Hi Everyone!

I just wanted to say that I am on my first AOSP ROM (CM7), and I am adoring it for its battery life and customization! I was very hesitant to leave Sense (I still love Sense's look and feel), but boy was it a great decision!

My stock ROM/kernel and battery got about 6 to 8 hours.

My stock ROM/kernel and extended Sprint battery got about 12 - 16 hours.

My Synergy ROM + More Freedom kernel + extended Sprint battery got about 15 - 20 hours.

My CM7.1 + Tiamat 3.3.7 + extended Sprint battery got about 15 - 20 hours.

My CM7.1 + Savaged Zen (BFS - SBC) currently gets about 50 - 70 hours, depending on usage.

I now charge my phone every 2 to 3 days

.

-I have my governor set to Smartass, through the kernel (not setPCU - took that off with this kernel)

-I have the phone v6 supercharged

-I have it undervolted (-50) via ViperBoy

-I am

not

overclocking or underclocking it through CM7.1 settings. It is at the default 998MHz. I have no lag or issues whatsoever, so I didn't mess with that. If anything I could likely underclock and save more battery. I believe "Smartass" does that for me though.

-I have GPS and WiFi on 24/7, I use the mobile data and Google Maps for when I'm driving, listen to music in my car, send lots of texts daily, play occasional games if time allows, use my phone for an alarm clock nightly, make 3 or 4 phone calls a day... that's my normal usage.

I could not be happier with this setup. I never thought that battery life would be a non-issue for me. It is now the last thought in my mind in regards to my phone. I can go hours and only lose 1% on my battery. I'm not sure if I'm just lucky or what, but this phone is completely "new" to me again, and I have no urge for an upgrade (ICS may whet my appetite soon though...)!

Suggestions for OP

I've tried AOSP (CM based) ROMs in the past, but I've always ended up back with Sense based ROMs just b/c of all the little things you have to tweak with AOSP on EVO 4G.

But recently I decided to take the deep plunge and get it all working (mostly b/c Sense doesn't have a full BT stack, but that's a different discussion). This is a great thread, and I've just got a few other things I've run into you might consider adding or linking to, for those out there making the switch from Sense to AOSP:

GPS fix:

you might want to mention that they do the GPSCLRX fix before leaving Sense and then flash the new drivers after the ROM (the drivers alone didn't work for me).

[Guide] Getting ride of the Phantom Voice Mail Icon (NOT THE TEXT MESSAGE ISSUE)

It works! But I had to wipe data on Phone and Phone Storage as a final step (but maybe it would have gone away on its own, IDK).

[FIX] Wake Issue (Android OS) - Combination of Radio/PRI/NV/Wimax/GPS !Solved!

I thought this was my problem, but it wasn't, but it might be for some - it seems like it might be common enough to mention.

I kept thinking I had some kind of wake lock b/c I was having 10-20% per hour battery drain with my phone screen off! (Tiamat 4.1.0, but no V6, over/underclocking, or vipermod at that point.) Also, cell standby and phone took up 30-45% each. I monitored battery usage and what was running and used some of those system monitor apps, but couldn't find the culprit.

Weeeeeellll, it turns out it was caused by my wimax being left on... I know, duh, right? But with the recent Sense ROMs you can leave wimax on all day w/out significant drain (I was using MikG w/ freedom most recently). Once I turned off wimax I was getting 2-3% per hour. Latest radios in both cases. This was before I started looking into Savagedzen, SetCPU, V6 Supercharger, and Vipermod. Cell standby and phone idle are still the top percents (as opposed to display on Sense), but I guess that's normal on AOSP - it doesn't mean your battery is getting drained.

Anyway, it might be worth mentioning that high wimax battery usage is normal since those coming from Sense might not expect wimax to be the cause of their battery problems. Or is it normal? Should my wimax usage be that high when my phone is on standby?

Didn't mean to go too long, just throwing some roadblocks out there that I ran into.

