Battery Grapher graphs your Apple Watch's 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 watch. 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 of their Apple Watch, meaning that low energy usage is a priority. The app runs a background task only once an hour, and doesn't require an iPhone or internet connection, which keeps battery 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. ALL COMPLICATIONS SUPPORTED Battery Grapher supports all complications available on the Apple Watch, giving you the flexibility to place your complication wherever you want.



  • Can’t tell if it works.

    By justmeeagainn
    I really have no idea if this app works or not. The numbers it displays show no rhyme or reason. They go up and down or stay put and make no sense. They almost seem randomly generated. When I open the app, the only thing I see is the accuracy is bad. I wrote the dev a question on Reddit and got no reply. I can’t recommend buying this. Hopefully it will improve and won’t have been a waste of money.
  • Not bad so far. One minor ‘issue’/suggestion

    By Mvbenz
    Not bad. I did run into a minor ‘Thing’ that should be looked at. I had to unpair and repair the watch and lost the accuracy history. When I repaired, I told it to do a restore from the last backup but that didn’t help. Now I need to wait for it to relearn before it is more accurate. Can the app be set to backup to the phone once a day with the option to reload the data should you have to repair the device?
  • Useful information about battery

    By BadDomino5
    I like the developer's interest and enthusiasm. This app is nice and displays useful info about my watch charge. For a first release version it works very well. Some room for improvement. I'd like to see the accuracy improve quicker. It went from wildly inaccurate to somewhat close within a few days of use. The app actually tells you how accurate its predictions are. Until the hone in on your usage I'm afraid they aren't much use. Mine has gone from "very bad" to "ok" in about five days. Some improvements I'd like to see are in the complication. I'd like to see both a battery % charge and the calculated time remaining together. Either text % and the "progress bar" as time left or text time left and the progress bar as %. Worth the download. Hoping to see where this app goes in the next few months. Good luck!
  • Helped me @ the Apple Store

    By Duane Williams
    I can’t tell how effective Battery Grapher is at predictions, but it certainly helped me at the Apple Store when my battery indicator was acting weirdly. Basically, for hours on end, my watch appeared to be stuck at 100% charge, although I knew it wasn’t. Then it would suddenly plummet into power reserve mode. I took screen shots of the BG graphs and showed them to the person helping me and he immediately grasped the problem. The BG graphs were a close match to the diagnostics the Apple person ran on the watch and they accepted my watch for repair. It was my second attempt at the Apple Store. The first time I didn’t have the BG evidence and I got no satisfaction.
  • Great app so far!

    By Let's Review
    Great app so far, still gathering data for accuracy. I’ll follow up later if it doesn’t live up to what’s advertised. Best battery features I have seen so far. Review follow up: It’s been almost 24 hrs since I started playing with the app. But I have yet to see any notifications. I first se it for 50% warning, nothing happened. So I tried for 20%, still no notice - it’s at 15% now, and I’m about to put it on the charger. I know an update is days away, keeping the faith. I like the UI overall. I’ll keep my current rate because I like the concept of what the app wants to do. I’ll re-rate the app if the notifications bug doesn’t improve.
  • Has great potential but also an issue for me

    By JimThePCGuy
    Works fine on my 44mm S4 but on my wife’s 40mm S4 I can’t add the complication to any watch face, using the My Watch iPhone app. I can, however, add the complication by editing the watch face directly on the watch. Tried the standard debug things, rebooting, uninstall/reinstall but to no avail.
  • Great find
