As stated above, this thing has frozen about 600 times in the last week. It only started this after updating to IOS17. it also won’t hold as much of a charge. Even dropped from 100% battery health to 96%. I literally just bought the phone and had the battery replaced in June. This is pathetic.
A lot of people, especially Apple fans and so-called mainstream tech reviewers, often do not criticize Apple or point out its flaws. The iPhone is notorious for having poor thermal cooling capabilities, the CPU often gets hot according to thermal tests. Apple doesn’t want to put a copper heatsink or other thermal cooling hardware inside their iPhones. The hot CPU can cause the battery health to degrade sooner. Some Android phones have very good cooling systems, usually a copper heat pipe, a copper vapor chamber, or thermal pads. Another problem is Apple pushing their MagSafe wireless charger, but wireless charging is known to create extreme amounts of heat which significantly lowers the battery health within a short period of time. And also, Apple was so stubborn, they kept using the Apple lightning connector all the way to the iPhone 14 until the EU forced them to switch to USB C on the iPhone 15 and beyond. The Lightning connector is not very efficient and gets hot, especially when fast charging. So there are other ways the iPhone can get exposed to extreme heat which is not good for the battery health in the long run.
I suspect that Apple may purposely decrease the battery health number after a software update, probably to make people think that their battery health is lower than it actually is. This is because I also saw my battery health drop from 95% to 88% pretty quickly after a software update which was strange.
