NFC not working after battery change. Any ideas?

Hi everyone,
I recently successfully replaced the battery in my Moto X Pure after the original battery was showing signs of fatigue (charge wouldn't last anywhere near what it used to, would die suddenly from 20% battery power, etc.). I discovered today, however that my NFC is not working. Part of the process to replace the battery involves gently popping the NFC antenna off the old battery (the end of the flex cable with the NFC antenna is held by a drop of adhesive to the battery). I made a point of being careful when I did that, and with the phone now buttoned up again, everything else works 100%.
Aside from the obvious, "you must have broken it when you removed it from the old battery," anyone have any ideas as to why the rest of the phone is 100%, but my NFC isn't working? I checked all the relevant settings -- even turning them off and then back on again, no love. Does the NFC antenna connect via a harness that I would have disconnected to change the battery out? Does it even seem possible that everything else is working properly, but that isn't? Best to just try replacing the middle bezel housing with a $15 eBay special that includes a new NFC flex cable?
Thanks in advance for any ideas.
Edited to add: So, in looking at additional pictures of my phone, I came to the possible realization that the NFC flex that was attached to the old battery probably had to be attached to that exact same spot on the new one to make contact with the motherboard when the phone is put back together. I didn't even consider that it was just a pressure connection there that connected the hidden NFC antenna to the motherboard, and just used some double-stick tape to attach it to the new battery without paying particular attention to detail as to where it needed to be positioned. If someone can verify that I might be on the right track, I'd appreciate it. I'd hate to tear the thing down again for nothing since the back cover is a pain to get off, but this might be a simple fix.

Not sure if this is still an ongoing issue for you (I realize it's been a few months), but I just experienced this today, while changing my own battery--and for the very same reason as you. Yes, it does appear that the NFC module does need to be in the same place as it was on the original battery. I too learned this the hard way. Since the NFC module wouldn't stick to the new battery, I placed a piece of Scotch tape over it. Little did I realize, there are contacts on that module, that must interface with something else on the assembled phone. After a second disassembly, removal of the tape, and a check of the location in reference to the original battery, my NFC is working once again.

Samsung S8 recharge in pause battery temperature too low

Hello
I have a samsung s8 with a broken screen, after replacing the display the phone no longer charged the battery and gave me this message "recharge in pause battery temperature too low". I also changed the battery but from the same mistake.
Ask a repairer to say that you need an official Samsung software to unlock the phone and make sure that it recognizes the parts without voiding the warranty.
it's true
thanks

Any pictures? Most likely your charging board is damaged and needs to be replaced

My phone works now after changing NFC module...

0% 0mV with fully charched battery

Hello everybody
Phone: Motorola Moto 4g Athene. Bought in 2016 in the USA in BestBuy. There is no warranty now.
Firmware: I have used LineageOS. At the moment, the bootloader is locked and the firmware is official (see below)
Problem:
The battery indicator shows 0%. The application "Battery callibration" shows 0mV. I culdn't turn it on directly: after "hello moto!" it is turned off. I managed to enter the system only through the recovery. If you disconnect the charging from the phone, it immediately turns off, because it thinks that the battery is critically low. At the same time in the recovery it works as long and stable as need even without charger. The voltage at the ends of the wires of battery measured by the multimeter was 3.9. After the body stood on the charge it became 4.2. Looks like the battery is charging in normal mode. All other functions of the phone seems to work properly. It seems that the phone is OK, but for some reason "does not know" how many volts there are on the clamps of its battery...
Background:
The body is Motorola Moto 4g Athene. It heated a lot all the time after purchase. As a result, the official battery have dead after one year. I bought a new one from the internet. (I am not in the US now. Motorola do not certified here. So there is no official parts, stores and service centers). The new one also died in a couple of months. During the replacement of the third battery, the plug on the board broke off. The wires from the new battery had to soldered directly to the board ... The third battery also died in a couple of months, and I have bought a fourth. Soldered. Here this funny Bug appeared.
Attempts to resolve:
Initially, it was LineageOS 14.1 installed. I did a Wipe of everything except internal data. Nothing changed. Then I rolled back to native firmware with locked recovery. Nothing. I made a Factory reset. Nothing. I have resoldered contacts from the battery wires to the board 5-6 times. Nothing has changed.
There is an idea that I overheated something on the board. Charge controller or something else. Nevertheless I can’t understand why the body works normally, except that it does not understand how many volts there are in the battery?
As a temporary solution, I consider the installation of some kind of software, which would not allow the android to turn off when the battery is low. In this case, I will charge the phone every 15-16 hours and everything will be OK. Do you have any idea about such kind of software?
Any other ideas are welcome.

