Get more life out of your Cingular Blackjack Batteries
This post was published 2 years 11 months 11 days ago which may make its actuality or expire date not be valid anymore. This site is not responsible for any misunderstanding.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.)
