Your Bluetooth and Wi-Fi radios are always searching for new devices and networks, even when they aren’t being used. That said, both can have an impact on your device’s battery life, and a new free jailbreak tweak called AutoBlue by iOS developer Karimo299 attempts to help you find that ideal sweet spot in between performance and battery savings.
AutoBlue works by automatically disabling Bluetooth and/or Wi-Fi after a certain amount of time of being unused. The timers are fully configurable by the end user, and you can even configure the triggers that will re-enable Bluetooth and/or Wi-Fi whenever they become disabled by the tweak.
