Hello XDA,
Been noticing bad battery performance on my device, only to find out that the problem might not be the battery itself.
Here are 2 screenshots that easily show the problem imgur.com/a/DMtGo
Basically, my phone was on sleep for several hours, turning the screen on 4 or 5 times just to check for notifications. I went to the power management, saw the graph steady while it was on sleep mode (battery at 64%), then in 50 seconds, 10% disappeared as shown in the second picture. Can somebody tell me what could be the root cause of this? I'd highly appreciate it
note: I took screenshots because i noticed the issue before, good thing is that i was able to replicate it.
The battery stats don't always update when the phone is asleep. This has been mentioned by others.

Thanks for this, but my friend gets around 3.5h of screen time, i only get 2h. We have the same phones with similar serial numbers. We both have 3G always on (except when there is wifi) and both use auto-brightness.
Can you please guide me on how to diagnose? I have Carat and it isn't reporting anything suspicious.

Oh, you didn't mention this in your first post.
Both having auto brightness is hardly a fair test, maybe he uses his in darkened rooms and you use yours in direct sun.
I notice your phone signal is bad, which could cause battery drain.
I used to get about 3 hours use, auto brightness in darkened rooms, WiFi and data always on. My soft buttons died, sent for repair and now I get 4 hours with similar usage. They said they replaced screen, but they also replaced the case. Have no idea if they replaced the battery. Both phones arrived with an empty battery, but I suspect the first one was empty for longer which may have damaged it.

How can i check for the battery health? I mean actual health percentage of what it should ideally be.
Hello all,
I recently purchased a LG G4 Back In July , on Verizon, switching over from A Galaxy Note 3 (Tmobile). Honestly I really really like the phone, but I think the battery life is pitiful for a $700 dollar "Flagship" phone. I mean not once has it ever lasted the full day. I had to buy a spare battery kit, with 2 batteries, and days when im out from 6am to late at night, I go through 2 batteries, and have to put the 3rd one in. I mean , this is simply unacceptable for a phone like this.
Also, the camera is excellent WHEN it works. A lot of times, it doesn't take the picture right away, there is a delay, and many times it falls out of focus. This is certainly not the high quality camera they advertised.
I am hoping there is a way to fix these 2 issues, mainly the battery issue though because it is awful in my opinion. Is there any tweaks or fixes for these issues?
You've barely given any relevant information other than how unhappy you are with the device, so I would suggest that you elaborate on that.
You could inform us if you're a heavy/light user, if you keep NFC, LTE, Bluetooth, Syncing, Wi-Fi, on during the whole day or maybe if you are used to 100% brightness display. Maybe you should check in your settings what is draining your battery and provide us the info.
I'm having a pretty good experience with the phone so far. It surely lasts a whole day with 3:30 to 4h SoT. I don't even need/have a spare battery.

One person having an issue doesn't mean it's not a great camera. You'll find it's likely still the best flagship camera of any OEM.
Battery use is so dependent on which apps you run, which mods you have, how often the screen is on, what brightness, signal strength, wifi, bluetooth, etc etc etc...
I came from a galaxy s3 and reckon the battery on g4 is awesome. I use it solidly on internet for 2 hrs a day (to and from work), check messages etc through the day, usually internet at lunch. And then evening time check facebook etc over WiFi infront of telly.
I unplug at 6am and plug in around 11pm with around 3% left. I bought a 2nd battery and only needed to use it twice. It has to be how you're using it.

