Device: HTC One (M7) Stock ROM
A few days ago, my never rooted, stock firmware, no unlocked boot loader, no custom ROM, never dropped HTC One (M7)'s battery died. Plugging in the charger had no effect, absolutely NOTHING. Tried 6 different cables and 9 different locations to charge it, nothing. Waited a while, dying in desperation. Then after so much of panic, I plugged it again, and randomly it started charging. But the charging had a loop - showed a bright orange LED with the power symbol on a battery for about 5 seconds, then a dim orange LED with the green battery charging, and a number, for about 10 seconds. The loop kept repeating. Eventually I could turn it on till the (incredibly low capacity) battery could live. So I did about 10 resets to it, and the situation would not improve.
Since my phone just decided to do this to me just before a long journey of mine, I was quite upset, and eventually infuriated to the limits. I decided to take it along and try different things to it - tried, tried, cleaned the ports, searched the net, nothing.
One fine day it decided to break the loop - now it charged, but only when off.
And today again its started the loop.
And here I am, begging for some help. I'm starting to hate this device now. Please help me.. :crying:
P.S. : I played a lot of Clash of Clans on the phone - it heated up a lot. Hope the info helps (Possible corrupted overheating charge instructions of the phone,etc.)
please help i love this phone cant lose this at all

I am having the same exact problem right now. its very annoying. I have to drain the whole battery to charge it again. and its in that loop that you mentioned. plus it does not charge when you put it on charge when its on. it doesnt even have that charging light. it only charges itself if its off and if there is no battery left, i have to put it on charge by draining the whole battery by using apps and stuff and i am so pissed right now i cant find a solution to this. Did you find a solution on how to get this fixed?
I am currently having a similar problem where I can only charge my phone if off. Hopefully someone can help!

I have found a solution to this. I am really happy since i am able to use my phone again.
Let me state what exactly i was going through.
I had to use the phone till it actually turned off completely consuming the whole battery and it was very frustrating because i had to deliberately use the phone till the phone shuts down and charge it. And once it started charging, it has a weird stupid way of charging. It shows that its charging and it goes off, comes back on and shows its charging, then it goes off... When it goes off the red light goes away...then comes back on.
I've read other threads and forums about people having the same issue. Others say they're not even able to connect their phones to the computer. You all should try connecting your phone to a computer and check if its able to transfer data.
If that happens, then you're saved. Because this really worked out for me.
Now, i'm not really sure what kind of bug this is, but here's how you fix this.
If you're able to transfer data to your phone, you must browse your phone on the computer and copy a file (or a couple of files - in my case i transferred a movie folder that had a couple files in it)
And guess what..i put it on charge and started charging like normal oh my god i was happy as hell
Thanks. I hope the same works for you all, people have been saying you have to clean the charging port but not really

I have the very same problem, my phone will only charge when the battery is completely drained, now i have like 25% and tried your way, my pc doesnt detect the phone :/
I tried with and withouth usb debug mode. :crying::crying::crying::crying:
Is this a sotware problem i guess? it wouldnt charge at all if it was hardware right?
Just checked and my phone now says "the usb host cable is plugged in, cant charge the device"

I'm not sure how are you NOT able to get it connected to your computer. Since i connected it to the computer, it didn't start charging but it allowed me to transfer files. And so i did. You might wanna change the cable and check if its letting you connect to your PC.
So far its working perfectly alright. I don't have a problem as such. And wait, you could install a file manager and move a couple files around. Maybe delete some files or download some files and try.
I Hope it works for everyone who's getting this problem. I know its not a hardware problem and HTC support sucks BIG time. i don't even have htc headquarters so i couldn't get it replaced, bad. but if your phone is under warranty you must get it replaced :laugh:

