Get more life out of your Cingular Blackjack Batteries
Posted by Chris Leckness on 11/27/06 in Cingular, Smart Phones
It’s no secret that even though the Blackjack is an unbelievable Smartphone, battery life is a bit less than desirable with HSDPA use.
The solution is an phone code to open a secret Admin Settings screen that will allow you to switch between GSM Data (Edge/GPRS) and WCDMA(HSDPA).
1. Enter *#1546792*#
2. Select Option 3 Netowrk & Call Settings
3. Select option 5 Network Mode
4. Select GSM
(Choose WCDMA to change it back when you need it.)
