I've been trying hard to avoid the Epic update, since my phone was working great. I was getting almost 20 hours battery before being asked to charge, using about 30 minutes phone calls, 1 hour "display on" time, bluetooth/wifi off, GPS only when needed.
The nagging update available message would always pop up, and I'd always tell it to install later.
Somehow, I must have accidentally selected update while getting out of the car today, since I saw the phone installing firmware and then reboot.
After the reboot, my Sprint Hotspot stopped working. Now when I activate it, it turns my 3G radio off. Prior to this, I could activate (and use) Sprint Wifi tethering even though I am not specifically subscribed to it. Now, it still "activates" but shuts down my data connection.
Even worse, when I try to activate 4G, it just hangs the phone. I tried factory resetting, which did not solve the problem. Still no more 4G. Also, I noticed my battery getting really hot, and the smell of smoke inside the case. The battery went from 50% to 9% within a minute!! I don't have any explanation on how the update caused this.....
This update fried my phone! I'm going to try the Odin method back to DG27. If that doesn't work, the phone is going back!
DO NOT UPDATE if you can avoid it!!
that sucks
I'm having a really really hard time believing the ota update had anything to do with anything you described.

Me too, but I don't know what else could have caused it. Just tried Odin, still can't get 4G to work.
I don't think there's much else I can try. The phone just hangs when I enable 4G. Tried factory reset, Odin back to DG27. No luck.
Any ideas?
Dont listen to this guy -- you want the DI07 update on your phone. It has vital improvements to the radio and kernel. It doesn't break 4G or ruin battery life.
it has happened to many of us,including me..i also started a thread in the development forum..i talked to a service rep and they instructed me to do a msl reset,which required a msl code the give and no luck..this happened to me last week.since then i swapped my phone for another unit an was weary of updaing again,but i did and everything works fine now.im guessing a bad batch of phones or bad dowload/install of update ota.return it for another

Before the update, I was getting about 14-15 hours of battery with my average daily use. After the update I'm swapping batteries every 6 or 7 hours. I started tracking power consumption a few days ago with Spare Parts. I flashed back to stock with odin, and installed the DI07 update. The only apps I installed were Battery Indicator Pro and Spare Parts. I noticed right away that the running time was always close to 100%. That means that the phone is not sleeping. Under "Partial Wake usage", Android System is running almost the same amount of time the phone is powered on. It's not spiking the CPU, but running just enough to create a partial wakelock. This behavior is consistent on every boot. Normally, Android System should only keep the system awake about 3 or 4 minutes per hour of uptime at most. I think they botched something in the update.
Tonight I reverted back to DG27 and the problem is now non-existent. I only have one Epic to test, so I'm curious to see if anyone else gets different results. If it's just my Epic, then I will be returning it for another.
Anyone feel like experimenting?
I'm going on 18 hours now since I reverted back to DG27 and I'm still on the same battery. I would be on my third battery right now if I was still running DI07. I don't think I'm gonna be updating till Sprint releases another fix. Other than Media Hub and the loss of battery life, I noticed no changes while running DI07.

I'm getting over 18hrs since update. It maybe just like the HTC phone when you flash the rom the battery life goes down for the first few full charges then after that it's fine. Maybe I'm just lucky because I'm not having all the drama you guys and others are having.

Any why should we listen to you? Can you describe your source of knowing how this update has "vital improvements" to the radio and kernal? What are the nature of these improvements?
Thanks
-Everyone
Not sure what the particular improvements are... but check your phone info and you will see that the baseband was changed, which means a new radio was implemented. Also, in the release notes it specified that there were some "Qualcomm Updates", and since Qualcomm engineers the radio in our phones, it doesn't take much brain capacity to put 2 and 2 together.
I've updated and have experienced none of these problems. (As I suspect is true of most of the people here.)

