iPhone 4 charging issue .

My iphone4 is playing up whilst charging(or not charging I should say)
It's gotta power sleeve which is also experiencing issues in charging.

I thought it could've been from overcharging but I have been told that apple product have a safety feature on their products that prevents this from happening.
I know Merlin has offered to replace batteries on iPhones with better Longer lasting ones and I am going to take him up on that offer,but I want to rule out any other causes or possibilities of the problem first .

Any one had similar problems?

Advice?

What is a power sleeve?

What are these issues you're talking about?

Power sleeve is a portable device that hold a full charge, so you plug it in when your out and about and it will recharge your phone.


Issues are I'm plugging in charger and connecting it to my iPhone and its not charging.

Have you tried another charger?

Sounds like your battery is dead. Book an appointment in the Genius Bar in the apple store. They'll probably just tell you to reformat it. Tell them you've done it and demand a fix.

Plugged iPad and iPod in with charger I'm using and none worked.
So I got a new charger and its working.

Power sleeve is still naffed though.
