India’s smartphone market is witnessing a clear shift towards longer battery life, with several new launches in 2026 signalling what industry observers describe as the beginning of a ‘two-day battery’ era.
Over the past few weeks, smartphone makers across price segments have introduced handsets with significantly larger battery capacities, moving beyond the 5,000mAh standard that dominated the market for years. Devices launched in March are now carrying batteries ranging from 6,300mAh to as high as 10,000mAh, reflecting changing consumer priorities around endurance, gaming and always-on connectivity.
Among the latest examples in India is Xiaomi’s Redmi 15A 5G, launched at ₹12,999, which comes with a 6,300mAh battery. According to the company’s published specifications, the device is capable of “up to two days of usage” on a single charge.
TECNO’s Spark 50 5G, announced on March 27, has gone a step further with a 6,500mAh battery and is being positioned around extended daily usage.
The trend is not limited to entry-level devices. Mid-range and premium smartphones launched globally in March have crossed the 7,000mAh mark, with some models pushing towards 9,000mAh and even 10,000mAh batteries. The Realme Narzo Power, for instance, was launched with a 10,001mAh battery, while several other brands, including POCO and iQOO, have introduced devices in the 7,000mAh to 9,000mAh range.
The move reflects the way smartphone usage in India has evolved. Consumers are increasingly using their phones for video streaming, gaming, mobile payments, navigation, remote work and AI-powered applications, all of which place greater demands on battery life.
Manufacturers appear to be responding directly to this demand. In many recent product announcements, battery capacity has moved from being a secondary specification to a key selling point.
A recent industry analysis noted that “endurance has graduated to a headline feature”, pointing to a broader shift in how brands are positioning devices in 2026.
According to Counterpoint Research, smartphones with battery capacities of 6,000mAh and above accounted for 29% of global smartphone sales in January 2026, up sharply from 10% in January 2025, indicating that larger batteries are rapidly moving into the mainstream. The research firm also noted that the global average smartphone battery capacity reached 5,291mAh in January this year, marking an increase of roughly 4000mAh year-on-year.
Much of this shift is being enabled by silicon-carbon battery technology, which allows handset makers to increase energy density without proportionately increasing the thickness of devices.
The battery push is also being supported by faster charging technologies. Several of the newer models launched this month support charging speeds between 80W and 120W, allowing large batteries to recharge quickly despite their higher capacities. For instance, the Realme Narzo Power supports 80W fast charging, while other large-battery models launched this month offer 100W charging support.
The current wave of launches suggests that smartphone makers are recalibrating product design around that preference.
