I am glad I am not the only ones with these problems.

It has to be a ICS function that is causing the excessive battery drain.

I currently have no non stock apps installed.

I have noticed that the battery ran from 100% to 25% but battery drain had no slowed considerably....maybe faulty logic in how they are calculating percentages?

The one I would really like to solve is the buttons not working, as there will be lots of battery related threads as more and more people upgrade.
[Samsung Epic 4G Touch] Dalmus:
The malfunctioning buttons have been happening to some of us on every ROM, whether it's Gingerbread or ICS. It happens to mine on stock GB or stock I'VE.

Just so you know, you can tap the volume Roche to wake up the buttons. You don't have to cycle the screen. Tap the volume button, wait second or so and you will see the capacitive buttons blink once... That means they've reset. Sometimes you have to do it twice.

I went back to the tried and true Blazer 4.1 Nothing comes close....

Do you have wifi turned on? Others have reported Wifi is constantly scanning.
[Samsung Epic 4G Touch] elliwigy:
never had those issues.. but i never updated with ota.. i used sfhub ff18 one click :-)my physical buttons always worked from gb all the way from first ics leaks to now
[Samsung Epic 4G Touch] ydoucare:
Same issue here with the retarded battery life, stock rooted FF18. It's pathetic. Constant battery drain while "sleeping", with wifi on or off. Guess i'll have to try a different ROM.
[Samsung Epic 4G Touch] cas8180:
Actually rule a ton of people are reporting these exact same issues in the sprint community running factory ics update. So these issues are pretty common. I am also experiencing quite a few myself.
[Samsung Epic 4G Touch] cas8180:
This is the first time I have ever seen this mentioned for ics. Do you by chance have any other links confirming that this works? I am very skeptical about this and sounds more of a voodoo type of fix..

it works. ;P

also i only meant do it a couple of times if you messed it up lol.

seriously, guys on ics, try the fix!

works for me on gingerbread. and also on ics.

"#1 TURN OFF YOUR PHONE and charge your phone until u see and blue light & 100% sign on your screen(while the phone is﻿ still off) #2 remove battery & then unplug charger. LEAVE BATTERY OUT FOR 5 FULL MINUTES. #3 put battery back in . Let me know if that works(it should)"

[Samsung Epic 4G Touch] DirkBelig:
I tried this yesterday when I was getting terrible battery life. I went from fully charged to dead in 3 hours flat.

I ended up doing a factory reset with sfhub's one-click and am slowly testing and restoring apps to see what's acting as a vampire.
[Samsung Epic 4G Touch] ebuc:
You should try it again if it didn't work!
[Samsung Epic 4G Touch] scarmon25:
Not everyone's issue is going to be caused by the same thing. What may work for you may not always work for everyone else. It may be an app or ICS in general causing the issue.

Need Help find us on our IRC #Team Rejects or

Everyone needs to pile up in the sprint stores in front of potential new customers and demand a fix.

[Samsung Epic 4G Touch] ebuc:
actually getting a local news station involved and claiming a conspiracy theory of some sort claiming the update made your phone worthless would yield better results lol. just saying.

lol my update is downloading. i might just be with you if you feel like causing some trouble for sprint >:D

@scarmon, i know but this works so well for me :/

also, galaxy nexus instead of s3's!
[Samsung Epic 4G Touch] cpcormier3:
Yeah this update sucks. The battery life is about half what I used to have. The wifi is a joke now. Doesn't stay connected. The phone gets pretty hot when I'm just reading on it.
[Samsung Epic 4G Touch] nonstop14:
Posted a similar thread early yesterday and it was moved to Q&A and subsequently buried.

"Two Epic Touch's in this house. After official ICS update both have had a dramatic decrease in battery life. They last approximately 2/3 to 1/2 as long as they used to under similar usage scenarios. WIFI has also gone from rock solid in GB to constant disconnects."
[Samsung Epic 4G Touch] delfin2003:
Confirming two issues on my phone:

1. Wifi disconnects sometimes.

2. Battery life is about half of what it used to be on gingerbread.

Btw, never did root or did anything non-stock to my phone.
[Samsung Epic 4G Touch] tonyman121:
Agghhh what a friggin' headache. I updated yesterday....

