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.
Very handy app!
Im the tech for my entire family of 6 and my neighbors. This app is perfect for keeping batteries healthy.
Just install, calibrate device right away (worth the wait), then set alerts for below 40% and above 75%. This can save you from having your phone shut off while you are out and about. One more tip: set your widget to show temperature. Temps going below 50F shorten the run time of phone batteries exponentially, and temps above 80F will kill the capacity even faster. Going out in the summer keep your device out of the sun and never leave in car. In winter keep it closest to your body heat as possible (inner coat pocket etc) unless using in your hand or charging. Charging generates heat so the battery will keep itself warm while its charging. But if its 95F+ or Below 0F you really have to be careful. Sometimes you just have to leave it home or you risk killing it.
