If you’re curious of what goes into the Xiaomi Mi 4, a couple of folks at the MIUI Forum had managed to give it a proper tear down treatment. The new flagship comes with a solid metallic frame and while the previous Mi 3 is still slimmer by 0.8mm, the curved back promises to offer a more comfortable grip that feels natural in the hands.
The Mi 4 back cover is removable and it is customisable with a range of wood, bamboo, textile, marble and leather textures but its battery isn’t user replaceable. From the tear down process, the 3,080mAh capacity unit is found to be sourced from Sony and its micro-USB port is seen to have 6 pins, which is a one extra than the standard 5-pin design. The 6-pin design is likely to support its rapid charging that claims to do 60% charger within 1 hour with its 9V 1.2A charger. As comparison, the Oppo Find 7 with VOOC Charging technology comes with a 7-pin micro-USB design. Since this isn’t from iFixit, there’s no repairability score for this one. From the photos, it looks easily dismantled with precision screw drivers and they have reported that each screws are labelled with tiny MI stickers which upon tampering would void its official warranty.

The Nokia X, which is Nokia’s affordable Android smart phone priced at RM399 has gotten its tear down treatment. Being a budget device, the Nokia X appears to have very few parts making manufacturing and repairs rather easy. There’s a total of about 13 removable components (without battery) and 11 screws.
However if you break the glass, it might be costly as the front cover and touch panel display are listed as a single assembly. To recap, the Nokia X comes with a 4″ WVGA display and runs on a dual-core 1GHz processor with 512MB RAM and 4GB of storage. It has a rather basic 3MP shooter without assisted flash and runs on Android 4.1.2 with Nokia’s custom skin. You can check out our hands-on with its bigger Nokia XL here.

Once again, the folks at iFixit has gotten the latest iPad mini with Retina display which goes through yet another tear down process. For a start, it is good to know that the LCD isn’t fused to the glass making replacement easier. Underneath the LCD panel lies its huge 6471mAh battery which is about 50% more than its previous non-Retina model. Fortunately the battery isn’t soldered as well but its held in place with adhesive.
Overall iFixit rated the iPad mini 2 out of 10 in repairability scores due to excessive use of glue and hidden screws which makes replacing a challenge. Even the lightning connector is permanently soldered to the logic board. You can check out the step by step tear down or watch the video after the break.
With any new devices, it is time for a Nexus 5 drop test from Android Authority. For the Nexus 5, they are doing it at a perfect venue over at Google’s Googleplex surrounded by the various Android statues.
Compared to the Nexus 4 drop test, the plastic back of the Nexus 5 appears to be more robust. However since it isn’t a single uni-body construction, the snap on back cover starts to open around the corners where it gets the most impact.

The folks at iFixit has gotten their hands on a Nexus 5 and it is time for another round of smart phone tear down. While the body construction uses plastic as opposed to a more premium glass on the Nexus 4, the new device is praised with a high repairability close.
The Nexus 5 uses plastic clips to attach its back cover while using just a little bit of adhesive to keep it securely in place. Most of its components including the motherboard and various modules such as headphone jack and speakers are easily removable thanks to its minimal use of glue. On the downside, the only complication is its 4.95″ Full HD screen which is fused together with its front glass.

The guys at iFixit has done it again with another round of tear down of the iPhone 5. While most might find the iPhone 5 design to be similar as the previous model, the assembly of the iPhone 5 is actually very different.
Instead of opening from the back to access the front, the iPhone 5 adopts a top down approach assembly. To remove the front glass, which is the more commonly replaced component, all you’ll need is a a pentalobe screwdriver and a suction cup to lift the glass. This is a remarkable improvement and definitely makes broken glass replacement fairly quick. According to iFixit, the iPhone 4S takes about 45 minutes to replace the front glass but it takes about 10-15 minutes to replace the glass on the iPhone 5.
Other discovery includes a slightly higher voltage battery at 3.8V (iPhone 4S: 3.7V) and it comes with 1,440mAh capacity. The durable iPhone 5 aluminium frame is surprisingly light, being only slightly heavier than the front glass.

The tear down looks easy with a couple of screws that’s colour coded. The inner back cover houses the NFC module that’s connected by a ribbon cable. The battery inside looks like a standard Sony Ericsson which is reported to be easily replaced.

The new iPad 3rd generation goes on sale today and has already gotten a tear down treatment by iFixit. One of them flew all the way to Melbourne and was the first in line to purchase it for the sake of dismantling.
They have gotten the 4G + WiFi version but unfortunately it doesn’t work on Telstra’s 4G Network. The 4G LTE support on the new iPad is limited to 700MHz and 2100MHz frequency but Telstra’s LTE network runs at 1800MHz. Despite that, it should be faster than normal 3G as it supports HSPA+ up to 42Mbps on telcos that support DC-HSPA. On the tear down process, the LCD and the huge new battery was reported to be easy to dismantle. However the front panel like the previous iPad 2 is still fused with the device, making it a challenge to remove.

The iPhone 4S has finally gotten its innards expose with iFixit professional tear down. Apart from the new processor, 8MP camera and dual CDMA/GSM support, we are able to find out what else is new on this model compared to the previous iPhone 4.
First is the RAM which was earlier said to be either 512MB or 1GB. From the tear down, it is finally confirmed that the iPhone 4S offers 512MB which is the same capacity as the previous model. This was identified from the marking on the A5 chip.
Another surprise is the battery which has a slightly higher capacity of 5.3Whr. This is 0.05Whr more than the original iPhone 4 which is rated at 5.25Whr. For those that are used to mAh battery capacity rating, that’s an extra 14mAh. The vibrator is using the one found on the CDMA version of the iPhone 4 which is reported to be quieter and softer than the previous version.

Before anyone could blend or break the Galaxy S II down to its components, Samsung has released an official tear down of the device. Unlike iFixit step by step dismantling, Samsung offers an overview of its components hidden under that
8.98.49mm thin body.
It shows you where the vital components are located as well as materials used in its construction. For example the back plate uses a 0.1mm thin Hyperskin material which features 3000 chain patterns to prevent scratches, fingerprints and slips.
