[Q] Xperia TX Battery Problem - Sony Xperia T, TL, TX, V

Dear all, I would like to ask, why my phone battery always drop to 0% suddenly when it was about 40% or 30% few seconds before?
I'm currently using CM11 ROM and I have tried to calibrate the battery but it is not working.
Is that possible that the problem is comes from my physical battery but not my ROM?
Please help!! Thanks!! :crying:

If it stays at 0% for a long time, then it could just be a calibration problem (although I haven't had any problems with any CM11 ROMs), but if not, it's most likely worn out; buy a new battery!

May I ask what do you mean "stays at 0% for a long time"?
By the way I guess a battery that used for 2 years should be quite old already right? Hmm have to consider letting it retired hahaha.

Some phones display the battery having "0%" left, but still have energy left and the phone stays on; that usually just shows a calibration error.

Nope. The sudden drop to 0%, means 0%, the phone cannot be turned on anymore. :crying:
So I think it is really my physical battery problem then.. Thanks a lot for your answer! :laugh:

I've encountered the same issue with my Xperia V. Phone always turned off at around 20%..
Replacing the two-years old battery with a new one fixed this issue and got me an additional hour of screen-on-time in addition.

Samsung Galaxy S plus random shutdown

hi guys, i'm getting really pissed off right now
i''ve got my phone for 3 months now and it worked like charm till the last month
every time my phone shutdown randomly , and when i restart it, my battery level is under the 10%
even if i charge it the whole night till 100%, after i use it a few minutes it shutsdown and the battery will be very low.
sometimes it doesn't even turn on anymore.
i can't use my phone now only when its charging because it doesn't shutdown then.
I've tried everything that i could think of, i've recalibrated the battery , installed different roms but i got the problem with every rom.
i've even tried it with a ics rom but still got the same problem
someone please help me
my phone had the same problem i have flash any costum rom but nothing and then i have flashed a stock original rom for fix that....and then retry a costum rom.

I have the exact same problem, am about to buy a new battery tomorrow unless someone else has another solution? This might not be the proper forum but in here at least many i9001 users will read it.
I've had this problem for about a week, was very annoying while on holiday. I've tried using BroodROM BE 1.0, Stock KQE and now back to stock KPG.
Try ebay - you can easily find decent batteries for 5$ there.

Well yes I'm going to try a different battery soon but the odd thing is after my battery charge seems to drop down to 5% or so, it starts charging to about its original charge level without a charger connected. So it's basically 80%->drop to 5%->charge back to 60% without charger.
i'll try now to do a hard reset, go back to stock rom, then reinstall an costum rom,
will tell you if it works!
Plz mods remove/delete this sheeyat.. this is

i have used TeamWin Recovery for wipe all partition becouse with hard reset don't wipe /system and internal sd.

I thought I was the only one with this problem. I charge my battery to full and it starts draining normally. Then, when around 30-80% battery remaining, it turns off. It only turns off when you use it for a while, when the screen is off it stays on normally. After rebooting it turns off within a minute or so. This continues for a few reboots with the battery level remaining roughly the same. Eventually after a few boots it shows 3-4% of battery, after which I of course have to charge. Also tried calibrating and tried different roms but it still remains. I ALSO SWAPPED MY BATTERY WITH A FRIEND BUT IT DIDN'T HELP! It worked like a charm for him but I still got turn offs with his battery.
If i were you Guys, i would install stock rom and hand in my phone under warranty ( of course if you still have it ). Because if this occurs even when u swap battery, let samsung play with you phone then
Its not your battery..restore your phone to the way it was and give it to samsung
i'm getting pissed of now, even with the stock rom it randomly shutsdown.
i don't have any warrenty so i can't give it back to samsung
In case anyone's still wondering, in my case it did turn out to be a fried battery. If anyone else is experiencing the same issues I was, just check your battery to see whether or not it is swollen. If it's bigger than it should be, that probably means it's fried and you should replace it. I'm happily running custom roms without any trouble again now, and battery life is awesome!

Sorry Rajito, but you are having a serious problem, i think the motherboard is the problem, my friend had the same problem with his I9000 S simple. You shoud go to a service !
Hi guys,
I also have this problem, my phone randomly turns off and when I turn it on, it shows much less remaining battery percentage than before. (please see attached image) After turning on the value is increasing, sometimes from ~5% to 30-40% or more...
Now I have CM10 Jelly Bean flashed, but CM9 did the same sometimes but much more rarely than on JB. Today the phone 'died' three times until noon.

Yeah that's the exact same problem I had. In my case it turned out to be a fried battery, see if it's swollen or not, if you lay your battery on a table it should stay still and not wobble around. If the battery's not flat but swollen that means your battery is fried. In this case good news because you can easily replace it

unfortunately it is absolutely not swollen, its fully flat :\
besides this I put out the battery now and put it back and it is showing only 2% percent of battery so maybe my battery is wrong
UPDATE: after uninstalling the pro version of Battery Indicator there were no random shutdowns at all, but the free version is fine o.0

Battery virtually dropping, hardware or software problem?