1. WiFi cannot stay connected for more than a few minutes

2. Battery is dead after 8 hrs with the phone not at all in use (using juicedefender at balanced)- previously was more than 24 hrs with heavy use

3. Swype doesn't work- couldn;t even unlock my phone since it fails to load and no keyboard comes up!

fully charged this AM, had only 62% battery remaining at 8AM. Listened to 2 songs on google MP3 player- 58% when the second song ended.

Ouch
[Samsung Epic 4G Touch] pjkingphd:
Could you provide a link to the ROM you're referring to? Thanks.
[Samsung Epic 4G Touch] cas8180:
Yes I can read instructions can you? You didn't answer my question
[Samsung Epic 4G Touch] sling:
yeah Ive had enough ics ET4G junk build.

I will stick with blazer GB 4.1 until I pic up nexus this winter
[Samsung Epic 4G Touch] cas8180:
Hey guys I started a thread on sprint's community site I am trying to get more people to speak up and I am also reaching out to sprint directly and referencing this thread as proof of the issue. Please report your issue's here:

http://community.sprint.com/baw/thread/94157?tstart=0
[Samsung Epic 4G Touch] tonyman121:
Oh yeah, one other WEIRD issue.....

In the past year or so, I had a number of occasions where I sent an email from my phone, but the recipient never got it. Well, when the ICS install finished, all these random emails went out. I got a lot of strange emails after than asking WTF I was talking about... or picture mails from 6+ months ago where the attachments were farked.

Weird.
[Samsung Epic 4G Touch] adbrown83:
Swype fix has been found...it is in the official update thread.

Settings-->Applications --> All ---> Swype

Press Clear Data

You will lose your dictionary but Swype will work again
[Samsung Epic 4G Touch] tonyman121:
That fix didn't work for me. I was using the stock Swype with GB. Looks like the program was erased, as there was no "swype" in the applications tab.

I went to the Swype web site to download the beta version. We'll see if this works.
[Samsung Epic 4G Touch] dan02gt:
I had the same issues with the FF18 based Blazer 0.1.3 and I was hoping that FF18 would not be the final release but they released the turd. I went back to CalKulin's EL29 ROM and froze the Update service. No way I'm putting ICS on my phone till they get it fixed.
[Samsung Epic 4G Touch] kingsway8605:
A battery pull after charging was a confirmed fix for the Android os bug that has plagued Android for several versions. If the Android os bug is the source of your battery life woes, this will help. But in general the current ics builds just seem to be more taxing on battery. It is all that pretty eye candy.
[Samsung Epic 4G Touch] tonyman121:
I tried the battery pull- didn't do diddly poo.
[Samsung Epic 4G Touch] krisI0N:
Yeah I'm having a lot of these e problems using the stock ota and I even had a problem where it sounded like my speakers were blown, I had to restart the phone to fix it. Kinda worries me.
[Samsung Epic 4G Touch] ebuc:
@cas http://xdaforums.com/showpost.php?p=28832191&postcount=375

???? helped him out a bit anyways.

Also, the ota ics update isn't as bad as people are saying it is.

Sub-par battery life, fast scrolling, wifi seems to disconnect/sleep randomly ,ics seems to take a larger toll on the ram for some reason, and that graphical bug at the multitasking screen are the only known bugs i've seen

Its usable, nothing much to really complain about.
[Samsung Epic 4G Touch] tonyman121:
Also, the battery has no problems when WiFi and 4G are off- clearly that's where the problem lies.
[Samsung Epic 4G Touch] krisI0N:
Well, like gingerbread it'll improve in time hopefully
[Samsung Epic 4G Touch] Ravaged Pheonix:
I just find it hilarious that there were very few *****es about the ff18 leak,and everyone was stick and tired of waiting for the update. But now that its an OTA we have to listen to all this righteous indignation about how no one ever wanted ICS, how much it sucks, and we all should go riot in Dan Hess's living room until we get what we want. You are *****ing on XDA for Christ's sake. Shut up, root your phone, and install a custom ROM. Sorry if I offend you, but this is getting ridiculous.
[Samsung Epic 4G Touch] kingsway8605:
There are only four actual roms for this service, aosp, aokp, miui, and Samsung. All others are just themed and scripted variants of the four. Sadly, Samsung seems to have the longest battery life, and it isn't long enough. Can't speak for others, but I have always said ff18 wasn't ready. Sprint and Samsung dropped the ball on this one.
[Samsung Epic 4G Touch] adbrown83:
Had an interesting time since my original post in this thread.

