Realme C100 5G: A 7,000mAh Battery and 144Hz Display in a Budget 5G Phone
Realme has released the C100 5G in Thailand, and its features are impressive for its price range.
It comes with a 7,000mAh battery and 45W fast charging, a 6.8-inch LCD display with a 144Hz refresh rate, and a 50MP main rear camera with f/1.8 aperture and autofocus. The phone uses the MediaTek Dimensity 6300 chipset with 5G support and runs Android 16 with Realme UI 7.0. It also has IP64 dust and splash resistance. Prices start at THB 6,999, which is about Rs. 20,000 at current exchange rates.
Sales start on April 22, 2026, on Lazada and other online stores in Thailand. The phone comes in two colors: Blooming Purple and Sprouting Green. There is no confirmation yet for India, but since Realme's C-series is popular there, a launch in India is likely.

The Rs. figures above are direct THB to INR conversions and will not reflect actual India pricing if it launches here. Watch Realme India's official channels for announcements.
Display: 144Hz on a Budget Phone Deserves Attention
One of the standout features of the Realme C100 5G is its 6.8-inch HD+ LCD display with a 144Hz refresh rate, especially at this price.
Most budget smartphones around Rs. 20,000 usually have 90Hz or 120Hz displays. Having 144Hz at this price is rare and improves the user experience, especially for gaming. While the difference between 120Hz and 144Hz is small in daily use, it becomes noticeable during fast-paced games. For budget gamers, 144Hz is a valuable feature.
The 180Hz touch sampling rate works well with the 144Hz display, especially for gaming. This rate means the screen checks for your touch 180 times per second, making controls feel more responsive in games. While it doesn’t matter much for browsing or social media, it helps a lot in fast-paced games where quick reactions are important.
The screen’s peak brightness of 900 nits is good for indoor use and shaded outdoor areas. In direct sunlight, it’s not as bright as high-end AMOLED screens, but for a budget phone, 900 nits is reasonable and expected.
The display uses HD Plus resolution instead of Full HD Plus, which means lower pixel density at 720 by 1612 pixels on a 6.8-inch screen. Text and images look clear at normal viewing distances, but close inspection shows less sharpness. For everyday use like YouTube, Instagram, and WhatsApp, most people won’t notice the difference.
The screen is protected by Panda-MN228 glass, which adds scratch resistance. While it’s not as famous as Gorilla Glass, Panda glass still helps protect against everyday scratches from things like keys or coins.
HD Plus vs Full HD Plus: At a typical phone viewing distance of 25 to 35cm, HD Plus at 720p on a 6.8-inch screen delivers approximately 260 PPI. Full HD Plus would deliver around 390 PPI. For video calls, social media browsing, and casual use, 260 PPI is perfectly acceptable. For reading small text or viewing detailed photographs, the difference becomes visible on close inspection.
Performance: Dimensity 6300 With 5G for Budget Daily Use
The MediaTek Dimensity 6300 gives the Realme C100 5G smooth everyday performance and 5G support at a price that’s affordable for entry-level buyers.
For daily tasks like calls, WhatsApp, Instagram, YouTube, browsing, and light gaming, the Dimensity 6300 offers smooth and responsive performance. With up to 6GB RAM, switching between apps is quick. The 128GB storage is fast and spacious, and you can add more with a microSD card if needed.
Playing demanding games like BGMI on high settings will challenge the Dimensity 6300. On medium settings, most popular games run smoothly, but at high or ultra settings, you may notice frame drops. The Realme C100 5G isn’t meant to be a gaming phone, but it handles casual gaming and daily tasks well.
The phone runs Android 16 with Realme UI 7.0. Having Android 16 out of the box is a plus for a budget phone and should mean a good update cycle. Realme usually provides three years of security updates for its C-series phones.

Battery: 7,000mAh Is the Phone's Defining Feature
The 7,000mAh battery is the main feature that sets the Realme C100 5G apart from other budget 5G phones. It’s the top reason to pick this phone over others at a similar price.
Most budget 5G phones in the Rs. 15,000 to Rs. 20,000 range have 5,000mAh batteries. The Realme C100 5G’s 7,000mAh battery gives you 40% more capacity. If you often run out of battery before the day ends, this phone solves that problem.
Thanks to the efficient Dimensity 6300 chipset and HD Plus display, the battery life should be excellent. With moderate use—calls, social media, YouTube, and some gaming—you can expect 1.5 to 2 days between charges. Even heavy users should finish the day with over 30% battery left.
The 45W fast charging can fill the 7,000mAh battery from empty in about 90 to 100 minutes. Charging to 50% takes around 40 minutes, which is enough for several hours of use. For a budget phone, 45W charging on such a large battery is impressive, since many others only offer 18W or 25W charging.
Compared to other budget phones, the Samsung Galaxy A06 has a 5,000mAh battery, the Poco M7 5G has 5,160mAh, and the Redmi 15A has 6,300mAh. The Realme C100 5G’s 7,000mAh battery is the largest in this price segment. If battery life is your top priority, no other phone at this price matches it.

