[Q] Defy randomly dying

My defy is barely 2 months old, i am running CM7.1 since it was released and its quite smooth with no problems till now.
But recently i went to a remote place (i made another post somewhere) and switched SIM cards, i switched back SIM again now. Since then, my defy randomly dies sometimes while holding it and most times while in my pocket. My battery percent looks fine (i wiped it just in case).
This happened to me several times, i suspected the battery was loose, so at the beginning i reinserted my battery 2-3 times and it would start again. But now even after reinserting the battery it refuses to turn on, i usually need to connect it to a charger (or USB) and after the LED light turns on, i can switch it back on, disconnect it and use it again.. until it dies again randomly.
I tried inserting a piece of paper as padding to prevent the battery from moving, but didnt help much. When i shake it a bit, it dies too, so it might be a loose battery or some hardware problem, but the reason im baffled is why i cant turn it on again without connecting it to a charger, and also why it dies randomly when i leave it alone and didnt even touch it. Also, i never dropped it even once or mishandle it at all to make the battery be loose, when i insert tha battery, it still snaps/click into place just like when it was new.
ANy help suggestions will be appreciated. Sorry for the long post, just wanted to provide a detailed account.
I found an almost similar problem but no answer here http://forum.xda-developers.com/showthread.php?t=1109429

Firstly, check if your setVsel settings is all ok and not too low down specially the voltages settings. If you're not using SetVsel, then check your 2nd-ini in system - overclock settings, see if it enable and check those individual settings which might be too low that caused the phone under power/voltage and triggered self shut down.
Another option to narrow down your issue is trying another battery. Buy or borrow from a friend. If the case of random shut down still occur, then it might be hardware issue in your Defy mainboard. BUT.. I would flash it to another rom to make 100% sure before sending it back to the shop.

Thanks a lot for the reply, im not sure if its an overclock or vsel issue because it even dies sometime while booting up if i move it around, so im guessing battery or mainboard issue?? Ill have to check with another battery first then... hoping its not a mainboard issue coz the nearest service centre is miles away from where i live

[Q] Battery Problem

So there is this problem with my HOX.
Every time my battery goes down below 20% my phone switches off itself if i use more than 2-3 apps simultaneously.
I am not able to use phone below 20% most of times as soon as i plug in, I can use it again :/ weird!
This has been occurring for a while a now.
I have tried flashing different roms but still the problem persists.
Is there an issue with my battery? Or is it something else?
Although the Gsam Battery Monitor shows thats battery is good.
Any thoughts?
Any help is much appreciated!

Don't know if this will help and may be unrelated, but is the battery charging ok? I have been working on a friends HOX which is having battery issues, in a similar problem it keeps shutting down before the battery runs out, and was seming to charge ok, but the battery drained quite quickly after charging. In the end I replaced the battery(as the old one wasn't holding a proper charge) with a new one which seemed to fix the problem and also seemed to charge fine for about a week and then started having charging/shutdown issues. I'm yet to have another look at it but have been trying to find out more about the problem, if it is the charging circuit it can aparently be re-calibrated by holding the vol up, vol down and power button down similtaneously for 2 minutes. Don't know of this will help, but it is the only thing I can come up with that may explain the problem.

Had this today when my phone died and while it was charging on 2% it turned off.
I think it's just the cpu pulling power the batter simply doesn't have though I've never had it on anything about 5%.

[Q] 8.4 Battery Calibration ? Charging stops at 89%

Hello:
My Tab Pro 8.4 has picked up an issue - it stops charging at 89%. Battery monitor - the one built in, as well as GSAM Battery monitor - show the charging increasing charge in a linear fashion to some 85%, then the rate gradually decreases, till the curve flattens at 89%. The phone still claims that the battery is charging.
I just discharged the phone fully, let it recharge - same behavior.
I did root the phone 2 days before, I wonder, if that has something to do with it.
Thanks for any info, Paul.

