Quick Stweaks Charging Current Summary

OK, so since I've been asked about charging current, might as well sum it up:

1) Set INPUT current HIGHER than CHARGE current. INPUT is charge plus device usage. Set it at max at what your charger can push (2000mA or so). The higher you set it at, the greater the risk of overloading the charger, causing it to go into thermal shutdown.

3) Since the Note 2 OEM charging rate is defined to be 2.5 hours and its battery capacity is 3100mA, setting CHARGE current at 1400mA is plenty (1400/3100 is 45% per hour).

4) Tick "Ignore unstable power". This puts the charge in manual mode, but like I said, you then need to reduce CHARGE to prevent charger overheating.

In other words, set INPUT to say 1800 to 2000 mA, CHARGE to about 1400mA and tick "Ignore unstable power". That's all there is to it!

---------- Post added at 09:24 AM ---------- Previous post was at 08:45 AM ----------

Ticking "Ignore unstable power" is essential to have any significant effect on the charging rate, otherwise you let the phone control it all. In other words, you can put all the output current you like, the phone will have the last word so to speak. The Note 1 probably doesn't exert that level of control, explains why it doesn't behave the same way. Nothing to do with cables or charger... Try it!
[Galaxy Note II Original Android Development] Formhault:
I see.

On the Note 1, I had only three values to change : AC current, USB current, MISC (dock, I guess) current. 450 -> 1000 miliamps. That's it. It was super simple, you see...

Now, on the Note 2, where I see SDP and CDP and H2So4Cl15Na2... I'm like WHAT SORCERY IS THIS...

Okay. Will try.

DCP input : 2000. DCP charge : 1500.

SDP input : 1500. SDP charge : 1200.

CDP input : 1500. CDP charge : 1200.

Can't wait to get home now :D :silly:

Thanks, but to confusing for me...Using Omega with stock kernel + Triangle Away few month now, everything works fine, after every flash Triangle Away and Dongle working fine to. But because in Samsung stock kernel is bug and problem with Wi-Fi, I have to flash old kernel back every time, after I'm flashing newer version of Omega. So I thought, than if I have to flash kernel anyway, I give trie to custom kernel. And Perseus is cool kernel, works fine etc, but Dongle don't work with it, and Triangle Away don't help with Perseus too. So now I'm back with Omega v18 (great ROM) and older kernel. Not that this older kernel don't work or have any problems, but this problem pisses me off, because I don't think, that this is normal, that I'm forced to flash older stuff with 600 euros device. And once again, this Wi-Fi problem is in Samsung stock kernel, this is nothing to do with Omega, Omega only uses stock kernel. Omega is really good ROM! And if somebody wants to know, what Wi-Fi problem I'm talking about, so here, in Note 2 forum is many topics about that.

But thanks anyway!

Did you actually see a difference connecting to your computer or are you somewhere on the road? I'd be careful playing with the USB ports, they are usually integrated on the motherboard, if you overload them, it's not like replacing a charger!

Unless you're dealing with high power ports

, I wouldn't change those settings!

Anyway, keep me informed, but I'm off and on today
[Galaxy Note II Original Android Development] Formhault:
When I'm on the road, or somewhere with my laptop... I'd rather have one charger (for the laptop), and chargw the phone off the notebook. Of course, I wouldn't exceed 1A, but apparently, the value I set for USB charging needs to be ~200mA higher than the target you wanna set... :/

I still don't get what SDP and CDP are for *exactly* so... I'll need to tinker with them a bit more :)

At work, for example, I only charge off USB, so that'll be helpful. Of course, I'll set the currents to as low as possible, as I'll have a lot of time to charge & to maintain battery life (long term).

Most USB sockets are capable of outputting more than 1 amp, anyway. But if you wanna draw 2 amps from a 1 amp USB socket... that will not work... neither will it cause any damage, for that matter. I don't see how it could :eek:

[Galaxy Note II Original Android Development] Blizzard22:
Well thank you for all the suggestions and information about this subject.

I currently I only use the original charger and I don't use any other chargers so I don't have to change values to prevent overheating the charger. My charger keeps cool even while I watching movies or play games.
[Galaxy Note II Original Android Development] Old faithful:
SDP: your standard USB port

CDP: the new high power USB port, I'm told it's indicated with a little luigjhtning sign beside it. My laptop is 4 years old so I don't have the new port, and I need a y connector for my external USB 3.0 drive otherwise I get errors.

I'd say

some

USB sockets on

newer

laptops; not so on older ones like mine.
[Galaxy Note II Original Android Development] mat9v:
Delete please.
[Galaxy Note II Original Android Development] Old faithful:
True. If you notice a drop in charging rate it would be different. I use this tweak mostly because I often charge while on the road with an aftermarket charger and cable, and it certainly doesn't hurt the OEM charger. I also don't use the OEM cable anymore as it has started after 5 months to become iffy. With my wife's phone, the OEM cable failed after the first month.

[Galaxy Note II Original Android Development] iba21:
If i force the minfreq to an higher level, i see that value will change the current freq..

I tryed to get a bencharn with minfreq at 160 and 533.. in all of 2 case i had the same performance.. sure.. with 533 as minfreq i got an huge battery drain with havy temperature of the back cover

It means it works, but, don't change the time in a state..

I was wandering to see that coz i could know how and what to do to increase the quality of the rom..