13 hours on battery for me today and still 71% left. Light usage but it does illustrate that the battery life can be excellent.

of course, you can get excellent battery life on every smartphone - just put it in aeroplane mode..
I get MAX 3h of SOT time on my G4 - this is with fixed brightness at 65% (at all times) and only wifi and 3g enabled (NFC, bluetooth and everything else is turned off all the time)
to be fair I have yet to own a smartphone that lasts me more than 4h SOT..
the thing that annoys me the most is the broken knock code used to unlock the phone - it works 20% of the time at best
its a completely broken feature LG has not properly addressed since launch of the device (I am on V10e software)

There have been numerous firmware updates since. Have you ever performed a full factory reset after getting those updates ?
If the answer is no, then this is one potential reason for poor battery life. What you could try is to clear the system cache in recovery. Note, i said system cache not apps cache. Idea here is when updates come in there could be conflicts and it causes the system to work harder. clearing system cache might help, if it does not then the only option is a factory reset and then a manual install.
not restore. You install apps in batches, monitor, then install more and so on. You can restore contacts etc. but apps themselves will have to be reinstalled. Sometimes apps go rogue and have to be reinstalled. Its hard to tell which app is causing the issue. Otherwise you could just reinstall whatever app that seems to be taking up more than it should be.

What are you doing on your phone ? mention apps.
How do you access the net. How good is your signal. What are you doing when you access the net.
Also, the camera is excellent WHEN it works. A lot of times, it doesn't take the picture right away, there is a delay, and many times it falls out of focus. This is certainly not the high quality camera they advertised.

What types of shots are these. It can happen with portraits some times. It will focus on the background behind the person instead of the person and the face becomes softer and the background very sharp.
For this set focus little above the chest instead of the face. If they are wearing dark clothing this will cause other issues so focus on something else at equal distance that isn't dark.
Always check the shot at the pixel level soon after you took it. Rather than at the end of the day.

Just to clarify: I had everything turned on for those 13 hours - wifi/data/bluetooth/GPS. I also made 2 phone calls and did a bit of Chromecasting using the BT Sport app for a couple of hours. Or to put it another way, I didn't take any measures at all to preserve battery life.
I used to complain just like you're doing OP ( @dredmentia ) and fixed it all with a Zerolemon battery .
Is the phone bulky/no leather back/not easy to handle... , it sure is but if battery life is crucial then it gotta get fixed.
End my day anywhere between 7 to 13 hours of sot depending on WiFi or 4g and high CPU freqs, tried light usage and hit 3 days with 12 hours sot. Snap/insta/twit/fb/periscope/... Nothing kills this battery in a day.
When and if we get a kernel I'll move back to factory battery at least then I know I'm in control of how CPU works coz while optimizing the phone for wakelocks that's the only thing I have no control over...
As for now I'm just trying to burn thru this battery every day so I can charge it every night...
Last phone was a Z3 Sony and that really grabbed my attention with its battery life in stock form, almost too perfect, Almost.

LG G4 Battery Case, ZeroLemon LG G4 8500mAh TriCell Extended Battery + Soft TPU Full Edge Protection Case (Compatible with all LG G4 variants) (4897010519648)
It works with the USB charger that came with the phone ?
Did someone seriously just ask me if I kept the brightness on the screen at 100%???? Obviously im not doing that, im not some idiot. I know the screen eats up most of the battery. I keep the brightness extremely low way under 50%, or on auto., The battery still last a short amount of time. Its not acceptable

Then maybe something is wrong with the phone. I got also 4-5hr SoT.
It can't be just 2hr.

Answer everything asked in full.
Greetings all. I have a major issue with my A3's (2017) battery and it seems like many people are having the same issue. Despite the number of users experiencing this, there are no solid solutions to be found anywhere. I've tried absolutely everything; from changing my WiFi settings to disabling almost every built-in app. Even when the screen is off my battery drains at almost 5% an hour, regardless of whether AOD is turned on or off. It doesn't seem to make a difference whether I'm using WiFi or HSDPA either.
I'm unable to post any links, so no screenshots unfortunately. Android OS is utilising 24% and screen is at 18%. My battery usage graph is at a 45° angle: Not the nice, relatively flat line that you would expect to see.
If anyone could shed some light on this for me I would greatly appreciate it, as I'm on the verge of smashing this POS with a 4 pound hammer.
It almost sounds like it's something wakes up the phone a lot during deepsleep or something.
Try to install wakelock detector from play. Maybe it can give a hint of what's draining the battery.

