EDIT

I was able to solve my battery issue by

formatting my SD card

. Something on there was causing the battery to drain 2-3 times more quickly than normal. After formatting, I went from 6-8 hour battery life to around 20 hours with significant usage (Google, Exchange, IMAP, Facebook all on push, 3G+Bluetooth+GPS on, 4G and wifi as needed for extra speed).

Important to note, I am not entirely convinced that the Android OS and battery drain are related since

I still have Android OS near if not at the top of my battery consumption screen

, but the improved actual longevity is very significant. I recommend anyone having their battery run out format their SD card (and possibly USB storage) and see if that helps (obviously back up any important data first!). Good luck! :)

ORIGINAL POST

I'm getting pretty bad battery life, and it looks like "Android OS" is consuming most of it. I've rebooted (as suggested in other threads), checked OS Monitor for high-CPU usage processes, but nothing stands out. This is un-rooted, stock OS with no third party launchers installed.

I have a feeling if this issue was fixed, I'd be getting great battery life. This happening to anyone else? :confused:

Screenshots show the device at 38% after 6.5 hours off the charger.
[Samsung Epic 4G Touch] Dfolt:
if u using a 2.3.3 based rom is normal, that bug is fixed at 2.3.4 and 2.3.5
[Samsung Epic 4G Touch] xak944:
My device is running 2.3.4.
[Samsung Epic 4G Touch] MoMatt:
That's an awful lot of awake time with no screen on time. Do you have things updating in the background frequently? I.e. social hub, Facebook, news widgets?

And not to be too obvious, but is your 4g antenna turned on?
[Samsung Epic 4G Touch] xak944:
No, I don't. I have fewer widgets and fewer accounts (haven't set up my work Exchange yet) than I previously had on my EVO, which got great battery life.

I've been on Android over a year and am quite familiar with how it works... I'm just unfamiliar with Samsung specifically and unrooted devices ;) and was hoping someone might have a similar experience.
[Samsung Epic 4G Touch] Zurginator:
I have the same thing. Significantly more awake time then screen on time, and Android OS eating the battery. Also stock.
[Samsung Epic 4G Touch] mkhanson:
Same here too
[Samsung Epic 4G Touch] mjdoran:
I had this exact issue and no longer do. Here is what I did and posted in another thread:

OK I hope someone finds this useful and/or can verify. I was one of those people getting awful battery life, meaning lucky to last 8 hours from 100% to 0%. The "Android OS" process would take hours of CPU time. Now it will take up maybe 30 min over the course of the day. Here is the only thing I did between the time it went from bad to good. I changed the wifi sleep policy. It is by default (for me at least) set to never. I changed it to "when the screen turns off" and left it there for about an hour. Then went in and changed it back to never. From the point of doing this my battery life has been great.

I know it sounds strange but it seems to have worked for me so I thought I would share.
[Samsung Epic 4G Touch] xak944:
Thanks for the suggestion!

I made the change, hopefully it will help, although I'm reluctant since I haven't had wifi on all day and my battery has been dropping like a rock. Here's hoping... will report back if it helps. :)
[Samsung Epic 4G Touch] mjdoran:
I rarely use wifi as well but this setting seemed to affect the phone in general, if your using wifi or not. I might just be crazy though. Either way I no longer have the issue so :P
[Samsung Epic 4G Touch] JoeBruin32:
does the google voice widget pull data in the background or is it a push thing?
[Samsung Epic 4G Touch] Kn0wBuddy:
I'm seeing high usage (60+%) by AndroidOS also (stock, unrooted, not using WiFi, not using 4G), although battery life has not been bad that I have noticed.

Watchdog Lite indicates that this is primarily due to two processes:

events/0

suspend
[Samsung Epic 4G Touch] limeaid:
I'm having the exact same issue. Stupid question here (I've already tried to find it and googled it too, but no success.

Where do you change the wifi policy? I don't see it under wifi settings
[Samsung Epic 4G Touch] xak944:
Wifi Settings > Menu > Advanced ;)
[Samsung Epic 4G Touch] mjdoran:
Settings >> Wireless and Networks >> Wi-Fi settings

Then press the menu button and then advanced.

