LG G4 teardown with X-rays by iFixit.iFixit

A teardown of the LG G4 by iFixit, the gadget repair firm, offers an insight into the hardware of LG's 2015 flagship.

Among the highlights, the back cover of the G4 can be removed easily when compared to the adhesive-laden back panel of other mobile devices.

With the ease in opening, the G4 places itself among devices with higher repairability score such as Nexus 5, BlackBerry Z10, Galaxy S4 and Note 2. iFixit gives the G4 a score of eight out of 10.

The handset uses a 3.85V lithium-ion battery that is rated for 11.2Wh, compared to the Galaxy S6 with 3.85V rated for 9.82Wh; the iPhone 6 using a 3.82V battery has a 6.91Wh energy rating. The battery is easily removable.

The G4 will not support wireless charging without a special case.

The model number mentioned on the midframe is LG-H811.

On removing the motherboard you should be able to get a better view of the following components;

  • Samsung K3QF6F60AM-QGCF 3 GB LPDDR3 RAM
  • The Hexa-Core, 1.8 GHz Qualcomm Snapdragon 808 SOC is layered beneath the RAM.
  • Toshiba THGBMFG8C4LBAIR 32 GB NAND Flash
  • Broadcom BCM4339HKUBG 5G WiFi Client
  • Qualcomm PMI8994 Power Management IC
  • IDT P9025A Qi Wireless Power Receiver IC
  • Qualcomm WTR3925 LTE Transceiver

The rear camera sports a 1/2.6" image sensor, laser autofocus, and optical image stabilisation. Besides, there is an IR blaster positioned to the left side of the microphone hole.

The teardown also suggests that many hardware components are modular and can be replaced independently.
