I am unable to use my phone it will not hold charge and dies quickly. I will be receiving a new phone tomorrow however I want to wipe my phone for my personal benefit. I have two questions; first will it wipe the system or just my personal files, and two I will be using another users battery will damage be done to the battery? Also if you know of any other file wiping tools for non rooted droid user....Any advice is appreciated, thank you

This weekend I did a factory reset on my Droid Incredible, asking it to wipe everything. (The phone had been slowly turning into a brick and this was the solution.) After it finished, there was still a lot of my personal information on it, not just in the memory card, but also in the main memory of the phone. I had it expected it all to be gone.
If I were going to sell or give a phone away, I would first do the factory reset then hook it to my PC, change the USB connection type to disk drive, scour for personal info, overwriting and
