A friend's iPhone 5 battery was depleting too fast and she still has about 2 months before her mobile contract ends. So what could better than a quick and cheap fix?
A bit difficult at first, especially the part where you have to open the screen of the phone, but thanks to the opening tool that comes with the package, it actually make a big difference. One has to be patient and apply constant pressure as how the instruction video said.
Perhaps, do note that on some cases, you may have to remove the screen protector cos it makes the suction cup less effective.
