    I've experienced that that charging my iphone 4s with an ipad charger (10w) it charges quicker than charging it with the 5w the iphone comes with
    is it normal? and does this cause a stress to the battery?

    what is the maximum watt the iphone can handle? and why they only give you a 5w when the 10w it's much faster?

    I assume that charging with 10w WILL WORK but a slow charge is healthier that a fast charge! so they put a 5w charger to preserve battery life..

    Size trumps over charging speed.

    Is possible.

    Not sure, but the iPhone will not take more power than it can accept. So, fi you plug in an Apple 12W charger and the iPhone can at max take only 10, the power supply will only deliver 10.


    Because as you've noticed the 10W/12W charger is bulkier than the 5W charger. More than likely, 10/12W units are also more expensive to build.

    When users prefer smaller, less bulky chargers, they fit nicer in the packaging, and Apple can include them at lower cost, it makes sense for them to make the 5W units and include them with the phones.

    There was a site that looked into it. It was around 7.5w.

    But the 5w charger is the perfect size and weight. Cost is also a factor ;)

    ok so I immagine that chargin the iphone with a 10w charger, the iphone only will get 7,5w form it, since getting it to charge faster than the 5w standard one. it's good to know that in emergency situation you can charge your phone 50% faster;)

    MONEY! The 5W charger is much cheaper and fits in the iPhone box.

    95% of iPhone users plug their phone into the charger before they go to bed and it does not matter how long it takes to charge. I usually have 50-60% left at the end of the day and the 5W charger brings it to 100% quickly.
