Yes sorry im thinking of something different Zeinzu but Still does use more RAM so no matter how flawless CM9 battery life your getting its better on CM7 and you know that.

But regardless something must be waking up your device for your battery to drain? i realized that i had to disable Beautiful widgets, changed some settings in other apps and now im doing fine.
[Epic 4G Android Development] Zeinzu:
Nevermind, retracting my statement just to keep the peace.

I have swype beta and the installer. I have had no issues, and did not have to reinstall or restore settings (which never seems to work anyway) when I flashed a4 over a3.

No Google Maps.

Doesn't install with GApps and cannot find it in the market.
[Epic 4G Android Development] bender beerman:
its under system settings>display> uncheck "pulse notification light"

because you didn't flash the gapps package.

edit: to be more concise, download and flash the "optional" gapps package from the cyanogenmod epic 4g blogspot page

Will nightlies be available on ROM Manager? If not where can they be found?
[Epic 4G Android Development] bender beerman:
try selecting system settings>security>lock screen> "improve face matching" and add several face captures with different lighting situations and distances from your face. also, with/without hat/glasses/earrings/facial hair. adding more pics will drastically improve face matching.

no, we'll

eventually

get weeklies instead of nightlies

was mentioned earlier in the thread that this would have weekly updates.

Anyone else having clock issues? The status bar clock sticks the time of my last reboot and the analog clock widget only changes the time when I kill trebuchet.

what games do you have working?

deadspace is not working properly ( due to the multitouch issue)

Street Fighter IV crashes when I start a match

MC3 still works (didnt play it for a long period to guarantee that)

blood and glory crashes

asphalt 6 crashes

nfl rivals is messed up and some other "Glu" game (the zombie game)

p.s. most of my favorite games don't work

I don't have the option for Facelock. Is it in the gsapps because that option is missing.
[Epic 4G Android Development] ÜBER™:
Yes its in the gapps

Thus why I stick to using emulators :D. N64 plays like a charm with the sixaxis control app :) I was very impressed that it ran as smooth as it did though there's a lot less ram compared to cm7 or TW.

Wow, wish every Alpha ran like this (not complaining of others work but damn this is nice). I've noticed no other bugs outside of what's listed (no surprise there), and this is just beautiful...you guys have given us a great ROM and I know we really appreciate ur efforts. Thx.

On a side note, the Black Exodus theme listed in Android Themes is great (flash through CWM) and I've noticed no ill effects after flashing. I'm on my phone so I'm not sure link will come through but here it is:

Is there a way to boost the 4G Signal??.. I notice I cant dial ##3282# to change the setting like I could before.. For some reason my signal bar is almost always stuck grey. When it usually showed almost full strength

Not sure if a setting issue or a EL30 modem issue..

Other then that.. Im loving this rom.. Havent had and FCs or reboots.. And all my apps run nice and smooth. Everything I use works to be my daily user rom =)
[Epic 4G Android Development] || Acer ||:
You can't use dialer codes on AOSP roms.

Anyway, back to my problem... I already tried to contact sprint about this to clear my voicemail inbox, but instead they got rid of my 3G, so I had to go back to a ei22 rom to reactivate my phone, only to learn that the voicemail never even disappeared even when I asked them to. So how would I go by blocking this stupid voicemail? Ik its small, but it is persistently annoying. I'd rather have it just not show then to actually be fixed at the moment, similar to just turning off voicemail notifications in CM7.

I know I already mentioned this not so long ago, but if anyone knows an easy fix PLEASE notify me ASAP.

I even unzipped the package, and there is no APK file for Maps in the package.
[Epic 4G Android Development] bender beerman:
well sorry then, i dunno. i d/l'd it the other day and it was there...

have you looked on the market on a computer and tried to install it from there?
[Epic 4G Android Development] brooksyx:
Google maps isnt in gapps you have to download it from the market.
[Epic 4G Android Development] LunaticWolf:
Why isn't it showing up in the market then?

Just a quick note to confim what others have said - scrolling homescreens appear to be ultra touchy. If I swipe all the way across the screen, the screens will rotate, but ever-so-lightly rub my thumb the opposite direction when I pull off the swipe, the homescreen zips back to page I am on.

