I am not seeing exact issue how much android OS usng,
looking to your screenshot, display is just 6%, means hardly you have utilised your device. it was mostly in screenoff state. Ok when you dont use your device, but OS is running in background so just OS but nothing else have drain it.
Now another thing looking to image i can say in 9hr your battery dropped 50%
it means > 5% / hr, that actually i count the measure.
In idle state it shud be 2-3 % with 3G n Data sync On. So here it is more.
anyway once let it drain completely then recharge it fully n count drain %/hr.
I am using few stuff, e.g
Autostart - just kill the app you dont using
Phoneweaver - It autometically controls my data connection e.g. just after 15min to my sleeping time, it gets turnoff my data, n swithon b4 few min i wakeup.
SetCPU - I set profile to use CPU <500 in screenoff state.

My batt seems to last longer on kl7.

Your is idle. it seem 3%/hr even using screen quite good time.

My sisters Note had same crazy issue with Android OS eating battery. Tried many things to find the culprit but only thing that fixed it was full wipe and reinstall ROM. No issues now.

il calibrate battery and see hwz it working

I have a very long time use with this firmware and very happy with the update.
I just disabled all automatic synch and the samsung apps notification and things like this.
3g is always enabled and some hours a day wifi is also enabled

Don't know if it will work for you but I had the same problem. Believe it or not a simple hard reboot, solved the issue. Was identical to mine using Android OS over 70% while screen was at 15%. Programs added and deleted were still running around in the OS until that reboot(I'm guessing). Let me know if that works.

seems better. i did a complete battery drain and recharged from 0 battery. now after 5 hours after complete recharge, im at 84%. 2 push emails..full time wifi connectivity, facebook/twitter/socialhub sync always on. 5 min phone call. and thats it.i think its better.

For those who do not realize it yet, having Facebook, Twitter, Gmail, etc syncing every minute takes a lot of power. You cannot expect the phone to be doing this for 12 hours straight.
If you have a lot of battery ussage with screen off, try to disable account synchronization and see what happens then.
You need to evaluate if you need to see every social network update on the instant, or you carry extra batteries with you, or you are able to find a place to charge every few hours.
What you cannot expect are miracles.

Hang on.i have all sync enabled...wifi always on .stil look at my battery life..its decent

Hmm, something has definitely changed for me.
Up until recently I was getting two days use out of a charge with wifi, gps & 3g enabled syncing 2 gmail, 1 yahoo account plus twitter and google reader stuff. Last couple of days Android OS has gone nuts and I'm getting similar readings in terms of usage to those quoted in this thread. This morning I've drained 20% in an hour with a bit of internet use.
Only thing I have changed is updating a few apps and I've put the thing in one of those silicon protection cases but that can't be the reason(can it??!!).

[Q] Battery Problems - falling from 70 to 0 %

Hello,
i have a bad problem with my LG starting from day one when i bought it. I tried many things now, to no avail.
The problem is that sometimes my battery falls from high percent value to 0 just in one second. then the mobile goes out and i have to charge it, even it was nearly full some minutes ago.
Another problem is a warm mobile in standby mode when i have mobile inet active, and battery wont last longer than 4 hours. With WIFI it doesnt get warm but starts to decerase RAM until the mobile is unusable (timeouts, freezes, ect)
So there are 3 problems, i think related together somehow:
1. sudden Akku drainage, falling from high percent value to zero
2. fast akku drainage with mobile inet on, doesnt fall from #to zero, but get used up very fast
3. Unusable mobile due to RAM issues when WIFI activated.
Here are following some pics and a Log attached from Android Stats. Here you can see starting at 9.34 the bettery recalculations, in very short timeframes.
Can someone see any issues from the log what could be the problem?
The situation was like this: I recharged yesterday evening, and turned mobile inet on. Then i went to sleep. In the morning i saw that i had no connection to google servers (icons white instead on green) but i saw the battery was only drained 2% over night so i thought not bad.
I reactivated internet (mobile) in hope to get conn to google servers. Well, i got it but in same time the battery got drained from 98% to just 40% in one second. Since then the mobile stays warm. I have auto sync deactivated.

