Is 84% battery health good or bad iPhone? ›

Apple considers any iPhone with a battery capacity of 80% or above to be in optimal condition. In fact, Apple feels so strongly about battery health that its 1-year warranty covers any battery at 80% capacity or more. It's not unusual to see iPhones that, after one year, still have a battery capacity of 95% or above.

Battery Health normally declines an average of about 1% a month over longer periods. So, it would normal to expect that your Battery Health would be about 88-90% after 12 months ( 1 year). Your battery is doing better than average, so nothing to be concerned about here.

100% is factory-fresh, and iPhones can run extremely well with batteries as low as 80% performance in Maximum Capacity. If your iPhone's battery health has slipped to 75% or below, it will still perform well. However, you can expect further degradation and may see lower numbers and worse performance in the near future.

Apple generally will not replace the battery unless it is down to 80%, but if you have an authorized Apple service shop nearby, you could ask them about replacing now.

How good is 84% maximum battery capacity for a 2 3/4-year-old iPhone XR? All in all, not terrible. Apple recommends replacing the battery when it reaches 80% max capacity. Replacing it isn't terribly difficult, but do have a professional do it - you don't want to break the phone in the process.

iPhone battery's maximum capacity

If the number you see under Maximum Capacity is more than 80%, you have a healthy battery, according to Apple.

Two years and at 85%…. that's about normal. The battery in smartphones are good for 3–500 cycles (about 2–3 years ) of normal usage before the battery drops below 80% and may need to be replaced if you want the phone to preform like new.

On average any iPhone will lose about 1% of capacity per month, so after 8 months the average user will see 92%. If you see 98% your phone is doing much better than the average user's phone.

As lithium-ion batteries chemically age, the amount of charge they can hold diminishes, resulting in shorter amounts of time before a device needs to be recharged. Apple won't replace the battery until it reaches 80% capacity. It takes approximately 2 years to go from 100% to 80% capacity.

So, for example, if your maximum capacity is 75%, that indicates that a full charge now will last you as long as a new battery charged to 75% would. So, if the new battery would last you for 8 hours, a battery with 75% capacity will last you for around 6 hours.

How low can Apple battery health go? ›

You can see the battery capacity maximum percentage if you go to Settings>Battery>Battery Health> Maximum Capacity. If it's less than 80%, you need a new battery.
