[EVO 4G Q&A, Help & Troubleshooting] CCallahan:
Configuring this thing for good battery life is exhausting. Before root I had done most things listed in this thread : http://www.xda-developers.com/android/tweaks-for-superb-battery-life-in-evo/ and finally achieved pretty good battery life.

After root, I have never been able to achieve this even though the bloatware isnt running, have various tweaks on there for performance, and so on.

Have tried Fresh Rom with stock and Kings #11 and liked it but had terrible battery life. Tried Myn's 2.2 with stock, Kings #11, and Netarchy and battery was not much better. Now running AVA9 (no flashed kernel) and battery is no better. Have tried running setCPU on all these setups and does not help.

Any suggestions? Seems someone will say this rom/kernel combo works for them and another person will say it sucks, don't use it.

I couldn't stick with Myn's because there were too many bugs/errors. If my best bet is to go back to all HTC stock rom w/root then so be it.

.....and yes, I have read through the numerous amount of threads on this topic but no clear combination has been highlighted that I have seen. I use my phone for business primarily so it needs to last me as long as possible. The thought of increasing my phone size with an extended battery is not appealing to me.
[EVO 4G Q&A, Help & Troubleshooting] greyopaque:
I have stock rooted 3.29. I initially did the plug-unplug trick when I got the phone. Then, I turned off always on data, and set email, google accounts, and Sense weather widget to update once an hour. Phone behaves the same as when data is always on, so I don't even notice 3G off when the screen is off.

I get 8 - 10 hours under very heavy use (constant fiddling, email, games, internet, calls, etc),

10 - 15 hours moderate (surfing, ebooks, email, internet),

and easily 18+ with light use (email, occasional light surfing, occasional call)
[EVO 4G Q&A, Help & Troubleshooting] CCallahan:
I have everything the same as before root so with the bloatware and some other things not running would think it would last longer than stock......not!

@greyopaque...what was the reasoning for using stock rom instead of custom? Battery life or just never tried any of the others? Would like to know if your battery life is better with just the stock over others.
[EVO 4G Q&A, Help & Troubleshooting] 1Brite1:
Ditto....I am a heavy user and leave everything running that I need. I use the phone for what it was made for. After trying/not trying all different types of roms/battery tweaks/advanced task killers/battery monitors etc., I decided to buy another original red 1500 battery as I don't like the extended battery look either. So, until they come with better battery technology....I guess that would be the career to go into and make some money ;0).....we are stuck with the best phone ever...yet....with a battery life that sucks for those of us that put the phone to the test....have a great day!
[EVO 4G Q&A, Help & Troubleshooting] CCallahan:
Yep...only problem is having to shut the phone off, change battery, then power back on. All the while, missing whatever phone calls come in.

***My point of the thread really isn't the terrible stock battery but the fact that the pre-rooted setup lasted so much longer than the rooted w/custom rom. Why??

I would think the battery life would get better without all the bloatware and other worthless services running all the time.
[EVO 4G Q&A, Help & Troubleshooting] eyeballer:
Once again.. you need to check your apps. Most likely there's something causing a drain.. Try updating to the newest rooted stock roms (3.30). The new kernel is definitely an improvement.

As an aside.. what bugs did you have with myn's 2.2 rls2? I ran it, and it was fine. Now on rls3 beta and amazing rom with great battery (3.30 base).
[EVO 4G Q&A, Help & Troubleshooting] greyopaque:
To be honest, I've never tried anything else. I really like the stock Sense experience... and since this is a work phone, I need it to work without glitches.
[EVO 4G Q&A, Help & Troubleshooting] CCallahan:
Well....hopefully I can hear from some peeps that have used a good amount of custom roms/kernels, as well as the stock one and see what they think.

Cmon guys....let me know!

@eyeballer1......Myn's was just acting weird and I kept getting a "com.htc.bgp" force close that I couldn't fix. Also, I have tried the newest stock rom but it is just so darn plain jane didn't keep it on long enough to test it. As for apps, I have basically the same apps on my phone that I had before root (except for specific root apps such as rom manager, titanium, etc).
[EVO 4G Q&A, Help & Troubleshooting] fastfed:
Sadly they won't.. That is battery technology.. This world is pretty much stuck where its at and will probably stay there.. Its the one thing that is not progressing that much.. Even from the 50's

