Can I Charge My Apple Watch Overnight?

The main component that determines you Apple watch’s overall longevity is your battery health. Your battery health will naturally diminish overtime, however, the way you care for your Apple watch will determine how quickly it diminishes and how long your Apple watch will stick around.

One of the major contributing factors to maintaining your battery health is the frequency & length in which you charge your Apple Watch. This brings us to the question can you charge my apple watch overnight?

Apple watches can be charged overnight and will not be in danger of being overcharged. The reason being is that Apple watches feature lithium-ion batteries which stop charging your watch once it reaches 100%.

Let’s now take a look at what actually happens when you charge your Apple Watch overnight, as well as what you will need to avoid in order to prolong the life span of your Apple watch.

What Happens When You Charge Your Apple Watch Overnight

The Apple watch uses Lithium-ion batteries which are designed to stop charging once the watch reaches a 100% of charge, meaning it will not suffer from any danger of overcharging nor will it decrease the overall health of your Apple watch’s battery.

Lithium batteries have two main charging stages, the first is a fast charge this is when your battery percentage is anywhere from 0 to 80% once your battery reaches 80% it will reach its second stage which is a trickle charge, this will charge your device at a slower pace to maintain the health of your battery. and finally, once it hits the 100% mark charging comes at a. complete halt.

So if charging your Apple Watch overnight won’t reduce or damage battery health what will?

Your Apple Watch battery works in cycles, if you burn through your phone battery from 0 to 100 that is one charge cycle, the more charge cycles your Apple watch goes through the more you are diminishing your battery health. According to Apple your Apple watch has 1000 complete charge cycles. Once you have run through your 1000 charge cycles your battery will be in need of a service change.

So how can you maintain your Apple watch charge cycles?

1. Avoid Heat

Apple states that the Apple watch works best in ambient temperatures between 32° to 95° F (0° and 35° C), and should be stored between ambient temperatures of -4° and 113° F (-20° and 45° C).

The Apple Watch is not designed to be exposed to direct sunlight for long hours nor should it be left in a hot car. All this can shorten your battery life & may even cause damage to your Apple watch.

2. Don’t Let Your Battery Go To 0%

Every time your Apple watch battery goes to 0% it loses a cycle. The optimal battery percentage for maintaining your battery life span is from 80% to 20%. So you will want to ensure your battery never goes below the 20% mark if you want to maintain its life span.

3. Store at 50%

Apple recommends that you store your device at 50% if you are considering storing them long-term. The reason being is lithium batteries become unstable when left discharged for long periods & will affect their overall battery health & life span.

How to Maximize Apple Watch Battery Life

5. Always On Display

Although a great feature the always on display feature does consume more battery life when it is turned on. Simply turning this feature of can save up to 20-30% of your daily battery life.

6. Power Saving Mode

This is an obvious one but the power-saving mode is the go-to option when looking to really save power. You can easily turn this feature on by going to the Apple Watch app on your iPhone then simply go to My Watch > Workout, and turn on Power Saving Mode.

7. Keep Bluetooth on

Disabling Bluetooth on your Phone will make it harder for your Phone & watch to communicate which in turn will cause the battery to drain much quicker.
