I just started charging my LG V10, but when I looked at the charging screen, it looked different:
The three dot menu had one dropdown for Boost Charge, but there was nothing to change there. Also, the time to charge was much higher than normal, like my Fast Charge function wasn't working. Later on it also added ads, which I despise.
I figured it out. It's a new feature of the TouchPal keyboard app. Open the app, hit the hamburger menu, select Settings. Select General Settings and scroll to the bottom where you'll see Boost Charge. Tap it and you'll get another screen where you can change the Boost Charge setting. If you uncheck it, it will disable the Boost Charge function and restore your old charge screen (and your old charging algorithm).
