Other things I use are a chip card for local train tickets (it never runs out of battery) and a PC with a solid real two-factor authentication based on chipcard and an optical TAN generator for banking.
And when I am exploring new areas on the bike, I sometimes just use the old paper maps - they don’t run out of battery either, and they give s much better overview than a tiny phone screen.
