Dear fellow enthusiasts,
since a couple of days, I'm experiencing sudden device crashes when I'm using it for network related activities, mostly over the 3G network (for example, I'm typing out a message on the Facebook app, and the phone goes into boot loop or simply "shuts down"). I had only recently upgraded to the 4th beta build for the Cyanogenmod 9, hosted here on XDA , so I suspected it would be related to this. However, upon reinstalling both the previous version and the new mod from absolute scratch, the issues remained the same.
I had noticed that after each crash, the battery charge displayed as very low (2-6%), whereas I'm certain the charge should be much higher. So I thought it might be some sort of corrupt battery-cache issue or something.
However, and here's my actual question, I just now noticed that my I9001 battery is slightly bulged, on both ends. This bulge starts just above the white printed SAMSUNG lettering, and it ends just bellow the QR code. I can't for the life of me remember if or not this is normal, so could someone please confirm this for me?
And while we're at it, could a faulty battery affect my performance as such (making my phone crash etc)?
Thank you very much in advance for any help or information anyone could give me.
I confirm, battery is slightly bulged in those places but it looks like a production "thing" to me (I hope I understood what you mean), no need to worry, I guess. Looks like corrupted battery stats, try to wipe it via recovery (phone fully charged, plugged in - then wipe battery stats). After that, i recommend one or two full battery discharge - charge cycles. I've noticed hovever, that after each full factory reset I have for about 20% better battery drain, than after flashing many ROMs, kernels and updates (cache and dalvik cache wipe only), my battery drain is getting pretty annoying. Try a full factory reset, if wiping battery stats didn't work.

Thanks a lot for the confirmation Jacol !
Anyone else who can confirm a bulging of the 1650mAh battery for the I9001? I'd like a large enough sample group if possible.
also happened to me
solved this problem by buying another battery...

Thanks Blumdum, do you mean you also had your phone crash on you?
yes
i charged the battery
after some time my phone turned off
i restarted it and i had only 2% battery left
then i took a look on the battery stats and there was a huge drop from like 95% to 2%

Hey people,
I received my new battery last night, I went for an Akku Powercell of 1800mAh. Charged overnight, been using it all day, no problems whatsoever to be found.
Thanks again for the assistance!
Swollen battery = defective!
I'm sorry but I've encountered this as well in the past. Normally working phone with sudden shut downs and huge drops in battery charge. It took me a long time to convince me that the battery was defective. So maybe this would save you guys some time in finding this out!

Hey, try to use cm10 for a few days, if the problem gone then your battery is alright, and please stop using beta roms, regret are so buggy and slow: )

In general healthy batteries DO NOT swell. Buy a new one before it explodes or starts leaking...
Hey all, just because people keep on posting, the battery was indeed defective, the roms were absolutely fine and the new battery is performing marvellously!
Thanks again for all the input !

I have the exact same problem with my sgs i9000-gt.
My phone turn off itself ( no restarts, its a complete shutdown ).
First, I thought i might be a problem of GB 2.3.6 rom i was using, so i updated to latest cm10 but the problem persists.
If you restart the phone after the shutdown than i shuts down within a minute again.
Also the battery drain is pretty fast. I notice the same bulges on the battery as reported in this post.
I did the battery calibration thing as some people suggested, but that does not solves the problem. However, it got rid of the fast changes in battery status which was happening before. Like when you restart after shutdown at 80% battery status, it will show like 2% battery left and after few minutes of charging it would boost back to 80-90%.
But still the battery drain is pretty fast. It discharges from 98% (i cannot get to 100% charge, 98% is highest) to 50 % within an hour, just idling.
And when i am around 40% or so and if i recieve some message and try to open a app it shuts down again.
I have ordered a new battery just in case. Will update here if that improves things for me. But i will still like advice on which is a more economical kernel and rom for i9000-gt? Some people suggested slim bean + semaphore on some forums but i would like to have some more concrete advice before i change more things without knowing the source of the problem. I would be grateful if someone can suggest what is best to use with some details( version, etc). Thanks for that in advance.
I thank you all (users + developers) for all the useful information provided on this forum, i learnt a lot although i still am not able to fix my problem . And I hope someone might come up with a concrete solution for this problem. If there is a solution which I might have missed, I thank you in advance again and hope you will be kind enough to point me in the right direction.
cheers
update: the phone stays alright if u dont do anything on it, but the moment you being doing something on it other than playing with system settings, like run some app, especially something that uses network / wifi, it shuts down. none of this happens though while its plugged in. it happens only when its on battery.
problems fixed so far after replacing the battery

