My BLU Win HD LTE has been behaving strangely about the battery.
The battery would discharge while its plugged in and the phone would randomly restart when the battery is below 20%. Same when I plug the phone in, the battery would discharge, the phone will boot up to a certain percentage, the battery would drain from there and the phone will turn off. The same cycle continues for some time, and then the phone charges as normal.
Today, however, something different happened. I plugged in my phone at night and saw the battery at 28% this morning. Curious, I opened the battery monitoring app I noticed that the battery charged up to 100% normally, then dropped down to 40-50%, then climbed back up to 70% then again fell down to 28%(which is when I unplugged it) and all this happened when the phone was connected to a 5.2V 2.4A charger.
Its been a few hours since I woke up and I am using the phone heavily since then. Mobile hotspot on, watching youtube videos, playing graphic intensive games, and since the last 1.5 hours, the battery remains at 28% (it still is)
Any idea how to fix this???
I'm on windows 10
