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.

I flashed with Topaz ESSentiaL V2.F. But have no GPS
Tomtom7 nor Visual GPS can not find GPS. Set it to COM4, baud 57000. Still nothing

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%.

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?

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

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?

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?

U can try flashing one of the more current cooked roms.
yep i flashing all the coocked roms found this huge forum and....same problem
Not sure if im the only one experiencing this issue but i think that the battery dies entirely too quickly!!! Being that i have a launch day batch i'm not sure that everyone is experiencing this issue! IT seems like the LESS i use the phone the faster it dies, i know totally contradictory but thats what it seems like any ideas, known tweeks. Let me know
There are a few ways to fix this. Most can be found through a quick search. Trying a task killer, adjusting settings and rooting/flashing a new ROM are some ways to fix that issue.

Nope haven't had this issue, had mine since launch. If its really an issue for you, buy a new battery and if that doesnt work there are other fixes around this forum that you can try
turn off background data
adjust settings so that things aren't syncing as often
turn backlight from 'auto brightness' to a low setting
turn wifi sleep setting to 'never'
turn off bluetooth, location settings also
i had mine off the charger for 16 hours still had over 80%

well, tbh, most of it was in standby. short phone call, some texts, that's about it. it wasn't as if i was putting the phone through the ringer
See if there is a difference between weekdays and weekends.
I do have the same short battery life and my battery will die around 6pm on weekdays if I don't charge it during the day.
However, my evo was able to last all day this last weekend.
The only reason I can think of is that I have weak reception where I work and the phone is probably using full power to keep that connection. Hence the massive battery drain.
If your signal is bad, your battery will die very fast. I work in a giant metal box of a store with a constant 1 bar. My battery drains like crazy. If I disable mobile network it increases ALOT.
Make sure you have the updated radio and there are plenty of battery fixing threads. Custom rom will help a lot as will removing the bloat.
I can cosign on this issue. Last night I had the phone on the charger. I unplugged it because it was fully charged and I don't like keeping my things plugged in all night. I wake up this morning and reach for my phone and it's practially like 25% battery life. It was on standby and I didn't set up Friendstream, Auto Syning, etc. I have everything on my phone set to manual.
interesting thing i just noticed on my battery; i just fully charged to 100% (using battery indicator); i left it on the charge for another 5-10 minutes, then unplugged it
literally couple of minutes later, battery shows 95%; not sure why it's doing that since i don't have any apps running in the background and my signal is fine; after it got to 95%, it seems to start draining normally
this is the 1st time i noticed it; the previous time, it drained normally (100 > 99 > 98 >etc.)
You know why its hard to nail this down?
Its because people say
"i took my phone off the charger and in 4 hours of stand by its now at x%"and that's pretty much it.
Some facts:
Without knowing your db we don't know what kind of signal you have.
All task managers are NOT created equally. Just because the free one you got says there isn't anything running doesn't mean that its not still on in the background. If you are running sub 175mb in free ram then you have stuff running that doesn't need to be. Find a different task manager
If you root the device and download one if the many custom ROMS. Remove all the stuff you do not use. Your baster life will go through the rood. Gsd and other crap that does nothing are huge battery hogs.
If you can't be bothered into doing the above then you aren't going to find any answers. Either but an extra charger or return it. You can fix it but its going to taker you doing something.

It was on standby and I didn't set up Friendstream, Auto Syning, etc. I have everything on my phone set to manual.

See this is what I'm Talking about, I'll take my phone of the charger in the morning and by the time i get to work 15 minutes later! My phone is like at 70% Without me even touching it, Waking it up. Recieving texts or anything. The roads that lead to my work are well serviced areas of sprint reception so i know my phone isn't looking for signal. This is a major drag!

You know why its hard to nail this down?
Its because people say
"i took my phone off the charger and in 4 hours of stand by its now at x%"and that's pretty much it.
Some facts:
Without knowing your db we don't know what kind of signal you have.

My DB is always low(closer to -0 the better) so i know that is not the issue.... next!
With good db that isn't normal drain. Return it for a new one.

Free Swap Here i come
Selling Sprint phones at Radio Shack doesn't make you a tech... I worked at a company called WDS Global a couple years ago. THEY are techs. As a matter of fact, WDS Global handled all the tech support for the EVO on launch day. They even had a rep in my local store.
As i am a tech for sprint, i know about all this and i have all those settings off, wifi, mobile network, Brightness down, bluetooth is always off. And to no avail!!! I must have a bad battery! Seems like store demo i use to show customers last longer, HAHA. Even though if i still see an issue i will just swap a battery out of new one( PERK OF THE JOB)

Use damagecontrol the ROM in the evo development section of this forum it increases battery life because the dev tweaked internal system it worked wonders for me give that a shot.
After freezing some twenty applications with Titanium Backup, I finally got this phone to properly enter deep sleep. Here is a quick demo:

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.
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.

