i've actually ahd the same thing happen to me on more than one occasion already. never happens with the stock battery though

Good luck

I purchased a Mugen battery for my Incredible 2 when I was using it and as mentioned in the above comment, the battery life does last longer per charge. However, that only last for the very short life span of the battery. The Mugen slim battery started lasting less than the stock battery at about the 3rd-4th month.

Well thats disappointing, wouldn't be worth the price if it starts crapping the bed 3-4 months in

Correct me if I'm wrong, but I thought this was debunked by Google.

What I have noticed form deleting the battery data was that the battery % is more correctly depicted. It definitely does not improve battery life, that's for sure. I always wipe it when I swap batteries, once when I didn't I noticed the % depicted in the status bar was about 4% more then it actually was.

All I know is that I was having the issue of it dying around 10%, after I calibrated it the problem stopped.

Interesting. So what are you doing for calibration? Just using a calibration app? Because I'm having the battery dying at 10-15% issue too

You need to calibrate your battery. Or rather the battery bin file that android uses to measure your %.

Charge to 100%, download and install the battery calibration app. While you are still plugged in at 100% run the app. Take off your back cover (so you can pull the battery quickly) and click on the button that says Calibrate battery. This will delete your batterystats bin file. Immeditely pull the battery.

Wait a minute, then put the battery back in (Leave the phone off). Plug in charger and allow it to charge to top off the battery with the phone off for about 10-15 min. (If you notice the little LED that is generally orange when charging at the top of your phone will turn green when fully charged).

Next unplug from the charger and turn on your phone. Your phone will create a new bin stats file on boot and start recording your battery drain time.

Use your phone as your normally do until it dies at 0% completely.

Next connect to your charger, allow this to charge for 5 min while off. Then turn on the battery while connected to the charger and the phone will then record your new battery charge rate. It is important that you leave your phone on when charging this initial time.

You need to do this anytime you change your battery or your ROM.

Also to those people who say you cant train or calibrate a these types of batteries you are correct, you are calibrating the statistics android uses to monitor your charging and discharging rates not the actual battery.

Your phone detects low battery voltage and turns itself off based on the recordings. This does not actually extend your battery run time it simply gives android a more accurate point of measurement.
