[Galaxy S III Q&A, Help & Troubleshooting] foo:
I have to admit, I never cared about the battery status before, so I was curious and looked it up in my phone for the first time. I currently own an Huawei Ideos X3 (it's total crap - S3 is pre-ordered already :) ).

Battery status says: 43% "cell standby" and 42% "device idle" battery consumption. Actually this is not surprising for me at all, as I did almost nothing with my phone during the day but I know I have to charge it every day or two anyways.

So if I would not touch my phone at all, would not make any calls, not switching it on, etc. shouldn't the "phone standby" & "device idle" battery consumption be near 100%?

Don't get me wrong, but the question for me is not the consumption in % of some components but the question of how long it takes until I have to charge my phone again.

GSM Arena says that the battery life is quite good, so I'm a bit confused now. :)
[Galaxy S III Q&A, Help & Troubleshooting] Oli2k:
It's either a reporting bug or the cell standby is using a lot of power
[Galaxy S III Q&A, Help & Troubleshooting] minhqp107:
Bump. This is definitely a bug cause in no way the cell standby is supposed to use more power than the screen.
[Galaxy S III Q&A, Help & Troubleshooting] w7ldc7de:
40% battery usage over 11h50m

Call standby 62%

Android system 12%

Screen 10%

Other 24%

Usage for standby is definitely too high. I used the phone a bit just before going to sleep and standby has eaten through about 30% of my battery just sitting there doing nothing.

at this rate if i left my phone alone for just over a day standby would drain all the power.
[Galaxy S III Q&A, Help & Troubleshooting] BNI:
same issue here. Cell standby drains the battery more then display or something else.. think we have to wait for a new firmware / radio rom... greetings from germany
[Galaxy S III Q&A, Help & Troubleshooting] Oli2k:
Hopefully it won't take too long as it does seem a widespread problem.
[Galaxy S III Q&A, Help & Troubleshooting] Foggie:
Think I got same issue here on O2 in UK.

Just checked after 4hrs 33mins use, Screen on is 22% and Cell Standby is 29% and yesterday after 14hrs the Cell Standby was 48%.

Think I'll try flashing a different modem.
[Galaxy S III Q&A, Help & Troubleshooting] BNI:
there are different rom's available yet? Anybody who test the different roms for batterydrain?
[Galaxy S III Q&A, Help & Troubleshooting] Foggie:
I just installed Omega ROM V4 last night so haven't had much chance to say if battery drain overall is better. But the Cell Standby having the most % drain appears the same. I've Just flashed LEF modem (Did have LE8) so will see how this one goes.
[Galaxy S III Q&A, Help & Troubleshooting] Oli2k:
I'd be interested to hear how it goes
[Galaxy S III Q&A, Help & Troubleshooting] BNI:
look @ the picture.. i switch to flight mode for about 2 hours, in this time it just lost 1%... damn, for a few days i thought i own the perfect phone :P
[Galaxy S III Q&A, Help & Troubleshooting] Foggie:
I checked the phone after not using it for 8hrs 42mins and it has lost 8% of which cell standby used 85% (of the 8%). Does that seem fair usage, I do have WiFi enabled and am wondering if the percentage for this power being combined into the Cell Standby total? If they are combined and maybe bluetooth too, then I guess that isn't so bad? I have noticed the signal is poorer using the LFF modem over the LE8 on O2.
[Galaxy S III Q&A, Help & Troubleshooting] DrewVL:
Mine always sit at 24% on Cell standby
[Galaxy S III Q&A, Help & Troubleshooting] BNI:
in the german Forum "Android-Hilfe" they talk about the bad baseband-rom, too. You could reduce the drain if you switch to 2G use. But thats not the best solution.. we have to wait for baseban-rom!

I'm coming into this thread a bit late. I skimmed through (not all). Does this Standby issue still apply if the user is rooted and controlling the CPU?
[Galaxy S III Q&A, Help & Troubleshooting] Oli2k:
Yes it does
[Galaxy S III Q&A, Help & Troubleshooting] zantekk:
I added this to my build.prop

ro.ril.fast.dormancy.rule=0

to disable fast dormancy. will report back if it helps.
[Galaxy S III Q&A, Help & Troubleshooting] Oli2k:
It's not meant to change the drain
[Galaxy S III Q&A, Help & Troubleshooting] Lennyuk:
Fast dormancy is OFF by default on this phone anyway.

