Horrible Battery Life

It would seem that after I installed the AT&T update to dumb down thr search on my phone, my battery life has been terrible. Yesterday it was down to about 30% after only 4 hours of light use with the processes "Android OS" and "Cell Standby" taking up the most battery. I can't even get through the day with this phone. Some help would be much appreciated.

After any update, give it a couple days to level out. Until then, just carry an extra charger and plug in when you can.

The update was installed at least a week ago.

In that case, backup everything and do a factory reset when you have a fully charged battery.

Alright I'll give it a shot. I needed to do that anyway as my clipboard no longer works and consistently crashes. :/

I did a factory reset a few weeks ago and that solved it for me.

Do you have any specific methods for backing up a phone that isn't rooted? I've got nova backed up, but I would like to make sure everything else is too.

Are you receiving push email? that was the major drainer for me. apparently the android email app has a bug.
Regarding clipboard...delete everything in data/clipboard; force close the 'test service' app and then restart your phone

The best method would be to use titanium backup but since your not rooted I don't know what options you have except to use the google backup but that ain't to good since its only app data.

Hi all,
Since getting the phone from day one, I really never had a problem with the battery. Lately however, I've noticed a significant drain in battery over night. I tested the drain a few times over several nights, and even put my phone into "airplane" mode to help save battery.
Below are my results from going to sleep at 1:30am with 100% battery power and in airplane mode and waking up at 9:30am the next morning. I get a 12% decrease in battery over night for doing nothing over the course of 8 hours.
The only thing I've noticed differently is that Chrome is starting to use battery which is odd because I rarely use Chrome to begin with.
Any ideas to help this? What should I do?

Yeah I've noticed a huge jump in Android System usage since I flashed the UCLG1 update.
Currently
18h 27min on current charge
screen on 1h 22min
Android system = 51%

DudeWatsThat, thanks I'm going to give it a try and see if uninstalling Chrome changes anything. It just boggles my mind that in airplane mode over night it would drain the battery 12%

i second that problem about Chrome. I think it is a bug regarding the builtin flash code. my battery was great until i installed Chrome then it got really bad. I uninstalled Chrome and my battery life jumped up big time. huge different. too bad i really like Chrome but no go right now

Not sure if it's the same issue, but I had some problems with battery life in Chrome until I disabled Tilt Scrolling under Developer Options in the Chrome menu.

my battery life is great even after the update

Terrible battery life (H815, 6.0 Marshmellow)

Hi all,
I've had my LG G4 since September, and it's been a good phone. However, more so recently, the battery life has been terrible. When Doze decides to work on my phone the battery life is average, but it rarely seems to work. I use over 60% battery in 5 or 6 hours, and that's with most of the time the phone screen being off.
For example, tonight I went to see the new Star Wars film. Using that as a guide, my phone screen was off for about ~3 hours during that time. However, see attached, the battery is just being drained. There aren't any particular apps that I see using 90% battery or whatever - in fact, using a battery app, it looks like phone radio is using an incredible amount.
i.imgur.com/MCQ6Yz0.png
i.imgur.com/ziZEoEz.png
i.imgur.com/a8J9ufZ.png
Any tips for increasing the battery life? I don't see myself as an over user, but I often come out of an 8 hour work shift with just 20% left, and that's with mild web browsing every now and then, and maybe 20 minutes of YouTube video.
I'm thinking about doing a full restore on weekend after backing up my texts, or even ordering a new battery, but I don't feel this should be necessary.
My screen brightness is always 30% or lower. I don't know if this would have damaged the battery, but I use an Aukey quick charger.

-since how many days are using marshmallow ??
-What version ?? V20B or V20A ?
-Did you do a full factory reset after upgrading to MM?

Thanks for replying.
I've been using it for 16 days now.
I updated though LG Bridge, and software info says V20a-EUR-XX
I've not done a factory reset, no. Will that help? All my photos, music and contacts are on Google's servers so I would just need to back up SMS and a list of apps.

Thanks. It looks like my SMS are already saved to my SD card, so hopefully they will work straight away.
I really hope a reset fixes it, as I heard such great things about the LG G4 battery (with people posting it can last 24 hours or more!), and this is very disappointing. I'm off this weekend, so I will do it then.
If anybody else has any fixes as well, I would love to hear them if this doesn't work! The phone is great so far... aside from this.

