[Nexus S Q&A, Help & Troubleshooting] richstant:
Hi, can anyone help me solve this problem. I'm getting poor battery life from my Nexus S (stock 4.0.4) & android OS using a lot of battery. I've narrowed it down to WiFI - when I turn WiFi on, the battery depletes much faster than when I'm on 3G & android OS goes from ~7% to ~20% in battery stats. This is the opposite way around from what I would expect based on other posts, which say that WiFi uses less power than 3G. You can see the effect in the screenshot - for the entire time on this screenshot, I was at work with good 3G coverage & the WiFi point is right outside my office:

Any suggestions?
[Nexus S Q&A, Help & Troubleshooting] unlinker:
I agree with you, stock 4.0.4, Matr1x kernel (but I get same results with Air kernel too) and wifi always on = poor battery life.

My workaround is keeping it off and switching it on only just before an autosync or when opening browser/Gmail (I do that with Tasker)
[Nexus S Q&A, Help & Troubleshooting] XxLostSoulxX:
When WiFi is in use what are you doing?
[Nexus S Q&A, Help & Troubleshooting] richstant:
Essentially nothing. I checked the odd email, but for the most part the phone was in my pocket doing nothing.
[Nexus S Q&A, Help & Troubleshooting] Aktifit:
have you got a background service that only runs on wifi?

also, in my experience, 3g only uses more battery when you're actually receiving data (e.g. browsing, data sync).

to me your battery stats don't look that bad, so my theory is that because you don't use your phone that much, anything that uses just a little bit of battery makes a big difference in battery use percentage.

but then again, I could be completely wrong...
[Nexus S Q&A, Help & Troubleshooting] XxLostSoulxX:
Well one thign is for sure battery will always die faster on the network because most of the time if your in bad service areas it trys to fight for service therefore shi**ier battery life.

But @ Richstant do you disable mobile data manually like. For example because my NS4G is just deactivated on my Epic 4G i manually disable data and re enable when i use something so i save battery life.
[Nexus S Q&A, Help & Troubleshooting] ykphuah:
I switched my sleep policy to while plugged in now. The difference with just switching the wifi on and off is really insane for me.
[Nexus S Q&A, Help & Troubleshooting] Harbb:
The way WiFi works while screen is off is hopeless on the Nexus S. I think it may be exagerrated because of the guzzling hardware as it seems no different on the GN or SGS3, though they dont drain nearly as much (i thought otherwise at first, unsure if it's on a phone-by-phone basis though). WiFi likes to stay on even if you set sleep policy otherwise - look at it funny and it will stay on and drain. This is something that i hope will improve in JB, but i doubt it. For now, best bet is set to Never (or plugged in, same effect) and switch it off manually if you won't be using it for long periods of time.

WiFi uses less power for large amounts of data and even browsing. It's faster, it doesn't need to send extra power and there is less thrashing to find the best signal. Data, however, is technically always there anyway as the radio is always powered, so if it only needs small amounts of constant data, it is often better for battery if you have good reception. This is one thing we i don't think we'll be worried about in newer phones, thankfully.
[Nexus S Q&A, Help & Troubleshooting] richstant:
Reception is good, mobile data is on all the time.

I'd forgotten about that setting, I'll try it now. In the past it's not worked for me though - the WiFi just stays on all the time no matter what.

Thanks for the info - sounds like it might be just the way this handset is :-( I don't remember it being this way under gingerbread, the WiFi turned off properly when it slept then, and battery life was much better.
[Nexus S Q&A, Help & Troubleshooting] XxLostSoulxX:
I'd still disable the mobile data even regardless of how good the reception is it'll still save you more juice in the long end
[Nexus S Q&A, Help & Troubleshooting] allevolve:
You don't have any apps set to auto-upload or backup anything (e.g. Dropbox Camera Uploads, G+ Instant Upload) once it connects to Wifi do you?
[Nexus S Q&A, Help & Troubleshooting] ykphuah:
Hmm, that option worked fine for me, when I unlock the phone, there's a 1-2 second delay before the wifi icon comes up, if I am not plugged in, that is.

