I have a K9. I’m getting terrible battery life - 4.5 hrs with no services, wifi, BT, or sim. I did a reset under Settings>Reset Equipment, and a couple of interesting things happened. Unfortunately, I still have bad battery life, and if anyone has a suggestion, I’d appreciate it. The weather and barometer now work for me where they didn’t before. Only, I need Fahrenheit - Does anyone know how to change units? Second, I now get into the menu with a simple tap on the homescreen rather than a pulldown wipe.
Interesting, if it helps anyone.
