Although iPhone 6 and iPhone 6 Plus land with better or the same battery life as their predecessors, they can’t compare to some of the other devices on the market, which can last in some cases for days at a time.iOS 8 comes with a number of improvements but also new features that can drain your battery life even further.
These tweaks aim to extend your battery life — at times forsaking some of the new functionality — allowing you to get the best out of your new or existing iPhone
15 Ways to improve Your iPhone’s Battery Life
1.Reduce your notifications by taming your backlit display
Notifications alone don’t cause battery drainage, but simply activating the backlit display will. Applications use notifications to inform you of what’s going on in the world, such as new emails, text messages, reminders, and who is responding to you on social networks. It’s wise to set some notifications to “silent” mode, but this requires some tinkering about in the settings.
Head to Settings > Notifications. Then, under each category of notifications that you would like to mute, such as low-priority features like Photos or Game Center, tap through to each setting. Under Alert Style, simply tapNone (the left-most graphic). Repeat for each setting.
2.Modify Wi-Fi Calling settings, can save battery under the right conditions
Wi-Fi calling allows you to call people using a home or work Wi-Fi connection, rather than through a traditional cell tower. Even though it uses the more battery-hungry Wi-Fi chip rather than the cellular chip, some believe it may actually help prolong a device’s battery life. You may want to experiment, and see what works for you.
You can enable it or disable it (on selected carriers) by going to Settings > Phone > Wi-Fi Calls and selecting the option there.
3.Disable fitness tracking
Many users have reported considerable battery drain as a result of upgrading to iOS 8.2, the latest iterative update. This is because it uses sensors in your phone to determine your fitness and activity levels for the day.
You can disable it by going to Settings > Privacy> Motion & Fitnessand switching off the Fitness Tracking setting.
4.Disable cellular calls via your Mac
Thanks to a new feature, dubbed Continuity, you can now make calls through your Mac via your iPhone. You can leave your iPhone on the other side of the apartment or office, but still make calls. And if you wander off to find your phone, you can pick up the call again without missing a beat.
With a combination of Wi-Fi and cellular activity, and iCloud pinging, this feature can drain your battery life (though not as much as other features). To turn this off, go to Settings > FaceTime and then disable iPhone Cellular Calls.
5.Use AirDrop sparingly, and only when needed
AirDrop is now available for iPhone 5 devices and later running iOS 7 or later, allowing you to share files and photos with friends and colleagues over the air when they are in close proximity. But it can take a heavy toll on your battery, particularly when AirDrop is in “discoverable” mode.
Simply swipe up from your home screen to bring up theControl Center, then tap AirDrop. Select Off when you’re not using it.
6.Limit apps from churning up data, power in the background
You can now limit which dormant apps download data — therefore consuming power — in the background. For instance, while it may be useful for a mapping app to provide you with up-to-the-minute turn-by-turn directions on the road, you may not want other apps, such as the Stocks app, to update if you’re not particularly interested in the financial market.
To change this setting, tap through to Settings > General> Background App Refresh, then deselect apps that you do not want to update in the background.
7.Disable auto app updates; manually update at your convenience
iOS 7 (and iOS 8) lets you update your apps and music in the background. If you’re connected to Wi-Fi networks (or the cellular network), your apps will remain up to date without bugging you. But this consumes data and power, and should be restricted for when you’re free to plug in your iPhone to charge.
Go to Settings > iTunes & App Store, then turn off theUpdates and Apps settings. Another quick power (and data) saving tip: You can allow updates when you’re on Wi-Fi only by deselecting Use Cellular Data at the same time.
8.Block persistent callers from contacting you
Calls significantly drain your battery meter, even if you don’t pick up incoming calls. If you get the same persistent person calling, you can now block them from reaching you.
To do this, head back to Settings > Phone > Blocked and select the contacts you wish to automatically refuse access. While this feature blocks the call coming through, it doesn’t prevent the caller from leaving you a voicemail.
9.Prevent your iPhone from ‘learning’ your frequent locations
Your iPhone running iOS 8 records where you go so it can pick out nuggets of information that may help you, particularly if you visit those places regularly. It updates the Today section in your notification center, and can give you estimated times of arrival to your destinations. While it’s a handy feature, it is far from absolutely necessary, and can be turned off to save some valuable battery.
This one is buried deep down in the device’s settings. To get there, navigate to Settings > Privacy > Location Services > System Services, then switch off the Frequent Locations option.
10.Switch off Handoff apps from iPhone, iPad to Mac
Handoff allows you to pass over your work, a message, an email, or a browsing session to another device, so long as it’s connected to your iCloud account, such as your iPad or a Mac. Handoff doesn’t miss a beat.
Though Handoff is a useful feature, it can also add to battery drain. To disable it, go to Settings > General > Handoff & Suggested Apps,then switch it off.
Also, disable My Apps and App Store to prevent apps associated with your general location from appearing on your lock screen. This additional feature also uses your location, which churns up unnecessary amounts of battery.
11.Prevent iTunes, App Store from churning up cellular data
Your iTunes collection and App Store downloads can be added to your device over-the-air. But downloading over a cellular network can rinse your battery life — especially if you have a lot of apps.
Go to Settings > General > iTunes & App Store and switch off the Use Cellular Data option. This means your apps will only update when you’re on a faster Wi-Fi connection, which takes less time and reduces your battery drain.
12.Disable unnecessary iCloud items
iCloud syncs your iPhone with your iPad and other Mac devices. You may not however need everything synced up-to-the-minute. You can disable some of these items, such as Safari syncing and Notes syncing, by going to toSettings > iCloud > and disabling various options from there.
13.Turn off ‘parallax’ background motion
If you slowly jiggle your iPhone in your hand, you may notice the “parallax” effect of three-dimensional icons sitting on top of your wallpaper. This effect uses internal hardware to sense the direction, speed, and motion of your movements. This, as you might expect, will drain the battery. Though flashy and visually quite cool, it’s not wholly necessary if you’re a power user.
To disable the “moving wallpaper” feature, head toSettings > General > Accessibility > Reduce Motion, then switch this option on.
14.Prevent Spotlight Search from indexing unnecessary files
Spotlight regularly indexes your entire iPhone’s contents in order to serve up the best results. This may not use up a whole lot of processing power, but it’s certainly helpful in the long run to remove items from the list that you don’t use.
You can select which areas of your phone to index by heading to Settings > General > Spotlight Search and tapping any item you wish to exclude from the search index.
15.Disable auto-brightness and adjust manually
Some believe that the iPhone’s “auto-brightness” feature will help conserve battery life by dynamically and automatically increasing or reducing the brightness of the screen, based on how light it is around you. Yet, others argue that this alone can actually lead to the battery draining. It may not be easy to read your iPhone’s screen in direct sunlight, and you may not get the most out of your high-resolution display, but this is about conserving your battery rather than anything else.
The best practice seems to point to disabling the auto-brightness. Go to Settings > Display & Brightness, thenreduce the brightness to 10-25 percent, or depending on your personal preferences.
