Battery Health — What Should It Be?

Battery Health indicates how much of the original battery capacity remains. On a brand-new phone, it is 100%, and it naturally decreases over time.

How to Check (iPhone)

Settings → Battery → Battery Health & Charging → Maximum Capacity.

What Is Considered Good

• 90%+ — Excellent.
• 80–90% — Very good, perfectly sufficient for daily use.
• Below 80% — Apple recommends replacement.

Tips

To prolong battery life, avoid extreme temperatures and constantly keeping the charge at 100%. At US MOBI, we verify the battery health of every device beforehand.
