Am I overcharging my phone?

> **Possible Duplicate:** > [Does constant charging harm my Android cellphone?](https://android.stackexchange.com/questions/1020/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.
