Nintendo Switch Lite is currently on the market. Its compact body and fairly good battery life have won the favor of many handheld parties. The famous electronic equipment disassembly website iFixit brought us the disassembly process of this new machine, and let us take a look at the internal hardware design of this "handheld version" Switch .
Nintendo Switch Lite Basic information:
- custom NVIDIA Tegra X1 chip
- comes with a 5.5-inch LCD touch screen, resolution 1280*720
- built-in storage 32GB, up to 2TB micro SD card expansion , supports microSDHC and microSDXC types.
- 802.11 a/b/g/n/ac Wi-Fi support, Bluetooth 4.1, NFC, USB Type-C charging port, 3.5mm headphone jack
- built-in accelerometer and gyroscope
- 3 ~ 7 hours gaming Lithium-ion battery for battery life
- Non-removable handle.
Let's take a look at the sexy X-ray scans before we start dismantling. The handle part of
is indeed inseparable and requires traditional disassembly. The arrow keys have been replaced by Nintendo's traditional style, and are no longer four-key separation. The infrared capabilities of the original Joy-Con were chopped off on the Lite, and the speakers were moved from the front to the bottom. The Lite also lacks the stand, which means this is the most aerodynamic Switch (mistaken).
The fuselage uses a relatively rare screw type, which requires a special screwdriver to remove.
After removing the shell, there is still a shell inside, continue to dismantle. After disassembly, you will see that the SD card reader is detachable from the old version of the Switch. Now it has been soldered on the motherboard .
This is the internal circuit comparison of the new and old Switch. The most obvious is that the battery is no longer upside down.
Several key changes: the battery is smaller; the heat pipe is thinner; the headphone jack is completely modular, and the old version was soldered on the circuit board. Pull the battery out firmly, there is a large piece of adhesive on the bottom like a thick paper towel.
Switch Lite uses a 13.6 Wh battery, the original is 16 Wh. Although the battery is smaller, according to official data, the Switch Lite's battery life is still longer than the original.
More efficient hardware not only increases battery life, but also reduces heat generation. The improvement of NVIDIA's Tegra X1 chip technology has made the cooling fan of the Switch Lite smaller. In normal use, there is no need to worry about the core overheating and frequency reduction, because it cannot be connected to a TV, so it always outputs 720P images, and the computational load will not be so high.
Another small change is that the LR two trigger keys have been changed from the design of direct contact with the PCB board to the membrane type keys, which can provide more comfortable key travel in addition to some key protection. The
speaker is the same as the original Switch, but the casing is different.
Take out the Lite's handle part of the circuit board, and we can get the recently controversial Switch joystick part.
At first glance, the Lite's joystick looks very similar to this year's new version of the Switch, but the edge design near the buckle is slightly different, and the lid is easier to open.
Lite and the new version of Switch's joystick are not much different,It's just that the key part is thinner, and the metal slider looks a little wider. Whether it will continue to cause stick drift issues remains to be seen. The joystick in the picture corresponds to Lite, and the bottom corresponds to the normal version of Switch.
Motherboard removed. An obvious change is that the flash memory chip is no longer a modular design, but is directly soldered to the motherboard.

The original Switch adopts ordinary screen technology,More cost-effective and easy to maintain. The Lite's screen fits more compactly.
