Ratings and Reviews
Overcharged no more
I downloaded the app after having a panic attack when my refurbished out of warranty iPhone 4s wouldn't charge although registering that it was connected to a valid charging device. I opted to replace the battery as well as my 30pin cord since the in home charging was the source of the failure. The tech advised that overcharging can kill my battery so I downloaded this app because of the alarm feature. I have the free version currently, because I wanted to make sure it would do what I needed in a way I could understand. My only complaint is that my phone seems to indicate full charge for several minutes before the alarm sounds. I'm not sure if I need to turn down the slider or if my preloaded battery indicator isn't calibrated properly. Will continue to monitor. So far so good
Nice interface, notifications don't work.
The reason I downloaded this app was to be notified when battery levels reached an upper level as it charged and a lower level as the battery drained. These features are available in the Settings and the interface to set them are awesome - you can choose VOICE or SOUND to notify you when you reach your preferred upper level which you can set as a percentage battery value (in 5% increments) and also to notify you when a preferred lower level battery % is reached as your battery is drained from regular usage. Unfortunately, it works only when it wants to. Sometimes it does notify you as these levels are reached, sometimes it fails to notify you at all, and at times, it incorrectly notifies you that you have reached a set level even though you haven't (ie. it says you reached a set level of 90% even though you are at 79%). Since this battery level notification feature was the sole reason I downloaded the app, I decided to delete it from my phone (iphone 6) after a little over a month of daily use with terrible results in this respect. I did not use the other features of the app so I cannot comment on that.
Outstanding and free
This is the one to get. It actually runs video and checks websites like Google for an hour or something just ask what your battery can do. Then it’s able to accurately predict how long your battery can do those activities in the future. For example, my phone is at 50% and after the test, it shows that I can do GPS for an hour and a half if I weren’t plugged in. That’s the kind of stuff I need to know. Here’s a nice bonus. It will give you an alarm for Max percentage and charging, and minimum percentage when unplugged. You can sit more than one alarm I have mine set for 80 and 85% with a charging, and 40 and 45%. Some of the other apps charge if you want to sit in the AC minimum alarm. So, this app is better and also most important features are free. You can still pay for Pro, which is a good idea because the developer is obviously great.
