[Galaxy S I9000 Q&A, Help & Troubleshooting] prembox:
Quadrant Scores are nothing buddy!!! User experience on how snappy the phone is and how smooth the animations are flowin.....that's what counts!!!

Replace touchwiz with either GoLauncher or Zeam...these are the best as per me...:)
[Galaxy S I9000 Q&A, Help & Troubleshooting] prembox:
when will all the folks gonna get out of the Level 0...that is Kies Update...how to do it... how to hack n do it...lol...............product code et al..... get ODIN folks...visit samfirmware.com... and pick your stuff n flash.... :p
[Galaxy S I9000 Q&A, Help & Troubleshooting] JJEgan:
But that is not official firmware that came with the phone and not using official firmware invalidates warranty . So users choice and users ask for original firmware not stock rom .

Of course all us really clever users who understand Odin hacking Flashing and building all have a back up of the original rom to recover . Dont you .

[Galaxy S I9000 Q&A, Help & Troubleshooting] zizo-88:
Sorry if this had been discussed somewhere else but what kernels, roms, or settings using set cpu or voltage control or whatever should i use to get the 2000+ quadrant score ive been dreaming of... The best i got was 1895.. Im on RYAN OCLF and i overlocked it to 1.2 ghz... Im on stock 2.2 and on the voodoo kernel.. Please post your scores and combinations so i can try them all :-D
[Galaxy S I9000 Q&A, Help & Troubleshooting] PAGOT:
My best: 2520

Deodexed JVK 2.3.3, CF-Root-XX_OXA_JVK-v3.1-CWM3RFS

Tweaks: RAM,SD,I/O,Kernel,VM,Media,Touchscreen

/system ext4/dbdata ext4/data ext4/cache ext4

no OC/UV

And if you are dreaming of quadrant score, then you are in trouble :)
[Galaxy S I9000 Q&A, Help & Troubleshooting] zizo-88:
Dont want to sound like a noob but i really dont get what u wrote here :-P can u bare with me and explain?
[Galaxy S I9000 Q&A, Help & Troubleshooting] PAGOT:
Basically to get a better score as you have now is to install gingerbread(stock is fine, doesnt have to be deodexed) rom + CF root kernel. Enable its tweaks in the Tweak app. Convert to ext4. Thats it. Before you do , you know the drill. Backup, unlagfix, and you have been warned, when you mess up its on you :)

The corresponding links to these parts are in my signature first row I think :)
[Galaxy S I9000 Q&A, Help & Troubleshooting] branalvere:
Please. Quad scores are pointless.

For example : a drag car can hit 250 MPH in 6 seconds, but its not very useful for taking the kids to school.

The only value of quad etc scores is to measure the effect of changes/ mods to your own device. If quad scores were important we would all own LG optimus 2s, wouldn't we?

The real test is how long you can run dungeon defenders before your phone melts!

Oh btw my best quad score was 2300 ish running MIUI RC4 overclocked and undervolted. I could have increased the score by forcing the CPU to run at 1.3 ghz all the time, changing the governor settings, closing all apps and services and blasting nitrous oxide through the air intake but I didn't bother.
[Galaxy S I9000 Q&A, Help & Troubleshooting] zizo-88:
Overlocked and undervolted to how much ?

I got the idea but it's nice to have the highest score among my friends :p
[Galaxy S I9000 Q&A, Help & Troubleshooting] dcarr622:
You can easily get over 3000 with an ext2 loopback ontop of ext4 plus an overclock. But that's beside the point.

What matters is how it feels and performs day to day, that's more personal opinion. Quadrant is virtually useless IMO.

If you want a "true" quadrant score for what the Galaxy S is capable of without cheating/overclocking, you're probably looking at between 1600-1800 depending on ROM and filesystem.

If you are doing this just to impress your friends...well I don't know who that reflects badly upon, you, your friends, or both. Seriously, give it up, or just resort to comparing d!ck size.
[Galaxy S I9000 Q&A, Help & Troubleshooting] nwsk:
These 2000+ quadrant scores are obtained by abusing the way the thing is tested; changing the file system and setting a loop fools the program into thinking the phone is faster than it is. There are people who've hit quadrant scores of 5000+ just by messing with this filesystem thing, with no real performance difference.

