As far as I know, this bug is related to gingerbread and not by samsung, somehow it is triggered randomly (some say google maps, others say wifi or games) and the root cause is unknown, that's why some people haven't experience it, a quick temp solution is to restart the device but this is just terrible solution..if you are affected pls help spread the word so the issue becomes a high priority in google, the issue is already raised here since Feb 2011 and a lot of people have already experienced it (I myself experienced it):

http: / / code.google.com/p/android/issues/detail?id=15057

but it is still under medium priority, unbelievable! do you remember the SMS bug? google got pressured when it was spread in forums and news site..I think we can do the same here..let's raid android forums and android news site

it happened to me once...as you said before i restarted the phone and everythnig was normal again..

battery drain was due to wi fi sharing(although it was turned off)..and

Hi mate,

I used madmack's ROM which is based KE7 to enable Arabic.

What does factory reset means? will I loose all this setup? also how do you do the reset?

What would be my options if I want to keep madmack's ROM?

Kind regards,

[Galaxy S II Q&A, Help & Troubleshooting] mtcs:
The battery on my UK Vodafone supplied SGS2 doesn't last long.

The battery usage shows the following:

1) Android OS 54%

2) Email 20% (I have an exchange account)

3) Display 12%

4) Cell standby 5%

3) The rest is divided up as Phone idle and Android System

This is after just over 11hours of it being turned on, with a 3G, no wi-fi, gps or bluetooth, and the battery is nearly drained.

Does anyone know what type of usage accounts for 'Android OS'. I have no idea why it uses so much of my battery. I don't use the phone that much, i'm not playing with apps and fiddling.

The 3G signal is for my Vodafone Sure Signal. Since it's local to my house, the transmit and receive power is very low, far less than if I were outdoors with a 3G signal.

I wondered if the various types of Sync's that are performed in the background are what's accounting for 'Android OS'.

I've turned off the live wallpaper now to see if that improves things, just in case that wallpaper keeps cycling even though the screen is off.
[Galaxy S II Q&A, Help & Troubleshooting] Xero Xenith:
I'm not getting the monstrous drains some are reporting, but still a solid 21% of Android OS plus 5% of Android System (whatever the difference is there). I can't remember exactly if my Hero had the same amount, but I think it was lower than that.
[Galaxy S II Q&A, Help & Troubleshooting] anderssv:
Got the drain. A factory reset fixed the problem, and I'm gradually re-enabling services and accounts now.

Just enabled my second Google account now, and the results are a bit worrying. I'll post back when I know.
[Galaxy S II Q&A, Help & Troubleshooting] Madcow29:
How can you find out the battery usage??? I can't find it anywhere on my SGS2, I want to know too
[Galaxy S II Q&A, Help & Troubleshooting] Madcow29:
Sorry, I've found it...

Mine is (without sim card, wifi on)

Android OS : 16%

For anyone else experiencing this battery drain: Factory reset helped A LOT. Doesn't seem to matter much which sleep policy I have for Wifi either, and all my Google accounts are added now. Will be re-connecting some more accounts and changing some settings gradually over the next days. I'll post back if I find anything that breaks my newfound battery life. ;)

I had this problem on my S as well... seemed to happen randomly. Some days the phone would have stellar battery life, others it would die before the work day was over.
[Galaxy S II Q&A, Help & Troubleshooting] Rooster19:
What's the point of doing a factory reset then loading up all the same stuff you had on it last time which will eventually lead you to the same problem?

[Galaxy S II Q&A, Help & Troubleshooting] stefan442:
I know its a different device but early in the n900s life it also had some battery issues. Id assume it will be down to the same reasons, apps/widgets etc not fully optimised. Ive deleted most of the junk on the phone i won't use. Maybe its all the samsung gaff... ive also read some stuff about latitude being a bit of a battery hog?

Simply amazing this phone, so easy to get on with. Had it a day, not owned a droid device before.

Its running a custom rom, custom kernel, rooted. Have CWM running with back ups saved to my sd card, root apps installed. All ive done today is read read read! :D Just set up adb so i can push some files as i have my eye on a theme that is compatible with villainROM! need to learn about permissions and what to do with the meta-inf now :D

Drain seems to get less for me now.

Still Android OS is @ 58%, System 19%

High values for these are maybe OK in idle (as is my phone for the last 4 hours -> ~ 3% drain).

