Thanks for your help, the photo shows exactly what I remembered from my own screen a while back (it wasn’t a figment of my imagination after all!!) trouble is I can’t replicate it now, I think there’s a fault in the system as I can set a route with Electric Intelligence turned on but I only get the ETA and distance info, the battery info is missing. If I tap the screen on the info box, shown in your photo, a box showing ’route overview’ appears and at the top it says it’s ‘calculating intelligent route’ with a rotating circle but it never completes the task.
I didn’t remember that it’s the charge remaining at destination that’s shown there so you’re right it’s not what I need anyway, however your other suggestions are certainly worth a try.
Your theory on the reason for the hard to see battery percentage is interesting, it does seem odd as all the other info on how far you can travel is either really vague or hypothetical and based on previous distance covered. Relying on the percentage figure on its own could certainly result in the problems you noted but my method ( combining it with the real time consumption dial numbets) maybe requires some mental arithmetic but at least I know how much I need to alter my driving to eke out the remaining charge.