I have latitude on all the time, I am suspecting that latitude is the one that causes my battery drain WHILE wifi is on, since there's just too much wifi hotspots around here, and if latitude is triggered everytime there's a new wifi hotspot discovered, then it will have a lot of updating to do. Using the sleep mode doesn't cut down the number of wakelocks (reported by BetteryBatteryStats) that those LocationServices triggers however, but battery life does seemed to be saved, especially on the days where I rarely use my phone.
[Nexus S Q&A, Help & Troubleshooting] Harbb:
I would look at this also. If there is an app that has some connection with wifi (i think this would be done through intents but i'm not very familiar), it may either keep wifi on or awaken it from sleep periodically (where it looks like other apps/features take over and continue using it instead of shutting it off immediately). Maps and something from Android OS or Android System seem to be main culprits if the battery page is to be believed. BetterBatteryStats can help, but haven't gained that much information in regard to wifi - though is priceless in most other areas.

Edit: Didn't see the last post (got distracted lol). That could be it. Note that in BBS you should also look at the number of wakeups, not just the time wakelocked. Obviously you can rack up a lot of wakeup attempts and still show only 1s of actual wakelock, but it adds up immensely from there - particularly when some other apps are triggered because they are notified wifi is temporarily "active" when it shouldn't be. Also, these are my experiences and not coding fact, so take them with a grain of salt and listen to those wiser than I ;)
[Nexus S Q&A, Help & Troubleshooting] richstant:
Well I'm pleased to say I got a serious improvement in battery life by setting wifi to off when not in use (except when charging). I tried that under 4.0.3 & it didn't work, but it seems to work correctly under 4.0.4.
[Nexus S Q&A, Help & Troubleshooting] xfeejayx:
wow, I didn't even know there was a "wifi on during sleep only when plugged in" option. I knew juice defender and other similar apps did something like that, but didn't know it was built into ICS (or CM9 :D)

thanked for the tip
[Galaxy S II Q&A, Help & Troubleshooting] ulftorpe:
Hallo everyone!

First of all - I got myself a smartphone just yesterday for the first time ever, so yes.. I'm even less than a Noob.. you can call me noob^2..

Second: i searched the forum but I did not find a similar topic. Either there is no similar thread yet, or I don't know how to use the Forum search engine properly.. If so, please excuse!

I have a SGS2 i9100 (not G) and android 4.0.3. Not rooted (don't know yet how to so..)

I would like to replace my ipod with the SGS2, but the soundquality is very poor. I would like do connect the phone to an usb DAC (fiio E7 for example), but i read that it is not possible to bypass the internal crap yamaha-DSP. So is there any possibility, hack, or whatever, to send the pure, unprocessed mp3 data to the DAC via USB OTG??

Thank you a LOT!
[Galaxy S II Q&A, Help & Troubleshooting] MistahBungle:
Not currently possible with the SGS2 & highly unlikely to ever be. Devs who have been asked to have a look at it have all gone 'Nup' because of Samsung's proprietary/closed source drivers & so on. To give you an idea of what devs are up against/why nobody will tackle this, read this post.

Only way it will ever happen is if you code it yourself, or a dev with a lot of time on their hands (there aren't really any of these; the development they do now is done in their spare time & on top of the jobs they have) who actually wants to use this themselves.

Don't ditch your iPod.
[Galaxy S II Q&A, Help & Troubleshooting] ulftorpe:
Well, that's a pitty!

I read somewhere that android 4.1. (Jelly Bean) supports that USB audio out capability. Is that true, and does that mean, that if I could install jelly bean on the s2, I could use usb audio?

Another, probably stupid, question. Is it possible to install the 'not touchwized' - original - version of android on the s2? Would that make usb audio work, or is it a matter of hardware and drivers??

Thak you for your reply!
[Galaxy S II Q&A, Help & Troubleshooting] MistahBungle:
Hardware & drivers. Won't work no matter what. Unless a dev makes it work as I said in my previous post.
[Galaxy S II Q&A, Help & Troubleshooting] ulftorpe:
So right now, no one is trying to make the s2 work..? Would donate if someone succeeds..!

