Calibration of batteries (Li Ion or Li Po, used in almost all mobile devices) is a myth
You can start using it straight away and charge as you normally did with earlier batteries

Looking for a consistent answer about battery calibration
Using calibration apps doesn't really help as the battery files in system (...
Firstly one needs to understand C-rate or charge rate. Quoting from the linked article
C-rate is a measure that governs at what current a battery is charged and discharged. At 1C, a battery rated 1,000mAh charges at a current of 1,000mAh. In an ideal world the battery would be fully charged in 60 minutes. At 1C, the same battery discharges at 1,000mA.
You don't need a calibration app for that. Just fully charge the battery to 100% (in one run), let it run down to below the 20% mark, the recharge it to 100% (again in one run without interception) – battery calibrated.
And as that describes a "normal day" with recent devices (take it from the charger at 100% in the morning, put it back almost depleted in ...
This App just removes the file "batterystats.bin" in the "data/system" directory. It has nothing to do with your battery life and also not the status indicator of your system.
It only keeps the Infos in the "Battery Usage" screen. It will also be resetted every time you connect to a power source.

It's a tough one to answer, as I'm not sure what version of Android you are running, and you have stated it may be a clone.
Find "Motion" and tap on it
Scroll down the menu and tap on "Sensitivity Setting"
Open "Gyroscope calibration"
Place device on a level surface and tap Calibrate
Download 'G-Sensor' from the ...
Android shuts down your OS before it actually becomes completely flat, in order to ensure it has enough power to do so safely and completely (which is why you can power it back up again, but then it shuts itself off again). Over time, your battery does need to be recalibrated as the system stats on battery usage get wonky and the battery itself won't store ...
Recalibrating your battery won't actually make it last longer. What it might do is ensure that the battery level display is more accurate, so that when it says it's at zero, it's actually at zero.
Personally, I used an app like Battery Calibration (requires root) and it seems to help. To be fair though, I haven't actually tested the actual levels myself, so ...
The purpose of calibration is to figure out how to compensate for how the components in your phone (screws, speaker magnets, etc.) interfere with the measured magnetic field.
The calibration process is based on the fact that you can separate the internal and external contributions to the magnetic field by looking at how the field changes as the phone is ...
The best method is the manual DIY method :D
Step 1: Drain your battery by using it normally until it turns off by itself
Step 2: Power-on your phone, if it wakes up and you see some power left, do step 1
Step 3: If phone is now drained to the point it can't wake up, Charge it to 100%
Step 4: Once fully charged, power-on phone, and charge it again. Leave it ...
If its totally un responsive then you need verify once your harware whether its an exact replacement or not as HTC Wildfire S digitizer comes in two variants
So match it with old damaged one and if they are same then the hardware will be faulty and you will need one more replacement.
First of all, I would like to thank everyone who helped me understanding what can be the problem exactly; I am posting it as an answer because this is what solved my issue.
The problem was neither with the charger nor with the USB cable. The real culprit was an extension cord which was offering very high resistance probably.
Since my socket is at a ...
At any point in space, the magnetic field strength and direction is the net effect of all the magnetic field sources affecting that point. The earth's magnetic field is one of them. Magnetized screwdrivers, cars, refrigerator magnets, etc. all produce fields. Fields are also produced by current flowing through wires. It's like pouring water into a glass ...
Compass calibration works by detecting the magnetic field intensity of earth. But sometimes due to strong interference from other electronic devices like transformers, compass sensor may get wrong idea about the magnetic poles of earth and can point in wrong direction.
So to ensure that, it asks users to recalibrate compass by rotating in figure-8 direction ...
Finally managed to fix this problem. Seems like performing the calibration with the use of a Goldcard solved it.
I'll leave the link to the instruction here for anyone who may have the same issue.
Please leave a message if you encounter any problems when going through the instructions provided in the link above.
There are slightly different opinions around on this topic. To fully understand the issue, one needs to first understand how LiIo batteries work (which goes a little too far for our site, so please read details on Wikipedia).
Lie Ryan is absolutely right: LiIo batteries don't take it well to be fully discharged.
It shouldn't be done too often. I'm not sure ...
As you asked for a calibration tool: The Playstore seems to have some suitable candidates, e.g. Touch sensitivity calibration. But while this might be helpful, the permissions look quite suspect: The only job of the app is screen calibration, but it requests permissions such as accessing your contacts, call phone numbers, read and send SMS/MMS, and more -- ...
You can't recalibrate, even if your device is rooted since the battery capacity files are coded in the kernel (see Where are the battery capacity files located?)
Since you don't want to install another app , the only preferred option is to make sure that you are alert and switch off the battery when it reaches 90% (difference of 200 mAh being 10% roughly). ...
Smart phone batteries last around two years of normal use. Once the 80% capacity is hit, batteries lose their charge quickly.
Even worse, the voltage decreases which causes unexpected shutdowns. Apple tried to solve low voltage with throttling but never informed the customer. Apple is now hit with plan obsolesce lawsuits.
For starters your device needs to be rooted ( see rooting )
One way could be to fool the system by pretending you have a smaller mAh capacity battery so that it stops charging prematurely (relative to actual capacity) but that's tough because the battery capacity files are hard coded into the kernel, so you need to "cook" your kernel. See
Where are the ...
Is there a way to calibrate the battery level in such a way that the indicator gives correct resp. useful values again?
No . Battery calibration is a myth and you can see this question for more. While the context of question is different, it answers why it is a myth
Bought a new battery, do I need to calibrate it?
Li Ion batteries don't suddenly die ( ...
I have this too, and likewise it has persisted after getting a replacement device. It interferes with panoramas and photospheres, cardboard and the like. No idea on a fix. I think I'll do a second replacement.
The voltage and current rating of your battery won't be the problem. It will be the quality and rating of the cable you are using.
Different qualities of cable will handle different amounts of current and this is what will allow your battery to charge at different rates (assuming a suitable charger is used).
The fastest type of cable would be a USB 3.0 ...
I guess you mean to physically wave the phone in a pattern of a three dimensional infinity symbol (or simply a figure of 8). This YouTube video gives a good demo.
Moto G2 has gyro in addition to what Moto G1 have. Hence it should work like a charm and the issue you are facing should be a calibration issue at a low level.

Calibration needs to be done after flashing a new ROM, but you can calibrate any time you think your battery is miscalibrated. This program does it by removing the batterystats.bin system file. The OS generates a new clean ...
Looking through the android source code recently (I'm new to android building and am still getting used to what makes android tick), I came across a file somewhere that had all sorts of calibration statistics and figures.
All of the figures are set by the vendor of the device itself. From how many mAhs the battery holds, to what values different device ...
I've tested the compass fields measurments provided by Android phone and found out, that if I rotate the phone by 180 degrees, the field doesn't change to exactly opposite, which must be the case if the sensors are correct. This might be due inner magnetism of the phone details or sensor reading inacuracy.
If you don't compensate for that and just use ...
