The good news? Replacing the battery is simple, safe, and takes less than 15 minutes. Whether you’re a tech-savvy homeowner or a beginner, this guide will walk you through the entire process—from preparing your tools to reattaching the doorbell and ensuring it works perfectly. By the end, you’ll know exactly how to change the battery in your Wyze Doorbell and keep it running smoothly for months to come.

Before you begin, gather the following items to ensure a hassle-free battery replacement:

Wyze Doorbell battery: Make sure you have a fully charged replacement battery. Wyze sells official replacement batteries on their website or through authorized retailers. Using a genuine Wyze battery ensures compatibility and safety.
Small Phillips-head screwdriver: Most Wyze Doorbells use a small screw to secure the faceplate. A #0 or #1 Phillips screwdriver works best.
Clean, dry cloth: Use this to wipe down the doorbell and remove dust or debris before reassembly.

Optional: Step ladder: If your doorbell is mounted high, a stable ladder will help you reach it safely.

Having these tools ready will save time and prevent frustration during the process.

Step 1: Turn Off Power at the Circuit Breaker

Even though the Wyze Doorbell is battery-powered, it’s always a smart idea to turn off the power at the circuit breaker before handling any electronic device near wiring. This is especially important if your doorbell is connected to existing doorbell wires (even if it’s running on battery).

Why This Step Matters

Turning off the power prevents accidental short circuits or electrical shocks. While the risk is low, safety should always come first.

How to Do It

Locate your home’s main electrical panel (usually in the basement, garage, or utility closet).
Find the breaker labeled “Doorbell,” “Front Door,” or something similar. If you’re unsure, turn off the main breaker to be safe.
Flip the switch to the “Off” position.
Test the doorbell by pressing the button—if it doesn’t light up or chime, the power is off.

Once the power is off, you can safely proceed to remove the doorbell.

Step 2: Remove the Wyze Doorbell from the Mounting Plate

Now that the power is off, it’s time to take the doorbell off the wall. The Wyze Doorbell attaches to a mounting plate with a secure snap-on design, but it’s held in place by a small security screw to prevent theft.

Locate the Security Screw

Look at the bottom edge of the doorbell. You’ll see a tiny screw head—this is the security screw. It’s designed to prevent unauthorized removal, so you’ll need your Phillips-head screwdriver to loosen it.

Unscrew and Detach

Insert the screwdriver into the security screw and turn it counterclockwise until it’s loose. Don’t remove it completely—just loosen it enough to release the doorbell.
Gently pull the bottom of the doorbell away from the wall. It should pop off the mounting plate with a slight tug.
Lift the doorbell straight up to fully detach it from the plate.

Be careful not to drop the doorbell. If it’s high up, have someone assist you or use a ladder with a non-slip base.

Step 3: Open the Battery Compartment

With the doorbell in your hands, you’re ready to access the battery. The battery compartment is located on the back of the device, behind a protective cover.

Find the Battery Cover

Flip the doorbell over. You’ll see a rectangular cover held in place by two small screws. These screws are usually silver or black and are smaller than the security screw.

Remove the Cover Screws

Use your Phillips-head screwdriver to carefully unscrew both screws.
Set the screws aside in a small container or on a piece of tape so they don’t get lost.
Gently lift off the battery cover. It should come off easily—no force needed.

Locate the Battery

Inside, you’ll see the rechargeable lithium-ion battery. It’s a flat, rectangular module with two wires connected to a small plug. The battery is labeled with the Wyze logo and model number (usually WYZE-DB-BAT).

Step 4: Disconnect the Old Battery

Now it’s time to remove the old battery. Handle this step with care to avoid damaging the internal components.

Unplug the Battery Connector

Locate the small white or black plug that connects the battery to the doorbell’s circuit board.
Gently pull the plug straight out. Do not yank or twist it—this could damage the wires or connector.
If the plug is tight, use your fingernails or a plastic spudger (a non-conductive tool) to carefully pry it loose.

Remove the Battery

Once the plug is disconnected, the battery should slide out easily. If it’s stuck, gently wiggle it side to side while pulling upward.

Handle with Care

Lithium-ion batteries can be hazardous if punctured, crushed, or exposed to heat. Avoid touching the metal contacts, and do not attempt to open or modify the battery.

Step 5: Insert the New Battery

With the old battery removed, it’s time to install the new one. Make sure the replacement battery is fully charged before installation.

Check Battery Orientation

Look at the old battery and note how it was positioned. The new battery should go in the same way—usually with the label facing up and the connector on the same side.

Slide in the New Battery

Align the new battery with the compartment slot.
Gently slide it into place until it sits flush.
Ensure it’s secure and doesn’t wobble.