- event/0 @ 31%

could it be some sort of wi-fi bug ?

noticed that once i'm connected to a network it still scans for networks, every 10 seconds of so.

I'm wondering if there is any reason to scan, as it is connected already..

i was under the impression that it must search only if connection is lost.

i think the bug is worse in SGS2..the bug causes the cpu to suspend and hang and since it's dual core, it eats juice more..read some affected by it turned their phone very hot! i cant believe google is not treating this bug as high priority!
[Galaxy S II Q&A, Help & Troubleshooting] Amkolino:
I have installed XWKE7 on my SGS2 and sometimes the feature "WLAN-FREIGABE" called in german drain my akku very well. (WLAN Freigabe should mean .. Wifi - release or something like that)..

It starts by itself after i charged my device..

i have to stop this process, if not my akku would be @5% at 3pm ..
[Galaxy S II Q&A, Help & Troubleshooting] adamantell:
i dont seem to have any problems.

using phone all day it will last around 12hours, thats internet camera photos gaming sms and calling... seems be ok imo for a smartphone with a masssive screen ( i run full brightness as well )

if i dont use phone, just make 10 or so sms and 5-10mins calling it will last from 0800 too around 2300 ( the next day )

so almost 2days again i think that is ok....

tbh my phone is new and had it just over a week now its going well i charge it ONLY when it "turns off" due to lower then 1% battery, i have never done a 1/2 charge on it.

maybe that helps, also i close down the apps im not using by Active Application icon
[Galaxy S II Q&A, Help & Troubleshooting] nexxus.:
I am lucky (almost) not be affected from that problem.

The only thing i freezed in TB is Wifi-sharing manager cause it appeared pretty often with 10% of usage but i never figured out the function of that program :)
[Galaxy S II Q&A, Help & Troubleshooting] CarpathianUK:
In answer to the original question, no.

I'm on a generic unbranded KE7 that isn't rooted. My day at work is on 3G and at home I'm on my wi-fi.

If I use the phone heavily the battery goes down at a rate that is reasonable but if it's on standby with it's screen napping then I can easily get two days or more from it with mail syncing etc going on too. My phone doesn't get very hot (ranging between 22 and 31 degrees according to the System app) even if being used heavily.

So no, regardless of what is listed as running or having been active, I think it's all quite reasonable.

Example? Five hours of use on the current charge from full including downloading apps, music playing, fiddling with the config a bit and tweeting etc and and I'm still on 93% battery.
[Galaxy S II Q&A, Help & Troubleshooting] Medulla_Oblongata:
I seem to be having this problem as well. The battery does not last over 20-24 hours. I don't heavily use the phone. Just the occasional text messaging (SMS & Google Talk), 2 GMail accounts synched that is all.

There has to be a fix for this, other than disabling every feature and never use the phone :/

How do some of you get to use the phone for up to 4 days?
[Galaxy S II Q&A, Help & Troubleshooting] OrionCarl:
nope as u can see battery is not a issue..mobile date on 24/7 everything updates every half hour music on txting ect.....
[Galaxy S II Q&A, Help & Troubleshooting] Medulla_Oblongata:
Hmm it seems I jumped to conclusions too fast. Found out that I was still signed into Latitude which was active pretty much all the time. Once being signed out, and 24 hours further I have 70% left.

Display: 36%

Android OS: 22%

Cell standby: 18%

Phone idle: 12%

Internet: 4%

Android System: 4%

Mediaserver: 3%

Wi-Fi: 2%

The things I've done (light usage):

- a bit of text messaging

- web browsing for maybe 30 minutes

- roughly 10-15 minutes of youtube

- Wi-Fi ON all day

- Google Talk ON all day

Question: why is Wi-Fi sharing and Wi-Fi sharing manager always running? And can I disable it?

Question 2: what program are you guys using to take screenshots of your phone?
[Galaxy S II Q&A, Help & Troubleshooting] OrionCarl:
press home and power button to take screen shot m8
[Galaxy S II Q&A, Help & Troubleshooting] Gokudera:
I have experienced this bug twice. The first time I had simply disconnected my phone from my laptop after it had fully charged and left it alone whilst I slept. In the morning it had gone from 100% to 14%.

The second time I had left my music player app paused upon arriving at work. 5 hours later my battery had drained, and I remembered to take a screenshot of the battery usage.

The first time I was on stock firmware, the second time I had upgraded to KE7.

