Anybody else experienced this? Same issue persist on stock rom, so I think my battery is shot.. Any tuips or suggestions are appreciated. Battery never charges past 73%, used to be 83%. And constant drop of power.
Have you tried to charge it in Power Off mode (hold power button down for 5 seconds and then choose Power Off) wait a few seconds for it to shut down, then try to charge it - you should see a battery icon, see if it will reach 100% in that state (can press the home button or power button to check status it should show 100% when charged)..
If not make sure you are using the official Samsung Charger and Cable - there are a lot of Chinese knockoffs so try to use originals.
(The reason I ask to try in power-off mode is because it eliminates abusive apps , CPU, Screen On , WIFI, BT, GPS and other settings from sucking power, Power Off mode ensures all the power goes directly to the battery)

<Quote>My epic 4g won't power on. If I plug in a usb cable/ac adapter it will charge the device. The screen comes on and shows the green battery and the amber LED turns on and then turns blue when it reaches 100% charge.
But the power button does nothing. It won't power it on. Is there anything else I can do to force it to turn on?</Quote>
So I got it to boot up. You can do this by holding the power button down while continuously unplugging and replugging in a power adapter (or usb cable). You may spend 2 or 3 minutes unplugging and replugging it in (you need to do this rapidly) but eventually you'll be greeted with the samsung boot screen. If it makes it to the battery display screen you're not unplugging and replugging in quickly enough.
Hopefully o that anyone else who encounters this problem can potentially use their phone in a pinch or recover data off one with a broken power button. My power button is definitely busted and I'll need to get it repaired by sprint unfortunately.
Thanks!

Did you try putting it into download mode? may need to ODIN back to stock.
Ok im new to this forum, as i just ditched my evo shift and picked up and epic, but you might try booting to another menu. Try unplugging it and holding the 1 key on the keyboard then press the power key. If that does nothing then id have to guess ur actual power button is broken. You could also try pulling the battery witih it unplugged for like 5 minutes then put it back in and hold the power button for like 20 seconds and letting it go.
Edit: He beat me to it
It appears the actual power button is broken, neither of those solutions worked. Is there any other way to force it to power up without use of the power button?

Thank you soo much! I have a messed up Epic that has to be sent back to Sprint but I had to get my work information off of it or I'd be in it deep. Your trick worked perfectly!!
Hi. So after a long wait I got my Zenfone 2 ZE551ML today. The first thing I did was turning it on and it turned on normally, then I proceeded to make the initial setup (logging into google account, etc) without any problems. Then after about 10 minutes of use the phone suddenly turned off with the battery being at around 35% and didn't want to turn on again. I read that old firmware (like the one that comes default with the phone) had battery display errors so I thought the phone had run out of battery, so I charged it for 8 full hours and I unplugged it now. To my surprise the phone is not turning on either. The only way I can make the screen show something is by connecting it to the charger, it vibrates and displays a white battery icon, eventually changing to fully green (fully charged battery, the green led indicator also appears) only to disappear like 3 seconds after. Can't turn the phone on while charged and can't even make the phone show the battery icon again (unless I unplug and plug again, repeating the cycle). So, what can I do to turn it on?
Thanks in advance.

I have a feeling that you did not hold the power button long enough. Disconnect the charger first, and wait for about 10 seconds. Then, hold the power button for at least 6 seconds. The phone should then vibrate and then you may release the power button. Other reasons why your phone may not seem to be turning on at all might be due to the back cover not being fully locked in, thus not making any contact with the power on the motherboard itself.
Do report back the results.

I did. Doesn't work. I also removed the back cover and pressed the power button with nails with no results either. Personally I think there's something to do with the power button as it doesn't even responds while charging (pressing it should display the battery icon) and the only time I could use the phone it didn't work to wake up the phone or setting it to sleep, only double tapping worked. What is strange is that it worked the first time I turned on the phone though.
Are you able to get into FastBoot mode? If so please try performing a hardware reset including wipe cache partition. Please see the following:

I got that several times when connecting my phone to the PC. I removed the back plate and disconnected the battery, after reconnecting phone booted up.

hi guys,
sorry if i had to ask this i think i'm out of options that i'm aware of.
i have a tab s t705 which has been on stock firmware for the longest time(5.02, country PH) and a week ago it just died.
the tablet charges but does not turn on. i can get to odin and recovery modes but it does not boot to system. also it does not turn on when i unplug the charger.
what i've done so far:
. pressed the power button for more than 30seconds, unplugged - nothing
. pressed the power, home, and -vol buttons for about the same time, unplugged - nothing
. pressed the power button for the same amount of time, plugged - only charging icon with batt level, nothing else
. pressed the power, home, nd -vol buttons for a few seconds while plugged, gets into pdin mode but restarting it just goes back to charging icon
. pressed power, home, and +vol for a few seconds while plugged, gets into recovery mode and after trying factory wipe and wipe cache, still goes back to charging icon when rebooted
. followed a guide to remove the back cover and disconnected battery for more than five minutes and did the same steps - same results
. tried plugging in to computer where it was installed before - not detected, not even odin(3.05 - 3.11 versions) does not detect it
this tablet is absolutely out of warranty already and i sort of like this tablet. any chance i can still revive this, or were there some steps that i have missed?
seriously, thanks in advance for any help
If you have an DMM check the voltage of the battery it should be 4.35v fully charged battery, If the battery is faulty maybe that is what is stopping the tablet fully booting, maybe somebody else knows.
John.
unfortunately i dot have acces to such tool but i really am hoping that this could be just a dead battery.
i'll see if replacing the batt would fix this and reply back for the results. thanks!
I was using the phone and hit the power button for sleep. Then when I checked it 1 hour later it will not power up. It there a way to reset the phone, this is why I hate phone you can't take the battery out of. But it is just a travel phone and now I am stuck.
Any key combinations or anything! ??!?!
You should be able to just hold the power button until the screen lights up. If that doesn't work hold the power button while connecting the usb c cable to charge it
Power button+volume down for 30 seconds.
Most likely the qdloader 9008 bug.. Volume down and power for 60 seconds always fixes the issue. Either that or let it discharge on its own for a day or so then plug it in and you're good to go!
Hi !
Have anyone sorted this problem with suggestion ?
Mine is getting warm when charging (warmer next to the power button area) but still no led indicator or power ON !??!
When I have my phone plugged-in and press the power button to turn the screen on, there is a significant lag, versus un-plugged.
Anybody know why? My guess is everything is reduced to save power.
