Nexus 9 battery meter glitching + poll - Nexus 9 Q&A, Help & Troubleshooting

Hello fellow Nexus 9 owners! I've got a question for you. I've had my Nexus 9 for 3 days now, I've been very satisfied with what this thing can do in terms of performance and even battery life, mostly. Now I am facing a problem. Today, I used it just normally playing World Of T
Goo and suddenly, it died on me. No warning, nothing. The screen glitched out and looked like a failing Linux graphics driver (weird green/black/pink/white pattern), the speakers were outputting a strange noise for about 4 seconds and then the screen went black. Pressing the power button didn't do anything, so I plugged it in and the white LED flashed just as if the battery was totally empty. So it charged up for a while just as always, took about 15 minutes and the charging monitor showed me 3% by the time it had enough power to load it up (that was a few hours ago). The battery is now on 16%, I plugged it in and suddenly, it displayed 21% (while the device was turned on, not the battery metre mode or what's it called). So I'd like to ask you if you have experienced something like that with your device or if it's just my unit. I hope this glitch isn't caused by CM12. My device is also charging very slowly or not at all during use. It either stays at, let's say 15%, or drains slowly. I wonder if this can be fixed with a custom kernel that supports quick charging.

Oh, brilliant, thanks. That was quick. So is there any workaround? Pretty annoying to never know how much you actually have left.

What about the slow/no charging issue? Is that CM related, too?

Yep, everything is related. Actually, it charges normally, just that the battery % updates only when you replug. The only current workaround I found is go back to stock/not cm-based rom.

And what about the percentage going down during charging? I've had a similar problem on my Nexus 5 once, the solution was to use a better cable and a better charger. But here, the percentage goes down although I am using the stock charger+cables.

Probably cm related too. I'd just flash rastapop or some other rom until nightlies get sorted out. Nexus 9 received them less than a week ago so bugs like this are normal.

[Q] Telus fascinate serious battery drain HELP!!!!!

Ive noticed serious battery drain since I first bought this fascinate from telus. On 2.1it lasted around 11 hours. Since upgrading to 2.2 leak, id say 8 hoirs max with only approx 1 hour of uusage and the rest on standby. I turned of sync, auto brightnrss and turned brightndss as.low as possible. I make sure no apps r running in the background. Yet it still dies superfast. Is this a issue with my battery thr phone itself or firmware or kernal. Its been a week of trying to find the problem so any help would b greatly appreciated. At tgis time im running 2.2 leak with all the files it came with and no root. Thx in advNce
And hour and 12 minutes with about 30 min of internwt surfing and im down to 80 percent WTF
I update OTA last week on Verizon to Froyo 2.2. My battery was overheating and draining like crazy from my CPU usage being at a constant 99%..
I found the source of the problem. An app I use for facebook called "FLOW". The CPU usage was cut to 20% when I killed it with "Advanced Task Killer".
I resolved the issue by: Opening Flow.. going to Preferences.. Notification Settings.. Refresh Type.. Checked Periodic Polling (I was using Gmail Experimental previously)
Hope this helps...