In short: Don't bother with it.
[Galaxy S I9000 Q&A, Help & Troubleshooting] bududroid:
Quadrant Score isnt representatove point performance

This My HTC HD2 with my build adreno2D3D driver project but its just little boost on real graphic performance and with quadrant it will show this :D so not only I/O partically error benchmark
[Galaxy S I9000 Q&A, Help & Troubleshooting] dcarr622:
How many examples do we need that Quadrant is not very accurate/useful :)
[HD2 Android Q&A, Help & Troubleshooting and Genera] light_n_roses:
HI !

I have tried many different rom of android now but I have experience on all a very slow download speed from the market ( on wifi of coure ).

I have full bandwith but I download at very low speed ( something like 10 kb/s ) ..is there any reason for this ?
[HD2 Android Q&A, Help & Troubleshooting and Genera] powerdedo:
full bandwidth =Xmbps or Xkbps?
[HD2 Android Q&A, Help & Troubleshooting and Genera] light_n_roses:
well my band with the pc is 1,00 MB/s or 10XX kbps ...anyway I download rfom the market at 10 kb/s ...too slow !!
[EVO 4G General] ECrispy:
Define 15+ hours of heavy use. If the phone is on for most of that time and using data, then JD is not going to be doing much is it?

Your tips are well written - a good starting point for someone new.
[EVO 4G General] goodboynyc:
What bothers me is people say "I got X hours on Y type of usage." Without specifying what battery they're using.

Good read though.
[EVO 4G General] bjb_nyj101:
Obviously, you should that someone is talking about the stock battery unless otherwise noted.
[EVO 4G General] jalai:
you should reset the title for HTC EVO Best Practices for Battery Management on AOSP ROM's.

instructions are a little biased.
[EVO 4G General] twiz0r:
maybe he didn't think sense users deserved attention? ;)

Definitely I good starting point. I would recommend tasker over jd, but that's just me

Swyped from my cyanogenized and gingerbreaded EVO
[EVO 4G General] fr0st420:
Step 11. Get a kernel with SBC for maximum battery life!
[EVO 4G General] knowledge561:
I found this useful. I knew everything else but it introduced me to the battery calibration app and lowering my voltages.
[EVO 4G General] Madvillebuck:
would these instructions be applicable to someone using an extended battery? If so, should the battery life be extended in that scenario?
[EVO 4G General] NYG27:
Sorry, I just signed up to this site and this was my first post. I've edited my original post above to reflect what my definition of 15+ hours of heavy use was and give a detailed breakdown.

I edited my original post to detail that I'm using just the stock battery that came with the phone. I also added the specs of my phone for those that were interested in what ROM and Kernel I was running during these tests after I did all 10 steps.

Good ideal, I just edited the subject.

Meant no disrespect to any sense ROM users. :D

I'll be testing a few sense ROMs next weekend, I'll do a similar post once I've tweaked these steps to fit sense ROMs I'll upload and do some more battery tests.
[EVO 4G General] NYG27:
Thanks for the feedback, that's exactly what I'm looking for. As I want to best tweak these Best Practices for Battery Management on AOSP ROMs as much as possible. I'll test out tasker compared to juice defender to see if it'll help my battery life.
[EVO 4G General] deathsled:
another good tip would be to spell AOSP correctly. What the hell is ASOP? a fable?

if you can't remember how to spell it, here's a tip:

Android Open Source Project
[EVO 4G General] NYG27:
LOL.....great tip, that's what I get for trying to edit my posts quickly.
[EVO 4G General] NYG27:
As long as your running an AOSP ROM like CM7 or MIUI, these instructions would be applicable to anyone, including those using an extended battery.

