This is the daily ritual I have been following,
- Keep the phone charged during most of the day (I use wireless tethering most of the time so my battery use is probably higher than most people need)
- Manually suspend the phone at night.
- Wake the phone up by pressing power button every morning. If there was any SMS, the phone would wake up and receive SMS. It will wake up on first call, but we can’t pick up the first call while it is in suspend. A second call after the phone woke up we can pick. I have 40-60% battery left in the morning. Connect phone to charger. I have charger in my car and I have a power bank for traveling.
- Sometimes we need to reboot the phone if wifi tethering keeps breaking.
Additionally adding https://source.puri.sm/Librem5/linux/-/issues/425#note_205637 seems to reduce the number of usb resets and modem vanishing.
Even with this, sometimes I notice the modem has vanished, so I have to manually reset the modem using https://source.puri.sm/Librem5/linux/-/issues/303#note_181004 (this could be automated, but seems not a priority for Purism right now).
With a bit of effort I use it as my primary phone though losing some calls at times. I do have an android phone as backup in case I’m not reachable on my Librem 5.
