You have been with your iPhone for a while and you start to realize that the battery is no longer what it was. For people with a busy schedule, this is even more obvious. In the first few days, you may come back from a long day with 40% battery remaining. Now the device only has 20%; finally, a few months later, you run to the charger as soon as you enter the apartment.

While there are some steps you can take to conserve your battery, it will continue to drain over time. This means that you will inevitably have to replace the battery if you don’t want to buy a new device right away. Given how good Apple’s support is for older devices, it makes sense to breathe new life into your device in this way.

But before we help you decide when to replace the battery, let’s first review some readings that we’ll interpret later.

You only need one for this tutorial. iPhone with iOS 11.3 or later.

It’s simple: you’ve probably already come across this feature. To determine the battery level percentage, go to Settings > Battery > Battery level.

The metric we are looking for is this Maximum capacity in percentage. You can use this number to get an overview of the battery status. Please note, however, that this number is highly abstract and does not necessarily reflect the actual condition of the battery.

This number is especially useful for situations with bad batteries. In the case of defective batteries, the value decreases rapidly over the course of a year. That’s the same time Apple offers free replacement batteries.

If you’re reading this article and you’ve only had your device for a year, that’s a bad first sign. If you just checked that number and it’s below 80%, you need to hurry up and have Apple replace the battery before your warranty expires.

Another point to consider is the maximum throughput capacity. This indicator shows the status of the power management system. Over time, Apple will throttle the performance of older devices in favor of longer battery life. If the following message indicates that the battery is normal, that means your device is working as it should and the battery can provide enough power to all systems. However, if you see anything else, it means Apple is throttling your iPhone’s performance to conserve battery power.

You can disable this “limiter” by tapping the “Disable” button on the notification. Please note that you will only be able to reactivate the function if the battery no longer provides the necessary power.

What does the battery status indicator say?

Well, unless you’re an Apple engineer, you probably mean the same thing I do. Apple itself claims that the number is tied to the number of full charge cycles the battery has had. With 500 full charge cycles (the number of times the battery has been discharged to zero and then recharged), the battery should be able to retain approximately 80% of its original charge.

However, the percentage of battery health should be taken with a grain of salt. There are a number of reasons that make it an “irrelevant” condition indicator. First of all, the percentage shown is an approximation. No two lithium ion batteries can be exactly the same. Also, the mAh number listed in the datasheet is also just an approximation. Therefore, as a general rule, the actual mAh number at the time of purchase may be higher or slightly lower.

Therefore, your device may still show a high percentage of performance, while the actual experience with the device is much worse.

When should you replace your iPhone battery?

A more recent metric to check is the battery level graph in Settings. You can find this graph below. Settings > Battery. This graph shows the actual percentage throughout the day. You can also check a 10-day chart by tapping the “Last 10 Days” button.

Then you can take a look at the activity graph below and you will see that there is logically a direct correlation between battery depletion and usage. The more you use the device, the more power it will consume and the faster the battery will drain. If you see this graph dropping too quickly, that’s a good indicator that you need to replace the battery.

Another factor is the actual battery percentage. This should be pretty predictable from day to day. At 40%, you should generally be able to spend the same number of hours each day. However, if this screen frequently freezes, shows the same number for longer than necessary, and then drops sharply, this is a sign that the battery is slowly draining. There are ways to make this display more accurate, and the linked article tells you how.

The key factor is your personal experience. A battery that drains 20% faster might be fine for someone who has constant access to an outlet. However, for someone who is constantly on the go, it can be a problem. No one wants their device to turn off while they’re still outside, especially when they’re away for work. Therefore, if you are no longer comfortable with the battery life of your device, you should consider upgrading or replacing the battery.
