The switch from lithium-ion to silicon-carbon has seen smartphone batteries become progressively larger in 2025. However, we haven't seen the peak yet. Companies have begun to push for phones with a battery capacity of over 10000mAh, and Honor is set to launch one soon.

Larger mobile batteries were more for tablets in the past, but that changed when brands started using silicon-carbon batteries for smartphones. Thanks to higher energy density, smartphone batteries can now be larger, with realme likely to take the record soon.