Hi! so you are saying that if i move some files from the computer to the phone it might get fixed? Well, i cant plug it to the computer, it just doesnt recognize the phone, if i plug it when the phone is on the pc doesnt show anything and the phone doesnt charge or anything, just like when trying to charge it with the ac charger, if i plug it with to the pc with the phone off then it shows a message that doesnt recognize the device, and the phone doesnt even charge aswell...
Right now the only fix i have found is to solve the problem of having to drain the battery in order to charge the phone, now i fixed it unticking the fastboot option in energy, now i can charge with any % but the phone must be off. Btw it gets a lot of heat while charging it this way... idk if its normal, i heard that because the aliminium case it gets more heat than normal plastic cases.
Thanks for your reply, ill try to connect the phone to the pc a few more times.
Hello guys , , I have the same problem , charging the M7 (On stock rom), I have tried many things ,roms and kernels , currently I managed to make it charge with the screen on with some conditions..
I installed SLIM ROM from their site (4.4.4) . To charge the phone with screen on I have to check "screen on while charging" (because if the screen goes off it stops charging /same thing if somebody is calling me )
To Charge my phone I just need to Reboot normally and charge it ( if you install this rom Activate the sound for the ac plug/unplug so you can know if it is charging well or not )
Eaven if i have to do these things its better then the OFF mode .
Hope It helps .
HTC M7 Only charges when it's off and the laptop can't recognize the device.
Hello, I've had this HTC M7 since last year. It's worked perfectly until a couple days ago.
The phone will not charge when it's on. It only charges when it's off. Also, my laptop won't recognize the device. I've tried with a couple different AC chargers, but no luck.
Sometimes my phone says "CAN'T CHARGE WHILE IN USB HOST MODE," and I don't know how to take it out of USB Host mode? I'm guessing this is a problem with the software. Before this happened the phone worked flawlessly.
Any help, please??!!

It can sometimes be caused by a defective usb port on the phone, does your port looks damaged? Boot your phone in safe mode and check if its doing the same thing.
I've already done that and it doesn't work.
I really don't know what the issue is? I mean this is a perfectly working unlocked HTC M7.
I've turned if off multiple times and even wiped it clean twice. I don't know what else it could be.
I mean it's been working perfectly since I got it.
But as I mentioned earlier it will only charge while the phone is off. And my laptop can't recognized it either.
It only appears and "Unknown Device."
But even when it is off it charges for a bit and then it completely stops.
Then you see the battery logo and then it starts charging again. But it repeat that same process throughout the whole time. So, it can never reach to 100%.
As I've mentioned before I've never really had this problem.
I've been looking for hours on the internet and so far nothing seems to work. There was an app I saw on to access engineer mode or something, but for some reason I can't use that app because it says that I'm missing another application.
Any thoughts??

I have the same problem, it can't charge, PC don't recognize when the phone is on android, but when i boot into recovery everything work fine (charge or data move to PC), so far i could't find any way better.
Hi,
had same problem.
Clearing system cache helped in my case.
Related cause for the trouble seem to be a couple of OTA upgrades I did recently.
(I was on a pretty old version.)
I noticed that there was something wrong while upgrading.
Even though the phone was connected to the charger while the whole upgrade process,
battery level went down...
The following procedure is your own risk!
Be careful not to choose any options that wipe all your data or factory reset your device.
This is how I cleared the system cache :
Boot into recovery (hold both volume-down and power buttons for ~30 seconds until menu shows - )
Press volume-down to choose RECOVERY and press power button.
Be patient ~60 seconds until menu appears.
Choose wipe cache partition and press power button.
Choose reboot system and press power button.
I hope this helps you.
Thanks

My phone had been working perfectly fine, as well as charging perfectly fine. Recently, I accidentally let it drop to 0%, which I don't usually do. I went to plug it into the same wall outlet as always, but instead of the usual charge process, the battery icon with the lightning bolt in the middle simply flashes on the screen and then turns off, which happens over and over again.
It should be noted as well that about 3 weeks ago my phone get fairly wet. After that incident, I turned it off till it dried, powered it up, and everything appeared to be totally ok.
Other facts:
-I can safely get into the recovery menu (power + vol down), which is stable, but any menu selections result in the Motorola splash screen for a quick second and then the phone powering down.
-The computer will recognize the connection to the phone.
Attempts to resolve:
-New cable, new usb hub, new wall outlet
-Trickle charge from the computer (same flashing)
-Phone in rice to remove moisture
-Toothbrush cleaning of Micro-usb port (suggestion from another thread)
I'm pulling my hair out, and I am considering prying off the back and replacing the battery. I have searched other threads, but have seen various solutions none of which worked for me. If anybody has any idea how I can fix this please help!!! Thanks in advance.

