If I sum the freeMemory and usedMemory the result is never the total available RAM.
For example, on my iPhone 5c, it says I have 30mb free and 440mb used.

I have tried various ways to measure memory usage (different code snippets from around the web) and each has a different result (Including the method you supply)

Do you have any insight?

vm_size_t usedMemory(void) {
    struct task_basic_info info;
    mach_msg_type_number_t size = sizeof(info);
    kern_return_t kerr = task_info(mach_task_self(), TASK_BASIC_INFO, (task_info_t)&info, &size);
    return (kerr == KERN_SUCCESS) ? info.resident_size : 0; // size in bytes
}

vm_size_t freeMemory(void) {
    mach_port_t host_port = mach_host_self();
    mach_msg_type_number_t host_size = sizeof(vm_statistics_data_t) / sizeof(integer_t);
    vm_size_t pagesize;
    vm_statistics_data_t vm_stat;

    host_page_size(host_port, &pagesize);
    (void) host_statistics(host_port, HOST_VM_INFO, (host_info_t)&vm_stat, &host_size);
    return vm_stat.free_count * pagesize;
}

void logMemUsage(void) {
    // compute memory usage and log if different by >= 100k
    static long prevMemUsage = 0;
    long curMemUsage = usedMemory();
    long memUsageDiff = curMemUsage - prevMemUsage;

//    if (memUsageDiff > 100000 || memUsageDiff < -100000) {
        prevMemUsage = curMemUsage;
        NSLog(@"Memory used %7.1f (%+5.0f), free %7.1f kb", curMemUsage/1000.0f, memUsageDiff/1000.0f, freeMemory()/1000.0f);
//    }
}

My Mac Address is showing "Mac Address: 02:00:00:00:00:00" in my log file.

I have imported the framework and tested with various other configs you have and they work fine.

and code

NSLog(@"Mac Address: %@", [ALNetwork macAddress]);

its not really a problem, but FYI:
while installing via cocoapods, this message pops up:
[!] Unable to read the license file /../Pods/ALSystemUtilities/LICENSE for the spec `ALSystemUtilities (1.0)

This doesn't work with iPhone 64-bit devices

I get this error when linking the framework:
ld: file is universal (2 slices) but does not contain a(n) armv7s slice: /Users/marcus.milne/Library/Developer/Xcode/DerivedData/ALSystemUtilities-bviykdlzbhozoqdhsgktchmuceqh/Build/Intermediates/ArchiveIntermediates/ALSystemUtilities/IntermediateBuildFilesPath/UninstalledProducts/ALSystemUtilities.embeddedframework/ALSystemUtilities.framework/ALSystemUtilities file '/Users/marcus.milne/Library/Developer/Xcode/DerivedData/ALSystemUtilities-bviykdlzbhozoqdhsgktchmuceqh/Build/Intermediates/ArchiveIntermediates/ALSystemUtilities/IntermediateBuildFilesPath/UninstalledProducts/ALSystemUtilities.embeddedframework/ALSystemUtilities.framework/ALSystemUtilities' for architecture armv7s

Hey @andrealufino

ALBattery remaining hours methods don't work for me.
As I saw the infoForDevice method returns nil on device & on simulator it returns the dictionary, but doesn't find the needed data & it returns in both situations "NS".

Tested on iPhone 5 with iOS 8.4, iOS & iOS Simulator with iOS 8.2.

It applies for all the methods listed:

• + (NSString *)remainingHoursForStandby;
• + (NSString *)remainingHoursFor3gConversation;
• + (NSString *)remainingHoursFor2gConversation;
• + (NSString *)remainingHoursForInternet3g;
• + (NSString *)remainingHoursForInternetWiFi;
• + (NSString *)remainingHoursForVideo;
• + (NSString *)remainingHoursForAudio;

Any idea why is that so, any changes in Apple's API maybe?

Thanks for the library,

@kexoth

It would be ideal if ALCarrier could give a NSString with the current radio technology 3G, EDGE, LTE.

Comparing a BOOL against YES is dangerous.
