So far, not a single person has been able to actually find a wifi bug.

Every time someone thinks they've found it, things have been working as intended.

If you have an app that causes lots of network traffic, it'll inhibit deep sleep, but since most of the time spent handling the network traffic is in excessive suspending/resuming, Android OS gets the blame and not the responsible app.

Useful references:

http://xdaforums.com/showthread.php?t=1308030 - My list of known identified battery drainers

Let me guess - you are running Skype or another IM application that does not use Google C2DM? (As far as I know, only Google Talk and Tango use C2DM)

I'm surprised that turning off wifi didn't make things worse, unless in your case the app responsible behaves differently when on a cellular network, or you have packet data disabled.

BetterBatteryStats is almost useless for hunting Android OS drain, as it does not show kernel wakelocks. The only way to get the truth is to get the contents of /proc/wakelocks
[AT&T Samsung Galaxy S II SGH-I777] praramis:
thank you entropy for that info but yes im stuck at the fact that even on mobile network it dont drain like it does with wifi which im not a pro or anything but im just assuming that it cant be an app cuz if it was i would think it would use the same amount of data whether it was wifi or mobile cuz internet is internet but for me i dont know about other ppl everytime i turn off wifi my battery dramatically increases by alot and my android os is never the highest anymore when its off so i dont know if this will do anything but i will do a factory reset and try my testing again like that and see what happens.... plz correct me if i say anything wrong im just trying to help but i only know so much im not a dev lol

p.s. *edit* oh and to answer your question no i am not using any type of im like skype or what not the only thing i have on the phone is the talk thats on it but ive never even clicked it before so it has never been run yet or set up or w/e not sure of that matters but yea... but thank you entropy for that info it really helped me think a little bit more
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
I agree on Bluetooth. I disagree on wifi - Even for background data, wifi is FAR more efficient than cellular data in terms of power usage. There is no longer any reason to turn off wifi, unless you have a misbehaving app that consumes lare amounts of data when on wifi.

Unlike previous devices, the standby drain of the BCM4330 chipset in our phones is EXTREMELY low.

If Samsung's power_profile.xml numbers are correct, the wifi standby drain current of the BCM4330 on the Galaxy S2 is less than 1/10 that of the chipset used in the I9000/Captivate.

However, radio data is far less power efficient than it was on the I9000/Captivate - A change in the architecture of our phone's radio interface means that any radio data transfers, even for a single packet, incur a minimum 6 second wakelock penalty. (Compare to an average of 1 second for small wifi packets.) This doesn't even count the power penalties involved in transmitting to the tower vs. transmitting to a wifi access point.

In fact, when taking these two things together (high wakelock penalties for radio data, and wifi standby drain 1/10 that of previous devices), you should actually not only avoid turning off wifi, you should set the sleep policy to "never" so that it prefers wifi to the cell radio.

You are incorrect. Some apps specifically check whether they are on wifi or on cellular data and change their behavior accordingly. "Internet is Internet" is not true - cell data is fundamentally slower and more expensive in nearly all situations, and as a result, many apps behave differently on wifi.

For example, normally Google Talk will not allow video chat on cellular data, only on wifi, unless it has been hacked to change that behavior.

Some apps specifically have "use this feature only when on wifi" checkboxes, such as Amazon MP3.

I am 90% certain you have such an app somewhere driving data transfers.

Turn on wifi, reproduce the drain, and pull /proc/wakelocks as documented in the threads I linked above.

There has, to this day, not been a single documented case of the wifi chipset just randomly "wigging out" and keeping the device out of deep sleep - in EVERY single case, root cause was eventually traced back to network traffic, which could then be traced to an app. (For example, Skype in AndreLux's case.)

You might also want to install something like My Data Manager to see what is generating your network traffic.

When I first got my GS2, I was getting rapid battery drain and high heat. Turns out, I had put a SD card in that used to be in my old phone, and Google+ was uploading all the old pictures and videos that were on the card. My Data Manager showed me that this had used almost 800M of mobile data.

My data manager will show you what your usage is on mobile and on wifi, and which specific apps are using how much.
[AT&T Samsung Galaxy S II SGH-I777] AvengerBB:
Trillian does as well.
[AT&T Samsung Galaxy S II SGH-I777] praramis:
you guys are such a great help thank you but where can i find your data manager?
[AT&T Samsung Galaxy S II SGH-I777] praramis:
thank you im learning every day because of ppl like you who like to share information like that i would love to reproduce the drain and pull the wakelocks but honestly i have no idea how to and i havent really searched for it either but i think i might just have to learn how to use adb and what not hopefully i can find out what app is draining my battery and causing android os to be super super high thx
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
I gave the ADB commands necessary for pulling the wakelocks file in one of the threads I linked on the first page.

For getting ADB set up, if you're on Windows you may want to look for Droid Explorer (Google it) - it's a pretty nifty frontend to ADB and I believe it helps you install ADB.
[AT&T Samsung Galaxy S II SGH-I777] jetarpon:
The name of it is "My Data Manager." It's in the market.

It's not mine, I just use it.
[AT&T Samsung Galaxy S II SGH-I777] punjabiest:
Okay..u guys should try out a app called "WIFI STATUS". It gives u a notification when your wifi is on but not connected. Really a awesome app.
[AT&T Samsung Galaxy S II SGH-I777] praramis:
thank you i will def look into that im actually installing right now.....

thx i will try this out
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
On but not connected shouldn't be a problem for our devices - see my previous posts about the fact that our standby drain is supposedly VERY low.

