iPhone owners can use the included Low Power Mode to save battery life on their iPhone in a pinch, and while it can be useful, I don’t particularly care for how it forces a 30-second auto-lock down your throat.

Apple doesn’t give you a way to increase the auto-lock timeout on a stock device with Low Power Mode enabled, but jailbreakers can take advantage of a free jailbreak tweak called NoLowPowerAutoLock by iOS developer SparkDev to command differently.

Once installed, NoLowPowerAutoLock disables the 30-second auto-lock timeout when Low Power Mode is turned on, allowing your display to stay on longer than it usually would.

Unfortunately, NoLowPowerAutoLock doesn’t let you select a custom auto-lock timeout from your iPhone’s Display & Brightness preference pane in the Settings app, but instead, it disables auto-lock altogether. We’d prefer to see the former case in a tweak of this nature, but at least you can always lock your device manually with the sleep/wake button.

At first glance, it may seem like disabling auto-lock defeats the purpose of Low Power Mode, but this feature does a multitude of other things to help conserve battery life, such as:

  • Reducing the frequency of email fetching and push
  • Disabling “Hey Siri” listening
  • Disabling background app refresh
  • Disabling automatic downloads
  • Disabling motion and other visual effects
  • Pausing iCloud Photo Library
  • And more…

Given the circumstances, you might say NoLowPowerAutoLock lets you have your cake and eat it too. Furthermore, with no options to configure, it ‘just works’ right out of the box.

If you’re interested in trying NoLowPowerAutoLock, then you can download it for free from SparkDev’s beta repository in Cydia. The tweak works on all jailbroken iOS 11 iPhones only; iPad does not support Low Power Mode.
