battery changed, but still discharging too quick

Two years ago, I bought a Samsung S23 Ultra, and its battery used to last more than a full day—over 30 hours on a single charge. But for the past 2–3 months, it barely lasts 10 hours. Once it drops to 10%, it drains completely within seconds.

I thought the issue was the battery, so I went to an official Samsung service center and had the original battery replaced. Unfortunately, the problem remains the same—the phone lasts only 10–12 hours at most. I keep my phone updated regularly, and I’ve disabled some of the AI features, but battery life is still very poor.

If this is some kind of strategy by Samsung to push us toward buying the S25, then after 10 years with Samsung, I’ll be switching back to iPhone.

Updates intentionally slowing phones down and draining battery has never been a real thing except for apple. So it's not that. Fun fact apple actually got sued for doing it a while ago. Yes newer android versions might use more power as they have more features, but it wouldn't cause such a significant drop.

Download good guardians and try battery tracker. Should show exactly what's going on. My guess is you have some app thats doing it.

And for ai, samsung ai only runs when you tell it to. So it doesn't use power. Plus most of it is processed on servers not on your device.

You could try a full device reset. It'll either be an app you have or a setting that's doing it. Kinda hard to pinpoint troubleshooting when you talked more about an update conspiracy than symptoms and things we can use to help you.
