I seems like we have a discrepancy in how much battery life a TF uses in standby. Some folks seem to be burning <1%/hour, others >3%/hour. Obviously, this makes a huge difference in the total time a TF can be expected to last on a charge.

Please indicate how much yours burns per hour. Please ONLY answer if you run your TF as follows:

1. NOT in airplane mode

2. With wifi in the default (run in background) configuration
[Eee Pad Transformer Q&A, Help & Troubleshooting] IIJBII:
What setting is to run wifi in the background?

Also, would the number of apps (singned in) and thinks like exchange emails factor into this?
[Eee Pad Transformer Q&A, Help & Troubleshooting] wynand32:
Yep, a lot of things could impact this. But, the dichotomy seems so clear-cut (literally, <1%/hour for some people vs. >3%/hour for others) that I don't think those things by themselves can account for the difference.
[Eee Pad Transformer Q&A, Help & Troubleshooting] IIJBII:
I understand and agree. There should be some type of baseline. can you explain what Wifi setting you mentioned above? I have 3 options - Sleep when screen is off, Never when plugged in and Never - I know thats not exactly how they read but its something like that.
[Eee Pad Transformer Q&A, Help & Troubleshooting] wynand32:
The default is to "Never" disconnect...
[Eee Pad Transformer Q&A, Help & Troubleshooting] nxt:
Dunno how many %/hour, but I've gotten from 14 hours to 17 hours.

Picked up the transformer once in a while, put it down, etc..

Here's a screenshot of the 14hr one, charged it at the end for a few minutes.
[Eee Pad Transformer Q&A, Help & Troubleshooting] FrayAdjacent:
So you don't think the amount of data being communicated per application affects battery use in idle?

What do you think about signal strength from the WAP? (being further from the WiFi router, in another room, many walls and objects between the unit and the WAP)
[Eee Pad Transformer Q&A, Help & Troubleshooting] wynand32:
I'm comparing my results to what I'm seeing on the Xoom, which is pretty much identically configured to my TF (same email accounts, same apps installed and running, used with the same routers, etc.). The Xoom uses well under 1%/hour on standby, the TF right around 3.5%/hour.
[Eee Pad Transformer Q&A, Help & Troubleshooting] foxmeister:
I'very configured my TF to turn WiFi off when sleeping.

Yesterday my TF was unplugged and unused for a full 24 hours for an 8% battery drain.

[Eee Pad Transformer Q&A, Help & Troubleshooting] stuntdouble:
The reason there will be discrepencies between peoples devices is because everyone installs different apps. It's these apps that drain the battery more/less, so install a battery monitoring app and check the logs every few days. If you're losing more than 1% on standby per hour, then get a task killer program and tasker, and set up schedules to turn off apps at times you dont need them. Also make sure you have actually set the battery app up properly, by changing the rating it thinks the battery is (to 6600mA) instead of any default value it has.
[Eee Pad Transformer Q&A, Help & Troubleshooting] dazz87:
How would one change the battery to 6600ma instead of the default
[Eee Pad Transformer Q&A, Help & Troubleshooting] stuntdouble:
If you are using Battery Monitor Widget then it's from settings>monitoring preferences>battery capacity. Default was 1200mA on mine originally. If you're using some other app, I've no idea.
[Eee Pad Transformer Q&A, Help & Troubleshooting] wynand32:
As an update, I decided to go ahead and do a factory restore, just for kicks. I'm not experiencing much closer standby performance to my Xoom, about 1%/hour or maybe a bit less. In four hours since the restore, I've lost 5% battery life, and that includes a bit of use.

It's possible that the battery just hasn't calibrated since the restore, and so I'll report back if things return to what they were before. At this point, though, I'm hopeful that something was corrupted or misconfigured, and that a factory restore did indeed resolve the issue.
[Eee Pad Transformer Q&A, Help & Troubleshooting] dazz87:
Coolthanks for the info will have to check out that app. Right now i am using battery indicator pro whicb does not have a option to change battery capacity
[Eee Pad Transformer Q&A, Help & Troubleshooting] wynand32:
Another update after the factory reset: charged the TF to 100% and unplugged at midnight. At 8:00am this morning it was at 78%, so roughly 2.75%/hour discharge rate. At 10:00am (also only on standby) it was at 74%, so 2.6%/hour total for the 10 hours.

