[UPDATE,FIXED] Battery lowered 10% in 2hrs while on Airplane Mode/ Wifi Off.

I was in a class that is from 7AM-11AM. The classroom has no signal whatsoever so at 7AM I put airplane mode on, didn't turn on Wifi, closed all open tasks and just for the heck of it turned off background data.
When I put all this into effect, I was at 91%. At 9AM I see that my battery went down to 81%. How is this possible? I was in airplane mode so nothing was synching or downloading, no programs were running in the background or anything at all. On my previous phone (Nexus One) under the same situation the battery would have been at 90%.
Phone Idle- 34%
Cell Standby- 30% (Time without signal 85%)
Am I missing something here? Can someone please elaborate why this went down so much for basically doing nothing.

Did you drain your battery completely the first 5 to 10 times charges, when you first got your evo? Many people claim that's how to he the maxium battery performance from your battery on any phone

Normal. I lose about 10% every 2 hours.

Yeah but I wasn't even using it and it was in Airplane mode. That can't be right

WOW... sounds like its your CPU thats still killing the battery??? You don't have it rooted or running any cutoms ROMs on it?
We SERIOUSLY need to get a UV kernel on here and underclock this thing when its asleep... So many battery drain issues.
Your issue is REALLY strange though.. I was in LA yesterday and mine didn't drop that fast for like 2 and a half hours... Very interesting......

This is bogus. Don't bother doing this. That was something that was needed back in 1999 back in the days of NiCad and NiMH batteries... It doesn't help LiIon one bit.

20 hours of battery life is pretty good. I think the record is like 62 with everything completely hacked down. I get about 4-6 in full on usage.

I understand that 20 hours of battery life is good but If I was using the device in those 2 hours I wouldn't be worried. But I wasn't, it was completely IDLE with all the radios turned off and programs killed (advanced task manager).

that is NOT normal lol when my phone is on standby i loose about a percent per hour overnight....

Deactivate any syncs you don't use. Make sure your phone is set to CDMA. See what processes your phone is running that are killing the battery and disable them.
I get about 27 hours on my battery.

I fixed the problem. I rooted 2 days ago (evening) after getting such bad battery life and I flashed Damage Control 3.0.
Today after 2 hours and 30 minutes of being under the same exact conditions as my original post (30 minutes more this time) with Airplane Mode, Wifi Off, Tasks Killed,etc I only lost 1%.
I went from 93% to 92% in 2 hrs/30 minutes which is a hell of a improvement in comparison to losing 10% in less time (2hrs) with the same exact circumstances.
I am extremely happy now. Oh and by the way, yesterday I got 14 hours of usage with this ROM which for me was unheard of before (4-5 hours)

Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the LG G5's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!

Standby Is Good - Unless
If I lose signal for a long period of time I will take a battery hit. Otherwise, no problem.

Standby drain...PHENOMENAL!!!
Sometimes, over the course of an hr, it won't even lose a percent! Amazing, even compared to the Note 3, which was awesome battery-wise!

my H860's standby drain is abysmal.. It drops 15+% overnight (about 6-7hrs). How are you getting such a good standby time? I disabled Facebook (which was installed as a system app for some reason) but even then the best I got was 9% overnight..

Same problem here. Battery drain while phone is idle is absolutely horrid. Can't for the life of me figure it out. Under settings in battery usage, the only 2 things I show with significant battery drain is screen on and phone idle.

Bad signal (1 bar or less) can severely affect idle battery drain. The always on display does take some battery. Try turning it off to see if it makes a difference.

Yeah where we live is great signaland one of the first things I did was turn off the always on feature. I still have the drain.

No idea!!! I'll keep an eye on drain again...but I gotta say, I found it to be great! I'm almost always on Wifi, not sure if that has anything to do with it.

I too have the worst battery life I've ever had on a brand new device. I don't know what else to do but sell the phone.

I sure wish we could figure this out

Was doing some digging on this exact issue. I was getting a ridiculous battery drain from phone idle, which I didn't have for the first week of owning the phone. For the life of me I could not figure out what I changed, but I think I may have found a solution. I have the AT&T H820 and it turns out other devices of the AT&T variant (galaxy s6) had terrible battery drain with Enhanced LTE selected. I have just disabled it and will report back in a day or two to report the results.

