Battery needs calibration, BUT-

Readmyquestionnotthenane · Jan 8, 2018

So after the research, and the answers some of you kindly provided I've whittled down two possible solutions.
1. Recalibrate my battery
2. Replace the battery
There's just one small issue with that. I don't want to replace the battery because it isn't that old and I know it still can be functional. I know how to calibrate the battery, but here's the bigger issue with that. "How can I calibrate my battery when it turns off at 30, 40, 50, or 60 percent?"
This is preventing me from draining my battery all the way to properly calibrate.
Maybe I misread the right answer. Maybe Iam missing something in between the lines here. Whether it is a simple misunderstanding, or replacement is required, I still need clarification.

What I have already done:
Some youtubers with an 'apparent' fix for this issue is to go into the phone app and type in *#0228# and quick start. I've tried doing this, and yet it didn't work. It didn't load itself into the menu that I saw in the video. Is there an issue here? Is there something preventing my phone from entering this menu? If there is something preventing it can someone tell me?

Id say this will be my last thread, unless further issues arise. Any answer to this issue will be well appreciated, I kinda want my phone back.

Hi, do you know anyone with the same phone? If so you could try their battery in your phone, at least it would tell you if the problem is a faulty battery, which to me it sounds suspiciously like. Phil

See, when your battery indicator says 30% and it shuts down at 30%, it means that your battery is actually at 0%, it's just displaying 30%...!

That's called a calibration error. Any sensor that isn't calibrated properly will give you incorrect readings. Similarly, the battery level sensor will give you incorrect readings if it's not calibrated properly. And that's what you're fixing by calibrating your battery.

When you buy a new phone, it will (mostly) come with a calibrated battery. But over time this calibration goes wrong. That's why you need to calibrate it again.

But remember, it is not necessary that calibration error is the real issue, you may need to replace the battery. But calibration is a common problem.

Well, these numbers sometimes can be different for every phone or brand. So there probably isn't any issue...

1. Seriously? So when the phone cuts off at any of the mentioned values it means its at 0%? I find that improbable, but not impossible.
I say improbable because it just seems weird how an application says the phone battery voltage is much higher, certainly not anywhere near 0%. Is it the calibration affecting the proper voltage number to be displayed?

2. I understand the value differs from each device but the problem with what you said is: "The video I watched, the guy was using the same exact phone." He was using a Samsung Galaxy Note 4 as I was. I even checked and see if I was entering it wrong.

Well i Dont know anyone with the same phone but I do know that a replacement battery for my phone is pretty cheap. So I will attempt to calibrate my battery again, however if it doesn't work I will buy another battery. I don't know if the battery is faulty (to the point it would cause a problem), and i find that kinda improbable. Its a possibility, no doubt.

Yes, it is...

Not sure about this. Maybe there are different versions of the SGN4. Maybe the code differs for every region or maybe the carrier.... Maybe the video was fake... Maybe your phone really has an issue...
I can't tell that...

When a battery reports 30, 40, 50% (or whatever), its probably at those stated voltages, but suddenly drops to nothing as soon as any load hits it. I've had them say they were at as much as 60% and reboot as soon as I launched the camera, like everytime. After the reboot, it would show 1 or 2%, then suddenly 0% and down it would go again. The fix, a quality battery replacement. Regardless of battery age, it is bad if acting like that.
