I bought a second hand HD2, however it arrived with a third-party chinese battery. I contacted the seller who apologised and said that battery was a replacement because the original didn't hold a good charge, and he would send the original through the post. The battery however was fully charged so I flashed all the neccessary files and installed NAND Android (my reason for buying it in the first place), however today - the same day it arrived - I noticed that the orange charge light was going off, usually when the phone screen went off. This necessitated plugging the USB lead back in again, and within sometimes less than a minute the same problem would occur. I have checked the battery prongs, reset the the phone, changed USB settings etc and the problem persists.
Just wondered of I should be worried...I am unable to find an identical problem to this on the forums so I'm assuming it's not a ROM issue. I am currently using the Desire port from DFT.
Would a cheap Chinese battery demonstrate this sort of problem?
The seller says he never had an issue of charging the phone.
My next resort is to flash Windows Mobile back on, but I'm at work and a bit anxious so was hoping for someone with some experience to reassure me!
All USB syncing etc works fine...it is literally just charging that's the issue.
Maybe it's your USB that's faulty. I had a faulty usb that would go on and off sometimes too. However I don't see why the battery would affect the LED light, as the battery has to be connected to the phone for it to stay on, and so the battery can't be losing it's connection with the phone randomly, so it's either your usb cord, or the port.
Word of advice, don't let your phone lose power cuz of the faulty charging. I assume you know that MAGLDR doesn't let you charge the phone while off, so a dead battery in our case, is a dead phone. Happened to me once cuz of my usb, luckily there was still a small amount of charge left after i took the battery out and placed it back in.
It's definitely not the cable as I've used an official HTC charger with it which does exactly the same thing. I've also tried with a Samsung MicroUSB charger from my Galaxy S
Maybe it's the usb port then... That's the worst case scenario because you'd have to get the whole motherboard replaced...
However if in winmo you don't experience the problems, then it was just some software problems, so try a different radio and build, and see if they work.
Edit:
Or maybe it's the LED that's faulty. (never heard of such a situation but anything is possible) >.>
Does it still charge even if the LED is not orange/on?
Thing is though I can pretty much get it to stay charging if I don't let it lock and the screen go off? Could this still be a problem with the USB port? I'm getting worried now as I don't like the hassle of sending things back through eBay. I'm wondering if the seller bought a spare battery thinking it was just a battery problem and isn't telling the whole story. Foolishly I didn't test the device with Windows Mobile, I just went straight into flashing as I had put Android on my friend's HD2 the other day in exactly the same way...his is even an ex Virgin Mobile phone like this one. Needless to say, he is having no charging issues.
Dude dont worry , the problem is the battery ! i got two chinese battery ones and both cant charge with the phone, i have to use eksternal charger Dont worry the red and orange led flashes constantly when i try to charge it
Just buy a cheap charger from ebay , and buy a oem htc hd2 battery
Hi thanks for your reply. Mine doesn't flash red and orange though: the orange light comes on as normal and the phone reports it as charging, but after a while (seems to be when the phone goes to standby most of the time) the orange light turns off and the charging symbol disappears. If I unplug and replug again the light comes back on for a period. I've not tested thoroughly but I THINK it will stay charging when I leave the phone out of standby with the screen set to stay on for 30 minutes. I really HOPE it's a battery issue but it sounds slightly different to yours as mine does at least charge to a degree. I'm worried there's a blown capacitor somewhere on the logic board that's making the phone charge malfunction but obviously there's no way of testing until I get a new battery.
It concerns me that the seller said he had no charging problems...he must have been able to charge it somehow as the battery was full when it arrived...could I have burnt something out when flashing?!
Mine do charge to about 50 % and then it stops
Im 100 % sure its the battery becouse the battery has a circuitboard inside of it, and thats often messed up considering its made cheap in china . But test it with your friends hd2 original battery You can 2 see if the wet indicatior has been activated
the " white " paper next to the battery poles should be white and not pink, alltso where the skrewholes of the phone that should allso be white just to make sure your phone is not waterdamaget
I don't think flashing could have burnt something out. Overclocking and generating a lot of heat can burn something out though.
Didn't you receive the stock battery? Why not try it with that, and if the problem stilll persists then it might not be the battery. Either way, it will help you to test out the phone with a stock battery.
I tried it again after a few hours and it charged for a fair while before the light went off again.
I don't have the original battery as the seller has yet to mail it to me.
Does anyone else think it's worth me trying out a stock Windows Mobile ROM to see if it works? Might be that Android ROMs are less forgiving of cheap batteries with dodgy circuitry..
UPDATE
Ok so I've flashed Windows Mobile onto the device and wiped Magldr. The phone now alternates between a green and an amber light on the charging indicator. Looks like Windows Mobile won't charge it at all!
Does anyone know what this means?
I've checked for water damage in the areas mentioned and there is no sign.
Well your best bet is to send it in for repairs. But I'd suggest you test the phone out first with a stock battery.
Well I Only bought the phone yesterday so I certainly won't be paying for any repairs.
Got a replacement battery today - a genuine HTC one.
Plugged in, switched on....flashing between amber and green
I have a nagging suspicion this is going to be an eBay refund nightmare.
have you checked that the pins on the phone is not bendt? pins where battery poles connect to phone
problem solved? fingers crossed
OK so as a last resort I flashed radio 2.15 to the device. Seems that this has completely fixed the problem as without even restoring the phone is now charging properly. It seems that a corrupted radio flash had affected the charge somehow....at least I hope so.
The same problem has not come back again today at all.
Might be worth throwing this solution in a problems and solutions section as I haven't found any reference to it on the net and it might fix things for others panicking over their handsets.
That's nice.
Good for you, since it's a hassle to deal with sending back the device and shizz like that.
was just searching is anyone had a similar problem like me. to the OP yours sounds like my problem.
Had these fake OEM batteries for a while now. Until recently they have been charging ang turning off in 1 1/2 minutes. put a genuine OEM battery in and the problem is gone.
My solution was OEM can charge thru phone but fakes cant, use fakes as backup and charge it thru a desktop charger. goodluck
I just want you guys to help me diagnose the problem.
I was charging my phone yesterday with a cheap car charger.
My phone now produces lots of heat, eats lots of current (discharges quickly) and USB is not working (only charging).
I tried flashing different radios, kernels, stock rom and factory reset - didn't help.
Plugging a phone into Ubuntu PC doesn't add any logs about new USB device in dmesg, even in fastboot mode.
My questions:
1. What can cause SoC to produce heat and to discarge battery very quickly?
2. Is it a failure of a USB board or of the SoC itself?
I have two options on eBay: logic board and usb board.
It would be great to buy a 16GB motherboard instead of my current 8GB, but I want to address the problem with less money spent on it.
I don't know which one to buy.
same problem
Unforunetly I don't have a solution for you, I have been experiencing the same problem since last week. My phone no longer charges in AC mode, I can't connect it to any PC (fastboot doesn't work), and the battery is draining fast (from Phone Idle process). It is warm when the screen is off. I am on Android 4.3, it was working fine up until last week.
I'm about ready to RMA it, however it's interesting that I am not the only one experiencing this problem lately.

