huge power consumption - 8525, TyTN, MDA Vario II, JasJam General

Hello to everyone in this great and very very very big forum.
I just bought (1 week ago) a tytn from somebody. It looked very ok, the software was good when i tested it when i bought it but...
The phone went off in no time (I didn't noticed this when i bought it) like 3-5 hours.
I installed acbPowerMeter and BatteryStatus and something VERY STRANGE happens:
with wi-fi OFF it consumes something like 350mAh (not 35, but 350!!)
with wi-fi ON it consumes something like 150mAh (I have to be connected to a network to consume like this)
When i put it in stand-by it consumes something like 100mAh (but it can consume even 300mAh in stand-by).
This consumption i told you is with the phone OFF! with it on it consumes something like the same or less.
I want to ask you: is there anything that i could do (software change...) or is a hardware issue? Because it is obvious this was the reason he sold it and i think he tried many things too... (now he doesn't answer his phone, of course)
Details for my tytn:
ROM version: Schap's 4.31 (WM 6.1 I think)
ROM date: 10/03/2007
Radio version: 1.47.30.10
Protocol version: 32.80.7020.20W
ModelNo: HERM200
Clue:
He said he sails it because he wants tytn II and that the wireless connection drops now and then (he said 1 time in 2-3 hours) and i said ok no problem for me (he used it like a wi-fi card for his laptop)

No reply from you too?
Oh well... I think I have a curse for second hand things...
Ontopic:
The phone heats very very strong and after a call it consumes much memory even with wi-fi on. Turnin the phone off doesn't resolve the problem.
I'm thinking on hard-reseting the device to see if it is from the ROM (it will be back with win mobile 5, no?)

Hahahha. Welcome to the TyTn club.....
The power consumption is the problem with all the Windows Mobile phones I have tested. I have tested about 15 different phones for my work.
HTC is probably the best for power consumption. Why, I think because you can disable WiFi, HSDPA and BT and IR. Then you can work for more than 50 hours with you're same phone!
Have FUN with you're phone.

Thanks for the reply but read carrefully:
When Wi-fi is TURNED ON it consumes LESS!!
This is very unusual. And the power consumption for 300-to 400 mAh when i don't do nothing... the word huge is little word for the comparison.
if i have at least 20 hours of stand by i would be very pleased about this ppc... but i don't go more than 5 hours...

Hi shumilica, and welcome to the world of winmo.
Power consumption has always been incredible on my Hermes, which I've owned for about a year and a half. Of course, my device is on an unlimited plan, and it checks 5 email boxes, 4 of them every 30 minutes, and the other on push. It also updates weather in 4 cities every 30 minutes, and downloads newsgroups once a day.
Left on its own, my battery will die in about 3 hours. That is why I have 2 batteries, a docking/charging station at each of my desktops at work and at home, a charger on my nightstand, and one in my car. These things need a lot of fuel to run.
I can't comment on your strange findings with wifi ... are you sure you trust the numbers being reported? Does your battery life REALLY improve when wifi is on? Or is it just that the numbers being reported are higher? I'd question the software you're using to generate these reports.
As for hard-resetting ... no, it will NOT return you to a previous ROM. That's not how it works.
Hope this helps,
-pvs

wow my tytn saves me a whole lot of power compared to yours mine uses between 30 and 52mA with wifi off with wifi on it uses 150 to 400mA but before i updated the rom to wm6.1 it was useing a whole lot more try updating the rom but save all your files

To the OP, FIRST backup all your stuff then try flashing a STANDARD WM6 ROM to the device...such as the HTC official WM6 ROM.
Do a test with the power meter app and see what happens.
Come back to us with your findings. Im doing some tests of my own at the moment to see if the battery status is updating correctly in my ROM (i use the one that displays the battery % in the graphic).

also use a taskmanager to see if there's anything using a LOT of processing power all the time (CPU)
My phone is only GSM only, with specified bands(so, not in auto mode), and uses less than 90mAh with the backlight turned on, on the today screen.
WM6.0 & Radio 1.47.30 by the way, best in my experience for battery consumption and stability of voice calls. My apartment gets this really crappy antenna and it's a REALLY good stress test for radio versions. A GOOD radio will be able to hold an understandable voice call. An average radio and sub-par radio will have a lot of hiccups

where can you get HTC official WM6 rom from? does it get rid of orange stuff?

hey guys,
i wantet to post the same problem! its my second tytn (first went swimming ...) and this new one (buyed second hand too) has the same problem but i just noticed it is runnig very hot and empty within 3 hours(just in standby). Now i checked with acbmeter (without anything runnig any apps) avg. 350 mAh, with wifi on 84mAh and its quied cooler. My last tytn runs a whole weekend, without charging. I am new with this whole flashing thing where i can get this radio 1.47.30?
regards
FFKangoroo

hy guys,
i have the same problem...

Did you ever get around to doing tests on this? I have a feeling that my battery meter is actually reading incorrectly (as opposed to the battery loosing that much power). I say this as I have seen a number of times, as an example, battery at 60% would drop to about 20-30% after only a 15-20min voice call. Also, after soft-resetting the device the battery meter would increase to about 20% more than before the soft-reset.
I'm definitely a converted user of WM devices- been about 4 years and love them but this Hermes is really testing my patience with battery life!

