Not trolling, if you flashed something you maybe should consider wiping your battery stats, even if you did it last time you flashed.... here is a typical day for me on goodness, which is ff18 based, perhaps as venum suggested earlier in this thread some research is required on your end to solve your issues, I can't tell you what works for me and expect it to work for you as well since we all use our phones differently... and yes I'm OK with Android using 24% of battery as I've got well over 12 hours and have yet to use 50% battery... and lastly that screen time brightness is at 100% the whole time, so I'm not babying it or anything, I was outside all day and needed it that high just to see it, its sunny as hell here today

Edit... I feel I should add I just flashed this rom a week ago and have not tweaked or optimized anything, the only thing I remembered to do is turn wifi off when not in range... these are bone stock settings, including syncs, etc

That it is good sir, I came back to it a week or two ago so I could try out agats newest kernels and I just hit 16.5 hrs with 3 hrs screen time on it and 45% battery left... which is why I've been suggesting it in every OTA gripe thread... battery on ics can be great with very little effort, like i said earlier i havnt even bothered to tweak it yet. ..goodness is awesome, team Noc does great work...I'd be on it all the time if I didn't wank some aokp here and there

Extended battery?
[Samsung Epic 4G Touch] cp320703:
nope stock battery, no way I could deal with all that junk in the trunk plus I don't rock a case...

Was looking through my screncap folder and found this one from one of the old ff11 goodness builds, again on stock battery....
[Samsung Epic 4G Touch] fredrick1213:
Wow! You just motivated me to flash it. My only issue is I absolutely hate themed ROMs but I just read that a stock theme is in the works so I get the best of both worlds :D

On on agats 2.3 kernel as well, I'm sure that helps with it too, oh and op of this thread, have you tried ff11 yet? Still has exchange and I've seen more than one person who didn't like the OTA go to that, it was pretty solid
[Samsung Epic 4G Touch] geolemon:
Also-

On the stock ICS, since wiping - it hasn't solved any of the issues with things either force closing (Apex launcher did this both before, and after wipe), and still seeing the odd behavior listening to music. First time I launch the music player, I'm seeing two things:

1) I have a desk dock at work - I dock my phone, and where the home dock screen came up instantly on GB, on ICS this takes between 5 and 10 seconds to launch - I see my lockscreen during this time.

2) When I pick a song and play it, it'll start playing for maybe 3-4 seconds, then inexplicably stop. The music player is still open, but the pause icon turns into a play icon. So I poke it a second time, the song restarts and plays maybe 5-6 seconds, then stops again. Third time it usually keeps playing.

Also, I haven't tried to use my camera in the past few days, but I noticed the camera force closed a few times with a message box (similar to the popup when something is granted superuser access, near the bottom of the screen) saying something along the lines of "media server crashed. Restarting".

All this, coupled with the Android OS using roughly 50% of the battery drain makes me think there's something going on.

I've performed wipes and other blind/nonspecific steps that are general.

What's my next steps for drilling into this, to discover what's actually going on, to find specifics to address?
[Samsung Epic 4G Touch] someguyatx:
I looked at your battery stats in the OP since you called me out for busting on ppl for crying about the update. Based on the stats alone I see you are using a profile manager called probeez. Uninstall it for a few days and see what happens.

It takes a second to toggle things on and off when you are done with them. I assume you are not leaving wifi, 4g, bluetooth or gps on when the phone is idling. I use my toggles like mad and I dont even think about it. If you are in a bad signal area get data enabler widget and turn off 3g too.

My other suggestion is to back out of apps when done with them if you don't plan to use for a while. Bottom line I get good battery life because I manage my phone and its become second nature. I am also rooted and I get rid of apps and widgets I dont need.

I have tried profile managers, task killers, juice defender and all the other stuff thats supposed to do it for me but I cant find anything to do it better than me. And I do not cripple my phone, email and gmail auto sync and location services are on and I have weather and stuff updating regularly.
[Samsung Epic 4G Touch] geolemon:
Hmm. I'm not sure what a profile manager is, or probeez.

I'm not seeing it in the application list :

I'm using Apex launcher - i was using go launcher before it was suggested to try Apex. I don't believe either allows you to create profiles (or, at least, i don't use them).

The only other thing tied to the concept of a profile is the new Sprint ID thing built into the update, that lets you switch between Touchwiz and stock Google launcher. Do you think this could be it? Not sure if i can, or should, uninstall that one. Thoughts?

Sprint ID is one of the apps that I've been seeing force closes - not because its an app you go into, but instead suddenly a pop up appears "sprint id has stopped responding".

Note again - besides Apex launcher - the comparison here is "stock GB" to "stock ICS". The phone is the same as before, the only difference is the update.

