You can only monitor the charge level and charging state (full, plugged in, discharging) on the device.

You cannot (to my knowledge) get any additional info, though if I am wrong there I would love to know more!

On Android you can also get the battery tech (Li-po, NiCad) but Apple only users Li-po.

Sometimes you can get t he battery serial though I'm not sure how reliable this is and what platforms.

YMMY:Sometimes these answers change depending on hardware and OS version.

I think you figured out ideviceinfo...

Hi,

Thanks for the info, how do you use the ideviceinfo? Can I monitor the battery with my iOS application with it? or is it run from desktop for an attached device?

I guess I would have to trigger the domain with the command:

ideviceinfo -d com.apple.mobile.battery

I need to monitor the host platform battery and charging progress within my application if possible.

I guess I will try to fetch all the information per platform, thanks for the info.

No. I had to write my own JNI api. Curiously, for iOS, the ideviceinfo binary can give you more than the device itself.

Hi,

Is there any Qt API (I did found some into the old QtMobile) that can be used to probe the main battery on the system (I want to target iOS, Android, OS X, Window and Linux). I was wondering if any Qt API exist to monitor the charge level, the current, voltage, capacity, health, etc. I think I won’t get everything on all platform (yes I’m looking at you iOS lol). If anybody have a lead on this it would be welcome.

Thanks,

Jerome
