Battery drops instantly to 0% empty - Galaxy S II Q&A, Help & Troubleshooting

Hi,
I can't use my phone without plugging it into a charger and socket and when I remove my phone from charging, it turns off itself and I can't open anymore so I decided to buy new battery(im not sure if this is original) since I thought it just a battery problem and now I can use my phone even if it is not plugged into a charger but the problem now is my phone shows more battery % but after several minutes, it turns off and it shows that the battery is at 0% so meaning it drops to 0%.

Battery shows 100%, when it has 3800mV

This is my first post, hope you can understand what happens to my phone (SE X10 mini pro - U20i).
When I connect it to my wall charger, it starts charging normally, no problem. If I charge it overnight, what it is supposed to happen is that it charges to 100%, then it stops automatically the charging process, "waits" untill the battery drops a given percentage, not sure how much, and then charges again, and repeats this process until I disconect the phone. This is the normal process, and usually does this.
But some times, what it does is charging to 100%, stops charging and it remains in the 100%!!! Never drops, and it discharges the battery much more rapidly!! I have System Pannel, and when this happens I see that the processor is allways in the 10%, which is not usual in standby... and as the battery is discharging, the % doenst change, still shows 100%, when it is maybe in the 3800 mV. When I disconnect my phone, the % starts decreasing rapidly, as if it was trying to "compensate", ah in maybe 30/60 minutes reaches 50%... This is not normal, and I think it is some process that stops associating the % of the battery with the voltage.
Ever heard of something like this...? My phone is temporarily rooted with Z4mod, with stock firmware. 2.1
try this:
install xrecovery
make sure your battery is at 100% (let it charge over night)
go into xrecovery (press back while the SE logo appears while booting)
go to "advanced options"
delete battery stats
and drain your battery till your device turns off, doesnt matter how
No go. Doesn't solve it... Going to try to charge it tonight with the background data option turned on. Have it turned off to save battery. Probably won't solve it, but it doesn't hurt to try.
This weekend I've charged it WHILE turned off, during the night. Got it off the charger, symbol in screen appeared with full charge, turned it on, it immediatly shown 18% battery left... This is really weird. Can it have anything to do with not using the original charger? I'm using the original as a travel charger, in my bag, in case I need it at work, and at home I use a Nokia charger, with an output of 890 mA, and with the adapter to microUSB (which actually gets very hot). Do you think it can have anything to do with this issue?
Turn off data traffic and "sync now", you will save battery.
With data traffic and sync on, my phone last just one day ( about 24h ).
With it off, It last about 2 ~ 3 days.
Result: I just turn it on, when is needed.
try turning off data traffic and as ur phone is rooted use SetCpu and auto killer memory optimiser....nd never over charge ur phone....charge it only when the battery is <10% and charge it until it gets completely charged....nd as soon it gets charged disconnect it.....nd set the SetCpu to ondemand and auto killer to optimum...see if that works for u..
lso get ur battery checkd if thats ok...

[Q] Xperia Ray off at 28%?

Hello people, I have a strange problem, I have less than two months with my SE Xperia Ray, and always loaded with original charger , but about two weeks ago or something but the phone whenever it reaches 28% of battery status and jumps to 0% and off. the battery is completely discharged. Sometimes I'd see battery calibrator used but still the same, any suggestions you can give me if they had a case like this? thank you very much
Do calibration! Let your battery became absolute empty and phone will turning off automatically. Then connect the charger (!just charger, do not turn on the phone!). When batery turns full disconnect the charger, eject the battery for 5 minutes, then take it back and connect the charger again. Then it became full enter recovery => advanced => Wipe Battery Stats, then restart your phone and when your home screen appers disconnect the charger. Let your battery became empty to the end (!do not restart or turn off during this period!) then charge as always

[Q] Battery is giving strange problem,what should i do?

I will try to explain my problem clearly and in a concise manner.
My battery started giving problem since a few days back.That time I had ICS in my phone.
My phone having enough battery gets shutdown in the middle of nowhere.
If i turn it on,it shows battery to be 0 or 1%.Then i used to set it on charging,and it used to work normally and battery starts getting charged from 1%.
On the other hand,if instead of turning up the phone and charging again,when i used to plug the charger in without turning on phone, my phone shows the correct battery percentage.And it starts charging normally.
To summarise-
My phone having enough battery gets shutdown in the middle of nowhere.If my phone gets off on 70% automatically,and if i plug the charger keeping the mobile off,it starts charging from 70%.But if I turn on the mobile and plug the charger,it starts charging from 0%
So this thing worked for a few days.After that my phone started turning off quite frequently.And I had to plug the charger everytime it turns off so as to turn it on again.
A couple of days back,I flashed cyanogenmod JB and siyah kernel.Since then it has been worse.
Now phone doesnt even last a minute even after full charging.It just shuts down as soon as I turn it on.I tried clearing battery stats.
I am unable to use my phone,its next to a dead phone.Please help !
What should I do to save my phone?
maybe its time to replace battery...

Are you sure battery needs to be replaced?
One more thing, after flashing JB, the battery percentage doesnt fluctuate as before.
It gets off at say 70%, and then it doesnt matter if i charge it keeping phone on or off,the charging starts at 70%.
Its just that the phone gets off for no reason as soon as it is turned on.
There is an app on market called My Battery Status, you can check your battery health with it.

Replace the battery

[Q] Phone stuck at 0% charging, even though battery is charged. Why?

Hi All,
Please help me with my battery problem.
I was playing some game, the phone had around 30% battery. Suddenly it went off. Then I tried turning it on. It showed 0% charging. I left it for sometime, it still showed 0% charging, and since then its showing the same. It shows 0% charging when I use an external charger to charge it, as soon as I unplug it, it goes off.
My findings :
I trired a few on and off tricks, I cant calibrate coz I can't charge phone to 100%. Then I left the phone on charging for a few hours, it did charge, and somehow the battery showed 100% charged, but when I unplugged the charger, the phone shutdown quickly.
The battery is in good condition, I have used a few apps to check that. The battery is still charged, but the phone doesnt know about it, and reads it differently, phone always finds battery to be 0%. The battery stats show "0 seconds on battery",so I guess the phone isn't using battery at all. I tried hard resetting as well. I believe its a software problem not a hardware problem.
Please help me, I cant get extra battery as of now as I am not at my place, I will be out for 2 more weeks atleast. Neither can I submit my phone for repairing until I am back at my place. Why is the phone not using the battery that is still there? Can anyone help please?
Replace battery, and if that doesn't fix the problem replace USB board/port.
Replace battery with a reputable battery. It will fix the issue.
