This app practically destroyed my battery. When using the scan and "fix" function, all it's doing is finding out which battery cells are off, then turning them on. A smartphone doesn't keep all of the battery cells on at the same time for a reason. Forcing them all on at the same time causes serious degradation to the battery. I highly recommend not using this app. It's a battery killer. It might seem like your phone has more power at first, but this app will ultimately destroy your battery.

I give it 5 stars because my phone isn't lying to me about the battery like it always does, though the battery still runs down fast due to the battery being swollen long before. Anyway, it works since my phone is, in fact, lasting longer. Edit: I got a new phone and it's lasting far longer than what it usually did before. This app can be trusted.

this app is basically a scam except for the first/main page, which is legit info Android provides to applications about the battery. The health checker is a complete scam, first thing is that Android says my battery is "good" but the health check says it's bad, second it says there's 10+ cells bad in the battery but this is a phone... there's only one cell, tablets and foldables usually have 1 or 2, third an app can't fix a bad battery. Ampere is a more useful tool and gives more info and no ads
