Hi,
Just ask for any other information, I'm bound to not remember to provide everything Have had this i9100 for about 30 months. No battery issues for the first two years but plenty in the past six months.
Phone would switch off suddenly (no low battery warnings) or go black / unresponsive and super-hot. Replaced the battery and after about 2 months the new battery (probably not original) was literally bent and mis-shapen. Bought a genuine (I hope) Samsung battery and installed CyanogenMod and still seeing hard power-offs when they wouldn't be expected.
See attached for this morning. Phone unplugged after charging (via USB) all night. Attempted to use Apollo and it wouldn't work so didn't even use the phone on the bus. Clearing data for Apollo after arriving at office and that is working again now. Made one long phone call before starting work and towards the end of that phone call just dropped. When arrived into the office plugged back into USB again.
Why did it power off at 70% and why wouldn't it turn on again even though after being plugged in and charged for 5 minutes it starts up at 40%?
What do you think? Is this a hardware issue and I have to give up on the phone
Does near camera get hot ? it shows media taking 21% which I assume it is not normal .
also we need to know about Rom version and recovery version .
Media scanner is the process that scans every folder and file so that if you copied or downloaded a .mp3 file it shows on your library . However for many reasons this can go wrong . Do you have folders with many files ? (talking in thousands) ... for example apps like maverick can download many thousand mapTiles that saves on internalSD or ex ... Then MediaScanner everytime needs to go trough all those many thousand files and that burns cpu/battery ...
if so try http://geeknizer.com/fix-android-media-server-scanner-sdcard-cpu-battery-drain/
other than that battery can go bad which is easily replaceable .
Attached screenshot from this morning. Notice how it drops to zero at a point. The phone switches off even though the battery isn't exhausted.
Near camera not getting hot. Not sure whether media 21% was normal or not, that morning only 30%+ of battery used when the hard switch-off event happened.
ROM is CyanogenMod 10.1.3-i9100 (Sept 23rd) and recovery is CWM v6.0.3.6
No folders with many files. Use the phone lightly really. A few MP3s, email, phone calls, general browsing, occasionally Skype.
Real question is why the drop from almost 70% battery to zero, as shown on last weeks and this mornings screenshots?
Battery is brand new, unlikely to be the problem.
Will install a battery drain app and study closer.

The most advanced app I can think of is battery monitor widget pro which can show you energy flow in mA per ( by default every 10min ) . A stock i9100 has a 1650 mA .However I don't think it can explain dropping in energy like that . No battery saving app will resolve this issue . There are some battery calibration apps around . I don't know what they exactly do ...
I have an i9100 . There has been some " Episodes " when I shut down , remove the battery and re-enter , turn on and see unexpected drops in the juice but the most extreme was dropping from 38 to 15 . Never when running android .
When phone gets superhot for not reason it sure is using alot amount of battery . I would suggest a factory reset or changing rom/recovery .
Plus I would like to know do you experience a crash ( after going dark you simply turn on the device again ) or drain battery ( which your device wont turn on until its in charge for a few seconds/minutes ) .
If everything fails I would be suspicious about mainboard .
----------------------------
On a second Look I suspect the gap you are seeing in the battery is a state when you experience a crash which loads the cpu that uses juice enough that android is running to record the gap but not functional enough to respond which result in something like the image above . I don't believe the battery can go from 70 to 0 then when you connect to a charging point you gain 50-ish % battery in a jiffie . When I think back I can say I had battery stats like that and my phone still is without issues ...
It's not getting super-hot any more. I think that was down to an old battery. What confused matters somewhat was it still got super-hot with the replacement (non-genuine) battery, which after a month or two was actually buckled out of shape. The phone was running Samsung ROM then.
Since then, have installed CyanogenMod and genuine Samsung battery and it's better behaved in general. Just these occasional crashes or whatever they are.
When it goes black, it won't turn on again, until after the phone is plugged in for a minute or two. Then it will turn on and report much higher than zero battery. It could still be some kind of looping crash where the screen is black but Android is still running. That wouldn't explain why it recovers when plugged back in though.
Since these issues are across 3 different batteries and 2 different ROMs, I'm tending to suspect that mainboard myself. And I don't trust any of the high-street phone repair places. They have two options for me: (1) sell me knock-off batteries, (2) replace mainboard.
The phone is still functional to an extent, it's just I can't rely on it. It's good for a half-day, after that I can out and about uncontactable and unable to take a snap photo or whatever on demand. Annoying!

