Would be higher ratings if.....


It would be much higher ratings if people actually understood what this app does. I guess they don’t know that it shows them how much battery power capacity their battery’s life actually holds. (It’s like the Age, the performance, the overall strength)

Example say you charge your phone for hours until it says 100%, Kool you think your battery life has full power of 100%, yeah right! Only if it’s a new battery it will really have that much life. Well anyway my battery’s power shows 83% on this app so when my phone is fully charged to 100%, I know that it’s really ONLY 83% and that’s the highest it will be even when it says 100%. {So in my cast 100% =83%}

Next after months or years go by it will be lower and lower until my phone just dies shortly after fully charging it. I wonder how many people think their phone is broken when really all they needs is a new battery. Get this app so you can know if your battery really only has about 30% life.

Well I hope I explained how the app works . I have no idea why most other battery life apps only estimate how long your able to talk, listen to music, watch videos, snap pictures and browse the internet without having this capacity life feature too. I rather have this app and just take a guess on how long I can surf the web and snap pics.

Good check on battery health


I think some negative reviews are off the mark. It’s not a replacement for your built-in battery meter, which estimates how much life you have left before recharging. This measures how much of a charge your battery can accept. If your battery recharges to near 100% much faster that it used to it doesn’t mean your battery is now super healthy. Instead it means it is only charging to a fraction of its original capacity and needs to be replaced. The fraction left is what this app estimates. It’s not perfect but it’s still very useful. I think everyone should have it, so much so that Apple should have something like this built in to the OS.

iPhone 4s


Not bad for such an old phone. Mine says 68% while phone says 96%. I really can't complain. My phone charges pretty fast and tends to hold it well. Rarely do I have issues. I suspect I will probably get a new phone before I buy a new battery for this one. Though my 4s is just fine so unless I drop it from a sky rise or run over it accidentally with my car it will be a while before I get a new phone. This app says my battery is ' average ' and I've had this phone since it was released. I'm doing pretty good I'd say ... Thanks for the cool app !
