iFixit Teardown Time: iPhone 6s: Smaller Battery, Taptic Engine

iFixit, they of the more than welcome teardown fetish, have taken apart the iPhone 6s, and given us a closer look at the new handset’s innards.

First off, battery capacity is indeed down from last year, with a 3.8 V, 6.55 Whr, and 1715 mAh power source. It’s a small but notable decrease from the 1810 mAh battery in last year’s iPhone 6.iPhone_6s_Teardown_1

The display unit now weighs in at 60 grams, a 15 gram increase over the iPhone 6. The new capacitive sensors added for 3D Touch are the culprits here. The display assembly connection has been condensed into three cables, there were four in the iPhone 6.


There are a metric buttload of ICs on both sides of the logic board, including:

  • Apple A9 APL0898 SoC + Samsung 2 GB LPDDR4 RAM (as denoted by the markings K3RG1G10BM-BGCH)
  • Qualcomm MDM9635M LTE Cat. 6 Modem (vs. the MDM9625M found in the iPhone 6)
  • InvenSense MP67B 6-axis Gyroscope and Accelerometer Combo (also found in iPhone 6)
  • Bosch Sensortec 3P7 LA 3-axis Accelerometer (likely BMA280)
  • TriQuint TQF6405 Power Amplifier Module
  • Skyworks SKY77812 Power Amplifier Module
  • Avago AFEM-8030 Power Amplifier Module
  • 57A6CVI
  • Qualcomm QFE1100 Envelope Tracking IC
  • Toshiba THGBX5G7D2KLFXG 16 GB 19 nm NAND Flash
  • Universal Scientific Industrial 339S00043 Wi-Fi Module
  • NXP 66V10 NFC Controller (vs. 65V10 found in iPhone 6)
  • Apple/Dialog 338S00120 Power Management IC
  • Apple/Cirrus Logic 338S00105 Audio IC
  • Qualcomm PMD9635 Power Management IC
  • Skyworks SKY77357 Power Amplifier Module (likely an iteration of the SKY77354)
  • Murata 240 Front-End Module
  • Possibly a Bosch Sensortec barometric pressure sensor BMP280
  • RF Micro Devices RF5150 Antenna Switch
  • NXP 1610A3 (likely an iteration of the1610A1 found in the iPhone 5s and 5c)
  • Apple/Cirrus Logic 338S1285 Audio IC (likely an iteration of the 338S1202 audio codec found in the iPhone 5s)
  • Texas Instruments 65730AOP Power Management IC
  • Qualcomm WTR3925 Radio Frequency Transceiver

iFixit gave the iPhone 6s a repairability score of: 7 out of 10. Factors for that score included:

  • The display assembly continues to be the first component out, simplifying screen repairs.
  • The battery is straightforward to access. Removing it requires a proprietary pentalobe screwdriver and knowledge of the adhesive removal technique, but is not difficult.
  • The Touch ID cable is still tucked out of the way, but is paired to the logic board, complicating repairs.
  • The iPhone 6s still uses proprietary Pentalobe screws on the exterior, requiring a specialty screwdriver to remove.