This is from your own battery stats and it caused 118 wakelocks

com.probeez.liteprofiles.AutoProfileService (com.probeez.liteprofiles.Setting Profiles Lite): 8 s (8 s) Count:118 0.0%

The thing that really disturbs me is this 1381 wakelocks wtf?

SyncLoopWakeLock (Android System): 8 s (8 s) Count:1381 0.0%

https://github.com/asksven/BetterBatteryStats-Knowledge-Base/wiki/SyncLoopWakeLock

I suggest you review each line and figure it out on your own from here. Seriously though just start fresh. Spend about an hour to load up all fo your apps again and fix your settings and it will be worth it. Go to the development section and grab sfhubs 1click ff18 and go from there.

I just about flashed back to GB due to crap battery life on ICS update. Even after diasabling Exchange pushes, setting brightness to minimum, wifi off with screen, auto_rotate off and using SetCPU to minimize voltage/freq I got maybe 50% life vs GB.

Then I backed eveything up and did the factory reset...Holy crap! It's like having a different phone. It's at least as good as my tweaked GB Caulkin rom battery life.
[Samsung Epic 4G Touch] kingsway8605:
I am considering doing this, I just know as soon as I go back to gb and reflash all my apps, jb is going to leak.

fyi, Sprint and Samsung are aware of the issues with the update and are "investigating" them. I have confirmation from a reliable source of this (ie not a store tech but someone who would know).

From my own battery stats? I don't have anything installed or running that I didn't have installed before on GB...

I've got BetterBatteryStats installed - that's what this is? Very interesting. If there's an issue, then that would point to a bug specific to BBS running on ICS. That's a helluvalotta wakelocks.

I may start fresh to see what happens, I followed the process of

1) going back to a GB nandroid then removing root

2) upgrading to ICS following QBKING77/sfhub tutorial/thread

3) rooting

4) using autoroot tool to add CWM recovery (safe version)

What would change in this process I suppose would be to do a full wipe prior to step 2, otherwise this process was pretty clean the first time. Maybe I'll uninstall BBS first - is anyone using betterbatterystats on ICS, are there known issues? (I haven't read that links yet, I will during lunch at work)

I'm seeing no benefit to doing the wipe after the fact, though, so I'm a little skeptical... In fact, things are still crashing, possibly more than before. I couldn't even launch the XDA app today, and I prefer using that to the web client. If I can get back in after rebooting my phone I'll put up a few more screen captures I took, other things crashing, showing the "...has stopped responding" popup box. I'd never seen one of these prior to the ICS upgrade. I suppose it could be due to BBS waking and interrupting active processes, I don't know.

Thoughts?

and thanks. At least I feel like I'm inching forwards!

PS - if I could figure out where those Exchange account advanced sync settings were (mainly sync schedule with peak/off peak days/times), and add them after the fact, I'd be on a different ICS build. It's the only reason I'm on a stock-based build. Any ideas there?

EDIT: SyncLoopWakeLock - says this IS new to ICS: "was introduced starting in 4.01." and resolution includes reviewing accounts that sync. I have most of my accounts set to not sync, and in fact that's why I like that Exchange account sync schedule option for "peak" and "off peak" hours - I have mine set to a "peak" schedule of 8am-6pm M-F, where it doesn't sync at all (I'm at my desk at work - no need, and I get Emails constantly), so effectively even that account is only syncing after hours - and only every 15 minutes.

However, I'll review, I'll update if I find anything. There's definitely other accounts in there, facebook, google, Gmail. Thanks again for the link.

I use Touchdown for exchange mail and after factory reset just reinstalled it from GObackup. (I don't sync Google or any other accounts because I fwd them all to my exchange account.) None of my exchange push/sync/eak settings changed at all and my battery life easily was doubled after reset. No clue why.

Today I turned on full push and set wifi off to never and still had more battery left after 12 hrs than at 7 hrs before the factory reset. (Note that setting the wifi to always on totally kept me out of deep sleep and cut battery life by maybe 40% without noticable benefit, which ptetty much sucks.)
[Samsung Epic 4G Touch] geolemon:
I was finally able to get into the xda app without becoming unresponsive.

Note i never had a single app become unresponsive with the stock GB ROM.

I've done a factory reset, wiped stats, all symptoms (other than Swype and copy) remain.

What's the next step? Living with this is simply unacceptable, as it has made a formerly superior phone perform worse in almost every respect than my old HTC Magic. Not acceptable.

(Other apps have done this as well, including the launcher even - not sure what's causing the conflict, would like to troubleshoot)

I used to get well over 20 hours without issue, without making an effort. Now...

This simply isn't acceptable, and 5 pages later, it seems like there aren't any additional leads for troubleshooting?

