Wireless charging isn't exactly new but very few, like Samsung, make it a must-have for their flagship products. Things might soon change, however, if the iPhone 8 does end up having such a feature. LG is also jumping on board with its upcoming flagship. The LG V30, which may break cover as early as August, is now tipped to switch to a glass back in order to support wireless charging. While that does seem like good news, it could raise some questions as well.
