when the charge is above 50%, it doesnt auto shutdown but when i play music or surf the internet at below 50%, it automatically shut's down and my batery heat is only 40%(?)and doesn't reboot.Has anybody experienced this?
Hey Addak,
Please provide info about your ROM and kernel, so we can check if there any issue or just suggest another one
Regards

Try some battery calibration, provided by zimmerAndy in Feralab´s Discussion Thread
HOW TO -
1. U need to drain your battery untill it went 0%, it will switch off ur phone for sure lol... than try to turn it on untill it wont even start/vibrate....
2. Now after completely draining your battery...connect it to the charger (To the socket charger not to the computer - we needs to get full voltage)
3. When it become 100%, do not disconnect the phone from socket wait untill 1 to 2 hours....(u can start your phone BUT DON'T USE IT )
3a. if your battery drained till its connected to the charger in 1 to 2 hours disconnect your charger and charge it again untill it gets 100% and repeat it untill battery stops draining on charging. than continue to the step 4.
3b. if your battery is not draining in this 1 to 2 hours, than go with the step 4.
4. Now the phone is fully charged disconnect the charger , reboot into xrecovery and wipe battery stats, reboot your phone, when lights gone off remove battery from the phone, and put it back and power on the phone.
5. leave it on charge and charge it untill 100%, disconnect the charger and reboot the phone, after power on
5a. if your battery percentage is 100% u done with the battery caliberation.
5b. if not than charge it again and reboot and check for the percentage, repeat it untill u get 100% battery on power on.....

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...
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
First of all it wouldnt charge past 99%, And then, after one hour of standby it went down to 88%!!
Cm7 official stable release.
Me too no pass 99% :S
Try to download a "battery caliberation" app and do that, also burn it to 0% and charge to 100% while the phone is off..i heard that this might help.
Now i will flash Nottachtrix and do what i wrote Good luck man !

The charging thing is something that is (seemingly) well known throughout the community. I have tried to do the calibration, but it doesn't seem to work that well (at least for me). There is a thread around here somewhere for fixing the issue. I just have never tried it due to work reasons.
The charging past 99% is a known issue with most of the ROMs. There is a thread in here that takes you step by step to get it to display 100%. Basically....
Charge the phone long enough to where you know it should be at 100% even though it is still displaying 99%.
Power the phone off while it is still connected to the charger and then pull the battery.
With the battery pulled, power the phone back on until you see the battery indicator with the "?".
Put the battery back in and reboot.
You will then see the display of 100% with the phone still connected to the charger. The only downside is that as soon as you disconnect the charger, it will drop back to 99%. I have done this multiple times.

I read good things about it.
First of all, use Wipe Battery Stats function at recovery.
1 - Discharge all your smartphone battery;
2 - Connect it to the wall charger and don't turn it on;
3 - Wait till it shows you 100%;
4 - Remove the battery, wait 10 seconds, put it again and keep it turned off;
5 - Wait 30 minutes, keep it connected to the wall charger and press power button till it turns on;
6 - Wait 30 minutes, keep it connected to the wall charger and use Battery Calibration App to calibrate it;
It doesn't make any sense, but sometimes, after step 5, i prefer connect it to usb port in a laptop or computer and wait one hour. It always worked with me.
It might solve your problem .
Wiping battery stats does nothing. it just takes a few charge cycles. If it's a new rom and it's draining fast it's also cause you are probably playing with it a lot

