Galaxy Z Flip 4 shows internal changes in teardown video

A few days after being announced, the Samsung Galaxy Z Flip 4 underwent the first dismantling process, showing the differences in internal components compared to the previous generation. Despite presenting a very similar construction, the launch has noticeable improvements in aspects such as antennas for 5G connectivity, battery, heat dissipation structures and cameras.
- Galaxy S23 Ultra may repeat the predecessor’s design, but would have a 200 MP camera

Galaxy Z Flip 4 brings simple changes inside
The dismantling was carried out by the channel PBK Reviews and reinforces how the changes to the internal components of the Galaxy Z Flip 4 were simple compared to the predecessor, although they bring good improvements. Despite the collapsible construction, the opening process follows the mold of other smartphones by requiring heating the back covers and a tool to remove the glue.
Inside, the channel notes how the company has reorganized the positioning of some connectors, including those for the batteries, which have moved from the right to the left side. In addition, Samsung has implemented an additional antenna to capture the 5G mmWave signal — the pure version of the new high-frequency network, very sensitive to interference — now present near the hinge.
By removing the first components, it is also possible to notice the increase in the size of the main camera’s sensor, an important point to increase light capture. According to Samsung, the novelty would present significantly larger pixels, capable of absorbing up to 65% more light, thus presenting better HDR performance and improvements in night recordings.

The enlarged battery of the Galaxy Z Flip 4, divided into two cells, follows the bad practices seen in other Samsung phones of using permanent adhesive instead of easy-to-remove tapes, which makes it difficult to replace. Specialized stores or more advanced users who intend to change the cells will have to use isopropyl alcohol and apply force for removal.
Another interesting aspect is the motherboard and the cooling system: the South Korean giant chose to divide the region into two layers, employing graphite sheets on both sides and on the glass cover to dissipate the heat generated by the processor. In view of the observed, PBK Reviews gave an overall rating of 4 for ease of repair, with the battery’s permanent glue and flexible screen being the most complex points of the repair.
Galaxy Z Flip 4 stands out for processing and battery
One of Samsung’s main novelties for the end of the year, the Galaxy Z Flip 4 refines the predecessor’s formula, promising to deliver a complete and attractive experience for users who were still afraid of the limitations of foldables, especially processing and battery. The novelty comes equipped with Snapdragon 8 Plus Gen 1, 8 GB of RAM and up to 512 GB of storage, in addition to a 3,700 mAh battery, the same capacity as the standard Galaxy S22.

With straighter sides, thinner Aluminum Armor frames and a more compact hinge, the device maintains the look of its predecessor while adopting more modern features. The company also promises greater resistance, with unprecedented Gorilla Glass Victus Plus glass in the outer region and the new generation of ultra-thin glass in the flexible panel, and maintained the IPX8 water resistance certification, still seen only in the brand’s foldables.
Along with the Galaxy Z Fold 4 and the company’s new accessories, the Galaxy Z Flip 4 debuts in Brazil this Tuesday (23), in a special event that airs from noon in Brasília time.
