Indonesia’s smartphone market is starting to treat 7,000 mAh batteries as more than just a long-lasting power source. On several recent models, that capacity now comes with reverse charging, turning a phone into an emergency backup for other devices when needed.
That shift is notable because many phones still stay in the 5,000 mAh to 6,000 mAh range. Manufacturers are now pairing larger batteries with faster charging speeds so users do not have to wait too long to refill them.
A bigger battery, plus the ability to share power
The real selling point is not only endurance, but flexibility. With reverse charging, these phones can supply power to accessories or other devices, making them function more like a compact powerbank in daily use.
That combination fits people who stay active throughout the day. Streaming, gaming, navigation, calls, and work tasks are the kinds of activities manufacturers highlight most often when promoting these models.
Five models stand out in Indonesia
Among the devices currently drawing attention, Oppo A6t Pro 5G is one of the most prominent. It launched in Indonesia in late February 2026 with a 7,000 mAh battery and wired reverse charging, and Oppo places the price at Rp 4.7 million.
The company says the phone can play YouTube for up to 18.9 hours, run Mobile Legends: Bang Bang for up to 12 hours, and handle WhatsApp calls for up to 21.7 hours. Its 80W SUPERVOOC charging is claimed to take the battery from 1 percent to 24 percent in 10 minutes and reach full charge in around 64 minutes.
Oppo also says the battery is designed to remain strong for up to five years. After 1,800 charging cycles, capacity is claimed to stay above 80 percent of the original level.
Vivo Y31d Pro follows a similar path with a 7,000 mAh battery and a launch in Indonesia on 13 April. Vivo positions the phone for users with high mobility, including ride-hailing drivers, and sets the price starting at Rp 4.3 million.
The company claims the phone can last up to 14 days in standby mode, play music for 72 hours, and stream video for 44 hours. Even at 10 percent battery, Vivo says it can still be used for navigation for up to 3 hours, while 1 percent battery is said to allow up to 40 minutes of calls.
Realme brings three variants at once
Realme takes a different route by introducing three models together: Realme 16, Realme 16 Pro, and Realme 16 Pro Plus. All three use 7,000 mAh batteries, and all support reverse charging.
The charging speeds differ across the lineup. The Realme 16 Pro duo supports 80W fast charging, while the standard Realme 16 uses 60W charging.
Realme claims the battery capacity is enough for more than 20 hours of video streaming or more than 10 hours of gaming. The Realme 16 series arrived in Indonesia in March 2026 with prices starting at Rp 5 million.
Motorola and Poco push capacity even further
Motorola Edge 70 Fusion also enters the list with a 7,000 mAh battery, and that figure is higher than the global version’s 5,200 mAh. Motorola says the battery can support around 50 hours of normal use on a single charge, while 68W fast charging can add enough power in about 10 minutes for roughly 12 hours of phone use.
Its price in Indonesia is set at Rp 6.5 million. That places it above some of the midrange options, but still within the same growing category of large-battery phones.
Poco X8 Pro Max goes even further. Officially released in Indonesia in early April 2026, it uses an 8,500 mAh silicon-carbon battery, the largest capacity among the five models in this group, and is priced starting at Rp 6.7 million.
Poco says the battery can last up to two days on a single charge. For more specific usage, the phone is claimed to deliver more than 74 hours of calling, more than 16 hours of video calls, and more than 15 hours of mobile gaming.
The device also supports 100W fast charging, with a claimed 50 percent charge in 24 minutes. Its reverse charging output reaches 27W, allowing it to share power with other devices when needed.
The appearance of these phones shows how the battery race is no longer only about endurance. In Indonesia, large-capacity models are increasingly being sold as practical daily devices that can also step in as backup power when another gadget runs low.
