Well this old person has had to donate my backup paper maps to people whose phones were out of charge or who had no map at all and wanted to know where they were.

NB When in Scottish mountains I take:

- An iPhone with offline OS maps

- An external battery for my iPhone and cable

- A paper OS map in a waterproof map case

- A printed A4 backup of an OS map in a plastic bag that I can give to others or to use if other maps become unusable (e.g. blown away - which has happened)

80% of the time I just use the iPhone - still have to use OS map and compass occasionally when things are particularly exciting.
