My wife and i both have MT4G phones. While mine works perfectly fine, My wife's is having issues that I can figure out.
First, let's say that she 76% left on her battery, the phone will just power off. But when the phone is restarted, the battery will be at something like 8-20%. Now I thought her battery was bad so I swapped her battery for my battery to see if i needed to buy a new battery.
With her battery in my phone there were no issues with my phone and conversely, her phone with my battery and it does the same thing.
Anyone else have this issue?
she probably has a rougue app. One that's juicing the living **** out of that battery. Look through her apps and see if any of them run while device screen is off. Its probably an app thats syncing constantly.
You can check these by going to settings/about phone/ battery/battery use. There's you'll see the apps that are running and which take alot of juice out of the battery.
You can also reduce sync for anything by going to settings/account and sync. Thee you can change sync intervals or stop anything from syncing at all.

This is common with mine, it does it while charging. Its not a rouge app. Cause ive tried it and cannot find any app that is running it unless its shadowed. I dunno but it happen a few times already. I use cm7. Now it can also be related to emmc chip. Kinda curious only a few people have these issuses. Wouldnt it be more wide spread and more people have problems with it, if its an app?

I would say to try and do a factory reset.

That would happen to me if I wiped battery stats in recovery.
And on some Rome.usually full wipe and reflash solved it.
Haven't wiped battery stats in a long time,and I haven't had that issue since.

Hi, I picked up a new 7" Tab 2 a few weeks ago, and it seems to randomly do an automatic shutdown if i haven't used it for a while. Sometimes when picking it up after putting it down overnight, or after I've left it home, the tablet is off, not just asleep. It also doesn't seem to matter if it is plugged in to power or not. Is this normal behavior, or is there a problem?
I would say it's a problem. I've left mine for several days on and off the charger and it never shuts down. Are you stock?

Completely stock.
It could be a problem but, I've seen some tablets that have a setting to switch off after a certain amount of time. Check all your setting see if there's anything either ticked or highlighted by radio button to switch tab off
I have same problem one week ago, tablets restarts in my pocket two or more times in a day, since I installed cyanogen mod firmware al is ok, I was thinkin that may be an app is that make restart, not a hardware problem

Its software on your tab. Trust me lol. Wiping or getting another rom will probably fix it.
So... I cannot turn on my Asus tf101 unless I plug it in to a power source, once the screen lights up I can unplug it immediately and it functions normally when turned on. I bought this device refurbished from best buy a few months back, I dealt with the issue but now am looking to sell it. Any ideas on how to fix this? I have never rooted the device, however I have tried factory resets and cold boots.

Are you holding the pwr button long enough. If so,it sounds like the switch is bad.
I hold the power button for 12 seconds and try it with different variation holding volume keys. It functions fine when the device is powered on.

It could be a bad battery or your charger is only giving enough to power the device on. I would try a new charger first.

But once powered on, it functions flawlessly. The only issue is turning it on.

Do you have the keyboard docking station for it?
Are you on custom ROM or OEM?
What "app killers" are you running?
Some custom ROM's have had similar issues a long while back. maybe yours is getting that issue IF your running custom.
Keyboard dock, if you have it, does it do the same thing for powering on, where it needs to be plugged in to start the screen?
I only ask about the app killers because I had experienced a similar issue about a year ago due to an app killer I had installed. Removed it, and the phone worked fine. Put it back on and it reverted back to having to be plugged in to start the screen.
Have you tried a clean wipe of everything on the tablet? And I do mean CLEAN, no dirty flashes here (keep your pants on bud).
Lastly have you given the charge port a good ole blow out lately? Long bursts aren't really going to do any damage, but I would stick to short quick bursts of compressed gas, again NO VACUUM CLEANERS. They create static and the charge port is quite susceptible to static discharge.
I know your pretty intelligent, but let me put it out there again. DON'T be a fool and use alcohol on your tool.
This post made me laugh. I do not have the keyboard docking station. I have never installed any task killers as I do not believe in them. The tablet has been running the stock ROM the whole time and has never been tampered with.

But you never said if you gave the ole girl a good ole cleaning in the slot.
I would venture to say that you need to send it in to Asus or take it back to Best Buy (if your able to). It sounds like there may be a voltage issue with the digitizer or the inverter.
And NEVER EVER EVER Invert your digits while cleaning out the slot.
You also didn't say if you went deep up in the ole girl and gave her a good rootin.
I'm working with Asus right now and of course there's something wrong with my serial number. Nerve been rooted. Blew it out and that did nothing.

Please keep us posted as I am curious to know how ASUS customer service is to deal with.
Well, I am trying to send my TF to Asus to fix the problem and they are a bit annoying. I have just dealt with HTC before and that was wonderful, but here they have send me 4 emails asking me to wipe, to update and to do everything that I have already done, and after that they have sent me to another web to fill another questionary. With HTC I just had to told them the IMEI and in 4 days I had my phone back
I had similar issue with mine. It was one of the reason I took back to best buy and used the buy back.
I then picked up the Nexus 7.

