If your phone battery isn't charging or is losing charge when plugged in to your vehicle, try the following solutions.
SWITCH TO A SOCKET CAR CHARGER
Many car USB ports only provide a small amount of power. Most newer phones support one or more fast charging technologies such as "Quick Charge 3.0" and are best paired with a power socket car charger (also called a cigarette lighter charger) that supports the same fast charging technology as your phone.
We recommend searching online for a fast car charger designed for your specific phone model and selecting one with good reviews.
REDUCE SCREEN BRIGHTNESS
The brighter your screen, the more battery power your phone uses. Try dimming the screen brightness, as long as you can still clearly see your phone when using the Driver app.
GET A NEW CABLE
If the solutions above didn't help your phone charge, you may need to buy a new charging cable. We recommend getting one that is braided and has thicker wiring.
USE A PORTABLE POWER BANK
A portable power bank allows you to charge your phone when you're away from your vehicle, so it's charged when you need it.
REMOVE ANY USB ADAPTERS
Any type of adapter to make a charging cable fit your phone can slow down charging. For example, a micro USB cord with a USB-C adapter may charge slower (especially if it's a cheap adapter) than a USB-C cord.
CHECK YOUR CHARGING CABLE
Not all USB port charging cables work the same. Even "fast charging" cables vary by manufacturer in how quickly they charge different devices, meaning some fast charging cables won't work as well as others.
To ensure you're getting the fastest charge possible, we recommend buying a fast charging cable either from or designed for your phone's manufacturer.
CLOSE OUT UNUSED APPS
When your phone is charging, some power goes to background tasks and apps your phone is running. Force quit any apps you're not using to help your phone charge faster.
