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!

According to that graph, you had the screen on 4 1/2 hours and only off 1/2 hour. Heavy screen use is going to eat into the battery. Also, the S25U hasn't learned your usage patterns yet to apply any algorithm to help battery life.

I understand that, but if you look at the end of the graph, the battery percentage just drops like a stone! Not to mention it was cool to the touch before and almost uncomfortably warm to the touch

Here it is with the drop off even more visible. The battery life shouldn't be 5 hours of YouTube

I think you are overdoing things in the phone

I mean, I'd expect a 1300 dollar premium smartphone to be able to handle 4 hours of YouTube without draining the battery, but yeah it does kinda seem like a big ask now that you mention it. My Pixel 8 does a full 8 hours without issue though, so maybe the S25 just has worse than terrible battery life?

I'm getting great on screen time and I have the display on the highest.

Yeah I can't match that at all on mine. I need to top up halfway through the day

[Faith7777]

Oh no, that's terrible! I would be very frustrated. I'm just putting the charger on mine now. I got crazy on screen time today. I just took another screenshot to show you. 22hr 44 min since charge out of the box last night.
I think you should send it right back. I hope it all works out for you, take care 😊

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