When you ^ say your android os is 60% what is the cpu total time for that 60%

The past couple days my battery drai was wacked from android os at the end of the day it would die from the os running for about an hour and very light use with only 1.5 hour display.

After one of these three things problem is gone 1. factory reset 2. flash over to cognition 3. freeze media hub

[AT&T Samsung Galaxy S II SGH-I777] AndreiLux:
To be honest I don't give a **** about arguments about that. People with older phones like the Desire have 2 days tops of battery life. This phone at release has a load of new components never used in other phones before, and the SoC itself isn't used in any other device. It's the same as comparing a i3 in a laptop to the battery life of some other processor. Fact is if you've even read my post you'll see the hardware is capable of down to 0.3% of battery consumption per hour. You say you're getting 10% in 12.5 hours, you have actually to explain that usage before making such a remark. If it's light usage & Wifi, then that's bad.

And where exactly am I wrong in my claim? I know the drivers are in the kernel. I know it's open source. Improve your reading comprehension before making remarks about me not know what I'm talking about. There is no kernel, ROM, out there that fixes the problem. If you're feeling like going over the source code and rewriting/fixing the drivers please do so. Fact is nobody other than Samsung will go through that effort.

And where did I mention it was the same cause? It was the same effect of those processes bugging out, and it was fixed. I only even linked to it because that other user asked for it.

I won't even argue on that. I've had this phone for 3 months now and Android OS usage is directly correlated with battery life. Do I need to make a timeline with graph of CPU usage of suspend&events/0 to make you see that? I've had phone uptimes up to 4.5 days where I monitored the usage regularly every few hours and where battery would go down in abnormal ways, CPU time of those processes would go up. The phone hasn't even been out that long for AT&T users.

Android OS 80%

On one week old AT&T Galaxy S II, stock rom, seemingly independent of radio and other settings: battery draining at about 10% per hour with virtually no use, Android OS accounting for 80% of drain, Watchdog alerts are from "suspend" and "event/0". My issues match those discussed at Singapore Hardware Zone under "Android OS bug, what it is and what it is not."
[AT&T Samsung Galaxy S II SGH-I777] tboooe:
I was getting very similar drain (5-6% per hour at idle). Do you have any apps installed that is causing high cpu usage or wake locking the device? BetterBatteryStats is a nice app that shows what processes are wake locking your device. In my case, here is what I did:

Factory reset the device

Installed apps back in one at a time and monitored Awake time and wake lock

Turned off Active Sync (I am only syncing contacts and calendar through google, since these dont need to get continually updated I use a Profile Scheduler to turn this service on a few times a day, I use the stock email app to retrieve emails once every hour)

For me, Active Sync (Event Log Service) was causing a lot of wake locks. Once I deactivated, my wake locks went away. I also noticed that Text Free app was also causing a lot of battery drain. Of course I am also judicious with my use of Wifi, GPS, screen brightness, etc. I am not getting <1% battery drain at idle.

Hope this helps!

BetterBatteryStats

Just installed BetterBatteryStats about 30 minutes ago and am letting things sit to see what wakelocks might be my problem. I do (must) use Exchange and have tried various sync settings from once per 15 minutes to push, didn't 't seem to matter, but when I was changing things before I did not yet have BetterBatteryStats installed. Here's hoping I can actually find an app that's causing my problem. Have also tried the advice concerning WiFi sleep (lots of posts say set it to "never", that didn't help me), and am now trying "sleep when screen turns off" just to see if that matters....
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
It's starting to sound like there's something seriously broken with Exchange support in userland... Either that or Exchange ActiveSync sucks, which might be the case because EAS + Google Sync on a Winmo phone used a lot more power than Gmail does on my Android device.

Most of those who are having severe battery drain problems are ActiveSync users.
[AT&T Samsung Galaxy S II SGH-I777] Colton127:
I'm obsessed with battery life and came across two batteries and an external battery charger on Amazon for $25. I ordered it yesterday and should get it in 1-2 weeks. I'll write a review on it if you'd like.