Thank you for the feedback on this. I have the Verizon edition and I've been looking for that specific setting since you mentioned it. I don't see it in my menu. I'd imagine you went to the mobile data menu under some and it was in the somewhere?

Thank you.

I have TMobile varient. Yesterday, I tried selecting 'Restrict background data' option (Settings > Mobile Data > Top right menu and select 'restrict background data' checkbox). So far its been better than yesterday.

I use Shutapp to end running apps and turn the phone over so the light sensor is covered and the always on display shuts off. Battery seems on par with my G3 which is the same size battery.

I have no stand by drain on my AT&T version. I have aod off and this is on my nightstand. So Wi-Fi enabled. Location and Bluetooth off. I charge to 100% then restart the phone and then unplug for the rest of the night. I will wake up anywhere from 6 to 10 hours later. Weekdays and weekends vary. But I will always wake up at either 99% or 100% my stand by works flawlessly. Just my process.

my colleague has this and his battery drains while on stand by. not the best!

Inconsistent but normally good
In the second and third days that I had this phone it seemed to lose 1 % per hour which I feel is pretty good considering I had always listening for "ok google" and the fingerprint scanner on. I have no sim in the device yet. The first night it went from 80 to 2% on standby though that could have been just because it was the first night. I don't have always on display on.

I have an international version (H860) on AT&T network for about a week now. AOD is off, Wi-Fi is on, GPS is on Battery Saving mode. Every night, the drain is about 20%. Battery usage shows Android OS and Phone Idle being the top 2 uses. I reset the phone once already. The phone is set up the same as my G4, same set of apps. The G4 has only about 1% drain overnight. Can this be a defective unit?

[HELP] LG G4 battery percentage jumps

Title. H810 no root.
I'm aware the battery life on this one is not really good. That in mind.
-Example, (nothing running on background, everything but wifi off) using it normally until 14%. Pushed sleep button.
-Turn screen on like 5 mins after and it was 15%, used it a bit then again screen off.
-Turned screen on about 6 minutes later and it was 5%.
-Drained it to supposedly 1% then phone turned itself off.
-Turned phone on again and it was 2% and stayed like that for 10 mins while scrolling twitter with 30% brightness, until it turned itself off again and this time battery is to low to turn on.
Tried factory reset, draining till absolute 0% then 100% multiple times but so far nothing works.
Battery's health is good and factory original, no water, no heavy drops.
Let's say i root it (as far as i know its possible in all models), question:
Is there a way to push battery stats to make battery readings accurate?
Or what do you suggest? thanks.

Hi,
What you have is normal.
My owen device jumps frpn 12% to 15% after heavy and log use, thats normal, cause battery is cooling down/pre-ucomputed Energy is not consumed and Battery is calculated new.
The other Jump from 15 to 5 thats somthing you should watch closer. did that happen often?
all in all I have a sugestion but answer this first.
How old is Battery and usage time? (heavy or Soft? SOT? and so one)
Battery readings denpend on the Kernel. You are Stock i think?
Titan Kernel gave me awesome Display Sdreen on Times but battery is jumping too.

Thanks for replying!
Well thats one solved, it wasnt a sudden jump but rather a few minutes discharge doing nothing at all.
Battery is as old as the phone, 2015 and usage, i dont know for sure since it's an import US carrier phone sold to me locally, seems like it was a test phone like the ones you can try at stores. I would say battery use isnt any different than it would be in a daily usage and even if not, would be very rare for a li-ion battery to degrade in such a small amount of time. Gonna ask the seller.
Another thing i notice is very fast battery drain while playing music. I listen to music from home to work, like a 1 hour trip and when i got of home with 81% when i get to my job im at 68%.
And yeah stock everything with android 6.0, as i said currently not even rooted.

Sounds as if the Battery has some Altered Issues. How Often do you charge?
with Music You meen Mp3 or stream? (stream drain battery much faster)
Try custom Rom and titan kernel if u dont need stock services, otherwise rootand use greenify or other.
on Stock i Had SoT of 2 hours max. now i am back to 3 Hoeurs (i´m heavy user some days...)

