Who has not tried on your Android smartphone to re-calibrate the battery? There are many methods that support it, refills on and off by consecutive and concatenated terminal, those that act on the famous batterystats.bin , eliminating it via recovery or dedicated applications (in both cases with root permissions).
However, this method would be ineffective, if not useless, according to a statement from an engineer Google.
On Google + In fact, Dianne Hackborn posted:
"The battery indicator in the status / notification bar is a reflection of the batterystats.bin files in the data / system / directory."
No, it does not. This file is used to Maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing Between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI settings.
That is, it has deeply significant things like "X app to wake locks held for 2 minutes" and "the screen was on at 60% brightness for 10 minutes. "
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your device more fantastic and wonderful ... more well, the unless you have some deep hatred for seeing anything shown in the UI battery usage. And anyway, it is reset every time you unplug from power with a Relatively full charge (Thus why the battery usage time resets at IU That point), I know this Would Be Easier Way to much to make it go away.
In short, the file batterystats.bin , located in data / system does not reflect the percentage of battery Android smartphone, but would keep track of each application, and the impact that has on autonomy. These data are displayed in the settings, use the information on the battery device. Batterystats.bin the file is cleared each time the phone is fully charged. The calibration then it would not impact on autonomy, neither improves nor does it show the exact percentage and actual battery life.
Another myth debunked so it was.
