Yes my Prime went from 40% battery life to totally dead when I woke up this morning....... I knew when they finally found a fix for the lockup issue they would screw everyone else over somehow this is last straw I am returning this once and for all.
EDIT: This appears to have been a one time thing I have tested the battery with sleep since this happened this morning and everything appears to be just fine..... also my antutu benchmark scores even went up a little
EDIT: Well nevermind my battery life sucks drains 40% in 2 hours at 25% brightness just browsing the web my Wi-Fi also randomly now disconnects and I have to click in to network settings and all of a sudden it will reconnect. I want 1.11 back or my money back for the Prime.

Yes it was read Garys notes in official thread for his 2/8 update.....
Same experience for me. The latest update has killed my once great battery life. I'm kind of pissed, considering I never suffered from the reboot/freezing issues that the update was made to address.

o which source are you referring to. A thread here on the forum?
um you shouldn't b jumping to conclusions, in my experience it is not unusual to have crap battery life after a firmware upgrade, aspecially if you have a lot of apps, it has to rebuild caches and all that, so usualy sorts it self out after a couple of days.
The other thing is we can't see what apps could be causing battery drain as Asus hasn't enabled it yet.

Jumping to conclusions? I have never woke up in the morning to turn my Prime on and find it was turned off because the battery had died I think that's as conclusive as can be.

That's not necessarily true, sometimes a broken app, incompatible app, or apps that crashed can keep the processor running. When I first got my galaxy sII the battery drains like crazy. But after a factory reset it was 100 times better. I wouldn't jump straight to conclusion with a one time thing. After all, pics, quad core are still new.

BUT if only 1 thing changed, the OTA update, you can rule that logic out. If he got the OTA update AND changed a bunch of stuff that is possible. As I read it, only change is OTA update and thus, you can start to narrow down the cause.

The system update is not draining the battery life at all, if anything the way the system ha been adjusted to utilize the cores, it should save some battery life. battery drain is caused by an app running in the background, tat is probably not closing properly. Check to see if anything is running in the background, or maybe an app that you recently installed is not working properly. My battery can go a day without needed to be recharged, and this is with heavy gaming/app usage, as well as other prime owners whom have updated. Please try to root out another cause of the problem before just assuming its due to the update.

Yes it did, and mine and hundreds of other owners have not had any battery issue, so I don't see it causing battery issues for some and not others. Have you recently installed any new apps/games? Did you try a fresh reboot? I'm not calling you a liar, I'm just saying check for other possible causes. The speed of the cores have been adjusted somewhat with the new update to help save battery life. Use the link provided a few posts above to see whats running and using the most battery on your device..I bet that's what is killing yuor battery
Well if this is true mine should be off when I get home since i haven't used it since last night. We'll see.
Oddly enough, I had a battery issue yesterday as well - but I have not received OTA .13, my Prime is on 11.1
I left my tablet in my work bag most of the day, in sleep mode. Around 4 PM I go to use it, and it is AMAZINGLY warm/hot, and the battery is dead. I cannot remember what I was using the night before, but something made the processor churn all day, and eventually kill the battery.
I think I did leave it on Performance mode - but can't for the life of me think what could have caused this to happen.
I know - not very helpful as I am not on .13 - but just pointing out yours could have been a fluke.
Charged when I got home last night - and all seems fine today.......

Exactly, this just means that your Prime was *working* constantly, which means that there was an app/game that was running constantly without your knowledge. try a fresh reboot and see if that helps, also, try to find the culprit which is causing your prime to stay active.

You wouldn't be the first one to complain about the sleep mode battery drain on 11.1. I am also quite sure that the .13 version is heavily based on that 11.1 beta.
After upgrading to ICS (via kies) the battery really sucks. Last for a whole day if im lucky. Is this normal??

From what I've heard, it's usually improved - BUT some power management bugs that affected stock Gingerbread kernels but were fixed in all custom kernels are still present in ICS, such as the good old fuel_alerted wakelock - so while it's better when working well, it's more prone to breaking.
I'm happy if my battery lasts for a day as i'm always messing with it(one of these days I might use it to make a phone call)! Have you tried putting it on charge at bedtime? I find that helps a lot.

