The top cap is now pretty loose and comes off if i put it in my pocket

There is a rattle in it now but it doesnt seem to be affecting the battery in any way

Probably stick with what has worked

Although the battery is fantastic its not very protective

That said i recently started having battery life problems with my iphone where the battery would quickly drop from full charge to almost no charge in just a couple of hours with minimal 3g or wifi use

I realized the battery inside the iphone was starting to die and when i looked into getting a new phone from work it was obvious that it would be more trouble than it was worth or i might even end up with a worse phone than my current iphone 4s

The unit is 2 piece and the lower half fits so tight that its almost impossible to get it back off
