Realme C100 4G Launched with 8000mAh Battery, IP69K Rating and 45W Charging

The Realme C100 4G has officially been announced, and it arrives with a specification sheet that is difficult to ignore at this price point. At the centre of the device is an 8000mAh battery, one of the largest found in any budget-tier smartphone currently available, complemented by an IP69K dust and water resistance rating, a 120Hz display, and Android 16 out of the box.

For consumers seeking a budget Android phone in 2026 that prioritises endurance and durability, the Realme C100 4G presents a compelling proposition worth examining in detail.

What Is the Realme C100 4G?

The Realme C100 4G is the most recent addition to Realme’s expanding C100 series. It sits alongside the C100 5G variant but differentiates itself in one significant area: battery capacity. Whilst the 5G model carries a 7000mAh cell, the 4G version increases this to 8000mAh, making it the larger-battery option within the lineup.

The device is powered by the MediaTek Helio G92 Max chipset, which delivers reliable everyday performance, supports smooth multitasking, and handles light gaming without difficulty at this price bracket.

Realme C100 4G Battery Life: How Long Does It Last?

The 8000mAh battery is the headline feature of the Realme C100 4G. Realme’s official figures indicate the following real-world endurance estimates on a single charge:

• Over 23 hours of continuous video streaming
• More than 20 hours of navigation
• In excess of 13 hours of gaming

While actual results will vary depending on usage patterns and network conditions, a phone with an 8000mAh battery is well-positioned to last most users comfortably beyond a full day of moderate to heavy use.

When recharging is required, the Realme C100 4G supports 45W wired fast charging to restore battery levels efficiently. It also features reverse wired charging at up to 10W, allowing the device to be used as a power source for other accessories such as earbuds or a secondary phone.

Display: 6.8-Inch 120Hz Panel with 1200 Nits Peak Brightness

The Realme C100 4G is built around a 6.8-inch IPS LCD panel with HD+ resolution and a 120Hz refresh rate. The higher refresh rate is a meaningful inclusion at this price tier, as it produces noticeably smoother scrolling and transitions compared with standard 60Hz screens.

The display reaches a peak brightness of 1200 nits, which provides adequate legibility in outdoor environments and under direct sunlight. It is further protected by ArmorShell glass, which offers an additional layer of resistance against everyday scratches and accidental impacts.

IP69K Rating: Understanding What It Means

The Realme C100 4G carries an IP69K ingress protection rating, a distinction that deserves particular attention. The majority of flagship smartphones are rated to IP68, which certifies submersion in up to 1.5 metres of fresh water. IP69K, by contrast, certifies the device to withstand high-pressure, high-temperature water jets directed from multiple angles.

This standard is most commonly associated with industrial and outdoor equipment designed for demanding environments. Its presence on a budget smartphone is genuinely uncommon, and it makes the Realme C100 4G a practical consideration for professionals and users who regularly operate in outdoor or high-exposure settings.

Realme C100 4G Full Specifications

Camera Setup

The rear camera configuration on the Realme C100 4G consists of a 50MP primary sensor with an f/1.8 aperture, paired with a secondary auxiliary lens. The wide aperture on the main sensor supports improved light intake, which should translate to reasonably detailed shots under well-lit conditions.

On the front, an 8MP camera is housed within a punch-hole cutout in the display. It is adequately specified for video calls and standard social media use, though it is not the focal point of this device’s value proposition.

Software: realme UI 7.0 Built on Android 16

The Realme C100 4G launches with realme UI 7.0, based on Android 16. Shipping with the latest version of Android at launch is a notable advantage for a budget device, as it ensures access to the most current platform features and security patches from day one, without requiring the user to wait for an update cycle that may be delayed or uncertain.

Realme C100 4G Price and Availability

The Realme C100 4G is currently available through retail channels in Vietnam at a price of VND 7,690,000, which is approximately USD 292. It is offered in three colour options: White, Purple, and Brown.

A broader international rollout has not yet been confirmed. However, given Realme’s established distribution presence across markets such as India and Southeast Asia, a wider release in the coming weeks is a reasonable expectation.

Is the Realme C100 4G Worth Considering?

At under USD 300, the Realme C100 4G offers a specification set that competes favourably within its category. The 8000mAh battery positions it well above the standard for budget devices, and the IP69K rating provides a level of environmental protection that most smartphones in this segment do not offer.

The trade-offs are consistent with what one would expect from a budget-tier product: HD+ resolution in place of FHD+, eMMC 5.1 storage rather than faster UFS, and a camera system that is functional without being exceptional. For users whose priorities are battery longevity, physical durability, and strong value for money, the Realme C100 4G makes a well-rounded case.

It stands as one of the more substantively equipped budget Android phones to be announced in 2026.
