Backlight coming on for no reason whilst on charge - JASJAR, XDA Exec, MDA Pro General

I've got my backlight set to turn off after 5 minutes when on external power, 3 minutes when on battery. I have recently got a new battery but that's not relevant since this happened with the old one too.
When the device is charging via USB it frequently turns the backlight on by itself. I do have activesync running but I don't actually sync anything. It happens at least once every 20 minutes, so it gets annoying overnight.
Can anyone think why this is? I don't have the computer interacting with it, nor do I touch it at all...

It could be ActiveSync being the annoying little M$ thing it is... it will run itself automatically (why M$ feel this is appropriate is anyone's guess) thus making your device think that it's in use.
That's my 2 cents, seems logical. I always close the lid when on charge as the same happens and I'm worried it'll burn out the screen.

Really sorry for the double post... I pay for a 10mb connection and most of the time I'll be lucky to get 60k and their best solution is for me to downgrade!!!! This country sucks a$$!!!! Moving to BT

Random Switching off, Losing Time/Date Settings...

For about 3 days now my wizard (G3) started switching off randomly, losing time/date settings after being turned off for a longer period. I've been using it happily for a year now, with pretty much no issues whatsoever. The first time it happened, I guess it was too cold, cause I'm wearing it on my shoulder in its default leather case/bag. After powering on the sound was somewhat distorted - everything sounded as if played at a different frequency - faster and a tone or two higher. After a soft-reset the sound was back to normal, but then the other issues started - sometimes it'll lock on boot-screen, sometimes, it will power off again just after powering on and entering the PIN-code, or just silently turn off while hibernating.
Any ideas? Suggestions? Similar experiences?
I haven't updated the ROM since the first update to Molski's (WM5) about a year ago, shortly after buying it, and it's been fine so far, never had the time to deal with another update with the whole plenty of ROMs available. I don't thing it would have anything to do with that.
ALSO: Is there any logging utility or anything that could provide any clues as for the reason why it switches off? (edit)
Any help would be appreciated! Cheers!
Similar Issue
I have a Cingular 8125. It has been working great with the stock ROM for over a year now.
In the last few weeks, it has started to exhibit the same strange behavior that yours has. Sometimes when I wake up in the morning, it will be sitting at the password screen like it rebooted over night. I keep it on the charger all night though!? Also, in the middle of the day it will just shut off. When I try to reboot it, it shuts off again during startup. It usually keeps doing this over and over again. It seems that the only way I can make it reboot is to plug it into a charging cable.
The other day at about 11am, after charging all night, my phone gave me a little beep. When I looked at the screen it said that the battery was dangerously low and I should recharge. Before I had a chance to do anything, it shut off! I pulled the batter out and inspected it. It seemed a little bit bulged in the middle. I am not sure if it is dead but I am pretty sure there is something wrong with it.
Needless to say, a new battery is on the way!

Really annoying problem...

Hey guys.
I'm experiencing some problems with my Touch HD. When I get it to start I'm really happy with it and every program runs as it should.
My problem is the battery or something like that. I can have the battery power at 70% one second and the next the phone is telling me to either charge the battery or the device will shut down. I try to start it again but at the start screen it says Battery level to low, your device will shut down.
When I try to charge it the LED under the power button will show a solid amber light, telling me that it's charging, for about 7-9 seconds and after that it will either start flashing between amber and green light or just turn off.
I've tried having it like that over night and try to start the phone in the morning and the same message appear on screen, "Warning! Battery level to low! Your device will shut down!"
Read in some other post about someone who had a similar problem, but not quite the same, and that was resolved by removing the battery, plug in the USB cable for a few seconds, disconnect everything and then put the battery back in and start the phone. This works for me about 30% of the time. When it works the battery shows about 60-80% power.
I've tried a hard reset and I've tried to contact HTC without any success. Any suggestions from you guys, you seem to know almost everything there is to know about these phones.
Thanks.

