Battery facts

Capacity 4300 mAh
How this was calculated
  • Battery life is never scored from raw mAh alone - mixed-use uses usable Wh and calendar average power (smartphones ~1-2 days; basic phones can last several days).
  • Usage modes (standby, calls, video, gaming, etc.) show measured catalog values when available; otherwise Product Lab estimates.
  • Scenario hours are continuous-use estimates for that activity; mixed daily use is calendar endurance.

Charging Experience

Confidence: medium
Score 55/100
Wired charging power 30 W specification
Charging capability index 55/100 estimated
How this was calculated
  • Charging duration is never calculated as Capacity / Charger Wattage.
  • Capability score uses wattage bands only - charge minutes stay hidden without measured times.

Display Quality

Confidence: medium
Score 44/100
Panel AMOLED
Size 5.9"
Resolution 1080 x 2400 pixels
Display capability index 44/100
How this was calculated
  • Display score uses panel tech, refresh curve, brightness, density, and HDR â€" not refresh alone.

Sustained Performance & Thermals

Confidence: medium
Score 50/100
Sustained 32/100

Peak = short bursts of speed. Sustained = speed that lasts when the phone heats up.

Peak / overall 50/100
Sustained / thermal 32/100

SoC

Qualcomm Snapdragon 8 Plus Gen 1
specification high

GPU

Adreno 730
specification medium

RAM

8 GB

Storage

128 GB

CPU

Octa core (3.2 GHz, Single core, Cortex X2 + 2.75 GHz, Tri core, Cortex A710 + 2 GHz, Quad core, Cortex A510)
specification medium

Peak silicon index (catalog model)

50/100
estimated medium

How strong the chip looks for everyday apps, multitasking, and games - from catalog silicon tier, not a lab stress test.

Sustained thermal index (catalog model)

32/100
estimated medium

How well performance holds when the phone gets warm during longer sessions.

How this was calculated
  • Peak and sustained remain separate; sustained uses thermal retention by silicon tier when lab throttling data is absent.

Camera Quality

Confidence: medium
Score 74/100

Think of this as overall photo/video usefulness - megapixels alone do not make a great camera.

Overall camera score 74/100
  • Rear camera setup 50 MP + 12 MP

    All rear lenses listed in the catalog.

  • Main lens 50 MP

    Primary rear camera resolution (MP is only one quality factor).

  • Secondary rear lens 12 MP
  • Rear lens count 2 cameras
  • Front / selfie camera 12 MP
  • Optical stabilization (OIS) Not indicated in catalog

    OIS helps reduce blur in photos and video when your hands move.

  • Video 7680x4320 @ 24 fps3840x2160 @ 30 fps
How this was calculated
  • Megapixels alone do not dominate â€" architecture, stabilization, and video pipeline are weighted.
  • Estimated capability index used when no verified lab IQ measurement exists.

Software & Security Longevity

Confidence: low

Longer software support means safer apps and newer features for more years - important if you keep phones 3-4 years.

Update runway Not scored yet

No published support end-date in catalog, so we do not invent a longevity score.

OS / UI Android v12

Operating system and skin listed for this phone.

specification
Android generation Android 12

Newer generations usually start with a longer update runway - only brand promises confirm how long.

specification
Brand update promise Not published in catalog

We do not invent OS/security year promises. Ask the brand or wait for official policy.

specification
How this was calculated
  • No generic Android/iOS lifespan assumed.
  • Numeric software score hidden without support end/remaining data.

Durability & Repairability

Confidence: low
Frame

84.24 %

How this was calculated
  • No durability score from materials alone without enough evidence.

Connectivity

Confidence: low
Score 82/100
Cellular

Connectivity richness index

82/100

How this was calculated
  • Global capability facts only â€" no carrier compatibility claims without data.
  • Richness index counts verified radios/features, not network quality.

Audio Quality

Confidence: low
Speakers Yes
Audio tech 3.5 mm
How this was calculated
  • Hardware features are separate from measured audio quality.

Value for Money

Confidence: medium
Score 5/100
Weak Value
Why this score

Weak Value because it is its higher price is not fully justified by capability versus peers, strong in connectivity, weaker in battery and software support, software longevity is limited relative to a 7-year reference.

In plain words: weak value at this price versus similar phones (Weak Value).

Poor deal Fair Great deal

Weak Value

What drives this value score

  • Current price 767.43 PKR
  • Configuration Evaluated configuration: 8 GB RAM / 128 GB storage at the current listed price.
  • Relevant peers 11
  • Peer price position Meaningfully above peer median
  • Capability vs peers Below typical peer capability
  • Premium justification Premium not justified by capability gains
  • Long-term support 43/100
  • Major strengths connectivity
  • Major weaknesses battery, software support, display, performance
  • Value verdict Weak Value
  • Confidence Medium
How this was calculated
  • Weak Value because it is its higher price is not fully justified by capability versus peers, strong in connectivity, weaker in battery and software support, software longevity is limited relative to a 7-year reference.
  • Value is peer-relative capability vs price positioning with premium justification — never Score÷Price.
  • Diminishing returns applied to capability utility so mid-range gains matter more than top-end points.
  • Verified weaknesses reduce value; missing data does not.

3-4 Year Ownership / Long-Term Value

Confidence: low

A simple year-by-year ownership outlook based on battery, software, and durability evidence — not a guaranteed prediction.

Year 1 Mixed

Fresh ownership

Battery is only average - plan charging habits carefully. Runs Android v12 - confirm the brand update promise before year 3.

Year 2 Mixed

Still strong

Battery is only average - plan charging habits carefully. Runs Android v12 - confirm the brand update promise before year 3.

Year 3 Plan ahead

Watch the weak spots

Expect noticeable battery wear for heavy users by year 3. Brand update years are not clearly published - verify before keeping long-term.

Year 4 Plan ahead

Keep-or-replace year

Expect noticeable battery wear for heavy users by year 4. Brand update years are not clearly published - verify before keeping long-term.

Method notes

  • Detail page uses catalog features plus Product Lab multi-factor models (v2).
  • Missing categories are omitted (never shown as 0/100).
  • Charging duration is never fabricated from charger wattage; wattage yields capability only.
  • Value for Money uses peer-relative capability and premium justification â€" never Score÷Price.
  • Estimated indexes are not third-party lab certificates.
