I had a Charge HR for almost a month, got one for my wife too. I finally returned them this week. They're nice to wear and pleasant to use, but the battery lasts one day and the reported steps/calories/distance is basically science fiction.

I dunno - I'm finding it to be decent enough.

e.g. Monday was Fitbit:13293/9.54km, Garmin920XT:13612/10.6km, iPhone:12529/9.8km.

Tuesday was similar - Fitbit:24305/19.85km, Garmin920XT:21928/18.6km, Moves:22097/18.2km

You must have had faulty devices. My wife and I both have one as well and the battery lasts about 5-6 days before needing a recharge.

I'm inclining towards this option, too. I didn't think it was likely because both watches (can you call them that?) had the same issues. This reminds me of my experience with Razer: out of 5 mice bought (4 abyssus, 1 orochi), two were faulty.

The reported distance is basically fiction, of course. It's not a GPS device. It's an estimate based on how many steps it thinks you took, and the average distance an average person goes in that number of steps.

As far as I can tell, steps/calories is roughly accurate (eg, not off by much more than, say, 10%) compared with other devices (my chest strap HRM+GPS device, stationary trainers, bicycle computer). Close enough for consumer use.

I echo the poor battery life. I forget what it's rated at, but I get barely 3 days. My old Nike Fuelband was rated at 7 days but I could push it over 2 weeks.