The Xoom was at 48% at 8:00am (forgot to note its battery life at midnight), and at 10:00am (also on standby) was at 47%. So, the Xoom on standby is burning .5%/hour, which has been my general experience with it.

Both the Xoom and the TF are configured with the same email accounts and settings, the same general configuration (wifi, etc.), and the same apps except for the Asus apps. Since my experience on standby was roughly the same with the original (non-updated) TF build, I don't think it's the Asus apps that are causing the burn.

If most others were experiencing the same thing, I'd write this off as a purely academic exercise. 2.5%/hour burn rate on standby isn't terrible, particularly since I tend to charge every night anyways. My concern, though, is that if others are getting <1%/hour with the same basic settings, and as I'm getting on the Xoom for sure, then the question becomes: is there something wrong with my TF specifically?
[Eee Pad Transformer Q&A, Help & Troubleshooting] Canadoc:
Well my transformer is doing better than that. I lost only 3 over 5 hours. Overnight from 10 to 10 battery went from 33 to 27 percent so looking at 0.6 % per hour. Btw I have wifi set to turn off with screen off. Why do I need wifi going if I can't see the screen. For mail when would wake the device it checks the accounts immediately. So........
[Eee Pad Transformer Q&A, Help & Troubleshooting] nsstrunks:
I've had my TF with me most of the day letting friends play around with it so it's had what I would consider "normal" use.

Starting at 100% this morning when I left and now has 65% after ~8 hours. (See attached screenshot)
[Eee Pad Transformer Q&A, Help & Troubleshooting] Kaoe:
I am battery anal too but anyone else feel like discussing a 2% drain difference in idle is kind of ridiculous.. no one runs exactly the same stuff on their devices of course it will be different... to be honest if you are concered about battery drain during idle.. you obviously leave your device unused alot... in which case battery life doesn't matter a great deal cuz you aren't using it hahhha
[Eee Pad Transformer Q&A, Help & Troubleshooting] Canadoc:
How did you get battery stats. To work?
[Eee Pad Transformer Q&A, Help & Troubleshooting] Canadoc:
Disagree with you. I think standby life is very important because the tablet is something you wanna pickup and have immediate access to for information a nd media without always Worrying if the battery's has enough juice. My nook color can go several days on stby and 3 to 4 days of casual use with standby. This tab doing same stuff is giving me 36 hours tops.

Cm7 on nook color has sleep issues and so doesn't enter deep sleep and so battery drain is about 2% instead of. 2% per hour on stock nook.

maybe our devices aren't sleeping deeply and draining much faster.

Something a Dev. can check?
[Eee Pad Transformer Q&A, Help & Troubleshooting] wynand32:
As I've mentioned in this thread, my Xoom uses less than .5%/hour on standby. My TF averages closer to 3%/hour. That means that over a 10 hour span, the Xoom will use 5% battery and the TF 30%. That 25% difference can be important if you're away from a charger and really need to get some work done, and indeed the ability to just pick up the tablet and use it without worrying about the battery is one of the advantages of the form factor.

That aside, what I'm most worried about is if there's something wrong with mine given that my battery use on standby seems like it's about three times as much as others running the same kinds of things. I don't mind the battery use as much as I do the notion that some component might not be performing to spec.
[Eee Pad Transformer Q&A, Help & Troubleshooting] seshmaru:
I think I may have a record here, 1 day and 10 hours unplugged and at 87% battery. This is with bluetooth tether and wifi on but not connected the whole time.
[Eee Pad Transformer Q&A, Help & Troubleshooting] wynand32:
Really, I do wonder why some people are getting so much better battery life with the TF than we're getting. At least one person in this thread or another I've been following is saying they get <1%/hour with wifi kept on and email syncing in the background. There has to be something causing some machines to burn so much more on standby than others (and, the TF so much more than the Xoom, when running the same things and having essentially the same components).
[Eee Pad Transformer Q&A, Help & Troubleshooting] wynand32:
That's the kind of standby performance I'm getting with the Xoom, and definitely NOT with the TF.
[Eee Pad Transformer Q&A, Help & Troubleshooting] seshmaru:
yeah I got 1.5 days with 13% drain with wifi/bt on, email push on, no apps in the background running at all though.

