This is exactly what I did. I was going back and forth between LeanKernel and franco.Kernel but right now I am running franco milestone 3 and I can't say anything bad about it. Bought the app to go along with it and running great!

Yeah I like the kernal.. So nice to see when im not using the phone my battery doesnt drain like crazy.. 720am to 10:00 am I only seen a 9% drain with 4g radios on wifi on but just searching cuz i forgot to turn it off as I left the house and gps on... Thats amazing.. I havent messed with the undervolting yet and that probably makes it even better.. I cant imagine it getting better lol.. Stock battery life sucked donkey balls!!!

putting everything else about the kernel and the app aside. I think the audio hacks and color controls, specifically the OMAP4 Gamma make the kernel and the app more than worth it.

Battery life is battery life. The screen is still going to be the biggest user of battery for most people. A well developed kernel will probably only ever offer only marginal battery gain above stock. At least that's been my experience. I've always gotten pretty good overall battery life with Franco's kernel even if it can vary from build to build.

Frano's kernel is by far the best I've used on any device. It's updated regularly, he's responsive to feedback and he does quality work. Those reasons alone make purchasing the app more than an easy choice.

New guy here, I tried flashing Franco from the updater app and now I'm stuck on the boot screen "Google" am I totally screwed?
I had just rooted the phone and I'm trying to flash Franco on the stock build. Thanks.

Well... Problem is his kernels are made for 4.0.3 or higher, lol its good to check that stuff... so if you're on stock 4.0.2 then that's your problem. If you made a backup in recovery you can just restore that, backups include whatever kernel you are running.

To get to recovery pull battery, replace, hold both volumes and power to bootloader, vol down to recovery, power to select recovery.

If you don't have a backup you'll have to either fastboot a compatible kernel or fastboot restore factory images... Both are easy, don't panic, just let me know what the situation is

No back up.. (my DUFUS BAD) I can get into recovery, I also have the Gnextoolrootkit, shouold I use that to flash back to stock? (concerned about the debugging being off) Thanks, this "Fastboot the kernel" seems easier, googling fastboot now, thanks again.
Edit: Well I'm back, HUGE thank you. I think the biggest help was the "DON"T PANIC"

Awesome! Happy you were able to figure it out... And that's the key to this phone.. Don't panic.. Lol.. You are never screwed and just about anything can be fixed

Yeah it's pretty hard to mess up the phone beyond repair...Don't panic is good advice.

Hey all. I've been searching for answer to the question I am going to ask, but I haven't found any reply that would satifsy me. Is it 100% safe to use the generic hotplug option? It doesn't hurt the CPU life/performance etc in any way? Thank you in advance for responses!

Yea it is safe to use. All it does is turn off CPU1 (technically second core of the dual core) while the screen is off and I believe under very minimal loads and then it will activate once it is needed based on processing loads (or if when the screen comes back on). I will help battery life significantly and it wont harm your CPU. Your computer does the same thing, when it is sitting idle it will turn off 1 or 2 cores (depending if you have a dual or quad core) to conserve energy assuming you have energy saver settings. I have had it running for a while now and I haven't had an issue with performance and it wouldn't harm the CPU life cycle at all.

Edit: I honestly don't know why that hot plug doesn't come enabled by default. I have noticed a significant battery life improvement while the phone screen was off for an extended period of time.

Thanks for your explanation. I was a bit concerned about it since if it improves the battery life without affecting performance, why it was not implemented in official Google kernel that came with stock android images (because it wasn't, was it?).

As far I am aware they did not. You need a different kernel (francos) in order to activate it. When hot plug was first released, I remember reading that it was very buggy but now with the many iterations of kernels since it has been much improved and very stable. I have not noticed one problem. Here is another explanation I found credit to RootzWiki ()

Basically if you just enable the hot plug option, it will turn off CPU1 when screen is off but reactivate it when the screen comes back on. If you set the governor to Hotplug (instead of lazy/conservative/ondemand) it will keep that CPU off until it is needed.

**jmiesse134** · 05-05-2012, 09:43 AM

omap4... So if I just leave the settings at default (rgb at 0 and multipliers at 200) should I just only use omap 4 to adjust screen ? Or is this in addition to adjusting the other control settings?

**JkdJedi** · 05-05-2012, 10:37 AM

WHAAAAS UP Fellows!! Gots me Franco.Kernel all set up and what about the STUPID AWESOME Franco Boot Animation!!!

Thanks again fellows I'm just stoked right now, had to do a shout out!

**2defmouze** · 05-05-2012, 11:23 AM

To add to above.. as creccaj said, hotplug is safe. The concept was included in kernel code by Google, just not enabled, the only reason being it can sometimes cause the phone to appear to take an extra half second to a second or so to wake up when you hit the power button.. and the last thing they want is people complaining about slow wake up times even if its helping their battery, lol.

I'm not even going to try it out.
I am just going to buy it.
Why not? It's 2.22 or whatever and seems as though its worth giving it a shot.

**ajgorr** · 05-05-2012, 03:08 PM

First thing I did after flashing franco's kernel was buying the app :-)

So I got this app and have it set to conservative. Went to test it last night and went to bed with 84% and woke up with 51%. Any idea what could be causing this? I had auto sync turned off and screen set to min brightness. Is Juice defender a good app?

Download CPU spy app, it will tell you what are frequencies used by your phone most. When screen is off, it should be in 'Deep Sleep'. Also, there is an app called 'Better Battery Stats' that is able to tell you what applications are causing your kernel wakelocks mostly, and therefore draining your battery.

Hope this helps!

I believe it depends on what governor your on, by default its interactive, you want to be on Ondemand or less for deep sleep to take effect, CPU Spy (like above) is a good app to monitor that.

I'm on interactive and it shows its going to deep sleep

How do you overclock the GPU?

Not sure if you fixed the problem but I saw this just now and thought I would throw in my 2 cents. I had the same issue as you did when I was running Milestone 3 on Liquid 1.35. Had anywhere between a 15-20% battery drain overnight (6-8 hours). I just recently flashed to Nightly 156 running 192 - 1334, hotplug and interactive gov settings with slight undervolt now and I only dropped 5% last night while sleeping.

If you are having issue continually try the 156 kernel, testing battery today for full battery life with those settings to see how I will fare.

If you needed your phone ON over night I can see this being exceptable but if you didn't and just use it as your alarm in the morning then try AIRPLANE mode at night, this should yield you a 2% drain instead. I'm hoping this is the case, bare in mind I'm only 3 days into my Gnex, and luving it, but in my DX days, I said DX days..LOL, this is what helped. (keeping it plugged in maybe)?
