Battery testing methodologies can differ significantly; however, CNET utilized a structured procedure for their evaluation. The test incorporated a three-hour streaming video component paired with a 45-minute detailed stress test, starting with fully charged batteries. The goal was to determine remaining battery percentage post-test, with an emphasis on achieving the highest results possible.
CNET specified that their 45-minute stress test included streaming videos, making video calls, gaming, and social media browsing to create a realistic representation of everyday usage.