Already using greenify. Charging 2 times a day, 1 before going to work, 1 when i come back, plugged while using it.
MP3 from stock music app, since i read somewhere a 3rd party music app caused an user a battery drain-
H810 has locked bootloader, do you know any flash tool?

Greenify is much better with Root
first you must unlock your Bootloader.
there are 2 Otions at the moment. Official (don´t know if possible for H810) and USU by @steadfasterX

read and choose for yourself if that is what you want

Just by a new battery. Original battery can be found for about 8$ at least here in Sweden..

I believe this is normal.
My H815 had it with both the original and a new battery. It used to be really bad when you charged it to 100%, restarted and it would drop immediately to 80%.
Also, especially on stock LG stuff (the graph on custom ROMs seems to be smoothed out), the battery graph was a mess of random spikes and dips

S20 serious battery drain issue

My s20 Exynos is draining 1 percentage battery every 3 minutes when screen is on. Location , bluetooth, aod and all are off including Bixby. I'm using single sim and signal is very good. Using wifi for data. Can't understand what is causing battery drain.
Is my battery fault? I purchased just 2 weeks ago and it's really frustrating me.

Thanks a lot for your list. I'm going to do factory reset and check how it improves. Its a big pain moving all files to pc and copying back. I'll update my status in some days sure. My sot is very bad now, getting 3 hours only

For the moment it's normal let the phone learn your habits and your usage do the update and do 2 or 3 full cycle charge (20 to 100%) after that it will be good if not you can ask a replacement because you have a damaged product

I had similar issue on my S 20 Ultra but even worse. After update to One UI 2.5 I had huge battery drain,overheating, can not even reach 120hz and had lags every 10 secconds no matter what I was doing.
I tried to: Wipe cache did not help, new function apps optimizer did not help, restart did not help.
I found that new "design" Edge panel ate approx 8% of battery over the night so I disabled it ,restarted my phone and everything went back to normal.
I never had such a problems with any phone in the past. This is embarrassing!
Hope this will work for you too!

May I know how did you know edge panel took 8%?
Because battery care does not show system apps power consumption. Accubattery and gsm battery also did not show system apps power consumption.
I struck on finding which one is causing this huge power consumption.

settings -> device care -> battery -> battery usage-> edge screen
edge panel is a part of edge screen "app" which I can normaly see in the list.

I've checked it. It shows only 1% was used for edge screen. Samsung has hidden the feature of showing system usage like screen , wifi, cell radio signals etc.
Why the hell they did this. If it is available we can easily find which one is causing issue

Any ideas?

Try running med power saving as a test, see what your drain is then.
What is showing as your biggest battery drainer? You can try grabbing galaxy labs and seeing what's going on via battery tracker. You can find galaxy labs in the galaxy store, if it's not there then someone posted the apks in the apps forum as it's only available in some regions. . It gives you a little more granular visibility in batt usage.

check out gsam battery monitor from google play store. You will need to enable permissions to allow it to collect enhanced stats. This is done via ADB ( Android Debug Bridge), which is quite a simple process. The app walks you through enabling it step by step. This may help to identify what is going on. I can't remember how much detail it gives on system processes. But it is free, so worth a try

Newest update has also tanked my battery. Have a S20 snapdragon.

welcome to the world of exynos

see my post #311 here https://forum.xda-developers.com/galaxy-s20/review/screen-time-t4010447/page32 it may assist with some options to tweak to help with your drain. I got the new update a few days ago and my battery use is still fine, around 3% drain overnight for 8 hours.

Battery and Lag
I have the S20+ and when the new software BTH5 was installed...it was a nightmare ...huge drain and lag was terrible...I wiped cache no difference then factory reset which I hate doing due to the reinstall........however it is absolutely perfect having done that. hope that helps

Install Better battery stats from plays store, give it all the required permissions, do a full cycle and check what is draining your battery there. It's a very good app, perfect for troubleshooting battery problems.

There is no app causing battery drain because I have put all apps in deep sleep mode. Accubattery and Samsung labs battery tracker showing apps power consumption only and not hardware power consumption.
I've charged for 92% and it went to 82% in half an hour of sot and 2 hours of screen off.
This is very annoying me to find out where is the problem

No issue here. Do a factory reset may help

Did you try any of the suggestions from my post 5 posts up?

