Battery Grapher graphs your historical battery levels and learns your habits to make smart predictions on what your future battery levels will be. Developed specifically with energy consumption in mind, Battery Grapher has almost no impact on battery life.
SMART PREDICTIONS
Battery Grapher uses historical battery levels to intelligently predict what your battery level will be throughout the rest of the day, allowing you to plan when to next charge your device. The longer you have Battery Grapher installed, the more accurate future battery level predictions will be.
LOW ENERGY CONSUMPTION
Battery Grapher is made for people who want to extend the battery life, meaning that low energy usage is a priority. The app runs a background task only once an hour, and doesn't require a network connection, which keeps energy consumption extremely low.
CUSTOMIZABLE NOTIFICATIONS
Battery Grapher allows you to set notifications that fit your needs. You can get the app to notify you when you battery drops below a preset percentage, or if you only have a certain number of hours left before your battery runs out. (currently only available on watchOS)
ALL COMPLICATIONS & WIDGET SIZES SUPPORTED
Battery Grapher supports all complications & widget sizes. Complications can show hours before needing to charge, or battery %. Both complications and widgets are customizable from within the app.

Great Battery App
Have been using this app for some time now. I find it needs a update for the new Apple Watches since apple have change a few things in its software like the dock has been remove it no longer updates the time left. I find the only work around is to hard reset to get it to work. Hopefully a update will fix this problem
Amazing App!!
This app is fantastic, such a cleaver idea! I use it across all my apple products Apple Watch ultra, iPhone mini 13 and my iPad mini 6. I can go by my day stress free knowing how much battery I have left especially when it has learnt my usage behaviour and battery life cycles over a couple months!
Poor Information
The app might of been ok on older iOS versions but on current ones it gives incorrect readings. I am forever having to remove and re install it to work.
Not recommend, sorry
Hands down best battery app
For both iPhone and in particular Apple Watch, see how fast your battery life is being consumed per hour, averages and how many hours you have left. Lots of additional info. Just love this app.
All that’s missing is a manual dark mode for the iPhone app otherwise well worth it!
Almost perfect 😉
Hi Nicholas,
Would it be possible to add the current battery percent charged in the top right of the widget?
Obviously it won’t fit in the smallest size widget, but in the medium and large widget formats there’s plenty of room.
Maybe have a setting to enable it?
I’ll upgrade my rating to ⭐️⭐️⭐️⭐️⭐️ 😛
Another enhancement suggestion which may be more difficult to implement is to expand the history graph in landscape mode, meaning show the graph going back a couple more days than it currently does...
Thanks!

It’s wildly inaccurate
The estimated time until 0% couldn’t be more wrong. 19 hours? I was on 20% yesterday and it said I had 8 hours of usage left. On a 3 year old iPhone X? I don’t think so. Entirely pointless as it doesn’t work.
Latest update
Brilliant app, when hours until 0% is selected with detailed text turned on sometimes the minutes don’t always appear on the Apple Watch complication, just hours appear, seems ok now, the complication is good at showing how much time is left till the watch battery goes flat, the Apples stock battery percentage complication also has a white ring which dissapears when the watch loses charge and comes back to life when charging and charged, please add the white ring to your brilliant app
Neat historical view of battery usage
I saw this app on a YouTube video, with its customisable notifications for remaining time or battery level.
Sadly the video didn’t mention that the app needs to collect data over a couple days, in order to its thing.
The display is easily readable.
The developer responds quickly to feedback.
Great app, starting to get bugs however
This app has been great, but the past week the time no longer updates on the complication, it’s missing huge chunks of data and it says it’s charging for longer than it is.
best battery tracker for the watch!
Invaluable statistics about my watch's battery life and the complication to give you an estimate of battery time remaining is very useful. I am experiencing some bugs where the data doesn't get tracked and it shows the wrong value on the complication, however, that I hope can be ironed out soon!
