S8 battery issues - Samsung Galaxy S8 Questions and Answers

Likely unrelated to the ROM (hadesRom 6.0), but my S8 has been having weird battery issues as in almost instantly draining once reaching ~30-40% battery and just shutting off. Up until the point battery drain is normal if not better than it has been before, but this is still a major issue.
Any ideas/help?

Mine also. Once it reached below 30%, it will suddenly drop to 10% even on idle. It's been more than a year since i got this phone, and i just recently rooted it and install a new custom ROM. is it because of the battery itself? degrading?

Good day.
A friend of mine had an similar problem and solved it by disabling the system app called "ARCore". It's an google augmented reality plataform app. Try disabing or update the app.

Maybe it's also just an error with battery percentage display, but battery performance seems pretty poor then.
I'll try disabling/freezing ARCore and see if this changes anything ^^

This is very common sign when battery is going bad when u start to have these drops . Logically battery should be replaced .

battery drains.. sort of

Does anybody know sone work around regarding this? Because its starting to annoy me, have you ever experienced when you are using your device,the battery warning suddenly pops up and says that you must charge already and the battery percentage suddenly changes to 3% eventhough awhile ago there is still 50% left, but when you reboot it chages back to 50%, what could be a possible culprit, this happens a few times to me a day and im tired of rebooting everytimethe warning pos up.
Any advice is appreaciated
Same experience. I posted this a while ago but no solution.

well this isnt an acutal solution but have you tried actually draining your battery down to 3% recently? By doing that you are "calibrating" the battery life sensor and maybe that will cause this issue to occur less frequently?
This happened to me once so I did that and havent had a problem since. Hopefully it works for you!
but how do you power it on if thinks the battery is critical
Somehow if ido a reboot it just goes back to normal..maybesomething is messing up with the battery sensors,i did let it drain but some how it still the same, i had read on a similar thread about a bump charge or something maybe i could try that and lets see from there
on verizon tab SCH-I800 - does the same thing ... mine seems to happen around 33% though. (i thought it was something with the 33% .. since it would drop down to 3%) ..
i think samsung should really push out an update to address some of the glitches in these tabs..
Tried the recalibration thing. Problem still exists.

thats a similar issue i get,. Yes i tried the recalibration charge also and still having the problem, i did a factory reset also and it did nothing.. Im really desperate for some fixes..
Mine jumps from 15% to 3%. Quite annoying, I assumed that it is because it is poorly calibrated and so it doesn't realise its actually critical until its 15%.
I tried calibrating it by running it until it switches off, and then fully charging. However, that didn't work.
If in reality the battery is at 15%, then its a pretty bad software bug.
Maybe deleting the battery stats solves the problem?
I think its getting worse on mine now after a full charge after i remoce the charge around 2min. It says 3% again what the heck?

Tried flashing with another rom but no help. Start to wonder if this is hardware related....

try to flash it with rotohammer rom JHA/JMC it might fix the issue. My problem with GT was battery draining too quickly but after flashing it's much better now.

This worked for me too, however I had to do it 2 or 3 times. I haven't had any problems since.
I think i sorted it out also by calibrating battery,i removed the battery stats using the root explorer,now im still observing the progress
Brand new sprint tab, only installed the over clock kernel first week i got the.
Today, which would be week 3, i experienced the 35% to 3% drop instantaneousness..... So, im draining the battery, and hopefully doing a full recharge...

I also have a sprint tab and it is three months old. I have not put another rom on it, only rooted it. It also has developed this battery problem recently. It will go from 53 to 3 all of the sudden.

Not too sure what's the issue but it does sound like a program consuming too much CPU or the battery calibration issue.

[Xperia X F5121] Incredible Battery Life on Nougat (Concept 38.3.A.0.107)

Just wanted to point out, without evidence yet, that battery life on Nougat (Concept update 38.3.A.0.107) is amazing. I'm talking about days here.
¿Anyone else experiencing this?
As for the evidence, I will charge my phone to 100% today and upload a battery life screencap as soon as I can.
What? I need that firmware! My battery goes from 80 to 70 in 5 minutes On screen time!!!
Hi,
Just a quick update with a screenshot. Just 2h short of a day with 14% to go, the mostly horizontal part of the graph happened when I was asleep.
SOT for that is 3h13m

Um... ok?
Maybe I'm coming from a terrible phone and this seems very good then.
Nevertheless, I can tell you for sure that my phone isn't dropping 10% batt in 5min SOT.

well now that I have applied some fixes and calibration it isn't in mine either. I am not sure really, but 3 hours of SOT is just not good, and Im coming from a bad phone too
I'm thinking x-reality might be disabled afteryour update. My screen takes up 30 percent battery with x-reality on.
I never havwe x reality on.. seriously yoy think I didnt check it or what

I dont understand.. my phone is brand new, I have optimasations, underclock and everything except wifi is off.. what am I doing wrong? I have also calibrated the battery, full discharge ans full charge, its not any app im using since with stock and. nothing. installed battery runs the same.. Also the camera is worse after the drm fix than before drm fix (too much noise) the hell is wrong with my phone??