Since I don't have an extended battery, I'd love to hear feedback on performance from anyone who tried all these steps on an extended battery.
[EVO 4G General] jstalford:
Are you sure you're not already using an SBC kernel? SZ are SBC unless you specifically download the non SBC version. Also, kernel performance is phone dependent. Some people may see better battery life on the stock kernel or Tiamat (AOSP).
[EVO 4G General] Pivo187:
Which kernal should i get for improved battery performance? Im on Destroyer v2 mod & battery drains fast...Link would help to kernal!
[EVO 4G General] HipKat:
Maybe I think too logically, but wouldn't all those apps you say to d/l be using battery to run in the background??

No offense, but I get excellent battery life just by keeping data off when I'm not using it.
[EVO 4G General] NYG27:
Reason I mentioned “SavagedZen-1.1.0-CFS-HAVS-WiMAX-GB-signed.zip” as the kernel to download, is that I've read about and tested that kernel to be more stable. (Maybe just my personal preference).

By all means test out the BFS kernel and see if you get better performance. There are also none non-SBC kernel but I haven't tested them out yet.

I try to flash a different ROM and kernel each week and test them out. As I do, I'm going to update my original post as much as possible to try to get a true Best Practices for Battery Management for both AOSP and Sense ROMs. So far I've only tested these steps with CM7 and MIUI, which is why I only caution people to test these steps with those ROMs or other aosp roms. The more testing I do with sense roms, I'll update my original post on this thread to be compatible with both aosp and sense roms.
[EVO 4G General] NYG27:
If you look at Battery Settings\Battery Use, those apps hardly take up 1-2% of my battery running in the background. That's a trade off I'll take for having them improve the overall performance of my battery.

No offense taken. Although truth be told about your comment, you have listed in your sig that you use the Sedio Extended battery 3500 mAh. If I had an extended battery and kept data off when I'm not using it, I'd have great battery life also. Although I don't like the look and the bulkier feel of the extended battery (no offense, just my personal preference).

That's why I created this thread to help people extend the life of their stock battery that came with the EVO.
[EVO 4G General] r916:
Tiamat>SZ for battery life.
[EVO 4G General] HipKat:
The added bulk is something to consider, but I started doing my "routine" on a stock battery and was getting great battery life, too. The extended battery of course makes it that much better.
[EVO 4G General] NYG27:
Would you mind sharing what your "routine" consists of? I'd love to hear about other people's "cocktail" mixes or "routine" they do to improve their battery life so that I can try it out also. By no means is my original post on this thread complete. I'd love to keep updating and tweaking it to try to get it as refined as possible.
[EVO 4G General] NYG27:
I replied back to you in the PM you sent me. Although since then I've been checking out Destroyer v2 ROM in more detail and it's really growing on me. There is a few more things I'm tweaking in my MIUI ROM right now but in a few days I'm going to flash Destroyer v2. I'll let you know how the battery life performs once I'm done testing it out.
[EVO 4G General] HipKat:
1 - The "HTC Method w/10 Time Unplug"

Charge to full, unplug, turn off the phone, charge while off for another hour. Unplug, turn the phone on for 2 minutes, turn it off again, charge for another hour.

Unplug til the light goes off, plug back in til it turns green.

Do that 10 times.

Boot to Recovery, while plugged in. Clear battery stats, boot to system. And wait 2 mins, THEN unplug.

Also, I keep my GPS, mobile data and WiFi off unless I need it. You don't need either of those to make phone calls or texts
[EVO 4G General] shoobshoober:
i find it REALLY hard to believe that you can manage that much screen on time on a stock battery (5+ hours of screen on??).

great tutorial though for those that need it. i may try it out next week to see if i can improve my battery life with your exact setup.

also i dont know if anyone said this since i skimmed through the thread but battery monitor widget can track everything as well as wipe batt stats. pretty useful
[EVO 4G General] potna:
Good post. Way to be tough skinned and optimistic when dealing with this tough crowd.

I may be back to see if I have missed anything.
[EVO 4G General] monkeybone12:
Superb writeup!

I've been playing with MIUI for months now, and I've never heard of the VM heap tool. Thanks for the info!