As far as I know, the two extra batteries have a bit higher capacity than the default Samsung Battery. There is also an included charger which allows you to charge a battery while having another battery in your device; which is nice. For $25, I think this is a good deal. Especially when you consider a new iPhone 4 battery is over $50 (I believe it's $100) and isn't even user-changeable; LOL.

Here is the product page, BTW: http://www.amazon.com/Hyperion-Sams...JE8K/ref=sr_1_1?ie=UTF8&qid=1318624441&sr=8-1
[AT&T Samsung Galaxy S II SGH-I777] tboooe:
LOL! Thank goodness I am not the only one obsessing over battery life. I am now getting less than 1% drain per hour at idle. I guess I should be happy with that but being the OCD, geeky type I am, I want to get more! Please let me know how those batteries work for you.
[AT&T Samsung Galaxy S II SGH-I777] Colton127:
I already know one thing: When one of the two batteries are in the AT&T Galaxy S II, you cannot charge them using the USB cable. The phone will try and connect using USB mode instead.

I do believe there should be a workaround or fix for this, though.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
I've identified the kernel code responsible for this, but to be honest - I'm not touching it until I am 100% sure that there is no risk of damaging the phone if this code is disabled.

OS drain

There is a whole thread on the "Android OS" battery drain issue: see Samsung Galaxy S II I9100 > Galaxy S II General > [REF][Upd 14/10] What the Android OS bug is and what it's not

http://xdaforums.com/showthread.php?t=1290020
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
That's already been linked here, and so far, I haven't seen a single I777 user report the specific symptoms experienced by Andrei. Lots of stuff can get lumped in AOS, it's kind of a "catch-all".

1) False reporting of high AOS usage even when everything is fine - this happens to nearly everyone that is having normal drain.

2) It is starting to look like some networks cause the WiFi chipset to fire interrupts way too often. Not a phone bug, but a network bug that just happens to be FAR more noticeable on a phone that is trying to stay in deep suspend mode. Still under investigation - unicast does it, straight broadcast does not, site-local multicast doesn't, need to test link-local multicast.

3) People might have other problems, but it's impossible to tell without a dump of /proc/wakelocks after a severe drain incident.

Things that I have seen as confirmed causes of drain on I777s so far:

1) AT&T bloatware, the background services cause moderate drain, especially SNS and SisoDrmProvider

2) Issue 2 above

3) Misconfigured Exchange email server

4) (special case of 3) Hotmail calendar sync (Edit: A few people have had problems with non-Hotmail Exchange calendar sync, with all other sync functions being fine)

5) Badly written apps - Words With Friends is at the top of the "battery drainers" ****list right now, Facebook is way down on the ****list after being #1 last year.
[AT&T Samsung Galaxy S II SGH-I777] Alucardis666:
Thanks for clearing up a lot of those.
[AT&T Samsung Galaxy S II SGH-I777] L Eric:
Thanks for this!

Now, if I have Words with Friends but it isn't even on my battery usage do I have to worry? I think I may have a minor battery drain but I'm having trouble finding the culprit.

I'm at 36% after 11h and just under 2h screen-on. This seems a little better than before, but I would love getting this incredible battery life that some others seem to get.
[AT&T Samsung Galaxy S II SGH-I777] jcruse03:
I noticed today, after doing a factory reset on rooted stock firmware, that my idle battery life was all of a sudden fine. Android OS was only around 14 % cpu and I only lost 2% in 5 hours.

I was to the point that I was going to exchange the phone so I didn't install any apps and left wifi on but not connected. To make a long story short as soon as I connected my wifi I saw android OS take off and the battery started draining fast with the screen off again.

I never noticed it because it was all set up to connect and never sleep everywhere I was at.