sounds about average for a fascinate....
I'm on telus as well and also have terrible battery life, I've found no fix other than completely turning off Data using the toggle when holding the power button. Flashing a new rom might fix this but I've been to scared to since I bricked a phone trying it the first time. Hopefully when/if ever we get a 2.3 update it fixes this
Does anyone know where one can get an extended battery for this? I picked one up but it's for the friggin Verizon US version, and the battery cover isn't compatible, even though the battery fits(camera doesn't align, speaker's not even close).
Seriously, the American counterpart's accessories have been my biggest frustration with this phone, next to battery life...
Thought I'd give this a bump. The battery life on this Telus Fascinate 4G is truly disappointing and jumping through hoops trying to find and kill apps and services with and without utilities is wasting far too much of my time.
Anybody get a good handle on this?
Bump for same problem.
Samsung Fascinate SCH-i500 Verizon
Running unmodified and unrooted. The phone itself works perfect. No problems other than the phone seriously eats battery. Yes the battery is still good and nothing wrong with it. Plugged in it charges super slowly. And the screen itself takes more than it provides. So i did the following.
A. Changed battery to a known working one.
B. Check with car charger and a home charger. As well as official samsung charger.
C. Gave a ROM a try. Running Dirty Unicorn. Lowered cpu to 800 max and 100 min.
D. Turned display to 50% Brightness.
My only try now is to try a different kernel or something. Im also thinking that the display itself is the culprit somehow eating to much voltage.
Or the gpu. The phones operating temps are good.
I have another post here http://forum.xda-developers.com/showthread.php?t=2430393 relating to where i have a USB problem and need help figuring it out. There has not been any replies. So i am taking upon myself to learn more. Ive worked with 3 Droid Milestones. Hopefully these two i500s will not be to hard. I need help on this new i500 to see if its not the motherboard. The charging port is on the motherboard and if this replacement eats batteries , then the point would be mute to use it for a working USB. A conundrum.
Do i try a different kernel or somthing else. Whats my next step.. Please help.

what else do you have running?
what is the battery life overall usage? and screen usage hours?
screen is always gonna be the highest consumer of your battery
50% still pretty high unless you are out in sunlight, I keep mine between 0 and 30 % unless in sunlight
you can try running the greenify app from playstore.
what king of life are you expecting to get? anywhere between 6hrs to 24 hours total phone battery life is about average depending on how heavy user or how much in standby mode.

Its been on the charger since i posted. its only at 56%
3h 25m left
Screen 55%
Cell Standby 9%
SystemUI 7%
com.maxmpz.audioplayer 7%
Android System 7%
Its defiantly got something wrong as even though it says 56% if I unplug it, it will die in about 10 min. Even with a fully charged battery it does the same. Yes i also waited until 100% and wiped batt stats and at 3% left wiped stats. Screen is in standby

I would recommend going here
[APP][2.1+][16 Apr. - V1.13.4] BetterBatteryStats
you can get better logs and information, plus if something is not easily visible to what is causing problems you can post up a log file for them to look at.

I had installed the program and it didn't really show anything abnormal. Although after installing the Bat Meter, when i shutdown it killed the phone till i ODIN. So tried on the other phone as well. Same thing. Install it and compared notes. Reboot phone and had to ODIN. So maybe bad app? Well whatever. I didn't see anything unusual. Although I did notice something strange about the phone that's bad with charging. I already eliminated the battery as the problem as well as charger. But the phone that is eating battery faster than it can charge, it gets warmer at idle than the other phone. It charged just super super tiny faster than the battery eats using just idle display on lock-screen. As well this phone also with a fully charged battery will read 100% But after about 21 minutes of poweramp at 33% volume on headphones will read about 52%. Then sitting rest at idle no display from 52% down to about 14% popup around another 5 min. Then completely dead in about 3 minutes. And the phone is pretty warm. Today it was ambient temp of around 87* outside and sitting in shade and it was hot enough that it wasn't comfortable on my cheek for more than 20 seconds. Half the time the temps are normal. Now remember I'm not running overclock and actually under clocked to 800. Ive tried 3 different roms with diff kernels and same. Could it possibly be a bad heat-sink? And the extra heat is killing battery?
[Q] Battery Drain
I recently was given a Fascinate and am having similar problems. I was told the phone had a bad battery, so I ordered a replacement. Once I got the new battery in, I flashed the phone with the Carbon ROM [the phone was unlocked, but running the OTA 2.3.5 I believe]. Everything seemed to be working fine the first week or two, but now there appears to be a serious battery drain or leak after I power the phone down. I can charge the phone to 100%, power it on and use it for a period of time, then power it down with 90% or more battery life, but when I turn the phone back on, the battery will either be really low, or completely dead, where the phone won't respond at all until I plug the charger back in.
I reflashed the phone with an AOKP ROM to see if that'd make a difference, but it didn't. I tried using the first battery and the drain/leak still persists. The commonality between the two roms is the Devil kernel, so I'm going to flash a different ROM with a different kernel to see if that makes a difference. I also installed the app mentioned above to log the battery stats/usage to see if anything stands out there.
Has anyone experienced something similiar - the Fascinate consuming battery life while powered off?
Yeah the power off leak does seem to exist.
Can't remember the cause though.
I've not tried to really confirm,, but try popping the battery out then back in after you have powered off,,, then check after it has sat overnight to see if drain still exist..
Mine i just always leave on a charger overnight.
.
[Q]
Thanks for the reply. I'll try that. I've left the phone on today, just put it to sleep during periods of inactivity, and the battery is currently at 75% with occasional mild use after 8+ hours "on".
[edit 11-29-13]
After almost two weeks of use, I can confirm that if I power the phone down and do nothing else, the battery will continue to drain to 0%. If I power the phone down then remove and replace the battery, it's fine. It's an extra step, but it works. Thanks again.

