Modem modules are usually directly connected to the battery because 2G may draw too much energy during transmission pulses. Otherwise one would need a 3.3V regulator that can handle 2-3A pulses and still have no significant energy loss.That seems unlikely. Surely the modem chip is connected to the 3V3 rail, not directly to the battery.
What makes you think it might?will this change if the new universal modem is used ?
What update? A software update is the most obvious meaning of that word to me, and I don't see how that would affect the modem adversely outside of a regression occurring. There's also the plan to replace the modem with a new universal modem in a hardware update, but that's a different modem which won't have been using outside of an integration test when assembling the unit.How do you want to take care that the Update dosnt harm the allready used Pyra Modems?
I assume this doesn't apply to the standard model? I just charged mine to 100%/4.2V to see if it was just my memory being wrong.To avoid this we have to stop charging at 4.1V which is ca. 80% fuel level. And the fuel gauge chip and kernel drivers are not aware of this and report 4.1V as 80%.
HNS said "But the Modem sends an overvoltage message at 4.25V and turns itself off." i remember the possibility of a different Modem package. i was wondering if the alleged new modem chip had a different behaviour or ran at a lower voltage.What makes you think it might?
As far as I understand, even if something not patched is installed, the Modem will not be damaged, it just shuts down itself if there is overvoltage, so in the worst case it will just not work, at least until the system is patched again.I meant the "Sudo apt upgrade" update, : If i remember correctly, this might also update the Power Controll Software..