Have you tried keeping the battery out for a day?
When I got my phone, the first 7 charges I turned the phone off and charged it all the the way up (to get the calibration accurate). Now the battery life is excellent, I can use it for couple of days without charging.
You should try returning the phone, seems it is fine software wise. Can you use the phone with the charger in? If yes, then there is probably something wrong with the battery or the hardware that is interacting with the charging.
I've tried keeping the battery out for about 24 hours but it didn't help. I can't start the phone when I have it plugged to the charger. I'm going to return it today and see if they can just exchange the phone in store or if they need to ship it somewhere to be repaired
Thanks anyway.
Sounds like a defective battery to me...
That's a good idea, better to get a new one.

switch off wifi, install Advanced Config, select all power management enabled
and try again. i also had the situation that my hd took 1550 mA. so the battery was sucked empty within several hours. now everything runs perfect...
Have exactly the same problem
I have exactly the same problem. One moment the phone works and charges fine and the next it shows irratic battery levels and eventually needs to be shut down. Following the shutdown you get the 'Battery level too low' message on startup, right after the Smart Mobility screen. In my case I think the problem mostly started when the phone was either just connected to a PC using the sync cable or when trying to top-up the charge using the wall charger. I also noticed that when the problem appears the plug symbol would appear (indicating it is charging) or sometimes not and then when checking the battery level, the indicators would actually go down sometimes losing 2 or 3 at a time until there is only 1 left and the phone says it needs to shut down. Pluging in the wall charger does not help as the LED indicating the phone is charging only stays on for a few seconds.
Now, I had many trials with removing battery, sim card, memory card or any of those in combination and sometimes these seem to work, but I think the key is the temperature of the phone. Every time I went to the car to drive home, where it was cold, the phone would start charging again, when just before that it would not react to anything all the time I was in the warm office.
I have now contacted HTC and am sending it to their repair centre tomorrow. Hopefully this is recognised as a fault and I will get a replacement. BTW, they arranged for a free courier pickup. Not bad, but the key for me is that the phone is being replaced as I really like the phone.
Update: Got a replacement after 1 week
Got my replacement phone today and hope that this time I have no further problems. I also had to return my previous one with a screen problem (see my post here http://forum.xda-developers.com/showthread.php?t=439410&page=2).
Everything went quite smootly and I liked the offer of a free of charge UPS pickup, so the only complaint I really have is that HTC send me a new phone but no replacement screen protector. Just the original screen sticker (the one with some writing on it) had been stuck on. It was in a bit of state like it had been taken off and put back on several times. I just called them to send me a replacement screen protector, but I don't hold my breath to get one. Probably end up buying it from the website.

[Problem]: usb to pc connection not working and excessive heating

The problem is that the phone is suddenly becoming extremly hot anytime it is charging or turned on. If I turn it off and let it cool down and then turn back on it becomes very hot in just few minutes. The battery after all night charging will discharge in 30 minutes max if i don't touch the phone, if I do anything or softreset it will discharge in immiedietly. If it has 95 % before softreset after it will be be like 5% and giving me alert about low battery level. Charging process is also much slower than normal, after 5 hours it will be around 50%. Before it was up to 100% form 5% in 4 hours max. This is all about power problems that made me think it could be battery dying... but propably not the case :/ Plus the battery doesn't heat up only the shiny black part around usb port is the place from where all the heat comes.
The other problem is that active sync or usb mass storage connection cannot be established. The computer doesn't see the phone at all. Moreover it will always charge the phone via usb even if I disable charging via usb in power options.
I tried a couple of hard resets and reinstalled newest official rom available on htc europe website from nbh file on a card (since usb is not working and I had spl 1.56 from that rom on the device already) This didn't help.
I am pretty sure now it is not a software fault or mechanical injury since I've never dropped the phone and always had it in this htc sock. No water contact was ever possible. It was just a regular day when this happend and I noticed it when the phone was in my pants pocket and started to burn my leg. Think it is some hardware issue related to usb port or anthenas since this is the source of heat.
Already returned my HD for fixing, but just thought I would let everybody know what happend to me. Anybody had a problem like that with their phone or maybe knows what is going on with this crazy Touch HD device?
My HD has started doing this in the last 10 days!
The black shiney part is get way hot, even when its not even on charge!
It wouldn't connect to active sync but would just as a disk drive.
The battery is running down to about 60% from 100 in less than 1.5 hours with no use!
I've never dropped the phone, spilt anything on it or anything.
I've hard reset it twice, and it was back to normal for a day, then started doing it again so i turned the phone off and charged it over night, was normal for about 5 hours after turning it back on, and now its started doing it again! I'm going to try the test on HTC's website to test if its a faulty battery but this doesn't explain why its getting so hot????
Let me know how yours turns out, i'm going to call orange insurance and see what they say!