My Android OS battery drain fix

Hey guys.
It seems like almost everyone with battery drain issues has Android OS at the top of their battery stats.
I just want to share my experiences with this particular Bug.
Maybe it will help anyone. Please share if it also helped with your problem.
I had the Android OS bug since I dropped my phone a few months ago and had the screen replaced. The guy who replaced it (official Vodafone shop employee) said that they didn't just replace the screen and that something else was also damaged (they didn't say what) so they also replaced the rest. Well, that's when the Android OS problems started. I tried many ROMs and many Kernels. Sometimes the problem went away for an hour or so, but it always came back.
Then I finally decided to use BetterBatteryStats two days ago (I really should have done this earlier, I know...). I came to the conclusion that I had some sort of the well-known "fuel_alerted" bug, since fuel_alerted was the service that kept my phone from going into Deep Sleep.
This bug should have been fixed long ago but for me it somehow still persists, even on stock JB.
It didn't only drain a lot of battery (I had 8-10h maximum without doing much), it also used up a lot of CPU time, effectively slowing down the whole system to the point that I wasn't able to use Spotify on my phone without severe stuttering.
Well. I found a solution to the fuel_alerted bug.
The procedure is: turning airplane mode on, shutting phone off, taking out battery, putting it back in after a few minutes, turning phone back on.
This solved the problem. No more Android OS draining the power. Phone goes into Deep Sleep again. Only 2% drain after an hour. Spotify runs smoothly again. Yeah!
BUT well... It seems like the problem comes back randomly for me, today I had to replace the battery 5 times...
Now I am trying to strictly follow another "rule" to keep the problem from coming back: Always waking and unlocking the phone before plugging it in or out of power. I never did this before so it could have been the cause of the bug. Now let's see how long it stays bug-free.
If it still doesn't help, I guess I have to conclude it's some kind of hardware problem, which could only be solved by Samsung...
EDIT: Nope. Problem still there. So not really a fix, but maybe still helpful for somebody.
Okay, what ROM are you on?

It's the up-to-date stock Samsung ROM I guess. See attachment for infos.
Damn, it seems like the problem just came back without me doing much. I only checked BetterBatteryStats every 30 minutes or so and recieved 1 SMS just a minute ago. Seems like the bug started 20 minutes ago, when battery was around 78%. Now it's draining battery like hell again, Spotify stutters, Deep Sleep won't work...
Guess I'll have to pull the battery again.
Since I'm pretty new to all this: What kind of information would be useful to narrow down the source of the problem?
I can provide my BetterBatteryStats screenshots and logcat/dmesg files as well as my Android Battery Stats screenshots.
Is there anything else I could post?
Yeah, screen shots of partial and kernel wakelocks.
Sent from the little guy
I just rebooted the phone, waited for a few minutes and took screenshots.
Here they are.
Okay, this is what you need to do now, drain it empty, charge it (while phone off) till 100 %. Remove the battery, wait for 90 sec or so, put it back and power on.
It's a placebo, but it might work.
Sent from the little guy
Okay, I will try and do the charging overnight. Thanks!

