Other manufacturers are already doing this, but Samsung is still lagging behind. Brands like Xiaomi and Oppo have seen battery increases from 500 to 1,000 mAh, with “big” names like Google, Samsung and Apple seeing little change. more possible. Samsung is now considering a big step forward in its batteries, we hear from the industry.
The plan is to switch to stack batteries, which are constructed differently. Xiaomi calls this “stacked-cell battery technology”, which means that you can significantly increase the battery capacity even in your own foldable. Samsung SDI also wants to take this step, Report Korean media.
Samsung has launched the Pilot line and promises more battery performance
Until now, smartphone battery materials have mostly been wrapped. In the new method, however, they are stacked in layers, similar to electric car batteries. Preliminary tests show promising results: energy density can be increased by more than 10%. For users, this means longer runtimes without large and noticeably bulky smartphones.
Samsung SDI currently has plans, but they have not yet been implemented. But since they want to remain the market leader for mobile batteries, the move to stacking technology is probably a foregone conclusion. Example: For a Galaxy S25 with a 5,000 mAh battery, that means at least a 5,500 mAh battery for the Galaxy S26.
Xiaomi and competitors are leading the way
Xiaomi has increased the capacity of some devices to 500 mAh, and the Chinese Redmi Note 14 Pro+ even increased it to over 6,100 mAh. In the first comparison test, it brought the new Xiaomi smartphones to first place. Unfortunately, Xiaomi isn’t bringing new batteries to all models, we still have to wait for the Xiaomi 15 and 15 Ultra.
