The Samsung Galaxy Z Flip6 brings several key improvements over the Z Flip5. Some are pretty straightforward like using a 50MP sensor in the main camera. Others took some doing. For example, the 2024 model features a larger combined battery capacity of 4,000mAh, compared to the 3,700mAh of the Z Flip5.
It is split between two cells – the main one with 2,870mAh and a secondary cell with 1,130mAh capacity. The Z Flip5 battery was split into a 2,700mAh main and 1,000mAh secondary cells, so the 2024 model managed to pack more into each. You can see them in PBKreviews’ teardown video, here are some screen grabs from that:

Another major improvement this year is the addition of a vapor chamber for cooling the chipset. It’s a fairly large one – it is supposedly larger than the one inside the S24 Ultra. It’s still not large enough, though, in our review we saw terrible performance under sustained load (to be fair, flip foldables typically struggle with this, vapor chamber or not).

Interestingly, the Samsung Galaxy Z Flip6 received a slightly higher repairability score than the Z Flip5. The difference is in how easy it is to repair the screens. The addition of particle protection (part of the IP48 rating) could easily have made things tougher.
JerryRigEverything also made a video about the Galaxy Z Flip6, this one focused on a durability test. It puts the new particle protection to the test and tries (unsuccessfully) to bend the phone the wrong way. But perhaps the most interesting part of the video is the one that peels the display apart. The first layer is the plastic protector, then another layer (which might be the mysterious new Shear Thickening Fluid layer) and below that is the UTG. If you were wondering, yes, UTG does crack like regular glass, which is why it needs the extra protection.