I have to tell you what happened with my tytn:
I changed the ROM but still no change, the back cover was heating and the battery was out in something like 5-6 hours top. But one time, i don't know why, after it drained, i kept it off and wihout battery a week or something and I puted the battery back and NO MORE battery draining... two days of stand-by (without sim) and was at 90%. I shut it down and reopened (or putet in the charge, I don't remember very well) and again it started again... After that I tried a lot of different combination: drained the battery, pulled out the battery for 1-2 days, charged it with the tytn closed etc. etc. And after some more drainings... IT STOPPED... so after this my tytn didn't drain the battery anymore so quickly, no more heat in the back cover (from the battery)... and i tested it: i closed it, reopened, charge it for a momement, put a sim in it, speak with it etc.
I think it helped that i had bluetooth always on... but i don't know for sure... so... try keeping bluetooth on (put it always on from the settings), the tytn will drain the battery, charge it with it closed, open it and the bluetooth will be still opened and maybe it will work... or maybe it was from the fact that i trow it many times in my bed So...
I tested it for 3 days with no problem and after that i sold it.

i my cause not function...another solutions?...recomands?....

After having a think I bought a new battery and it WAS a dodgy battery. The new battery isnt an extended one (it is 1500mAh instead of 1350mAh but thats the only difference).
The device will sit there nicely for days before needing a charge, depending on if i use it alot or not, push email is on and i tend to get atleast 10 emails a day, several calls etc...

Perhaps something I may have to try too- I've have to turn off direct push and schedule emails (exchange and personal) to two hours and the battery life is still poor.
Will look into a new battery to see if that helps. I've had my device coming up to two years now.

Yes mine is almost 2 years old, I bought it around July/August 2006 when they first came out.
The battery I bought on ebay is HERE. The guy delivered it VERY quick (im in the UK).

i've charged it completely, it obviously got really hot. usually at this point, i would take out the battery and let it cool off before turning the phone on, otherwise it would get even hotter and eat 300+ mA and drain the battery fast. this time i opened the wi-fi connection and immediately the battery status dropped from 332 mA to 130, and stayed down there. the phone even cooled down a bit. after i've turned off the wi-fi, it started draining and heating again. what can i do? is it a software or hardware problem?

yep i flashing all the coocked roms found this huge forum and....same problem

Battery drains unbelievably fast!

Please tell me if anybody else is experiencing the same problem. If it is just me i wont replace my ppc and find solution for it. If everybody else is going through the same problem i will ditch this.
I mean my older ppc which i have had for two years lasts longer than this. I haven't even inserted my GSM card, nor used wifi etc. And whats more it requires such a long time to get the battery fully charged.
I have updated my roms as you can see below:
Rom Date: Jun212008
Rom Version: MP-1.01.04
Bootloader: MP-1.00.03
...but battery still drains like mad.
I have searched here but not found any solution.
BTW how do you turn the screen to off completely. When i manually turn off the display i can still see light coming off of the screen. My other pocket pc's turns dark completely. This is at my desperate attempt to save power.
Currently I'm turning off the keyboard as well as the SmartWheel, yet another attempt to see if power is conserved. So far it is showing signs that it is. Will let you know tomorrow. However the backside of the ppc still gets heated up considerably more when compared to my other devices that i've had.
How to solve this? My ROM is even more recent than the one posted on HP's website! I really love everything about the Ipaq 612c except this battery issue.
TIA
i suggust you either try other rom or contact hp for exchange, there is known issue with battery for some ipaq 61x
I had the same problem with my 614C.
The battery started draining really fast even without use and another symptom was that it would no longer connect to active sync through the cable.
I had no idea what caused it and it was exchanged by HP.
A week after that I connected the phone to my car adapter (12volt to USB) and the same problem came back. Once again it was replaced by HP and the adapter is in the trash.
I belive there was somethinh wrong with the adapter that caused some electric damage to the phone.
hello to you both,
So does this sound normal? Using programs like AE Button and B_Uptime it says that i have around an uptime forecast of 5 hours and 7 minutes.
So far i have used 1 hour and 40 minutes. I have another 3 hours and a half left.
Does five hours of usage sound normal for a brand new battery?
Anybody else can get more uptime out of their system without underclocking it?
Maybe you have ActiveSync always running in background?? See in processes repllog.exe file.
no replog.exe in processes registering zero percent usage.
How about you, how long does power last with your 600 series ipaq? Does the battery get hot also?
mines lasts 3 days with normal phone use (probally lite compared to others) music playing for about 2 hours a day and GPS for maybe 30mins a day, after 3 days i'd have at least 30% battary. Screen on setting 3 (which is almost the same as max anyway) not much wifi/bt though, its a 612c as well.
since you've posted other problems as well i'd ge it changed.
[edit] i get some heat only with the gps and after an hours of continuous music. otherwise its rather cool
Using a registry editor on the Pocket PC add a new DWORD value of DisablePowerManagement with a value of 0 to the following keys:
HKEY_LOCAL_MACHINE\Comm\L2TP1\Parms
HKEY_LOCAL_MACHINE\Comm\PPTP1\Parms
After saving the new DWORDs, turn your phone off for 10 seconds, and then press the soft reset button. Once the phone reboots, you should see a noticable improvement in battery life.
This battery saving trick has been used successfully on many WM devices...
Glad to hear that guys...
I will show this to the people at HP at i'm not B**lsh*ting.

The battery looks different to the one that came with my 612c is white allover. This one is not HP made? But lasts longer?

No, it is an aftermarket battery.
Lasts longer then the original HP, I have one about 1 year.
if anything that battary would last shorter than your current battary (assumeing your current battay is not defective) The ebay one is only 1500mAh while the stock HP one is 1590mAh.
But if you only get say half a day on a single battary, two should last you a full day.

