Why a phone isn't chargingThis issue could occur in a variety of ways. One, your phone could be plugged in to a charger but simply won't charge or charging is extremely slow. Here are some of the solutions you need to try.
Do-It-Yourself USB port repairOne of the easiest and often successful way to resolve this problem, is to repair your phone's USB hardware yourself. The problem is usually that the contact made between the microUSB charging cable and the metal surfaces within the USB port isn't the best, either because of a manufacturing defect or caused by the continual 'plug and unplug' process of the charging cable. Simply power off your device, if possible, remove the battery and then using a small tool such as a toothpick or piece of paper, lift up the tiny tab within the USB port on your phone or tablet. This should be done very carefully and gently, reinsert the battery once again and the plug it in to your charger. Nine out of ten times of this method, is all that's needed.
Remove lint and dustIf your phone is often kept in your pockets, then lint could be the cause. Many times unreliable USB charging has been found to be due to the lint or candy from the pockets or handbags, we carry our phones next to. This can be resolved by blowing out the irritants using a can of compressed air, which will get your USB charger functioning again.
Use a different cableThe most vulnerable section of a charger is the cable and not the adapter that's plugged into the wall socket. Though some charging cables are mostly durable, the continuous curls and flexes can take a toll on it. Swapping a typical USB charging cable for your the charger that originally came with your phone is one of the easiest ways to enjoy a horrible charging experience. The most obvious way to determine if a charger is faulty, is to switch your cable with a different one. If it works, then the original charger was faulty.
Charge from the right sourceAs you are already aware, charging directly from a wall socket is way faster than charging through a laptop or PC, due to the fact that USB ports on PC's aren't as powerful. A wall socket delivers twice as much power as that obtained from a USB port, with up to five times power delivered from fast chargers, which is equivalent to much, much faster charging in comparison. So in case your USB connection is via laptop, then that may be the culprit. If however your wall socket is delivering as much as you'd expect, check that its right for your smartphone or tablet. For instance, if you are using a charger from a different phone, it might not give your phone the right amount of battery juice.
Replace your batteryThe efficiency of batteries isn't a lifetime guarantee. After a while thanks to the endless battery discharging and recharging, it starts to struggle to hold a charge and as a result you a need for a replacement may arise. If your battery is acting up after only six months, then you should claim your warranty and get a free replacement, but in case its older than two years, then it may reaching the end of its lifespan. Some of the ways you can spot a defective battery, is if it starts bulging or leaking fluid. Have you been plagued with a smartphone that isn't charging properly?
