A52s battery stuck at 100% for too long

[vukman02]

Hello everyone. I have a question for you all. So, got a new phone a few weeks ago and I've noticed lately that after I charge it from, let's say around 10% to 100% and unplug it a few minutes after it reaches 100%, it stays on 100% for longer than it should. It stays on 100% for at least 20 minutes of active screen on use (no matter how I use my phone it stays on that 100% for quite some time), and after that it looks like it starts to drain normally. So my question here is: Can the battery calibration be off on such a new device?

Thanks in advance.

I just bought a new battery. When I first charged it to 100%, it took about 15 minutes to fully charge. Then when I calibrated it, the charge slowed down a bit when it reached 85%, then it fully charged immediately when it reached 100%. It's not like when I first charged it. Is that normal?
