Keeping these iPhone, iPad or iPod touch’s battery saving tips will go a long way. They are very helpful!!
Turn Auto-Brightness ON
The iPhone’s/iPad’s auto-brightness feature has been on every model since the Smartphone was introduced by Apple in 2007. It detects the lightening conditions around the phone and adjusts the brightness. Darker with dark light and brighter with brighter light. To turn on the Auto-Brightness, go to Settings –> Brightness –> Auto-Brightness slide the button from Off to ON.
Reduce screen brightness
Having higher brightness consumes the phone’s battery. To improve battery life, adjust the brightness to a desired amount that comfortably suits your eyes. To do so, go to Settings –> Brightness. Slide to left for lower brightness and to right to increase brightness.
Turn some sounds off
Sounds use up battery life too, and there are some sounds on the phone that are not needed to operate the phone to its full potential. Go to Settings –> Sounds, all the way down you will find Lock Sounds and Keyboard Clicks. Turn them OFF.
Quitting Apps in Multitasking Queue
Once you open any app, even if you press the Home button and close it, it continues to run in the background. Completely closing these apps save a lot of battery as these apps keep draining your battery life. To close these apps completely, double press the Home Button and on the apps displayed, press any app till it starts shaking. Hit the minus button till the queue clears.
Turn Bluetooth OFF
Bluetooth is useful if you are using it with your wireless headsets, earpieces or your car Bluetooth connectivity. If Bluetooth is on it keeps transmitting data wirelessly even if you are not currently using it. TO turn off Bluetooth go to Settings –> General –> Bluetooth –> OFF
Keep WiFi OFF
Phone can be connected to a wifi to get access to internet without using your cellular data. But if there is no hotspot around and your wifi is on, the device keeps searching for any available network around. This drains the battery out, so unless you have an available wifi network around keep wifi off. Go to Settings –> WiFi –> OFF
Turn Location Services OFF
iPhone/iPad has a feature of built-in GPS. This allows the phone or other apps to use your current locations. Some of the apps that use location services are Maps, Find My Phone, Facebook, etc. If you are not currently using it its advisable to turn it off to save battery. Go to Settings –> general –> Location Services –> OFF
Turn Data Push OFF
You can configure your emails in the iPhone/iPad, which lets you download, check, reply and delete directly from the phone. Pushing your emails to the phone as soon as you receive an email requires the phone to connect to email server every now and then, draining battery and raising your cellular data usage. Go to Settings –> Mail, Contacts, Calendar –> Fetch New Data –> OFF
Fetching email on your phone requires the phone to access the email network which uses the battery up, the less often you fetch the lesser battery is used up. You can set it up for the longest time option or even select manually if you don’t have any important emails coming up.
Go to Settings –> Mail, Contacts, Calendar –> Fetch New Data –> Select best suitable preference
After you are done using the phone you press the home button, but the phone still remains lighted up. The on state of phone uses battery, but there is a feature for auto locking the phone. Select the shortest time to save battery; you can also lock manually before the auto lock turns on. To auto-lock go to Settings –> General –> Auto-Lock –> Select best suitable preference
