Question: How to replace or charge the battery in a Xiaomi smart doorbell?
Answer:
Xiaomi smart doorbells, particularly popular models like the Xiaomi Smart Doorbell 3 and Xiaomi Smart Doorbell 3S, use a built-in rechargeable lithium battery (typically 5200mAh capacity). These batteries are not user-replaceable — the design emphasizes long battery life (up to 4-5 months per charge, depending on usage) to avoid the need for frequent charging or replacement.
How to Charge the Battery:
- Disable the removal alarm (if enabled) in the Mi Home/Xiaomi Home app to prevent false alerts.
- Use the provided removal pin (included in the box) — insert it into the small pinhole at the top of the doorbell and press firmly.
- Push the doorbell upward to slide it off the mounting base.
- Locate the USB Type-C charging port (usually at the bottom of the doorbell).
- Connect a USB Type-C cable (the one provided or any compatible cable) to the port and plug it into a power adapter.
- Recommended: A safety-certified 5V/2A adapter for optimal charging (full charge in about 3-5 hours).
- You can use a lower-current adapter (e.g., 5V/1A), but it will take longer.
- The doorbell button light will show a breathing white light while charging and turn solid white when fully charged.
- Once charged, slide the doorbell back onto the mounting base until it clicks into place (it powers on automatically).
Notes:
- Battery life varies based on usage (e.g., motion detection frequency, video recordings, Wi-Fi signal strength, temperature).
- Some models (e.g., Doorbell 3S) support optional hardwired power (8-24V AC) for continuous operation without relying on the battery.
- Check battery level in the Mi Home/Xiaomi Home app — it may not update in real-time; press the doorbell button or trigger motion to sync the status.
- If the battery no longer holds a charge after years of use, contact Xiaomi support, as the battery is integrated and not meant for user replacement.