I have been testing adding ro.ril.fast.dormancy.rule=1 for a few days now and it does seem to help (but depends on your own carrier)

turning this feature on and your carrier not using it should not make things worse, it should just make things better if your carrier does support it.

More testing required though.
[Galaxy S III Q&A, Help & Troubleshooting] matttye:
Battery life is by far the best I've had on Android. I get about 4 hours screen on time, but like you say it could be a lot better.

Right now I've had 2h 3m screen on time and I have 64% remaining. Cell standby is using 14%, screen 39%.

I use Tapatalk to visit forums with a dark theme now so the screen uses less power :)
[Galaxy S III Q&A, Help & Troubleshooting] danarama:
I've done that with tapatalk since day 1 ;)

Yes its pretty good battery. The screen is surprisingly resourceful. Of course the battery is bigger than the desire so it's hard to compare.

All I can say is that it definitely competes with my desire rom release
[Galaxy S III Q&A, Help & Troubleshooting] matttye:
Do you find that the battery % gets stuck sometimes? Mines been on 64% for about half an hour now, pretty sure it's not right!
[Galaxy S III Q&A, Help & Troubleshooting] Lennyuk:
Yes I have noticed this every now and again
[Galaxy S III Q&A, Help & Troubleshooting] matttye:
Rebooted and it dropped to 48%... Will be a problem if I go out thinking I've got plenty left when it's really lower than it says!
[Galaxy S III Q&A, Help & Troubleshooting] danarama:
My % always looked to be fine. I notice if I boot into recovery a coupple of times ina day and do some really nominal flashing, I lose about 15% battery per 2 flashes.

But that doesn't surprise me. That behaviour has always manifest itself on otehr devices....

But perhaps it is an indication of the issue you mention. Every time I look at it, the % is different though so its hard to confirm
[Galaxy S III Q&A, Help & Troubleshooting] matttye:
I'm on stock atm so it might be an issue with the stock firmware.
[Galaxy S III Q&A, Help & Troubleshooting] danarama:
Could be. Lenny's Signature says he is stock too.

Battery doesn't drain on Standby. Turn off wifi and data leaving just phone signal on. The battery goes forever.

As soon as data or wifi are activated, drain begins. Just hope it's not hardware.
[Galaxy S III Q&A, Help & Troubleshooting] danarama:
If its hardware, it can only be that it pulls too much power, which I assume could be fixed by restricting it using software
[Galaxy S III Q&A, Help & Troubleshooting] zantekk:
Same problem here.

I lost 10% over night with data enabled.

1% in airplane mode.

wifi off.
[Galaxy S III Q&A, Help & Troubleshooting] danarama:
I'm sure there is partly a reporting error here.

Daily, my cell standby says 10% no signal. Working tgsy out today would mean 1hour. I've been checking regularly and havent noticed any time without signal. Added to which, there are no red areas fir signal on the battery graph, like I get going through a train tunnel

Sweet! Battery issues finally stopped with the omega 6.0 rom. The cell stand by use has now halved. I think it's because of kernel XXALF2 being introduced into the omega 6.0 rom.

---------- Post added at 02:16 AM ---------- Previous post was at 02:11 AM ----------

Cell stand by now using 25% of battery in 24 hours after flashing Omega v6.0. Does that seem reasonable?
[Galaxy S III Q&A, Help & Troubleshooting] Baldilocks:
Yes, it sure does. :)

Whatever it is, Samsung doesn't seem to worried about it, as battery life is generally VERY good, even with the 'bug'.

I still had issues with the XXALF2 and XXALF6 kernels.
[Galaxy S III Q&A, Help & Troubleshooting] MrSimtang:

Me and my girlfriend received our S3's Wednesday. (T-Mobile, UK, 16GB White)

I flashed both with Omega v5.2 straight away.

Yesterday, she had 73% left after 10 hours, Cell Standby had taken 51% of that. (cell had taken 13% in 10 hours)

My phone had the same 73% but only 20% cell standby, both have wi-fi on 24/7.

