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.
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.
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.
We can replace your iPhone battery for a service fee. Our warranty doesn't cover batteries that wear down from normal use. Your product is eligible for a battery replacement at no additional cost if you have AppleCare+ and your product's battery holds less than 80 per cent of its original capacity.

Although it depends from phone to phone, 78% isn't bad battery health in an iPhone but it is recommended to change the battery if the battery health falls below 80%.
Most iPhones last between 4 and 7 years, however this is not guaranteed. If your iPhone is more than a few years old, it's likely starting to become outdated and clunky, and it might be time to think about upgrading to a newer model for a better user experience.
Batteries are generally recommended to be replaced when they are below 80% of capacity, but failure isn't likely imminent.
It is bad, and since the battery has reached the critical point of its life, it should be replaced as soon as possible, to avoid unpredictable behavior.
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.
It's especially important to avoid exposing your device to ambient temperatures higher than 35° C (95° F), which can permanently damage battery capacity. That is, your battery won't power your device as long on a given charge. Charging the device in high ambient temperatures can damage it further.
If the onset of your battery drain is sudden, it may be that an app updated or your phone installed a patch. The newer version could contain features that are more resource intensive, or has a bug which runs your battery dry. Check to see if any apps have updated recently.
Yes, in fact, most people do just that as it is a convenient time to charge.
Therefore, we recommend the following: Do not fully charge or fully discharge your device's battery — charge it to around 50 percent. If you store a device when its battery is fully discharged, the battery could fall into a deep discharge state, which renders it incapable of holding a charge.
What to Know. The iPhone's calibration tool (iOS 14.5 and up) runs automatically, but you can check its status in Settings > Battery > Battery Health. You can recalibrate older iPhones by draining the battery, fully charging it, and immediately restarting the phone.
