https://devzone.nordicsemi.com/f/nordic-q-a/66604/thingy-91-turns-off-when-unpluggedI tried to run my Thingy91 off the battery but it shuts off instantly. My questions is if the battery charging functionality is in the firmware or hardware? Trying to figure out if it&#39;s a faulty battery or if I can flash something else on for it toen-USTelligent Community 13Thu, 01 Oct 2020 14:07:16 GMThttps://devzone.nordicsemi.com/thread/272587?ContentTypeID=1Thu, 01 Oct 2020 14:07:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e855b2c8-0d91-44f6-9205-37e05dc30c1aImagiSam<p>the device is on. I guess, it must be either a faulty battery or perhaps a worn connection. This project is purely to evaluate a project and I don&#39;t need the battery so much.