I am trying this now... Will let you know how much it saves power.
But something is strange with this Pocket PC. I use a program such as B_uptime to see how much the device has running and how much it has been idle. (See picture)

When i press the power button to turn it off it doesn't generate ANY idle time. It seems that when i press the power button the some processes are still active. In this example I have only 2 hours of usage time left.
But with my other Pocket PC, which I have the exact applications installed and exact applications running, if i press the power button, idle time is never zero. So for example in a day i would typically have five hours of Processing Time and Five hours of Idle Time. Not so with the Ipaq 612c.
This is definitely what's causing the PPC to be warm even when i'm not using for it for hours.
I use ROM by Yevg001 with FW 0.89.
When I disconnect my active sync. I have set an application to automatically kill active sync. When checking processes, replog.exe is not running.
So what gives??
b_uptime can be downloaded here:
http://freewareppc.com/utilities/buptime.shtml
found the problem
I have found the bloody culprit!!!
Do not install SPB Phone application that came with your phone.
UNINSTALL IT IMMEDIATELY!
Now when it's turned off, the processor really sleeps
strange, i use SPB shell and have not noticed any battary drain. The before mentioned battary life was with SPB shell running. I too use Yevg001's rom (1.4 rev2 to be exact) with FW 0.89.
strange indeed
all is o.k now...
I now just have to check the battery problem where the ppc resets its self (or turns off by itself) when calling or receiving a call when the battery level is below 50%...
If that happens then i'll get in touch with hp tech support...
thanks to all...

No Not SPB Shell but SPB Phone and not the latest version. The version that came with box, the older version.

CPU clock speed

Hi.
Because of huge battery drain (with only receiving approx 30 SMS, 10 minutes incoming calls, no work, device OFF on night, and always with display off) it lasts only max 2 days (except night!) I am searching a way how to save the battery. First of all I wanted to downclock the CPU. 528MHz is too much for my use. Only app, which seems to work for me is nueClockControl. However it should support the command line parameter, I was unavailable to do it.
When I create a shortcut with "\Windows\nueClockControl.exe 5", it does not work. The Nr. 5 means a CPU level, which corresponds to 256MHz, which is sufficient for my needs.
So I have to downclock it manualy after every boot up. The nueDynamiClockControl does not seem to work for me. Instalation pass OK, after boot up, there was its process running, but the CPU speed (checked via nueClockControl) was still 528MHz. I was even unable to find the program in start menu - I dont know, how to change its settigs. When I start it manuly from windows directory, nothing happens.
Moreover I tried the BatteryStatus, showing CPU speed (and more) on Today screen. But it shows 553MHz instead of 528!!! Dont understand.
So finaly my question: Is it possible to automaticaly or manualy via link downclock the CPU speed?
Thank you for reading my long long text
I read somewhere on this forum that over/down clocking is not avaible in topaz.
Topaz won't work well on nueDynamicClock...
I installed this before and it drain very fast on media playback...
So I hard resetted and keep this soft away... and the phone act normal again...
2.5hr of audio/video, 5-6 SMS, 15mins call, wifi 35mins, play here play there... this thing can survive 1.5 day (100% to 30%) before reach for charger...
Doesn't the CPU have several power states anyway? It would surely only use full speed (528MHz) when needed, most of the time it would be idling at a lower speed. So, even if you could "underclock" it, it wouldn't make much difference.

If it has its own pover management, it does not work. I use my device very very abstemious. Yesterday evening it was fully charged. I did not turn it off during night (used it as a alarm-clock) only the phone-radio was off of course.
During the day I received and deleted about 20 SMS. Received 3 calls which last together 5 minutes. And one instalation of application. Its about another let say 5 minutes including settings of the application installed. Now I have only 33% of battery. So in the evening, about 24 hours after full charge, it will be dead again. So even if I dont use my PDA as normaly a user should, it can hold only ONE day max.
Pretty ****ty machine
And if I try ROM with 6.1, warranty void...great
I worry to touch it, to keeps its battery alive, if my wife or children need to call me.

You should be able to try a 6.1 ROM after HSPL using OliNex 1.83. Take a note of your present ROM first, and check it's on the list here http://wiki.xda-developers.com/index.php?pagename=Topaz_ROMs_Shipped. Then, if it doesn't work out you can reflash your old ROM and restore the bootloader code back to the original using the OliNex SPL relocker.

That's the same ROM I use, it's very good, lean and quick, not many bugs. I can't understand the GPS problem. My GPS is very slow from a "cold start" (10mins+), it appears to not work, but it does eventually, & it's been the same for all ROMs I've tried.
You might try a hard reset, there's a recent thread which suggests this is helpful after a ROM change, though I've never needed it myself.
Try the app HTC GPS Tool, it provides quite a lot of technical information, including the data stream from the GPS receiver. You have to keep selecting "Q7200" as GPS though, it keeps defaulting to "SIRF" when launched.
maybe you could also try update your radio rom, this may help your GPS problem and also could improve your battery problems

Yes, I had to do the Hard Reset (even if I did it after flashing and first boot), now it works with no problem. It works even immedieately just after the boot.

Will test it. Started to work (customize new WIN and application) this morning. Fully charged and after hard reset. I playd with it whole forenoon and now I got 46%. Do not if it is a worse or better, because I used it realy intensive. Now I have it fully customized to me needs, so no "hard work" on it will continue. After the battery drops so the device will be unable to even boot, I will charge fully the battery. Then I will see, how long will it last.