It ABSOLUTELY ruins battery life. If it doesn't ruin your battery life specifically, then your one lucky sun of gun. It cut my battery life in half. I used to be able to go to 11pm and never even get a battery warning! Now, my phone completely shuts down by late afternoon while I'm still at work. DI07 is a horrible update. I don't know what Samsung/Sprint did, but my screen is dimmer, battery life took a major dump, and the phone does not seem any faster, actually slower if anything. My phone also seems to be hot all the time, even after it's supposedly been asleep for hours. With DG27 it was always felt cool when pulling it out of my holster and not hot like it is now.
Testing...testing
After running DG27 for almost 24 hours with great results, I decided to give the DI07 update another shot. But first I made a Nandroid backup in CWM before I accepted the update. After about two hours on DI07, it was clear the phone was not sleeping again when the screen was off.
So now I'm gonna try another experiment. I've done a system restore from my Nandroid backup to DG27. Except that the Baseband(radio) is still DI07 because Nandroid doesn't touch the radio. I'm thinking that this will tell us if the new radio is the culprit, or if they just botched something in the DI07 ROM.
Dev's, let me know if I'm off base here. I will report as soon as I have any relevant results.

Heres what will help:
Run the root script, delete all sprint bloatware, and keep track of all the services running on your phone. I'm getting 20 hours of battery with heavy usage on the DI07 update.
Also, try the bump charging method which has helped me a lot. Turn the phone on, let it fully charge, unplug, let it fully charge, turn back on.. rinse and repeat. It helps.
The update is not what is causing bad battery life. The screen dimming is part of the auto-brightness setting and/or power saving setting which should be helping the battery more than killing it.
Get System Panel/spare parts or any kind of task manager to MONITOR (not kill) processes running on your phone.
Here's a post from another forum, so I'm not the only person with a dead 4G radio. I believe it was temporally related to the update, but reverting back to DG27 didn't fix it.
Link: http://forum.androidcentral.com/sprint-epic-4g/36985-4g-doesnt-work-after-di07-update.html
"I have been out of town in a non-4G area since applying the DI07 update. Got home earlier today and just went to turn on 4G and it no longer is working!!
When I enable 4G (through the pull-down or the settings menu) now it just says "On..." and then "Unknown..."
Anyone else that has applied the update and lives in a 4G area seeing similar behavior?? I am currently backing up me SMS messages so I can do a hard-reset to see if that will fix it."

Infamous,
These are all good suggestions for basic power management under normal circumstances, but for some reason this update has introduced an issue that causes the Android System process to prevent the phone from sleeping. Why it's not affecting everyone I don't know. Some people had to take their phones back to the Sprint store after the update because they got so hot and would not cool down unless turned off.
Anyway, if you are getting 20 hours on heavy use, you obviously don't have the bug. But to anyone who thinks they might, you can check using Spare Parts.
First, if you've just rebooted, turn the screen off and let it sit for a few minuets. Open Spare Parts and click Battery history. By default it displays 'Other usage'. If your 'Running' percentage is 100% or close to it, and your 'Screen on' percentage is anything other than your 'Running' percentage, then your phone is not sleeping when the screen is off.
Next change the top tab from 'Other usage' to 'Partial wake usage'. This will show you what is preventing it from sleeping. You can click on whatever is at the top of the list to see its partial wake time. If it's 'Android System', the partial wake time should not be any more than about 1 minute per hour of system uptime. For example, if your phone has only been on for 10 minuets, and 'Android System' has a partial wake time of 2 minutes, you have a problem.
Found more info here.

This is great info, according to Spare Parts and your info, I have a severe problem. I have just killed DRM
The update went through automatically Sat night, battery has dived at least
50%. Reboot at that time.
Battery History
Total in all Time Since Reboot (2 days)
Running 30.5% 99.7

I see the problem, don't know if DRM dead will fix, is there anything else I can do?
I am rooted (or at least I was, I stayed stock and added Wireless Tether, it is broken). So not happy there either.
I will charge and check this tomorrow to see what changes or if there are any other suggestions.
Thetwo apps running none stop are I! Agent Service in Android System and GTalkService in Goggle, using over 10 mb ram
Other usage is still almost 100%, Screen time has gone down, but Wifi On is same as Running and I have it turned off every which way I can find as with nothing showing on top bar.

