In December 2017, it became officially known that the performance of the iPhone 6, iPhone 6s, iPhone SE and iPhone 7 decreases as their batteries are depleted or smartphones are in the cold. Replacing the old battery with a new one, thus, allows not only to noticeably increase the battery life of these iPhone models, but also to greatly increase the speed of work.
