days I have been seeing horrendous battery drainage.
I charge my phone in the evening and next morning it is at 40% left!
I also thought it must have had something to do with the phone not going to sleep.
Battery history tells me "Time without Sleep: 4d 6h", in the last 110 hours since restart!
So something is preventing it from going into sleep mode.
Thanks for sharing, I will see if I can test it a little more.

for me exactly the same,
mediaserver up and ruining in background after playing ' pocket legends', restart did help.
running on original samsung rom 2.1 jm2, just rooted.

I can confirm this problem (generated by Fruit Ninja apparently). killing the service with the terminal emulator (using root and the pid) and then restarting it seems to work, but it's not really user friendly.
Should find a way to avoid the mediaserver to loop or at least automatize the process (for example with some sort of background script that kills/restarts the mediaserver if it has 5-10%+ cpu usage for 5 minutes or more pooling every minute)
Edit: killing the process and restarting it brings it to low cpu usage, but I'm not shure the phone goes back to sleep mode as it should
Edit2: I don't really understand... I had the phone on for 2 days, then I've started fruit ninja and the mediaserver went crazy. Killed it several times and everytime I've restarted the game the problem come back (and this is all ok).
I was pretty shure the problem was in some .png in the .apk file since there are people with a similar problem caused by corrupted images or videos, so i extracted them and opened one by one: no problem at all.
Restarted the game, killed it.. and the mediaserver was ok at 0% cpu usage
I guess there is a combination of more elements here.

I tested the game, turn off, 7hrs of idle later I lost 40% battery!

The same problem here ! I need to charge my phone every night. If i leave the phone over the night it may take up to 30 % of the battery

Hoi,
My batt. drained in less than six hours, so I tried different methods to get around this. Switching 3G off and so on. But nothing helped in my case! So I went back to the store, explained the problem... The guy came with some of the usual excuses.... So finally I've dicided to buy a NEW batt. With that all my problems just went a way. I average 2 to 3 days with moderate use. Checking mail, some news,Radio for like 1 hour. About 10 min. Call time and a few other things.... So a new batt. solved my problem. Just incase a bought a spare.
But aside from this, Samsung should look into issue and handle the complaints seriously.

Overheating and battery life.

I don't know what all your experiences are, but I noticed the past few days that my epic is getting hot on the back.
I also noticed that my battery is draining more so than usual. When I got the update last week my battery life sucked, but now since this overheat thing it's gotten worse. It drops a lot even when in standby.
I do not have gps, wifi, anything else on. I am not rooted. Didn't do any battery tweaks. This is completely stock di18.
This is normal use with 3g. It's getting annoying and I'm hoping someone has an answer. Thanks!
Do you have any email accounts configured in the mail application?
This happened once or twice - I rebooted the phone and all was peachy.
Sounds like you have a rogue process wearin it out.
Yeah my phone overheated yesterday while charging....this phone has a few more steps to go before it really beats my hero...

I partly found out what the problem was, but it seems you guys are ahead of me. I had some process keeping my CPU running at 95-100% nonstop. I still haven't figured out what the process was, as now it is back to the normal 5-15%, but I'll have to keep an eye on it now.
the task manager widget turns red and it shows you what process was causing it...for me it was the xda app...a few times.
I think my problem was not backing out of WordFeud. I didn't notice anything on the task manager though. Hasn't happened since that one time.
this happens to me when i'm plugged in and using gmail. screen flickers and then shuts off. the screen-off battery indicator shows the batt. gauge and a little thermometer sign next to it indicating it's too hot.
wtf?!?! this has to be a defect. anyway, is there any official word on this? any pr from sammy/sprint?
i have read elsewhere about some epics resetting themselves a few times a day which could indicate an issue with heating (at least on a pc). so if you think it might be hardware its possible. otherwise keep doing what your doing, monitor your processes for anything thats eating it up, go to about phone > battery use > cell standby to see your time without signal. the higher this is the more battery use. also, might want to consider a startup manager to prevent the 2 DRM files (search forums) from running as this can affect batt life too
you can also use setcpu even (free on here, search it) to throttle your cpu down when it hits a certain temp.
This is very interesting... My wife and I both have this phone, she has had this happen several times after the last update (I though she was just crazy). Me on the other hand... No problem!
I need to look into this a little deeper.
The only time my epic's battery gets hot is during heavy use or gps. Gps/Nav makes it heat up like a mofo. But other than that... *knocks on wood* Its all good, no problems. As far at battery life, I am rooted and using SetCPU to turn down the processor while the screen is off, helps a ton. Not using anything other than that... was using juicedefender but then I started not getting calls or text...

