iPhone Tips & Tricks Worth Learning
Section updated .
The iPhone tips worth learning are the ones you use every day without thinking — not obscure toggles you will forget by Thursday. Four areas repay the effort: camera controls that get the shot before the moment passes, Messages habits that cut back-and-forth, keyboard tricks that remove repeated typing, and a Photos routine that stops a 40,000-image library becoming unsearchable. Everything here is built into iOS with no extra apps.
Most “hidden iPhone feature” lists fail for the same reason: the features are genuinely hidden, which is another way of saying you will never remember them. A tip only pays off if it attaches to something you already do many times a week.
So these four guides are organised by app rather than by novelty. Each tip states the friction it removes and how you will notice the difference, and anything that only helps once is left out.

iPhone camera tips that get the shot
Launch faster from the lock screen, lock focus and exposure, use burst and Live Photos, and fix a blurry habit.
Read the guide →Messages tips that cut back-and-forth
Pin conversations, reply inline in group threads, search properly, use Check In, and unsend a message you regret.
Read the guide →Keyboard and text tips that stick
Text replacement, trackpad cursor, three-finger undo, scanning documents, and selecting text without the fight.
Read the guide →Keep a Photos library you can search
A ten-minute monthly routine using Duplicates, Recently Deleted, albums, and search that people actually keep up.
Read the guide →How to work through this section
Learn one tip per app per week rather than twenty in one sitting. Start with the camera, because photos are the most common thing people wish they had done better and the wins are immediate. Add Messages next, since it is the app most people open most often. Keyboard tips compound quietly — a text replacement you set up once saves a few seconds thousands of times. Finish with the Photos routine, which is maintenance rather than a trick, and is what keeps the camera wins usable a year later.
Frequently asked questions
What is the fastest way to open the iPhone camera?
Swipe left on the lock screen, or press and hold the camera button in the lock screen corner. Both work without unlocking, which is what matters when the moment is about to pass.
Can I unsend an iMessage?
You can undo sending a message for a short window of about two minutes after sending, by touching and holding the message and choosing Undo Send. It only works when both people are on recent iOS versions using iMessage, not SMS.
What is text replacement on iPhone used for?
It expands a short trigger you type into a longer phrase, so a few characters can produce an email address, a home address, or a standard reply. It is set up once in Settings under Keyboard and then works in every app.
How do I delete duplicate photos on an iPhone?
The Photos app detects duplicates and collects them in a Duplicates album under Utilities, where you can merge them individually or all at once. Merging keeps the highest quality version and the combined metadata.
Do these tips work on older iPhones?
Most do, because they rely on long-standing iOS features rather than new hardware. A few, such as the Action button or Camera Control, depend on specific recent models, and those are noted where they appear.
