Turn Off Vibrations

A lot of energy is used to produce vibrating alerts. There is an actual motor, a physically moving part, which consumes electricity. Turning off vibrations can preserve battery life. Consider lowering your ring tone volume (using the volume buttons on the side of your device) instead of relying on vibrations. The vibrating alert does make noise, so a quieter ring tone is a good substitute. You can turn off vibrating alerts from Settings > Sounds. I would not recommend this for the corporate user who is in a lot of meetings. Even though the vibration makes noise, it is conventionally accepted. A quieter ring tone will be considered disruptive, even if the volume is comparable to a vibrating alert.

Close Unused Apps

Open iOS apps go dormant as the system frees up resources to run other apps. For the most part, you don’t need to actively close apps, as iOS will manage resources for you. There are some apps that run in the background when open. Even when they go dormant, a background thread still runs and updates the app. This is different from Background App Refresh, which updates closed apps.

To close apps, simply double tap the home button (or swipe four fingers up on the iPad) to display the multitasking view. Close apps by swiping them upward. You can even uses two or three fingers at a time to close multiple apps simultaneously.

Survival Mode

You can dramatically extend your iPhone’s battery life by going into survival mode. This is a practice, not a software setting. Simply power down your iPhone (hold the sleep/wake button and swipe “slide to power off”) and power it back up only when you need it. Make sure to turn the brightness all the way down and turn off Auto-Brightness. In this scenario, you want to use the least amount of power possible.

This practice works well if you are camping or traveling without a charger. Any calls you receive will roll over to voicemail. Of course, you must limit the frequency of powering up your iPhone as well as limiting overall use. If you’re powering up your iPhone 20 times a day, you’re better off just leaving it on. Using this survival mode practice, I was able to get my iPhone to last two weeks before it ran out of juice.

All of these battery life tips, when taken together, will dramatically improve your iPhone’s electrical stamina. I personally do not use all of these. A lot of these battery-consuming features are useful. Alter the settings as appropriate, and you will see improvements. That said, even with all of the battery-draining features, an iPhone can often go for two or three days without a charge. I have employed some of these tips, and I charge my iPhone about once in 4-5 days. The iPhone has a great battery and iOS is designed to make the most of it. These tips will help you squeeze as much battery life out of your device as possible. For further information about lithium-ion batteries, check out this article.