Either there is something wrong with your battery, or there is something wrong with the USB port. If the USB port is the problem, you can use wireless charging instead. I'm a fan of this one, personally: https://www.amazon.com/gp/product/B00S7IBDGW/ref=oh_aui_search_detailpage?ie=UTF8&psc=1.
Also, are you unlocked? If so, what battery percentage does TWRP say?

Thanks for the quick reply. It does seem like a battery problem, however it is just so coincidental that it stopped working after I let the battery drain to 0%, when only hours previously it was in use and charging without any issue at all.
Also, if there was a problem with the micro-usb port, I would think that a computer wouldnt be able to read the phone, but when I plug it in it is recognized as an ADB device.
I have another turbo with a cracked screen, I'm thinking about dissecting both and putting that battery in this phone as a replacement.
And unfortunately I am not unlocked :/.
Update
Well, after some further experimentation, I've gotten it working again. The solution was to charge it for like 5 hours, then let it sit off charge for an hour, and then it would boot... bizarre combination of actions. It has since dies twice and I've had to use this method.
It is working for now if I don't let the battery drop below like 15%. Seems more like a software or hardware issue to me, and i'm still trying to resolve it, so if anybody has any suggestions please let me know.
Also, what is the best way to re-calibrate the battery, maybe that could help?

If you can't let the battery go below a certain percentage, it might be an early sign of failure. The voltage might drop suddenly and unexpectedly towards the end of discharge, prompting the phone to emergency-shutdown.
As for calibrating the battery...it depends on who you ask. I would say that running it to shutdown (even if shutdown is "15%") and then charging it to 100% should do it, since that gives the controller a full set of data with which to extrapolate a discharge curve. Clear your cache in recovery, so hopefully the OS will pick up on this to accurately track the battery's actual state.
Get Kernel Adiutor or something similar to check your battery's health, too. If there's something obviously badly wrong, it should report something other than "Good".
If you note when your battery dies abruptly and you immediately reboot the back light is very poor. Almost flickering.
I think this is a battery issue of not being able to feed enough amperage.
...however. My phone was doing this and after a full clean reflash it has stopped. I question if this is because I am running less apps now. Or if perhaps somehow the battery managed to lose its memory. (Li ion is an odd duck..)

Thanks for the pointers. So strange, first it died at 40%, then 30% then 15%. Now, it is still dying early but I am no longer facing the issue I originally had, it will show normal charging when off, and boots up right away. Sure hope its not some ticking battery time bomb, its still a relatively new refurb.
I attempted the charge calibration so we shall see if it helps. I also did a factory reset for the hell of it, since I am on stock and can't reflash. Perhaps I'm in the clear, that would be awesome. Still no idea what the issue was in the first place though, which will annoy me to no end.
I found a SM-T813 for sale and it has the following error message: "An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software." The person selling it also states that whenever he plugs it into his computer it isn't recognized and reboots after 5 seconds.
This is what he states: Samsung Galaxy Tab S2 SM-T813 32GB, Wi-Fi, 9.7"
Needs Android Re-installed
PROBLEM: doesn't boot. When I connect it to my computer, I get the following message: "an error has occurred while updating the device software. Use the emergency recovery function in the smart switch pc software." And it keeps re-booting. Hopefully you can reinstall Android. Sold As-IS for repair!
I asked him the following questions and these are his responses:
Have attempted to reinstall Android?
- Yes, I've tried holding down the volume button to download mode, and I've tried connecting to my laptop, but it keeps rebooting.
What did you try when you connected it to your computer?
- Nothing, my laptop won't recognize it. The tablet will connect for five seconds then disconnect. The cycle repeats.
So you've tried the Smart Switch PC software that it mentions with no success? Does the tablet automatically reboot itself after being plugged into your computer after the 5 seconds you mentioned?
- Yes and yes
Does it seem like this is fixable? I've read quite a bit online, but it seems like it is one problem or the other, I haven't found anything with both problems. For the bootlooping it sounds like it may be a physical defect, in which case I'm not really interested in it, but I'm not sure if it is.
Can anyone help? It's for sale for about half the price of any other used S2 10" I could find.
Thanks!
Sounds like a bricked paperweight to me. But if you are intested in scavenging go for it, I'd say.
Simply appears to me like user error. If it's not charged it will reboot.
Also to boot download mode the right button combo has to be held regardless of whether it's boot looping or not. Seems to me he's not using the right button combo.
If you can get to download mode it's likely fixable.
Same problem...
I'm having the same problem with my tablet. So far as I know, there's really two different problems here:
1) There was the issue with the firmware, that could be taken care of with the Samsung Smart Switch, and
2) The device is out of battery, but because of issue number one, whenever the tablet has enough juice to do so, it turns the screen on at full brightness to tell that it is in such a condition, thus draining any battery that had just been charged into the device.
I still haven't figured out how to get it to charge, and that's really the main problem right now, is figuring out how to get it to charge either faster than the screen drains the battery, or without the screen turning on in the first place. The only solutions I could think of for that, is to open it up, and put a fully charged battery in (thus voiding the warranty, if there is one, but in your case probably not), or maybe (I haven't tried this yet, so I don't know if this would even work or not) opening up the tablet, and disconnecting the screen while the tablet charges, then reconnecting it in a few hours, after the tablet has stored up some juice. The second option would save the costs of buying a new battery, and its not even certain that the battery would have enough in it to go through the process either, but it is a lot more experimental, and I have no idea if it would even work without breaking the device.
Those are just two ideas I came up with, so if anyone else has a better idea of how to fix it without sending it to a shop, or opening it up, please tell. And just a warning, I've done some phone repair jobs in the past, but I don't work with repairing phones on a regular basis, so don't take me as an expert on this. If you choose to use one of the above methods, do it at your own risk, and make sure you study up on how to do it, or take it to a shop to have professionals do it.

