    My series 4 usually last me two full days, for some reason today I’ve noticed it’s been draining faster than ever. I took it off the charger at about 545 this morning and I only have 38% battery left. How do I figure out what is suddenly draining my battery?

    I’ll say this, for some odd reason, sports apps like MLB and NHL suck the life out of the battery quick. Messaging apps like Facebook messenger are not very friendly either.

    Do a restart holding the crown and button in and keep them pushed until you see the Apple logo. That in itself might fix it.

    Remove 3rd party apps and reinstall one at a time until you find the culprit.

    I have found that when I put on the "fire" watch face (full screen) - then the battery was gone by about noon (that's when I got a low battery warning). I was very active that morning and the phone probably thought many times that it should turn on the watch face because I was looking at it. But once I switched to a different face, things changed dramatically and since then I finish a day with about 60% even if I go to a rock climbing gym for an hour and a half and track my climbs all the time.

    Beware if you see the watch face display the charging cable icon.

    My first Series 2 did a sudden battery drain, then displayed the charging cable and telling me to charge the watch. No matter how long I left it on the charger, the batter just would not take a charge. Apple replaced it under warranty with a brand new puck that I am currently using while my S4 is on the way.

    If you see that cable, take the watch in right away and get a swap started.

    Just giving you the my/worst case scenario.

    My Series 2 watch has been fine during the day, but for whatever reason, it drains 10-15% every night (when it's not on my wrist while I sleep), which is like 2-3 times more than normal. As far as I know, I haven't done anything new with the watch or installed any apps, and hard resets haven't fixed anything...