you too are in concept rom? because that is standard now battery going way too fast, try installing gsam app and give permissions via adb so you can check which app is consuming too much power, i have done it but i still can't figue out what is causing it

No, I am using the poison nougat rom. Actually, I have been using gsam for 2 weeks I think, just like you I cannot find the problem. My SOT is 3 hours, 4 hours at best. And keep in mind that is with very simple usage , not any intense apps or games

Every phone has these kind of problems
My battery life is shocking. I do use my device a lot so it's understandable.
There is battery tweaks out there to help people with problems. Someone will bring something out or find something for our devices

Correct, but in our case it is beyond normal. 3 hours O-S-T is not normal for this phone in any case

Yeah, I understand what you mean, the problem here is that we do not know if it's connected to software (or somehow to the bootloader / root probably not though) or if it's the actual phone being faulty. I doubt it's faulty, I have absolutely no problems apart from the drainage

Weird Battery Problem

Hi.
So, I have a S4-i9505 running "Optimized LineageOS 14.1-Stable3" rom.
It has been a while since my battery is overheating a lot when I'm doing something that requires more performance from my phone, like playing a game.
And the weirdest problem is that my battery is dying with 45%~40%.
At first, the phone was dying at 15%, but day after day things got worse and it increased the percentage of battery to die. Like 15%, then 20% and goes on until 45% now.
I don't even have to say that's awful and veeeeeery annoying.
And usually the phone just dies when I'm using it. Whenever it's idle it doesn't die.
Does someone knows what should I do?
Change the battery. Most probably this one has reached the end of its life and it will only get worse, until the point where it won't even turn on anymore with your current battery.

Idle Battery Drain

Hi All,
From Past 2 weeks... am Facing Phone Idle Battery Drain...
I have tried everything.... - Factory Resetting, etc....
The problem even persist in Safe Mode also...
Is it a Hardware issue ? or A Clean system Reflash might help ?
PS: My phone is not rooted.
For me after I'm uninstalling the snaptube, all it's turns normal... Maybe you use some app has draining your battery ?(software)

I also thought the same...But I didn't install any new apps other than Pixel Launcher.... And Now...I Uninstalled it.... Still facing the same problem.
I guess it is just the horrible LG software. I also experienced extreme battery drain in standby and could not figure out why.
I decided to flash the Resurrection Remix ROM onto my LG and look at that... Amazing battery life with the same usage and same apps installed.
My battery now drops 2% over night. With stock it was 9-10%.
I know it might not be the answer you are looking for. All I am saying is: maybe the Oreo update will help for Stock solutions.
There are reports out there that show amazing battery life with stock but they often disable a lot of services which in my eyes is not the purpose of a phone. Other than that... Try your luck with Greenify or something like that (could be hard to reach real results here without root though).

Hmm.... But I hav paid 760$ to buy this phone.... Why Should I settle for less ? If its a budget phone...then Ok...but this is a Flagship Device.... I am going to take this to Service Center. These Battey Problems are irritating me.
As far as I remember, that idle battery drain is known issue in Android 7.0 and our precious G6's have 7.0 and probably will never get 7.1 which has this problem fixed, LG rarely releases incremental updates, mostly only releases new devices with newer software (V30 has 7.1, Q6 also has 7.1 and their battery life is great).
7.0 bug causes "Phone Idle" thingy popping up in battery stats almost always on top, sucking up to 1000+mAh of battery in my case so I have to charge the phone almost every single day which is a little bit frustrating considering phone's battery and that it lies unused for around 8 hours every day as I have to leave my phone in locker room when I'm at work. This is the only thing that I hate in this phone.
We have to wait for Oreo... which also makes me a little bit nervous because 8.0 also has many bugs... Yes, 8.1 is right behind the corner but that strange LG update policy will probably halt our phones on 8.0...

Being able to have numerous apps for different purposes downloaded on your phone is what makes our smartphones so good. However, there may be a few that are resulting in rapid Android OS battery drain., without you even knowing about it.
Try These
Stay in Power Saving Mode
Reduce Display light
Try using the App Greenify, helps you identify which apps are causing battery drain, and put these into hibernation when you are not using them, to stop them from lagging your device and leeching the battery

high idle battery drain

So coming from a LG v30 to this I been experiencing high battery drain when leaving the phone idle (screen off) at night. I had left it at 24% and woke up with it having 7%. Anyone else having this issue. On the v30 I could leave it at 5% and it'll hold that charge until the next morning. Any ideas
You may have an app preventing deep sleep I left mine on the other night and only lost a few percent overnight

Checked and says system was drain 24% since I slept
No idle drain issues for me. Started at 80% BTW. Must be an app or something on your end.
Are you rooted? I noticed Google News will occupy a lot of my battery even without using it. I've uninstalled it and have been okay ever since. Thing is a beast with battery.
To me it has to be an app issue. I can't believe how great my standby life has been so far.

Would definitely recommend a factory reset. Rogue app maybe? I'm surprised to have someone run into this issue. Hope you can get it squared off and get the full battery potential of the device. Nice to see you here from the v30 forums! ?

Wasn't trying to do that but why not, not like I haven't done this plenty of times with the v30(rom switching) ?
