Phone does not wake up after ICS

Hey everyone,
I flashed ICS a few days ago and then a day or two later flashed rocket rom. I am not really sure if this problem happened before rocket or not.
My phone randomly "shuts off". Maybe it doesn't wake up, I don't know how to tell the difference. I have to either pull out the battery or do a hard reset sometimes.
Any suggestions as to what I should do? Go back to gingerbread? Or reinstall rocket? flash a different ROM (midnote, etc)?
Thanks everyone!

There is an app called Wake Lock or Keep Awake or something that won't let your phone get into deep sleep so it doesn't happen.

Had the same problem, I remembered from the HTC HD2 forums something about avoiding it by turning off auto-brightness.
After having 4 sleep of deaths in 3 hours, I had it once in 24 hours. Dunno if that's what affected it, but much better. Try it.

Kernel related. Flash a different one. Wipe cache and dalvik after kernel flash.
Some kernels are plagued by this problem because of kernel base used. Minor hardware changes in newer batches do not like the old kernel base.

[Q] Battery life - my sisters I9000

Guys, my sister has had her I9000 for a good few months now and everything was fine until recently.
She phoned me (knowing I like my phones) saying her battery life had become really poor over a couple days.
So I took the phone off her and updated it with Kies, so now it's running the latest Kies Gingerbread for that phone. I should point out it is not rooted, completely stock.
I noticed some crummy looking app's like Android Anti-Virus and Task Killer so removed them hoping one of them was acting the goat.......everything seemed to be going good until yesterday and she charged the phone all night until 8am and when it came to around 2pm the phone was flashing up with low battery alert. She said she had used twitter a little and browsed on the internet a while.
I have told her to get CPU Spy and look if the phone is going into deep sleep, yesterday it had 0% deep sleep and today it is saying 70% deep sleep even though the battery only lasted 6 hours before low battery warning...
Any ideas what I can do to track down where the problem is? Would she see better battery with ICS or a custom GB ROM?

Mine did this on stock ROM luckily mine lagged when I went into battery use it was Samsung app push update service or something like that but thanks to the lag it showed sleep lock before it shower that service I uninstalled then it could go back into deep sleep

Can I uninstall the Samsung app without root?

Yes if its the one I think it is, could you post a screen shot of the battery usage up? Just to be sure?

Try to flash speed mod kernel on your sister device using Odin

it will root your device and install clockwork mod, should fix the battery issues though. Try flashing the CF root kernel via odin. Theres a tutorial in the thread.

After the odin flash, you can use titanium app for remove apps or system apps unnecessary

Is samsung gonna fix the bug on 4.0.4 or what?

Hi fellas,
Im just wondering is there any fix on 4.0.4?
I mean the battery issues and overheated device? Cuz im thinking of rooting my device in the end to just giving it a try. But it will void the warrany for sure. So, just wanna know if any of ya all just happen to know if thers any fix coming out real soon. So that i can wait.
It seems that my device is now consider as useless piece of s...t just wondering why would i want to use this so called smartphone if i cant use live wallpaper, push email, screen brightness for my luvly super amoled screen and so on if it drains the battery like thirsty camel. It just a thought tho.... U guy might be thinking the same. So, i did all the the things like calibrating the batt, installed cpuspy, take out the batt on plane mode trick and so on.. , yes it did help the device to sleep. But it drains when im using it for 3 hrs with a lil bit of surfing, emails and sketching .it just doesnt make any sense at all.
Dont you guy think that samsung is trying to lure us to change to s3? Or note 2? Well it did cross my mind. Lol. i might not consider samsung in the near future. I guess,htc x one is my choice cuz it offers 6hrs batt. Hehehe

dude battery life with screen on in clean condition, without fancy stuff is only 3.5 hours. Some with other kernels/roms have reported 4 or even 5 hours, but that's really max

It is a power hungry phone,
Large screen - If you've got your brightness all the way up will use more power
Live Wallpaper - Pretty - Battery drainer
Games - Power hungry
etc
As mentioned - you cannot expect to use a phone like this for 8/9/10 hours with constant use, At 3 hours constant use, screen on, probs wi-fi / data, Gaming, listening to music.. you will see the battery drain quicker..
Could alsways pick up a one of those larger Mugen Power Batteries / second stock battery if your usage demands it... I've got two stock batteries but the actual amount of times I've need to call on the backup one is rare, I keep it handy as both me and my girlfriend have GNote's.

Thx for replying guys,
Maybe i left something earlier on. 3 hrs of moderate usage..as in moderate guys. Ddnt hppn to me on gb. I had at least 5 hrs max on gb without turning off thos fancy stuffs.Thats the main issue. So ics is the culprit.

Have you used BetterBatteryStats to see what's happening in the background? Maybe you've a rogue app installed....

