    When charging my new 640 with the supplied 110 wall charger, I'm only seeing a charging rate of around 10-12% per hour using information supplied from Arthur Semenov's Battery App. Was just curious as what other L640 owners have noticed with their phones?

    With my old L520, it would usually charge at a little more than 30% per hour. I'm thinking that this higher rate was due to the smaller battery in the 520?

    The 640 has a bigger battery, so the charging time has to go with the battery. Check out this thread: http://forums.windowscentral.com/ask...5-3-hours.html

    I use the original Microsoft AC-20E charger (Input: 100-240V / 50-60Hz, Output: 5.0V / 750mA).
    Official Nokia AC 20E EU MicroUSB Mains Charger | eBay

    My mains voltage is 230 V and the charging rate is about 33 % per hour. Charging from zero to full charge it takes a bit more than three hours.

    Using the 750ma charger that came with my phone, I am seeing varying charging rates from only 10% up to 30% at times. Is this normal charging behavior for a 640?
