Explanation
The symptoms - sluggishness, excessive heat, and app crashes - on a 6-month-old device point to two likely culprits. First, a defective or degrading battery (B) can cause thermal throttling, where the OS slows the CPU to protect itself from heat, leading to slowness and instability. A swelling or failing battery is a known cause of heat and crashes. Second, unnecessary applications (E) running in the background consume CPU cycles and RAM, which generates heat and starves other apps of resources - explaining the crashes. Option A (stopping running apps) is only a temporary fix, not a root-cause solution. Option C (replacing the screen) is unrelated to performance issues. Option D (checking the charging cable) would address charging problems, not runtime behavior. Option F (OS updates) can help but is not among the best two choices for these specific hardware-and-resource symptoms.