Performing the wipes/reset didn't yield any improvement.

I'd love a direction to go from here to troubleshoot (rather than blindly wipe/clear/reset/etc). Any suggestions are appreciated of course.
[Samsung Epic 4G Touch] benchsitter21:
I was having similar issues to you after manually updating to ICS, I am on stock ICS non rooted. I even did a factory reset and that helped slightly for about 2 days then I was back to 7-8 hours battery time with little use and the Android OS as the culprit. I have found a few tweaks that have pushed me to about ~20 hours on a charge consistently. They may not work for all but have at least given me 20+ hours on a single charge. I did the Partition cache clear clear (this does not factory reset your phone, and i actually did not lose anything expect a few passwords and my bookmarks), to do power off, then power on holding the volume up until the green android figure appears then select wipe cache partition. The second change i made was to select sprint only for roaming and not automatic. Last item was to un-check anything that did not require synch under accounts and un-check the automatic time zone and date and time.

Battery Issues

Posted in a different forum, thought I would try this one.

Got the ICS update. Running a completely stock E4GT with a 16GB SD card. Battery is now completely shot. I will be working on the phone (browsing the internet) and the phone will just shut off (it had something like 66% battery life). Then, when I plug it in to get it to work and start it back up, it says I have like 1% or 2%. Turn it off and back on and I am back up to 66%. Then it dies again. I got Better Battery Stats and it is clear: The line goes from 67% to zero, and a few minutes later from zero back up to where I am.

To top it all off, it did the same thing at the Sprint store just now. They said hard reset. Uh, no.

Camera now won't work; it keeps saying "media scanner running" and then backs out of the camera app.

Can anyone help with suggestions on what to do?
[Samsung Epic 4G Touch] geolemon:
First, try pulling the SD card, reboot the phone and retest these things.

The SD card needs to be formatted from the phone, I believe.

Otherwise it can't quite read it, media scanner will be running, failing, trying to address this card.

It's a quick test to just pull the card entirely temporarily to see if that resolves your issues.

Thanks guys.Just starting working fine after I removed an app that was hanging.
[Samsung Epic 4G Touch] geolemon:
Thanks, I haven't heard of him/her/that, but I'll do a little reading, and check it out.

I want to try a totally clean "wipe first" approach with the stock ROM first, I'm just nervous because of all the talk of "safe" recoveries and all that - I believe I'm on one, but don't want to brick my phone.

I really have no tie to stock though (I was running Cyanogenmod roms on my old phone for years), other than that Exchange peak/off peak synch schedule. And that may seem silly, but during the day, I get a LOT of work Email.

What app was hanging?

And maybe more importantly - how did you identify it? I'll try the same thing.
[Samsung Epic 4G Touch] noobie100:
It was a game called "Gone Fishing." Every time I would start the phone, I would get the notification that "Gone Fishing has stopped working." I removed it, and literally have had no problems since then.

Interesting thread...

Hey all,

I don't chime in here often but I've been following xda threads for years and this ICS battery issue has me stumped...I scanned through these posts and I don't see where anyone has installed CPU Spy...

So far I've installed after full wipes and running Caulks wipe all:

Stock OTA update

Blazers latest ROM

Venums latest ROM

Sfhubs Stock rooted FF18

Caulks and Venum "super fast" FF18

and I've tried installing:

Agat's latest kernel

Venums Latest kernel

and Sfhubs Kernel from the stock FF18

I've even tried every governor in each ROM, and every scheduler

And I'm finding the EXACT same thing on all of these, when it comes to battery life that is...And I've run the GSAM battery monitor and the other one - better battery stats I believe it's called...and what all of these ROMS/Kernels are doing are not allowing the phone to go into deep sleep...Not all the time...But they all experience the same thing eventually...They either get stuck and run at 1200 90% of the time or 1000...or they don't deep sleep like they should...When your phone sits on the counter for an hour it should register about 59+ mins of deep sleep...doesn't happen...Or it will work well for a day or 2 then crap out...Those of you getting terrible battery life...like losing 10% an hour while it sits unused, should install CPU spy and I can guarantee that is your issue...when your phone is off deep sleep should be your highest percentage used in CPU spy...

I think it has to be a kernel issue...Certainly not a ROM issue that's for sure...