What about the Galaxy nexus phone and about the Galaxy s3? Do these phones support usb audio, even though they are from samsung?
[Galaxy S II Q&A, Help & Troubleshooting] MistahBungle:
1) No, offering money won't make any difference. There have been threads made in General where people have pledged differing amounts of money; in one thread I offered $20, all up maybe 6-7 people pledged money totaling around $150 to get it working. No devs took up the offer. Seriously, this is something that is very difficult & time consuming to get working, it's not simple like some people seem to think. It just isn't going to happen. Money isn't the issue, the issue is time and/or a desire on the part of a dev to use this feature themselves. No dev so far has had either of those nor a desire to get this working.

The fact it doesn't work on stock roms should tell you something.

2) You're asking in the wrong place, ask in the forums for those phones.
[Nexus Q Q&A, Help & Troubleshooting] ocran:
Unfortunately my amp (NAD C352) does not have an S/PDIF in, does anyone with a Q that is open right now tell me if they can easily extract the analog signal before it is amplified?

From the pictures I have seen, it looks like there is a ribbon cable with 5 pins that connects to the amp, which looks to include a TI chip (can anyone find the part number?). I assume that the signal is still digital in the ribbon cable and I will have to extract the signal from the PCB(Assuming that TI chip is indeed the DAC).

Edit:

Here are a few more details: wired.com/gadgetlab/2012/06/nexus-q-teardown/?pid=3468
[Nexus Q Q&A, Help & Troubleshooting] bobukcat:
You could always just use a cheap (<$20) digital to analog converter box. I haven't taken mine apart and hopefully don't find a reason I need to. :-)
[Nexus Q Q&A, Help & Troubleshooting] ocran:
Yes, something like monoprice.com/products/product.asp?c_id=104&cp_id=10423&cs_id=1042302&p_id=6884&seq=1&format=2 would of course do the job, but I imagine that the DAC in a $20 part is less than desirable. Perhaps I should invest in a preamp(or receiver) that accepts S/PDIF...
[Nexus Q Q&A, Help & Troubleshooting] bobukcat:
Valid point - I have a bit of a similar predictament in that I would like to be able to send the Q music to zone two buy very few AVRs support Digital Inputs to zone 2. I wonder if the options for converting speaker level outputs to line level (mostly for adding amps to factory car audio systems) would be cleaner or not. May just spring for a new AVR too, even though the one I have is only about 5 years old.
[Nexus Q Q&A, Help & Troubleshooting] ocran:
I didn't even consider that an AVR wouldn't be able to send a digital input to zone 2(or 3). I'll have to make sure that is the case when I finally break down and pick one up.

My current setup is almost laughable, I've taken my 7.1 sound card and split it into three independent stereo cards for which I use MPD to output to three analog amps to obtain my three "zones". Consolidating to a single receiver would save a lot of space, and idle power(which is huge; the C352 pulls over an amp when not in use).
[Nexus Q Q&A, Help & Troubleshooting] bobukcat:
Yeah, you have to go up the line quite a bit to find an AVR that will send digital inputs to a second zone. Denon, Pioneer and Yamaha (probably others as well) all make one but the cheapest I've found (in limited searches) is about $900.
[Nexus Q Q&A, Help & Troubleshooting] ocran:
That $900 one must not have been a Denon. The AVR-2313CI ($899.99) nor can the AVR-3313CI ($1999.99) do it. The AVR-4311CI ($2099.99) can do it with the following conditions:

• When the input source to which the digital input connectors (OPTICAL/COAXIAL) are assigned is selected in ZONE2 or ZONE3, playback is only possible if the digital signal being input is in PCM (2-channel) format.

• It is not possible to play the digital audio signals input from the HDMI or DENON LINK connectors in ZONE2 and ZONE3. Use analog connections for ZONE2 or ZONE3 playback.

Which warrants the question is the Q's TOSLINK PCM when playing music?
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] mrtim123:
Hey all,

new to the GNote forums, but been playing with android for some time now.

Just needing some tips on the way to gain rooted GB on my note.

im not super interested in getting ICS yet....but could be swayed ;)

From what i can tell, i need to odin flash a pre-rooted gb rom (in particular an LC1 version of the rom) and then to flash a LC1 version of the kernel to suit. Sound about right?

My current plan is to

1. flash LC1 Open Europe from http://xdaforums.com/showthread.php?t=1535025 with PC odin

2. flash LC1 kernel from http://xdaforums.com/showthread.php?t=1331784 with flasher included in download

3. enjoy rooted phone.