That said.. the thicker battery is the way to go.. Only you will know its thicker, and trust me.. ITS NOT THAT BAD! Believe it or not you get used to it.. If its for business, well then a thicker battery should not bother you at all, use it during the day and maybe at night switch back to the smaller one.. You know, for the dates and **** :)

The thicker battery will be a life savior.. All these battery tricks and tips help, but nothing is going to be mind blowing.. The fact is, this phone is extremely advanced and requires a lot of power.. I just except the fact that I need to be close to a power charger at most times..
[EVO 4G Q&A, Help & Troubleshooting] CCallahan:
I might go ahead and try Myn's new beta with 3.30 and see what happens. Looks as though I need to look deep into what is actually using my battery. I have always used K-9 for email and have heard it sucks up battery, but it only uses about 2% on mine and is the best email app I have ever found.

@fastfed......I'll have to ask my wife if I can go on a date sometime. ;)
[EVO 4G Q&A, Help & Troubleshooting] fachadick:
what helped me the most was wiping battery stats correctly (as per cyanogen wiki, but applies to all roms).

Charge to full, turn off, wipe battery stats. Turn back on, wait till everythings loaded, unplug. Use as normal until battery dies (do not charge at all until battery dies). Recharge fully in one go (meaning do not unplug while charging until full). Use and charge as normal.

This should be done whenever flashing new rom.

I also use k9 for mail. As I use Hotmail not Gmail.. is it really that bad? Anything else out there ?
[EVO 4G Q&A, Help & Troubleshooting] potna:
The biggest positive jump I have seen in regards to battery life was going from Cm6 to 3.29 ruu stock, then I ur3 to root.

I'm still sceptical that the 3.30 zip update gave any improvement to battery life as I have seen others report. In fact, I almost wonder if I somehow have less battery life now, but it could be in my head. It's almost impossible to approach this issue scientifically since I use this evo all day.
[EVO 4G Q&A, Help & Troubleshooting] hough77:
Try bakedsnack 1.8, its the best battery life I've seen on a rom w/o having to make all these stupid tweeks and disabling features on ur phone.
[EVO 4G Q&A, Help & Troubleshooting] crimeslunk:
I'm gettin great battery life using vaelpak 2.3 with the stock htc kernel. I imagine most of the custom kernels around are based off of older kernels and while they may have higher "performance" ratings though I have hardly been able to tell a difference between kings 11 or baked speed and battery, I think the newer stock kernel is your best choice no set cpu to worry about, its just simple. I'm personally gettin about 14 hours with almost constant music playing to bluetooth headset, a bunch of browsing, and occasional use of google navigation which is a big battery eater. With just phone and text use after 21 hours I was at 52% yesterday.
[EVO 4G Q&A, Help & Troubleshooting] omegasun18:
ok so i have literally flashed every major rom / kernel and a comination of each. I have found that with minor tweaking most sense based roms get close to the same battery life. some people will argue that this or that rom is best but I would challenge others to truely preform a test on them and i bet they would be suprised.

k-9 is only a battery hog if you have it constantly polling for new emails if you have it set up to scan constantly then it will take a reasonable about of battery life but nothing more then most other email apps with the same settings.

have you tried as was lsited above and recalibrating your battery? I am assuming you are a pretty heavy user from the sound of things. How long where you getting pre root and how long are you now getting rooted? do you have titanium back up set up on a schedule? If so that can cause major battery drain as it sometimes keeps your phone awake.

All in all with the information you provided no one can actually tell you what is wrong. there are to many variabes and everything we say is a shot in the dark hoping to hit common problems.

my best recomendation configure your battery stats as listed above, if you havent tried use the HTC trick (chrage battery for 8 hours turn off phone charge for 1 hour turn on phone unplug it or 2 minutes then turn it off and charge for another hour.)

Anytime you wipe data you wipe your batary stats and it can drasitally impact your phones "battery life".
[EVO 4G Q&A, Help & Troubleshooting] CCallahan:
At this point I'm not so sure my battery or charging device on the phone isn't defective. But, only time will tell.

Currently I am running the newest, non-beta Myn TwoPointTwo and Netarchy 4.2 non-havs. I also ran this procedure (which fachadick already suggested):

1. Phone on...charge until green light comes on. Immediately unplug and turn phone off.

2. Plug phone back in until green light comes on again. Immediately boot into Recovery and wipe battery stats.

3. Use the phone on battery until dies.

4. recharge phone to 100%

I'm still on step 3. Will report back after a few days.

I had never heard of doing this when switching roms so hopefully it will help since I have swapped out a good amount lately.

