let the battery drain all the way to the 0%. ive had same issue few times with my s7 edge it would not respond to any command no matter what i do, then all of the sudded after i didint touch the phone for abouth 6-7 hours i put it on charge again and 0% was shown and started charging.
most probably its a motherboard issue and should be replaced at least in my case

Thanks for your response, i've left it unplogged for more than a day and still nothing. Should i wait longer?
How expensive would replacing the motherboard be?

I'm only telling from my experience, untill your battery is 0 it will be like that presuming it has somewhat same issue as mine . Try pressing buttons from time to time it could help to drain battery faster . On second hand market it should not be more then 40-50 euro. Also AliExpress has motherboards but not new, used

R.I.P S7 edge 2016-2019 will be missed

Same thing ! Phone just totally dead.
The same thing just happened to my S7edge today... I think it's a conspiracy so that we are forced to change the phone.
Sad, I liked that phone.
Nothing would work, it started at first a rebooting loop, then suddenly stopped giving any sense of life.
Doesn't show any indication when plugging the charger. nor responsive to any of the rebooting button combinations...
I even had it on stock Rom and never flashed any customer ROM on it or anything.
I think leaving the phone battery to drain as a solution only works if your phone was already on and it just gave a black screen, but it's still on.
But in my case, it was already in a rebooting loop and I suspect it is not even ON anymore, it just went totally off somehow...
So there is no was to know if the battery is draining.

update:
So I left it overnight. In the morning, I connected the charger and indeed it drained to 0% and started being responsive to charging again.
As soon as it charged to 20% I powered it on. It loaded into recovery, giving the no command screen. Then I went on and selected system reboot.
Then it rebooted and Android started, as soon as I tried unlocking it, it froze and started again into an endless rebooting loop until it blacked out again. Now again not responsive.
I will leave it to drain again. Does anyone know what I shall do when it gets to that endless rebooting sequence. It is obvious that Android had a malfunction... not sure what as I didn't do anything new last week..
Is there a way to get it through without factory reset?
Thanks

seemingly dead Hermes.. help :(

Hey all, I've searched the forum and not found much at all..
I have no idea why this happened but my Hermes won't turn on at all, power button has no effect whatsoever and when I try to charge it I get the red light of death..
I put it down on my desk with ~80% battery last night and when I went to check for messages (by watching the service LED for a few seconds) in the morning the LED wasn't flashing so I tried waking it up and it was dead.
Plugged it into the charger, RLoD.. what the ****?
Anyone have any idea what could have gone wrong?
Usually caused by something that causes the battery to drain below 10%. Then you can get the RLOD. The charging circuit gets locked up and won't allow the device to charge. A pesky problem, but at least you have the RLOD, if you didn't then it could be the motherboard fuse.
So some things to try, non of them guaranteed and sometimes it works after trying these things several times over:

I have put my battery in my friend's Hermes and it says its 100% charged, I have put his battery in my Hermes and it still won't boot..
It's really weird.. BTW already tried your RLoD fixes, none worked.
I really hope I can fix it, I keep trying to slide open the non-existent qwerty keyboard on my Magician and it's frustrating using an OSK :S

Other than hard reset (don't think you mentioned doing that) I have only one other suggestion and that is the battery contacts. Hopefully not fractured between the pins and motherboard, but worth a try at cleaning the contacts and pushing the battery against the contacts.
If that doesn't work then I fear a motherboard fault.
Mike
Ok well for some reason my Hermes decided to boot up this morning after sitting on my desk for a night..
Weird stuff..

It is strange. Sometimes charges can build up within capacitors in a circuit and the "logic" can be disrupted. This is why sometimes it's a good idea with some faults to leave the battery out for a while to clear any such charges. However in your case with all the battery swapping and so on, I am a little sceptical that this was the cause.
If it happens again, I'd certainly be looking for a fault between battery connectors and the battery or between the connectors and the motherboard.
Let's hope that's it cured however

Well make sure the replacement battery has full charge....and retry ...also insert your battery into another phone and check if its chaging....because usually the phone starts up unless the battery has gone bad....if the phone doesn't switch on...I guess its a hardware issue...which I highly doubt....make sure the wall socket is functional as well....these are little things that could be triggering this...so check everything. ..good luck

They said that my motherboard is broken and the warranty just cover their service. So I guess have to pay for the motherboard. Do you know how much is the motherboard if an s4?

Same problem I'm facing right now but luckily my phone is under warranty

Nexus 4 won’t boot up/work without charger plugged in

My phone is shutting down automatically after showing “google” logo. I went back to stock lollipop 5.0.1 but the problem still persist. It’s working fine with the charger plugged in. If I remove the charger after switching on, if I kept it idle, it will stay on till the battery is empty. But if I try to do something it will shutdown. In recovery mode it works well without the charger.
Please help me is anyone facing the same issue.
may be you should try flashing a new kernel
i tried stock Google images still no use.
Is there any noticeable bulge to the battery? It might be a battery issue.
This is almost certainly a battery issue.

