Hello everyone! I've noticed my XPS 15 9510 is draining the battery quickly, even with the larger battery this model supports. I can't get more than three hours away from the power source, no matter what I do. I know the OLED 4K screen uses more power than a standard panel, but that's not enough to explain the issue. For instance, when I put it to sleep and closed it for 20 minutes, it only lost about 10% battery—unexpected, especially since I have to shut it down every time I carry it in my backpack. It seems to overheat and drain the battery faster than expected. Although the Dell app says the battery health is excellent, hwinfo64 shows a significant degradation (around 25%). This shouldn't be normal after a year of use. I didn't reinstall Windows upon purchase, but I did disable any unnecessary startup processes. Any advice would be greatly appreciated!

I checked the details carefully. The modern standby feature isn’t available in your current firmware version. You might need to update your system or use a different power management setting.

I would switch every sleep feature to hibernate mode.

I've tried it, but Hibernate isn't actually a substitute for S3 sleep.

It's not happening, though I've kept my laptop safe from burning itself out over the years.