You will ruin your battery doing this!
How do you treat the phone as far as charging goes generally?

It shouldn't ruin it, the battery has built in discharge protection, you can't discharge it completely to the extent that it would harm it.
It's quite good to completely drain it sometimes to allow proper calibration of the battery meter. I wouldn't do it regularly, though, as I believe LiIon or LiPolymer cells last longest when recharged before they run down completely.

Sorry to say this but you are completely wrong.
You can most definitely harm it.
Calibration, discharging or cycling of any sort impedes the chemical properties of Lithium Ion batteries (as well as Lithium Polymer) and believe me it's not my opinion, it's fact.
The cutoff circuits are for safety protection not to assist in correct maintenance or charging usage.
There is only one way to treat them and that is to charge them as often and for as long as possible. Never switch them off. They really do like being treated that way.
If this is nor done from day one they will never achieve their max capacity potential. Any constant usage at levels below max will shorten their useful life.
Lithium chemistry has a finite shelf life anyway and they are dieing from the moment they are manufactured. They are designed to be used in this way and you won't see max levels for may be a couple of weeks after first charge.

Actually, yes, you're right, I wasn't thinking. I meant to say the cut-off mechanism in the device itself in conjunction with the electronics inside the battery which report the voltage to the device should together protect the battery from serious damage.
Otherwise, what's the point? Everyone will accidentally let their device run down to automatic switch-off occasionally; it happens. And it shouldn't trash the battery if promptly recharged. As a benefit, the meter will be more accurate next time round.

The only downside of charging more frequently than necessary is more heat, which Lithium cells don't like, it's another life shortener. Other than that, I agree, there's no "memory effect", so it shouldn't matter what your charging routine is, although some sources say Lithium cells last best if not kept continually fully charged, but rather around 50-60%.
Lithium chemistry has a finite shelf life anyway and they are dieing from the moment they are manufactured.

Agreed. And not widely known, otherwise people wouldn't buy "bargains" which have been in stock or a shop window for 2 years.
Well, to make this clear. I did this battery format (or calibration) twice. When the phone was brand new. Just to make sure, I have the full capacity. I guess, that my problem is the phone power compsumtion. When its suspended and home screen (battery plus) is shown, and spbsheel running on background, the power drain is 83 mA/h. This is shown immediately when power button is pressed and display lit up. So the display powering is not counted in this 83mA/h.
I guess this is too much for Topaz ESSentiaL V2.F, isnt it?
WIFI, gps, and bluetooth was off, only phone on.
I think you need to do some careful tests to find out whether anything is faulty. Such as checking how much the battery level decreases overnight, first with everything including the phone module off ("flight mode"), the next with just the phone module enabled. With everything off, you should only lose 2-3% max overnight. If it's more than this, either some app you installed is repeatedly "waking it" from suspend without your knowledge, or the device or battery is faulty.
Even with the phone radio left on overnight, you shouldn't lose a lot more. I leave phone and bluetooth enabled, and only lose 6-7%.

Thank you for good point, I will turn the phone off over night (other modules are off always unless I need them). And will see, how much it will drop.
Isnt the "flight mode" the same as simply all radios OFF?
I dont use GPRS (CDMA, HSPDA, WIFI, GPS ...)
Well, the night pasts and I am very very confused. I left the PDA at 21:15 with all radios OFF and 12% of battery level. Now its morning 07:15, so that is 10 hours of iddle...and the battery level is 12% !!! Did not loose a bit. So does it mean, that the phone (ON during the day) drains so rapidly battery?
As I read the forum I tought, I have the best radio so far for Europe (Czech Republic).
My Radio: 4.49.25.17
Any suggestion?

My Android OS drain culprit -

Edit: just so u know that that the process irq/325-k3g is causing the android os issue. Once again this process is only visible in the free app osmonitor. I let it run wild for couple of hours and it drained my battery excessively and also made android os go up to 50% battery usage. So it seems the culprit for the android os drain is process irq/325-k3g.
The process is just showing consumption when the drain happens and NOT all the time. So if u see your battery dropping quickly have a look to see if the process is consuming CPU . /Edit
Right, so ive observed lately that when my battery starts dropping % quickly that a process called irq/k325-k3g is consuming a lot of CPU.
This is only visible with the app osmonitor under process.
This randomly happens and seems to be triggered by the stock browser.
If the process kicks up it won't stop on its own, I can't stop that process in osmonitor and thus causing excessive battery drain cause it continousely uses cpu. The only way to stop this process is by killing internet (browser.apk).
I had the same problem on all roms I've tried so maybe someone else suffering from this find this helpful.
This doesn't solve the root of the problem but atleast its a temp fix.
Any feedback appreciated.

i feel your pain , i am getting almost 10% drain per hour
So nobody experiencing battery drain caused by the above process?
Sent from my GT-I9100 using Tapatalk
The problem is that everyone is quite about this problem. Battery life is rubbish and no one is putting forward any advice or detailed fix for the problem.
So back to your solution mate, does this process work when you use opera mini? I never use the stock browser.
Kind regards,

A coworker showed me his SGS2 today : uptime 2days 23h and still 39% battery remaining..
config :
1) No airplane mode
2) No wifi at all
3) No gapps autosync
4) No task killer
5) some phone calls (20 minutes), a few sms and browsing. A little gaming too..
I have the same config : but poweroff after 1d and 6 hours...
irritating
I've had 2 different units and found the battery life to be awesome on each one. I'm wondering whether users previous handsets are coming in to play i.e. are they coming from Blackberrys or old Nokias?
Quietness on a certain issue tends to point to most people not suffering from it.
Regards.