I'm not sure what caused it, I have a feeling it's similar to what happened to yours. I use a blackberry car charger in my car, and at work I use a non LG AC charger. So I'm thinking it was the car charger, but the weird thing is it has been working fine with both chargers for 6+ months.

Another thing is that I was installing a faux kernel 3 days ago, but it didn't cause these symptoms instantaneously (instead, it made my nexus super power-efficient), so I don't think that was the cause, too.
P.S. Google's RMA policy doesn't allow to return phones after 15 days, so I think the best choice would be to buy a broken phone and interchange the parts.

I haven't used any custom kernels or ROMs. I am rooted with custom recovery though.
There is a 1 year warranty on the phone, and I am within that 1 year so I hope to be able to get a replacement. This appears to be a hardware problem.
edit: Have you tried taking the battery out? In previous phones when stuff like this would happen I was able to pull the battery out. I tried to open my phone but it's a pain to pry open without breaking something.

No, but I will do this tomorrow. I don't know if this helps.
P.S. Sometimes I get this in dmesg:
Code:
[738145.499853] hub 2-1:1.0: unable to enumerate USB device on port 8
...which is not good either.
Well, I tried removing the battery - that didn't help.
What actually helped, is the following:
1. Bought cheap broken nexus.
2. Exchanged motherboard and usb board with my existing device.
3. Sold broken nexus for cheaper price.
4. ...Profit!
Now my nexus works again, and more than that, it has 16gb instead of 8gb. It wasn't hard.
I'm happy now.
2018 may be late in the game to become a new owner of a OnePlus 2 phone. But here I am. My main phone at present remains a Samsung Note 4, and I'm trying to get a feel for how this old (but not as old as the Note 4) phone can be repaired. My issues are a mix of battery, possible circuit board, and other problems / eccentricities.
The phone was given to me non-working. I have a minor-league reputation for rescuing phones, so thought I'd try this one.
First, I had to get it up and going. Nothing worked initially. I wasn't delighted to find out the battery is only accessible after removing two covers and about 30 microscopic screws. I reset it by pulling the small "plug" at top center-right and the phone decided to allow me to boot. I immediately (per instructions I found elsewhere here) went to fastboot and wiped the cache.
I did manage to install TWRP and the latest (as of a few days back) version of Lineage 8.1. But then the problems began again. The phone would suddenly, after charging for a while (and reporting a battery that was nearly charged), shut down. No charging icon showed on the screen.
Fast foward. Today, I got a cheap knock-off battery in the mail. It intially worked and I got it nearly charged. But after more spontaneous reboots I noticed something odd; in TWRP, the battery said only 50% charged while in Lineage it said 97% charged. So once again I wiped the cache and this time the ART/Dalvik cache as well (pointless, but ya never know).
This did get the two percentage reports matching up. And initially it got the phone working again. But alas, once again, the phone started the shutting down.
Currently, I'm leaving it overnight to charge - if in fact it is charging (how does one tell)? If that doesn't work, I'm thinking about using Odin to totally reflash the original version of the operating system.
Any other ideas or input - including laughing at me for bothering with this - is permitted.
I will say that the engineering of this phone compared to the older Note 4 leaves the Note easily the winner; to take its battery out is a matter of 20 seconds. Really not impressed with my OnePlus experience so far...
Thought I'd update things. After spending a day on sites (here and on the official OnePlus community boards) I tried any number of fixes. I'm reasonably convinced the only way to somewhat consistently start my particular OnePlus 2 phone is to:
1. Open it up, thus voiding the warranty (hehehe.... by now that's void anyway).
2. Unplug the battery's small plug at upper right-center of battery (a fingernail works fine, but do make sure the phone isn't plugged in!)
3. *Leave the back off* or at best gingerly snap it on but without attaching the screws. (Every time I did so, even after extensively using the phone while it lay on my sofa's arm and rebooting it numerous successful times previous to replacing the screws, the phone refused to reboot.)
4. I also cleaned the usb c socket with a wood toothpick and was a little surprised at how dirty it was; I did the same in a minimal way to the battery contacts.
5. I found no real use to having the actual OnePlus charger; I used it a bit but my best results came from the Samsung charger and a new (though cheap) usb c cable I nabbed via ebay.
Today I did get the phone going and intentionally wiped Lineage and installed the latest (2017) version of the OnePlus2 official os. It went on fine. I rooted it, installed apps, and (as mentioned) repeatedly shut down and restarted the phone, which promptly restarted with only a 3 second lag. I did this 5 times because one thread I found suggested this was an official OnePlus suggestion. (I rolled my eyes but did it anyway.) Played with the phone a bit, then shut it down again and screwed the back on. As noted, the phone suddenly wouldn't turn on again.
In summary, I'm not sure if this phone can be meaningfully resurrected. If I knew where what may be a short in it was, I could possibly replace that part. But I have little idea and am not quite the geek enough to sort that out. I am guessing at a short because without the lid or screws, it wants to work. It wants to be a good phone for me and I'll keep toying with it for a while longer.
Any suggestions appreciated.
Third post is a question for others:
Has anyone else experienced their OnePlus 2 working fine *without* the back cover screwed on, but as soon as it was screwed on the phone stopped working and wouldn't start again? And, if so, did they ever sort out why?
I'm going to make this a separate discussion.
Hey. I experienced the same symptoms with a "official" replacement battery I found online. Random reboots over and over again until I couldn't even turn it one anymore.
TWRP was always showing different battery percentages than OS.once I put back in my old but original battery that came with the phone it turned on again and it works flawlessly again.

