Assuming your car does support charging in accessory mode, you might wonder about the charging duration.

Several factors come into play here. The most significant factor is your phone’s battery capacity.

A larger battery will require more time to charge fully. Additionally, the charging speed, determined by the vehicle’s charging capabilities, affects the duration as well.

Some vehicles may offer fast charging, while others provide slower charging speeds.

Now, let’s address the burning question: how long should you charge your phone in accessory mode?

As a general estimate, it usually takes between 1 to 3 hours to charge a smartphone from 0% to 100% in accessory mode depending on the phone battery capacity.

However, keep in mind that accessory mode may affect the charging speed slightly, and different phones have different charging capabilities.


Alternatives to Accessory Mode Charging

If charging your phone in accessory mode is not feasible or supported, fret not! There are other options available.

You can invest in a car charger that connects directly to your vehicle’s power outlet.

These chargers come in various configurations, including USB ports or dedicated charging cables.

Tips for Efficient Charging:

To make the most out of your charging sessions, here are a few tips to keep in mind.

Firstly, ensure you are using a high-quality charging cable that supports fast charging if available.

Secondly, avoid using your phone excessively while it’s charging, as it may slow down the charging process.

Additionally, try to keep your phone’s screen turned off during charging to minimize power consumption.

Lastly, always handle your phone and charger with care and follow safety precautions to prevent any mishaps.

Common Misconceptions:

There are several myths surrounding charging in accessory mode.

Let’s debunk a few of them. Contrary to popular belief, charging your phone in accessory mode does not necessarily make it charge faster.

The charging speed is primarily determined by the vehicle’s charging capabilities and your phone’s compatibility.

Furthermore, using your phone while it’s charging in accessory mode may not drain the car battery significantly, as the charging process is typically designed to draw power from the vehicle’s electrical system.

Best Practices for Charging:

To ensure optimal charging and prolong your phone’s battery lifespan, it’s essential to follow a few best practices.

Do not let your phone’s battery drain completely before charging, as frequent deep discharges can shorten its overall capacity.

Avoid exposing your phone to extreme temperatures, as it can affect battery performance.

It’s also advisable to periodically clean the charging port to remove any dust or debris that may hinder charging efficiency.

Extended Use of Accessory Mode:

While accessory mode can be convenient, it’s crucial to be mindful of its impact on your phone’s battery and overall device performance.

Extended periods of accessory mode usage can strain the battery and increase the heat generated by the device.

Excessive heat can degrade the battery over time and may lead to reduced battery life.

Therefore, it’s recommended to limit the use of accessory mode to necessary tasks and disconnect your phone when not in use to prevent unnecessary drain on the battery.


In conclusion, charging your phone in accessory mode can be a convenient way to keep your device powered on the go.

However, the feasibility and charging duration may vary depending on your vehicle’s specifications.

It is recommended to charge your phone fully before starting your journey and explore alternative charging options if necessary.

By following best practices and considering the factors that affect charging duration, you can ensure optimal charging efficiency and prolong your phone’s battery lifespan.
