The myths and facts behind charging your cellphone using the conventional charger are never-ending. Some theories speak about temperate changes, which is justified. Freezing and heating phones can determine how long a discharge could take. However, some more concrete news from Battery University has us believing that Lithium-ion batteries last longer when charged ‘the slow way’. This preferably hints at computer USB charging as against the charger replenishment. It’s a useful insight and easily implementable by those who are before a PC all day. The study also states, ‘Elevated temperature hastens capacity loss. The capacity cannot be restored. Not all Li-ion systems behave the same’. So that questions your geography as well.
