The Apple iPhone SE reviewed here uses an Apple A9 chipset (1.8 GHz, 2 cores) paired with roughly 2,013 MB of RAM, a 4" 1136x640 display and 16/64 GB storage options; it shipped with iOS 9.3 and a 12 MP rear camera. Its hardware footprint targets buyers who want a small, pocketable iPhone with the single-threaded responsiveness of Apple's A9-era silicon.

This review is grounded in public benchmark datasets and aggregated user submissions: Geekbench (single ~618 / multi ~937, Metal ~2,768), PassMark iOS averages (CPU Mark ~1,941, Memory Mark ~16,150, Disk Mark ~6,039, 3D Mark ~15,785) and UL Solutions 3DMark Wild Life results (score ~1,838, ~11 FPS, stability 66%). Where relevant I cite those measured numbers rather than anecdote.

High-level verdict: the SE is still a competent pocket phone for light apps and anyone who prioritizes a small screen and good single-core performance. Its worst aspects are constrained memory (≈2 GB), limited onboard storage (16/64 GB), and weak sustained GPU performance for gaming — 3DMark reports low frame rates (~10–11 FPS) and stability issues (66–72%), which translate to throttling and poor modern gaming performance.

CPU single-threaded speed remains competitive, multi-core and GPU lag

Geekbench results show a single-core score around 618 and multi-core around 937; the device reports an Apple A9 CPU at 1.8 GHz with 2 cores. PassMark lists an average CPU Mark of ~1,941, indicating the SE's per-thread responsiveness is still useful for everyday apps and web browsing.

GPU and sustained performance tell a different story: UL 3DMark Wild Life median scores are ~1,838 with graphics test frame rates of ~10–11 FPS and stability between 66% and 72%. Those figures mean games and prolonged 3D workloads will be limited by low frame rates and thermal/consistency issues.

Small 4" 1136×640 screen and compact chassis define the user experience

The iPhone SE uses a 4" 1136x640 display — its compact size is the defining attribute and remains attractive to buyers who prefer one-handed use. The pixel count and 4" panel are modest by modern standards and limit media immersion and dense web layouts compared with larger phones.

The compact build and classic iPhone proportions are practical, but the small screen inherently reduces the workspace for multitasking and modern apps designed for larger canvases.

Benchmarks show instability under sustained GPU load; battery results vary in public datasets

UL's Wild Life tests report stability of 66% (Wild Life) and 72% (Wild Life Unlimited), which suggests the SE down-clocks under sustained load; graphics test 1 produced ~11 FPS in one dataset and ~10 FPS in another. Those stability numbers are a quantifiable indicator of thermal throttling or inconsistent performance during extended 3D usage.

UL Solutions notes battery-life submissions in public benchmarks have a wide spread because they are taken under different user conditions; the dataset here does not provide a single controlled battery-life number, so battery experience should be judged cautiously and is likely variable depending on brightness and background activity.

Limited storage options and legacy OS origin constrain versatility

The model was offered with 16 GB and 64 GB storage configurations; PassMark Disk Mark averages ~6,039, which reflects the storage performance in submitted tests but does not mitigate low capacity for app, photo and OS growth over time.

The device originally shipped with iOS 9.3 (as listed in UL data) and PassMark's database shows 'Most Common OS: Unknown' for current submissions — a factual signal that software longevity and modern app compatibility are material concerns for buyers today.

12 MP rear camera delivers era-appropriate stills but lacks modern multi-camera features

The iPhone SE includes a single 12 MP rear camera (listed in UL Solutions data). For straightforward daylight photography this sensor remains competent, but benchmark and spec datasets do not show modern computational multi-lens features that newer phones provide.

Because the brief focuses on benchmark aggregates it doesn't include side-by-side image comparisons, but buyers should expect basic 12 MP performance rather than the advanced night, ultra-wide or telephoto imaging found on later iPhone models.

Pros & Cons

  • ✅ Compact 4" 1136x640 display — genuinely pocketable and easy one-handed use
  • ✅ Respectable single-core performance: Geekbench single-core ~618 supports snappy everyday app responsiveness
  • ✅ 12 MP rear camera suitable for straightforward daylight photos
  • ✅ PassMark Memory Mark ~16,150 and Disk Mark ~6,039 indicate solid memory/disk performance for its generation
  • ✅ Well-documented benchmark results (Geekbench, PassMark, UL) make performance expectations predictable
  • ❌ Only ~2,013 MB (2 GB) of RAM — limits multitasking and modern app memory demands
  • ❌ Storage stuck at 16 GB or 64 GB only — easily fills with apps and media
  • ❌ Weak sustained GPU performance: 3DMark Wild Life ~1,838 with ~10–11 FPS and stability 66–72%
  • ❌ Originally shipped with iOS 9.3 and 'Most Common OS: Unknown' in datasets — software longevity is a concern

How It Compares to the Competition

  • Apple iPhone 6s — Shares the A9 chipset lineage (similar era performance) but offers a larger 4.7" display — similar single-core responsiveness in a bigger form.
  • Samsung Galaxy A71 — Listed nearby in Geekbench rank data as a comparable-performance alternative; typically offers larger screens and more RAM for multitasking compared with the SE.
  • Xiaomi Redmi Note 7 Pro — Appears in Geekbench-comparable lists; generally provides more modern hardware (bigger display, more storage/RAM) for users who don't need an iOS environment.
  • Realme 7 — Another Android alternative appearing near the SE's benchmark band but with newer SoC and higher sustained GPU performance in its class.

Who Should Buy This & Who Should Skip It

Buy it if: Buy the iPhone SE if you prioritize a truly compact 4" iPhone and want strong single-core snappiness (Geekbench single ~618) for web browsing and light apps, and you can live with 2 GB RAM and 16/64 GB storage. It's a pragmatic choice for users who prefer a pocketable iOS device over modern multi-camera or gaming performance.

Skip it if: Skip this model if you need sustained 3D performance or modern gaming — UL 3DMark Wild Life shows ~10–11 FPS and stability of 66–72% — or if you routinely run many apps at once, need more than 2 GB RAM, or require large local storage and the latest OS longevity.
