Evening all.

I've made a little app to graph battery charge over a period of time.

So far its only been tested on GSM Hero.

Wouldn't mind a bit of testing, and suggestions.

So far the next things to be added are;

Temperature of battery graphing.
Export of data to CSV etc.




Power graph

comments on here for the moment please.

Hi,

This is a nice idea. I remember a similar app on the Market, but I think it disappeared and can't remember its name.

Here are some recommendations:
- Yeah, battery temperature on the same graph would be great !
- It would be much better with "rounded" X-axis labels. Instead of an arbitrary interval between vertical graduations, you should definitely pick the "next-bigger" choice among these: 1 second, 5 seconds, 10 seconds, 30 seconds, 1 minute, 10 minutes, 30 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 12 hours, 1 day, etc (I don't know if you need to zoom out more than 1 day per graduation).
- Use "zebra style" background color (for example: alternating between black and dark green for each day).
- I haven't tested your app, but please ensure that its power consumption impact is negligible  

Keep up the nice work !

cheers for the comments, all taken on board

power impact is very negligible, if at all. it doesn't actually poll for the data, just grabs the data from logs in memory.

I use an app on the market called 'Battery Graph' which does exactly what you're suggesting. It works fine....