I flashed back to stock samsung rom ( from the value pack) and the problem persisted.
today my new battery arrived and all the forementioned problem seems to be gone with the new battery, my phone seems to be working fine for last 5 hrs without any restarts or crazy battery drain. will test the same with custom roms again. As of now it only seems that problem was the battery.
Cheers.
thanks to the forum and developers
is anyone here who has a battery problem, like phone sometimes shuts down in between 25-32% due to low battery and then charges from 0%, and still shows charging at 100%?
Yes so many time happened to me shutting down at 20-25%.and I went to service centre and they didn't resolve my issue.after that me my self flashed the official miui ROM and locked the boot loader.after many days my issue solved
thank you for sharing your experience, I will try if have similar problems like you
I too faced the exact issue last month. What i did after little research is i charged the battery to 100% and while plugged in deleted three files from twrp/file manager under data/system namely batterystats.bin, batterystats-daily.xml & batterystats-checkin.bin.
Then reboot and unplug and you wont face the shutdown issue. The battery will be used till the very last percent as it should be.
I'm still having this problem after trying a lot of things. Could you resolve it?
Just do what dedycx said and should be fine .
dedycx didn't said anything. If you are talking about the batterystats.bin file that's not doing anything. The only thing left for me to try is MIUI D:
It was a Issue for me on RR.. even after 3-4 times of calibration... Now I moved to oreo ROMS and flashed 3-4 Oreo ROMs and never faced this issue.. moreover my battery was not going over 96% now I check it on Liquid Remix and Voila! Its 100% now.
Hi guys...Here's my problem. It may be a coincidence but after I updated to 8.7.5 my phone now randomly shuts down , I think, when it tries to go to deep sleep, and I cannot make it boot up unless I disconnect the battery. I can use it the whole day without any issues but if I leave for an hour without touching it will shutdown and will not boot up again. After disconnecting the battery and booting up again I researched the battery use and it seems that prior to shutting down there is a huge battery leak as the phone loses 20% of the battery in a matter of minutes with the screen off and afterwards shutdown. I tried different ROMs now and still nothing ..went back to stock and still the same. I'm suspecting now that it might be hardware related but why am I able to use the phone without problems and the issue comes up only after a prolonged time of being idle. I'm tech savvy and like to try all kind of solutions but now I'm at a dead end....don't know what else to try. Any help would be greatly appreciated
Try firmware MIUI_8524 as I think this one is really stable. Cross checking via Kernel Adiutor (ROOT) might be a good idea for your case . You could prevent phone going into deep sleep to check if there is still an issue.

I received my Xiaomi Mi 9 yesterday and after setting everything up I started to notice a fast battery drain, even when the screen is off, which I found to be quite weird for this phone.
When I restarted the device however, my battery percentage was back up again. It somehow went from being at 15% to being back at 73% after the reboot!
I am very confused about this, and I have no clue what could be causing this.
So far I've tried to do a factory reset, which didn't seem to help however. I've turned off WiFi, GPS, Sync and I pulled out my SIM Card and left it sitting, screen off, with occasional checks, but still the same drain.
What's even weirder about this is that the drain seems to be constant. I included a screenshot of the battery history graph, where it is visible that the battery "drains" at the same exact speed every time. Every time you see a spike upwards, that is me rebooting the phone. You can also see that WiFi (and also GPS and SIM Card) was turned off at some point, but that didn't affect the drain at all.
The phone isn't running hot or anything either, it's literally doing nothing, just sitting there draining.
I've let it drain down to 0%, at which point it just turned off. I could immediately start it again and it was back at 66%.
MIUI's battery analyzer thingy does also not have any recommendations as to what to do, except "turn on battery saver", which it says only gains 8 minutes.
I'm running the latest update that I could get through the updater in the settings (MIUI Global 10.2.17.0).
I'm really at a loss here as to how to fix this, or even pinpoint what could be causing this. I would've blamed I faulty battery in my unit, but it kind of seems to be more of a software issue? I really don't know.
It seems that a hardware fault (BSI) rather than a software issue
Cause no one report such a problem with this phone
Do you have any idea which part of the hardware could be causing this?
I said bsi or battery
But refer to warranty for replacement

I have a T713 on Android 7. Once the battery level is below about 80%, the tablet will often crash into a bootloop when switching between screens/apps (not while using one app).
When the battery is below 45% it will always crash as above (e.g. wake the tablet to home screen, see that battery is 45%, launch an app = bootloop).
The only way to stop the bootloop is to plug in the tablet. On mains power, the tablet doesn't crash.
I've done a factory reset, wiped cache (after using it a while, of course), tried Safe Mode. Makes no difference. The crash is always reproducible below 45% battery. Battery charge logging does not show any sudden drop in battery reading immediately before/at/after the crash.
The Accubattery app says the battery is at 82% health.
There are reports of similar phenomena in other threads and sites, usually attributed to the battery, but I am sceptical that this is the issue because there is little evidence that people actually solve it by replacing the battery (and the symptoms don't seem to support the basic assumption that there is a loss of power). Any experiences/ideas?

Have you reinstalled the factory image with Odin? That would be the logical place to start.

Thanks for your suggestion. The device is currently stock, unrooted. Could you tell me why using a factory image could help? (The last official update to firmware on the device was a long time before this problem appeared in March this year.)

Like any device, who knows what has managed to get jumbled up in the image. Security patches and other updates can only overwrite so much since they are doing in place updates. Even a factory reset has to be pulling the image from the device itself where a factory image is completely clean. I know it is a PITA to set a device up again, but the fact that you can do the system stuff before installing any apps or files or anything and then see if the problem shows up immediately after imaging. If so, then you pretty much have narrowed it down to at least a hardware problem and you have less places to look (the battery for example). The last time I flashed the stock image a month or so ago, it took a security updated Feb 2019 (maybe) before I rooted and such putting it in the "modified OS" world where it will not get updates again until I flash stock again. The last actual OS update might have been around the end of 2017 beginning of 2018. Too bad since the device can clearly run builds past Nugat and has never been deprecated.

Thanks for the extra info! I'll look into doing that.
A preliminary update, in case anyone visits this thread before I finish thorough testing:
The cause is emphatically NOT the battery. After reflashing firmware and then doing a factory reset, as sliding_billy suggested above, I am unable to reproduce the problem. The tablet appears to be working fine in its current fresh state, even running on low battery power. I'm now planning to gradually reinstall apps and system updates (if any) and continue testing.

Glad that at least the initial solution is working. We'll see as you reinstall apps and complete any settings if it really was that "simple."
