A warm welcome to the Community @Sharibc. If your Alta is not holding a charge, I recommend following these tips:
Consider these tips when you want to conserve battery life:
- 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 Account. At the top of the screen tap Alta to see your settings. All-Day Sync is near the bottom.
- Turn off the Always Connected setting. Similar to All-Day Sync, it can reduce battery life.
- Turn off Quick View. Since this feature causes the screen to light up when you turn your wrist towards you, turning it off can prolong battery life. To find the setting, open the app and tap Account. At the top of the screen tap Alta and 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.
- 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.

Catch you later.