This is something I've read, and may well do. It also, however, raises another thorny set of issues re battery calibration. I understand that sometimes new batteries have to be "calibrated" by being charged, discharged completely, charged again, discharged completely, and charged yet again and discharged. After that, things are supposedly going to run right. Trouble is in my case, the phone doesn't want the battery; it keeps stopping completely and not restarting. Either the battery stats are wholly inaccurate (says around 57% charged during those brief times I've had it up) or I need to go with your idea. Trouble is there the original battery from this phone is dated 2015; I hope it has anything at all left to give.

I'm trying this in desperation. The phone has gone completely unresponsive at this point, and I'm looking at having a technological paper weight. Hope I can resurrect it but the odds are not good.
Some progress, some regress.
Here's what I'm seeing. I can get the phone up and running again after extensive recharging. As long as I leave the back of the phone off - that is, both the inner and outer backs - it seems willing to keep running. As soon as I snap the inner back into place, not even with the screws yet, the phone locks up. Soon after, around 10 to 20 seconds, it shuts off. Sometimes it will restart and other times it won't for a long time, even after unplugging and replugging battery.
Has anyone else run into shorting or grounding issues associated with the back (inner, the one w/ 18 screws) case?
I am now back to a dead phone. A new (3rd party) battery is my current hope... charging it for over a day now has not yet led to the phone showing any sign of life.
One other question: I know both this cable and charger work, but as they are not the "original" OnePlus charger / cable combo, could that be the difference? I'd appreciate it if there is any clear evidence regarding this question.
The below article raises a disturbing possibility, based on the reality that OnePlus cables and chargers are - by OnePlus' own admission - non-standard and possibly could harm other electronics. But on top of that, and not well explored in the article, is whether or not OnePlus' charger/cable combo might even be damaging to the OnePlus 2 (and other OnePlus phones). They "assure us" this is not the case. Hmm.

