Battery health unknown—If your iPhone battery has been improperly installed or is an unknown third-party part (unsupported by Apple), iOS won’t be able to assess its health and you’ll see this message: “This iPhone is unable to determine battery health. An Apple Authorized Service Provider can service the battery.”


Battery health degraded—When battery health has degraded to the point where swapping a new replacement battery will improve your experience, the following message appears: “Your battery’s health is significantly degraded. An Apple Authorized Service Provider can replace the battery to restore full performance and capacity.”


Normal performance—When the battery supports normal peak performance and the performance management protections have not bee activated, the message reads: “Your battery is currently supporting normal peak performance.”


Throttled performance—If CPU throttling has been applied, you’ll see this message: “This iPhone has experienced an unexpected shutdown because the battery was unable to deliver the necessary peak power. Performance management has been applied to help prevent this from happening again.”


Throttling disabled—Manually disabling performance management as explained in the following section yields the message saying: “This iPhone has experienced an unexpected shutdown because the battery was unable to deliver the necessary peak power. You have manually disabled performance management protections.”


A significantly worn-out battery does not pose a safety problem, but you’ll experience way more aggressive performance smoothing. Again, replacing the battery with an authorized replacement part will restore performance.