I forgot:
Android 2.3.4 original, rooted but nothing changed on firmware/rom/baseband/anything

So i inserted screens now.

you have some kind of background application that doesnt let your phone enter deep sleep mode to lower cpu frequency and conserve battery (phone is awake when screen is not on, you can see the activity in the pictures). you should check what app is using most of the CPU time, it might not be code optimized and might be sucking too much of the battery.
also, it might help resetting the battery stats, search a bit and find some info on that (short version, charge it to 100%, let it for another hour plugged in, go in CM, delete battery stats, restart).
worst case scenario, your battery is busted and a replacement might be needed. hope that helps.

andrei.je said:
just a hint : most battery consumption can be checked in the battery stats, on the activity graph : awake vs screen on - if awake and screen on are not synced in the activity graph (should have same lines) then you have a problem. meaning when your phone has its screen off it should go into deep sleep mode (lower cpu frequency) but if you the phone is awake while screen is off, you have an application installed that won't let your phone sleep and just keeps using the cpu and sucking the battery.
this is mostly applied to standby battery life, if you are playing a game/watching a movie, doesn't really matter screen is on, cpu/gpu is sucking the battery.
my worst battery life while i had the O2X was about 16h, but that's with normal phone use (no games - you can have a psp for that, no music - you can have an ipod for that), mostly emails, browsing, IMs, calls/texts all day long also best battery life was 2d 10h (mostly on standby)

Thanks for also answering my post on the other topic.
It may be that theres an app that keep our phone from sleep, but even with this app, when i dont turn on wifi or mobile internet, the mobile runs 6 days straight. This is no joke, offline it could hold 6 days, i have a screen of where it looses 8% in 28 hours. And as you can see on my screen, it happens from one second to the other.
I already changed the phone the third time now, even with very few installed apps, this remains. I had it first time on day one when bought th mobile. Since then in all 3 mobiles maybe 15 times.
Anyway, it bothered me, but not as much as that the phone went nearly unusable with internet active. Always at 50 mb ram. So it was basically an offline only phone. In my 2 tests, both 5 days without internet, the mobile neither went slow, nor went off, nor lost battry, nor anything. Very fast LG OS. Until internet...
Anyway, now i installed Chuck Norris CM /MIUI ROM, lets see what happens. Until now its so smooth and soft, it feels like a complete other mobile. Also with wifi active... but i cannot say anything until tomorrow.
I tested already a lot of System Analyzer apps but theres really not much to see. Nothing seem to use much battery in whole. At least nothing that explains a loss of 70% in 5 seconds.
I posted a log here, thats the best thing to see i guess, but i cannot really read it well :-(
Anyway, your help is appreciated

I think the problem is caused by the battery stat file. Avoiding the techinical causes you should only charge the phone untill 100% and using battery calibration (you can donwload it for free from market) calibrate the battery! Hope to be helpful ^_*

[Q] Weird "battery drain" when lightly using the phone

Hello !
I just bought my P880 two days ago and everything is great except one thing: battery drain. It is not occouring in background when phone is in Deep sleep, it doesn't lose charge while it's sleeping, but when I just unlock it/start using it, it just starts draining.
I have rooted it, and unrooted using SuperSU. The thing is I haven't experienced that kind of drain yesterday, it was working fine except drain caused by bad signal (badly inserted SIM).
Usage by Android System is at 50% over 5 hours, Screen is at 9%. Awake graphs are the same as Screen on graphs- no wakelocks.
I have these apps installed:
Prey Anti Theft
Skype (not running)
Adobe Reader
SoundHound
Disco Light
QR Droid
Sygic (not running)
X-plore
SwiftKey 3 keyboard
WiFi, GPS, Data, everything turned off except mobile signal
Running Internation version with Android 4.0.3, Kernel 2.6.39.4-00001-g0f9182c
Mobile network type is EDGE:2 with mobile signal -70dBm
I'm first time android user and this is my first problem so I tried to include as much info as possible.
Thanks in advance

I see 2 mayor issues, first is the android deft app, it may be running and trying to sync but bcz the data is off it will try to connect foreva.
Also, edge is (in other words) ROAMING and this forces the antenna to use more power to get signal from another provider, it get worst if you have a phone with sim card.

Thanks for pointing that out, but I have disabled every sync and I have set phone to 2G mode only, the reason is that UMTS signal was low and was draining battery even more.
I am only losing sharge when just doing random things on phone, even if that means only adding/removing widgets/apps on main screen with WiFi off.

Then you must try the Deodexed version of v10f, removing the bloatware with the script in the same thread.
The issue may be some lg apps that are running in the background so doing this will have 6 hours in standby time with 100% still, like me (if I turn all radios off ).

I have just woken up, while sleeping (9h) phone was awake for about 50%, no wakelocks but there were 30 alarms from Android/Google maps ans 29 alarms from com.google.android.gsf
Hope this helps.
I may try custom ROMs if nothing else works.
While typing this message I have lost 7%.

Similar state here as the OP. Got the phone two days ago.
All is good, it rooted OK, Directory Bind works fine, phone runs like hell (about 10 times faster than my old Galaxy S) BUT it drains battery like a genuine power guzzler.
Ok I get that according to the performance you get, it comes with an accordingly high power draw, so I don't ***** about it, I just want to know if this is normal. I mean I played 2 hours and 15 minutes of Sprinkle and the battery died, starting from a full charge. Screen was set at 50%.
GPS is off, Bluetooth is off, no 3G mobile network and screen is at 50% brightness as I said. There's an NFC icon on the notification bar next to the battery icon, which I am not sure if it should be there.
Here are a couple of shots from the battery section of the phone and from Battery monitor widget if these help.

