Some tips I've found for good battery life.
Last Edit 3/18/2011
Hello everyone. I made this account at first just so I could download all the stuff needed to root my V, but now I wanted to tell everyone what I use to get really good battery life with this phone:
-Rooted with Stock + Xionia Kernel
-Widgetzoid Widget set up to have a Data (3G) On/Off toggle, kept off when not using it. Its set up with the APN toggle and not the APN rename.
- NOT RECOMMENDED ANYMORE, NO BENEFIT -Advanced Task Manager set to AutoKill everything whenever screen turns off
-Set CPU with profile for Screen Off that drops speed down to lowest available (~120mhz)
- 50% Signal Fix installed http://forum.xda-developers.com/showthread.php?t=938677
(if you dont want to install this fix for fear of messing up your cell radio settings you can just turn on airplane mode for ~15 secs every time you turn on your phone, achieves same result)
- Screen Brightness at 50%
-Auto Killer memory Optimizer installed and set on extreme - (I dont think this one is that bad since it only kills stuff if you get really low on memory)
The two greatest helps on battery life I believe are keeping 3G off with the toggle and the 50% fix.
I may be using too many programs ( like 2 auto killers ) but I can have my phone on all day, play around with it for an hour or two, make a couple of calls, and at the end of the day its in the 75-80% range, which I think is great. Overnight if not charged it only loses 1% about every 2 hours.
I know there are other threads on this but its more of people complaining and then you have to dig through pages to find the apps and techniques to actually help your battery life.
If anyone has any other recommendations, you're welcome to post them and I'll update this post so people don't have to dig through it to find them!

If you use this, and you lose your data connection, it will NOT auto-reconnect.
You will have to toggle each time you lose the data signal.
Once installed, the only way to correct it, is a wipe.
You are better off toggling to airplane mode for 10 seconds after boot has finished then turn off airplane mode manually than using this app. It's a nice idea, and a great app, it just doesn't work properly with out phone.
No app that changes data settings work properly with the OV.

I havent had a problem with the 50% fix losing my data connection, and if my data is ever off and i need it, i have the widgetsoid widget on the desktop to turn it on... i was using juice defender and had problems of losing 3g with that though...
also i dont use any task killers anymore after reading up on them... ill modify the first post to reflect that

Is it possible its a bug with the stock rom? Im on the official Zefie not the v port and frankly the only issues I have now is the stupid mms and BT not working as a phone headset.

One of the reasons you might not think it works is that you look at your battery usage through settings->about and see that the Time Without Signal is some really big number (but not 50%). Try this, plug your phone into the charger and reboot it that way. Once the 50trick app has finished doing it's thing, unplug from the charger. Then check settings->about->battery usage->standby time. Magic! I don't think rebooting while charging adds anything to the fix. I think it just hides the few seconds that the phone has the bug before airplane mode is toggled from the statistics of your battery.
Also note that the 50% bug will not drain your battery until you start using 3G. If you have your phone on wifi, the battery drain will be normal.

Um...that fix isnt for the random data disconnects. Its for the 50% without signal bug that drains battery even when the phone is on standby. It has nothing to do with data toggling other than the fact it uses airplane mode to fix an issue unrelated to random data disconnects.

As far as I know every app that messes with this setting messes it up.
What happens, is that once you lose data, it will not reconnect. Next time you go to use data, it will show it working, but you receive nothing.
See what I wrote above.
Before I installed it, no problems. Installed the app, I no longer reconnect after a data loss. Wipe, re-install everything, problem is gone.
I can repeat this over and over with Stock, Stock with Xionia and Rodimus. I am pretty sure I saw it on the 2.3 roms as well. Completely repeatable. The "Network app, *#*#numbers#*#* trick anything accessing the hidden 3g menu causes the same problem.

The reason I have a hard time believing that the 50% fix messes with data and can not be unchanged without wiping is that its only purpose is to mimic the user turning on and off airplane mode and not going into the hidden menu and changing the settings. Therefore that data problem you are encountering should come up as well if someone turns on and off airplane mode then loses data...-LG Optimus V w/ CM7
