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?

I dropped a Nokia Lumia mobile down on to the hard floor when it was on. It fell down, but didn’t switch off and was functioning normally as intended. But after that incident, I have observed peculiar issue with the touch screen. If I touch somewhere it senses the touch somewhere else! I could believe that this is because I dropped the phone but this touch issue doesn’t happen all the time, also, if I lock and unlock the screen the issue disappears. So, my question is does this look like a hardware issue still or I can go ahead and claim warranty?

I have a Nokia Lumia 1320 mobile. Every time use the navigation app , it says that there is something interfering with the compass in Here Maps navigation app. What i feel is compass magnet is either stuck or there is some software issue. The location is almost accurate to the expected level. But this is awful experience to read my mobile saying that there is a problem every time i open the navigation app. Has anybody faced the same problem. Please let me know how to pin point this problem and if possible resolve it by myself. My Nokia Lumia 1320 has windows 8.1 OS with Cortana.
