I’ve been using Franco Kernel Manager for a couple months now. It’s basically a toolkit that lets you supercharge your Android device’s kernel. Basically gives you more control over things like performance and battery life.
There’s a ton of features – you can monitor your battery usage, check charging info, and even flash custom kernel mods without a recovery. It’s got a ton of advanced options but the interface is pretty user-friendly. Took me a bit to figure out all the settings but once I got the hang of it, it’s been great.
Look, if you’re into rooting and kernel tweaking, you’ll probably love this app. It’s not perfect – the ads can get a little annoying if you don’t pay – but overall it does the job really well. Definitely worth checking out if you want to squeeze more out of your Android device.
