It’s feasible to lower the TDP of the i5-9300H to 15W, which could save power and extend battery life when not connected to a charger. However, reducing the TDP might affect stability, so testing is recommended before use.

You can lower the voltage and then restrict the CPU's performance in battery saver to mimic a reduced TDP. That’s the most you can achieve.

You can transform your 45 Watt i5-9300H into a minimal power CPU by setting both long and short turbo limits to 15 Watts and applying the Clamp feature. This ensures the processor stays within the 15 Watt threshold no matter the workload. Avoid using this method with Intel XTU as it doesn’t support the Clamp option. An example demonstrates a 65 Watt desktop Core i5-7600 being limited to 15 Watts, showing automatic speed adjustments. ThrottleStop displays the exact power draw of 15.0 Watts in both scenarios, confirming the throttling. Most Intel low-power 15 Watt models in the 15 Watt range employ staggered turbo limits—typically around 25 Watts for short-term spikes. You can also modify the limits to increase power when needed. Intel’s newer 10th Gen low-power U series CPUs, like the Core i7-10510U, showcase performance at 15 Watts with full turbo access.

Yes, you can transform an H-series CPU into a U-series CPU. You’ll need to adjust voltage and possibly use software tools to emulate the U-series behavior. Undervolting and limiting power draw to 15W is feasible, and you can activate this setup when the device is off. Before proceeding, ensure you have the right firmware, drivers, and possibly a compatible motherboard or BIOS update.

You're welcome. As long as the power restrictions remain disabled, adjustments are possible. Most 8th and 9th generation laptop CPUs stay unlocked by default. Yes, you can. Undervolting and power caps are managed individually. Currently, you'll need to manually configure them. If this works well for you, you might eventually be able to adjust power limits per profile. This would let them adapt automatically when switching to battery. Give it a shot and check how it performs.