Hello,
maybe you need to recalibrate your battery. This can be done by deleting batterystats.bin. Search google play, there are some apps, that can do it.

In desperation, I tried few things - first a Nandroid restore to the state just after rooting - that did not help.
Next I performed a hard reset. That fixed the problem for now.
I will carefully put back in the xposed modules I used, an see/hope that the problem does not come back.

Hi,
Did you find the actual cause of this?
I have a stock 8.4, non rooted and I find the same thing, I have attached a screen shot of the battery charge and dream. ...
Can anyone help with this please, the battery is bad enough without it topping off at 89%!!
Cheers,
Ian

Hi,
Has anyone else had this issue?
I let my tab run down to a dead battery, plugged it on over night and it is still only at 87% ...
Its driving me nuts!
I am not rooted, so don't see bow it's anything I have done, any ideas?!;
Thanks in advance

I do not have an answer, but I wanted to thank you for posting - your answer seems to indicate, that this is a issue not related to rooting.
While dealing with this, I have put back the stock rom ( but still with custom recovery on the device ) - which made charging work to 100%, then rooted again. With this config the charging worked for few days to 100%, till if failed again all of a sudden, getting stuck at 91% charge, and claiming, that the charging was ongoing for may hours.
While the charging was broken, I put on the CleanROM 1.0, and that fixed the charging problem again.
I do not see a clear pattern of this failure....

This does not "calibrate" anything. Any app that claims to fix the battery meter by wiping this file, is making a bogus claim. All the batterystats.bin files does, is indicate how much battery various apps/processes are using since the last charge. The file gets wiped ever time you connect the charger:
http://www.xda-developers.com/android/google-engineer-debunks-myth-wiping-battery-stats-does-not-improve-battery-life/
What you want, is to reset the "high" and "low" voltage flags related to Smart Battery. If there is an app that can do that, it might resolve your issue. Flashing a ROM also resets the flags (why you always need to do a battery charge/discharge cycle to get accurate readings every time you flash a ROM). So you might flash the ROM you are already on (stock?) and see if that helps.
But the issue itself is odd. If a higher voltage is achieved, I believe the "high" flag should automatically be reset. I shouldn't just "stop" at 89%.

Yes, I have (had) the same problem. I would use the tab through the day, then plug it in. In the morning, it would almost always be around 89...sometimes a bit more, others a bit less. I loaded battery doctor from the play store and set up a widget to kill all but a few specified apps (yeah, I typically try to avoid task killers, but this was driving me crazy). In my case, when I killed the apps, the battery would finish charging.
Theory (take it with a grain of salt as your mileage may vary): either the charger I am using or the tab has 'intelligence' that slows the charging down when it nears full, possibly to protect the battery. Certain apps running (sleeping?) in the background seem to keep the tab perpetually in a near-full charge state -- just enough of a drain to balance the 'slowing' charge. Every time I have killed the apps, the tab has quickly finished charging.
Again, this is just my experience. YMMV Good luck.

Try running the battery down to below 20% then recharge it. That should recalibrate the battery monitor.

I've been having issues with my 8.4 stopping charging only midway to 100%. If I unplug the cable and replug it, it continues charging.

i have had the exact same issue , mine stops charging at 54% , need to unplug replug and then it starts charging back again, also from 78% it jumped straight to 100, something is really wrong , how could samsung break something so simple and basic

I've got a very similar problem. It stops charging, usually at something like 40 or 50. If I restart it will continue charging, but not all the way, maybe up to 70 or 80. I think I tried just disconnecting the charger and reconnecting it and it didn't work but I'll try it again as that would be easier than restarting...
I sent it for service and after weeks of back and forth they gave me the old "it's rooted, so it's out of warranty".
F U Samsung. This piece of **** tablet has been messed up since day 1. First with the over sensitive screen and now this. Sony FTW.

