Wa.. i PO with Samsung already arrived lo.. Lol. Been using for a few days on and off. since i still have my Galaxy Watch 5 Pro hahaa..  Undecided to sell or keep my GW5Pro.. haha. Main thing is hardware battery wise GW5Pro have more, although my GW6Classic can last 2 days also.. Same as my GW5Pro.. Hmm.. Only issue is i use my GW5Pro more often than my GW6Classic.. will see how over this few days, just bought new armor strap and TG.. xD 

Edit: Oh, i thought they start shipping GW6 and GW6 Classic together?     

Yep. 47mm.
So far it is, because i rarely use my GW6.
At the moment cant, because i didnt use my GW6 for 3 days already. lol. Last used on Sunday. Then left on my desk because i go work with my GW5Pro. Usually use my GW6 for going out. xD Will update when i can hehe 

howuch dmg ?

So far used for a day; every Sunday, and on certain occasions, like yesterday public holiday, the watch can last me a day. By evening will have around 30-40% battery. I started using it at night before I sleep till the next day. Then morning use till evening/night time till i reach home around 7/8pm. By that time battery around 30-40%. Heart Rate monitor is on 24/7. Step tracker is on 24/7 also. My GW5Pro can last me usually 2 days. By 2nd day will have around 40% battery, and then can last me till evening, if i set to low power mode. If not before 5pm will have less than 5% battery. A few times already turned off before 5pm lol.
