Got my new Elephone S7 today. Had some charge from factory but went fast. Tried the obvious stuff. Cleaned port, diff charger,
diff outlet. No luck. Can't reboot cause no power. Any ideas? Thanks
Hi, did u tried to charge the set while it is powered off. Mine was not charging after I did a factory reset, but after powering it off I tried to charge and it did
Hi, had the same problem when i received my s7
try to gently press on the little plastic connector inside the charging port with a little blade or something thin, it worked for me
change usb cable work for me. used high quality usb cable

I recently flashed my Defy with 3.4.2-179-2 CEE DEBLUR and it reboots every time I plug in my usb cable. It doesn't matter if it's connected to a PC or to the power adapter. Anyone have the same issue and know of a solution?
I did a google search and found someone complaining of the same issue but didn't see a solution.
More background:
I had an issue with my phone and when I went to do a factory reset I was stuck on the google screen. My power ended up running low to the point where I couldn't run the bootloader. I had to charge the battery manually with a battery charger and some wires. I monitored the voltage throughout to make sure the battery was ok. After flashing the new SBF I found that things worked fine except whenever I plugged in a USB cable it would reset. I put CM7 on the phone hoping it'd help but the problem still lingers.
I will probably attempt to flash another SBF or maybe reflash the existing one.
Does this problem only exists if the phone is fully booted or does it happen if you plug it in while booting also? Because if its happening while booting too maybe your usb cable is broken and theres a short in the cable that makes the defy reboot. Have you tried another cable? And what about plugging the cable in before booting the phone? Tried this already?
I encountered this problem occasionally before. Dunno why.
There's 3 possible issues here apart from software/firmware causes.
1) The USB cable might shorted.
- This can be confirmed by using multimeter to test the usb cable. You will see a shorting between to wire in the USB cable.
2) The Phone USB port might shorted.
- This can be confirmed by using another good/new usb cable and test it with multimeter.
3) Phone battery broken(happened when you charge it using wire and external charger).
- This can be confirmed by trying another Defy battery and charge it.
hi farsight,
upon further inspection i'm pretty sure the usb port is shorted because if i squeeze the bottom of the case the phone will reboot.
is there any way i could fix this? I've looked at some videos for the disassembly of the defy.
hi iregistry,
yes the issue occurs if the phone is fully booted and when it's booting.
quit risky la.. if under warranty, why not claim/RMA?
hi adie, i bought it new on ebay and i'm not sure how the warranty works on that.
[solved!]
after further testing I believe it was because the battery contacts were not as close together as they were originally due to me manually charging the battery. It must have been right on the very edge because it would work normally but just squeezing it would make it lose connection.
I used a pin to push the contacts closer together and hope this solves the issue. I've plugged in the usb and squeezed the case and so far everything seems ok.
IMO this is a poor design on motorola's part. the raised contacts on the phone are nice but the contacts on the battery are poor.
Thank you everyone for responding.
Had the same issue. Your solution worked on mine as well. Pushed the contacts on + and - in, and it worked! Thank you!
I had the similar issue. I had attempted to charge battery with external universal charger and looks like since then this issue where "phone would reboot upon unplugging the power source" started. Now as mentioned in this post, put the +/- pins bit closer and tried unplug and no issue observed so far.
Thanks. :good:
I too have the same issue. I tried to charge the battery with some direct USB.
Today I dropped the phone on my bed from 2' height and it got restart. But its quite surprise to see the effect of the USB plugin with the battery connector loosing up
I am thinking of putting a small alumunium wrapper on the +/- connector. Let see.
Last night I was charging my S4 in my car adapter, but noticed the cattery was still going down. I went home and plugged it into my AC (wall charger) and went to bed. The next morning the S4 was dead and couldn't charge. The only solution was to plug it in my computer and went an hour for it to get some charge back.
I have a root i337m running rootbox 4.1, and I went into TWRP to wiped the phone and installed the ROM again - no luck.
Is this a battery issue, a software issue or a whole device issue? Thanks.

I don't think its a rom issue. I tried charging via USB as well and had phone charging a few hours and it ate crap. So I only charge via AC outlet only. USB charges but at a very slow pace.