DISCLAIMER - I am just putting this in here so that if anyone gets any funny ideas ... Whatever you read/use in this How-TO Post is at your own RISK. The aim of this post is to help others who had the same issues as me when they were abroad ... and were stuck without a mobile Running MGLDR 1.13 and DFT stock ROM (WP7) and a USB cable but no other chargers ... If the OS doesn't boot you WON'T manage to charge via USB UNLESS you follow this HOW TO GUIDE (it's the ONLY ALTERNATIVE YOU HAVE OTHER THAN BUYING A CRADLE CHARGER) ... it WORKS 100% but I am fed up of finnicky people emailing /posting / trying to play the "experts" on the matter when they know nothing about the matter
Dear all
After going through all sorts of Registry fixes which were momentary in nature. I decided to find a viable alternative which does in actual fact work with all current WP7 builds and all MGLDR's provided with a USB Storage option.
It has been said that the WP7 Software does not charge the battery to its full potential. I also incidentally ran into the problem of charging the mobile when the battery died. Primarily because the mobile loads ... restarts ... loads ... restarts and you keep on "praying" until the OS boots to get it charged.
Alternative fixes so far which worked for me were:
- Adding android to your SD Card ..booting in android and charging it in android mode
- Charging it in Cradle Charger
- Some people even pulled out 2 wires from a USB cable (+ve and -ve) to get their phone on again (crazy and dangerious)
- MGLDR 1.12 hangs when trying to charge mobile while it is off.
- MGLDR 1.13 reboots (as a momentary fix) in order to avoid the hanging caused in 1.12
Problem is
- I can't stand the fact that we have to have 2 OS'es to get it charged properly
- I can't stand the fact the we have to remove the battery in order to get it charged externally via cradle charger
So we have to adapt to the present circumstances unfortunately. If nothing, and the fix does not give you more battery life, this method avoids you from
- buying/carrying a cradle charger with you when abroad.
- having a dual boot system (WP7 / Android) on your phone
- making you do crazy/quick fixes such as the USB cable thingy mentioned above ... (don't try it)
no need for anything of that!
HOW TO:
So in a nutshell if you drained your battery too much and don't have a cradle charger ... with the added bonus that you may get improved battery life out of WP7 is the following.
- Boot into MGLDR setup menu (hold the end call button at start up)
- Boot your mobile and hold the "End Call button" to go into the MGLDR setup screen.
- Choose USB Storage menu
- METHOD A - Let the mobile Charge for 6 hours (typically overnight would be ideal) (Note: It will not over-charge and it will not damage your battery.
OR
- METHOD B - Charge the mobile for 4 hours (to keep mobile on overnight) and charge the last hour in usb-mass storage mode. This has the added benefit that you do not get your screen on for a long time. This will not damage your battery and those of you who are worried about over-charge can go for this alternative and not take any risks.
- NOTE that you will NOT get the charging indicator ON in this mode. PRECISELY that's the whole point of charging in this mode, the battery will charge to its fullest as it is not under the influence of the WP7 software. It is like as if you put the battery in a cradle charger and charged it outside.
- When you wake up ... hit the back button to go to main menu and choose RESET option to reboot your mobile : ) and voila!
RESULTS:
- I got improved battery life charging the mobile in this MODE. I got 36 hrs + of battery life (normal usage) which is very good.
ADDED BENEFIT: QUICKFIX FOR DEAD BATTERY - NO CRADLE CHARGER - NO DUAL BOOT
- There seems to be mixed feelings about this as some of the readers have reported no discenable difference in battery performance. While I will not contradict these people, I got improved longevity from the HD2's battery. Clearly the OS is reporting the battery level badly. If NOTHING this method still serves as a quick fix
- if you drained your battery and cannot get your HD2 on again
AND
- You Do not own a cradle charger
- Registry did not work for me.
SETTINGS - WHICH IMPROVE BATTERY LIFE:
- You can optimise settings as follows in order to get my same results, again I hear many of you not wanting this as it turns of features from their PDA but as I said above, we have to adapt for the time being:
Settings are -
- ROM DFT Stock ROM original build (issued 13/01/2011)
- Radio 2.15
- Screen timeout 30 seconds
- Screen brightness set to auto
- Wifi turned off (on only when needed)
- Bluetooth turned off (on only when needed)
- Location turned off (on only when needed)
- Data Connection turned off (on only when needing to check mail)
- Email sync turned off (not every 30 mins)
- 3g turned ON - UPDATED - I got better battery life with 3G ON but this may change from country to country so I suggest that you have a go with 3G being ON or OFF and see which is better for you....)
IF YOU USE THIS POST - HIT THE THANKS BUTTON - IT's the LEAST you could do!

Hi Alcatrazx,
sounds logical I´ll give it a try and report later, thanks.

