Wifi causing Universal to turn off

as i said in the title when i use wifi i get a about 2-5 mins of use out of it, but then it will cause the pda to shut down, even when i have full battery and its plugged in, and it wont completely turn back on till i plug in a charger, occasionally even this wont help for a while, i also have had some problems with the battery, like sometimes it wont be recognised by the pda so it wont turn on and will show the red light when i try to charge it, could that cause this problem?

Sounds like new battery time.
My last one used to die if I had the backlight on for more than a few mins, it lasted a year (the original battery).
Got a new cheap one from eBay, seems to be going fine with good battery life.

thanks i thought this was the problem so i bought a new battery last week, still hasnt come yet though

Hi
i have the same prob too, but when i plug it into the charger it won't turn off!!!

this is an actual common problem possibly residing to a specific batch load or maybe more. the problem will get worse and in short it's not a battery it's a mainboard problem with a sensor or a part that becomes hypersensative to heat. I think it's part of the same circuit that shuts the device down if the cpu or battery overheats but I can't proove it yet. I've had 2 of these phones so far. 1 3 got t-mobile t swap for an mda vario 2 at the time as the phone wouldn't stay stable for more then a few minutes. same result with 2 like 4 like replacements they sent me. ifinally said enough I want the closest thing tech spec wise to it. the 2nd one was my wifes which she barely used now that shes moved on to a different phone I've started playing a bit with it as it's over 12 months old. and I put it back into the box and up on a shelf as soon as it started doing the rebooting thing like the first one. NO WONDER ORANGE START DISCONTINUING IT AS WELL DID T-MOBILE UK.
UPDATED :
After reading a few of the posts aftr mine, I set out on a mission to determine the more exact reason for this cause. I found the unlike most mobile e.g: sony, lg, nokia etc. this phone would nout power on from the mains adapter without the battery. I figured initially it must have been the manufacture thinking this is not a laptop and the mains adaptr was intendd to charge batteries and then run the device. this also prevents data loss or file system corruption incase your mains charger comes loose from the device while playing. however I found that by putting my finger (when your finger tips are lightly moist and conductive) over the battery terminals on the device it would infact power on and work. now in light of this there are 6 terminals to make conduct with the battery the outter 2 on each extreme end are your + and - . the 2 inner ones are likely then to be battery voltage sensor and battery temprature.
so I said great way to test a theory. I unplugged the mains charger and started downloading files from my pc to the memory card over wireless. this of coarse caused the battery and the device to heat up very quickly. within about 10 minutes it did as expected and shut off. then when pressing the power button could not make it back to the main today screen either it would shut off on the windows mobile splash screen OR it would shut off during the first splash at bootloader.
I then removed the now very warm battery and put my finger on the battery terminals making sure the 2 center pins were touching my finger. voila th device powered on and booted up just fine. I then went back to doing file transfers and it never shut off on me again as lon as I held my finger on the battery terminals. in short I fooled it into thinking the battery was there but but that the temprature was fine. wm6.1 from ranji's 7.1 could tell there was no bettery to charge but the temp sensor was fooled. conclusion: the reason 2 replacement handsets in the past sent to me by t-mobile conitune to fail was not infact an internal problem that was main board related it was the battery incorrectly sending wrong temp info or a faulty battery that was getting to hot and the manufactures own safty device was shutting the device down to cool off the battery. this would be why in the past I would be able to just leave it off and eventallly it would work again. I felt like such a fool but at the same time I felt good that I got 1 traded for a vario and that now all I need to do to fix my mda pro is t get a new battery. I am man enough as you can tell to say wheni was wrong and I was. in light of this new info I would recommend the device to others but if you start getting random shut downs and turn offs during internet over wireless or gprs and the device is wamr ask your provider for a new battery or replace it yourself maybe even with a larger capacity one as it will likely resolve your problem. I know there are other posts i've done about this subject and I HOPE that those that have read them read this update as it applies to all htc universals regardless what branding they fall under.

