  • I did pick the DBrand Kill Switch case (including. skin and screen protector) for both me and my partner. It was on the pricer side, but I’m pretty happy with it. Feels quite good to hold and certainly rugged enough to protect it. The skins also stop us from getting each others decks mixed up.

    As for a dock, I picked up the Anker one and it’s alright. Would have preferred the official one, but everywhere was charging a hefty price for importing it.

    I already had a hefty battery pack for travelling. Haven’t needed it much myself, but my partner recently made good use of it for an international flight.



















  • It’s mostly a power efficiency thing. Before push notifications were the norm, most apps used a polling method. They had the application send a request every X seconds asking “anything new”. There wasn’t coordination between apps, so even every app checked once every 30s, it likely wouldn’t be on the same 30s. This caused the device to wake up a lot and never let it switch into low power mode.

    A push notifications system like FCM or UnifiedPush means only a single application needs to run in the background. It maintains a persistent connection to the push notification service and waits for a message. When it receives one it wakes up the relevant app and passes it the details.


  • The issue lies with Google’s FCM (Firebase Cloud Messaging) system, so it’s not something GrapheneOS can really fix. As far as I know FCM doesn’t offer a way to encrypt notification content. Some apps like Signal work around this by instead of sending the message content, they send a little “wake up” notification. This tells Signal on your phone to wake up and it goes and retrieves the new message.

    If you don’t install Google Play Services, you won’t be impacted. But you’ll also not get notifications for most applications. There is an alternative push notification system called UnifiedPush which allows you to choose any server to handle your notifications (and even self host it). But it does require both the service and the app to support it, so it’s not very wide spread yet.
