As you move closer to or farther away from an internet access point, whether it’s over cellular or Wi-Fi, your handset’s signal level adjusts to reflect your distance from said access point. But did you know that a weak internet signal causes your iPhone or iPad to work harder to maintain that signal?

Many don’t realize it, but the circumstances described above can have an adverse impact on your handset’s battery life. On the other hand, a new free jailbreak tweak called SignalPlane by iOS developer Julio Verne can help counteract these adverse effects with a clever Airplane Mode-centric implementation.