Nexus 5 won't charge the battery, shows -30degrees and cold temp

Hey All,
i have a nexus 5 running android 5.1.1, which recently i have encountered some battery issues, the battery drained very fast (6-7 hours from 100% to 0%).
but then, it stopped charging the battery, no matter what i changed - nothing worked! (new cables, different chargers and so on).
yesterday i have bought a new battery and replaced the original faulty battery, but nothing is changed, the new battery won't charge.
i tried to charge it when the nexus is on or off, doesn't matter, same result...
i am very frustrated from the situation, and basically can not use the nexus any more..
one more thing, i tried also google suggestion (when the cell is off, to press power+volume buttons, and then scrolling down to shut down and inserting the charger - >didn't work for me).
i tried to upgrade to Marshmallow (6.0.1) but there is not enough battery power to allow it...
when i dial *#*#INFO#*#*, and check the battery properties,
why the temp is always -30 degrees for the two batteries?
Is it a sensor issue?
do you have any suggestion?
Thanks!

anyone?
i will really appreciate your suggestion..

Connect the phone to a Windows machine and look to see if any new devices appear in Device Manager.

Thanks for the reply.
I connected the nexus to my laptop, it was recognized and i could reach the storage, but the battery remained the same, not charging ..

So the nexus 5 appears in Windows explorer? Possible charging port problem?

well, maybe. havn't tried it so far..
have you encountered this issue of wrong temp alert of -30 degrees for other users ?
and replacing the charging port solved it?

I haven't encountered the battery temp issue.
Since the old and new battery behave the same way, there wouldn't be too many culprits which is why I mentioned the USB charging port. Has the ever been dropped? Any way you could test the batteries in another phone?

the problem was resolved!!!
finally, after so many hours trying to make it work, i encountered a thread here in XDA which explains that the sensor is located on the cable connecting the battery to the motherboard.
Apparently it was a bit loose, so i put something above the connection and put the cover tightly.
then, the temp was reasonable again and my nexus was coming back to live!
:laugh::laugh::laugh::laugh::laugh:

Same problem

Hey, I have the same same problem , what did you do to fix it? I've been almost a year without using my nexus because it only works when it's plugged. Can you tell me what thread did you read or the solution? Thank you

See my last post....
Anyway, The problem was at the connection port of the battery - when you remove the nexus cover, you will see that the battery is connected by a connector with 9-10 pins to the board. Apparently those pins weren't connected properly and were loose, so I put something from above to make some pressure on the connector, then screw back everything and close the cover. Since then, my nexus is working great!
I hope it will work the same for you...

Galaxy S5 Quit Taking a Charge

I'm trying to troubleshoot what might by wrong with my S5. I woke up the other morning and my phone was completely dead. It was plugged in, but no LED was on and the phone was not responding.
I've tried he various troubleshooting that I've seen around the internetz, such as:
removing the battery / discharging with power for 1 minute...plug back in and try again
use a different charger / cable
clean out the charging port (I used my air compressor to blow out any dust that might be in there)
I feel like I've exhausted all I know how to do. I do have another S5 coming in a couple of days, so I'm hoping to use that to see if it's either:
a problem with the battery
a problem with the charging port
something else?
My guess is that if the new battery comes in and I put it in my old phone, that will help me tell if it's the charging port or not, correct? My assumption is that if everything else is fine, then my old phone should power on.
I am a little nervous that it's something else though; I measured the voltage out of my battery and it was registering nothing the other day. When I plugged it into the phone and allowed it to charge (even though there was no indicator and the phone would not turn on) I measured the voltage again and it was registering ~2.8V.
Anyway, thanks in advance for anyone here that can offer any other guidance as to what I can look into to troubleshoot what the problem might be.

