Hi @Arathorn, the battery drain of that experimental build is certainly noticeable, but not disastrous. In 18 hours on a new Nexus 6p, it's drained the battery 30%. Conversations.IM by comparison had only drained 1%. The next biggest battery drain on that device to Vector, had only taken 3%. I think it's still viable enough for an early release to FDroid for the time being, but with a warning. The fact that you can also turn its background sync on or off, means it's quite fine for the casual reading use case, without notifications one.
