I’ve got a Boron running on the 1.4.2 firmware and I’m having some weird charing issues. Intermittently it will say “discharging” and stop charging the device, and then run the battery down to 0. If I unplug the battery and the device from power, then power it back up, then plug the battery in, it w…

This is common with Lithium batteries. The device actually only charges to about 85% to prevent overcharging, and adjusts the value in the console. If the battery is old and/or has been fully discharged, over time it will hold less charge than when it was new.

Particle ruined the Boron charging code in recent update; please see at least two recent threads about this. E.g.: [image] PMIC calls now catastrophically crash Boron due to Particle software update Troubleshooting Update: Today, I tried to confirm that the workaround de…

Thanks for all the replies. @Paul_M I’ve looked through a couple of those threads. Might need to do it manually to achieve the reliability we need, but unfortunately the documentation is lacking for the PMIC side of things. I’ve got a ticket in, we’ll see what that yields. I’m rapidly headed towards…

Hi @aklein24 , thanks for posting this (and for opening up a support ticket referencing this post). First, @picsil ’s answer is correct re: max charge reporting. Regarding the inconsistencies above, I will return here and in our ticket for an update.

Sorry for late responses, I hadn't thought about this much for awhile because I hadn't seen any issues with my devices lately. Well, deployed another 1.4.2 Boron and it's on VIN power (5V) and a LiPo battery and it drained the battery down and is now offline. [image] I'm reading through this threa…

potentially? I’m having a hard time deciphering what exactly I need to do to fix the issue, I’ve read all those posts and I can’t figure out exactly what to do. My devices are on 5V power all the time, and I haven’t touched any PMIC settings, so I’m not sure why it decides to drain the battery down …

alright, I’ve troubleshot a little more, and I’ll give a little more thorough background: I am power using a 5V 1.5A power supply through the VIN pin. I use the EN pin to shut the device off using a switch I’m using one of your LiPo batteries if I shut the device off using EN, while the device is …

and I found a kinda sorta workaround though I don’t know what the fix is… void setup() { detachInterrupt(LOW_BAT_UC); // Delay for up to two system power manager loop invocations delay(2000); // Change PMIC settings PMIC pmic; pmic.begin(); pmic.setInputVoltageLimit(4360); // for 5V…

[image] aklein24: if I shut the device off using EN, while the device is on battery power, it will not begin charging again unless I unhook the battery while the device is unhooked from power, power it back on, then reattach the battery I was about to tell you that's not the normal case, unti…
