[TESTING] SCBS: Improved battery meter system

[jonpry]

I'm not really sure what it takes to get a good model. That is part of the reason for this thread. But i think 3 cycles is more than I have ever done. You should be good to go. I'll be posting a new rootfs shortly that will be able to generate more accurate models.

I'm not nearly as knowledgable about all this as jonpry but I'll take a stab at it.
The way the model works is the more information it has, the better, so you can generate a model today and then generate a model in 3 weeks and the new one will be better than the old one, assuming you used the logs from the whole available time. The important things are that it got charge and discharge at varying levels of battery, make sure you got your battery fairly low before charging it, at least one time.

The speed you use during logging should match the speed you're going to use during use. You are more or less training the app what your battery will do under varying circumstances.

Hmmm... I got the following results after 3 cycles (charged fully under FRX06 OCed at 650mhz, discharged with normally usage: some texting, some voice calls, a lot of browser surfing, some tapatalk, some youtube, a lot of sleeping in between)

cc=0.353938423
cb=115.441281066
rc=0.454638059
re=0.131118549
vf=1.098000000
cf=0312500000
lr=0.000001000
sl=7.535142851
se=0.007000000

Defintely do not resemble anything in the first post. Unfortunately, these values are Latin to me. The most current scbs.log file I have is 803Kb big. I have like 5 other scbs.log files (.1, .2, ..., .6) which I didn't include in the analysis, should I include them also?

Ndno,

Imho those numbers are great. Use them and let us know how it goes.

Thanks... I will do so.

BTW, I like how you have this in the first post Deservingly so

Jonpry for lots of stuff...

Edit: what is the best way to check if my battery meter is accurate besides rebooting to winmo and comparing it against winmo?

[jonpry]

Ndno,

Unfortunately the winmo battery meter is not terribly accurate. Wistilt2 has been doing lots of "reboot to winmo" experiments anyway, and he says it is consistently within 1%. The things that make this a lot better are that:

1. Plugging in the charger won't cause the level to jump 60%
2. 100% should actually be fully charged.
3. zero, its well empty.
4. Heavily loading the phone won't cause a dip of 10%
5. Putting the phone in sleep doesn't make it apparently charge
6. Thing should be fairly linear.

If your charge only goes up to 98% or so, let me know, there is fix for that.

What's the likelyhood of you being able to cordinate with F22/WisTilt to push the required changes to run the apk with the latest development kernel bits/rootfs? I'd imagine that you need both to read the values off battery, and shouldn't interfere if not running the apk. That way you get a good base of guin^H^H^H^Husers and we get to keep the new keymaps etc.

I am working on something with wistilt2 atm. He kind of wants to keep the kernels seperate so that any problems scbs itself can be identified. That being said he is using scbs on his phones and seems to like it. So i'm guessing wistilt2 kernels will be getting scbs added shortly. If F22 wants to integrate my stuff into his rootfs, more power to him.

Thanks. The battery meter does look more accurate now, especially when I use it heavily, there is no drastic dipping as you indicated. Gonna run this longer and apply the latest log file to get an even more accurate model. Yes, my charge only goes up to 97 or 98% before it stops charging; what is the fix your mentioning?

Ndno,

Edit /sdcard/scbs.conf and change Vf to 1.103. Then either reboot the phone or "killall -HUP scbs" What model are you running, ie RHOD100 etc?
