Car phone charger battery drain.

When a battery gets old and you are online with the screen on the battery will slowly lose charge becaus. It s hard to say at this moment in time as there are many reasons as to why this may be happening.

Many of the newer car s trucks cig lighters accessory jacks now power off with the ignition switch to prevent this.

However there are other actors that come into play like your charging port and actual device software. Avoid car battery drainage. A car battery holds around 800 watt hours of power.

It s plugged into a live outlet 24 7.
