How to Check Battery Health on Used Phones Before Buying in Bangladesh

Battery health is one of the most important factors when buying a used phone. A degraded battery means you need to replace it soon, which costs extra money. This guide shows you exactly how to check battery health on used phones before buying in Bangladesh.

Why Battery Health Matters

Battery health indicates how much capacity your battery has retained compared to when it was new. A battery at 100% health holds its original charge. At 80% health, the battery holds 20% less charge. Below 80%, the battery may experience unexpected shutdowns and significantly reduced battery life. Battery replacement in Bangladesh costs 1,500-5,000 BDT depending on the phone model.

How to Check iPhone Battery Health

For iPhones, the easiest way is to go to Settings > Battery > Battery Health. This shows Maximum Capacity percentage. Above 85% is good. 80-85% is acceptable. Below 80% means replacement needed. For older iPhones, you can also check via CoconutBattery app on Mac.

How to Check Android Battery Health

For Android phones, download AccuBattery app from Play Store. Open the app and charge your phone to 100%. The app shows estimated battery capacity. It takes a few charge cycles to get accurate reading. You can also dial *#*#4636#*#* on some phones to see battery info. Samsung phones have built-in battery health check in Settings > Battery and Device Care > Diagnostics.

What Battery Health Percentage Means

90-100% – Excellent. Battery performs like new.

80-89% – Good. Battery still performs well for daily use.
