If you want to charge your phone real quick

1)Turn on airplane mode and charge your phone. 2)switch off your phone while charging.

3) Charge using your regular ac charger(we all charge via usb a lot..we forgot the chargers).

4) Dont charge your phone whens its hot(every phone becomes hot even the iphones wait for it to cool a bit) it'll definitely improve charging.

5) Switch off/Restart/Reboot your phone in regular intervals(once in two days) it might actually dish out the cache memories and improve battery percentage(especially androids).

6) Buy a phone which has quick charging feature(Every new phone except the iphones).

7) charge using wireless charger (if your phone supports it) its real quick medium.
