    I ordered the Motorola Turbo charger (ASM15WCHGR-EU3A) done some tests from fully depleted and I don't see any difference compared to a standard HIGH amp charger eg; Nvidia Shield 'SPA011AU5W2' with an output of 5.2V=2.1A

    Both charge around 1% battery for every minute.. 30%=30mins and 100% charge takes around 2 hours on both chargers

    I paid 25 pound and my parents brought it over from the UK to CZ and they go back tomorrow, unless I'm missing something, I'm probably going to send it back for a refund? Anybody else tried 'quick charge 2.0' what 'charge > time' is to be expected?

    I think quick charging needs to be specifically supported by the device and I haven't seen anything about this in 930's specification.
    On the other hand, I believe this is really not healthy for the battery.

    Also please read the spec. It is a dedicated quick charger 2 for moto devices only.
    "All" others get the "standard" 1.5-1.6 mAmp.

    3Only applies to optimized Motorola devices with Qualcomm Quick Charge™ 2.0 technology such as the new Moto X. Battery must be substantially depleted; charging rate slows as charging progresses. All battery life claims are approximate and based on an average mixed use profile that includes both usage and standby time. Actual battery performance will vary and depends on many factors including signal strength, network configuration, age of battery, operating temperature, features selected, device settings, and voice, data, and other application usage patterns.

    Furthermore i also do not believe that any windows phone supports the quick charge 2 standard.
    So in short it's just a "standard" charger for the 930 (but it will not "damage" your batter) and I would advice you to send it back.

    Thanks for the replies,

    Was under the impression 'Quick Charge 2.0' is a standard and certified by Qualcomm, I hope the quote is just the correct context for Motorola website talking about Motorola Products. The key bit I believe is the device needs to have it enabled not just have a Snapdragon 800 inside. I'd looked around and 'forums' including here and it was mentioned it might have been enabled on some phones with "8.1 GDR".

    Decided to keep it as Amazon would charge me some postage to return it. I'll loan it to a colleague at work who has a 'Moto X' and see how it should work, I'll also see if it's 'locked down' by testing on a friends "Note 4" which supports 'QC 2.0'.

    I'll just have to wait to see if a Firmware update and/or 'Windows 10' enables it on the 930, if not my mates a lucky chappy :)

    Indeed it has to be enabled.
    But in the https://www.qualcomm.com/products/sn...n/quick-charge website Windows (NOKIA) is not listed. So lets hope they enable it in w10.
    Now I do not know about this charger but some quick charger 2 have a led which indicates if it is charging "quick" or "slow". Maybe you find this in the manual or check it if you charge your phone and your friends phone.

    In addition, certain battery assemblies have a circuitry that regulate the rate of charging (and discharging)... preventing high rates of discharging and charging. If the battery is designed, for example, to be charged no faster than 1.6A at 5V, then using a 2.0A 5V charger will have the same rate of charging as the 1.6A 5V charger. The only difference is that by using the 2.0A 5V charger often you could be overloading the circuitry and potentially burn it over time.

    This circuit usually is contained in the battery assembly, but it may also be double-regulated by the phone firmware/hardware configuration. If the one in the battery allows 2.0A but the phone only allows 1.6A, then 1.6A will be the limit... but if a future update makes the phone allow 2.0A, then 2.0A will be the new limit.
