Relax and be free from anxiety Take back good sleep and help alleviate pain. Photo by Kyle Van Horn. I thought that "overcharging" was a myth? However there's a disadvantage in keeping the battery in its socket when the laptop is plugged in, but only if it's currently suffering from excessive heating caused by the laptop hardware. The A. Ideally, the algorithm for how to determine when to trigger the "reset" of the battery statistics.

But just to confirm, technically you are saying that the OS combines its hardware reading of voltage with preset values set by the vendor or read from the battery's chip to determine the current battery percentage using some kind or formula?
This definitely requires references or for starters where you found such a file! Understood I have read his post earlier batterystats. Battery calibration deletes this file, forcing android to get these statistics again. The statistics are collected from scratch.. In that way u will have proper battery indication think updated apps may consume less battery — user I do not understand!
Moreover, you still haven't said where it is storing the new information! Just that batterystats. I was expecting a detailed explanation of its working! Please be more technical! Refer here developer. However the article has proved to be very interesting and does answer few other questions. But nothing related to technical details behind battery calibration : — reubenjohn. Brilliant jay! Makes a lot of sense.
This was the answer I was expecting! However again it lacks backup references and has an overall ambiguity in its wording.
Once it's fully charged, unplug it and boot your phone. Android might not say it's at percent, and that's okay. In that case, plug the charger again and let it get to percent. Then unplug it. This cycle of full drain and recharging lets the chip calibrate its readings with the battery's charge cycle.
Battery calibration is purely about an accurate reading of battery life. It does not improve battery life. That's an old myth left over from the years before we had lithium-ion batteries, smart chips, and smart sensors in phones and laptops. Battery calibration does not indicate the health of your Android battery either. Wear and tear on a battery does affect its calibration, so it's a sign of how much use it's been through.
But battery health doesn't come purely by amount of usage. Another myth about battery calibration, especially with Android phones, revolves around the BatteryStats.
Bin file, found deep within the file system. You will find many fake battery calibration apps that claim wiping this file helps improve battery health. This is a flat-out lie. Google engineers have confirmed that the BatteryStats.
Bin file has "no impact on the current battery level shown to you [and] no impact on your battery life. In short, wiping BatteryStats. With all this said, the vast majority of Android phone users never need to calibrate their battery. The smart chip, plus Android's own smart ways of reading battery statistics, combine to give you an accurate reading of your battery. These smarter algorithms and sensors have made it possible for Android and iOS to calibrate the battery without needing the full discharge and charge cycle.
The phone can re-calibrate the battery based on when it hits the "low battery" mode, and if you charge it fully or almost fully. Such instances happen with daily usage anyway, so you won't need to calibrate your battery. The only time you need to calibrate a battery is if you get inaccurate readings. For example, if your phone shows 30 percent battery life, then immediately drops to 5 percent and switches off, that's an indication of an uncalibrated battery.
This also holds true while charging. When you have a low battery and start charging, sometimes the battery will charge up to 80 or 90 percent much faster than normal. But once you unplug it, with a little usage, it will drain really fast too.