I went into Sprint ID and changed my theme. Getting rid of TouchWiz has really seemed to help.

My battery is still acting incredibly funny but battery life with no TouchWiz seems to be a lot better.

I put it to sleep with 25% last night and woke up this morning with 28% remaining. So in about 7.5 hours I gained 3% on my battery.
[Samsung Epic 4G Touch] RoysInDaHouse:
I'm getting 4 hours of battery life now. I was getting 2 days of battery life.

I filled a BBB complaint. Not sure if it will help but maybe if everyone did, sprint might get the idea that something is wrong.

Phone went from working perfectly to being a POS in a matter of minutes via a update.
[Samsung Epic 4G Touch] PhAkEer:
Three main contributions to these issues...

Most likely, too many proccess' runnin at once.. In which, android is prioritizing appropriately per its instructions,

That explanation would be consistent with your battery drain. As stated, wifi and the wimax are big contributors... they directly tie into the power supply and if left unchecked, youll have thirty apps all stealing your information to sell to advertiser at once.

Keyboard is not a high priority compared to staying on.

2) unclean install/broken systemUI... This also has been covered.. Fully back your must keeps, wipe everything, and do a fulk factory restore...

3) A little of #1 mixed with a lack of functional literacy among other user errors...

These "issues" are talked about again and again but nobody ever listens to those who have been testing these builds for months... You didnt buy a phone, you bought a computer.

Reboot it every now and then, regulate what runs at boot, disable your god forsaken social networks synching, set its priorities around how youkk be using it..... and if yiu are still having issues, we have somethibg to talk about.

Im honestly not being rude...

But man, i would have had (can still ;) ) your phones fixed before you even noticed an issue =)

Oh, and nonresponsive capacitive buttons is typically a hung task (supporting two and three... And one....) So try a permission fix and pray.

(and you can thank Mary for the typos)
[Samsung Epic 4G Touch] delfin2003:
75% battery at 11:00pm

39% battery at 7:20am

Never rooted my phone ever, did a manual ICS install via stock recovery and a full system wipe clear cache from stock recovery as well. WTF is going on?!
[Samsung Epic 4G Touch] rj1st:
Google Maps Issue?

I'm not sure if this is everyones issue, but Google Maps was/is KILLING my battery with ICS. Here is my experience.

I charged my battery 100% yesterday, took if off the charger around 7am, by 7pm I was down to 15%. With almost no usage. ( I made a 30 sec phone call, and sent maybe 15 txts.) I checked my battery stats and google maps had woke my phone up over 200 times in 12 hours. That seemed a bit excessive to me.

So I charged my phone up again, but forced stopped Google Maps before I left. My battery is now at 90% (in 4 hours 5 mins). With minimal usage.

I should also note: I did the update via stock recovery, and then a full factory reset. My phone is stock, and before ICS I was getting around 24hrs average battery life for weeks.
[Samsung Epic 4G Touch] bmacuc:
Same boat as you. On stock, unrooted GB, I would average about 8% battery discharge overnight while sleeping (7 hours sleep average). On ICS I am anywhere from 30-50% discharge overnight.
[Samsung Epic 4G Touch] badkarmah187:
going back to GB

OK, 3rd day on ICS stock. I had AGAT 0.2.1 kernel and yesterday installed CWM so I can make a nandriod backup. Battery performance was ok for the 1st two days, than inexplicably goes from 75% to 20% after a reboot. This had happened to the other 2 ICS FF18 roms that I have tried this month.

