Hmmm…I don't get it

The other day, I was browsing my friend’s Android phone. I saw an app installed named “Battery Booster”. Interested in how it worked, I opened it. Then one of the preferences caught my eye, it said

battery booster

Security Level</p> Select low level to save more battery, or high level to keep system more stable

I’m guessing that the app would quit other apps that weren’t being used much or were sucking up too much power. While that makes sense to a degree, it’s a scary thought to an iOS developer. One app can quit another?! I wouldn’t want an app quitting a running process for the sake of “saving more battery”.

Another seemingly wasteful function was a low battery light. The phone was on low battery so a white light would glow on the top of the phone. I don’t see any need for this at all. If the phone is on low battery, don’t deplete the reserves even more with a useless light that you cannot turn off!

I’m sure that the makers of the phone intended it to alert users, but I’m sure that I can see the battery bar at the top of the screen.
