Weird battery issue

[maskedcarrot]

So I am not sure if I might have a defective 360 or not.

This happened twice to me this past week. First I charged my phone before bed to 100%, and turned it off when I went to bed. I didn't use it the next day, but the day after that I turned it on in the morning and my battery was at 89%.

Then last night, again, I charged it to 100% before bed and then turned it off. When I woke up this morning and turned it on, my battery was at 94%.

How can the battery discharge like that when the device is actually OFF? I lose 6% battery overnight without the unit even being on.

1) Why are you turning the watch off instead of just leaving it alone?
2) Battery indicators are not 100% accurate, especially when the device is very new or very old
3) Booting or rebooting the watch uses a significant amount of power.

same thing here. i charged it Sunday night shut it off then this afternoon (Tuesday) turned it on to find it at 91%. i know with my tablets and phones they can be off for literally weeks and when i turn them on i find them at 99-100%

I turn my phone and watch both off at night because I don't use them when I am sleeping. The same as the reason why I turn my car off when I get home instead of letting it run all night, and also I turn off all my lights in my house when I go to bed at night. It saves resources.

Sorry for the sarcasm, but I just had to. hehe but I'm sure my point was made.

Same here. My phones don't change at all if I keep them off all night. Sounds to me like either poorly designed batteries, or something in the watch still drawing power even when it's off.

If you think you are saving energy or something, it might amount to $0.05 per year? Meanwhile, it is a lot of unnecessary hassle. Of course, it is your time

My phones don't change at all if I keep them off all night.

And your phones don't have an ultra-tiny battery such that booting them sucks a considerable amount of power from them.

Doubtful. When it is off it is pretty much off. The amount of power drawn when off is extremely small- it just has to monitor a single, soft-on button (like most electronics). And idle/off loss from a Lithium battery in 8 or 12 hours is probably in the 0.07% range (irrelevant).

The battery meter is not THAT accurate, and booting the watch takes considerable resources. It doesn't seem all that mysterious. If you insist on booting it every single morning, then wake it and put it on the charger immediately so at least most of the time it is booting, it is using power from the charger instead of depleting the battery. Then when done (and it might take another 30 seconds after it SEEMS to be finished to really be finished), strap it on.

Sorry, but I just don't buy that argument.

Having it off overnight the watch will use about %5 battery, and I had it off for 2 days as I said in my original email and it discharged around %11.

So as you can see, booting the phone has nothing to do with the argument that it uses more energy to boot up being as the longer I keep it off, the more battery seems to be used.

I shouldn't have to top it off in the morning because it shouldn't be discharging with it off.

My watch was just showing 84%. I powered it off then powered it back on. Gave it a couple of minutes. Picked it up and it showed notifications for an email and a couple of appointments. Read them and dismissed them. My battery was then showing 83%. I'm just sayin'....

I repeated that test here and got similar results. It was 78% then powered it off, waited a min, then powered it on, waited for it to be really connected/normal again and checked and it was 77%. This used to eat several percent on my 360.1, but the 360.2 has a larger battery and is more efficient on top of that. So just the booting alone can only explain about 1% of his 6% overnight loss.
