At What Percentage Should I Charge My Apple Watch? (Pro Guide)

This guide is for Apple Watch owners who want to know at what percentage they should charge their watches.

Apple Watch is a high-end smartwatch that, with proper care, can last for many years. The battery is a part of the Apple Watch that ages more quickly than other parts.

If you don’t take good care of it, it might die, and you’ll have to replace it eventually. What if I told you that there are techniques you can use to maintain the battery in your Apple Watch in good condition for a long time? Thrilled, yes? If you’re curious, continue reading because I’ll tell you more 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.

The Apple Watch uses what kind of battery?

As it will reveal a lot about the Apple Watch’s battery life and other characteristics, let’s start by talking about the type of battery it uses. Apple Watch uses a lithium-ion battery, which is arguably one of the most effective battery technologies currently on the market, just like the majority of smartwatches.

The problem with lithium-ion batteries is that they age chemically with each charge, which results in a reduction in their holding capacity.

Your battery’s capacity to hold a charge will decline as you charge it more frequently, and once it has fallen to its lowest level, it will begin to age. Low frame rates, app launch delays, screen dimming, and short battery life are a few of the typical issues you’ll encounter.

What percentage of a charge should I give my Apple Watch?

All lithium-ion batteries age, it is a fact, but there are two things that are very important in figuring out how healthy your battery is.

I’ll go over these elements in more detail in the following sentences, and you’ll also learn the solution to our main query: At what percentage should you charge your Apple Watch?

These two factors are:

  • Charge Cycles
  • The environment in which you store your Apple Watch and its battery level

Charge Cycles

Let’s begin with the Charge Cycle, which is the first factor. Simply put, a charge cycle is when your battery goes from 100% to 0% of capacity; this is regarded as one charge cycle. The battery life of your lithium-ion battery will get shorter as more charge cycles are completed.

However, the lithium-ion battery responds to various parts of the charge cycle very differently. For instance, because the temperature rises in the second segment, a battery discharge from 80% to 30% will be less demanding on the battery than one from 50% to 0%.

In my research, I came across some intriguing findings made by Battery University regarding the best lithium-ion battery charge cycle. The researchers came to the conclusion that the ideal charge cycle for lithium-ion batteries is 75% to 25% if you want to increase their lifespan by looking at how the batteries behaved at different battery levels and when they were being discharged.

It means that if you want to keep your battery’s capacity, it’s crucial to charge it to 75% and to avoid letting it discharge below 25%. Additionally, they discovered that the charge cycle between 100% and 25% was less efficient than the charge cycle mentioned above.

The best charge cycle, which they also discovered, was 75% to 65%, but the researchers came to the conclusion that this wasn’t a sustainable charge cycle.

Simply put, you must keep the charge cycle of your Apple Watch between 75% and 25% if you want to preserve its current capacity.

The temperature in which you should store your Apple Watch, along with the battery percentage.

The temperature of the surrounding air is the second factor that has an impact on the battery’s health. Apple claims that the temperature of the Apple Watch should not fall below 32°F or rise above 95°F. Apple Watch works best in temperatures between 32 and 95 degrees Fahrenheit.

The health of your battery life will be impacted if you use your Apple Watch outside of the recommended ambient temperatures, and you’ll notice a sharp decline in its health over time.

How Can I Maintain The Apple Watch Battery For A Long Time?

It’s crucial that you abide by these two suggestions if you want to prolong the battery life and overall health of your Apple Watch.

  • The first piece of advice is to avoid overcharging your Apple Watch. Always keep the charge cycle on your Apple Watch between 25% and 75% to keep the battery in good shape.
  • The second piece of advice is to avoid exposing your Apple Watch to extremely high or low temperatures. In order to preserve the battery’s health if you live in an area with extreme temperatures, try to keep your Apple Watch away from sudden temperature changes.

What Is The Best Way To Long-Term Safely Store The Apple Watch?

It’s crucial to store your Apple Watch correctly, as I’ll explain in more detail in the following sections, if you want to keep it for a long time. Apple advises that you take these four steps if you want to store your Apple Watch securely for an extended period of time.

Step 1

Making sure that your Apple Watch isn’t fully charged should be your first action is necessary. The manufacturer advises charging your battery at 50%.

If you charge your watch while it is completely discharged, it’s possible that it will enter a deep discharge state, rendering the battery useless because it won’t be able to hold a charge.

Similar to this, if you keep your battery charged to 100%, it will lose capacity over time and have a shorter lifespan. Therefore, 50% of a charge is the ideal level for storing your watch.

Step 2

In order to prevent the smartwatch from draining the battery, the second step is to turn it off.

Step 3

The third and most crucial step is to keep your smartwatch dry and in a temperature-controlled environment. Additionally, it’s crucial that you keep your smartwatch at or below 90 °F.

Step 4

Last but not least, to maintain the condition of your Apple Watch after you’ve stored it, it’s crucial to remove it every six months and recharge it to 50%.

FAQs: Frequently Asked Questions
