Power Problem
 

Is this the right place for me to gain some answers for my questions?

I have power problem seriously for my phone. When you are outside, the battery does never stay live for one day. You know, smart phone wastes a lot of battery, big screen, automatically pop up app, etc.

I was think about buying an external battery pack for my Galaxy4. But it is hard to decide which one to buy. I amazoned this particular product but found too many choices outside..
Any advice on picking a particular one? tks.

I would suggest you to go to android forum: http://www.androidquestions.org/forum.php
Probably you can find battery on ebay.
