Hi guys, recently I noticed my battery was going down faster than before just suddenly, it is draining like 40% in 3-4 hours with the phone just playing Spotify screen off and basic email or messages use, with a full charge I barely get 2 hours of SOT. It started a few weeks ago I was on stock rom, rooted, for months, so I flashed another custom rom thinking it will fix it but it happened again. I tested 4 or 5 roms and issue still there. I really don't know how to fix it I already Factory reset multiple times.
Does somebody have an idea of what's causing this ? Thanks for taking time to read this
(Exynos S8+)

Hello,
I got my (Verizon) Samsung Galaxy S3 two days ago, and rooted and flashed it with the CM 10 Nightly builds after a couple of hours of using touchwiz. Everyone has been saying that they are getting more out of their battery with CM 10, but my experience hasn't been too good. I am getting maybe 9 hours of battery with normal use. When I got the phone I run it down to 10%, turned it off and then charged it back to 100%.
I have turned off 4gb (as I don;t have no real 4g signal around me), have the display on the lowest setting and have even under clocked it to 1.2ghz and it's still draining fast.
I have been reading through some forum threads and there are people with the same issue as me, some say they think it’s a faulty battery so they ordered a new battery but never post back there results.
Others say that doing a reset of the phone/reflashing CM 10 does the trick.
I have also experience my phone getting warm to the touch when just checking facebook or web browsing. My phone core seems to be running at 90-95 Fahrenheit when it feels warm and have never seen it go above 100.
I’m open to resetting my phone, but as I have just set up everything, I would rather not to.
I know this is a lot of information, but any advice at all would be greatly appreciated.
Thanks in advance.

a few things.
if youre running a launcher some allow you to backup your homescreen settings, even the free versions
i have never gotten that bad of battery life out of a CM10 rom. Your screen on time is a more reliable idicator of your battery health than hours of use. the hours of use statistic is easy to manipulate
run better battery stats to find any wakelocks you may have to see whats eating your battery.
Re
Thanks for the quick reply!
I'm not sure it's an app that's causing this, as I didn't install anything on the phone once I rooted it for a couple of hours and it was still draining fast.
I have gotten the betterbatterystats app and will post what I find out.
I am also not getting the best battery life. I am on paranoidroid 2.52. I had the phone fully charged, screen on watching a video in skyfire. I did not make 3 hours. Is this what others are getting?
Battery issue
You probably all know this already but the screen brightness level also effects the battery a lot. I set mine to auto.
I'm wondering if you flashed your radio and rpm to the latest leaked jb
Hello everyone,
when i upgraded my phone to this rom, the power was working fine and normal.
Recently the power decreases from 100% to 35% in two minutes, which is weird and it takes forever to charge. I have ordered a new battery to test, but i was wondering if it was a software issue?
PAC version, 22.1.1
Android version 4.2.2
Thank you in advance
Install bbs and check no apps are draining your battery, turn your phone off to charge it a couple of times. You should be able to have a basic log to look through after a couple of hours, Let bbs run through a couple of charge /discharge cycles before looking deeper into the logs. I do suspect it's your battery though.
Jokes gets more serious thought, than serious words these days
Try a Sense ROM, I noticed the same problem on all AOSP-based ROMs I tried.
thanks for the replies, yeah i think it was the battery. got a new one.
changed rom to the desire xs
but prefer the previous one.
Hi all!
i got a oneplus one since about a week but i'm facing a serious battery drain problem. I bought my phone used with 5 months of life and used only a few times so its conditions are like brand new. When i first got the phone i installed cm12.1 nightlies but two or three days ago i switched to the last version of cm12s. Anyway, in both cases i have the same problem:
When i use the phone with the screen on the battery level lowers so fast, about 1% per 1 minute and half. During sleep instead drain seems to be normal. I don't have so much app installed and i usually take blocked with servicely or greenify the ones with services that i don't use often. Also have auto brightness to medium levels and i do normal use (generally navigation on chrome since this morning, no games at all).
Anyway, plugged off this morning at 9:00, now at 14:00 i have 20% of charge with 1 hour and 35 minutes of SOT.
The old owner told me that he didn't use the phone for about 2 months before selling it, so i'm trying to recalibrate the battery (discharge until it turns off, then charge to 100% with phone turned off), but situation doesn't seems to get better. Do you know if it is a well known problem or it is an hardware fault? Can you help me?
Thank you in advance and sorry if my english is not perfect

Have you tried other custom rom? What about stock ROM? If all ROM gives you similar issues, how about your firmware? Is it up to date? If all this doesn't work, you might have a faulty battery :silly:
Hi Bobbi, thank you for your answer! I tried cm12.1 nightlies for one or two days before and I had similar problems. Isn't the cyanogen 12s actually the stock rom for this phone? And what you mean with updating the firmware? I have downloaded cm12s here in xda, wiped all and then flashed it, isn't in this way all up to date?

