0% 0mV with fully charched battery - Moto G4 Questions & Answers

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.

[Q] New battery, new phone, stuck at 5%

I just bought a brand-new Defy+, and I can't get it to charge at all. It started at 5%, and remains there. Of course, it's just out of the box, stock 2.3.6. I'm asking here because most of the threads I've seen address phones that are already rooted and using custom ROMs, with advice on how to go back to stock.
I've also got an old MB526, without a battery but on CM7.2. So I tried charging the battery in that, and get the same. Sometimes it dips to 4%, but that's it. Then after a while it gets to 5%.
Any ideas what I can do, or try? The crappy thing is that I bought it from Amazon in the US and had a friend bring it out to me in Cambodia. So there's no chance for months to buy a new battery or anything like that.
Seems like there is a problem with the battery, either the cell are short-circuited (could be because of an old battery) or the battery chip doesn' understand when the battery is full.
Usually it is possible to fix that by a full decharge-recharge, possibly with a different charger (like in your case).
If it is not the case, I'm afraid there's nothing to be done.
Thanks, @Lurkos. I tried to let it discharge, but the phone (both of them) powers off as soon as it's disconnected from the wall socket.
When you say battery chip, where is that located? On the battery, or on the phone?
Battery problem
Very likely a battery problem. If this is a $6-10 battery from ebay, then it is sure duplicate.
I ordered a couple of them from ebay.in and both turned out to be fakes.
I am still searching for original BF5X battery for my Defy.
The only solution for you to is to remove the battery and charge it with an external battery charger for this battery. I have done the same whenever the phone shuts down in the night and I cannot get it to charge after that in the morning.

[Q] Red Light - Charging without back?

So, I plugged my Nexus 4 into a generic car charger and it went black instantly. The battery was at about 92%. With the hope that a proper AC or computer USB charge connection would bring up the white battery icon and fix things, I stopped by an out of town T-mobile. The manager tried the button battery-reset (up volume + power for 60sec) and I googled alternatives and tried the - enter recovery by pressing those buttons for 15sec off the charger and connecting while still holding down the buttons - trick. Neither worked.
The manger seemed familiar with that and the other button pressing tricks, and said that really, my only real hope would be to reset/replace the battery, but that would void my warranty. However, although the T-mobile site claims my Google bought phone is under warranty (and I've been paying for it each month), technically, it isn't. Under them or Google (any more). So, I purchased the tools to open the phone, as well as a replacement battery. In the interim, I tried to use all the button combos and various charging connections to get it to come back to life. I *did* manage to get it charging the old battery. I know because the blinking red light turned constant for an hour or two, and the battery got warm. I can only guess that the battery was too damaged to keep the charge however, because I could never get it to turn on during or after. My best guess is that the software battery reset allowed the phone to send a charge to the battery - at least once.
After getting my tools and replacement battery, I managed to get the phone open (with great effort - I think there must be a difference between batches there). I removed the old battery connection and looked to see if I could get the charge icon with it unattached and on the charger. I couldn't. Reconnecting the old battery didn't seem to make any difference.
I was about to go through the process of prying up the old battery when I realized that you can actually connect the new battery to the board connector without getting the old one out. So I did that. Leaving it charging like that for awhile didn't do anything, so I decided to do another software battery reset and I'm letting it sit on the charger overnight. All of this has been without reattaching the back.
So my major question is - does anyone know for sure if the phone actually charges the battery with the back off? I know there are important circuits there - which seem to shut down the phone after the battery or google image when not detected (at least that's my deducement after reading posts). But are those connections also used in charging? The Qi goes though the back to the charger function, so perhaps that connection has to be there? I would like to try and find out though beforehand. It took 2 hours and two mangled guitar picks to get it open the first time, and the second may be just as trying. (And believe me, towards the end, I was not concerned with being gentle.)
I am also curious about the four prong battery connection. I've seen the post about charging the battery using external sources by connecting to the two outer pins. Does that mean the two inner pins constitute a second circuit between the charged battery and the phone? And if I find another 3.8v battery fully charged, I could perhaps connect that to the phone instead by wires and get it booted into recovery? As to why I'd want to do that, I don't recall the last dated CM version I had installed, so finding that in their folder plus pulling off everything from /data... assuming I replaced this with another Nexus 4, I might be able to save myself a lot of setup hassle.
In terms of the red light... it actually seems to be an error code. When triggered, it blinks 7 times, and on the eighth stays lit for a bit before repeating.

