Universal Search for battery alert app

[LakeLucerne]

I am searching for an app which can run in the background and would allow an iPhone or iPad to notify me when the battery has reached a defined charging state.

Thinking about giving away my current Android phone, a Google Pixel 4, for an iPhone 13 I search for an app which runs in the background and alerts me every time a configured charge level has been reached. On the Pixel 4 I have an app which does exactly that job.

On my iPad, I have installed an app called Battery Charge Alarm from Bastiaan Modderkolk which does the job if I activate it on each time I charge my phone. This isn't very convenient and inapplicable for my phone as I am a heavy (business) user and charge my phone several times during a day (in the office, in my car on the way to customers, at home, etc.) to hold the battery between 30% and 80%. No need to discuss this pattern in this thread. I drive a Tesla, own a degree in applied physics and know a lot about batteries. You can treat your battery as you like but for me it is crucial to have an app which works as described above.

As I am new in the iOS universe (I have the iPad 12.9 Pro for 3 months now) I would be very thankful if you could help me out in finding such an app or to clarify if that's impossible regarding the current architecture of iOS.

Best wishes from Switzerland

This can be done with the Shortcuts app. Create a new Automation, set 'Battery Level' as the trigger, use the slider to set a charge level, e.g. 80%, and select 'Rises Above 80%'. Tap 'Next' and then 'Add Action'. Tap 'Scripting', scroll down to the Notification section and specify an alert or notification. You can then enter the notification contents.
Create another automation using 'Battery Level' - 'Falls Below 30%' as a trigger.
These automations can run as background services.

I drive a BMW, own a degree in health science and don't know much about batteries

That's why I'm wondering why I should keep the battery between 30-80%, effectively using 50% of its capacity from the beginning. I keep the battery between 10-100% and I know it will degrade faster, but when its capacity decreases below 80% after 2 years of abuse, I can still use 70% which is more than the 50% you have been using.

I have tried to keep the battery between bounds because I can see why it's better, but I want/need to use the full capacity sometimes.

Dear Canaria

Many thanks for your post which is of great value for me (and saved my personal Android-2-iPhone project).

If you keep the battery between 20 and 80% a LiPo or LiIon battery will show only minimal degradation over years. As mentioned above, I heavily use a Google Pixel 4 for two years now and the battery shows nearly null degradation even being charged to 100% on rare occasions (e.g. backcountry snowshoe trips, mountainbiking etc. where I need the phone as an emergency device with maximum runtime).

In my normal daily routine I can charge my phone on several occasions and the alert helps me to stay in the range mentioned above without the need to concentrate on the charging progress.

Once again: many thanks for your helpful post and best wishes.
