Battery Graph Widget tracks the battery level of your device and displays the graph with battery level. Furthermore, it calculates the estimate when the battery will be empty based on your past usage. The graph and the estimates are displayed in the Notification Center as well as in the app. The widget in the Notification Center is not displayed by default. You will have to add it with a few simple steps. Both the graph in the app and in the widget are customizable. You can select the color of the graph, translucency of the graph fill and turn on/off the grid lines. In the widget, you can select one of the these time periods: 1/2 day, 1 day, 2 days or 3 days. In the app, you can select one of the these time periods: 1 day, 1 week or 1 month. You can also use the pinch gesture to set another period. NOTE REGARDING COMPANY DEVICES AND BYOD If you received your device from your company or you use your device as bring-your-own-device (BYOD) at your workplace, there is a higher probability that the battery graph will not be as accurate as you would expect. Company devices and BYOD's usually run software (such as VPN client), that requires additional resources on the device. This might negatively influence the graph accuracy.
Great app but
I wish I gould see a finer and easier to see graph scale. Also some of the settings will not hold when you make changes. But otherwise a very handy tool.
United StatesNot worth the money
I followed all the app's Instructions, yet the best resolution on the graph I can get is one reading every few hours hours
United StatesProvides limited but useful information
Updated review: I wrote a review a while ago and decided to update it. I switched from a 6s to a X and setup the X from a backup using NFC between my two devices. This app retained all the 6s data and data extrapolations just didn't look right; not what I was expecting from a battery over 1100mah larger so it didn't detect the new device. I deleted and reinstalled the program and the data reset (didn't see an option to reset or archive in app oddly enough.) Still can't turn the phone sideways, still don't have times listed at more tick marks, and more than one vertical percentage scale should be present to make it easier to estimate battery charge while zoomed in at a particular time without counting tick marks and trying to use a straight edge over to the only percentage axis. Lack of rotation ability on a device with a 19.5:9 ratio is even more annoying than before with 16:9 because anything over 2-3 days compresses the graph too much to be useful and there is so much room that could be used on the screen in landscape. There has been, and continues to be, a time estimation of time until empty which can get relatively accurate after using the phone for a few days (although I think widget placement still affects polling frequency so keep it near the top if you want more frequent data points) but an estimation of time until charged which I had on my Moto Z Play would be extremely useful as well. I downgraded rating from a four to a three because I think there is room for improvement. And, even though I will look for another battery graph to compare with this and possibly replace it, I still recommend this app. It's fairly simple to use and can give a rough idea of whether or not you need to charge your phone a little before you leave or if you have plenty of time to wait. It could also provide insight into when something went wrong that caused a massive battery drain like from cryptojacking for example.
United StatesBroken on iOS 11
Used to work fine, when widget was top of the list, but now with iOS 11, it shows a straight bar up while charging and a straight down while discharging. It also makes weird estimates of how long the battery would last. Tried to contact the developer, no replies. Once fixed, I'll review my rating.
United StatesHorrible interval for collecting battery percentage
I bought the app today to find out how effective my solar charger was at charging my iPhone 7 Plus battery. I have use my phone throughout the day while it was charging I let it charge by itself, and I also let it charge on my in wall charger. After I plugged in my phone and let it charge in the house, it did reach up to 100% however after I looked at the graph an hour later after using my phone for a little bit it never showed my battery percentage getting above 75%. The refresh interval that it records your battery percentage is not frequent enough to get an accurate reading from the graph.
United StatesJust right
Does exactly what it says, simply, nicely designed. Unobtrusive, negligible extra battery consumption. Well done!
United StatesVery minimal detail in data
This app provides a graph of battery usage, yes. But there is about 4 changes in the slope of the graph per day. It is basically useless. Save your money.
