I’ve done some more tinkering.
Now it looks like the projector kept on shutting down to protect itself from overcharging the battery.
The reason I believe this is as most of us had the problem with the battery charge never being shown correctly on display. In my case pretty much consistently about 96%. Once I unplugged the USB-C power adapter I had no more outages. I ran the projector unplugged fine from 96% to 76% without issues. Then I plugged back in the power adapter kept the projector running and it charged while playing without problems to 100%. That then also ruled out any possible issues with the power adapter.
Several hours later I turned the projector back on and it showed battery drained to 98% even though it was plugged in constantly. But only when it was turned on it charged back to 100%. For now it has run without another forced shutdown. The difference this time is it actually charges fully to 100% vs before just showing max 96% and because of that tried keeping charging triggering a protective shutdown to prevent overcharging. At least that’s what I believe happened here and only Phillips can confirm.
So, based on this I can’t tell if this a new behavior because of this v1.1.05 or is just a lingering problem with the charge display and just has caught up with me.
For now I’m up and running again, but can’t wait for this charge display and handing to be fixed soon in an upcoming update.
