1. Shake to undo :
Make a mistake while typing or editing a picture? No worries! Just give your phone a little shake—like you’re making a martini— and it’ll ask you if you’d like to undo the action. Cheers!
2. Recharge your battery faster by switching to airplane mode :
Switching to airplane mode turns off battery-draining wireless and cellular access, allowing your phone to recharge up to twice as fast.
3. Get Siri to read your emails aloud for you :
Just say the magic words “Read my email” and Siri will read all your messages aloud to you. If you like, you can tell her to read only your most recent email (“Read my latest email”) or just those from a specific contact (“Do I have email from Mark?”).
4. Find out which planes are flying overhead :
Just ask her: “What flights are above me?” Or you can be even more blunt and just say, “Planes overhead.” Boom! She”ll bring up a list that shows all the flights above you at that moment. Why you would ever need this I have no idea, but it’s pretty rad anyway.
5. Teach Siri how to pronounce words :
The best part about this is that it makes you feel smarter than Siri. Whenever Siri mispronounces something, just tell her, “That’s not how you pronounce [BLANK]” and she’ll offer you alternatives. You can then select the best one.
6. Automatically turn off your music with the timer :
7. Scroll through videos and music at half, quarter, or eighth speed :
This one is super useful. When you scroll—or as Apple calls it, “scrub”—through a movie or a song, the default mode is high-speed scrolling. This sometimes makes it hard to find the exact spot you want. But you can control the rate at which you scroll. To do this, hold down the dot—or “playhead”—in the scrollbar at the top of the video screen (tap the screen to display the scrollbar if it isn’t visible) and slide your finger straight down without lifting it. This allows you to change the scrubbing speed to half-speed, quarter-speed, eighth-speed (“fine scrubbing”). Once you’ve selected the speed, move your finger left or right (without lifting it) to scroll.
8. Take a photo with the volume buttons :
9. Take multiple photo bursts all at once :
10. Reveal timestamps on text messages :
Drag the text bubble to the left and you’ll see a timestamp for every text message. Among other things, this will show you just how much time you waste texting.
11. Use your iPhone as a level :
12. Make your iPhone speak selected text :
13. Start a new sentence just by double-tapping the spacebar :
14. See a more detailed calendar :
15. Lock autofocus and exposure while taking a picture :
16. Add web suffixes with a single tap :
17. Quickly access your email drafts :
18. Customize vibrations :
19. Create custom keyboard shortcuts :
20. Create a passcode with letters (not just numbers) :
By default, your iPhone asks you to type in numbers when you create the passcode that unlocks your phone. But you can change this setting. Go to Settings > General > Passcode Lock and turn off “Simple Passcode.” You will be prompted to change your passcode, and a full keyboard will appear onscreen instead of just the number pad. This keyboard will pop up every time you unlock your phone.
21. Set your phone to emit light flashes for alerts :
22. It tracks every location you’ve been to :
23. Its performance is more customizable than you think :
Have an iPhone 4S and sick of all the stutters caused by iOS7? Go to settings, general, accessibility, and turn on the “reduce transparency” option located under “increase contrast.” Also, turn off “reduce motion.” Now, your iPhone should run about as well as it did under iOS6, with all of the software upgrades of 7.
24. It can work without a power button :
Go to settings, general, accessibility, and turn on “AssistiveTouch” if your power button ever breaks. It’ll project a small icon onto the screen that’ll allow you to lock your phone without the need of a physical button! You can also turn your phone off using this as well. Don’t worry, even without a power button your phone will automatically turn on when you plug it in.
25. You can set your phone to perform certain actions when triple clicking the home button :
26. You can close more than one app at a time :
When I upgraded to iOS7, I found the app-closing procedure to be an annoying and time consuming process. No longer! Turns out you can close multiple apps at a time by swiping up with two or three fingers.
27. It can replace your leveling tool :
Ever wish you had a level around to get those perfectly straight edges you’ve always dreamed of? Well wish no more! Your iPhone’s compass has a hidden level (ha, get it?) that you can activate by swiping to the left.
28. Its battery lasts forever on airplane mode :
29. Its performance improves when you clean its hard drive.
Always try to leave at least two gigabytes free on your iPhone. Anything less and it will start to slow down considerably.
30. It tracks popular apps near your location :
There’s a little innocuous option located at the bottom of the app store called “Near Me” that’ll literally show you the most popular apps in your immediate area. Usually these will include local news apps or bus schedule apps for the town you’re in. Useful if you are in a new area.
31. It can tell you exactly when you received a text message.
32. It can change Siri’s gender :
Tired of the same old Siri? Go to settings, general, Siri, and scroll down to “voice gender.” Here you can give Siri a male voice.
33. Spotlight search is actually…useful? :
I never see anybody use spotlight search for anything, but in reality it’s quite a useful feature. Just swipe down on your homescreen to access it, and type in whatever you need. It’s more efficient to search for contacts or a certain song here than it is to open up individual apps and scroll through a hundred names or titles.
34. It has a built in back button.
35. It can appease your impeccable grammar standards.
36. It can delete your mistakes with a simple shake :
Make a typo? Apply the wrong filter to a photo? Just shake your phone, and much like an etch-a-sketch, or control-Z on a PC, it’ll erase the last thing you did.
37. It charges faster if you use a power adapter supposedly meant for the iPad :
38. If you want to listen to music or audiobooks before you go to sleep, set a timer so it turns off :
Launch your Clock app with a tap, and then tap on the Timer button in the lower right. Once there, set the timer for however long you want your media to play. Next, tap “When Timer Ends,” and scroll down to the bottom. Tap on “Stop Playing.” Now, when your music will stop playing when the timer runs out.
39 . You can control the scrubbing rate of video and audio by moving your finger down the screen as your scrub through it.
40. Use your iPhone as a level. Just swipe left :
