Blaze battery life not holding as it should

[SunsetRunner]

I've had the Blaze Fitbit since December. Had great battery life,  it could last up to 4 days. Now it barely keeps the charge through out the day.   Won't even last at night while I'm sleeping.  What's up?

Hi there @SunsetRunner, it's nice to have new faces around the Fitbit Community! Battery use is affected by various factors and settings:

• Make sure you're charging Blaze fully each time. When you think Blaze is done charging, take it out of the charging cradle and then put it back in briefly. If you see a large, blue battery icon you'll know the battery is full.
• If you use the Fitbit app, make sure All-Day Sync is turned off. All-Day Sync increases battery drain on both your tracker and mobile device. To find the setting, open the app and tap or click the Account icon>At the top of the screen tap or click Blaze to see your settings, then scroll down. 
• (Android only) Turn off the Always Connected setting. Similar to All-Day Sync, it can reduce battery life.
• If you don't need heart rate data, change the Heart Rate setting to Off. When you turn it back on, use Auto. 
• Turn call, text, or calendar notifications off if you know you're going to receive many hundreds of notifications. A large volume reduces battery life.
• Charge your tracker more often if you use music control frequently.
• Charge your tracker more often if you do FitStar workouts frequently.
• Turn off Quick View. Since it causes the screen to light up when you turn your wrist towards you, turning this setting off may prolong battery life. To find the setting, open the app and tap or click the Account iconAt the top of the screen tap or click Blaze and then scroll down.
• 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.
• Don't use the maximum Brightness setting.
• 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. 
• Don't charge your tracker in extreme heat or cold.
• Shut down Blaze when it's not in use.
