Want To Double Your iPhone's Battery Life? This Jailbreak Tweak Can Help

Want To Double Your iPhone's Battery Life? This Jailbreak Tweak Can Help

August 7, 2012
Countless iPhone apps and jailbreak tweaks have, in the past, promised to improve the battery life of our iDevices. However, most users report limited success with such battery-enhancing solutions (though, on a personal note, Carat recently appeared to have identified a number of battery life "bugs" and "hogs" on my iPhone handset). Nevertheless, jailbreakers are still in the market for an effective battery life-enhancing jailbreak tweak - something that works, and works well. Fortunately, with "BattSaver," it would appear that one jailbreak developer has provided such a solution. In essence, BattSaver works rather a lot like Carat - at least the ethos of the jailbreak tweak is the same as the iPhone app, and that is to identify aspects of the smartphone that are draining its battery life, and to eliminate (or suppress) them. Specifically, BattSaver concentrates on iPhone radios, i.e. Wi-Fi and cellular connections. Ultimately, the jailbreak tweak aims to better manage when these iPhone radios are enabled and disabled, thus - in theory - providing users with an increase in battery life. As iDownloadBlog notes, BattSaver allows users to choose one of five "saving strategies," three of which are preset by the jailbreak tweak itself:
  • None – No battery optimization
  • Normal – Disable radios with device
  • Aggressive – Normal, + disable data if WiFi connected
  • Ultimate – Radios must be enabled manually
  • Custom – You choose
Here's a breakdown of the three main modes. Normal Mode, when your iPhone is "sleeping," will disable all radio signals, thus saving battery life. If you're concerned about emails, worry not: the handset will briefly check every 15 minutes for new mail, meaning users of BattSaver won't miss out. Though this is indeed helpful, as iDownloadBlog notes, Aggressive Mode could be the most applicable to jailbreakers:
The Aggressive mode does the same thing as Normal mode, except it will also disable the data connection completely if WiFi is connected. The thought behind this is that you already have a valid WiFi connection, so why waste extra battery with a cellular data connection waiting as a backup? For those of you worried about phone calls and SMS messages, don’t worry, the GSM cellular radio that those services rely on is left alone. Like Normal mode, when your device is asleep, you won’t receive notifications, but instead of Normal’s 15 minute refresh period, Aggressive mode will enable your data radios every 45 minutes to retrieve emails and notifications.
Finally, Ultimate Mode - the most extreme of the three - completely disables all radio signals. It's a rather extreme method, and also rather the same as enabling Airplane Mode on the smartphone. Though all three modes provide a variation, Custom Mode allows jailbreakers to completely customize every aspect of how BattSaver affects the iPhone in question. Countless configurations can be made here, meaning users can come up with a bunch of settings to suit the individual. All in all, BattSaver is worth taking a look at - especially if you've been searching for a battery life-saving solution for some time, and have so far had no luck. Currently, the jailbreak tweak is available to download in the Cydia Store for $2.99 - though if you're a non-jailbreaker, or would like to find a solution that's available for free, consider downloading Carat for iPhone.
