Waking up late because your iPhone alarm failed you? You're not alone! It's a frustrating experience, but thankfully, often easily fixable. Before you blame gremlins, let's troubleshoot.
First, **double-check your volume!** Sounds simple, but easily overlooked. Even if your ringtone is loud, your alarm volume might be muted in Settings > Sounds & Haptics. Drag the volume slider up under "Ringtone and Alerts."
Next, **verify your alarm settings** in the Clock app. Is the time correct? Is the alarm toggled *on* (the slider should be green)? Is it set to repeat if you need it to?
**"Do Not Disturb" mode or "Sleep" Focus** can silence alarms. Temporarily disable these or customize them in Settings > Focus to allow alarms.
Finally, an **outdated iOS** can sometimes cause glitches. Update to the latest version in Settings > General > Software Update.
If none of these solutions work, try deleting and recreating the alarm. If *that* fails, consider a factory reset (back up your iPhone first!). Don't let a faulty alarm ruin your day!
