Battery Analyzer


This widget lets you check your battery usage over time and displays the autonomy based on recorded consumption.</p><p></p><p>Currently, discharge rate is based on past couple weeks. Discharge rate is only calculated on recorded data. Data is recorded only after the widget was started once. The widget will record data even if it is closed (but not uninstalled).</p><p></p><p>It will take a few hours or days before the widget can display any data. </p>

What’s New

1.0.1 Reduce sample rate from 5 mins to 60 mins to lower battery consumption impact. Removed debug text at the bottom.

To start with: Best battery app in store! Only thing I'm missing is a horizontal scale to indicate days. I never can say exactly: my watch consumed e.g. 60% in 10 days. Without scale only rough estimates possible.

So missing this on my 6x . Please mae it avaiable

I think this is the best battery app in the store and I look forward, the overlay being removed. The overlay on Forerunner 735 disturbs is a little bit when reading the data.

please also for the Fenix ​​6x implement

As it runs in background what is battery usage by this app? It affect much battery life?

July 10, 2019 | Version 1.0.1-upd6

Indicates Discharge 0%/day since a few days ago (but % OK) Reinstall, restart and so on: no more estimation. Bug?

Doesn't work correctly on fenix 5x beta 9.71

Good widget. I found a problem with it. I estimated that my watch (descent Mk1) waste 7% every day, and the calculated value on the widget has 10% always. If I use more battery and I waste more than 10% then it increase correctly, but never decress less than 10% it's seems like the scalated range it's fixed in 10%. Please correct it. Thanks

A very good app we absolutely need! It just has one problem, as i see it - it deletes all history each time it's updated - UPS!!! Please fix asap

It is very good app, i have a little problem with it, it doesnt reset when i recharge the watch so it gives me a underestimate for the remaining battery and a overestimation of the lasted.

Hi Baldroega, Thanks for your feedback! The way I designed the estimated consumption (which feeds into all data displayed) is based on past experience. There is no time limit, but data further out in the past get less weight, and data close to the present get high weight in the calculation. As a result, when you recharge the app, it will display the estimated consumption based on past experience. (Otherwise, how would it know the expected consumption for the future for your specific watch and your specific use?)

Amazing app, we needed something like this! Working on Fenix 5X

September 25, 2017 | Version 1.0.0

Excellent implementation. I had it on my to do list to create an app like this but now I can just use yours ;) (On the 735xt the text at the bottom is overlaying each other so you might need to finetune that a bit)

Great app