[Help] S5 G900T bootloop on battery, but boots Ok on USB power

hi all,
my S5 TMobile started bootloop while on battery, but when it's plugin to charge it boots Ok
it doesn't go to Samsung logo, no blue led yet, just rebooting
I have another OEM battery, but it's the same bootloop - so it doesn't look like battery is bad
my S5 after it boot on power can be disconnected from power, but it reboot randomly, mostly when an application is launched
I had to use charger to use my S5
what can I do to fix it?
I've waited for Asus zenfone 6 as replacement as I want unlocked bootloader, phone 3.5" jack, HDMI over type-c
thanks for the help

To be honest (and you may not like my suggestion)...
It looks like either an issue tied to the battery/batteries themselves OR the brass battery connectors on the device (the brass connectors your battery physically connects to on the device).
The OEM Galaxy S5 batteries, specifically, are actually known to have issues (as I've personally experienced and researched).
These issues "primarily" consist of (or are typically tied to) one and/or both of the following:
1) The ability to retain an appropriate charge within a fairly short period of time. Basically, they are known to have a short life cycle (I've seen it as short as 60-90 days myself).
2) The IC within the battery itself goes bad in one form or another. It typically results in an issue with the information that's sent to/from the device and battery. Yes, the battery specific information you see on your device is all based upon what the battery is telling the device.
I really can't state what WILL work for you because I would need to have the device to clean, test, etc... (and I'm not asking for your device either... LOL! ).
I've got 3 Galaxy S5 devices myself. 2 G900V devices and 1 G900T device.
I hope this was helpful for you and I do wish you the best of luck!

thank you for the reply.
Anything I can check for this battery matter? like any app and look at the info?
As I have 2 batteries and both acting the same, I'm not sure that both batteries went bad at the same time
yes, on external charger battery the phone is stable
yes, I cleaned by alcohol battery connectors on phone and battery
yes, I pushed a little phone contacts to make sure those touch battery with some
sure, I cleaned dalvik and cache - no this didn't have any help impact
could it be some internal connection from battery connector?
worst case I live with external charger for 3 weeks, inconvenient for sure

SM-T530NU "Overheating", calibration?

Have a Sm-T530NU that has misbehaved for a long while, originally the OEM battery was thought bad. Yet after it was changed to a new off-brand battery and working on and off for a year and some, the tablet has started misbehaving again, mostly not charging and turning off alone. And recently has started showing the temperature warning icon while charging while off.
So, I've opened it again and digged down, and discovered the battery connector on the PCB wasn't well soldered, the contacts danced in the pad, so I retouched the soldering with flux and a little new solder and it seems ok (I can recheck again later if needed be), so I tested the original battery with multimeter and seemed acceptable, so I installed the original battery back. Charged it for a while, and, again, warning icon for temperature while off, and it switches back and forth between charging and warning... I turned it on, and it works, but throws an error once in a while about being too hot and closes all apps... this, I think should be something related to cpu heat and not battery one... (also wasnt charging during this). So, I read online that some of these tablets with a modem have a service menu (*#0*#) but of course this one has no dialer, so I've tried several programs to try and get into the service menu, my idea is to see if it's possible to recalibrate temperature sensors, for battery and for cpu, but I've not been able to open the service menu by any means (the last mean I have is trying an intent initiated by am but the tablet is not rooted and there's permission issue for asking an intent of uid 2 from uid 0....).
My questions are:
1) Is it possible to get to the service menu of this model somehow? with or without rooting? Is it possible to recalibrate sensors from it?
2) Should I recheck the battery connector? would a battery "overheat" (caused by a bad connector connection to the sensor cable, or a miscalibration) cause app shutdown during run? or is it related to cpu/gpu overheat? I see some phoen models (S2) can cause this message from torubles with the usb connector/pcb, this doesn't sound too logical on my case, but, is it a possible source of problems for this tablet too?
3) If it IS a cpu overheat (though tablet feels cool to the touch) is there anything can be done to help with this issue? micro disipator maybe?
Thanks for any advice. I'm willing to try odd or hard stuff to fix this.
