10 hours to recharge 75%? This can't be normal can it? topic

I've had this N9 LTE for about a week and a half, so i'm still not used to it fully, but this, this can't be normal right? I havn't seen a device take 10 hours to recharge 75% since the first iPhone in 2007. Plus I have ElementalX Kernal with fast recharge enabled...I don't get it
