1/ Check your iPhone battery percentage from macOS Sierra — If you are an iOS user who also has a Mac, making sure your Mac and iPhone are both using the same iCloud account and you have Bluetooth enabled, you can hold down the Option key on your Mac’s keyboard and click the Wi-Fi icon in the Mac menu bar. After a second or so, your iPhone will show up in the Personal Hotspot section even if you’re not using it to set up a personal hotspot.
If you’re not using it as a personal hotspot, that option will be in light grey; if you are using the iPhone for that purpose, Personal Hotspot will be in bold letters. either way, the battery icon and signal strength is displayed (left).
However, if you mouse over your iPhone’s line, a small menu will appear that shows the exact percentage of battery you have left (below).
2/ Individual Read Receipts in Messages — You can turn on read receipts in Messages for just one contact. If you tap the information button (an “i” with a circle around it at top-right of your screen) you’ll see the option to enable read receipts just for that person.
3/ Take screen shots on iPhone and iPad — The ability to quickly snap a photo of whatever’s on your iPhone’s (or iPad’s) screen. It’s handy for everything from documenting buggy iOS apps to quickly sharing a text message thread with a friend.
Just press the Sleep/Wake (on the top right of your iPhone/iPad) and the Home button (the dished button at bottom centre of your screen) at the same time. The screen will flash and you’ll hear a telltale camera snap, then find your screenshot sitting in the iOS Photos app’s Screenshots album or in your Camera Roll. From there, you can share it by tapping the Share Sheet button (the square button with the upward arrow).
4/ Pinch-and-zoom to enlarge stickers — You can actually adjust how large or small stickers are before you send them: when you’re peeling a sticker off to put it somewhere in your conversation, add a second finger and pinch-to-zoom. This way you can make it bigger or smaller before you drop it into the chat.
5/ Unfreeze a frozen iPhone — It’s winter here but hey, this can happen in summer too. Sometimes your iPhone may come to a grinding halt, perhaps because of an errant app, or maybe iOS itself has locked itself up for some reason. Generally speaking, quitting a frozen app (by double-clicking the Home button, then swiping up on the app’s multitasking card that appears) is enough to fix the problem. You could also try a standard restart (press and hold the Sleep/Wake button until the “slide to power off” slider appears).
But if an app remains stubbornly stuck—or, worse still, if iOS becomes completely locked up—there’s another way to get things moving again: by force restarting your iPhone (a.k.a., a “hard” reset).
On pre-iPhone 7 models: Press the Sleep/Wake and Home buttons—but instead of letting them go immediately as you would when taking a screenshot, keep holding them until the screen goes blank. In a moment or so, you should see the Apple logo, a sure sign that your iPhone (or iPad) is rebooting itself.
On iPhone 7 or iPhone 7 Plus: Press and hold the Sleep/Wake and volume-down buttons until you see the Apple logo.
