Hi!

Spent most of the day at the desk, working. Nothing different to the past few weeks, but no exercise activity.

Switched to modular face, and replaced Just-Press-Record.app from the dock, and removed it as a Complication. That's the only change I can think of, compared to what I have been doing daily - at least during our Summer vacation.

That said, usual number of notifications, reminders etc.

At about 7pm, after being up since 6am, glanced at the battery percentage, and it was still fixed at 100%??

Finding that odd, popped it on the charger - green ring came up confirming it was 100% charged, and left it on to charge for about 20 minutes - figured that might 'reset' things...

It's now 9h50pm, and it's STILL on 100%

Switched it on/off, no change.

I was one of those that jump in when 3.1(?) dropped, before it was pulled. Not sure if that's relevant, but figured I would mention it.

I know the battery life has improved of late, but this surely cannot be right?

Anyone else seeing this? Suggestions?
 
The monitoring circuit likely needs calibration. Run it until it dies completely (shuts off) and then recharge it. This will likely reset the battery monitor.

That's some stellar battery life. But I truly believe it's not properly calibrated or providing an inaccurate reading.

Thanks.

On 83% this morning (05:32). So at least it's dropped off the 100% bar.

You reckon I should still run it down to recalibrate?

Also, if I recall correctly, when recalibrating you should let the battery recharge from 0 to 100% without taking it off the charger. Is that right, Julien?

Correct.

...To maintain accuracy, a smart battery should periodically be calibrated by running the pack down in the device until “Low Battery” appears and then apply a recharge. The full discharge sets the discharge flag and the full charge establishes the charge flag....

Thanks for the tips. All appears to be back to normal today - currently on 63%, 22h25 my time. Will see if it misbehaves, and then do the recalibrate.