Hello,
for months it has been happening that when the battery usually reaches 25% (but not always sometimes even 40ish) the battery indicator drops to 19% and it could either remain stuck at that value until the charge actually drops below 19% and continue the usual drop or it will rapidly drop to lower values in big steps like (19->10->4) in minutes to finally actually automatically power off. The strange thing is that it's all fake! When I power the phone again the % will go back to where it should be before this virtual drop happened and continue its usual drop, it always worked until today when for the first time it continued the "game" non-stop until the battery ended the actual charge (for hours)! You have to consider that i was in a place in the mountains where the gsm coverage was very low/non existent so it could be connected. But it got me worried because it couldn't control it!
Apart from a solution I'm asking also what the reason could be. It could seem like a battery problem but why would the phone actually recognize the actual charge after it powers off and I restart it ? Seems like a software problem (battery driver maybe?). But I wouldn't exclude that it could be the battery maybe when the charge gets low the voltage drops dramatically under stress to a point where the phone thinks its almost empty.
I'm using cm7.2 kang 119 with standard kernel.
Have you tried wiping the battery stats..?

So you say it's done that for a while... obviously it's not possible to pinpoint an app. I guess then you have some funky cruft buildup (say, a lot of rom flashes and some settings getting squiffy) or your battery's dying. I know for sure that the rather excellent Battery Widget Reborn can give a health check on the battery as part of the widget (although I dunno if it's GB compatible). The second solution may be to try a clean wipe. It's drastic, yes, but can clean up any lingering problems if you've been updating for a long time without the occasional wipe. If you haven't...then I dunno.

Baaaaaad advice. That's just a placebo and doesn't do anything. So please don't recommend it.

The thing is it doesn't happen at every single charge! That's confusing! Maybe I'll try to update to #135 and install symbiosis kernel and see.

I'm not trying to be rude. It's just that battery stats are reset after every reboot, so wiping them does nothing. It's also easier to be blunt to get a message across.

[Q] Battery on Custom Rom causes screen to fuzz

So, I have the SweetRom V5 and my battery goes down really fast. Like 1% every minute. But thats not my main problem. When i get to about75 - 50% of my battery level. My screen fuzzes with some wierd lines all over the screen. They are white and look like electricity bolts or something like that.
They go all over the screen and my phone turns off instantly. I reboot and it sais i have less than 10% battery left when i had 70% a minute ago.
I usuallylock the screen when they appear and wait a couple of seconds and they are gone. But then they come back again. Ive tried calibrating my battery with apps and myself but it doesnt work
Anyone have suggestions?
First check for apps that are draining the battery. It could be because the phone is not doing sleep so the battery is draining even when screen off
Also try a different battery.

I am sure its not a rom issue..i used the same rom & I didnt face any issues..as per my experience (& many other's) Sweet rom's are very much stable & have very very less (or zero) issues..as nokiamodel said try checking the apps draining the battery using battery stats & check deepsleep using cpuspy..if it wont help fixing the issue, try reflashing the same rom..

Make sure you wipe data/cache/& dalvik cache before you flash it. I have never seen or heard of this issue so as posted above it is not a ROM issue. A clean flash should fix your problem.

[Solution] Flickering screen, poor battery backup, sudden discharge [n7000, Note]

A month or so back I started facing weird problems with my year old Galaxy Note, n7000:
1. After reboot, the battery would go down by 15-20% and then without charging the battery %age would gradually increase by 5-10%
2. lots of flickering on screen followed by auto shutdown whenever the battery %age went below 15-20% after normal usage
3. Very poor battery backup (I blamed most of this to the Rom Mods I had been installing at that time- only partially correct!)
I am sure that many of you might have been facing such problems and running from forum to forum to get a solution- I did.
Solution:
Get your battery replaced- most of us have had our Note for a year and some months now...life of the battery is approx 1 year for regular use, thus, the stock battery that we got with our Note is well past....
I never faced the above problems after battery replacement!
Hope this helps others like me!!
I started having this problem after getting a new battery, my old battery which was weak never showed flickering. But this new one which is original samsungs battery at below 15% show flickering and sudden discharge despite a good battery time.

I got rid of the damn problem after getting new ones...Is it possible that the batteries you bought are not genuine/fake?
Which ROM are you on- the Stock one or some mod-rom?
When I was searching for a solution to my battery issues some members suggested battery-calibration and full charge-full discharge cycle to get rid of the problem. Both the solutions suggested at that time did not work for me.
There was also a solution about cleaning the mini-USB connector which gets seriously dirty collecting grime from our pant pockets! That did work for me initially when the battery was good.
Please let me know if any of the above helps you.