Reconnect the Battery Plug

Take the connector from the new battery and align it with the port on the circuit board.
Push it in firmly until it clicks into place. You should feel a slight snap when it’s properly connected.
Double-check that the connection is secure—loose plugs can cause power issues.

Step 6: Reattach the Battery Cover

Now that the new battery is installed, it’s time to close up the doorbell.

Replace the Cover

Position the battery cover over the compartment.
Align the screw holes on the cover with those on the doorbell.
Insert the two small screws and tighten them with your screwdriver. Don’t overtighten—this could strip the screws or crack the plastic.

Test the Cover

Give the cover a gentle tug to make sure it’s secure. If it moves, tighten the screws a little more.

Step 7: Reattach the Doorbell to the Mounting Plate

With the battery replaced and the cover secured, it’s time to put the doorbell back on the wall.

Align the Doorbell

Hold the doorbell with the camera lens facing outward.
Position the top of the doorbell over the mounting plate’s upper hooks.
Slide it down slightly until it clicks into place.

Secure with the Security Screw

Press the bottom of the doorbell against the wall until it snaps in.
Use your screwdriver to tighten the security screw at the bottom. Turn it clockwise until snug.
Do not overtighten—this could damage the screw or the doorbell housing.

Step 8: Turn Power Back On and Test the Doorbell

Now that the doorbell is back in place, restore power and test it.

Restore Power

Go back to your electrical panel.
Flip the doorbell breaker (or main breaker) back to the “On” position.

Check the Doorbell

Wait 30–60 seconds for the doorbell to power up.
Look for the status light—usually a solid blue or green light indicates it’s connected.
Open the Wyze app on your phone and check the device status.

Test the Button

Press the doorbell button. You should hear a chime (if connected to a chime kit) and receive a notification on your phone. If the doorbell doesn’t respond, proceed to the troubleshooting section below.

Step 9: Re-Pair the Doorbell (If Needed)

Sometimes, after a battery change, the doorbell may lose its connection to the Wi-Fi network or the Wyze app. If this happens, you’ll need to re-pair it.

Check Connection in the App

Open the Wyze app and go to the device list. If your doorbell shows as “offline” or “disconnected,” follow these steps:

Re-Pairing Steps

In the Wyze app, tap the “+” icon and select “Add Device.”
Choose “Doorbell” and follow the on-screen instructions.
When prompted, press and hold the setup button on the back of the doorbell (usually for 3–5 seconds) until the light flashes yellow.
The app will search for the device and connect it to your Wi-Fi network.
Once connected, test the doorbell again.

Re-pairing usually takes 2–3 minutes and restores full functionality.

Troubleshooting Common Issues

Even with careful installation, you might run into a few hiccups. Here’s how to fix the most common problems:

Doorbell Won’t Power On

Check the battery connection: Make sure the plug is fully inserted and the battery is seated properly.
Verify the battery is charged: Use a known-good battery or charge the new one fully before installation.
Inspect for damage: Look for cracks, swelling, or corrosion on the battery or connectors.

No Notification When Button Is Pressed

Check Wi-Fi signal: Weak Wi-Fi can delay notifications. Move your router closer or use a Wi-Fi extender.
Verify app settings: Ensure notifications are enabled in the Wyze app under Device Settings > Notifications.
Test the chime: If using a mechanical chime, make sure it’s compatible and properly wired.

Battery Drains Too Fast

Reduce motion sensitivity: High sensitivity causes frequent recordings, draining the battery. Adjust in the app under Motion Detection.
Limit live views: Frequent live streaming uses more power. Use it sparingly.
Update firmware: Wyze regularly releases updates that improve battery efficiency. Check for updates in the app.

Doorbell Falls Off the Wall

Tighten the security screw: A loose screw is the most common cause. Use your screwdriver to secure it.
Check the mounting plate: Ensure the plate is firmly attached to the wall with screws, not just adhesive.
Use anti-theft screws: Wyze sells tamper-resistant screws that require a special tool to remove.

Tips for Maintaining Your Wyze Doorbell Battery

To extend battery life and avoid frequent replacements, follow these best practices:

Charge the battery fully before reinstalling: A full charge ensures maximum runtime.
Store spare batteries properly: Keep them in a cool, dry place away from direct sunlight. Avoid extreme temperatures.
Clean the doorbell regularly: Dust and dirt can block sensors and cameras. Wipe the lens and motion sensor with a soft, dry cloth.
Monitor battery levels in the app: The Wyze app shows battery percentage. Recharge or replace when it drops below 20%.
Avoid frequent live views: Each live stream uses significant power. Use recordings instead when possible.
Enable power-saving modes: Some Wyze models offer low-power modes that reduce activity when not needed.