I thought I'd update this thread with what may be the final installment.
I invested $70 in a highly bent but somehow still working second OnePlus 2 phone off ebay. (The guy had a great fall on a log story as to how the phone got bent.) Long story short... I gambled and won. That is, I gambled that the innards of the second phone would go into my first phone and that the first phone's screen would work. YES. And so, after playing amateur phone repairman, I have myself a OnePlus 2.
So many questions. Going to peruse this board now...
Hello everybody
Phone: Motorola Moto 4g Athene. Bought in 2016 in the USA in BestBuy. There is no warranty now.
Firmware: I have used LineageOS. At the moment, the bootloader is locked and the firmware is official (see below)
Problem:
The battery indicator shows 0%. The application "Battery callibration" shows 0mV. I culdn't turn it on directly: after "hello moto!" it is turned off. I managed to enter the system only through the recovery. If you disconnect the charging from the phone, it immediately turns off, because it thinks that the battery is critically low. At the same time in the recovery it works as long and stable as need even without charger. The voltage at the ends of the wires of battery measured by the multimeter was 3.9. After the body stood on the charge it became 4.2. Looks like the battery is charging in normal mode. All other functions of the phone seems to work properly. It seems that the phone is OK, but for some reason "does not know" how many volts there are on the clamps of its battery...
Background:
The body is Motorola Moto 4g Athene. It heated a lot all the time after purchase. As a result, the official battery have dead after one year. I bought a new one from the internet. (I am not in the US now. Motorola do not certified here. So there is no official parts, stores and service centers). The new one also died in a couple of months. During the replacement of the third battery, the plug on the board broke off. The wires from the new battery had to soldered directly to the board ... The third battery also died in a couple of months, and I have bought a fourth. Soldered. Here this funny Bug appeared.
Attempts to resolve:
Initially, it was LineageOS 14.1 installed. I did a Wipe of everything except internal data. Nothing changed. Then I rolled back to native firmware with locked recovery. Nothing. I made a Factory reset. Nothing. I have resoldered contacts from the battery wires to the board 5-6 times. Nothing has changed.
There is an idea that I overheated something on the board. Charge controller or something else. Nevertheless I can’t understand why the body works normally, except that it does not understand how many volts there are in the battery?
As a temporary solution, I consider the installation of some kind of software, which would not allow the android to turn off when the battery is low. In this case, I will charge the phone every 15-16 hours and everything will be OK. Do you have any idea about such kind of software?
Any other ideas are welcome.
Please can someone help me with a problem I’m having with my Samsung Galaxy s5.
I put my phone on charge before I went to bed and when I woke up it was still showing a red LED. I knew this was wrong because it should have had enough time to charge and turn green. I had not powered the phone off before putting it on charge and I plugged it into the same USB 3.0 charging lead I have been using for the past six months. I unplugged the phone and pressed the power button to light up the lock screen but it didn’t light up.
I’m thinking possibly something has either shorted or over heated and fried something either on the charging port assembly or one of the chips adjacent to the port while the charger was plugged in. It seems like only a trickle of power is getting through to the phone. When I plug a different USB 2 charging cable into the phone, without trying to power on, the charging icon appears but shows no charge at all in the battery.
I have also tried the spare battery I have but it’s still the same. I know the spare battery is 100% fully charged because I store it in a separate charging/storage box which shows a green LED when it is full. In fact the one which was in the phone at the time is also fully charged according to the charging box. Neither battery has got warm at all inside the phone. I’m confident both batteries are fully charged and totally fine and the problem isn’t with the batteries.
At this point I removed my sim card and also the MicroSD card. I needed the sim to use in my spare phone and I wanted to see if the sd card could be causing the issue but after again trying a normal reboot it made no difference.
I’ve tried several possible things I found on google but nothing has worked. Between each different thing I tried I had to remove the battery for 10 seconds and insert it again to get it out of the boot loop so I could try something else.
Initially when I tried booting into safe mode, then recovery mode and then download mode it brought up the screens for those but in each case after a few seconds the phone powered off and went into a boot loop so I couldn’t attempt any recovery options such as clearing cache etc. Now I cannot even get it to start any of those modes at all and all that happens is the phone does a little vibration, displays the Samsung logo and then just boot loops no matter what I try.
