It limited the battery of the iPhone 15 Pro Max to a maximum of 80% charge. After a year, he looked at his current ability…

The last iPhone I had, the 14 Pro Max, I charged regularly, often 2 hours a day, but the fact is that my battery rarely dropped below 40%, I stick with it the principle throughout my life that it is better to be sooner than later and then find out that I do not have a full charge at the moment … 45-100, 55-100 etc.
After about 11 months the battery started showing me a number over 100%, the battery health started showing 99% and after about 3 more weeks it dropped to 98%.
The only thing I can say that got better is the random crashes and restarts. Even with the iPhone 11, it was common for me that when the health of the battery started to decline, the iPhone would freeze, heat up, and shut down within a few minutes. After this spontaneous crash, I always noticed a decrease in battery health. With the iPhone SE2, it often dropped at the level of 90-85% …
You could not rely on it, then it mostly started and maybe the battery was short-circuited, because after turning off the SE2 it showed 10-11% capacity, not health , but the real potential of the cost.
I had my iPhone SE2 for almost 2 years, the last one was almost a punishment. The iPhone Xr didn’t do that, it started cracking like 11ka, just when the battery started cracking. But it turned off and on and the battery stayed, only the health went down. It wasn’t until the iPhone 13 Pro Max that I had that the automatic shutdown didn’t happen. I would also personally say today that the iPhone 13 Pro Max is probably the best tuning and equipment and I shouldn’t have gone to 14k. Today I don’t have to deal with this anymore, I switched to the Pixel 8 Pro and I actually don’t have to deal with any iPhone battery health and it’s a relief. Waiting for my health to drop on my phone Christmas…
