It is fair to say that the battery in Apple’s iPhones is a bit of a mystery box. Unlike some of its rivals, it’s not detachable, so you have to trust that what you’re receiving is decent. A solid battery is just as crucial as a sleek design when opting for a refurbished iPhone. For example, if you decide to get a refurbished iPhone 12, you need to first check the phone’s battery life before clicking the “buy” button. 

We will answer some frequently asked questions about iPhone batteries in this article, from understanding good capacity levels to the average performance of an iPhone battery across different models. We will also explain what to do if your iPhone X battery life decreases to 88%. 

Knowing Your iPhone’s Battery Capacity

With the introduction of iOS 11.3 in 2018, Apple added a new feature called Battery Health, which may tell you a lot about the capacity and operation of your battery. It specifies how long your iPhone should survive between charge cycles on a scale of 0% to 100%.

The maximum battery capacity of your phone degrades with time. New iPhones usually have a capacity of 100%; however, charge cycles and potential damage (such as exposing your phone to severe temperatures) lower capacity.

As the health of your battery deteriorates, so does its capacity to give peak performance.

What is the iPhone Battery Capacity Optimal Condition?

You could believe that the only situation that qualifies as ideal is when your iPhone’s maximum capacity is at 100%. That’s not exactly accurate, though. Any iPhone that has a battery capacity of 80% or higher is deemed to be in excellent condition by Apple.

Apple cares so much about battery health that any battery with 80% or greater capacity is covered by its one-year warranty. It’s common to find iPhones with a battery capacity of 95% or higher after a year.

Because Apple manufactures its batteries with surplus capacity, even when the Battery Health indicator reads 100%, it doesn’t use all its available operational power. Your phone is still functioning at its best, even at 80%.

How to Check Your iPhone’s Battery Status

You can check your battery capacity on any iPhone running iOS 11.3 or later by navigating to Settings > Battery > Battery Health. It’s vital to remember that this function is only accessible on iPhone 6 and later devices.

You’ll also notice a significant additional measure called Peak Performance Capability on your Battery Health panel. This screen may be more crucial than capacity due to the subtlety.

You will receive a notice stating that your phone performs at normal peak levels if your battery runs optimally to support all your apps. You will notice a notification that your battery has worsened and needs to be changed if it is worn out and may need repair.

Your phone will still work if you see the warning message, but the distance between charges will be considerably shorter. The notice shows only when your battery level is 79% or below.

If Your iPhone X Battery Life is 88%, What Should You Do? 

The battery is in excellent condition 88% of the time since its capacity is only 12% lower than when it was new, at 88%. That implies that if your battery lasted 10 hours when it was new, it would now last slightly under 9 hours. If this is a severe problem for you, get a new battery. However, you do not require a new battery. Nonetheless, if the health goes below 80% or you see a power drain, you should consider changing the battery. Unless you feel the battery life is insufficient for your purposes, changing the battery may be a wise option. However, it is still not recommended.

You can keep using your iPhone X with the present battery until you realize that it has to be charged more frequently than you would like. The proportion of battery capacity is essentially unimportant. Replace the battery.

How to Increase the Battery Life and Performance of Your iPhone

Apple has attempted to increase the battery life of their phones using a process known as performance throttling, or performance management, which sparked some debate a few years ago. Performance management throttles your phone’s performance on your behalf to keep the iPhone functioning and save battery power. You may turn it off manually, but your iPhone’s battery will drain rapidly since the iPhone will be working near its limitations.

Instead, follow a few simple steps from Apple to improve the life of your phone’s battery:

• Maintain the most recent iOS update. Every major release brings additional features for preserving and extending battery life.
• Keep your phone in average temperatures ranging from 16 to 22 degrees Celsius. Anything above and beyond this may be harmful to your lithium battery.
• When charging, avoid generating too much heat. Some cases or surfaces might cause your phone to overheat, resulting in battery damage. Check it while it is charging to ensure that it remains cool.
• Keep your phone partially charged. Emptying the battery fully may lead it to enter the deep discharge, resulting in substantial damage.
• The drain from a fully charged battery may have the same effect.
• Enable auto-brightness. The brightest screen settings drain your battery, forcing you to cycle through charge cycles quickly and lose battery health.
• In Settings > General > Background Refresh, look at your background activities. Running too many programs in the background may deplete your battery.

Final Thoughts 

The battery is in excellent condition 88% of the time and does not need to be replaced. If the battery’s health goes below 80%, you should consider replacing it. Unless you feel the battery life is insufficient for your purposes, it may be a good idea to replace the battery. It is, however, still not recommended. However, if you are planning to buy a refurbished phone, for example, a refurbished iPhone 12, it is crucial to check the iPhone’s battery life with the seller.
