I'm getting a second hand Streak 5". I don't have AT&T, but I recall hearing that dell had also made a Wifi only model. My question is: can I load a Wifi only rom (are there even any?) on it and disable the phone/3G?
There are no wifi only streak 5's only streak 7's have a wifi inly model
try dialing *#4636#*#* (*#*#INFO#*#*) then press call.
try phone information, I beleive there is a button to turn radio off, which should completly disable 3G radio.
Not sure if this will stick after reboot, but I think it should.
settings also gives you the option to turn off data, etc. and if there's no SIM card in it, I dont imagine it will use any radio.
I use APNDroid which seems to disable radio pertty successfully, only allowing wifi connections.
I use my Streak 5 in wifi only mode.
I started off just not having a SIM in it, but I found that cell standby was still eating loads of battery - as much as the phone idle was, due to the fact that they are still able to make emergency calls even without a sim.
The really simple solution is that I installed Widgetsoid and added a widget with toggles for Airplane mode and for Wifi on it. I assume any widget app that allows these toggles would work. I then turn Airplane mode on, which kills the cellular radio, both 2g and 3g, and turn on wifi when I need it - which overrides the airplane disable.
I've even found that JuiceDefender can auto-toggle wifi while in airplane mode based on running apps, though only after rebooting while in airplane mode - before the reboot, it quite sensibly saw airplane mode and left the radios all off.
Thanks for the tips.
Got it up and running nice, again thanks for the tips.
And just to clarify, even if I throw a custom rom (probably StreakDroid) I can't pull phone/3g functionality? Could I pull some apks from the StreakDroid zip to get make it wifi only, or would I need a custom kernel?
Being fed up with the random wakelocks that Dialer produced on my Gingerbread P500, I spent a while searching for the cause. It turned out to be DataTracker-FD (found out using the amazing BetterBatteryStats app - http://www.cri.ch/sven/doku.php/computing/android/betterbatterystats ), which deals with Fast Dormancy (http://www.computerworld.com/s/article/9191759/Fast_dormancy_to_improve_smartphone_networking_and_battery_performance_ ).
Now, in theory, Fast Dormancy should be a great feature! But, if your network does not support it, DataTracker-FD will still drain a lot of battery through the wakelock. The SGSII secret code for deactivating it doesn't work on the P500, and neither does the nwk_info.db method. Luckily, you can deactivate (or change its timeout) through the LG hidden menu...
1. Dial 3845#*500#.
2. Go to Modem Setting > PDP Setting > [0] Set Fast Dormancy
3. Select your desired timeout (or "Disabled"). You should now be done! (will look at Battery Usage in a little bit, to see if a reboot/Dialer FC is also needed)
Optional step 4. If you still see no difference, set your desired timeout (or "Disabled") a few more times.
Hope it helps.
/* Edit: It doesn't seem to help, we might be back to square one. Does anyone have any idea on how to completely disable Fast Dormancy? We might need a dev to look at the source code of Dialer and make some modifications... Right now, if your phone stays awake after using Data, the only current workaround is FCing Dialer from Applications. */
EDIT 2: A SECOND TEST, USING THE ABOVE METHOD TO DISABLE FAST DORMANCY, YIELDS POSITIVE RESULTS! THE WAKELOCK IS NOT THERE ANYMORE, EVEN AFTER SEVERAL RECONNECTIONS TO HSDPA!
It needs way more testing though, I will reconnect to data and leave the phone idle (screen off), then see what happens, and I will reboot the phone to see if the setting persists.
EDIT 3: Yes, the setting persists, and the wakelock is still not running! The final test will be done after it has completely charged, because there still is a small possibility that the wakelock is so far not active just because the phone was charging.
Edit 4: Straight after unplugging the phone, DataTracker-FD started running, without being connected to HSDPA (I was in a phonecall). In 17 minutes (of mostly talking on the phone) it drained 1% of the battery - so, it should last for about 29 hours with the same usage. Now I have started HSDPA and left the phone idle for 10 minutes, to see how much it drains and how much it drains after I turn data off. It just might be that, while the phone is still awake, it doesn't drain a large amount of battery. If it actually still drains a lot, this tweak definitely only /seems/ to work while charging (maybe BetterBatteryStats was reporting false data or FD just doesnt' work when charging).
Edit 5: Here's a pleasant surprise. Right after connecting to HSDPA and putting the phone to sleep, the Awake bar in Battery Usage faded out. In 5 minutes of idling with data activated, the phone drained another 1% battery - not sure how well that is, since it amounts to 8 hours of data on a full charge, but it's better than 12 hours of idling with no data on a full charge. Currently repeating the test. Just got an email on Yahoo pushed, I'll get to see the influence on awake time of that as well.
Edit 6: After 10 minutes of idling with data ON, a bit over 1% of the battery is gone. This is a fantastic value, and the Awake bar is only dotted in this period of time. DataTracker-FD seems to be running a bit in the background during the data connection, but stopped once I turned it off. It might just be me, though, because aLogCat still can't find any entries for Fast Dormancy. Now leaving the phone idle with no data for a while to look at the evolution of Awake time.
Edit 7: After about 45 minutes of complete idling, the battery went down 2%. This would mean the battery would last for about a day and a half, which is meh, considering I OC'd the phone to 730 and don't really use a task manager.
The conclusion: YES, disabling Fast Dormancy does work using the above method, and it does help battery life!
Edit 8: After another unrelated reboot, DataTracker-FD is once again awake after using data, but this time it draws significantly less battery. The Battery Usage graph shows no difference between sleep times and awake-because-of-FD times.
Edit 9: During the night, the phone drained 30% battery, once again because of some random action of DataTracker-FD. This is still not a definite fix.
"Connection problem or invalid MMI code" when I dial that number..
I remember that long ago I dialed the number and everything was fine.
Well you shouldn't literally call it, just type it in Dialer and it should open the hidden menu.

