Yes, with light usage. Galaxy S25 Ultra (5,000 mAh) and S25+ (4,900 mAh) achieve 1.5–2 days battery life for light users (2–3 hours screen-on time daily, mostly standby). Heavy users (6+ hours screen time, gaming, GPS) drain fully in 1 day. Power Saving Mode extends endurance further. Mid-range Galaxy A55 (5,000 mAh) also delivers 2-day battery for students/light users. Typical daily drivers charge nightly regardless — multi-day battery realistic only for very light usage patterns.
Is 20W charging enough for iPhone?
Adequate but not ideal for busy Malaysians. 20W charges iPhone 15 Pro Max (4,422 mAh) in ~90 minutes (0-100%) or ~30 minutes (0-50%). Acceptable for overnight charging but slow for emergency top-ups during meals/breaks compared to Samsung’s 45W (~60 min full, ~20 min to 50%). For users with predictable charging routines, 20W sufficient. For delivery drivers, content creators, travelers needing fast recovery, 20W frustratingly slow. Apple hasn’t increased charging speed since iPhone 12 (2020) — overdue for upgrade.
