One week before the launch of the iPhone 12, my iPhone 11 pro battery dropped from 94% to 93%. On the day of Keynote it dropped to 92%. In the next 6 days it dropped to 91%. So every 6 days my battery drops by 1%. When I consult with friends they tell me the same information. Is it another scam on Apple to force the customer to buy a new iPhone? Yes it sounds completely absurd. But this is the same case as years ago when Apple began to slow down phone performance. From the beginning, I am extremely careful about the battery of my iPhone, I never discharge the phone below 20%, I almost never charge it to 100%. How is it possible that I have 91% after 10 months. My girlfriend has used my iphone 8 91% after two years ... How are you?
They’re is a reason the phones were slowed down, it’s widely documented. Its because without doing so the batteries would have potentially been dangerous in older devices.
And no it’s not Apple making your battery life go down, more likely how or what your using to charge it with and heavy usage.
Maybe you should try charging to 100% and letting it run down, never done me any harm and I leave mine charging all night with a 5w plug in charger.
Launch day iPhone 11 Pro on 100%
Launch day iPhone SE 2020 but used super heavily for work 98%
Launch day iPhone 11 in the same household also on 100% and no sudden health drop just as the new phone is released.
If it was programmed in, it would have occurred in September when the phones were due, not now as they should be out now.
Plus someone would have found some code to cause this and Apple would be in trouble. It does not happen.
