[GUIDE] Know more about battery life on your LG G3 by having accurate readings!

Hi just sharing some experience with my battery life as it lasted me more than half a day and I'm quite glad with the results. So let me share what i did...
*Rooted my phone
*Did a nandroid backup (in case battery readings are way off)
*Installed xposed
*Downloaded Boot Manager from xposed.
*Disabled unwanted startup apps such as facebook, etc.
*Downloaded Titanium backup and disabled some bloatwares like McAfee, Email, etc.
*Downloaded Battery calibration from playstore by NeMA.
*Charged my phone to 100% and did the calibration.
*i let the phone discharge and charge it up to 100% without opening the phone.
FAQ:
1. So what does battery calibration do exactly? - Root is required. It deletes your batterystats.bin and replaces it with a fresh one. This is usually used after flashing a custom rom. I tried my luck on stock and seen the difference.
2. Do i get a bootloop if i deleted batterystats.bin? - chance is 0%. You can actually manually delete it using your root explorer then reboot. Now after reboot, you can see that a new batterystats.bin is there.
3. Does battery calibration support all android device? - probably yes.
4. Does it improve battery life? - NO. it actually gives you an accurate reading of your battery. If your battery starts to drain faster than it should, go get a new battery.
And here i got almost 16 hours of battery as i wasn't able to last a day before without 2nd charge. I was at 4G with auto mode, played clash of clans, brightness set to 50 with auto brightness on, some music for 4 hours straight, and a lil bit of Youtube. Btw I'm using stock rom 4.4.2 and so far this is the best battery experience for me. Try it and I hope this also works for most of you.

Deleting batterystats.bin does nothing you describe.
All apps concerning this matter ("calibrating") are completely useless and bogus :good:

Kinda useless on our self-calibrating charging chip... Besides, batterystats does not influence displayed percent, if we are not talking about samsung phone on 2.3 rom...

I've got an LG G3 D855 that shuts down at about 30% every time. When it shuts down it says 0%. Ive just replaced the battery (twice) after getting stuck in the endless loop restart. Could this be a problem with the batterystats.bin file? Truly stumped here and would really appreciate some help.
Thanks, D.

Android OS Wakelock killing the battery!

Hey guys,
I've been having an S6 Edge+ for a couple of days already but there seems to be an issue with the ROM. I'm getting a lot of battery drain from the "Android OS" and I'm losing up to 5% - 7% per hour in standby.... I have even re-flashed the entire ROM and factory reset two times... still the same.
I've disabled Google's Location History and Google Now but this did not help...
My previous Galaxy S6 was also running the latest ROM but there were no such problems...
Has anybody else experienced such an issue and do you have any ideas?

Check if any sync is stuck in loop, sometimes this kills battery very easily. If all else fails check with some app like GSam.

Unfortunately GSam does not produce too detailed information without Root access and it only says Android System and lists all the services that are under it...
The interesting part is that after several re-flashes with the same firmware, the wakelock disappeared...
Now I get 76% to 80% deep sleep...
Go figure... Probably some stuck sync as you mentioned...

Ah great... I also had similar issue previously with Calendar sync, couple of flashes and it went. Now happily rooted

Android OS Wakelock killing the battery! ...... solved
OK, im not too savvy with settings and systems, just sharing what i have been through. I too had a major battery drain problem on my S6 Edge+ , giving me abt 8-10hrs of use after a full charge. Even during the nights with everything off and power saving enabled i would lose abt 50-60% battery over 8 hours. ..... caused by Android OS ....... it would keep the screen awake for hours even with the screen off .... ( dont know how that worked) ..... tried a factory reset but didnt help. Then rooted the phone and downloaded wakelock detector and installed it as a system app. Installed greenify and doze ..... last night lost 4% over 11hours with wifi and 4g off and power saving enabled which is a drastic improvement. Facing one little problem that images do not get downloaded (automatically or manually) in whatsapp with wifi in use. Will use the cell for a few days and post again abt how the battery is holding up and if there is any other performance issues.

If you want to save battery, try this app:
https://play.google.com/store/apps/details?id=com.kunkunsoft.packagedisabler
It show all RAM usage of each app, you can disable any app in Bloatware (samsung default app) list to save power
This app run WITHOUT ROOT

Note 4 Fast Battery Drain

Hi,
Not sure if this is in the right section so admin please feel free to move.
Ive googled my problem and had a bit of a read but dont really get any solutions.
Ive noticed a serious battery drain since upgrading to 6.0.1 - maybe it happened on the previous version however ive just seemed to have noticed it more since i did the update.
My battery doesnt last very long. It will show 100% in the morning. If i dont use it, it can go down to about 80% within an hour or so. If i do use it then im using apps like gmail, whatsapp / sms, short phone calls, some other apps but im not on them for very long. I normally close all apps that are running in the background.
This morning it was 100%, ive used it as described above and its on 57% and its not even dinner time yet...
Ive checked the battery usage and top of the list is " Cell standby" with 48% usage showing power used is 1530mah - which is alot. The next is "my data manager" (an app to manage data usage) showing power used is 485mah (alot less!). Ive attached a screen shot.
Ive also noticed that once the battery gets to around 30% it drains even faster. I find myself using power saving mode when it gets to about 20%. It still seems to drain at a similar rate. Maybe slightly slower.
Any ideas on what i can do to recover battery time without buying a new battery. There seems to be a few topics online relating to battery drain when updating to the latest android version.
Thanks

Factory reset might help a lot.

