I suggest flashing CyberGR .v5 http://xdaforums.com/showthread.php?t=1425344

This is hands down my favorite ROM for the NS right now, and I'm pulling an easy 2-4 days/c now that I've worked out the few kinks.

If you do this, FOLLOW THE INSTRUCTIONS! :) they're actually necessary.
[Nexus S General] t3xboar:
herpaderp ben lol :D always the case eh? glad you sused out your issues.

So your old radio was what? and the new one that is bringing you these goodies?

@ densha99 - dude i know.. we clearly have nothing better to do than troubleshoot google problems :p
[Nexus S General] densha99:
Ben,

Thanks. I am just about to give that a shot. I just reset the battery stats and reset the OS. Newly charged battery from charger. The battery line is dropping like a stone. ~15% an hour. Can't figure out why the back feels warm when pretty much all services are off.

My Nexus One I can have it doing several tasks and all radios are on and I don't really notice it's temp going up that much.... Did you notice that about your NS?

I will give CyberGR .v5 a shot very shortly.

t3xboar

I know this has been said a million times. This phone at a baseline no root with nothing extra installed on it should just rock and roll with no drama.

And, I failed to post my software and model specs in my earlier post so....

2.3.6

UCKF1

[Nexus S General] ben.selinger:
Keep the AUCKF1 radio and flash CyberGR 5.

Enable CyberGR "power saver", Screen off data action = turn data off, data action delay = 0, Sync action = Turn autosync off with delay, and sync time interval = 15 minutes (or so), Screen-off wifi action = turn wifi off (I'm testing this one and it seems to be working now).

I'm considering leaving data on with screen off as I've seen 3d/C with 3g enabled FT, and it's nice to have immediate notification of gtalk msgs and such, but as I said, I'm testing right now. As it stands, this'll sync every 15 with screen off, and always sync while screen on.

Charge your phone to 100%, reboot and unplug. Do not wipe battery stats.

Last radio I used was XXXKB2 and it was teh sux. Switching to 2g resulted in losing radio till reboot. KF something resulted in some serious bugs with the screen :)

AUCKF1 is the only one I've found to be dead stable, of the 6 I've tried.

Android OS usage when Internet connection is on

Hello,

This days i used the phone without any sim card in it (not in airplane mode). It has the stock 4.0.3 ROM.

I fully charged it and left it in sleep overnight with wi-fi on, and it drained battery to 73% in aprox 12hours. Android OS consumption was at 43% and was awake for over 2:40hours. Wi-fi was 18%.

I've stopped the wi-fi and in the next 8-9 hours the battery was at 70%. The Android OS consumption is 39%, and awake time increased only with a couple of minutes.

I think that when a internet connection is active, the Android OS is making a lot of synchronization and maybe other stuff in background.

PS: GPS was on all the time. I've added also a screenshot

[Nexus S General] ben.selinger:
Try turning off wifi or setting wifi to sleep during screen off. You should easily get 2-3 days with this option set.
[Nexus S General] evcz:
I disabled many integrated services on cm9

3 gmail accounts, whatsapp, 3 twitter accounts, facebook messenger, g+

Data sync always on
[Nexus S General] densha99:
Not convinced the issue is software.

So I have tried just about everything and still my battery life was 4-6 hours with the phone on but doing nothing. No sync, no radios turned on, nothing.

Last night I took a battery that was 100% charged from my external Samsung charging dock and put it in my NS. I did not turn the Nexus on.

I left the phone alone, -off-, and went to bed.

This morning the battery was dead. :confused: I popped the battery out to reset the phone, put it back in and started charging it which allowed me to boot the phone and confirm that the battery meter was 0%.

I switched to a new battery which immediately booted up to 97% but started dropping at the same rapid rate.

My phone is losing charge when not turned on which means there must be an internal short somewhere in the phone (or something at a really really low level in the firmware?). I wonder if it's just mine.

Anyone with sub 6-8 hour battery life care to test this hypothesis?

