Battery Health Guide

Battery health, explained simply.

Capacity fades with age and charge cycles. When a device can report it, we show that percentage as part of honest product data — not a medical claim, not a lifespan guarantee.

90%+

Strong daily endurance for most heavy users

Often preferred when you need all-day use

80–89%

Fine for everyday messaging and apps

Common balance of price and stamina

Below 80%

May need more frequent charging

Still usable — confirm what fits your day

What the percentage means. Battery health is the reported maximum capacity versus a new battery when the device can provide a readout.

During inspection we capture that figure when available. Listing values should match the inspected SKU. If a battery is replaced during preparation, that should appear in listing notes when applicable.

How to choose. Compare battery health with price and condition grade (Excelente / Muito Bom / Bom) — not percentage alone. A lower figure can still suit lighter daily use. Need help between two SKUs? Send both product links on WhatsApp.

Android and iOS report capacity differently by brand and OS. We publish what inspection can reliably capture for that unit.

From readout to product page

  1. Capture battery health when the device reports it
  2. Record the value on the inspected SKU
  3. Show the figure on the product page
  4. Shoppers compare health, cosmetics, price, and warranty together