I RAN INTO A SIMILAR PROBLEM
I found that holding the power button for a while allowed my nexus 4 running stock Lollipop 5.1 to boot back up.
Have considered that you may have a faulty USB port ?
Just pop the old battery out install the new one plug in the charger and it will charge. You can boot up without the back on. The back contains the antennia.... and the NFC circuit board.
Good luck

Well, still no luck. I ended up putting the new battery in and closing it up to try the Qi charger, but all I can get is either 7 or 10 red blinks followed by a short solid light. No white battery charging symbol or anything else.
When you say a faulty USB port, what are you referring to? The cable works (though I've also tried my Nexus 7 one too) and even though it won't boot, my computer does recognize that something is there when I plug my phone into it (it just can't figure out what's plugged in - which is normal). I want to say that it's trying and failing to charge the new battery. At this point, I think the charger messed up more than just the battery.

[Help] Moto X Play won't show it is charging but the battery is working properly.

So, 2 days ago I was charging my device (XT - 1562 Indian Version 16GB) and when I saw the phone after 2 hours the battery was still at 15%... so I got into the battery options to check if the battery was charging and it was showing "Not charging"(SS attached) so I rebooted my phone and it was still showing not charging, I also did a factory reset and still the problem was not solved so I booted into the fastboot mode and there it was showing that the battery is charging. I was confused so I thought that there may be a firmware problem(6.0), so I downloaded factory images of 6.0.1 and flashed them(the BL was locked) and still the problem was there then I unlocked the BL and flashed 5.1.1 and problem still persists. Guys pls help me. :crying:
Also please tell me how can I flash 6.0.1 again via Fastboot mode. I am still at stock 5.1.1
Edit : Update : Now I have installed a custom ROM (CM 13.1 by Temasek) and now the phone is charging like it should but it charges till 82~85% and then stops charging. Cant give the phone to the service center because I unlocked the BL.

Thanks for the reply bro. I have updated the thread so can you tell me what is the problem.
are you using the original charger and cable ?? charge the Device when it's off then turn onforum.xda-developers.com/showthread.php?t=1782420
I'm having this exact same problem on my xt1575. I bought it from a nice dude on Swappa, but he seemed pretty green concerning phones in general. He rooted/unlocked it, then appears that he kept the stock ROM while flashing the franken kernel. I didn't notice this for the first day or two as I opened it and poked around for some signs of something loose/water damage: nothing.
I couldn't sleep last night, so all morning I've been doing what I can to play around with clearing caches, flashing different ROMs, and anything else I can find in the software side, but aside from somehow getting it to get past the previous cap of 4% to a whopping 25% before slamming down to 11% (percentages waver constantly), I'm stuck and desperate to figure it out. I've even tried the stock turbo charger, the stock charger for an old Moto X 2014, and as of writing this just now a Samsung quick charger for the giggles.
I have parts for all kinds of Moto X 2014/Nexus 6 lying around, so I took the risk of connecting a Moto X 2014 battery up to see how it behaved. It read the battery level around mid-seventies and didn't seem to drop at any exaggerated rate but still kind of bounced around a tad. It would charge at times, but otherwise still wouldn't show the battery as being charged. I didn't think too much of it because the 2014 is of course a different model at a much smaller capacity, so I didn't want to try leaving it on the charger for fear of overcharging. The only thing left that I haven't done is hook up the Play battery to another motorola because I don't have any screens to monitor progress and see how consistently it reads to determine if it's the battery that's somehow gone wonky.
So in summation/where I'm at right now: I'm having this same problem; I've tried both hardware and software tinkering to no avail; I feel this is still somehow kernel/software related, but I'm not sure how to completely obliterate everything to start from stock. Please forgive how scatterbrained I am right now, I'm tired yet wide awake and irritated with the whole situation; there's NOTHING I can find in the forums or elsewhere outside of stock replies like "are you using the original charger?"
My moto x play not change in normal it only charge in factory mode that to 75-82℅ only.
Let it discharge fully then put on charge without booting up