Try use Gsam for identify your problem.
I'm having the same problem and i think it's becuse of the new update i installed recently. On the January build(with the January security patches) I had way better battery life. Attached a screenshot so you can see the new build number. Do you think if I revert to the old firmware this will be fixed?

I also thought of that but unfortunately I haven't rooted it yet because it's still fairly new and I'm not sure if I may have to return it or not. I might just have to root so I can try get to the bottom of it.

Ok so I installed GSAM and it's reporting that my screen is using 61%, even though my screen brightness is set to almost as low as it can go. It's used 18 percent in just over 2 hours. Can you confirm if this is normal? Also I noticed that Android OS stay awake is at over 11 hours. Seems a bit much to me. I'm thinking I should just root it so I can do some proper diagnostics.
Thanks for your help guys.
If you do not mind losing the warranty, do root. But I would first make the factory reset and have done testing without installing any other applications.

1) factory reset device
2) drain battery till 0%
3) charge it to 100%
4) Use sleep/doze mode for apps
5) Use power saving (mid/high)
Hi all,
So i got a HTC 10 UAE edition from a guy two days before. He was selling it at a reasonable price and i bought it from him.
The battery was draining quite fast and i thought it might be a software issue and i installed venom rom, but problem still existed, so i turned back to stock 2.41.401.41 (Which was very hard though) .
Still the battery is draining so fast. The charger came with the phone( Quick charger ) was also not working and now i'm facing the phone's battery is draining so fast. I'm very confused whether that guy have cheated me or not. If this is a hardware issue i think i have to contact that guy soon.
adb battery stat gave me 2580mah full charge capacity and here, i'm attaching the GSAM battery logs.
Please help me on this
Thanks
Edit: Since the original charger isnt working, im using a oppo 5v- 1A charger, is dat matters on battery drain?
Mine was doing the same as yours, quick charge also stopped working. I changed the cable and it solved it for a few weeks, but the drain started again and quick charge stopped again. Tried ruu etc but no luck. I've sent mine in for repair under warranty and should get it back Monday. My guess is either the charging port is faulty or motherboard but will find out next week.
I was having the exact same problem. I downloaded an app called Lspeed (It's also on the playstore) and did some tweaking in that app as well as used the Enable doze for GMS Magisk Module and now my kernel and android system are on par with each other as far as battery drain goes. Not sure why there are only a handful of people that experience this problem but i'll edit this post with screens of my lspeed config if you want to give that a go!
Edit: Config uploaded. Some of those options are personal preference but take a look around and test it out. What you'll most likely want is to enable the light doze optimization and disable the debugging. That will most likely help in your situation.
Very strange, I'm experiencing this issue too, always receive around 2-3hrs of screen on with very high kernel use during standby. Tried flashing Leedroid, Element X to no avail.

I'm currently running on pure stock. Will try this method soon. How was your battery standby before doing the tweak ?
Have you tried wiping cache? Mine drains fast depending on the load, which is usually pretty heavy daily. Plus, I don't dim my screen much. Never knew the advice command for battery. I gotta try that.
Stock Rom
Okay, so I got fed up with the battery life I've been getting and have looked more into it, I've managed to reclaim a lot of the longevity I had before updating to Nougat without hampering UI fluidity. For reference, I'm using Leedroid 3.9 with Element X v1.08 and was getting around 2hrs screen on, android system and kernel had the highest usage under GSam.
bilibox has the right idea, my idle drain was very high, L speed and Greenify both have options to enable a more aggressive Doze which worked pretty well, I lose ~10% battery overnight vs a shocking 20-30% before. I still felt battery drain was too high when active, I combined ivicask's PNP mod (balanced) with some little governor tweaks in EX Kernel manager, basically, I'm using interactive on the little cluster and elementx governor on the big cluster (which tends to be slightly more conservative in my uses). I also set min performance to 0% and downclocked the big cluster to 2Ghz, I'm focusing on these cores since they were draining a lot of power in my case.
It's not a super extensive list of tweaks nor something we haven't seen before, but I manage around 3.5hrs of screen on now which gets me through the day. Before I would have to top up around early afternoon, the phone is also really smooth and I'm happy with how everything is running. I hope this helps some people out!