[INFO] Troubleshooting Common Problems

*Please be aware that if you have rooted your device you may get undesirable results from daily use that I haven't covered here. That is a risk you take or something you have to put up with or solve/workaround yourself, or with your rom provider.*

Have a problem with your dock/battery?
Read THIS first.
My FOTA update keeps failing to install.
You have to fully return your device to stock (not just unroot). Use NVflash to do this. Then go to the asus ftp server and download any update file. Update your device using that file and this should allow your device to update FOTA properly.
Get a tingling sensation when plugging in a charger?
Flip the charger over and plug it into the wall so that the S in asus is on the side with the fat slot on the plug to fix. Seems to be a faulty adapter issue.
My screen isn't displaying anything:
Make sure none of the side buttons are stuck. Press them and make sure they 'click' ok. Force power off your device (10-12 second hold of power button, then release). Wait for about 30 secs. Then power it on normally (6sec power button hold and release). If your screen worked, then stopped, try discharging the battery to 0%. Then re-charging it. This has seemed to clear screen responsiveness for lots of people.
My dock battery is dead and it won't start to re-charge:
Try this tip HERE.
My speaker volume is stuck at a certain level:
Force power off your device (10-12 second hold of power button, then release). Then wait for about 30 secs. Then power it on normally (6sec power button hold and release).
My device/dock battery isn't charging OR my device/dock battery isn't holding a charge:
Make sure the charger is 100% clipped together properly. It's a very tight fit and may need slight force to snap together. Also make sure you have inserted the usb cable the right way up in your adapter. Sometimes unclipping, and re-attaching the adapter parts fixes problems (some come pre-assembled already so this may not be your issue). If your dock battery indicator doesn't ever go green after about 8hrs of charging (not for the first charge) then it may need RMA'ing. A normal charge of the tablet itself, from empty to full, should take about 3hrs maximum (not for the first charge).
My battery is draining very quickly:
Some apps run fine in the background, but there are others that may be 'keeping alive' certain functions, such as gps, sensors, etc. In order to get around this you can use free task killing apps from the market. It's recommended to be selective about which apps you choose to auto-kill. Don't just put them all on auto-kill (unless you are using a 'safe' option in the app) or your system may become unstable. If you have wifi on when you put the tablet in standby, it stays connected. If you then leave the network coverage area, the tablet will continually search for any network around it, draining the battery further. So when leaving home, remember to switch it off. Another possible cause of major battery drain is a badly coded/incompatible app. Get a battery monitoring app from the market and keep a close eye on the logs it produces. Don't watch every little blip/spike in the readings, try to take an average reading, over a few hours/days to get a better idea of what's happening.
Why isn't my device charging when I plug it into my pc?
It will only charge when the display of the device is off. And it is extremely slow and will only trickle charge. There are ways to boost power to your usb port, but the risks far outweigh any benefits.
My keyboard dock has X issue:
The next firmware update should solve many dock problems.
My touchscreen isn't working properly:
A future firmware update may resolve this issue.
My speaker balance is off (louder/quieter in one speaker than the other):
