Charging Lumia in the car - still drains faster than it charges!
I've had my L920 for two years now. I still don't understand why using GPS in the car drains the battery faster than the charger can charge it.
I had been charging the phone using an AC inverter which allowed me to convert the 12v DC power to 230v AC. With that I connected my standard home charger to the inverter. This worked perfectly, it charged the phone quickly and I was able to use GPS on long journey without worrying about getting stranded with a flat battery and no GPS.
Recently the alternator in my car went bad and I replaced it. I decided it was time to stop using the AC inverter because going from DC to AC is very inefficient and I didn't want to put an excessive load on my new alternator.
I researched this heavily because I knew that all the chargers I'd tried in the past didn't cut it.
I bought an Aukey charger which has two 2.4a 5v USB outlets. (far greater than the AC charger). I also bought a PortaPow charging cable.
After using it for a few months, I've reached this conclusion:
The new set up works if brightness is set to low and 4G is disabled. If I start my journey with 100% battery, I will arrive at my destination with 100%; however, if I start a 2 hour journey with 50% battery, I won't have 100% when I arrive.
It charges faster with an AC charger which has a lower current output. Why?
I'm still having to carry the AC charger everywhere I go because charging in the car during my commute is still not viable unless I use the dirty inverter.