I've verified that another battery allows my phone to boot, so my guess is that it's the charging port.
How hairy are these to swap out? Is it a realistic repair?

ive cracked an S5 apart, and getting to the charge port isnt so bad if you can get the back plastic cover off, but you might have to remove the screen too. The S5 is waaaay harder to get apart than the early notes

You can get a wireless charging receiver or an external battery charger to charge you battery instead. I charge mine wireless as much as possible to help save the charging port for when I actually need it.

INTERNALS - N5 Power Routing

Recently disassembled and replace the original battery but have been having issues with the reassembly. Battery indicates charging and wireless charge status but does not hold. N5 must be powered via USB/external batt. and instantly powers down upon disconnect.
Is anyone familiar with the internal components to troubleshoot this issue? Ribbons look properly connected visually, however there is obviously an issue. Maybe a internal ribbon pinch/break somewhere?
Please reference photos to indicate how the charge process works, much thanks!
Beers on me for the genius with the solution

Are you sure the replacement battery is good? What happens when you put back the original battery?

Original battery does not work either

Did this problem ever occur before changing the battery? Do you have a way to check to see if the replacement battery is working properly such as trying it in another Nexus 5?
I'm admit that I'm just guessing. I've changed the battery many times on the Nexus 5 using 3rd party and OEM batteries but never experience what you are experiencing.

Unresponsive / Dead Phone - Any ideas?

So i recently picked up an XT1254 for a great deal. The phone is pristine, not a scratch on it. It looks brand new. It is totally unresponsive. If I plug it in the light on my charger turns from blue to green, telling me it's fast charging. But nothing from the phones LED. Also if I place it on a charging pad, color changes as well. I tried both options over night and still nothing. The phone does get warm (usual amount), leading me to believe it is charging the battery.
Holding the power button - nothing (no vibration, no moto logo, no LED responce)
Holding power + vol down - nothing ( = )
USB to PC - phone is not detected at all (I have ADB and current moto drivers installed)
I opened it up, and everything seems to be in order. No loose connections, no water damage. I checked the battery, and it reads roughly 2.5 volts across each pair of pins. Should it be reading 3.7-4 volts across each pair?
I unfortunately don't have another phone to check the MB, battery and LCD against.
I don't have a SIM installed in it, but I doubt it makes a difference?
Any ideas or advice would be greatly appreciated! Thanks-

Quite low for li-ion/-poly, I don't think it ever sees 3v or under in normal circumstances. It might be well into "damaging the battery" territory at this point, and it should certainly be higher after charging it for a while...might be a goner.
Have you tried removing the battery completely and running it off the USB cord? I would expect it to, if nothing else, bring the screen up complaining of a bad/missing battery. That said, I've never tried unplugging mine to see what happens, so no real idea.
I would suggest trying to fabricate a factory cable (which would provide power directly, ignoring battery status), but I don't know if post-OMAP Motorolas are physically configured to use them. If they aren't, it'll do nothing at best and burn up traces at worst : \
Also, holding Vol - while plugging it in should bring the boot menu up, regardless of available battery charge (therefore serving as a quick test to see if the power button is the problem). But that might go out the window as well if the battery is deader than a doornail.

It doesn't. When I fresh-install a ROM, I remove my SIM card to make sure none of my data gets used before I can turn various unwanted syncs/auto-updates off. The phone doesn't care at all, and nowadays Google isn't too whiny about a missing SIM either.

Hello guys.
Sorry for reviving an old thread, but I have similar problem with my Droid Turbo. During the replacement of the battery and speaker, I noticed oxidized resistors near the proximity sensor (which wasn't working since the purchase of the phone second-hand). I have cleaned the oxidized residue with ethanol and assembled the phone. After pressing the power button, the touch buttons light up and phone was vibrating every 20s but the screen was blank. So I disassembled it again to check all the connections but everything was fine. Since then, the phone won't even vibrate, just heats up a lot after holding power button. I have tried both batteries, speakers and also powering the phone without battery (only power cord connected). Both batteries are shoving around 3.8V.
Do you please have any suggestions how to fix the phone? Or should I assume that the motherboard died?
Thanks
