Updated Power Statistics when compared to 2021 here are 2023 numbers.
Environment: wifi hks off, wwan 4G on, open vpn connected, various apps running (mostly .deb apps but flatpak is installed on phone), screen brightness 85%, used indoors, on battery starting with 100% charge to 0%, suspend on at 5min, blank screen at 2min, sparklan modem.
Steps to repeat during entire runtime:
- occasionally pick up phone turn on screen, unlock as needed,
- make sure its reconnected to 4G,
- check pureos store for updates once,
- start syncthing check web UI over firefox once and sync,
- read news ~10-15 times using Feeds RSS app, mostly Guardian news,
- receive ~15 messages,
- send ~10 messages
- when phone is suspended and you receive message notification unlock and check message,
- check email ~5 times
While doing that the phone lasted almost ~6hours at room temperature. The flat lines indicate suspend operation.
- Observation last 20% rate of charge drop increases, probably needs adjustment to limit current use as battery voltage starts to drop towards the end. Can this be done with a driver update?
- it didnt really seem to matter what i used the phone for as charge drop rate mostly remains constant, so no one app being abusive to the battery (which would be an outlier and shouldnt be included in this type measurement anyways)
New Power Statistic from today, Wifi On but disabled in software also in addition to above used:
- in gnome software install one app (and search for 1-2 apps),
- uninstall weather .deb app in terminal,
- launch flatpak weather app and check weather
Observations:
- battery almost lasted 5 hours
- similar observations to above apply
- 12 hours is not possible on my L5
