[Q] A500 constantly waking itself - Acer Iconia A500

Anyone have this problem? My iconia a500 constantly wakes itself up for no reason. Doesn't matter what ROM or kernel, it happens all the time and destroys my battery life because the screen will stay on overnight. I'm afraid it might be a hardware problem :/

No one else has this issue? :/

Shouldn't be a hardware issue, as something (an app) is causing the display to wake. Think about it for a minute. When hardware fails, it doesn't work, or it gets warm enough, then fails.
So something is telling the display to come on.
Do you have a 500 or a 501?
Which rom/kernel combo?
I'll give a few pieces of advice.
1. Check the display time-out in the settings. Make sure it's not set to "never"
2. Set your wireless to sleep.
3. Uninstall any utility apps (task managers, battery monitors, display enhancements, etc) Anything that "might" cause the display to become active.
4. Turn off notifications and sync's. You can do this for a day and see what happens.
If that doesn't fix the issue, it could also be the fact that the rom wasn't flashed properly. Before you get into a defensive posture let me explain.
When we flash multiple roms/kernels, eventually some code doesn't get wiped fully by just doing the normal 3 wipes. Sure, half the time we can get away with it, depending on what rom we decide to flash.
The next thing we know, some strange things start happening. Usually small things. Like messages that say to insert sim card on a 500 (leftover build.prop from a previous rom). GPS is weak, wifi disconnects, etc.
The proper way to fully get rid of everything is;
1. Do the 3 normal wipes (user, data, and dalvik)
2. Go to Mounts, and do a format on those 3, and also Flexrom.
This ensures there is absolutely nothing internal left. Clean as a whistle.
Then and only then, go back to the main menu, and flash the rom.
As with kernels, never flash a rom and the kernel at the same time. Always reboot after the rom flash, do your setup, then reboot and flash the kernel. And make sure the kernel is fully compatible with the rom.
As I said, whatever it is, it's software related. Install minimum apps, and run it for awhile. Then a couple more apps, till you figure out what causes the display to wake and stay active.

I remember reading something about this from ACER in one of their release notes. They patched it. Because you're running a custom ROM, the patch must be in the boot or something else that typically isn't touched by a custom ROM.

[Q] Spare Parts

In my spare parts, it says my phone has been running 99.9% of the time. That means it isnt sleeping right? and that its eating my battery?
That sounds like the case
Yes and also using spare parts you should be able to find out what is running to make your phone not sleep. There must be a process that is going runaway and not letting it go into sleep even though the screen is off.
Using Spare Parts, check Partial Wake Usage. That will tell you what is keeping your Epic awake when the screen is off. Chances are it's Android System, which could be any one of 20 different processes. Spare Parts won't narrow it down to which on it is.
I was having this issue with DI07, but DI18 seemed to fix it until yesterday when I flashed from Andromeda kernel to Mixup with Voodo. It ran great on first boot, but then I swapped batteries and the no sleep issue was back. So I flashed back to Andromeda and the no sleep issue was still there. I did a system restore using clockwork and that seemed to work for a couple boots, but then the issue was back again.
Just now I flashed the DI18 stock tar with odin and restored my date from a backup. So far, so good. I'm thinking it might have something to do with one of the system apps I deleted. The only ones I removed were Amazon, SFL, Nascar, and the 3 DRM processes.
Just a general kernel flashing question for anyone who might know, should we wipe the cache or clear dalvik cache when switching kernels with clockwork?
I use Autostarts and I noticed that there are a lot of processes that are triggered by different actions. For instance, when there is a change in connectivity things like Amazon Mp3 and Media Hub are started. There are many other instances that I believe are unnecessary and I stopped them from restarting with this app. I don't know what the ultimate culprit is as far as battery drain but I know that you have to be extremely vigilant in order to maximize battery life. It seems to be an unfortunate side effect of having such a high power device. Anything that is starting and using mobile data is going to drain battery and has to be watched carefully. That's the price we pay for having our Facebook and weather feeds constantly updated on our homescreen.

