Battery Life and 6030 Update

[eried]

Having the battery adapter I was able to test this futher and it seems there is a problem (but I can't confirm this precisely because I didn't checked accurate consumption of standby before updating the firmware):


So, precise standby consumption is 6 mA for new firmware.

Having this in mind, we can estimate the hours the calculator will take to drain all the battery (rated at 1500 mA, but mine 'holds' 1677 mAh empirical. I used a loss of 10% just to represent the internal battery drainage, changes in ambient humidity/temperature, etc):

So for some reason, idle time has been reduced from about 47-42 days to 10 in optimal conditions. (This does not explain the sudden total drainage, but this also happened with the old version so it might be a coincidence).

As reference, with the old firmware estimated idle consumption was 1,47 mA:


So... something changed in the idle consumption. Having in mind that when you see the FULL battery indicator, this is a value between 75% and 100%, then the real days your calculator will have remaining is about 7 days (having a battery with low wear).

Related with this, highest consumption is with Advanced graphics apps (it never goes to "idle") with 151.4 mA (@5.8V, or about 0.14A prior to the linear regulator from the supply at 6.2V). This is pretty similar to old firmware (captured at 5V, so no problems here).
