Battery problem
 

So I was playing with my friend on a multiplayer game and my tablet informed me I had only 15% of battery percentage left, so I charged it and watched a 6 minute video and in my notifications it said my battery was fully charged and it even says it on the battery perdentage thingy but I noticed that itgoes down a LOT quicker every minute it goes down by one percent. Does anyone know a fix to this?

Sorta had the same problem last night but I had my iPad charging for about 3hrs and it stayed at the same percentage the whole time.Its charging very slow now.

Yeah but mine charges insanely fast it was already at 100% in 6 mins. But its going down by 1 percent per minute as mentioned above

If you're brightness is up too high it will do that but I'm sure you know that, other than that I don't really know what to say that's helps other than restarting it.

Apps that are running in the background can be a problem. Make sure you don't have a ton of tabs opened as well

I keep only one tab running at a time but two if II have homework the first is for the answers and the last one is for a game. XD

You don't use your electronics on charge as that can damage the battery. The only way to fix it is to buy a replacement battery

Ok?

Probably a problem on how your phone reads how much battery percentage you have. I suggest charging it for 3 hours and see if it goes down as fast

But before that try restarting your phone

Batteries become worse over time with too much charging while full etc.
(My old iphone 5 can stay on for 10 minutes before it dies while it's on 100% lol)

Batteries only become bad when its old, NOT when you charge it 'too much'

Most phones come with protection that stops damaging from charging when full.

I had my phone in the charger close to 24/7 cus I gamed on it. That combined with it being 2 years old pretty much killed it

Try completely draining your battery then giving it a full charge.

How old is your tablet?

Has it sustained any damage?

Ok I'll try to do that.
