The Galaxy Z Fold 7 from Samsung brings a thinner, lighter design and the promise of premium multitasking in a pocketable form factor. While the hardware and software experience have taken a noticeable leap forward, our in-house testing shows that battery life and charging remain virtually unchanged from the previous model.
Despite the presence of the new Snapdragon 8 Elite chip and Samsung’s AI-powered software optimizations, the Fold 7 delivers no meaningful improvement in real-world battery life. And while its charging speeds are still serviceable, they fall far behind the competition in the fast-charging race.
Does the Galaxy Z Fold have better battery life?
No, it does not. Now that we have carried out our extensive battery life tests, we can confirm that the battery life on the Galaxy Z Fold 7 is nearly identical to that of the Galaxy Z Fold 6.
That was to be expected given that the battery capacity has remained the same 4,400 mAh, but we were hoping for at least 30 minutes more of estimated battery life as a result of Galaxy AI and the Snapdragon 8 Elite. Alas, that is not the case.
Galaxy Z Fold 7 PhoneArena Battery and Charging Test Results:
Among its main competitors, we estimated the Galaxy Z Fold 7 to have the shortest battery life during mixed usage, coming in at around 5 hours and 30 minutes — roughly the same as its predecessor. It actually performed better in our Web Browsing and Video Streaming tests, but its overall score was dragged down by a noticeable drop in the Gaming test. That dip is likely due to the Snapdragon 8 Elite’s more demanding GPU, which requires more power to sustain its higher graphical performance.
Galaxy Z Fold 7 charging speed
Despite being a 2025 flagship, the Galaxy Z Fold 7 retains the same charging specs as the last several Fold generations:
It’s perfectly serviceable, but well behind foldable competitors, some of which push 66W–100W charging speeds.
- 25W wired charging
- 15W wireless charging (Fast Wireless Charging 2.0)
- 4.5W reverse wireless charging (Wireless PowerShare)
It’s perfectly serviceable, but well behind foldable competitors, some of which push 66W–100W charging speeds.
Wireless charging is still capped at 15W, and you’ll only get those speeds using Samsung’s official Fast Wireless Charger Stand or Duo. Third-party Qi chargers may top out around 10W.
During our Z Fold 6 tests, wireless charging to 100% took over 3 hours, and we expect similar results with the Z Fold 7 unless Samsung has quietly improved thermals or charging curves.
Does the Galaxy Z Fold 7 have reverse wireless charging?
Yes — Wireless PowerShare is supported on the Z Fold 7.
You’ll are able to:
Samsung hasn’t introduced improvements to this feature, so the use case remains occasional convenience rather than daily charging.
You’ll are able to:
- Charge Galaxy Buds, a Galaxy Watch, or another phone by placing it on the Fold’s back
- Output remains limited to 4.5W, suitable only for quick top-ups

What charger does the Galaxy Z Fold 7 use?
As always, no charger is included in the box. You’ll need:
Samsung’s adherence to USB PD PPS means you can safely use reputable third-party chargers from Anker, Ugreen, Baseus, or similar brands.
This also makes the Fold 7 friendlier than many competing brands (like Xiaomi or Motorola), which fall back to slower charging unless you use a proprietary charger and cable combo.
- A USB Power Delivery PPS charger rated at 25W or higher
- A USB-C to USB-C cable rated for 3A
