Intex Aqua Zenith Full Specifications, Price and Review
The Intex Aqua Zenith is a well-rounded budget dual SIM 4G smartphone from Intex Technologies, launched in May 2017. Unlike several other Intex models from the same period, the Aqua Zenith stands apart with a critical advantage — it supports full 3G on both SIM slots, making it reliable across India regardless of 4G signal availability. It also includes USB OTG, 128GB expandable storage, a complete sensor suite with proximity, accelerometer and ambient light sensor, and runs Android 7.0 Nougat. With a slim 9.55mm profile weighing 143.2 grams and available in the premium-looking Classy Gold and Black finishes, the Aqua Zenith is one of the more feature-complete phones in Intex's 2017 budget lineup. This guide covers the complete Intex Aqua Zenith specifications, standout features and buying advice.
How the Intex Aqua Zenith Compares to Other Intex 2017 Phones
Buyers comparing the Aqua Zenith against other Intex models from 2017 will notice one immediately important difference — 3G support. Models like the Aqua Strong 5.1 Plus, Aqua Crystal Plus and Aqua 4G Mini all lack 3G entirely, falling back to 2G when 4G is unavailable. The Aqua Zenith supports 2G, 3G and 4G on both SIM slots, making it significantly more reliable in areas with patchy 4G coverage. Combined with its USB OTG support and full sensor set including accelerometer and proximity sensor, the Zenith offers a meaningfully more complete feature set than its siblings at a comparable price.

Intex Aqua Zenith vs Aqua Crystal Plus — Key Differences
Buyers choosing between the Aqua Zenith and the Aqua Crystal Plus — both launched in May 2017 at similar prices — should weigh these key differences:
| Feature | Aqua Zenith | Aqua Crystal Plus |
|---|---|---|
| 3G Support | Yes — both slots | No |

Intex Aqua Zenith USB OTG — What You Can Connect
The Intex Aqua Zenith supports USB OTG (On-The-Go), allowing it to act as a USB host with an OTG adapter. Practical uses include connecting:
- USB pen drives — access and transfer files without a PC
- USB keyboards — faster typing for long documents and emails
- USB mice — navigate the phone without touching the screen
- SD card readers — read camera SD cards directly on the phone
- USB game controllers — play compatible Android games with physical controls
Intex Aqua Zenith Battery and Design
The 2000mAh non-removable battery is modest for a 5-inch phone but the FWVGA resolution and entry-level processor keep power consumption low. Expect around 8–10 hours of moderate usage covering calls, messaging and social media. The 9.55mm thin body at 143.2 grams is comfortable to hold one-handed and sits slim in a pocket. The Classy Gold colour option in particular gives the Zenith a more premium appearance than its entry-level price suggests — a point of differentiation against the plain colour options on competing budget phones.
Is the Intex Aqua Zenith Worth Buying in 2025?
The Intex Aqua Zenith was a sensible mid-tier Intex choice in 2017 — particularly for buyers in areas with inconsistent 4G coverage who needed 3G as a safety net. It covered more real-world usage scenarios than the Aqua Crystal Plus thanks to full 3G support and an accelerometer for screen rotation. In 2025 however, Android 7.0 Nougat is long unsupported and 1GB RAM is insufficient for modern app requirements. For a current budget alternative with equivalent connectivity reliability and current Android, consider the Nokia C32, Lava Yuva 3 Pro or Redmi A3 — all offering full 4G with VoLTE, current Android and significantly improved performance.