CM12s and OxygenOS are both considered the stock ROM of this device (I guess ) but some others (like mine) comes shipped with ColorOS as the stock rom
But nonetheless and that aside, flashing CM12s and updating the firmware is a bit different. Most ROM doesn't pack with firmware except for OxygenOS and CM12.1 nightlies
Has anyone noticed their battery getting incredibly worse over time? I bought my S7 on release (non edge). And since then, I've noticed that it doesn't last no where near as long. Today, for example I started my day at 7:00am when the battery was 100%. As of 30 minutes ago, the battery reached critically low (5%). From 7am all I did was watch a few videos, facebook, snapchat and then play music. But all the above for not too long.
I've also noticed that once the phone hits the 15% battery (I know due to the notification), that within minutes the battery can be done to 10% or so, without touching it.
I'm more so tempted just to take it back, unless there's an easy fix OR it's a known issue with the current version.
Thanks!

I've definitely noticed this since rooting. Maybe it has something to do with that? Like a ROM you flashed or what not? I'd like some suggestions here as well.
Thanks!

I haven't rooted the S7, it was the first phone that I've left stock from opening.
What does the battery stats say is using the most mAh?
Facebook app is a known battery hog
Obviously over time, you'll install different things, and slowly the phone will start using more and more power running background apps
A backup and Factory reset will show if there is a hardware / battery issue, or if it's purely from stuff you've installed over time
Also clearing the caches from recovery could help
yeah ive noticed this too. My usage habits havent changed but my battery life is almost half of what it was when i just got the phone.

Cache has been cleared from recovery, and I don't generally install many apps so since I've bought the phone the apps have stayed the same.
Android system is always on top. Unless of course I spend hours on Facebook.
Might have to factory reset. I've used my phone with the same apps and time since I've bought it, and I'm finding I'm charging it 3x as much.
I think it's a root issue - deep sleep.
After S6 Edge Plus, when you root a samsung phone, it won't go in deep sleep. I believe there's a fix for that.
Have you checked the battery usage stats? It gives you the breakdown on what apps are eating up the battery.
I have had my S7 for about a month and battery is about the same.
Just to update this thread for those that may have a similar issue...the other day I couldn't live with the battery life the way it was. The phone used 50% in several hours where I barely used it.
Decided to completely re-flash with stock (was stock before) as opposed to simply wiping all data. A week in, and the phone's battery life is back to the way it was. I went to bed when it was on 100% (as a test) and woke up 7 hours later with the phone on 94%, with wifi, location and bluetooth on.
Not sure what had caused it to use so much battery previously, but it's back to what it should be and that's all that matters.
hi with my s7 exynos i do 3h screen. i think there is a problem. i bought my s7 one week ago. can anyone help me?
Rooting and installing custom kernels when done right should greatly increase the battery life of your device. This is a well known guide here on XDA for improving battery life for our devices.
That being said, Lithium Ion Batteries hold less charge the more cycles they are put through, its a given fact but as you said your device is relatively new and therefore should not be experiencing this kind of problem. The way I see this is there are 3 possibilities which may be causing the said problem...
1) You have rooted the device and done some modification/s. ( which you haven't done )
2) Your battery is being drained by a service ( Like Oculus or VR ) in fact a number of reddit users complained their S7 was overheating and battery was draining really fast for some reason. Check This page out, It might help you.
3) Battery Defect, you must've gotten a "bad" model, if you haven't tripped KNOX you could try bringing your phone to Samsung and see if they would fix or replace it.
Good luck
I think this has to due to them samsung updates. As far as i know samsung been always doing things like this where they made the OS slow as hell after a while so you gonna get a upgrade sooner but a battery should last 2 years minimal without degrading.

i get like 5 hours screen on time and bout 1 day standby time but i have most bloatware disabled with the package disabler. But if i was you i would contact samsung.
This happens with Samsung updates on every Galaxy phone. It's like a curse. It's unavoidable.

May i ask if the people with these problems use the fast charge? I hearing many bad things bout this so i switched it off and must say the normal charge isn't that slow and if it can keep the battery good for longer then we all should use this.
I turned fast charge off about a week after I got the phone, was making the phone and charger pretty hot for the sake of about 5-10 mins quicker charge
Pointless really, unless you are desperate, only have a few mins spare and need as much power as possible in that short time, and if that's the case, enable it for that one time
Restrict background data on all but the most important apps (phone, text, email), dave power all but the most important apps. Battery life is fine

So I liked my gear s3 but haven't worn it regularly in about 3 months. After the first update that destroyed battery life mine never recovered. I've fully reset it multiple times, and best I can get is about 8 hours on a charge with normal use even with the latest updates, and the same use I got 2.5 to 3 days out of before. So what's the solution?