I have tried after battery fully drain, still it's not charging again I am charging mobile in factory mode. Is there any solution please help me. In factory mode i am not getting signal.
So no change in behavior. I did notice that when in TWRP that the CPU Temp value is crazy, and any reporting software says the battery is at -23.8° C and always cold, even on a brand new replacement battery (obviously send like that is what's keeping it from charging). I even went as far as to put a heat gun on it from a distance to artificially actuate any sensors and got nothing. The one time it did report normal temps it charged fine for a whole day but hasn't returned to normal since. This **** is maddening...
I know this is a long shot, but have you tried resetting the battery stats?
http://forum.xda-developers.com/showthread.php?t=1699687
I had this problem but yesterday I can solve that
First I put stock firmware
Wait for fully discharge
And wait full shutdown
I put an moto g 2013 charger (550mA 5V)and led stay on around 5 min but not charge
After put Nokia n86 charger (1A 3.5V)5 min and not charge
After i put an orginal moto turbo charger
And start to charge wait for 9%
Turn on the phone
Clear battery stats with battery calibration app
Wait for full discharge
Wait for full turn off
I put a Nokia n86 charger wait 5 minutes vibrates and start to charge like the beginning
Any other suggestions or solutions? Still my phone only charges in recovery mode. I have a aukey fast charger. Tried different kernels and roms without success.
The solution with the nokia chargers seems really strange and i dont have that type of charger.
Regards
Someone fixed this? I have the same problem and can't solve it. I have cm 13 by temasek and the first time the x play charged up to 83% but after a full discharge and a clean of battery stats, I olny could charge it via factory mode, like in stock 6.0.1
I dont know why but after i opened the phone and disassembled the battery it worked after putting it back together. Disconnected the cable to mainboard as well as nfc antenna. Then carefully pried the battery out. Its slightly glued to the mb. Then I held power button down for a few sec as read in a different forum. Afterwards I connected power cable back but left the battery next to the phone. Booted the phone and charging worked. Than I reassembled the phone Ehen I was sure everything worked. I was about to change the battery but now it works. I flashed different Roms and kernels without any improvment before. After I got it working I flashed a nandroid backup of a resurection Rom image that didnt worked before. Now its running perfect.

So, may the problem be in the pins when the battery is plugged into the mb? I'll try that! thanks!
Still having this issue, the solution with the chargers didn't work for me, neither the battery solution, suggestions?
How to solve the problem?
Please
Same issue
My Moto X Play has the same issue. It will only charge in Factory Mode. I had this issue before at 10-11 months old and had it 'fixed' under warranty, now 2-3 months later the same issue has occurred. Of course the warranty is only 1 year...
Glad I am not alone in this issue but i wish there was an easy fix! Putting me off getting another Moto...
Same problem occurred with me( Moto X Play).
My phone was not charging, it was stuck in some percentage and was not increasing or neither decreasing while plugged in to charger. But when i put it into recovery mode, it charges. But that was not the solution to the problem.
So, i have tried factory reset.
but problem was not solved.
i googled for the solution, but couldn't find the right solution. And i was stressed (I have a girlfriend, and living in very distance relationship, for me a smartphone is very important).
And was thinking of buying a new phone but not the Motorola, but couldn't afford at the time.
At the same time, i thought of repairing it by myself, by fixing the battery properly.
Without thinking about voiding the warranty and Motorola support, i unbolt every screw of the phone. and finally , finally, finally i made it by removing the battery and fixing it again(charger was plugged while removing the battery and fixing, and phone switched off while removing).
And now my phone is charging properly.
Hope I have helped every person concern to this same problem.
Thank you