Camera: 50MP for Everyday Budget Photography
The Realme C100 5G’s 50MP main rear camera with f/1.8 aperture and autofocus is a good fit for everyday photography needs in this price range.
The f/1.8 aperture is wider than what many budget phones offer, so it lets in more light in dim conditions. In good daylight, the 50MP sensor takes detailed photos with accurate colors, great for social media or personal use. Autofocus works quickly on still subjects and does a decent job tracking moving ones up close.
Low-light photography shows the expected limitations of a budget single-sensor without a dedicated night-mode processing pipeline. In dim indoor environments and evening outdoor settings, noise increases and detail reduces. The LED flash helps in very dark conditions but creates flat, harsh lighting at close distances.
The 5MP front camera is fine for selfies and video calls. In good light, selfies look clear and accurate, but in low light, photos can appear softer and noisier due to the sensor’s limits.
The phone records video at 1080p and 30fps, which is enough for social media and family videos. There’s no 4K support, but that’s normal for this price range.

Build and Durability: IP64 for Everyday Protection
The Realme C100 5G has an IP64 rating, which means it’s fully protected against dust and can handle water splashes from any direction. This is a useful durability feature that most budget phones at this price don’t offer.
IP64 means the phone is completely protected from dust and can handle splashes of water from any direction. Everyday situations like rain, hand washing, or accidental spills are covered. However, it’s not safe against water jets or being submerged, so avoid using it in heavy rain or underwater.
The side fingerprint scanner unlocks the phone quickly and reliably. Face Unlock is also available for easy access, especially in well-lit places.
The Realme C100 5G is 8.88mm thick and weighs 224 grams, which is heavier than most budget phones because of its large battery. You’ll notice the weight in your pocket or during long one-handed use. This is the trade-off for having a 7,000mAh battery, so consider this if you prefer lighter phones.

Who Should Buy the Realme C100 5G
Choose this phone if long battery life is your top priority. The 7,000mAh battery is the biggest in the budget 5G segment at this price and solves the problem of running out of battery before the day ends.
Buy it if you want 144Hz on a budget. Smooth scrolling and gaming at 144Hz at approximately Rs. 20,000 equivalent is genuinely rare, and the Realme C100 5G delivers it.
Buy it if 5G connectivity at the lowest possible price matters to you. The Dimensity 6300 brings 5G to a price tier where most phones are still 4G only.
If you’re in India, wait for the official Realme India launch before buying. Grey market imports won’t have an Indian warranty or service support.
Consider alternatives if: Full HD Plus resolution matters. The Redmi 15A at Rs. 12,999 has HD Plus, but the Poco M7 5G at approximately Rs. 12,999 offers Full HD Plus if display sharpness is the priority.
Look at other phones if the 224-gram weight is a concern. Lighter budget phones are available, but they usually have much smaller batteries.
Final Verdict
The Realme C100 5G is a budget 5G phone focused on one main strength: it has the biggest battery in its price range and fast 45W charging.
7,000 mAh at approximately Rs. 20,000 equivalent, paired with a 144Hz display, 50MP camera, DimenA 7,000mAh battery for about Rs. 20,000, along with a 144Hz display, 50MP camera, Dimensity 6300, IP64 protection, and Android 16, is a combination you won’t find in other phones at this price. The HD Plus resolution and 5MP selfie camera are real limitations, but they don’t take away from the phone’s main strengths. At a competitive price in the Rs. 14,999 to Rs. 18,999 range, it becomes one of the most compelling budget 5G options available in 2026 for buyers whose priority is never running out of battery.
Bottom line: With a 7,000mAh battery, 45W charging, and a 144Hz display for about Rs. 20,000, the Realme C100 5G is the top choice for battery life among budget 5G phones launched in April 2026. India launch is yet to be confirmed. The main trade-offs are its 224g weight and HD Plus resolution.