Please note that as the OP said, the phone consumes nearly nothing when idling. Firmware is 10f.
PS I am not trying to hijack the OP's thread. I just noticed the same behavior and I'd like some help on the same matter, as well as to contribute in whatever way I can. If the OP is offended somehow, I will gladly start a new thread.

@psolord No, not offended at all. I'm glad you posted actually.
My phone has encountered 20 more Alarms, wake ups since I left it standing:
com.google.android.apps.maps Wakeups: 50
com.google.android.gsf Wakeups: 45
You can see pictures below, the drop on the second picture happened when I was writing me previous post from P880.
- I am also rooted again (after factory restore)
- I have reenabled 3G networks but the signal is only at about 50%.
Any additional info please ?

Ok buddy, so we can keep discussing it here together.
For the matter at hand, I see the same behavior, when I unlock the screen, it's like I have opened a whole in the battery.
It dropped from 85% to 65% just from downloading a new map (500MB, 20min download on a slow wifi) from Sygic downloader. I mean this can't be right, right?
I also checked cpu spy and it reports the system 75% at deep idle, 15% at 51Mhz and the rest are 0% to 1% up to 1500Mhz. So if the cpu has so little operation, what on earth is draining the battery?
I wonder if we could be looking at a bad battery batch.
Is there an app that reports exactly what activity consumes power and how much?

Indeed, the hole in the battery.
I even restored to factory from recovery mode since I screwed up the root, so it was just stock, but guess what, nothing has changed :crying:
I really hope this can get fixed, else I'll get a replacement.
I hope someone from this forum with more experience can help :/

I think I am onto something.
Can you please check how is the phone doing if you disable everything under location and services?

I am going to try this, I am also talking to LG Support right now. WIll let you know when I get more information.

I disabled everything, and I didn't see pretty much any improvement. LG Support suggested me to return the phone.
Pretty much draining the battery atm so I can charge it back to 100% and use something like Battery Calibration. Maybe it can change something.

Yeah indeed I was onto nothing. Nothing changed for me either.
Playing 30mins of a 720P resulted my battery dropping from 62% to 50%. I also used the gps for the first time with Sygic (Jesus even the GPS is lightning fast) and the battery went from 50% to 30% for a 20 minute ride. It seems that my phone cannot give me more than 2 hours of use. That's just silly.
BTW do you or anybody, know of an app that can show battery usage per app?

Stock application ?
Also you can use Better Battery Stats to see if there are any wakelocks or anything is waking up the phone etc.

What is happening right now is rather strange, I disabled screen turning off (trying to drain battery to 1%/2%) looking at stock battery app, it seems to be stuck at 21% and it's not changing.

The stock application does not do so much analysis, but the batterystats you used above seems more like it.
I am getting panicked and I miss some stuff haha. Ok lets cool.
It makes me sad that we don't get any input from the community. Something like "yeah this is normal, live with it" or "your phone is faulty, take it back to the shop for a replacement" or something.

Agreed, ANY, ANY kind of input would be appreciated, but I guess we are getting none.
I am going to fully charge it today, do some stuff and report back tommorow. Also anyone, please do post any suggestion you may have.

Maybe this has to do something with the built in power saver. Maybe it kicks in when the battery drops to the 20s and stops whatever is draining it.
I am thinking trying some battery saver to see if it does the same thing but from the beginning of the full charge.

Actually I have disabled it when it asked me if it should turn on. So I guess nothing to do with that.

I am going to backup now, fully unroot and somehow get it to pure stock. Than I'm probably going to exchange the phone in case battery life doesn't change.

Am I the only one with poor battery life?

So seeing that development is dead on this phone, I'm stuck with the latest stock ROM as the other custom ROMs cameras won't work or have issues.
Are others having bad battery life on v7.4.2 or is it just me? I've tried location service disable apps/scripts and battery saving apps but it doesn't seem to help.
I would like to roll back to the older versions of the stock ROM but then it has security issues (thanks BLU /s). Is sitting on the latest stock ROM the only option out there that functions well (apart from battery life)?

well you dont have to stay on 7.4.2, you can go to v17 and compare battery levels.

Is your phone rooted and running Xposed Framework? I've tried both 7.4.2 and v17. In both cases, battery life was fine, until I installed Xposed. After that, I also started seeing close to 50% battery drops overnight.

I just installed v17, its a little better than before. Yeah I've tried 7.4.2 with and without xposed and I still had the same amount of drain.

