Thanks to a recent cell phone contract renewal, my current phone is a Samsung Katalyst (I also now have a Plantronics Explorer 222 Bluetooth headset from Woot.). This phone is neat, but I was really disappointed with the battery life. In a nutshell, I was having to charge my phone daily. Since my old phone easily lasted a week or more, this was really frustrating. Even my Motorola Q lasts longer than a day!
I finally found the source of my frustration and I’m back to enjoying long battery life. The Katalyst has the ability to make VoIP-based calls using a Wi-Fi network. Although this is a really cool feature, with no usable network the Wi-Fi feature drains the battery life at an alarming rate. So I disabled Wi-Fi: Menu ⇒ Settings ⇒ Wi-Fi ⇒ Turn Wi-Fi Off. Voilà!