I’m wondering if my phone or battery is defective. Up until about a month and a half ago, my hardware version 003 Evo used to sleep for 19-20 hours and have 89-91% charge left. I could easily get a full day (for me, 5:00 AM – 9:00 PM) with light to moderate use and still have plenty of charge left. I once got the warning at 15% charge at the end of a 3-hour + phone call and right at about the 20-hour mark. Then things changed.
I now have Azrael 2.1 DC installed with the Azreal Theme, animations, and wallpapers using stock HTC #11 kernel as distributed. The only things synching are Facebook for HTC Sense (synching contacts once a day), Google (normal), News (manual-synch only), Qik (disabled), and weather (every hour). The main Facebook app has everything unchecked and is not running.
I removed the big Favorites (people), Bookmarks, and Friend Stream widgets from the main screens.
The non-default items running has been reduced now to just a few items, but ones that I’ve used all along:
Brightness Toggle Widget, Dr Web Anti-Virus , Documents To Go, and Swype. (Note: Each of these has been through one or more updates since this all began.)
At the current time, if I take my phone off of the charger at 6:00 AM and maybe view/delete a few of the overnight SPAM email, by 8:00 AM (2-hours later) the charge is between 78-82%. If I make no calls or just spend a minute or two on the phone, view/delete 2-5 emails, maybe send a text or two and don’t charge it of course, by the time 5:00 PM rolls around the charge is down to 15-20%. Sometimes it’s less.
I powered on the screen just now and power was at 91%. I viewed two emails, deleting one, in about 30-seconds. Power now at 89%. The phone has been unplugged for 2-hours.
Since I bought SetCPU I installed that temporarily and verified that the CPU isn’t constantly running at 1GHz, but is scaling using On Demand.
Have made backups, tried different kernels, different ROMs (Sense and ASOP) and kernels…it’s all the same, more or less. To add more confusion, my wife’s Evo (completely stock) is now only getting slightly better battery life than mine. Our Evos were pre-ordered and shipped on release day. I’m wondering if either one or both of our phones is screwing up, using far too much power far to quickly, or if it’s the batteries…maybe a bad lot?
I’ve attached a screenshot of the SpareParts battery screen after a full charge. Can someone let me know if the voltage, etc, looks correct? I have several other screen caps showing various info that I can upload later that may help.
If anyone has heard anything that might help to explain this behavior I would greatly appreciate hearing it. Thank you for your time.
New observation. Put SetCPU back on my Evo, and just sat there and watched it for a while. I've observed that the CPU appears to alternate between 245MHz and 998MHz, spending more time at 998MHz than anything else.
I plugged in my Evo, set the screen to not shut off when plugged in, removed SetCPU, installed System Panel, and observed the CPU activity for about 20-minutes.
While the CPU load was very often in the 10-15% range with frequent brief visits to higher demand, the CPU Clock Speed never dropped below 661MHz during that entire 20-minutes and spent a lot of time all over the higher frequencies.
Tried killing everything that I could, even the things that restart; nothing made much difference. Going to wipe eveything, and try some different ROMs and see if I observe the same behavior.
4G may be running in background trying to connect and throwing log errors every 2 secs. Doesnt matter if you turned it off..it keeps going and is a know defect at medium level of support at google site and known for a few months.
Verify using aLogcat or other free log app.
Errors will look similar to
E/Wimax (***): <DC CONNECT> IO error: msg='/1270.1:7771 - Connection Refused'

and wont stop unless you reboot the phone after you use 4G.. every time.
Thank you for the reply! Unfortunately, I live in the Greater New Orleans, LA area, one of Sprint's red-headed step-children, where we will probably get 4G right after Tenney, MN gets it.
Last night, after a nand-backup, I wiped everything twice as usual, and install CM 6.1.1, the latest Google Apps, updated everything and built a normal installation. I left the kernel that it came with.
Using the default 'On Demand' CPU governer, once it settles down it does spend more time down at 245MHz, butif it rises at all, it prettymuch goes straight to 998MHz and back again. I set the governer to 'Conservative' and it appears to be working. The CPU does ramp up on occasion but does not necessarily immediately go all the way to 998MHz...in fact it rarely makes it to that speed.
I'll spend a bit of time like this and observe what sort of battery life I get. One odd thing...while sitting on the charger this morning, my Evo spontaniously rebooted itself...we'll see.
Thank you for your time.