It could be a bluesleep problem... Install CPU Spy App and look if it goes into deep sleep mode. If not, there is a fix for it.
Aside from the OP's issue with the battery draining quickly, why does it matter if it doesn't show 100%?
Nothing can ever 'really' be 100% charged because as soon as you take it off mains it is instantly on the battery at lets say 99.9999%...
As long as the battery doesn't drain quickly I couldn't care less if its showing 99 or 100%.
The problem was that it was draining very quickly to smt like 50% and then it would hold longer...I just wiped everything, restored a neutrino 2.7 nandroid backup i had, flashed the jug fix v2 and now it shows 100%
hi guys! i'm running cm7.2 on my su660 (it's a kang build which is ported from p990 official CM build). and i have a problem on charging the phone. when the phone have 10% of battery left, i plug in the charger, the phone show the charging symbol . but when i leave it sleep and come back after 'bout 3 hours, it still show 10%. but the voltage in sparepart is aproximate 4200 mV. so the battery is fully charged but the rom didn't regconize it. but then after some minutes turning the screen on, the rom show that phone is fully charged. so i guess that the battery percentage counter doesn't work why the phone is pluged in and sleep. so this is a rom issue? can i fix it myself?
PS: sorry for my poor English because i'm not a native English speaker. i'm from VietNam. i tried my best to explane my case. hope u can understand me!
If, after rooting or more likely that case after flashing a new rom, you often have battery reporting errors, and re-calibrating the battery along with some steps I will outline for you below will ensure that your battery is getting a full charge, and the battery reporting accuracy is right on. As far as power cycling, I don't know that it does much good. I run my device in performance mode all the time, and with a CPU overclock of 1.25GHz and various tweaks, I have about a day an a half to a day and a quarter of full runtime from my battery. This is with moderate to heavy usage (calls, emailing, text, gaming, web browsing, etc.) so you should have no problems getting acceptable battery performance after following these steps:
1. Take the case off your device (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your device to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. Write it down.
My Atrix 2 was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your device completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%.
10. Let it sit there charging for 2-3 hours (or more).
My phone wouldn't charge past 10%, but yours might. The numbers don't matter much as the phone is definitely getting additional charge that could have been lost while flashing ROMs, etc.
11. After 2-3 hours (or more), turn the phone on while holding the volume down button and get into CWM (if installed) or use Rom Manager (is device is supported).
Do not disconnect it from the charger still!
12. Wipe battery stats in CWM, reboot.
Do not disconnect it from the charger still!
13. When the phone turns on, go into Battery Calibration app again and look up your MV numbers -if you were like me, they should be significantly higher than before. After this whole process I had 4351MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
14. Before going to sleep - Install Watchdog Task Manager Lite from the market. Go into it's preferences, set CPU threshhold to 20%, check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20% as well.
Do not disconnect it from the charger still!
15. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.
Go to bed, let your phone sleep too.
16. Success! Next morning check where your battery % is at and if you followed the instructions correctly / got lucky like me, your battery life should be 90% or more.
I went to bed with 98% and woke up to 94%. So, I consider this mission a success.

It is my first post and my English is not very good, so if something is wrong, please correct me.
Some users have reported that when the battery reached 15% of android, mobile phone alerted 'low battery' and battery level drops to 1% and the phone hung up.
But when he began plugged the charger from 15%. And that was not the case for lack of calibrating the battery, has more to do with 'Custom ROMs' and 'kernels'.
1. The solution is simple, just let the battery runs out (15%) and mobile off.
2. Then turn on the phone one more time, so that you make sure that the battery died.
3. Hold the phone off and then remove the battery for about five minutes.
4. After that put the battery, switch on the phone again and put the charger before it shut down. (The mobile will shut down anyway.)
5. Remove the charger and, even with the phone turned off, reconnect it.
6. Wait for the screen 'battery charge' appear.
7. Wait a few seconds and turn on the phone.
8. If everything goes well as my mobile, your phone will start charging from 1%.
9. Complete the charge, disconnect and use the mobile phone until your battery runs out.
10. And the issue is resolved.
PS: You may need to repeat the process once more.
:fingers-crossed:
___plesse if it works (or not) TELL ME.
Thank YOU.

This will work if the problem with the battery is the power meter. These steps are similar to the ones recommended by Sony Service :good:.
Here is how Sony says to do it:
1. Charge the phone to 100% using the wall charger.
2. Remove the power cable and the battery for 10-15 minutes (no power al all to the phone).
3. Return the battery and power up the phone. The battery meter should have dropped by about the same magnitude as your drop off (15% using your example. It may not be exactly the same number but should be about the same.
4. Charge the phone to 100%.
If you have to do it more than once, you probably didn't do step 2 long enough.
use battery calibrate (instruction included). get it on app store. or if you unlocked bootloader and have CMW, just wipe battery in CMW.
none of this solutions isn't working for me
