[Galaxy S III General] mc-paulo:
I thought the same :-)

How unfair life can be ;)
[Galaxy S III General] AndreiLux:
Cell standby seems to be

1) A modem firmware failure for those who actually have bad cell standby battery life. This seems to be caused by not entering low power mode on non active connections or switching to fast/often between the power modes.

2) The batteryprofiles.xml populates the cell idle entry with 33mA as power drain as opposed to 3mA for the S2 which has the older version of same type of hardware modem. This is absolutely retarded as the actual drain is not really that much and being reported much higher than it is.

I personally am running on 2G which is more than enough for chat, email and notifications and switch to 3G whenever I need to manually or am on Wifi. I am still on my first charge since I have gotten the phone, and I'm at around 40 hours lifetime with 4H screen time with 33% battery left. This is with around 20 reboots while flashing and testing my kernel, and playing with the phone. Over-night (8+ hours) I lose about 3%.
[Galaxy S III General] winwiz:
no cell standby issue in CM9 by the way guys
[Galaxy S III General] mc-paulo:
So what you are saying is that it is just a miscalculation? Then the voltage would still show up correct.

Any idea where to find the battery voltage?
[Galaxy S III General] AndreiLux:
Yes that's what I'm saying. The whole battery statistics page in terms of percentages is absolutely useless. Not only are the modem values completely ****ed but the CPU accounting is dead wrong, the values are the same for 1400-900MHz as the Galaxy S2 values for 1200-200, with all the steps below 900MHz being reported as the S2's 200MHz current consumption (55mA). You can absolutely not rely on any of that data for now as it is absolute hogwash.

What does the voltage have anything to do with it? You can't do anything with the voltage value alone, other than maybe estimate battery charge level. Use Battery Monitor Widget if you still want to see statistics.
[Galaxy S III General] mc-paulo:
The Voltage would show if the battery really discharges that fast or if it just is a miscalculation, as you are stating.

My phone is dead after 20hours, no matter how I am using it. The only thing that helps is Airplane mode, but that way a phone is kind off useless.

No wifi, no app and not even the screen are killing my battery. There has to be a culprit and I am guessing, as maby others are, that it's a bug in the radio.
[Galaxy S III General] AndreiLux:
Battery discharge of course it correct, I'm just claiming that the battery statistics and break-down is absolute nonsense. I suspect that it is fast-dormancy, try idling it on 2G/EDGE and see if it's the same.
[Galaxy S III General] mc-paulo:
Ah, now I am getting you.

If it was Fast Dormancy that would explain why two identical setups in two different countries, with different providers are having such different runtimes.

In 2g mode fd is disabled, if I read you right? As I am wifi areas most of the time, 3g is not that important to me. Worth the try.
[Galaxy S III General] AndreiLux:
FD doesn't exist for 2G. So yea, basically disabled.
[Galaxy S III General] whiper:
Added my actual data and i'm surprised. No one has an acceptable power consumption for cell standy. I hope Samsung fixes the problem.
[Galaxy S III General] mc-paulo:
The last hours I was running on 2g only and it didn't do any good.

Experienced nearly the same amount of battery drain than before.

I will switch to another Radio, and will keep an eye on that drain.
[Galaxy S III General] whiper:
At night i have only 2G because in my home where the phone "sleeps" no 3G signal is available. The signal is much more worse, only 1-2 bars, but the battery consumption is even better than with 3G. In 8 hours of Standby only 2-3% battery like it was before with my SGS1. Seems to be only a 3G problem. I checked logcat, but i don't have the fast dormancy problem. I think with 1% per hour with 3G i have a very good performance but in comparison to SGS1 its worse.
[Galaxy S III General] mc-paulo:
What app is able to switch 2g/3g automatically? I've been searching for ages.
[Galaxy S III General] whiper:
I logged 3G network activity with Shark. Even when phone is sleeping there is a communication with google servers every 60 seconds and this is initiated by the phone. Maybe this is why cell standby is so high.

[Galaxy S III General] mc-paulo:
Maybe we should have an eye on the apps and sync-services.

Yesterday I was day over connected to a wifi network, and had 3G activated.

Background Datasync was of, so the google services didn't do anything.

But the drain was still there.

Today I have the same setting but have deleted whatsapp and Skype, but from what I can see after the first 40 Minutes losing 3% without using the phone, I don't think they are the culprits.

So I will keep trying.

[Galaxy S III General] valerio.tosti:
@mc-paulo you just changed the kernel and that's the difference?
[Galaxy S III General] whiper:
The problem seems to be the fast dormany wakelocks.

I took a sample of 780s with BetterBatteryStats.

multipdp = 42s

secril_fd = 45s

Total ~ 9% awake during sample time.

My current values

37:39	deep sleep

43:28 on

02:07	screen on

43:28 * 9% = 41:32

and 41:32 + 2:07 = ~ 43:28 (total on time)

=> multipdp and secril_fd in my case consume 2/3 of my phone's awake time.

