By the coincidence, is your batt serial no beginning with BD? If so, look on the battery. Is it swollen a bit? If so - call samsung, they will replace battery free of charge.
If not, try to connect phone to charger, insert battery, go to recovery and make full wipe.

it might be a power button issue

ok, this may be tricky.
while keeping volume down and home - slice battery in. If phone would boot in download mode (even just for a while) - then it will be power button issue.

it boots up on download mode for seconds and then powered off again....

Im digging up this post because this is the same problem i had.
I ended up removing the power button all together, carefully popped it off the motherboard. The phone no longer boots for a couple secs and powers off again so i think the power button was the issue. Now i have the problem of powering on the phone. I tried booting into download mode (to have the reboot option) by holding volume down+home while plugging it in but nothing happens, all i get is the battery charging icon. Ive been into download mode before i removed the button, but like the OP, it would only be a second or 2 before rebooting. Am i doing the correct procedure for download mode? Perhaps my timing is off? Any suggestions?
At least i do get the battery charge and it stays until i unplug the phone, no more boot loop!

Ok so i managed to get the phone to power up without going into download mode using this method i found on youtube. No boot loop and fully powered up now, the only thing is that im stuck on the lock screen. My friend cant remember his pin so i cant get in, the only option left now is to boot into recovery and do a factory reset yes? Well, how can i do that without a power button? Any suggestions?

[Q] Sprint Galaxy S5 Not Powering On

Can someone please give me some advice on what to do. My phone is less than 3 months old and will not power on. It doesn't do anything, not even the vibration it usually does. I've tried plugging it into the charger but it doesn't even have the charging light on. It was working fine and just stopped. I pulled the battery out and put it back in but nothing it working. If If anyone has any suggestions, I would be very grateful! Thanks!!!

what were you doing at the time
What were you doing at the time the phone stopped working? Did you try charging the battery on an external charger?

As the poster above suggested, what were you doing recently? We are looking for clues as to what happened? Did you yank on the power cord, drop the phone, et cetera?
Make sure that your battery isn't in backwards in the phone and try using a different cable to charge the phone. If it still doesn't charge, then borrow a friends external charger.. or even the (charged) battery out of their S5 for a few seconds to see if your phone will turn on. We're trying to differentiate between a dead battery and all other problems.
If you still have no luck, then remove the battery for ten seconds, then replace (the presumably charged) battery in your phone. Then press and hold the volume down key. Then also press and hold the home key, then the power key. After about five seconds, you should see the phone start to the "download screen". If so, post here for further guidance.
If you phone is non responsive to a borrowed battery and the download mode described above, then you should seek warranty service with your carrier. A three month old phone should still be under warranty.

I was talking on it and hung up. Then, I tried to use it about 5 mins later and it wouldnt turn back on. What do you mean by "external charger"?? Sry, I'm not very tech savy lol! The only charger I have is the one that came with my phone. Thank you for replying! ☺

My battery was charged in the 70% and I also used my husbands battery (we have the same phone) but that didnt work either. I'm going to try your other suggestion. Thanks!

Can you get into recovery ( volume up + menu +power button) or download mode (volume down + menu + power button)?
You may read this article http://www.technobezz.com/samsung-galaxy-s5-not-charging/, hope it helps.

I tried the volume down + home + power and it didn't work. I'm not sure what to do. I don't want to make a trip to the store but it's looking like I'm going to have to.

It may well be an electrical hardware issue, it doesn`t look like a software problem to me. Good luck and i hope its fixed soon

It is looking like a hardware issue. If you are positive that the battery is charged.. i.e. if the battery turns your husband's phone on, then we ask what is different about your phone? Most software issues would be bypassed by starting a phone in download mode, which is why I asked you to try that.
Have a quick look at the battery "fingers" or pins on your phone. Those are the gold or silver coloured pins that line up with the gold or silver tabs on the end of your battery. Do they all appear to be the same? There isn't one that is bent out of alignment or shorter than the others where it might not be making contact with the battery?
And why not try one more test? See if the phone will start up in "recovery mode" this time.
Pull the battery out of the phone for ten seconds. Then replace it. Now in order.. press and hold the volume up button, then press and hold the home button as well. And last, press and hold the power button. Continue holding all three for ten seconds or until you see the phone screen turn on.
If that still doesn't work, my best guess is that you may have accidentally banged and damaged the power button. If it was me.. I'd try pressing really hard and wiggling the power button for a few seconds to see if you can cajole the phone to power on at least once and confirm the problem.
But that is about all that we can do. If you can't get the phone to power up with a known good battery.. then th store needs to check it with test equipment to narrow down what the hardware fault is.