A future firmware update may resolve this issue. Or if you don't want to wait you can read THIS thread.
My X app force closes/crashes unexpectedly:
Check with the app developer/market for an updated version compatible with honeycomb.
The default camera app is showing a green screen:
This was fixed in firmware update1. Upgrade your firmware.
I don't have MyCloud or splashtop apps installed. Where are they?
These were added in firmware update1. Upgrade your firmware.
My email widget isn't updating and always shows 0 emails:
This was fixed in firmware update1. Upgrade your firmware. Then remove the widget from your home screen, reboot and then re-add the widget to your screen.
My wifi signal keeps dropping:
Update to the latest firmware. Set your router/modem to a specific channel (set it to 1-11, NOT channel 12 or 13). Failing that, it's probably time to buy a newer wireless N router/modem (the TF does not support 5ghz, only 2.4ghz).
One of my speakers stays on even when nothing is playing from it:
Put your device into standby mode for 5+ seconds. Then turn on again.
My charging cable is too short:
Some 3rd party USB 3.0 male to female extension cables work to extend the length. This seems to be the luck of the draw if it works for you or not.
I get horrible movie recording framerate issues:
This was fixed in firmware update1. Upgrade your firmware.
My microsd card isnt working:
Make sure it is formatted to fat32. Make sure it's securely fixed into the slot. It has to be pushed in quite a way. Use a long fingernail or the edge of a credit card. Make sure it clicks and holds in the slot. It should be flush to the side of the device.
I have dust under my screen or dead pixels or both:
Return and replace for a new unit by RMA'ing your device.
My MKV video playback is jerky/unwatchable/not working:
Make sure it's a low profile encoded file.
My device isn't powering on:
Perhaps you have put it into APX/nvflash mode by mistake (which doesn't display anything onscreen). Force power off your device (10-12 second hold of power button, then release). Then wait for about 30 secs. Then power it on normally (2sec power button hold and release). If still nothing you might have to RMA it for a replacement.
I can't install any apps from the market:
If you are in an unsupported country you can try THIS. If you're not and still can't install, sometimes google does maintenance that affects certain accounts. Try it again at a later time/date.
My onscreen keyboard is laggy:
Change the keyboard from the default Asus keyboard for the stock honeycomb one. Turn off text prediction. If still laggy you have a conflicting app. If fixed then find another keyboard app that you like.
When I plug my device into my pc I cant transfer any files:
Make sure the device's screen is on, and that the lockscreen is not showing.
My dock isn't charging my tablet above 97%:
There is inbuilt code to stop your device from charging above a certain point to prolong the battery life.
Solid Green light = Battery above 95% charge.
Solid Orange (they call it orange) = 10-95% charge.
Orange blinking = Battery less than 3-10% charge.
Orange fast blinking = Battery less than 3% charge.
My screen is sticky:
Give it a wipe with a microfibre cloth. After a few days of use it will be a lot better.
The XDA site is laggy in the default browser:
Bottom left of the XDA site is a dropdown box. Change the template to 'Classic' mode.
After trying to update the firmware, my device is showing the wrong build number:
Factory reset your device and re-apply the update manually.
I get a strange clicking noise on startup:
It's normal. This is just the camera running through the initialisation process.
I'm having troubles installing apps via the desktop market.

