I'm assuming you're referring to the part marked with WTF in your screenshot. The apparent delayed start of charging is likely due to a problem in battery-eye graphing. The way the graphs are currently drawn has major inaccuracies around areas where phone (or the data logging daemon) is turned on or off while connected to charger, or if the percentage goes to zero for a while until the charger is plugged in. I'm looking to fix this for next version of the app.

how hard is that to implement? if it isn't very hard, at least I'd find it very useful
Definitely just plotting the graphs in same view would be rather simple. The problem would be to to somehow scale the y-axis meaningfully (all three values are in different units, and have different scale), and communicating the scaling to user.


For anyone asking for features, please post your feature requests to the tracker at project's garage page rather than (or in addition to) posting them here (You'll need a garage account though):
https://garage.maemo.org/tracker/?group_id=1292

It's much easier for me to manage requests there, instead of looking around for them in the forums :rolleyes:

I know that it´s not accurate but probably you can scale mV and mAh to percentages with their highest and lowest values.

Highest value could be your decision or pull out from devices logs when it reports that battery is full (i do not know if it reports this information somwhere). Lowest values might be bit tricky.

IMO current scales are ok.

the most important point of interest to me would be mV + % to same screen. so if one marks 100% & 4,2V to top and 0% & 3,6V to bottom (as it is for now), one could see causality between percent value announced and voltage announced (and probably make some assumptions about algorithms etc)

but I'll go to garage page right away.

e: done

Battery dies DURING charging!
 
1 Attachment(s)
OK folks has anyone seen this before?

Phone charging overnight then suddenly...whammy at 3am, stops charging and fully drains. Next thing I know I am woken up by the boing noises from the battery dying! :mad:

I thought I was going crazy last time this happened but now it has happened for a second time and battery-eye proved it, has anyone else come across this?

perhaps theres a bug need reporting ?

Feature request:
Could you also provide an option to save the current Graph as an image.
Its very tedious to take two diff screen shots and join them.

Sorry i dont have a garage account.. i will register for one later and post this there too.. :)

Greate app only just downloaded it, waiting for graph to be generated :D

Perhaps if you added:
Bug reports and improvements to Batery-eye
to your signature it would help get the reports to the right place.

hmmm possible but it did charge up to 60ish percent and then rapidly drained on idle, and was untouched for the duration as I was enjoying a nice sleep.

So yes , like in the picture i will add, you can see , with musik it last now longer ...

But what is wonderng me , from 24:00 to 6:00 i turned OFF the WIFI with some extra tool and turned on the OFLINE mode. SO , why !!! he still looses so much energy in 6 hours ??? If i would draw that line , the battary will be empty in 3 days DOING nothing ... i just cant understand it. I turned everything off , the only thing was on is the alarmclock ... so why would a mobile phone, while doing nothing get empty in 3 Days !!!

so here is a screenshot i made in battery eye.

http://img64.imageshack.us/img64/4994/screenshot06.png

The time is what i realy did , you can see it nor 100 % on this picture
1) The battary was full, WIFI OFF and OFFLINE MODE
2)´Alarm, serving 10 m
3)Musik about 30 m nothing else
4) Tunrned OFFLINE MODE OFF and switched to WIFi in the school , used it in the lesson to goole things
5) turned wife off
6) Musik ...
7) Just turned on wifi , and internet , and musik ,and some windows ...
Of course the battery is going to be consumed! the OS is still running as a PC (all be it in power saving mode) the RAM and CPU are still in use etc


All times are GMT. The time now is 21:52.
