iPhone 7于2016年发布，配备了一块1960mAh的锂离子电池。该电池设计用于在正常使用条件下提供长达14小时的通话时间和多达13小时的互联网使用时间。然而，随着时间的推移，电池的容量会逐渐降低，导致使用时间缩短。

Apple recently announced that it was intentionally slowing down older iPhone models in order to preserve battery life. This had been a long-standing conspiracy theory floating around the internet.