I would try to avoid over-charging it, it's not good for any battery. Once it hits 100% (so long as it's correctly calibrated) unplug and use as normal.

same here i upgraded to ICS xxlpq and have been using it for 3 days, im struggling to get a day out of it ... its exactly the same setup as when i ran XEU (KI4) 2.3.4 unbranded UK. I noticed ram usage has increased as well as the amount of system processes. both times I rooted and removed bloatware. when my contract runs out in 6 months I will be looking at either a pure asop phone or an iphone 5, The galaxy s2 has a great screen but the batterylife if weak no matter what custom rom and custom kernal is running. Also I can get a wifi signal in my bedroom with my laptop and my old iphone 3gs but nothing with the s2.
Also please can anyone advise what the best pure and minimilistic asop rom will be for the galaxy s2 ive read cm9 mite be soon but is there anything thats great for battery life ? ...... thanks for you time in advance :=)

Upgrading to custom ICS roms is usually a great way to enhance your battery life, because they're always containing tweaks and optimizations!
This worked for me
Device: GT-I9100 (Samsung Galaxy S2 international)
Carrier: Smartone
Country / Language: Hong Kong
OS / Browser / build number (if applicable): ICS 4.0.3/IML74K.ZSLPE
I can confirm that I have resolved the battery drain issue after upgrading to ICS on my device. The problem was partial wake locks caused by the exchange service.
One of these measures fixed the problem for me (it might have been any of these, although I have a strong suspicion that the factory reset is the only relevant one):
- factory reset of phone; didn't restore the settings and accounts, but set them up manually
- wiped cache
- did not reinstall ADW launcher
Hope that helps.
The good news is that now the battery life is definitely better than it was on Gingerbread.

This isn't really true. Once it hits 100% it pretty much runs off the charger.
By depleting it all the time you are ruining the battery that way

Leaving your phone on charge longer than is absolutely necessary ie taking it off charge as soon as it gets to 100% will not affect your battery life and there is also no need to manually calibrate the battery. I installed DXLP7 and was getting poor battery life due to a wakelock, I found and dealt with the cause and immediately battery life improved. In my experience battery life on ICS is as good as it was in gingerbread. Better battery stats is your friend.

I had upgraded my sgs2 to ics yesterday. The new version is draining the battery very seriously. In the previous version, my sgs2 could last for about 12 hours from a fully charged state. But now the version can only last for 6 hours, which is really unacceptable.
Is deep sleep? You can check with CPU-Spy. If not, remove the battery a few minutes and then returned.

I had huge battery drain issues from exchange and email waking the device and constantly doing something. Removed the accounts and then set them up again. Like night and day now, better than gb. On LP7 and never wiped.
Cheers

Keep a look with BetterBatteryStats, and see if there are any apps messing up.
I have better batterylife with ICS by a margin.
And about leaving the charger on during night, these are kind of myths really, you can keep it on without any worries, and also charge it without being totally drained.
Most of these thoughts come from the old Ni-Cd times with memory effect.
I had removed the Exchange Account yesterday and the battery drain problem disappeared. The account was added back after about 10 hours. The battery usage is now back to normal (a little bit better than the situation before the ics upgarde). Thanks for your hint.
Cheers.
SG S2 ICS Battery drain issue
Had upgraded to ICS when it launched in India and literally went berserk due to the battery drain issue. Googled and googled, found a lot of things, tried most of them (except for changing ROMs).
Then, Voila, last 4 days - a complete twist to my sorry tale. I first disabled the phone backup option (to Google), did a factory reset, said No to most of the options that are asked on restart, and didnt install the earlier applications from the Play store en masse (earlier, had a number of games and other 'what I thought was useful' apps). Now, only have the basic apps plus Poweramp, Shazam and NQ Mobile added. And the result - the battery is back to normal. Phew....big relief as I use the phone pretty much for mails, music, phone.
I want yo add some thing very annoying, I discovered today after upgrading to Resurrection ROM.
In fact, even with the device connected to my car power supply and using Copilot for about 1 hour, the battery continued it's discharge instead of charging.
So what to say and what to do?
Cheers
Hello, I have installed BetterBatteryStats and CPU SPY, because I noticed that I had a faster than normal battery consumption when the tab was left alone.
I made a 30 mins test Wifi OFF, Flight Mode On, where the 29 mins of them showed me l2_hsic under Kernel Wakelock -> Since Unplugged.
Does anyone know what causes this and how to prevent it ?
Thank you.
( I am running Stock ICS 4.0.4 rooted)
Same problem here.
I am also having this issue as well using stock ics.
Hopefully someone might have an idea on solving this issue.
seems its a bug in 4.03 or 4.04 Roms , I searched internet and could not find any solution , The idea is this kernel wakelock is caused by some settings related issues like gps or wife or... , now I'm doing some investigation and try to find the root cause, however I wish an expert could bring some solution here
As I promised to report here is what I experienced:
My Tablet is P7500 and I did wipe , remove many applications , put in flight mode , disable this and that ,..... none of them where effective
and finally:
2 weeks ago I removed my simcard from tablet , Just to try to solve the issue I reinsert the sim and as you can see in attachment after around 45 minutes no l2_hsic wakelock .
what I mentioned above doesnt mean everybody have the same issue but I think its related to the sim and network discovery because during last 2 weeks I received notification in my status bar that says can not find network although it was on flight mode