I have been having the exact same problem with my 0003 phone with Nova screen. I used to get fantastic battery live. I would take it off the charger and it would sit at 100% for at least an hour. Nowadays, I take it off the charger and by the time it takes to get to work (10 mins) it will be around 92%. I have tried 3 different batteries, numerous ROMs and kernels with no changes. The only thing I can think of is that a month or 2 ago my daughter knocked my (naked aside from screen protector) phone off of the counter and it fell bottom left corner first onto the tile floor, cracking the screen. I actually went by the Sprint store yesterday and talked about getting the screen replaced. According to him, they don't have parts for the Evo so I am getting a new phone. Hopefully that takes care of my issue. I know that doesn't really help you but just wanted to let you know, I have the same issue
Thank you for your reply! I've been fortunate and have not dropped mine yet. Trying a new 3.70 ROM on my phone and have updated my wife's stock Evo to the same release. Going to observe whether or not this makes any difference.
try doing a full erase and wiping your battery stats (in recovery). see how that works for you.

Thank you for your input. When I created the ROM, I did a multiple complete wipe, and then started flashing. I recently redid everything again with Azrael X v3.0. After a few days, I recharged with the phone off for a few hours after the light was green, and then reset the battery stats. Unfortunately, no change resulted.
I recently flashed the "SBC-net-4.1.9.1-more-havs-v7" kernel, and this has had an effect. When I remove the phone from the charger, usage starts there instead of zooming down to the 88%-92% range. I've disconnected from the charger, and made a short 2-3 minute phone call, and it was still at 100%!
I've charged the phone for a few hours after the light was green, and then again reset the battery stats (though the post for the SBC kernels says that since the battery gets and stays fully charged, no more need to reset the stats).
I am strongly suspecting that the battery is the problem. In order to test this I've ordered a 3500 mah battery. Once I have it installed, I'll fully charge, and then use/charge for several days. I'll observe the battery life during this part, but will then flash to a rooted, but otherwise completely stock ROM, and live with that long enough to observe accurate battery usage.
I'll use the info that I gather during that time to compare with others with the same type of battery. This isn't an exact science of course, but If they get a full day with very heavy usage and I get a full day with little to no usage, I know that my phone is borked, etc.
Thank you for your time, and Happy New Year to everyone!
Well, have had the 3500mAh battery for a while and its not the battery. I am totally baffled. The phone hasn't been dropped, there's not a blemish on it anywhere. Absolutely everything works, there's no 100% wake time...the up time and awake times are different and at least appear to be reasonable.
Both regular and extended batteries have been through the HTC-recommended 'conditioning' procedure, or whatever they call it. I've tried several different Sense ROMs as well as CM6-6.1 (doing double and triple wipes of everything), with various kernels...stock, custom, SBC, non-SBC, HAVs, noHAVs, more aggressive/less aggressive/no undervolting, TM, King's (always wiping cache and dalvik). They don't all run the same, but regardless of what ROM or kernel I have installed, after charging all night I can unplug the phone and leave the house at 6:00 AM, not use the phone at all...100% screen-off time, and by 3-ish in the afternoon the stock battery is at 35-40%. Awake time could be anything from 45-mins to a little over an hour.
Previous to this, and whatever switch got thrown that's causing this, after that same 9-hours of non-use the stock battery would be at least 90%...maybe 85% on a weird day.
With the same 3500mAh battery that others get through 12-hours of extremely heavy use, or with casual use go a few days on, I can use it to maybe answer a couple of texts, quickly view and delete a few emails, manually killing the screen after any activity, and by 5:00 PM, 11-hours later, I'm looking at 40% charge.
The only suggestion that anyone has had (in another forum) was to download the original signed RUU, run it taking the phone completely back to original state, update it OTA, and then re-root (hboot 2.10 with Unrevoked 3.31 or whatever it is, latest RA, etc). The theory is that 'sometimes using the RUU and going completely back to stock is the only thing that fixes some issues'. Has anyone else ever heard of anything like that?
If anyone can shed any light on this in any way, shape or form, you have my sincere thanks in advance.
Thank you for your time.

