Samsung's new foldables have major battery health downgrade
Samsung has introduced the Galaxy Z Flip 8 and Z Fold 8 with new silicon-carbon batteries, which generally degrade faster than existing lithium-ion technology. These new batteries only provide 1,200 charging cycles before losing 20% capacity, half the previous rating of 2,000 cycles found in last year's models. This poses long-term concerns despite having increased battery capacity within similar dimensions.
