I’ve turned it off in my battery testing. I Did Not Like AOD Off. I don’t care if it saves battery life. I get all day battery life already. I only use theater mode at the theater, when that was still a thing, and while sleeping. If I didn’t want AOD I could’ve saved money and bought an S4.
But again let me say this S5 is not the only Watch I’ve worn. It’s the third. And in case you’re wondering I didn’t try either of them at an Store. A friend let me try her S3 when she won an S4 from her job. The second was my Mom’s S5 Black titanium edition. She got it at launch. I got the space gray aluminum in January. But this is all irrelevant because I don’t need to have worn one to know how they work. Watches are everywhere. And I’ve had plenty of people in my life who have had them for years. You can only see the time when the watch detects movement or when it’s touched.
No, I don’t have burn in. I switch watch faces all the time depending on what band and Rhinoshield case/rim I’m wearing. I match my watch to my outfits, mood, and wallpaper on my iPhone, iPad, and iMac.