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:
http://forum.xda-developers.com/showthread.php?t=1456265
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.

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.

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.
Hello,
Introduction
You can see my problem here:
http://forum.xda-developers.com/showpost.php?p=50558312&postcount=152
I was only getting about 3h 45m @3%
Now you can see that I got 3h 47m @51% (Very Happy)

That's nearly twice my old results
Now, I'll talk about what I did...
It's all about calibrating my battery
I knew that my battery needs to be calibrated when I had these symptoms:
1- I was able to get a full charge in about 2h 9m (Now it takes up about 3h 30m)
2- I could use my tablet for about 2 hours while I was stuck at 1% !! (see the post mentioned in the intro)
3- When I play any game while I'm below 50% of battery, it simply jump by big values, sometimes it reaches 15% suddenly and I get the recharge message
4- My tablet was new, and I couldn't get more than 4 hours while others could get about 7-9 hours!!
What I did:
1- Fully discharged my battery, I stayed for about 2 hours playing movies, the tablet turned off, then I could run it again and still see 1%... did it again until one time it turned off immediately after running it (I saw that battery was 0%, it was the first time to see that)
2- Did a fully continuous charge and didn't unplug it
3- Installed Battery Calibration app:
https://play.google.com/store/apps/details?id=com.nema.batterycalibration
4- Unplugged AC, then clicked "Battery Calibration"
5- Fully discharged the battery (didn't use any draining apps, just normal use)
It was about the same result
6- I disabled all of the battery saver apps (even Greenify) except Bataria (It really makes difference for me)
https://play.google.com/store/apps/details?id=com.jappka.bataria
I also installed Lux Auto Brightness
https://play.google.com/store/apps/details?id=com.vito.lux
Finally I've installed 2x Battery later, I'll report the results back soon:
https://play.google.com/store/apps/details?id=com.a0soft.gphone.aDataOnOff
6- After 2 fully charging and discharging, my battery life was about the double
And that was after the first cycle:
It improved on the next one and I got 7h
Good luck everyone
What is the Virsion of your device ?
is it wifi only (n 5110) Or 3G wifi ( n 5100).

Hello,
Introduction
You can see my problem here:
http://forum.xda-developers.com/showpost.php?p=50558312&postcount=152
I was only getting about 3h 45m @3%
Now you can see that I got 3h 47m @51% (Very Happy)
Screenshots:
Before:
After:
When I was @9% , my screen time was 7h
Screenshots:
That's nearly twice my old results
Now, I'll talk about what I did...
It's all about calibrating my battery
I knew that my battery needs to be calibrated when I had these symptoms:
1- I was able to get a full charge in about 2h 9m (Now it takes up about 3h 30m)
2- I could use my tablet for about 2 hours while I was stuck at 1% !! (see the post mentioned in the intro)
3- When I play any game while I'm below 50% of battery, it simply jump by big values, sometimes it reaches 15% suddenly and I get the recharge message
4- My tablet was new, and I couldn't get more than 4 hours while others could get about 7-9 hours!!
What I did:
1- Fully discharged my battery, I stayed for about 2 hours playing movies, the tablet turned off, then I could run it again and still see 1%... did it again until one time it turned off immediately after running it (I saw that battery was 0%, it was the first time to see that)
2- Did a fully continuous charge and didn't unplug it
3- Installed Battery Calibration app:
https://play.google.com/store/apps/details?id=com.nema.batterycalibration
4- Unplugged AC, then clicked "Battery Calibration"
5- Fully discharged the battery (didn't use any draining apps, just normal use)
It was about the same result
6- I disabled all of the battery saver apps (even Greenify) except Bataria (It really makes difference for me)
https://play.google.com/store/apps/details?id=com.jappka.bataria
I also installed Lux Auto Brightness
https://play.google.com/store/apps/details?id=com.vito.lux
Finally I've installed 2x Battery later, I'll report the results back soon:
https://play.google.com/store/apps/details?id=com.a0soft.gphone.aDataOnOff
6- After 2 fully charging and discharging, my battery life was about the double
And that was after the first cycle:
It improved on the next one and I got 7h
Good luck everyone

