My SE2020 has been getting worse battery time with each version of 14. Overnight when I was sleeping it would only lose 1-2% of battery over 8 hours. Last couple of weeks it loses 5% over 5-6 hours.
Another weird thing is when I go to charge it now the phone gets warm at times. It also charges fast almost as if it was a fast charger. This is with the standard 5w charger that came with it. This started with 14.2
