Battery life suddenly became much worse on TUF A15 2023

I am using TUF A15 FA507XI. Recently laptop battery life suddenly decreased from 9 hours to 2-3 hours, and power consumption shown is 30-35W, while normally it's around 10W. Also it's constantly overheating and turning fans on while not being loaded. I am using Linux, and at first I thought it was issue with it, but when I left laptop in BIOS menu with 97% battery, it ran out in 2 hours. The last time I updated the BIOS was around 6 moths ago, so the problem is not the BIOS version. Does anyone know what can cause such problem and how it can be solved?

After some tinkering I've figured out that it was actually software issue that appeared on both my system and Live ISO I used to test it. I reinstalled my system and now it works properly.

I thought that battery life will be good enough in BIOS menu as it's basically just running idle, doing nothing. So if it ran out in 2 hours then it's hardware problem. But such a bad battery life here is normal, maybe because it's not turning on some power saving options.

Hi, are you using dedicated gpu while on battery power? If yes, switching to integrated graphics will help. Also disabling cpu turbo mode will help. Switching refresh rate to 60hz can help too. You might also check what's running in background using task manager. It'll show you if something is using a lot of resources. It's not much, but I hope it'll help you.

I'm not sure about Linux, but on Windows you can use armoury crate, or ghelper, and from there, switch to silent mode. Along with previous points I've suggested, this will keep cpu temps down and therefore fan noise
