Although, Apple brought grin to quite many faces when it demonstrated how the new iOS 9 will add some extra breathes to your iPhone’s battery, what disappoints is the performance that would be very much compromised in order to claim this extra battery life.
As per the tests ran by MacRumors, it was found that Low Power mode can reduce the performance of an iPhone by as much as 40%, giving you extra battery life to content with. But if you intend to get this extra battery life, you will have to compromise with your device’s performance.
The test reports show that on turning on the Low Performance mode, iPhone 6’s performance will slump by a substantial degree and will lie somewhere between that of iPhone 5 and iPhone 5s. This might sound like a massive performance drop if you are a “performance conscious” guy.
The iPhone 6 Plus gained a score of 1606 on Geekbench 3’s single-core processor test and a score of 2891 on the multi-core processor test. When the Low Power mode is activated, the device recorded a score of 1019 on the single-core processor test and a score of 1751 on the multi-core processor test.
This dip however comes rather unsurprisingly, since iOS 9 promises to offer extra battery life by reducing the CPU clock speed as well as cutting some background activities.
As described in the update details –
Low Power mode temporarily reduces power consumption until you can fully charge your iPhone. When this is on, mail fetch, background app refresh, automatic downloads, and some visual effects are reduced or disabled.
However, considering how performance dip is sharp, you might end up being frustrated with your iPhone’s sluggishness than appreciating a longer battery.
Along with more battery life, the operating system will also focus on some storage issues. It will take up a smaller amount of space on the device, requiring 1.3GB of free space to install, rather than more than 4GB of space that was required by previous iteration.
iOS 9 will be available for developers starting on Monday and, for the first time, available as a public beta in July. It will eventually be available as a free upgrade for everyone in the fall.
