Hi, I typically charge my phone at work using a USB Lightning cable plugged directly into the front of my desktop computer. I usually don't charge it much elsewhere, as it holds enough juice until the next day, although on the weekends will sometimes use the wall charger. Is there anything wrong with using USB/desktop connection as your primary charge source? I just got the iPhone SE and haven't charged it by a wall charger yet, only USB. Is there anything to worry about when charging this way? I see mixed insight here: https://www.quora.com/Should-I-charge-my-phone-by-computer-using-a-USB-or-directly-to-the-wall Let me know your thoughts. I've also read somewhere that the FIRST charge should be via a wall charger, why...I have no idea. Let me know if anyone knows.