Going back to my Calkulin 3.0 GB rom nandriod for now.
[Samsung Epic 4G Touch] robcy:
the WIFI did it

I have had FF18 since June 20th, and this is what I have learned. With Wifi on, my phones consumes 8% of the battery per hour while its sitting face down on my desk. With Wifi off, my phone consumes 3% of the battery per hour while sitting face down. A co-worker has the same phone but he is running FF11, and his figures are exactly the opposite of mine. Both phones with the 4G on use 4% per hour sitting face down (not used). I have not experienced a single issue with FF18 from a stability standpoint, and the GPS locks have never been faster. If I do not connect to Wifi my phone will last all day. So basically my phone has 4G turned on always,
[Samsung Epic 4G Touch] badkarmah187:
I'll try the wifi thing next week.

thanks for this info. I'm going to take a few days off for vacation and need a stable rom with long battery life. restoring GB until next week.
[Samsung Epic 4G Touch] liquefiedvapor:
Sorry for the noob question, but I've been trying to track down my battery drain as well (mine's been about cut in half), but could you please clarify (or if someone can) how you can view that google maps woke up your phone 200 times? Do you have to be rooted for that? Thanks in advance!
[Samsung Epic 4G Touch] tonyman121:
I just think it's not that simple- we're not all illiterate dopes. I turned off all applications (and don't generally have any crap on my system), turn off all sync permissions except microsoft exchange set to 1/hr on peak times. I recalibrated the battery. I noted as others that WiFi alone uses up 10% of the battery/hr. Turning off WiFi and turning on 4G significantly improved battery life (to less than 5%/hr). Both are with the phone running no servies other than Watchdog and Juicedefender in the background and basically not in use. Yes, the obvious next step is to do a factory reset and start over, but it's a pain in the ass to drop everything and back up your phone. I'm in the process of doing it, and hopefully the battery issue, as well as NOT having 3G service or swype will improve. But really, it should not have to come to this. Honestly, I never rooted this phone or added ROMs because the phone functioned so well natively (as opposed to my previous HTC touch), but now it looks like I'll probably have to go that route.
[Samsung Epic 4G Touch] rj1st:
I have an app called "GSam Battery Monitor", and from the main screen you can click on "App Usage", and then change "View % Power Used" to "View Num Times Waking Device" there it'll show you what apps have been waking your phone. Best of luck.
[Samsung Epic 4G Touch] meltmanti:
That's because the FF18 leak was just that - A LEAK. We expected them to resolve the issues before going OTA with it.

I had the battery issues with the leak (obviously) and still do. I didn't complain then because it didn't seem finalized.

:eek:
[Samsung Epic 4G Touch] tt281gt:
Have you guys tried doing a full wipe/clean install?

I have been running ICS "leaks" for months now including FF18 and I have none of these issues. The battery does not last all day but I keep 4g on most of the day and use the phone quite often. If I don't touch the phone [impossible] it will for sure last at least a full 24 hours [probably more but never tested can't keep my hands off my toys].

I always do clean installs/full wipe and delete any bloat/apps/widgets I do not use using root explorer.

I also move the following google apk's that seem to run for no reason into a "revomed app" folder in my sdcard:

-Bluetoothmap.apk/.odex

-Bluetoothtest.apk/.odex

-Googlepartnersetup.apk/.odex

-Sprintandroidextension.apk/.odex

I have noticed NO bad effects by moving those out of the system/app folder and into the folder in my sdcard and if I ever needed them I can move them back.
[Samsung Epic 4G Touch] tonyman121:
It took a while, but I did a "full wipe" and then a clean install. It did fix a lot of the issues I had- specifically Swype and the lack of 3G service. I also noticed a big difference in download speeds with 4g. The battery issue remains though.

One possibility (other than a bad install or conflicts with the previous OS) was that I was running juicedefender and watchdog, and juicedefender was thought to cause problems with 4g. In the new install I only reinstalled apps I needed (Netflix, TuneIn pro, unified remote, Speedtest, and alarmclock plus).
[Samsung Epic 4G Touch] yellowman82:
It fixes some things but still lack, I prefer to have this kind of battery and smoothness over new kool features
[Samsung Epic 4G Touch] ebuc:
Not bad for stand by time/minimal use. considering some peope were saying they were losing battery life doing nothing.

