That new watch is about to hit the shelves although I can't help wondering how long this version will be around?
I assume it will be on a quick refresh cycle to be faster, slimmer and with lower power use?
Maybe in a year there will be a 24 hour version after the consumer feedback from the first one?
The apparent need for an 18 hour recharge may just be a wind-up?. A watch that lasts less than a day? It goes to sleep instead of monitoring it? Or maybe the answer is to have two watches so that one can be on the charger whilst the other is in use?
I'm wondering what battery technology is being used?
If lithium polymer, we might expect that effect where the battery starts to lose capacity after 200 to 300 charge cycles. The battery university test of eleven such batteries from smartphones shows a 15%-25% battery capacity reduction after 250 charges - that's about nine months and would show a duration reduction to about 15 hours. Now if the watch (my suggested next version) started at, say, 30 hours then it's less of a problem. I suppose, as they say, time will tell.
The next thing I'll want to see is inductive charging, where the various devices like iPhones, watches similar products can be dropped onto a pad, rather than plugged in to be recharged. Presumably all the iOS products will be getting this soon, although I suppose it might require some plastic/ceramics/glass for the case?