Should then be the first option "Wi-Fi sleep policy".
[Samsung Epic 4G Touch] limeaid:
Thanks. Like everyone else, I'm going to try this out and report back after a day or so
[Samsung Epic 4G Touch] xak944:
I'm trying to get into the 'INFO' section to view wake locks for battery usage clues. I've tried *#INFO*1111# (as mentioned here) and the old *#*#INFO*#*# to no avail. Anyone been able to get to the diagnostic screen from the dialer?
[Samsung Epic 4G Touch] JoeBruin32:
Are people with battery problems using widgetlocker?
[Samsung Epic 4G Touch] xak944:
Interesting. I installed it yesterday. Will try removing it if the wifi setting doesn't work...

Is anyone with the "Android OS" battery drain not using widgetlocker?
[Samsung Epic 4G Touch] mjdoran:
I am not and was not using it.

In Brazil we have a public petition asking to LG agility on this. Ice Cream Sandwich will be released next month and we can't get gingerbread yet:

The original link (in portuguese/br) is:

http://www.peticaopublica.com.br/PeticaoVer.aspx?pi=LGO2X

Citizens undersigned, here by request comes, a position on the software update from mobile phone model LG P990 OPTIMUS 2X, since the LG device sells in Brazil as the "largest processing power in the world", and in fact, it's extremely outdated, does not match the expectations of buyers.

Around the world LG is delaying all the deadlines for update our phones, disregarding the consumers.

It's unacceptable that our smartphones dont run the system 2.3, since this same hardware is already running newer S.O on T-Mobile U.S. version - LG G2X since july/2011.

We would, at least have a real date, since we are customers of the brand, and we was buying the phone, the update was a decisive factor. We trust on the responsibility of the LGE in Brazil, to provide some kind of information to its Brazilian customers.
​

If you want to help too, sign the petition and join us (translated to english):

[LG Optimus 2x] stylez:
Can totally agree about how the LG O2x has hardware that deserves the latest build but do think we expect too much from LG since carrier related too.. many years ago there would be hardly any updates on WM yet the community pushed with leaked builds and the users got to get fresh builds with most bugs solved by chefs etc... my point being take a look @ class action taken over the 3D drivers issues with Kaiser it really gets no where I'm sure LG will come up with the goods its just a waiting game in the meantime flash user created builds and set your phone up too rock!
[LG Optimus 2x] ilmancr:
i hope its work bro...
[LG Optimus 2x] lucfig:
I dont really care. We have topogigi 1.7, GR3 and CM7. Surely these are better than what LG will bring to us.

I don´t want any official gingerbread anymore. Now I want ICS!

If LG is going to update to ICS I dont know, but I will jump to CM8, even without a2dp and fm radio.
[LG Optimus 2x] tpowell.ca:
hope so too.
[LG Optimus 2x] blakki73:
Signed all :-) The problem is that i want FM radio, A2DP, HDMI, and i also want USB host, because tegra 2 supports it. Only LG can give us theese features fully working.

P.s. Sorry for my very bad English.

[Droid Incredible Q&A, Help & Troubleshooting] Sgt_Bilbo:
One of the partners here at my place of employment found an Incredible and thought it might still be alive, but the screen was toast. SO...he ordered a new screen and got it installed. The screen won't turn on (did verify that the old was AMOLED and not SLCD), but the phone is acting like its still alive. I was able to boot it into HBOOT (?) holding the Vol-Down button and turning the phone on. ADB sees the phone as attached, but "offline".

Is it possible the screen was bad and the phone's still viable, or is this phone a hopeless cause? Are there any diagnostics I can run via ADB or some other program? (please forgive the newb-ness of the question...I'm familiar with ROM flashing, but not much beyond that).

Thanks for any assistance/guidance/condolences you can provide.
[Droid Incredible Q&A, Help & Troubleshooting] POQbum:
Okay so..

