Owning expensive gadgets like an Apple watch would bring many questions to the user's mind. One might wonder if they can overcharge the Apple Watch because nobody wants to damage their Apple Watch by charging it too much.

Although Apple claims the Watch will last 18 hours on a single charge, it will probably need to return to its charging cradle for some time during the day. But can you charge your Apple Watch for a long time without any worries? Is it safe to do so?

Can you overcharge an Apple Watch?

No, you cannot overcharge the Apple Watch. No amount of charging is too much for the Apple wristwatch. You can charge the Watch anytime, and at any period you want. This is because the lithium-ion batteries used in Apple watches stop charging your Watch once it reaches 100%.

The initial charging stage for lithium batteries is a fast charge, which begins when the battery level is between 0% and 80%. A trickle charge, which charges your device more slowly to preserve your battery's health, comes in after your battery reaches 80%. And lastly, once it gets to 100%, charging stops completely.

How does the overcharge feature work?

The function occasionally prevents your Watch from charging past 80%. It will stay between 75% and 80% charged; it only turns on when your Watch anticipates that it will be plugged in for a long time, such as when you usually leave it charging overnight and go to bed.

The Watch will maintain its 100% charge once fully charged by consuming trickle power from the plugged charger until you unplug it. Then, it starts taking power from the battery of the Watch. This is the reason why leaving your Apple Watch to charge overnight is acceptable. This feature is on by default. You may disable it by opening the Settings app on your Watch, selecting Battery, Battery Health, and then Battery Charging.

Do Apple Watches Come with a charger?
No, the Apple Watch does not come with a complete charger but with a magnetic charging cable that terminates with a USB port. The Apple Watch Magnetic Charging Cable is not just any regular USB cable

Can you charge your Apple Watch Overnight?

Apple confirms that the Apple Watch can be charged overnight. The manufacturer has included a Nightstand Mode, which transforms the charging Apple Watch into a nightstand alarm clock, but only while it is plugged into its charger. So it is safe to charge your Apple Watch overnight. On the other hand, while it is not harmful to charge your device overnight, there are some reasons why you should not do so.

If you use the Apple Watch to track your sleep, you should wear it at night rather than leave it in its charging cradle. In this situation, charging the Watch while taking a shower, binge-watching a TV show, or doing other menial tasks works best. Fortunately, Apple has increased the Series 7 model's charging efficiency, reducing the duration of 0% to 80% charge to 45 minutes. With this upgrade, overnight charging is now a choice rather than a necessity.

How do charge cycles affect Apple Watch battery health?

Your Apple Watch battery operates in cycles. One charge cycle occurs if you completely drain your phone's battery from 0 to 100. The more you put more charge cycles on the battery of your Apple Watch, the less health the battery has.

The Apple Watch comes with 1000 full charge cycles, according to Apple. The battery will require a service change once you have used up all 1000 charge cycles.

How can I preserve the battery life of my Apple watch?

If you want the battery of your Apple watch to last longer for you, then there are simple steps you can follow to make it more efficient and last longer.

Avoid too much heat

According to Apple, the Apple Watch should be stored between ambient temperatures of -4° and 113° F (-20° and 45° C) and operated in temperatures between 32° and 95° F (0° and 35° C).

The Apple Watch should not be left in a hot car or exposed to prolonged direct sunlight. This may decrease your battery life and harm your Apple watch.

Don't allow your battery to get to 0% before the next charge

Your Apple watch loses a cycle each time the battery reaches zero percent. The range of 20% to 80% is the ideal battery percentage for maintaining battery life. So, if you want to prolong the life of your battery, make sure it never drops below the 20% level.

Ensure your Software is updated

Make sure your Apple Watch software is up to date because Apple frequently releases new updates to solve little bugs and problems, some of which impact battery life.

Simply launch the Apple Watch app on your phone and navigate to My Watch> General > Software update to see whether an update is available.

Turn off or delete unwanted Apps from your phone

Apps are the primary cause of your Apple watch's battery draining quickly. Third-party apps require a lot of power to interface with your Watch to send necessary data. Hours of battery life can be saved by simply turning off useless apps.

Can you answer calls with the GPS only Apple Watch
Yes, some Apple Watches, like the Series 3 Apple Watch (GPS), can make calls when the connected iPhone is nearby. However, the Series 3 (GPS+Cellular) can make calls even when the paired iPhone is not close by.

Frequently Asked Questions about overcharging Apple Watch

Is it normal for my Apple Watch to be hot when charging?

Yes. Apple has confirmed that some level of heat while charging is absolutely normal. The heat is caused by the working parts of the internal components in the Watch. If the heat becomes abnormal, take the Watch to a technician to check it out.

Can an Apple Watch be charged on a charging station?

There should be no problem charging the wearable as long as the charging station is compatible with the Apple Watch. There are numerous charging docks available that work with the Apple Watch.

How can I turn on Apple Watch's Nightstand Mode?

Go to your Watch's Settings app and choose General > Nightstand Mode.


Your battery health is the major factor influencing how long your Apple watch will last. Over time, your battery health will deteriorate naturally, but how well you care for your Apple watch will impact how quickly that happens and how long your Watch will last.
