The S-series is better. The question is whether it is better in ways you will use. For a large share of buyers the upper A-series covers everything they actually do, and the difference funds a substantially cheaper contract.

Where the real gaps are

Area Gap Who notices
Low-light photography Large Anyone photographing indoors or at night
Telephoto zoom Large — A-series has no true equivalent Anyone shooting distant subjects
Sustained performance Moderate Gaming, heavy multitasking
Display quality Small — upper A-series is AMOLED too Few people in normal use
Everyday speed Small Almost nobody
Battery life Often favours A-series Heavy users

The first two are the honest case for the S-series. The rest have narrowed to the point where the premium is hard to justify on them alone.

What the A-series has that the S-series does not

The storage point matters more than it sounds. On the S-series you must buy the capacity up front; on much of the A-series you can add a card later for a fraction of the cost.

Frequently asked questions

Is the S-series worth the extra?

Only for low-light photography, telephoto zoom or sustained heavy performance. Otherwise the upper A-series covers the same ground.

Is the A-series display worse?

The upper A-series uses AMOLED at high refresh rates, so the gap is small. Lower A-series models differ more.

Do A-series phones take a memory card?

Many do; the S-series generally does not.

Which lasts longer on battery?

Several A-series models have larger batteries than their S-series counterparts.