A lot of times its a market app that's the culprit. Make sure you don't have an app installed that keeps your phone awake even when the screen is off. The market tells you what every program has access to including wake issues. After a fresh Rom install / kernel flash........check all apps to make sure none of em do this. Task killers are not the answer......not installing apps with too many permissions helps a ton.

I got the same story from the sprint repair center by me as well. When they told me new phone I asked them "do you mean a referb" they said "yes". I'd rather have my screen replaced then get a referb
Thank you for your reply. Yep, I stopped using task killers of any type when froyo was released due to OS functionality making them useless, and if fact a negative.
So far I haven't experienced any extreme wake-time issues, though I knwo they can be a big problem.
I've tested this by completely wiping everything several times, flashing a ROM and not making any changes so its still using the factory HTC #15 kernel which is pretty well known now for good battery life. I've run it like that for a week with multiple restarts, full charges with battery stat wipes, etc.
So far, no luck, no change. Still hoping to figure it out.
Problem Identified but not yet resolved.
It appears that there is some issue with one or more radios in my phone. I don't know enough about the innerds to know if there is more than one, but whatever receives data downstream is screwed up.
Over time I've noticed that my downstream data has gotten slower and slower. Then I started missing calls periodically, and texts sent to me at 10:30 AM were showing up as arriving at 6:30 PM...weird stuff.
After un-rooting, performing a complete factory reset, and a complete data restore (from the ##3282# menu), the phone and texts seem to be more consistant, but running the SpeedTest app to a server here in NOLA produces the following results:
Ping: 20ms - 30ms
Downstream: 0 - 128Kbs (Seriously, I get "0" often, and 128Kbs is the absolute max achieved on occasion)
Upstream: 1.2Mb - 1.46Mb
After re-rooting the phone, I've tested this in the Azrael 4.0 and EViO 1.8 Sense ROMs, and in CM6.12, and the results are identical. Its very strange that it only seems to affect the downstream rate.
I guess its time to RUU, bring it to a Sprint store, pay their $35 and see if they can fix it.
This is my first android phone and I'm wondering if I am doing anything wrong. Yesterday I charged my phone and it was at 83%. I unplugged the phone and went to sleep, when I woke up this morning the battery was completely drained.
This happens a lot. Even if I am not doing anything it still drains like crazy. I just text, make some phone calls and it barely makes it through the day. I don't play any games, no gps, no Bluetooth or anything. With my plan, I don't have a data connection so I can't connect to 3g/4g so that shouldn't drain anything.
What could I be doing wrong? When I'm done using the phone I tap the power button on top, the screen goes black - to sleep I presume and I put it away. I had an iphone before this and I did exactly the same thing and the battery lasted for 3-4 days on one charge.
Whenever I see what's using up the battery, the display tops the list. The display is using up 75-80% of the battery. If the phone is asleep for most of the time why is the display using up that much battery? Am I not putting the phone to sleep correctly?

What could I be doing wrong? When I'm done using the phone I tap the power button on top, the screen goes black - to sleep I presume and I put it away. I had an iphone before this and I did exactly the same thing and the battery lasted for 3-4 days on one charge.
Whenever I see what's using up the battery, the display tops the list. The display is using up 75-80% of the battery. If the phone is asleep for most of the time why is the display using up that much battery? Am I not putting the phone to sleep correctly?