One thing, I learned, that didn't help my battery was putting my phone in the locker at work. That thing must have killed my TWS and ate my battery alive.
i feel like this thread will start to die but i had a weird somewhat related issue last night. i too have had maybe 3-4 times where i woke up to my charging phone with the red LED and a screen that would not turn on, battery pull, worked fine.
however, THIS morning my phone would freeze like 30 seconds after boot EVERY time. tried a few things to no avail until I wiped, reinstalled my ROM (aosp 0.4.1) and the data from a previous backup (which was the way i got that ROM to first boot successfully according to tips in that thread).
so this worked, but i couldnt figure out why my other steps wouldnt. had to be something in the data partition of my system at the time, since changing that worked. the only thing i could think of is that app watchdog which someone mentioned to track processor usage by apps. anyone else ever experience this?
I have experienced this once when I was playing Robodefense while the phone was charging. My phone tends to get a little warm when it charges, and hot if I run something intensive while its charging. Wondering if this will be an issue when I use this phone for GPS nav while plugged into my car.

"I'm having this problem too...I didn't get any warranty for this either. Any reasons onto why this is happening...I woke up this morning and picked up my burning phone lol the temp was at 50C so I took out the battery and let it sit for 15 mins...it went down to 30C, then after not touching it for another 15..it was at 17C...very odd...what should I do, this crap is going to die within the next hour I'm worried it will fry the hard drive or something. Need help! " - I wrote this on a diff. forum a couple days ago
I dont have anything on, no wifi, gps, or any 4g (lol only if I could find it)...I even got rid of my facebook/twitter/weather updater widgets. The only thing that updates is email, and that's only if I click on it. The battery has been dying a lot faster and I charge my phone next to the window now because its like 20 degrees outside here in Chicago, so that brings down my phones temp lol....and today, my phone's battery life went from 100 to 5 percent in about three hours of barely using it...wtf?!
Also, another problem...sometimes when I lock my phone and unlock it after taking it out my pocket or something, the screen doesn't seem to respond...I keep swiping my finger over it to put in my password and it wont do anything and it only works when I slide up my phone for the horizontal view. This happens like 4 out of every 10 times I open phone.
Very embarrassing especially if your trying to get someones number down, I stopped showing off the phone now ...lol

Mind of its own - Battery issues

I have my phone setup so that I get fantastic battery life . . . sometimes. I am rooted and running EE rom with Phoenix 1.43 kernel. I can easily get 24 hours of life out of the battery sometimes, but other times it has a mind of its own.
Take today for example.
I charged the phone last night by plugging it in for 8 hours, taking it off the charger, turning the phone off, charging for another hour, turning it on and then off and then charging for another hour. NOTHING was running on the phone when I took it off the charger, as it had been rebooted several times. Tasker handled the airplane toggle, as it does every boot and autostarts disabled the DRM.
So from around 11 when I took it off the hook till around 2, I didn't use the phone at all, and I lost about 11% of battery life. Then I start to use my phone a bit, and I noticed that in spare parts, it showed the phone was running 100% of the time and was not sleeping. So I restart the phone and use it very lightly until around 8pm. From 3-8 PM I lose 4% battery life, which is perfect and what I expect to see. Then I start up Angry Birds and a couple other games until around 8:50, losing only 16% battery life, which again is awesome and acceptable. But then for some reason, after I stop using the phone and set it down from 9ish till midnight, it keeps losing battery at the same rate as when I was playing Angry Birds.
It seems to have a mind of its own. After a fresh restart and being taken off the charger, it decides not to sleep properly. Then after a restart, the sleeping problem is alleviated and the phone acts flawlessly until I begin to play Angry Birds and the battery goes into free fall mode. What gives? I really dont want to have to restart this phone as often as my Windows mobile phones, but it seems like I have to restart after being taken off the charger so that the phone can sleep, and restart after I play some battery intensive games, to reset the phone.
Also, why does the phone do this:
When its charging, it charges up to 100% and then lets it drain down slowly to 96% and then it charges it back up again, over and over and over all night. So its basically a crapshoot when you pull the phone off the charger. It could be anywhere between 96-100%. It looks like the instant it hits 100% it stops charging and lets the phone drain the battery, so its almost an impossibility to get a phone with a 100% charged battery.
I was having this same issue when I noticed I had Superuser installed in both system and data. Most of the newer kernels install it to system by default, but I must have updated it from the market also. After deleting it from system/app, the no sleep issue on every other boot went away.

