I recently pre-ordered the Samsung Galaxy S25 (Base Variant) and bought it offline from a Samsung Store. Right from the start, the battery life wasn’t great—I was barely getting 2 hours of screen-on time per charge. But I knew that Samsung devices take some time to optimize battery performance based on usage patterns, so I gave it a fair chance.

Unfortunately, even after weeks of use, things haven’t improved. My phone’s battery drains ridiculously fast, and I have to charge it multiple times a day despite using it minimally. My mobile hotspot is on most of the time. The battery performance feels abysmal. I’ve attached my screen-on-time screenshots to show just how terrible the battery life is.

On top of that, the phone overheats like crazy—not while gaming (I don't even game on my phone), but while doing everyday tasks like browsing, social media, YouTube, or even listening to music. The only time it stays cool is when I’m not using it at all. I’ve attached screenshots from Thermal Guardian showing just how bad the overheating is.

What’s confusing is that I’ve seen other S25 users reporting great battery life, which makes me wonder—do I have a defective unit? Is there a way to check if my battery is faulty?

If you’re using the S25, how has your battery life been? What’s your average screen-on time, and does your phone overheat a lot? Would really appreciate any insights!

For 4000 mah battery
5 hours plus SOT is sufficient being heavy user

Heavy user meaning, your usage on whatsapp and youtube seems to be more, that also consumes battery.
My charging pattern is untill it reaches 20-25%, i charge in one go till 100%
I immediately remove as soon as it reaches 100. I dont keep it charging on 100% further

It cant be concluded this way, as per your usage and information you quoted above, 4000 mah will deliver this much only.