In your battery stats it should almost never say that the Android OS is using 2x as much as your screen...I've seen this phone do 15 hours with 3+ hours of screen time, so I know good battery life is possible...but there's something going on here...

my 2 cents

[Samsung Epic 4G Touch] -EViL-KoNCEPTz-:
This is because there is a bug with the led notification that even when set to not blink the SoC polls the system trying to blink it keeping the CPU awake. If you use something like light flow or blink to disable it the SoC will go into deep sleep and the Android OS usage will drop to normal, and you will get normal battery life again. Its been discussed in almost every ICS and ICS battery thread at least once so idk why ppl haven't gotten the hint at where the problem lies yet ITS THE DAMN LED KEEPING THE SOC AWAKE DRAINING THE BATTERY! :banghead:

I installed Better Battery Stats and it shows that my phone is actually going into deep sleep (I am on a completely stock rom with the ICS update).

I don't know what happened. It is like once I removed that one game the update "took."

I should say that the day AFTER the update, I got a message on the phone that said it was "completing the Android Update", so I am wondering if there was something wrong with the update package and once it finally got completely onto the phone it worked.

Of course, I have no technical training at all, so I am really not sure. I am just happy the phone is working again and not simply dying like it was before.
[Samsung Epic 4G Touch] -EViL-KoNCEPTz-:
Did the "completing android update" message actually say "Android is upgrading" and occur after a reboot? If so that happens on ICS on a boot when the dalvik cache needs to be rebuilt, such as after wiping the cache and dalvik in recovery, or when an app wipes the dalvik or when you clear an apps cache in the app manager in settings, etc

[Samsung Epic 4G Touch] noobie100:
It said "completing Android update" or something like that. Come to think of it, I had gone into recovery and wiped the cache, so maybe that allowed the update to finalize or something.

---------- Post added at 11:38 AM ---------- Previous post was at 11:36 AM ----------

And, yes, if I remember correctly, it occurred after a reboot.
[Samsung Epic 4G Touch] -EViL-KoNCEPTz-:
It will do that every time caches are wiped, its the dalvik.cache being rebuilt its a new feature in ICS to optimize boot speeds. Go to recovery wipe cache and dalvik and reboot and see for yourself. After the boot animation b4 the OS loads a toast notification will pop up that says "Android is upgrading" with a busy icon spinning and "0 of XXX apps" XXX being the number of installed apps once the numbers match up the dalvik is rebuilt and the OS will load ;)

Hey, thanks for the response, I hadn't heard of this...

I installed both of them...Blink looks much less complex so I went through every tab (sms/mms , phone call, and system) and ensured that everything was unchecked = disable LED...and I rebooted...It's doing the same thing...It does go into deep sleep but if I leave the phone for untouched for an hour I'll get 40 mins at 200mhz and 20 mins in deep sleep...Other times, with the same setup it will immediately go into deep sleep and remain there...

thoughts?

Thanks again for the response.

I haven't used blink I use light flow with direct mode and accessibility enabled and my Android OS is at 17% right now it rarely gets over 20 or 25% its usually 11-20%, 17% seems pretty common when I check

Edit: I just checked it now, Android OS is 7% and android system is 12% screen is the highest @ 72% and every thing else is less than 7%

Let me translate what you are saying to make it an accurate statement...

"...bug with LED notification that has been mentioned in almost every ICS and ICS battery thread that I have read"

Much better, thanks. ;)

I've been all over this forum - even several threads of my own at the outset of that (you can see that this thread in particular, the OP mentions things specifically to drill into possible issues) as "almost every ICS and ICS battery thread" completely and totally exclude any sort of specific mention, instead leading me to paths that are general, cross-your-fingers paths without specific troubleshooting - like "how about wipe your phone and see?" It's frustrating to a systematic person like myself to take what are really pot shots that you cant' avoid at least trying as the lemming masses say "yeah, yeah, that should do it!" then - no result.

And think about that headbanging you are doing -

I'd be willing to bet nearly these "mentions" are just that - a blurt by someone in a four-word sentence containing the word "LED" in it.

In all seriousness, I'm going to use the information that you DID provide here as a lead, and do some searching for it - so thanks.

I'd just check that frustration at the door... look at the actual scope of this thread - diagnosis, specific symptoms. You want to talk about feeling like you are banging your head? Check the date of the OP. Read the six pages of this thread. Then see what you think.

Is there's an actual thread on this bug you mention, meaning one containing specific instructions or information on how to diagnose this, that would truly be helpful.

I'll at least check out what LiteFlow or Blink do, since you mentioned them. I haven't made any changes to my notifications from the former GB build, but I'm noticing sometimes my LED isn't blinking when it should, when I get texts, so maybe this is also a symptom of this bug you mention.

And thanks - this is at least new information, definitely a new lead, and does sound promising based on what you describe.
[Samsung Epic 4G Touch] geolemon:
Yep, I'm seeing this with my Nexus 7 also - Android OS is a small number.

Note I mentioned earlier, it's also a small number for my coworker's Galaxy SIII.

This is one of the reasons I believe it's an issue here.
