Purism's upcoming Linux phone, the Librem 5, has run into some development delays that have pushed its release back 3 months to April 2019. Due to a flaw in the phone's CPU, the battery drains in less than an hour. Purism is working with the distributor to fix the flaw. In the meantime, dev kits are still scheduled to ship out in October.
