What You Need to Know\n\nA battery health score of 87 is generally considered excellent, especially for lithium-ion batteries found in smartphones, laptops, and electric vehicles. This value indicates that the battery retains 87% of its original capacity, meaning it still performs efficiently with minimal degradation. But what does this score really mean for your device’s lifespan and daily use?\n\nIn modern battery performance analysis, health scores above 85 are typically seen as outstanding. Most manufacturers design batteries to maintain above 80% capacity after 500–1,000 charge cycles. A reading of 87 suggests your battery is still handling daily demands effectively—fast boot times, stable power delivery, and minimal heat buildup.\n\n### Understanding Battery Health Scores\n\nBattery health is measured as a percentage, reflecting the remaining capacity compared to when the battery was new. A score near 87 falls well within the healthy range. For context, a healthy battery retains 80–100% of its original capacity, while scores below 70 often signal significant wear requiring monitoring or replacement.\n\nExperts note that modern battery management systems (BMS) automatically adjust charging patterns to preserve capacity. However, frequent fast charging, high operating temperatures, and prolonged deep discharges can accelerate degradation—even from a strong starting point like 87.\n\n### How 87 Compares to Real-World Usage\n\nConsider a smartphone with an 87 health score: users report consistent battery life over two years, with only minor drops in peak performance. Devices under similar conditions—like premium tablets or hybrid vehicles—often exceed 85 after years of use. This consistency underscores that 87 is not only acceptable but strong.\n\nLikewise, electric vehicle owners frequently report 80–90 health scores after five years of ownership, with many batteries still functional beyond the typical 8–10 year lifespan. Environmental factors matter: avoiding extreme heat or cold, using manufacturer charging recommendations, and enabling battery-saving modes all help maintain high scores.\n\n### Supporting Keywords & LSI Terms\n\nRelevant keywords include: battery health score, battery longevity, lithium-ion performance, battery maintenance tips, charging best practices. LSI terms enhance SEO naturally: battery capacity retention, charge cycle impact, thermal stress effects, battery aging factors, power efficiency optimization.\n\n### When 87 Might Signal Concern\n\nWhile 87 is healthy, occasional dips below 85 during heavy use or high temperatures are normal. Persistent scores below 80 warrant closer attention—this may indicate early wear or suboptimal charging habits. Regularly updating firmware and avoiding full discharges prevents accelerated degradation.\n\n### Final Thoughts and Call to Action\n\nA battery health score of 87 reflects strong performance and solid longevity. It means your device is holding up well, even after years of daily use. To preserve this
