Tecno or Infinix Alarm Not Going Off? 7 Fixes

If your alarm isn't going off on a Tecno, Infinix or itel phone, Phone Master has almost certainly stopped the alarm app in the background. Use Beyond Alarm, which opens Phone Master's auto-start list for you, then allow auto-start, turn off power saving for the app and lock it in Recents.

The short version:

• Use Beyond Alarm. On Tecno, Infinix and itel its reliability screen adds an Auto-start & Phone Master step that opens the right page, and it tells you the next morning if an alarm didn't ring.
• Phone Master on all three brands closes background apps and blocks auto-start, alarm apps included.
• Fix four things: Auto-start, power saving management, battery optimisation and a Recents lock.
• Turn off sleep mode optimisation if your phone has it.
• A silent ring is a different problem: check the Alarm volume and tone.

Why Tecno, Infinix and itel phones stop alarms

All three brands belong to the same company, Transsion, and run close relatives of the same software: HiOS on Tecno, XOS on Infinix, itel OS on itel. All three ship Phone Master, the tool that clears memory, boosts speed and saves battery.

Saving battery is the problem. dontkillmyapp.com, the long-running list of phone makers that stop background apps, says Tecno's "aggressive battery setting causes app to be completely halted, like frozen in time". An alarm app frozen at 3am can't wake up at 7.

Infinix, Tecno and itel phones are a large share of Beyond Alarm's Android users, which is why the app treats all three as one family and sends them to the same fixes.

Which symptom do you have?

Beyond Alarm: the checks done for you

We built Beyond Alarm's reliability screen because no app can read Phone Master's settings. What it can do is open the right screen and keep a list. On a Tecno, Infinix or itel phone it shows:

• Auto-start & Phone Master: "Phone Master → Auto-start management → allow Beyond Alarm. Then lock it in Recent apps so it isn't cleared." The button opens Phone Master's own auto-start list.
• Exact alarm, Notifications, Full-screen alarm and Battery optimization, each read automatically.
• Don't pause if unused, so Android doesn't put the app to sleep after a quiet few weeks.
• A link to the Tecno page on dontkillmyapp.com, in case your menus differ.

1. Allow auto-start in Phone Master

Auto-start lets an app start itself after a restart or after Phone Master has closed it. Without it, an alarm app that was cleared overnight stays dead.

dontkillmyapp.com gives the path as Phone Master → Toolbox → Auto-start management: allow your alarm app. A Salestrail guide for Infinix gives a second route on some models: Settings → Apps Management → More Settings → Auto-start Management. If neither matches, search Settings for "auto-start".

2. Turn off power saving management for the app

dontkillmyapp.com lists a second, separate switch: Settings → Battery Lab → Battery Saving Settings, then turn off Power Saving Management For Apps for your alarm app. Auto-start alone isn't enough if the battery manager still freezes the app once it's running.

3. Set battery optimisation to unrestricted

The standard Android setting is still there underneath. Long-press the alarm app, open App info → Battery, and choose Unrestricted (or "Don't optimise" on older versions). Beyond Alarm reads this one for you and shows it as Battery optimization on its reliability screen.

4. Lock it in Recent apps

Phone Master and the "clear all" button can both close an app that's sitting in Recents. Open Recent apps, find your alarm app and use its lock option so a clean-up leaves it alone. dontkillmyapp.com recommends the same.

5. Check Phone Master's night-time options

dontkillmyapp.com flags a few more Phone Master options worth a look:

Not every model has every option, and names move between HiOS and XOS versions. If your alarm fails only some nights, these are the usual suspects. For saver modes in general, see does your alarm work in battery saver mode.

6. Alarm permissions on Android 12 and later

Third-party alarm apps need permissions the built-in Clock gets automatically. Search Settings for each:

• Alarms & reminders (Android 12+), so the alarm fires at the exact time.
• Full-screen notifications (Android 14+), so the ring takes over the lock screen instead of arriving as a notification.
• Notifications, switched on for the app.

7. A ring with no sound

If the alarm screen appears but stays quiet, check the Alarm volume slider under Sound settings, which is separate from ringtone and media. A tone that was a downloaded song can also go silent if the file was moved. Why your alarm is too quiet on Android covers every cause, and Do Not Disturb has three ways of its own to mute an alarm.

What Beyond Alarm adds once it rings

Getting the alarm to fire is half the job. On Android, Beyond Alarm also:

• Re-arms after a restart, before you've unlocked the phone, so an overnight update doesn't wipe your alarm.
• Holds the Alarm volume at maximum while it rings, and keeps ringing until you dismiss it or finish one of its 11 wake-up missions.
• Shows a missed-alarm card. If an alarm's time passed with no ring, the home screen tells you the next morning, with a button to fix the settings.

Test it before you trust it

Set an alarm for three minutes ahead, then press clear all in Recents and run Phone Master's clean-up. Lock the phone and wait. If it rings after that, it'll ring in the morning.

Recheck after every system update, which can reset auto-start lists. Our general Android guide and the OPPO and realme checklist cover phones with similar battery managers.
