I was wondering if the razr has anything built in that will prevent the phone from charging the battery if it is left plugged in after it reaches 100% power. My laptop had an issue were it would charge up to 100% and discharge slowly to 99% while it was still plugged in and then recharge to 100%, so it would do a ton of mini charges which hurt the battery life over time. I found a setting on my laptop that allowed for it to only charge when below a certain percentage (i chose 30%) and then when it hits 100% it will never initiate a charge until it hits 30% again. Any apps that manage this? or is this not an issue on the razr? thanks.
