Realme C100: 8000mAh Battery, Specs, Price & What We Know

Let’s clear something up from the start: buying a Realme C100 is confusing. Not because of poor marketing, but because there isn’t just one C100. Instead, you get a whole lineup, each with slightly different names, specs, and sometimes even features depending on where you live. One version—the Realme C100 4G—shows off with an enormous 8,000mAh battery and 45W fast charging. It first appeared in Vietnam and made its way to Nigeria and the Philippines by mid-2026. There’s also a Realme C100 5G with a different processor and a smaller battery, plus a pair of Indian variants called the C100i and C100x.

Search for “Realme C100” online, and you’ll quickly run into a mess of overlapping specs and confusing listings. It’s genuinely tricky to figure out which model does what. That’s the whole point of this guide. First, I’ll untangle the models—then dig into what each version actually offers. Everything here comes straight from official specs, retail listings, and launch docs. If something is just a manufacturer’s lab claim, I’ll call it out so you know what’s real and what’s hype.

Realme C100 Variants: What’s Different?

That “C100” name covers a bunch of phones—different batteries, different processors, different durability. Here’s the breakdown:

Model Processor Battery Charging Display & Camera Durability Main Market & Launch Price

C100 4G Helio G92 Max 8,000mAh 45W wired, 10W reverse 6.8” HD+, 50MP/8MP IP69K (lab claim) Vietnam (VND 7,690,000), Philippines (₱16,999–₱19,999), Bangladesh (৳27,999 at G&G)

C100 5G Dimensity 6300 7,000mAh 45W wired 6.8” HD+, 50MP/5MP IP69K (lab claim) Global 5G (not India)

C100x (India) Unisoc T7250 8,000mAh 45W SuperVOOC 6.75” HD+, 50MP IP64 India (Rs 14,499 for 4GB+64GB)

C100i (India) Unisoc T7250 6,500mAh 15W wired 6.75” HD+, 50MP IP64 India (Rs 14,999 for 4GB+64GB)

- Realme C100 4G: Helio G92 Max, 8,000mAh battery, 45W wired charging, 10W reverse charging, 50MP rear, 8MP front, IP69K rating. RAM and storage varies a lot—Vietnamese versions had 6GB/8GB options, Philippine models shipped with 4GB/8GB paired with 256GB storage.

- Realme C100 5G: Uses Dimensity 6300, drops battery to 7,000mAh (but keeps 45W charging), and has a 5MP selfie camera. Not available in India as of now.

- Realme C100i (India): Regional variant, smaller 6,500mAh battery, slower 15W charging, IP64 splash resistance, Unisoc T7250 processor, only 4GB+64GB in India.

- Realme C100x (India): Same chip as C100i, but keeps the 8,000mAh battery and 45W charging, drops IP rating down to IP64, and launched at Rs 14,499.

So here’s the reality: don’t trust a review or price tag unless you know the exact variant. The Indian C100i/C100x are pretty different beasts compared to the main C100 4G sold in places like Bangladesh or Vietnam.

Build & Display

The Realme C100 4G uses a big 6.8-inch screen, but it’s HD+ (720 x 1570), not Full HD. Stuff looks a bit softer, but honestly, most buyers stop noticing after a couple of days. The upside? It’s got a punchy 120Hz refresh rate, so scrolling is smooth, plus a claimed 1,200 nits peak brightness that helps outdoors. The screen is protected by ArmorShell toughened glass.

Physically, it’s practical—glass on the front, plastic everywhere else, dual speakers, 8.6mm thick, and weighs about 219 grams. With an 8,000mAh battery inside, staying under 9mm thick is impressive.

Realme markets IP69K certification for the 4G model (lab claim). They say it’ll survive underwater for 30 minutes up to 6 meters, withstand high-pressure sprays, and handle drops up to 2 meters. Take that with a grain of salt—those ratings came from lab tests, not everyday use. Water damage still isn’t covered under warranty. You can choose from three finishes.

