On older devices with a worse battery, the phone will show that reduced Maximum Capacity, as well as detail any performance slowdowns due to the decreased battery capacity. On devices that have weaker batteries, the Peak Performance Capability will change to read "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." A small blue hyperlink then says "Disable," which lets you manually turn off your iPhone's performance management.
Apple says that the problematic iPhone 7s were sold in China, Hong Kong, Japan, Macao, and the US between September 2016 and February 2018.

At any rate, Business Insider now has more information about the device, and is reporting the things that Apple's first smart-speaker won't be able to do. From the report (condensed): 1. HomePod can't pair with Android phones.
2. HomePod doesn't recognize different people's voices.
3. HomePod can't check your calendar.
4. HomePod doesn't work well with other streaming services besides Apple Music. (Spotify, Tindal, and Pandora users won't be able to use Siri.)
5. HomePod can't hook up to another device using an auxiliary cord.
6. HomePod can't make calls on its own. (In order to make a call using HomePod, you have to dial the person's number on your iPhone, then manually select that the call play through HomePod.)
7. The HomePod version of Siri isn't prepared to answer random questions like Alexa and Google Assistant.
Starting in 2019, the bill would ban the sale of electronics that are designed "in such a way as to prevent reasonable diagnostic or repair functions by an independent repair provider. Preventing reasonable diagnostic or repair functions includes permanently affixing a battery in a manner that makes it difficult or impossible to remove."
