The most logical thing is to install a more powerful battery. Now the standard is 4000 mAh, some companies produce 6000 and even 7000 mAh batteries for mainstream phones.

Not only the amount of available energy plays an important role, but also the efficiency of its use. Almost all modern processors are manufactured in 8nm process technology. Usually, this is done by TSMC. So, their factories produce chips of companies Huawei, Qualcomm, partially Samsung and even Apple...
