Tried other people’s phones, updated iOS.. nothing. The phone just cannot see the battery as a Bluetooth device. Tried on my mum’s old Samsung and bingo. Recognized it straight away. Now I have to keep this old Samsung in my campervan to read my battery and do software updates. Hopefully it’ll hold out. Not ideal but better than nothing. Hopefully Epsilon will get their act together and sort out the app so it’s compatible with iPhone at some point. Very annoying ### 4/5 — Pretty good for me !! *2023-06-29, version 1.3.1* It does well for me but as advice to others, make sure your txt size isn’t too big because certain info can missed I.E. pairing passcode entry & serial numbers. To the developers, please can there be a way of displaying the Node ID in the app. Thanks ### 1/5 — It doesn’t work *2023-06-12, version 1.3.1* This app detects the battery but refuses to pair with it. Never asks for a pairing code, just a spinner until it times out. ## Frequently asked questions about Super B ### What information does Be in Charge 2 provide about my battery?
