The overall calorific value of the mobile phone, 5v2a charging speed and power consumption in direct proportion, and then sad to urge the day the phone is not separated from the charger!!

The overall idea is very simple, according to the CPU use of the gradual troubleshooting!

Found Android.process.media CPU occupied has been high, first from him

Turn on the Phone settings option, select All Media Storage, and select "Clear Data"!

Restart after the discovery of Android.process.media CPU directly down, the notification bar display is scanning external memory, leading to the specific reasons for this is unknown, if you know tell me to learn!

See a friend said if the external memory content too will lead to Android.process.media CPU pull up, interested can be found a power consumption Android.process.media
