  • Overcharged no more Jan 18, 2017

    By Tloi
    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

    Only 3 instead of 5 stars because this app keeps trying to connect to farcebook. WHY??? What business does any app have reporting my activity to farcebook? My business is none of anyone else's, and that applies ESPECIALLY to farcebook.

    The app is okay. Although I know the design capacity of my battery, the app doesn't seem to show that information. Also, the app would be awesome if you can add the feature that shows the "charge holding capacity percentage" (a.k.a. battery health) of the battery after every charge cycle.

  • Very handy app! Jan 5, 2019

    By Bus1ne55
    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.

  • Charge level alert does not work Sep 18, 2019

    By diver864
    My sole need from this app was an alarm that notifies when battery charges up to 80%, and when it discharges to 20%. Part of battery-life preservation routine. It has those settings, however I think it has successfully done it only once. To make sure I was not just missing short notifications, I sat right here with it and watched it charge to go from 74% to 96% without any notification. Perhaps the other functions are helpful to others, so I'm not giving 1 star, but it does not work for my need. Also, when I went to look for a link for feedback/help in the app itself, I could not find one. A shame.

  • Calibration went on and on and on and on Dec 23, 2020

    By rpins
    I don’t know what it was doing to my phone during the 2 1/2 hours of calibration, which was originally estimated to take 1 1/2 hours. But it seemed that every half hour point after that first 1 1/2 hours, it would tell me 29 minutes left. It would reach that goal, then give me another 29 minutes. The last hour was this horrid techno musical 10 to 15 second loop that went on and on for 45 minutes itself. I couldn’t handle it anymore, deleted the horrible app. Save your ears.

  • Too much “improvement” Jun 23, 2020

    By Owen Coffin
    This was a great app before it was wrecked by a recent update. Now, the charge pauses before the battery is full. This is incredibly annoying to the point that I’m looking for a better app.. Just like millions of other people I plug my phone in to charge before I go to bed thinking I’ll have a fully charged phone when I wake up. NOT ANYMORE! I would like an explanation as to what the thought process was that led to wrecking a once great app.

  1. Planning to play games, use the flashlight, watch or even record videos? Know exactly how much time you have left for any possible plans
  2. Easily create customized Voice Alerts & pick exactly when you want to get notified of the battery level
  3. Complete calibration of your device! Lists apps by battery consumption & saves RAM usage for those activities that really matter

  • Outstanding and free Sep 25, 2020

    By Gheery
    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.

    Very good app. It gives information of how long the charging time is, it gives an option to be alerted on what percentage you want your battery to be charge etc. It also gives information whatt apps draining your battery, many other very useful information about our battery, So we can learn our battery behaviour.

  • Fantastic! Feb 11, 2018

    By MarieBee88
    I just transferred back to iPhone about six months ago after several years with windows phone. I had gotten really spoiled with the live tiles, and was delighted to discover that iPhone now has widgets. I decided about a month ago that I wanted a battery widget because I missed my live tile so much. So I downloaded a few, picked the nicest looking, and paid for the upgrade. Not only did it not work as advertised, but I never got a response from the developers! So a couple of days ago I gave up and downloaded every single widget battery app. And this one is perfect. It gives a rough estimate of how much life is left based on usage, the colors are beautiful, AND it’s free. Granted, I’m about to go and see if there’s a “tip” option because I have no issues paying a dollar or two for a well done app. Thank you for quality!!!

  • Cool App Apr 27, 2018

    By dpbrick
    It’s obvious the developers have put a LOT of work into this app. It is very stylish and seems very functional. That being said, I would suggest that for us more technical types, after “calibrating” the phone they should include an updated measure of the battery’s remaining useful life. Specifically, I would like to see it report the milliamperes-hours (mAh) capacity remaining in the battery when at full charge and as compared to what a new battery has. That would make it pretty much the most outstanding killer iPhone battery app out there.

    Application is very nice. Would there be a way to implement alarm notification repeat once selected charge/discharge threshold has been reached or is this already an option that I havent noticed ? Thanks. If so this would be 5 stars in my opinion.

    This is really a cool app. Notification bar battery icon is so cool. It will nice if you add low battery notification/alarm option. Stay happy all the time, take care and stay safe at home.
  • The new version is so much better, but the battery life estimates are still inaccurate Nov 30, 2017

    By Neilax
    The battery life estimates appear to be total guesses, but at least the new version has many nice new features like a chart of battery usage that tells me the battery’s charge level over the course of a day. I’m rating this new version of the app 4 stars, but I would have given the old version only 2 stars because it had very few features.

    I like the app but it has one issue. It closes whenever the charge level reaches 100% . The app also doesn't start automatically when the phone is restarted. I haven't found anything in the settings to stop these things happening.

  • Works Mostly as Advertised May 17, 2020

    By Bad|Timing
    I am new to the iOS ecosystem so I'm not familiar with the limitations placed on battery applications but apparently they are pretty extreme - this app will only reliably provide a battery CHARGING notification if: 1. the app is in the foreground 2. the screen remains unlocked while the App is running (there's an option for this in the App) Given these two requirements I haven't bothered to try testing the DISCHARGING notification. Note that in my original review I couldn't get changes to the widget to show up. Turns out there's a bug that prevents the selection marks from showing in Dark Mode (which is my default). Once I turned off Dark Mode I was able to select the items I wanted to see on the widget. The developer has promised to fix this issue in a future update. There are other things about the application that I think could be improved which account for just a 3 star rating.

  • Works fairly well Jun 16, 2020

    By markkor
    It shows charge rate and discharge rate graph pretty well but the rest isn't great. The alerts for “100% charged” have never come when my phone was close to 100% charged. I just got that notification again now when my battery was actually only 75% charged. It usually gives me the notification at about 85%. It’s frustrating to say the least.

  • Can’t properly alert percentage Jun 13, 2020

    By Tinuviel-Undomiel
    I want to make sure I’m not constantly leaving my fully charged phone on its charger. This app is supposed to alert me when it gets to 100%. It does, but it can’t seem to figure out when it’s actually at 100%. I get messages that it’s at 100% when it’s at 70%. I’ll be holding it in my hand, not on the charger when it pings “Your batter is charged to 100%” I can see for myself it’s not. This needs to be fixed.

  • Does not work Nov 4, 2018

    By JackspotMocho
    This app definitely does not work. Setting configuration is a awesome but when it comes to execution it fails miserably. I tried 3 different phones 6s, 8+, iPad Pro all iOS 12 nothing. So many bugs from constantly not working 85 % of the time to constant alarms even after plugging and unplugged. Just awful. I even gave to pro a try nothing was different. Good thing I got my refund thanks Apple ✌🏽

  • Not reliable. Nov 13, 2020

    By Borat625283
    Got this for the Apple Watch SE because the stock battery app doesn’t have different color options. Doesn’t work almost half the time as a complication. When I look down to check the battery life all I see is an empty circle and a “-1...” in the middle. Not sure what to do to fix this?? Also the apps logo is trash. Looks like a logo from when the App Store first launched.

  • Wrong measurement Sep 28, 2020

    By ugxhnctkbxd
    It can’t measure the level even being on the top of the screen on the full-on display during the charging. It’s “measured” value on the iPhone 3 months old is +10, 15, 20, 25 to the current real level. It shows the big battery icon with the right level equal to the system level, but I get 75, 80, 85 notifications at 72, 73, 74 levels. Why?