You need to unplug the battery under the rear cover. Then plug it back in and boot up and charge it. Only way to fix. I never had issues again after doing that.

My battery has the same issue. I'm going to start charging my Tab Pro 8.4 with a lower amp/volt charger. I think the 5.3 volts & 2 amps puts stress on the internal charging / battery regulator circuit. The 5.3 volt makes the usb cable in the tablet reasonably hot to the touch. (a hunch)
Galaxy Tab Pro 8.4 Battery Replacement Video
Update: I scraped the 5.3 volt charger for a standard 5 volt charger @ 2 amps. It won't charge while in use but it does charge to 100% from 5%, powered off overnight. I also tested a 5 volt 1 amp charger (while slower) did charge from ~50% to 100%.
I would like to see others test this theory out.
Would also like to note, I believe Samsung included a 5.3V charger instead of a standard 5V so the tablet is able to charge while in use. My guess is the circuitry was originally designed for the standard 5 volts but once they saw the tablet's charge rate while on, they decided to throw in a different charger to make up for their mistake instead of a more reliable circuit design to handle the volt boost. More then likely they did tests to see if the tablet was able to handle the new charger but did not conduct the experiment for enough time to see the degrading results (faulty battery level readout).
If they knew of the issue in production they could have fixed the issue in a batch revision or recall or they flat out ignored the results and are in denial. Shame on Samsung if this is the case. Funny how they released the "better"("revision") Tab S while refusing to fix the Tab Pro. Now it seems to be biting them in the ass.
I still want to completely test this theory out and give it more time, but so far my assumption is seemingly correct.

I had another interesting experience with this tablet.... it charged 100% without notice that the battery is full(I saw this tiny little detail -battery full icon- ensures that it is really charged) restarted it to verify something and shock !!! the value dropped to 62% and the charging sequence stopped ...and even if it shows "charging" while I'm typing these lines, it dropped to 59% ). **** !!!

[Q]SM-T211 battery drain problems

Hello,
I have a problem with this tablet , when i charge it to 100% and use it for like 5-10mins i'm suddenly at 1% battery. But i can still use youtube or other apps for 40mins + So i'm pretty sure the battery is at 95% or something.
Also when i charge and stop charging it can reset the whole thing and say that i have 2% battery.
I already tried to charge 100% > let it decharge 40-50% > power off 5houres > but didn't help..
Somebody said remove the battery for 5mins and problem is gone..
Anyone done this so far?
i'm on STOCK ROM , no root or what so ever.. NO battery save app or something like that.

Hi, I'm having the same issue but it's not as dire as yours. Since you're not rooted or anything, I strongly believe it's a hardware issue, try replacing your device cause it shouldn't drain that fast. I'm using nolekat rom and it takes me 10 hours to charge fully or more but half the time for it to be drained. I haven't tried removing my battery manually but you could try that too. Most likely it's a hardware issue since you didn't mess with it so much. Hope this helps.

Hi,
My tab is getting switched off frequently though the battery is fully charged, it suddenly dies down during any kind of work and im not having battery draining problem in my tab. But when I plug in a charger or battery bank then the tab works fine with out shut downing. Is this problem related to battery or hardwire or software. Kindly suggest if some one facing similar situation

Hi XDA
I have another problem, not too bad as yours, but very nagging and upsetting. What happens is that my tabet takes practically half a day for charging up the battery. It takes like 12 or more hours to charge up from 0 to 100%. I have tried unplugging the battery as you explained many times, also draining it, but nthing changes. And even worse it is when I'm just plugging my device after totally drained the battery, so when I try to boot my device it may boot up, when it does, after one minute it's turning off because of a suposedly 0% battery. Really I might get either that 0% or 1% battery, but after a minute when I just plug it in and boot up, it may turn off even though I turned off the sceen inmediately.
I think. the problen is maybe on the battery or in the USB port, I have tested many USB cables, many chargers, charging from my PC, but the problem keeps going an and on and on. I would like to know why this problems is happening, if I could fix it up by myself, for instance by replacing the battery or the USB port. This device was a gift, and since I got it I was dithering whether it was normal or not, but by asking soome mates and reading your post I realize that this is not normal.
Hope you read this quick reply. Many thanks for your advice and giving me advice on what and how I should do...

