Ask Me Anything about not having a true screen on your phone.
And chatting apps like Telegram and Whastap ?
The only downside is that, on some maps, the grey-water is the same as the grey-road and it happened a few times that I thought a canal was a road when doing bike trip.
Google Maps is working but sometimes loosing the position, probably due to the fact there are no Google services on the smartphone. So Google Maps is very unreliable. It may loose positioning in the middle of a trip (suddenly, position is not updated anymore).
Well, really good to degooglize yourself ;-)
Never tried Spotify nor Waze nor Telegram.
Whatsapp was working if I remember well but I’ve deleted my account year ago. Signal is working fine except for notifications which are sometimes held until you launch the app. This doesn’t happen all the time, I suspect the aggressive battery "freezer".
For me, it is a feature as I’m disturbed less (the phone is in silence mode most of the time anyway). If I expect a message, I simply open Signal before locking the screen.
Note: there’s a way to forbid freezing for specific applications if needed. I just didn’t wanted to do it.
Using signal has not been always easy. See : https://ploum.net/2023-03-09-losing-signal.html
There’s also a "super saving mode" which allows only 6 apps, no notifications. I use it during long bikepacking trips, recharging every other day when stoping for lunch in a restaurant. It is great. Also, I leave the "super saving mode" if I need to use another app.
So it is perfectly possible to get very long battery time but you need to really configure it and figure out how to use it.
I’ve lost a lot a battery time by disabling freeze for Adguard VPN. In day to day use, I prefer to use more battery and send less data to China (the stuff is full of spyware). Even with that, I charge it every three days but I don’t use it much (which is the goal)
