Battery drain on tablet
Discussion
I have a Samsung Tab S6 Lite which I have owned for 3-4 years. I don't use it a great deal - maybe an hour or two a week at most currently. It's a Wi-Fi only tablet, no mobile data going on in the background. I have all the latest Android updates and security updates installed.
As background information: A few years ago I took it on holiday and over the course of a day it managed to lose 100% of battery sitting in a drawer in sleep mode. I thought the battery was generally draining a bit fast and after speaking with support I sent off the Tablet and they apparently did some repair to the wiring.
My tablet is often in sleep mode. It can be surprising to see after turning it on after a few days of no use that I may have lost 20% battery.
I noticed on 5th April that I lost 22% of battery in a day! Looking at the battery settings it's not clear where the battery has seemingly evaporated to!
5th April - 22% battery usage
I put the tablet in flight mode for a few days and monitored it. Sure enough, the tablet would lose 1-2% over the course of a day which I can live with. There is obviously something going on in the background: pinging Wi-Fi / some app or piece of software trying to connect to internet which drains the battery?
I have looked at Accubattery app to see if I can get any more information on what is using my battery. It does not seem very obvious what is utilising my battery life.
As a benchmark, I have a recent example of my battery usage.
6% used in a day is not bad. But the only thing using my battery is Google Services which accounted for 0.1%. Where's the other 5.9% gone?!
Is this normal to have a battery drain of 5% in a day despite the Tablet not being used? Any other suggestions on how I can identify what is using my battery?

Is it spending time somewhere with poor WiFi signal? If it's constantly dropping out and hunting for a new connection it can really hammer the battery.
I have a mesh network and a node in bedroom. The tablet was kept in the bedroom on standby when it lost 22% battery in a day. I would have expected the Wi-Fi signal to be very good in the bedroom, but it is possible the signal was bad and hammered the battery that day. When I keep the tablet in the lounge (where the router is), it loses about 4-6% on average.
