Recently, the IOS15.4, which lasted more than a month of internal testing, was finally released, and the arrival of the much-anticipated wearing mask unlock function is very practical for us in the epidemic period, solving the pain points of many iPhone users' daily use.
However, some users have reported poor battery life after the OTA upgrade, the iPhone 11 consumes 80% of the power in 24 hours, while the screen on time is only 2 hours, and the iPhone 13 Pro Max can only last half a day.
Some professionals claim that every time the iPhone updates the system, it triggers a lot of things in the background, from indexing to recalibrating the battery, which can last for hours or even days, which gives the impression of faster power consumption.
There are also some users who speculate that Apple has started to use the proMotion refresh rate of up to 120Hz more frequently, but this is not the case, because only the iPhone 13 Pro and Pro Max currently have a ProMotion refresh rate.
Apple officials said that it has been investigated for the battery life crash problem raised by some users, and as for the final situation, it will be solved in the future, and it seems that Apple is likely to solve these problems in the next version.
