Samsung Galaxy S26 Ultra overheating, lagging & battery drain issue

[TopGAlex]

Hi everyone. I recently got a Galaxy S26 Ultra (512GB) and I’m honestly disappointed with the performance so far.

My device heats up very quickly during normal usage like:

WhatsApp Business

Social media scrolling

General multitasking

Even general use 

The phone also feels laggy/stuttery at times and the battery life is much worse than expected. My previous S24 Ultra actually felt smoother and cooler under the same usage.

Things I already tried:

Updated software

Cleared cache

Optimized apps

Removed case during use

Restarted device multiple times

Still experiencing:

Warm/hot back panel

Fast battery drain

Performance drops

Phone not feeling “flagship smooth”

I’m starting to wonder if my specific unit could be faulty or refurbished. Has anyone else experienced this on the S26 Ultra? Any fixes or should I take it to Samsung for diagnostics/replacement?

Thank you brother I thought maybe the phone is just like that

When I charge mine to 100%, I can use it for 22 to 24 hours without any battery saving restrictions."

If making calls can take 2 to 3 hours still on 100%

Mine is charge it twice per day and on some days even 3 times but average days uses 190% for 6-8 hour screen time