[q] a few questions (battery, missing market, fc youtube)

sorry if some of these questions have already been asked and answered. unfortunantely, my computer crashed due to a manufacturing flaw so I can only access google and this forum via my epic (which can be a pain sometimes). also, since heros threads are always deleted, I cannot ask these questions there. please, any feedback and help would greatly appreciated.
okay so I reflashed backed snack 1.6 w/ ultimate after testing some of the newest froyo builds. id rather wat until I get the official ota upgrade.
after reflashing 1.6 for some reason, android market doesn't appear to be installed. where can I download the application? I even tried reflashing 1.6 over itself but that didn't work.
also, I'm using the new gingerbread youtube but I signed in and now I get a constant fc when I try to open it. how can I fix this? if I can't, where can I download an earlier version of youtube?
another question. this time about battery. using 1.6 w/ ultimate, I get fairly decent battery. only problem is, my battery stats say that my display and standby are what is killing my battery the most. nothing ever runs in the background, every so often I unlock my phone to either check the time or texts or facebook real quick, brightness is on its lowest setting, silent mode, juicedefender running correctly (battery life: x1.56), no data running in the background, drm killed, battery calibrated and battery stats wiped, and everything else possible to to save battery.
and something I'm noticing now that the phone is charging, the battery is quite hot and I'm not even using the phone. it only overheats when its charging and I've also noticed that its only hot when I use certain roms/kernels. any insight on this issue? any way to monitor and regulate temperature?
once again, any help would be appreciated!

Ill take a stab at these. Reason for you market not showing, can't say? Did you wipe 3 times before flashing bs 1.6?
Also never sign in on gingerbread youtube on 2.1 build. I don't think anyone has got that working yet. Simply clear the cache for youtube and you should be set.
Lastly, I don't know what to say about your bettery.. what do you have setcpu running at? Do you have profiles to lower your phones speed when in standby? Couldn't hurt to give it a shot.
Sorry about your computer, all my info is based on personal experience don't really have a "dev" type answer for ya. But hope some of this helps.
Goodluck!

thank you for your reply.
yes I did wipe both data, cache, and davlik 3 times. I guess I will do that now and report back.
how would I go about clearing the cache for one specific app? I know I can do that when I open up my settings and go to app development but youtube doesn't show up in that list.
setpcu is oc at 1300 and uc at 200 conservative. profiles are as follows:
charging/full - 1000 and 200 conservative
battery < 15% - 800 and 400 conservative
screen off - 600 and 400 conservative
yeah, brand new computer too. all of a sudden it couldn't recognize the hard drive. and yes, most of my info is based on personal experience and creeping on forums.
edit: wiped everything 3 times and reflashed. market till not appear.

For youtube I just open it up without a data connection and step through the process of signing out only enabling data when needed.
If you're missing market then you need to flash back stock with odin then start fresh. Baked doesn't remove market at all. If anything it's the fastest responding market I've used.
Heat from the battery is usually caused by programs requesting cycles or data. Just restart the phone before bed after your initial battery calibration.

as I stated, I have no computer at the moment. so using odin to go back to stock is out of the question as of now. hopefully there's got to be another way without using odin. if not then I suppose I'm stuck in this predicament until I get my computer back from geek squad. and yes, I've never had a problem with heroes work before. but for some reason, this is happening.
and as I've stated before, no programs or data run in the background on my phone. after initial calibration I rebooted it. and after every boot, I toggle airplane mode on and then off. ill continue to moniter battery temps and see if the problem persists.

Sorry bout that, I did read over that you hadn't had a computer. I overlooked it though. It just sounds like you might have somehow of gotten a corrupt install somehow.
Maybe you can try reinstalling 1.6 over top of itself. I don't really see anything wrong with that, but as stated before though. Make sure you wipe cache and dalvichk 3 times each before you do so.