Now I can turn wifi off and check the CPU time for android OS and it changes by only a 5-20 seconds in a 5 minute period. When I connect wifi again it will increase by 3-4 minutes in a 5 minute period. Both with the screen off. I've repeated this multiple times to test.

I'm wondering if this is a hardware issue? I may flash CM7 and see if it happens with that.
[AT&T Samsung Galaxy S II SGH-I777] roadrash7:
After a 9 hour day of work this is what my android os is. When i first got the phone it would be at like 20 to 30 mins. 88 % left if you cant see it. Cog beta 4, DD exp kernal, no oc no uv. Im very happy
[AT&T Samsung Galaxy S II SGH-I777] Alucardis666:
Thanks for posting your experiences.
[AT&T Samsung Galaxy S II SGH-I777] jcruse03:
The same thing happens on CM7. AOS issue disappears with wifi off or when it is on but disconnected. Setting wifi to sleep on screen off also makes no difference the drain and AOS issue still occur.

Can anyone else repeat this? I'm still wondering if it is the phone and if exchanging for the same one could solve my issue. Not using WiFi isn't exactly ideal.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Read the last 10 pages or so of the thread I linked above, and pull /proc/wakelocks and post it here for analysis.

High AOS usage with wifi on has, so far, never been a hardware problem but a network problem, at least on our phone. In AndreiLux's case it was caused by Skype network traffic.
[AT&T Samsung Galaxy S II SGH-I777] roadrash7:
Just want to share how its been going for me with battery life on this beast. Coming up on 16 hours now @ 49% , soon to hit 3 hour display (web browsing,xda,engadget app couple phone calls emails) listened to 1.5 hours of tunes, wifi when browsing , music through bluetooth, data and sync always on (just accu weather wiget and gmail). Im very pleased i could hit 5 hours display on this charge easy. It would be hard to go to a galaxy nexus if the battery life wasnt at least this good. I did freeze and uninstall some things, i dont know if it made a difference but whatever

Looks from your screen shots that you may have a wake lock problem. Get cpuspy and betterbatterystats apps, and look at entropy's thread about battery drain.

Hi guys, I’m going to start off by saying sorry for the questions I’m going to be asking but I’ve tried searching the forums and can’t correct the problems.

First off here is the phones background. I bought a used Galaxy S2 from a previous owner that has it rooted, KG6 and Gingerbread 2.3.4. I want to try a different rom and upgrade to 2.3.5 or higher. I’m finding the battery life and performance of the phone not to be the best on its current setup.

My problem is that when ever I start up Odin and get into the download mode on my phone Odin never recognizes it. I’ve tried using different usb ports making sure usb debugging is on, I’ve even tried a different computer and Odin still didn’t pickup my phone. So next I tried ROM Manager Premium it wont let me backup my current rom even though I don’t want it it says signature validation failure. Also when I try to download a new rom and update it also fails. Please help me out thanks.
[Galaxy S II Q&A, Help & Troubleshooting] jayerfernandes:
If you have CWM recovery, use it. I like GingerMod as its the best combo of stock and aosp, its on its way to 2.3.5 in a few days. Also make sure USB debugging in Application Settings is ticked and anything remotely related to Kies on your comp is killed.

You don't have to clear data or jump through any hoops.

Just go to the phone's main menu/settings/Language & Keyboard Settings/Swype(Swype Settings) and change the language from Espanol to US English.

For some reason the update defaults it to Espanol and all you need to do is switch it back to US English.
[Motorola Droid 3] MadderThanMad:
I actually tried changing the language in swype but even when I choose english it would stay in spanish. Clearing app data is what finally did the trick
[Motorola Droid 3] jwanny10:
Until I wiped the data, menus were still in spanish. I changed from Spanish to English, but the SYM button was SÌM button. And adding to my dictionary was in spanish. Clearing the data was the fix.

Look for sense. Sometimes it uses 90mb. Stop the service.

Also, on sense, use a different scene and remove all the widgets.

Then use go launcher as default.