Ota stock, with battery fix helped me out. Ota isn't that bad for me lol, just a few bugs.
[Samsung Epic 4G Touch] tt281gt:
Understood, in my case I love all the cool features and I have a charger at home, work, and in the car [I also carry my home charger if traveling so i can plug in at a friends house if needed] so I never worry about a dead phone.
[Samsung Epic 4G Touch] dz1:
ok im not a flashoholic or the most well informed about the epic 4g touch but i have to agree with you guys battery life sux. I have no problems with wifi 3g messaging ect. but i was in stock official el29 and had pretty dam good battery life no tweaks nothing fancy just stock. I upgraded to ics clean intall no problems little glich on buttons not responding for a second or two but only happens 1 or 2 a day so no complains. But no matter what i do battery drains fast i have removed most auto sync apps unistalled facebook maps ect. Honestly i dont know what to do :crying:
[Samsung Epic 4G Touch] cas8180:
See this post here http://community.sprint.com/baw/thread/94157?tstart=0 and call the number listed and complain. We get enough of them and sprint will have to take action. I already got a phone call back today....
[Samsung Epic 4G Touch] cp320703:
90% of this thread belongs on sprintusers or sprints official forum... your dissatisfaction with the OTA has nothing to do with custom roms. These threads are annoying as there are 10's of them daily all about the same things which would be less of an issue if you would follow the advice given by more knowledgeable members around here, i love how rujelus22's suggestions on the first page of this thread were instantly disregarded despite the fact he developed one of the best rom's for our phone (blu kuban) which, incidentally, has exactly NONE of the issues complained about in this thread and full day plus battery life, or what about mijjahz's goodness, which is also extremely stable, pretty much bug free, and rock solid day to day, also with great battery life. These are based FF18, so if rujelus22 is saying these problems are not from FF18, i'm inclined to believe him, as who would know the build better??? Have any/all of you tried a data wipe or is this based off of a no data install? have you re-calibrated your batteries after the flash? installed better battery stats to see exactly what is draining your power? There are any number of suggestions out there, many of which have ALREADY BEEN ADDRESSED back when FF18 first leaked. That said no one here is going to patch the OTA for you, if you want to complain to sprint, complain to sprint, but don't clutter up XDA with gripes about an OTA. Why not flash one of the aforementioned roms if you don't think AOSP builds are solid yet (they are, though) or otherwise get off the OTA, the only reason we're here in the first place is to IMPROVE and REPLACE stock software, not to complain about how we weren't given the worlds greatest phone operating system over the air by sprint... in short this is NOT THE PLACE to whine about the OTA... if you don't like it, FLASH SOMETHING ELSE, we have tons of fantastic roms that are very dependable for day to day use and tons of patches/mods to fix/change anything you may want to. If you don't know how to flash to something else READ! don't post, everything has been answered already around here, if you don't want to flash then what are you doing here in the first place???? go to sprintusers or sprint forums, XDA is not the place for you.... sorry for coming across as a jerk but I've been avoiding XDA for the past two weeks because I'm tired of seeing the same things over and over and over again, burying and otherwise obscuring any interesting threads or people with ACTUAL, NON OTA-related issues.... garwynn started a thread a day or two before the OTA was pushed for all the crap like this, why do people INSIST on starting thread after thread after thread of the same thing in lieu of just reading the OFFICIAL OTA THREAD and posting there, where it belongs??? /sage/
[Samsung Epic 4G Touch] Ravaged Pheonix:
Glad I'm not the only one cp. This is a development website. Its in the friggin name. This is not sprint tech support. If you want to install a custom ROM we will be more than willing to help with the stated issues. If you are unwilling to modify your phone, take your problems to sprints website. The custom roms here will address any issues that have been listed here. If you want to gripe about stock, take it to the forum of the developers of that software, SPRINT! You are just spinning wheels here. No one on this site is going to push a fixed OTA to your phone. Again, if you are willing to mod your phone, I will be more than happy to assist you.

[Samsung Epic 4G Touch] Jamin13:
I like this thread. It explains things that can be fixed with development. Besides, this is the general section. Anything pertaining to something general about the Epic 4G Touch can be started here.
