S25 Ultra overheating and poor battery life

[S-Pen-Diehard]

I had this issue on my S24 Ultra in late summer, so I decided to trade it in for the S25 Ultra and it's happening straight out of the box. The phone gets really warm and the battery starts dropping at like... 1% every minute or two. Restarting the phone stops it for a little while but then it keeps doing it. I've included the battery graph, and you can see it just randomly curve down. Does anyone know what could be causing this? My Pixel 8 gets better battery life at this point!

Edit: 90 minutes of being bounced around support agents and I'm done. I'm returning this piece of junk and recommend anyone who's experiencing the same thing to do the same.

Hi, so my second day with a full battery actually I want a day and a half I think I did not get close to the 9 hours. I'm don't know if because I literally was on my phone all day and I get the full 9 hours and I was at work yesterday so I wasn't. I'm going to recharge again and then see what my third day on a full battery comes to.

Yeah but you're using 90% with less than 6 hours of screen on time how is that even remotely okay

I'm having very bad battery life too. It's like half the battery life of the S24 Ultra

Me too

I can't even get more than 4 hours of on screen time I'm thinking about returning this device and never looking into Samsung ever again

I'm trying to set my phone up from zero instead of transferring from my Pixel. From enabling GPUwatch in Developer Options, the phone seems to use an extra 25-30% of CPU usage despite not doing anything, all apps closed in the app drawer and sitting on the home page. If it starts overheating again I'm doing the same

I feel like that is entirely way too much work for something that should have been addressed pre launch, hopefully tomorrows update will fix it

Same here. Battery is horrible. My s21 was so much better

It heard a 15% overnight drop. This is just terrible
