While Jawbone suggests the battery should last up to six months, it feels more like two to three is a better guide, and that’s dependent on the strength of the battery you buy. One cheap battery barely hit a little over a month, so we replaced it with something a little more expensive. As you do.

Technically, though, the Up Move still in more or less the same condition we first received it in, and that’s after being on a person’s body for the space of six months, which isn’t bad at all. It tells the time and tracks data, but while it says it’s working, the Up Move isn’t without its fair share of problems.

For instance, synchronising the Up Move is done automatically, but much of the time, it feels like the Up Move isn’t working at all.

We know that it’s supposed to automatically synchronise, an action that happens thanks to Jawbone’s use of Bluetooth LE. That said, we’ve actually noticed that syncing often has to be forced, with the app lagging behind and refusing to connect to the Up Move.

You’ll hit sync and the app will say it’s working, but nothing will happen, and the steps you’ve gathered over the day won’t appear. So you’ll do it again, and again, and again, and again, and eventually it might actually synchronise the way it was supposed to in the first instance, although we found more likely that it would do it if you deleted the Up Move from the app and re-paired it.

Sometimes this needs to happen several times before anything can happen, and it’s an issue we’ve found on both iOS (iPhone 6) and numerous Androids. When it’s happened and the wife has worried about her missing activities, we’ve paired, repaired, tried on a different device, and found that something wasn’t working right.

Was it the app? Is it the hardware? Is it some mystical force that doesn’t want activity information synchronised (our guess is no for this one).

And that leads us to the problem with Jawbone’s Up Move six months on: it’s fairly unreliable.

The time is 11.55. Give or take.

It’s a shame, too, because the Jawbone Up Move has so far been the best, the most social, and the most easily accessible of the fitness gadgets we’ve seen, providing a tiny size and wrist-bound form-factor that manages to also offer up a wrist watch when you need one, some excellent social networking options allowing you to connect with friends and see how they’re doing (and cheering them on), and a price tag that is hard to go by.

At $69 — which is where it launched and where it remains at current street prices — the Up Move is difficult to ignore for someone interested in fitness gadgets, especially since it does what a lot of the cheap gadgets do — steps and whatnot — but also offers a little more.

But the longterm durability appears to be a little out-of-sync, just like the Up Move’s inability to sync easily over a long period of time, and that makes us wonder how well made it is internally, rather than externally.

On the one hand, the battery is very easy to replace, requiring a CR2032 battery that you can find from any supermarket, so that’s positive. On the other, however, the constant synchronisation problems give us pause, after all, no one likes to think their details and fitness activity logs have been lost to the ether, and sometimes that’s exactly what the Up Move feels like it’s doing.
