At what battery health should a phone or tablet battery be replaced?

Q: At what battery health should a phone or tablet battery be replaced?

Battery health is only a reference, and there is no fixed replacement threshold that suits everyone . Some people find runtime inadequate while health is still above 90%, while others can meet their daily needs after it falls below 80%. When battery health falls below 80% , some devices display a repair or service recommendation. If runtime has clearly shortened, you need frequent top-ups, the device shuts down unexpectedly or daily use is affected, it may be time to consider battery replacement. What to consider Base the decision on actual runtime, device behaviour and your usage . If the battery swells or becomes unusually hot, stop charging and using the device and arrange an inspection promptly.
