Medication reminder arrives late? Battery settings for Xiaomi, Samsung, Huawei and OnePlus

In short

Many Android phones stop apps in the background to save battery. A reminder then arrives late or not at all. Set Medifix to "No restrictions" once and it rings on time again. It takes about a minute.

Why this is needed

Makers like Xiaomi, Huawei, OPPO and OnePlus add their own power saving on top of plain Android. It stops apps you are not using, and with them any scheduled alarms. For a game that does not matter. For a tablet you are meant to take at a set time, it does.

Medifix schedules reminders as exact alarms so they ring even when the phone is asleep. During setup the app asks for the exact-alarm permission. The battery setting is the second half: it tells your phone to leave Medifix alone. We cannot change it for you, only you can in the system settings. That is why the app shows the matching steps for your phone under "Set up reliable alarms" when you start.

The steps for your phone

Names can differ slightly between Android versions. The idea is always the same: Medifix is allowed to run in the background.

  5. Choose No restrictions.

Samsung

  1. Open the Settings app and tap Apps.
  2. Tap Medifix.
  3. Tap Battery.
  4. Choose Unrestricted.

Huawei

  1. Open the Settings app and tap Battery.
  2. Tap App launch and find Medifix.
  3. Turn off automatic management.
  4. Turn on Auto-launch, Secondary launch and Run in background.

OPPO and OnePlus

  1. Open the Settings app and tap Battery.
  2. Tap App battery management and find Medifix.

Another phone

For other makers, Medifix opens the matching Android setting directly from the guide in the app.

How to check it worked

Set a test reminder for the next quarter hour, lock the phone and put it down. If it rings on the minute, you are set. If it does not, or arrives much later, go through the steps again and check that notifications are allowed for Medifix.
