Use Push Notifications Only for the Most Important Apps

Seriously, Not every app needs to push its notifications; every single bit of push takes up battery power.

[tagline]Push Notifications on lock screen takes up much more power than you can actually anticipated for. Every time a push notifications opens the screen for a while, it uses the battery to light up the display. The more notifications on lock screen, the more you will lose battery life. Get a hold of it.[/tagline]

Go to Settings > Notifications and scroll down to the Include section. Then disable the Apps you don’t need push notifications. Flick the switch to OFF beside the app name to do that.

Disable Mobile Data and Wi-Fi when You are Not Using it

When you are outdoor; your iPhone or iPad will constantly be switching from LTE to 3G and even to Edge depending on your network signal. Controlling mobile data settings can improve battery life by good scale. There is a few things to do when dealing with Wi-Fi/Mobile Data. Here is some points for you to take out.

  1. If you are already connected to a Wi-Fi network (at office for example). Go to Settings > Cellular. You can turn the Cellular Data switch to OFF. The phone will stop looking for mobile data and will save some battery life there. 4G LTE uses some battery power too, turn the LTE switch to OFF if you are willing to run under 3G connection.

Make a Healthy Battery Charging Habit

You should get a proper habit of charging lithium ION batteries. Get a charging cycle and keep a good practice of charging your phone or iOS device.

“Battery life” is the amount of time your device runs before it needs to be recharged. “Battery lifespan” is the amount of time your battery lasts until it needs to be replaced. Maximize both and you’ll get the most out of your Apple devices, no matter which ones you own. (cited from Apple.com)

  • You can charge when the battery falls down to 50% or less.
  • Keep it away from extreme temperatures.
  • Store it half-charged when you store it long term.

Learn the best habits and maximizing performance for your device’s battery.

Do tell me if you have any other ideas on your mind about saving battery life without sacrificing too much of the functionalities.