I don't think its a battery issue, because if i keep my device idle it'll last 1 day.
It only crashes if i use the phone, even swiping home screens crashes the phone.
Well, you've already gone back to pure stock which rules out a software issue, and so the next thing I thought would be a battery issue. I have read here about defective batteries causing all sorts of problems like losing signal, non responsive touchscreens and bootloops, and so it's a possibility that this is a battery problem.
I got strange problem with my n4..
Battery % randomly change and shut down, unsensible touchscreen, battery icon disappear from menu..
Maybe this hw problem could touch the SW part
that's how my problem started
Battery problem symptoms can manifest themselves in many different ways.

battery arrived everything is good
I have a same problem
My nexus 4 cant't turn on without charger plugged in. But when I go to Recovery, it work fine. A few days ago, it's sometime shutdown suddently when I was playing game. Then it worked fine after I plugged charger in and turn it on. Is this battery issue?
So even when the device is fully charged it won't boot into Android?

It can boot with a little trick (press the lock icon on boot screen continuously) and work fine with charger plugged in. When unplugged the phone shutdown immediately

Phone doesn't turn on

Hi all,
I'm having a bizarre problem with my OPT. The thread title doesn't really adequately explain the issue. Basically, if I shut the phone down, it will not turn back on. It won't boot to fastboot, recovery, or system. There is simply no response. If I plug the phone in, then after hours (or minutes, randomly), the battery icon will pop up with a red charging light (indicating a low battery?). However, it does this even if I shut it down with a full charge.
As an example, I shut it down before i went to bed last night (with ~80% charge), and left it plugged in. I got up this morning to no sign of life, not even a charging light. I unplugged it, plugged it into my PC, and an hour later I hear the little "new device" sound, and suddenly the red charge light is on. I wait some time, then attempt to turn on the phone. Then I hear the "device disconnected" sound, and it's dead as a brick again.
It also does this once the battery gets full. Eventually after attempting to power on the phone over and over again, it will randomly decide to turn back on, and then the phone works fine until shut down/rebooted.
Has anyone experienced this or have any advice? I'm hoping I just have something corrupted in my boot files or something software/firmware-related, but it makes the phone essentially unusable (and I certainly can't install a different ROM or anything while it's behaving like this).
Hi
Flashed Bad file ? Power problem ? Dead battery ? Charger problem and / or cable ?
But I already had that on my OnePlus 1 and I just changed the battery ... If it helps . Good luck anyway !
Be tested no choice. Unless you have the guarantee and a lot of time to waste in OnePlus...

I haven't flashed anything recently. I got the phone in September... unlocked, rooted, flashed TWRP, but haven't done anything since.
It's acting like the battery is completely dead, and it needs some time to charge before it will allow me to turn it on. But the battery is almost full.

You often dumps your O+ thoroughly ?
Because if so, it's not a laptop battery after I could be wrong but from my misadventure with OnePlus 1, it tires more battery than anything else. (On phone) :silly:
That way I'm not saying Fakir but I think if you have the guarantee, you should try to open a ticket to return your Oneplus. :good:
When my OnePlus fully discharged for a while he puts around 10 minutes to re-ignite (Oneplus 1) it is also how I ****ed my first battery on the OnePlus 1. :crying:
Not try to completely unload the O+2 from...
I'm just trying to help. :angel:
( PS : I still want to clarify that OnePlus 1 when it makes a point that the battery is empty it puts at least 10 minutes to light if I have the logo of the empty battery in red, even super you tell you my phone is dead ! And It is not ! If you know how is the process of loading a battery. And if such is your discharge too fast or you have a problem or charging your battery discharges of a sudden, I tell you it's more than problable so that your battery is lame. ) ( Sorry 4 my bad english.... )
The battery wasn't dead, I just shut the phone down. I very rarely discharge it all the way. Battery life is fine when the phone works. It's almost like the charging circuit THINKS the battery is dead and won't let it turn on. I'm not sure if this is a hardware or software issue.
Actually I just turned the phone back on. I just kept pressing and holding power until it finally responded and turned on. But now I'm afraid to reboot it again, or i'll be without a phone for 6+ hours.

Did you try to do a full wipe and install stock OxygenOS 2.1.2 ? ( Without SU or XPOSED ?)
Good luck anyway ! For me it is 0:23 am in France and I'm k.o :silly:

S7 Edge isn't turning on

Hello.
So, I recently updated my phone 2 days ago for the first time after 2017, and the battery ran out while it was updating, and then it was boot looping and kept getting stuck at 28%.
I decided to reinstall the os on it (I installed the official rom that the phone came with). At first, everything seemed normal until I plugged it and after a while, the led indicator was showing that it was still charging but after I unplugged it from the charger, the light was still on and the screen was completely black and unresponsive.
After a while, the light shut off and after that, it never came on. I tried everything to get it on again: tried hard rebooting, trying to get into recovery, charging with different types of cables and with wireless charging also, basically every combination that came to mind. When I used the wireless charger, it showed that it was charging, but no signs of life on the phone. Samsung support wasn't that much of a help either, they only asked if I used a cable that worked on it and if the phone was water damaged or had any cracks.
Any help will be appreciated!!!

How did you reinstall the OS?

by putting the phone into download mode
Connect usb (not charger) hold vol- + home + power, release power after 5 sec n continue holding vol- + home . If download mode appears flash phone with same csc firmware. If no downlooad mode probably battery or emmc fault.