[Nexus S General] densha99:
More testing

Since the hot-spot (Heat = Energy) on my phone develops right where the contacts for the NFC antenna contact points are, I am going to see if that is somehow related.

I have taped over the contacts on the back cover of the phone and will try another discharge test.

Fresh battery

airplane mode

wifi on

15 minutes sync on gmail

And the rest of the ICS and CyberGR 5 optimizations that Ben had recommended.

Based on past results, I should know something in an hour.

I will say that in looking at the iFixit tear down of the NS, that the radio AND processor are also right in line with that same location, so the heat could really (and most likely is) coming from one of those. Worth a test though since it's easy to check.

KC
[Nexus S General] densha99:
5h 45m

Right now I am pretty sure it's hardware. Here are the results with the NFC contacts taped over. Pretty much the same as before.

I will post the full dump when the phone comes back up, here is part of the drain. Very consistent drain with and without Wifi. All other wireless disabled.

[Nexus S General] t3xboar:
Well gathering all this info I actually compiled my own ICS rom with the basics working (bt, wifi, nfc, etc) then flashed the kb3 radio to my phone.

going to test on the pure oem self-made rom tonight to see what kind of drain. sometimes there is no better way to test than to make your own clean install that you know exactly whats going on :p

In short we have established that KB3 is probably the best bet for radio, and that there is a massive wifi drain. all the other stuff is gravy at this point and not really applicable.

Will post up my results :)

@ Densha - ya dude hate to say it but looks like your best bet is a warantee trade in... hardware is hardware. just bring it in and get a new phone. if you have drain while off then not much to do.
[Nexus S General] densha99:
Yes.... you are right... It's probably dead.

Cool, will be good to see what you come up with on a ROM cooked just to try to knock this issue down.

And I know, I know, it's 99.9999% a lost cause. I support these kinds of devices and when I find issues like this I like to really try to fix them. I just get to know the platform better.

The device was part of several Android devices I am testing but was my favorite and the one I "was" carrying. I got it unlocked / no warranty 45 days ago, so if I can't fix it, I will need to get another and just use this one for parts.

Just for the heck of it I flashed KB3 on it last night. Will run 2 batteries though it and do one more overnight test with full battery and power off. If no joy, I am in the market again.... Oh well..

Thanks again everyone for all of the input.

KC
[Nexus S General] tycruickshank:
A little off topic but do people feel like i9020 devices get better battery life than i9023 devices. I know the only difference is the screen and that darker colors on the i9020s would result in less battery drain but in real world use are the two roughly the same?
[Nexus S General] :
Anyone interested in battery should visit my thread and check the battery benchmark

For kernel benchmarks and more, see here: http://goo.gl/mpeHI
[Nexus S General] t3xboar:
They are about the same. it's hard to guage things like this because none of us have a 20 AND a 23 to put side by side. there are only so many tests you can do when one person has one phone and another has a different. it's impossible to make sure that the tests for that are duplicated 1:1.

I appreciate all the hard work that went into making the benchmarks, but this thread was more of using out the wicked drain caused by a rogue phone/app/ios/hardware flaw.

the kernels and variants are omitted from what we are trying to figure out here. but thanks ;)

************

K the cooked rom test is basically the nail in the coffin for me. its google that screwed something up royally. not our phones from the looks of it.

The rom I made to test was a clean 4.0.3 and -no- google anything in it. 0 gapps. basically the only thing it had once flashed to the phone was wifi/gps/BT/nfc/rotate + messaging phone call plugin and a browser. The kernel was the default compiled 3.0.8 built one.

without any gapps its tricky to activate the gps puck module, as it sleeps until something calls to it. reason i needed to include the browser. on google mainpage hitting places will call to the puck and turn it on properly.

so with everything ON, i was watching a battery drain of 5% per 2 hours about. I had started this test at work and by the time i got home, played around with turning the screen on and keeping it on for 5-10 min, then hitting power to sleep mode it etc..

I can rule out that its the phone itself thats messing up. Even when i was using the browser to jump here and there for a quick test, there was very little drain added.