I have tried removing the battery and leaving the phone for a few hours then powering on again but it still just loops.
I have tried pressing and holding Vol-down when plugging it into my PC using a different USB 2 cable and windows acknowledged a phone was plugged in but said it couldn’t connect or recognise the phone and suggested the phone could have a fault.
I don't know if maybe my USB 3.0 lead has a fault that could have caused it or if there could have been some electricity spike while the phone was plugged in, or as I said a component has just fried.
I strongly suspect this is a hardware fault and not a software fault but as I’m not a phone engineer I have no idea about how to trace any possible hardware issues or what might have gone wrong. I would really appreciate any help or suggestions about what the problem might be as this has been a great phone for the last 2 years since I got it and I’d be sad to have to junk it and buy a new one.
Thank you.
I would not junk it yet......
You had mentioned that you go through a lot, just to get phone into Recovery ( " Initially when I tried booting into safe mode, then recovery mode and then download mode it brought up the screens for those but in each case after a few seconds the phone powered off and went into a boot loop so I couldn’t attempt any recovery options such as clearing cache etc. Now I cannot even get it to start any of those modes at all and all that happens is the phone does a little vibration, displays the Samsung logo and then just boot loops no matter what I try." )
OK, just my 2 cents here on this... Why not trying to goto Recovery by pressing and holding the Volume Down (vol-); Home button, and The Power button all at the same time. (yes, if you have a Recovery, and its works, you should be able to boot right into Recovery- >Now, (I would, cause I've been there..) I would also have a PC going with Odin open (Plus the Latest Stock Rom) ... If it works, you would flash the Stock ROM, to clean up anything, giving you all stock, but you can change that of course ...then go from there...
Second, if you can not still get to Recovery.... Have you tried a Stock USB Cable, only asking.... Obliviously something is a miss... with Power... IF phone is off, and you plug it to a power source ... then system has power, and these can power up with just the usb cable, without having the battery in..... Been there. Can add the simple fact, if using just a Micro SD cable, they can bend the Power Board. Believe me (Had to fix the Wife's S5 a few Frinkin' times....) That is why, I say using the Stock Cable, or even a USB 3.0 Cable (like the stock one) does help with power issues when the Micro has bent up the power board...
Will check back and see if this may have you to Recovery or fixed... sure hope this can help you out
Thanks for replying godofsalt.
At the time the phone was plugged in to my USB 3 lead which charges faster and all I can think is that perhaps there could be a fault with the lead or the higher ampage of using this lead caused a circuit to burn out.
I have around a dozen USB 2 leads and I've tried your idea with 3 different ones but none of them will fire up the phone at all with the battery taken out.
I am sure this is going to need some kind of replacement either of the charging port or the motherboard. I don't rate my chances of trying to do it myself and I don't think it will be economic to take it to a shop so I've found a better option by buying the same phone which is second hand but in good condition. That way I know I have all the additional accessories already for probably the same price any shop would charge to fix it.
In future I'll stick to using a decent USB 2 lead on the 1 amp charger I used to use before and hopefully this will not occur again.
G500F battery graphic/boot loop
Had the same problem a few days after installing a 9.0 Rom. My battery is brand new and all cables aren't too aged, so I thought this had to be a physical fault of some kind, but then I had the thought to flash an older bootloader and just like that my battery started taking a charge again and I could boot up. Switched to Flyme os for a while the went back to 9.0 again, with the lastest bootloader and the thing stopped working again. Don't know too much, but I'd try and flash a different bootloader to see if there's any difference. My device failed right at the Galaxy logo, then looped the charging graphic endlessly but would strangely go into download mode and not fail. Don't know if this helps, just thought I'd share my solution.
Thanks for replying henderia93.
My symptoms are very slightly different in that the phone couldn't maintain any of the modes I tried for more than a few seconds before going back to the boot loop again so there was no chance of trying any software fixes including flashing the ROM. Now it won't enter any of those modes at all. I'm certain that's due to only a trickle of power getting through to the main board, not enough to maintain any recovery modes, so there is just enough power for it to attempt to boot, but no more so it just keeps looping, most likely caused by something that has blown while on charge.