Phone not turning on and led flashing rapidly

I just flashed MOAR rom on my phone a few days ago and everything was working perfectly then while at work I pulled my phone out of my pocket and noticed my case had slipped off and was holding the power button down. After fixing the case I tried to unlock my phone and nothing came up on my screen. I held down the power button and the only thing that happened was my LED indicator is flashing green rapidly and at different brightness. Then I pulled the battery and left it out of my phone for 2 hours and still the only thing that is happening is the LED. When I plug it into my computer without me hitting the button the LED is flashing. It wont boot into recovery and I don't want to send it in and them find a custom rom on it so any help would be greatly appreciated.

I am assuming it won't go into download mode either? Try holding the power button in for at least 30-40 seconds.

No, I've tried holding just the power button for a minute or trying to go into either download or recovery mode and got nothing.

Try the same thing with the charger plugged in.
"Try holding down the power button for 1 minute with the charger connected. If this doesn't present the screen, try holding the power button AND both volume buttons at the same time. This should bring up a menu. There should be an option for reboot or force reboot"

Thanks for trying to help, I've tried holding both volume and power button for a minute and nothing. After having it plugged in for a few minutes my battery started to get warm.

Just something I found while looking for answers. At least your battery is getting warm. That is better than the alternative.

Are you using the original data cable? Try a different USB port maybe?

phone won't boot/start up

I have a at&t S4 that all of a sudden today stopped working. When I restart the phone by taking the battery out and putting back in, it gets stuck on the Samsung Galaxy S4 logo and then a black screen. I tried going to recovery mode(volume up + home + power button), and it shows recovery booting in blue for a sec then goes black. I tried for download mode the warning comes up but after pressing volume up it goes black. I really don't know what to do at this point.

Tried using kies or smart switch to perform a firmware recovery?

Yes, the computer doesn't recognize that the phone is connected. It's as if when the phone goes to the black screen its actually powered off. The only time I get anything from the phone is when I pull the battery and reinsert it.

When the phone battery are too low, the phone could behave like that too.
Do you know that battery is fully charged or has more than 60%?
If not charge the phone first.
Plug the charger. If you did not see any sign showing that you phone is charging, press and hold the power button for 10 sec and release it. You should see the phone charging image.
Let me know whether your phone has enough battery power left but showing the above mentioned problems.

Yes, the battery is fully charged. I have another S4 Active that I've swapped the batteries with, along with a spare official Samsung battery and charger. It doesn't matter which battery I use, the phone acts the same with any of the 3.

If you have enough battery power left but the phone was behaved like that, you might need to flash the firmware.
Are you in lollipop or kitkat? For the time being, the only firmware available for kit-kat and lollipop is NB1 firmware cooked by muniz_ri . You can get it from here.
You mentioned that you can go to download mode but the phone shut off when you press volume up to go to the download mode after the warning.
Try the 10 sec method. Go to the download mode (power+home+volume-down) but keep holding the power button for 10 sec even though you see the warning message appear. Then you press volume up to go the download mode. Try this way and let me know.

It was on Kitkat. I can press the volume up and get it to show the download android screen but it immediately shuts off. Holding the power button for 10 secs. and then the volume up didn't do anything. The phone shuts off after 1-2 secs. of doing anything.

That is strange. The same thing happened to me. But I avoided the phone shut down by 10 sec methods.
Just hold the power+home+volume down for 10 sec, even though the warning sign show up, and then let it go all of them. Plug the phone to the computer and then press the volume-down to go into download mode. It works for me. Not on the first try though.
Try doing that with batter charger plug in too.

Thanks for your help. I figured out whats wrong, its got a faulty power button. I took the phone apart, put it back together, and was able to get it to boot completely. The slightest touch of the power button causes it to reboot though, so I'm going to need to replace it.

Glad you found the problem. I was trouble shooting for the software error.
Yes, power bottom could give you a problem too. I use screen off app so I do not have to use power button to turn off the screen.

PH-1 requires long press PWR button to boot - Any ideas why?

Hello,
I just purchased a used PH-1 and it was reset before I got it. So I put in my Google credentials and restored a backup no problem. The first few times I powered the phone down and plugged in a charger, I saw the battery charging graphic icon (looks like a coffee to go cup : ), no problem. But now, when I power down the phone, the screen is black and stays black with no sound or vibration when I plug in the charger. It still *does* charge in this state, but when I try and boot the phone back up, I have to press the Power button for 10+ seconds and let go before it will boot. I suppose I can continue to use the phone this way, but I was wondering if there was a reason and/or fix for this that anyone is aware of? thanks so much.

Sorry I should have mentioned, I tried several cables and chargers... same result.

Another issue I noticed. If I turn on the phone when it's plugged in, it goes to the bootloader (which is locked). I have to unplug the phone if I want to boot to the OS.

Make sure you're not fat-fingering the volume down button and the power button, because that combination is guaranteed to get you into the bootloader.