Alliance 7.7

OK, so I'm a noob (to evo) and can't post on the dev thread for the Alliance 7.7 ROM so I'm going to throw this out here and hope for a response.
I tried RLS1 and didn't like it, there was some functions that irritated me so I went back to 7.7.
I like 7.7, I've got it stable, no sense reloads and I love the functionality.
However, my battery life is atrocious!!! I thought this was supposed to help save batt life??? I burned about 50% batt life in less than 3 hours in sleep mode!??
What did I do wrong??
I've been experimenting with Task Killer, Juice Defender and other supposedly power "saving" apps and settings but I haven't found the "holy grail" yet.
I'd really like someone to point me in the right direction if at all possible..Thanks!
Did you try calibrating your battery when you first flashed the rom?
Try downloading the battery calibration app by nema from the market.
https://market.android.com/details?id=com.nema.batterycalibration
What PRI do u have? If you go into settings and about phone (I'm not exactly sure if that's the correct path) it should tell you. If your running something newer than 1.77 some phones have a wake issue where it wont let the phone sleep with newer PRI's. Try downgrading to 1.77, the wake issue should then be gone.
You can get PRI 1.77 from here just make sure you backup your WiMax keys before you flash, you know just in case something goes wrong. : http://forum.xda-developers.com/showthread.php?t=715485
Maybe its one of the apps that your using that's not letting your phone sleep hence your battery drain. Spare parts on the market should show you if any apps are keeping your phone awake.
https://market.android.com/details?id=com.androidapps.spare_parts
Or your battery is going bad? I was having such horrible battery life with my Evo that after a while it just couldn't hold a charge anymore. I purchased a new one and all is well now.
Try an AOSP rom? AOSP roms tend to have better battery life than Sense roms. They don't have many services running in the background eating up memory.
I can't think of anything else anymore but hope this helps!

Our of stupidity but, how exactly can you back up your WiMax Keys? Where can you go? Lol sorry, feel free to troll on me for asking that

Lol Oh no none of that. I don't troll on anyone for not knowing something, we've all been there. Are you using amon ra recovery 2.3? If so, boot into recovery, go to backup/restore, nandroid backup and then it'll give u a list of things you might want to select to backup. Just unselect everything, select wimax and then select perform backup. It should take a couple of mins and then your done.
Actually I'm using ClockWork Mod 2.6 just seemed easier to me than AmonRa. (weird I know). but ok, nand back up and just select the WiMax info??
Also, v7.7 had an undervolt script built into it that some phones, mine included don't like. Might try flashing alliance rls2. Had the script removed.

thanks for the info, I think the battery calibration helped a little, only 30% depleted after about 8 hours with moderate use.
I found I do have a newer PRI, version 1.90_003
Before I go messing with it, what is the PRI and what does it do?

one of the reasons I didn't like RLS1 was the way they had the personalize button set to open the Kingsrom website. Did they change that, or is there a way to change it?
oi, I had things going pretty well with 7.7 but it started getting glitchy and slow. Don't know why because once I had everything running smooth I didn't mess with it anymore. Reboot helped for a little while but started glitching again shortly after.
I decided to go to RLS2, it's running smooth but my lockscreen shortcuts have dissapeared and I can't get them back, any ideas on that??

You might try going into your personalize settings and select a different lock screen, I know there are a couple that take that certain option away LOL I use the weather one with the app selector or the wallpaper with the app selector. Hope it helps

no good, lock screen isn't displaying the way it should, tried several and nothing changes.
Did a factory reset and the lock screen is working correctly again. There must have been something that glitched when I restored my settings.
Tried restoring my backups and it the lock screen isn't right again. So I guess I either live with it or start from scratch again..

Media service pins cpu

I noticed that sometimes service "media " start saturating CPU and everything gets a lag again, until I kill it.
Is there a work around for this? What is this service?
This behavior is consistent between both Overcome and Tasks ROMs, which makes me think it is a honeycomb's thing. It is possible that it is also something that pershoot's kernel entails, as I mostly tested with it.
But I did setups to wipe all, data, cache, dalvik, and yet the issue persists.
Thanks in advance.

it is an android issue. been around for a while, altho seems to be quite bad in TW. rarely ever happened in 3.1 vanilla.
you can flash 'watch media', which will kill android.process.media automatically, if it gets out of hand.
you can find this on droidbasement or the dev section.
Thank you very much, sir.