In conclusiong the next test would logically be painfully installing/uninstalling every gapp on the vaccumed rom one by one to pinpoint the culprit after repeating the tests. :(

Something in all honesty im not going to do - but it at least gives a stepping stone to someone that wants to take the time :)
[Nexus S General] Ritwik7:
Hi everyone. I was doing some battery tests on my Nexus S for the past two days and I just stumbled across this thread.

I have a Nexus S I9023. Radio XXKI1. Stock ICS ROM + Kernel (official OTA update).

I charged my phone overnight and checked for battery performance with 3G enabled the first day and only 2G the next day.

Results with 3G on:
[Nexus S General] Ritwik7:
And Now with only 2G. Had just turned on 3G for a few minutes twice during the day.

3G signal strength is quite poor here with my carrier. So I thought that turning off 3G would significantly boost battery performance. Apparently not. Only about 13% better performance on 2G but with half the screen-on time.

Is this normal? Would switching to a custom ROM + kernel combination be any benefit?

And I must mention, NFC and Android Beam are turned on. WiFi was off throughout.
[Nexus S General] Alex~:
Looks like I'll be doing this test tonight, as my battery life seems dire at the moment. It all seemed to start when the ICS update bricked the phone. Had awful battery life on ICS, downgraded back to Gingerbread - but I'm still getting poor battery life.

What's the expected battery life for users with just 2G enabled, and wifi turned off, sync turned off, etc? At the moment the battery seems to drain to around 65% during the 8 hours I'm sleeping. My old HTC Hero seems to cope far better than that when it's acting as a 2G dumb phone! That lasts a few days with just 2G only and pretty much everything else disabled.
[Nexus S General] t3xboar:
This was my light test. basically just using the phone to make calls and text here and there - the following is

minimum

you should be achieving. I could have gotten another 6-7 hours until 1% if i didnt charge it after this.

The issue is gapps as per my previous post. there is a rogue somewhere that just ultra consumes battery like nobody's buisness. We just have to figure out which one.

EDIT: forgot to mention - minimum on ICS. on GB you should be hitting a week sunday to sunday without recharging.
[Nexus S General] Alex~:
Done a fresh ICS install earlier this evening, currently down to 78% battery in 4.5 hours. 2G only, not even bothered signing into an account (will restore from a backup another time), WiFi off, etc. This would result in less than 24 hours. :(

Will uninstall some of the gapps over the weekend and test.
[Nexus S General] morgadom:
After my tests I can also confirm that the problem seems to point to the radio instead of ROM. I had radio KI1 after upgrading with stock ICS, and had huge battery drains. After several ROMs I finally flashed radio KB3 and all my problems were solved. Running now CyberGR v6 with radio KB3, wifi off and switching to 2G when screen is off from CyberGR power saver utility. Excellent battery life now. Give it a try everyone thats having problems!
[Nexus S General] Alex~:
Fresh install of 2.3.6, XXXKB3 baseband, WiFi on, 2G only, pretty much everything else turned off, no Google accounts added. Barely used the phone, just checking it occasionally and a single alarm overnight to wake me up. Battery life of 24 hours without me using it.

Tried with WiFi off, same battery drain. Also tried 2.3.3, 4.0.3, latest CyanogenMod without any gapps installed, all seem to have similar problems.

Any advice on things to look for?
[Nexus S General] smorks:
i recently had a major problem with battery drain on a fresh install of a rom, and i found the culprit to be my APN settings. I am on the Rogers network, and for some reason in my APN settings, it was listing Chatr as the active APN. I also noticed the settings for the Rogers apn's didn't look right, so I deleted out all of the apn's, re-created the rogers ones, and the drain went away immediately.

FYI, I am using Codename Android 1.3.3 with Matr1x v16.
[Nexus S General] weedy2887:
I honestly have no idea wtf you guys are doing with your phones. I have pretty much always gotten 2+ days out of my phone unless I gamed for hours on end or ignored my phone completely.
[Nexus S General] Alex~:
Used to get more than 24 hours as well. :(

APN settings are fine - mobile data is mostly disabled as I tend to stick to WiFi. Put the phone into airplane mode to check the battery drain, yet again it's another 35% battery drain in 8 hours. Process list shows no problems, CPU Spy shows 98% time being spent in Deep Sleep, BetteryBatteryStats doesn't show any partial wakelock hogs either. I've attached screenshots which hopefully shows this!

