iPhone 11 battery life stuck at 80%

The battery maximum capacity indicator is an estimate. If yours has been stuck at 80% for two years, though, there is something wrong. I suspect that your battery is long past needing replacement.

There are people who complain that every phone has worse battery life than the phone before and that every update ruins their battery. Take that with several pounds of salt.

Referring to the "Your battery's maximum capacity" section of the support article: iPhone Battery and Performance - Apple Support

"A normal battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles when operating under normal conditions." Even rechargeable batteries get worn down and 1-2% health loss per month is perfectly normal. According to iPhone Battery and Performance - Apple Support , Apple apparently only considers it unusual (and warrant-able) if a battery drops below 80% maximum capacity in less than a year after you receive it. Ergo, some storage loss as you use it is anticipated and acceptable. Prorating that possible 20% drop over the first 12 months equates to 1-2% drop per month being within the range of what Apple finds acceptable. "The one-year warranty includes service coverage for a defective battery. If it is out of warranty, Apple offers battery service for a charge." In other words, if maximum capacity is below 80%, the battery is below normal performance and worth replacing. A notification will appear about this. You can still use a device with a lower health percentage than 80% but for optimal usage you may wish to consider having it changed when it reaches 80% battery health.

- If battery health drops a few percentage per month that is normal.

- If battery health drops below 80% before the end of the first year, contact Apple about a warranty replacement. (Apple will test it to determine its actual eligibility.)

- If battery health drops below 80% after the first year, consider getting the battery replaced but anticipate paying for it.

Battery LIFE not battery stuck at 80%

Being as cynical as I am, spending a franklin on a battery vs a new iPhone in september

I had the battery in my iPhone 11 Pro replaced last October when it was still $79 as opposed to the current $89. It was well worth it. The phone felt brand new. It essentially got me another year of use. As the phone now seems to be developing a BT issue, I plan on replacing it when the 15s come out. But, if it weren't for that, I'd probably keep it for at least another year.

Battery LIFE not battery stuck at 80%

I did focus and read exactly what the OP wrote: "The battery on my iPhone 11 has been stuck at 80% for 2 years now." And the original poster did not disagree with the interpretation. Why are you now, ten months later, criticizing the way the post was ansered?

If you have an issue of your own, I suggest you start your own thread. It sounds as if your problem may be different than the one in this thread.

A hundred bucks will get you another 2-3 years of service. Seems like a no brainer unless there is some special feature that a new phone offers that you must have.