why he did not got a usual phone .
The problem is the huge battery drain in idle mode , i had a galaxy s before the drain was 1.5% per hours now i am getting 8-10% per hour
a non sense
To be honest I thought my battery life on my Nokia N900 was crappy, max 2 days, usually though 1 1/2 days but coming on to my first Android, battery lasts me less than 17 hours on average lol
I was surprised, I was expecting more actually considering it is a more mature OS than Maemo, might have better battery management. Guess I was wrong haha.
That said I keep my phone charged to my PC when ever I am at work so it doesnt really bother me much.
Ever thought that maybe you've all got an awesome phone, maybe just playing with it quite a lot more than you would have any other phone.
I know i am, but when i had a day off playing it lasted 2days with 37% left.

Sorry guys, this thread is about some rogue system process that causes battery drain, possible triggered by the browser, very specific issue.
so please lets not turn this into a typical "my battery is bad/good" thread.

All I can say is a factory reset doubled my battery life and fixed my problems
An explantion by a google engineer for the battery drain issue:
Comment 297 by [email protected], Apr 7, 2011
A problem has been identified in the driver for the wifi device on the Nexus One (bcm4329). The problem can cause the phone to repeatedly enter its suspend state and immediately wake up, resulting in a severe degradation of battery life. The problem has only been observed on Nexus One running the Gingerbread updates to the wifi driver and device firmware, although the driver is used in other phones as well. A fix is in the works, but I don't have information on a release at this time.
Turning off the wifi device, or modifying the wifi sleep policy to never sleep, may avoid the problem in the meantime.

Good luck..... I'll drop in when the thread has hit 10 pages of random battery chat and try and find a mention of the relevant process!
Seriously though, I'll keep an eye on the process and see if I notice what you say in the OP.
Regards.
Here is a more exhaustive explanation:
Comment 261 by [email protected], Apr 20, 2011
@nsbu: The message about "'uart_clk' not off" looks alarming but is actually harmless -- this clock doesn't prevent the SoC from suspending, and this message always appears at suspend time in Android kernels running on Qualcomm MSM chipsets. (If other clocks were listed here then those could represent a problem.)
Similar to a previous report on a T-Mobile myTouch 4G discussed here, the data logged on wakeup reasons needs to be interpreted by the OEM that has the hardware specs for the phone and the Qualcomm radio firmware source that generates some of that info. HTC is the OEM for that phone; their support site is http://www.htc.com/us/support . Or try the T-Mobile support site at http://support.t-mobile.com/viewAllProducts.html , they seem to sell this device under their own brand.
In case anyone's confused, it's recognized that some phones do have battery life problems that stem from: (a) not properly suspending to low-power states and, (b) continually attempting to suspend and resume, burning CPU in the suspend thread. The causes tend to be due to devices continually generating interrupts (that might not be properly handled by device drivers and hence continue to be generated), or drivers rejecting suspend for conditions that should be short-lived but instead persist for long time periods. In many cases the drivers involved are written by OEMs and Google does not have any knowledge of the drivers or devices causing the problem -- the folks who made the phone need to take a look.
Problems with the Google Nexus One described in another issue referenced in previous comments fall in the same category, and in that case we have the hardware and the design info needed to diagnose the problem (wifi driver interrupt handling problem), and a fix is on the way.

Well, for me the battery is good. I don't use phone much for gaming and surfing but there are a lot of calls, maybe 3-4 hrs of call time or more. Also I keep quitting running services like social hub, voice command etc.

Voice calls isn't a way to check your battery life. As soon as you hold the phone near your ear, screen turns off. For proper checking, you have to surf internet via Wi-Fi/3G, play Games, watch Movies etc..Just keep the screen on. I think if you even talk 6/7 hours per day (and do nothing else) then the GS II will last for more than 2 days, surely. Voice calls can't be a way to check battery, for any phone.

Yes I know voice isn't a way to check battery. But like I said its good for me. I previously had iPhone 3G which I used like I use my GS2 and it gave me hardly 5-6 hrs usage of battery. So happy with GS2. I'll test my battery life by playing games and surfing and all that and I'll let you know the result.

That would be kind of you.
For me, on Wi-Fi, at Auto Brightness in stock browser, with SetCPU set in Ondemand mode, battery drains at a rate of 18-20% per hour (I don't let the screen off). Lets see if yours are better or not
i'm very happy with my battery performance.

Unusually high battery drain in deep sleep with just GSM on

After freezing some twenty applications with Titanium Backup, I finally got this phone to properly enter deep sleep. Here is a quick demo:
(I'm sorry for the images' quality, it's ScreenFilter in effect)
{