Battery dropped 20℅ during restart

Last few times lost lots of battery during a restart. Curious if anyone else has seen this or has any ideas. Thanks.
I appreciate its a late response but my moto x force is currently a paper weight as the battery has died. It started charging very quick and then if you restarted it would lose almost half its charge. Genuine moto charger etc. The battery eventually completely failed. Moto won't fix though, even for money, as I unlocked my bootloader and will not supply batteries. I am in UK. You have to get a dodgy Chinese knock off once your battery dies. Oh and this only happened after I took it on plane, so don't take your moto on a plane! Screen won't break but the rest of it can...
I never heard that phone, especially battery, breaks on airplane. In the matter of fact I already made about hundred flights with mine and so far so good.
HELP
My moto x force is with android 6.0.1 marshmallow without root, rom KINZIE_RETLA_DS_6.0_MPK24.78-13.3_cid12_subsidy-DEFAULT_CFC.info but twrp 3.0 installed. I have already tested on CyanogenMod 13 tbm and the same problem occurs.
Cell phone shuts off and reports little battery. I put it on the turbocharger and it's loaded.
That is, there is forced shutdown and inconsistency in the battery data. Would anyone help?
In general, fast/turbo charging significantly reduce batter life. Could be that your battery is already damaged/worn out.
When your phone shuts off, put it on the charger (normal/slow if you have) but do not turn it on. When battery is fully charged, remove from the charger, turn on the phone and put on the charger again to reach 100%. Procedure sometimes helps to let Android knows the real capacity of the battery. Which is obviously lower than system assume.

A mix of mechanical and ROM questions

2018 may be late in the game to become a new owner of a OnePlus 2 phone. But here I am. My main phone at present remains a Samsung Note 4, and I'm trying to get a feel for how this old (but not as old as the Note 4) phone can be repaired. My issues are a mix of battery, possible circuit board, and other problems / eccentricities.
The phone was given to me non-working. I have a minor-league reputation for rescuing phones, so thought I'd try this one.
First, I had to get it up and going. Nothing worked initially. I wasn't delighted to find out the battery is only accessible after removing two covers and about 30 microscopic screws. I reset it by pulling the small "plug" at top center-right and the phone decided to allow me to boot. I immediately (per instructions I found elsewhere here) went to fastboot and wiped the cache.
I did manage to install TWRP and the latest (as of a few days back) version of Lineage 8.1. But then the problems began again. The phone would suddenly, after charging for a while (and reporting a battery that was nearly charged), shut down. No charging icon showed on the screen.
Fast foward. Today, I got a cheap knock-off battery in the mail. It intially worked and I got it nearly charged. But after more spontaneous reboots I noticed something odd; in TWRP, the battery said only 50% charged while in Lineage it said 97% charged. So once again I wiped the cache and this time the ART/Dalvik cache as well (pointless, but ya never know).
This did get the two percentage reports matching up. And initially it got the phone working again. But alas, once again, the phone started the shutting down.
Currently, I'm leaving it overnight to charge - if in fact it is charging (how does one tell)? If that doesn't work, I'm thinking about using Odin to totally reflash the original version of the operating system.
Any other ideas or input - including laughing at me for bothering with this - is permitted.
I will say that the engineering of this phone compared to the older Note 4 leaves the Note easily the winner; to take its battery out is a matter of 20 seconds. Really not impressed with my OnePlus experience so far...
Thought I'd update things. After spending a day on sites (here and on the official OnePlus community boards) I tried any number of fixes. I'm reasonably convinced the only way to somewhat consistently start my particular OnePlus 2 phone is to:
1. Open it up, thus voiding the warranty (hehehe.... by now that's void anyway).
2. Unplug the battery's small plug at upper right-center of battery (a fingernail works fine, but do make sure the phone isn't plugged in!)
3. *Leave the back off* or at best gingerly snap it on but without attaching the screws. (Every time I did so, even after extensively using the phone while it lay on my sofa's arm and rebooting it numerous successful times previous to replacing the screws, the phone refused to reboot.)
4. I also cleaned the usb c socket with a wood toothpick and was a little surprised at how dirty it was; I did the same in a minimal way to the battery contacts.
5. I found no real use to having the actual OnePlus charger; I used it a bit but my best results came from the Samsung charger and a new (though cheap) usb c cable I nabbed via ebay.
Today I did get the phone going and intentionally wiped Lineage and installed the latest (2017) version of the OnePlus2 official os. It went on fine. I rooted it, installed apps, and (as mentioned) repeatedly shut down and restarted the phone, which promptly restarted with only a 3 second lag. I did this 5 times because one thread I found suggested this was an official OnePlus suggestion. (I rolled my eyes but did it anyway.) Played with the phone a bit, then shut it down again and screwed the back on. As noted, the phone suddenly wouldn't turn on again.
In summary, I'm not sure if this phone can be meaningfully resurrected. If I knew where what may be a short in it was, I could possibly replace that part. But I have little idea and am not quite the geek enough to sort that out. I am guessing at a short because without the lid or screws, it wants to work. It wants to be a good phone for me and I'll keep toying with it for a while longer.
Any suggestions appreciated.
Third post is a question for others:
Has anyone else experienced their OnePlus 2 working fine *without* the back cover screwed on, but as soon as it was screwed on the phone stopped working and wouldn't start again? And, if so, did they ever sort out why?
I'm going to make this a separate discussion.
Hey. I experienced the same symptoms with a "official" replacement battery I found online. Random reboots over and over again until I couldn't even turn it one anymore.
TWRP was always showing different battery percentages than OS.once I put back in my old but original battery that came with the phone it turned on again and it works flawlessly again.