If you cant connect to 3g/4g, you should turn it off in settings. Otherwise, Your phone will constantly look for a signal, draining your battery.
Battery life is all relative. Every single person will experience different battery life. The apps you have installed, the amount of time you spend on it and the time you spend on/in each app, distance from cell towers, distance from Wi-Fi sources, settings you have for every app and things like sync and what not.
The first thing to check is if your phone is being affected by the init or suspend bugs. The good news is the former has an easy fix, and the latter can be temporarily fixed by a reboot.
First, download & install Watchdog Lite from the market. Then open its preferences and check "include phone processes," "monitor phone processes," and "display all phone processes." Then just use your phone as normal. It may take a while before you get an alert from Watchdog (and maybe you never will and it ends up you have a different problem). But if you do, note the process that is the culprit.
If it is the init process, go to settings>applications>development> check "usb debugging."
If it is the suspend process, reboot the phone. It should keep it from happening again for a while.
I know the second answer isn't really an answer, but so far it's all we've got for that problem. There is more information on the 2 problems in these threads:

Good luck...I had both of the problems and my phone didn't last to dinner time. Now I get better battery life than the iphone 3GS I had before this...about a day and a half of moderate use.
EDIT: also you'll probably want to go to settings>wireless & networks>uncheck "mobile network" since you don't have a data plan. No reason to have that on since you don't have a data plan.

I installed this using the Moderate setting, and then selected those options as recommended in preferences.
Does Watchdog use a lot of system resources when running in this manner? Will it cause the battery to drain noticeably faster?

Completely unnoticeable, IMO.
I installed watchdog lite and I have had couple of alerts. I got suspended couple of times and I also got Android system once.
Android system - 50.1%
Foreground
Suspend - 54.4%
Linux Process
I turned off the data usage from the settings and it did help save battery. The display is not using so much battery life anymore. It went from using 70% to 35%.
Edit: Battsatt reported that the battery was at 93%. When I saw the two alerts above I rebooted the phone and Battsatt now starts reporting the phone is fully charged.
Make sure the GPS is turned Off, too...
All these answers and the easy ones were not mentioned..
Make sure you shut your AUTO SYNC off...
Make sure you lower your brightneess....
Make sure you turn off GPS(was stated above me)
Turn off your wifi if you are not using it.. make sure you are not transmitting your hot spot stuff...

