So i recently flashed the latest 2.3.6 to my phone and have juice defender and around 33 percent screen brightness. It seems my phone drains 1 percent on standby which is fine but when the screen is on it drains 10 percent in 20 minutes. I have auto sync off and low auto brightness. So my question is should i just flash a custom kernel, or revert to a older firmware. Thanks any ideas appreciated.
