Phone 2 user here. Today I noticed battery dropped from 9% to 1% in one instant. Never happened before. Also I always charge my phone well before it touches 20% level. Battery life is good also. What could be the reason? My phone 2 is more than 2 years old. I had purchased it at the time of release.
Edit: it is more than 20 minutes since this post and battery is still at 1% after full usage. 🤔
