You can take a screenshot.
From saving content you view on your mobile browser to taking quick
snaps of funny texts, taking a screenshot can be incredibly useful in a
lot of ways. Taking a quick snap of whatever is on your iPhone’s display
is super quick and easy; simply press the home key at the bottom of
your phone at the same time as the button at the top of the device. Your
screenshot will be saved to your camera roll.
Have Fun With Siri
If you add the address for people in your contact list and then ask Siri
to take you to them, she will give you directions to their house.
Telling Siri about your relations will cause her to ask to remember
them. If you agree, she will remember. Then, whenever you ask her to
name your relation, she will. e.g. Telling Siri that Rebecca is my
sister will make her tell that Rebecca is your sister whenever you ask
the question, "Who is my sister?"
Instant Scrolling
If you have scrolled down a really long web page, then just tap the bar
on the top of your screen to immediately be taken to the top of it.
Automatic Backup
To automatically backup your iPhone on iCloud, go to Settings >
iCloud > Storage & Backup and turn on iCloud Backup. This will
automatically backup your phone's critical data without the need to
synchronize it again and again.
Caps Lock
To type in capital letters, just enable Caps Lock on your phone by double tapping the Shift arrow.
Extend Battery Life
If you feel that your iPhone's battery performance is below par, you can increase it by disabling 3G, Bluetooth and push notifications. Just go to Settings> General> Network to do this.
Use the Home Button
Pressing the Home button once will take you to your Main Screen.
Pressing it twice will take you to Spotlight Search which you can use to
search everything on your phone.
Control what appears in Spotlight search
To control what appears in Spotlight search, go to Settings> General> Spotlight Search and select according to your needs.
Block Inappropriate Content
To do so, go to Settings> General> Restrictions and tap Enable
Restrictions. This will allow you to add a pass code and select which
apps you want to make accessible.
Download Apps and Music on all your iProducts
If you have many Apple devices and don't want to download the same apps
or music on them again and again, you can enable automatic downloads for
apps, music and iBooks by going to Settings> Store.
You can be a master of autocorrect.
If you are typing a note or an e-mail, you may have had some issues with
the iPhone’s autocorrect or autocomplete features. Sometimes the
results from this feature are helpful and right on, but other times they
are anything but helpful. If you pay attention when you type, you don’t
have to be at the mercy of your iPhone.
A little textbox will pop up and recommend a spelling or a completed
word; to accept it press the space key. If you don’t want to accept the
word, tap the tiny “x” that appears next to it. This can help you avoid
some faux pas when texting.
Create your own dictionary.
Speaking of autocorrect and autocomplete, you can create your own
dictionary. When you enter a custom dictionary, your phone will
autocorrect and autocomplete the things you type by inserting words you
actually use. To do this, go to “Settings” and then “General.” In this
menu, scroll down to the shortcuts area and tap “Add New Shortcut.” Not
only will this let you enter in custom dictionary words, but you can
also enter in shortcuts so that your abbreviations will end up inputting
complete words in texts and emails.
Have custom ring tones for less money.
Your iPhone comes with many ringtones and message tones, but these are
the same sounds that millions of other iPhone users are utilizing. If
you want something unique, you may be tempted to shell out big bucks for
custom ring tones. If you like to assign special ringtones to certain
people or groups, this may cost you a lot. So, in order to get ringtones
without breaking the bank (and taking away your app budget), you should
look at applications that allow you to make ringtones out of songs you
already have on your phone. Some of these cost money and should only be
bought if you want to create a lot of ringtones. If you are only looking
to turn out a couple of tones, you can even get a free version of these
popular apps.
Block your number from other people’s caller ID.
Blocking your number can be helpful for any number of reasons. Maybe you
don’t want an ex that you need to call to have your new number, or
possibly you are using your personal number for business, but you don’t
want professional contacts to have your personal digits. You can block
your number easily from the “Settings” menu. There, you should go to the
“phone” area and select the “Show My Caller ID” option; there you need
to slide over to “no.” To switch it back on, follow the same steps and
slide over to “yes.”
