How can I save battery on my Sky Smart Doorbell?

If your Sky Smart Doorbell battery seems to be running down faster than expected, you’re not alone and there are a few simple things you can do to help it last longer.

In the best‑case scenario, a Smart Doorbell battery can last up to 90 days. However, real‑world battery life depends on how it’s used. Things like how often it records, clip length, night‑time activity and motion detection settings can all make a big difference.

Here are some easy ways to reduce unnecessary battery drain and get the most out of your Smart Doorbell.

Step 1: Check your signal strength

A weak signal can cause your Smart Doorbell to use more power as it works harder to stay connected.

You can quickly check the signal strength in the Sky Smart Home app:

Here’s how to run a signal test:

Open the Sky Smart Home App
Go to Settings
Under Device Settings, select Devices
Tap Smart Doorbell
Under Technical Information, select Signal
Tap Run Test

For the best performance, aim for a Good signal (3 bars or more).

If the signal is weak, try:

Moving the Chime closer to the doorbell
Reducing obstacles between the doorbell and the Chime

Step 2: Adjust your clip recording settings

If your signal is already good, tweaking your recording settings can have a big impact on battery life — especially if your doorbell faces a busy area.

To change clip length and time between recordings:

Open the Sky Smart Home App
Go to Settings
Select Smart Doorbell Settings
Go to Video Recording Settings

From here, you can adjust:

Clip Recording Length

15 seconds – longest battery life
30 seconds – standard setting
60 seconds – shortest battery life

Time Between Clips

60 seconds – longest battery life
30 seconds – standard setting
15 seconds – shortest battery life

Reducing the default 30‑second clip length can be especially helpful if your doorbell records frequent movement.

Step 3: Reduce unnecessary motion detection

Frequent motion alerts and recordings can quickly drain the battery, even when nothing important is happening.

A few small changes can help:

Set up an Activity Zone so recordings only focus on areas that matter
Use the wedges provided to angle the Smart Doorbell away from busy streets or pavements

To set up an Activity Zone:

Open your Smart Doorbell live feed
Tap the Settings icon
Under Smart Doorbell Settings, select Person Detection Settings
Select Activity Zones
Toggle Activity Zone to On
Adjust the zone to suit your space

Extra tips to help your battery last longer

A few additional things can also make a difference:

Turn off Person Detection if you don’t need it
Avoid positioning your Smart Doorbell near:
- Thick walls or foil‑backed insulation
- Metal or fire doors
- Large appliances like fridges or freezers
Keep the distance between your Smart Doorbell and Chime as short as possible
