Hi
I am contacting you as the last hope to have something worked on for my streak regarding the extended battery not getting detected. I have tried all the calibration apps but still no luck.
i have recently purchased this battery and there are issue i am facing regarding the battery mostly regarding the reporting. its the android 2.2 operating system that is the issue, with the 1.6 android it is working perfectly fine as i have tried it on my friend's streak which is running android 1.6 and on his phone properly detects the battery and reports the battery properly and it is dead when it is reaching 0 % unlike mine which works for 18 to 20 hrs when the stock battery meter shows 1% . The Mugen app doesnt help regarding the calibration as i have used the app and have completed 5 charge cycles of 10 - 12 hrs without break. it is mentioned not to let the battery drain to 0% but since i dont have the readin of the battery i cant say whether it is low or not as the system meter shows 1%
The issue that i am as follows.
1. the system battery meter doesnt show the correct reading.. it shows the battery to be fully charged when the
battery is fully charged tht is at 4211 mv and after i take the charger out and use the battery it shows properly how a normal battery shud decrease and then goes and gets stuck at 1% and in tht 1% the phone will work for 18 to 20 hours..so it wierd as u never know as to when the battery would die and this is wht happenned once the phone suddenly died after being on 1% for 17 hrs
2. no other app works properly cause of this. i have tried using battery left and battery monitor app ( which calculates via voltage ) however what happens is that the app shows a correct reading until the stock meter goes to 1% but once the stock meter reaches 1% the app gets stuck at the reading it showed when the stock meter reached 1%. And if i turn of the phone and take the battery out and put it back in the stock meter shows 50% battery left and the app starts working again and once again when the stock meter reaches 1% the app fails and then again if i take the battery out and put it back in again i get 50% battery on the meter. i have checked on forums and it has been concluded tht this happens when the battery made is not a single battery of 4800 mah but 2 or 3 batteries combined together to appear as 4800 mah.. is that the case with this battery.
3. the third issue is of charging back again... after the stock meter stays stuck at 1% and the phone works for 17 to 18 hrs if i put it back on charging the stock meter still stays stuck at 1% and doesnt move forward at all even though the battery is getting charged...again if i take the battery out and put it back in the battery will show the amount it has been charged.
Any help would be appreciated.
I have had Transformer Prime for over a month. its rooted and never gave any battery issue. i have installed Battery Booster app to monitor battery percentage and temperature and also to be notified when battery is fully charged so i dont over charge it and damage the battery.
recently my prime shuts down with 30% battery still remaining. i have to charge it to get it back on. Once i charge it for 5 - 10 min it turns on showing 34-35 % battery life. ( Battery Percentage checked with Both Battery Booster app and built in Device settings )
Kindly Help.
Wipe the battery stats, it has the "dead" state at 30%.
Wipe the stats, run a full cycle or two and it should be good to go.

Click to collapse
I have already done that , and now have my fingers crossed , will update once i reach 30% or Below.
Ok . wiped the battery stats , charged it to 100 % and no problem faced after that. took 5-6 pics with flash on at 1% battery remaining, still didn't die.
Good to hear!
You might want to change the thread title by adding solved at the beginning or end.
If you're not sure how to, if you edit your first post and go into advanced mode, you can then change the title.
i hv bnattery problem for 3-4 month
still cannot solve the battery problem
i think i have done some wrong steps in the battery calibration
when my battery is fully charged in a battery changer(charger for battery only)
when i put the battery into the phone, it's shows that there is about 30% of battery
when i further use the battery, the battery level rise (without charging!) to 100 then drop to 0 and turn off
the time that the phone can use from 100% to 0% is quite short
when every time after charging, the battery level is 100%
it won't charge to the "real" full battery level, ie ~30% (SORRY FOR MY POOR ENGLISH)
how should i calibrate?
i used the battery calibration app, but no use.
Charge to 100 then use battery calibrator from market very simple

If your recovery is ClockWorkMod, then there is an option to "Clear Battery Stats". Just try to see whether it helps.

It's a few days late, but battery calibration is unnecessary on modern batteries (Lithium). All the apps do is delete a small file that records power usage, they do not affect battery life in any way. This file is cleared automatically (by the system) when the phone is fully charged.
Further, full charge/discharge cycles will actually have a net harmful effect on your battery life. A lithium ion battery has a limited number of charge/discharge cycles it can sustain before becoming more effective at being a paperweight than powering anything. The full cycles you are doing simply eat into the battery's overall life expectancy.
For instance, it is better to charge from 50% to 100% multiple times than it is to go from 0 to 100 once.
Personally, I would just replace the battery.
I would suggest u to calibrate the battery in the clockworkmod recovery too
if this wont has any effect take into consideration that your battery might be damaged
i faced this problem one year ago with a galaxy spica the battery was shown as full and after a restart it was almost empty and calibrating the battery did not had any effect
so have a try and report afterwards
If, after rooting or more likely that case after flashing a new rom, you often have battery reporting errors (as mentioned above), 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. 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.
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.

Many users have problem regarding the battery gets discharged 90% to 20% in few minutes.So here is the simple solution...
Callibrate your battery using battery callibrator...https://play.google.com/store/apps/details?id=com.nema.batterycalibration
1.first charge your phone upto 100%.
2.click on callibrate.
3.unplug the charger..
4.allow battery to discharge(Don't use too heavy app to do it just normal use)
5.after discharging again fully charge the battery..
6.Your Battery is now callibrated...
When I charge my android to 100% the battery discharge so weird, it discharges from 100% to 85% the 1% takes 8 min and when it reaches 85% to 75% the 1% takes only 2 min and from 75% to 0% the 1% takes 3 min, so I think the battery indicator is the problem because the battery is good and still new I'm pretty sure about that, so can you help me with this problem and how to fix it.
Thanks.
