The lag will return after awhile. And don't believe the benchmarks. They're synthetic.

exactly.. i'm still waiting for a microfusion power cell..

The speed matsuru is experiencing isn't so much due to the 1Ghz fixed clock rate in beta 3 but can be attributed towards him/her using both the EXT2 virtual buffer from OCLF and Voodoo's EXT4 formated fs. Now that Voodoo formats the internal SD as EXT4 instead of the slowpoke RFS, buffer writes from the OCLF fix just performs way better.


It's great! But at the expense of battery life. Plus, it's a bug in the Voodoo beta 3 kernel.

Isn't there an OCLF removal tool? I think it's mentioned in the OCLF thread over at XDA.
Before applying Voodoo beta1, I removed RyanZa's lagfix. This was before he made it into the OCLF apk so your removal procedures may be different. And yeah, you may want to flash a newer/better firmware before you do so.

I agree, flashing is a real pain. If you're rooted, you could always use Titanium Backup.

Recommendation as in firmware? I haven't tried that many because I just can't find the time to do so. I've used JM2 and now I am on JM5. Both are ok. Would I say that they're better than stock? Not really, no; simply because my complaints are centered around the lag and GPS - both of which, to my knowledge, have not been conclusively resolved by Samsung. I'm sure there are many here will swear by whatever firmware they're using and can provide better supporting evidence. JM7 or JM8 seems to be ok from what I've read. JM5 is all right for my daily use. I am more concerned with fixing the damn lag.

Yes, Titanium Backup can backup and restore all applications, their data and settings.

Ok, but why?

Mind me asking how did you remove EXT2 without removing OCLF? As I understand it, OCLF creates an EXT2 buffer on top of the regular RFS. It's this buffer that gives OCLF its performance edge.

As for Voodoo, there were reports of devices unable to sleep on beta 1, altho I never personally experienced that problem. On beta 3 the clock rate is locked at 1Ghz but I still had 68% battery remaining after 19 hrs uptime (few phone calls, about 15 SMS, lots of twitter and facebook, EDGE, no Wifi). All in all, it feels a little slower than OCLF provided the EXT2 buffer wasn't being written to RFS. But other than that, it runs like a true champ.

If you know how to use adb, you can simply hook up your phone via USB with debug mode on, and just enter recovery mode thru the adb command. It's easier and works every time.

Which version of voodoo do you have? There's a bug in beta3 that locks your CPU to a constant 1GHz rate.

Voodoo is based off the GPL kernel sources released by Samsung and thus do not include the power management optimizations which the XDA community assumes Samsung has done in their stock kernels.

Disabling Voodoo will not help with your situation as you are still on the custom Voodoo kernel - you are just reverting to RFS instead of EXT4. If you really prefer battery life over the performance gains introduced in Voodoo, you will need to flash back to a stock kernel or be an early adopter of dkcldark's lagfix. I am personally keeping my eye on this particular fix.

It does not extend battery life. It'll just give you a more accurate reading of your battery's actual remaining charge. If your readings are wonky, it may be reported as 20% remaining while in actual fact you have 40% left. Note that, since beta 2 Voodoo lagfix resets (recalibrates) the battery stats.

Stock firmwares are those leaked by www.samsung-firmwares.com that we typically flash via Odin. Although opinions differ, the guys over at XDA generally agree that JM1 (the one released in late August, not the earlier one) or JM8 are the best leaked firmwares of the lot. I'm still on JM5.

12pm - 8am is like 20 hours bro. That's ok what. (why you zzz so long?)

Ok, I agree it's annoying. I've gotten severe power drains during the course of the night as well, but that's usually caused by some rogue app that's using 3G. A couple of things you can do:
1. Check your battery stats, is Android OS chewing up the most resources (20+%)?
2. Check your data usage using 3G watchdog or netcounter. Is data being transfered when you're not using the phone?

I'm on JM5+Voodoo Beta 2. Here's my usage pattern:
1. Wifi off, HSDPA off, EDGE only
2. Gmail + Gtalk constantly on
3. Genie widget updates News and Weather every 6 hours
4. Launcher Pro Facebook widget updates every 3 hours
5. A couple of phone calls no longer than 2 mins each
6. About 5-10 sms
7. Total websurfing about 30 mins
8. No live wallpaper

Phone uptime: 6.5 hours. Unplugged it at 74% this morning, it's now showing 61% remaining.

Ouch. I find that, for me, 3G seems to be the one thing that drains the most power. Not only that, if you're in an area with weak coverage, the phone needs to up its radio power output just to hold on to the weak signal. Just so many factors, it isn't easy to troubleshoot.

The one thing that stands out is your stock firmware. I believe later builds have better power management routines baked in by Samsung. But without an actual changelog, this is pure assumption. Also, Voodoo beta 4 was unbelievably laggy for me hence I reverted to beta 2 - but this is probably just due to my setup.

Yeah, Voodoo is reported to use more power than the stock kernels, but in your case, it seems way more extreme. As mentioned, I am on Voodoo as well and have not noticed much of a power drain. I've dropped 2 percentage points in the last 1 hour 20 mins with no usage; so the power drain is not as aggressive as what you're facing. I'm suspecting it's one of your apps in combination with Voodoo.

As for JuiceDefender, I have that installed as well. I've only enabled it to shut off all data once my battery is less than 15%. Else, it does nothing.

Warranty does not cover wear and tear (or user abuse). Sorry bro.

+999. Agreed.

I don't think anyone here has done it. Why not call up Samsung and get a quotation then share it with us here? Not gonna be cheap i reckon.

Rooting is no big deal. In fact, I'd encourage everyone to do it just so you'll have a 1-to-1 backup of your phone.

To be precise, all apps are installed into internal phone storage which is a pre-allocated 2GB partition of the 16GB internal SD. That's why when you go into Settings -> SD card and phone storage, you will see:
1. External SD card (this is the removable micro SD you can slot into the phone)
2. Internal SD card (13+GB)
3. Internal Phone Storage (2GB)

Nothing other than the official firmware gets installed into the ROM part (or more specifically, it's called NAND)

Also, the filesystem chosen by Samsung for this 2GB partition is the reason why there are lag issues. Hope this clears things up for you.

Some applications (such as the browser and media player) independently control the brightness level. Not setting the brightness back when exiting the application or game, is an oversight of the app developer and has nothing to do with Android. Quit whining, it's no big deal.

Run Quadrant benchmark (get from market). You should be hitting 2000+ or thereabouts. Caveat: don't put too much faith in the score results.