Incase anyone wanted to know what this bug looks like, behold:
[Galaxy S II Q&A, Help & Troubleshooting] chadlondon:
When I look at the battery meter it says Android OS has used CPU for 45% of the time, 1h44min - which sounds about the time I've been messing around with it since charging it.

Does this sound right? sorry for the dumb questions i'm new to all this android stuff.

was expecting amazing battery life out of the box.

Before you do that try this

1. Start Odin

2. Plug USB cable into pc

3. Power off the Phone.

3. Pull the Battery.

5. Plug USB cable into Phone.

6. Press and Hold: Volume UP + Volume DOWN + Power, all at the same time.

7. Re-insert the battery.

8. The phone will power now, when the screen starts a cycle of going to a BLACK screen, release ONLY the POWER button.

9. When you see the download icon release the volume buttons,

10. Odin back to stock by putting the PIT file into the appropriate area and the .tar in the PDA area.

I have tried to flash InsertCoin A2SD v39. After successful allign 1gb ext3, wipe and succesfully flash the rom, then rebooted. It got stuck at HTC splash screen for more than half hour. Tried to wipe and reflash again, still the same.

So, the questions are;

1. Is latest radio required? I have 5.11.05.27 with PVT4 S-ON

2. Is Amon-RA ver 2.0.1 required? I have RA-Desire 2.0.0

3. Is it required to flash 1.0.5 stable before flashing nightly?

I wanted to try this ROM....currently I have Redux 1.2.
[Desire Q&A, Help & Troubleshooting] 4rm45:
1. I think InsertCoin requires s-off

2. I've always used 2.0.1 and worked fine

3. You don't need to flash stable before nightly
[Desire Q&A, Help & Troubleshooting] axbilly:
Ok...perhaps i can try with amon-ra 2.0.1. But S-Off...I try to avoid that. Too many things to do.. i have to flash with non a2sd rom, than alpharev.
[Desire Q&A, Help & Troubleshooting] zk7513153:
two ideas:allign EXT3 Not for 1GB, turn a another recovery.
[Desire Q&A, Help & Troubleshooting] davebugyi:
Answers for you questions:

1. Yes, it is required to avoid all radio related problems (call dropping, compass, mms etc) and possible bootloops. However, it may work with your radio, too.

2. No, amon-ra is not required. You can use CWM, too - but newer version required (at least 2.5.1.8 - I'm using 3.0.0.5).

3. No, you needn't to flash stable before the nightlies.

[Desire Q&A, Help & Troubleshooting] axbilly:
ok davebugyi...i definitely have bootloop because the flash was indeed succesful. But upon reboot...it never get pass the HTC splash screen.

I have PVT-4, so no CWM for me...that is why i have amon-ra 2.0.0.

now that v40 is out, and clearly say that it is recommended with latest radio, I suppose we can assume that it is the radio.

Only way to find out is to try it out...If I'm brave enough.

So this is the plan. Full wipe --> Flash ROM --> Flash Radio.
[Desire Q&A, Help & Troubleshooting] davebugyi:
Sounds alright. Btw, CWM 3x is working with PVT4 devices AFAIK. But don't change it since you have AmonRa.

What do you consider an over heat temperature for a phone?

My g2 over clocked @ 1.42ghz reaches 108 max when playing emulators and 3d games, is that consider over heat?

T-Mobile G2 1.42 GHZ
[G2 and Desire Z General] lainvalenajr:
Nope overheat would be like 112 or once your phone turns off its self
[G2 and Desire Z General] androidfeen809:
So could that be reason for reboots on my previous G2 where temp would reach even 115?

I remember the sidekick lx 09 use to have the overheat problem and sidekicks usually warn you with a thermometer. Sign where the battery sign goes. I once put my phone in the fridge and forgot about it in the and left it there freezing for a good hour, luckily it didn't damage but it had ice flakes all over....

This may sound stupid but is there such thing as under heating a phone or over cooling it? Cuz in the winter phone temp is usually very low even when I play emulators going to college @ the train station

T-Mobile G2 1.42 GHZ
[G2 and Desire Z General] craiglay:
Maybe, it depends on the situation. Very low temperatures will affect the LCD temporarily and maybe cause poor battery efficiency but shouldn't affect the running of the phone too much. If its cold outside, the phone will be able to dissipate the heat more. :)

Transition between high and low temperatures can significantly affect it though. I think its high temp to low temp, the air will condense and deposit moisture in the phone. Again, its probably nothing to really worry about, its only extreme temperature change that does that normally.
