Got to do a direct compare of (two) 10 III running android and sfos.
Phones were put into flight mode, and left overnight ( 8.25hours)
before after
X10 III Android 12: 91% → 90%
X10 III SOFS 4.4.72 77% → 72%
XA2 4.4.72(old) 100% → 98%
So probably fair to say that 10 III SFOS drew down 5x the current of either 10 III Android or the XA2
(I do not have Android app support installed. Location is off.)
More time has elapsed, and the Android phone has been out of flight mode
X10 III A12 FM 8hr,wifi+cell 27hr) + : 91% → 76%
X10 III SOFS (FM 44hr) 77% → 48%
XA2 4.4.72 (FM 44hr) 100% → 89%
So the SF 10 III draws more in flight mode, in a drawer, than the Android 12 does with wifi and cell running (and I am in a weak cellular location)
10 III had battery buddy running. Turned it off. 9hrs → 48%. i.e no change in %/hr
Turned them off for 24hrs
10 III 48% → 48%
XA2 89% ->89%
So no apparent drain when off.
It appears that Flightmode GPS performance similar to Android at first test.
Cold start acquire time >48hrs since last fix: 760secs. (Haven’t tried Android)
Re-acquire time after location turned off then turned on again
SF 45sec
Android 40sec (Android was restarted in flightmode, location off)
For comparison, some Android 12 running screen on current drains measured using GSAM battery monitor app. (Which has a lot of white screen)
Flight mode, Stamina mode, min brightness 108mA, mid bright 135mA, max 188mA
Stamina mode, 223mA
wifi,cell, not stamina,max bright, 262mA