My phone is currently stock (only got it a day ago) and am on Optus in Australia. I am running the following spec according to "settings/about phone"

Android 2.3.6

BBand N7000XXLB2

Kernel 2.6.35.7-N7000XXLC1-CL1003701

Build GINGERBREAD.XXLC1

does my plan above sound right for this phone?

I'm well versed in flashing phones, but coming over from the X10 its a very different technique and there are lots of different files to match up that im just not 100% on yet :)

cheers guys, already super happy to be a samsung user - love the note!

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] cheryanne:
I have a French note from Kogan that I've had for a couple of months. I just updated to ICS via Odin last night and then rooted it. I'm on Telstra here in oz. It seems ok and the internet seems faster and more stable but I'll know more after a full week of use. Its my first Samsung so although I had rooted phones before I was a bit nervous about using Odin and the brick bug terrified me.

Sent from my gnote as always :)
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] TempusFudgeIt:
Yes your plan sounds right - follow Dr Ketan's thread in the Development forum.

I bought a Note via UK - turned out to be Polish (it was one of the first released last November). I rooted it using Zergrush then always used CWM, so while Odin works I prefer to use Clockwork Mod as I can do all the flashing on the phone.

Some other things that may help..

I'm on Telstra and never (touch wood) had any modem / Nexg G/Wi-fi issues)

On Gingerbread I found AbyssNote kernel to be one of the best (everyone uses 4.2 version when flashing to ICS so you may find it useful to download) Not sure what my original baseband was but have used others and they all seem to be ok - maybe I'm just lucky!

Also Rocket Rom on Gingerbread and ICS seems to be reliable as well.

So if you feel the need to ICS - use the above kernel and ROM and follow instructions on RocketRom OP.

Haven't found a dedicated kernel or firmware version for the Australian Note, but since I'm on Polish one so far everything seems to work.

Good luck and welcome to the wonderful world of the Galaxy Note - had it over eight months and never tire of it :)
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] mrtim123:
thanks guys!

i took the plunge the other night - i figured that i had read as much as i could read and just dove in.

First up i Odin flashed a pre-rooted rom (LC1).

That was nice for a little while, but i wanted more ;)

I then flashed the CF Root kernel on so i could have CWM. This was nice, i was able to take a nand backup so i could always go back to stock if i needed to.

Now, i was getting the hang of the methods for this phone. I used CWM to flash on CheckRom v6 (GB) but i really wanted to go for ICS.

I read that as i was on a non standard kernel GB rom, i could go straight there. Guess what? thats what i did next :)

Im currently running Paranoid Android v0.5 and am loving it!

Loving the Note, it makes my work iPhone 4 feel more and more redundant each day :)

Hello all. I just got a sgs2 t989 and on have it on stock ics rooted. I flashed the latest cm9 (nightly) since cm7 is not available for it. It flashed correctly but it stays stuck on the boot animation. I re-flashed, made sure i wiped data/system/cache/dalvik and still nothing. It just stays on the boot animation (i left it there and it stayed there for an hour)

I have rooted and installed custom ROMS on other phones and never has this problem

[Galaxy S III Q&A, (US Carriers)] Bfitz26:
were you running a ics rom or was it gingerbread while using it, as it could be incompatibility issues with ics...
[Galaxy S III Q&A, (US Carriers)] M4gicM@:
Yes, I know you may think this is a duplicate of how to disable the wifi popup. It is not. I know you can use anycut to disable the link to HiddenWifiPopup or whatever but that is not the question.

The questions is, does the setting under Settings > Wifi > "Notify Me" work?

For the verizon the pop up will still appear, even when notify me is disabled. Is this a bug or is that how it is for all carriers?

If it is a bug I would love to try and fix it in a more legit manner then using anycut.

Hello,

I've been using CM7 and now CM9-NIGHTLY-120711-Defy ROM, but, frankly, the phone is next to useless. The system/ROM on my phone is slow, unresponsive, buggy. So before I make crazy moves (like buying an old iphone) I would like to ask you for advice.

Is there any Android 4+ ROM for Defy that just works fine? No slowdowns, usable HWA, responsive... I really hate Motorola for not unlocking bootloaders (and won't buy any Moto ever).

I will very much appreciate your help. I cannot switch phone now (actually I've got two phones, one is Defy green lens the other Defy red lens).
