Hi All knowledgeable folks / @linusdan
Ok, so I've tried to re-build my dad's S2 (i9100P) which he has had for a couple of years. All appeared ok at first, although suffering battery drain recently... He tried a couple of batteries, as he has about 2 or 3 batteries lying around (as they are so cheap). Neither seemed to make much difference, so I said I would wipe the phone and start again. Whilst switching in and out of Recoveries, I noticed the battery go from like 93% to 80% to 60% to 20% to 13% in a very very short time. Equally strange when it was at its lowest, 13% and leaving it charging for a few minutes... say around 15 minutes, it then jumps up to like 70%.
So I switch the battery over for another one. I have a little play around with the phone, thought I'd try a new Android 9 / PIE rom and use Emulated Storage. However I thought this rom, as amazing as it is... would not be for my dad. I tried a couple of others out, and dropped him down to a Android 6 / Marshmallow rom. Purely based on speed, lean and fairly decent battery usage. I took the phone to the pub, played around and all seemed good. Stable, no crashing, but due to playing around... Thought I'd flash it again, and start a fresh.
However now...
Straight after flashing the rom, it will constantly reboot at the login screen. If I unlock the phone, then things like the default Launcher will crash, as will Google Music, Settings and File Manager. So I tried another rom, Nougat and Lollipop, and they both randomly crash too...
So I hooked it up to Odin, and used the STOCK partition (PIT) file and STOCK rom (Orange UK 4.1.2) and returned it back to FACTORY settings. Now all seems good again, battery seems to last a long time and had ZERO crashing since back to stock. However, so that he can use a Smartwatch I got him, he needs a minimum of KitKat on the phone....
However, why do you think the phone will be constantly crashing now ?? Has something died inside, and what could of died?? Why is it stable on stock and not on custom roms?? It used to be fine on customs before hand...?? Any idea's??
Model: i9100P
ROM: Resurrection Remix LP, MM, N, O... and Pixel PIE. Currently back to Resurrection Remix MM.
Partition: RePit, 2GB System, 6GB Data, rest to SDCard
Batteries: Tried a couple of batteries, still got a couple more could tried... all supposedly genuine...
Cheers, Lister

Hi guys,
Not sure what could be the issue. I'm quite a veteran when it comes to troubleshooting these phones and flashing, etc. I've been a power user since the S1 and S2.
I flashed CM9 a few weeks ago, one of the stables and it was all running fine. One day I picked up the phone after charging overnight and it was really hot, the battery drained in about an hour or so, the whole time it was extremely hot.
I flashed a few other CM roms, which didn't fix much, tried full wipes and everything.
I've now gone back to an original samsung rom which I flashed via odin. This seems to have fixed the overheating issue, however, my battery barely lasts more than 3 hours on full charge and this is with absolutely minimal use (few phone calls).
WiFI is also extremely unstable. It takes a while to connect to any network, and when it does, it'll drop after a few minutes. I've tried different networks.
Scanning for WIFI networks works fine, so does this rule out a faulty WIFI chip?
I'm thinking the battery drain may be related to the WIFI card.
I've also tried a new battery.
Any suggestions, or is the phone fried?
A number of posts saying the same .

No, to get up your hopes, the phone isn't dead, yet.
Try flahsing a ROM, other than CM. I have the same problem, with AOSP, that's why I stick to sammy based ROMs, AOSP is made for the device, but Google only tunes it up to their standards, when it has something to do with their Nexus devices.
I'd say: Try a different ROM, don't overclock it. If that doesn't work, flash stock and then try it. One of the two should work, though!
I've gone back to a stock Samsung 4.0.1 rom. Flahed using odin, yet still the same issue with battery life and WIFI.
I've heard somewhere that flashing CM9 can cause WIFI issues, and there's a specific flash procedure to get it working normal again?

There is no 4.0.1 for the S3. I'm just sayin'.

My bad, I mean whichever came with the phone.
My edge had decent to great battery life in the first 2 weeks of my ownership, however on the third week now, and suddenly the battery runs out much quicker (didn't download much new apps).
And after a few test, I found that Android OS is always the top or second most battery used application.
Seems like a lot of people have this problem across all android devices, however after a bit of research I still can't find the cause of the problem.
So what are the current solution for this problem, I have disable pretty much everything (everything google except map and play store + most samsung app + more)
1. If I root my device and run Stock kernel and Rom would be help with the android OS battery drain or do I need to install special program like greenify
2. Would factory resetting help without rooting?
Thanks guys
They are supposed to be releasing a new firmware that deals with this issue but it seems to be taking a very long time.
I too have the problem and am fed up with it.
I have the same problem..
Since having my edge for a few weeks now, I have had about three lockups and two occasions when the phone rebooted by itself.
I did a factory reset as soon as I got it and there have been no firmware updates since doing that.
Hi! I've been reading this forum on and off for few years, but never actually posted. Hope someone here can help me sort out my issue, thanks in advance!
Basically, I've flashed a cm13 via custom recovery on my second phone - Xiaomi Mi4, and I'm having all sorts of issues with it. I bought the phone in China, and for a while
used the stock MIUI interface, but I hated all the bloated apps and weird pop-up advertising, so decided to flash. it was the first time i've attempted it, so it took some
time to figure it out
My two main issues with cm13:
1. It crashes and restarts two/three times daily for me. I mean, I've cleared cache, I basically have no apps on the phone (apart from few messaging apps and facebook).
Is it just because it's an early cm13 build, or it's a nature of custom roms? I'm wondering if switching to a snapshot cm12 build would be better? I don't really care for
android 6 features on this phone that much, I just want a stable experience.
2. The charging became uber slow, painfully so. On MIUI it'd charge to 100% in about 3 hours or so. On cm13 it takes 3-4 hours to get to 30-40%! Never seen anything like
this. Also, if the battery depletes to 0%, the phone wouldn't turn on, even plugged in for charging. It'd turn on after an hour or two into the charging process. Seems weird,
as every other android phone I've owned previously would turn on even with 0% battery if I'm plugged in.
Anyone else experience any of the listed issues? Is it just an early build, or I've done something wrong in the flashing process? I really just want a stable simple os, no advanced
features or whatever, just need it to work
Thanks!
I have been using latest nightly.. No issues no reboot.. Charging time is 3hr

