My wife and I purchased two Optimus V phones on 3/6/2011 and both were experiencing the 3G drop and no-reconnect problem. She also charged hers (stock apps only) fully before going to bed and the next day it was completely dead. Mine was left charging overnight, but by 5pm it was down to 30% battery. I called the VM escalation line last night and they were of little help. I did what they said to do (reset my phone #) and 30 minutes later I lost 3G again. I lost 3G about 5 times yesterday and turned the phone on/off to fix it (or airplane, etc). I assume these two problems are now related, so as someone here mentioned, I went to *here* and followed the steps by "pre" (posted below). My phone and my wife's both were showing 50% "Time without a signal" -- which is definitely odd because I can see the cell tower from my office and my living room. After following his steps I have now had my phone on for 18hrs and with moderate use and "Syncs" on (but not WiFi) I'm at 75% battery -- I'm also now showing 0% "Time without a signal" and I have had no 3G drops. The steps were as follows: * Check "Time Without a Signal": Home, Menu, Settings, About Phone, Battery Use, click "Cell Standby" and not the value. It should be close to 0% if you've been in 3G range. 50% indicates a definite problem. To "Fix" - Note the original poster says this change will reset if you reboot the phone and need to be redone: * 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)". As mentioned in the link, now charge your phone to reset the battery usage statistics and after an hour or so monitor the "Time without a signal" value. The problem seems to be from an incorrect network type value that is originally set/saved despite it showing the correct value. This has fixed both of our phones so far today. If anyone else is having this problem and is able to test this fix, please let me know if it works so that I might try to contact VM for a permanent fix. Until then, you might wish to get the "Any Cut" app which can create a shortcut to the phone's "Testing" menu to avoid dialing the above number. Once you have the app: * Click and hold on desktop * Select "Any Cut" * Select "Activity" and "Testing" Some people also note that they get better battery usage with WiFi left on vs 3G. I'm not sure if this is due to this issue or not, but I'll do further tests leaving WiFi on tonight after a full recharge. The default WiFi "Sleep Policy" on the Optimus V is set to turn WiFi off "When screen turns off". If WiFi is truely better, then one would need to set this to "Never". (Note on some other phones WiFi defaults to "Never" sleep.) To change the setting: * Home, Menu, Settings, Wireless & Network, Wi-Fi Settings * Click the Menu button and select "Advanced" * Select "Wi-Fi sleep policy" and change to the desired value Finally, if anyone has talked to a VM tech support person and found a permanent way to fix any of this, please post the solution that you found.
