The Samsung Galaxy Z Flip series has been the most affordable foldable device in the market and an impressive feat of visual aesthetics and performance by Samsung. The latest Z Fold 4 does not disappoint and improves on most aspects from its predecessor. The 6.7 inches main display is a 120Hz Foldable Dynamic AMOLED 2x display that is bright to use even on sunny days. With foldable devices, the durability of the display is paramount, and Samsung boasted having up to 45% better durability for the Flip 4 display due to stronger ultra-thin glass and better display structure. The cover display albeit small at 1.9" has improved functionalities and widgets that you can enable on the display as well as access your Samsung Wallet. Similar to the flagship foldable Z Fold 4, the Flip 4 has a Qualcomm Snapdragon 8Gen1 processor that packs plenty of punch for the small foldable. It has also 8GB of RAM and either 128GB, 256GB or 512GB of storage space. Samsung has sped up the charging for the Flip 4 and it offers now 25W fast charging. They have also improved the battery capacity to 3700mAh so the battery should, in theory, last as much as 10% longer than the Z Flip 3 which already could easily get by a full day of active use. When compared to the Z Flip 3, the Z Flip 4 has a better battery, improved camera, more power, faster charging, better camera sensor and a slightly slimmed down form factor.