Big Time Error

First off, thanks for all of these resources - it was the first time I've played around with another kernel. I did everything in your guide and it showed massive improvements in everything - battery was lasting 24+ hours on one charge.

However, last night I threw my phone on the charger before I went to sleep. I had 64% battery when I went to bed and woke up to a dead phone with 0% battery. I tried to just turn it on and it would boot to a "shutting down" screen. Removal of the battery didn't help, letting it "charge" didn't help. I eventually just booted to recovery, ran the FORMAT-ALL.zip and reflashed the kernel and rom again.

Something went terribly wrong, I just have no idea what it was. Even if the phone had been off the charger for the ~6 hours I was asleep, it would not have fallen to complete 0% (especially with how efficient this new set up was).

Do you have any idea what caused it, or how to prevent it in the future?
[EVO 4G General] Green_Arrow:
is it working fine now?
[EVO 4G General] dukeredick421:
Yes it is. Doesn't look like any permanent damage was done. It had to sit on the charger for a little to get the battery back up form 0%, but once I reflashed the rom it was okay. However, I have only flashed the kernel, rom, and gps fix. I didn't do the Vipermod or the script because I'm afraid that's what caused the issue. I don't have any evidence of this though, which is why I posted here - hoping someone had an answer because I would love to add those tweaks back on because they were helping my phone a lot!

Thanks.

I can second this assessment. Deck 1.2.1 with Savage Zen 2.2.1. Best combo of stability and performance.

I will say that I like the way the phone operates with the Savage Zen gov. setting though better than "interactive X". Gives me insane battery life and the phone runs smooth as glass. All Evos are a little different though so maybe this is just my Evo's sweet spot.

MIUI

Thanks Arrow, I have actually had your post Bookmarked in my browser for a few days now :p . Anyway, I do have one question about your guide: you mention that MIUI has the best battery life IYO. I use MIUI as my go-to rom for the last few months and I seem to have terrible battery life with it. Even with all the settings in this thread, I think I was getting better battery with Deck's (again, with all suggestions in this thread). Maybe I'm just being paranoid and it's all in my head? This guide seems catered more to CM/Decks, do you have any extra suggestions for MIUI specifically?

Its a very technical thing. It gives apps more memory to use before the app has to garbage cycle which uses up cpu power.

And we have plenty of memory available.

This should bring a slight increase in performance

:SuperCharger:

1. Open Script Manager and navigate to the root of your Sd card which is where the SuperCharger script should be

2. Run the script as root only. Leave everything else unchanged

3. Choose your scrolling speed options.. you should go fast

4. When the list of options is given, choose either of the aggressive setting. I use the first one

The new updates are making everything kind of confusing.

All the options you get have a bunch of numbers next to them; I'm going to just type out which ones are the ones that I recommend.

[6,8,24,30,40,50] My favorite.

[6,8,25,30,35,35] A bit more aggressive then needed, but still good.

5. After it is done and it goes back to the numbered options, press back and leave the script in background

6. Navigate all the way back to your phone's system files

7. Go into system/etc and then into init.d

8. Run as root and boot the supercharger file in there

9. Reboot[/QUOTE]

[EVO 4G General] Crossrocker:

Yes. Option 2 on old v6 was aggressive. Also, I would like to argue your setup. You said you run savaged zen with smartass, vipermod 75 and no v6?

The problem I have is that undervolting this little does not affect battery life much. Instead of taking off v6, run v6 and put setcpu on conservative. You said in your thread that if you want performance, conservative is not the way to go. The fact is that you don't really need to over clock or anything to play a game. I can bet you that a game will play the same whether conservative or smartass. Performance is a whole different matter, ofcourse.

For your random reboot problem, eliminate viper mod completely and go with my setup.

Compare the battery life and let me know. Chances are, I'm just stupid :P

I have been working to get this guide to work for two days and have been having an issue with the phone shutting off after only a few minutes of running. Here's what I did.

1. Flashed from an old rom (don't remember which)

2. Flashed Sense Based rom (swagged off) and original sense kernel

3. Ran #GPSCLRX#

- here's where it gets weird. It never rebooted after I did that stuff. I had to reboot manually.