When I just type it in dialer, nothing happens.
I see. It might not work on CM.
Updated the OP a couple of times, you might want to read it.
Considering I am still on Froyo v2.2.2, could this be of interest for me too? There's no abnormal battery drain on my phone, but if I can improve the battery life by tweaking this setting, I'd gladly do it.

I didn't have such problems on Froyo either. It MIGHT help, but as you can see from the numerous edits to the OP, it's not a clear win yet.
So it need to be disabled twice to stop working?
I've been looking for this service since using that Battery App but theres not much information of that in the web.
I'm not sure just how many times, but it took about 3-4 times for me until I was completely sure the wakelock stopped running and the phone went into deep sleep each time I locked it.
Yeah I think I got it doing it twice, FC phone and rebooting, btw maybe you can check system/etc/flex/flex.db and flex.xml there are fast dormancy settings there
@metalboy94 I mailed LG regarding Fast Dormancy and the reply i got was that P500 does not support fast dormancy. My phone does not switch from H to 3G. I tried enabling it many times using secret menu but it does not work.
I asked him if GB ROM/Baseband supports fast dormancy, he replied saying GB hasn't been released for India

There are? Thanks a bunch, gonna try those methods as well!
@atulalvenkar: Well, it still draws power from the battery, so at least they could have done something to the Dialer if it's not supported at all.
Edited the OP once again.
Are you guys checking on GB or Froyo ROM ? I can't see flex.db or flex.xml in froyo ? Stock or CM7

Stock GB. I found it, but you have to fill in the info for your operator if it's not on that list. Guess which is my situation.

Yeah my operator isn´t there also (I´m on a custom V20g ROM and I´m not from Romania) but i got the flex files from the Froyo stock so im going to try using that information to replace one of the V20g operators.
Also tried putting the Froyo ones on GB but get a lot of FC
Updated the OP again...
I tried to change the FD settings in the hidden menu, but the setting does not "stick", so I don't know if it's actually OFF or not.
However, I found that DataTracker-FD only keeps the phone awake when Wifi is on. If I'm always on 3G, FD seems to work and keep the phone asleep. Overnight with wifi off and 3G on, it only drained 2% battery.
I'm on official GB2.3.3 with PaoloM's kernel v5.
Strange.
hey maybe let´s try this:
Code:
ro.ril.disable.fd.plmn.prefix=23402,23410,23411,
have to put that on the build.prop then restart, the values must be changed to your carriers code, you can get that code from adb typing
Code:
adb shell
getprop gsm.operator.numeric
Then the system should show the number