Question Standby time drain

I just came from S21 Ultra and I'm noticing a huge drain in my Fold 4 about 15% to 20% overnight and I'm not sure if it's normal nor where it comes from.
I disable AOD during the night. I used GSAM to try to figure out the culprit with no luck.
Do you have any thoughts?

I leave mine on a wireless charger overnight so not sure then, but it seems to barely drain anything through the day unless I'm actively using it. I did notice the first 2 or 3 days though it seemed to drain a lot faster while it was "learning" my habits. Now I have no fear of getting through a full day of heavy usage even though I've set the charging to cap at 85%.
A lot of things can affect it. 5G data takes a lot more power than wifi and I run wifi at both home and work so I'm rarely outside of a wifi range. I also use wifi calling. I don't use AOD except when there's a new notification.

I would speculate there is an app on yours not allowing deep sleep. Mine so far has only been dropping 3-4% through the night.

I thought so at the beginning but looking in gsam I found out that combined app cpu is consuming a lot of juice. I'm a long time avid android user and I've looked into all the possible causes but surely I'm missing on something.
EDIT: battery drain while I'm using it is superb, but it drains while standing by.

I noticed with the Fold 3 it took a few days for things to settle and apps to sleep.
But def check what apps are NOT going to deep sleep. Then add those that don't need to run in the background.
I have the 3, waiting on my burgundy 4, and with very little use during the day I get good battery. At night, it would drop but not by 15-20%.

I guess it'll figure out how to last longer once it learns my behavior. I've installed battery guru to monitor things and hopefully catch the culprit.

I do recommend taking the time and settings the apps that don't need to run in the background to go to sleep. I don't need a calculator running, so it can sleep. And so on.
But yeah, you'll see things level out.

Be sure to report back whatever happens!

Sure, thanks.

I don't know if I've ever had a phone with better standby drain than the Fold 4. Just an experiment but I took it off the charger at 3PM yesterday and didn't touch it until 5:30AM this morning and it was at 95%. This is just the 3rd full day of use. I am using Nap Time with a couple adb commands to give the proper permission for an unrooted phone. Also turned of continuous scan for wifi and bluetooth, disabled Bixby and a lot of the bloat too.

Hi

Update: so I let it stand by and I guess the culprit is oneui home app and it's strange to me since it's drawing more than it should and keeps the device awake, and for some reason keeps the screen awake as well.
I've cleared the cache and force closed it and I'll see if this fixes the issue.

I just came from S21 Ultra and I'm noticing a huge drain in my Fold 4 about 15% to 20% overnight and I'm not sure if it's normal nor where it comes from.
I disable AOD during the night. I used GSAM to try to figure out the culprit with no luck.
Do you have any thoughts?

1% standby drain per hour on ANY smartphone is exceptionally good. Looks like you are 2.5% drain per hour. That's not terribly bad though either.
Try putting phone into flight mode before you go to sleep. This will tell you if drain is radio/app related or the core OS.

If its home, maybe a widget that's loaded doing polling not allowing deep sleep? Worth nuking them all see if it makes any difference.

What app are you using to check your battery stats?

Battery guru

I like battery guru so far. I use to use Better Battery Stats from here on XDA but it doesn't seem to work as well as it use to. I noticed that I have nothing logged for wake locks, is that a limitation on the Fold 4?

At this point, I give up.
My fold doesn't sleep at all even after a factory reset and wiping the cache, I can't figure out what is causing this issue. It's drawing anywhere from 5% to 10% per hour while standing by.

I advise you to install "gsam battery labs", and in the settings of this app enable "show more statistics" (this require a PC with adb minimal package installed, USB debugging on on the phone and a USB cable).
It can tell you which app uses what % of the battery and for what reasons (downloading, GPS usage, etc), even for system apps, and most importantly even when the screen is off or the phone is dozing.
This as been my go to app since using android phones, in combination with accubattery (which doesn't show system packages or anything usefull while screen off).
As for my ZF4, when the screens are off it is using 0.5% per hour during night time (deep sleep) and 0.9% during the day (light sleep)
