Empty DHD not charging, not powering on, no led.

Hello people
A couple of hours ago, my phone shut down due to empty battery. I came home, plugged it in and booted it, all was fine. At about 60% I shut it off and went to have lunch, when I came back and tried to turn it on, I couldn't.
Led was orange at the time, I unplugged the power cord but the led stayed on! I removed the battery to be able to reboot it, but when I re-inserted it I still wouldn't boot.
Now no matter how I try to charge it, led stays off like it's not charging. Tried various different cables/chargers, the same. Tried to plug it to the charger without battery but no led flashed. Tried to boot without sim/sd card, still the same.
Any ideas?
My battery has never been changed (for a year now) and has had a bunch of full drains. Could this be a dead battery? :/

Well seems the phone is fried... I tried two more official batteries and no go...

Sorry to hear it. I thought that at first when I read your thread but I thought because I am not the most experienced person here, there might be some kind of fix.
HTC will most likely if not certainly replace this handset for you, seeing as it just happened out of the blue.

Well I certainly hope so, problem is I suspect it's an import (from another European country) and local HTC service generally does not do well with European imports.
Anyway I'll give it a try, meanwhile I'm getting a sensation soon

I have a similar problem.
I'm lucky that my girlfriend has the same handset as I do, the I could compare the phone abnormal behavior tho that of her properly working phone.
The first thing I've noticed, after a while when the charger was attached, was that the phone is very hot and that the battery keeps draining out in a surprisingly high rate.
After a while I've noticed that even when the phone is turned off it wont recharge. Sometimes the Orange LED is on when recharging while it is off, and the LED stays on for a few seconds after removing the charger, as if it was still charging. Note that the affects of connecting the charger to the phone, are mainly the ones listed below (not necessarily altogether)
* The phone indicates as if it recharges.
* Going to an infinite loop of rebooting and crashing.
* Getting hot when power supply is plugged, or at any time when the phone is turned on.
Ultimately the battery was empty, and the only way I had to keep using the phone (mostly to diagnose the symptoms listed here) was to swap the battery with the one of my girlfriend's device, and charge my battery in her device while using her's. That's the place to mention that the battery works just fine and that the phone is draining any battery, no matter what.
I took it apart to have a closer look at the source of all of the heat emitted while the phone is turned on, and it seem to come from the motherboard itself.
That's all I have.
The worst thing is that a friend of mine who helped me opening it up broke the pcb of the volume keys. Now I checked and It turns out that that pcb is actually part of the flex cable, which sort of extension of the motherboard and is mainly the second most important piece of hardware of all the phone parts (not that there are so many). If I would be able to expose the conductors inside the flat cable I might be able to solder an alternative volume pad I'll make out of old some miniature switches I have. The cable is very thin. any Ideas of how to expose the relevant conductors without ripping the cable apart?

Just a (late) update:
It's been almost two years, I had given the phone to a close friend of mine after a couple of weeks since writing the first post, just in case he could resurrect it, nothing.
Then, a couple of months down the road, the phone suddenly woke up! He tried to connect it with the charger, after months of not being able to charge or boot it up and somehow it worked. And it has been working flawlessly ever since.
I just got it back to give to my girlfriend until her sensation is fixed, flashing Viper now
In case something like this happens to any of you, don't give up!

[Q] Charging Problem

Hi Guys,
I had a mishap with my desire hd..Water Damage..I have dried it out with the rice trick..
It comes on and everything is working..the screen is a bit blotchy but I can live with that..
The problem I have got is that phone will charge no problem.However once I disconnect charger the orange led stays on and the battery icon still shows as charging.I have tried different battery apps and they all say it is still charging even though it is not connected to charger.
Has anyone else had this problem..
Many Thanks
Dave

Did you try remove the battery while charging?

The battery seems to charge ok via usb lead...However when it is disconnected and I am using phone the battery icon still indicates as it is charging and the usb icon remains on the top as if it thinks that the phone is still charging and connected to usb...

could be something been damaged by the water
but have you tryed factory reset and see if it fix the problem ?

I have even tried different rom.All with the same result..I wonder could it possibly be the battery itself that is causing it..???I have ordered new battery just in case the water has damaged the battery in some way..Although it is fully charging it may be possibly causing the charge indicator to stay on ...

Just tried new battery.Still the same fault.....Any Ideas Folks....

Yeah i didnt even got the solution yet .But i notice that problem doesn't occur when charging through pc but it charges slowly.I also tried factory reset and even battery calliberation but nothing happened.i will take my phone to care...

HTC desire 816, ! mark while charging.
Experiencing same issue. Tried different charger, no help.
I dont prefer pc charging as its slow and phone discharges quickly.
Any workaround or any solution?

Sounds like some fault in the battery circuit that is limiting charging current. I think a PC uses anywhere from 100 mA to 500 mA but a charger or USB port wired to AC outlet can use 1 A or more. I wonder if advanced wiping of cache and formatting internal data would reset it?

are you using Customized ROM or Stock..?

Did you ever figure out a solution to this issue? My phone is doing this exact same thing and it's super irritating.
I bought a new battery to try replacing it and see if that helps, but I am not a phone tech and don't know about taking the back off of this phone to replace the battery. Hoping someone might have a different solution or at least tell me that changing the battery will in fact help (and then I'll go to the trouble of doing it).
ETA: My phone hasn't been rooted or anything. Was working completely fine. Still works fine except for this charging issue.