My apps are force-closing/crashing all the time:
Install apps that are known to be stable with honeycomb. Try this list HERE.
My SDXC card isn't working:
Format it as NTFS, if you are using files over 4gb on it or the card wont work properly. An alternative method is to format the card as Fat32 filesystem (if you are going to be only storing files under 4gb in size), but you will need to partition it into 32gb sections if you use this formatting system, for the full capacity to be usable.

My battery died very quickly while the tablet was in standby:
If you have wifi on when you put the tablet in standby, it stays connected. If you leave an area of wifi coverage, the tablet will continually search for a network, draining the battery.

You can modify that behavior in the wifi settings. Take a look at the sleep settngs.
I have not seen this mentioned so it probably is not too common a problem but my wifi was initially invisible to my transformer. Switching the channel from 13 or maybe 14 to something lower fixed the issue.

Yes, and I want to stress: wifi performance on standby is problematic and needs a fix. On the Xoom, wifi can be kept on when the screen turns off and standby performance is in the <.5%/hour battery use range. The Asus needs to have wifi set to turn off when the screen is off to achieve this kind of performance (otherwise, it burns about 3%/hour).
I'm hoping Asus is aware of this issue and will fix it soon in a firmware update.
some very good points, thank you
Touch screen stopped responding to touch
Brand new unit after about an hours use the touchscreen stopped responding to touch. It did this on Friday, May 13th, between Noon and 5pm eastern DST. The unit was working when shut of and was in a safe spot. I went to turn it on and no touchscreen. I noted the time as I think there may have been an OTA update then but I never saw anything on screen.
No monkey business, rooting, tinkering etc. Just learning about unit.
I have wiped the memory and cold booted several times, no change. I note that after a forced off the unit turns back on by its self. I saw earlier when I started the browser for the first time, the right 25% of the screen was over bright then went dark. Exiting browser, screen returned to normal and never saw this behavior again.
Screen may be somewhat dim now but cannot get past setup screen as only power key is responded to.
Already asked B&H for RMA but any magic gratefully accepted.
Howard
@easyrotor
Unfortunately it sounds like a clear case of a faulty unit. Don't know of anything that can help in that situation im afraid. Not what you'd want to hear of course, but at least it should be a simple exchange for a new one.

Good point, I'm not sure. I assuming that no matter what, the led on the keyboard dock would show just it's own charge.
Will have to monitor it for a bit and get back to you.
Hopefully later once Asus release another update, it will contain the dock battery vs. tablet battery (that got taken out from the .12 beta build) for us to monitor both.
just wanted to say that this thread is awesome...thanks so much for putting in the effort to document all problems/solutions that may come up with our TF's.
It might be worth mentioning light bleed here?

Transformer won't Charge
I received my eee pad transformer from hh gregg yesterday. When I opened the box I noticed that there was a scratch that appeared to be under the the screen. The scratch is very long, but also very fine and you can only see it when the screen is dark and you hold it up to the light. So I figured what the heck, not that big of a deal. However, when I went to charge the transformer, I cannot get it to charge. No light, no nothing. I've tried everything. Plugging it up to the computer, plugging into the wall, taking apart and putting back together, still nothing. I'm trying to figure out what to do. Does anyone know what could be causing this? Asus said I can send to them and they will look at it or I can send it back to the store, however, the store does not have anymore of the transformers in stock.

If you are taking apart and putting back together the wall charger then you likely haven't put it together properly yet; it will not come apart easily at all if it is fully together.
Try pushing harder than you think you should until the pronged portion is snapped in to place and you cannot easily remove it again. If it doesn't snap down, the contacts on the back side don't line up and it won't charge.

Charging led "broken" while phone phone is turned off

I have report on Jira the following issue.
The led in our OnePlus One doesn't lit when the phone is turned off and we try to charge it, it will affect most if not 100% OnePlus One user, the bug is reported by me using their official rom but happens almost in every rom I've tested(radio issue if you ask me).
Check it here: https://jira.cyanogenmod.org/browse/BACON-4187
The assigned person on this actually told me to stay quite about this and I'm like why??? and to be exact and not lying about it, he said: " I'm not going to advertise the issue (and I would rather you not either)". They want to hide this for some reason.
Some might say but why charge it while it's turned off? well if you are in a hurry every juice is needed, also why not have a "proper" phone? even Chinese no-name brands have this, it's basic function.
Please spread this and make an upvote so this would be solved asap(sure it's not life threating issue but surely I'd like to have it because why not?)
Can't say I have ever turned my phone off to charge it. Nor can I be bothered to even to test it.
I don't really see the issue, if you are turning it off to quick charge then you are in a rush and not fully charging it anyway.
Won;t the LED draw power and slow down charging *jk*
Just out of interest, does the power drain on startup of the phone not offset the tiny amount of power saved that the phone would be using when in deep sleep

If you plug the cable how would you know it's actually charging? ..to verify you need to press the power button once to check the battery level in the screen. People don't mind have problematic devices fine by me they deserve this
Me on the other hand? why not fix this, even if I rarely use it ..it's not rocket science and it was working when I got the device in the first place
P.S. "Just out of interest, does the power drain on startup of the phone not offset the tiny amount of power saved that the phone would be using when in deep sleep" Lets say you have 30 minutes to spend and you need to leave ASAP, turning off the phone will charge more than having the phone turned on in "deep sleep" ..phone still uses energy and some apps do run in the backround that you probably forget to close(we're only humans)
