Phones with 12 GB of RAM are no longer reserved for premium segments. In the sub-Rp 6 million range, several models now offer enough memory to stay smooth for multitasking, gaming, and heavier app use over the long term.
The appeal is not only about speed today. Larger RAM also gives Android devices more room to handle future software demands, which makes these models more practical for users who want a phone that will remain responsive for years.
Infinix GT 30 Pro is the most affordable option in this group at Rp 4,699,000. It combines 12 GB of RAM with 512 GB of storage and is powered by the MediaTek Dimensity 8350 Ultimate.
The phone uses a 6.78-inch AMOLED display with a 144Hz refresh rate and a peak brightness of up to 4500 nits. Its 5500 mAh battery supports 45W wired charging and 30W wireless charging, although it does not provide external memory expansion and still uses USB Type-C 2.0 for data transfer.
2. iQOO Z10
Priced at Rp 5,499,000, the iQOO Z10 stands out for endurance. It pairs 12 GB of RAM and 512 GB of storage with a 7300 mAh battery and 90W fast charging.
Performance comes from the Snapdragon 7s Gen 3 built on a 4 nm process, while the display is a 6.77-inch AMOLED panel with a 120Hz refresh rate and peak brightness of 5000 nits. The main trade-offs are its 199-gram weight and the absence of an ultrawide camera, since the rear setup is limited to a 50 MP main camera with OIS and a 2 MP depth sensor.
3. Redmi Note 15 Pro 5G
Redmi Note 15 Pro 5G sits right at the top of the budget at Rp 5,999,000. Its strongest selling points are a 200 MP main camera with OIS, 12 GB of RAM, 512 GB of storage, and a 6580 mAh battery.
The phone also carries a 6.83-inch AMOLED display with a 120Hz refresh rate and the MediaTek Dimensity 7400-Ultra chipset. Its compromises are a 210-gram body and 45W charging, which is slower than some rivals with similarly large batteries.
4. realme 15 5G
realme 15 5G is sold at Rp 5,299,000 and takes a different approach by focusing on balance. Despite its 7000 mAh battery, the phone remains relatively light at 180 grams and only 7.7 mm thick.
It uses the MediaTek Dimensity 7300+ chipset, a 6.77-inch AMOLED display with a 144Hz refresh rate, and 12 GB of RAM. Durability is another highlight, with IP69 and MIL-STD-810H certification, but the 256 GB internal storage has no expansion slot, which may be limiting for users who store a lot of large files.
5. Tecno Camon 50 Pro 5G
Tecno Camon 50 Pro 5G is priced at Rp 5,999,000 and is clearly aimed at camera-focused buyers. It uses a 50 MP Sony LYT-700C main camera with OIS, a 50 MP telephoto lens with 3x optical zoom and OIS, and an 8 MP ultrawide camera.
That imaging setup is paired with 12 GB of RAM, 256 GB of storage, a curved 6.78-inch AMOLED display with a 144Hz refresh rate, Android 16, and a 6500 mAh battery. The main limitation is its MediaTek Dimensity 7400 Ultimate chipset, which still uses a 6 nm process and is considered less modern in efficiency than the 4 nm competitors in this list.
What matters more than the RAM number
The five models show that 12 GB of RAM can be found in phones with very different strengths. Some lean toward raw performance and storage, while others prioritize battery life, durability, or camera hardware.
For the lowest entry price, the Infinix GT 30 Pro looks the most aggressive because it already offers 12 GB and 512 GB below Rp 5 million. For battery-heavy use, the iQOO Z10 is the most obvious endurance pick, while realme 15 5G offers a lighter body and stronger durability ratings.
Photography users may find the Redmi Note 15 Pro 5G and Tecno Camon 50 Pro 5G more compelling, but for different reasons. Redmi focuses on a 200 MP main camera, while Tecno adds a 3x optical zoom telephoto lens that is uncommon in this price class.
In practice, the smartest choice depends on which compromise feels least painful. RAM 12 GB helps all of these phones age more gracefully, but battery size, charging speed, storage capacity, and camera hardware still define the real-world experience.
