How to Set a Daily Charging Reminder on Android

The clock-app approach

You can set a 10 p.m. alarm labelled "charge phone" in the Clock app. It works, but it rings every night whether the battery is at 9 percent or 90, so after a week you start ignoring it, which is the problem you were trying to solve.

A reminder that checks the battery first

Battery Call has scheduled charge reminders: pick a time, such as your bedtime, and a battery level. At that time the app checks the battery; if it is below the level and the phone is not charging, it rings with a full-screen call. If you already plugged in, nothing happens.

1. Open Battery Call and add a scheduled reminder.
2. Set the time (for example 22:30) and the level that counts as "needs charging" (for example 50 percent).
3. Choose the days it should run.
4. Allow exact alarms when the app asks; that is what lets it fire at the exact minute.

Combine it with the other alerts

• Add a full charge or 80 percent call for the morning, so the phone is not sitting at 100 percent for hours.
• Keep a low battery call for daytime.
• Use the unplug alarm when charging away from home.

Reliability checklist

Reminders depend on Android letting the app wake up: grant the alarms and reminders permission, exclude the app from battery optimisation, and allow autostart on brands that have it. Everything runs on the phone; the app never needs an account or an internet connection to ring.