I've now flashed to Omega v6.0 so i will update later with the results.

if your carrier is not support FD..or use old FD protocol you need to disable it.

about FD: http://www.nokiasiemensnetworks.com...ent/Smart_Lab_WhitePaper_27012011_low-res.pdf

for Root phone only

you will need sqllite3 binary (you can do this also from PC , copy nwk.info.db to your pc and then upload to your S3 after editing)

or using

sqllite editor --> go to dialler storage --> nwk_info.db

https://play.google.com/store/apps/d...qleditor&hl=en

download sqllite3 for PC:

http://www.sqlite.org/download.html

go to:

#cd /data/data/com.android.providers.telephony/databases/

#[pathtoyoursqllite]/sqllite3 nwk_info.db

# sqlite3 nwk_info.db

sqlite> select * from nwkinfo;

sqlite> select * from dormpolicy;

45001|SEC Test|5|5

sqlite> delete from dormpolicy where plmn="45001";

sqlite> delete from nwkinfo where plmn="45001";

you need to delete all row in above table (all value in dormpolicy and nwkinfo need to be empty)

add to /system/build.prop:

ro.ril.fast.dormancy.rule=0

do it on your own risk

My battery drain is just fine. Its when the heavy applications kick my battery in the nuts that im a bit worried
[Galaxy S III Q&A, Help & Troubleshooting] Minoza:
Do you guys realize at all how this works?

I mean, cell standby, percent shown means how much is used of the current % usage... If there is 50% percent of battery used, and 30% by cell standby, that means that 30% out of that 50% in total was used by cell standby, not that cell standby used 30% of battery, are you even aware of that?

If your phone's screen is off most of time, it is normal that the cell standby will be high in this list then. That doesn't mean it drains your battery it just shows how much of used battery was used for cell standby...
[Galaxy S III Q&A, Help & Troubleshooting] Baldilocks:
........which is a LOT higher than on every other Android phone I've ever used. My Galaxy S2 for example rarely got about 15% Cell Standby even with not in use for 8-10 hours.
[Galaxy S III Q&A, Help & Troubleshooting] danarama:
We are aware of how it works, thanks. The issue is that even with high screen on time, the cell standby can exceed its usage of battery. The radio is using much more cell standby than any other phone. Not just proportionally, but totally.
[Galaxy S III Q&A, Help & Troubleshooting] sxi200:
Correct. But I have my suspicion that its some reporting change or that wifi and data are bundled with radio.

At night I switch off wifi & data. Battery barely moves. So the radio seems to be quite efficient. With them on I lose 10% or more.
[Galaxy S III Q&A, Help & Troubleshooting] danarama:
Indeed. If its a reporitng issue, we also need to know.

Its worth noting though that DHCP requests arer under "Android OS"
[Galaxy S III Q&A, Help & Troubleshooting] matttye:
I hope it's a bug :p

Some people are reporting that updated radios have improved the situation for them, so it could be.

Battery life is acceptable to me but a couple of extra hours wouldn't go amiss :D
[Galaxy S III Q&A, Help & Troubleshooting] Minoza:
Aye, as I've replied in the other thread, sorry for pointing out obvious then. :p

My battery holds up pretty well, I didn't even bother to look at my stats from time to time since I'm more than satisfied with the time I get from a full charge. I don't have wifi on all the time though...
[Galaxy S III Q&A, Help & Troubleshooting] Rob2222:
Hello,

CELL STANDBY is just a miscalculation of the battery statistics, as AndreiLux postes here already: LINK

The real battery drain is NOT AFFECTED.

The battery statistics just think that radio consumes 34mA, which is a wrong entered value from Samsung.

Radio drain on similar devices is usually around 2~5mA, so it really seems, Samsung wanted to have 3.4mA there.

Cause of that the stats in battery statistics are wrong.

I have corrected that value in my phone and all stats are fine now.

I'm sure this will be fixed in any next update.

Custom ROMs already have fixed this value.

[Galaxy S III Q&A, Help & Troubleshooting] Baldilocks:
Not really. My GS2 would would be on my night stand while I slept for 8 hours and use only 1 or 2% during the night. That was with wi-fi on.
[Galaxy S III Q&A, Help & Troubleshooting] danarama:

[Galaxy S III Q&A, Help & Troubleshooting] zantekk:
not rly. with my gs2 I got about 0.1% with 3g enabled.

