I have already clearly described the reasons for this phenomenon - the IT industry is at an impasse. Performance growth (especially for Intel) is achieved solely by increasing SoC consumption. Even AMD is bad in this regard. While TSMC is promise 40-60% more power efficiency for the next level of tech-processes, we are seeing the opposite in the IT sector, which clearly shows reality, not virtual promises.
Back in the day, laptops started at 25-35W TDP, and this TDP was clearly supported fully and on battery, for example, in my old Thinkpad. Now the TDP can exceed 65W in PL2 even in the "15W" series, and the number of battery cells has been halved! This means that batteries can no longer deliver such a powerful current as before, when the norm was from 6 cells to 9. Where can you get a powerful current if there are 3-4 cells at best? Hence the squalor of manufacturers when switching to a battery - now laptops, due to the monstrous consumption from the PSU when battery powered, sharply lose performance for SoC and GPU, especially in boost, where the batteries are physically unable to deliver the required 65W+, or even all 100+.
This is a technological dead end. As I have written many times, there is progress in laptops when
performance grows without reducing autonomy at full speed of processors (and video cards) on battery power (especially), or even grows with new generations of SoC's. But silicon has outlived its usefulness...