I had a similar issue, do you use your device often ?
I figured out after a couple of months that each time it showed this behaviour the battery was in fact empty and it was in fact the root of the problem.
My transformer take much longer time to boot when plugged even with a full battery, and when it's empty it doesn't boot at all.
I must plug it, wait for it to be enough charged to boot unplugged, and do so. Then plug it back when started.
Considering that the transformer on stock cannot shut off when plugged to its keyboard (or even to USB ? Or is it just mine ? When I shut it off plugged to the keyboard then close it, it boot on again) When the tablet is left for several days unused the battery will be empty.

Yes I do. But even if the device is fully charged it will still not power on unless plugged in and I don't have the dock.

Do the power and volume buttons work normally once fully booted? I have had similar issues, one was improperly seated power button, the other was a loose ribbon cable way down in the guts of this beast. Also, was this happening the whole time you've had it , or after a firmware update?
Right now I'm dealing with one that the screen won't stay on once I get into ics unless I'm plugged in. I went in and noticed that if the auto brightness wasn't set, it works. So I tweaked the settings in display time off when unplugged and uninstalled some screensaver app, and now it's working fine. It was probably the first thing, even though was already set to one minute. Anyway, just letting people know sometimes it isn't hardware. But the op probably is since he's done factory reset.

Mine was and at first I blamed the case. But it does it with every case. So i was thinking of returning it. But then I got this email from Poetic(i had slammed them on Amazon with a one star rating). It said:
We would also like to inform you that if you face any issue regarding wake up function mostly when you open the case we request you to please check your WIFI Connection (to make sure you are successfully connected to WIFI). If your WIFI connection is disabled or not connected to WIFI Successfully, then your device won’t wake up all the times. This is not the issue of the case itself.

I tried turning my WIFI on and connecting, but it did not help. Then I tried with it off. Same problem. Now I am thinking I really need to return this thing, only to find out my friends does the same exact thing. So what the hell? Are they all doing this? Most? Only a few? I really do not want to return if all of them are gonna do it, and it would seem a software issue in that case. But if mines got hardware problems I really should return it.
My case has been working fine.

Hate to say it but if you are on stock, I think the device crashes and does not power on with the cover anymore. I had that issue when I was on stock.
I've since moved to CM10.2 nightlies and the cover turns on the device every single time. No issues here.
Also, with CM10.2, no more random reboots. You owe it to yourself to get off of stock.
There definitely is an issue with having wifi on and no access point around w/r/t magnetic on
I've seen this on a couple of units
Here are the symptoms with my cover:
* It never fails to put my tab to sleep.
* With wifi off, it rarely wakes up my tab. With wifi on, it wakes up the tab quite often... unless the Tab went to a deep sleep.
* When plugged in (PC or charger), it works beautifully, wifi on or off.
So it's hard to point the finger to Poetic.
There are plenty of people who don't have any issue.
I have replacement coming from the Amazon seller, so will see.
Open your case and WAIT...
so far mine always turns on... BUT it may be delayed by 10-15 seconds.
(by that time most of us have closed/re-opened the case a few times).
Mine works like a charm, I cycle through every Locket ad in like 30 seconds using my cover lol
Mine fails perhaps 20% of the time. It can't be a cover issue though, because the cover is constant.
Just tested my Moko ultra slim case on CM kanged and it turns on and off like a champ. Quick and no delay. No reboots either. So for me it was a software issue.
For you, flash CM and see if it is. If you still have the problem on CM then exchange it.

Mine works fine with CM10.2 as long as WiFi is always on. If WiFi is set to turn off when sleeping it will not turn on after 15-20 minutes.

I posted about this same issue here: http://forum.xda-developers.com/showthread.php?p=44926734
Sometimes it will wake up after a delay (20-30 seconds) and sometimes it will just sit there until I press the power button. My first gen N7 never had this problem. I really don't want to let my WiFi run 24/7 just so my tablet will wake up.

WiFi seems to use very little power. I average about 10 hours of screen on time per charge.

I'm using the MoKo case and do not have any problems with the case not waking the device when opened. I must say though I did not purchase the case for this feature. The case construction is good, it fits the device perfectly and looks.well in place, and provides protection for the screen. For those reasons I am satisfied with it.
Just got a poetic replacement case, no improvement.
But (at this point) I think it's a tablet issue. If google knows they will fix it later, just like some people having multi-touch issue.
Even with my WiFi off, on CM, its perfect. Tested with WiFi off, even waited like 5 minutes and tested again with no issues. Probably a rom issue. Is this on stock with the latest version?

Mine is stock rooted, latest version, with a Moko case. If it sits idle for more than a few minutes, it will rarely turn on when the cover is opened. With short idle times, it will wake consistently. I may try CM eventually but, for now, I think I may just flash the Bulletproof kernel and enable the double tap to wake feature.

My wife recently dropped her Razr M in the toilet (gross, I know). The phone never turned off (I'm not sure how to do that), but I put it in some rice to try to get the water out. The phone now boots up and seems to work but the battery status is unknown and therefore it won't charge properly. Would a battery replacement fix the problem? If that's the case, where should I buy a battery? Is it even worth it or should I go buy a new phone?
I had a friend bring me an htc incredible with this issue...his baby slobbered all over it... the battery icon had a ? In it and in the about phone area battery status was unknown... A new battery did resolve the issue but over time corrosion set in and the device begin to lose functionality... captivate keys stop working proximity sensor stayed on notification led stayed on... Then the screen stopped responding to touch... with our device having a non removable battery didn't help matters..
