I know that going to Airplane mode can be useful But is there any way to charge phone faster?
Turning it off first. Then there's no possible stuff draining energy while it's charging.
Be sure to charge via AC. Charging via USB is much slower.
There's a small chance that the charger you have doesn't draw power as fast as your phone can take it. A charging brick with a slightly higher mA rating might get you some quicker charges, but I think it's unlikely (especially if you're using the charger that came with the phone).
I saw this a few weeks ago which, if genuine, looks pretty good. I am still sceptical however but would be nice to see if it is successful.
Use DU battery app. By that my phone charges abit quick.I have noticed it alot of times
