iOS 11 battery life drain percentage now seems to be on par with iOS 10, at least that is how it is on the devices we have iOS 11 betas installed.

How does the battery life and performance compare on iOS 9.3.1 vs iOS 9.2.1 running on an iPhone 6s? Check out this video to find out.

Facebook mobile app is known to burn through iPhone and Android devices’ battery life. As it turns out, using the service in a web browser like Safari or Chrome can save 15-percent battery on your iPhone and up to 20-percent on your Android phone.

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.

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?

The recently released PwnageTool / Redsn0w jailbreak tools for iOS 4.2.1 requires you to transfer iPad’s 3.2.2 baseband to your iPhone 3GS & 3G in order to unlock it using Ultrasn0w 1.2. This has resulted in poor battery performance as has been experienced by many users. Some users have also complained about their device becoming very hot when in use.

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.

There is no doubt about the fact that iPhone is one of the most popular cell phone out there. The argument for a longer battery life on the iPhone is relative in terms of its user requirement. If used as a cell phone, for the primary purpose that it has been designed for, the battery life would be fine and will last probably all day. However, if someone likes to use it as portable computer which I assume most iPhone users are doing, for checking email, web browsing, playing games etc, then the battery is comparable to that of any standard notebook at best.
