It represents always a straight line going up and then down.. ### 4/5 — No longer functional (fixed) *2026-01-30* This is still advertised on the store yet its core requirement (having a widget for the app) is nonexistent. Update the app or remove it from the store. Edit: although missing from the widget section when originally installed, it seems to now be present & I was successfully able to add it. Not sure what caused it to not show up at first. ### 3/5 — Problem on Ultra 2 watch *2024-10-23, version 2.0.5* On Apple Watch Ultra 2, it is showing a maximum of 18h battery life for a battery at 100%. For this watch Apple is announcing 36h for a full charge. ### 4/5 — Works great but could do with some work *2024-10-10* This app is very smart. It learns your usage patterns and stores this data so that it can accurately predict your battery usage and give you an estimate of the remaining runtime of your phone/watch. It’s very smart. The UI could do with some updating though and the app only seems to update once an hour so sometimes I will look at the app or the widget and it hasn’t updated yet which can be a bit frustrating. I wish it would update more often or at least allow me to force an update when I open the app. I still like this app though because it’s actually pretty smart with the way it learn your usage patterns and I applaud the developer for his smart design. One other thing I would like is for the app to be able to switch from a full power to a low power profile when I put my Apple Watch into low power mode. On full power mode my Apple Watch Ultra can go about 48 hours and on low power mode it can go about 72 hours but when I enable low power mode, the predictions in the app don’t change to reflect the reduced power consumption. It would be cool if the app could identify that I have switched to low power mode and change to a separate data set. I feel like this would be easy enough to do and would increase the usefulness of this app significantly. Currently if I enable low power mode, not only are the predictions wrong but also it will be learning my power consumption in this reduced power state so that when I turn off low power mode, my predictions will be overly optimistic. ### 4/5 — no option for Apple Watch complication *2024-07-09, version 2.0.5* The whole point of me buying this was to use the Apple Watch complication. I’ve reached out to the developer and if I don’t hear back, I’m going to request a refund. ### 2/5 — Some problem with the "% Lost in last hour" *2024-05-17, version 2.0.5* Some problem with the "% Lost in last hour" I wrote u in ur email and iMessage too. I hope to solve for give 5 stars happily. ### 4/5 — Love It! *2024-02-21* I would give the app 5 Stars if it worked on all the devices it is supposed to work. I love this app on my iPhone and iPad, it gives me great insights into my battery health and great metrics to follow as to battery drainage. My experience on my Apple Watch Ultra has been less pleasing. I have uninstalled and reinstalled the app twice in four months but I never get an accuracy measurement greater than bad. I don’t charge my watch every night but it can never get the accuracy level to change. Thanks for a good app for the phone and tablet. I wish the app worked as well on the watch. ### 2/5 — Can’t recommend in 2024, or for watchOS 10 *2023-12-31, version 2.0.5* I would give it a higher rating because the app fills a good niche, it’s nice to get an intelligent estimation of battery life especially for a watch. The average % lost in an hour data point is also good to see if your battery usage is going up for some background issue. The app requires a complication on the watch face or pinning the app in the dock, but the dock has been replaced with the Smart Stack in watchOS 10, and you can’t place the app in Smart Stack currently. Meaning you need to take up precious watch face real estate with a complication for this to work. The graphs are also very buggy. The usage graph doesn’t show anything correctly after a few days of usage for me, if you charge the watch it will show it charging across most of the day. It’s almost like it inverts the usage and it goes up instead of down. The usage habits graph also doesn’t make sense to me. for some reason the baseline usage for each hour is around 5%, as you use the app more it will supposedly get more accurate. It says my accuracy is “good” yet I consistently wear the watch to bed and it says my usage per hour through the night is almost 5%, which definitely isn’t true. Not sure why there is even a baseline at 5% anyway, I feel like it should be a baseline of 0% and you’ll arrive at an accurate average way faster. The app needs an update and then my review would probably be a lot better, until then it isn’t worth the price. ### 5/5 — Great app *2023-04-10* I love being able to see the time until next charge based on my daily habits rather than just battery percentage. On my phone, this app took about a week for it to collect enough data for “Great” accuracy. Keep in mind that this takes longer on the watch: about 3 weeks for me. Regardless, this is a cool and