“Fix a phone that won not charge properly”
phone doesn’t charge
Do-It-Yourself USB port fix
The quickest, easiest, and often most successful solution, is to do a little DIY repair on your actual hardware. The problem is often that the metallic surfaces inside the USB port and the microUSB charger are not making good contact, either through a manufacturing defect or because of the continual plugging and unplugging of the charging cable.
All you need to do is shut down your device, remove the battery if possible and use something small, such as a toothpick, to ‘lever up’ the little tab inside the USB port on your smartphone or tablet. Do so very carefully and gently, then reinsert your battery and plug it in again. Nine times out of 10 this is all that is required.
The flimsiest part of a charger is the cable, not the adapter that plugs into the wall socket. Apple users are particularly vulnerable here because Apple’s proprietary (and expensive) Lightning cables appear to have a life expectancy of around 15 minutes. But all cables have a tough life, and endless flexing and curling can take its toll. Substituting a random USB cable for the one that came with your phone is another shortcut to an unenjoyable charging experience.
The easiest way to diagnose a faulty cable is to try a different one and see if that works properly with your device. If it does, you know the original cable was at fault. If it doesn’t, that’s another potential villain we’ve ruled out.
Diagnose a adapter
If the cable doesn’t seem to be the problem, check the wall plug adapter – especially if it’s one where the charging cable can be removed. We’ve encountered issues in multiple chargers where the USB port becomes a little loose after endlessly plugging in and unplugging the cable.
Also check whether the same charger/cable combination works on a different device because this will help you eliminate the possibility that it is your device at fault, rather than the cable or charger. You should also make sure there isn’t a problem with your wall socket.
the battery Replace
Batteries don’t last forever, and after a couple of years they start to struggle to hold a charge. The more often you discharge and recharge them, the sooner they’ll need replacing. If your battery’s busted after just six months, it’s probably faulty and you should make a warranty claim for a free replacement, but if the battery’s older than two years, it’s probably approaching the end of its lifespan.
Some defective batteries are easy to spot because they start to bulge or leak fluid. If nothing like that is obvious from the outside, remove your device’s cover and inspect the battery (if you can; some devices have sealed battery compartments).
