I just purchased an LG v10 yesterday, new, from Verizon and I'm wondering if the charge is unusually slow and there may be some manufacturing issue or if I just have too high of expectations? Using the Quick Charge, my phone claims to take about 2 hours and thirty minutes to charge from around 10%. Using the same Quick Charge cable but plugged into my desktop, my phone says it will take 5 hours and some minutes to charge. Is this unusually slow? This is my first time using an Android device. Really appreciate any answers or suggestions, thank you!
