IPhone8P upgrade iOS 15.4 battery life upgrade is very satisfactory, and the old models can support the elderly.

Yesterday, Apple released the developer preview version of iOS 15.4beta3. This time, in addition to adding mask mode and emoticons, Apple also deeply optimized the system to make the old equipment look brand-new after upgrading. Old models such as iPhone8P upgraded iOS 15.4beta3, and shared it with you with real feedback from one day. Friends who want to upgrade can refer to it.

Continue to travel without refueling.

Because it is an old model, the battery has not been replaced, so the battery health value is 80%. After upgrading iOS 15.4beta3 for one day, you can still feel more power saving and longer battery life. When fully charged, Tik Tok 1 hour consumes power 10%, while the previous system used iOS 14.7 brush 1 hour, and Tik Tok consumes power 1 hour.

fluent

In iOS 14.7, when you double-click the Home button to call up multi-tasks, it sometimes gets stuck, and it also gets stuck when you return to the home page after running multiple programs. However, after upgrading iOS 15.4beta3, this phenomenon is much less, and most of the time the sliding switch is silky.

signal

Compared with iOS 14.7, the signal can be obviously improved. Before getting into the elevator after work, there will be no signal when there are many people, and sometimes there will be no signal after getting off the elevator for a long time. Upgrade to iOS 15.4beta3, and the signal problem will be significantly improved.

Gaming experience

In the iOS 14 system, to be honest, I dare not play games. Because I have a severe fever, I may play smoothly for more than ten minutes in front, but after running for a long time, my fever will seriously reduce the frequency and drop the frame, and the experience is very poor. After upgrading to iOS 15.4beta3, the game experience has been greatly improved, and there has been no serious fever and frame drop after long-term operation, which once again made iPhone8P the title of the strongest game console.

The above is the real feedback of iPhone8P after upgrading iOS 15.4beta3. If your system is below iOS 14, you don't need to upgrade, because the previous system is also good. If it is above iOS 14, you can recommend upgrading to iOS 15.4 to get a better experience.
