Preface
The first time to upgrade the iPhone15promax to IOS17.4,At first, I didn't find anything wrong,Then I gradually found that the phone was heating up when charging,It's the same when using a large App,Finally, I waited for the Iis17.4.1 official version update,Without hesitation,Directly plan to flash the DFU mode。
Who knows that there is no 17.4.1 firmware now, so there is only one flat brush, and then upgrade to IOS17.4.1, don't talk about the flashing process, but there is one thing that needs to be explained, for heating and battery life is not normal, DFU mode flashing can best solve the problem, in addition, iPhone15promax is very simple to enter DFU mode, which is too simple compared to the previous way.
Skip the intermediate activation setup process here, and directly test the two areas that I care about the most, which are battery life and heat control.
1. Heat control
First test charging, when charging, the mobile phone power is 36%, charged to 80%, it took 27 minutes, the problem of mobile phone heating seems to be solved, the process has been warm, there is no previous heating situation.
Secondly, test and play the glory of the king,BeforeIOS17.4,Half an hour after the game,The phone began to heat,The temperature is about 36°C,The most serious location of the heat is not in the camera,But the left sim card position,Continue the game will be more hot,The maximum temperature can reach more than 40°C,After upgrading,I still plug in to play,There is still a little bit of heating,But it's much better than Ios17.4,Because there is no temperature test instrument,So this time there is no measurement,But it obviously feels much better。
The last thing is to use Jianying to do post-editing,The heating problem has improved a little,But it's still heating,And it's more serious than playing games,Overall,IOS17.4.1Heating control is better than the previous version。
2. Endurance
After the phone is fully charged, when the test is heated to play the game, I also remember the time, test the battery life of playing the game, I played the game before, the king is about two hours, the power plummets from 100% to 30%, netizens say that there is a problem with my mobile phone, after upgrading, I played 2 rounds of peak games with full charge, it took an hour and 5 minutes, and then I also played 1 hour of peak speed, and the phone still has 56% of the battery.
This is simply too explosive,Is this power turned upside down?,It's just stunned.,Is this really a problem with the IOS version?,I summarized it.,It's probably not exactly a problem with the version.,Most of the reason should be the credit of my DFU mode flash.。
3. Signal and fluency
The signal problem is still the same, it hasn't improved, it hasn't gotten worse, and the signal is a lot better according to the setup method I shared in my last post.
The smoothness is still silky, and there are no frame drops or stuttering.
4. Auto-correct problems
This bug has been fixed.,I tested it with 11PM.,The built-in input method is normal.,There will be no more one-word input,And the problem of typos to be typed randomly。
5. New features
So far, no new features have been found, and the official update instructions are also very clear, mainly to fix the vulnerability, and it is recommended that users update and install them.
【Conclusion】In order to test IOS17.4.1, it's almost early in the morning, in general, I didn't wait in vain, the problems encountered in IIS17.4 have been solved, and I will continue to test when I go to bed tomorrow, and I will explain to you when the time comes!