Also this drain isn't abnormal for me, I really think it's certain apps causing it. have you guys tried uninstalling every third party app and seeing what drain is like then?
[Eee Pad Transformer Q&A, Help & Troubleshooting] wynand32:
Another example. And I have the same basic config, wifi on (but BT off), email syncing, and no full apps running (just the services that load automatically). In 1.5 days, mine would die.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Canadoc:
Great numbers. Can you tell which Widgets you have loaded and also your network settings. Also are you using push mail? I think if we know things like airplane mode and GPS wifi and email settings that we can maybe find what resources seem to drain the battery most on standby.

No reason my nook color can drain on standby much slower than my larger battery transformer when screen is off.
[Eee Pad Transformer Q&A, Help & Troubleshooting] seshmaru:
I have both the gmail and email widget, weather with update every hour, pulse with updates every hour, push mail is on for both email apps btw. BT is tethered and connected, wifi is on but disconnected, no live wallpaper.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Canadoc:
Do you have work set to turn off with screen off?
[Eee Pad Transformer Q&A, Help & Troubleshooting] wynand32:
That was the purpose of the poll, basically asking for burn rate with airplane mode off, wifi set to stay on, and email syncing. If people responded correctly (which I'm not sure everyone did, of course), then it would seem that ours that burn 3%/hour or more are outliers.

It's also why it's a bit frustrating that the battery usage stats aren't working. At least then we could see what the culprit is. I'm really hoping that's fixed in a firmware update soon (if the inconsistency itself isn't fixed).
[Eee Pad Transformer Q&A, Help & Troubleshooting] seshmaru:
wifi stays on with screen off. so does BT.

EDIT: ROM I'm running is PRIME! v1.1 with my own modifications, but nothing that should reduce battery drain.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Canadoc:
Well I have BT off work on but set to turn off with screen off. Email has push exchange and have stock weather widget to update every 2hours.

Getting 0.6% drain per hour. I suspect wifi might be to blame. Since those with it off are getting good standby. Perhaps it is constantly on rather in low power state. I suspect this will be easy fix in next firmware.

As a aside I am the only one who feels the edges of all the ports and dock slots are razor sharp?
[Eee Pad Transformer Q&A, Help & Troubleshooting] Canadoc:
Is wifi set to stay on with screen off?
[Eee Pad Transformer Q&A, Help & Troubleshooting] Canadoc:
Do you know if that Tom is using a different wifi driver. Can you check the work and GPS version numbers in settings about tablet?
[Eee Pad Transformer Q&A, Help & Troubleshooting] seshmaru:
it's using the same drivers and same kernel as stock 423.
[Eee Pad Transformer Q&A, Help & Troubleshooting] wynand32:
As an update, I did another test. This morning, I set wifi to turn off when the screen turns off, and between 12:30am and 8:30am my battery went from 95% to 92%. That's equivalent to how the Xoom does with wifi set to stay on.

So, clearly, wifi is stopping the system from entering a standby state of some kind (and maybe it's wifi that's not doing it), and so is something Asus should be able to fix in a firmware update. I notice they've updated the wifi driver twice now, and so they must be aware of issues.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Canadoc:
Hey didn't I kind of say that?

Lol
[Eee Pad Transformer Q&A, Help & Troubleshooting] wynand32:
Yeah, now that I get caught up on the thread, you kind of did. :D
[Eee Pad Transformer Q&A, Help & Troubleshooting] Canadoc:
Anyway it is reassuring that this is fixable. In meantime I have no qualms setting wifi to turn off when in stdby as when I wake it up it should in theory just sync whatever hasn't been while asleep.

My bigger disappointments are build quality and I am on fence about returning and waiting for the Samsung. I find the copper edges are quite sharp at the ports and if pressed at certain edges it clicks creaks. Not sure why they couldn't have made the edges smooth.

An of course the light bleed is a problem too though only really at night when reading or watching a letterbox video.

Hopefully some more stock comes in before my 14 day return comes up. I so maybe a new batch will be better quality and I will not feel a bit uneasy about keeping it.

I also find even with thumb keyboard that it is a bit hard to type and the Samsung dimensions should be smaller fir same size screen. Also the 8.9 inch model is intriguing as I love my nook color for reading and games but find it a but small for surfing and movies and the reverse for the TF. so a slightly bigger device might be best of both world.

wifi

I always wondering why wifi burns almost the most battery life at runtime 37%!! The backlight burns 45%!
[Eee Pad Transformer Q&A, Help & Troubleshooting] rxnelson:
Any more insight on this?

