Our take on the Samsung Galaxy A15 5G 128GB 4GB RAM Blue Black Smartphone (AT&T) SM-A156U1/DS

The Galaxy A15 5G is Samsung's entry-level 5G phone. It pairs a 6.5-inch Super AMOLED screen with a MediaTek Dimensity 6100+ octa-core chip, 4GB of RAM and 128GB of storage, plus a 50MP main camera and a 5,000mAh battery with 25W charging. The AMOLED display is the standout at this tier, where many rivals still use LCD. It suits budget buyers who want a big, bright screen, long battery life and Samsung's update policy, but the 4GB of RAM and modest chipset make it a light-use phone rather than a gaming one.

Questions and answers

Is the Galaxy A15 5G good for gaming?
Only for light games. The Dimensity 6100+ and 4GB of RAM handle casual titles, but demanding 3D games run at low settings and can stutter.
Does the Galaxy A15 5G have a microSD slot?
Yes. Storage can be expanded with a microSD card, which matters because the phone ships with 128GB.
How does it compare with the Galaxy A25 5G?
The A25 5G has a faster Exynos chip, more RAM and an ultrawide camera. The A15 5G keeps the same AMOLED approach but is the cheaper, slower option.
Does it support 5G on AT&T?
This version is the AT&T model, so it is set up for AT&T's network. Check band support with your carrier before using it elsewhere.

No. The 5,000mAh battery is sealed inside the phone and charges over USB-C at up to 25W.