Sent from my LG-H815 using Tapatalk

you have a rogue app or something, there is nothing wrong with Marshmallow 20B (or 20A for that matter) and battery life. I get insane battery life on this phone, often 22 - 30 hours of fairly heavy use.
Now granted, my phone is rooted, bootloader unlocked, running stock 20B and I have installed a couple of apps to optimize it such as AdAway, LBE security, and KinScreen, but still, you have a misbehaving app most likely that needs to be kicked off your phone!

Is there a way of finding which app? Nothing stands out. I've just taken another screenshot (disabling uploads Google Photos didn't fix it)-should screen off be using this much battery?

A reset is definitly in order tomorrow

sure, start with turning on Developer mode by hitting Build Number in rapid succession a bunch of times in Settings ---> About Phone ---->Software Info
then look in the new Developers Options section of Settings and look at Running Services & processes - you can also download an app for this such as Elixir 2
another good diagnostic tool is heat - heat and battery life are proportional, if your phone runs cool, it will get long battery life, if you pick it up and it is warm around the power/volume buttons, then something is amiss - you have a runaway app or process
download a tool like CPU Temp from the Play store and see what the CPU temp is when the phone is idle or you are doing something light like reading an article - it should be in the 78 - 89° F. range (25 - 32° C.) If the phone is not in this temp range, then something is amiss! - Also keep in mind that the main battery drain on the phone in normal operation is the display - keep auto-brightness on, and keep the display off when it is not needed! - also turn off stuff you are not using, such as Bluetooth, NFC, etc.

I did a factory reset as suggested above, and I think it fixed it. I didn't restore my LG backup as I figured that that'd restore the problem, so went through and downloaded apps again. I then left it on overnight.
After 6 hours it was still at 100% on Wifi, which is great! I then used the phone for ~2 hours (apparently pretty heavily) which actually dropped it to 58% - whoops. I then stopped using it again but this time without wifi, and it didn't keep at the same % - it seemed to drop 10% in about 2 hours. The only things I'd changed since then was install Skype (which I might delete if that's the issue), and had it on mobile data.
imgur.com/n58dP1D
Could mobile data REALLY make that much of a difference? I think I'll leave it unplugged again tonight and not on wifi, and see what it does. This is an issue though if it is mobile, as I'm often not connected to a network.

Seems like mobile radio active bug, I have the same problem. While mobile data is active, my battery drains with the screen off. I have this issue since v20a and no - factory reset doesnt help at all...

[MM] Got Poor Battery Life? No Deep Sleep - Possible reasons, and possible fix inside

Like a lot of people I found myself with battery woes on the G4, at first my battery was comparable to my G3, if not a little bit better but over time, and certainly since MM was released, my battery life was quite frankly awful.
Long Story
I was losing power rapidly, even when I was barely touching the phone - so I finally decided to look into it. After carefully monitoring apps, wakelocks etc nothing looked out of place, everything was working normally until I installed my old faithful app - SetCPU, this is a nice basic app that just shows what your CPU has clocked too and how long it spent there in a given timescale and one thing alarmed me greatly. I was getting less than one minute of deep sleep in every 60 minutes the phone was running - now if I had been using the phone for 58 minutes of that hour I would expect this, only I hadn't!
I did more testing, and more testing and more testing but the results were the same, the phone barely entered deep sleep, and when it did it didn't stay there very long.
Now as I said, using all the other apps, and android stats, nothing looked particularly out of place and after a few days of trying everything under the sun to fix the problem I decided to go nuclear. I wiped the phone, installed no third party apps but setcpu and began testing. I left the phone for a period of 10 minutes to see what the deep sleep value was (looking for it to be somewhere between 80 and 100% of time, which it was!) and it seemed to be back to normal, working fine. So then I started to install my core apps, one by one running the same 10 minute test between each one, idea being eventually I would hit whatever app it was that caused me problems.
So I installed upwards of 30 apps, and everything was still fine, in 10 minutes of not using my phone I was getting around 9 minutes of deep sleep, which is what you would expect.
And then came facebook, now I know there are lots of reports of facebook being a bad app blah blah blah, but I have never seen facebook react like this before, and I don't know if it was marshmallow or a mixture of marshmallow and LG - but when facebook is installed my phone stopped sleeping again, at first it wasn't a huge change, but was noticeable it dropped to deep sleeping at about the 40% mark so I had 4 minutes deep sleep in my 10 minute test - force closing facebook made no difference, I tested it again and again, rebooted and again - same results.
I then installed facebook messenger, and my deep sleep dropped again, to about 20%.
I then uninstalled messenger - no change.
I then rebooted - back to 40%
I then removed facebook - no change
I then rebooted - back to 80+ %.
TLDR: The "Solution"
Now for some of you this won't be a solution as you will claim you need the apps, but there are third party alternatives out there that work pretty well without causing this issue.
Facebook (and facebook messenger) on stock MM builds (at least on the G4) causes the phone to hardly ever enter "deep sleep", this means it is always running a CPU clock, albeit the lowest setting, but it consumes far more power than it needs too especially when the phone is not in use.
After removing them my phone is now sleeping fine and my battery life is back to being very good - lost 4% in the last 8 hours (albeit idle, I was asleep), which is much better than losing 4% an hour that I was before facebook was removed.
Go give it a try, install setcpu, reset the timer close go back to your home screen then leave your phone for 10 minutes then check your deep sleep values, then try it after removing facebook (and rebooting).
Let me know how you get on.