I made an error in the OP - I meant to say I left it to charge on the wall and I got nothing.
Right now, the charge light doesn't even come on if I plug it with AC.

Maybe see the results by changing the charger you're using?

I've tried 3-4 different chargers and cables, same issue. Charges slowly through PC,doesn't charge at all with AC. Did a factory reset after reverting to stock FW, no luck.

I doubt it's a ROM issue, but there's no harm in reverting back to stock to see the results (assuming you've backed it up). If it all fails, i think you should unroot and send it to Samsung for the warranty. Software problems are somewhat easier to fix here than hardware, so it may be the best option to let Samsung handle it.
I had similar problems with my Note 2 before and now with my S4. What I found was, sometimes the usb cable wasn't tightly plugged into the wall charger. Once I've made sure of this, I've been able to charge (AC) every time.
I found this article that indicates that the S4 is looking for special sauce on the D+D- pins.
http://www.anandtech.com/show/6914/samsung-galaxy-s-4-review/2
Obviously the Galaxy S 4 will charge with any USB charger, but the charge time will simply be longer. Samsung uses a voltage divider and signals the presence of their own charger by sending 1.2-1.3 V across the D+ / D- pins, this is similar to what Apple does with 2.0 or 2.8 V across the pins for various USB chargers they've shipped over the years. This signaling is essentially Samsung's proprietary tablet charging signaling which they've employed on the Galaxy Note 2 and now SGS4, in fact the two use the same exact charger, so it's worth tossing out your old ones and getting the appropriate one to take advantage of the faster charging.
However I do not believe this to be 100% true. I think not all chargers will work..
I took a charger that is very vanilla (Wall charger but the D+D- pins are NC) and it works with the S3 and NEXUS7 but does not work with the S4.
This charger uses a stock USB cable so I took a wall charger that had gone bad but had a dedicated cable and hacked off the end and wired up my own cable...
That works! So it appears that the S4 will only charge properly with certain chargers that do something to the D+D- pins (either shorting them with a resistor like the article indicates
I then took a look at the cable I used to replace. It is a Motorola cable and it has the ID pin pulled high built into the cable... So I suspect that is required for the phone to work... But to fast charge it will need the special sauce indicated above!
Had the same issue and found the solutions which worked for me. Go into the developer mode and deactivate the usb debug mode.
Had the exact same issue. I took a soldering iron to my charging port on my phone. Problem solved. The ID pin had a bad joint.

I have a strange issue, my s4 is detected by pc, charges normally with usb ( wall or pc charge ) my battery is full but when I take the cable from microUSB port and s4 should work with the battery, turns off and consumes no battery, it's like refusing to use the battery and that it is full! battery checked on a sph l 720
I've tried installing other roms with safestrap but I still have the same problem, refuses to consume battery and while the battery is at 100% ,my s4 shows 0% if I disconnect the usb cable... game over. However, I can be on the safestrap menu for hours only with the battery, no problem, is a problem of rom I think but did not know how to fix it .. : (
I'm having the same issue as the original poster. The USB port is good, charges fine when connected to PC (although much slower because of different mVS). Have tried amidst everything and nothing fixes it. I've turned debugging mode off and back on, restore to backup, complete wipe and reinstall of 2 ROMs with and without apps, fix permissions, different kernels, different USB cables... The adaptor is in good condition. But when plugged in while on my phone doesn't recognize that's it's connected. Previously out would give a false charging reading. If off sometimes I got the grey bar battery but note is just vibrating every few seconds. Idk what to do...

I'd guess it's the charger. Get a new one

I had the same problem. S4 will recognize charger as USB charger, not AC. solution was to clean usb port connector, was some cloth covering wires. then restarted and worked ok
I am having trouble charging the phone the same way. I have reset the phone 3 times and still can't get a charge.
Hi there,
I have a big problem with charging my Galaxy S4. It only charges with my notebook USB Port, my AC-adapter does not work.
In the battery menu I can see that AC is connected, when I plug my adapter in. But charging does not work with my device.
Over USB I can charge slowly. This isn't a software problem, I have done some resets and firmware changes since the problem.
Maybe my phone got a little bit wet earlier. Could this be the problem? Can I fix this with changing the USB port part of the hardware?

