A:Answer Personally, I charge it at night and wear it all day and battery lasts all the journey. I don’t use many apps, but I do use the work out tracker, reproduce music with Bluetooth earplugs, and get the sms, email, fb notifications... the basics. I guess if I turned it off, it would last maybe few hours more, but for what I use it, the battery lasts perfectly with the always on. Worth it!