Can you do those tests again after disabling the Marshmallow battery optimizing for Facebook app ?

I was having these issues too after upgrading to MM. My battery life was appalling and Facebook was keeping the phone awake for hours at a time. I simply did a full factory reset, and then restored my phone from the most recent backup. My battery life is now excellent, even with Facebook and Messenger installed

There was a wakelock introduced with the new version of facebook about a week ago not sure if it is still relevant. It goes by the name of bugreporting service. Something like that. The same goes with FB messenger. I got pissed off with the official app because of this and got Metal instead

I don't run Facebook (never have) or any messaging other than Hangouts and battery is always great (2-3 days). If you don't need it...uninstall it.
Kindle app was always a great one for running constantly in the background for no reason. So I bought an actual Kindle and didn't use the app.

I totally agree with the OP, I started having the exact issues after I updated to the latest facebook and messenger apps and my phone was entering deep sleep at all. I removed them last night and its much much better now.

My girlfriend's g3 with mm gets this message lots of time

Until a few weeks ago, the Facebook app had a setting where you could choose the sync frequency and I was able to set mine to every 4 hours.
This setting appears to have disappeared now. Could this be the problem?

Nope. It's not the solution. I uninstalled Facebook but am barely getting 2+ hours of screen-on time on v20b.
A Redditor mentioned that some process called 'logd' is eating up resources and killing battery life. I used Terminal Emulator to verify it.
Sent from my LG-H815 using Tapatalk

logd is a separate issue that no one has quite worked out what is causing it - it is to do with error reporting, either from LG or Google apps.

That redditor here. Logd isn't actually logging anything when its CPU usage hits 16% (the problem). You can verify by running logcat in adb shell while watching cpu usage in terminal emulator on phone.
I removed logd by renaming the binary, it's over doubled by SOT from 1-2h to 4+h. As this is my first post on xda I can't link the thread I made on reddit about it -- but you'll find it on /r/lgg4 on the first page ("PSA: How to fix 6.0 / marshmallow logd battery drain (TWRP/root)")

Android system battery drain

Hi there everybody
I've got a samsung a50 and have been seeing android system draining battery for 2 weeks
I've done factory reset and even flashed the whole firmware
But the issue is not gone
Disabled backup
Disabled sync
App preview messages
Cleared cache
Wiped data and cache google play services
What should i do?

Does anyone know why this happens? Currently on 21 percent of charge and android system consumed 18 percent. Is it normal?

It might be normal and it might be not, if your phone mostly idle and you are not doing anything on it there always has to be something to use the battery. And since you are not using it obviously Android system and other services running in background will have high percentage, but it doesnt mean it's abnormal. If you would use it heavily the percentage would be probably like 5-10%.
So it really depends what u have been doing on a phone and how long it has been idling. For example if you just leave it idle for few days and never use or turn on the screen it could be like 50% or more and it would be absolutely normal, u see what i mean?

I understand that but i have been using my phone and it has been idle a little time so i guessed there might be a problem.
Another thing is my phone is now showing learning usage patterns in battery stats because i reseted it a few days ago. Could it have anything to do with this drain?

OK
So I checked my friend's device and he has got 19 percents for androud system. I think because the screen is removed in android 10 so it counts as screen, too.