Thx
Thx Bro!
Will try it later too. I'll report.
One question though... Do you need to do this everytime you charge your phone, or just the first charge?
Sounds interesting, I will try and report

Sounds like you have to do everytime... If you reboot your WP7, the battery is under the influence of the software again and does not charge correctly. Beat me if I'm wrong
Very interesting. I will try it
It's a good idea for some times, but I would not use it as an every night thing.
I sometimes get calls or messages during the night (and usually they are important). Another thing is that if you use your phone to wake you up this will not work at all.
I hope WP7 development progresses and solves this issue in the upcoming updates.
Nevertheless it's a nice way of going by, and thanks for taking the time to test it and post about it.
PS: does the light turn green after 6hours of charging or not. Probably not, but worth asking .
Another solution should be to charge a second battery in an external charger...
pronor
Another issue with this "workaround" is that MAGLDR keeps the screen opened, which can cause some devices to overheat, so be cautious with this one. I say that an external charger is the smartest alternative. I actually use this method and it works perfectly.

Sorry to sound pessimistic, BUT, people have already reported clearly in other Threads that they have tried the solution of charging their battery using an external charger with no luck. I can't see how this is any different. In addition, 6 hours will probably kill your battery in the long run (overcharging) - I have queried HTC support about it in the past.
Simple enough mate! Though 6 hours of battery charging will probably make significant damage to your HD2 battery... HD2 normally will charge in about 1 and a half hour or 2 udner WM6.5 or Android!
Not bad idea though! Bravo..
Charging while in Android remains for me the most convenient option. I must say though that this battery issue in wp7 is not that obvious for me. The phone charges quite well in wp7 and only sometimes I feel the need for a restart, after which the percentage increases with 15, not more.
most chargers since the beginning of time have a battery cut off, when the charger unit detects the polarity is starting to reverse it switches off, of course i cant say for sure using the MAGLDR method would use this, potentially it could just be a case of "connecting two wires to a battery" which as you guys have pointed out would not been good, at worst your battery could get seriously hot, or potentially if you reverse the battery polarity enough you would have half of a battery thats unusable.
I think what should be taken from this however, is that like myself and other have been saying for a long time, if your battery is charged propperly it will last a long longer, people reporting empty batteries within 20 odd hours, in my opinion, either have dud batteries or are not charging them properly
the MAJOR plus side to this post is the ability to fix the empty battery restart issue, that alone makes this idea a gold star and should be stickied!

People reporting these batteries issues my friend are people who are knowledgable enough to reach to xda-developers forums - i.e. people who have a pretty good understanding of what battery drainage is and whether their batteries are dying or not; who have installed a number of winmo roms, android roms etc.
there are roms that drain battery and others that handle power better. in the ports of Windows Phone 7 for HTC HD2 there is an issue with battery drainage, and thats a fact.
There is no issue with bat drainage but with false bat stat reporting.

your level of wit and sarcasm is actually quite funny given that you completely got my point wrong, the issue is quite simply this, the drivers for our HD2 are copies from another device, a device that is similar but not the same, the issues we have with battery are down to the fact that WE do not know if the battery is charged or not, at least at a first glance, and given the inability of many people on here to actually read threads and posts correctly it is not beyond the realm of possibility that many users dont know what level there battery is charged to, thus it may not be charged propperly.
If windows reports a full battery and its only half full then it will "appear" to empty twice as quick, now i think thats pretty clear for every one?

we cant
our phone must be different to a degree than the phone this ROM is based off otherwise we wouldnt have the issue, lets all assume for a second we can actually start chopping and changing files in WP7 like WM. We would need to find some sort of driver that exactly matches our HD2 and i doubt that will happen.
whoever made the driver isnt going to just bring out a new version for an old peice of hardware that isnt supported by MS, perhaps if a new piece of hardware has the same battery controller as us something can be done.....maybe

