0-30mins for 100% battery?!? Are u serious!!! My lg v20 with removable battery will have 100% battery in 1min. I just swap a fresh 100% battery and voila its now full charged. While the battery that i replaced ill just charge it with my wall charger while using my phone with 100% battery and if i ran out again by that time i have a 100% fully charged battery reserved on my wall charger and swap it again. Rinse and repeat so virtually im not running out of battery. Yeah new tech lololol.
