# Cell Phone Battery

I'm sure you've experienced the nervous moment when you have something really urgent that needs to rely on your mobile phone for calls and at that time your phone battery gone flat. Flat battery with no charger is the worst case. I have experienced once, therefore no matter how, I always keep my phone battery at its optimum. For my practice, as long I'm at home, my phone will always attached to the electric socket.

But can't avoid that the cell batteries one day will goes weak and need frequent charge. But I really feel bad now, cause my new smart phone battery is not weak yet, but it caused by a few time dropping and it become loose now. It can't connected well and always auto shut-off.

I think is time I get an extra battery or should I send it back to the dealer for checking since it still under warranty.
