I've had the s24 ultra for a few weeks now the battery life is good i haven't had issues with that so far. I typically use an acefast wire that tells me the charging input for whatever device and when i charge my phone it ranges between 15w and 30w until it reaches full. a few days ago i noticed it was stuck at 8w and wouldnt go above that and the phone wasn't charging well i think it charged maybe 5% at most in half an hour or an hour. i tried different wires (not acefast) and had the same issue then i used that acefast wire on another device and it charged that normally. when i woke up i tried again to charge the phone and had the same issue. restarting the phone seemed to remedy it since it went back to charging regularly after that. it happened again today. both times it happened the phone was around 40% when this was happening not sure if that's a coincidence or a pattern.

i don't know if this means the phone or battery is faulty. i don't want to wait too long until past the point i can return the phone if there is a fault. i also plan to keep this phone for the next few years i don't want to have to deal with this on a regular basis from past experiences any issues i've had with devices only get so much worse with time i'd rather not have to deal with this especially if it gets worse over the next few years.
