Battery tracker is a new plugin that seems pretty useful. Gives a chart of tracked battery levels, but more importantly it tracks the average power draw of the different games you run.
Some games draw wildly different amounts of power depending on area/etc, so getting average numbers for your total play session will be really useful for getting real battery use numbers.
To install, you need to first have decky loader installed, and you should find it in the decky store. You don't need to be in the testing branch of the store or anything, just the normal channel.
Nothing can happen using Decky Loader and you don't have to load the bleeding edge plugins if you don't want to. It all up to you which plugins you use. It's one of the most useful tools for the Deck. The plugins you use could be really basic, like helping you change icons on the games, reach menu for Bluetooth without going into settings, getting HowLongToBeat stats on your game info, etc. It's all very handy and extremely easy to set up. YouTube is your friend on this one.
You should also check out CryoUtilities. It's not going to be for you if you don't wanna use third party apps right now. But at least check out his youtube video explaining the tool anyway. You will find it interesting and learn quite a lot even of you don't install the software.
I was daunted by it at first as well when I got my hands on my deck. I didn't want to break anything. But I tried it at some point and can't recommend it enough! There are plenty of good tutorials on YouTube (that take just 5 minutes) and they also made the process of installing easier since when I did it. So if you're on the fence, I'd recommend just to go for it, it's not as techy as you might think.
