Real-World Usage Scenarios
1. For Students & Office Workers
If your day involves browsing, word processing, attending online meetings, and streaming YouTube lectures:
- 56 Wh → sufficient for 6–8 hours, might require charging mid-day.
- 86 Wh → covers a full day of classes/office without charging, ideal for mobility.
👉 Verdict: 86 Wh better for students who don’t want to carry chargers.
2. For Business Travelers
Travelers value lightweight laptops but also need long-lasting power on flights or during transit.
- 56 Wh → lighter, easier to carry, but risky on long flights.
- 86 Wh → ensures power throughout international flights, even with WiFi and entertainment.
👉 Verdict: 86 Wh is the practical choice for frequent flyers.
3. For Creators & Designers
Creative professionals using apps like Adobe Photoshop, Illustrator, Lightroom, or Premiere Pro will drain batteries fast.
- 56 Wh → struggles to last beyond 4–5 hours under creative workloads.
- 86 Wh → offers 6–7 hours, allowing longer uninterrupted sessions.
👉 Verdict: For creative workflows, 86 Wh is almost mandatory.
4. For Gamers
Gaming is extremely battery-intensive due to high GPU/CPU usage.
- 56 Wh → 2–3 hours of moderate gaming.
- 86 Wh → 3–4.5 hours depending on title and settings.
👉 Verdict: Neither battery is ideal for hardcore gaming (plugging in is better), but 86 Wh still has an edge.
5. For Casual Home Users