I don't know much about kernel and ROM stuff, but I was just wondering...
As far as I understand, the fuel_alerted thing turns on if the battery charge goes below a certain threshold. The old bug with it was that, when recharging, the fuel_alerted thing would sometimes still stay on, even if battery charge is no longer critical.
Could it somehow be possible that this threshold is not set to 15% for me, but something around 80% due to some horrible bug?
This would explain why it suddenly turned on at around 80% when everything was fine before.
We're trying to adjust your fuel gauge and sort of calibrating your battery.
Sent from the little guy
Okay, I did exactly what you recommended.
Everything went well for about 2.5 hours.
Then the fuel_alerted process began again, but this time only for a short while apparently.
It took about 5 minutes kernel wakelock time in a 30 minutes measurement.
Way less than usual and when I check now, it's no longer active.
So. The problem might still be there, or it might not.
Do you recommend going through a few more recharge cycles to get the gauge set properly or do you think this won't make it better?
By the way, thanks for your quick responses!

Not really.
Now, when it gets to 15% or so plug it in (while phone ON), get battery calibration from play store.
Run the app, when it gets to 100 % hit calibrate. Plug off the device. Turn off.
Take out the battery for 90 sec again, reinsert it and power it on.
That calibration app is another placebo but as I said before, placebos sometimes work.
Sent from the little guy
Since the battery calibration app requires Root access, I flashed a Dorimanx kernel a few hours ago. Then I did a factory reset and the battery-removal thing. 5 hours have passed now without the bug, 3h of which were without wireless access (maybe it correlates with that).
I'll now let the battery (slowly) drain below 15% and then recharge it with phone on overnight. I will use the battery calibration tomorrow and will inform you about the results later.
Thanks man!
Good to know
Sent from the little guy
I did the battery calibration. Bug is still there, no changes
Post you battery details and a couple of BBS screens.
Sent from the little guy
Okay, here are some screenshots.
From the graph you can clearly see when the bug started.
Is it normal to have >26 kworker processes running?
Something else that concerns me: >2h without or with unknown signal. The whole day I was in an inner city area where the signal should be good...
Can you conclude anything from the screenshots?
I will now try something which I also should have tried earlier
I have a spare battery (not original samsung, less capacity) which I just put into the phone.
I'll let it fully charge with phone off and then I will try if the problem persists even with the other battery.
If it doesn't, the problem might come from the battery itself...
Is this a good idea?
No it's not.
You gotta post detailed info there, we can only guess what's draining your battery.
Sent from the little guy
Okay... I posted the screenshots you asked for...
What more should I post?

Screen flicker and device shutdown

Hi xda! So I've been having a problem for a couple of months with my SGSII and i have searched a lot but i haven't found a solution yet.
The problem is that battery behaves normally and has a normal drain rate, but when it reaches 40% more or less it drains massively and drops to 10 % (more or less, could be 11% or 9%. It is not something precise and accurate) and screen immediately starts to flicker, backlight as well, then the signal is lost and phone shuts down. After that i can not turn it on unless i charge it.
I have looked a lot and pretty much all of the forums recommended to buy a new battery. I bought another battery (original) and the problem still continued. I've also tried swapping batteries with a friend, but the problem still happened to me and not to him. Also I have tried a lot of Roms, I've tried going back to stock as well, but still nothing.
Currently I'm running Cyanogenmod 10.1 RC2 because it gives me the best battery life in those 60%.
I leave you an attachment of a screenshot. As you can see battery percent dropped a lot at the end, and i wasn't using it heavily.
Thank you in advance.
It is a hardware issue, I had the same problem (battery would drain below 10% though), sent it to Samsung, Motherboard and Charge Socket got replaced, I don't know which one was causing it because I had other issues like broken home button too.

May be there would be some hardware related problem. But why dont you give a try to to a wakelock detector app like betterbattery stats or wakelock detector? Atleast you will know which app is eating your battery or is it a hardware related problem.

Thank you for answering. Unfortunately I have already rooted my device hence voiding my warranty. Maybe i could have it fixed by some technician.

