Battery facts

Capacity 2700 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.

Display Quality

Confidence: medium
Score 28/100
Panel IPS LCD
Size 5.5"
Resolution HD (720 x 1280 pixels)
Display capability index 28/100
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 28/100
Sustained 16/100

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

Peak / overall 28/100
Sustained / thermal 16/100

SoC

MediaTek MT6580
specification high

GPU

Mali-400 MP
specification medium

RAM

2 GB
specification high

CPU

Quad core, 1.3 GHz, Cortex A7
specification medium

Peak silicon index (catalog model)

28/100
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)

16/100
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 35/100

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

Overall camera score 35/100
  • Rear camera setup 8 MP

    All rear lenses listed in the catalog.

  • Main lens 8 MP

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

  • Rear lens count 1 cameras
  • Front / selfie camera 2 MP
  • Optical stabilization (OIS) Not indicated in catalog

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

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 v6.0 (Marshmallow)

Operating system and skin listed for this phone.

specification
Android generation Android 6

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

70.57 %

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

Connectivity

Confidence: low
Score 82/100
Cellular

No

Wi-Fi

Yes, Wi-Fi 4 (802.11 b/g/n)

Bluetooth

Yes, v4.0

NFC

No

GPS

Yes with A-GPS

USB

microUSB 2.0

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 9/100
Weak Value
Why this score

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

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

9 /100
Poor deal Fair Great deal

Weak Value

What drives this value score

  • Current price 159.91 PKR
  • Configuration Evaluated configuration: 2 GB RAM at the current listed price.
  • Relevant peers 12
  • Peer price position Slightly above peer median
  • Capability vs peers Below typical peer capability
  • Premium justification Premium not justified by capability gains
  • Long-term support 29/100
  • Major strengths battery, connectivity
  • Major weaknesses display, performance, software support, camera
  • 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 battery and connectivity, weaker in display and performance, 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 Looking solid

Fresh ownership

Battery endurance starts in a healthy place. Runs Android v6.0 (Marshmallow) - confirm the brand update promise before year 3.

Year 2 Looking solid

Still strong

Battery endurance starts in a healthy place. Runs Android v6.0 (Marshmallow) - 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.
