Am I overcharging my phone? Possible Duplicate:
  Does constant charging harm my Android cellphone?  




I am using my Xperia Active for application development. Given that scenario, I obviously have the phone connected to the laptop most of the time since I want to be able to easily test my app on the device.

The thing that's worrying me is that when I go to Settings > About phone > Status, the Battery level is set to 100% and the Battery status is set to Charging (USB).

Am I overcharging my phone? Is this bad for the battery's health? If yes, what do I do about it? I use this phone on a daily basis and I don't want the battery's performance to be affected by my development cycle.
I doubt it. The charging circuits should be smart enough to avoid this. More likely they aren't actually charging your battery but directly powering your phone from the input while leaving the battery mostly alone.
