Hello! Based on your requirements, let's compare the Itel S23 4G, Tecno Spark 10c, and Infinix Hot 30i.
Camera:
The Itel S23 4G features a dual rear camera setup with a 13MP main sensor and a VGA secondary sensor. The Tecno Spark 10c also has a dual rear camera setup with a 13MP main sensor and a VGA secondary sensor. On the other hand, the Infinix Hot 30i comes with a single 13MP rear camera. All three phones should be able to provide decent camera performance with minimal delay, although the Itel S23 4G and Tecno Spark 10c have an advantage with the dual camera setup.
Battery:
The Itel S23 4G comes with a 3000mAh battery, while the Tecno Spark 10c and Infinix Hot 30i both have larger 5000mAh batteries. With a larger battery capacity, the Tecno Spark 10c and Infinix Hot 30i should offer better battery life compared to the Itel S23 4G.
Charging:
Regarding charging speed, none of the three phones mentioned have fast charging capabilities. So, they should charge at a standard rate. However, it's worth noting that the charging time may vary based on factors like the charger's output and cable quality.
Refresh Rate and Touch Sampling Rate:
Unfortunately, the Itel S23 4G, Tecno Spark 10c, and Infinix Hot 30i all come with standard 60Hz refresh rates and touch sampling rates. You may experience some lag or delay while scrolling through social media apps, but it shouldn't be too noticeable. As for bugs, it's difficult to predict if any specific phone will have issues, as it can vary from unit to unit.
Considering your budget of 5k, these are the options available. However, if you're open to other recommendations, you might want to consider the Realme C11. It offers a large 5000mAh battery, a dual rear camera setup (13MP + 2MP), and a MediaTek Helio G35 processor, which should provide a smooth experience for light gaming and social media usage.
Remember to check the specific features and user reviews of each phone before making a final decision.