BTW - I'm having STELLAR battery life on Timats 3.3.7 with MIUI 4.15 on 0004 Hardware. Seidio 1750mah battery too.
[EVO 4G General] patelkedar91:
I don't do half the things you listed.

I just got MIUI's ROM... never worried about battery life ever again.

But great tips!
[EVO 4G General] NYG27:
Thanks for sharing, I had never hear of that method of conditioning a battery. I just loaded a new ROM (Destroyer v2) this morning and will test out that method tonight without any of the other steps. Then after testing the phone for a whole day, I'll add in the steps I've listed the following day to see if there is any improvement either way.

If there is battery improvement with conditioning the battery with that method, I'll add it to the Best Practices in my originial post and give you credit. Thanks again.
[EVO 4G General] NYG27:
I'd like to hear your feedback after you've tried those steps with either the CM7 or MIUI ROMs. Those are the only two ROMs I've tested, and just loaded Destroyer v2, to test that out also in the coming days. As for the widget, I've tried it and it is a good tool but also read that having too many widgets open drains the battery more (haven't tested though).

Thanks, from my point of view, if someone is going to take the time to complain about spelling mistakes and other details without giving me the time to add\correct them. Then they have more pressing things going on in their lives and if sounding off on a message board makes them feel better, more power to them. Life is too short to worry about stuff like that. :D

Also, do check back to my original post. I'm going to constantly update it with new battery management methods that I read about or find to test out. I also will be testing other ROMs, especially sense based ROMs to see which one of these steps could cross over and work with sense ROMs.
[EVO 4G General] NYG27:
I haven't tested the new version of Timats yet and just my personal preference, thought Savaged-Zen outperformed it. Although I haven't tested Timats 3.3.7 yet, which has been getting alot of great reviews. I'll compare that new kernel to SZ in the coming days.

MIUI is a great ROM and my favorite so far. Although I'm a ROM junkie, so I want to spend a few more months testing other ROMs before I go back and make MIUI my daily ROM.

Changing the levels on the VM Heap Tool and changing the voltage to 50mV, got rid of all my Force Closure errors I got on MIUI before. I tried changing the voltage back to 75mV but got more FC so I switched back to 50mV.

Great thing about MIUI and CM7 is that they both come right out of the box with only 4-5 services running in the background, which saves alot of the drain on the battery. Adding those other steps just adds to the already great battery life those ROMs offer.
[EVO 4G General] Justin.G11:
A noteworthy undertaking to try to help peopel with battery life. I will state, that in order to be complete, you should include a mention/nod on task killers and why they are bad, as well as maybe a little more info on what Juice Defender does so the reader can determine if it's a good fit because honestly Juice Defender is not great for everyone (For example, I only use it in a custom mode because the default policies have trade-offs I simply can't make)

If it would help, I have my own little blog and I happened to post on these two topics not too long ago:

Ego Too Big to Virtualize

It's not complete but it could be added to your original post as you see fit.
[EVO 4G General] NYG27:
Thanks alot, really enjoyed reading that blog about the task killers and controlling the polling of e-mail. I had read they are bad for your phone, which is why I didn't add them in my Best Practices. Plus in my Step 10, I wrote I turn off polling of my e-mail account but your solution is much better then just manually going to refresh e-mail.

I'll definitly add a condensed version to both those topics in my original post about battery best practices and I'll add you to the credits. Plus I'll add a link to your blog for anyone who wanted to read about them in more detail.
[EVO 4G General] zerowonderboy:
You said in the OP:

"On Average, battery would drain 8-12% per hour of constant continual use when playing games, watching videos or listening to music"

Thats god-like to me. The best I've ever had with any kernel/ROM is 25% per hour. Do you have any radios on while doing these things? Do you have a screenshot of display on time in battery usage? Also, how long should I leave the setup to see actual accurate battery life, a few days?

Sorry for all the questions :D
[EVO 4G General] NYG27:
I just totally updated and revamped my Best Practices. Go back to my OP and re-read the steps for the best results.

