Why battery drain so fast?

A

AC Question

Hello. I have a Lenovo phone and I am having some problems. I recently charged it with a samsung charger and it charged normally. The next day I used my portable charger and it suddenly charged from 20% to 90% within 5 minutes. Ever since then my battery would drain very quickly

When it drains quickly, go to Settings/General/Battery. Take a screen shot. Tap the graph and take another screen shot. Post them here. (See How To Post Screenshots on Android Central.) (Please create a free account here, so you can continue the discussion in this thread.)

There are a few possibilities as to why the battery is draining so fast (using a Samsung charger isn't one of them), so instead of throwing all of them at you, if we see the screen shots we may have a better idea of what's causing your problem.
