I agree - I've heard from others that the Snapdragon 8 G1 is quite power hungry and not very power efficient, especially for a SoC that was hyped by Qualcomm when it came out.

The battery life on my Find X5 Pro I believe to be linked to age. My dad owned this phone before I did so it had about a year or 2 of use which could have degraded the battery over time.

It seems that (no matter how hard people try) Microsoft will always stop supporting some CPUs for no reason. It's utterly pathetic, don't get me wrong, but it wont stop people from installing Windows 11 on "unsupported" hardware.