But did you see how many MBs the phone used? Cause if it's too much, people will definitely prefer just turning the phone off.
@Roqu3: I think I tried that before and it didn't seem to make a difference.
Worth a shot tho.
I'll try both of your methods if I still have the issue when I get my phone back from the service center.
Sent from a crappy rebranded Huawei using my hands
I've been using the app BetterBatteryStats as recommended by XDA to determine why my RAZR is awake much of the time, even when the screen is off and data is turned off. It turns out the problem is the internal process IMS_Data_Retry. This process apparently keeps attempting to establish a data connection over cellular data, at least 4G LTE. It aquires a wake lock while doing its work. This one process can keep the phone awake 95% of the time. The only way I have found to semi-stop it is to turn on 4G LTE. Even then, while it stops consuming CPU time (supposedly), the count of retry attempts keeps going up. (Putting the phone in Airplane mode also stops it, but then calls are stopped as well.)
There is a setting in /system/build.prop that I thought controlled this process:
ro.cdma.data_retry_config=default_randomization=2000,max_retries=infinite, 0, 0, 120000, 180000, 540000, 960000
I looked at some code references I found ( http://hi-android.info/src/com/android/internal/telephony/cdma/CdmaDataConnectionTracker.java.html ) and learned that the above values are in milliseconds. It seems that the default_randomization value is added to the other values in the list to create a schedule of retry attempts, but I wasn't able to figure out all the parameters to the method, if I even have the right one. I tried changing "infinite" to a small number under 10, but it had no effect - the process just keeps retrying forever.
Is there a dev out there who knows more about this? I want to limit this process because I seldom use cellular data right now and am usually on WiFi. It hinders any attempt to extend battery life. Is it a bug? Is it fixed in a later release (I'm on .748 stock) ? Do any of the custom ROMs have this problem? Can the build.prop setting I found be given values that limit the amount of time this process holds wake locks?
Thanks.
Did you ever get any resolution on this? For me, I think the problem started with the ICS update this summer. I constantly have gsm_data_tracker, RILJ, and IMS_Data_Retry using up the battery (in that order from highest to lowest). I tried wiping cache which helped the 1st time it cropped up and then it came back. I also tried a tip I saw somewhere for turning on airplane mode, rebooting, and turning off airplane mode (though mine as soon as it reboots, it already turns off airplane mode which it shouldn't). That worked for several weeks, but I had to do it EVERY DAY when I got to work. I think it's something with the 3g repeaters in the building. I did have it so it was wifi only (mobile radio off) on my work profile in profile scheduler, but then I needed cell for some mms stuff, so I ended up enabling it again. Basically when I come in the building and forget about my phone for an hour or 2, I go to get it out of my backpack and it will be hot from processing and 20% or more of the battery gone when I've done nothing in 2 hours of being at work. I saw somewhere that someone though either gsm_data_tracker or RILJ was related to something with the alarm, which I do use my phone as my alarm, but I use a 3rd party app. With the time change, there were a few days I woke up before it ever went off, so I turned it off before it did alarm. There were no differences with the partial wakelocks or battery drain in those cases. Unfortunately, I don't have another alarm readily available to get up for work right now and on the weekends when I don't need an alarm, I can't replicate the cell repeater at work issues, since I wouldn't be around the cell repeaters. As fart as in the building at work, until I reboot with airplane mode and all of that, the cell signal will bounce between like 0 bars/3g and lots of bars (no indication of network) and some bars with 1x network. It's all over the place. The airplane mode/reboot used to stabilize that, but it doesn't seem to be doing the trick anymore the last few days that I've tried that. I have to leave my phone on the charger as much as possible at work so that I don't leave for the day with a dead phone.
I root my SGS2, currently using SlimRom.
Problem 1:
Everytime my battery reaches around 50% and when I restart my phone, the battery drops to around 20%. I tried using the BatteryCalibration app but it doesn't seemed to calibrate correctly.
Problem 2:
Sometimes my phone just disconnect from my local phone service network.
I have tried switching off the SIM card lock and toggling the airplane mode but it just doesn't search for any network. In the Settings menu, I do a manual network search but an error was display.
Is it because of the ROM or kernel?

1 word for you expirement
change the kernel and see how it does if the same results try another Rom with a different kernel it's the only way to know for sure
Which kernels would you recommend?
I am using SGS2 I9100
Hi
My friend gave a phone as gift to me but i think he may used it to hear my calls . is that possible ?
because there is no sim card on it and there is a coverage sign on top and battery finishes so fast and when i disable data connection it will automatically become enable?
i had attached image of my phone
That's normal. Even without a SIMcard the phone still provides access to the emergency network. (112, 911, 999, etc.) Such is a mandatory requirement as per international law.
Put it in airplane mode, that'll disable the mobile antenna. You can then manually turn on every other connection should you require it.
As for a fast battery drain, completely different case. Check for a wakelock.
naah...don't be paranoic man
