Hi,
so far I was happy with my SM3, even under heavy use it always lastet 2 days.However, since I did not recieve the OTA update I did a factory reset of the watch like it was suggested in one of the threads here. Got the OTA update two days later. However since I did the factory reset I have serious battery drain issues. even without a connection to the fone I'm loosing up to 10% an hour, under light use I barely last a work day.
Hi,
You can see battery usage information from android wear app, setting -> watch battery
It will show you a graph and you may find which causes your battery drains.
I have a SM-T800 on CM12.1 that averages a current drain of around 60 mA during deep sleep. I also have a OnePlus One that averages around 9 mA during deep sleep.
I'm using Battery Monitor Widget Pro with the "Android mA" setting to get my readings on the SM-T800.
Obviously, there's quite a difference there. The SM-T800 draws almost 7x as much current while it's doing nothing - no screen on time.
It makes me think that there must be something I can do to reduce the current drain, especially with a rooted device. But, I haven't been able to figure out what.
Has anyone been successful getting their battery drain lower? If "yes", what have you done?
Thanks,.

Did you forget the thread you made 2 weeks ago.

Yeah, @Tinderbox (UK), but since the title was messed up I didn't think folks were looking/responding/searching to the older thread.
I think this is still something we can all benefit from, if someone has figured out a way to get our power consumption down. And if someone does respond back to this thread, other folks will be able to find it when they search now.
I use Euphoria OS and debloat it, that gives me a few weeks of standby if it's just sitting on a shelf. Ensure you delete Trebuchet (replace with Nova/Apex/etc) as it sucks a huge amount of CPU power when idle.
If you can run without GApps you'll maximize the savings.
As i said last time my T800 only used 1-2% in 16hours what ma does that work out too, the battery is 7900mah
7900mah/100 =79/16*2=9.8mah
Every time you install an app, it can make an huge difference, if it stops your tablet from sleeping.
You need to check your wakelocks to see which apps are keeping your tablet from going into deep sleep, auto check for emails, sync, alarms will cause your tablet to come out of deep sleep.
John
Thanks, @Tinderbox (UK).
As a test, I decided to wipe out my current installation, and just load the latest Nvertigo SM-T800 ROM and the very minimal nano Open GApps. I had to load a few minor things beyond that to get functional (KeePass Droid, Opera, MyBackup Pro, Wakelock Detector). I disabled all Google account sync items.
I disabled Trebuchet wake-ups, and set autostart off (Thanks, @fraser.dk)
I'm still seeing about 1% drop every 4-5 hours.
Nothing stood out from Wakelock detector. After 24 hours of the tablet sitting idle, the wakelocks were all less than 30 each.
Are you running a specific ROM or Kernel?
I am on the Stock UK v4.4.2 kitkat rom, I have never flashed though i am rooted.
If you are rooted, try the app in the link below, it link to XDA and you can download a version of cpu spy reloaded, it works great at spotting wakelocks it`s the only wakelock detector i use now.
I am running an Sony App that is supposed to stop all wakelocks, it`s in standby mode, you can whitelist apps if you like, I am not certain if it`s doing anything at the moment, you need root and exposed installed.

A 1% drop over 5-6 hours is not bad.
John.
So i have an result on the Sony Battery App, I put my Tab S into sleep mode at approx 12:30AM it was at 69% , I woke it up at 6:50pm, it was still on 69% after 17hrs.

for me i have downgraded back to stock kitkat 4.4.2, debloated, rooted and xposed installed, and use powernap, i can use the tablet all day and still have between 45% - 60% battery left depends on if i am playing games or not... i have tried so many apps and custom roms in lolipop and none of them have good battery life....
PowerNap which is the Sony app i use, only reduce battery drain in sleep mode, by stopping all wakelocks, it does not reduce the power that games or other high drain app require, so how does you battery last longer, how much power were you loosing overnight when you tablet should have been sleeping it must have been immense.

on kitkat i had no major battery drain, i just like having powernap on my device... on LP like i say even just using the tab battery would drain like 1% every min... just doing typical web use... i have tried everything to get good battery life on LP but nothing works for me at least.. but with KK i have no issues...
A lot of people say they have had no problems with lollipop, but there is an significant number that have reported problems after upgrading, I decided to stick with kitkat and await android m.
1% a minute just browsing that`s bad.

