watchOS 7 adds a new Optimized Battery Charging feature to Apple Watch. We will show you how to enable it and why you should.
Reduce the Chemical Aging of Your Apple Watch Battery by Enabling the New Optimized Battery Charging Feature in watchOS 7
It's absolutely remarkable how powerful the Apple Watch is and its prowess is useful as long as the tiny battery inside it is running smoothly. Over time, that battery will give up on you. It mainly depends on your charging habits and Apple has jumped into the scene with a new feature called Optimized Battery Charging with watchOS 7.
Why You Should Enable Optimized Battery Charging
As you keep on using your devices, whether it's a phone, tablet, smartwatch or even a laptop, the battery inside it loses the capacity to hold charge. After a couple of years, the battery performance will degrade to as low as 70% of its original capacity which means your device will shut down before it hits the 0% mark or even slow down terribly.
The aging process is inevitable. But you can slow it down and that's where Optimized Battery Charging comes in. Rather than keeping your battery at full charge, your Apple Watch will learn from your charging habits and hold the charge at 80% and will only jump to 100% right before you wake up in the morning. Keep in mind that you should not (in any case) drain your battery all the way down to 0% as it hurts the battery. Same goes for keeping the battery at 100% at all times.
Batteries love to be charged frequently therefore charge them up as often as possible. The goal is to keep the battery above 50% and just under 100% at all times. Though it is recommended that anywhere between 50% and 80% is the sweet spot.
Step 1. Press the Digital Crown on your Apple Watch to go to the Home Screen.
Step 2. Select Settings.
Step 3. Scroll down and tap on Battery.
Step 4. Tap on Battery Health and then enable Optimized Battery Charging at the bottom.
You can also have a glance at your Apple Watch's remaining battery health by following the same steps above. It will give you an idea about the condition of your battery. If it's above 90% then things are looking good for you. If it's close to 80% or in the 70s territory then you might want to consider changing your charging habits a bit to keep things on hold otherwise you will experience unexpected shutdowns or poor performance.
My advice is simple: enable the optimized charging feature and always, without fail, charge your Apple Watch every single night. I've been doing it since the beginning of time and it does not hurt the battery at all. What will hurt your battery is waiting for it to drain completely, allowing it to power off and then charging it up. You really, really don't want to do that at all.
