Hi!

Bangle2 2v11

Could you try to update to the latest stable firmware, 2v12? You can do it trought the Espruino Web IDE (top right icon, flasher)

edit by Gordon: Please don't use the IDE to upgrade firmware unless you have to. Use the firmware update app at https://banglejs.com/apps#fwupdate - instructions are at https://www.espruino.com/Bangle.js2#firmware-updates

Well, the fallback is to just Install Default Apps to reset your Bangle and see if that helps... But:

• Does the Bluetooth icon keep changing color? If so it'll be some device that keeps on connecting/disconnecting as you suggest
• What are you Settings->System->LCD settings set to? Maybe turn Wake on... off for everything apart from the button
• You could ensure your LCD timeout in that same menu is set low
• What apps/widgets do you have installed? Things like sleep tracker will drain your battery fast at the moment.

Other things that can run the battery down quick are if you have the 'recorder' app left on (which turns GPS on) or if the heart rate monitor is set to on in 'health' settings. Setting the health app to 10 mins gives you a good balance of battery life and accuracy

Updating to 2v12 firmware will probably help you too.

I am on 2.12 and see the lighting up also.
In settings LCD i disabled all but button (esp. twist).
I still can reproduce the lighting up through shaking, and its not much that is needed:
When laying flat on a table and putting something heavy on the table, thats enough.
Need to search where else the trigger can be (some app?)

Hi Alessandro,
Thanks for the instructions (I hadn't realised there was a new version), I've installed 2v12 and will see whether this solves things.

I have added a question for battery saving tips in the wiki.

@gfwilliams Sorry I didn't know that the flasher is not recommended. I read about it somewhere and I thought it was the way to update!

@alessandro it's fine - thanks for helping out! The firmware updater app got sorted properly a few weeks ago, and it's just a bit easier and safer (especially with recent iOS versions having issues with NRF Connect)

@hughb thanks!