Hi,
I have the exact same problem.
Tried all possible solutions with no result.
The only way is to let the Flight mode OFF, at least in my case, with stock rom TPH, WLP5.
I'm going nuts with this problem.
Yesterday I thought I had found the problem. DId several tests of getting in and out of the Flight Mode and everything was looking perfect, 5 & 6 hours of deep sleep. Then i connected a usb flash drive, that apparently also causes a kernel problem (see other posts about usb unmount). Rebooted the Tablet to solve the problem and here i go again with the l2_hsic preventing the device to deep sleep....:crying:
Hello,
I have the exact same problem and it's driving me crazy. Was anyone able to find out something new?
Thanks,
hugo.
A Custom ROM is the Solution
Hey guys, I am also a proud owner of the Galaxy Tab 10.1 GT-P7500 but unfortunately, Samsung forgot about their flagship tablet and screwed up the kernel in an otherwise utterly awesome ICS Update. The only method to solve this problem is flashing another ROM no other go. This fixed the Deep Sleep issue for me, 12 and a half hours and I'm only down to 96%. So I suggest you Root your tab ( Instructions in this link:http://www.youtube.com/watch?v=kBd9gMFCCrA ) and flash Toldo's JellyBeanRom ICS v6 ( This link:http://forum.xda-developers.com/showthread.php?t=1813651 ) and then enjoy the great Honeycomb battery standby on ICS (If you can't understand how to flash the ROM PM me :good
Happy Flashing Guys
i have toldo jellybeanrom v6 already flashed few weeks ago.. nothings changed, battery drain still remaining.
The problem is still there. AOKP 4.1.1 JellyBean, P7500 with sim card in. Same on CM10.
BTW. This is not a system issue (ICS or JellyBean). Rather something wrong in the kernels that come from Samsung. On my HTC One X (ICS) there is no such issue. Maybe some skilled developer could look at the difference in the source of this module between HOX and P7500?
Originally Posted by funky81

Code:
./drivers/misc/modem_if/modem_link_device_hsic.c:wake_lock_init(&pm_data->l2_wake, WAKE_LOCK_SUSPEND, "l2_hsic");
I will try to update the code w/ Samsung Galaxy S3 source code in my kernel...
I will inform you if there's any progress with this

Hi,
I have recently (half a week ago) updated my SII to Jelly Bean from ICS. It's fully stock without root. However, I noticed right away that the battery started draining very quickly and the phone sometimes gets hot. Did a factory reset. Factory reset the phone and format the internal SD and remove the external SD. Didn't help in the slightest. Phone starts draining after resetting. I have tried to flash another stock JB ROM (XEU) and afterwards factory reset the phone again. No dice. I installed CPU Spy to see CPU consumption and it says the phone didn't go into deep sleep at all and 95% of the time it was at 200 Mhz over an 8 hour period or so. So there's a wakelock that's keeping the phone continuously on.
At first, "Media" in battery settings in Settings was the culprit, it drained about 50% of the battery. I have searched the web and it's a pretty common battery drain on JB. I did try to disable the service and its battery consumption went down dramatically. But for some reason it turned on again. But right now Android OS and Android System are both draining most of the battery. I have also installed BetterBatteryStats and according to that app there is a partial wakelock called "NlpWakeLock" by Google Services that's draining most of the battery. Last night, around 60% of the battery got drained overnight (80% > 23% to be precise). Which, clearly, is unacceptable.
I'm at my wits end. I have no idea how to solve this and because I really like the new JB features I don't want to go back to ICS (I did a fresh ICS install and the battery drained 2% overnight which is how it's supposed to be).
If there's any information you need to know let me know. Any help is appreciated!
Go back to GB with speedmod kernel is an option.

