Nexus 4 (non-rooted) battery calibration doubt !

Guys... I have a nexus 4 which is not rooted yet, running on stock android OS, android lollipop 5.0.1.
I know the manual procedure to calibrate a battery (charge till 100% in one go - discharge without charging in between or connecting phone to any device by USB till phone turns off - again charge from 0%-100% in one go). I do it with the stock charger provided with my phone.
But now I have a doubt.. What if I use a turbo charger to calibrate the battery !
Will the battery be calibrated efficiently as the charging is a bit fast with turbo charger.
And also.. What if I calibrate using a power bank, I have 2 power banks.. One charges phone fast like a turbo charger.. Other one is a bit slow.. Like the stock charger...
Will there be any difference between the battery calibration done with stock charger, phone connected to PC using USB, using turbo charger, a slow charging power bank and a fast charging power bank ? Does charging speed affect battery calibration ?
P.S. - While charging phone using both the power banks, it shows charging on AC.
Please someone clear my doubt.
Thanks

Charging Issues; Need advice

Hello,
First off I want to preface this by saying I have my bootloader unlocked, rooted, running a 6.0.1 ROM.
This past weekend I noticed that my phone wasn't charging on a generic 4 port USB charger that I have. Made sure it had power, tried it on my tablet I had laying around, and eventually got it to charge using a different cable. No problem, stuff like that happens. Noticed it was "charging slowly" Hmm..wonder if the USB charger is going back. Tried it other places, but always getting EXTREMELY slow charges. Unfortunately I had my OEM charger at work at my desk so I couldn't try that but I have a QuickCharge 2.0 car charger that I tried. I plugged it in there and I was actually LOSING charge at what seems like a faster rate than just a normal drain. WTF!?
Got to my destination (going to my buddy's house) and tried a few of his chargers; same thing, "charging slowly". Made it through the weekend, got home and the problem is still going on with all my chargers.
So today, I get to work to try my OEM quickcharge and it drains my battery as well! Oh boy. This is bad.
Anyone else experience this? Since I've unlocked bootloader and no extended warranty AND the fact that Moto Support is god awful anyway, I'm screwed when it comes to professional help. Anyone have luck opening up this beast and fixing anything? Any help or guidance would be very much appreciated.

My phone isn't charging very well either. I went out to do some errands and phone was on 84% saying it'll be charged in 35 minutes I came home three hours later it's still on 84% with 35 minutes to go and burning up to touch. This is already my fourth Moto X in the week.

Fourth with issues? Hope it's not related to the same charger.

Not the same charger but all four different chargers the phone comes with. I ordered it on Amazon with next day arrival and the first two phones had dead pixels third one was reading 138 degrees with ampere while charging and would stop and fourth (current) refuses to charge past 84% unless I have the phone off I noticed. I unlocked the bootloader on this current one though so I don't think I'll be able to exchange it now

Question to OP: DId you ever find a resolution? I have recently noticed that my XT1575 (currently restored to stock 6.0 but still unlocked) actually LOSES charge while "charging" (as reported in Battery setting) in my Car (12vDC) and on my motorcycle (12vDC). Granted, I am running GMaps and streaming music running, among other apps... In fact, I just saw the charge drop from 74% to 68% in about 15 mins while driving this morning... On the other hand, when plugged into AC Turbo charger, I can run all those apps and then some, and charging, the battery charge goes up 1-2% per minute... Wondering if anyone else has seen similar issue when charging via DC current?

now that I think about it, its DC going into the phone regardless of the source, so the type current is not a factor... so assuming I don't have bad cables, what could be causing the difference?

Upon further research I just discovered and ordered a Qualcomm Quick Charge 2.0 capable car adapter... I'll bet the "standard" usb power the phone can draw from a cheap car adapter isn't sufficient to effectively charge on top of streaming, GPS mapping, Bluetooth stereo and screen on... Lets,see what the new 2.0 QC adapter can do next week....

I've noticed issues with the charging port. I have two brand new 25w turbo chargers and neither of them connect/charge my phone. I got an OEM USB cable and connected it to my old Droid Turbo charger and that is the only charger that works for me. Bummer. Was considering sending back the phone to moto, but I'm unlocked and have a feeling they would not repair/research it...

You can download an app called "Ampere" it will actually show you the charge and discharge rate that the phone is doing. Might help out in determining what is wrong.

For those experiencing issues with the device not charging to 100% when it is extremely hot, this is normal behavior. This is from Motorola...
Some facts on battery temperature
* Devices need their space; There are no on-board fans, cooling relies solely on the device being able to dissipate heat through the air. To help cooling, ensure the device is not in a pocket, purse, carrying case, or direct sunlight.
* Normal temperature is (97f) ~36c
* A user will begin to sense a “warm” device at 106f (~41c) and it will seem hot at 109f (~43c)
* Cool Down Mode kicks in at 152f (67c)
* Batteries with temps => 113f to 140f (45c to 60c) will not charge to 100% capacity
* Battery temps >140f (60c)will not charge at all

Wireless charging not providing as much juice as charging via USB cable?

