Battery life is one of the biggest complaints among smartphone users, and Realme seems to have an answer. The new Realme 15x 5G is coming to India with a massive 7,000mAh battery, dual 50MP cameras, and a robust durability rating that’s rare in this price range. With a starting price of under ₹20,000, Realme is touting this phone as a great all-day companion. But does it really live up to expectations? Let’s take a closer look.
Realme 15x 5G Design & durability
Realme built the 15x with durability in mind: the phone carries IP69 (and IP68) dust/water resistance and even MIL-STD-810H (military-grade) shock resistance, so it’s clearly aimed at people who want a tougher daily driver rather than an ultra-fragile glass slab. The chassis is reasonably slim for a giant battery phone, and Realme advertises “party dress” inspired colour finishes for a bit of personality.
Realme 15x 5G: Display big, smooth and bright
The Realme 15x sports a 6.8-inch IPS LCD with a 144Hz refresh rate and an HD+ resolution (1570 × 720). Realme rates the display as “ultra bright” with peak brightness figures aimed at outdoor legibility, positioned around 1,200 nits in practical peak mode.
That means scrolling and gaming feel very smooth thanks to 144Hz, but pixel density won’t match Full HD phones — a tradeoff Realme made to balance cost and battery life.

Realme 15x 5G Performance
MediaTek Dimensity 6300 (6nm)
It features the MediaTek Dimensity 6300 (6nm) chipset – an efficient mid-range 5G SoC designed for everyday tasks, social media, and moderate gaming.
The phone comes with 6GB or 8GB of LPDDR4X RAM options and uses Realme’s Dynamic RAM Expansion technology for additional memory.
Storage options include 128GB and 256GB (UFS 2.2), and you also get microSD card expansion via a hybrid tray. This configuration is suitable for most users who prioritize battery and price over raw benchmark scores.
Realme 15x 5G Cameras: 50MP front and rear
One of the main changes is the camera hardware: a 50MP Sony sensor (said to be the Sony IMX852) on the rear and a 50MP front camera for selfies—a notable step up from many budget phones that cut back on selfie optics.
Expect good daytime photos and social media-ready selfies; low-light performance will largely depend on software processing and sensor aperture, so don’t expect flagship-level night magic, but Realme’s AI camera features could prove helpful.

Realme 15x 5G Battery & charging
This is the phone’s strongest aspect: the 7,000mAh “Titan” battery, which Realme claims can last for about two days of heavy use thanks to its Smart Power Saving Engine and long-lasting stats like hours of YouTube viewing and extended call times.
Realme pairs this massive battery with claims of 60W fast charging (Boost Charge mode), reverse charging, and quick top-ups (marketing also mentions “50% charge while showering” and quick-use top-ups in no time).
This combo means you get long battery life along with decent charging speeds when needed.
Realme 15x 5G Software & extras
The phone comes with Realme UI 6.0 based on Android 15, and Realme has promised some operating system upgrades (see official policy for the exact years promised to Indian buyers).
Other features include a side-mounted fingerprint sensor, a stereo-style speaker setup (advertised as “ultra-linear” with 400% volume boost marketing), 5G band support, and reverse charging.
If you prefer minimal bloat, Realme UI has become cleaner than recent versions, but expect some preinstalled apps.

Realme 15x 5G Price, availability & variants
Realme has priced the 15x very competitively in India: the 6GB + 128GB model is priced at around ₹16,999, the 8GB + 128GB at around ₹17,999, and the 8GB + 256GB at around ₹19,999 (launch offers and exchange discounts are common during the first sale).
It will be available through Flipkart, Realme stores, and major retail partners starting October 1, 2025 (launch day offers were listed on official channels). If you want a big battery for under ₹20,000, this phone is perfect.
Who should buy the Realme 15x 5G?
You want excellent battery life in a phone with a budget of ₹15,000-20,000.
You prioritize long screen time for social apps, videos, and light gaming.
You like the idea of better-than-average selfie and rear cameras in this price range.
Who should not buy the Realme 15x 5G?
You demand a Full HD display (that’s HD+), or you need top-tier gaming performance – some competitors trade battery for higher pixel density or stronger SoCs.
Verdict:
The Realme 15x 5G is clearly an affordable option: its massive 7,000mAh battery, 60W charging,
50MP front and rear cameras, and robust certifications make it an attractive daily driver for users who hate daily charging and want a durable handset that can take good photos.
Compromises like the HD+ display and mid-range Dimensity 6300 chip are deliberate to keep the price low and battery life high. If these match your priorities, the Realme 15x is worth considering.
