Disabling ‘Setting Time Zone’ May Improve Battery Performance Of Your iPhone 4S





iphone-battery-iconLow battery life is one of the major issues for early iPhone 4S owners who constantly searching answers on Support Communities forum. Thus far Apple has remained silent about the matter. It appears that the problem is also affecting some iPhone 3GS and iPhone 4, suggesting that it is rather a software defect than a hardware problem.

iDownloadBlog reports on interesting remedy that helped some users to improve the battery performance. The Setting Time Zone feature in iOS 5 appears to cause excess power consumption as the device repeatedly detect user location to set the time zone. To turn off this functionality, open Settings App, go to Location Services, System Services and disable the Setting Time Zone function.To make your iPhone last more, you may also want to switch off Diagnostics & Usage and Location-Based iAds in this menu.

system services

Apple offers this advice to improve battery life of your iPhone:

“Be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down)”.

Macworld’s mentions launching a system diagnostic app in order to pinpoint which unnecessary processes are running in the background and discover the cause of rapid battery drain.

iPhone 4S Component Costs Once Again Begin at About $188



isuppli_iphone_4s_teardown

We have already seen some teardowns and estimates of the cost of the new iPhone 4S by iFixit and Chipworks. Now iSuppli offers its teardown and some new facts.

In the case of the iPhone 4S, [IHS iSuppli analyst Andrew] Rassweiler estimates that the BOM cost ranges from $188 for the 16 gigabyte version of the iPhone 4S to $207 for the 32GB version and $245 for the 64GB version. Apple and its carrier partners sell the phones for $199, $299 and $399 respectively, typically with a two-year contract for wireless service that carriers use to subsidize the cost they pay Apple.

iSuppli didn’t find in the iPhone 4S a noise cancellation chip from Audience that was found in the iPhone 4. Such function may be implemented directly into A5 cheap that costs about $15. While iFixit found Toshiba flash memory in its iPhone 4S unit, IHS iSuppli expressed some surprise at finding Hynix memory in its unit. But as far as we know, Apple sources flash memory chips from different manufactures. They didn’t managed to find the manufacturer of the camera sensor, but estimated the cost of the camera module at $17.60.

RedSn0w 0.9.9b6 released: iOS 5 jailbreak for Windows and fixed location services for 3GS



redsn0w-099b6

The iPhone Dev-Team released jailbreak utility RedSn0w 0.9.9b6 for both Windows and Mac users. The new version offers full iOS 5 jailbreak support for Windows and fixes Location Services issue for iPhone 3GS devices running the 06.15 baseband. This is still a tethered jailbreak for iPhone 4, iPhone 3GS, iPad 1, iPod Touch 3G and iPod Touch 4G:

We've released version 0.9.9b6 of redsn0w, with both a functional fix and cosmetic fix for iOS5 jailbreakers. For iPhone3GS owners with the 06.15 baseband, this redsn0w eliminates the network crash you saw when using Location Services in iOS5 (in fact, you don't even need to disable Location Services anymore during the initial setup). The cosmetic fix is to the visual countdown you see when going into DFU mode.

It's okay to re-run this redsn0w over an existing device jailbroken at iOS5. Just choose "Jailbreak" again and de-select Cydia (in other words, all the checkboxes will be unchecked). If you are lucky enough to have an old-bootrom iPhone3GS, please pre-select the IPSW first (redsn0w can't yet auto-detect the FW version of your old-bootrom 3GS if it's already been jailbroken).

Just as redsnow 0.9.9b5 the new version supports creating custom firmwares with preserving baseband (modem) version for unlock. Unfortunately right now custom firmware functionality works only with Mac version.

You can download the latest RedSn0w version here.

UPDATE: RedSn0w 0.9.9b7 released. Minor change, it has an option for a faster jailbreak. Get it here.

UPDATE:
Here are links to our RedSn0w 0.9.9 iOS 5 jailbreak tutorials:
