Probably it means that your device hasn't sent any battery info.
But I can get battery info using SMS command.
It doesn't mean anything. What protocol are you using? Do you have some message samples from your device?
Protocol is HO2 and here is the sample of SMS
ID:6430041994; GSM signal:strong; GPS signal:sleep; Battery life:87; Operating mode:silent monitoring; tracking:ON.
I need a sample of data that your device sends to the server, not SMS.
I hope this is what you're asking for :)

Unfortunately it's not. I need HEX message from logs.
Okay here it is

As far as I can tell, there is no battery info last message. Not sure about the first two, but those messages are not supported by Traccar at the moment. Do you have protocol documentation for the device?
The Device is RF-V16 and is using HO2 protocol I have seen it on this website it's there under Protocols, is this something about API version 3.10 will upgrading it to 3.11 fix the issue or it's not possible to get that info from this protocol, please confirm me this. Thank you so much your responses.
The documentation that I have (English one) doesn't have anything about that type of messages.
I am unable to get battery level attribute in response even though I have enabled copyAttributes true like this
and the response I get is