1) You checked to make sure you ordered the correct screen

2) The new screen did not work, same as the old screen that was on there before

Sounds like someone dropped it in water and messed up the internal board. Doesn't sound like a screen problem if you have a completely new screen and even that didn't work (assuming you connected it correctly and that the connectors are in-tact and working)

Beyond my knowledge too, hopefully someone smart will chime in :rolleyes:

Hi, I finally entered the world of partitioning my sd card after the davlik cache prevented me from installing any more apps (even though my internal storage showed 120mb free).

I got link2sd working and all is good, but I am wondering if I need to take any additional steps when upgrading or flashing new ROM's. I'm on Jerry's 9/19 build and only plan on updating if there are any major enhancements.

Thanks for your help. I'm just not sure if there's anything additional steps due to having a partition.

Have the Yahoo email app. Works great. I use the stock email client for my work exchange account and the Yahoo app for my sbcglobal accounts. The Yahoo app makes a standard sound but I would like to assign a custom notification sound. Want to use the old AOL You Got Mail sound. I have custom sounds for Handcent and I can add a custom sound to the stock email client but would like to add one to the Yahoo client. Anyone know how to do this? I tried to add it as system default but all it did was assign it to the stock messaging widget.
[Xoom Q&A, Help & Troubleshooting] thebrenda:
What software can be used to do a full image backup? And would you be able to run the backup if the device does not boot? Can you write to the internal storage from antoher connected device?
[Xoom Q&A, Help & Troubleshooting] okantomi:
If you unlock and root your Xoom you will install a custom ClockworkMod recovery (two custom versions available for the Xoom made by developers here in the xda Xoom forum) and with that you will be able to make a nandroid backup of your system image, to either the external micro sdcard (solarnz v3.2.0.0 R4c Recovery) or to a choice of media, I think (Rogue Recovery using v4.).

You would be able to restore from your saved nandroid by booting into the recovery menu (volume up + power to get to the red dual core logo, wait 3 seconds, then volume down, and then volume up and into your recovery menu).

The PC sees the Xoom as an MTP device. It doesn't act as a mass storage device (at this time) so while there are ways get info into it, it's not the same as actually writing to the internal storage.
[Xoom Q&A, Help & Troubleshooting] thebrenda:
is there any commercially available backup software?

No only the free recoveries. You can also just download the images from my sticky, its stock images from Motorola.

[Xoom Q&A, Help & Troubleshooting] okantomi:
To back up apps and data, whatever you choose you can use Titanium Backup on the schedule of your choice. For backing up system image its a nandroid tthru CWM. As a programmer you might figure out a way to schedule auto backups...
[Xoom Q&A, Help & Troubleshooting] stlsaint:
Using the method mentioned above I use the rogue recovery to make the nandroid back up and if you have a microsd you can tell the recovery to save the backup to the sdcard for external backups.
[Xoom Q&A, Help & Troubleshooting] bwcorvus:
This is what recovery backups are. You setup, run a nand backup. When something goes wrong, boot into recovery, restore, watch TV, reboot.

[Samsung Epic 4G Touch] r3a1ist:
On the phone with wirefly.com. Seems as though they've swapped shipping labels and sent me a two Nexus S's rather than my single ET4G. LoL, the saga continues. On the phone with them. Trying to figure out how I stick this to them. Hey Brian, how's my Galaxy S II? Kinda wishing you hadn't gone for the free Nexus S's for free with a 2 year agreement huh? What are these people thinking?

---------- Post added at 03:36 PM ---------- Previous post was at 03:30 PM ----------

You gotta live under a rock to be on a hundred and thirty dollar a month family plan, sign up for 2 years and get not 1 but 2 free Nexus S's. If he is the one that ended up with my GSII hopefully that's his wake up call. I'm about to call him and tell him to tell wirefly to keep the nexus and send him GSII's lol. I got his number. I feel sorry for him.
[Samsung Epic 4G Touch] Silent25r:
I would hit them hard on shipping and on % taking off the price of my device. I would let them know how desperate I was for this phone and how upset the contents of this package made me. We'd be on the phone for about a hour talking that one out because now I have to wait for the device to be shipped again?