You have the following options:
1. Try the registry tweak. That worked for me and I actually have no battery issues for the last 2 weeks or so.
2. Charge the battery under Android during the night. That's pretty usable as you only need to reboot and you still have a fully functional phone Way better IMO than the USB Mass Storage trick.
I have a minimal Android installation on my SD (Angry Birds, you know) and it currently reports roughly the same values as WP7.
Hi all,
I've got my sg2 since june and since the first moment I have got the same problems. I had the stock ROM & kernel with android 2.3.3. The problems I experienced were these:
1) extreme low battery life (6-10 hours, with normal usage)
2) when using heavy apps, my s2 just suddenly turns of. When rebooting it, it has a battery drop of like ~15%. (this only occurs when battery is already bellow 40% left).
3) Like 5-20 times a day (it really difference day-to-day), I got the notification that I have to put my sg2 on a charger. - So the battery bar drops from example 80% to 1%. After like 1 or 2 minutes it just fills up back again to the 80% before. Sometimes when this occurs, it also turns in a few % (like 80% before, and afterwards 75%).
So what did I already tried to fix this?:
- bought new 1600mah battery > didnt solve the problem, conclusion: no hardware malfunction
- I thought the problems could be occured by the tiny space between the battery and the frame of the phone. So it had a lack in connection... So I filled up the little space with i tiny piece of paper> nope didnt helped.
- downloaded mutiply apps for battery saving, task killers, etc etc.> didnt help!
It's really really frustrating, and I'm guessing more and more it's just a software problem. I do have warranty/insurance on it, but i don't want to send my phone to a repairservice because then I've no phone for like 3 or 4 weeks.
So my last option for me was to try a custom ROM and Kernel. So last week I installed the Lite'ning ROM. I also followed up the advice to calibrate my battery, so i did.
And the first day it was running really smoothed! At the end of the day my battery was still alive and I've used it for over 20hours, so I was really statisfied... But a small sidenote: I had a really busy day at work, so I didnt use my phone that much.
So next day, used it alot more. After 5 hours it had only 50% left.... And that's not all, my phone turned off suddenly. Not once, not twice, but 5 times that day.
Seems all these solutions didnt help. The only positive thing of installing Lite'ning ROM is that i now have about 4 or 5 hours more battery life a day.. But if I use it alot, it shut downs a lot more. Wich lead in more battery drops after reboot.
I'm really desperate, and I really don't know what to do now. Does someone have got these really frustrating problems, and do you guys have got some solutions?
And one more question: is my warranty/issurance voided after installing the Lite'ning 6.1 ROM? or can it by tresspassed by using a Jig?
Tnx for your time, and I really really hope you guys can help me cause i'm really getting sick of all this. It's killing me!!!
ps. sorry for my bad english
your warranty is voided by installing custom rom but u can unroot and use the jig to remove counts in counter.
now apart from that it seems if u use your phone for 5-6 hours continuous it will drain the battery because main source of battery drain is the screen display but for moderate use it should be a little over a day.
i am unclear about your usage but still if you have doubts you should really get it checked at a service center.
I would flash back to stock, use the jig to clear the flash counter and exchange that phone, seems it has some type of hardware issue that could be related to temperature as it only shuts down when you use it.
My 0.02 cents

My usage is definetly not THAT extreme, i guess moderate: I never watch movies or youtube, just some messages with WhatsApp, about 4 of 5 times a day checking Facebook, same for Twitter, always GPS off, some time of the day Wi-fi on, never play games, always closing apps on background.
i've got an example of my battery usage (this is one of the best battery usage days i got!!!):

Today step 2) happened to me
I got my galaxy s2 (international version) about 4 months ago. Recently I've noticed some weird battery drain mostly when I restart my phone, but it happens other times just out of the blue.
It might be a software bug not showing the proper battery level, but I've attached pictures that show normal battery drain even after that jump down. Obviously, if it was a a software fault the battery percentage should remain level or go up slightly. (Yes the battery level does go up a bit, but I lose significantly more battery than I gain.)
This has happened in many instances and I've only got a screenshot of two. Sometimes I get big discharge and at other times its small. It's pretty annoying when you think you've got enough battery and go out, only to find the phones dropped 20-30% out of nowhere.
My phone is unlocked and not branded (bought from carphone warehouse UK- CPW). It's running stock XXKI4 firmware (2.3.4) and I'm not rooted.
So my question is, has anyone else seen this happen or have I got a faulty battery? Is there a fix?
Hi there,
Battery drain is one one the main argouments you can find in this forums. ATM I'm in your same condition: after latets ROM ugrade (I've got latest CheckROM release), my phone "sucks" al lot more battery than before.
A lot of things could affect this: themes, skin, kernel, application bug, bad battery checking and so on. There isn't a valid answer... I think you must indagate on yourself, comparing what you find with forum's infos!!
Good luck!!

