I have 2 bluetooth device, a mouse and keyboard. I understand bluetooth connection should take some time after pairing, in occassion I have to connect them manually. However, they are not updating power statistics. Everytime the device connects the keyboard battery low message will pop up from the top of screen. Any suggestion is helpful for me, thanks!

enter image description here

Here is my system information:

$ uname -a
Linux mouse 5.8.0-59-generic #66~20.04.1-Ubuntu SMP Thu Jun 17 11:14:10 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

And my bluetooth status:

$ sudo service bluetooth status
[sudo] password for tiger:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
