Apple states iPhone 8/8 Plus and X addresses battery issues via hardware


By

Apple formally responded to a congressional inquiry over the controversy with an iOS update addressing degrading battery life. When the battery severely degrades, it may perform unpredictably. The iPhone is designed to protect against low voltage and will shut down if needed. The update essentially throttles the processor performance to conserve battery power in specific situations.

Addressing the question of whether intends to roll out throttling changes to new models, Apple indicated that it may have mitigated the issue with hardware changes in the iPhone 8/8 Plus and iPhone X:

"iPhone 8, iPhone 8 Plus, and iPhone X models include hardware updates that allow a more advanced performance management system that more precisely allows iOS to anticipate and avoid an unexpected shutdown.
