Anyone else notice that the battery bug isnt fixed in the 4.0.4 update or is it just me?

quantumrand

Did you try a factory reset/wipe before updating?

No i never did a reset, would that make a difference?

quantumrand

Whenever there's a problem after flashing an update, it's one of the first things to consider trying.

razvan06

Idk if this can help you ...but i have the latest Matrix kernel [18.5] on my 4.0.4 Pixel ROM ...GREAT batt life ! 2 days with games ,calls ,wi-fi ... and still 5% -> first 100%-0% discharge on it ,NO OC !

I notice that exchange services is using up a lot of data and battery. I had to delete my work email to stop it. Could that be the problem? It would be nice to find a fix for this.

When I first updated to 4.0.4 (from 2.3.6) my battery drained very quickly. Did a factory reset and speed and battery life are back to normal.

CocodaMonkey

I've noticed the battery is worse with 4.0.4. With 2.3.6 I could get 3 days pretty easy. With 4.0.4 I get about 2 days. So it's not horrible but it's certainly worse. Andriod system used to always be about 5-7% of my bat and now it sits at about 14% and I'm told that's normal for 4.0.4. So I'm pretty sure battery usage got a little worse with the update, nothing too major though.

bfksc

I don't know about that...I've been on v4.0.4 for several days and Android System is usually around 10-15%. Screen, Voice Calls, etc. are often higher, which indicates to me that although the "system" seems to take more battery, you have to remember that ICS handles certain processes a bit different from GB. With hardware acceleration you get more performance in the graphics/display, which means higher consumption for those related tasks, but lower overall battery consumption since the main CPU is not processing these tasks at lower levels.

Personally, I find battery life to be about the same overall. The first day or so I thought battery life was worse too, but then I realized I was playing with the phone more - a new OS means changes and learning the layout, so more "on" time. Now that I'm used to it, I find it's similar to GB. Overall, I find it's about the same on v4.0.4 compared to v2.3.6 GB. Just remember that you can't compare individual processes the same from major version changes to new versions as the demands of those processes often will change in each major version change.

And don't forget that although v4.0.x previously had battery issues, many users report that v4.0.4 has fixed those battery issues, hence the wide roll out of v4.0.4 to many users.

YMMV.

After I installed ICS I thought the battery was draining a bit too fast so I did a factory reset. It was "Google Services" that was at the top. Now it's *worse* ! I can't go 1/2 day without plugging in. Now it seems the big drain is my Wifi (my router is close to me but not in the "donut" area so no excuse). It's never been better than 2 (occasionally 3) bars. Removed the case it's in but reception is no better.

I downloaded Wifi On/Off which is supposed to turn off my Wifi overnight and whenever it can't find a signal but it doesn't help. Uninstalled. I've made sure Latitude isn't trying to locate me and drain things. GPS is off, Bluetooth is off. I even use System Panel to kill off any processes before going out. I'm not impressed!

I'm thinking of another reset (although the re-install of the programs is a pain - can't find the 'reset' on Play that used to be there on the Market). Yeah I know Titanium Backup works but it's not rooted.

First thing is get rid of System Panel. It's like a task killer and they are the worst app to install. Task killers are not needed at all as Android is very good at managing memory, and they are often the reason why users have battery issues in the first place.
You should definitely try another reset, and don't install System Panel this time.

AmazonAnnie

Yes, I've heard this plenty of times - I've installed System Panel since my first Android phone (LG Eve) and I rarely use it except to close down programs that won't shut down on their own. It doesn't really even register on the battery use and there is a nice monitoring part of the app that I use.

Yeah... I was afraid of that! I'll hold off on system panel this time around as you suggest. Good thing I have nothing planned this afternoon.

polatok

any one know how can i role back the previous default version?

bfksc

Why would you want to...from what I've read, V4.0.4 fixed the issues with previous versions of ICS and works pretty well. Earlier versions of ICS have several different issues.

Having said that, if you want to go back you'll need to unlock the bootloader, root the device, flash a custom recovery, wipe the device with the custom recovery, and then flash the older version.

PaulieC

Had the same horrible battery draining experience with my Sprint Nexus S. Received the 4.0.4 roll out from Sprint a few days ago. I noticed the Android OS was consistently at the top of the battery app. Did a little research, and found that disabling and clearing the data associated with Google+ can help. After a few hours today, the Screen has been a few percent better than the OS. What's funny is my Wife has the same phone, and hers is just fine. I think the factory reset will be in my near future.

