Root [KERNEL]SpeedDemon V5.6 (Performance & Battery Improvements) - MIUI Kernel

[Austrie]

Do MIUI have trickle charging, or just CM7? I don't think we have trickle charging, but I think we should be good if we do. I for one always charge over night.

I think both, and stock too, cause I am pretty sure ticker got it to work that way in CM7 because that is how the internal hardware is supposed to work. I am not sure of MIUI, but it is based off the CM7 code for parts of it, possibly this part?

(I could be wrong, I haven't used a 2.2 ROM in ages)

 

[Austrie]

Stock doesn't trickle charge.

 

[agentc13]

I believe this is the quote where he explains it a bit, there might be more discussion at some other point, but this is what I found.

This phone's internal hardware switches to a much lower-output charge at 90% and turns the light green, even though it's not entirely full. If the stats are wrong it will enter this mode with the battery being WELL short of actually being full, and require many hours of additional charging (in some cases as long as overnight!) before it reaches an actual full charge. This is actually a good thing rather than a bad one (contrary to some people's views) as overcharging lithium cells both damages them and can cause overheating (which again can lead to fires!); I like how the Triumph manages the battery although it can easily lead to a situation where you think you have 100% when you really don't, especially if you're swapping batteries or ROMs around, and that in turn leads to surprises when the phone shuts down while you think it has plenty of battery left.

I have used the words trickle charge when talking of this, because that is what it means to me. Correct me if I am wrong.

I also took this to mean that it was the standard behavior for this phone since he was talking about the internal hardware of the phone.

Yes the stock ROM should charge in this way as well as MIUI and CM7. Also increasing the usb draw that high could cause potential problems of overcharging. It's not good to charge lithium batteries to fast. That is why charging on usb port of a computer is better for the life of the battery than an a/c charge because a/c chargers charge at a higher rate, thus shortening the life of the battery. I see no benefits to increasing the usb draw this high. Maybe going from 2 to 10 or something but to 500 mA seems unneeded and possibly dangerous.

So going from 1.8 to 3.0 has made my phone start locking up at stock voltages while at speeds it was 100% stable at while undervolted. Wiped dalvik several times. I'm going to flash back to 1.8 to make sure it's the kernel.

If I want to switch from mock to speed demon do I need to wipe anything else besides the delvik.

Nope just dalvik I was switching back and forth during testing

i'll test it out in a little bit and see how the charging is. i just gotta charge my phone up to 100% before i do. i wanna see if trickle charging still applies from 90-100. i mean a jump from .002 amps to .5 amps is a REALLY drastic jump. i like how b_randon stated it maybe .01 amps would have been sufficient enough. i actually think the charging was fine the way it was. my phone charged in sufficient time and stayed charged very well. personally i wouldn't have changed it, but to each his own.
thanks for the work!!!

edit: but at the same time looking at the wall charger that came with the phone it's output is 850ma so 500ma is still a little lower then what ac charging actually pushes to the phone.

Dude.. 3.0 is friggen awesome.
I'm running it with the voltages you suggested a few posts back.
max 1.21
min 122
SmartassV2
vr

No noticable lag at all.. it's flyin' for me.
Thanks.

 

[Austrie]

Thanks showson!

I had put it at 450 because we have a 1450 battery, but when faster charging is enabled in other ROMs(like CM7 for some supported phones), example, the galaxy s would be set to 500mA, and it has a 1600 battery. So I set it to 450 for us.

 

[bing7625]

never got to test it. passed out yesterday, then almost got in a fight with my neighbor at 1am in the morning last night because he told me i ran over his trash cans. i told him to call the cops if that was the case. it's like dude i did that stuff 10 years ago when i was 17. anyhow i'll attempt my testing today and see how it works out

 

[Mobstergunz]

did the native hotspot fix for cm7 work? and can it be added to miui or is it just a cm7 thing?

 

[Austrie]

I had decided to wait on Isaac but it seems he have stopped development...

WIFI tethering in MIUI has nothing to do with the kernel.

 

[Austrie]

Yeah I found that out, by what TG had said, but I could still add the files outside the kernel in the zip?

 

[PerkinsII]

Looks cool thanks!

 

[poler166]

How much better is hd gaming now ?

 

[Chingling]

So what's the approximate % per hour burn on the battery? I'm thinking of flashing both MIUI and this kernel.

 

[punkmaxx]

Download link for 3.0 seems to be broken......

 

[Austrie]

Try again.

 

[Chingling]

I installed the kernel and noticed it is very fast, but I don't see a improvement in battery life. I am using the values you suggested. Might play with it.

 

[Austrie]

I think you(and me too...) need to recalibrate battery, you could also try to reduce each stock value by 75, in incredicontrol.

ive stopped using incredicontrol i didnt notice any change in battery life just the performance went down but switching from smartassv2 to smartass helped a bit

 

[Chingling]

I've heard a lot about recalibrating the battery. Tickerguy gave a good way to do it, but I don't know where that post is. Does anyone know of the correct way to recalibrate?
I also may try moving the values down by 75 like you suggested and report back.
