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.
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.
If you have a valid Apple Care+ plan for your Apple Watch, you’ll get a free replacement if the percentage drops below eighty.
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.
That is everything you need to know about the battery health of your Apple Watch. If you have any further questions, look at the FAQ section below.
FAQs on Apple Watch Battery Health
This feature is only available on watchOS 7 and above. Make sure you have updated your Apple Watch to the latest operating system.
Apple claims to use a dynamic system to maintain a good balance of performance and battery life with every software update. Hence, you may notice a drop in the performance.
It may cost you approximately $99 to replace the battery on your Apple Watch. For the exact price, contact Apple’s customer support.
It Is Normal for Batteries to Degrade
Under the pretext of conserving battery health and striving to keep it at the coveted 100%, do not lose out on what your device offers. Use all the best features that your Apple Watch comes with, and charge it when you need to – there’s not a lot of control you have over the battery science. Batteries are meant to age and will degrade no matter what!
