iPhone owners can use the includedLow Power Modeto save battery life on theiriPhonein 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.
Appledoesn’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 freejailbreak tweakcalledNoLowPowerAutoLockby iOS developerSparkDevto command differently.

Once installed, NoLowPowerAutoLock disables the 30-second auto-locktimeout when Low Power Mode is turned on, allowing yourdisplayto stay on longer than it usually would.
Unfortunately, NoLowPowerAutoLock doesn’t let you select a custom auto-lock timeout from your iPhone’sDisplay & Brightnesspreference 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 may 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 conservebatterylife, such as:
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.
