One of the most common repairs we are asked for is the Galaxy S III charging port. This is a repair the we can’t do because the chances of it re-breaking are very high.
Zezs There is a great work around and it will keep your phone going. The first step is to buy an external battery charger for the S III. Look below.
Then you buy a couple of batteries and then you can always have a charged battery. When the one in your phone dies swap it with a charged one from the charger. No more battery issues.
