Quick answer
Yes, a Samsung Galaxy S5 battery case like the Naztech 3200mAh flip model still works reliably in 2026. It nearly doubles your phone's run time and adds solid protection, though you lose some slimness and the case uses an older micro-USB port.
What to expect from a Galaxy S5 battery case in 2026
The Samsung Galaxy S5 launched over a decade ago, but many people still use it as a backup phone, media player, or travel device. A dedicated battery case solves the main weakness of aging lithium-ion batteries: reduced capacity. Instead of swapping batteries or hunting for a wall outlet, the case provides a seamless power boost.
The Naztech 3200mAh Power Case is a flip-style design that wraps around the phone. It uses the S5's own charging port, so there is no guesswork about compatibility. The trade-off is that the case adds noticeable bulk and uses micro-USB, not USB-C. If you are used to modern charging standards, you will need to keep a micro-USB cable handy.
Is the Naztech case still a good buy?
For anyone who already owns a Galaxy S5 and wants to extend its usefulness, the Naztech case is a practical accessory. It is built to last, with a sturdy frame that protects the phone during drops. The built-in battery is rated to nearly double your talk time, music playback, and video watching.
The main limitation is that the case does not support fast charging or wireless charging. It also covers the phone's headphone jack and speaker grille, so you will rely on Bluetooth audio. If those trade-offs are acceptable, the case remains a cost-effective way to keep an S5 running all day.
Frequently asked questions
Does the Naztech case fit with a screen protector?
Yes, the flip-style design leaves the screen fully accessible. Most standard screen protectors will fit without interference. Thick glass protectors may add a tiny gap, but the case still closes securely.
Will the case charge the phone while I use it?
Yes. The Naztech case passes power through to the phone's internal battery. You can charge the case itself via micro-USB while the phone is inside, and the phone will charge first before the case battery depletes. For best battery health, avoid leaving the case plugged in 24/7 once the phone is full.
Does the case interfere with the S5's water resistance?
The Galaxy S5 has an IP67 rating with the back cover and USB port flap sealed. The Naztech case replaces the standard back cover and covers the USB port, so the original water resistance is no longer guaranteed. The case itself is not waterproof. Treat the phone as non-water-resistant when using the case.
Can I still use the S5's camera and buttons?
Yes. The case has precise cutouts for the rear camera, flash, volume rocker, and power button. The flip cover does not obstruct the lens. The home button and fingerprint sensor remain accessible.
How do I know when the case battery is low?
The Naztech case includes a small LED indicator on the back. A steady blue light means the case battery is charged; a blinking or red light signals low power. Press the button on the back to check the status at any time. Charge the case overnight if you plan a heavy-use day.