Well then there are ways to analyse, as posted above for abnomal battery drain in deepsleep, when not using phone. That is one option.
Best guess is to do a full clean install of 404 by going to gb through pc odin, root it, get on cwm recovery, wipe cache, dalvik cache, backup efs, save pictures on computer, backup messages with app from play, sync contacts to gmail and then backbin recovery format everything in mounts, except efs,ofcourse.
Then phone wont boot, but is truly squicky clean. Then go into download mode and flash throught oc odin a stock 404 rom.
Do not recover apps/data, just manually redownload them.
Dont ever on unsafe kernel from stock ics do these steps. EVER!
Then download cwm. zip which is temp and flash speedmod k3-11 from recovery. I bet your battery life will improve and you will get 4 hours screen on time. Not as good as on gb,but still better then now
there are threads for every single step here, start in dr ketans thread in sticky section of development. Then tool thread of dr ketan in general section.

Thanks bazz,
Haha its me again complaining bout the batt in
Here. Well i did all the tricks from the past thread. Well it worked as in the device went to sleep like a baby. But when i wakes up, only god knows. But yeah, thnx for the info again, but thats the problem bazz, i just need to know bout the fix. Tried to call samsung support but they are not too sure bout it. Cuz im willing to wait for the fix but not too long. Currently i hv dis dilemma of maybe selling the phone with stock rom, and buy another phone
or rooting this phone which im not too sure how to go about.

Use the BetterBatteryStats to see what`s going on behind and CPU spy to see what is the Mhz you Note is at.
On 4.0.3 ICS I find my battery lasts longer than on GB.. Strange!

i dont have problems on 4.0.4 with draining or heating...
maybe there is some app .... e-mail push 5 min......

Same here. GNote with ICS 4.0.3 has a worse battery life compared to GB, not to mentioned occasional freeze and unresponsive screen, also broken wifi-direct. Pretty disappointed with Samsung in the software department. Jelly Bean was already out and OTA for ICS 4.0.4 for both my GNote and GTab 7.7 not yet available in my country. Come on Samsung, these products is a premium products, pls provide a premium software update. Pfffttt...

If you think your battery life used to be so much better with gb why don't you go back to gb? No obligation to use ics. I use 4.0.4 with goku kernel and battery life is at least as good as it was under gb. 4 - 5 hours of usage, lasts a full working day.

Okay, so ive done quite lots of tricky stuff before, and guess what.. I hv found the solution for now.I hope...
1.Charge battery with phone turned on until galaxy is fully charged
2.UnplugTurn off phone and charge for one hour
3.UnplugTurn galaxy on, wait 3 minutesTurn off phone and charge for one hour
4.Reboot
And now my batt is coming back to its normal performance... I get around 11hrs 45 min on standby and at least 6hrs of moderate usage.... Thank god. Hopefully it will last..

I feel like having the same autonomy like GB since I went on 404.

lol email push 5 min, dont think you know push technology...
Anyways, those six hours is not with screen on all the time.
Doing the steps I mentioned however will force a full clean install. Then test without restoring apps battery, you will be amazed. Then install in batches or one by bone to eliminate possible culprit that impacts battery life.
Perhaps even better to go to samsung/shop where you bought and ask them to fix it If it is battery they will catch it and replace Less risk for you

Obtained this info from another thread:
about the alarm_rtc wakelock;
install terminal emulator from market and type these commands:
- su ( followed by ENTER )
- dumpsys alarm ( followed by ENTER )
it will dump some info on your screen
scroll upwards a bit and search for 'Alarm Stats'
here you can find the processes that keep your phone from deep sleep

i think it's a rom problem,i face it when i'm on that build,but now i change to gueste.. and everything works,try to change kernel.. or rom..

I also had this problem on Parandroid CM10, no sign of life from the phone at all.
However, I reflashed the rom and now it works great.

Ok rom issue then. I will reflash it with a different one and kernel. Any kernel recomendations?

Happened to me on gueste2x v3.8 last night while I was USB tethering...and I was just pushing for a record time running made it to 160 hours and had to pull battery out to get it working again. As mentioned already, it's probably something to do about background data/wifi activity.
Nevertheless, I still recommend gueste2x v3.8 :thumbup: Give it a try

I kept having this issue with stock CM & faux kernel. I resolved it finally by replacing the battery with a new one.

How to return back to ICS from JB without data loss.

I use my phone and its features mostly for my work stuff. So it is always a trouble making backups and yet lost some good piece of it. This is the reason i dont frequently change my phones rom. Yes i try them but just forba while or maybe a week or two. But then return back to the stock. I was on my stock ICS which was rooted via the exynos abuse with no cwm or any other bootloader. 2 days back i got an update of about 501 mb and it updated me to JB without formattibg my phone.
I was happy thinking that i received it very late hoping it will be fixed and tweaked from known issues. But unfortunately it isnt and full with crapoy bloatwares which i uninstalled using hiuninstall utility. The lag is gone but the huge battery drain is kind of annoying. I cant just keep my phone plugged in all the time.
I want to know a way by which i csn go back to ics without formatting my phone.

You will not be able to do that. If you managed to get it to boot with no wipes there would be so many FC's it wouldn't be usable the best you could do is maybe flash philz kernel for you ROM and try to flash a custom jb tw ROM there are some good ones and the if you still have bad battery drain use better battery and see what is using up your battery the most and also use CPU spy to see if your phone is going g in to deep sleep. Location services on tw uses a lot of battery you could try turning it off and see if that help.
