Out of curiosity, what cpu? I had an i5-1135g7 laptop that I motherboard swapped with a Ryzen 7 5825U motherboard. The battery life on the i5 was atrocious. I got 2 hours out of it doing note taking. Maybe 3 when new and I had the full battery capacity to work with. After the motherboard swap, I got basically double the battery life in the same conditions.
(HP pavilion 15-eg050wm and then I put a 15-eh2085cl motherboard in it)

i5-1340P and i7-1260P
Both FW13
both get maybe 3 hours if I’m lucky. Although they are a couple years old now. Fresh battery got me maybe 4 when lucky.
I have a 25k power bank, so I can extend the runtime quite a bit. The “at least once” above is quite conservative. it’s probably closer to 2. and that includes using it while charging.
I heard the ryzens are a lot better regarding power, so it doesn’t surprise me that the runtime basically doubles

I’d recommend disabling boost and setting cooling to passive.
On windows, if you set maximum processor usage to 99% in advanced power plan settings, it will disable boost. You can set the cooling policy as well. Also repasting is probably beneficial. The more efficient your cooling system is, the less fan usage it will need and you’ll get better battery life as a result.
That’s what I noticed on the i5 laptop, it would kick on the fans doing basically nothing and would kill battery. When the fans were off, the estimates were higher. Also maybe disabling the P cores in both machines might be beneficial.

yup, I already have boosting disabled.
Mainly due to quite shoddy firmware code that controls the charging. Which causes wild battery flipping behavior even when using a powerful charger. It’s a long known issue, and FW is annoyingly quiet on the problem. It’s the reason I’m annoyed by their software issue communication handling

Ooof. Only time I had that issue was when I used a 35 watt laptop adapter with my old HP laptop. It wanted a 65 or 90 watt adapter.