When I switch into airplane mode, I loose 1% overnight.
[Galaxy S III Q&A, Help & Troubleshooting] zigson:
When I'm the UK, cell standby drains my battery at 3%/hr, and when I'm in SA, it's 0.3%/hr. Changing phone modem a couple of days ago has reduced my drain in the UK to 1%/hr.

I disagree with the notion that standby drain is a miscalculation, something is causing higher drain on certain networks for sure.
[Galaxy S III Q&A, Help & Troubleshooting] danarama:
I dont know, it sounds plausable to me. Even if you're losing 3% an hour true drain, that doesn't mean its 65% or whatever over a full cycle of battery with several hours screen on.

It could be that yes, baseband uses more power depending on signal (This is a given) or more than other phones too (Seems possible) AND a miscalculation,
[Galaxy S III Q&A, Help & Troubleshooting] AndreiLux:
While it is a miscalculation, I never said real drain is not existent.

I'm just saying that the battery statistics are absolutely useless in terms of percentages and anybody basing their battery consumption on that is wrong. However, the battery percentages (Battery level) themselves are correct so if you do lose a lot of % in a short period of time, then it is a problem, either by software, or the modem.
[Galaxy S III Q&A, Help & Troubleshooting] danarama:
Where is the miscalculation stored please? I cannot find the .xml file in question
[Galaxy S III Q&A, Help & Troubleshooting] AndreiLux:
\system\framework\framework-res.apk\res\xml\power_profile.xml

It is inside of an APK so if you want to edit it you need to unpack it, change it, an repack it. Change the 33mA value for cell idle to something more realistic (2mA for the S2), and you'll suddenly have no more high cell standby %... And by the way: the CPU values are completely off too, so changing the cell idle value won't magically make the statistics correct.
[Galaxy S III Q&A, Help & Troubleshooting] Rob2222:
The SGS2 had a optimized firmware after 1 year, the SGS3 is still at the beginning. As soon as I am online (Wifi/3G) a battery drain of ~1% per hour is normal for me. At SGS2 and SGS3. It heavily depends then, which apps you have installed, how often they wake the phone and how often they communicate. So in my opinion it's almost not comparable.

But if you want to continue to seek for a cause... do what you want. ;)

For me the issue is clear.

@AndreiLux:

CPU statistics in ALF2 are this:

<array name="cpu.active">
<value>577</value>
<value>408</value>
<value>249</value>
<value>148</value>
<value>55</value>
</array>

So they are better than in your examined file, or?

Hey Rob, did you use apk tool or apk manager to recompile? I assume you didn't have to sign the apk?

Not familiar with samsung yet
[Galaxy S III Q&A, Help & Troubleshooting] AndreiLux:
The CPU statistics are the same, so you see how ****ed up they are. But because we have 13 steps in stock kernels and 17 steps or more on custom kernels, all the rest of the CPU states are being populated with the last step value; i.e. 55mW, which is wrong. You can check the values without opening up the XML with Badass Battery Monitor which has a preference to edit the manufacturer provided profile values.

Maybe this is the reason for my rather heavy battery drain?

There is no drain in cell standby, I got no problem with it. Check your wakelocks maybe other apps are draining your battery, checked mine before my battery drains 20%+ overnight(deleted unwanted apps and disabled useless apps A.K.A. bloatwares).

Now my battery drains only 3-4% overnight when I sleep 8-10hours.
[Galaxy S III Q&A, Help & Troubleshooting] BNI:
I know, but, if I enable flight mode and activate wifi/wlan, i just lost 3% over night.. sync enabled! If I do this with 2G i lost 15-20% and with 2G+3G its over 20% ... i definitly know that the power consumption of the radio is too big!

My Galaxy S i9000 (with the same apps, the same location, the same provider) lose less power at 2G/3G..

example:

Galaxy S3 i9300 Android 4

Wlan on, 2G off, 3G off: over night: uses 2-4%

Wlan off, 2G on, 3G off: over night: uses 15-20%

wlan off, 2G on, 3G on: over night: uses 20-25%

Galaxy S1 i9000 Android 2.3x

Wlan on, 2G off, 3G off: over night: uses 2-4%

Wlan off, 2G on, 3G off: over night: uses 6-8%

wlan off, 2G on, 3G on: over night: uses max 10%

The traffic is under 1 MB per Night, the Mail apps are "sleeping", only Whatsapp and some other services are running.. I do not know why there is this big difference to the old galaxy s1 ...
