High battery usage #1354

Open Pounii25 opened 9 months ago

Pounii25 commented 9 months ago

I tryed every type of battery profile I have on my Android 13 device but the consumption is very high despite the real usage is close to nothing (under 40 Mb data in the entire month, can't get the day but sure less)

My set up is simple: A peer (as root peer) on my HomeLab, another peer which is my Android phone. I also have custom dns pointing on the route peer but just for my internal domain (seems working fine)

I let the peer connected all the day, at the the end of it the consumption just for the app is more than 30%

My device:

Asus Zenfone 9 Android 13

Might be related to my issue here: #1140. Do you know if you're changing networks?

Do you mean If I change the provider 5g antenna during the day?

Hi @Pounii25! Could you take a test without DNS settings? I would like to localize the root cause of the issue.

Pounii25 commented 9 months ago

Sure! ok now I have disable the DNS forward to my rooting peer. I let the routes enabled, so you can test it separately. I will report here the consumption.

Pounii25 commented 9 months ago

ok after more than 2 hours I can tell you that without DNS forward there is no battery drain at all.

I get a similar issue (battery drain and phone getting hot) when changing from WiFi to 4g and vice versa, from there on the battery drain will continue until I either logout/login or restart the app. So I meant switching network 'type'.

@Pounii25 Thank you for the tests. You said created a DNS setting "just for my internal domain". Could you give me more details about this setting? I would like to setup something similar.

I didn't note that just because i had battery drain all the time, so i can't tell if also swap network can cause it. But I can tell that I note ( but i'm not sure) when you swap from 4g to wifi not all time the vpn still up and working property, maybe is related to what you're talking.

Sure! So, i set the peer in my homelab as routing peer with a specific network range "192.168.8.0/24", then i test with my phone if any call to my internal service ( example 192.168.8.3) was working and it was fine. Then, in my local pi-hole I set some static DNS name for my service (they all point to a reverse proxy for local certificates), in this way i dont have to remember and write every time IP for my service. Last step I set in netbird manager a specific DNS server in my lab, for example 192.168.8.10 and limited it only for a specifi domain, like "private.local". And that is all I've done.

an update: I made some change in my host VM where is running my DNS service. Seems like I was creating a loop (even the dns resolution was effectively working fine). I will monitor for a couple of days, just to be sure.

update: ok I think I got the real problem, a brief introduction to my environment: I have like more or less 10 apps selfhosted behind a proxy (caddy). One of them (Home Assistant) is implemented but turned off because non in usage yet ( my desire to do things right led me to implement it completely before I needed it). Here the point: I have the app on the phone, configured to point on my environment. I note thousands of queries for that in 1 day!! I find it interesting that if I don't have Netbird turned on, I don't suffer from battery drain. It makes me think that if there wasn't a proxy involved, there wouldn't be this problem. Interesting as a dynamic, because it is a fairly common pattern in homelabs.

Update: the issue persist.

It seems like this could be related to a few things. I've experienced this as well and I have a few suspected causes:

Reverse Proxy settings (specifically the time out for either the frontend or the backend... does Netbird send keep-alives of some type?). If the proxy times out, then netbird would need to initiate a reconnect each time possibly reconnecting to every tunnel
Switching networks (roaming between wireless APs or between wifi and mobile networks) - this would cause the same disconnection and require netbird to reconnect all peers
Power saving mode forcing netbird to lose background data connections to "save power"
