Hi all!

So, I recently got an Apple Watch Sport. It has been working great, and I've been getting 2-3 days on a single charge. Well, last night I put my watch on at 4pm. I first rebooted (powered off and on my phone and the watch - hadn't don't it in awhile). At about 8pm, I got the message from the watch asking if I wanted to go into power reserve mode at 3% battery life. My phone battery, however, was still ok.

Any idea what happened here? I recharged it last night and it is currently at 100% now. Do I need to do something else to the watch or phone? Has anyone else experienced this?

Thanks much!

I have had my watch since Apple released them. Normally I can get nearly 2 days of use out of it, but in the past year+ there was one day it drained really fast and I didn't make it through a day. Don't know why, it didn't get hot or anything like I would expect if something was draining the battery fast.

Anyway, it hasn't happened again. I think it will likely be fine.

Every now and then, you get a really bad battery day. Mine has probably done it a couple times in the past year. I would not worry unless it repeats itself more regularly.

That's why you should be charging your AW nightly along with iPhone. Some days are more battery intensive than others. Also, it's not good for Li-Ion battery health to squeeze it to the last drop.

Happens to me a few times. I think a major factor has been app updates. At work I'm on wifi, but when I updates apps, sometimes the watch gets hung up on these and drains my battery. I noticed that if I save the updates until I'm home, I'm good to go. I tried this a few times and everytime I would update apps at work wifi, watch drained faster.

Another thought ... Is it possible you didn't seat the charger properly the last time you charged it? Maybe you assumed it was charged but it wasn't.

That has happened to my wife. The magnet isn't that strong so it's easy to misplace it such that it's not actually touching, especially when resting it on its side on a dock.
