So a few days ago I bought a brand new Samsung OEM battery and battery life is indeed better than what I had with the old one but I have a question that's bothering me. My phone charges for around 1h40mins from 0 to 100%. Is this ok? I'm on Nemesis Reborn v5 ROM using Espheni Kernel, fast charging is disabled in Kernel Audiutor app and I'm using a USB 2.0 cable with my original charger that came with the phone. Should I be worried that it says it needs only ~1h40mins to fully charge or it's fine? Worth noting is that it actually takes a bit longer than that, somewhere around 2 hours. But yeah, I don't know why it shows such a low estimate and am worried that something might not be ok. Any ideas? Right now I'm doing this just in case: https://www.androidpit.com/how-to-calibrate-the-battery-on-your-android-device#battery-issue
