MarutiJhawar What do you mean? It’s all about optimization… The current battery and efficiency champion is still the Zenfone 10 even at 5.9in. Heating is easy to solve so long as there’s great software optimization (which Nothing can easily do) and all the hardware is in proper contact with a metallic inner frame. Besides, heating is an issue for 1/100 people, mostly those who do non-phone stuff on their phones…
Also, another interesting fact that I just read is that the Samsung S23 outsold S23+ by 2 to 1 worldwide showing there is a huge untapped market for smaller phones, especially for a smaller flagship which doesn’t exist other than the Pixel A series, and the Zenfone series.