You just summed it up right there. You are experiencing the 'suspend' issue, period. There is no app you can install to fix it. There is no app you can uninstall to fix it. There is no setting you can adjust to fix it. There is no fix for the 'suspend' issue, literally.
I started the following thread in an attempt to consolidate posts and hopefully work toward flushing out what the real issue is...
http://forum.xda-developers.com/showthread.php?t=872839
This is a real, legitimate issue with Android 2.2.x Froyo. As I linked in my post, this is Issue # 11126 on Google Code...
http://code.google.com/p/android/issues/detail?id=11126
If there was an app or setting that fixed the 'suspend' issue, we wouldn't even be discussing this right now. There are fixes/workarounds for a lot of things, but right now, the 'suspend' process issue truly is a mystery. No one, not a single person has yet to post, "this is the cause of the issue," let alone a fix for it.
I wish you had a fix man, I really do. My fiancee experiences this and there's only one way she's found to sort of workaround it, sort of - she reboots her phone every morning. This seems to keep it at bay, at least more so than when she doesn't reboot each morning, once she takes it off the charger. She still gets it though and she's just used to looking for Watchdog and checking her processes now.
This thread could go on and on forever but it comes down to this:
- The MT4G does not have insane battery drain and will give you about 12 hours of life, under normal>medium usage. If your battery is draining insanely quickly AND if you're seeing the suspend process jacked up so high, then there.is.no.fix.yet.
There might be a ton of other replies after this about uninstall this, install that, change this, don't use widgets, use widgets, etc. Those attempts will be futile.
The last couple of weeks my Focus started just eating its battery. Until recently I would be around 50% by the end of the day with light usage. Obviously less if I use it a lot.
But in the last couple of weeks, its just started sucking the battery down. I don't have push email enabled. In troubleshooting I even turned off wifi, 3g and bt. That helps but its still basically dead by the evening on days when I've made a couple of calls and thats about it.
I had AT&T send me a new battery and that made no difference. I flashed to nodo hoping that new firmware would help. Same thing.
I know I should factory reset it, but I don't think I'll be able to jailbreak it again if I do a hard reset with nodo.
Any ideas?
After soft resetting the phone defaults to enabling feedback in the settings menu. I would toggle it off and see if that is draining. I have noticed dramatic battery drain from that. Also, turn off the phone update settings. In the find my phone setting toggle the get results faster to off. You said you don't have push email but if you do have any emails on the phone just double check the settings to make sure.
Thanks for the reply. I do have feedback disabled and have checked and double checked email push.
I've had this thing since they first came out and have a pretty good idea of how the battery holds up and how different things affect it. That's why this is so odd. It using the battery like I'm playing video games or web surfing all day. The problem now is that when I do actually need to use the thing more when I'm on the road, its dead in a few hours.
I know this issue has been posted in forums for other devices, but I haven't seen anything about it for NC. I did try to search the NC forums but couldn't find anything that seemed to address this problem.
I am using MIUI 1.7.22. I have noticed significant battery drain due to Android OS (in battery stats), suspend (in the systempanel app), and event/o (also in systempanel). I have disabled auto-sync and any apps that appear to be likely culprits (those that might attempt to download data). This problem seems to appear with wifi on or off, and when on, I have tried both setting it to never turn off and to turn off when the screen is off. Initially I was experiencing battery drain due to cell standby, which I took care of by disabling the telephony provider, phone, and mms apks. I know many don't believe this has an effect, but I did it anyway. The cell standby drain is gone, but now I'm fighting the drain due to these other factors. Has anyone found a fix for this?
After scouting around for info, I have tried some suggestions seen elsewhere: rebooting and wiping dalvik cache. So far today I haven't had any Android OS, etc. issues. Standby life with screen off is as it should be (for now and hopefully forever)--very slow battery drain.
This is with wifi set to never shut off, which I prefer.
Suspend etc. came back last night although not as extreme as before. Hopefully some other folks will have things to add to this thread. I will continue posting progress info as I learn more about this.
From the code.google.com forums:
Confirm heavy battery drain with enabled Location & Security -> Use wireless networks / Use GPS satellites. I've disable both options and now my battery life is normal.
With enabled "Location & Security" options battery eaten by "Android OS" process (about 40-55%).
I will try this and report back.
Disabling WIFI and GPS in location/security had no effect. There appears to be a google process that prevents the system from sleeping.
I was still experiencing random battery drain due to Android OS, suspend, event/0 after switching to cm7. One suggestion I read was to disable calendar sync, as this appears to be a runaway process that attempts to connect to the server constantly without allowing the device to sleep. Doing this allowed me to get through the night with very little drain and the Android OS, etc. processes were finally behaving (within normal limits).
I'm not sure if anyone is reading this thread but I will continue to update until I figure out the solution, as I imagine this problem will become more noticeable to others who are equally frustrated with this issue.
Having same problems on my galaxy s2. Lots of people have this problem and think it's a problem with the os. What os version are you using?

Right now I'm using cm7 (2.3.5) but I was using MIUI before. Turning off calendar sync has worked well so far.
I had bad battery drain in the past and no deep sleep. but what worked for me was not to use any live wall paper. this fixed my deep sleep issues. for the battery drain, re-set your battery stats and re boot a couple of times for the stats to settle down. also check google map and latitude. in latitude just log out. un-checking sync in my yahoo email app also helped with my battery drain. my wifi is set at, off with screen. I went from 20 -30% drain in 7hrs to now 1-3% in 7hrs
I hope any of this info can help

Thank you, boxcar. I had tried all of those things (froze live wallpaper, reset battery stats, reboot, froze maps and latitude) but the only thing that worked for me was unchecking the box for calendar sync. Email sync and wifi appear to be non-issues--no difference between off or on. Evidently this google calendar sync bug is a known issue (that very few people seem to know about!). I hope google will fix this soon.
I also have same problem on my Galaxy S2. These two(events/0, suspend) drain many battery, 14% one night, without WIFI, GPS, Bluetooth.
I'll keep on tracing this issue, and share the result in this thread.

