Apple Inc's move on Jan 24 to give iPhone owners information about the health of their batteries reverses the company's longstanding refusal to make such information available directly on iPhones and iPads, even though battery health has long been easy to check on Apple's Mac computers.
Apple said an update to its iOS operating system will show the phone's battery health and recommend whether the battery needs to be replaced. It will also let users turn off a controversial piece of software that slows the phone's performance in some situations when the battery is flagging.