This appears to not be kernel or V6 supercharger issue, because it has been this way from first boot after flash through install of new kernel and v6 script...

Not a huge deal, but noticeably different and a bit jarring.

Did you d/l the proper gapps? I got google maps just fine from the market after a fresh flash of a4 and gapps 20120215 or whatever the latest is
[Epic 4G Android Development] b16flybye:
Speaking of gapps, I'm not able to download it from the cm9 site. It directs me to google. I had to go back to cm7 for now. If anyone has the alpha 4 gapps you should shed a link pretty please.
[Epic 4G Android Development] anfrany:
That Google link sends you directly several sites to download gapps. Just pick the matching version 20120215 and verify the md5sum before you flash to be sure you got the right one.

I lost 32% battery overnight in 8 hours in airplane mode with wifi, gps and bt disabled. What is the media server drawing down on? It was 92% of my battery usage.

Thanks in advance for answers.
[Epic 4G Android Development] nimitz87:
I'm went from 75% to 29% doing nothing phone is deep sleeping 80% of 6 hours biggest culprit is mmc delayed work with 42min under kernel wake locks.

I know others who have had this problem but the culprit was apps on the sd card,i have none, any suggestions?

Thanks

[Epic 4G Android Development] XxLostSoulxX:
Whats funny is im on CM7 and this occurs i fixed some of the apps settings but i too have none installed on my SD Card. And MMC delay is weird one day its barely on the list then next day its at the top???

But i think my battery is regaining again yesterday my phone was @1% at 1:00am and when i got up around 6am i checked phone because i thought i had it in the charger but wasn't connected and still was at 1%.
[Epic 4G Android Development] xshawk:
Similar issue here, currently 3h 44m 41s on Battery (fully charged at 5am) at 33% now. Mediaserver was accounting for 40% an hour ago, now it's dropped back to 22%, Android OS is 29%, and Screen is 30%... regardless the battery life is abysmal at best.

I'm going to see how long a full discharge takes (in case the indicated level is off)

then switch to my backup battery and post the results.

[Epic 4G Android Development] awoolf:
This is my biggest concern. Are there any third-party utils to allow permission blocking / management in CM9/ICS? I won't be using ICS as a daily driver until this is available.

My second biggest concern is the Google-account-auto-login in the browser. (I have multiple gmail accounts that I DON'T want linked together or automatically logged in.) A number of searched have led me to believe this can't be disabled, and I'm not happy with any of the third-party browsers I've tried so far.
[Epic 4G Android Development] raineyland:
Yeah, I just thought I could get an idea of how low I can go, lol. Ty.
[Epic 4G Android Development] ashbuly:
Depends on the kernel you are using, but in general, you can OC to about 1500 MHz and UV from about -50 from 1500-1100, and then increase up to about -150 at 100MHz.
[Epic 4G Android Development] kobby2k6:
"autostarts" helps but can only stop a few apps from starting up, permission management is more extensive and the reason I loved cm7...I am addicted to cm9 at the moment and I hope more ram gets freed and permission management gets implemented in the future....some apps start up anyway though...i think it has to be updated upstream though...
[Epic 4G Android Development] lmsomb:
Agree that battery life is minimum with ics rom
[Epic 4G Android Development] aestil:
Beautiful ROM, performs not too bad either, battery life makes using this impossible for me. losing 50%+ over 3 hours of phone just sitting doing nothing.

Thank you for the ROM, I'm sure the battery life is one of the highest priority things you've got going.

I'ma restore CM7 which is rock solid, fast and amazing battery life, and keep watching the development of this ROM. I'm sure I'll flash the next alpha to test it as well. :D
[Epic 4G Android Development] Blad3:
you guys should refer to my earlier posting in this thread about mediaserver. no help though on what to do about it.
[Epic 4G Android Development] xshawk:
Annnd it froze

here's screenshots of shortly before and right after my phone locked up on me.

roughly speaking that's 4hr's of battery life from fully charged to less than 10%.

not sure what caused the lockup... and as I plugged in to transfer screenshots, time to "death" is no longer accurate. but I'm going to let it die once anyway.

