Well, our devices are new Gsmart ones, that are currently marketed by Mercury. They tell us that drivers keep losing plots due to battery going down by as little as 10% starts to cause this. These things are mobile telephones as far as I understand it, now mobile phones don't stop working correctly until battery discharges completely. In this case 10% discharge and drivers have to start calling control to adjust them on a plot. Again, those are not old XDAs, we just got them, together with this rather useless satnav, works Ok but you can't see anything as lettering is so small. BTW our old XDAs had no plotting issues, new ones do.

I think I may be able help with an answer to your original question.
Devices like the XDA were the best you could get several years ago and were therefor a good choice. Back then, data usage was incredibly expensive so software at the time attempted to minimise its use and this process had the added advantage of prolonging battery life. There’s always a compromise between how active the device is and how long the battery lasts and that’s still true with modern devices.
Imagine you had an old word processing program running on Windows 95 PC and what would happen if you tried to upgrade it to run a modern package on a newer operating system? The processor was never designed for this sort of thing and its power consumption would go through the roof with what it’s now being asked to do. In contrast, modern processors and GPS engines are not only faster, they’re infinitely more efficient and so are able to do a lot more while using less power.
If we run our application at a Mercury site, the first reaction is that it’s a whole load faster but an hour down the line there’s a queue of drivers all with flat batteries. So in fairness to Mercury, it’s your old devices that are just not up to the job and the answer isn’t to fit new batteries, the device itself needs to be replaced. The proof of the pudding is that last week we carried out trials on one of the newest devices available and even with the high demands from our app, it ran for an incredible eight hours!
Hope that gives you some hope.