So many thanks for your advice!! I went to buy Samsung original charger. I'm very happy now. My tablet now charges way faster (in 4 or 5 hours). I didn't ever think of this before.

Can anyone tell me the best rom for SM-T211 and the links to download it please
And thanks in advance

My SM-T211 tab 3 restart it's self after 4 day of rest or flash what can i do

Battery replaced, now won't stay on due to temperature.

Hi all,
I have been running my Z1 Compact on 4.4.4 for the longest time, mainly due to sound issues after updating to Lollipop.
Recently, the battery has been dropping randomly from 60 odd percent to 3 or 4 and then shutting down all within a few seconds. The last time it did this, I tried charging it when I got home but the charging light would not stay on, thus it was not charging. All typical signs of battery failure due to age.
Having already replaced the battery successfully on my Z1, I bought a replacement original Sony battery and replaced it. The problem persisted. On first boot, the phone got to the blue waves then black screen, and power off. Charging screen just showed the battery at about 40%.
I risked it and flashed the latest software with Flashtool, having done a complete wipe. The result of this proved no better, but I did get a different message on the charging screen, a message saying the phone had shut down due to overheating. Picture is attached.
The phone is in no way overheating and I've even booted it while sat on a shelf in the fridge to help dissipate any heat generated but with no luck.
So, the old battery maybe did overheat and caused the phone to shut down, I'll accept that as a probability. It may have even damaged something, but I don't think that's likely.
After changing the battery, I would have expected the problem to resolve itself, but it seems like some kind of hardware 'flag' has been raised that is now not allowing the phone to boot in case it overheats again.
Does anyone know of any way to resolve this, reset the 'flag' per se, other than going to Sony? The phone is definitely out of warranty due to its age, never mind me taking the back off lol
It is a shame because it has been a great phone over the years, and I would like to fix it if possible, even if to give it to one of the grandkids. I have my Z3 still (which I won't part with for anything) and I have an XZ too and both are great phones. I would just like to save the XZ1c if I can.
The phone is not, and has never been modified in any way, no rooting, no bootloader unlocking. Only stock roms have ever been flashed, and then only once or twice, to put it back on 4.4.4.
I have tried reflashing just the kernel, or just the system too, to no avail.
In desperation I even left it in the fridge for a few hours in case the temperature sensor was on the fritz, but that did nothing at all.
I just feel like there's nothing actually wrong with the phone, apart from this trigger that won't reset.
Any help greatly appreciated of course.
Thanks,
Mick

Maybe theres lot of consideration:
1. Rom Bugs
2. The Kernel not supported well
3. Battery Issues (But you already change it right)

There are two temperature sensors afaikin our phone. One in the SOC and another one in the battery (hence three pins).
The battery is probably the one giving the high temp report. Try yet another battery.
A bad battery normally heats up very fast inside and the battery temp sensor stops the battery from charging and/or working to protect the phone and the battery.
I changed my battery before when it had symptoms like yours 100-90-0 drop and after replacing with a battery from eBay it was OK. I gave it a full charge then complete discharge and then complete charge to full cycle the battery once and let the phone Guage its full capacity. one year later now my battery is acting funny again (not charging past 30%) and getting so hot when charging it triggers overheat control service in Android.

Any luck?

No, I never did figure it out. I've been loathe to spend more money on another battery when I've got other much newer phones. I really have no idea why it would not reset once the battery was replaced, maybe it's the replacement battery.
Have you tried changing the battery?
I've tried flashing different stock roms, Kit Kat, Lollipop, and it doesn't help.
Short of going to Sony, I'm not sure what else to do.
