Please post your settings if your multiplier is higher than mine, I would love to improve my battery life even more.
I am running JD 1.6.9 beta
Here are my settings:
Timeout - 30s, lock after 2m
CPU - Do nothing
Schedule - Enable Data/Wifi for 2m every 30m
Night - Keep Data/3G/Wifi disabled 0300>1100
Battery - Keep Data/3G/Wifi disabled while below 30%
Traffic - Leave Data/3G/Wifi enabled while >10KB/15s
Peak - Do nothing
Charger - Leave Data/3G/Wifi enabled while charging
Screen - Leave Data/3G/Wifi enabled while screen unlocked
Location - Do nothing
Under 3G: Only disable on Lock pattern timeout is selected
Under Wifi: Auto Disable, Enable on Schedule and Screen selected
Under Schedule: Quick is selected
Under Battery: Charger selected
Under Screen: Only after unlock selected
With these settings I got 20hrs on one charge. I received a x2.85.
It was charged to 100% around 0130. From 0130 - 0400 light market searching and a couple of games. From 0400 - 1100 I was asleep. From 1100 - 1430 light use a couple of texts, a couple of short calls. From 1430 - 2130 heavy texting, a couple of calls, and constant searching for 3G because I work in an area with horrible reception and also going in and out of buildings where I have no signal.
Then I disabled JD and did my same routine.
With JD disabled I got 18hrs on one charge.
Using JD increased my battery life by 11%. I would say that makes it worth the money.
