Hi
I have an ASUS FX505 with an Intel i5 9300h processor. It's a 45w CPU.
Sometimes I don't need the full power and want longer battery life without a fan spinning. Right now it lasts about 7 hours on low brightness.
I tried using Intel XTU and undervolting the CPU by -0.145, but it helped only slightly.
Are there any options to reduce TDP like with Ryzen models? For example, Ryzen 4800h which can have a lower TDP of 12W?

Various Intel CPUs offer adjustable TDP, while others do not. The exact setting varies by laptop model. To save battery life, use a desktop cooler—heat increases resistance, causing the battery to draw more current to keep voltage stable, which generates additional heat. Place the laptop on a flat surface and let air circulate underneath. Laying it on your lap or using blankets traps heat, worsening the situation.

Switch the Windows power plan to Power Saver.

I'm taking things seriously. Switching to Power Saver usually forces the CPUs into their minimal power modes. You don't need to deal with XTU or anything else.

I started by setting it to power saver first.
Then I restricted the CPU to 19% and so on...
But when I saw my friend's laptop with Ryzen and those settings, I wondered if it was possible to limit TDP in a similar way on Intel as well. I couldn't find any information about that for laptops.

Even if you managed to reduce the TDP, you'd still need to match the same settings as the Power Saver option would have provided. Previously, adjusting the power plan to Power Saver kept the CPU around 1GHz, rarely exceeding it and avoiding overheating.

it doesn't function properly, especially for me... maybe you're using a U-series CPU?

The most recent Intel laptop I owned was a Dell Inspiron Gaming 7577 equipped with an i7-7700HQ. Perhaps it would be better to begin fresh and inquire about your current device.
