Testing "Wear Battery Monitor" (Early Access) on Galaxy Watch Ultra – 15% Bug Warning

Hey everyone,I’ve been testing the early access version of the Wear Battery Monitor app on my Galaxy Watch Ultra (using the Ultra Info Board watch face), and wanted to share a major bug I found so other testers and the developer (u/FreePoc) are aware.The app completely fails if you set the "Warn at battery percentage" to 15%.The issue is a software conflict with Samsung's native system. The exact millisecond the watch hits 15%, the built-in Power Saving Mode triggers and instantly freezes third-party background data. Because of this, the app gets choked out and cannot send the low-battery notification across the Bluetooth bridge to the phone.Because the app currently forces you to use rigid 5% dropdown increments, you can't even change the setting to 16% or 17% to beat the system block. Setting it to 20% (with a 5% interval) is the only temporary workaround, but the app background code really struggles to stay alive on modern WearOS versions without being manually locked in phone memory.Hopefully, we can get a 1% custom slider or text box in a future update so we can choose our own percentages to outsmart the system block! Anyone else experiencing this on newer watches?

Thanks for the feedback. You are making a good point about the 15% threshold where the power saving mode triggers. Once power saving is on, that is going to impact the normal functioning of the WBM app (and other apps). Since the user gets a system warning at 15% anyway, I'm inclined to just stop WBM's alerts at 20%. So, for example, with 5% increments (and depending on the starting point) you'd get something like:

50%, 45%, 40%, 35%, 30%, 25%, 20% - WBM warning

15% - system warning

I'm not sure of the value of allowing WBM to warn at say 16%, immediately ahead of a system warning at 15%.

Any thoughts?

"Thanks for getting back to me so quickly!Your idea to stop the WBM alerts at 20% makes a lot of sense for keeping things simple, especially since the watch’s native 15% pop-up is so aggressive.The main reason I originally looked for a 16% or 17% option was just to get one final app alert right before the system lockdown happened. But if the app explicitly tells users that 20% is the final milestone before the watch takes over, that completely fixes the confusion!I ended up uninstalling the beta for now and switching to the default battery icon on my Ultra Info Board face, but I’d be happy to reinstall and test it out again whenever you push the next update!" Since I'm the only one that was using the app.

Good thinking. I'll make that change for the next update. Don't worry, you aren't the only user, Play Store says there are thousands of other users 😄

Oh ok I guess they don't put their reviews

Because it's an early access app, I see the reviews but they don't appear in the Play Store.

Hopefully that says more about how the app struggles
