For those of you worrying about battery health on your new 11pro/ 11pro max iPhones. Although battery degradation is completely normal, the degradation in going to be worse on these phones do to the fact that we are constantly using a higher watt fast charger. Not only is your phone going through a charging cycle more often, but these chargers create more heat which leads to battery quicker degradation of the battery. My iPhone 11 Pro is only 1.5 months old and the battery health is at 94%. My iPhone 10, which I purchased at the same exact time has a battery health is still at 100%. I use one as my work phone and one as my personal phone, and I almost ALWAYS charge them at the same time for the same amount of time. The only difference is that I use the 18w charger for my 11pro and the 5w charger for my 10. I hope this helps.
I thought that regardless of that charger was used that the phone ‘throttled’ the charging power to 7.5W. I use an Anker 18W power brick for my pro max and have had no problems at all. 100% after 2.5 months. No heating up while charging either.
Battery issues don’t bother me. My last iPhone, mid life had got a new battery. So what, it’s a tool, use it and maintain it like you would your vehicle. Not every battery is made exactly the same either.
