Battery health degraded When the capacity of your iPhone battery dips below 80%, you'll see the following message: “Your battery's health is significantly degraded. An Apple Authorized Service Provider can replace the battery to restore full performance and capacity. More about service options…"
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.
If your iPhone's battery health is less than 80% and you're getting lower screen-on-time, it's probably the best time to replace the battery. If you're noticing frequent app crashes or frame drops, the battery could be at fault, and it's best to change it.
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.
At What Battery Health Percentage Should I Replace My iPhone Battery? Your iPhone should retain up to 80 percent of its original battery capacity after 500 complete charge cycles. Once the battery health percentage drops below 80 percent, the amount of charge your battery can hold starts to diminish.

There is no reason to be afraid. Batteries are generally recommended to be replaced when they are below 80% of capacity, but failure isn't likely imminent. according to apple 85% is a warning, but if your phone is working fine then you can still continue using it but its better you replaced it ASAP.
An iPhone lithium-ion battery typically holds up to 500 charge cycles, or about two years; before you will see a degrading of the battery to 80% of its full capacity. You complete one charge cycle when you have used an amount equals 100% of your battery's capacity.
If, for example, 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.
Apple recommends, as do many others, that you try to keep an iPhone battery between 30 and 80 percent charged. Topping up to 100 percent isn't optimal, although it won't necessarily damage your battery, but letting it regularly run down to 0 percent can prematurely lead to a battery's demise.

If your iPhone's battery indicator turns yellow, it's a sign that your device is using what is known as “low-power mode.” This isn't cause for alarm — it's just a way for your battery, which is in need of a recharge, to be able to hold its charge for longer.

Depending upon the length of time between when the iPhone was made and when it is activated, your battery capacity may show as slightly less than 100%. A normal battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles when operating under normal conditions.
With Android devices, you still want to keep your phone's battery at 80% and above percentage the same way you would with an iPhone.
Once it falls below 80 percent, the age of the battery is significantly degraded, which can mean losing charge faster and more charges throughout the day. An aged battery can also affect your iPhone's general performance, so it is best to consider replacing it once it falls below 80 percent.