I think I'll try going back to KitKat, and see how things go.
I have been frustrated on how fast the battery drains when doing minimal tasks, like reading an ebook (about 1% drain a minute).
Downloading KitKat from Sammobile now.

Bummer.
I installed the Canadian stock KK ROM (T800XXU1ANJ6_T800XAC1ANI1_HOME.tar.md5) onto my US SM-T800, and it's boot-looping.
I thought I should be able to load the Canadian version without any problem.
Is there a way to turn the tablet off when it is bootlooping? I don't want the battery to drain while I'm downloading another ROM.
Try this to stop boot loop.

Thanks, @Tinderbox (UK)!
Out of the bootloop now, and setting up KK.
What do you do to prevent OTA updates? I have TWRP installed via the All-in-One Auto Root.
If you are rooted you will not get ota updates, if you are not freeze the updater an tab s owner did that with an app called "package disabler" it works without root but the free version keeps being removed from google play store, the full version is £2 (£1.50) just reduce.

@Tinderbox (UK) WHAT KITKAT ROM YOU ARE USING ????
stock UK kitkat rom v4.4.2, Lollipop has been out for my T800 10.5" for an couple of months, but it is full of bugs, and quite a few people have went back to kitkat.
Kitkat has been solid for me, I ran it for 164 days continually, I never rebooted or shutdown in that whole time, no problem at all.

So I updated to Marshmallow on my LG-H815, and now my battery drain is a lot higher than on 5.1.1. I'm checking GSAM and it seems like Android System (logd) is using up the most battery.
The phone is running quite warm as a result, before, at the end of the day, my phone would be on around 60%, now it gets to 20%.
I can't seem to find much about logd, but so far I've disabled WiFi scanning, and checked to make sure Activity Logs is disabled.
Does anyone know what could help to bring Marshmallow promised battery life improvements?
Cheers.
I had a battery drain because of Bluetooth. After disabling it it's gone. It's only temporary solution because I need BT to use my SW2 smartwach. So LG do your job.

First thing is to do a factory reset after you upgrade to MM, my battery was worse until I bit the bullet and reset it. Now I get 2 days use with 5hrs screen on time, most of that on GSM data.
my experience with MM
Mine just updated to 20c (EU - Latvia) and its flawless! Had some battery drain at the beginning, now after 3 restarts it runs a lot better and battery life lasted around 15% longer! If someone have issue with processes called dex2oat as they running and eating up the battery, you will need to reset your phone to factory settings, reinstall all of the apps you had on Lollipop and restart phone few times. Mine disappeared next morning. I guess they were apps still optimizing for battery! Hope it helps!
My experiences with MM are:
1) Bluetooth drains THE **** out of our devices. If you don´t need it, disable it. No idea why, but with BT off, I have over 1 hours of screen on time time more every day.
2) Disable auto-brightness. Do it. Helped me to get from 2,5 h SoT to over 3,5 h.
3) Greenify really works for me. I know we have Doze, but Greenify affects system apps...maybe thats why. Or maybe it´s just voodo, idk.
Still, battery life could be A LOT better.
Well I've just done a factory reset, will see how tomorrow goes.

Did you update from lollipop directly?

No improvement after a factory reset, may roll back to 5.1.1
In my case I did update from LL directly, battery was a disaster, disabled location services improved a lot. Found out how to do CSE installation with LG UP, reflashed the phone and disabled location services, battery is great...I end up the day with 40% with normal usage with WIFI at work.
I updated my H815p (south africa) to Marshmallow 6.0 using the LGup utility the first time I flashed I selected update only option, and I was getting unusual drain so I retried and this time opted for refurbish option which I believe is the fresh install option, and still only get 55 min screen on time. Android OS is keeping the device awake all the time. What can I try to solve this.

After half a day you decided this? Wow, most people would try it for like a whole day before throwing it in.

