Introduction

I am Arijit Guha, a computer science engineer by profession and I have taken apart every gadget I have ever come across in my life. I own this device and this one is no exception.

This teardown is not a repair guide. To repair your Asus Zenfone 2, use our service manual.

  • Unscrew all the 14 screws. There are two strips of adhesive running top to bottom beside the sim card slots so be patient and slowly remove the rear cover.

Image 1/3: The sub board has the antenna terminals also and prior to removing the battery, the antenna cable needs to be removed as well. Gently disconnect the coaxial cable from both the motherboard and the sub board.

  • The battery connector is the connector at the right of the motherboard. Above the battery, there is a bridge connector which connects the mainboard with the sub board at the bottom. So remove both the cables. There is a slight adhesive below the battery. Cut through it with a plastic spudger and it will come out.

  • Remove the copper tape adhered to the mid-frame. The motherboard is held to the mid-frame using 4 plastic clips. I found that starting to pry up the motherboard from the right is easier than from the left. Just apply mechanical sense and you will get the motherboard out in no time.

  • The battery is rated at 3.85V, 11.5 Wh. The capacity is 2900 mAh minimum and 3000 mAh typical.

I want to know the dimensions of battery, and if a bigger capacity battery will fit in.

I will have to measure the dimensions. However, I am sure that a bigger sized battery will not fit. If battery of same size but of higher capacity can be arranged, I am not sure if it would work at its full potential as the software is programmed to stop charging once the charge capacity reaches 3000 mAh (for this phone).

I want to know where the battery sensor is so i can turn it off. My zenfone 2 got a bug that the sensor "thinks" the battery is in a very hot temperature, and i was told that turning it off would solve the bug.

  • Realtek ALC 5647 audio chip.

  • Broadcom BCM4339XKUBG - Dual band WiFi controller.

  • The proximity sensor, notification LEDs and the 3.5 mm audio jack are all soldered to the motherboard.

  • The front and rear cameras can be easily removed from the motherboard

Does not work fast charging, which is 9 volts, the usual 5 volts works, can it be from the power controller pmb6830. Email. Lukyanov_aleks@inbox.ru
