Re: Battery Life Retrieval- In a few words, that depends on whether you are talking about one specific device or a variety. For Instance, On a system that I use: Start Menu>WindowsSystem>Control Panel>All Control Panel Items>Power Options would drill down to where I would choose Dell Extended Battery Life Options and get a display window popup with a Battery Status Tab including a Bargraph. This is great, but you would have to set-up a remote-control type client which some folks might object to. For instance, the Battery Status Tab is accompanied by a Battery Health Tab within the Battery Meter Popup. From the Battery Health Tab, it might be possible to order a new battery online from Dell ( Using their name from your application ). Now while that may seem unlikely, giving you that authority might be easier for them than it would be for you to set up that level of access to their Windows PC. This might be a bit easier on an Android mobile device, provided that all of the ones you wanted to access had the same firmware levels ( essentially all the same hardware ). It might work until someone upgrades the Android OS or just a specific part of the firmware. Thus I would discourage it unless you have a great amount of time and money to engage in the project.
