If you're wondering how much of the original capacity the battery in your iPhone or iPad has left, this app is perfect for the task. But 4 stars, not 5, because the help screen is pretty inscrutable (on the other hand, the app is simple enough to make a help screen rather superfluous) and because the occasional ads are beyond annoying.

I updated to ios12 I put in a third battery myself because Apple is a nightmare of customer service. I tried to get a replacement they wouldn’t. They said water damage and Virgin sold me a phone like this with 90% battery life. It then went to 87% within 2 days. Snapchat it would drop 30% after chatting for a minute. So, after the update. Of ios12. It asks to be replaced. Bought this battery 4 months ago. I find that hard to believe.

I was excited to see an initial very good report about my 5s battery. However, the next time I checked, it was substantially worse. Since then, even though I’ve removed the app, my battery discharges way faster than before I downloaded the app. Does this thing mess with battery parameters, and if so how do I restore good ones? Is this a virus planter in disguise?

I replaced the battery in my phone and this app was recommended that came with the kit. I thought 1.99 would be worth it. The app does not work and it tells me that I need to replace the battery. The tips were good but I can get free information on the net. Do not waste you money.