I ha e taken so many of these a part... Like I may have mentioned, there is a Board, just for the USB (data and power (i still have 2 of them)).... In short, you really have to pretty much take the phone a part. Being very careful with the Screen, and the "Sticky" LEDs and the Home button. There is a lot to it actually.
Like I said, been there done that... Cheap to get, takes some time but it is possible to replace that board. It's a separate board different from the actual main CPU board.
I would have to find it, but I had a manual, for taking these a part.

I ha e taken so many of these a part... Like I may have mentioned, there is a Board, just for the USB (data and power (i still have 2 of them)).... In short, you really have to pretty much take the phone a part. Being very careful with the Screen, and the "Sticky" LEDs and the Home button. There is a lot to it actually.
Like I said, been there done that... Cheap to get, takes some time but it is possible to replace that board. It's a separate board different from the actual main CPU board.

While I've been looking for answers about this I've seen teardown videos for the s5 so I can see what the port assembly looks like with it's little PCB behind it. As I have a replacement s5 on it's way all I need to decide now is whether to keep the old handset for spare parts or see if I can follow the teardown video to try and install a new port assembly to get the phone working again as a spare.

Yep, me too, seen many vids on the tear down. I decided to go a bit more, IMHO, to have an actual manual, PDF, when I did my first one, many years ago. So, can read, and use photos wisely. Seen too many Utube crap, where the break it, destroy it..... crazy!
Well, at this age, not too sure what to do my self. In our case, our present service is cheaper to Keep these. Grandfathered in, and we pay a but less, than going to any other carrier. Plus, these newer phones are not cheap at all.
True, it up to you. hope all goes well.
Sorry I am a novice so please excuse my question.
Are you assuming that the usb port is shorting even when no usb cable is inserted? As you put a fully charged battery in with no change it would seem that the act of charging is not involved.
Have you tried a voltmeter to check the voltage at the battery charging pins?
Have you tried to check the voltage at the two pins commonly used for a wireless charging adapter (to the upper left of the battery) to see what the voltage is?
Sorry if I am off base.