I would even slide in a BB complaint if they didn't feel like coming to an agreement with me. This is a pretty large mistake. One a company shouldn't make with a high end device during it's first week of demand.

Edit: I misunderstood. So they are having you take care of the problem? Is it local? And yea, I would try to have wirefly send them 2 GSII's. That would be one very confused family to find one phone in their box.
[Samsung Epic 4G Touch] r3a1ist:
They're sending out my gsII expedited with a free bluetooth headset

---------- Post added at 04:58 PM ---------- Previous post was at 04:52 PM ----------

The other family ordered two Nexus S's not GSII's, I have them. About to ship them back to wirefly. Instead of receiving two Nexus S's they received a single ET4G. I hope they open it up and fall in love with it and cancel their order and order two ET4G's instead. It's a shame their signing 2 year agreements with the previous model.
[G2 and Desire Z Android Development] L-ViZ:
great :) have been waiting for this release :)
[G2 and Desire Z Android Development] madmaxx82:
Hehe thanks.

BTW: version 2.1.6 RC2 should be rock solid, just like a "final".

Except *maybe* for the optional tar backups feature (which can be switched on optionally).

It was tested very much, but as it is so new, noone knows if there are any "hidden" bugs with it that could possibly appear in the future ;)
[G2 and Desire Z Android Development] tsubus:
awesome, will give it a whirl!
[G2 and Desire Z Android Development] xT4Z1N4TRx:
So is this better than CWM 5?

Sent from my Desire Z running @ 2GHZ
[G2 and Desire Z Android Development] tsubus:
being that cwm5 randomly freezes your phone, i don't see how it could be any worse. so far seems to have more features than 3.0.2.4 and i like the tar backup option, much quicker.
[G2 and Desire Z Android Development] madmaxx82:
I wouldn't say better, it's different.

It has a lot more features and really detects your file systems correctly and preserves them on backup/restore.

CWMR5 is the first version that does that too, but at least in my case it failed.. when I restore a backup with it, all my partitions are formatted ext3 again (when they were ext4 as I created the backup)

But hey, I'm biased :D

Try it yourself and see what you like better :)

If you want, take a look what ppl say in the other 4ext threads:

well im sold, i defenetly have to this recovery, it has the feature iv been wating for, to disable md5 checksum

edit: dude i can i just say thank you, omfg this recovery is to much, battery info, parttion size info and rom name all in recovery? this is just amazing. i literately have no words man
[G2 and Desire Z Android Development] madmaxx82:
Hi :) thanks

But it doesn't have that feature to disable md5checksums.

However you can use Recovery Control to verify any of your backups for correct md5sums. If they don't match, you can als use it to "correct" them.

This is not recommended of course, since it indicates that there's a problem with that backup's data integrity. However sometimes ppl need exactly that backup badly.. so they can *try* to restore it anyway.

Disabling md5sum checks completely is a really bad idea.

I got one request about that from a guy with a phone that had a defect in handling sdcard memory. He tried numerous sdcards but still had that problem for a month.. any md5sumchecks fail for him.

He asked me to include a switch to disable them for him.

In the meanwhile he has sent his phone in for repair.

I might do that and add that switch, but it's not a very high priority since there is really much todo.

[G2 and Desire Z Android Development] madmaxx82:
Sorry to ask so many questions.. I first thought you used toggle usb storage a few times and then went into mount and storage and manually unmounted /sdcard there.

So after a few times toggle/untoggle it says it cannot unmount /sdcard?

Maybe it's already unmounted.

When this happens please check if it's mounted.

If there's really a bug, send me a bugreport including the recovery.log via the app.

I enable usb storage (just once), i copy the files from/to my pc, then i disable usb storage and i go in the mount section. the sdcard looks mounted (it gives me the option "unmount /sdcard", but i cannot unmount it, i get an error (this does not happen every time, but it has happened a few times already).
[G2 and Desire Z Android Development] madmaxx82:
Do you safely remove the sdcard from your OS before leaving the toggle usb storage menu?
