The Redmi 13C, priced below Rs 12,000 in India, enters the market as a 5G-enabled smartphone with a sleek premium design. Boasting a 90Hz display, a substantial 5,000mAh battery, and a 50-megapixel dual rear camera setup, it positions itself to compete with other 5G models like the Lava Blaze Pro 5G and Samsung Galaxy M14. The Redmi 13C 5G is available in three colors – Startrail Silver, Startrail Green, and Starlight Black – and offers multiple configurations: the 4GB RAM + 128GB storage variant starts at Rs 10,999, the 6GB + 128GB model is priced at Rs 12,499, and the 8GB + 256GB variant is available for Rs 14,499. Sales are set to commence on December 16 through channels such as Amazon, the Mi online store, and other online retailers.

Featuring a 6.74-inch LCD display with a 90Hz refresh rate, 180Hz touch sampling rate, and 600 nits peak brightness, the Redmi 13C offers a teardrop notch design and Gorilla Glass 3 protection. The device is both dust and splash-resistant. Powering this budget phone is a 6nm MediaTek Dimensity 6100+ processor, the same chipset found in the Realme 11x and Realme 11 5G. Additionally, the phone supports RAM extension up to 16GB using its internal storage. Operating on the Android 13 platform, the device houses a dual rear camera system led by a 50-megapixel primary sensor. A robust 5,000mAh battery fuels the device, supporting 18W fast charging, although the bundled charger is a 10W variant. While an official IP rating is not provided, Xiaomi assures users of its splash-resistant and dust-protected features. Connectivity options include Wi-Fi ac, Bluetooth 5.3, a 3.5mm headphone jack, and a USB Type-C port.

Gmail biggest security update

Google has divulged information about an enhanced technique employed to enhance spam detection on its free email service, Gmail. In the latest Google Security blog post, the tech giant emphasizes that this marks one of the most substantial defense upgrades Gmail has undergone in recent years. Google asserts that its latest model demonstrates superior text identification capabilities and has elevated spam detection by an impressive 38%. Text classification models, crucial for identifying harmful content like phishing attacks, inappropriate comments, and scams across platforms such as Gmail, YouTube, and Google Play, encounter challenges due to spammers employing adversarial text manipulations. These tactics, including homoglyphs, invisible characters, and keyword stuffing, make it difficult for machine learning models to classify such texts.

To enhance the stringency and efficiency of text classifiers, Google has introduced a new multilingual text vectorizer named RETVec (Resilient & Efficient Text Vectorizer). This innovation aids spam filter models in delivering more precise classification performance while significantly reducing computational costs. Google details how RETVec is utilized to safeguard Gmail inboxes. Over the past year, Google extensively evaluated RETVec's effectiveness and found it to be highly impactful for security and anti-abuse applications. Replacing Gmail's previous text vectorizer with RETVec resulted in a notable 38% improvement in the service's spam detection rate and a 19.4% reduction in the false positive rate. Additionally, the use of RETVec led to an impressive 83% reduction in the model's power consumption.

Notably, RETVec is language-agnostic and works with "all UTF-8 characters" without requiring any text preprocessing. This characteristic makes it ideal for on-device, web, and large-scale text classification deployments. Google asserts that "models trained with RETVec exhibit faster inference speed due to its compact representation." Furthermore, these smaller models reduce computational costs and decrease latency, which is critical for large-scale applications and on-device models. Models trained with RETVec can be converted to TFLite for deployment on mobile and edge devices. The open-source model is available on Github, contributing to the broader accessibility of this innovative technology.

OnePlus 12 launched in China

OnePlus has unveiled its 10th-anniversary flagship smartphone, the OnePlus 12, in China. This latest device boasts wireless charging, an enhanced USB port for faster connectivity, and an upgraded camera system. Offering various RAM and storage configurations, the OnePlus 12 features a glass sandwich construction. Fueled by the Snapdragon 8 Gen 3 chipset and equipped with a VC cooling system for efficient thermal dissipation, the smartphone represents a notable addition to the Chinese company's product lineup.

The OnePlus 12 builds upon the success of its predecessor, the OnePlus 11, launched in China in 2022 and subsequently in India earlier this year. Noteworthy improvements include the reintroduction of wireless charging, a speedier USB port, and an enhanced camera system. The device is available in different RAM and storage variants, with the base model supporting 12GB RAM and 256GB storage, priced at CNY 4,299 (approximately Rs 50,500). Other configurations, including 16GB + 512GB, 16GB + 1TB, and 24GB + 1TB, are priced at CNY 4,799 (almost Rs 56,400), CNY 5,299 (almost Rs 62,300), and CNY 5,799 (almost 68,200), respectively. Color options include Rock Black, Pale Green, or White.

The design language of the OnePlus 12 remains consistent with its predecessor, featuring a glass sandwich construction with a central metal frame and IP65-rated water and dust resistance. The smartphone showcases a 6.82-inch curved OLED display supplied by BOE, supporting a resolution of 3168 x 1440 pixels (QHD+), 510 PPI, and a variable refresh rate (LTPO) ranging from 1 to 120Hz. The 10-bit screen offers up to 4500 nits of local peak brightness and 2160Hz of PWM dimming.

Driving its performance is Qualcomm's latest Snapdragon 8 Gen 3 chipset, coupled with LPDDR5x RAM and UFS 4.0 storage. For efficient thermal management, the phone integrates a 9140mm² VC (Vapor Chamber) cooling system covering an area of 38,547mm². The camera setup, akin to the OnePlus Open and the Oppo Find N3, includes a 50MP Sony LYT-808 primary sensor with OIS, a 64MP OmniVision OV64B sensor with OIS-assisted 3x periscope zoom lens, and a 48MP Sony IMX581 ultra-wide unit with autofocus. The front features a 32MP shooter, all tuned with Hasselblad's image processing.

Connectivity options abound with dual SIM support, 5G connectivity, WiFi 7, Bluetooth 5.4, GNSS, NFC, and USB 3.2 Gen 1 ports. Notable features include an alert slider, an IR blaster, an x-axis linear vibration motor, and a dual stereo speaker setup. Running on ColorOS 14 based on Android 14, the OnePlus 12 is powered by a 5,400mAh battery and supports 100W wired, 50W wireless charging, as well as 10W reverse wireless charging. The smartphone is currently available for pre-order in China and is set to go on sale on December 11.
