Accessing the battery level on your iOS device
I recently saw a question on our forums on how to access the current battery level on an iOS device using FireMonkey, so I thought I would do a quick post about it. This sample code extends the DeviceInfo code snippet included with RAD Studio 10.1 Berlin Anniversary Edition.
unit uMain; interface uses System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants, FMX.Types, FMX.Controls, FMX.Forms, FMX.Dialogs, FMX.StdCtrls, FMX.ListBox, FMX.Layouts, FMX.Controls.Presentation; type TDeviceInfoForm = class(TForm) btnGetDeviceInfo: TButton; ListBox1: TListBox; lbOSName: TListBoxItem; lbOSVersion: TListBoxItem; ToolBar1: TToolBar; Label1: TLabel; lbDeviceType: TListBoxItem; lblBatteryLevel: TListBoxItem; procedure btnGetDeviceInfoClick(Sender: TObject); private { Private declarations } public { Public declarations } end; var DeviceInfoForm: TDeviceInfoForm; implementation {$IFDEF IOS} uses iOSapi.UIKit, iOSapi.Foundation, Macapi.Helpers; {$ENDIF} {$R *.fmx} {$IFDEF IOS} procedure TDeviceInfoForm.btnGetDeviceInfoClick(Sender: TObject); var Device : UIDevice; begin Device := TUIDevice.Wrap(TUIDevice.OCClass.currentDevice); lbOSName.Text := Format('OS Name: %s', [NSStrToStr(Device.systemName)]); lbOSVersion.Text := Format('OS Version: %s', [NSStrToStr(Device.systemVersion)]); lbDeviceType.Text := Format('Device Type: %s', [NSStrToStr(Device.model)]); //code added for detecting battery level Device.setBatteryMonitoringEnabled(True); lblBatteryLevel.Text := Format ('Battery Level: %d', [Round(Device.batteryLevel*100)]); end; {$ENDIF} end.

I don't think that's possible, but I have not really looked into it. https://developer.apple.com/documentation/uikit/uidevice/1620042-batterylevel might be helpful.

I also know the same question how I can access the battery level in IOS system? I also contact to the iPhone app development company but they do not reply me of my question.
I was posted this question on the many forums and question answering site like quora or ask but no one gives me the proper answer to my question, then suddenly I jump it to on your site and I found the answer to my question. I really thankful to share this stuff on your website. https://www.ingic.ae/ios-app-development/ -
