Battery Grapher

Hello Joshua, Could you add aux function for battery Grapher like notify about percent charge. For example , If I charge my watch and battery charge has reached 80% I’ll get notification about this . Thank you very much ! BR, Eduard.

It’s a best app among others for battery I’ve seen, all work as expected and what i love more is ability to see how much percentage per hour was drawn.

Работает прекрасно, всё что необходимо есть. Спасибо что придумали то, до чего не додумались в Apple. Только локализация оставляет желать лучшего. Английский я понимаю хорошо, но время в формате AM/PM для человека, который живет в 24 формате, кажется излишним

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.

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.

The app is so easy to use and setup, and so accurate. I’ve had it give me as little as 5 minutes warning, allowing me to get full use out of my battery. It’s super accurate and reduces how much I need to charge my devices. I have this as a default app on my watch and iPhone.

I didn’t have an issue with the Series 4 or 6 watches but upgrading the Series 6 to the Ultra, if you have a complication and you set it for 54 hours off the charger, the hours to go until it’s depleted never goes past 47. For this watch, this needs to be fixed. Update: With the version that was released on 01/31/23, it fixes the bug (as in the Release Notes) that caused this. It now displays the proper hours until zero in the complication (goes past 47 on the “Hours until Zero”). All around I’m very happy with the app on an iPhone, an iPad and an Apple Watch.

This app works well on IPhone but is very inaccurate on the Apple Watch. It overestimates how long the battery will last by at least one day. It does not trigger the alarms I have set at 40% and 20%. It has not improved its accuracy in several weeks (currently says ‘bad’). Two emails to the developer have not been answered.

It does one thing and does it really well. However instead of basing the estimation on time until the battery is absolutely dead, it would be extremely helpful to be able to estimate the time before it reaches 20% or such. There is also a display issue, where the text would be partially cut off if the complication is placed at the bottom left or right of the watch face. Perhaps showing H or plain number instead of HRS. can prevent it?

Very impressed so far with the ability to see how many hours of battery I have left on my watch with just a glance at the complication.