Sorry for the noob question here, but when you do a factory reset, does it mess up your carrier settings or anything? I don't want to be stranded without the phone or something...

bfksc

Take screen shots of the settings and APN and such to be sure, but it should be fine. Screen shots are taken by pressing and holding Volume Down and Power at the same time for 3 seconds. The reset will also remove all your downloaded apps, texts, call log, etc., just like a new phone. The contents of your "sd card" like music, videos, etc. will not be deleted.

PaulieC

FIXED!!! SUCCESS!!! Android OS is back in the single digits! I did the factory reset, and cleared everything out. The Google+ helped, but now it's fixed. I am slowly putting the apps back. watching for problems.

tobyyoda

PaulieC, how many hours do you get between charges? I want to avoid the factory reset, my Android OS is down at 5% but I still only get 15hours - nothing like the 2+days others mention on 404.

kingsqueak

I definitely had this issue. Exchange Services was absolutely cooking my battery <3hrs life. Overnight charging couldn't keep up with the drain and it would be 71% charged in the morning.

I had to delete the Exchange account and force disable the Exchange Services and all was normal again.

I'm trying the full reset now to see if it will settle down again...hopefully it will as the work mail and calendar are pretty important via Exchange.

Will report back with the results.

thedynamix

Hi kingsqueak..

Any luck with the factory reset?

Unfortunately I'm suffering the same problem as you in that Exchange services is killing my battery and mobile data exponentially..

Let me know if you had any success with a reset???

I await holding my breathe lol .

Nick

kingsqueak

So a full wipe, no joy, Exchange Services still eating battery at an extreme rate.

I disabled contacts sync as I've seen mention it can be part of the issue and it seemed to help a bit, but still cooking the battery in ~5hrs.

I'll have to disable use of Exchange until they put out a fix. My phone has to last longer than this.

bfksc

This is a known issue with Exchange Services - a looping error is causing the CPU to work much harder than it should and it's draining the battery. More users reporting the issue will help to isolate the issue and allow a fix. See here:

Issue 24531 - android - ExchangeActiveSync (4.0.2-EAS-1.3) on Galaxy Nexus crushing Exch2003/IIS services and Nexus battery life - Android - An Open Handset Alliance Project - Google Project Hosting

The page for all bug issues is listed here:

Issues - android - Android - An Open Handset Alliance Project - Google Project Hosting

thedynamix

So there's no fix for this? Just the option to report the already known bug?

bfksc

Not yet...I would guess that the bug is hard to locate and fix because not a lot of users have reported exactly how it happens. It's like driving your car to the mechanic and saying, "my car's broken", and then waiting for him to fix it. It's going to take time if they don't know what's broken...

thedynamix

****ing Android is so shit. So much potential, but it's so amateur it's a joke.

Love my Nexus S in terms of hardware but Android is slow, buggy not the prettiest and now this.. Renders the phone pretty much useless!

Plus those Android Developer guys on Google Groups don't even approve my support thread so there's no one who will be addressing this.

Let me know if you have any luck won't ya!?

mjschmidt

Just got my update (Rogers) and I've noticed the hyper battery drain. I've gone from 85% to 77% in only 30mins, which is unusual. I usually start the day fully charged (about 95%) and end the day around 70%-ish.

I notice when I go into Settings > Battery, it shows "Media" at the top of the list using 33%. I have no idea what that is. There are no media apps running in the BG. Interestingly, right after the update this "Media" process was using 51%, and has been slowly going down.

I have NOT done a reset yet. That would be my last resort.

I thought the whole reason they put the update on hold was because of the battery drain issue!

Have you tried rebooting? The first time I booted up my phone after updating to 4.0.4, apps wouldn't autorotate into landscape mode. Simply rebooting fixed that.

mjschmidt

I've done a full reset of the phone. Disabled Google+ (which seems to be one of the culprits), and battery is better, but still doesn't seem as hearty as under 2.3.6.

I've seen people mention exchange, but I'm not using exchange for email. I'm using K9 for my pop email, and GMail.

blackphoenix

Well on mine the battery (android os/system) bug seems to be fixed... for the most parts. and i can easily squeeze out 24 hours+ of it before i will even consider recharging it. However at times system or OS will run amok and, will use more than 50% over a single night, with system being the culprit at around 56% battery usage, and the activity meter being one big solid bar, when it should only be some scattered bars. Issue is usually solved from a reboot. I have reset the phone a couple of times by now, but it still persists.

tobyyoda

For what it's worth, I've listed out my experience so far and the tweaks I've used below. It has really just been trial and error and picking up on what others have posted in various threads. My plan is to get some more data behind this by gradually turned things back on. Btw this is from disconnecting the AC charger through to the 4% remaining stage.