I have tried a lot of battery related apps. BBS is one if them. I haven't seen anything unsual. In fact I've also tried apps like greenify. However battery life in the first 60% of battery is actually good. After 40% comes the problem.

[SGS2][GUIDE] GT-I9100 Phone shut-off at 30%-50% battery issue

Device: Samsung Galaxy S2 (GT-I9100) T-mobile carrier- unlocked, Rooted ,Running stock rom with a Philz touch recovery
Problem occurred after about a week of purchasing a new battery since the old one got swelled... but i have two brand new batteries now both are not original but good quality (1 Year Warranty) With both batteries I had the Problem
Let me explain the problem :
______________________
Device would go off in at a certain battery level from 30%-50% (as for my experience):fingers-crossed:
To turn the device ON plugging in is compulsory... but then the battery would be Completely drained..
Also if you try to do a restart at a battery level which is closer to the sudden death the after re boot the battery will be at a extremely low level and wont rise...
I searched all of i can to find a cure to this because the last thing u expect in a situation is your phone dying?
Apparently the problem seems to be that the phone is reading the battery wrong? about a 40% so simple do a calibration Nope Nothing not even a change...
Here is what I tried
_________________
Calibration Methods - Apps and manualy
Reset the device
Let the battery chip reset
and all other methods
but finally i decided to reflash another stock rom :silly:
and I Downloaded This file I9100XWLSD_I9100XENLS1_XEN Since it was a Genuine Netherlands version but i decided not to go with T mobile this time:fingers-crossed:
I Wiped all the phone in Recovery then went to download mode and using Odin V1.85 I flashed the stock rom:fingers-crossed:
Turned it on using a Fully charged battery that i charged separately and i used it for some time max brightness max vol radio and gps wifi bluetooth etc. to drain the battery and at 38% phone started to flicker and turned off again:crying: (no Sim or Memory inserted no apps downloaded)
But i decided to go again i plugged it in ( never changed the batt) and let it charge for about 95% and turned all on again and this time i put on my simcard and memory and did all what i did except that i downloaded whats app and instagram. and also when it reached below 55% i Played some music and locked the phone (NO SCREEN LOCK USED) and after some time i checked batt was at 38% :fingers-crossed: immediately i locked it back and left it again....
Viola !!!!!!!:laugh: last time i checked it was 15% low batt warning came ( haven't seen it in weeks) and then the battery drop was a bit fast and at 12% the screen got a little flicker so i plugged it in.. I think the problem is halfway solved, ill let the battery go some cycles and update soon.. also i will attach some screen shots off the battery level too and take a close look at the time and battery level after 15% on the pics
:victory:

So yesterday I plugged the device until it reached about 85% and unplugged it when I was going to sleep, and at about 8 o'clock this morning i noticed that the battery level has risen to 96% , I think that is because the phone slowly gets to know the battery level correctly.. and right now it 11.08 am and I had turned on Mobile Hotspot and Data from 8 am , battery level is 82%.
I'll update again tonight when the battery drains completely

Can you also share the SoT ? I know it depends on how a person uses the phone but still I want to have an idea. I might also try this to have a better battery life. I also once tried that exact stock rom but without even charging completely, I went on to another ROM. So I am gonna give it another try today . :good:

Hello Eren ! Whats SoT? and you also have the same problem?

Phone went off at 43% and also figured that there has been a near vertical drop of battery from 40 % to 12% and thats when the device was standby,
phone goes off only when im using it?
Can a Expert please look into this matter and help me please. looks like all what I did has been useless

SoT=Screen on time. And no I don't have this problem. But I want to try the stock rom so I wanted to see what your screen on time is.

btw its charging now so ill give you a number when the battery drains completely
I have the same problem. when I reboot my device in most of cases the battry level showed is a 10/30% lower than before and also my phone shuts off showing 10% percent or less and the sreen brightness goes a bit crazy for 2 secs before it shuts off. I have the original Samsung battery but I also bought the 2000mAh extended kit but now this issue happens in both of them I've read that I have to callibrate battery so I will try this and post results
1. Turn off your phone.
2. Fully Charge.
3. When getting 100% signal, unplug quickly.
4. Pull off the battery and put it anywhere.
5. Wait for 180 seconds exactly (be careful )
6. Meanwhile, take this opportunity to dust off the internal compartment.
7. Put back the battery on the right side.
8. Turn on the phone.
9. Pray the Battery god
10. ... and voilà !