It's not that hard to remove the back cover. The plastic is very durable so you can't really break anything. I think there is a youtube video and a few descriptions here on xda. Basically you start @ the SDcard slot using some sort of pry tool to pop the plastic cover off as you go around the phone. Just beware that they use a lot of sticky tape on the bottom half of the phone so it takes a bit more effort to get the cover off. I used old credit cards for my pry tool. Some cut up into strips and other time a whole card to break the sticky tape connection.

Charging Problem
i am having same issue since last day....
i tried full wipe and installed a new ROM and it still having the same issue....
i m out of warranty and any way to fix this issue other than HTC official service..?

I have the same problem. Did anyone find a solution? Would a battery replacement solve this frustrating problem?

Z5 Premium won't turn on

Z5 Premium not turning on
hello everyone,
PLEASE HELP ME!
My z5 premium was working fine.. battery was charged too, and suddenly it turned off, and it didn't turn on back again. I've tried all the different ways and solutions that should turn it back on:
hard reset didn't work
2 minutes hard reset didn't work
hard reset button didn't work
plugged it in using it's OEM charger and usb cable didn't work either and LED didn't lit up
plugged it in to the computer nothing happened, wasn't detected with no sign of life
I had to take off it's battery cover (using professional tools) unplugged the battery, connected the phone to the charger while the battery is unplugged, and nothing happened reconnected the battery back, and plugged the phone again to it's wall charger, and no sign of life.
i left it there all night long since the afternoon. and when i came back in the next morning to check if the phone is charging and the LED is lit up, but again NO SIGN OF LIFE!
(BTW, the phone is in mint condition and it was never been disassembled or repaired)
Please if anyone have an idea what this could be?
if anyone has encountered the same problem and went through the same of what I've been, and was able to repair it or find a solution PLEASE LET ME KNOW!
Now, I'm thinking of 2 things: either the battery is completely dead(damaged) or it's the mainboard which I don't hope to be.
PLEASE LET ME KNOW YOUR THOUGHTS ABOUT THIS!
Now, forget about any sort of software repair, as I explained above, the phone didn't succeed in that.
So, any help or suggestion would be so much appreciated.
Thank you all for taking time in reading and participating in this topic.
Have a good day.

Not happy reading this thread. Why so many issues with Sony Android... Anyway;;
- I recently had the same issue - or an issue in the same ball park. Phone Just died and refused to charge, but would show a red LED and try to boot when plugged in.
- Sent it to Sony, Hoping it is only a dead battery
The OP sounds like a they have a USB port issue or a board issue, also OP phone will no longer waterproof after removal of cover.
Unclear as to whether you have tried the following;
- Turn on whist holding camera button instead of Volume up/down. it is worth a try
- Try to grab an official sony charging cable- basically impossible to buy nowadays, maybe a PS4 controller cable? try it

My stock unrooted Z5p died like this in April. Have the same issue as the OP and tried all the same solutions. My Z5p had only been used indoors for months with WiFi before sudden death. Replacing the charging port did nothing. Using the OEM cable and charger with a new battery gets a 2 sec red light when connected to power and starts booting up until the swirls (gets past Sony Xperia and powered by android screens). Then the screen goes dark and shows the big battery for a couple of seconds.
I didn't realize there was a sudden death problem with Sony phones until I started trying to fix this. What's even crazier is that I had (have) the Xperia Z, Z Ultra, and the Z2. The Z2 was used in the rain constantly and even survived an ejection from a handlebar mount at 15mph onto asphalt. (All these phones were rooted and using custom ROMs/kernels.) Seems like Sony has a serious QC issue they're not taking about.

Fast charging frying phone.

I plugged in my Zuk Z2(plus) into a charger yesterday happened to be a fast charger QC and within about 10 minutes it went up in smoke charger seems fine (cable melted) but the phone now only shows the ZUK logo and switches off,
Doesn't seem to charge either just vibrates, from the looks the charging ports a bit melted, Was lucky it didn't properly catch fire,
Anyhow to the question, I can get to (stock) recovery and I imagine I'll need a new charging port, but anyone know if the motherboard is likely fried too or would I get away with a new charging port on it ? (and obviously never charge with a QC again) .

I had the same thing happen to me. I was charging my ZUK in another room using a Quick Charge 3.0 charger. I went to check on it. There was smoke coming from the charging port (which was scorching hot) and a horrible electrical smell. Phone wouldn't turn on. From what I remember it was just a white LED when pressing the power button, maybe the vibration too. I tried to charge but it wouldn't do anything. Couldn't boot to EDL mode. I thought it was dead.
A few days later, I remember plugging the phone into my laptop (in another attempt to diagnose the problem) and at some point I got distracted and left it plugged in. After about 30 minutes I was suprised to see that it randomly powered on by itself and came back to life. I believe I still had trouble getting it to charge, and that the battery percentage was stuck on 0% when when plugged into the mains. But eventually it all just fixed itself and I have been using the phone for another 2 years without issue. Guess I got lucky.
Sadly it sounds like your phone is a little more damaged that what mine was. I did not have any visible damage, it was just a bad electrical smell that remained for a few weeks or months. I have heard from other people who had this problem and I believe there is a little component on the motherboard that overheats and burns out when trying to use a Quick Charge mains charger. But the phone works fine without it. I know the charging port is fastened to the motherboard so it would probably require soldering.
Example of replacement - Try looking on other sites like AliExpress: https://www.maxbhi.com/charging-connector-for-lenovo-z2-plus-32gb-zuk-z2.html

Don't I remember people hacking "the fast charging chip" off the board to fix this problem? Literally prying the chip off and it sorting this issue out and allegedly the phone working well. Try a search for something like that.
I know this was a common fault with fast chargers killing the phone.
