Samsung’s Galaxy Z Fold 7, set to launch on July 9, 2025, retains the same 4,400mAh battery as its predecessor, disappointing fans hoping for a capacity boost. Charging speeds remain capped at 25W, lagging behind competitors. Despite a slim design and improved battery life of up to 40 hours, the foldable’s specs fail to match rivals like Honor Magic V5.
Samsung Galaxy Z Fold 7 Battery and Charging: A Missed Opportunity?
Battery Capacity Stagnates at 4,400mAh
Leaked specifications confirm the Galaxy Z Fold 7 will feature a 4,400mAh battery, identical to the Galaxy Z Fold 6. The actual rated capacity is slightly lower at 4,272mAh, as revealed by European Product Registry for Energy Labelling (EPREL) documents. While Samsung markets the battery as sufficient for up to 40 hours and 28 minutes of usage per charge, this is notably smaller than competitors like the Honor Magic V5 (5,820mAh globally) and Oppo Find N5 (5,600mAh).
Charging Speeds Remain Unchanged
The Galaxy Z Fold 7 is expected to support 25W wired charging, a speed unchanged from the previous model. This is significantly slower than rivals offering 50W or higher, such as the Vivo X Fold 5. Wireless charging details are scarce, but leaks suggest compatibility with Qi2 and MagSafe via official cases, potentially enhancing convenience but not speed.
Battery Endurance and Longevity
According to EPREL labels, the Z Fold 7’s battery retains 80% of its capacity after 2,000 charge cycles, indicating strong longevity. Samsung’s optimizations may stretch the 4,400mAh battery to deliver up to 24 hours of video playback, but heavy tasks like video editing or gaming could drain it faster, especially with the power-hungry Snapdragon 8 Elite chipset.
Comparison with Galaxy Z Flip 7
The Galaxy Z Flip 7, launching alongside the Fold 7, gets a battery boost to 4,300mAh (rated at 4,174mAh), up from 4,000mAh in the Flip 6. This brings its capacity close to the Fold 7, despite the Flip’s smaller form factor. The Flip 7 is rated for up to 42 hours and 4 minutes of usage, slightly outperforming the Fold 7 in endurance.
User Sentiment and Market Impact
Posts on X reflect user disappointment, with some arguing the Fold 7’s 4,400mAh battery is “unacceptable” for its size, especially when the smaller Flip 7 is only 100mAh behind. Analysts suggest Samsung’s focus on a thinner 8.9mm design may have limited battery upgrades, but this risks alienating power users seeking flagship-level performance.
Competitive Landscape
Samsung’s foldables face stiff competition from brands like Honor, Vivo, and Oppo, which offer larger batteries and higher IP ratings (e.g., IP59 on Vivo X Fold 5). The Fold 7’s IP48 rating, unchanged from last year, offers moderate dust and water resistance but falls short of the IP68 standard seen in non-foldable flagships.
