Low power mode
First Claim
1. A method of an electronic device including a display and a battery, the method comprising:
- obtaining a first characteristic of the battery;
determining whether 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;
after enabling the 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, equal to or higher than the first 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 storing authorization information for performing one or more transactions that require the authorization information; 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,wherein;
in the high power mode, the electronic device is configured to perform a first set of functions, including performing the one or more transactions, andin the low power mode, the electronic device is configured to perform only a second set of functions, a subset of the first set of functions and including fewer functions than the first set of functions, including performing the one or more transactions using the stored authorization information.

Abstract
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.
