Battery
The 5s battery is bad, does Apple replace it free. I heard there was a web sit to check the serial number against free replacement.

There was the 6s unexpected shutdown issue.
iPhone 6s Program for Unexpected Shutdown Issues - Apple Support
Apple has determined that a very small number of iPhone 6s devices may unexpectedly shut down. This is not a safety issue and only affects devices within a limited serial number range that were manufactured between September and October 2015.
If you have experienced this issue, please use the serial number checker below to see if your iPhone 6s is eligible for a battery replacement, free of charge.