Alright i managed to FIX this
Just i put my phone in charge overnight and it got fixed. I think it is because android system optimizes apps at that time. Now android system 0 PERCENT

Because its the stats since last full charge > 100% charge = 0% because its not off the batt.
If its apps that are draining the batt i think the best thing to do is reflash stock and go from there, if you've installed apps that you no longer use for example.
Turning on batt saving things, like auto screen brightness, make sure location/wifi is off when not in use, just try to limit how much power the system needs to function is always good practice.

Question Very absurd heating issued not fixed + battery drains fast

I've had this issue ever since I restored whatsapp backups, deleted everything regarding it. Now the phone heats up noticeably with NORMAL usage, and the battery drains way faster than normally. I have done a few factory resets, cleared cache then finally flashed stock rom with odin, using nand erase option.
But the issue still persists.?! Anybody more technical than me? Been through the whole internet searching about this issue and no avail, and visited service center 2 times where they claim it is an app when clearly it's not.

What does it say for your battery usage? Settings->Battery and device care->Battery->(tap on graph)
Also you said you've done some factory resets - it can take a few days for the adaptive battery usage to optimize itself after a reset.

Yes, I installed whatsapp way back in march and this caused the problem to arise. Haven't touched it ever since.

Obviously TikTok using a lot of battery because I've been using it a lot. Installed or not, heating still occurs when using other apps. Neither is it microG, that has been using battery today unrelated to the draining issues.
And regards to the factory reset, they were done way back in march as well. I did wait until the optimization to sort itself out but nothing ever seemed to change. I had done a reflash through odin as well, making sure the storage gets completely wiped out.
The apps aren't at fault though. Before I had installed whatsapp, these apps you currently see did not have such massive draining or heating issues until installing wa. Neither did the issue go away after factory reseting or flashing the stock rom. All of this happens in safe mode too, I am not sure where to even begin with.

Ah ok, I see. Yes, that's more than enough time since your reset for the adaptive battery to figure things out.
How much is the drain overnight when you're sleeping?
Are you mainly on wifi or cell data? How strong are they for you?
Another thing you can try is dark mode and see if that helps at all as our screens use less power when showing black. I don't know how much of an effect that actually has though.
Also, if you haven't already, set your screen to 60Hz instead of 120Hz.

Overnight drain is nonexistent. And I am typically on wifi when at home, outdoors using data. Both have full bars so I am sure it's not them.
Been on 60Hz the whole time, I dislike 120Hz
I've had this same problem on my previous S7 where it was more severe due to the exynos chip. I had a spare S7 edge not used by me, so I installed whatsapp and restored the backup, and the same issue I described began. That phone ran cool without lag, now suffering the same fate as my A52s. I flashed the stock rom on the edge as well and it didn't seem to fix the issue either.

Sorry. I forgot to mention I had uninstalled whatsapp back in march, so the issue should be gone but it still persists.

You don't need to be so aggressive to me. I know what I am here for and I am trying to get help after trying to fix this by going to the service center where they claim false stuff, and whatever I posted earlier. Read what I posted, TikTok is not causing it neither is any app causing it.

Please read what I wrote above. Not tryying to start an argument here but sounds like you are trying to.
It does not matter if TikTok is installed or not. The same issue persists nevertheless and I already mentioned WhatsApp was not installed. Everything I mentioned above was tested by myself...
TikTok obviously is using a lot of battery because it has been on for a long time. Same thing, does not matter if it's installed the same heating and battery drain issue will occur in other apps. (Normal usage, not gaming or doing anything that stresses the phone)
What I am trying to gain here is advice to fix it, not asking for blaming on apps or useless advice because you never read my post.

This post is similar to what I am experiencing at the moment but for a different reason. Going to the service center isn't really an option anymore because they do not believe me and make up false reasons for this problem, and I am not a very confrontational person either.

I'm not a huge fan of these types of apps but one might point you in the right direction here - try and install something like AccuBattery and let it go for a few days. See what it says for battery usage.
It's been a while but I think there's an additional setting in the app (AccuBattery) that will enable the app to get more details, make sure you do that (was an ADB command if I recall).

Absolutely, I will install it and let it run for a few days then report the results back here.

Did you try enrolling to Whatsapp's beta program or sideload the latest beta from apkmirror and compare the battery drain between the two versions (Stable vs Beta)?