Does charging the phone via the Samsung official wireless stand (or any other wireless chargers) causes it to have "less overall capacity" on the battery compared to charging it via USB cable? E.g. Once charged to 100%, does wireless charging provide less capacity compared to charging it via USB cable?
Note that I'm not talking about charging speed or rate, I'm more interested to know about the battery's overall performance when charged using wireless vs cable.

Sorry, misread your question the first time.
No, 100% is 100%, whether you charge wired or wireless, fast charge or slow. The battery tells the phone when it's full, and the phone tells the charger to stop charging.

I always seem to have better battery when I use the plug instead of wireless.

That's what i'm thinking! It's rather strange that this topic had never been raised before.
Anyone else?

Tell you what I've always wondered but won't try it myself, what happens when you plug it in AND place it on a wireless charger!?

Got my wireless charging stand and it said it would take 2 hours, 20 mins to charge to 100% from 0 compared to 1 hour, 33 mins from plug

Slow battery charging & charging stops after turning the screen on

Hello, guys. I hope you all are great.
I have a concern... I don't know wether the issue I am facing is specific for the XT1575 or is a general android problem. Here it is:
I have a Moto X Style and I am facing this problem: slow battery charging. There are 2 symptoms that I noticed:
1. When I turn on the screen after starting charging with the screen off, the cell phone stops charging (using fast charger or ordinary one). To continue charging, I have to unplug and plug again and again.
# I believe the fault is software. But I am not sure about that.
2. About 5 days ago the turbo charger (and common charger) is charging very very very slowly. It is not normal. To charge 1%, it takes about 20 min. I ran the Ampere app and realized that the current during charging is between 230 and 260mA. If I am not mistaken, using the turbo, it should be at 1600 to 1800mA.
I realized that fault after a trip. In it I needed to charge the phone in the USB 5V car charger and did not charge properly (same symptom described above).
What have I already done testing?
- I had a let the battery drain 100%, so that I started to charge. Nothing has changed.
- I had tried charge using the fast charge that came along with the cellphone and ordinary ones. Nothing has changed.
Has anyone had this? Is there any way for me to go and fix it?
The cell phone is awesome, although the battery is your biggest con. Without the turbo charger it gets me some doubts regarding if I can still have it...
I really appreciate your help.

One extra update: I have just factory reseted and everything is still the same as stated previously.
Something says to me that the issue is software. The reason is that I use a pin code to protect my device and after I turn the screen on (after typing the pin), the device stopped charging. So that I had to unplug and plug it once again to continue the charging.
The thing is that after I factory reseted and realized that the issue continued, I tried to suspend the use of pin code.
Result: the second flaw stopped. I mean that after turning the screen on the battery continue to charge normally.
Now the fast charging pretty slowly still...

You most likely have a bad cable or adapter... there is no known software issue with charging on any Moto X device.
Less likely: bad USB port in the phone or bad battery
Even less likely: bad main board in the phone
Find a friend with a Galaxy S7 or S7 Edge (just saying because they common) and plug into their stock charger, it should pop-up the turbo charging toast messaging within a couple seconds.

I see... So, I agree with you. Even based on that my Moto x is really new. No more than 1 month...
I will look for another turbo charger and try once again.
Oh, and one more thing, even the cause may not be related to software, I intend to downgrade to 5.1 and try once again. If nothing occurs, I will update to 6.0.1 and move my life on.
Thank you in advance!

Don't do that... Why on earth would you want to do something as dangerous as downgrade?

I don't know. Maybe the fact that it can be a software issue...

It's not software... But I'm no expert either. If it is software you are the first person to discover it. Try a new charger or just connect a buddies to test it.

Unfortunately, I believe that the issue is hardware related.
I charged with another fast charger and problem persists...

Slow Charging

Nowadays, my battery charges slower as compared to before. I used to get 20% change in 15 mins and 40% in 30 mins, but now it charges 30% in 30 mins and 12% in 15 mins.
What can be the issue, is there any problem in charger or I should replace my battery????

Also, is this with the same turbo charger you mentioned last time or with a different charger?

Then change charger (either buy a new turbo charger or see if someone can loan you one) and test. If the battery charging improves, it's your charger/charging cable. If not, might be your battery or power management.

What if I take my bill (not mobile) to service centre to get replacement of charger. Is IMEI written on bill?

I don't know if your IMEI is written on the bill, you could look it up (think the IMEI is usually written on there, so they may check your device warranty. Seems that accessory warranty is tied to your device warranty).
As for power management, could be software or hardware (either the system or the chips controlling the power supply).
Simplest thing would be to buy a new charger if you can and test. I recall you mentioned that a normal charger works so perhaps your Turbo charger is not working properly, but without testing with a good known/new turbo or QuickCharge charger, it's difficult to say.
EDIT - also don't forget that your charging rates will depend on how empty/full your battery is, as well as how hot your device is and if you're using it.

Yeah my previous issue was fixed, I tried keeping my phone for charging for whole night for two consecutive nights and now there is no quick drainage.
I will take my friend's Moto G4 plus (in warranty) if issue persists to replace charger.
Also there is a visible damage in change's wire as it's left most node is shifted lil bit inside, hope changing cable fixes my issue
