Hmm, I don't understand the question. Those five minutes would be the total time of active use during the whole day, with the display on. Typically, this would be in small sessions of 30-60 seconds each. And yes, if you turn Anelok on but then don't use it, or forget to turn it off after use, it will quickly drop to lower-power modes: http://downloads.qi-hardware.com/people/werner/anelok/tmp/?C=M;O=D E.g., after 10-30 seconds (depending on whether it shows content you may just look at for a while, e.g., a password, or whether it shows something you're expected to react to quickly, e.g., a selection list), the screen will go dark. (State DARK1.) If you're not done yet, you just touch the slider and the screen content comes back instantly. If you don't react to Anelok going dark, power management assumes you're not in a hurry to have it back on and powers down the display panel. (DARK2) Recovery from DARK2 takes longer because there are delays in initializing the display hardware. In DARK2, Anelok waits just one second to make sure the system has settled in a stable state, then switches off the boost converter (READY). All this happens within 21 to 41 seconds after you last touched the slider. If you're at the account list, your current consumption between last touching the slider and READY would be 15 mA * 10 s + 3.1 mA * 10 s + 0.7 mA * 1 s = 181.7 mAs READY is already quite low-power (130 uA), so it stays there for a minute in order to be able to respond quickly to touch screen activation. After that minute, it reduces the sampling rate for the touch screen (STANDBY). READY is thus another 0.13 mA * 60 s = 7.8 mAs (4.3% of the 181.7 mAs it took us to get to READY.) Also, when "on" (ACTIVE), the MCU sleeps (LLS state) whenever it can. But the dominant power consumer is then the OLED panel anyway. - Werner _______________________________________________ Qi Hardware Discussion List Mail to list (members only): [email protected] Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