Thanks for reply! Would you mind telling me which gaps you've used for your build? I remember I had some sort of an issue with few gaps
I tried, I think only the smallest package worked for me. Maybe that's the issue and something in the gaps i've installed freezing/rebooting my os?
Thanks
A few months ago, I flashed a 6.0.1 cyanogenmod rom(by Alberto96) onto my jfltexx(international) S4. Excellent Rom I must say, but since that flashing, my phone had been dying at 30%, (when I switch on the screen if its 30% or below it'd freeze then switch off). Thinking the ROM was the issue, I then reverted back to stock Samsung 5.0.1, but the issue persisted. I'm not a fan of the stock rom and would like to go back to CM or lineage, any idea what could be causing it?
I've eliminated the fact that it's a faulty battery because this is a new battery, and all my other spares that switch off at 30% work just fine on other devices.
Really hope you can help me resolve this.
Regards
Hi there,
I purcharsed a Pocophone F1 two months ago and, after unlocking bootloader, I ran into serious battery issues with the phone only not lasting a day when in the same usage it used to last about three days before. So I came back to the shop and they exchanged me with another one after two months (because they first attempted to understand the issue but finally lost the phone).
So, when I got this new phone, like for the previous one, I found the battery life amazing. Then I unlocked the bootloader and flashed Magisk, and it suddenly dropped : I was losing about 1% of battery every 2 minutes.
So I re-flashed the stock ROM, without Magisk or anything, but the problem didn't disappear. I finally wiped everything, flashed the stock ROM, relocked bootloader (which wiped a second time the data), but the problem was still here.
Currently, I'm running the Havoc 2 ROM (Android Pie) flashed with Open Gapps and Magisk, usingSphinx Kernel. It worked great at the beginning of the day, but for no apparent reason my problem appeared again a few hours ago. I attached a few screenshots to illustrate it :
The first one is when going into a terminal and typing `su` then `top` while I was listening to music on Google Play Music (there was no other application opened, no WiFi, no Bluetooth, no GPS, brightness at, let's say, 50%). As you can see I was even in power save mode. I also tried to use other CPU governors like `blu_schedutil`or `powersave` but that didn't change anything (the default and current one is `schedutil` for both big and LITTLE cores).
NOTE: Don't mind about the usage percent and time, I used the "reset" button to check what was going on.
The second one is the result of Kernel Adiutor in the same context, and the last screenshot is when I have only this application opened (no terminal, no Google Play Music). Because of this, the Pocophone heats up, of course.
Also note this problem can happen randomly ; for instance I just re-launched Google Play Music and played some tracks, the big cores remained at near to zero usage percent (while the 8th core was still as its maximum).
To sum up what I tried:
* Changing ROM doesn't help ;
* Using a custom kernel doesn't help ;
* Re-locking the bootloader doesn't help ;
* Wiping everything in TWRP (internal storage, vendor, data, etc.) doesn't help ;
* Going in power save mode doesn't help ;
* Setting the CPU governor on "powersave" or other doesn't help ;
* Closing all other apps doesn't help
Does anyone have an idea of what's going on? The same problem happened with two different phones, which is very strange ; I don't have any background application running (I manually stopped them all, and the problem was here even after flashing the stock ROM alone, with no non-stock application installed).
Thanks in advance for your help
Try going back to full stock stable with stock recovery via fastboot method. Drain battery to 0 and full charge.
Are you having good cell reception all the time?
I already tried this and this changed nothing. And yes, I had good cell reception all the time.
Because of some posts I finally found when looking for my apps, I found Google Play Music was eating battery on some random devices (sometimes it can drain battery at an amazing rate on several different devices, but no one knows why). The battery life seems better know. Still, this doesn't explain why I was experiencing the same problem with the stock ROM with stock recovery, without this application or any other.
The phone is brand new? If not, have you checked the health status of the battery?
I got mine second hand from aguy at work and it seemed OK on stock MIUI, but I noticed much faster drain on Lineage OS although everybody saying is one of the best for battery life, finally has seemed to get better.
I am using Havoc with pico GApps, D8G kernel (no oc) and FDE.AI(paid). My idle times are much better, and overall use too, the performance in games is much better too, but I've opted for some over clocking to boost gaming so the drain on heavier loads is greater as expected.
