I have been using iPhone 13 Pro Max since October 2021. All these months I have been absolutely pleased with its increased autonomy, although even at first the diabetes stress tests, using it to the maximum.
Practice has shown that the battery capacity is sufficient to put “emergency” charging out of the backpack and did not discuss that the gadget would not survive until the evening.
To the point:
▪️ I’ve been walking around for two weeks with an iPhone 13 Pro Max and trying to drain it hard. How much autonomy is enough?
▪️ Why I stopped thinking about how long my iPhone lasts on one charger
And so it was until September. I charged my iPhone only with a native charger and cable, did not turn off the “smart” power and battery management in August just one percent.
And then I installed the public release of iOS 16, and everything broke.
September minus five percent
The dark screen was taken in July, the light screen was taken on September 21st.
After installing iOS 16, I used my smartphone almost the same as before. I spent the same time on applications and instant messengers, only games have just started to be launched a little more often in order to be detected from disturbing news.
This can be seen if we compare the data on the battery:
The dark screen was taken in June, the light screen was taken on September 21. The difference in smartphone usage time is not too high.
And yet, lost the battery is not one or three, five percent, dropping to a value 94% less than in a month. This is the rate of battery wear!
The main question is: can fresh iOS 16 be to blame? It looks like yes.
We unpacked our iPhone 13 Pro Max with Nikita on the same day and use six smartphones, give or take the same. So he claims that his battery capacity dropped from 99 to 94 immediately after installing the first beta version of iOS 16.
This happened at the 94% level. I also used “betas” the first time, but in the update from iOS 15 this parameter was not affected literally until the very last moment.
But now Nikita and I were compared in numbers. The degree of wear of the original capacity of the battery is at the level of 94%.
It feels like my smartphone works without charging as much as before. In fact, apart from the numbers as a result of the battery, nothing has changed, so if you notice after installing iOS 16 you have the same sharp “negative jump» capacity The battery has been called – don’t worry.
the new iOS is a fairer difference and just shows this option correctly.
