Here's how iOS 9 saves battery life on your iPhone and iPad

Here's how iOS 9 saves battery life on your iPhone and iPad
Apple is adding a couple of battery enhancements to iOS 9. First, battery life on the iPhone and iPad will be increased by one hour once the latest build of the OS is installed. This is accomplished by using things like the proximity sensor which turns the screen off when it is face down on a table, even if a notification arrives.

In addition, Apple is offering a Low Power Mode that will add an additional three hours of battery life to your iPhone or iPad. How is this accomplished? What kind of black magic is Apple calling on to keep you from turning into a wall hugger? The Low Power Mode can be turned on at any time by clicking on settings and going to battery. iOS 9 will also prompt you when the battery life drops to 20% and 10%, asking if you want to turn on the feature.

To squeeze out the three extra hours of battery life, the mode turns off sensors. Push notifications for Mail are shut down and the screen brightness is lowered. In addition, the screen goes to sleep faster and no background refreshing is allowed. Motion settings are reduced and wallpaper animations are stopped. Network speed could be lowered in order for the Low Power Mode to reach the 3 extra hours that Apple says it can add.

This isn't anything new to Android users who have seen phones from certain manufacturers offer battery saving modes that shut down many features in the name of longer battery life. The Power Saving Mode on the Samsung Galaxy S6 throttles the CPU speed, reduces the screen brightness, frame rate and more. The Ultra Power Saving Mode changes the screen to a greyscale while disabling many apps. Android 5.0 comes with a Battery saver mode that stops vibrations, reduces performance and stops some apps that rely on syncing, from updating. This feature can be turned on manually, set to automatically go on with 15% or 5% battery life remaining, and will prompt you when your the power in your juicer is down to its last 15%. The feature is said by Google to add 90 minutes of battery life to an Android device.

Extending battery life in this manner is a new experience for iOS users who are more used to adding battery life through accessories like the Mophie Juice Pack.

Kababayan. Wow that is expensive. I have the Verizon S6 Edge. Verizon tends to stick to the lower price vs any carrier. iPhone 6 $649 749 849 iPhone 6 Plus 749 849 949 S6 $599 699 799 S6 Edge 699 799 899 I did put tax because taxes vary by State (Province if you prefer) Tax in Chicago is 10% per 1.00 so I paid 988 for my 128GB S6 Edge in Gold. Cheaper than any iPhone on any. Arrieta plus BTW is cheaper with the GALAXY than any carrier in the USA as well.

Your high, apple doesn't lower prices for ANYONE. And they surely don't offer a 128GB for only 20$ more then a 32GB Sammy device.. post the link buddy.

That's why my previous comment should be considered an opinion yes? Oh sure they are. Even the grey units of 128gb iphone 6 costs $895 from online stores. Not surprising though since iPhone 6 is months old already.

Storage and accounts, sure, USB debugging, no way, since it's not much different from having your iDevice jailbreak, lol.

With all these iOS 9 and android m's power saving features, I am excited how gionee marathon m5's extreme mode will work on their 6020mah battery. I am looking forward seeing a PA review on this and topple huawei ascend mate and z3 compact as king of batteries.

This same function had already been available on both BlackBerry and Windows Phone, too. Its good to see Apple finally added it.

I believe he is serious about it and there is nothing wrong about it. The only thing that is close to dead is your brain. I am not a iOS/Android hater, and I love it as much as I love Windows Phone/BlackBerry 10. We love technology, that the reason why we are here, if you want to troll, please troll somewhere else. Thank You.

It's trolls like you that make iOS users look bad, and fully deserve the term "!Diot". All your proving is how much of an !Diot you are with every post.

You're obviously a troll that doesn't know anything about technology. I don't give two rats scrawny b***s how big iOS is, it's dwarfed by Android in mobile, has absolutely nothing on BlackBerry in enterprise and government, and is tiny compared to how many machines run Windows as opposed to any Apple device. And for the record, what I said is absolutely TRUE. BlackBerry and Windows as well as Android had these features long before iOS did.

You logic is like my old logic when I was an Nokia Symbian user. We have all the features but with lags and every hour we need to restart the device to let these features work well. The difference between Apple and the others is that Apple gives us the feature in the right moment and in a perfect way. Hopefully you will understand what I said but I'm not sure you can. Enjoy restarting your devices to gain more RAM and more speed.

WTF are you talking about? My Passport has 3 gigs of RAM, doesn't restart and flows beautifully. You're precious iDevice doesn't even multitask anywhere near as well a BB10 does. Windows Phones don't lag and restart either. Have you ever even used any BlackBerry 10 or Windows Phone device to even know what you're talking about? As I said, you're an !Diot that makes other iOS users look bad.

I expect my phone to work without any compromised from 100 down to 1 percent capacity. That is why I have always used extended higher capacity batteries on all my recent phones. Now I rock a Galaxy s4 i9500 with a kiwibird extended battery case. Get around 9 hours of screen time with heavy usage

This is by far my favorite feature of iOS 9. And btw, the only data we have is that iOS 9 is going to increase the battery life by an hour/4 hours in power saving mode on the iPhone 6. I think older iPhones can be impacted similary, but the iPhone 6 Plus and especially the iPad will seee less of the benefit as most of their power comsumption goes trough screen which can be at best dimmed down to save power. Considering iOS 8.3.1 improved battery life a bit I am really excited about this. And when this newer, much more efficient software will met the next generation of efficient hardware (and a bigger battery), it will be a real killer in terms of battery life !
