Battery life after only one NIGHT

[Deadeye1212]

My battery was fully charged and I put it on at 1 am this morning..  I woke up at 8am and the battery is showing as medium already?  This can't be right surly?

Medium can be a broad description. What's the battery percentage on your versa? (swipe up from the main clock screen)

So I charged it again yesterday JUST before sleeping it was 100%.

I went to sleep at 2.33 and woke up at 10.15.   Its now at 34%

[SteveH]

ok, that's definitely not normal.

The versa is rated at 4+ days from a full charge so that means it loses around 1% per hour. Yours should be around 92% after sleeping rather than the 34%.

Some things can extend battery life e.g. turning off all day sync and fitbit offer this advice:

"The Fitbit Versa battery can last up to 4+ days. Because battery life is affected by use and other settings, actual results may vary.

Consider these tips when you want to conserve battery life:

• Make sure you're charging Versa fully each time. It can take up to 2 hours to charge your watch. For instructions, see How do I charge my Fitbit device?
• Turn off the option to wake the screen when you turn your wrist; instead, tap the screen to turn it on:
  • On your watch, press and hold the back button, then swipe to the quick settings screen > Screen Wake > Manual.
• If you don't need heart rate data, change the Heart Rate setting to Off. Note that the green LED continues to flash even if Heart Rate is turned off.
• Turn off call, text, calendar, and app notifications if you know you're going to receive many hundreds of notifications. A large volume reduces battery life:
  • On your watch, press and hold the back button, then swipe to the quick settings screen > Notifications > Off.
• Charge your watch more often if:
  • You play music or use the music controls frequently
  • You use apps that keep the watch's screen on or frequently access the internet
  • You use an interactive or animated clock face
• Don't receive reminders to move every hour. To get fewer reminders, make sure you walk 250 steps each hour, change the number of hours you want your stationary time monitored, or turn off the feature on days you don't need it.
• If you have many silent alarms set, consider deleting some. Each alarm you add up to the maximum of 8 reduces battery life by a small percentage. 
• Shut down Versa when it's not in use. For instructions, see How do I turn off my Fitbit device?"

But, frankly, yours is so off normal that it sounds like you have a defective battery. My suggestion would be to contact customer support. They can check the stats from the server side and, if they can't fix it, then they can help with warranty replacements. You can get them via: contact.fitbit.com
