INTERNALS - N5 Power Routing - Nexus 5 Q&A, Help & Troubleshooting

Recently disassembled and replace the original battery but have been having issues with the reassembly. Battery indicates charging and wireless charge status but does not hold. N5 must be powered via USB/external batt. and instantly powers down upon disconnect.
Is anyone familiar with the internal components to troubleshoot this issue? Ribbons look properly connected visually, however there is obviously an issue. Maybe a internal ribbon pinch/break somewhere?
Please reference photos to indicate how the charge process works, much thanks!
Beers on me for the genius with the solution

Are you sure the replacement battery is good? What happens when you put back the original battery?

Original battery does not work either

Did this problem ever occur before changing the battery? Do you have a way to check to see if the replacement battery is working properly such as trying it in another Nexus 5?
I'm admit that I'm just guessing. I've changed the battery many times on the Nexus 5 using 3rd party and OEM batteries but never experience what you are experiencing.

Charging problem on stock ROM?

Hello,
My wife and I both have a Nexus S, which are both almost 2 years old now. She has always been running stock ROMs and only updated when there was an OTA update available. No rooting, no nothing I however tried as much as possible and currently running SlimBean 4.2.2 Build 5 :good:
Since 3 days now, the battery in my wife’s phone isn’t charging anymore. I tried the following:
- Use my charger and an old Nokia charger: doesn’t work
- Put my battery in her phone: doesn’t work
- Put her battery in my phone and charge mine: works like a charm
The last one’s the solution for now: at night I charge one of the batteries in my phone and put it in hers, while at work I charge the other battery from my PC via USB.
Based on my ideas I’d say that something in the USB-port on my wife’s phone might be broken. However, there are 2 phenomena that I find rather strange:
- When her phone says it’s time to connect the charger, I take out the battery and put it in my own phone. I power up and the battery level reads somewhere between 60 and 80 percent
- When I power off her phone and connect the charger, I’d expect to see either the charging symbol or nothing. But none of these: it powers up as soon as I connect the charger
I don’t know about the first issue, but could it be the battery stats might be corrupted? The last issue makes me believe that the USB-port is at least not completely disconnected/broken.
Has anyone got an idea what the issue could be? I wouldn’t want to work on her phone rooting it if it isn’t necessary, but on the other hand she might be better off in various other ways as well
Thanks in advance,
Pieter

Being completely stock and never modified, I'd say it's the usb.. Have you tried the OEM connector for the computer?..
1. I would take it to a shop
2. You could also try cleaning the contacts
3. May do nothing but if you take the battery/sim out and hold the power button for a minute, this is supposed to completely power down the phone, and then reinstall sim/battery and reboot..
4. Use this as an excuse to modify her phone (telling her that you can put it back to stock if she doesn't like it)..
This happens a lot on my phone, .. Be careful with my solution, I hope it works for you..
Basically inside the usb port on the phone, there is a flat pin. On my phone, this pin ends up bending downwards towards the bottom of the phone.. What you could do is get a very thin knife or a swiss army blade and just try and lift the flat pin in order to make it locate in the center of the usb port (hole) .. The issue being the pin doesnt connect with the charger ..
I hope you understood this
PS: Don't snap it !

Nexus 5 won't charge the battery, shows -30degrees and cold temp

Hey All,
i have a nexus 5 running android 5.1.1, which recently i have encountered some battery issues, the battery drained very fast (6-7 hours from 100% to 0%).
but then, it stopped charging the battery, no matter what i changed - nothing worked! (new cables, different chargers and so on).
yesterday i have bought a new battery and replaced the original faulty battery, but nothing is changed, the new battery won't charge.
i tried to charge it when the nexus is on or off, doesn't matter, same result...
i am very frustrated from the situation, and basically can not use the nexus any more..
one more thing, i tried also google suggestion (when the cell is off, to press power+volume buttons, and then scrolling down to shut down and inserting the charger - >didn't work for me).
i tried to upgrade to Marshmallow (6.0.1) but there is not enough battery power to allow it...
when i dial *#*#INFO#*#*, and check the battery properties,
why the temp is always -30 degrees for the two batteries?
Is it a sensor issue?
do you have any suggestion?
Thanks!
anyone?
i will really appreciate your suggestion..
Connect the phone to a Windows machine and look to see if any new devices appear in Device Manager.
Thanks for the reply.
I connected the nexus to my laptop, it was recognized and i could reach the storage, but the battery remained the same, not charging ..
So the nexus 5 appears in Windows explorer? Possible charging port problem?

