Battery retention is an essential consideration to make when deciding which smartphone to buy. While juice-o-meter gradually loses strength over a period of time, we tend, also, to lose our patience, and there is perhaps nothing more irritating than realizing you're out of battery, when you thought you had at least ten percent! Still, such is the culture of this digital age, there's an app for that, and while there are perhaps more battery utilities out there than device units sold, it's a field that just continues to grow. Battery by Iurie Iurceac wades into the densely-populated field with a very interesting entry, and as well as swamping you in a frenzy of statistical data, also helps you learn how best to take care of your battery.
Much like the signal issues with the iPhone 4 release last June, the launch of Apple's much-improved dual-core model has been dogged with problems - the battery being the main culprit this time around.
With the various reports of Apple's latest smartphone sapping battery life faster than a vacuum, the company's engineers are said to be scrambling for a fix.
One of the many complaints leveled at the iPhone design is the closed case, with no user-serviceable batteries. This has spawned multiple cases with inbuilt power supplies for extending the iPhone's sometimes anaemic battery life. Granted the iPhone 4 is a great improvement over past models in the power department, but every little helps. But what if you don't want a case with the added bulk of a battery?
There is now a new jailbreak application available on Cydia which helps in extending battery life on iPhone 4, 3GS and 3G. Available by the name of Auto3G on BigBoss repository, this app basically turns off the 3G radio and switches to 2G (EDGE) when you lock your phone, and turns it back on as soon as you slide-to-unlock your phone again.
Battery Percentage meter option is officially available on iPhone 3GS only running firmware 3.0 and above; however, there is a small tweak available in Cydia which can enable this functionality natively on the original iPhone and iPhone 3G running firmware 3.0 and above. You will need to have a jailbroken iPhone for this to work.