Btw i can't change the threadsholds too. I changed those in app, but, the sysfs file is the same.. 75 and 17.. you find the file in the same folder as the other, it calls GPU..

Probably some little bugs never finded

Threshold I can change no problem (in Trickster and sTweaks both)

View attachment 2151687

About benchmark scores and temperatures, the main problem is that GPU overclocking quickly causes triggering thermal protection. I heavily undervolted GPU (I'm lucky in a way that I have some good silicon in there) and I can force it to work stably @ 640, I mean minimum frequency and maximum frequency set to 640. I tried 733 but @1.050V it still would not stay that way and fall back to 533 and even 440 sometimes when CPU was also being used. I think that there are 2 main problems: overheating for one and power distribution - my guess is there are limits to what battery can safely provide for cpu/gpu/screen and when needed gpu and cpu is downclocked.

When my phone is awaken from some time of deep sleep, I can get much higher scores in benchmarks, especially gpu ones. My record benchmarks were just over 20030 in Antutu, 7367 in Quadrant, 4616 in 3DMark and 2314 in Geekbench but those were on some other kernel that allowed OC of 1920 (2000 was never good because cpu would downclock from heat).
[Galaxy Note II Original Android Development] iba21:
Try to force a value upper that 75.. under 75 it worked.. upper not.. :what:

Edit: i don't have a real limit.. sometimes i try to put that value.. and it will not save.. move by 1 numer than the effective saved, and change..

Now i'm at 80 and 18.. cant move anymore.. :what:

What's that for?
[Galaxy Note II Original Android Development] Formhault:
Why? If I lock the GPU to a high freq, and don't allow it to go below 533 or above 640...

The app, whichever it is, will use the GPU on min clock, which I just set as 533...

[Galaxy Note II Original Android Development] frankcilo:
Very incredible this bug in the gpu, I'd never even noticed!

I did several tests, and everything goes at random. Now I was able to set 350MHz as minimal and as the maximum frequency and remains at 350MHz, but if impact other values, it always set to 160MHz only.

Andreilux absolutely must solve this bug, because now in addition to the bug of microphone is also the gpu.

And now I'll explain why this kernel has a lot of lag compared to the other

Guys, do you think it could be set at kernel level the network priority, such as wifi vs data?

Right now wifi dominates data connection, meaning once phone connected to wifi network any internet connections is going through it, regardless if that network has access to the internet or not, which means if the network is without internet then your phone without internet too, even if data connection is active.

It's not clear to me if GPU goes or not to higher frequencies or stick to the lower one. Looking to my time_in_state effectively stays @160 (or @266 if I raise up the lower step), I checked after playing a little with 3d intensive game (real racing 3).

I'd like to play a little with voltages and overclock for gpu (and cpu also). How do you check frequencies steps and how can I make some stability test?

Can I have a little table of good voltages values for gpu and for cpu to start from?

I don't see a problem with that. As far as I know, there are people out there who use a different app than the one provided, so... it's okay :)
[Galaxy Note II Original Android Development] ph03n!x:
Doesn't STweaks get reinstalled at boot if you uninstall it? [MENTION=2663544]Miqueas[/MENTION], it wont do any harm if you do not use it to apply any settings though. And STweaks is better IMHO because the settings get applied even before Android loads, while Trickstermod is app that will execute after Android boots completely.
[Galaxy Note II Original Android Development] mat9v:
It may be a problem with STweaks because if you screw with settings to much you may end up with "unbootable" system and since settings are kept in /data/.perseus you can't just delete them from scard and start from scratch :) On top of that STweaks seems to be unable to set up_threshold/down_differential for GPU while Trickster does it correctly.
[MENTION=447508]GDT[/MENTION] For me, time_in_state is stuck @ the minimum frequency allowed and never show anything else.

There are no "perfect" voltage settings, but for my silicon the following works cool and stable:

54	725

108	750

160	825

266	850

350	900

440	975

533	1025

640	1050

733	1075

800	1125

Use TricksterMod, it's easiest to use. As to the stability testing, choose some benchmark that display some 3D moving scene all the time. Nenamark 2 is easy, but as it's limited @60fps it will not force GPU to work too much. You can try Bonsai Benchmark, common fps for it are about 15-20 so it should put your OC to test :)
[Galaxy Note II Original Android Development] GDT:

It looks like your phone has nothing running in the background, no sync, nothing, probably no apps installed either. So 9 hours of screen time is not that impressive after all.

With 14 accounts with sync on my phone, I could get 8 hours of screen time continuously watching netflix over wifi. However by turning screen on/off all day (aka normal usage) there is no way it can get 8 hours of screen time, it dies in 12-15 hours with 1.5-2 hours of screen time.

My point is, the screen time means nothing, it's all about how you use your phone.

I have some 8 or 9 odd accounts syncing, and I keep getting whatsapp messages and such during the day, which is just screen on, reply, screen off.

What idiocy are U spouting here? GPU is not blocked @ 160 in any way. Try simple Nenamark 2 with GPU min and max values set to 160, then go higher. Even in that simple test you will see the score is changing. The kernel is not writing values correctly to /sys/devices/system/gpu/time_in_state.

Do something productive and check your info before posting, change min gpu frequency in stweaks or trickster, save settings and go back to that file to see that your new min frequency is now registering as used.

I have no external apps controlling sound or LED. Equalizers are off on all the relevant apps.