I did it and my results were this. My phone shuts off at 5%, slightly less than other times. I rebooted it once while 80% percent and remained the same. Battery lasted 2h and 40 mins with medium/high usage
I would say it fixed something for me but not a lot. Now im going to try it with the 2000mAh samsung battery
Edit1: now after another full cycle the battery lasted for more or less 3 hours with medium usage and shutted off at 8% now im going to try on my 2000mAh battery that had an 8% and it shutted of normally with the shutting off screen and without weird screen brightness tweaks

Well I think it worked for you because you had a Original Samsung Battery Right?
In SL a Original batt would only come with the phone :crying: Fakes have invaded,,
So i read some where that fakes dont have the original capacity? so if it is then it would match perfectly !
so now im in hunt of a original hopefully this is not a phone problem
No its not definetly a phone problem and it isn't a big deal to find an original samsung battery for sgs2 however the Samsung 2000 mAh battery kit its waay harder to find and the ones that I found are more expensive than when it came out
Yeah, I definitely think the problem is with your battery, so you just need to replace it.
Btw guys, what is your general Screen on Time with your standard 1650mah battery (not extended)? I'm running CM13 and I barely get 2h on a single charge, but then I read reviews from the early days of S2 and for instance here they have 4h24 browsing time (with screen at 50% brightness) or 8h video playback.
Is it all related to being a different ROM, or my battery just needs a retirement? Being a different ROM would impact so much on the Screen on Time? Also, I have auto-brightness always enabled, would that have such a significant impact?
Greetings
EDIT: Since I generally use the phone indoors I don't think that would be the difference in such a different Screen on Time

With 1650 mAh and on CM13 nightlies, my best so far is 2h and 28 mins with brightness at between %0 and %25 and only wifi is on.
That 4 hour SoT is probably on gingerbread though.

Being gingerbread would make so much of a difference? It's like twice as much SoT...

Never used SGS2 on gingerbread but it is possible I think. I remember reading on forums that people started to get worse battery life with ICS and with JB it got even worse. So yeah probably possible.

Hi Bolshoi! I will definetly update the SOT on the stock rom after the new battery arrives! I asked one of my friends who is in Netherlands to buy and send me a batt. Regards!

Im From Sri Lanka Achimakulo its so rare to find a Genuine Samsung battery for a older device like mine and even if i found one its either old or way too much priced
I think its because my device is so rare in this country
Is it fixed now??

battery level drop is natural? ?

