NEWDERY Samsung Galaxy S25 Plus Battery Case 10000mAh - All-day Power

In this review the NEWDERY battery case for the Samsung Galaxy S25 Plus targets users who need reliable, on-the-go power without giving up native phone functions. The single biggest reason to buy is the built-in 10000mAh battery with USB-C two-way fast charging, which lets the case both charge the phone and act as a 20W power bank for other devices while showing exact charge on an LED display. It is especially useful for travelers and long workdays where access to outlets is limited.

Key Features

• Two-way USB-C fast charging: The case supports 20W output and 18W input so the phone and the case recharge quickly and the case can charge other USB-C devices directly.
• 10000mAh capacity: A high-capacity internal battery provides extended runtime to keep a Galaxy S25 Plus running through a full day of heavy use.
• Upgraded wireless charging: The case supports charging the phone wirelessly and itself can be recharged on a wireless charger, reducing wear on the phone's port.
• LED display: A digital screen shows the remaining battery level precisely so there are no surprises about available power.
• Retention of original phone functions: Data sync, Android Auto and wired headset support remain functional with the case installed for seamless daily use.
• Protective hard-shell design: Raised sides and a durable shell shield the phone from drops, scratches and everyday wear while charging capability is preserved.

Who It's For

The NEWDERY S25 Plus battery case is best for commuters, frequent flyers and people who routinely spend long hours away from chargers and need a dependable backup that keeps full phone functionality. Its ease of use and LED readout make it practical for professionals who prefer predictable battery behavior and quick top-ups with 20W output.

Those who should look elsewhere include users who prioritize the thinnest possible case or the lightest carry: a 10000mAh integrated pack inevitably adds weight and bulk. Also, anyone using a different phone model should not buy this case because it is designed specifically for the Galaxy S25 Plus 6.7in model.

Pros & Cons

Pros

• Maintains data transfer and Android Auto functionality while providing extra battery life.
• Two-way USB-C charging and 20W output allow the case to charge other devices quickly.

Cons

• Added bulk and weight compared with a standard slim case, which some users note when carrying it all day.
• Charging speed reports are mixed among users, so real-world throughput may vary by cable and charger used.