"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

I only have the HD2 to compare, which, either with WM6.5 or Android (CM7 flavour), reported, with its builtin battery chip, 4mA of drain to stay connected to the GSM carrier.
Surely enough, since silly Samsung doesn't like to use decent battery controller chips in their 800USD flagship phones, which any HTC device has, the estimates from Battery Monitor Widget, as, per se, estimates, so I cannot really say the numbers are exact, nor I have a definite idea of how they are calculated.
But still:
And, more in detail:
(yes, I know I could've copy/pasted the txt log in here, but surely a screenshot is nicer to look at )
I shamelessly forgot to take a shot of the Android stock battery usage screen, to which I actually look quite seldom; to my defense though, all these screenshots have been taken one after the other, so refer to the same moment; I had the phone charged, then unplugged it and reset the timer on CPUspy, WiFi stayed on just for a while, then disabled; no GPS, no BT, "GSM Only" selected in mobile networks.
I have found a weird behaviour: the drain is 2mA (according to BMW estimates) for quite a while right after the battery is charged. When you happen to actually "use" the phone for a while, the deep sleep drain instead, as estimated, skyrockets up to 30-40mA, to slowly go down again, but never quite low as the drain on my HD2. In the attached screenshots, it stabilized to 17mA, which is still 4 times the comparison of 4mA for the HTC.
A silly deduction: this must not depend on the kernel nor the ROM, since the deep sleep state has the CPU totally inactive, but is there a "radio firmware" that changes this behaviour?
Most importantly, what are your deep sleep mA readings with Battery Monitor Widget?
On a side note, I briefly connected the Note to my PC via USB to copy over the screencaps, and now after a short USB charge, BMW is reporting 2mA again...
How about sharing what apps you froze?
Without giving a full list (that would be dispersive and especially I would have to write it by hand which is annoying ) I suppose you can start with the obvious, all samsung apps, especially the updaters, and those that have a huge internet background activity (freezing IM+ in my case helped, but that sucks if you use chats a lot... I dont), then pass onto the tricky ones you would never suspect, like Network Location and Google Maps/Google Streets
If it doesn't solve your problem let me know, I will go and compile a list, but keep in mind that at first I just uninstalled system apps from Titanium, so the frozen list will be uncomplete of those uninstalled apps.
Quick update: for just this night, I tried leaving the phone on in airplane mode: 8mA drain just to be in connection-less standby!! That's ridiculous, it drains double with no connection active whatsoever, than what the HD2 needs to keep the GSM network connected. Re-enabled the GSM this morning, went to 17mA, so I suppose the 2mA that I see right after charging are, as suspected, just an artifact of BMW estimates.
This resulted in 4% over 7 hours (4% of a 2500mAh battery) in airplane mode, HD2 under WM drained 3-4% over 8 hours nights with GSM on (on a 1230mAh battery).
This phone does have a ****ty energy management.

I left the note (stock, not rooted) on for about 9 hours this night with 4% battery. This morning it had 1% left. To force it to shut down i opened wifi, read my mails and watched 2 songs on youtube.
All i did for the night was to set it to GSM only mode, close all active apps and clear the RAM from the build in task manager. I haven't experienced samsung apps keeping the phone awake yet.
Hi Bassarnis, and thank you for your report
Your experience may lead to believe it actually drained "just" 3% overnight, yet, with CM7 on my HD2 I had the strangest things happen especially when battery was (reportedly) almost drained.
Android (with its silly battery management) would tell me the phone was at 5%, and I just went on using it until 1%; even doing the nastiest stuff to drain that last 1% it took a notable while before the phone shutted down.
Turns out the battery wasn't really drained, but the phone told me it was, because of the useless, illogic, un-asked-for use of "battery statistics", combined with the fact that this OS thinks a battery is depleted when the dV is still 3600mV-ish (LiIon can stand to be discharged up to 3V with no damage).
In this case your leftover 1% could very well mean, in reality, a 6-7% ;D
I would love to know how much %age your phone drains overnight with GSM, starting from a good charge

I charge my phone while its off. I know the effect you are describing. It could well mean that the battery wasn't properly charged the first few times, leading to the last 1% = 5%.
I don't guarantee that my results are accurate, since bought the Note 48 hours ago. When i bought it, i used it until the battery depleted and then charged it to full while it was off. Now its the 3rd time i charge it and i believe the percentages will be more accurate from now on.
Will try tonight and let you know tommorow
Thank you for your interest in this matter

Here are the results:
As soon as the indicator showed 5% battery left at around 23:00, closed all apps via the build in task manager and cleared the ram. (GPS/WI-FI/Auto-synch/Data = off, network set to GSM only)
Now at 7:00 there is 3% left after 8 hours of sleep time. That is 2% more than the last time. Currently the phone is on it's 4th charge circle using the method posted above (letting the phone shut down by itself, then charging it while off till 100%). I 'll probably do one more circle and then start charging the phone whenever.
after reading this thread was a bit worried so did a test last night,after a full charge from 1 am until 9am with only gsm on it consumed just 1%.
so no complains here on my wife's galaxy tab 10.1 she had the same draining problem,but after disabling the GPS it was solved.
Apparently there is something terribly wrong with either my phone OR my software... are you both on stock ROMs? And which version of firmware?
Thank you!
Ive been getting more than 1% drop over 8hours since my SGS2 days.. so this is nothing new to me.. only my SGS1 could drop 1% every 9.5hrs of idle.

