Jolla does behave strange when low on battery

Just yesterday I tried to drain my Jolla to below 6% to have the battery have a good learning cycle - below 7% I recognized strange behaviour (like when you power a chip with less than the required voltage). If the voltage is too low to work properly, the phone should shut down and not think it is still having 3% above its limit left, right?, 30 hours after my last charge it went down from 54% to 14% in a heartbeat (no idea if it was minutes or 10minutes but I did not recognize it in between) when it suddenly started to play up again, pages getting stuck while scrolling or even when flicking/pushing them they get stuck after some 10% movement. I know that some of the heavy drain can come from indexing and stuff but really why does it need to index after a 6MB update, why does it even need to restart for a connman patch?

Without any more details on strange behaviour there is nothing that can be said...

Why were you doing this anyway, were you trying to calibrate the chargemeter or what?

@juiceme kind of, @Philippe De Swert how about it releases a touch even without lifting my finger, the whole user experience drifts to WinVista - slow unresponsive and is back to normal, fast, responsive when I plug it in... (what part of "like an underpowered chip" did you not understand?) just like a voltage regulator is trying to do his job but when the processor is hogging it it just has not enough juice left to maintain everything - like a HDMI2VGA converter behaving strange when you forget to plug its power in - a walkman slowing playback - a wifi signal gets packetloss, your jolla behaving like it ran out of power but the regulator is still able to keep the system running, just not on full speed anymore (did that answer the question?)

@chemist: Ah you mean "underpowered" as in seemingly not enough computing power... I was wondering what you meant with behaviour from a chip that does not get enough voltage/amperage...

kind of yes, like when you undervoltage your CPU on your desktop - funny things might happen (that if it not just freezes)