useful app. ### 5/5 — Love this app! *2023-03-20, version 2.0.5* This app is so helpful it is so accurate and I’m so glad I bought it as a one time purchase! ## Most critical reviews (10 lowest-rated) ### 1/5 — Die App ist der reine Absturz *2025-04-13* Die App hat erst funktioniert jedoch zeigt sie mir die Batterie vom Telefon an und nicht von der Apple Watch oder anderen Geräten. Jetzt wo das Handy über Nacht vollständig geladen wurde geht die App nicht mal mehr auf. Die App ist eine Codeverschwendung und ihr Geld nicht wert. ### 1/5 — Nic co warte jest pieniędzy ! *2025-01-29, version 2.0.5* Raczej nie polecam bo nie dowiemy się zbyt wiele od aplikacji o stanie swojej baterii lub jak ją ładować. Zauważyłem że jednak aplikacja pobiera z zegarka znaczną ilość energii co powoduje że on działa znacznie krócej. Poza tym co najgorsze nie pokazuje aktualnego stanu naładowania baterii. Gdy miałem 20 % zacząłem ładować zegarek i gdy miałem już 100 % bo pojawił się sygnał dźwiękowy z zegarka, zdjąłem go i zacząłem nosić na ręku. Gdy spojrzałem na tarczę program Battery Grapfher pokazywał nie 100 % naładowania a 19% tak jakby nawet nastąpił spadek energii. Po kilku minutach i kliknieciach w zegarek nastąpiło odświeżenie danych i pojawiło się 100 % .. Czyli aplikacja nie jest intuicyjna i nie działa dobrze więc nawet te kilka złotych nie jest warte by ją kupić. Zdecydowanie odradzam. W iPhone także zbyt wielu wykresów lub informacji nie uzyskamy. Umówmy się jeśli będziemy ładować baterie pomiędzy 20-80 % to będzie jej kondycja wydłużona. Żadna aplikacja nie pomoże w tym nam… ### 1/5 — 全然動かない *2024-12-21* 購入したけど、どの値も変わらない。なにこれ？ 時間だけしかあってない。最悪。 金返せ ### 1/5 — They don’t work with the Apple Watch Ultra. *2024-09-25* The app was last updated a year ago, which is probably why it doesn’t work with the Apple Watch Ultra. I’ll be requesting a refund. ### 1/5 — Not working since I can’t add the complication *2024-09-19, version 2.0.5* Nice idea but simply not working on Apple Watch with watchOS 11. was a waste of money for me unfortunately ### 1/5 — Doesn’t work *2024-07-30, version 2.0.5* Awful I demand my money back ### 1/5 — Not good *2024-03-26, version 2.0.5* I’m only doing a review on here because you guys software mess up my Apple Watch an now I have to buy another an this is not the 1st time this has happen i downloaded it on to my watches an the same thing keeps happening ### 1/5 — Needs update *2024-03-09, version 2.0.5* This app used to be good. I loved it and it was fairly accurate. Now it’s not accurate and it needs an update. I’ll often charge it to 100% and it says I’m at 20%. The developer doesn’t respond when contacted either. It’s not worth the purchase until it’s updated. ### 1/5 — Wird offenbar nicht weiterentwickelt *2023-11-10* Keine Aktualisierung auf WatchOS10? ### 1/5 — Funktioniert nicht! *2023-08-15* Die App funktioniert angeblich ohne installiertes Widget nicht. Mir wird aber kein Widget angezeigt. Auf der Watch funktioniert die App demzufolge auch nicht. Ist Müll! ## Most praised reviews (10 highest-rated) ### 5/5 — Very accurate and very worth it *2025-03-20, version 2.0.5* Very accurate, I didn’t know an app could get this much data from Apple’s locked down battery telemetry! ### 5/5 — funciona mal *2025-03-12, version 2.0.5* la aplicacion es buenisima y bonita lastima que no la actualicen no funciona muy bien animo desarroyador actualiza ### 5/5 — Won’t open on iPad (iPadOS 17.7.3) *2024-12-12, version 2.0.5* Battery Grapher won’t open on my (very old) iPad Pro 10.5in, but widget still updates. Just a small quirk that doesn’t affect the usability of the app all too much Your app is awesome btw!! ### 5/5 — Great Widget! *2024-11-01* It's very accurate throughout my Apple ecosystem! Please add Watch complication for stacks, that would be very handy. ### 5/5 — It’s great *2024-10-17* It just works on my watch and on my phone. ### 5/5 — Großartig! *2024-05-18* Manchmal fragt man sich, weshalb Apple solche Funktionen nicht selbst entwickelt... Ich liebe die Komplikation für die AppleWatch, sehe immer auf einen Blick, wie viele Stunden Laufzeit verbleiben! Der 24-Stunden-Modus und die wahlweise Anzeige der angezeigten Lade-Stunden für die Komplikation bilden eine gute Grundlage. ### 5/5 — Great App (iPad/iPhone/Apple Watch) *2024-03-08, version 2.0.5* It’s been a 5 star experience on my devices for multiple years, but it does likely need an update for the people with newer products. ### 5/5 — Love this app *2024-03-03* I love this app I’ve been using it all the time especially on my watch because I love knowing when I actually need to charge it I use the complication instead of ever looking at the battery, I do wish there was an actual MacBook app just because I feel like it would be nice to have. ### 5/5 — App is improving *2023-10-10, version 2.0.5* The app has improved greatly from when I originally purchased it, a lot more detailed information given on amount of batter drained per hour. ### 5/5 — Amazing App!! *2023-09-22, version 2.0.5* 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! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