Do you mean going back to Gingerbread? I haven't figured out what the speedmod kernel is yet but if I were to switch back I would rather switch back to ICS. But preferably I'd stick to JB since I do love all the new features and options. I'm willing to flash another JB ROM without the battery drain issue. However, all stock ROMs that I have tried had the issue.
Do you know of any good JB ROM? I prefer to keep it as stock as possible. I did root when I had ICS installed though.
Battery Drainage is very common in JB Stock

Hey Kaigo ,

Well I had found a solution to this problem You can try installing the JB France update (XEF) & the UAE update (XSG)
It worked pretty well for me Try it and let me know if it worked for you

Wow, nice. Exactly what I'm looking for! I'm downloading the XEF update as I'm typing this. I'm going to try that and I will let you know the result.

Do you bother reading the posts or just have a compulsion to post any old crap.
I see your advising people how to root,then you open up a new thread asking for help about rooting your phone.
And you are continuing to spam threads posting what other people have said already.

Well repeating other peoples posts isnt helping anybody.
An update. I've installed the XEF update initially it had the same draining issue. However, I've also cleared cache and data in recovery mode and it seems to have solved most of the issue. I've got pretty good battery life now (about 1%/h idle).
But I did find another culprit draining the battery which is Dropbox. According to BBS the processes "wlan_rx_wake" and "h2_hsic" were draining the battery but I've uninstalled Dropbox now and it seems to have solved the issue. I really use Dropbox regularly though. Anyone got any idea what could be causing that?
Thanks for the help so far everyone! :laugh:

I have always had that feature disabled since I don't want to use it anyway. I have no clue what could be causing it. I want to use a packet sniffer to see what is sending and receiving data but the phone isn't rooted so I can't really do that unfortunately.
Hold on, I'ma freeze it with TiBu.
Test time.
PS: You really need to root that phone.

I just greenify Dropbox (actually, all apps which rely on an internet connection). Unfortunately for you, it requires root. IMHO, almost worth rooting for, although there's many better reasons than that.
Greenify is almost like a temporary freezing of the app, by stopping all background processes for the app. They automatically restart when you launch the app, and automatically turn off when the phone goes to deep sleep.

Wow
Im glad the XEF update helped
Well Dropbox always keeps on syncing stuff from the cloud and that might the real cause You should disable all the automatic syncing and keep it to manual sync as it syncs only on your commands and saves your battery!!

Check how much data is being downloaded. If a lot is being downloaded off WiFi, switch it off and see if that stops your drain. Then switch off Data on your cellular. Just to check which one's causing the drain. Believe it or not, I just rebooted my home wifi router and battery drain issue was over on my Galaxy S2.

I had previously rooted my phone when I was on ICS. I never used it too often though. I wanted to use Nandroid. I have no clue how to root JB though, without flashing a modded kernel (which I did with ICS).

That's very interesting. This might just be a good reason to root the phone. So I can use network log or shark to see which apps are sending and/or receiving data. I have this feeling Dropbox is going to be one of them..

Hmm, but I guess that you can't really freeze apps like Whatsapp, since you wouldn't be able to receive any messages then until you turn on your phone. But I'm getting convinced to root the phone again so I'm definitely going to give it a try.
I installed [JB 4.3.1] CM10.2/SGT7 for a week now, I didn't changed anything yet and everything is stock as it is when it was installed. But from day 1 I installed this rom there seems to be a battery leak or something like that, because when I put it away to go for a sleep I wake up the next morning with a empty battery. Is this a bug or do I need to change a setting?

This way you can check if the tab is actually going to the deepsleep state. If it doesn't, take a look at the wakelocks.