4. Followed instructions start to finish. Flashed rom, V6 Supercharger Script, etc.

Now my phone shuts off after like 3 minutes of usage. I haven't even activated the V6 or been able to move any further along.

I'd really like to try this setup but I don't have any idea why I'm shutting off after only a few mins of usage.

I run Tiamat 3.3.7 aka the LEE kernel on Deck's 1.3d, VaelPak GB AOSP preview, & MIUI's latest at 128/499 on smartass, undervolted -100mV total. I have zero lag, stalling, freezing, etc. SetCPU is outdated and it's function, plus many others can now be handled by ROMtoolbox which eliminates the need for init.d scripts which take up to 2 minutes to load after you boot into your ROM.

I can set up *ANY* AOSP ROM on a clean install in less than an hour, & weekly MIUI updates in less than 30 minutes.

Nice guide for the noobs, but a little over complicated, & long winded, IMO.

There are better ways to tweak Sysctl & Oom values without the need for init.d scripts so that your tweaks are applied immediately upon boot. Just saying.

I collaborated with ropodope on this guide for tweaking Sysctl & Oom values: http://vaelek.com/index.php?/topic/...de-v101-111711/page__view__findpost__p__26897

We also use ROMtoolbox for CPU/governor controls, LCD density changes, build.prop tweaks, etc. We're currently using SystemTuner to tweak the SD cache (read ahead) & alter the I/O scheduler to deadline instead of bfq. The results are quite amazing. :)
[EVO 4G General] carhauler1969:
Fyi, smartass is it's own screen off profile, & will yield better battery life overall than conservative, interactive(X), etc. Provided that the rest of your setup is solid, with no conflicts, you can't beat the Tiamat 3.3.7 aka LEE kernel, on the smartass governor in terms of battery life, speed, performance, & overall stability in real world day to day usage of your EVO.
[EVO 4G General] carhauler1969:
I'm not trying to hijack your thread here just offering some input based upon a solid month of testing sysctl & Oom tweaks by myself & ropodope.

The Oom values you're recommending, while they will provide somewhat of a boost in performance, over the long term performance will degrade requiring a reboot & cache wipe, or running a flush script to regain that snappiness. This will be especially true for heavy multitasking situations. The specific values you are recommending are not nearly aggressive enough for true hardcore multitasking, & allow the system to chew through a bunch of memory before the Autokiller starts killing off unneeded apps to recover memory. Here I'll prove it, try these Oom values:

10, 16, 55, 65, 75, & 90

Apply these settings & watch your phone fly!!!

EDIT: check out the guide that ropodope & I wrote about Sysctl & Oom settings, try it, if you like it let me or ropodope know: http://vaelek.com/index.php?/topic/1916-guide-car-o-dopes-supersonic-tweaking-guide-v101-111711/page__view__findpost__p__26897

[EVO 4G General] carhauler1969:
The only governor I know of that has screen off capability other than powersave is smartass. To the best of my knowledge conservative, interactive, interactive x, lag free, userspace, etc. all require a separate screen off profile to be created to help with battery life when the screen is off, to help the device "sleep".

The mistake most people make with smartass is treating it like the other available governors & creating a screen of profile, which creates extreme lag because the phone can't wake up. i.e. smartass + screen off = conflict

I'm probably not the best one to test "in-state" times with SetCPU because I'm usually using my phone like a computer, lol. Like right now, I'm posting this from my phone while sitting next to my laptop. I despise typing with a passion.

However, I'm at home for the holiday weekend, & the phone is idle at night, so I'll give it a whirl. Man I haven't used SetCPU in over 6 months...

Unless you use the custom setting & define your own values. I personally do not use the v6 script, or any other scripts to apply my Oom & Sysctl settings.

I apply everything in ROMtoolbox, no scripts required. Those specific settings are completely custom, developed & tested by ropodope & myself. They are optimized for use with our Sysctl settings for the ultimate in hardcore multitasking on most EVO's.
