I noticed that the phone turns the moment the charger is connected to it (or if the USB cable is attached from a PC that is on). There doesn't seem to be a way to charge the phone with it switched off.
Do the others notice the same behaviour or is this a problem with my Omnia? Is there a way to disable this?
Yeah I have the same thing you cannot charge it while it is turned off. This is true from all the iPhones I have used aswell. It isn't a fault don't worry about it.
I don't know if it can be disabled but why would you want to out of interest?
I tend to charge the phone at night and don't want to receive calls.....

Flightmode is your friend
Settings -> Flightmode on
That cuts all wireless connections, you won't receive calls or SMS at night.
Noticed this too, my phone also reboots when I connect it to a charger too - anyone else had that happen?
With some reading i;ve been doing, *only recently started reading up about li-ion bats* seems they might be on to gain optimal charge / long life at the right voltage.
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
might be why...
I'm doing more research into it. But another reason i can think of is, When it's on. Boot up time isn't there. Flight mode is. I use it rather than turning a phone off now, saves turning on the other end, i can play a game, watch a video, listen to music on the plane and charge it on a socket ready for the other end.
Yes, i noticed this issue also... as i remember, in a small book that came with my phone there is written you can charge you phone when its switched off - it will charge faster.. but theres not written how never mind, its like that, and thats the way it is...
Oh this would be bad. I charge my phone at nights too, and have it next to my bed. If the screen would be on it would be too bright to sleep with (I'm a very light sleeper). Hmm...

No, the screen won't be on
The screen turns off after a minute or you can press the standby button manually.
It's just that you can't switch off the phone completely when it is connected to a charger.

Maybe it's some kind of power management that the OS is doing therefore it needs to be on.
Battery life is great on WP7 after all.
It's confirmed by pocketnow.com
the WP7 OS doesn't allow you to charge while the phone is off
Hey guys,
My Transformer took it's second "sleep of death" early Saturday and it is still in its "coma" state.
It won't turn on or respond to any buttons. Should I contact ASUS about this problem? Any tips on bringing it back to life?
Thanks
Don't have one, but everybody does the same: keep power pressed for several seconds, so the tablet will power off, then power it on again.
Check this forum and the development one, and you will see several threads for the SOD problem. You can turn it on again, but it seems that, right now, there is no failproof method for keeping the tablet to lock while in standby. Well, it seems it doesn't happen if you have the tablet plugged to the charger while in stand by.
Anyway, as I told you, check other posts to see what the people are trying / suffering.
Regards.
If you have it in the keyboard dock I would remove it. Then press the power button in for several seconds.
Did it do that overnight whilst docked? Mine did that There is a known issue with the dock discharging overnight when connected to the tablet. I think Asus are working on a firmware fix for that.

No I don't have the keyboard.
It has happened twice to me and it's always after charging the device (so far).
I woke it up earlier tonight. It charged fully on Saturday, and was completely dead today. This is probably not too good of an issue...
Only true lives kiss can wake the sleeping transformer from it's unnatural slumber.

I'm having trouble charging my device.
For some reason, after updating to the new 3.2.1 my tablet win not charge either from the adapter, usb pc connection.
Tried rebooting to no avail.

I don't think this has anything to do with the update. Mine updated and charges ok.
I did however have a problem charging once (before the update) and I searched the web for solutions. I think you will find it's a problem with the mains charger. It overheats and the thermal cut-out fails to reset. As mad as it sounds the solution is to pop the charger in a plastic bag and pop it in the freezer for 30 minutes. It worked for me and countless others and is worth a try.
Good luck though.
had same issue. seems my charger was not well seated with the clip on plug.
Non issue

Wow! I tried to google search on unable to charge after updates, but could not find any meaningful matches.
I will try this fridge trick, although it's another example that asus really rushed this entire project out! We have been beta testing an unfinished product.... But I guess that's the norm these days.
Thanks!
I find that sine the latest update, the battery drains faster and I have to plug it in and out a couple of times until I see that it's charging..Also, all of a suddent the touchpad (not the keys) will wake up the tablet when it's docked

The touch pad will not wake up the tablet if you turn wifi of MANUALY before putting the tablet in sleep mode !
It's how I fixed it, waiting for Asus to fix it

If it bothers you then you can always disable the touchpad... I'm still on 3.2 but the touchpad always intefered with my typing so I have it disabled by default.

Same problem for me :-( I found that a reboot will solve this until it happens again. Need ASUS to fix.

Hopefully yes, a reboot fix the situation. Today, i'm trying to not disabled the wifi (or, turn wifi off manually each time), and i'll see if the USB/SD disconnet again !

It's not really a bother, but it shouldn't happen. Turns out the tablet, with the new 3.2.1 update is not able to sleep. I think it's something to do with the new wifi "improvement". Using cpuspy, the tablet is not sleeping at all unless I manually turn off wifi and reboot. This needs to be looked into and corrected by Asus, unless I'm incorrect or have an isolated incident.
no, it's note an isolated incident, i have approximatly the same situation here !

