LOW POWER MODE

摘要

Examples of the disclosure are directed to a method of, after hitting a UVLO threshold, rebooting an electronic device in a low power mode having a lower UVLO threshold, such that the device can continue to be used past the first UVLO threshold. For example, in a high power mode, the device may be capable of a number of functionalities of a modern portable electronic device, such as network access, the ability to run applications, Bluetooth connections, etc. In a low power mode, the device may only be able to check and display a current time, play an alarm sound at a predefined time, perform near field communication (NFC) transactions/payments, among other possibilities described herein. The limited functionality and reduced usage of peripherals in the low power mode may prevent the battery from experiencing peaks in current level that may be problematic at relatively low levels of voltage.

主权项

1. A method of an electronic device including a battery, the method comprising:
obtaining a first characteristic of the battery; determining that the first characteristic is lower than a first threshold; in accordance with a determination that the first characteristic is lower than the first threshold, enabling a low power mode; initiating a booting process; obtaining a second characteristic of the battery; determining whether the second characteristic is lower than a second threshold; in accordance with a determination that the second characteristic is lower than the second threshold, continuing the booting process according to the low power mode; and in accordance with a determination that the second characteristic is higher than the second threshold, continuing the booting process according to a high power mode.