If the wakelocks could be reduced this would be an increase in standby time.
[Galaxy S III General] mc-paulo:
Plus I deactivated Flipboard. But the first hour doesn't really tell anything.

And those "percent od usage values" from the Android Battery Screen are not relyable at all.

If anyone wants to add columns to the spreadsheet: Feel free!

Just put tham at the bottom, where I started to gather sysem-settings and apps.

---------- Post added at 02:33 PM ---------- Previous post was at 02:31 PM ----------

I don't see those wakelocks in Better Battery Stats, but still have nearly the same amount of dran.
[Galaxy S III General] whiper:
It's interesting. With 3G (no H or H+) i can't notice any wakelocks related to fast dormancy. I think i'm trying to lock down UMTS to 3G and have a look at my values.

Seems to be random. Tested for 30 mins, also wakelocks. No solution

I don't undererstand why the wakelocks use so much cpu.

I've got only one wakelock per minute, but multipdp and secril_fd use about 9% of cpu. 3-4 seconds per wakelock?

[Galaxy S III General] SlimJ87D:
What was it before? And are your results comparing with your old results with Wifi on or off?
[Galaxy S III General] cmd512:
Trying out DXLEA as well. Was getting some odd drains on cellular, but idle with WIFI was actually pretty good.
[Galaxy S III General] SlimJ87D:
Hey, remember we were wondering if the WiFi issue is due to certain kind of routers. I think it is. I read in another forum for the Note that it is a problem with Dynamic IP addresses via DHCP where the router constantly sends signals to the phone to keep it connected or else it hands off the IP address to another device supposedly.

http://anhttp://androidforums.com/samsung-galaxy-s3/563008-battery-saving-tip-really-works.htmldroidforums.com/samsung-galaxy-s3/563008-battery-saving-tip-really-works.html

I'll explain what I see happening on my phone. Even though I have my wifi policy to turn off all the time, it doesn't when I sleep my phone the majority of the time. The wifi connection stays established and constantly looks like it's sending and receiving data according to the notification bar. Only sometimes it will shut off properly and this is when I get 30 to 40 hours of battery life.

And share your results with that Modem. I want to flash it over on my stock Rom, should work fine right?
[Galaxy S III General] cmd512:
Yep, my WIFI drain issue on my S2 went away completely after I ditched my ****ty Netgear and got the Asus RT-N16 w/ Tomato USB F/W. Didn't have to set a static IP or anything though...

For the modem, loaded it up under Mobile Odin, automatically detected it as a modem. Pressed flash, clicked OK on the "OMG YOU'RE GONNA BLOW UP YOUR PHONE" warning, and done. :)

Been sitting idle at 51% for the last hour or so, looking good so far!
[Galaxy S III General] eitama:
Routers don't prompt phone to keep addresses. DHCP Flow is like this :

Client network device (phone) searches for DHCP Servers

DHCP server present themselves with offers

Client choooses a server and asks for one of the offers

Server Acknoledges and client adopts the IP.

The server and client both know the lease time for that offer

Clients usually renew the lease at 50% time of the lease

The lease is usually for a few days, between 1 to a 7 days.

So, the router will not ask clients to renew or whatever.

WIFI 802.11g/n has other Power management mechanisms that might be screwing the battery.
[Galaxy S III General] SlimJ87D:
Still... the problem is that Wifi is not acting like it's suppose to... and I can't figure it out. If I could, it would help out a lot of other people with bad routers :(
[Galaxy S III General] d4fseeker:
Most problems with routers go away when they are not on their crappy original firmware but e.g. DD-WRT =)

I've picked up 3 cheap (20$) D-Link Dir300 (make sure it's the all-black revision B which in fact is the more expensive Dir-600 repackaged), flashed them with a new build of DD-Wrt and they keep my phones and computers happy =)

Tried DXLEA, there's no effect. Also kernel wakelocks like XXLF2. I'll test disabling fast dormancy and post the results
[Galaxy S III General] whiper:
I disabled fast dormancy in nwk_info.db and in build.prop.

No significant changes, even secril_fd wakelocks.

But i don't understand why they consume so much cpu.

I've got only one wakelock per minute, fast dormancy works for me.

But these wakelocks use about 10% cpu time regarding total time.

1 hour sleeping = 6 minutes cpu from secril_fd and multipdp
[Galaxy S III General] roisagi:

[Galaxy S III General] nrpetonr:
much higher,between 50 and 100. right after flash all the settings were same and drain stayed at 2 mA for two hrs and the I went to the bed. unfortunately woke up in the morning with phone off, after these 2 hrs drain was constantly above 100 mA. strange, battery history shows system wake of 4 hrs.
[Galaxy S III General] SlimJ87D:
So did you have wifi on? Wifi has been causing kernel wakelocks for lots of people.
[Galaxy S III General] veyka:
What a bunch of silly europeans, who seem to need a reminder to keep it both polite and on topic.

