Passing from the iPhone 14 Pro, whose maximum battery charge capacity was 87% after two years of use, on the iPhone 16 Pro, I was a little shocked. I realized that the iPhone 16 Pro battery could reach 87% maximum capacity much faster than my old iPhone did.
Between September 20, 2024 - November 6, 2024, at a level of use below the environment, and with only 35 loading cycles, the maximum load capacity decreased to 90%. At that time, I said it was because of a wrong calibration, because I found this rapid iPhone 16 Pro's rapid health degradation.
The article is here: The iPhone 16 Pro battery is surprisingly quickly degrading. 98% maximum capacity in less than 2 months!
After 106 days of use, I come back with an update to my iPhone battery, which has now reached 70 charging clicks and 96% maximum charging capacity. In other words, after less than 4 months of use, in which during the sleep the battery passes automatically in low power mode (low mode), it has degraded considerably.

How long and how many charges will the iPhone 16 Pro (Maxim Capacity) battery reach 80%?
If I am to take the data on my device, the iPhone 16 Pro battery will reach 80% in May 2026. How did I do this calculation? Very simple, with mathematics.
Between September 20, 2024 - November 6, 2024, the capacity decreased from 100% to 98% in 35 loading cycles. That means a rate of iPhone 16 Pro battery degradation 2% after 35 of cycles, or 0,057% per cycle.
Between November 6, 2024 - January 6, 2025, the capacity decreased from 98% to 96% in 35 cycles, which means a rate of 2% in 35 cycles, or 0.057% per cycle. With percentages similar to the first period in which I made the calculation, it turns out that in 108 days, the battery degradation rate was linear.
Based on the above report, it means that 280 charging cycles will be needed to lose another 16% of the maximum battery charging capacity. This means that the iPhone 16 Pro battery will reach 80% after 350 charging cycles (May, 2026).
How long should i get the iPhone battery at 80% Maximum Capacity?
Apple claims that iPhone batteries are designed to maintain up to 80% of the maximum initial capacity after 500 complete charging cycles, under normal use conditions. This would mean not to use the phone at high temperatures, use original accessories for supply and do not abuse games and multitasking applications.
To maintain the general battery health, it is also recommended not to charge it more than 80% and not allow it to unload below 20%. In other words, being a little ironic, if you want to have a high performance iPhone of 1200 EUR and whose battery does not fall below 80% of capacity in less than 2 years, it would be ideal to enjoy 60% of the battery capacity and not use it, because it can affect it.
As for me, I can say that I am a Apple fan, if I am to take the number of devices (MacBook, Imac, iPad, Apple Watch, Airpods, etc. Accessories), but I feel that after 12 years of iPhone, the return to Android phones is approaching. I do not delight the idea, but Apple's quality-price ratio of recent years, leaves to be desired. Innovation not at all, I could even say regress in some aspects, restrictions for the EU countries, plus many other absurd limitations on devices.