As for your question, I turn off GPS unless I need it. I use WiFi at home and work and 3G most everywhere else. (Sprint still hasn't setup 4G in my area in Maryland).

As for screenshots, they're useless, for all you know a person could turn on the phone, not do anything for 2-3 days and take a screenshot right before the battery died claiming they got 2-3 day from their battery. In my OP I detailed my phone's setup and what I used as a bench mark.

As for performance right away, once you upgrade the kernel and lower the voltage, you should see a big improvement right off the bat. For best performance, follow all the steps I listed.
[EVO 4G General] zerowonderboy:
So at 87 percent for me with your exact setup except for having miui 1.4.22, I had 31 minutes of screen on time. So you have about double the battery life as me. Do you by any chance use setcpu?If so what governor. Im using smartass 128-1152 min/max. I also can't figure out the email thing you were explaining in the OP. When you talk about accounts and import in mail, what app are you talking about gmail, normal email, accounts and sync in settings? I cant for the life of me figure out how to get my aol going through my gmail.

Thanks for all your help btw!
[EVO 4G General] NYG27:
I got my EVO about a month ago and just use the standard stock battery it came with. At first I was only getting 4-6 hours using the default Sprint Sense ROM it came with, so I've been looking non-stop to find better fixes.

I've only done steps 1-10 in my instructions. I don't use the setcpu app and get on average between 15-20 hours of battery life depending on mid to heavy use. With this current setup, I've never got below 10 hours battery life on really heavy use days.
[EVO 4G General] NYG27:
As an example, just this morning, I took my phone off the charger 3 hours ago. Downloaded one app from Amazon App Store, some mid use of the phone with surfing the internet about 15-20 minutes to read about news\sports. I only have 3G turned on and listened to Pandora on the way to work (45 minutes). Currently I'm at 87% battery life.
[EVO 4G General] zerowonderboy:
Thats amazing. Oh well I don't think I ever will be able to get that type of battery life. Maybe my stock battery is getting old. And have you ever tried Deck's gingerbread rom?
[EVO 4G General] samsonite.ace:
thanks man i appreciate it! good stuff most was already a no brainer about kernals, but thats bc im a flashaholic
[EVO 4G General] NYG27:
I haven't tried Deck's ginerbread rom yet but did flash 7 different roms the first 3-4 weeks I had the evo. Just my opinion, I liked MIUI the best and now that the GPS and Visual Voice mail issues have been resolved, I see no reason to switch and been using MIUI as my daily driver.

Only bug left is MIUI resolving the 4G issue but since I have no 4G where I live, I not no issue not having 4G for now. I might feel different once Sprint installs the 4G towers in my area the next 6-8 months.
[EVO 4G General] onlinespending:
I notice you still list a kernel from 4/7, despite having updated this post yesterday. Do you recommend any of the newer Savaged Zen kernels?
[EVO 4G General] zerowonderboy:
I agree. Deck's and MIUI are the only thing I use now. Just because of the stability and how smooth they are I love it. The only thing im searching for is battery life. Im dying for a screen on time for more than 4 hours.....

You can initiate connection from both PC and device (tap PC Synchronization in TouchXperience to etablish connection from device). You can connect via USB or Wi-Fi, but the first time you have to connect via USB so WP Device Manager can deploy TouchXperience and your device can get your PC IP address.

In the current version you can't manually set the PC or phone IP address to connect, or change default ports.

Make sure port 8007 is not blocked by firewall on PC and port 8107 is reachable on device.

When WP Device Manager initiate a connection, if it can't connect to the phone, in case you are connected via USB it will launch TouchXperience, in other cases it will send a push notification to your phone asking you to manually launch TouchXperience

Some tasks requires that your phone screen is unlocked

It is not necessary to have Zune runing in order to use WP Device Manager.

If you have connection problems, try the following may help: unplug/replug your phone, close or start Zune, restart WP Device Manager, make sure your device is detected by Zune.

In order to use WP Device Manager from Windows Device Stage, you must have Windows 7 and driver signature verification disabled, unfortunately this is because Windows 7 recognize only digitally signed drivers.