Performance & Software

Inside the C100 4G is MediaTek’s Helio G92 Max, a budget 4G processor on an older 12nm process. It’s fine for calls, WhatsApp, Facebook, YouTube, navigation, or banking. Push it with demanding games? You’ll hit its limits quickly. Storage is eMMC 5.1, not UFS, so app installs and file moving are slower—though there’s a dedicated microSD slot.

RAM and storage vary—4GB/6GB/8GB RAM, up to 256GB storage, depending on market. If you want 5G, you’ll need the C100 5G variant with Dimensity 6300, a more efficient chip.

Both versions run Android 16 with Realme UI 7. It’s standard stuff: clean layout, some decent battery management tools.

Camera

Don’t expect much fancy stuff. The rear camera is a 50MP main sensor with PDAF, 1080p video, and an f/1.8 lens. Front cameras: 8MP for 4G, 5MP for 5G. No ultrawide, no zoom. Just basics. In daylight, you can take pretty good shots for social media and docs. At night, quality dips—grainy, soft images, as expected for a budget phone.

Battery & Charging

Now, the headline: the C100 4G packs an absurd 8,000mAh battery. The Indian C100i only has 6,500mAh and slow 15W charging, but the proper C100 4G gets full 45W SuperVOOC charging and can reverse charge at 10W. You can use it as a power bank for buds or another phone.

Math says pushing 30Wh of power at 45W could take around 40 minutes. Realistically, phones slow charging as they hit 80% to protect the battery, so a full charge takes just over an hour. That’s fast for a battery this big—way quicker than charging on a 15W brick, which would take forever.

How Does It Compete?

Big-battery budget phones are everywhere now, especially late in 2026. Compare C100 4G to the closest rivals:

• Vivo Y32 (2026): 8,000mAh, 44W charging, IP68/IP69, UFS 2.2, 6nm Unisoc T7300, 4/6GB RAM.

• Honor X6e (4G): 7,500mAh, 45W charging, 3.5mm jack, Helio G81 Ultra, IP64 only.

• itel A300+: 7,000mAh, 6.78-inch 120Hz, IP65, lower price.

Charging speeds are nearly identical. Storage is faster on Vivo, durability is best with Realme and Vivo, battery size is tied or close.

Realme C100 Pricing: Bangladesh & Beyond

Prices bounce around depending where you buy:

• Bangladesh: Realme C100 4G is officially listed at BDT 27,999 (Gadget & Gear, but out of stock as of late October 2026).

• Vietnam: Earlier launch at VND 7,690,000 (~$292 USD, ~BDT 35,000), 6GB/8GB RAM versions.

• Philippines: ₱16,999 for 4GB+256GB (~BDT 35,200), ₱19,999 for 8GB+256GB (~BDT 41,400).

Indian numbers (Rs 14,999 for C100i, Rs 14,499 for C100x) don’t really apply here, since those are watered-down versions. If you shop in Bangladesh, stick to authorized sellers, check for restocks around ৳27,999, and always look at the RAM/storage label.

Pre-Purchase Checklist

1. Double-check the model suffix: Make sure you’re getting the main C100 4G, not a slower, less durable C100i or C100x.

2. 4G vs 5G: Most C100s in Bangladesh/Southeast Asia are 4G only. Need 5G? Go hunting for the Dimensity 6300-based C100 5G.

3. Regional RAM/storage: Specs change by region. Bangladesh, Vietnam, Philippines all offer different combos—look before buying.

4. 45W charger included: The fast adapter should be in your box, or you’ll miss out on those speedy charges.

5. IP69K as lab rating: It’s solid for accidental spills or rain, but don’t push your luck with underwater photography.

Who Should Get the C100?

If you’re constantly draining your phone, work outdoors, ride-share or deliver, travel a lot, or just hate power banks—the Realme C100 4G is built for you. The huge battery, fast charging, reverse charging, and rugged build make it a reliable workhorse. But, if you’re into fancy screens, fast storage, or gaming, you’ll want something else.

Bottom Line

The Realme C100 4G is all about endurance—a big battery, quick charging, and a sturdy shell. Just watch for confusing variant names, check availability at shops like Gadget & Gear (listed at ৳27,999), and confirm which version you’re getting.
