Realme C100x Launched in India With 8,000mAh Battery and 45W Charging

Realme launched the C100x in India on July 16, bringing an 8,000mAh battery and 45W SUPERVOOC fast charging to the sub-Rs 15,000 price segment. The phone is available in one memory configuration (4GB/64GB) at a special launch price of Rs 14,499 through July 20, after which it reverts to its listed price of Rs 14,999.

The C100x is a 4G-only device built around the Unisoc T7250 chipset, positioning it as the most affordable entry in Realme’s current Indian lineup. Sales are live on Flipkart, Realme’s official website, and select offline retailers across the country.

Confirmed Specifications

At its core, the C100x uses the Unisoc T7250, a 12nm octa-core chip, with a Mali-G57 MP1 handling graphics. The phone ships with 4GB LPDDR4X RAM (expandable to 12GB through virtual allocation) and 64GB of internal storage on an eMMC 5.1 module. A dedicated microSD slot supports expansion up to 2TB.

Its 6.8-inch IPS LCD panel runs at HD+ resolution (720 x 1,570 pixels) with a 120Hz refresh rate and peaks at 900 nits brightness. The touch layer samples at 240Hz for faster input recognition. Realme has included a Rain Touch mode that keeps the screen responsive with wet or oily fingers.

Other hardware details:

Battery: 8,000mAh with 45W SUPERVOOC, 6W reverse wired charging

The phone also features Pulse Light, a circular LED ring on the rear panel that supports nine colors and five glowing modes. It activates during calls, messages, and charging.

What the India Model Gets Differently

One detail most coverage has skipped is that the Indian variant of the C100x differs from its global counterpart in at least two ways. The India model uses Panda@MN228 glass for display protection, while versions sold in other markets ship with ArmorShell glass. Panda Glass is manufactured by Tunghsu Group’s subsidiary and is a domestic Chinese alternative to Corning’s Gorilla Glass, but independent durability comparisons between MN228 and ArmorShell remain limited.

The Indian version also carries the larger 8,000mAh battery, while some global variants ship with a 7,500mAh cell. Realme has not explained the regional battery sizing difference publicly.

How the C100x Fits Against the Narzo 100x 5G

Realme launched the Narzo 100x 5G just one day before the C100x, on July 15. Both phones share an 8,000mAh battery with 45W charging, but the similarities largely end there.

The Narzo 100x 5G starts at Rs 20,999 for its 4GB/128GB base model, runs on the MediaTek Dimensity 6300 (a 6nm 5G chip), and offers a 144Hz display with 1,200 nits brightness. Its IP65 rating also edges ahead of the C100x’s IP64. The gap between the two phones is Rs 6,500 at their respective base prices.

That price difference buys 5G connectivity, a faster chipset, double the base storage, and a higher-rated display. For buyers in areas with limited 5G coverage, though, the C100x delivers the same battery endurance at a lower cost. The trade-off is clear, but Realme has not published guidance on which buyers should pick which model, leaving the two phones to compete within the same brand.

Battery Claims and Context

According to Realme’s lab testing, the C100x can stretch past three days on light use, handle around 13 hours of continuous gaming, run navigation for over 17 hours, and play video for roughly 20 hours. The company also claims that even at 1% charge, the phone can sustain about 30 minutes of calls or eight hours in standby. These figures come from Realme’s internal lab testing and are subject to real-world variation.

The brand also claims the battery retains over 80% of its original capacity after seven years of regular use, backed by what it calls AI Battery Protection technology. That claim covers 1,600 charge cycles, according to Realme’s product page.

For context, an 8,000mAh cell is no longer unusual at this price point. The Redmi 15A, priced at Rs 14,999, and the Redmi Note 17 series pushing cells up to 10,000mAh in the mid-range both demonstrate how rapidly battery capacity has escalated in India’s budget segment. Where the C100x differentiates is the combination of 45W charging alongside the large cell. The iQOO Z11i, for comparison, pairs a 6,500mAh battery with only 15W charging, a combination that drew widespread criticism for its slow charge times.

The Software Question

The C100x ships with Android 16 and Realme UI 7.0, but Realme has not confirmed how many years of OS updates or security patches the phone will receive. This is a notable omission given the phone’s durability-focused positioning and seven-year battery health claim.

Adding uncertainty is the broader software restructuring underway at Realme’s parent company. OPPO is reportedly planning to discontinue Realme UI globally and replace it with ColorOS across all its subsidiary brands. If that transition proceeds, C100x buyers may eventually receive ColorOS-based updates rather than Realme UI updates. Neither Realme nor OPPO has confirmed a timeline for this change or clarified how it would affect budget devices already in circulation.

What Remains Unknown

Several questions remain open after the C100x launch:

Software update commitment: Realme has not stated whether the phone will receive one, two, or more Android version upgrades, or how long it will receive security patches

Regular pricing after July 20: The Rs 14,499 launch price expires on July 20. Whether the Rs 14,999 standard price holds or fluctuates with marketplace promotions is not confirmed

Performance benchmarks from independent reviewers: Realme cites an AnTuTu score of 373,800, but third-party testing has not yet been published for the Indian variant

Glass protection comparison: No independent testing has compared the durability of Panda@MN228 glass (India) against ArmorShell glass (global) under equivalent conditions

What Happens Next

The C100x launch offer runs until July 20 at 11:59 PM IST. After that date, the phone’s effective price rises by Rs 500. No-cost EMI options for up to three months are available during the launch window.

Realme’s next scheduled sale event in India is the Narzo 100x 5G’s first sale on July 22 through Amazon India and Realme’s website. With both phones sharing the 8,000mAh battery headline, how buyers split between the Rs 14,499 4G option and the Rs 20,999 5G alternative will signal where India’s budget smartphone demand is actually concentrated.
