Re: [Announce] bnf - nifty little tool, allowing to have battery info at glance
 

That is not the best for the battery - lipo's like neither being drained nor filled-to-the-brim. IIR, from down to15% and up to 85% capacity would do best, or thereabouts. The relatively short-legs of smartphones make that practically very difficult to do.

Re: [Announce] bnf - nifty little tool, allowing to have battery info at glance
 

IIRC, heavy industry (trains) use 20%-80% thresholds, but it's indeed about same thing. People still have NiCD/NiMH habits of "refreshing" by full charge.discharge, which are totally inappropriate to LiIon family.

It means - sadly for you - that your battery is closer to 800 mAh, than the 1700 mAh suggested in last post ;)

While being (non)calibrated for 1699 mAh, your chip "thinks" it's at 63% left 'till 3000 mV (0 mAh - it calibrates at 3248 mV, which should mean 6% left), but in reality, it is 3425 mV, so *very* close to end of discharge. If you calibrate this time, you will notice lower indicated value (something like 1300 mAh, probably), but you need few more calibration cycles, until you get the real value. As said, I suspect something like 800 mAh, which means very poor battery performance.

@Estel

Could I make a request for bnf.

Feature that run the script to calibrate the battery etc.

Making it easier then it already is :)

Re: [Announce] bnf - nifty little tool, allowing to have battery info at glance
 

IIRC, there is already tool for it (kerio written one?). I haven't implemented this, as I think that artificially "wasting" current misses the point. When you calibrate, you want to use your device as normal as it gets, to have your relative capacity as calibrated value.

f you make current higher than usual, you will get your value rounded down, and during regular usage, you will have to mentally "add" some capacity, when it's down to 6%. The same but reversed, in opposite case. so, IMO, the key is to just - from time to time, when it doesn't require effort - let device discharge to < 3248 mV, after a busy day for device (or few days, as in my case, with ~3300 mAh battery). Once per month, or so (at least once for 32 charging cycles).

Having BME FOSS replacement makes it even easier - you just allow device to gently turn down due to low power, no bme disabling and voltage monitoring (BME replacement ensured, that device will shutdown *after* calibration took place, unless you're pressing it under extreme - like 1A - current draw during end of discharge) things.

Of course, if someone want to volunteer writing a script that matches bnf "architecture" ( ;) ), I'll gladly include it in update, with all credits and kudos - but, myself, I'm not very interested in writing a "forced calibration" script, because, as I said, I think it misses the point of calibration during real-world usage.

What tool is out there? Name?
Reason I asked as I used a method u had posted, but in xterm vdq value was 0.

RE: BME I have 3 options installed - Nokia's BME, Alternative and Dummy. I use the first one.

Re: [Announce] bnf - nifty little tool, allowing to have battery info at glance
 

No idea, it was never put into repos, just a script as attachment "somewhere" on forum. I vaguely recall kerio creating one such script, and something tells me that there was a joerg_rw's version floating around.

Just keep in mind, that if your VDQ was 0 for any_reason, then script wouldn't help you.

As for "3 options installed" - nope, you got it totally wrong. What you're referring to is set of options in Advanced Power Monitor, which let you choose which algorithm to calculate capacity (based on voltage) you want to use - regular Nokia's BME, Alternative graph by dr_frost_dk, or disable it at all (dummy). All three of them are guesswork, not real calibrated capacity provided by chip.

BTW, using BME replacement and battery applet status replacement, you don't need Advanced Power Monitor at all - in such setup it's obolete.

hai estel, can you show me howtos change BNF icon ?
just to please my eyes only :D, i love colour full icon

Re: [Announce] bnf - nifty little tool, allowing to have battery info at glance
 

edit the /usr/share/applications/hildon/bnf.desktop file, and point the ''icon'' to any location with your new icon :)

thank you estel ;)

Re: [Announce] bnf - nifty little tool, allowing to have battery info at glance
 

I really dont understand why it doesnt work for me. I'v searched the forum and its like i'm d only one having this problem. When i type 'bnf' in xterm, I get the message
.Error: Read failed
usr/sbin/bnf-i2c: line 45: syntax error: * 3570 / 20 / 1000
sudo bnf does nothing.
