iDevice Battery Saving Tips
Want to squeeze the maximum battery life out of your iDevice?
Try the following 11 iDevice battery saving tips out:
1) Disable Push
– Settings > Mail, Contact, Calenders > Fetch New Data > Push – Set to “OFF”
– Set “Fetch” to “Manually”
– In “Advanced“, set each mailbox to “Manual”
Note: With Push enabled, as soon as a mail is received you get a notification on your phone. Once push is disabled, the Mail app will only check for new mail when you open the Mail app. This gives you more control over your battery life.
2) Disable Certain Location Services
iOS 6 – Settings > Privacy > Location Services
iOS 5 – Settings > Location Services
Turn off location services for the apps that you do not want to collect your location info.
Note: e.g. For the camera app, the location that the picture was taken is recorded in order to “Geotag” the photo, to show you exactly where you took the photo on a map like in the “Places” tab of the stock Photo app. For an app such as Facebook, your location can be used to “Check In” to places. So you may want to leave location services turned on for certain apps.
– In the same Location Services screen, scroll down to “System Services“. Disable any unnecessary system services that you do not think you would use. People who travel frequently may want to leave “Setting Time Zone” option to “ON”
3) Enable “Limit Ad Tracking” (iOS 6 only)
Settings > General > About > Advertising > Limit Ad Tracking – Set to “ON”
What this actually does is limit the information that apps send to advertising networks for the purposes of delivering more ‘relevant’ or ‘targeted’ ads across apps.
We discuss this option in more detail in our news article here
4) Decrease Brightness
iOS 6 – Settings > Brightness & Wallpaper
iOS 5 – Settings > Brightness
Set brightness to the lowest possible value that you can bear.
– Turn “Auto Brightness” toggle to “ON“
Note: Auto brightness uses the built in ambient light sensor of the iDevice to detect the ambient lighting conditions in order to set the optimal brightness for less battery drain. For example, when it’s dark, it will reduce your brightness as it does not need to be so bright. Also note Apple have removed the ambient light sensor in the new iPod Touch 5G.
5) Disable Wireless Radios when not in use (WiFi, Bluetooth etc.)
When you are not using them, turn your wireless radios off. This includes 3G, Bluetooth, and WiFi.
If you want to completely disable all wireless radios (including your cellular signal which you use to receive calls), simply enable Airplane Mode in Settings > Airplane Mode > ON
Settings > iCloud
iCloud is great. Again if you don’t know what it is, you’ll probably want to turn it off. If you do know what it is, then only enable the services that you use.
– In the “Documents & Data” section, set “Use Cellular Data” to “OFF“. This will not only save you data usage, but also battery life.
7) Spotlight Search
Settings > General > Spotlight Search
If you don’t know what Spotlight is, you should probably turn it OFF! Spotlight is the built in Search feature on iOS which indexes your entire phone for quick and easy search results. You can access it by swiping right at the first page of the home screen, or by pressing the home button at the home screen/springboard.
Untick all the items you do not want indexed. If you do not use Spotlight at all, that’s ALL of them!
Settings > Notifications
Disable any unneccesary notifications. The less notifications the OS has to present to the user, the more battery life it has at its disposal. Simple as that.
9) Enable Auto-Lock
Set this according to your preference (1-2 minutes usually works best).
10) Disable Diagnostics
Make sure that diagnostics is disabled in Settings > General > About > Diagnostics & Usage
11) Other Tips
Heat – Lithium Ion batteries do not like heat. Always try to leave your iDevice in the coolest possible area so that it can stay cool. For example, do not leave it in the heat of your car as this will affect your battery life.
Full Charge Cycle – Try and perform a full charge cycle at least once every few months. This ensures that the battery life reported by the OS is accurate. You might not want to do this too
Reserve Initial Judgement – You just got your first ever iPhone or other iDevice, or just upgraded to the latest and greatest iOS version. Naturally, you are going to be playing around with the device more than usual in order to explore new features and changes. Over time, this “playing” time will decrease, and as a result, your battery life will be more representational of normal usage.
Keep Apps Updated – Developers are constantly improving apps, and as such, such changes often include battery life improvements. Keep your apps up-to-date.

Wired.com have a nice write-up dispelling common battery life myths which is worth a read:
[quote]Myth 1: Killing Background Apps Extends Battery Life
Killing background apps will not extend your battery life. Those apps are effectively “frozen” in the background and, according to Apple’s own support documents, multitasking does not put unnecessary strain on the battery. The exceptions to this rule are apps which use ambient location services (aka “Geofencing”), background audio playback (the play symbol will appear in the status bar when audio is playing even if the volume is off), and background downloads in Newsstand. As we’ll see, however, you can turn these background features off selectively without quitting the app.
Myth 2: Calibrating Improves Battery Life
It’s impossible to physically measure how much power remains in a battery. Because of this, mobile device manufacturers have developed sophisticated algorithms to estimate the remaining charge. Still, over time the reading will begin to drift away from the actual value.
Calibrating (using the phone until it dies then charging to 100%) helps snap these readings back into place. It does not, however, extend battery life; it mainly makes the indicator more accurately reflect the battery’s state. Apple advises users to calibrate monthly, but any more often is overkill. While there are some ancillary electrochemical benefits to running full charge cycles, in practice you shouldn’t have to worry about this too much if you’re using your phone regularly.
Myth 3: Overcharging and Overdischaring Damages Batteries
While overcharging or undercharging is a concern for gadgets that use lithium ion batteries, Apple has built-in protections to keep these things from affecting iOS devices. As All Things Digital recently reported, when the battery fills up, the phone will let it drain to 99%, then fill back up. This cycle will repeat as long as the phone is charging, although the battery indicator will report “full” rather than reflecting the actual fluctuating charge to avoid distracting users.
Likewise with letting the battery “die” too often. (I use quotes around the word “die” because all lithium ion batteries will actually shut off with a bit of charge remaining as a safeguard against damage from overdischarging.)
What will damage batteries, however, is letting the phone die and then tossing it into a drawer for two months. Batteries lose charge over time even when not in use, and letting the battery sit with little to no charge will cause it to lose capacity.
Myth 4: iPad Chargers Charge iPhones Much More Quickly
iPad chargers deliver twice the current as iPhone chargers (2 amps instead of 1 amp). Both are five volts, but the iPad charger has double the wattage as well. (Remember Physics? Me neither. Current, measured in amps, is equal to Wattage divided by Voltage.)
But wait! Current isn’t the only factor in charging time. Batteries charge in three stages: The first stage, constant current, is the only one where the battery might use the maximum amount of current that the charger can deliver. But even then, most devices with lithium ion batteries will limit the current to only what they need via software controls.
What this means in practice is that while you will get a quicker initial charge from an iPad charger due to the higher current, the extra current won’t be drawn throughout much of the charging cycle. And since batteries charge much more quickly at first, slowing down as they reach the final 20% of capacity, you probably won’t notice much difference unless you’re running really low.
In addition, it means that if you’re in a hurry you should avoid charging your device through your laptop. Newer MacBooks will detect iPhones and iPads and deliver half the current as the device’s equivalent wall adapter. Gizmodo did a side-by side comparison of different power sources that illustrates the difference nicely.[/quote]
