Is 87 Battery Health Good? Expert Insights for 2025

Is 87 Battery Health Good? What Experts Say

Understanding your battery health score—like 87—is key to managing device longevity and performance. In 2025, a battery health of 87 is widely considered excellent, reflecting strong internal condition and reliable power delivery. But what does this number really mean?

What Battery Health Score 87 Actually Means

Battery health is measured as a percentage showing how much capacity remains compared to when the device was new. A score of 87 indicates the battery retains 87% of its original capacity. This level is well above the 80% threshold often used to define ‘good’ health. According to recent testing by Consumer Reports and battery research labs, scores between 85–90 signal minimal degradation—meaning your device should continue performing efficiently for years.

Why 87 Is Considered a Strong Score in Modern Devices

Lithium-ion batteries degrade naturally over time due to charge cycles and environmental factors. A 87 score, particularly in recent smartphones and laptops, suggests minimal wear. Apple and Samsung models with sustained 87+ scores often last 3–4 years with robust daily use. This performance aligns with manufacturer warranties that guarantee 80%+ health after 500 cycles. With improved battery management software in 2025, many devices maintain these high levels longer than earlier generations.

How to Check Your Battery Health Today

Most devices now let you view battery health directly through system settings. On iOS, go to Settings > Battery > Battery Health & Charging. On Android, settings may include Battery Usage or Battery Saver with a health meter. These tools offer real-time insights—look for sustained 87+ scores as a sign of strong battery wellness. Third-party apps like AccuBattery or Battery Monitor provide detailed analytics too, helping you track performance trends.

What Happens If Health Falls Below 85?

Scores under 85 indicate accelerated degradation, meaning shorter runtime and less efficiency. Frequent fast charging, extreme temperatures, and deep discharges speed up wear. If your battery drops below 80%, consider calibrating settings, avoiding full discharges, or contacting support—sometimes firmware updates or battery replacement can restore health.

Practical Tips to Preserve Battery Health

• Avoid exposing your device to temps below 0°C or above 35°C.
  
• Charge between 20% and 80% for optimal cycle life.
  
• Enable battery saver mode during low-use periods.
  
• Regularly update OS and apps to improve power management.
  
• Perform a battery calibration every 2–3 months by fully discharging and recharging to 100%.

A battery health score of 87 is a clear indicator of a well-preserved component, offering reliable performance and extended lifespan. In 2025, leveraging accurate health metrics helps users make informed choices—whether upgrading or maintaining their devices. Don’t overlook this simple yet powerful indicator: your battery’s health score speaks volumes about its future—and your device’s reliability.
