Windows 8 -- Not the problem -- The PHONES are

[Coke Robot]

i just get annoyed that with my Droid, if I take it off my charging dock at home, have it on me all day at work and get home and try to go for a run, it seems like I don't have enough juice to use my Amazon MP3 cloud player and RunKeeper with GPS tracking on the phone without having to charge it for awhile.

A few things you can do to extend the battery life.

1) Turn off the GPS and Bluetooth when you're not using it.
2) Use wireless internet rather than 3/4G when at all possible, it uses much less power.
3) Disable services that are constantly pinging a server on the network (the default SMS app that comes with Android is actually a pretty bad culprit.. if you install a 3rd party SMS it helps. You have to disable the factory one though).

There are a few others as well, but doing these doubled my battery life.

Or, if you have a Windows Phone, you can use its Battery Saver feature that you can turn on yourself or it turns on automatically when the battery is low. It disables push notifications and limits the phone to one app at a time. Even the design of the UI even helps with battery life.

Faster, easier, Windows Phone style!