On but transferring lots of background data when connected will go killtacular on your battery.
[Desire Q&A, Help & Troubleshooting] supriza47:
So my first and most important problem right now it that my camera doesn't work the camera opens with a black screen and to close it you have to press home.

i just flashed Cool3D AceS v3 CM7/r2 Hboot Version

and if my radio is 32.49.00.32U_5.11.05.27 would that be the problem

also i was wondering what the difference between the two versions by Cool3D AceS were. Apparently they weren't obvious to me so i would like to know please

I also had a bootloop problem on my previous rom(MIUI)which was the the reason i had to switch. It wasn't exactly a bootloop because it booted up completely but after 10 seconds it will restart. i've tried factory reset, formating sd, and other miui including uk roms and us vs. but it still happens. Have anyone else experience this?The only thing that solved it was the rom i have now.

can someone help me please thanks in advance

I`ve got the same problem several days ago. Tried to flash same ROM (Runnymede 3.04) without full wipe. Nothing changed. Moreover, when I press Home and kill camera application with ATK, the power consumption raises up to 200-300 mA and battery drains very fast. Did anyone managed this problem? It seems to be hardware problem, Isn't it?

I installed Cyanogenmod 7.1.0.1 on my Xperia Ray (ST18i). Now I want to get back to firmware with the FTF package shared in this thread.

I'm trying to flash the package using Flashtool, but software doesn't recognize my device. I select "SK17" from the list (as it was adviced somewhere in the forum), but when I plug the device with flash mode Flashtool says:

Error flashing. Aborted.

Now unplug the device and power it on

Then go to application settings

turn on Unknown Sources and Debugging

Unknown Sources and USB Debugging are turned on, I installed all USB drivers (ADB, SEMC USB, Gordon's Gate) on my PC, I also installed PC Companion and SEUS. But I still get the same error.

I'm only have this issue with one person, my girlfriend...so its the person I txt the most and quite aggravating.

When I send her a msg, it makes a different thread then when she replies so each one has their own thread. It only makes 2 threads so one is from me (sent) and one thread is from her. All my other sms work fine.

I did notice if i use quick reply via chompsms, it stays in one thread but if i use the full window reply, even when i msg in the right window, it puts my msg in the other "sent" thread.

How can I fix?

I've tried deleting all threads, deleting contact, renaming contact, and so forth.

I just got done SBF'ing my phone (DX2) from the Atrix ROM because I didn't know about A-Key's and thought I lost something major. Anyway, I still plan on running a custom ROM but does anyone know if Verizon could detect that by chance when I call to get my phone re-authenticated? I don't want to call them twice in a matter of an hour or so.
[Android Q&A, Help & Troubleshooting] Skelente:
AFAIK VZW cannot tell the difference. Furthermore, I don't think they care how many times you *228, as I've done it multiple times over the past week or so, and I know my friends done it a couple of times in an hour when he was first starting out with his DX. VZWs primary concern is that your MEID matches what they have on record, and isn't reported as stolen. They only really care if you have a custom rom on your phone if you take it in for repairs.
[Android Q&A, Help & Troubleshooting] Murdoc419:
Ok, thanks. Just to clarify I'm not doing the *228 activation. It's activated and I can text, browse, etc. but I cannot place calls because my A-Key was wiped somewhere along the line. I have to dial #8899 and actually speak with someone. That's where I'm concerned about whether or not they will be able to detect the ROM and in turn void my warranty.
[Android Q&A, Help & Troubleshooting] Skelente:
I don't believe they'll be able to detect the ROM, but have you tried *228? I just don't understand why you would have texting/data but not voice.
[Android Q&A, Help & Troubleshooting] Murdoc419:
Yes I have done *228 twice. The problem is that the A-key (authentication key) was lost during one of the hard resets. I'm not sure why it happens but it does. I'm also not sure how you retain texting/data but lose voice. Here the thread I found that has a little more detail and the solution to the authentication problem:

[Android Q&A, Help & Troubleshooting] Skelente:
Reading through that thread it doesn't seem like getting the A-Key would create any complications. Those people were in the same situation as you, and if they wanna know why you had a problem, then you had to hard reset, after installing some wonky programs cuz you're a dev.

Ok, soooooo I'm switching over from the Droid Incredible 2 to the Droid 3 due to absolutely horrid reception issues. I never get higher than -100dbm anywheres, and this is the 4th one I'm on. So, Verizon is sending me a "certified like new" Droid 3. My first question is what is everyone's experience with reception. Does everyone have a rather good experience with the reception or is it kind of iffy? Secondly, what's the modding scene like? Is there like a "popular" mod out for the D3 sort of like what Cyanogenmod is for the Incredible 2?

I had an Inc1, had my eye on the Inc2 but it just wasn't good enough for me, so I waited a while then went with the D3 in July.

As for reception on the D3, it is amazing. My Ince would be between 75-85 in Houston (bigass city), but now I'm in Waco (tiny little ****hole, lol) and get constant 60's on the D3. So reception is way better.

Also, for the modding scene, there's 4 options right now. There's Steel Droid, Monster rom, DarkDroid (mine), and an alpha build of CM7.
