an interesting phenomenon i've notice over the last few months is that if i charge my phone using the car charger it tends to last longer than if i charge it off mains power (usually 9 days versus a week with similar usage).

has anyone else noticed this? (and does anyone know why?)

Car battery provide much more current compare with household power supply. But you have to watch out when you charge your handphone when you are using your car charger, don't over charge it, might explode or leak, this usually happen when you travel for a long distance.

i accept that, but wouldn't the battery still only charge to its capacity. surely just because it's a higher current it doesn't mean the battery can hold any more potential (or am i completely off base?)

how come when i bought my car charger, there was a little sticker that said to make sure to unplug it before i started up my car. What is the reasoning for this, and is it really a problem on newer cars?

when you start your car the starter-motor drains current from the battery to get the engine going. once the main engine starts it begins charging the car battery through the alternator. this means that for a second or so after you start the car there is a risk of a current surge from the battery through the charger to your phone, which could damage or destroy the phone/phone battery.

your phone requires a DC current to run and to charge the battery since it is not equiped to deal with an AC current (your socket charger contains a transformer and a few other electronic odds and sods to convert the AC mains power to DC current). normally the car battery is a suitable source of DC electricity, but while starting your car the current can vary (and the car charger can't deal with that).

it's really a pretty small risk, especially for newer cars, but it's to cover the manufacturer's ass if you stuff up. i generally don't plug in until after my car is running.

so all in all, lets play it safe and keep my un-insured phone free from any extra possibility of blowing up.
thanks for the info