[HARDWARE PROBLEM REPORT] Strange battery issues on my Samsung Galaxy Core Prime

[Notes:
• I put this thread in this section because of the "Other" tag. If it is unrelated consider moving my post, thank you.
• This is an issue report for my device, I am not saying that everybody got the same. ]
Hello,
I got a battery issue on my Samsung Galaxy Core Prime for at least more than a year.
The problem is: almost everytime, my phone crash when arround 40% battery level. It's not an informatic crash but... I'm not sure. The phone just suddenly shut down, not as it ran out of battery, displaying the shutdown logo and going to sleep, it behave like I pulled off the battery.
This is not a battery misplacement problem because the shutdown doesn't happen a totally random way: it never triggered over 50% for now.
Moreover, the battery level goes wrong after such crash. Even after waiting some time with battery out of phone I got randomly a new battery percentage that will be either lower, same or even higher than when it crashed. So maybe the whole problem is due to a shift between real battery percentage and what phone determined.
I also noticed that when rebooting after the crash the phone speakers make a weird sound, a kind of "shhhhhhhh" even with silent mode enabled and no system sound, and when it happens phone recrash on booting (system) logo.
I personally don't think it's system's fault, because between the first time it happened and now I may have flashed at least 6 times my ROM and made various wipes. Also somebody getting the same phone model than me never got such problem, even tough he is not rooted and has recent firmware. In the end the problem getting worse and worse again (=more frequent) so I'm almost sure it's a material problem.
But which one? Is this directly battery's fault or is it captor's fault? Actually I threatened the battery very badly, it's true. But everything I did — overcharging, emptying battery at the time I thought that was a good thing because of a suppoesed memory effect like nickel batteries, using charger block from an older device with a bit different configuration — should have shortened the battery's life, however it's just like the battery is now discharging a bit faster but got a kind of danger zone where you're not sure that it will keep behaving normally, so much that some measurements and developing apps determined that my battery have a good health, that is maybe absolutely FALSE.
Talking about this danger zone, I also noticed something even stranger over all.
Depending of what I do, I got higher or lower chance to have my phone crashing under 40% level:
- If Wifi is enabled, the phone got arround a half more chance to shut down unexpectedly.
- This is worse when using data consuming app (i.e. Youtube)
- Using more hardware also increase this phenomenon (when using camera) and enabling flash instantaneously and almost everytime crash the phone.
Here are what I reported.
What do you think?
It has happened to me many times. So i normally keep it charging all the time to be safe.

All the time for real? Be careful, that's not a good practice. Unless you removed the battery first, this will get worse if you do that.
I have a similar but possibly unrelated problem.
If i charge upto 100%, the battery goes directly to 0 after around 50%.
If i charge upto 50%, then the battery drains rapidly after around 20%.
I don't think its a battery problem because its the same with two replacement batteries and a stock battery. (Or maybe I have a bad luck and bought ****ty batteries)
Will post a screenshot soon...
I have the Same problem i changed the battery twice but i still have the issue

What you posted is close to what I noticed, so it is not unrelated.
This is weird that after buying two more batteries the issue still occure...
I've this problem too :/ (G361H)
I have this problem too. This is the batteries fault only.

My device goes at 60%, 40%, etc. and then it starts repedeatly pressing the right side of my screen and not letting me tap the screen, so I lock it and unlock it very fast and I can use the touchscreen for a few moments, before it shuts down without the shutdown screen and makes a *tick* sound, almost like there was an electrical shock inside the battery. I have a PRF and TWRP 2.8.7.0.

Got exactly the same problem. You can try to change the battery but in my opinion the only good solution would be to buy another phone. This is personally what I did, as this model gets old really early.

I have this same exact problem and the only fixes according to me is to buy a new phone or replace the battery. Also I noticed that the battery of my device has bulged.
RIP, I have the SM-G360T1, stock based custom ROM with TWRP 3.0.1 and this thing's started to give up. Same issues as the people above encountered. The phantom touches are getting wayyy more repetitive, the battery all of a sudden goes down to an extremely low percentage, even at medium to high percentages (such as 50-60%) and even shuts off without any notification. I also had cases where the phone would completely turn off with no shutdown animation AT ALL, plus a spontaneous but audible *TICK* that follows it. Device performance in general also started to horribly depreciate.
Well, to be fair, I had this device for 3 years and I guess it had its day. Time to upgrade.
My device has started to shut off at 80% battery levels and even worse the device gives just about 25-30 min of SOT. Also stressing the device in any way.. games, YouTube et al just causes it to shut down. I now permanently have a battery pack connected to it at all times. But even after all this, the gives good standby time. Notably the device stand for 3+hrs on 3% battery.
Still my phone is in a pathetic condition. ?
Edit - I just got a new battery (aftermarket brand though) and the ghost touches along with sudden shutdown has gone. Also the OG battery was never touching the connectors properly or the battery placement design was not proper, cause the new aftermarket battery was not connected to the connectors properly.
Peace ?
i also got this problem on my sm-g360HU , try chaging different roms and buying a new battery pack, but still this sudden drain battery still exist, it seems like it's the hardware problem already.
