hey. I'm running 0.3.17 and noticed a big battery drain yesterday, especially when in power saving mode.

ran htop and saw whatsapp-sever and persecute on top of the list (higher than htop and terminal) with some 20+% of CPU (I was sure I made screenshots but they did't save for some reason). in task manager the image was constantly switching between 'connecting' and 'disconnected'.

one more thing that looked weird was TIME+ for whatsapp-sever: 40minutes with a 9-day uptime...

still haven't rebooted or killed the server in case I can help with some tests

(not sure it's relevant but htop shows multiple instances of many processes like pulseaudio, contacts, etc, and whatsapp-server too. dunno how it happened... but 45 minutes of TIME+ seems quite big anyway).
