Tips for improving your iPhone 4S & iOS 5 battery life … battery-gate?
The iPhone 4S sports a new rechargeable lithium-ion battery that has been upgraded from the previous iPhone 4 version. The 4S battery has been improved to a 1430mAh 3.7v unit although the new iPhone 4S runs on a faster dual core A5 CPU and a feature packed iOS 5 operating system, both of which consume more battery power. Hundreds of users are posting experiences of noticing a shorter battery life on their new iPhone 4S or older iPhones that have been upgraded to run iOS 5.

Location Services Issue and Fix
There appears to be a weird bug in iOS 5 where the location services for some apps get stuck which can be spotted from the GPS icon in the menu bar even after you’ve closed the app. You might even notice overheating with the iPhone 4S when this occurs. The best fix is to disable location services. If you don’t want to do that, since you’ll need it for Maps, be sure to at least enable the icon to appear in the menu bar as described below. This way at least you’ll know when there is an issue.
- Location Services – Settings > Location Services > System Services > Off for any unneeded features. We reccommend turning off Compass Calibration, Diagnostics & Usage, and Setting Time Zone in this section. You can also turn off the other options in this page including Location-Based iAds, Traffic, and Cell Network Search if you wish.
- Location Services Icon – Now enable the status bar icon for location services so you know when the iPhone’s GPS is active and is being used: Settings > Location Services > System Services > Status Bar Icon > On
- Location Based Reminders – If you’ve associated a location to a reminder, make sure you mark the task as complete in the Reminders app as soon possible to turn off its GPS feature.
Be frugal with services you enable
Disable, turn off or minimize all or some of the following settings and services if you don’t need them. Location Services mentioned above, iCloud, and Notifications are the biggest battery hogs. In a perfect world, with a bug free iOS, you should not have to disable anything. So, keep in mind that these tips are temporary, and you should not have to do any of these things once Apple has released or announced a fix for the iOS 5 battery issues.