Stock 2.3.6 not rooted here. I believe that battery monitor widget you use keeps your phone awake. Did you check your wake times?
You know, I've thought about it very much, regarding BMW and possible interferences with wakelocks, since it has to update stats every 10 minutes after all... but it's still once in 10 minutes so I don't see how it can weight for so much.
Also, I had battery monitor widget since the phone was still on KJ4 and unrooted, fresh out of the box, without a SIM inside, and with logging every 5 minutes instead of 10.
You can compare the graphs of the battery drain (one day is equivalent to two columns):
Before pimping up the phone, stock KJ4:
After, with ExtraLite rom and Abyss Kernel:
I obviously studied reports from betterbatterystats and nothing big seems to come out from there, apart from three causes for wakelocks that I cannot really pinpoint to anything specific: ActivityManager-Launch and AlarmManager, time-wise, and ActivityManager-Sleep, count-wise.
Out of curiosity, I disabled BWM, to see if anything changes.
But I reckon this is some kind of Schrodinger's cat situation, because I can't know the battery current drain of the phone when BWM is not active, if I don't use BWM
My last resort is to restore the nandroid of KJ4 freshly cf-rooted and see from there
Thank you all again for the interest, and
@EarlZ
1% down overnight is scary, positively speaking. I was content with 3-4% with the HD2 and WM6.5.
I was on the 1% mark overnight (less actually) only with my iPaq 214 But then again, that was not a phone, and its standby was a proper standby. And it had a battery almost like the note's.

Battery troubleshooting (ROM inspecific)

This thread is to discus extremely poor battery life on the Nexus S. When we say extremely poor, we mean averaging <24 hours per charge at idle.
After much research I think it's safe to say that some of us are experiencing extremely poor or contrarily, extremely good battery life and no one seems to have an explanation. I'm hoping this thread will find the answer.
The issue:
Many NS users are experiencing extremely poor battery life regardless of:
Rom installed
Apps installed
Installation method
Battery used
Charging method/battery training
Phone usage
Power configuration/tweaks
When we say "extremely poor" we mean <24 hours at idle, but many users are getting less than 8h/C at idle.
I personally have tested this against several ROMS both GB and ICS. We all see slightly better battery performance with GB ROMS, but never greater than 24h/charge.
My ROM history:
Tested the following ROMS for 4 days each, following the same installation procedure each time.
CM7 (nightly/stable) - ~15h/[email protected]
CM9 - ~13h/[email protected]
CyberGR .v4.5 - ~11h/[email protected]
CyberGR .v5.0 - ~11h/[email protected]
Installation method:
Wipe battery stats
Wipe data/factory reset and wipe cache partition
Flash Dalvik-wiper.zip and wipe Dalvik Cache
Wipe data/factory reset and wipe cache partition again
Format /system/data/cache/boot/sdcard
Flash ROM
Flash Gapps if applicable (CyberGR comes with Gapps installed)
I was running an AUCKF1 Radio for all tests. I did try a few other radio's but did not see any noticeable increase in battery life *edit-flashed XXXKB3 and may have increased my idle time by 6x? still testing*
I've also never personally seen an NS get >24h/C, and I've deployed >40 of them to customers. I've only ever heard of >24h/C here on the forums where it seems quite common.
I've seen reports of users flashing the OTA automatically or manually, and some experience <8h/[email protected] while others see >3d/[email protected] I've also tested the OTA and never saw better than 13h/[email protected]
So, we're trying to find the common denominator between those with good battery performance vs. those with poor performance.
Suspects:
Android OS is almost always reported to be active/awake for at least 50% of the time, even at idle on a brand new clean install. It is always the highest consumer of battery, always keeps the CPU awake.
I propose the following test:
Regardless of your setup, if you are experiencing >2d/[email protected] or with use, please post the following:
Phone model (ie: i9020a, i9020t...)
ROM
Radio version
Installation method
Screenshot of your battery monitor from a full charge over a minimum of 10 hours.
Screenshot of your battery use by application/service (we notice that Android OS seems to be the culprit in most cases of poor performance)
For those getting <1d/[email protected], please do the following and then post the same as above:
Note: This should be done overnight.
Follow the above flash instructions and flash whatever ROM you please.
Reboot to recovery and wipe your battery stats.
Power off your handset and give it a full charge while powered off.
On first reboot, sign into a single Google account but do not restore your apps/backups and disable Google sync.
Do not install any additional applications.
Enable wifi/bt/gps/data/sync and associate to a wireless network
Do not modify any power settings.
Leave your handset to idle overnight for at least 8 hours without touching anything.
In the morning, take a screenshot of your battery use as well as battery use by application/service.
Post Phone model, ROM, Radio version, Carrier, and Screenshots.
I recognize that there is some argument about how fast your battery will re-train itself after wiping battery stats. In my experience the training seems to be optimal after 1 full charge to full discharge cycle, but ultimately I've never seen further training result in >24h/C. Someone please let me know if there's a more accurate way to test this? Maybe we shouldn't be wiping battery stats at all?
I'll get us started.
Sorry, didn't get screenshots after 8 hours because my battery wouldn't last that long.
Phone model: Samsung i9020a
ROM: CyberGR .v5
Radio: AUCKF1
Carrier: Rogers
Wifi associated, BT on, Data on, Sync on, 3G connected, added one Google account but did not restore settings and disabled account sync.

