SSo being on the go with a mobile device can be great for accessing any info you need, and sometimes your battery drains faster than you want it it, So a while ago I was on XDA-Developers.com and found a thread with info on calibrating your battery, Today I found a better version and I would like to share it with you
Now, I personally Suggest this:
Step 1. Charge the phone (turned on) for 8 hours.
Step 2. Unplug the phone, turn it off, plug back in and charge for an hour.
Step 3. Unplug it, turn it on for 2 minutes. Plug it in and charge for 1 additional hour.
Your battery life should increase dramatically
I also suggest wiping battery stats on-top of this, and you should see a battery performance increase of up-to 50%