I was convinced it was the antenna as well until today. Like some of you I want wifi always on. So I charged to 100% opened only a few apps and used auto airplane mode with wifi set to stay on. I basically only unlocked the tablet today to monitor the battery and ensure the email was synching. While it is no ipad2 it was the best standby life I have gotten on the tablet alone. So far I've used 8% in 12 hours. I would think this could be improved as my wife's ipad2 seems to stay at 99% for a few days in standby. However, my previous 3-5% loss per hour makes me think it is either the number of applications sending notifications or perhaps a rogue app. I don't want to factory reset so I guess I'll keep plugging away and monitor app by app.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Grnlantern79:
It's just has to do with constantly searching for signal. I gave my daughter my old Droid and I always had airplane mode off even through she didn't have service it was just a game phone to her and it would last a day with her playing games on it once i put it in airplane mode and it no longer searched for signal it last 3 days now. I know this is not what you were looking for but this is all the info I can help you with. If you wanted to root your tablet you could install ROMs and kernels that will allow you to adjust power used and squeeze more juice out of it.
[Eee Pad Transformer Q&A, Help & Troubleshooting] rxnelson:
I would tend to agree with you but there is a definite difference between <1%/hr to 3%/hr loss. The only thing I can think of is leaving some of these apps open is causing >3 times more drain. I'm not ready to root yet. I haven't done enough research on it. How do you do it, how to get it back, how to fix it if it bricks etc....i like to be ready instead of getting back in here yelling help if something doesnt go right.

root + setcpu + screen off profile@216mhz= WIN!

Been using this since day one with the TF & OG Evo. I leave the wifi on24/7.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Grnlantern79:
Leaving apps open don't cause a drain since Linux which is android has its own task manager standard and keeps apps in check which is why you should never use a task killer since android will open it back up and that is where you lose power on the app opening over and over. Root process is pretty simple you never listed what device you have that will help us point you in right direction.

When I turned off GPS, my batterylife improved drastically. Now, I get more than 5 days standby and more than 19 hrs operating! .. Who needs GPS anyway ;)

//edit; with dock battery included, that is
[Eee Pad Transformer Q&A, Help & Troubleshooting] rxnelson:
Sorry I assumed everyone was talking about the transformer. That is what I have. I know it isn't supposed to use extra battery but that was the only difference I could note between awful standby and acceptable standby. It could be the device I guess. It may be this thread or some others but I've seen other users state they have a xoom or galaxy and the standby life is much better than their transformer. I don't use the task killers.

Mikebz5, what kind of standby you getting with your root? Which rom?
[EVO 4G Q&A, Help & Troubleshooting] Lolfox:
I got a little problem here :confused:

I was playing Angry Birds today when everything just froze.. touching would do nothing.. side buttons/power button wouldn't do anything.. not even haptic feedback on the touch buttons or whatever.. This had happened to me before, and the phone would restart itself, blabla, everything would be cool again.

Not this time!!

I turn my phone on but the boot (HTC) screen will stay on for a few minutes.. then goes black, and then vibrates and starts again.

At first I thought this was a problem with my ROM (CM7 Stable), so I tried going to the bootloader menu. It came up, but was unresponsive. I try and try again but only some times will it actually be functional, and even then, when I try to go into recovery, the boot screen stays stuck.

How ****ed am I?
[EVO 4G Q&A, Help & Troubleshooting] rugedraw:
Not much at all. If you can get to the white screen and to the boot loader, it can be fixed. Do you still have your recovery installed? Try holding the volume button down while booting and see if it goes into recovery. If so, you can restore the NAND back up you are supposed to have done. If it goes into a black screen with a red triangle, your recovery is gone and you have to reflash it via the boot loader by getting a flashable zip file on your SD card and naming it "PC36IMG.zip". (Make sure you do not add ".zip" to the end of the file name, or it will be named "PC36IMG.zip.zip" and will not be recognized by the boot loader.)

Amon RA recovery zip file can be downloaded here ready to go: http://files.androidspin.com/downloads.php?dir=amon_ra/RECOVERY/&file=PC36IMG.zip

If you do not have a NAND back up, just try wiping the cache and dalvik cache and try booting again. If that doesn't work, you may need to reflash your rom as if it was a new install and start over.

Worse case scenario, run the latest RUU and start over from stock.

Edit: If you did create a NAND that you want to restore, and you created it with Clockwork recovery, you will need to flash that recovery and not the one I linked to you in order to restore it.
[EVO 4G Q&A, Help & Troubleshooting] dougjamal:
