Ok, so I´d like to post this directly to the development forum but I´m not allowed to due to my post count.
Anyway, reading through the related threads, I know I´m not the only one with the following issue.
I used the EOS 1.0 stable on my MZ601 (European/German) since it came out and it was pretty awesome. Battery life was good, and after I wiped cache and dalvik cache once, deep sleep worked like a charme.
Uptime with light usage was between 4 and 5 days
About 3 weeks ago, I upgraded to EOS 2.0 stable and my battery life is a nightmare.
Xoom eats away a full charge in about 1.5 days of just laying around.
I did not use it on purpose to check how long it will take.
Sure I wiped cache and dalvik like before, but nothing helps.
CPU Spy tells me this...
the Tab is not brought back from deep sleep by some app or system call.
The Xoom doesn´t even goes into deep sleep, not at all.
It runs on 266mHz all the time, and AndroidOS consumes allmost 90% of the battery.
Any advice about what to do next?
Even given the fact that 2.0 is a fantastic release and I don´t want to, I consider going back to 1.0 at the moment.
On mine it seems to relate to specific apps. If I reboot, and run nothing, then it does go to deep sleep. If I use a few apps, then it does deep sleep some, but not as it used to.
I have not figured out which apps, or why the change with the upgrade. But one of the apps that seems to greatly reduce deep sleep is email (with exchange). Even though I have it set to never check my mail(except manually) it seems to have wake up alarms that reduce deep sleep and battery like a bunch. If I run mail after a reboot.
Sent from my Xoom using XDA
Use EOS latest nightly (build74).
In older builds (before 74) I also had this issue.
Now all is fine.

I've been having general horrible battery problems with my Sensation on stock Sense and Miui.us. I just installed HyperSensation and Faux 0.2.3 kernel with a full wipe and reset the battery calibration thinger.
First 2 charge/drain cycles were yesterday (got around 5.5 hours as has been normal for the last 2 weeks) and after the second drain to 1% I plugged in AC and went to bed. This morning I checked Battery Monitor (not the Beta or paid, so I'm aware the mA reading may be incorrect/offset on Sensation).
The graph overnight shows some odd spikes every 50 minutes draining the battery. This is the first night I've been looking at my graphs so I'm not sure if this is regular or a separate issue from my normal battery hell.
I've included a screenshot of everything I could think of including Battery Monitor and SetCPU profiles. Re running apps, some I've never run before, the only other one on the 2nd page was Thumb Keyboard.
I would really appreciate some ideas on my battery life in general, and what this issue is in particular.
Background:
- Horrible battery problems with my Sensation on stock Sense, Miui.us and now with HyperSensation ROM-CM7.1 with kernel faux123v0.2.3r.
- Been getting around 5-6 hours with normal use, no 3G, no wifi, no GPS, no Bluetooth, low screen brightness, etc etc.
- I also uninstalled Gallery as I was getting the sensor usage issue which I thought may be causing my battery woes, but no dice yet.
- I prefer to keep data on at all times (2G) as that's what I use my phone for, so I don't use this Juice Defender function.
Thanks,

How did you calibrate your battery? Did you..
Flash Rom
Kill battery to 0%
Charge fully 100% then wipe battery stats? Or did you wipe battery stats as you flashed? Thy could be a major problem
Also you have CPU your max set to 1.56ghz when its charged. That could cause the peak in usage. Especially if you have it set to performance and not ondemand. Those are the only two things that's really stand out to me.
Also check the arhd thread. In one of the last pages (depending on when you get this) there is a link for a fix on battery drain on fauxs latest kernel. Check it out
Thanks rddocke, I will check out the kernel fix. I did wipe, flash rom and reset the battery stats at the same time. I will definitely try your method, I didn't realise I had it upside-down.
As for the spikes, they seem to be continuing today, I can post screenshots later. Given that the major battery user is "Adnroid System", would this narrow my issue down to the built in apps?
On the plus side, with the new setup today on my 3rd battery cycle, I am getting better battery life than before aside from the spikes.
ya the spikes could be do to an auto update, maybe background sync... any things could cause it as long as it isnt a constant high usage i wouldnt worry about it. but if you want to help your situation i would set back my cpu max to 19200 when charging, and clock back to 1.2 for daily use, switch your goveners to ondemand and get them off performance.
basically whatever its doing at those times its running at the highest point your cpu can handle. adjusting wont solve your problem but it will reduce the amount of battery it uses
idk its hard to tell android system is always going to be the juicer, that and sense. nonsense for arhd could help you out too. i particularly like sense tho
hope i helped

I'll change these settings as well, great. I feel like I'm getting somewhere gradually, been spinning my wheels for a week on this.
I can't 'thank' you for some reason, but my buddy should have just done it, which is fair since I can finally pester him less about my battery problems and pester other XDA members instead!
No problem buddy glad I could give you some help. Let me know what you discover from all that. Another tip I could give is maybe test out a bricked kernel 1.4rs or 0.91 seem to be working best with sense 3.0 from what I've read
Hey guys,
I'm having trouble with the battery for my Galaxy S depleting really quickly (about 10% per hour).
I'm running ICS with teamhacksung's latest build (13) and platypus 3.08 NEO 3.0 kernel.
I thought initially that it was a kernel problem (I was running FUGU, which isn't on the preferred list of hacksung), so yesterday I wiped the whole thing, upgraded from build 12 to 13, flashed the kernel, wiped all of the caches and restarted.
The battery seemed fine and it decreased about 10% in 8 hours on standby, which is more than acceptable.
Then I was wokenup at 5 am by the phone telling me it needed charging (it had dropped 70%+ charge in 5 hours). By looking at the battery stats (attached below) it says that 70% of the battery is drawn by the OS, upon closer inspection it seems as though the system is draining when it becomes actives, and it looks as though it's becoming active on a regular interval. I thought this might be due to Appkiller, but I've since disabled it and it still seems to be draining pretty quickly.
The only other thing I can think of is that when I receive an email or sms, the settings and back buttons light up and stay on. Could that be the drain?
Anyone have an idea?
Thanks a mil
Cheers
Paul
Update: Swype to blame
Hi guys, I think I've solved it. If I don't post here again then I am right.
The problem is Swype. I installed it on ICS and it works great, but when I try to download additional languages, it seems to get stuck in a loop of attempting to download and failing. This results in the phone constantly being on and never going to sleep more which depletes the battery in a matter of hours, and of more than 170mb of mobile data raked up in a couple of days.
I haven't reinstalled Swype yet, I want to see if the battery lasts today before I do, but I will try to reinstall it without the additional languages and see if it works like that.
Cheers
Paul
Yes, confirmed, it was the installation of additional Languages in Swype.
Cheers
Thanks a lot for your question + solution. Using devil 1.1 kernel and Teamhacksung build v16 I had exactly the same problems. Now I removed Swype, which didn't want to download the Dutch language pack anyway.
I've been running TeamEOS on my Xoom for quite some time, and it's been great. However, recently the device's battery life has become incredibly poor. For example, today my Xoom has been unplugged for 8 hours 47 minutes, without being used at all, and the battery is at 61%.
Previously, the Battery usage settings view was showing the Wi-Fi in use all day, but today I turned Wi-Fi off and it is still the same. The 'GPS on' line shows one small section of blue (about 10 minutes) and the 'Awake' line shows a few times it has been awake, maybe half an hour in total.
I installed BetterBatteryStats and the longest Kernel Wakelock is PowerManagerService, for 2m 2s, the longest Partial Wakelock is ConnectivityService at 57s.
Under 'Other' it shows that the device was in Deep Sleep for 8h 39m.
Another odd thing is that when I first unplug the device, I get a kernel wakelock on cpcap_otg. If I don't do anything the battery drains even faster than it did today (it never goes into Deep Sleep), but if I plug in my USB card reader (without a card), and then unplug it again, that wakelock doesn't happen again, extending the battery life slightly.
I have a Wingray Xoom (MZ604), and I currently have TeamEOS nightly 114 installed. I have tried various nightlies, back as far as 90, and have also done a factory reset, to no avail. I haven't yet tried going back to Honeycomb, although maybe I should just to check, as it certainly used to work fine under TeamEOS 1.0.
Does anyone know anything else I can try to do to fix this?

Battery life seems to be so device specific that it's really difficult to diagnose, tho you seem to be looking in the right places. I'm on 114 as well and my battery life is fine...normal for my device, depending on use. It is said that you need to let a new rom install settle a bit, and I've been told to flash a new rom with a full charge...other than that, I don't know.
It could be some app you recently installed that wakes up your device wifi and consume battery. To diagnose more, get betterbatterystat app.

