Can You Overcharge Apple Watch?

Can You Overcharge Apple Watch

Apple Watch is no doubt one of the best smartwatches available on the market, but its major drawback is its battery life. You just cannot wear it for two straight days without charging. And the problem starts when you cannot find the right time to charge your Apple Watch. You cannot charge it during the day because you are probably out of your home and on your feet all day, and you want to track all the physical activities that you do the whole day. You must also want to measure your sleep to keep track of the rest that you are giving to your body, right?

Therefore the only solution that is left is to charge it when you are having leisure time in the evening. But I know it must have happened many a time that you forget to unplug your smartwatch from charging. And now you are wondering if it is getting overcharged and doing any harm to your Apple Watch.

So let me put your wonderings to rest. Do not worry, you cannot overcharge your Apple Watch.

Apple Watches have lithium-ion batteries that get charged in three phases. Let us look at three phases briefly to understand why Apple Watches do not get overcharged.

1) Fast Charging Phase

The first phase of charging is the fast charging phase. In this phase, the battery gets charged at a rapid pace from 0% to 80%. Apple Watch Series 7 takes just 45 minutes to get charged from 0% to 80%.

2) Trickle Charging Phase

Once the Apple Watch reaches the 80% mark then the trickle charging phase starts. In this phase, the charging pace of the smartwatch is slowed down and it takes a considerable amount of time to reach the 100% mark. For instance, according to the Apple Watch Battery article, Apple Watch Series 7 takes around 30 minutes to get charged from 80% to 100%. While, as discussed earlier, it takes just 45 minutes to reach 80% charge from 0%.

3) End Phase

Once the Apple Watch battery is fully charged, the third phase of the charging starts. This phase stops the smartwatch from getting overcharged. As long as the battery is fully charged, it will not further charge the battery. And that is why you do not need to worry about overcharging your Apple Watch, be it Series 7, 6, 5, 4, 3, 2, or SE.

Is It Bad To Charge Apple Watch Overnight?

Is It Bad To Charge Apple Watch Overnight

Not many people track their sleep and therefore the best time for them to charge their Apple Watch is when they are sleeping. Because when they wake up in the morning, they find their watch to be fully charged and ready for the whole day.

But is it bad to charge your Apple Watch all night?

No, it is not bad to charge your Apple Watch overnight. As discussed earlier, Apple Watches come with lithium-ion batteries that cut off charging when fully charged.

To help you even further, Apple Watches these days come with an Optimized Battery Charging mode. This keeps track of your daily charging and learns from them to optimize charging accordingly. As a result, it maintains your Apple Watch battery health and you also get it fully charged when you need it. You can read the charge Apple Watch article to know how you should charge your Apple watch.

How To Increase The Battery Life Span Of Apple Watch?

Apple Watch Charging

There are plenty of things that you can do to increase the battery life of an Apple Watch on a single charge. But let me tell you how you can increase the battery life span of your Apple Watch so that it lasts longer without any battery replacement.

1) Avoid Extreme Weather Conditions

According to Apple, the ideal temperature zone for Apple Watches is between 16 to 22 degrees celsius. The batteries of Apple Watches are designed to perform to their fullest potential in this temperature range. But their battery capacity can get permanently damaged if you take them to an environment having a temperature of more than 35 degrees celsius. Similarly, if you take your Apple Watch to a place with extreme cold weather then you will see a decrease in its battery life.

2) Update Your Watch OS To The Latest Version

Try updating your Apple Watch to the latest Watch OS available out there. As Apple is working continuously to improve the battery life of their watches so they release new battery-saving technologies in their new operating systems. So, if you update your Apple Watch OS then chances are that your smartwatch’s battery life, as well as battery life span, will increase.

3) Remove Watch Cases While Charging

Some smartwatch cases can cause excessive heat while your Apple Watch is on charge. And as discussed earlier, a higher temperature can cause permanent damage to the Apple Watch’s battery capacity. So remove your smartwatch case while charging in case you feel your Watch is getting extremely hot.

4) Always Store The Apple Watch When It Is 50% Charged

If you are planning to not wear your Apple Watch for some time then always charge it to around 50% before storing it. Storing the smartwatch when it is fully discharged or fully charged can cause the battery to lose its capacity.

Should You Charge Your Apple Watch Overnight?

As discussed earlier, charging your Apple Watch all night long will not damage its battery but somehow I still feel that leaving your Apple Watch on charge the whole night is not an ideal thing to do.

Also, Apple Watch Series 7 comes with fast charging support and takes just 45 minutes to get charged from 0% to 80%. Leaving the smartwatch on charge for 7-8 hours, which can really be done in about an hour does not seem ideal to me.

I would in fact suggest you charge it in the morning when you are getting ready. If I am not wrong, you must take at least 45 minutes to do your daily chores, right? So why not charge it then. The additional benefit of charging your Apple Watch in the morning is that you can also track your sleep while wearing it overnight.