Just boot it to DOWNLOAD mode or RECOVERY mode.
Also if your tablet cannot charge even at full brightness then there's either an issue with the battery or more likely the charger.
When the tablet is plugged into the mains the tablet should run indefinitely and charge at the same time if it's a 2amp charger.
(Please see post #4 as the issue has evolved)
I recently updated my husband's HD from CM 11 to CM 12.1 (the one build in @amaces obsolete folder). This restored some functionality to a few apps that had "moved on" beyond KitKat and preserved the HMDI functionality. Everything else is essentially the same. Except.
Too often on starting the tablet up in the morning it shows about the same battery level as at shutdown the prior evening (maybe 50-ish) and then in a matter of minutes nosedives to 1%. You can see the behavior on the power usage graphic in Settings and it's pretty shocking. There's a vertical line for when it booted up and then *bam*, it drops to essentially nothing. If the tablet is plugged in for just a moment, the battery level returns to normal and everything is fine. It can be disconnected from the power supply and behaves normally the rest of the day.
So this is annoying (moreso because I need to hear about it every time it happens ). I've read the entire (unofficial) CM 12 thread. This issue comes up once or twice and seems to be "resolved" by "calibrating" the battery either with an app from the PlayStore or without. The app seems to just delete a file that would be overwritten at boot anyway from what else I have read on the subject, but the main idea is to drain the battery to an actual 1%, shut down and charge (the tablet remains "off" although the screen is on) until you've got 100% (which has to be judged by the green LED since the tablet is off).
I tried this (with the app), beginning by wiping cache and dalvik cache. It seemed to work for awhile. Then I foolishly suggested doing a backup. I did this with the emmc TWRP and everything seemed to go well except the battery indicator issue started up again...
So we did the battery thing again.... And it was just fine until this morning (not what you want to hear as you sit down to breakfast).
Clearly one could live with this if you always have the charger close at hand, but it's pretty lame. The tablet behaves beautifully in all other respects. I don't think it's a hardware issue as it started right after flashing the new ROM.
One person in the CM 12 thread actually praised the ROM as eliminating this issue which he had from CM 11!
Is this a flashing glitch which might be fixed by reflashing the ROM? I'm loath to do a clean install and reconstruct everything again after such a short time, but I wonder if a "dirty" install (don't wipe data, right?) would be enough. If I reflash the ROM do I have to reflash GApps also?
Suggestions? I'm really at a loss here.

I doubt if a dirty flash would change anything, but there does not appear to be any penalty to try it out as a shot in the dark.

Not if you don't wipe /data -- basically same as in the case of a dirty upgrade.