Yes, I tried another cable but had no success
I dunno if I can ask it here, but i don't charge over usb, i mean it just "hold" the power level for me. Is that normal ?
Is your AC outlet working ?
Having issue where S4 only charges with USB and vibrates when using AC charger
I've been having some issues with my S4. I did recently get it a little wet, but it's working fine in all cases except charging. I have my phone next to my bed charging every night. I noticed it was dead one morning, but I figured I didn't connect the charger properly. The next night I noticed it was vibrating every 5 seconds or so, but the phone had turned off due to a low battery. Very strange behavior.
I realized that it would start charging, but it would stop between 1-3 minutes. The the phone would vibrate and not charge.
I've ready MANY posts from others with the same issue and someone mentioned their phone charges over USB. Seemed odd, but I tried it and voila, my phone charged perfectly. I have many samsung cables, none of which work. It's definitely not the cable. I can plug a samsung cable into my phone connected to AC and it doesn't work. I pull the USB portion out of the AC charger and plug into a computer and it immediately and consistently charges. The battery holds its charge as expected, so it doesn't appear to be a battery issue.
I've tried the developer mode options - no luck.
I've tried bending the charging prong - no luck.
I've tried blowing out the charging port with compressed air - no luck.
I recently got an update pushed to my phone (Sprint), but I don't think it was happening right after the update. Seems like a likely software issue.
I did get my phone a little wet recently, actually it was my young children throwing water at me.
I've read so many posts and nobody seems to have a good answer for this issue. Any suggestions are appreciated.
Hi
I have the Galaxy S5 for about 1 month now and I like it very much. But two days before, I noticed issues with charging the phone through the AC Adapter (Samsung original USB Charger) - the phone did not charge during the night. So the phone stopped charging with the wall charger. I tried out many other USB chargers and also USB 3.0 cable. Without success!
It charges just fine when it's plugged into my laptop or desktop PC.
When the phone is turned on and I plug the charger in, nothing happens. The battery condition in android is still "discharging". But when the phones is turned off and plugged into the wall charger, it vibrates in intervals and the screen stays blank (the little battery animation doesn't appear). Removing the battery and replacing it does not help. I tried almost everything...
Has anybody an idea? Otherwise it seems to be a hardware problem. Same issue also here: Androidforums
I'm on OMEGA 5 ROM now with OMEGA Kernel. I cannot believe that the OMEGA Kernel has something to do with this issue.
Thanks for any help

It seems that it was a hardware problem, probably because of some water inside the USB connector. After some days I blow out the socket with a spray duster and since this time, the issue never happened again. :good:
I think, I will never test the water resistance again...
Did water enter the usb port and was the flap closed or not?

The flap was closed of course. I don't know if water has entered into the socket, but I think not.
One day after my post, the issue happened again. Now, I have updated to OMEGA 5.1 and flashed the Samsung stock kernel instead of the Omega Kernel. Now, the issue never occured again.
I cannot believe that this is because of the kernel, because the issue was also when the phone was turned off.
Now for 1 week, I never encountered the problem again
Suddenly my Galaxy S5 doesnt want to charge on the wall. When I plug it in, it shows the bolt sign, then it start vibrating every 2 seconds. I tried changing the cable, the charging box, the location, and still no luck. Then I tried to connect it to my laptop and it worked, it works on my laptop even tho now it doesnt recognize it. So I think its not my charge port, cause it works charging it in my laptop. Its not the battery, i have 3 and I tried with all of them. I tried the smack method with the power buttom and no luck.. what can I do?

i had a similar prob, see if phones usb port is dirty/corroded or has bent pins.
i bought my s5 used thinking i had to swap out the usb port
i cleaned mine, battery removed, after cleaning mine out w/a steel dental pick, exfine sandpaper on the pins, and tissue dipped alcohol w/toothpick and/or dental pick i got it working again 99% of the time, b4 my endeavor it was only working 5% of the time.
start w/just using a toothpick or something not metal to clean it out and even the alcohol method and see if it improves.
