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.
- Turn off Always-On Display in Settings > Display.
- Reduce brightness or set it to Auto.
- 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.
- Contact Fitbit support for a replacement (around $30-$50 if out of warranty).
- DIY replacement voids warranty—use a guide if skilled.
- Test battery life post-replacement.
