Apple Watch on watchOS 2 not giving you the battery life you expected? Here's how to troubleshoot it!

During the watchOS 2 beta I went through some battery life issues. That's to be expected during a beta, and I managed to fix them and get back on the great battery life track. So, if you're having issues keeping your Apple Watch charged for as long as you like, whether it's from a wonky update or new features overloaded for the first time, here's how to fix it!

1. Watch your watch

The first thing peole do when we get new features is try them out. A lot. That means time lapse clock faces, native apps, and all the other bells and whistles. And if your Apple Watch screen stays lit up, and the radios stay broadcasting, it can give a false sense of battery drain.

So, before you do anything else, note down how much battery life you have left. Then put your Apple Watch down for 10-20 minutes. When you pick it back up, note down how much battery life you have left again. If there isn't a big change while in standby, you're probably okay, and your battery life will return to normal when your usage returns to normal (after the novelty wears off).

If your Apple Watch continued to drain and drain fast, even when you weren't using it, keep reading!

2. Reboot

Yes, it sounds like something right out of the stone ages of trouble shooting but sometimes a good reboot is all that's needed to kick loose the bad bits.

  1. Press and hold down both the digital crown and the side button at the same time.
  2. Keep them held down until you see an Apple logo.
  3. Let go.

Once your Apple Watch has rebooted, see if battery has returned to normal. If not, keep reading!

3. Re-pair

The single biggest cause of battery life problems with iOS devices occurs when they are updated and something gets glitchy. Whether it's cruft or corruption, bit rot or simply bad bits, a clean install —pain in the butt though it may be—is often the best medicine. This is the nuclear option. You will have to set up absolutely everything again, but since your data is backed up on your iPhone, you won't have to start complete from scratch.

And yes, this is the one that worked for me. From the Watch app on your iPhone:

  1. Launch the Apple Watch app from your Home screen.
  2. Tap Apple Watch.
  3. Tap Unpair Apple Watch.
  4. Tap Unpair [Your] Apple Watch to confirm.

You can also un-pair right on the Apple Watch:

  1. Press the Digital Crown to switch to the app launcher.
  2. Tap on the Settings app.
  3. Tap on General
  4. Tap on Reset all the way at the bottom.
  5. Tap on Erase all contents and settings.
  6. Enter your Passcode to confirm.

Once that's done, try your Apple Watch again and see how the battery lasts. If it's all good, you're golden. If not, there's one last thing to try...

4. Go to Apple

Sometimes hardware or software picks update time to fail. If that's the case and you live close to an Apple retail store. If you don't live close to an Apple Store, give 1-800-MY-APPLE a call instead.

5. More help!

If you're really desperate, put your Apple Watch into Low Power mode until you can get back to a charger. If you know of any other tips, leave them in the comments below!