I ordered a new battery over a week ago and that hasn't made a difference either. Was hoping that was the issue, but it doesn't look like it.

Anyone with any ideas on how I can diagnose the battery drain?
[Nexus S General] xzilem:
App

I got the same problem as you before but i already solve it. It seems my battery widget app and my weather forecast app is the culprit for the fast battery drain. Maybe there's some app doing the same thing to you too?
[Nexus S General] Alex~:
Wouldn't it either show in the battery list for processes or in BetterBatteryStats if a widget was using excessive resources?
[Nexus S General] kmudrick:
I would expect so. I got a sudden reduction in battery loss several weeks ago. New battery didn't help, factory reset, clean reflash of GB didn't help either. The thing would drain even in airplane mode, hell, strangely even when powered off.

Sent it to Samsung for repair, explaining to them the problem over the phone. I am pretty convinced there is a hardware issue here. Two weeks after shipping to them, I'm finally getting it back - with the dreaded "Solution: S/W UPDATED - PASSED ALL FUNCTIONAL TESTING". I'm not holding my breath that they fixed anything at all. I think the build quality on this phone is just garbage - really souring my first Android experience here.
[Nexus S General] Alex~:
I've kept on trying various different setups and left the phone in airplane mode - and still I get battery drain equivalent to 100% battery drain within 24 hours. Fresh installs, everything disabled, logcat shows pretty much no activity overnight.

I was hoping the phone would last me 2 years before having to get something else, but at the moment I've nearly given up on trying to figure out this issue.

[Fascinate Q&A, Help & Troubleshooting] SpinKix:
I live in a poor radio reception area, so I'm thinking of streaming internet radio stations over WiFi while doing yard work. Sort of a WiFi walkman.

An iTouch would work, but I have tons of android apps & games.

The galaxy player is nice, but that's kinda overkill.

So I thought a used smartphone would be a perfect choice.

One that has good WiFi range, and enough power to run games.

Nothing heavy gaming wise, I have a Nook Color running 99% of the games I like just fine, so anything comparable would do.

After looking around, the Galaxy S family seemed to be a pretty good choice, and lots of used Fascinate phones are on ebay for around $100.

So here I am, with a few questions...

Is the (Verizon) Fascinate a good choice, or are there better (or cheaper) versions from other carriers? Keep in mind I'm not ever going to use this as a phone, so even a bad ESN would work for me, right?

How about wifi range?

Are there any problems I haven't thought of.... if I flash something like CM7, can I run apps, media, etc. without Verizon ?

In other words, will this run apps, Market, like my CM7 Nook Color?

Is there a better place than ebay to look for one?

Any thoughts would be appreciated.

Thanks.
[Fascinate Q&A, Help & Troubleshooting] mvmacd:
Howdy!

First off, I use the Galaxy S Fasciante, and it is a pretty decent phone. I picked it up for $90 used, had some scratches on the screen, and dings, but not too shabby. [Ended up having to get the main board replaced a week b4 the warranty ended, but that is another story]

Unfortunately, from what I've experienced so far [owned the fascinate for maybe 1.5 months], my fascinate does not seem to do as well for wifi as my previous Droid X2, and, I am not sure, [Need to do a side-by-side comparison] my iPod touch 4.

That being said, I would suggest flashing either JT's vanilla GB, or maybe TSM Pool Party [I am still experimenting with the latter as of last week], because the stock is bloated.

You can still use the Market, Gmail, and all that by flashing the gapps package after flashing the rom. But if you decide the stock rom is good enough, I believe it should be fine as far as using it without a cell phone plan.

