How to Stop Fitbit Charge 4 Battery Draining Fast From 2020

Your Fitbit Charge 4 from 2020 used to last a week on a single charge, but now it barely makes it through a day. This is often due to heavy features or aging hardware.

Why Is Your Fitbit Charge 4 Battery Draining So Fast?

A Fitbit Charge 4 from 2020 with a fast-draining battery might be overloaded by notifications, constant heart rate monitoring, or a worn-out cell. After years of use, battery life naturally declines, but you can stop the drain with these steps.


Tools You’ll Need

  • Fitbit app on your phone
  • Charger cable
  • Microfiber cloth
  • Computer (optional for firmware)

Step 1: Check Battery Usage

Identify power hogs.

  • In the Fitbit app, go to Today > Battery.
  • Note features like GPS or All-Day Sync using the most juice.
  • Disable unnecessary ones (e.g., Weather) via app settings.

Step 2: Adjust Settings

Lower power consumption.

  1. Turn off Always-On Display in Settings > Display.
  2. Reduce brightness or set it to Auto.
  3. Limit heart rate tracking to workouts only if not critical.

Step 3: Update or Roll Back Firmware

Firmware bugs can drain power.

  • Check for updates in Account > Charge 4 > Update.
  • If a recent update caused the issue, downgrade via Fitbit support (older versions available online).
  • Restart after updating.

Step 4: Clean Charging Contacts

Poor charging shortens life.

  • Wipe the Charge 4 contacts and charger pins with a microfiber cloth and rubbing alcohol.
  • Ensure a firm connection—charge to 100% and monitor.

Step 5: Replace the Battery (Advanced)

Old batteries fade.

  1. Contact Fitbit support for a replacement (around $30-$50 if out of warranty).
  2. DIY replacement voids warranty—use a guide if skilled.
  3. Test battery life post-replacement.

Your Charge 4 battery should last longer now. For step tracking issues, see this guide. For Bluetooth sync problems, check this fix.
