How to get the battery temperature details in iOS?

I am getting battery status and others .

UIDevice *myDevice = [UIDevice currentDevice];
[myDevice setBatteryMonitoringEnabled:YES];
float batLeft = [myDevice batteryLevel];
int i=[myDevice batteryState];

int batinfo=(batLeft*100);

NSLog(@"Battry Level is :%d and Battery Status is :%d",batinfo,i);

switch (i)
{
    case UIDeviceBatteryStateUnplugged:
    {

        break;
    }
    case UIDeviceBatteryStateCharging:
    {

        break;
    }
    case UIDeviceBatteryStateFull:
    {

        break;
    }
    default:
    {

        break;
    }
}

Now i am trying to get the temperature details is it possible to get the battery temperature from device .

if you don't need temperature number then it is useful to use ThermalState api

Brother I gone through the answer for your question and which indicates that you can get and generally it shows the following states

Battery design capacity
Battery current raw capacity (in mAh)
Battery cycle count
Current battery temperature
Current battery voltage
Current battery discharge rate (device power consumption), in mA

Also following shows the results of battery

{
AdapterDetails =     {
    Amperage = 1000;
    Description = "usb host";
    FamilyCode = "-536854528";
    PMUConfiguration = 1000;
    Watts = 5;
};
AdapterInfo = 16384;
Amperage = 1000;
AppleRawCurrentCapacity = 1279;
AppleRawMaxCapacity = 1275;
AtCriticalLevel = 0;
AtWarnLevel = 0;
BatteryData =     {
    BatterySerialNumber = REDACTED;
    ChemID = 355;
    CycleCount = 524;
    DesignCapacity = 1420;
    Flags = 640;
    FullAvailableCapacity = 1325;
    ManufactureDate = REDACTED;
    MaxCapacity = 1273;
    MfgData = REDACTED;
    QmaxCell0 = 1350;
    StateOfCharge = 100;
    Voltage = 4194;
};
BatteryInstalled = 1;
BatteryKey = "0003-default";
BootBBCapacity = 52;
BootCapacityEstimate = 2;
BootVoltage = 3518;
CFBundleIdentifier = "com.apple.driver.AppleD1815PMU";
ChargerConfiguration = 990;
CurrentCapacity = 1275;
CycleCount = 524;
DesignCapacity = 1420;
ExternalChargeCapable = 1;
ExternalConnected = 1;
FullyCharged = 1;
IOClass = AppleD1815PMUPowerSource;
IOFunctionParent64000000 = <>;
IOGeneralInterest = "IOCommand is not serializable";
IOInterruptControllers =     (
    IOInterruptController34000000,
    IOInterruptController34000000,
    IOInterruptController34000000,
    IOInterruptController34000000
);
IOInterruptSpecifiers =     (
    <03000000>,
    <26000000>,
    <04000000>,
    <24000000>
);
IOMatchCategory = AppleD1815PMUPowerSource;
IOPowerManagement =     {
    CurrentPowerState = 2;
    DevicePowerState = 2;
    MaxPowerState = 2;
};
IOProbeScore = 0;
IOProviderClass = AppleD1815PMU;
InstantAmperage = 0;
IsCharging = 0;
Location = 0;
Manufacturer = A;
MaxCapacity = 1275;
Model = "0003-A";
Serial = REDACTED;
Temperature = 2590;
TimeRemaining = 0;
UpdateTime = 1461830702;
Voltage = 4182;
"battery-data" =     {
    "0003-default" = <...>;
    "0004-default" = <...>;
    "0005-default" = <...};
"built-in" = 1;
}

Above things are from UIDeviceListener

I run with sample code I got below temparature

enter image description here

enter image description here

in EEPowerInformation.m class I put the breakpoint and check that.It is called and brings all information about battery.

- (void) listenerDataUpdated: (NSNotification *) notification
{
  latestPowerDictionary = notification.userInfo;
  NSLog(@"The latest Power Dictionary is - %@",latestPowerDictionary);
  NSLog(@"The battery Temperature is - %@",[latestPowerDictionary objectForKey:@"Temperature"]);
  if (self.delegate != nil)
    [self.delegate powerInformationUpdated: self];
}

The Printed Statements are

The latest Power Dictionary is - {
AdapterDetails =     {
    Amperage = 1000;
    Description = "usb host";
    FamilyCode = "-536854528";
    PMUConfiguration = 970;
    Watts = 5;
};
AdapterInfo = 16384;
Amperage = 1000;
AppleChargeRateLimitIndex = 0;
AppleRawBrickIDVoltages =     (
            (
        39,
        420
    )
);
AppleRawCurrentCapacity = 1084;
AppleRawExternalConnected = 1;
AppleRawMaxCapacity = 1221;
AtCriticalLevel = 0;
AtWarnLevel = 0;
BatteryInstalled = 1;
BatteryKey = "0003-default";
BootBBCapacity = 673;
BootCapacityEstimate = 29;
BootVoltage = 3810;
CFBundleIdentifier = "com.apple.driver.AppleARMPlatform";
ChargerConfiguration = 900;
CurrentCapacity = 1222;
CycleCount = 343;
DesignCapacity = 1430;
ExternalChargeCapable = 1;
ExternalConnected = 1;
FullyCharged = 0;
IOClass = AppleARMPMUCharger;
IOFunctionParent5E000000 = <>;
IOGeneralInterest = "IOCommand is not serializable";
IOMatchCategory = IODefaultMatchCategory;
IONameMatch = charger;
IONameMatched = charger;
IOPowerManagement =     {
    CapabilityFlags = 32832;
    CurrentPowerState = 2;
    DevicePowerState = 2;
    MaxPowerState = 2;
};
IOProbeScore = 1000;
IOProviderClass = IOService;
InstantAmperage = 198;
IsCharging = 1;
Location = 0;
Manufacturer = A;
MaxCapacity = 1300;
Model = "0003-A";
Temperature = 3120;
TimeRemaining = 67;
UpdateTime = 1470665642;
Voltage = 4188;
"built-in" = 1;
}

Finally the Printed result of battery Temperature is

The battery Temperature is - 3120

That is not possible and there is no public API to find . but I found the some answers in here May be it helps you , see once. But some private API you can get this details.

sample app you cannot use this if you deploy your app on the Apple Store, but it can be useful when deploying to TestFlight
