India-Specific Battery Tips

Power cut preparedness: A 6000mAh battery at 20% drain per hour (moderate use) gives approximately 4 additional hours during power cuts vs a 4000mAh battery. Plan battery capacity based on your area's typical outage duration.

Heat management: Indian summer heat (38–45°C) accelerates battery degradation. Avoid charging in direct sunlight. Most modern phones have heat management that slows charging above 45°C.

Background apps: Indian OTT apps (JioCinema, Hotstar), WhatsApp, and Instagram are significant battery drains. Use data-saver modes when on battery.