I have the same issue
I'm having the same issue with my R1 HD, I think the battery usage is normal during the day but the problem is it drains overnight, I disable the wifi and data and turn off sound notifications when I go to bed. When I wake up I find the battery drained 15 - 20% over those hours.
I had the blu life pure mini before this phone and barely drained 1% overnight with those same settings, I also have the smart energy saving on but I don't think is doing anything.
I just got this phone 3 days ago and I really like it (it's much better than the life pure mini) except for the battery life issue. The phone came with v7.4.2 out of the box and yesterday I just got an official update to v8.4 but I haven't installed it yet 'cause I read somewhere that some people started having issues with this phone after receiving an update, although I don't think is this one because this is from may 5th 2017 and I think that thread was from last year.
Have you found a way to solve this and have you tried this update already? Is it safe? I don't know what to do because the phone is under warranty for 10 days (I bought it from a reseller) so if I can't find a way to fix this I could maybe consider return it and get my money back, although I prefer not to because where I live its pretty hard to get your hands on a phone like this at a decent price.
I wanted to upload an image of the battery stats but I just recharged it so maybe later, here is one of the update available.

If you want to be able to root phone do not take that official update.
Battery life , for me has been good

Thanks for replying
I'm not an advanced user so I'm not looking to root my phone unless it fixes the battery issue. Unless this behavior is normal with this phone, draining battery while idle, because even with this the battery still last through the day. Its just that it didn't happen with my previous phone so I think there is a problem.
I wanted to know if there is a chance installing the official update will fix this and if anybody has had issues with the v8.4 because otherwise my phone is working fine.
I'm very new to this so any help I can get will be greatly appreciated.

Hi, I think I'm onto something with the issue, last night I tried again before I went to bed, turned of wifi, data, silenced notifications and turned on battery saver. Woke up 8 hours later to see the battery had drained 16%.
So I went over every detail of the battery stats and found that my phone is always awake, day and night. Something is preventing the phone from going into sleep mode and I don't know what it is. Only apps I've installed are twitter, instagram, whatsapp, UC browser, TY kids, duolingo, panda mobile security and an online shopping app. All the amazon apps are disabled and I turned off the automatic updates from the playstore.
Googling about this I found some people who had the same issue had fixed it by cleaning the cache an rebooting, I did this (with all apps cache) but it didn't work.
I'm going to install a battery monitor app to see if I can find something else, this thing is driving me crazy. Here are some screen captures of this morning.

Question High battery usage? Even when I'm sleeping?

The device is new, has only 2 weeks of use and I've updated it to MiUi 12.5.6 (RKLEUXM). My use is very moderate, some videos, social network just for conversations and only wi-fi connection. After the update, I noticed high battery usage even when I'm sleeping with all connections turned off. Obviously there is some battery thief, but it only appears in the graph as "smartphone services", this is not normal. Any idea?
I can even feel the phone a little warm around the cameras when I'm using it for basic stuff.

Try battery guru's app...

It's seem a 12.5 MIUI problem for all Xiaomi note 10 series

Something(s) are running in the background.
Try putting into Safe mode at night to rule out 3rd party apps.
Track down the culprits and deal with each on a case by case basis.

I have this device since August 27th, after setting it up, I started optimizing it, restricted background use for a lot of apps, well, everything that could be disabled or restricted, I only gave free pass to apps I consider important, but, the reults were really bad, 17% of overnight drain! Long story short, the optimization must be done very carefully, trying to stop all kind of things might prove negative, by trial and error, I now get a good battery life, now it barely consumes 1% in 8-9 hrs idling at night, aod off, wifi on, gps on, so, try to optimize your device carefully

I have this device since August 27th, after setting it up, I started optimizing it, restricted background use for a lot of apps, well, everything that could be disabled or restricted, I only gave free pass to apps I consider important, but, the reults were really bad, 17% of overnight drain!

Hi,
Did you single out what was the culrpit. I have disabled every non essential app, tried this solution: https://forum.xda-developers.com/t/improving-battery-life-on-miui-12.4139913/
But nothing helps. It only shows that android system is drawing power.
I will be glad if you could point what you made to fix your phone

If there is any Firewall that can log with the newer "secure" OS's you can use that to help pinpoint the rogue apk(s).
With Pie I use Karma Firewall but it's logging feature doesn't starting with 10.

After doing everything I could think of, the AOD seems to be the culprit, even thoug I really like it, when disabling it, overnight battery consumption lowered to 1% in a 7 hrs period

Thank you for the fast reply. I already had it disabled, but with no positive result.
Thank you, nonetheless.

Is tap on an option?

No, to achieve this low bat comsuption, I disabled miui optimizations, then, the option for aod is on or off, no more settings, I really like the aod, but the drain while idling drives me nuts... I painfully miss my galaxy note 10+.....

Meh, I hear that. It's to the point I got a second new 10+ while they're still available. They are the last of the stock devices running on Q.
I won't touch 11 or 12. Funny thing is it doesn't run like an outdated dinosaur.
Been a real bad year for Android...