Does anyone know where to get the newest HTC flashable kernel based on the new 3.30 release? All I have found is the rom package.

I've been using this app on the G1 and the Cliq and it works on the G2. Seems to need tweaking but it definately increased the volume for me. I recall someone complaining about the low volume on the G2 so I thought to let peoples know it works...its in the market...v.3.6 by Meltus

I used to use it on my G1 too. I just installed it on my G2. However, I can not detect any changes, with any setting. Neither the in call volume or speaker sound any louder or better. The changes on the G1 were not just noticeable, but drastic, so I don't think I'm missing it.

Hi guys,

I just made the jump from my iPhone 4 to a Captivate because I wanted to have some more control over my phone. From the research I've done here, I am going to use the one click root and isntall the Cognition ROM and I have a couple questions:

1) Does the 2.2 Cognition ROM mean it is based on FROYO? If so, how stable is it?

2) Does this ROM include the tools to overclock to 1.2ghz?

3) If anyone can offer some insight into some of the musthave apps, I'd really appreciate it.

Thanks for your help!
[Captivate General] rickgrob:
Yes, the 2.2 Cognition ROMs are based on Froyo leaked builds. You will want to check out Designgear's thread here:http://xdaforums.com/showthread.php?t=786532

The current release 9.1.3 seems to be quite stable for most. Instability largely comes from problems in flashing, which can be avoided by paying close attention to the FAQ: http://cognition.theidiotshideout.net/mw/index.php?title=Main_Page

No, it doesn't. While I don't know your specific needs, it is unlikely you need an overclock for anything more than bragging rights. With 9.1.3 (which includes the Voodoo EXT4 lagfix) performance is pretty darn good. There is an overclock thread here:http://xdaforums.com/showthread.php?t=821397 that has some interesting info, but is not in Cog (yet).

Hope this helps.

R
[Captivate General] stuff:
1) It's quite stable. It's rated a BETA, but it's unofficial software. Basically a beta that was leeched from Samsung's servers.

2) No, it does not include tools to OC. Personally, I don't see a need to overclock. Maybe undervolt, but not overclock

3) I think sgs tools is a pretty good app to have. but other than that, it all depends on what you use. i use banking a lot, so I use wellsfargo/discovery apps frequently.

just get used to the android market and you will find some things you like.
[Captivate General] singlebeam:
My input -

The latest version of Cognition has been the most stable on my captivate so far out of all the different roms I've tried.

If you wait a few hours, DesignGears is going to release a new version of cognition based off of the latest FROYO leak.
[Captivate General] cappysw10:
This, Cognition is the bomb diggity!

Hi guys, got the i-9000 from Carphone Warehouse here in the UK about a month ago. Tried to flash JM8 on it without disabling OCLF so needless to say that bricked it (3BC was not enabled).

Sent it in for repairs, got it back a week ago and it's been one problem after another..First I experienced the "ghost downloads" from the Market and I got around those by constantly cleaning cache and data for Download Manager.

Then I noticed that I could not use the mobile internet almost 90% of the time. I mean I tried standing still, from a moving car, from tens of different areas and I basically can't access anything on the 3G network except for an occasional "burst" that makes it work for a few seconds. It just flips back and forth between 3G and H, looks like it's sending and receiving data for a couple of seconds then it just hangs and after a few seconds I get a "cannot display/connect" error in the browser or whatever other program I'm using that needs internet access.

So I thought Samsung must've borked the flashing. I went ahead and fixed my 3BC issue, reset it to factory default, formatted cache and flashed it with PDA JM8, MODEM JM4, CSC OXAJM1 hoping that would fix it. Well, it did fix the Market issues, downloads are now working properly and consistently. However, mobile internet is still borked..the only reliable way to use it is if it switches to G (GPRS)..I mean it's slow as hell but at least it's working..

Is there any setting I can tweak/change in order to make it work a little better or is the Orange 3G network totally crap out here?

P.S. I live around Bradford, UK. I'm on a dolphin 30 plan with included 500MB internet access.

Basically same phone from same company on the same network. Upgraded to Froyo using Kie hack early October and phone running fine without a lag fix and reception /3g working good (in London). If you haven't already done it, get my orange app from market and when you open it you will see option to use T Mobile network. With Orange and TMobile joining you can jump between networks whichever is stronger where you are. You will also need to ensure your network is set to auto and roaming is on.

See if that helps.
