How to Check Apple Watch Battery Health: Everything You Need to Know

Apple adds a battery health counter to every device it makes, including the Apple Watch. While it is good to keep track of how the battery is holding up over time, most of us get worried when the health percentage drops. So, we’ll help you understand and check the battery health of your Apple Watch.

Check Apple Watch Battery Health

In this article, we want to show you where you can see the battery health percentage of your Apple Watch. Further, we’ll help you correctly understand and interpret the battery health level, when you may need to replace it, and how to maintain good battery health over a period. Let’s begin.

How to Check Battery Health on Apple Watch

Here’s how you can check the battery health of your Apple Watch.

Step 1: Press the Digital Crown once and tap on the Settings app.

Step 2: Tap on Battery.

Step 3: Select Battery Health.

Step 4: You will see the current maximum capacity of the battery.

But what does this number even mean, and what does it say about the battery – let’s find out.

Understanding the Battery Health of Your Apple Watch

The moment your new Apple Watch is out of the box, the battery health is at its peak one hundred percent. Over a period of time, the lithium-ion battery undergoes several cycles that involve charging and discharging it.

The anode and the cathode are the key components of a lithium-ion battery. During the process of charging or discharging a battery, lithium ions flow between the anode and the cathode. However, due to a few unfavorable reactions over time, mainly due to heat, the amount of available lithium ions for conduction is reduced. This results in the degradation of the battery.

Therefore, the battery health level, which is its current ‘Maximum Capacity’ on your Apple Watch, indicates this, at least as per Apple. But what is the rate of this degradation? How quickly do the numbers drop on the battery health indicator on the Apple Watch? Let’s find out!

How Quickly Does the Battery Health Decline on Apple Watch

On a normal usage basis, when you are charging your Apple Watch around once every day, you can expect the percentage to drop anywhere between 1-2 percent every month. Apple says that over two years, it is normal for battery health to drop by 20 percent.

For reference, we’ve been using our Apple Watch for over a year, and the battery health currently stands at 96%. There isn’t a defined rate at which the battery health meter decreases. It is purely an estimate and isn’t a measurement that directly correlates to physical changes in your battery.

However, if the battery health drops by around five percent or more in a month, you should contact Apple’s customer support, and they’ll help you diagnose if there’s any issue with the battery.

What Is the Lifespan of the Battery on an Apple Watch

The battery on your Apple Watch is expected to perform well and last around 2-3 years. When the battery health percentage drops below 80 percent, you should replace it for the best possible performance.

There’s no need to worry as long as you don’t notice a significant change in the battery performance on a daily basis. Sure, over time, you will see a decrease in the battery performance, but as mentioned earlier, it is normal. As long as you get at least a day’s worth of battery life on your Apple Watch, you do not have to be concerned about the battery health level.

However, you can follow a few habits to maintain good battery health on your Apple Watch. Here’s what you need to know.

Tips to Maintain Battery Health on Apple Watch

Here are a few key aspects you need to consider to take good care of the battery’s health and lifespan on your Apple Watch.

1. Use the Original Charging Accessories

We highly recommend using the original charging accessories for your Apple Watch. If you want to use a third-party accessory, ensure they’re MFi-certified. These accessories are certified to charge your Apple Watch safely, and the components present will not produce excessive heat, thus protecting the battery’s health.

2. Enable Optimized Battery Charging

When you enable Optimized Battery Charging, your Apple Watch learns from your daily charging routines. It observes when you usually charge your watch and how long it stays plugged in. Based on this learning, the feature helps slow the battery’s aging process.

Here’s how you can enable it on your Apple Watch.

Step 1: Open the Settings app.

Step 2: Tap on Battery.

Step 3: Tap on Battery Health.

Step 4: Turn on the toggle for ‘Optimized Battery Charging’.

The feature aims to de­crease the amount of time­ your Apple Watch remains fully charged. If you usually charge it overnight, this feature can de­lay the charging of the battery to 100 percent until right before you wake up. The intention behind this is to maintain your battery at an optimal level, preventing instances where it stays fully charged for an extended period. Such situations may contribute to battery aging.

3. Avoid Fully Discharging the Battery

It is recommended to avoid completely draining your Apple Watch battery because lithium-ion batteries have a limited number of charge cycle­s before their capacity begins to decrease.

Fre­quently discharging to zero and recharging can use­ up these cycles faste­r, resulting in premature wear and reduced battery life­ over time. Therefore, keeping it within a moderate range, such as 20-80%, is generally recommended.

4. Update Your Apple Watch

Software updates on your Apple Watch implement various algorithms that help the battery keep up with the ever-increasing power demands of apps and services. Further, if Apple notices any software bugs draining the battery unnecessarily and contributing to battery aging, these bugs will be removed by the software update.

Here’s how to update your Apple Watch. 

Step 1: Open the Watch app on the paired iPhone.

Step 2: Tap on General.

Step 3: Tap on Software Update.

Step 4: Download and install a new update, if available.

Your Apple Watch must have at least 50% of battery level and be charging as you install the update.
