    Does using a wireless charger not charge your phone as well as a corded charging. I have not been getting as good battery life when using a Nokia wireless charger. I just got the nexus orb, so maybe that will work better

    How you charge the phone has nothing to do with how well you charge the phone. If the charger is feeding the right voltage to the phone, it's going to charge. Wires, wireless or black magic make no difference.

    Would the Nokia wireless not have the right about of voltage?

    I have a koolpad wireless charger and i love it.The question i have is, does leaving it plugged in and switched on all day affect the life of the charger itself ?.

    I'm using the Nokia DT-900 with my phone. Works great. Charges fairly fast (obviously not as fast as the wall charger, but not terribly slow either). It takes about an hour to get from about 55-60% to 100%.

    Phone's battery life doesn't change depending on how it is charged (wall charger/wireless)

    Thanks for this info. I've been on the fence about which charger to get, but I see AT&T still has this one for $24.99, and there's a store a mile from my house that has them in stock. I'm heading up there this afternoon.

    Oooooooooooooooooh. Heading to my AT&T then to see if they have it. That's cheaper than Amazon. I've been very frustrated trying to find accessories in-store. I just want a coiled micro-usb to usb cord for goodness sake.

    Check the AT&T wireless website. I was able to check in-store quantities when I looked last night.

    I went to the local AT&T store today and picked up this charger. I noticed the website said online special only, but it was 24.50 in the store also.

    The cable from the wall wart to the pad is proprietary - it is not USB. I wanted to post that in case anyone thought they could plug it into their computer.

    The manager spotted my N5 sticking out of my shirt pocket and was on it like white on rice. Asked if he could look at it, where I got it, how I liked it, etc. He had the other store employees come take a look at it. There were a few other customers in the store trying to figure out what all the fuss was about. :)

    And that's one of the reasons I love this phone.

    If you can find other people who also want this, you can get 3 from att.com and get a 25% discount. So, you can get 3 for $55.14 making it just under $18.50 for each

    Not necessarily true.

    Even when charging wired, different methods (USB vs AC adapter) charge at different speeds (rates), dependent on the amperage, despite that the voltage is the same. I'm not sure what kind of max amperage the Nexus 5 can handle, but by way of comparison, your USB port and smaller duty AC adapters push out 0.5 Amps, while the heavy duty ones push 2.0 Amps; the latter charges significantly faster.

    The same can be applied to wireless charging, with the caveat that some of the charging throughput is lost through significant inefficiencies with wireless charging.

    On the original wireless smartphone charger, the Palm Pre and Palm Touchstone, the Touchstone was notoriously fickle, and would not generate a strong enough EM field for the phone to register charging if you hooked up an AC adapter with anything less than 2.0 Amps of current.

    And even then, it charged notably slower than hooking up a 2.0A charger directly to the Palm Pre. It charged roughly as fast as a 0.5A charger hooked directly to the Pre.

    So yes, there is a measurable difference between wired and wireless. That said, neither should affect battery life to the extent that you charge both to 100% capacity; the difference only lies with how fast the battery charges, not any qualitative differences after the battery is charged.

    Thanks for the info. I do notice the wireless one is much slower to charge

    Is it bad for the battery to keep the phone on the wireless charger charging when the phone is only at 50% or so?

    Re: Touchstone stuff

    The first batch of Touchstones had some issues with being finicky (due to a manufacturing issue nothing to do with EM field strength) but otherwise charging rate of the Pre with Touchstone or wired was identical (~700mA, set by Pre electronics not Touchstone) when connected to a 1A or 2A charger.
    First generation Touchstone DC-DC measured efficiency was approx 80% at full load. Later Touchstones (including the Tablet version) was about approx 85% full load eff.

    Best regards-
    MC
    (I designed the Touchstone line).

    Wow, that's fantastically interesting information to have.

    It's been a terribly long time since I had the Pre, but I vaguely recall lots of discussion over which was the fastest way to charge. It's too bad we didn't have any actual designers to chime in... and it's generally why I get frustrated with all the anecdotal discussion over "battery life" and "charging", because as it seems, a lot of changes/differences are imagined. Unfortunately, as consumers we don't have many great ways of objectively testing.

    Anyway, as an old Pre user, thanks for chiming in! It's too bad the platform never took off like it should have.

    As a side note (not that it matters based on your information), I was wrong about the 2A; what I meant was 1A, the output of the barrel shaped Palm Pre charger.
