The new iPad Pro tablets switched to the new M4 SoC and now have OLED screens for the first time. It would seem that this should have a good effect on autonomy, but it does not seem to be the case.
The author of the channel Dave2D has already tested Apple's new products and it turned out that in two scenarios out of three they are inferior to the iPad Pro 12.9 on M1.
Yes, the difference is small, and in the game the novelties are quite a bit ahead, but still the fact remains. At the same time, both new tablets are more autonomous in all scenarios than the iPad Pro 11 of 2018, and here the difference is often more noticeable.
It is worth saying that the testing in one of the scenarios was carried out at the same brightness of 250 cd/sq.m for all four tablets, and in the others — at maximum brightness, and it is different for different tablets.