Interesting. I don't see a second superuser installed in data, but what I did see in the superuser logs was that juicedefender asks for root several times every 5-10 minutes. There has to easily be a hundred logs in Superuser for juicedefender today alone. Wonder why its constantly asking for root and what effect that is having on battery life.

Try not using Juice defender and just install a app/widget that lets you shut off data yourself. See if your phone sleeps without JD.

The only problem with that is that its a pain and I will forget to do it sometimes and if I shut off data I can't get emails or anything. I have used Tasker to try and emulate juicedefender setting up schedules to toggle data, but it is MUY complicated and I didn't like it as much.
That said, I don't think its Juicedefender causing the no sleep issue. I think it has something to do with charging the phone while its on. As for why it nose dived after I played some Angry Birds, no clue. I am suspecting voice search has something to do with it though, because I accidentally launched it while playing a different game and it just took me about a dozen times tapping the END key for it to finally die without coming right back.
I hope that I do find out its Juicedefender so that I can have Tasker just restart the program when I turn my screen on or every few hours or something easy like that.
Alright, quick update. I found out what caused the rundown after playing Angry Birds. It seems that the new Fascinate music player included in the rom I am running, which I love BTW, has a service that runs as soon as it is launched and that does not end even after the app is killed.
Service:
CorePlayerService
Whenever this service is running, my phone cannot enter sleep mode. Just tested it out several times, and as soon as I kill this service my phone sleeps normally.
Now, how to figure out how to automate the killing of this service.

Warning: Do not install 2.1.4 firmware

Okay, just a warning. This firmware is a battery destroyer. Within 11 minutes my battery has dropped 10% and I have no running background processes and I'm not doing anything with the unit. Just checking the screen once in a while. I've actually watched it go down 1% in a minute.
I'm telling you...if you have not installed this update...don't do it!
Too late for me.. already updated. I'll keep an eye on my battery level and let you know if I notice it go down faster than normal.
I just unpluged from the charger. It is at 100%.. I'll let you know where it is in 1 hour. I'll turn on display to stay on to simulate being used and then let it set.
Edit: Okay after 10 minutes.. still at 100% screen always on.. that was with whatever programs load into the background after boot.. I haven't killed any apps. I now have launched my Pykl3 Radar app to increase cpu from 300Mhz to 1000Mhz.. it refreshes the radar screen every 5 minutes.. we'll see how the battery does with the processor working harder.
I'm not noticing any difference really... Same battery life as before(I think, I haven't done any formal battery life tests or anything)
Seems fine for me too, but I'll go ahead and do this test.
Edit1: After 30 minutes it is still at 100%.
Edit2: After 35 minutes it has gone down to 99%
Edit3: After 60 minutes it has gone down to 96%
Edit4: After 90 minutes it has gone down to 90%
Edit5: After 2 hours it has gone down to 82%
Edit6: After 2.5 hours it has gone down to 76%
Edit7: After 3 hours it has gone down to 67%
Edit8: After 3.5 hour it has gone down to 61%
Edit9: After 4 hours it has gone down to 55%
Edit10: After 4.5 hours it has gone down to 50%
Edit11: After 5 hours it has gone down to 46%
Edit12: After 5.5 hours it has gone down to 44%
Edit13: After 6 hours it has gone down to 40%
So this averages out to a discharge rate of 10%/hr
This test was done with the screen fully on the whole time. Mostly running at full 1000Mhz and with wifi on and downloading data every 5 or so minutes.
If I let it run down to 20%, I would probably get about 8 hours which is within the specs of the Archos 101.
I was pushing the device harder than average and I believe in normal use I could get more than 10 hours.
So I conclude the battery problems aren't related to the latest firmware release 2.1.04.
Yeah, looks like you might just have a problem with your device. Have you tried reformatting and reinstall?
After about 4 hours of usage (mostly Wordfeud) with Softlocker active (keeps device awake when screen is off) I still have 82%.

Saying that your battery is depleting at 1% per minute is useless information given that many electronic devices can sometimes drop by 20% in 1 second
Please only evalute battery usage by observing how much time it takes to fully discharge.

