iPhone 11 Battery Health

[Yoso]

Hello,

I have used my iphone11 for a year
with 100% battery health now it becomes
99% after a year of use is it normal to drop 1%

My 8+ was at 100% for 18 months and at two years old is at 94%. I would say you are doing well.

Another day, another battery health thread. 😂

No need to worry about battery health, it's not 100% accurate, only thing you need to do, once your battery health hits 80% get your battery changed.

Yes that sounds like a extremely healthy battery. No reason for concern.

Yes, it is an estimation after all. Don’t pay this number too much attention.

My 11 Pro Max is 1 year old and sitting at 93% Health yet the battery life is still absolutely phenomenal and lasts me 8-10hours SOT depending on usage.

I always say who cares. What is it like 50 bucks to get one changed?

To me battery health is like the first down yellow line on NFL game broadcasts. They're an indicator but not anything official. Although even if the yellow line was official the NFL would find a way to make it confusing and not easy to understand. *cough*

Like others have said, your device is fine -- and don't get concerned over the number.

As a comparison/foresight...

My 3.3 year old iPhone X's battery is at 85% health (according to iOS)
• Most instances I do a full cycle with usage (100% -> auto-shutoff, back to 100% in a single charging session).
• I use a 5 watt Apple adapter, 10 watt Apple adapter, 7.5 watt Anker Qi wireless charger + 10 watt Apple adapter, or Mac mini to charge my iPhone.
• Each (full) charge lasts about 24 to 48 hours (depending on usage, of course).
-- For example, at the moment: battery charge is at 45%, last charge to 100% yesterday at 6:56 AM.
