My phone Nokia Lumia 830 stops charging to 80%-81%. I don’t know what is the problem. Is a software or hardware problem? -I have replace battery to a original 2200mAh. -I charge the phone with a Baseus charger : Output– 5.0V == 2.4 A

Hi! There are a few thing you can try: first let the battery drain all the way to 0% (or until it shuts down), then plug it in and see if you get any further than 80%. Another thing to try is a soft reset (this won’t affect your data) while the phone is plugged in: Press and hold Volume down and Power until the phone restarts.

The problem is the replacement battery is not original, most surely you bought it from Ebay/Aliexpress and it looks like it’s original but when you pay $5 one thing is sure: it’s an aftermarket non original product. For this reason, the Lumia phone doesn’t recognize it as original and for safety reasons, the phone it’s programmed to not charge the battery more than 80%. Some aftermarket batteries won’t have this problem, while other will. There is absolutely nothing you can do to charge the battery more than 80%. The internet is full of people who have no clue but suggest tons of things, resetting the phone, updating the software, draining the battery, etc. etc. Nothing will help. DO NOT fully discharge you battery listening to internet ’experts’, fully draining the battery is the best way to ruin it.