This is something I've read, and may well do. It also, however, raises another thorny set of issues re battery calibration. I understand that sometimes new batteries have to be "calibrated" by being charged, discharged completely, charged again, discharged completely, and charged yet again and discharged. After that, things are supposedly going to run right. Trouble is in my case, the phone doesn't want the battery; it keeps stopping completely and not restarting. Either the battery stats are wholly inaccurate (says around 57% charged during those brief times I've had it up) or I need to go with your idea. Trouble is there the original battery from this phone is dated 2015; I hope it has anything at all left to give.

I'm trying this in desperation. The phone has gone completely unresponsive at this point, and I'm looking at having a technological paper weight. Hope I can resurrect it but the odds are not good.
Some progress, some regress.
Here's what I'm seeing. I can get the phone up and running again after extensive recharging. As long as I leave the back of the phone off - that is, both the inner and outer backs - it seems willing to keep running. As soon as I snap the inner back into place, not even with the screws yet, the phone locks up. Soon after, around 10 to 20 seconds, it shuts off. Sometimes it will restart and other times it won't for a long time, even after unplugging and replugging battery.
Has anyone else run into shorting or grounding issues associated with the back (inner, the one w/ 18 screws) case?
I am now back to a dead phone. A new (3rd party) battery is my current hope... charging it for over a day now has not yet led to the phone showing any sign of life.
One other question: I know both this cable and charger work, but as they are not the "original" OnePlus charger / cable combo, could that be the difference? I'd appreciate it if there is any clear evidence regarding this question.
The below article raises a disturbing possibility, based on the reality that OnePlus cables and chargers are - by OnePlus' own admission - non-standard and possibly could harm other electronics. But on top of that, and not well explored in the article, is whether or not OnePlus' charger/cable combo might even be damaging to the OnePlus 2 (and other OnePlus phones). They "assure us" this is not the case. Hmm.

I thought I'd update this thread with what may be the final installment.
I invested $70 in a highly bent but somehow still working second OnePlus 2 phone off ebay. (The guy had a great fall on a log story as to how the phone got bent.) Long story short... I gambled and won. That is, I gambled that the innards of the second phone would go into my first phone and that the first phone's screen would work. YES. And so, after playing amateur phone repairman, I have myself a OnePlus 2.
So many questions. Going to peruse this board now...