Guys - Me too have the same issue, but this started immediate after updating the Jelly Bean 4.1.2. It never happened while on official ICS.
I could observe the battery is very much thick now, which is a symptom of over charging. The screen flickers and brings phone down abnormally.
After connecting the charger for a 5 seconds, suddenly the battery level shoots to original state from where it went down. Most frustrating, it happens very frequently.
I am not sure if the same will persist even after replacing with a new battery. Or I would need to go back to ICS again.
Any suggestions?
Cheers!
If the battery is bloated then it's better to get a new one.
Erm... is this thread still up?
I just wanted to know if the bloated battery would cause boot issues, stuck on the model screen?
I would guess the problem is with the bloated battery's voltage is insufficient to power up the systems... i guess
I need confirmations... thank you in advance

4.1.2 xxlsz deodexed by eybee
The problem is, after I restored most of my data, apps and system data separately, the screen flickers a little bit and then the restore process completed without any problem. After that I restart the phone, stuck at the model screen only for unknown reason. The data is also from previous xxlsz which I had trouble with some system app crashed but fixed by returning to another backup though.
So, currently I'm leaving the phone without any data restored, only stock fresh out of the box xxlsz with titanium backup only installed. So far the phone is quite stable, I've turned off the adaptive power adjustment in display as well as lowest brightness just in cast it might occur again.
I've been reflashing xxlsz a lot this morning, over 3-5 times due to stuck in boot logo and model screen. Even though flashed the latest philz 4.90.8, it would just revert back to the old philz 4.8x with cwm 6.0.2.8
One last thing, my batter bloated pretty bad about half of it has been expanded. I mean from the bottom part (no copper connections), half of it has reached out of the body.
Well,
hppend to me b4, flickering issue below 10%. It was bloated. Bought new one. Bloated again after 6months. Again, bought a new one and it can last only 7 hrs without switch on data.
This is what we get from massive production company.

Maybe you bought a "bad" battery...
Ok, successfully restored to another checkpoint, now trying to extract a stock build.prop from stock xxlsz, eybee's build.prop I believe been making my phone goes hot and consumes more power than normal (I guess)

I seem to have the same issue
1. Battery drains rather bad
2. Screen flickering
3. Auto shutdowm
Used the battery in my wifes n7000 , however no issues at all
Only seem to happen on my phone.
I flashed it to stock std 4.1.2 , however problem still persist. auto shutdown few times a day
Gets worse when i use an external SD
@amogh you can check your battery voltages and battery temperature and compare that to optimum values. you can also use apps like AnTuTu battery tester.

Flashing another rom again wont solve much of the problem, if you happens to have the phone stuck in around bootloop and able to go into cwm, brace yourself, this process can get very repetitive to solve because a mere battery able to do such a problem. I had these experience before about 2 months ago before buying a new battery. Hope this link helps you understand a bit more of the battery

I had these experience before about 2 months ago before buying a new battery. Hope this link helps you understand a bit more of the battery

Thanks mate will go thru it and see if the battery is the cause. Point to note was it did not happen when i was using ICS. It started immediately with the JB update

Just flash the stock firmware and kernel, and see if it solves the problem. If not then you have a dead battery on your hands.
I also have the same problem, it also seems to happen at 30 percent. I'm pretty sure we need to change our battery

Well its the easiest way to see if it is rom/kernel related or if something is wrong with the hardware.

ok thank you. just one more question just to be safe, should i just download the firmware from sammobile and flash via odin in download mode right?
and another fellow here advised me to calibrate my battery to check if its hardware or software. he told me to charge to 100% and delete this file data/ system / and delete BatteryStats.bin use to 0% and then charge 100%. should i do it before going stock or not?
had the same issue a few days back (f2 stock rom and kernel), battery dropped from 17% to 0 within a few seconds.
but this occured only once, the next cycle was ok, so i guess it was a calibration issue!

Easiest to try battery calibration first. If that doesn't work after a couple of cycles then just flash the stock rom from Sammobile using Odin.

ok thank you guys, i guess i just have a ****ty life and very very ****ty luck happens to every phone tablet i buy. FML
There are 3 possible reasons this happens - broken phone, broken battery or software problem.
I think the first one is unlikely so you need to figure out which of the last 2 is.
Make a back up of your current rom and install an official TW software. If this still doesnt fix your problem, its most likely the battery. A new genuine battery is around 20$.
PS - i think that the battery stats bin file is automatically deleted once you fully charge the battery anyway but you can still try it altough i doubt it will fix it.

same problem here
And here.
This is typical of a dead battery. Your best bet is to buy a new one.
Less than a year is short but not unheard of. Overheating (especially when 100% full), deep discharge, very intensive use (especially with quick charging) and manufacturing defects all can kill a battery.
I'm on CM12.1 with this problem. I've tried battery calibration and tried a new battery but its still apparent.
Will be trying a factory reset as my last resort.
This is happening to 2 phones in my household it started after the upgrade to 5.0.1 one note is Tmobile the other sprint....highly doubt we both developed battery problems RIGHT after we both ota upgraded.
Same here at ~13%.
I do always either fast charge or QI charge.
So far I've tried:
- Battery calibration
- Bought new battery
- Factory reset
Still happens!!
Maybe I'll try TW flash or modem change
Weird, I have this exact same problem as the original post. I'm running BOC5 on the 9105. It's a sporadic problem only occurring on occasion

I've been running Lollipop for ages until this problem happened. Frankly, I still prefer Lollipop with this problem.
