Hi, yesterday I discharged my s25 to 5% and then put it to charge, it was around 00, I disconnected from the charge at 8.00am 80% and at 1.30pm the battery was already at 7%, it's the first time this has happened to me and I didn't do anything strange, in fact today I used it much less than usual. until today very enthusiastic about the battery which has always taken me up to 00 without problems.
I am having the same issues. I have had the phone since 4 February and it was working fine. I set it on low power dark mode straight away to maximise the battery level and one charge was lasting 2 days. Now since 17 February, the battery is causing issues which I'm really disappointed with. I haven't downloaded anything new or used it more or differently than usual; if anything I'm using it much less. The battery just drains really fast. It took 2.5 hours to charge from 7% to 100% and I'm using the charger that came with it. The battery is draining super fast, in less than 4 hours it has gone to 58%. I have barely used my phone (images attached). When I first got it, I was watching Netflix for hours without charging it now I'm using it scarcely so I don't have to charge it constantly. I have switched my phone on and off. I can't see any updates but I have just read that there is an issue with fast charging. Last night I went to bed it was 30% and when I woke up it was 1%. I'm concerned because it was working fine before.
