Explore the problems and methods of battery charging

1, the cause of the battery problem

Moto launched the defy mobile phone (that is, mb525, me525) after the big sale, followed by the upgraded version, defy+ (mb525+, me525+), this model was later renamed mb526 (for the unity of expression, I will be unified to mb525 and mb526 model). Mb526 over clocked CPU on the basis of mb525, increased battery capacity, increased battery voltage. Unfortunately, we now brush the third-party modified ROM based on mb525 development, they certainly do not know how to deal with mb526 Large-capacity battery, but with the way to deal with mb525 battery, which leads to mb526 battery charge is not full. (here explained battery judgment: charging stops because there is a charging limit voltage, that is, when the voltage reaches the specified value, it will not press up again to protect the battery, and the battery itself will report its status to the system. So there is such awkward situation on the mb526: the battery says, I am not full, add some voltage. The system says the voltage is already 4.1, it will explode. So it will continue to charge under the 4.2 warning line, and because the voltage is not enough, the battery will never be full.)

2, the principle of correcting the battery problem

First of all, we need to understand that the system kernel and SV version (the so-called BL) system kernel is well understood, that is, the version of the Android system. However, it should be reminded that the 2.3.4, 2.3.6 and the like displayed in the system information are not necessarily the actual version of the system kernel. Like the Miui system, no matter what version it displays, it can't change the nature of its 2.2 kernel. The MB526 is a system without a 2.2 kernel. All 2.2 core systems are based on mb525 and are not destined to solve the MB526 battery problem. So you can correct the battery problem by replacing the 2.3 core and battery files of the MB526.

When got here, I think you should have a clear understanding of the battery problem. Now let's talk about the solution. One sentence: "one-to-one correspondence", "row" to "row", "water" to "water", "where" to "where". It’s the kernel and battery files to be one-to-one correspondence, from the official package to extract the pairing, cannot be arbitrarily mixed with the licensed ROM extraction of the kernel and battery files, parallel imports of the water core of the battery file. It is recommended to consider extraction the kernel and battery files for the corresponding sales location.