Not the case for me. I had all sorts of sleep/reboot issues with 3.2 (using custom roms and kernels), and nothing resolved them other than a complete return back to stock with a full bios wipe.
Since updating to 3.2.1 and then to Prime 2.01 (sticking with stock kernel), my tablet is turning wifi off when the screen goes off, and is going into deep sleep as evidenced by the fact that it is only using around 2% over 9 hours while not being used. I was concerned that like others I would have sleep/reboot issues when docked as this seems to be a problem, but tested that issue last night and when I checked today after not using it for 10 hours, no reboots, no ramdump.log and battery life used was minimal in line with deep sleep.
I truly believe that the solution to all these issues is to completely return to stock - including the part where after you have removed CWM (if you have it), you start the tablet holding down power and up to enter the asus startup mode and then select the option that wipes everything. But YMMV....
As for my original issue when I started this thread, it turned out the charging issue was indeed a problem with the charger overheating as pointed out by another member (THANKS), as a quick 30 minutes in the freezer seemed to reset the internal thermostat. From now on I unplug when not using the charger.
^^^ That's cool that yours is under control, but mine is stock, unrooted. Don't really have the inclination or motivation to root this thing..But it appears that it is a definite issue for stock, unrooted Transformers, judging by response
Same here, stock, unroot ! But I prefer waiting for Asus inseed of turning back to custom ROM...

Solution to this is unplug your transformer, keep it as tablet only, press and hold the power button for over 30 seconds, plug in and then switch on.
Worked for me Asus says the issue is a static build up on the device with having external devices plugged in, like hard drives, not sure if thats accurate, but the fix has been solid for me!
My Tablet and Dock have the same issue since the last OTA, charge doesn't works. PLIZ ASUS FIX THIS ISSUE !
8-10 in the freezer and my tablet off for those 10 mins worked for me.
I was using my Nexus 7 til it hit about 15% and the battery alert came out. I turned it off, plugged into the charger and left it there overnight. The following night I took it out of my pouch only to realise that its very warm. I had to press on the power button for a good 10 seconds before it turned on, and when it booted up the battery had only 5% remaining, even though it was fully charged (I checked to make sure it was 100%) and was left OFF the entire day.
I encountered this before but thought I solved the issue after wiping the device and flashing CleanROM 3.0 without any custom kernels or tweaks. Looks like the issue is back, any idea what might be wrong? I hope it has nothing to do with the physical battery itself because that would be a pain. Other than this, the day to day battery life of the tablet and stability is pretty good.
BUMP
No one really? Im sure there are people who experienced this before.
My wife's phone does something very similar. Crashes, heats up and when she gets it back on the battery has taken an absolute hammering. Luckily it occurs only rarely and it appears that there are no long term consequences.

What phone is she using? Is it rooted?
Anyway I think i figured out why, i happened to notice it by chance. After full charge, i plug it out and notice the screen is actually turned on even though the device isnt! The screen is just showing a plain blank screen, but you can tell its turned on, by looking at an angle. I had to manually force a shut down by holding the power button before it goes off, then the tablet automatically switches on. It seems that it only happens when i charge the tablet while its switched off, I wonder if it has anything to do with the bootloader (Im on 4.2.1) or the charger itself.
Galaxy s2 rooted, does not appear to be rom or kernel specific as it occurs with different combinations. Anyway good news you have at least identified the problem.
Cheers Danny
Sounds like it never charged. Why turn it off to charge it? Airplane mode is just as good.

It did charge because when i turned it back on it showed as 95%, the first 5% was drained because the screen was left "on" the whole time. I am beginning to suspect it is the case I use with the tablet. Its similar to those smart cases on the iPad where the screen auto ons/off when you flip or close the cover. I notice that even during the process of shutting the tablet down the flap still affects the screen off/on when i close it. A potential way of screwing up stuff. Next time I charge it turned off, I'll try removing the case entirely and see what happens.
Alright this time I turned the tablet off and left it to charge over night WITHOUT the casing and now it's working fine. No screen on or any heat whatsoever.

Why are you turning it off to charge? Just plug it in and be done with it. I never turn any of my devices off - the only time my S2 has been off is to reboot to flash a new ROM. Never have any charging issues.

Its just a habit i guess, and i always have the mentality that it makes a difference charging it while off
And its also good to reboot your phone once in a while, I usually do it once every 24 hours of use. Y'know, to flush out the RAM and OS so it can start anew. :highfive:
My phone is shutting down automatically after showing “google” logo. I went back to stock lollipop 5.0.1 but the problem still persist. It’s working fine with the charger plugged in. If I remove the charger after switching on, if I kept it idle, it will stay on till the battery is empty. But if I try to do something it will shutdown. In recovery mode it works well without the charger.
Please help me is anyone facing the same issue.
may be you should try flashing a new kernel
i tried stock Google images still no use.
Is there any noticeable bulge to the battery? It might be a battery issue.
This is almost certainly a battery issue.

I don't think its a battery issue, because if i keep my device idle it'll last 1 day.
It only crashes if i use the phone, even swiping home screens crashes the phone.
Well, you've already gone back to pure stock which rules out a software issue, and so the next thing I thought would be a battery issue. I have read here about defective batteries causing all sorts of problems like losing signal, non responsive touchscreens and bootloops, and so it's a possibility that this is a battery problem.
I got strange problem with my n4..
Battery % randomly change and shut down, unsensible touchscreen, battery icon disappear from menu..
Maybe this hw problem could touch the SW part
that's how my problem started

My nexus 4 cant't turn on without charger plugged in. But when I go to Recovery, it work fine. A few days ago, it's sometime shutdown suddently when I was playing game. Then it worked fine after I plugged charger in and turn it on. Is this battery issue?
So even when the device is fully charged it won't boot into Android?
