If you're an Android user, you may have discovered the joy of true multi-tasking. This comes with a price though - CPU cycles. CPU-cycles on a desktop machine aren't a big deal, but when you are powering a dual-core or quad-core CPU with a small battery, this can drain it pretty quickly. Here are a few Apps that really do prolong your Android devices battery life.
With that said, one of the first complaints from new smartphone users is that the battery doesn't seem to live up to expectations. Sure, the 2013 crop of flagship phones seems promising, but not everyone wants a Samsung Galaxy S4 or an HTC One. What's more, not everyone wants to go to Verizon for a Motorola Droid Razr Maxx HD.
