How To Extend Your Phone’s Battery Life In This Texas Heat

Like most Texans, I spend a lot of time in my vehicle. Between live broadcasts, station events, and traveling around West Texas, my phone is almost always riding along with me.

But something happened recently that made me stop and think.

My wife Donna had to replace the battery in her iPhone, and the phone wasn't even a year old. However, the replacement cost over $150. Meanwhile, my phone is more than two years old and still working just fine.

That got me wondering about something we all do every day without thinking about it.

We charge our phones in our cars.

Texas Vehicles Produce More Power Than Phones Need

Most vehicles operate on a 12-volt electrical system, and when the engine is running, the alternator usually pushes that closer to 14 volts.

Smartphones typically charge using about 5 volts through a USB connection. That’s why most car chargers contain a small converter that safely reduces the vehicle’s power down to a level your phone can handle.

So technically, charging your phone in your vehicle is generally safe, as long as you're using a quality charger.

The Real Problem May Be Texas Heat

The bigger issue may actually be heat.

Think about what many of us do. We plug our phone in and toss it on the console or passenger seat while the Texas sun pours through the windshield.

Now your phone is:

• charging
• generating heat
• sitting in direct sunlight

That combination can cause the battery temperature to rise quickly, and lithium-ion batteries do not tolerate heat very well. Experts say repeated exposure to high temperatures can shorten battery life significantly.

A Simple Tip That Could Save You Money

If you charge your phone in your vehicle, try to:

1. Keep it out of direct sunlight
2. Use a good quality charger
3. Unplug it once it’s fully charged
4. Avoid charging when the phone is already hot

Your battery and your wallet may thank you later.

And after seeing Donna’s repair bill, I know one thing for sure.

I’ll be paying a lot more attention to where I leave my phone in the truck.
