iPhone Keyboard: Always Show Uppercase Keys

To make the iPhone keyboard always show uppercase letters on the keys, go to Settings > General > Keyboard and turn off the “Show Lowercase Keys� switch. With that setting disabled, the keyboard displays capital letters on every key at all times, regardless of whether Caps Lock is on or off. This article explains why the setting exists, how it works, and what to do if the keyboard still looks lowercase.

What “Show Lowercase Keys� Actually Does

The “Show Lowercase Keys� toggle, introduced in iOS 9, changes the letter labels on the on-screen keyboard. When the setting is on (the default), the keyboard shows lowercase letters (a, b, c) when you’re typing in lowercase, and uppercase letters (A, B, C) only when Caps Lock is active or when you’re typing at the start of a sentence. When the setting is off, the keyboard always displays uppercase letters on the keys, even when the text you type will be lowercase.

This is purely a visual preference—it does not affect what characters are actually typed. The letters that appear on the keys are just labels; the actual output is determined by the Shift key and Caps Lock state.

Why Apple Added the Lowercase Option

Apple introduced the lowercase key labels to help new users, especially those switching from physical keyboards, understand which case they are about to type. The lowercase display acts as a visual cue: if you see lowercase letters, you know the next character will be lowercase; if you see uppercase, you know the Shift key is active. Many users, however, find the lowercase labels harder to read, particularly in low light or with larger text sizes, and prefer the classic all-caps look. The setting gives you that choice.

How to Turn Off Lowercase Keys (Step by Step)

Open the Settings app on your iPhone.
Tap General.
Scroll down and tap Keyboard.
Find the “Show Lowercase Keys� toggle.
Turn the switch off (it will turn gray).

That’s it. The change applies immediately—no restart needed. Open any app that uses the keyboard (like Messages or Notes) and you’ll see uppercase letters on all keys.

What If the Keyboard Still Shows Lowercase?

If you turned off “Show Lowercase Keys� but the keyboard still displays lowercase letters, check the following:

Restart the app—some apps cache the keyboard appearance. Fully close the app and reopen it.
Check if you’re using a third-party keyboard—the setting only affects the built-in Apple keyboard. If you’re using Gboard, SwiftKey, or another third-party keyboard, that keyboard has its own appearance settings. Look for a theme or appearance option within that keyboard’s settings.
Update iOS—older iOS versions may have bugs. Go to Settings > General > Software Update to see if a newer version is available.
Restart your iPhone—a simple restart can clear temporary glitches.

Related Keyboard Settings You Might Want

While you’re in Keyboard settings, you may also want to adjust:

Auto-Capitalization—automatically capitalizes the first letter after a period. If you prefer all lowercase, turn this off.
Caps Lock—enables Caps Lock by double-tapping the Shift key. If you want to type in all caps easily, make sure this is on.
Key Flicks—on iPads, this lets you type numbers and symbols by swiping down on keys. Not available on iPhone.

Common Misconceptions

One common misunderstanding is that turning off “Show Lowercase Keys� will make the keyboard type in uppercase. It does not. It only changes the label on the keys. If you want to actually type in uppercase, you need to enable Caps Lock or hold the Shift key. Another misconception is that the setting is hidden or requires a special trick—it’s always been in the same place since iOS 9, though Apple has moved some keyboard settings around in later versions. In iOS 16 and later, the path is still Settings > General > Keyboard.

Frequently Asked Questions

Why did my keyboard suddenly show lowercase letters?

This usually happens after an iOS update or when you restore from a backup that had the setting enabled. The default is “Show Lowercase Keys� on, so if you never turned it off, it will stay on. Check the setting and turn it off again if you prefer uppercase.

Does this setting affect the iPad keyboard?

Yes, the same setting works on iPad. However, the iPad’s keyboard has additional options like “Key Flicks� and “Split Keyboard� that are separate. The uppercase/lowercase toggle behaves the same way.

Can I make only certain keys uppercase, like numbers or symbols?

No, the setting applies to all letter keys. Numbers and symbols are always shown as their standard characters (e.g., 1, 2, !, ?) regardless of the setting. The toggle only affects the 26 letter keys.

Will turning off lowercase keys drain my battery?

No. The keyboard display is rendered by the system, and changing the label text has no measurable impact on battery life. It’s purely a cosmetic change.

I turned off the setting but it keeps coming back on. What’s wrong?

This can happen if you have a configuration profile or an MDM (mobile device management) restriction on your iPhone, often from a work or school account. Check Settings > General > VPN & Device Management. If you see a profile that restricts keyboard settings, you may need to remove it or contact your administrator.

Does this work on iOS 18?

Yes, the setting is still present in iOS 18. The path remains Settings > General > Keyboard > Show Lowercase Keys. If you can’t find it, make sure you’re looking at the built-in keyboard settings, not a third-party keyboard’s settings.

General steps for current mainstream versions; menus can differ by device and version. See the disclaimer or report an error.
