Question iphone 6 battery

[wodie88]

My iphone 6 wasn't charging past 3% so I got a replacement battery and we changed it. It was working well for about 4 or 5 days and it dropped from about 1.5m onto the hard floor (in a crap case because I was trying to get a replacement for my lifeproof case). Since then it has gone back to the same problem except now it won't charge past 1% and if I leave it on the charger, it stays on but if I try to use it while on the charger it just turns off.

Can someone tell me what is happening??

Thanks

No way to know what that is happening without looking at it, something could have been dislodged when you dropped it is the most likely thing.
