Guys fistly godo to be here. I'm a long time occasional Apple user (testing software on iPhone 4S through to 6S) who has recently decided to give up on Windows Phone and Android and go full Apple. Recent purchases include iPhone X, Air Pods, Ipad Pro (with smart keyboard), Apple TV 4K and finally a Pencil. Historically for a wearable I've used a Microsoft Band, then migrated to a Samsung Gear S3, and lastly (and currently) a Fitbit Ionic. The Gear S3 I loved and used it with a Galaxy Note 8 (still owned), but with Samsung reducing support for flagship devices to around 2 years I decided to go the whole hog with Apple. High prices but butter support. So that is the background. I'm a 55 year old male, techno addict, and IT manager, looking to improve my fitness levels (hence the Ionic) and as I've gone Apple I'm considering going for a Series 4 AW when (if) it launches in September (or failing that a S3 LTE model). My concerns / questions are: Battery Life - The Ionic can last days on a single charge but my working regimen is to put a the watch on charge each morning for 35 minutes (shower time) and if that gets me fully charged and through a day I'm happy. Can similar be achieved with an AW or would additional charging be needed? Night time - I need to wear the watch at night to see the time, due to poor eyesight bedside mode would not work for me, and I guess the plan is to put it into Theatre mode at night. Question, is that was done what battery charge loss would be experienced overnight? Heart Rate detection - I'm heavily tattooed (black & red) on my left arm and the S3 could never read my pulse through the ink. The Ionic has no such problems and tracks with no issues. Am I likely to experience any difficulties with the AW? Apple Pay - when a purchase is made via the watch do you get an electronic receipt or notification on the iPhone? Bar Code App - I frequent Costa Coffee in the UK (similar to Starbucks) and on the Ionic I use a Barcode application which allows me to present my Club Card QR code to claim rewards points. Is a similar app available for the AW that could be used to present the code? Can the AW be charged using a regular (phone) QI charger? If a 2FA Authenticator request is triggered by the Microsoft Authenticator App on the iPhone can the watch see the request and respond to authenticate it? I'm a big fan of the Audible audio book system, can the AW be used to pause / playback of the audio of an audio book? Similar to the above can the AW pause / play / FF / RW Amazon Music playback? When using the Fitbit system one gets reminders to 'move' if one has not achieved 250 steps in an hour (you can define the start & end hours), does the AW offer a similar system? On the Gear S3 & Ionic watch faces can be produced by third parties, I know that this is not an option on the AW, however those watches can therefore have 'health monitoring' that allow a constant display of steps walked, floors climbed, calories burned, and active time. Can any AW faces gives this sort of information, possibly using complications? If not via that method can any of that data be easily seen on the AW? Any info would be appreciated.
