The way battery sizes are progressing right now, faster charging speeds will become an absolute necessity in the future, so companies like Samsung may need to cave to public demands. We hear rumors that the Samsung Galaxy S26 series will have a quicker charging speed than the Galaxy S25’s 45W input.
Si/C anode batteries are a new technology, at least for smartphones, and they are becoming a standard among premium handsets rather quickly. Leaker @kro_roe on X says that the Galaxy S26 series will forgo the Li-ion battery type as it’s now headed toward obsoletion, and use a Si/C battery instead.
This new battery type has better energy density. That’s why we see huge numbers like 6500mAh or ever 7000mAh among some Chinese phones lately, and it also helps keep the phone thickness within limits. If Samsung still wants to keep an edge, Silicon Carbon anode batteries are a step in the right direction.
Galaxy S26 series will pull ahead of the S25s with a bigger battery, but the 45W charging speed might prove limiting in that case. Considering the Samsung smartphones price across various models, the introduction of 65W fast charging could provide even greater value. The leaker says 65W fast charging is a possibility with the 2026 Galaxy S lineup, an upgrade that we’ve been waiting for years.
65W doesn’t compete with 100W+ on some Chinese phones from Vivo, Oppo, or Xiaomi, but it’s still a win for consumers since Samsung is a majority shareholder in the Android smartphone market. We’ll see how this story progresses in the next few months. For now, we’re more excited about the Galaxy S25 series, which is coming the day after tomorrow at Galaxy Unpacked on January 22nd. Stay tuned!
