The USB charger is, as before, useful for powering anything that charges over a USB cable. Hardly worth mentioning, but it's one of those fringe benefits that makes you feel like you're getting your money's worth from a well-thought out product bundle.
Fully charged, Aliph says the Jawbone Prime will deliver 4.5 hours talk time, which sounds about right to me. Unless you're some manner of high-flying executive unable to spend more than five minutes off the road and phone (in which case why are you driving your own car?) I can't see battery life being a problem.
A charge to 80 per cent capacity takes less than an hour, which is pretty swift by anyone's standards and when not connected to a phone, the Prime will turn itself off after 15 minutes of non-use helping preserve its battery. Quick enough for a top-up over a leisurely breakfast, cup of coffee and newspaper in the morning certainly.
The Jawbone Prime can be connected to as many as eight devices, using the standard search, connect, enter the passcode (0000 - surprise, surprise) and go technique you're surely all familiar with. Usefully, two phones can be connected to the Jawbone Prime at once, handy for those who carry both a work and personal phone.
Or, of course, if you leave a second mobile hidden in your car away from a significant other. Not that I condone such behaviour, but growing up on American dramas has left me with the impression that at least one person in a good 80 per cent of all couples is being unfaithful.
But I digress; being able to connect the Jawbone Prime to two phones at once is bound to be a deal-sealer for some to my mind.
