Since the launch of the iPhone 3G, people have been complaining about how bad the iPhone’s battery life is. 40% of iPhone users say that their iPhone does not last a whole working day (I’m really not sure what they are doing with it then) I personally think the iPhone’s battery is well equipped – It is a smartphone after all, its only designed to last a day. I think people think its bad because it doesn’t last as long as their old Nokia 3210 back in the year 2000.
The new iPhone 5 has had better reports of battery life than any other iPhone yet, This is understandable considering its considerably larger, though there is no need to upgrade just yet, your current iPhone can last well over a day if your willing to sacrifice a couple of things. There are plenty of things you can do to save battery life on your iPhone and I’m going to list some for you.
Turn off WiFi and Cellular
I would turn off WiFi if you are using it – This way it can’t try and connect to any wireless networks on your commute to work or while your just in the car. You could also turn off your mobile data if you really want to save battery, but my personal opinion is kind of against this, though it does help the battery life a lot – It also takes away everything your iPhone is made for, You’ll have no internet connectivity so you’ll receive no notifications for any applications that require network access – Your iPhone will become as useful as that Nokia 3210 you loved so much (Though it can’t play Snake, You’ll need mobile data for that)
This one is a biggy, do you really need the brightness on all the way to the top. Yeah it looks fantastic on your new 4 inch retina display but your battery will be hating you for it. Just turn it down to half way or something, still looks good and you can still see your screen – Magic! You should also leave Auto-Brightness on as this dims the screen if you go into a dark room, since you won’t need the screen so bright.
Turn off Location Services
I recently wrote a post on why Location Services on your iPhone can be dangerous, If you don’t need it on – Just turn it off, You’ll be thanking me later as this uses a hell of a lot of battery on your phone. Note that stock apps like Maps and Weather will also not work as they need location services running to give your their useful information.
Change Your Email Settings
If you have several email accounts setup on your iPhone like me, this can cause battery life to drain quite quickly since its always receiving new data. There is a simple fix for this though, Go into your email settings and change your email accounts to fetch either manually or every 15 mins or so. You may be delayed on your emails but at least you can still play Angry Birds on your lunch break now. Take note that switching to the Manual setting is actually not so bad, It takes all stock apps into consideration, so if you receive a text message and swipe to reply, You iPhone will do a quick search to see if you have any new emails too, not so bad eh?
Stop Your iPhone From Stalking You
This is default on any apple device, going back to Location Services – your iPhone knows where you are all the time and it tries to show you advertisements based on this, it also looks for traffic in your area and finds apps based on your location and your taste in software. All of this can be disabled and can cause your iPhone to be a bit happier during those long days, to disable these settings go to Settings > Privacy > Location Services and then scroll all the way down to the bottom to find System Services, tap that and disable: Diagnostics & Usage, Genius for Apps, Location-Based iAds and Traffic. You could also disable the setting time zone option if your not planning on moving around very much.
Power Cycle Regularly
If you think your iPhone is not performing how it should be and it is losing battery fast. You should try restarting your phone more often, but as general rule – You should do a full power cycle of your iPhone at least once a month. This means you must let your iPhone run all the way down until there is nothing left, and then leave it on charge for a full charge without using it much. You might not a battery boost from just doing something as simple as this.
Turn Off Notifications
You should really turn off notifications for apps that you don’t need notifying from, for example do you really need Groupon to tell you that there are new offers available for you or that you have ran out of doughnuts on The Simpsons: Tapped Out… I don’t think so. Turn off these in Settings > Notifications and you will save a bit of battery daily.
Close Down Your Apps
Kill your power hungry apps. Double-click the Home Button to activate the multitasking dock, hold your finger on an app to enter “jiggly” mode, and kill any apps that might be running in the background, especially things like Skype and TomTom navigation – as these applications are designed to run in the background.
Restore Your iPhone (Last Resort)
If you have tried all the above and your still having battery woes after a week or two. You could try restoring your iPhone to its factory settings, This can solve a lot of problems on Apple devices and if you go into an Apple Store this is one of the first things that they will tell you to do. Just make sure you have a current iCloud backup and plug your iPhone into iTunes – Click ‘Restore’ and watch go and make a cup of tea (Takes around 15 mins)