When I first went from 2.3.6 to 4.0.3 I was lucky to get 9 hours from a full charge, when I went to 4.0.4 I would get to about 11 hours. I've managed to get to 14 hours or so in the following way:-

- turning off the notifications I don't really need (I think Facebook is a primary offender here but not gathered the data yet).
- moved from push to 30min sync on hotmail
- disabling auto screen rotate
- don't use a live wallpaper
- restart my phone at the beginning of the charging cycle
- set 'Keep WiFi on during sleep' to Never
- turn off WiFi during the day when I know I'm not going to be using it.

My general usage profile is as follows:-
- Charge using ACfrom 11pm to 7am
- from 7:30am to around 6:30pm I'm on 3G with mediocre reception
- from 6:30pm onwards back onto WiFi
- use Good for Enterprise for my business email and that seems to behave well
- make around 10-15 calls each day

turned Facebook notifications back on and, perhaps not suprisingly, Fb took up a much larger chunk of battery usage. It's basically trimmed an hour off my battery time today.

Today I had a very similar usage profile (except made only a handful of calls) but I switched on Auto-rotate. Not made that much difference but won't quite get to 14 hours.

I guess to draw the line under this discussion I found that during a recent trip to Australia my battery life jumped to 24+hours. The only thing I changed was the SIM and hence 3G network. Back to China now and I'm back to eeking out 14 hours or so.

bfksc

I noticed in an earlier post of yours that the cell signal strength is "mediocre". I've seen the same thing with battery life, if the signal is weak, then my battery drops rather quickly. I guess the phone struggles with weak signals and tries too hard to maintain a connection to the network, which is sucking the battery dry.

I now have Jelly Bean v4.1.1 installed but I haven't had a chance to check signal strength and battery drain yet. I'll report later once I get a chance to be in a weak area.

gandhimaster

I have the same apps (in terms of google's and streaming ones like google music/spotify/beyondpod installed on both my Nexus and Nexus7. The "Media" app in battery usage is 50%+ on the Nexus and only 2% on the Nexus7. Has anybody else experienced this? Battery life on my phone has dropped through the floor since jelly bean.

this is ridiculous, I had a nexus S for a year happy till the frigging update, did a factory reset with all the pain that comes with it, android system at 70% huge battery drain, disabled everyhting might as well get my motorola startac phone out of the garage...

thanks for all suggestions but Google should try to fix this issue in the next release

bfksc

It seems after the update or a factory reset, that Media can be high on battery use for a while, especially if you use Google's backup services. This service is restoring all your old settings, apps, media, etc. so it's busy for a while getting your phone set back up the way it was. After a day or so, Media should slowly drop way down the list, or even fall off the list completely (I haven't seen Media on my list since the first week I installed JB).

Another battery issue still being reported is Exchange - the bug where it eats battery life may be fixed but another issue persists when updating where the account is constantly trying refresh. A factory reset seems to help or deleting the Exchange account and setting it up again in Jelly Bean seems to work too. I don't use Exchange so I can't confirm this.

gandhimaster

so, theory should be for me to stop resetting the phone etc and give it a week or so? I'll give that a whirl! Thank you.

bfksc

Yup...you should see Media dropping after the first 12 hours or so, depending how much you have stored with backup. If you have a large amount of stuff to restore, then it may take a day or two to settle down. And you should also let it use WiFi as it will eat into your data allotment for the month (unless you have unlimited).

gandhimaster

update... i ended up doing one final restore. This time from the recovery menu rather than settings. So far, mediaserver has behaved normally. I'd left it on charge and it was still running 12 hours later!

Anyhow, the only app ive done differently so far is esfile exlorer. I normally add google drive/dropbox etc to its net folder. Maybe that was it? Altho its instlled that way on my nexus7 without causing mediaserver to go mental. Ive removed that app now anyway to be sure. /thanks for your help!

gandhimaster

Actually, scrap that. After latest reboot (no reason just turned phone off) media scanner has returned! Seems to have stopped at 15mb as usual but still running. Sad face.

gandhimaster

update - been testing various things, and the latest thing that i found was by deleting the data/uninstalling "Pocket" app and rebooting the media service only ran for a minute and then stopped. Pocket's data was 700mb+ and the last time i was deleting data etc i had cleared that too.

I didnt link this app to the behaviour but it does make sense considering Pocket contains music and video etc ive saved for offline reading later. At one point, i'd had the app setup so that it would not automatically download content, and during that time the mediascanner behaved normally. I'm guessing this means that once all that data had been scanned, it would work ok but it had ran for 12+ hours when Pocket had 700mb+.

Sorry for the rant, i hope this helps some people. Assuming it is what i think it is!