That's Great :good:
Thanks for sharing, but I think the info is partially inaccurate.
Lithium-ion batteries do need calibration (http://batteryuniversity.com/learn/article/battery_calibration), and thank you for pointing out that it's convenient to do it after flashing a new ROM, I didn't know that, so thanks again
The app you linked has the following in its description:
"Calibration needs to be done after flashing a new ROM, but you can calibrate any time you think your battery is miscalibrated. This program does it by removing the batterystats.bin system file."
There's evidence on XDA stating that the batterystats.bin has nothing to do with battery calibration, and the source of such evidence comes from Dianne Hackborn, Android developer for Google. The thread I linked is not the only one reporting that.
So it seems to me that yes, you do need recalibration from time to time (I'm going to do it soon), but no, you don't need to do all that, in fact it would be enough to fully discharge and recharge the device.

Thanks for the information ...
hmmmmmmmmmm, I don't know what to say,
I just shared what I done accompanied with my results... every single thing that I did
At least that worked for me and I see that my battery gets better now (I'm able to play games without seeing my battery drain insanely)

I'm not questioning the fact that it worked, but the number of required steps. It doesn't look (to me) like you're doing something wrong, but it rather looks (to me) like you're doing something unnecessary. However that's just my opinion, the final proof would only be obtained by trying each combination of steps on multiple devices and ain't nobody got time for that.

What I know about the batterystats.bin is that it stores data about your battery consumption, right?
When I was getting 4h when my battery hits 5%, I could get another 2 hours stuck at 1% (as mentioned)
Don't you think that may helped to store more accurate data about what the battery is capable of?
Or maybe when I removed the stats file and drained my battery normally for the first time without heavy usage also helped giving better data?
I'm just trying to figure it out somehow

I think what helped you was battery recalibration, which was obtained by draining it completely and then fully recharging.
"Batterystats.bin" stores the data that's shown in the "Battery" section of the settings and gets wiped every time charge gets to 100%, so an app that deletes might not be bad, but rather pointless. The data collected in batterystats.bin is different from the information about the charge of the battery, which is the one that was affecting you.

HA this is funny... Now that I read this. Unfortunately I do not have a link, but you can google for it.
Google states that resetting or calibrating the battery performance on Android does not work any better than leaving it alone.
Google: Battery Status Resetting Google. I am sure you will find it.
It is possible that your media was the issue. All you had to do is use Battery in the system to verify what activities were draining before and after.
I have a thorough thread on battery drain in the Q&A section. Take note, I did not recommend doing any battery optimization or resetting.
If any thing allowing the battery to drain down to 20% before charging to 100% should be good enough to allow the system to properly adjust for charge and discharge time.

What part do you find find in particular? Anyway, I read that every once in a while (once in more than 3 months) Li-ion batteries should be recalibrated, whether they power an Android device or a toaster. Meanwhile, it is wrong for the battery to discharge it completely every single time: it is better to do 20% wide cycles.
My main source is http://batteryuniversity.com/, but I found the same things over and over again in multiple places. I'm aware it might as well mean nothing, but one's got to believe in something

Ok, what was funny is everyone wants to think the battery is so problematic. Have older devices with Li Ion batteries, and the only issue I have is how the device may lock the usb until shutdown. I wait a minute after full power down before connecting a USB charge cable. As for charging when the device is on, I leave the device connected to the charger when powering on.
Google developed Android and its features to monitor battery charge / discharge state. I will look for you the article from Google about such things as using apps to tune battery or clearing the battery log.
Here is some reading for you on the the xda site... http://forum.xda-developers.com/showthread.php?t=2170039

That says that wiping battery stats (=deleting batterystats.bin) does not affect the battery life and that it doesn't help recalibrating the battery, because in fact the file batterystats.bin gets automatically deleted every time the charge percentage gets near 100% (it does not even need to reach it), and it only has to do with the battery usage stats in the settings app. I repeated that a number of times already.
In other words: that thread says that wiping battery stats to get more battery life is a myth, which is the same thing that I said earlier, quoting the same Google engineer. Recalibration of any Li-ion battery is a whole other thing.

Appearently some Note 8's batteries are problematic: it's not normal for it to last hours at 2%.

I believe (I'm not sure, I didn't spend days studying this) that the deepest battery monitoring is up to the battery itself: it's the battery that tells its charge percentage to the device, therefore Google has little to do with it. Recalibrating is something "deeper" than the OS, or at least that's what I understood...
Moreover, "standard" miscalibration normally accounts for some 2-5%, not hours of charge as in the OP's case (I hope it's not "our" case...), so that's why many people had never had any trouble with it.
Anyway, please mind that everything I say comes from superficial reading and experience, I didn't study the matter.