Turning off autosync seems to help the most (although setting WIFI to turn off when the screen turns off appears to help, as well). I tried using an autosync toggle but just turning it on at all seemed to result in a gradual creeping up of the Android OS, etc. problems. Manual sync of calendar and perhaps gmail and contacts seems to be the way to go. For some reason, exchange mail set to push results in no problems. The other trick I've found is to go to applications, then calendar and calendar storage, and force stop, delete cache, and THEN manual sync of calendar (reboot, recovery, wipe dalvik, fix permissions are good ideas, too). When I flash nightlies, I go through this process and the offending processes work as they should. If I don't, problems appear sooner or later.
I've had my nook on for 9 hours now, WIFI on (off with screen off) and 30 minutes of display on time. I've lost 9%, so I think I'm on the right track. This is how it should work, I.think. Of course, the results SHOULD be the same with autosync on, but manual sync for good battery life is an acceptable small tradeoff in my opinion.

For the noobs in the audience, how exactly does one turn off autosync? Where is it located?
Thanks in advance.

Menu, settings, accounts and sync (I leave background data checked).
I found part of the root cause, maybe some old application - can work on new version, but drain many battery. Today I uninstalled the 'Android photo widget', then only 1% battery has been drained within 2 hours when standby. Not totally solved the issue, but seems OK.
I guess you can also try this, find another 'bad' application which drains your battery.
Well guys, I'm not sure if I'm the last Nook Color user to continue fighting with this super annoying headache (I know SGS2 users are, too), but I think I'm on to something. I thought calendar sync was the culprit (and perhaps it was), but the Android OS drain (featuring nemeses suspend and event/0) would not go away and the arrival of this problem continued to be (apparently) random. I had an idea that, if the calendar sync kept alternating between suspend and event/0, perhaps this was due to old events that caused the sync process to continue longer than it would normally. So, based on this idea and logic, I changed my exchange e-mail account settings to sync email from the last month rather than to sync all mail. Looking at my work e-mail history, I realized I had e-mails in various folders and sent mail from as far back as 2001! Although it's nice to be able to access all e-mail history, perhaps the polling services were constantly monitoring the activity of super old emails and folders, which caused the suspend and event/0 processes to flip out. I don't know if this is the way Android actually works but it seemed logical to me. Well, for the last 24 hours, I have intermittently checked my cpu activity through systempanel, and what do you know, when the device is not being used, suspend and event/0 work as they are supposed to and Android OS stays low in the battery % list. PLEASE let this be the fix! I know there are other factors that contribute to the acting out of these processes, but on a stripped down device with no autosync or widgets and no out of control services identified in systempanel or watchdog, there can't be many other explanations. I'm curious if others with this problem have similar settings on their email accounts. In all the forums on different sites (and I've read a ton of them), I've never seen anything like this mentioned.

Please vote there, and, may be, Google will fix it.
For those still following this thread, here's a tip. Use Gemini app manager (in the market). This has been one of the best tools I've found for managing wakelock issues and battery drain during standby. It allows you to identify apps that start up on their own (more than you think) and prevent them from starting randomly. In my experience this has been a huge cause of the standby drain problem showing up as Android OS, suspend, and event/0 in battery monitors. I'm currently sitting on 81% battery remaining with over 1 hour of screen time after 21 hours since my last charge. I know it's not a lot of usage but it's the standby time that's fantastic.

I've a Galaxy S2. Tried everything, except disable autosync. Was losing 30-40% battery at night. So far since turning off google sync I'm getting about <1% battery use an hour. Will see if it continues. Thanks.
