are there any battery cases available which protect IPhone the way like
otterbox defender case does?
I mean I would like to have the whole device covered and use external
battery or battery case when I am out.
Another question is are the battery cases able to charge the Iphone to
full capacity (I mean 100%)?
I know this question may sound stupid, but I got an external battery
(not battery case), and it charges Iphone just by 20% and then te
charging process is done.
I would be very grateful for your advice.
Thank you in advance.
