It is a bit difficult to understand what are you saying.
It seems like the battery does not hold charge and while it starts booting it goes off because your charger and cable isn't powerful enough to keep the phone running. Do you have another charging cable? And maybe another charger?
It's the crappy quality battery Samsung put in the S4.
Mine starts doing that at 30% charge.
And you have let it charge for a bit using the 2A charger before starting it up.

My elephone s7 run out of battery this morning so my first reaction was to plug it to the charger and power it on after 5 minutes.
When i plugged it in it did not show me that it was charging and also it didn't power on..... i have pressed the power on button but it does nothing ...
Need some help i have run out of ideas...
i have got a same problem too... my phone still 20% and i charged it, and suddenly cant power on.... anyone help?
i already tried Volume Up + Power Button, but still cant... please help... thanks
I have Galaxy S8, my problem is I flashed a custom ROM, and it's bricked (stuck at boot logo). I still charged my phone, and suddenly it turned off, I realized that since then my phone aren't charged. A black power logo (charging screen?) now comes up but the LED indicator for charging is not turned on while I connect my phone to charger. What I have tried:
1. Using original cable and charger. Using another cable and charger does not work too!
2. Connect it to my laptop. Does not work.
3. Use different electric socket (2-3 sockets). Still no luck.
4. Power. Not work.
5. Power + Vol Down. The device is turned off, but then the charging screen comes up again, still, I cannot power on my device.
6. Power + Vol Up + Bixby. Not work.
Is there any suggestion what should I do now? Please don't tell me it's a hardbrick. :crying::crying::crying:
Hi; try to change your charger. For me it's that the problem.
Could be that it's deeply discharged. Had that problem with my HTC one m7. I let it charge for a day and that did the job pretty well. After that, I could charge normal again.
I would try HOLDING the Volume Down + Power for at least 7 seconds.
Supposedly, this simulates pulling the battery, and gives you a few options, including rebooting or factory resetting. If you're thinking you're bricked, a factory reset might be best. Good luck.

Hi There,
I need help with my S8, the phone won't turn on when pressing the power button even though i left it on charge all night even tried to boot it in recovery mode and ODIN MODE and nothing it won't turn on, the only way the phone comes on and that's when i plug a USB cable into it and it only loads up (SAMSUNG GALAXY S8 screen) and the only way to turn it off is to press POWER BUTTON, BIXBY BUTTON and VOLUME DOWN BUTTON to go into ODIN MODE, but that's when the next problem occurs it doesn't go into ODIN Mode just basically turns the phone off and also while the phone is on the same screen (SAMSUNG GALAXY S8 screen) i tried to quickly press VOLUME UP, BIXBY BUTTON and POWER BUTTON all at once and it does nothing just stays on the (SAMSUNG GALAXY S8 screen) even pressing the POWER BUTTON alone does nothing, but like i said previously it can only be turned off when on (SAMSUNG GALAXY S8 screen) when pressing POWER BUTTON, BIXBY BUTTON and VOLUME DOWN BUTTON.
So Basically,
ODIN Mode Doesn't Work
Recovery Mode Doesn't Work
The only way the phone comes on is through USB Connection
Is this a battery problem or firmware problem or something else

Thanks for the reply,
I'm going to take your advice and get a new battery installed hopefully this solves i, thanks
I have finally solved my own problem it was just the firmware
So here's what i did
As i plugged in the usb cable for the phone to come on i quickly pressed VOLUME DOWN, BIXBY BUTTON and POWER BUTTON to boot into odin mode and it actually booted into odin mode and i reflashed 8.0 firmware and now my phone is up and running.
So if anyone else as the same problem then try what i did above.

Could you help guide me through the flashing process? I have a similar issue as you but haven't had luck trying to flash it so far.

Must try usb jig
Hello,
a friend of mine dropped his phone into water. However, I dried the phone as good as possible without opening it. Now when I start the phone it gets stucked at the Samsung Galaxy A40 secured by knox display. I let it for hours but nothing happens. When I restart the phone by holding volume down + power and after that I press power + volume up I can enter the recovery mode. Before I make any mistake I wanted to ask if I can get acces to the internal storage of the phone to get back the pictures and videos. May it help to wipe the cache? Or can I install any apk to get the phone connected to the computer?
Kind regards

How to use your broken smartphone from a PC | nextpit
Has your phone screen cracked, leaving you unable to access your data? All is not lost! We'll show you various solutions on how to recover your data!
www.nextpit.com
This site shows the option to connect A40, if still Android 9.0, via usb hub to external screen and mouse and unlock. For Android >10 this doesn't work anymore
I have the same issue and neither usb-debugging on nor fastboot enabled. A40 doesn't show up in adb. So I also read when putting A40 via Power and Volume up into download/recovery mode, at least a backup of data should work.
My current idea is I have to replace display in repair shop or unlock via usb-hub + mouse.
Something I don't get right. How do you power off the A40 without screen to get safely the SIM card out? Power and volume down 7 sec, then release power off, then volume down? When I do this the A40 reboots with vibration. Power and volume up apparently reboots to recovery mode. Long pressing Power also doesn't turn off A40. Also in the A40 manual nothing is written on this
I'm having a similar, but worse problem: a friend of mine let her A40 fall into the toilet at a party. When she came back home, the phone wasn't working anymore and the battery was swoolen. We've tried to dry the phone with the good old bag of rice for a week, then I dissassembled it to take out the battery and see if there was any damage inside.
While there is no visible damage, the phone doesn't give any sign of life, not even with the usb cable plugged in.
So I have two questions: is the A40 supposed to boot without a battery plugged in, just using the USB cable as a power source? In the worst case, is there a way to recover the data from the phone if it's not possible to boot it (I bet the answer to the last question is no)?
