Nora - XC9128 & energizer lithium

Does using XC9128 PSU help extend battery life when using energizer lithium?

Also in the wake tests was wifi off?
E.g. with a lithium I get 70K offline wakes.
Or is this a mix of wifi Off and periodic On updates to cloud?

Thanks as always

If you use energizer E91 lithiums the XC9128 does not increase number of wakes. We’ve added an example discharge curve for three different types of batteries on the Nora devwiki page:

As you can see almost all of the wakes occur above 2.5V. I would recommend an undervoltage lockout so prevent operation below the 2.5V cutoff.