Yesterday I updated to 2.1.4 and really have not noticed any battery drainage. No issue from my side.
Updating last night on Archos 70 8GB, after fully charged all night and playing net for 20 minutes continuously, battery drops to 99%. No sign of drainage too.
don't see any issue on battery drainage on my Archos 70IT either =)
It is interesting, but in this thread I appear to be the odd freak out and no one is having any issue except me...yet in the other 2.1.4 thread, a lot of people are experiencing this battery problem...not sure why that is, but the problem is there and it is real even if it is hit or miss on people experiencing it.
Yep, it's real. I put in a service ticket. I wiped and reloaded my a70 today, but it was still drawing over 800 ma listening to Pandora. I only had about 30% left on the battery, and I wanted to completely discharge it. It's stone dead and on the charge right now. I'll find out early if it helped. 3am start tomorrow. Goodnight.
(first post ) I just installed firmware 2.1.4 yesterday, and haven't noticed any difference in battery life. Although, I have noticed that 3d games obliterate my battery life now, where they just ate it before.
Wiped, reloaded, completely discharged, and charged over night. Down 20% the first hour.

Mine is still around 10% drop every hour I have wifi on for net surfing. Mine just upgraded from 2.1.2, just for information.
don't see any issue on battery drainage on my Archos 101 IT either
One thing I am noticing is that is seems more sensitive to cranking up the processor to somewhere between 600Mhz and 1Ghz at various times. Before it wasn't as sensitive and often would stay in the 300-600 range for me. This change may be why people have noticed "increased performance/less lag?"
That might be part of the drain issue or something else.
I think the point is that it is hit or miss out there. Some people get the glitch and some don't. Regardless, Archos needs to address the problem.
Ok, now this is interesting. Just to try something different, I reformatted my tablet this time and installed 2.1.3, then restored everything with Titanium. I seemed to be holding up much better. After an hour it had barely dropped. To put it to the test I drove home from work with bt gps and google maps via tether. All tolled, in 2 hours it dropped about 10%. I thought I had it fixed. Then I realized I hadn't rebooted after restoring with Titanium, so it was still rooted. I rebooted it and the wheels came off. It dropped over 10% in about 20 minutes. I ran the root app again and it leveled right off. It's down to 10% now so I have to charge it before I can experiment more, but maybe someone else can try and see if they see the same thing.
Maybe root has something to do with it.. I've never rooted and don't have a problem.. I wonder if the only people having problems are the ones that rooted.. although it sounds backwards in your case.

I was wondering the same thing. It also seems to have to do with wifi, because with it off it draws almost nothing. The exploit has something to do with the wifi, so who knows.

FIX and INVESTIGATION: Android OS (battery drain) problem on Gingerbread

CASE CLOSED!!! Please read bottom part or flash stock GB 2.3.4!
I have posted this already on another thread (almost word for word) but I just really want you guys know and not panic about this problem and avoid going through difficult fixes like deleting system apps, recalibrating battery or even resetting your phone.
Since JVK was released, many observed that Android OS sometimes get hungry and devours battery. For some reason it is triggered to go berserk. Others say that the main culprit is the Auto update app. But other apps like Google Maps, Latitude and even just in a place where there is very low network signal or Wifi reception could also trigger this problem.
Now, I have a very simple solution: Turn off device, remove battery for a minute, put it back then turn it ON. Yes it is just that simple, REBOOT YOUR DEVICE.
Yeah after you turn on your device Android OS is still on the top of the list with high percentage but I believe it is just as it is because it previously consumed a lot of battery. All you have to do is observe again for an hour if your battery is dropping again, look into the graph and see if it is still steeping to the bottom. If it is dropping like Mt Everest, do the procedure above again.
If not, you will observe that after a couple of hours Android OS's percentage is getting low. Problem is fixed, (temporarily though).
Why go through deleting apps, recalibrate battery etc when you could just turn off your device for a minute?
I have experienced it a lot of times already (one of the first users who upgraded to JVK) but it doesn't bother me anymore. Turning off then on your device is very simple ain't it?
I highly advise that you do not touch anything on the sensitive part of your phone as there is no known single root of this problem. Just like I told you, many situations or apps could trigger Android OS to go berserk. Until there is no definite solution to this problem, I suggest you do the above procedure and save yourself from going through the pain of removing system apps, battery calibration or even hard reset.
By the way my battery usually lasts 3-4 days unless I made Android OS angry again.
INVESTIGATION
INVESTIGATION CLOSED!!! The culprit is caught. But the fix is not so simple. Only Samsung and genius devs (apparently the fix requires closed source modification) could fix this. If the problem occurs on your device, just do the temporary fix above. Please do not try to mess with your device for now.It is now fixed in XXJVP 2.3.4!
Click HERE and read the bottom part for more details.
All this is due to Tatsuya who pointed us to the right direction. A big thanks to him for helping us in this investigation. CASE CLOSED

Ok thanks for the credits.
This previous link I gave explains how you can use watchdog to alert you when this bug triggers, so you know when to reboot your phone to stop this leakage (if you really want to stay on gingerbread until a fix is made by Samsung).

