Apple has already released the iOS 9 which was seen as a possible fix to some issues that previous Apple operating systems (OS) had.

The more popular issues with the iOS 9 included, of course, the problems surrounding the unresponsive upgrade screen.

Although that may have been resolved already, it seems that some folks may encounter a new issue involving the iPhone's battery life. With a thinner and lighter device now out, it seems that some iPhone 6 or iPhone 6 Plus phones are not lasting longer as usual.

This, of course, will depend on how one uses his/her phone. Some will find it sane enough to last, although the case may not be the same for ones who are heavy users. For example, for folks who have tons of background apps running plus having their data and WiFi connections on, one can just imagine the load that such bring.

The easy way to remedy it would, of course, to turn off those unneeded background apps. Aside from that, try rebooting the device, restore your device as new, or check for possible software problems.

With the iOS 9, you also get a new feature called the Low Power Mode. Turning this feature on can reportedly help as far as battery life is concerned.

To turn it on, simply head on over to the Settings and click on Battery where you can easily toggle the feature on. By doing so, you will see that your device will use less power with some graphical effects and internal operations temporarily removed. Be reminded that the Low Battery Mode feature is only available for the iPhone, meaning iPad and iPod Touch users are not covered with the option.

Then again, there is an easy way out of it — reverting to the previous OS version, which of course would be the worst case scenario.
