So much of our lives are spent using our smartphones these days, and yet they’re still powered bybatteriesthat hardly seem to last a full day without needing a charge. Apple’s Low Power Mode is helpful when you want to take advantage of every last drop of battery life, but when you demand even bigger extremes, a newly releasedjailbreak tweakcalledUltraPowerSavingModeby iOS developerPrasajust might be a better choice.
In a nutshell, UltraPowerSavingMode attempts to duplicate theApple Watch’sPower Reserve modeon the iOS platform, albeit in quite a far more advanced manner. Once toggled, the tweak optimizes your handset’s power usage to help you maximize battery life well beyond what the nativeLow Power Modeis capable of.

UltraPowerSavingMode can disable selected jailbreak tweaks on demand to reduce the strain of battery-intensive tweaks, automatically toggle itself on or off depending on the device’s charging state charge more quickly or discharge more slowly, and automatically close out of all backgrounded apps to reduce memory usage and save power.
In addition to these features, UltraPowerSavingMode doesn’t hinder your alarms, provides pleasant haptic feedback, and can announce the current power state with local orSirivoices. The tweak can be toggled on or off easily with aControl Centertoggle, and you’re able to even see a live view of your device’s current stats with a gesture when UltraPowerSavingMode is turned on.

As you might time to expect, an Apple Watch-style power reserve mode on the iPhone effectively locks you out your iPhone’s most enjoyable features for the added benefit of additional battery life. It can help ensure that you make it a day (or perhaps more) on a single charge, whereas traditional usage can drain the battery in mere hours.
Given the circumstances, one might not feel compelled to use UltraPowerSavingMode all that often. But when your battery gets low enough and you only need to glance at essential information every now and again, it can definitely become useful in a pinch. Best of all, it’s easier to exit UltraPowerSavingMode than it is to leave power reserve mode on the Apple Watch, which means all your iPhone’s best features are never too far out of reach.
