One of the main complaints of the modern smartphone is that their battery life seems to have just decreased over time. Yet that is not entirely true – these days phones have so many antennas and sensors, that the phone is almost constantly draining power from an ever increasing battery size. Manufacturers have had a tough time – on the one hand phones are becoming ever slimmer and lighter, with more power draining features, yet the battery life has to improve as well with every generation. So battery technology hasÂ definitelyÂ improved, but our demands are just greater than ever.
If you use your iPhoneÂ intensively, you are looking at around a day long battery life, but it can quickly run out within a workday if you are particularly busy with your phone. But there are a few things you can do to make the battery last that little bit longer.
iOS7 is a major upgrade of the operating system, and has created a few new options that can potentially hammer your battery life. The same battery tips as always will still work with iOS7 – so we included them in this post. In fact, they are just as important as ever, so we start with the big ones first.
The main idea behind these tips is that you so not have to impede the functionality of iOS7. Its a great operating system, and it would be a shame to go and switch almost all functionality.
These are the settings I use which do not limit the functionality of the device:
1) Wifi reception:
If you are not using Wifi at home or work, switch it off. But, if you are using Wifi a lot, you will save battery power if the phone does not have to constantly check for new networks.
Go to: Settings -> Wifi Networks -> Then switch off “Ask to Join Networks”.
Also, using Wifi does use less battery power than 3G or LTE. So if you have the ability to connect to wifi networks at home or work, use them. Also, while we are talking about radios – if you do not use Bluetooth anywhere, keep it switched off as well…
2) Push Email and Push Notifications:
This seems to have a very big effect on battery life, especially if you have multiple email accounts, and many apps.
You have to ask yourself – do you really need to have a constant connection to your email? Do you have to get that email or meeting request the moment it is sent? Or is once every 30 minutes enough to keep in contact? Obviously if you are dealing with on the minute deals (or whatever), keep Push Email on. But here is how to deactivate it:
Go to: Settings -> Mail, Contacts and Calendar -> Fetch New Data -> And change the “Push” switch to Off.
Then go and set at which interval you want the phone to check for new mail and calendar entries. I personally set it to 30 minutes, but its your own preference. If you only want the phone to check for Mail only if you open the app, select “Manually”.
Push notification services are great, but are not needed for every single app you have. For example – getting a notification if your share portfolio falls 10% is a lot more handy than Angry Birds asking you why you havent played in a few days. Push Notifications require the phone to make multiple connections every hour in order to not miss out on messages, regardless how important they might be. Best idea – control those apps. Here is how:
Go to Settings -> Notifications then go into every app where you dont need notifications:
For example: Go into one your games, and then go ahead and switch off all notifications for that app:
You can also be very choosey – e.g. you might not need twitter replies to appear on your phone’s Lock Screen (so the screen does not need to light up with every twitter reply), but you do want a banner ad to appear when you unlock the phone:
It does take some time if you use a lot of apps, but the battery life gains will be worth it.
3) Screen Brightness and Sleep
This one is pretty obvious. That screen on the iPhone does take some juice to stay bright. So go try a slightly lower setting, and see if you are able to live with it. Most iPhones ship with the screen at half brightness, but you might just find that using a slightly lower setting might work fine, while saving your battery in the process. From iOS6, Apple has made the Auto-Brightness changes a lot more aggressive (and quicker to react), so I recommend keeping it on.
Go to: Settings -> Brightness. Slide the control to the left to decrease the brightness. Also ensure “Auto Brightness” is switched on.
Also, you should set your Auto Lock time to 1 minute. Do you really need the screen to stay on for 2+ minutes if you are not using the phone?
Go to: Settings -> General -> Auto Lock. Choose 1 Minute.
Sleep: OK, I only wanted to give tips that do not impede on your usage of the iPhone – and this is the only one that takes some getting used. Luckily some of us do this already, but many do not. Its pretty easy. When you are done using the phone, just put the phone into sleep mode, by clicking the button on the top right of the device. This will prevent the screen just staying on, and many apps will actually go into a sleep state, which saves power. This tip goes for any modern touchscreen phone, not only the iPhone.
4) Location Services
OK, now many articles tell you to just switch this off. But that is one step too far in my opinion – after all, many of the best uses of any iDevice relies on the GPS sensor inside. Problem is these days just about any app you fire up quickly uses location services to check where you are, and if you many apps in a day, that is quite a lot of little checks using triangulation and GPS coordinates, all taking battery power. Now think about it – if you open up Facebook, Twitter, and News24 multiple times a day, do you really need the app to check your location every time? Not really. Time to control all those apps.
Here is how you do it:
Go to: Settings -> Privacy Â -> Location Services -> keep the top switch on.
You will see all the apps that can use location services below that. You can go and disable all the apps that you do not want to use location services in (do you need to have Angry Birds check where you are?). iOS also gives you some pointers – all the apps that have used location services in the past 24 hours will have to little grey location service icon next to it. Apps currently using the GPS will have a purple GPS arrow next to it. Obviously navigation apps should have location services switched on, and you might want to have the location stored of every image you take, so keep Camera on.
There is also a slightly more hidden location service called “System Services” right at the bottom of that list of apps. Click on that, and disable any of the services you do not use. Frequent locations can be quite a battery hog if you move around a lot. Frequent location is used by notification center to let you know how long it will take to reach a frequently visited location:
5) Learn how to use Multitasking, and How to Kill Apps
Multitasking is one of those features that Apple only added later to iPhone in iOS 4, somewhat begrudgingly I guess (due to many requests over time by power users). But now that it is available, many people are not even aware of it (and how to manage it). They just keep using the phone they always have, without ever opening the multitasking dock.
Apple’s implementation of multitasking is pretty smart in that it freezes most apps when not in use, but then only allows certain services to run in the background, for example the GPS sensor for a navigation app. This results in supposedly better battery life than most other smartphones, but it still helps to learn how to kill apps if necessary.
Double Click the Home Button – you will see that a carousel of currently running apps pop up, showing a preview of each app running.
You can swipe left and right to move between currently running apps – or simply swipe a preview upwards. This is used to kill apps.
This last tip is only needed now and again – for example, I only use it after I used the Co Pilot navigation app on my phone (see our review here). Otherwise I tend to leave background apps going, but you might discover some app that still uses some or other allowed service. If you are unsure, go ahead and kill all background apps. Do not worry, it will not delete the apps.
6) Some new iOS7-Only Battery Hogs:
First off, switch off Background App Refresh. This is a new feature that allows certain apps (if developed correctly) to run in the background either continually, or at predefined times. Right now not too many apps properly support it, so you might as well switch it off. Or switch it on for only apps you want to run in the background.
Go to Settings – General – Background App Refresh.
Secondly – Airdrop. Airdrop is a pretty great feature carried over from Mac OS X, which allows you to instantly share to any other compatible device using a combination of bluetooth and Wifi. But if no one around you is using it, there is no reason for your device to be continually broadcasting its availability, right?
Simply flick up from the bottom of the screen to see Control Center. From there you can change Airdrop discoverability settings.
By just using these few tips I have pushed my iPhone’s battery to more than a day. Your mileage might vary depending on how much you use it. As a bonus, all of these tips should work with iPad as well – but then again the iPad has much better battery life that you might not even have to bother…
