Hi Mark

Are you using Microsoft Exchange Calendars on your iPhone? If so, I can offer some suggestions.

Hello markusfromeaston, I have the exact same issue with my watch after the iOS9 upgrade. It has been only 6 hours since a full charge (and nearly no use) of my watch and its battery is dead. My iPhone 5s is also going through battery at least twice as quickly as normal, after the upgrade...but it still has 60% after 6 hours.

I do use an Exchange mail account with my iPhone, so I have tried to turn off the mirroring with this account to the watch to test if this is the cause...unfortunately, my charger is at home so I have no way to recharge the watch until this evening.

As you are using Exchange Calendars, try some or all of these (which have worked for others):

• Archive your Exchange Calendar for all items before today.
• Remove / delete all old inbox messages about calendar invites (accept and decline notifications).
• Create a rule in your Outlook Mail account that moves all future accept and decline replies - immediately upon receipt - into a separate mail folder that does not sync with your iPhone and Apple Watch.

This potential solution has also been tried, but has not yet been reported back on, so you may prefer to skip it - especially if you have followed all of the previous steps:

Remove the Exchange Calendar from your iPhone, check it for problems (and resolve them), then replace it:

• The Calendar Checking Tool for Outlook (CalCheck) can check your Microsoft Outlook Calendar and items for problems / potential problems.
• Information: https://support.microsoft.com/en-us/kb/2678030
• Download: http://www.microsoft.com/en-us/download/details.aspx?id=28786

After making changes:

• On your iPhone, in the Apple Watch app, go to: My Watch > General > Reset > Reset Sync Data (process runs in the background - allow a minute or so).
• Restart both your iPhone and Apple Watch (to restart Apple Watch: Press and hold the side button until you see the Power Off slider; Drag the slider to turn off completely; Afterwards, press and hold the side button until you see the Apple logo).

For a more thorough reset and refresh, you could also unpair and re-pair your Apple Watch. Do this via the Apple Watch app on your iPhone, which takes backups of your watch automatically including a fresh one when you unpair via the app. Use the Apple Watch app on your iPhone and choose to Restore from backup when setting up again (this will retain most data and settings):

HI

I have the exact same issue before ios9 after a full day with multiple workouts i was never below 30%. Even with exchsnge syn etc ongoing! And today the first day with ios 9 i hafto charge it before i go to bed with only 3% left

something have changed and i just hope that it gets solved in watchos2 otherwise i will return the watch

Try the steps that I outlined above - they have worked for others.

Thank you for the suggestions!

I am hoping to not have to comb through my Exchange account for issues, as they were not issues moments before this upgrade. However, I will wait until I can recharge my watch and test further through resets of each device, network, etc. and other efforts...and ultimately hope that Apple releases a fix to address this soon.

...Perhaps the battery issue they discovered with WatchOS2 is actually more to do with iOS9?

Hi everybody, i have the same issue! After upgrading to iOS 9 my apple watch battery life is decreasing significantly. Before the upgrading it was lasting all the day without any problem even if I was doing an hour of work out, and I'm not using any exchange calendar, and as it was stated before this is an apple problem!

I just cancelled the new widget for the battery life on IOS9 and see if it would help, I'll let you know.

ciao

Nothing cahnged, apple watch battery life is still decreasing fast! 😟 😟

Where there have been battery issues after the IOS 9 upgrade and the other suggestions haven't helped, the following has worked:

1. Unpair theWatch from the phone. This makes sure your Watch data is backed up on the phone

2. Back up the phone to iTunes (there have been some reported issues with IOS9 and iCloud backups). If you keep Health or Activity data, encrypot the iTunes backup

3. Restore the phone fom iTunes and re-pair the Watch

I noticed the same thing. One new thing that could cause it is the battery monitor in the notification center. I just turned it off as an experiment. I'll let everyone know tomorrow.
