I bought a LG Optimus V a week ago at my local Virgin Mobile. I charged it overnight last night and normal operation, phone, texting, browsing the features on the phone, but can barely get 8 hours out of my LG Optimus V. I’ve tried the trick many times where I let it drain completely, charge completely, repeat, and this still happens daily. This is an extremely frustrating problem seeing as I would like to be able to use my phone for more than one day at a time. LG Android Phones
Finally, I have found the cause of the problem. It appears that the LG Optimus V suffers from the same GSM/CDMA auto prl cell standby bug that affects the Evo’s battery life.
To check if this bug is affecting your LG Optimus V, go to AboutPhone -> BatteryUse -> CellStandby and check to if there is an entry for "Time without a signal". If your phone has a solid signal to Virgin Mobile at all times, it will read 50 percent. LG Phone Problem and Solution
To "Fix" – Note the original poster says this change will reset if you reboot the phone and need to be redone: LG-Optimus info
- Dial *#*#4636#*#* which will go to the phone’s "Testing" menu.
- Click "Phone Information", then Menu, then click "Select radio band".
- Click "Force Close" and return back to "Phone Information"
- Scroll down to "Set preferred network type:"
- Click the "Set preferred network type:" button and select "CDMA only".
- Click the "Set preferred network type:" button again and reselect "CDMA auto (PRL)".
To verify that this fixes the issue, charge your phone to reset the battery statistics. Unplug the charger and check back in an hour or so. It should no longer say time without a signal (assuming you are in an area with a strong signal strength). This should cut the cell standby battery usage in half.
The fix is not permanent. If you reboot the LG Optimus V, you will have to make the changes in the testing screen again.
