Apple Watch 2 - OK to Top Off Battery?

[BigMac3]

I just got my first Apple Watch and it's a series 2. Love it. This is my second day with it and the battery is at 75% at 11:15 am. I'll be out late with it tonight.

The question: Will I degrade the battery if I want to top it off to 100% before I leave the house? Are small charges like that ok?

Its no different than any other Lithium-ion battery. It doesn't have a memory. You can charge it 100 times from 99 -> 100% and it will only count as one charge cycle.

Well yes and no. While doing that will only count as 1 cycle, it will reduce the max number of cycles much faster than *regular* charging.

As a general rule, lithium batteries are best kept between 20 - 80 %.

High and low state of charges actually do the most damage to the battery chemistry and electrodes.

Electric car battery manufacturers get much more than the average 1000 cycles of (high quality) consumer electronics cells by using this technique (amongst others like temperature control).
I.E when your EV says it's 100% the cells are in fact at ~80-90% max.

You really do not need to worry and you can charge often or not. Just do not run you battery down to empty. And before someone points out that can not be done, I know it is not really empty.

Just enjoy your watch and do not worry.

I am getting almost two full days battery out of my Series 2 between charging. I am amazed at the performance. I am doing my darnedest to keep the battery in healthy condition by not charging it before it is nearly dead.

What's nice about the Watch is it charges quickly. Even 15 minutes can jump the Watch up close to 20% if you were running low.