I finally got around to this after much complaining about the issue and now I've managed to make it much worse. Before, the tablet would drop from the 50's (or lower) to 1% on boot. Higher percentages of charge were usually safe. Now it goes through the boot process up to the animation and then abruptly shuts down UNLESS the power cable is connected, regardless of the state of battery charge. If the cable is connected boot occurs normally and you can disconnect after boot is complete and everything is "fine".
Except, of course, it's not "fine" at all. Unless you have the charger and cable with you at all times, the tablet has to be left on when you're on the go.
Ugh. Any ideas besides going back to stock and starting over?

I finally got around to this after much complaining about the issue and now I've managed to make it much worse. Before, the tablet would drop from the 50's (or lower) to 1% on boot.

I came across a post that suggested returning all the way to stock and doing a factory reset, then rebuilding the system.
Once at stock I had no trouble completing a boot without being plugged in. So that is not a hardware issue. I didn't stay on stock long enough to see if the battery indicator behaved, but I'm guessing it did. I prepared a completely new SD card with newly downloaded files and proceeded to do the needed flashing for CM 12.1 w/GApps, using CWM 6.045. It all seemed to go well--even no screen flashing--until I unplugged the tablet so I could easily remove the SD card and reboot. As soon as I removed the power cord the periodic screen flashing that seems to be common during CWM use started up.
I rebooted and got only so far with the CM logo before the tablet shut down.
I don't get it. It worked fine before. What about this process could be causing this odd behavior?
Edit: in desperation I tried flashing The ROM again right over the prior installation. This time I booted into the emmc CWM (6.0.4.6) and waited for the tablet to calm down. Then I unplugged it and flashed the ROM from the ext.SD card. No error messages. I held my breath and rebooted. I got to several iterations of the cyan android face and then it shut down again.
Next I flashed TWRP 2.8.7.4 to emmc and tried flashing the ROM from the ext.SD card that way. Same result.
The battery charge shows 80% so it's not like the tablet is running on fumes and it's hard to believe the problem is the battery or the indicator since none of this happens on the stock ROM.
I just don't get it. We don't want to go back to stock but I don't understand any of what is going on. Initially CM 12.1 was working beautifully. Then the battery indicator issue started. I addressed that as best I could and when it seemed like we had that on the run I did a backup. That resulted in this shutdown issue. You can use the tablet just fine if you never turn it off and keep either the charger or a portable power pack handy (don't forget the cable!).
I really need some help troubleshooting. I'm willing to try just about anything.
Edit: indeed, the last resort was to buy another HD... But it turns out the booting issue was caused by an SD card that somehow was not properly prepared as 0x0C FAT32 LBA but was instead something else which I don't remember now (something with a "b"). Anyway, once a new card was carefully prepared, the tablet booted fine without being plugged in. Whether this also solves the battery indicator issue remains to be seen.
Hi all,
I have been using my phone (X520 on EUI 5.9.23S) for over a year without any issues and all of sudden the phone probably overheated(felt very warm yesterday and the battery was draining fast) and now it's not charging at all unless I enter TWRP and charge my phone that way but that is very, very slow and takes ages to charge.
When I try to charge my phone the normal way, the battery indicator even turns green for a split second but then quickly changes back to white and refuses to charge as if a safety mechanism is in place that is preventing the phone from charging. Also, when I connect my phone to my computer, USB modes are not coming on the phone anymore nor is the computer detecting the phone properly. (I get "USB device is unrecognized" error message)
The TWRP method is so slow and inconvenient so I would appreciate if someone can help me out here.
By the way, I am on IllusionKernel but have tried OverloadKernel as well but the same result.
Thanks in advance.

Try replacing the stock boot by using “fastboot boot boot.img” which should restore stock kernel, may be EUI isn't supporting the custom kernels well.
However I am unsure,I read about this on a form some months ago so can't guarantee this will fix it or worsen it.

Thank you for your response. I have been using a custom kernel(s) for months and this just happened out of nowhere. I will still try to revert to the stock kernel.
Might be due to battery damage , probably needs new battery.

This could well be the case but it charges very slowly through TWRP and when using the phone, everything seems normal (no overheating or battery drain) so I think, it's something else that is the issue. Also, my CDMA official headphones are not working either during the call or even when watching videos.