Thank you.
[Galaxy S III General] nrpetonr:
yes, i did all the time. nevertheless, it's really strange, tried w/o wifi, still there. tried different kernel, wifi off and 3g off, drain down to 9 mA, stayed there, put 3g on, stayed on 9mA, tried to work with some internet apps and drain never came back to 9 mA after i left those. trying many different combinations like these and simply can not pinpoint the problem. i know there are multiple threads opened on this topic, but i believe it will not be only wifi related... but i am not an expert, hopefully gurus here will figure it out :-)
[Galaxy S III General] Rob2222:
AFAIK there is no way to read the current on SGS3 yet. I dont know how you got the 9mA value. If its with Battery Monitor Widget its highly unaccurate cause its estimated by % over time.

yes, i do use battery monitor widget. even if it is not accurate, it still consumes simply too much battery overnight during standby, so i would say the figures reported should not be that unaccurate. i just came from hd2 and the drain was constant at 2mA or cca 1% per hour. it is pitty as s3 drain during usage is very good, but this standby drain simply makes it....
[Galaxy S III General] d4fseeker:
Over a measured 10hour period my phone dropped less than 10%, so < 1% per hour. (However a chunk of this is due to BetterBatteryStats itself since each measurement costs a CPU wakeup)

The biggest wakelock culprits were multipdp (3.2%) and secril_fd-interface (2.2%) with l2_hsic (2.1%) and alarm_rtc (1.8%) not fair behind.

All other wakelock sources were well below 1%.

However I have to note that I configured JuiceDefender to switch to 2G whenever the phone is not used and the network strength as good enough with 2-3 bars.

Firmware is ALE8 with SiyahKernel and DXLEA baseband.

This is +- what my gut-feeling told me. However it simply can't compare with the 3-5% battery drain over the same period I had on the S1 =(
[Galaxy S III General] hentro:
so no real impovement here, tried the xxlf5 and dxlea modems with siyah kernal and no major improvement,

[Galaxy S III General] ewingr:
Definitely sounds like a problem.

That sounds a bit like you are saying it is recording the battery drain wrong, as opposed to being a problem where the battery really drains fast.

I suspect there is something I don't understand...Are you saying some have problems, some don't? We all have both problems?
[Galaxy S III General] nativestranger:
He would be right if the over night drain on the gs3 wasn't 5-10x worse than my other 2 android phones with way more inefficient socs. The fact that most members here gets about 1% per hour or more idle drain proves that this is a real battery drain problem.
[Galaxy S III General] ewingr:
Just for my info...what should we expect to get per hour? I did a test the other night, over night, with WIFI on, GPS on, and BT on...and once I got 1.11%/hour loss, and on the second one, I got .98 or so (I had turned off APN that night).

I always did worse than that on my Captivate...until I put SimplyAOKP with DevilKernel on. I got under .5%/Hour with that.
[Galaxy S III General] nativestranger:
I get about 0.1%/hr on my sensation xl. About 0.3%/hr on my nexus one. The gs3 is significantly worse at 1.25% with 3g and 0.9% with wifi.
[Galaxy S III General] ewingr:
Is that based on custom ROMs? Was that with GPS, BT, and and WIFI on? My Cappy was horrible on the stock ROM. But ,not what you are getting on your sensation.
[Galaxy S III General] nativestranger:
On my sensation xl Wifi on or off I would wake up with my battery almost exactly the same as it is the night before. That's on stock on stock Rom. In actual heavy usage my gs3 holds up much better though.
[Galaxy S III General] Rob2222:
Which means 1000hours/41days standby while the phone is online and doing background stuff?!? cmon, NO way... ;)

Even HTC says just 460h standby for the sensation XL.

My Xperia Ray, 2G cell mode, offline (no WiFi, no mobile internet) gets 10 days standby when lying around.

But for that 10 days you have to really don't touch and and don't move around with.

For my experience from SGS2 and SGS3 1%/hour is a normal value for a phone that is online. As soon as you switch off Wifi and mobile internet, you get better results.

One more big problem with that %/h drains is, that the fuel gauge (that creates the % estimation) on the SGS2 and SGS3 are REALLY inaccurate some times. Look at this screenshoot from a SGS2 where the % gets underestimated after rebooting, cause the battery wasn't relaxed.

Shown % and real % was off for 4 hours!

When I had made a %/h check in the middle of the screenhot, I had get 0%/h for 2 hours! Thats a drain! Unfortunately thats not true, there was drain, what you can see at the voltage curve.

So, to get a real %/h measurement, you have to let the phone at home, lying around and don't touch it for the time of the measurement. This takes some days. I don't think, that most people will do that.

BR

Rob
[Galaxy S III General] nativestranger:
Yep that's a rough estimate. Sometimes when I take a short nap of 5 hours the battery shows no drop.
[Galaxy S III General] Rob2222:
Yes, but keep my SGS2 after reboot sample in mind.

The % was totally wrong over 5 hours! If you would check % after reboot and then 5% later, you have a wrong value of 10% per 5h.

In reality it was 30% in 5h (yellow line).

So even a "monitoring" time of 5h can get wrong results in some cases.
