Low Battery Mode might be my favorite thing about iOS 9. It radically improves battery life on an iPhone when your device dips down to 20%.
The only problem? Once your iPhone charges a sufficient amount, Low Battery Mode automatically switches off. Which is a shame, because if you kept Low Battery Mode on all the time, you could eke out hours more battery life from iOS.
Sadly, iOS 9 doesn’t let you keep Low Battery Mode on all the time. But if you’ve got a jailbroken device? That functionality is just an install away.
The tweak is called LowPowerMode (wonder where they got that name from) and it’s available on Cydia’ BigBossRepo. It basically allows you to keep all of Low Power Mode’s features on indefinitely, maximizing battery life regardless of how much of a charge you’ve got left.
What does Low Power Mode do? Here’s what Apple lists in their official support document as being reduced or turned off when you switch on Low Power Mode:
- Email fetch
- Hey Siri
- Background app refresh
- Automatic downloads
- Wi-Fi associations
- Some visual effects
Since I rarely want most of these features on my iPhone, I think this is a pretty worthwhile tradeoff for an iPhone that runs a couple more hours per charge.
Unfortunately, right now, if you want permanent Low Power Mode, you need to have a jailbroken device running iOS 9. Fingers crossed that Apple allows you to permanently turn on Low Power Mode in iOS 10!
