This guide is based on published specifications, not hands-on testing. Confirm the exact variant on the product page before buying. Last updated: September 2026.
Quick verdict
A low-cost phone for calls, WhatsApp, browsing and video. Performance is basic, the rear camera is only 8MP and there is no 5G, so it is not for heavy users or photographers.

Display and design
You get a 6.78-inch screen with a 120Hz refresh rate, a big display for the price. It is a 720p LCD with about 700 nits of peak brightness. The body is 7.7mm thin with a glass front and a plastic back, and it is splash-resistant (IP64) and drop-resistant to 1.5m. Colours are Shadow Black, Cloudline Blue, Polaris Titanium and Sunlike Orange.
Performance and software
The Helio G81 Ultimate is an entry-level chip. WhatsApp, calls, banking and video streaming are fine, while gaming and heavy multitasking will feel slow. There is 4GB of RAM, storage of 64GB or 128GB, and a microSD slot for more space. It ships with Android 16 and XOS 16.
Cameras
An 8MP rear camera and an 8MP front camera are enough for casual photos and video calls in good light. Expect limited detail and weak night photos. Video goes up to 1440p at 30fps.
Battery and charging
The 5,200 mAh battery gets through a day of typical use. Charging is 15W, so overnight charging is the norm. It can also reverse-charge at 5W.
Strengths
- Very affordable with a large 120Hz screen