Guys if you want to help out please please please dial this *#*#4636#*#* and check "Usage Statistics" and let us know the top 3 items on the list! (highly suggested by {Angel}).
Below are some of the possible culprits currently pointed out by some users (I will update the list based from your feedback):
1. Software Update service
2. Google Maps
3. Latitude
4. Low network signal
5. Very low WIFI reception
6. Auto updates in Market
If this helps, a simple thanks is enough

Those of you with high drain, you can also check battery history through *#*#4636#*#* and see what you have under other usage 'running' and see if your phone as not been sleeping lately. I get this occasionaly with froyo and I suspect many people do also. A reboot fixes it for me, after that my battery usage is superb, but it's annoying as hell.

jbdroid said:
Yes just like I said in the first post, this is just a temporary fix. But I think users should just do this rather than touch anything on their phone unless they really know the source of the problem.
That is why I suggested that they report what could be the possible triggers, like apps or situations, that make Android OS to awake and gobble up the battery. If we could just pinpoint those triggers maybe we can now figure out the root of the problem. Your fix of removing a system app, the auto update app, is not even the single source of the problem. We just do not know if that app is an essential app or not. Sooner or later you will have that problem again.
I am not saying we should just sit and wait. All I am saying is if you are a plain user and you do not know the exact root of the problem, then just do what I suggested. But if you are a dev and is exploring the root of the problem, then do as you like and we will be most thankful if you find out the answer.
People are mislead about what works and what is not. I just want to help.

I once saw that the battery drain from 95% to 9% after one night, and the android os used most of it. I rebooted my phone, and the problem has gone away, since. Happy with Gingerbread!

Did what you suggested and pulled the battery at 30% waited 5 minutes and put it back in.... 1hr later it was at 35% (WTF!) and 30min later it was at 38% (WTF!)
im assuming its recalibrating?
Not necessarily. Maybe the battery meter is anticipating the fast consumption rate of Android OS that is why when it got fixed, the meter is able to readjust the readings based from the current consumption rate of your phone. Good to know it helped
Maybe use the 'forbidden' task killer? Works for me... Maybe im imagening it but works.
Btw my battery goes quickly down after getting below 25%. My battery not calibrated? Should i.calibrate it? I have this program to do it but am afraid that calibration goes wrong. (example what if my battery is 95% and will calibrate to 100. What if.i charge my battery higher than this.. Will it show 104%? Or will android stop working for it cannot be displayed in the notificationbar.
Using cm7.
Sent from my HTC Desire using XDA App
You do not have to recalibrate. Cm7 has a known issue about battery. I think you cannot charge past 94 or 95 percent and battery usage is a bit terrible. Please refer to cm7 thread for possible fixes, (the last time I checked their thread, they say it is probably kernel related).
Just turning off, pulling the battery and turning on does do a lot for me! i went from 10% per hour to only 1%! great thnx!
Hi,
About battery drain in gb, once fixed the wifi sleep policy issue ( by setting it to "never") u shouldn't have batt drain, but i've installed green power ( juice defender do the work too i think) to get some wifi management possibility back and it improuved my batt life.
But never the less, my battery won't last more than one day of hard usage ( being hanged on xda all day long, for instance ;-)
Sent from my GT-I9000 using XDA App
Guys, just turn off the task killer, it helped in my case. looks like its not working well on ginger
Rebooting works just temporarily.
It will come back the next day or so.
This is not a solution at all tbh.
Yes just like I said in the first post, this is just a temporary fix. But I think users should just do this rather than touch anything on their phone unless they really know the source of the problem.
That is why I suggested that they report what could be the possible triggers, like apps or situations, that make Android OS to awake and gobble up the battery. If we could just pinpoint those triggers maybe we can now figure out the root of the problem. Your fix of removing a system app, the auto update app, is not even the single source of the problem. We just do not know if that app is an essential app or not. Sooner or later you will have that problem again.
I am not saying we should just sit and wait. All I am saying is if you are a plain user and you do not know the exact root of the problem, then just do what I suggested. But if you are a dev and is exploring the root of the problem, then do as you like and we will be most thankful if you find out the answer.
People are mislead about what works and what is not. I just want to help
Guys, on Gingerbread I've had battery drain two times:
1. Had about 14% drain in 3 hours all of a sudden, without doing anything at all. Just started going down for some reason.
2. This morning, saw about 40% drain in 7 hours..
And, both time I solved it by Clearing Memory from the Task Manager.. Went back to normal 2-3% drain per 6-7 hours after that..
So this might also be a solution. Go to Task Manager, RAM tab, and Clear Memory..
i'm on ginger also and my battery acts weird. 2 days ago i charged my phone over night while it was closed. the battery holds for 15 hours with massive use.
last night i did it again, but today it went from 98% to 80% in about an hour !
this is really weird.

