The days have passed when smartphone users had to charge their batteries in the middle of the day to be used enough. When a 5,000mAh battery becomes popular on high-end smartphones, users still want more than that. And the 2025-2026 period is predicted to open the era of "huge batteries" on phones.
According to a source from the reputable leaker Digital Chat Station, by the end of this year, most high-end Android smartphones will be equipped with a 7,000mAh battery.
Some models can even reach 7,500mAh. Currently, the Red Magic 10 Pro for gamers has a 7,050mAh battery. The OnePlus 14 is also rumored to upgrade the battery to 7,000mAh, compared to 6,000mAh in the previous generation.
Honor is said to be the first company to launch an 8,000mAh Power-powered smartphone. However, according to Digital Chat Station, 8,000mAh batteries will appear first in the mid-range segment, before becoming popular on the flagship line.
Notably, Samsung is also considering designing a new S Pen placement on the Galaxy S26 Ultra. The removal of traditional pen Plug ins will give the company more space to upgrade the battery to 7,000mAh - something many Galaxy S Ultra users have long expected.
An important factor that helps increase battery capacity without making the device thicker is the technology of silicon-carbon batteries, replacing traditional lithium-ion batteries. Thanks to the ability of silicon material to store higher energy, smartphone manufacturers can integrate large-capacity batteries in the old thin and light design.
In addition, fast charging technology will also be improved to suit large batteries, supporting 100W wired charging and 50-80W wireless charging. This helps users not have to wait too long even if the phone has a super large battery.
