These 10 Secrets Will Double Your iPhone's Battery
All of us use iPhones a lot and we probably want its battery to last longer.
The most common battery drainers are the features that make smartphones so great: GPS that lets you post geotagged photos and call taxis, internet connections that let you stream HD YouTube on the go and apps that work in the background to alert you to everything from friend requests to your preferred airline's flash sale.
We know you love your smartphone and all its smart features. That's why our tips for saving your iPhone's battery power focus not on turning off these essential features but on using them more efficiently.
#9. How bad is your iPhone battery life really?
A quick way to check whether there really is a problem with the battery in your iPhone is to head over to Settings > General > Usage > Battery Usage to check your Usage and Standby times.
If your device is working correctly, the usage time should have have gone up by less than a minute, while the standby time should have gained five minutes. If you see more than a minute increase on the Usage time, something is stopping your phone from sleeping and you have a battery drain problem.
#8. What apps are using the battery
In iOS 8 you can see exactly which apps are the biggest battery drainers. Go to Settings > General > Usage > Battery Usage and scroll down to see which of your apps were the biggest battery guzzlers in the past 24 hours, or last 7 days.
Expect to see Facebook up the top, Safari also seems to be quite draining. But obviously there are also some frequently used apps which are the biggest battery drainers.
#7. Increase battery life: turn down brightness
Luckily you can save some battery life by adjusting the iPhone's brightness. A quick fix is to turn down brightness using the slider in Control Center, accessed by swiping up from the bottom of the display. Drag the brightness slider as far left as possible.
At full brightness, an iPhone 5 lasted 6 hours, 21 minutes while playing 720p video. When we set the screen to half brightness, the phone lasted 9 hours, 48 minutes. That's a huge difference.
#6. Save your battery: Auto-lock your iPhone
While the screen of your iPhone is on, you're consuming power, so make sure that your iPhone isn't awake when you don't need it to be. If you want to get the maximum battery life from your iPhone, set the Auto Lock to 1 minute.
Venture into Settings > General > Auto-Lock and set your iPhone to sleep after one minute of inactivity. This will provide a substantial improvement to battery life over time.
#5. Get more battery life by turning on Airplane Mode
One of the biggest drains of battery life is the antenna, because it's constantly checking for nearby cellular and Wi-Fi networks. Simply moving around with the phone in your pocket will drain its battery, as it moves from within range of one base station to another.
If don't need to access data, make, or receive, calls, and you don't require GPS (for maps) you could put the phone into flight mode and stop all use of the iPhone's antenna.
It's a good idea to enable Airplane Mode if you are in an area of low coverage as the iPhone will be working hard to power the antenna to maintain a data connection.
#4. Extend battery life by disabling Wi-Fi
If you still need a cellular connection but can live without Wi-Fi, you can disable Wi-Fi by swiping up to reveal Control Centre and tapping the Wi-Fi icon to turn it off. This will stop your phone from hunting around for Wi-Fi networks it could join.
There are a few situations where avoiding using Wi-Fi might stop battery drain. If the Wi-Fi signal is poor then your iPhone will require more power to transmit and receive data.
#3. Stop iPhone battery drain: Disable Bluetooth
Bluetooth is considered to be a battery-drainer. If you're not using it to connect to a speaker, headphones, or other accessory, or to use the new Continuity features in iOS 8, then switch it off.
Bluetooth is usually left ON after an iOS update is installed, so you may not even be aware that it is on. If it is, tap the Bluetooth icon to turn it off.
#2. Turn down iPhone volume
It might surprise you but the volume setting affects battery life too, so if you are playing music or other audio from your phone, turn it down using the volume buttons.
Of course you could save battery power by not playing music, or you could switch to headphones, which won't require as much power as the iPhone's internal speakers. Note that the music equaliser also takes up a surprising amount of power.
#1. Stop your iPhone vibrating
Head to Settings > Sounds and turn off both of the vibrate options, because your device rattling around like crazy when a slew of messages arrives drains the battery like nobody's business.
There are dozens of annoying jingles you can choose from to announce to the world that someone's just sent you a message without the accompanying vibration.