Still its bad that a 3000mah battery with a smaller screen compared to other flagships giving a very low battery backup just because of software bug. From reviews, i can see that MM is giving fine SoT as well as standby. One thing i really cant is the standby. I cant even go out for a day trip. The battery will die in just 10-12hrs even on standby.

That's unfortunate to hear, my battery life is pretty much in line with my friend's S7 now, newer devices can get away with larger displays because the 835 is a bit more efficient.

I restore my phone and did all updates again. My battery still seems to drain very quick .in an hour with some navigation, and little screen use It went from 20% to 1 percent.
I've taken excellent care of my HTC. Before this, I had HTC 8 and loved it, until right at the 2-year mark, a small area of the screen stopped working.
This is the second time I` experience this, and sadly there won't be a third., especially after new HTC removed the headphone jack like the iPhone ... RIP HTC
Well to be honest the past couple days were to weird to me usually i get 5 - 6 SOA over 13 hours
now i get 3:30 - 4 SOA over 13 hours, same usage, and i have noticed that google service consume most of the power, i have installed doze program and kept my eye on GSM battery Monitor, after all the google service kept the kernal wake up for a long time, and keep running the hardware on the full abilities
I unistalled Gsam battery monitor and kernel usage is back to normal...

Was having the same issue, and had been searching for weeks to try and solve this. Tried rooting, factory resets, ROMs, everything.
For me the issue was Google Sync, in particular Contacts and People syncing. I disabled those and everything is back to normal. There was a program called Google Contacts Sync (Apps > Show System > Google Contacts Sync). I cleared the data on that, and then went into Accounts and Sync and turned everything off. That fixed the battery drain. I have tried turning back on Gmail, Keep and a few others and still have great battery.
I have the same issue and I don't know how to fix it. Please help
Hi guys!
I have a serious problem with a used A5 (2017) I got from some friends. The battery life is abysmal. I already changed the battery and it didn't change anything.
It is running on Android 8 Oreo. The most serious problem, I think, is that the phone even discharges when it's powered off. I tried using the latest hadesrom, but it didn't changed a thing. Lifetime is around 12hours, doesn't matter if I run some apps or just let it lie around in standby. I tried factory rests and some battery saving apps... nothing works. Is there any way to get better battery life? Thanks in advance!

You could try the naptime app. But I don't think my battery life is any better than yours.
The a5 2017 has a famously good battery life.
I am not a heavy user - make and get few calls and mainly use it for receiving emails and a few texts plus a bit of web browsing.
Occasionally listening to podcasts.
3 days battery life is easy for me - reckon I could get 5 days if I just left it sitting quietly.
If it's going flat quickly even when switched off, it sounds like a fault somewhere.
Don't know what else to tell you.

I never tried letting it sit, but if I just left mine alone it would last for days too. But if I am gaming on it, it will go down to around 50 percent at noon.
wow - 3 days life battery!! I can hardly get to 2 days, without heavy us - but I would never try to change the battery -> sounds too complicated
One thing that is worth looking at is the Always on Display (AOD).
I found it sucks a lot of power despite the claims that it 'doesnt use much'. It seemed to use around 1% an hour - I guess thats around a quarter of your battery in a day. So unless you find it useful either turn it off - or set it on a schedule for when you actually want it to be on.
Battery life is always sujective and depends on what your phone is doing - gaming will burn through a battery like nothing else.
The OP said the battery drains even when the phone is switched off - That sounds like a hardware fault. The battery will gradually drop when switched off - but it should take months for a healthy battery to drop much if the phone is switched off.

1 percent an hour doesn't matter to me lol. I am a heavy user so I charge every day anyway.
