If you are an Apple Watch owner and you want to know at what percentage you should charge your Apple Watch, this guide is for you.

Apple Watch is a premium smartwatch and if you use it properly, you can use it for years. In the Apple Watch, the battery is a component that degrades faster as compared to other components.

If you don’t take proper care of it, it can go dead and you will ultimately need to replace it. But, what if I tell you there are ways you can use to keep your Apple Watch’s battery healthy for a long time? Excited, right? If you are interested, keep reading because I’m going to tell you about them.

In this WearToTrack Guide, I’ll discuss the following topics.

  • The Type of battery you get with Apple Watch
  • The right percentage to charge your Apple Watch
  • How to store the Apple Watch for the long term in the right way?
  • And many more

The secret behind keeping your Apple Watch’s battery healthy is the charge cycle and I’ll mainly focus on it because it will determine how long your battery is going to last. I’ll also share other factors which play an important role in determining the overall battery life of your Apple Watch.

So, without any further ado, let’s get started.

Which Type Of Battery Does The Apple Watch Use?

Let’s start with discussing the type of battery the Apple Watch uses because it will tell you a lot about its battery life and other attributes. Like most smartwatches, Apple Watch also uses a Lithium-ion battery, arguably one of the most efficient battery technologies available in the market.

The thing with Lithium-ion batteries is that their holding capacity decreases every time you charge them, and this whole process is known as chemically aging.

As you charge your battery more often, its ability to hold its charge will decrease, and once it’s decreased to its low, it will start showing signs of aging. Some of the common problems you will experience will be low frame rates, delays in the launch of apps, screen dimming, and low battery life.

At What Percentage Should I Charge My Apple Watch?

It’s a fact that aging happens to all Lithium-ion batteries, but there are two factors that play an important role in determining the health of your battery.

In the next few paragraphs, I’ll discuss these factors, and you will also get the answer to our main question, which is: At what percentage should you charge your Apple Watch?

These two factors are

  • Charge Cycles
  • Environmental temperature & Battery percentage at which you store your Apple Watch

Charge Cycles

Let’s start with the first factor, which is the Charge Cycle. In simple terms, Charge Cycle is when you consume your battery from 100% to 0%, and this will be considered one charge cycle. As more charge cycles are completed, the battery life of your lithium-ion battery will decrease.

However, lithium-ion battery reacts completely differently to various segments of the charge cycle. For example, if your battery discharge from 80% to 30%, it will put less strain on your battery as compared to when your battery discharge from 50% to 0% because the temperature rises in the second segment.

In my research, I came across interesting research by Battery University, where the researchers found the ideal charge cycle of lithium-ion batteries. In the study, the researchers studied the behavior of lithium-ion batteries at various battery levels and their discharging, and they concluded that the ideal charge cycle for lithium-ion batteries is 75% to 25% if you want to prolong their life.

It means that if you want to maintain the capacity of your battery, it’s important that you charge your battery to 75% and not let it discharge below 25%. In the study, they also found that the charge cycle between 100% and 25% was less effective than the above charge cycle.

They also found that the charge cycle of 75% to 65% was the best, but the researchers concluded that it wasn’t a sustainable charge cycle.

In a nutshell, if you want to maintain the current capacity of your Apple Watch’s battery, it’s important that you keep the charge cycle between 75% to 25%.

Environmental Temperature & Battery Percentage At Which You Store Your Apple Watch

The second factor which affects the battery’s health is the environmental temperature. According to Apple, Apple Watch must not be kept below 32°F and not higher than 95°F. The ideal temperature for using Apple Watch is between 32ۜ°F and 95°F.

If you use your Apple Watch outside the recommended ambient temperatures, the health of your battery life will be affected, and you will see a rapid decline in its health with time.

How To Keep The Battery Of The Apple Watch Healthy For A Long Time?

If you want to Prolong the battery life and Health of your Apple Watch, it’s important that you follow these two tips.

  1. The first tip is that you shouldn’t overcharge your Apple Watch. Always keep your Apple Watch’s charge cycle between 25% and 75% as it will help you keep your Apple Watch’s battery healthy.
  2. The second tip is that you shouldn’t expose your Apple Watch to extreme temperatures. If you live in an area with extreme temperatures, try to protect your Apple Watch from rapid temperature changes as it will affect the battery’s health.

What’s The Safe Way Of Storing The Apple Watch For The Long Term?

If you want to store your Apple Watch for the long term, it’s very important you do it the right way, and I’ll explain in the next few sections. According to Apple, if you want to safely store your Apple Watch for the long term, it’s important that you follow these four steps.

Step 1

The First step you need to do is to make sure that your Apple Watch isn’t fully charged. The company recommends that you charge your battery at 50%.

If you charge at a fully discharged level, it’s possible that your watch might go into a deep discharge state, which makes your battery useless as it won’t be able to hold a charge.

Similarly, if you store your battery at 100%, with time, the capacity of your battery will decrease, and it will reduce the battery life. So, the ideal charge level for storing your watch is 50%.

Step 2

The second step is that you turn off your smartwatch so that the watch doesn’t use the charge of the battery.

Step 3

The third and very important step is that you keep your smartwatch in a temperature-controlled and moisture-free environment. It’s also very important that you keep your smartwatch at a temperature below 90°F.

Step 4

Last but not least, once you store your Apple Watch, it’s important that you take it out every six months and recharge it back to 50% to keep it in good condition.

Frequently Asked Questions [ FAQs ]