He said that is the app he is using. I'm sure, as you said, it is an app causing either wakelock or something syncing in background.
Are you syncing Facebook? I uninstalled the app a long time ago and battery life went up.
Tried wipe battery data in recovery? That may fix your battery issues.
kinda old thread, but if you are still facing battery problems, try this.
go to settings/wifi/advanced and choose never for "keep wifi on during sleep"
I had the exact same problem and it turned out that the device gets a wakeup call from the wifi router every now and then, which keeps it from entering deep sleep mode, resulting in horrible battery stats, running dry after about 1,5 days of just laying around.
Since I did the setting change, my xoom lasts for almost 1,5 weeks at light to medium use (mainly browsing and email) now

true, but don't forget that will also kill your apps from keeping their state up to date. email push won't work anymore. it's a matter of what you want, i personally rely on the phone for incoming mail and use the xoom for reading with disabled wifi during standby. it's the best of both worlds, instang notification and long battery.
oh, of course you´re right.
I didn´t thought that this could be an issue for other people.
Like you, I get my mails on phone and work on them on tablet.
Like you said,best of both worlds and feels so natural
But I still say, if you can sacrifice the "always-up-to-date" satus on your tab, just do it cause the battery uptime afterwards will be totaly awesome.
I know this comes up a lot but my issue is probably different than the common ones.
Data is only on when I intend to use it, the screen timeout is 5 seconds, the brightness is auto and mostly fairly dim unless I'm outdoors. I do run a couple monitoring apps (older version of system panel v1.08 and battery monitor widget pro).
Up until a few days ago, my phone could be left overnight and would only drop about 10%, if that. A/c charging took 2 hours going from about 10% to 100.
Now it takes at least 4 hours to charge, last night it dropped 50% or more in about 9 hours.
There's definitely something wrong here for it to have changed so drastically.
System panel shows which are the top cpu hogs for a given time frame but everything seems normal. System and system processes are at the top of the list, which is where they should be. I even put my phone I in airplane mode thinking maybe it was a signal issue but the battery still drained fairly steadily.
I've wiped the dvorak cache, battery stats, and even used sd maid to clean temp files / optimize dbs and stuff.
I recall installing one app (subsonic) around the time the issue started but I've uninstalled it to no avail. Fairly sure that was the only change I made around the same time, but I don't believe it is a stray app due to the cpu usage in system panel not being abnormal.
After a reboot the battery is fine for a while but the issue still comes back.
So, anything I'm missing? Any suggestions on how to go about diagnosing this issue?
I'd like to avoid formatting the phone if possible.
Thanks in advance.
Check wake locks

I've been doing some more research and came across an app called CPU Spy, it conveniently showed historical data since last boot (rebooted before I went to sleep) and the CPU was in Deep Sleep for the duration of the night, and I believe that would mean it's not a wakelock issue, right?
Pretty sure I've found the culprit. I forgot I updated the Facebook app recently so I uninstalled it this morning and the battery has been fine ever since.
Odd how it didn't use any cpu but still drained the battery fairly quickly. Perhaps some issue with the settings or something.

sorry bud but ur wrong. CPU Spy will report a deep sleep but if you still see such a massive drain clearly wake locks still exist. Better battery stats from the market will tell u what apps are keeping your phone awake.
and yeah, background syncing apps, if not configured properly, can take quite a bit of life
I have Samsung Galaxy Tab 7.7. When I bought it (close to a year ago), it came with Android 3.x.
For the first few days, battery life was horrible. It would only last 6 hours at most. I did some tweaking (don't remember what, maybe wi-fi and notifications) and everything started to work great. I had 50+ hours of idle/sleep uptime.
Last week, all of the sudden battery life degraded back to 6 hours at most. I'm sure I haven't made any config changes. Didn't install any new apps.
Once I realized the problem is back, I did "check for updates" and installed Android 4.0.4 hoping that it might fix the problem.
It didn't. The tab is only able to keep working for 6 hours or so when left completely idle. It also stays somewhat warm. It used to be completely cool when things worked right. It was also this warm in the very beginning (when I just got it and battery life was bad).
I checked all the threads I could find about battery drain, but nothing helps.
I disabled Google+ and Social Hub.
Disabled auto sync.
Tried all three different Wi-fi settings.
Deleted all widgets from the main page.
I'm attaching some screenshots:
- The battery screen after 1.5 hours of idling. Android OS is taking up most of the battery.
- Battery history showing that wifi was off, screen was off, it was awaking roughly one every half hour.
- CPU spy, showing that it wasn't in deep sleep as much as it should have been.But it was going into deep sleep, so wasn't prevented from sleeping like described in some reports.
-Wakelocks overview.
Can anybody help me figure our what's wrong? How can I find out which service is keeping the tab running?
It's not rooted, and I would like to keep it that way if possible.

I'll ask the mods to move it.
Use better battery stats xda version, better infos on wakelock
Uninstall all stockbloatware, latest ics 4.0.4 (spain version last time i check),
Uninstall apps you dont need. Something keep the tabs running. Most likely browser not finished loading tabs. Get stablewifi connection see if it helps
