Apple Inc said it will provide a free battery replacement¹ for customers globally who have experienced an unexpected shutdown with their iPhone 6s smartphones.

苹果公司日前表示，将为全球各地遭遇iPhone 6s智能手机意外关机的消费者免费更换电池。

Apple has determined² that a very small number of iPhone 6s devices may unexpectedly shut down, the company said in a statement.

苹果在一份声明中表示，该公司已确认有极少数的iPhone 6s设备可能会意外关机。

This isn't a safety issue and only affects devices within a limited serial³ number range that were manufactured in September and October 2015, Apple said.

该公司称，这并非一个安全问题且仅会影响序列号在一定范围内、在2015年9月到10月期间生产的设备。

The battery life of both iPhone 6s and 6s Plus have reportedly been questioned by consumers after they complained how their phones would shut down even when the battery showed a significant amount of power.

据报道， iPhone 6s和6s Plus的电池寿命均受到了消费者的质疑。此前有消费者投诉称，即使在电池显示电量充足的情况下，手机仍会关机。

Apple said customers experiencing the problem can visit an Apple retail⁴ store or authorized⁵ service provider to verify that their device was manufactured during the covered period.

苹果方面表示，遭遇这一问题的消费者可前往苹果零售店或苹果授权服务提供商，核实其设备是否是在上述期限内生产的。

Customers who previously⁶ paid to have their batteries replaced for this issue can contact Apple to request refunds⁷.

此前因该问题已付费更换电池的消费者可联系苹果要求退款。

The iPhone 6s was released last year but is still being sold. Apple released its latest version, the iPhone 7, this fall.

iPhone 6s手机于去年发布，现在仍在热销。苹果公司于今年秋天发布了最新机型iPhone 7。