Factory reset, set it charge overnight, then goes to around 30% with 1 and a half hour screen on time. That's what I was getting previously. I've reverted to Lollipop.
Hi, Should i perform a hard reset or through the settings?

thank you very much sir !
great solution without root !
Since getting the update my battery performance has been terrible. Its takes hours to charge the phone and when left off charge last night i lost almost 20% with thr phone doing nothing. When i use my phone the battery can be seen draining.
I have restarted the phone a number of times. Dont really want to do a hard reset though.
I have emailed LG and shall keep you all posted.
Hi,
I joined this forum just for this issue. I was all excited about the new battery improvement with MM 6.0 although my LG G4 had excellent battery life before - thought better is always a good thing.
Until I upgraded to MM 6.0 about a week ago. I thought I was just using my phone more as it kept being at 20% by 5pm when I was never less than 75% before?
So I started doing some reading and checking the battery usage and installed Greenify.
Last night I had my phone at 100%. Unplugged for 8 hours with no usage - I was asleep...
This morning battery was at 80%???
So I checked what is using the battery. The issue is that you cannot reset these items to zero but they do seem to fluctuate so this maybe a current usage? I pulled the battery for 30 seconds and the percentages are about the same.
Google Services 15% (I suspect my location services that are enabled but they were enabled under LL 5.1 and never killed the battery).
Next is a weird one com.lge.exchange 12% (I assume the exchange server I get work email on) - have always had it before as well if that is it and have not changed the sync settings which are manual so only get mail when I call for it)
Phone idle 12% - what is phone idle taking 12% for?
Cell standby 11%.
So based on a 20% drop over eight hours with ZERO usage other than standby - my LG G4 will last about 30 hours on STANDBY. No usage - just sitting in a quiet room.
Can someone help what is now sucking my battery dry all the time?
TIA
Trevor
I have the same issue, after I did the V20D-JAN update a week ago. My SOT dropped from ~4h to less then one with "Android System" beeing on top of my battery history with 50%. I really wonder, what happened to my device.
I did a total of 5 factory resets, 2 full discharges (not hard, when your battery only lasts about 30min of continuous usage) and still, nothing changed. It even got to the point, where it discharged while on the wall adapter after a factory reset. I installed no apps, no root or nothing. Full stock after a reset and it dropped charge in no time.
Disabling location, logging, LG health and most other stock apps after a factory reset did not change a thing. "Andoid System" was at 40-50% battery usage in less then 15min after I booted the phone.
Anyone else had this, too?
First let me give you my phones state
Full stock
Was on Feb update, yesterday (after 2 days of the issue) manually flashed through android recovery to march update and bug fixes.
Not rooted.
The past 3 days my nexus 5x battery has been draining very rapidly (97% down to 32% last night), nothing has changed in the system that i've done and no apps updated aside from google docs and amazon I think. I had installed a few new apps (All4 and iPlayer)) but have since removed these to remove them from a list of culprits. Prior to this battery life was brilliant.
Currently in the process of resetting to factory to see if the issue is more deeprooted. If this fails however im not sure what else it could be besides my battery dying.

Check what drains your battery. I had simillar problem.
When I opened the battery screen i saw quite large drain from some service 10112
I was able to open the service and notice it had something to do with GPS and it basically turned the GPS on without my permision (i had gps turned off)
Then i noticed it even set the GPS to high accuracy and that caused the drain. I switched the gps setting to battery saving and the problem was fixed.
However, I still havent fixed it fully because last night it turned itself on again, and my battery dropped from 79% to 65% within hour.
I did the same thing and it stopped the drain again.
Ok thanks will see if it happens tonight after full reset, I did check battery screen but the highest on there was Google play services and even that wasn't that high (4% and some small mah figure).
I permanently leave my location on battery save and previously have had no issues.
Did you restore from a previous backup? Do you have Snapchat?
No backup as not rooted etc. No snapchat.
Just reset device and reinstalled. All seems fine over the weekend no unusual battery drain.
My T-Mobile LG G3 D851 has been running fine for 2 years. Over the past 6 months or so, the phone would not update apps unless a restart was performed. This was fine for me, as I would just restart once every few days and get the updates then.
But for the past week or two, the battery has been draining like crazy. Once I restart and the apps update, the battery drain slows down, but it still goes down much quicker than in the past. I've installed Greenify. I've studied the battery drain in Settings and it first appeared to be Google Play Services hogging up 40% of my battery, but installing Greenify seems to have nullified that. Right now, it looks like Android OS is causing the phone to lose battery.
I've also ordered another battery and am waiting for it. I'm not sure if this will help. The phone is generally warm/hot to the touch near the camera and button area (upper half).
Rooted, Xposed, stock rom with no OTA updates ever since I bought the phone in 2014, froze some stock T-Mobile apps and bloat
Can anyone help me?