I feel like an imbecile here, but can anyone tell me where to get the history page I keep seeing in screencaps? .... Never mind...

for anyone else confused it's "behind" the battery graph.

(I just hadn't tried tapping on that one yet)
[Epic 4G Android Development] RealTic:
Battery life is not that bad actually..... i would suggest finding whats eating up your battery. Some phones have had trouble going into deep sleep, sounds like this might be what your experiencing. It's only Alpha 4, less than perfect battery life is pretty acceptable by my standards, especially with how well this rom performs at its early stages.

P.S.-----> Although it is NOT advised going outside the standard issued kernel, try using the ShadowKernel. I have been getting very decent battery life with it.
[Epic 4G Android Development] Speedin07si:
No problems with my battery life.

Stock battery, CM9 kernel, no themes or tweaks. Two email accounts set to check every 15 min. Brightness set to automatic.

Yes my screen on time is just about 1 hour. People having battery life issues need to figure out what app is causing them. It's not solely a rom issue.

[Epic 4G Android Development] Shinydude100:
I think its worth noting, I use to get 10 hours on stock and around December 2011, it dropped to 6 hours, by new years, I was switching phone companies and my Epic's stock battery was lasting 30 mins. It then got to the point where in less than an hour, it charged from 0% to 100% (with phone off) I then bought the epic touch battery off amazon. I still get battery drain because of bad signal at home but I can proudly say that with medium use, it lasts a good 8 hours, light use, it'll last all day, and heavy use, about 4-5 hours.

[Epic 4G Android Development] styles420:
Let's try correcting the misunderstanding again... the one and only issue with using custom kernels is that any bugs you experience could be caused by that kernel, and therefore you would need to report your bugs in the custom kernel's thread. If the bug is not due to the kernel, then you don't need to worry about your bug report being in the wrong place because someone else will definitely see the bug with the stock kernel. (No they won't, you say? If not, then the problem absolutely does not exist in the stock package, which leaves the custom kernel as the only possibility... unless you flash a half-dozen other mods at the same time, but then I wish you luck finding your needle in that haystack...)

That is the only "problem" with using a custom kernel - feel free to use any kernel, just don't report bugs in the main thread if you do.

In other words, no one has advised against custom kernels - Deca just doesn't want misunderstandings where a bunch of noobs freak out because they don't realize that they don't know what they think they know - people who are so easily convinced by false information (because they don't know the difference) are much harder to enlighten with the truth (because... they don't know the difference...) :)
[Epic 4G Android Development] TPMJB:
I don't know if this is just coincidental, but I think I had more battery life on Alpha3.
[Epic 4G Android Development] aestil:
Bottom line: I have apps installed on CM9 that I have installed on CM7. I didn't try to back data up, or restore data. I just d/led the apps and installed them from the market. *IF* one of those apps is causing a problem on CM9, or if CM9 has some inefficiency that is causing me to have the unusually high battery drain I'm going back to CM7.

Those apps I install are apps I need/want. if they cause a problem on CM9 then I have to roll back to CM7 so I can use them without having absurd battery drain.
[Epic 4G Android Development] xshawk:
still going

I must say that ICS has really grown on me Many thanks to the CM crew!!

this ROM has made me like my phone more than anything I've done yet.

heck Sprint should thank you too!

back to the Battery issue I think I've figured out my malfunction.

interestingly enough my battery drain has backed wayyy off... I've been running for a couple hours at less than 10%... this may be a combination of (at least) 2 factors...

1) I did finally get the LED to stop blinking around the time I hit 6% battery(the first time I disabled it it didn't take)

2) the calculated battery level may still be lower than actual (I only flashed to A4 yesterday)

as the LED fix was posted quite a ways back I can't see this as a major issue.

(I just didn't get the fix implemented correctly the first time)

I will see how long I can make this battery hang in there before charging.
[Epic 4G Android Development] Zeinzu:
Well my overnight drain seems to have stopped after clearing and reflashing the ROM once more. Did a test with wifi on, overnight, ten hours. Deep sleep of 98%, still says it woke a number of times, but only drained 7-8% in 10hrs. BBS didn't show anything out of the ordinary, batterystats under settings showed wifi as the biggest user of battery (which would make perfect sense), and this seems plenty adequate for my tastes. Battery life throughout the day still seems plenty fine as well. Tonight will be testing wifi off.
[Epic 4G Android Development] Devtodi:
Did you wipe data when you related? Did you reflash gapps or gps fix again? Do you have Dropbox installed?
[Epic 4G Android Development] ippikiokami:
For alpha 4 other than gapps does anything else need to be flashed?

