Disadvantages of charging your iPhone in the car
Charging your iPhone in the car has some risks and drawbacks, so here are the main ones we'll cover.
May reduce battery life
Car chargers may have less stable voltage and current than home chargers, which can negatively impact your iPhone battery life over long periods of use.
Damage caused by overheating
The temperature inside a car can get very high, especially in the summer. Charging in a hot environment can cause the inside of your iPhone to overheat and damage the battery and other components.
Slow charging speed
Car chargers typically have lower power than home outlets, so charging speeds may be slower, especially if you're charging multiple devices at the same time.
The risk of overcharging the battery
Some car chargers have insufficient overcharging protection. Overcharging puts strain on the battery and can cause a decrease in battery performance in the long term.
How to Safely Charge Your iPhone in the Car
Charging your iPhone in the car does come with risks, but it can be done safely if you follow the right steps. Here are some tips on how to charge safely.
Choose a reliable car charger
First, use a reliable car charger that has overcharging protection and current stability. Using certified products can minimize damage to your iPhone.

Avoid fast charging
Fast charging puts a strain on the battery so it is best to avoid it as much as possible. Maintaining a normal charging speed will help preserve the battery life.
Pay attention to the temperature inside the car
Avoid charging when the temperature inside the car is high. It is important to keep the car cool with the air conditioner to prevent the battery from overheating.
Charging while parked
Vibrations and electrical fluctuations while driving may affect charging, so it is recommended that you charge while stationary whenever possible.
Problems that can occur when charging your iPhone in the car and how to fix them
When charging your iPhone in the car, unexpected problems may occur. Here are some common issues and how to solve them.
Forced shutdown due to overheating
Situation: In summer or when the temperature inside a car is high, your iPhone may overheat and shut down automatically.
Solution: First, stop charging and move your iPhone to a cooler place to let it cool down. It is safe to try charging it again after it has cooled down.
Charging is not progressing or is slow
Situation: If your car charger is not powerful enough, your phone may charge slowly or not at all, especially if you are charging other devices at the same time.
Solution: Temporarily unplug other devices to prioritize charging your iPhone. Also, check the condition of the charger itself and consider replacing it if necessary.
Rapid battery drain
Situation: If your battery is draining quickly after charging in the car, this may indicate a charger issue or overcharging.
Solution: First, check your charger and switch to a reliable one. It is also important to check your iPhone settings to see if the battery condition is deteriorating.
Battery runs out when the car engine is turned off
Situation: In some cars, charging may automatically shut off when the engine is turned off.
What to do: If this happens, restart the engine and resume charging, or use a charging port that will continue charging even when the engine is off.
Battery swelling
Situation: If you continue to charge your iPhone in the car for a long time or use a deteriorated charger, there is a risk that the battery will expand. If the battery expands, it may cause the iPhone body to deform or, in the worst case, it may catch fire.
Solution: First, if your battery is swollen, stop using it immediately and take it to an authorized Apple service center for repair. In addition, to reduce the risk of battery swelling, it is important to use a reliable charger and check the battery status of your iPhone regularly.
