Battery facts

Capacity 4100 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 32/100
Panel IPS LCD
Size 5.5"
Resolution Full HD (1080 x 1920 pixels)
Display capability index 32/100
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 55/100
Sustained 39/100

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

Peak / overall 55/100
Sustained / thermal 39/100

SoC

Qualcomm Snapdragon 625 MSM8953
specification high

GPU

Adreno 506
specification medium

RAM

3 GB
specification high

CPU

Octa core, 2 GHz, Cortex A53
specification medium

Peak silicon index (catalog model)

55/100
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)

39/100
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 50/100

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

Overall camera score 50/100
  • Rear camera setup 13 MP + 8 MP

    All rear lenses listed in the catalog.

  • Main lens 13 MP

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

  • Secondary rear lens 8 MP
  • Rear lens count 2 cameras
  • Front / selfie camera 8 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 v8.0 (Oreo)

Operating system and skin listed for this phone.

specification
Android generation Android 8

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.

Connectivity

Confidence: low
Score 82/100
Cellular

4G

Wi-Fi

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

Bluetooth

Yes, v4.1

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.

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 v8.0 (Oreo) - confirm the brand update promise before year 3.

Year 2 Looking solid

Still strong

Battery endurance starts in a healthy place. Runs Android v8.0 (Oreo) - 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.

Evidence used

Capacity 4100 mAh
OS / UI Android v8.0 (Oreo)
Android generation Android 8
How this was calculated
  • No fabricated total cost of ownership or invented repair/battery-replacement prices.
  • Factual long-term factors only.

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.