One thing though, if you wipe the data, and it's not on a plan, it will prompt you to "activate your phone"

Of course, it will fail, and will not let you into the os until it's active. So what I did when I was in this situation was look up the code to bypass activation. Just google "fascinate bypass activation" and you will find threads with the number you dial. cool beans

oh and as far as where to look for one, yes, ebay is fine, also you might check Craigslist. That's where I bought 2 android phones, and 2 laptops within 12 months.

and one more thing on the wifi, I am not sure if my wifi is just abnormally weak, or if that's how it is. anyone else care to elaborate how their wifi experiences have been? :D
[Fascinate Q&A, Help & Troubleshooting] SpinKix:
Thanks mvmacd, that's just the info I needed!

I just went ahead and ordered a Fascinate on eBay a couple hours ago.

Reading other posts, the weak WiFi was mentioned, but I'm hoping it's not a hardware issue, and can be improved with a ROM.

If all else fails, I might get by with dusting off an old Linksys WRT54G router and using it as a repeater.

That tip on the activation bypass is something new to me, as this is the first phone I've messed with. All WiFi tablets up till now.

I assume that only applies to the stock Fascinate, so if I flash CM7, I won't have to worry about activation, right?
[Fascinate Q&A, Help & Troubleshooting] neh4pres:
cm7 based Roms which were ported mostly by jt1134, have a lot of reverse engineering hacks for the phones hardware because there is no source code for that type of stuff. There are also Touchwiz based roms which run on the stock hardware configuration from Samsung, and are rooted, debloated, and there are kernels for those roms with voodoo Lagfix which make the phone about 3x faster than factory. It could have better wifi range with the stock hardware drivers than with jt's. With what you're going to use it for a Touchwiz ROM is best imho as the battery life was also superior when compared to CM7 roms on this phone.

Also the fascinate has very good headphone hardware, which supercurio turned into a audiophile quality experience with voodoo sound. When I move on to the galaxy nexus I will be keeping my fascinate for music.
[Fascinate Q&A, Help & Troubleshooting] SpinKix:
Wow! you guys have given me a lot if good info.

I'm getting a clearer picture of the Fascinate/Samsung hardware ROM development now.

Like I said, I'm new to phones. Different animals from the WiFi tablets I'm used to (Viewsonic Gtablet and BN Nook Color).

I'll look for a Touchwiz ROM with lagfix then.

BTW, other posts concerning the weak WiFi mentioned an app called WiFi Fixer.

Looks promising. Lots of positive reviews.

Makes me wonder, does this have to do with the ROM choosing to switch to 3G, and apps like WiFi Fixer just lock on to WiFi?

Maybe I'm cynical, but knowing Big Red, maybe their software is partial to a paid data plan over WiFi.
[Fascinate Q&A, Help & Troubleshooting] sol_671:
My Fascinate has a weaker signal.compared to 2 of my iPod touch 2g and 4g, My iPod touches would have 4 bars while my fascinate would only have 2. Never tried using any app or hacks to boost the signal since I use 3g but I know that EH03 gave me better signal as a phone compared to the older radios.
[Fascinate Q&A, Help & Troubleshooting] neh4pres:
Also. If you want to pack a sd card full of music, and don't care what version of Android you have. I will suggest the dj05 superdark ROM. It is eclair "before Froyo". But I would go a full 8 hour day at work listening to music and still have 80% battery when I got home. wifi would drain a little faster, but any ROM in the dj05 service release is well known to have seemingly impossible battery life. at least by anyone who had the phone that early. If it was not for the want of running apps that require newer versions of Android I would still be on that ROM.
[Fascinate Q&A, Help & Troubleshooting] mvmacd:
Yes, you probably won't need it, but just for reference, here's how to bypass activation on stock rom:

press emergency call button,

then at the dialer,

press *#83786633,

then press the Home key

As far as the rest of the roms, I do believe the other roms have a "Skip activation" button, so you do not have to worry about it.

Oh, one more thing. Developers are working on an ICS port [Android 4.0] for the fascinate! They released Build 6 just two days ago, and I am seriously considering trying it out. :)

edit: the ICS rom is epic. Not sure if I am getting worse battery life or not, but it is stable and looks way cooler.
