The MT6158 is a chipset designed for entry-level mobile devices, focusing on providing the essential mobile functions for budget-conscious consumers. It is perfect for users who need a simple device that can make calls, send text messages, and perform basic internet tasks such as checking emails or browsing lightweight websites. The single-core processor, with a speed of up to 260 MHz, offers enough performance to handle these basic tasks but lacks the power to support resource-intensive applications or multitasking.

In terms of multimedia, the MT6158 supports audio playback in standard formats such as MP3 and AAC, making it suitable for listening to music and podcasts. For video, it supports MP4 and 3GP formats, both of which are widely used for mobile media playback. However, the chipset is limited to basic VGA (640x480) camera support, which means that while it can capture photos and record videos, the quality will be much lower than that offered by higher-end smartphones with advanced camera systems.

The MT6158 also supports basic 2D graphics acceleration, making it capable of handling simple games and media applications. However, it does not support advanced 3D graphics or high-end gaming, meaning it is not designed for more demanding visual tasks.

Connectivity options include GPRS for 2G mobile data, which allows for basic internet browsing, email, and instant messaging. While the speeds are slower compared to modern 3G or 4G networks, GPRS is still adequate for simple tasks like reading emails, sending text messages, or browsing lightweight websites. The inclusion of Bluetooth enables users to connect wireless accessories, such as headsets or speakers, while the FM radio feature offers an entertainment option for users who want to listen to live radio.

The power efficiency of the MT6158 is another important feature. Devices equipped with this chipset can run for extended periods without needing to be charged frequently, which is a key advantage for feature phones and basic smartphones. This efficiency is especially beneficial for users who prioritize battery life over advanced features.

Finally, the expandable storage via microSD cards allows users to increase the storage capacity of their device to store additional music, photos, videos, or other media files. This makes the MT6158 a versatile solution for those who require additional storage but are working with limited internal memory.
