In another packaging trick, Apple broke the iPhone X battery into two pieces to give it more flexibility fitting into the jigsaw puzzle of the handset.
Calling it a first for the iPhone, iFixit described the combined battery as 10.35 Wh (2,716 mAh at 3.81 V). It is larger than the 10.28-Wh version in the iPhone 8 Plus but smaller than the 12.71-Wh battery in the Samsung Galaxy Note 8, said iFixit.
“The dual-cell design is more of a space-utilization measure than a capacity-changing one,” said TechInsights, describing the subsystem in its model as a 5,432-mAh battery, “assuming they are in series.”
“There were no big surprises in semiconductors so far, most of the components are similar to what we saw in the iPhone 8 and 8 Plus,” said Yang of TechInsights.
The teardown did show the iPhone X still uses a Sony image sensor and a time-of-flight sensor from STMicroelectronics. In addition, STM supplied the IR camera in the new handset—a key component of its depth camera, Yang said.
Here’s a list of components that iFixit found in the CPU mainboard of its model:
- Apple APL1W72 A11 Bionic SoC layered over SK Hynix H9HKNNNDBMAUUR 3 GB LPDDR4x RAM
- Apple 338S00341-B1
- TI 78AVZ81
- NXP 1612A1 — likely an iteration of the 1610 tristar IC
- Apple 338S00248 audio codec
- Apple 338S00306 power management IC
Components that iFixit found on the modem board included:
TechInsights found on its model:
- Intel PMB9948 baseband processor
- Intel PMB6848 PMIC
- Murata Wi-Fi module
TechInsights will continue to de-cap and examine the chips in the iPhone X, a process which could take several days.