With light to moderate use, I get 6-10h/C
Hey Ben i just did what you did in the other thread. full charge everything on kill all unneeded services.
I'll admit that i forgot to kill extra services and it plummeted my battery to 92% in about 45min. I had an "oh ****" moment and went and killed the random apps.
Im at 2 hours extra now and lost 3% only, everything still on.
So with that info i'll mention this for me would be considered heavy usage. I'll never have everything on constantly. When I was posting up my results of light usage and getting 3 days - note that i had everything firewalled while on 3G except for my emails and messaging and took a few calls only. everything else was off.
I'm gonna guess that with it all on and actually using the phone i'll hit at most 10 hours, probably not even that.
So that basically puts us about even. I'm curious if you do my light tests...will you be seeing 3 days also ? If yes then we can rule out models basically.
Flashed XXXKB3, factory reset (according to OP instructions), flashed CyberGR .v5 again, signed into one Google account, disabled Google sync+backup, enabled and connected to wifi, bt/gps/everything on, then left my phone overnight. Results.
Looks ****in' Gooood. 1.2%/[email protected] draw.
But then, opened my screen once, played some tunes through BT to my truck, drove around for 13 minutes, went back in the house and left the phone idling again and look at the drop! It's continued to draw like this all day now, just idling. I've done NOTHING but play 13 minutes of music and then back to idle.
What's DOES IT MEAN??!!
So I rebooted my phone and let it idle again without touching anything, and still seeing the wicked battery draw. I dunno wtf to think here, and I can't get the draw back down to 1%/[email protected]
*edit* For the sake of 100% transparency, while the phone was idling at 1%/h overnight, I was far enough away from the wifi AP i'd associtated to, that it MAY have lost signal and given up, so perhaps the wifi hardware finally went to sleep. Does anyone know if wpa_supplicant (or whatever controls wifi in Android) runs is represented by AndroidOS?

Oh. Dur...
I think that may be it. Wifi was probably dis-associated overnight. You can see at the very beginning of the battery recording, there's a sharp dip in charge for about 15 minutes, which corresponds directly to Wifi association, then the draw goes nearly flat (1%/h) for 10.5 hours and the Wifi is not associated.
Testing now... Leaving Wifi on, but dis-associated. See if that nice flat line comes back.

This is a normal night of going out, connecting with friends, a bit of music before. A weekend for when it is most important, these are the results. I forgot to photo the android os but it said it was awake, cpu for 4 hrs.
Regarding the Android OS being highest battery consumer, it might be false alarm:

Although still, that hasn't explained the high drain (<10h/day) you're experiencing.
In your first set of screencaps (the 2h30m one) it seems obvious that the culprit is Mediaserver and Google+? One of the most annoying things about ICS that I found is that after flashing ROMs or kernels, Google-Photos have a tendency to enable sync behind our backs. Someone in my local forum discovered when he logged in G+ in his PC that the pictures in his Nexus S had suddenly shown up in the G+ account even though he never uploaded them there. After he disabled that sync, his battery life improved. As a result, I've grown OCD about checking my sync settings every once in a while. The Google-Photos option doesn't always show right away when we set up a new Google account.

Phone model and radio?
I'm back to 1%/[email protected] with everything but wifi enabled.
All sync settings enabled with no sync delay.
G+/data/gallery sync all enabled for 3 accounts. Receiving about 30 emails in 14.5 hours overnight. This should work out to 111h/[email protected]
The question here for me is that I thought Wifi would use less power than 3G given it's such lower range. I thought that when Wifi was associated that your 3G would automatically disconnect, thus using less power when associated to a Wifi AP than when connected to 3G.
Am I mistaken in this? Is this not the desired operation?
*edit* It may be looking like my draw increased by about 8x as soon as I opened the screen for the first time this morning, and hasn't dropped back down to the 1%/h. Right now it seems to be at about 10%/h again, though I'll report back on this later today.

D720 ns4g and latest radio - D720SPRKE1 or whatever it's called.
I'm getting the same...
power drain increases for dunno whatever reason...
right after a reboot it goes ok if I do not touch it... as soon (or five minutes later) as I start playing with it the power drain increases a lot and android OS takes over any other service...
generally to test I wipe the battery stats before booting from recovery...
maybe we should check in logcat what trigger the high android OS usage?

I've checked logcat/dmesg and haven't seen anything super suspect (to my somewhat untrained Android eyes). I have done a tonne of power management scripting/troubleshooting in laptops and other mobile devices but this is really my first serious foray into Android PM, so I may be missing something.

As I said, stock settings from CyberGR .v5. Signed in to all three Google accounts and left sync enabled. Turned off Wifi but left everything else enabled.
Drove around (phone paired to my truck for music) for a few hours today, light/moderate use, and I'm currently sitting at 69% battery remaining, coming up on 24 hours on battery. Realistically, this is probably a little lighter use than normal for me, plus I usually plug in when I'm in the Jeep as I'm running not only music over BT to my Jeep, but also streaming OBDii data from my ECU to Torque (and my screen is usually on full time while driving as I like to keep track of my mileage (troubleshooting fuel efficiency as well ).
So all said, stock settings with CyberGr, Radio XXXKB3, Wifi off, everything else on, and I should easily get 2 full days of light use.
Now that said, I'm still waiting for someone getting 3-5 days to chime in. I still feel something isn't quite right.
Wow. Practically the same as myself but my battery is now around 6-7 hrs before I need a charge. I will have to buy a new battery and see if that is the culprit. Over even just flash CM9 instead, who knows..

I doubt it's a bad battery. You're seeing the same life I was before I flashed the XXXKB3 radio and re-installed the ROM properly. Follow the installation instructions from the OP and see if that solves your problem.
After looking at an earlier shot here I notice my android os stays on most of the time hence my bad battery. How do I get it to sleep?

So does mine, but it is not an accurate reflection of battery drain, per android engineer Dianne Hackborn. Look at the Android OS percentage in my screen shots - it doesn't matter.
For those with excessive battery drain: install Battery Monitor Widget and Better Battery Stats from the market. Those two apps should provide all the data you need to troubleshoot poor performance.
Also, check your signal strength. Weak reception will drain your battery in a hurry.
