How to Check Samsung Battery Health with Dialer Code in Canada

Want to quickly check the battery health of your Samsung Galaxy in Canada? While Samsung doesn't provide a built-in battery health percentage like Apple, you can still run an internal hardware test using a hidden dialer code. This method works on Galaxy S25, S24, and A-Series devices used on Canadian carriers such as Rogers, Bell, Telus, Freedom, and Videotron.

What the Dialer Code Does

The Samsung diagnostic code opens a hardware-level test interface known as Samsung Device Diagnostic. It checks components such as the battery, sensors, display, and connectivity without needing any apps.

This method is especially useful in Canada where colder temperatures can affect lithium battery performance.

Dialer Code to Check Battery Health on Samsung (Canada)

On most Canadian Samsung models, the diagnostic code is:

*#*#4636#*#*

If this one does not work on your carrier-branded model, you can also try:

*#0228#

These codes behave differently based on device model, Android version, and carrier restrictions.

How to Use the Code (Step-by-Step)

Step 1: Open the Phone App

Launch the default Phone / Dialer app on your Samsung Galaxy.

Step 2: Enter the Diagnostic Code

Type either *#*#4636#*#* or *#0228# depending on your device. The diagnostic menu should open automatically.

Step 3: Check Battery Information

Depending on the code, you will see one of the following:

• Battery Status — Shows real-time usage
• Battery Level — Current percentage
• Voltage — Indicates battery health trends
• Capacity / mAh (if available on your model)
• Discharging / Charging Speed

Note: Some Canadian carrier variants (especially Rogers and Bell) may limit this menu due to firmware controls.

How to Interpret the Results (For Canadian Users)

1. Battery Voltage

Typical healthy Samsung battery voltage: 4.3V – 4.4V (full charge)

If voltage drops unusually fast in cold weather (common in winter), degradation may be present.

2. Battery Capacity (if shown)

A healthy capacity should be close to the original rated mAh. A difference greater than 15–20% indicates aging.

3. “Quick Start” Test (from *#0228#)

This recalibrates the battery and can help if your device shuts down early or percentage drops suddenly in cold climates like Ontario, Quebec, or Alberta.

Why Battery Degrades Faster in Canada

• Cold temperatures in provinces like Manitoba and Saskatchewan reduce battery efficiency
• 5G connectivity on Rogers/Bell/Telus increases power usage
• Navigation and heat during summer also impact battery wear
• Frequent fast charging during commuting is common in Canada

When to Use the Dialer Code vs Samsung Members

Dialer Code:

• Quick hardware check
• Useful if Samsung Members isn’t showing the “Battery Status” test

Samsung Members (recommended):

• More accurate diagnostics
• Shows “Good / Average / Action Required” status

Tips to Improve Battery Life in Canada

• Avoid charging your phone outdoors in freezing temperatures
• Use Protect Battery to limit charge to 85%
• Turn off 5G in low-coverage rural areas to reduce drain
• Use Samsung-certified fast chargers
• Keep your phone warm inside jacket pockets during winter