I had this problem with stock KG9 firmware. After i updated to latest firmware the problem is gone.
I have the same issue. From what I can tell:
1. try just killing the process. It'll probably come back though soon.
2. go to "Manage applications" and "Clear data" on Media Storage. This will help but sooner or later, it seems to come back again.
3. there is a problem with one of your media files. Not sure if it is pics, vids, mp3s, ringtones... but some file is causing this problem. The hard part is finding which one is the culprit.
I too have this problem
battery drain seems to be higher with screen off but still OK but with screen on it drains alot... lost 9% in the past hour before I decided to kill it
sometimes I see "DRM protected" something, and then "Downloads" something and "Media" in OS Monitor
I did a factory wipe thinking there was something wrong... it was fine at first but got worst gradually

Questions about standby mode

I may have asked this before, but I'm not sure.
My A500 has a custom ROM on it, but its had this problem on multiple roms. I haven't tried on stock yet, but that's probably my next step. Anyways, here are my questions:
- How long can you usually leave your A500 in standby mode and still wake it up?
- Is there a way to manually put the tablet into sleep mode?
When I first got it, I remember leaving my A500 in standby mode (it should automatically go into standby when you idle, right?) and being able to wake it by hitting the power button almost a day later. Now I can only do it for a few hours and then it won't come out of sleep. I'll have to turn it off by holding the power button down (even though there is no indication that it is turning off), then I can turn it on again. Sometimes my battery will be depleted, apparently indicating that it did not properly go into sleep mode?

Usually I can leave it in sleep mode for well over a day, and it still wakes.
Press the PWR button will put it to sleep.
I would guess, the problem is Kernel related. This sometimes happens with kernels that supply Over/Under voltage. Usually for overclocking. Most of the newer kernels walk a fine line with trying to get maximum battery life, and your tab may suffer "the sleep of death" and require a hard re-boot.
I would advise one of the older kernels, like RTrips 3.4+ or Thors 3.7. Try to stay away from the most recent kernels.
Also, a few of the custom 500 roms, are really "cooked". Lots of changes to the rom itself.
You may want to try a lightly stock rom with a lower version kernel. This will fix the sleep of death issue.
As with your battery, the usual stuff like wifi/gps on, notifications, syncs, these all cause battery drain.
I leave my wifi on, but my syncs are set to every hour. Mail, Sms, and FB (silent). GPS is hard set to off. Widget refreshes also are 4 hrs.
I lose maybe 6% or so overnight.
All of the above is true there is one more issue that can occur . Google backup and restore.a bad app that you keep getting restored by the above.
if all else fails you can try the fallowing..
download a near stock rom.. with STOCK Kernel .
in cwm
of course wipe all
format all..
flash rom..
wipe all again.. (you know all of that)
if im having a app issue.. to find the app.
when your tablet boots the first time.. when you get to setting up your google account.. untick the boxes for backup and restore of data.. then install your apps one at a time back . to see what app is causing the trouble.. Of COURSE this all only applies if the rom flash does not work.. google often puts the problem back.. Ti backup will do the same .. put issues back.. Trial and Error is only way to solve this issue. ITS THE ONE MOST COMMON AND MOST TALKED ABOUT ISSUE WITH not only our tablet but all of android devices..
GOOD LUCK ..

Thanks to both of you. I needed reassurance that my tablet wasn't just messed up. I have a warranty on it and was thinking about getting it replaced and seeing how the new one behaved, but I'll try the suggestions. I'll probably try to reload my ROM after formatting and start with just the base apps and add one at a time as you suggested. If that doesn't work, I'll try a different kernel or ROM with a different kernel. I've already tried not using SetCPU to under/overclock, but that didn't work. Thanks again!
Another (relatively rare) issue is that the kernel you're using actually is flawed and fails to wake the GPU after it went to sleep (this may be a lot later than the device itself, depending on background services!). In this case using a different kernel will solve the issue (stock kernel is works).
EDIT: Posted at the same time... By all means try another kernel, this is a known evil with custom ones.
Okay, so I've tried installing the stock, rooted 3.2 ROM which uses the stock kernel. Did not restore any apps from Google Backup. Still getting the same issue. Does this point to a hardware issue? I have a warranty on this tablet, so I want to know if I should try trading it in.
OK, before you take your tab back, personally, I wouldn't worry about it.
I have noticed, on some occassions, (yes, I do run stock rooted on occasion), that sometimes, the tab will get what we call the sleep of death. And usually, this may occur over a long period of time. Also, sometimes, I have to hit the pwr button several times, before it wakes.
+1 with the PP on overclocked kernels. This happens with the most recent ones.
Fortunately, System Tuner Pro, will increase MB voltages, so you don't get this.
If it does it again, and you are on stock, try to press the pwr button several times.
cool, thanks. I'll try this today.

Mine has never worked on any rom with any configuration. Turning off wifi helps sometimes.
