Samsung Galaxy Watch 7 battery life hammered by Samsung Health Monitor app
I noticed about a month or two back that my Galaxy Watch was suddenly no longer getting its two days of use out a battery charge. I do keep my watch usage quite light, and normally have the Wi-Fi off, display set to lower brightness, etc, so 2 days is usually fine. I do use watch with the Sleep For Android app that monitors sleeping heart rate etc, and that does chew about 11-12% during the night, but that has been my normal usage.
I thought at first maybe it is the battery ageing, but it is not even a year old yet. But checking the battery usage stats showed that the Samsung Health Monitor app (not the standard Samsung Health app) was chewing the battery by a good 3%, higher than any other app. Rebooting had not helped either. Seeing that app is only used for ECG, sleep apnoea and blood pressure, not of which I had used for quite a while, that app should be idling with no battery usage.
I tried to delete the app, but it deleted off the phone but not from the watch at all. It would also not disable properly, nor could I turn off the background usage toggle. In the end, I used the ADB command to manually delete the app. And wow, now I have a full 2 days battery use again, plus a little extra.
It shows again what impact badly behaved apps have on hardware. Ideally, this app should not be using any battery power if I don’t have sleep apnoea detection active, or if its parent app on the phone is deleted.