Dont really wanna have to do a factory reset if i can help it.
I forgot to mention i also cleared the cache in boot mode

I had same battery drain issues when i updated from lollipop to Marshmallow but after doing factory reset everything is better then lollipop and doze feature in 6.0.1 works very well. I leave my phone at night about 9 hours and not drain even 2% battery and i got 5 hours scrern on time .
try factory reset+wipe cache from recovery and use atleast 3 days to doze feature work properly.if you have same drain issue then it's a bad battery.this is the only solution so far.

Battery pull?

S4-i337 battery drain via Android OS

Hi there, for the last week or so, with no new apps being downloaded prior to issue, I have noticed a significant battery drain by Android OS (39%) and inside it showed incredible Keep awake time of 16h 50m (though the phone screen is off). For reference, the screen time (25% battery usage) so far is 1h 31m. I have installed and given root access to GSam Battery Monitor (its root companion is activated too). The program indicates that Kernal (Android OS) is taking up my space but I was hoping instead it would be able to give the direct app that is eating up my battery. I have tried restarting it twice and after letting the battery run off completely and fully charging it before turning it back on.... no dice.
S4 - SGH-i337M (jfltecan/jflte)... verified root... Android 4.4.2
SlimROM-4.4.2.build.4-OFFICIAL-3650
Build number: slim_jfltecan-userdebug 4.4.2 KVT49L 3650 test-keys
Kernal: 3.4.82-KT-SGS4-gb0a91ad
Recovery is via TWRP
I know there may be suggestions to turn off GPS, WiFi, etc, etc... but I'd rather not do that due to the fact the phone life was absolutely fine w/ them on... I'd like to fix the root of the problem instead of working around it. I haven't made any changes to phone settings for a month. Reformat is a last resort but want to exhaust options prior to.
Any help appreciated, thanks.

It seems that the only way to have figured it out is by disabling individual apps and see if there is any improvement in battery life and drop in Android OS wake time and battery use.... After checking the 4th app of possibility, it seems like KiK was the culprit. Just going to remove the app as I haven't used it much. Maybe an update for the app occurred causing this to happen. One work around for those who want to keep the app that's causing the issue and minimize the battery drain, you could just go to the app's system settings and do a Force Stop and the program will be off and then turn the app back on whenever you need it and then turn it off again via Force Stop. It's a app issue, not anything you can really do about it except downgrade or uninstall the app.

Battery Drain when off

Has anyone any ideas, if I turn my x727 off the battery will drain to zero in a few hours. If I just set to airplane mode battery is good for three or four days. Accubattery shows battery in low nineties for remaining capacity. Currently using AICP pie ROM but also did this on lineage and AEX ROMs. I don't even know what to check as phone is off. Any help appreciated.

Only thing I can think of in order to discard some things are:
When did you notice this? after some modding? Have you flashed the recomended firmware for your device from the first post of AICP thread?
Then just for test:
While the device is off, connect the charger to see if the charging screen appears.
Then power on and once in AICP reboot to TWRP and from there just power off with TWRP menu, wait few hours, power on and see if there were battery drain while off.
Regards.

Thanks, it has done it for about one year, kind of thought about powering down from twrp. Have just been hitting airplane mode instead of powering down all this time. Firmware is correct. I thought something must be hanging. Appreciate the insight.

Just tried the shutdown from twrp. Battery went from 45 to 16 in one hour of shutdown. I am befuddled.

hello i have the same problem. i bought Lex722 as used one
i installed fresh Lineage OS.
when phone is off it drains in about 1-2 days down.
So i replaced the Battery with a new Battery. But... it get also down.. to i think its an hardware problem
one more thing: i charged from 0-90% . the Battery gets really hot. (Original charger). so maybe something with charging unit in the phone not ok

I have an X722 and I have a similar problem, after changing the display I have some problems like the one you mentioned, battery drain in stand by and my smartphone charging above 80% it shuts down and starts draining the battery, has anyone tried Qfil to try to solve this problem? or is it a hardware thing?
sorry if my English looks bad I'm using a translator

I think I had something hanging and the phone not really shutting itself off completely. Did a wipe when doing an update and it fixed itself.

I have similar problem too, have X722, started somewhere in summer, spring where basically discharged by 10-20% daily when not using..
I always update to latest AICP. Just replaced battery today and still seems there is a small drain, charged to 100% for the first time, 2 minutes of usage and already down by 3%.

This may or may not help. You need to track down all the hogs. These were two that caused me endless issues. I tried disabling backup by switching it off and this and that... until going full rambo on Google.
Google Backup Transport and Backup Framework wuv to run amuck even with screen off.
I finally package block them and firewall blocked them. Clearing their data, as well as Goggle Play Services* and system/residual data caches if they act up.
Now it's stopped.
>1%@hr battery drain with AOD always on.
AT&T Note 10+ Pie
*enabled as needed for gmail, gmaps, playstore.

Can I successfully disable them by just disabling their services in MyAndroidTools? (just checked and i already had them disabled)
I also have Magisk module - Universal GMS Doze.

Yeah but portions* will still run in the background just like the malware it is.
Hence the firewall and the frequent data deletes.
Maybe 10 or 11 is better behaved but it doesn't seem that way from what I'm reading... they look worse than Pie. With unrooted phones they even block more user diagnostic tools than Pie, perfect. Pretty sure my 10+ will run on Pie for its whole service life because Google dropped the ball.
Fortunately Pie is a good OS... add to that AT&T and their partner Samsung are notorious for device killing near update end cycle firmware.
Not updating is simply an act of device self preservation.
*hopefully you can pull these weeds out better than I can on an unrooted device.
Each user/device is different though, good luck