There are several threads about battery drain.
For example here => http://forum.xda-developers.com/showthread.php?p=16973603
Maybe you find a useful tip.
You have always test it on your phone under your conditions.
You can try to flash special (Custom) ROMs and kernels, which are optimized for better battery life, but as there are so many different influences on battery life, it is nearly impossible to find a general "fix" for all users and phones.
Good luck!
well at least yours lasts 15 hours, mine lasts at most 10 hours on heavy usage.
P.S. I am using 2.3.5
As to Anwser to those "drops" or "gaps" in the graph, just recently i noticed that my phone was working normally, i was monitoring its battery drain (i have a thread going on about it), and after some time of no using, after class, i noticed that my phone asks for my SIM PIN again, and is in Safe Mode (i dont really know what that it). When i checked the battery monitoring graph (battery info) i notice the absolutr same fall (from 70% to 40%), but i remember that i saw and used my phone at 60-50% too ! So i can only assume that the phone crashes, eighter reboots for some reason, and the data isnt saved (for example it saves the data every 2 hours or so), so there appears the "gap".
Thats simply my opinion, but i do remember using the phone at the % between the two extremes (IN the gap), so i guess the data wasnt saved.
EDIT: Ha! I'll add some pis now to show you guys this: so in my current history i have two gaps, one big, and one smaller before. So, the first time, i turned off the phone and PULLED OUT THE BATTERY aswell cause i wanted to check my batteries mAh (its 1650 but thats offtopic). Thats how the small gap appeared ! As for the big one, my phone seemed to crash and reboot while i didnt notice, because in an hour or so of no using i woke it up and it asked for the SIM PIN.
So there, i think the phone eighter crashes or doesnt manages to save the battery data, and those gaps ("falls") appear.

Hi
I searched the web and also on Xda but I could not find an answer to the problem I got. I want to know if anybody has the same problem as I have. Firstly I want to clarify that I am NOT talking about a normal battery drainage caused by background apps, foreground apps, enabled wifi, bluetooth, google background activities, synchronisation, facebook, google location settings, any antivirus app or something of that kind. There are plenty of threads about that and google search is full of this topic. I am talking about something else when it comes to sudden and quick battery drainage.
It already happened to me a couple of times when I use the built in projector of my phone (samsung galaxy beam). So I watch a movie on the projector and it takes let say.. around 30 percent of my battery life. After I turn the projector off, close all foreground and background activities I wait like a minute or 2 and the battery status drops from lets say 28 to 20. This is normal as the battery status somehow needs some time to get "updated". So after every single fore- and background activity is closed and I got 20% battery left I go to bed. Then in the morning I look at my phone and its dead meaning the battery dropped to 0 causing the phone to turn off. And thats not normal for me. (I do hear the sound of very low battery in the early morning meaning it doesnt turn off within 1 hour which would mean faulty battery) First I was thinking that this problem might be caused by previously overheating the battery but I checked the temperature and here all is fine. Also both batteries are not too old and still work normally (beside the described problem). I may add that using the projector itself is not an "extreme" usage of the battery. When I use the projector, play an HD android game connected to my ps3 controller ...that is a different story.
So my question is what could cause this rapid battery percentage drop even tho the phone has no activity at all and sleeps. Sometimes it happens and sometimes it does not tho..If I would not use the projector then I loose around 2-3 percent overnight, if I use it then I sometimes loose 20% without doing anything. And thats not normal. I understand that a lot of people dont have my phone, but I still would like to know if anybody had the same issue on his phone after "heavy" usage? Maybe android somehow thinks that there is still activity even tho there isn´t. Like a virtual activity making the battery think its in use and therefore draining it. Any thoughts on that?

This is a case where actual current measurements will narrow things down.
It could be that when you turn off the projector, there is still some hardware drain going on.
It could also be that the last "20%" of your battery is really only 1%.
For current measurement, see: http://forum.xda-developers.com/showthread.php?t=2487055
this can be due to some defect with ur battery or with the charger that you are using, you can rule this out may be by trying different charger and also changing the battery to rule out the battery defect. what @Renate NST say could also be the issue.
Problem solved
Ok. Just a little heads up. I managed to solve the problem. Thanks for the replies. This is how I solved it:
1. I first ran this app ( Battery Life Repair) to check for any faults in the battery itself https://play.google.com/store/apps/details?id=com.BoshBashStudios.batterydoctorrepair
2. Then I installed this app (BatteryCalibration): https://play.google.com/store/apps/details?id=com.nema.batterycalibration and followed the advise as written on the app (regarding full charge and discharge- I discharged it until the phone switched off). Find the XDA thread of this app here: http://forum.xda-developers.com/showthread.php?t=1024867
3. After I watched a movie on the phones projector I restarted the phone and it stopped from draining the battery until 0 and went back to a normal discharging state
So with a bit of heavier battery usage (watching a movie on the projector) the phone or battery somehow memorized this usage, and thought it has to continue in this state even after I ended the movie and turned the projector off. But the above 3 actions solved my problem. Its important to mention that you will still loose some battery life as you need to restart the phone. But this is obviously way better than having the battery run down to 0% for a virtual usage... :good:
PS: If you still got problems with ur battery you might want to replace it or change your charger...

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.
