    Default Possible app?

    Legion- I tried the Fix50 app & it did fix the reporting problem for me but didn't seem to do much if anything for the battery drain and I still got the annoying periodic data drops several times a day. Has anyone looked into making Greenmonster's directions for properly setting the radio into an app like fix50 that would kick off at reboot? I'm on day 3 (no reboot) and seem to have just about tripled my battery life and have had no data drops (or the phone has properly reconnected like it is supposed to).

    There is some talk of this on an XDA forum (Developing CDMA Preferred Network permanent fix - xda-developers) but the last post was in October of 2010 and since I have fewer than 10 posts over there I can't post on dev-related forums.

    Default Just to clarify...

    Oh- this is the fix I'm referring to...

    To check if this bug is affecting your phone, 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.

    To fix the issue, dial *#*#4636#*#* and it will load the testing screen. You do not have to press call. Select phone information.

    My understanding of the bug is that even though the preferred network is set to "CDMA auto (PRL)", it is actually set to "GSM/CDMA auto (PRL)" because of a display bug.

    The fix is to press Menu and then "Select radio band". The process will then force close. Go back to Phone info and select "CDMA only" and then select "CDMA auto (PRL)".

    Interesting theory, but this has not been my experience. My experience echoes that of mmarz: if the phone isn't on wifi and I've forgotten to do the TWS fix the battery usage increases 400% and the phone gets noticeably warm.

    Note that in the screen shots the phone is on wifi.

    Default Update- data drops/TWS

    So I finally had a hiccup about 9:00 last night that caused a data drop- it was right after I lost a phone call & during a pretty serious storm, so don't know if that affected anything. I'm still pretty happy- I've never gone more than three or four hours without having to do the airplane mode toggle due to data drops- 60 hours without a drop is encouraging!

    Time without signal also stayed in the single digits...

    Okay, *total* newb here--lurked and read most of the week. Just got the phone on Monday. (And I cannot stop playing with it.)

    I did the phone setting thing described here, and am doing the airplane mode toggle every time I take the phone off charger. This does seem to help--one night it almost completely drained the battery just sitting on the dresser. Last night it used a small percentage, so that was a vast improvement.

    I am confused though--I am reading in some posts (although some may have been in links I followed) that 50% time without signal is bad, and in others that it is good.

    Which is it?

    (Previously mine read 50%. Right now it reads 1%, but it hasn't been on 3g very long today.)

    Thanks!

    Mine is shown as 48%
    Time without Signal 0%

    is that good?

    Default

    My cell standby is at 24% with 1% without signal. That's after 78 hours since charged (battery at 26%). I've never noticed a problem, or had any high drain (unless I really get to playing games or tweaking apps). I do put mine in airplane mode 12 hours each night (no cell signal at home).

    Thanks for inputs. Turning of GPS, 3G and WiFi keeps battery from draining. Good to know about GB. Need to become familiar with droid and get helpful apps.

    it is the cell standby with out a signal, change to cdma a only then back to auto should give u more like 2% time without out signal and battery life will double but for some reason it stops working as well after so many reboots and performing the change.

    hey i am new here could someone help me out.

    this is my first android phone and i have notice what everybody notice with the battery drainage for the OV phone.

    my current battery use is:

    cell standby: 47%
    time w/o signal: 0%
    phone idle: 45%
    Android sys: 6%
    display: 4%

    is this a normal battery usage? if it isn't how can i reduce the %.

    also when i dont use the phone, i lose 1% prob every 10mins (i have quick settings/advanced task killer/ and battery booster installed, along with other apps). and when i use 3g and going online, it burns the battery pretty fast.

    Default Re: Excessive Battery Drain (Even On Standby)

    User KSmithInNY explained earlier that it could be a display problem. I must agree with him because my phone says 50% BUT the time my cell radio has been going is twice that of the time my phone has been on. I think he has it right that we don't get that othee signal so it automatically has a 50% even if you have a signal... so I don't think it is a problem for signal or battery just a problem with the settings display.

    Refer back to page 8 the first post at the top.

    Here is my observation.
    I tried all the battery booster / widgets. None of them in my personal view do squat. In some cases they drain the battery even faster. Surfing on the web uses more signal which in turn uses more battery life.
    Anytime you hit the net, the battery is gonna get sucked down, it just the nature of the beast. I opted to just leave the phone bone stock and is works just fine.

    Default Re: Excessive Battery Drain (Even On Standby) internal short?

    I found a problem I had that was causing unpredictable battery drain on my OV. I keep the phone in a special pocket in a fanny pack.I would sometime noticed that if I pulled the phone out the camera would be on, even if I carefully avoided pressing the camera button. I disabled that button by editing the button mapping file. That stopped the camera but not all the problem. Sometimes if I moved the phone or squeezed it a bit the phone would wake up. Breaking down the phone noted that the little carrier board for those buttons seemed to be overly sloppy. I added a strip of plastic between the board and the internals of the phone. I also may have over reacted by placing another strip of plastic in front of the switches. (removed but saved the little rubberized buttons to fully ensure the buttons don't get pressed). So far so good.

    I have the LG Optimus V since last friday and at first I had battery issues, got 6 hours then dead. HERE IS HOW I FIXED THE BATTERY ISSUE........after I did the items below I went from using 7 - 10% per hour down to 2% per hour of battery use on the average....
    First I downloaded the android advanced task killer set to aggressive/crazy...
    Second I unclicked data enabled in wireless/networks--mobile networks.....
    Third lowered the brightness to less than half & screen timeout 30 seconds...
    Fourth I plugged in the charger and removed the battery then put it back in and let it recharge--this reboots the battery and the system....let it charge overnight phone off...
    IN this setting with data enabled unchecked I CAN recieve/make calls & recieve/send text messages....
    When I want to check email or go on the internet I CHECK data enabled....
    VERY VERY HAPPY NOW !!!!!!

    If you flash a custom rom, you will be able to get at least 12 hours as opposed to six while using web and data.
    its a better solution then turning off data access amd dumbing your smartphone.

    I had to fix my settings for more battery life. I adjusted the brightness and I always shut down running applications. Also when charging I put the phone in airplane mode for a quicker charge.

    My Optimus V says that 50% of my battery drainage is cell standby! I use 1 click clear and Juice Defender to close all my running apps, clear messages, texts and phone calls. I never use the radio and NEVER have it running so I don't know what gives? I guess it could be a display bug, but is
    is draining my battery..

    Do you use the lock screen on your phone? I have mine set to 30 seconds so it locks it so the buttons do not get pushed accidentally.

    *sigh* :shakeshead:

    You are always using cell standby... that's what gives you service. Unless you are in airplane mode

    Brand new here at Android Central and also brand new to Android smart phones. If this works, I may even subscribe to the daily newsletter published here. Am at the library and running out of time plus need to recharge to zero the battery use settings. Will update tomorrow with results.
    Currently praying to the Android gods for success. Regardless of the results this thread was hugely beneficial and succinct and professional. If the rest of the forums and threads are similar I may have found a central location for my newbie-smart phone questions. Thanks to all who replied here.

    There is, in fact a bug with the LG OPTIMUS phones. From the LG Phones blog, which clearly states the problem and provides solutions (mentioned on this thread also):
    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. Ive 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 Evos 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 phones "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.
