Why isn't my battery charging all the way? (Lumia 640)

[Windows Central Question]

Recently I replaced my Lumia's battery because the original one was slightly damaged and it drained quickly. However, since I have started using my battery I have noticed two major issues: it doesn't charge fully at night and the battery life is almost as bad as the old battery. Every morning I wake up and the phone is at 81%, it literally will never charge above that percentage anymore. Nonetheless, it dies just not quickly as the old battery since I literally am losing a fifth of my battery life. Any solutions on how I can fix this problem? I'm updated to Windows 10 Mobile and everything. Not sure what could be the issue here... I've also taken steps such as turning battery saver on and stopping background apps but battery life still sucks.

Was the replacement battery a factory replacement?
Without knowing what type of damage was done to the battery perhaps something has happened to the phone also.
My experience with charging or battery bugs usually ends with a hard reset.

Also aftermarket off brand batteries can cause problems.

Good luck there.

Have you tried taking the battery off charge in the morning then putting it back on charge after a few minutes? I wonder if struggling to recalibrate the battery charge status so it *is* actually* fully charged but the status thinks it is only 81%.

I'll have to try that one out!

It wasn't factory replaced so I didn't get it straight from Microsoft, but it is a Microsoft brand battery. I factory reset my phone, so I have yet to see if the phone is able to be charged past 81%. It should be at that point soon though, thanks for the advice!

Hmmm... I factory reset it and now it won't even charge past 67%. This is an issue...
