Vivasanti: Without dredging! whats everyone flashing?

whats leading the way in custom firmware for the SGSII

Im about to take the plunge and grab one, what would you recomend flashing?

Lite'ning is an abandoned project, but in combination with Ninphetamine 2.0.5 was the best rom I had for battery life. Was also very stable. Nevermind...

Anyway, CheckRom Revolution is very popular on xda at the moment, with a kitchen app to allow easy tweaking with extra mods, apps and themes.

DarkyRom2 is also a great choice. Stable, quick and well supported.

I'm watching Checkrom and may try it out. Been on darkyrom for a while and like its simplicity no frills and speed. Sarky's are bring out a support tool that looks great and should make things easier to do. Having said that there are a multitude of good roms around. Best way is to go to XDA forums and check out threads for roms you are interested in. That way you can get a handle on the good and bad of each one.

Ive been using CheckRom Revolution and it's fairy stable and the kitchen app is quite a nice addition. I have been running Speedmod kernel and so far not very impressed with my battery life - I have yet to get over 3hrs screen time before it dies.

I find the opposite actually; 3.1 with Siyah 2.1b15 is the smoothest I'e ever used, and the battery life is insane - 36 hours off charge, and still on 75% battery!!!

I also formatted by internal SD before flashing, so that may have helped with the speed.

That is truly impressive battery life, i can get 36 hours but the battery is all but dead.

hey nofam, the battery life does seem to be excellent. Can you tell us (me) if you leave your phone on mobile data/wifi during the day.

IIRC you usually have the wifi sleep policy to turn off when in sleep mode. What synchronising/polling do you have running during the day? Do you have email, twitter, facebook etc updating at regular intervals?

Cheers

So the last charge was 9:45 on Wednesday night – currently (11:40am) sitting at 70%:

- Wifi turned on at home in the evenings, but set to sleep when screen off

- All radios running normally during the night (i.e. not switched into airplane mode)

- 3G sync running constantly, but really only Gmail/Weather widget/SMS backup running

- Screen time currently sitting at 28 minutes, so pretty light usage

The key (as always) is that I’ve eliminated anything non-essential that causes wakelocks. The other crucial change to the kernel is that the sleep lock frequency has been lowered dramatically – the idle drain is noticeably better.

Can you point to somewhere where I can find out about what non essential things I can delete? Also is the lower sleep lock inherent in the newer kernal?

Just flashed to checkrom last night, loving the ROM and in-app kitchen. Never been much into themes before, but so easy with this ROM that I could see myself getting into it more!

Most essential apps/services actually don’t cause wakelocks – it’s more the sort of apps like the Samsung Hubs that continually pull background data. Search for Betterbatterystats and CPU Spy; they’re both really handy for monitoring your CPU over a period of time to see what’s preventing your phone from entering Deep Sleep.

And yes, the lower lock frequency was introduced with b15 – it won’t make a difference when using the phone, but does seem to save battery more when in Deep Sleep.

Hi team, after issues getting my SGS2 to boot into CLockworkmod, I finally cracked it last night.

I have some random kernel whose name escapes me.
I have Cyanogenmod 7.1.0.

I want BLN working.

What kernel(s) should I be looking at?

I tried Siyah b14 and it kept freezing up on me with SetCPU so flashed back to Speedmod.
