The new iPad Pro tablets switched to the new M4 SoC and at the same time acquired OLED screens for the first time. It would seem that all this should have a good effect on autonomy, but it seems that this is not the case.
Yes, the difference is small, and the new items in the game are a little ahead, but the fact still remains. At the same time, both new tablets are more autonomous in all scenarios than the 2018 iPad Pro 11, and here the difference is often more noticeable.
It is worth saying that testing in one of the scenarios was carried out at the same brightness of 250 cd/sq.m for all four tablets, and in others — at maximum brightness, but it varies from tablet to tablet.