well, maybe. havn't tried it so far..
have you encountered this issue of wrong temp alert of -30 degrees for other users ?
and replacing the charging port solved it?
I haven't encountered the battery temp issue.
Since the old and new battery behave the same way, there wouldn't be too many culprits which is why I mentioned the USB charging port. Has the ever been dropped? Any way you could test the batteries in another phone?
the problem was resolved!!!
finally, after so many hours trying to make it work, i encountered a thread here in XDA which explains that the sensor is located on the cable connecting the battery to the motherboard.
Apparently it was a bit loose, so i put something above the connection and put the cover tightly.
then, the temp was reasonable again and my nexus was coming back to live!

Hey, I have the same same problem , what did you do to fix it? I've been almost a year without using my nexus because it only works when it's plugged. Can you tell me what thread did you read or the solution? Thank you
See my last post....
Anyway, The problem was at the connection port of the battery - when you remove the nexus cover, you will see that the battery is connected by a connector with 9-10 pins to the board. Apparently those pins weren't connected properly and were loose, so I put something from above to make some pressure on the connector, then screw back everything and close the cover. Since then, my nexus is working great!
I hope it will work the same for you...

Battery image that appears and then disappears

Hello I have this problem: the tablet is completely discharged and when the attack power appears to me the image of the battery but turns off almost immediately and then reappears the same image, and so all the time that the cable is connected, no reloading in fact the tablet. The tablet power on hand, makes me see the samsung screen but being drain properly turned off, even with an attached power cord.
If I understand your post correctly and assuming that you have tried various cables and chargers already, my first thought is that the battery connection internally needs to be checked.
Then there would be follow up things to check like the charging connection and the battery itself. There's a thread about screen flickering that describes issues with the battery connection inside the tablet. What is your situation with regards to warranty and your interest (and technical skills) in order to repair the unit yourself vs having someone else like a repair center do it?

I opened it and removed the battery connector. But the problem persists. You say that I have to bring it to service?
Yes flickering the image of battery, but non recharge the tablet.
yes is the socket connector of battery. i re-soldering it and now all ok. Thanks

Galaxy S5 Quit Taking a Charge

I'm trying to troubleshoot what might by wrong with my S5. I woke up the other morning and my phone was completely dead. It was plugged in, but no LED was on and the phone was not responding.
I've tried he various troubleshooting that I've seen around the internetz, such as:
removing the battery / discharging with power for 1 minute...plug back in and try again
use a different charger / cable
clean out the charging port (I used my air compressor to blow out any dust that might be in there)
I feel like I've exhausted all I know how to do. I do have another S5 coming in a couple of days, so I'm hoping to use that to see if it's either:
a problem with the battery
a problem with the charging port
something else?
My guess is that if the new battery comes in and I put it in my old phone, that will help me tell if it's the charging port or not, correct? My assumption is that if everything else is fine, then my old phone should power on.
I am a little nervous that it's something else though; I measured the voltage out of my battery and it was registering nothing the other day. When I plugged it into the phone and allowed it to charge (even though there was no indicator and the phone would not turn on) I measured the voltage again and it was registering ~2.8V.
Anyway, thanks in advance for anyone here that can offer any other guidance as to what I can look into to troubleshoot what the problem might be.
I've verified that another battery allows my phone to boot, so my guess is that it's the charging port.
How hairy are these to swap out? Is it a realistic repair?

ive cracked an S5 apart, and getting to the charge port isnt so bad if you can get the back plastic cover off, but you might have to remove the screen too. The S5 is waaaay harder to get apart than the early notes
You can get a wireless charging receiver or an external battery charger to charge you battery instead. I charge mine wireless as much as possible to help save the charging port for when I actually need it.

NO CHARGE - N5 power faulty

Hey guys,
So long story short I've recently replace the original N5 battery to an OEM one. Upon reassembly N5 does not charge or wireless charge anymore, must be powered via USB/portable battery.
Any thoughts on how to troubleshoot this? I've disassembled and ensured all ribbons are properly attached (but obviously am missing something). I've tried using the original battery and 2 OEM replacements to no avail.
Thanks, love the N5 and would be very sad if this is how I'll have to part ways.
ps. FYI I've been running the N5 through external battery for the past 4 months...