Did you manage to check first what is running on your device by looking into Battery Usage settings? I think you have a case of rogue application running in the background.
If you have not rebooted yet could you please attach a screenshot of the battery usage list and graph? In that way we might possibly identify the app running prior to the clearing of memory. Thanks!

[Q] Battery drain issue

Hi,
I got my second android phone (LG G2 obviously) this christmas, and I haven't had time to properly use it (I don't have a micro SIM yet). I noticed that my battery is going empty pretty fast, although I heard this phone has a amazing battery. My friend got this phone too and he told he's been on one charge for about 36 hours with constant wi-fi connection, app downloading, playing games etc. so I figured something's off. I charged the device before going to bed and when I woke up (10 hrs later) battery was on 85% (only 2 MINUTES of screen time!!!!) and I had no apps running on the backround, no nothing. So now I'm thinking is there some easy fix for this or should I return it and get a replacement? Also something weird I noticed yesterday was that even though I don't have a SIM card yet, but 16% of the battery was used by the phone application. I did some screenshots of battery usage today and yesterday too if anyone's interested.
There are literally dozens of similar threads... suggest you start searching.
And I literally have gone through 90% of them so I decided to start a new thead. Do you (or someone) think that a factory reset could help? And the next question might sound stupid, but if I do a factory reset then does the warranty remain? Better safe than sorry I guess
I just played 4 minuts of hill climb racing and lost 3% of my battery, this is not normal. Does anyone even have a solution for this? All I see on other threads is questions and questions, but I don't see anyone saying "That worked and my battery life is normal now"
It's normal if screen is bright. Especially if carrier bloat is still there. Post screens, all you have, and what carrier. The phone could have been sick in a search state.
I don't think my phone is tied to any carrier, it was bought from just a regular electronics shop, but frankly I did a facory reset and didn't realize that all my screenshots will be gone too. Do you really think it's normal that 10 hrs of idling causes 15% battery loss? And it has the stock LG apps (safety care, life square, cell broadcast etc.). What do you mean by "The phone could have been sick in a search state."? My screen brightness is on 70%.
It's normal with bloat in it. They all have bloat stock. 70 is high and can eat at the battery pretty good. I mean it could have software glitched and was struck searching for activation behind the scenes. Use Wake Lock Detector and see what is keeping it awake.
This, almost 20% drop was caused by downloading 3 apps (facebook, facebook messenger and twitter), updating ~10 apps (all done via wi-fi) and rearranging my home screen.
Steamer86, are you sure? My friend told me that he has been 36 hrs on one charge without changing any settings and just downloading apps, playing games and testing the phone.
Your idle is great at that point in time. Facebook is a battery killer. That's a lot of activity with 70% brightness all the time. It's 17% and medium higher side usage and an hour+ of screen time. What are you expecting? At this rate with 70% constant screen and Wi-Fi pushing pretty good you would get almost 6 hours OST. That isn't bad bud.

I hope you are right, but for helping and giving advice I'm going to hit that 'thanks' button
This night i lost 18% of my battery and my phone was almost all the time on deep sleep.
But i did notice something weird, battery usage shows that Android OS is using up most of my battery and when I press on it and then hit the back button then the Android OS changes to something called surfaceflinger for a millisecond (check the screenshots)

Can you try putting your phone in airplane mode and then turn on Wi-Fi? If you aren't using a cell carrier than there's no need to keep that on.
See how this works in increasing battery life for you.