[Epic 4G Android Development] Xinlitik:
I'm getting fine battery life with alpha 4. It's not quite as good as CM7 levels, but from what I hear that's just an ICS problem, not a CM9 problem. And ICS features are WELLLLLL worth it.
[Epic 4G Android Development] StoneRyno:
I don't have this problem with google maps but I do have that problem with bejeweled 2. It is the only app that says not compatible with my device. However this was not a problem on alpha1 but has been a problem on alpha2, 3, and now 4. I assumed it was an update EA did until I checked today to see thei last update was older than my install date of alpha1.

My guess a corrupt media file or something got media server stuck in a loop. Or something related to it got stuck and caused it to run needlessly.

Battery drain this bad on any ROM (stock or custom) is an indicator that something is misbehaving. There are a number of tools built in and downoadable that would help to identify what is causing the drain. It would be a good idea to find out as it not only would help you but may help others who are also wanting to know why their battery is draining abnormally fast. I'm assuming that previous posters about this sort o thing have or plan to use those tools to figure out the cause.
[Epic 4G Android Development] vita10gy:
When I first flashed alpha4 I noticed battery so terrible I could practically watch it drain. Haven't cared to look much since then. (I don't have many occasions to wander far from power.)

Battery is a YMMV situation, but I think it's safe to say there's some problem alpha4 introduced/exacerbated re:Media server. However, you don't have to jump ship altogether. Why not see how alpha3 works for you?

The "big" problem isn't CM9, it's alpha4.

I think it's fair to point out that many phone's "alpha4" means "The phone technically turns on and as long as you don't care that the touchscreen, buttons, calls, data/wifi, bluetooth, or audio don't work, you're all set to flash."

Worst case scenario a4 was one step forward, two steps back. Try a3 (or anything) before you declare the whole endeavor not fit for daily consumption yet.
[Epic 4G Android Development] XxLostSoulxX:
Is it as good as CM7? No haha The point is using a stock battery your phone is only lasting as long as it would stock. 6 hours is horrible. I currently am at 18 Hours with 2 hours screen on time and WiFi on for about 5 Hours straight streaming music on CM7. People usually tend to use their actual phone. I'm getting more battery one because I'm using a 3500 but still you get the idea.
[Epic 4G Android Development] aestil:
I had better battery stats, nothing was causing the battery drain as far as I could tell. In any case, I'm glad that the battery life 'isn't that bad' for some of you. Although I don't understand why reporting on my experiences has caused some of you to be so defensive. I'm not trying to kick your puppy.

[Epic 4G Android Development] charliet1010:
Ive been using this rom for about a week now, switching from stock 2.3.7, as far as battery life I have not seen any real difference, but as for performance it has greatly increased! ICS is the greatest improvement to android I have seem so far, and I had the original Motorola Cliq with 1.5, got 1.6 and beta tested 2.1. ICS revitalized my "old" phone and put it ahead of the curve.

Same here, 12 hours using phone with 2 email accounts several texts and still at 44%. Really about the same as what I got on stock.

I'm having the same problem. Try disabling the notification LED and see if that helps. Since doing that my MMC lock time has decreased greatly. Very light use in the last day - 1d1h of battery time and only 40 minutes of MMC lock.

I have Googled the ever-loving crap out of the MMC thing and there does not seem to be any explanation available.

Bottom line is that disabling the LED has transformed my battery life.

[Epic 4G Android Development] ashbuly:
ROM toolbox will allow you to fix your auto start ups. After going to the start up option, slide to the next screen and commence disabling the start options such turn app on when plugged in, start when date changes, etc...makes a HUGE difference on battery life.

Not sure if this can be done on the free version or not but I reccomend buying it anyway. Best $6 I've spent.
