Battery drains steeply in my xiomi phone
I bought a new xiomi phone online and was exploring all the features. I observed one heart breaking thing happening in my new phone. Whenever I turn on 3G and download, use internet, the battery drains like water in a bucket with a big hole in the bottom. I can literally see battery percentage going down. I am not exaggerating but this is happening. Bit my co user days that it happens only during some time. But why should battery drain so drastically? Is that a battery problem? Or something is wrong in phone hardware?
