The realme C100i 4G is the price-conscious choice if it costs substantially less where you live and an 8MP rear camera with 15W charging meets your needs. The realme C100X is worth considering for its listed 50MP rear camera and faster charging—but those upgrades do not by themselves prove better photos or longer battery life. Both are listed with a Unisoc T7250 chip and a large 120Hz HD+ display in the sources reviewed. Prices and some specifications vary by market, so compare the exact local variants before buying.
At a glance: realme C100i 4G vs C100X
| Feature | realme C100i 4G | realme C100X |

| Chipset | Unisoc T7250, listed by 91mobiles and realme India | Unisoc T7250, listed by 91mobiles and realme Italy |
| Display | 6.8-inch, 720 × 1570, 120Hz, per 91mobiles | 6.8-inch, 720 × 1570, 120Hz, per 91mobiles |
| Rear camera | 8MP wide-angle, per realme India | 50MP, per 91mobiles and Indonesian launch coverage |
| Front camera | 5MP, per 91mobiles | 5MP, per 91mobiles |
| Battery and charging | India product page: 6,500mAh and 15W | Italy specification page: 7,500mAh typical (7,285mAh rated), up to 45W |
| Example price evidence | India official store displayed ₹16,499 for selected 4GB+64GB; 91mobiles displayed ₹14,999 | 91mobiles displayed ₹16,999; Indonesia launch price was Rp 3.399 million for 6GB/128GB |
These are not all matched-market or matched-variant figures. The comparison prices are time-sensitive observations, and the Indonesia figure is a May 2026 launch price, not a current global street price. Sources: 91mobiles comparison, realme India C100i store listing, realme Italy C100X specifications, and detikInet Indonesia launch report.
How much more does the C100X cost?
There is no single worldwide price difference. On the 91mobiles comparison page, the observed India prices were ₹14,999 for the C100i and ₹16,999 for the C100X—a ₹2,000 gap at the time the page was checked. Separately, realme India’s store displayed ₹16,499 for a selected C100i 4GB+64GB configuration. Those listings may not represent the same storage variant, seller conditions, or offer, so the figures are not a like-for-like price guarantee.

For another market-specific reference, detikInet reported May 2026 Indonesian launch prices of Rp 3.399 million for the C100X 6GB/128GB and Rp 2.499 million for the C100i 4GB/128GB. The C100i also launched there at Rp 2.799 million for 4GB/256GB and Rp 2.999 million for 6GB/128GB. The report noted lower flash-sale prices that were temporary.

To judge the premium where you shop, compare the same RAM and storage capacity, then include retailer discounts, warranty coverage, and return terms. Do not treat an India listing or an Indonesian launch price as a current price in another country.
Does the C100X have a better camera?
Rear camera resolution
The clearest camera specification difference is resolution: realme India’s C100i listing specifies an 8MP wide-angle rear camera, while 91mobiles and detikInet list a 50MP rear camera for the C100X. That is a substantial difference in the number of pixels recorded, but megapixels alone do not establish photo quality. Sensor size, lens, image processing, lighting, and camera software also matter; the available sources do not provide matched independent camera tests.
Front camera
91mobiles lists a 5MP front camera for both models, and detikInet also reports 5MP for the Indonesia-market C100i. Treat the C100X front-camera figure as comparison-site-reported unless you confirm the specification for the exact regional SKU.
Battery and charging: compare the regional specifications carefully
The official India C100i product page highlights a 6,500mAh battery and 15W charging. Realme Italy’s C100X specification page gives 7,500mAh typical capacity (7,285mAh rated) and support for up to 45W fast charging. On those specific pages, the C100X has the higher stated capacity and substantially faster maximum charging.

- International model: no warranty in USA. Compatible with most GSM carriers such as T-Mobile, AT&T, MetroPCS, etc. Will not work with CDMA carriers such as Verizon, Cricket, Boost.
Other sources report different battery figures, including 7,000mAh for the C100i and 8,000mAh for the C100X. Because the claims vary across comparison and Indonesia-market reporting, use the specification for the market and SKU you intend to buy rather than assuming one capacity applies everywhere. The listed capacity and charging ceiling also do not establish actual runtime or charging time; no matched independent battery or charging test is established here.
Display and chipset: similar on paper
91mobiles lists both phones with a 6.8-inch display at 720 × 1570 resolution and 120Hz refresh rate. DetikInet describes the Indonesia-market models as 6.8-inch 120Hz IPS LCDs. This points to a similar large, high-refresh HD+ class of screen, not proof that brightness, color, panel quality, or dimensions are identical in every market.

The same comparison lists the Unisoc T7250 for both, and the official realme India C100i and Italy C100X pages also identify that chipset. That shared specification is not a controlled performance comparison; it does not establish identical performance in every configuration or workload.

Realme Italy’s C100X specification page lists realme UI on Android 16, LTE bands, no 5G NR, Wi-Fi 5, Bluetooth 5.2, USB-C, a 3.5mm audio jack, and NFC availability that depends on the region. These are Italy-market specifications, not a guarantee that every C100X sold elsewhere has the same bands or features. Confirm local network compatibility and NFC before purchase.

The India C100i listing includes 4GB+64GB and 4GB+128GB configurations. Its product Q&A mentions two major OS updates and three years of system maintenance support, but the page does not expose a dated policy statement. Check the current product or support page for the promise applicable to the unit you are buying rather than assuming the same support terms across regions or variants.
DetikInet reports IP64 and military-grade shock-resistance or ArmorShell claims for the Indonesia-market models. These are manufacturer claims reported by the publication, not evidence of independent durability testing. Check the exact local model’s rating and warranty terms; do not treat a marketing durability claim as coverage for accidental damage.
Quick Recap
Which phone should you choose?
Choose the C100i if the local discount is meaningful
- You can buy a specific C100i variant for materially less than the comparable C100X.
- An 8MP rear camera is sufficient for your use, and you do not need the C100X’s higher listed resolution.
- You are comfortable with the 15W charging figure on the India product page, if that is the relevant market specification.
Consider the C100X if its upgrades justify the local premium
- You value the 50MP rear-camera specification, while recognizing it does not guarantee better image quality.
- Faster charging matters to you, and the C100X SKU sold in your market confirms the higher charging support.
- The local C100X price is close enough to a comparable C100i variant that those features are worth the difference to you.
Verify before checkout
- Match RAM and storage rather than comparing base and higher-capacity variants.
- Confirm the battery, charging, camera, network bands, NFC, software, and warranty on the local SKU’s product page or retailer listing.
- Check the seller’s current price, stock, return policy, and warranty; prices and offers can change.
Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
