[Q] Good kernel/rom combination for me?

Hello,
I'm currently running:
Slick2x-F V4.5 (android 2.2.2)
+
HTC Sense 3.0 theme
I'm not sure about my kernel, I haven't flashed it but one of the roms I used might have flashed it, not sure.
I'm looking for a good rom/kernel/theme combination which looks good, performs well and maybe the most important thing, gives a good battery life. A good battery life is about 15-20 hours with about 2-4 hours of heavy usage in those hours. I currently get around 14 hours using the phone heavily for around 3 hours a day.
The current combination I was looking at:
ROM: http://forum.xda-developers.com/showthread.php?t=1254359
Kernel: http://forum.xda-developers.com/showthread.php?t=1295486
Theme: http://forum.xda-developers.com/showthread.php?t=1178640
Will this get me good performance + battery life?

I can tell you one thing for sure: any GB based ROM will be less easy on your battery life, it seems like Froyo releases are better are that, ATM.
I am currently using Topogigi's ROM, with SP 1+2+3 applied, and have just flashed HP kernel SR1 so it is too early for me to say anything on battery life; beware, though, that the latest HP kernel has a very strong vibration even in haptic feedaback and this in my case messed with the 'tap side' gesture to move in between your text... I had to disable this feature or the cursor would keep randomly jumping to the left.
If you are looking for best battery life, stick with Froyo: using stock v10d I managed to use my phone for two entire days with light usage.

Thanks, I'll keep that in mind

for me, i use GR4 modaco(v20j) 2.3.4
Code:

and the kernel i use neoblaze
Code:

the combination is good, i get 6452 score on antutubenchmark(oc 1,4GHZ), and it's still using ext3
you can use horsepower kernel from spica check the development section. i think it's pretty fast support ext4 (haven't tried to flash it) and it's already stable release
Code:
http://forum.xda-developers.com/showthread.php?t=1295486
or you can use CM7.1 it's 2.3.7 and the function like bluetooth audio & fm radio already functioned
or miui or any other rom in the dev section. have fun flashing

I'd say that the most stable rom is topogogi 2.0 + all the 3 sp's.
Combined with the sr6 kernel from spica it is very battery efficient (About 1 day
and 14 hours with light usage).
If you want to get a lot of juice out of your phone then get a froyo ROM.

Just wait a few days untill v20l roms start popping up, they probably have increased stability + battery life

They don't... They only updated the ROM not the kernel so the kernel should drain the same amount as it did before (and from my experience that kernel drains a lot!).

I vote for MIUI 1.10.28+Owains tweak pack (with swiftextreme)

[Q] Blitz - Battery and Freezes

Hey Guys, I've posted in other conversations about bad battery life with blitzkrieg and it seems pretty split down the middle between those who experience good battery life and those who don't. I did follow the advice and wait several days after I re-flashed blitz and my battery has yet to level out. I keep background data off at night when I go to bed, I went to bed with 93% battery left and woke up 7 hours later with a 23% battery life - while the phone was at rest.
I also have a problem about once every two days my phone will freeze up and restart. When it happens it just gets froze on screen and the whole phone vibrates for 20-30 seconds and then restarts.
Has anyone experiences these problems and found a solution to them? Should I change my settings at all?
I really don't want to get an extended battery but with the life my phone is currently getting I don't see much more of an option.
Thanks guys,

The phone freeze/reboot is a known issue with no known resolution. Before I dropped my last phone it had that problem consistently from stock v4 through every variant of the ota updates, revolt roms, gingervolt roms, kennels, scripts, no scripts, blah blah etc.
Now, however, I picked up a second Revo and have run it through gb and flashed gv 1.3, blitz 2.1 and various scripts and tweaks virtually mirroring my old device. I did that Monday morning and haven't had a single instance yet! These guys here do awesome work..
As for the battery draining, I haven't put my extended battery back on this phone yet because I was curious how the stock would perform with these mods. For the first couple days I was discharging at an even 10% an hour. Yesterday and today its dropped to 7.5%. Why? No damn idea. But I can live with that.
So, nothing terribly helpful here but just a disclaimer that your mileage may vary and a nod to the devs here doing kickass work. Good enough that I actively went looking for another Revo instead of fussing with a second line upgrade. That speaks volumes.

Oh yeah I'm not dissing the devs at all they're great!
The revo is a strange device all the reboots due to GPS and airplane mode I'm sure is a hardware fault because every revo I've had has done it and I'm on my third. I love blitz and can't live without my overclock lol I'm just wondering if there's special settings or CPU governors I'm not using that would help.

I've used CPU Master and am on ROM toolbox now. Can't say I've seen a significant difference between the two as far as battery goes. I've used both ondemand and smoothass, same deal.
I did have some luck limiting reboots on my first by bumping up the min to 768 but haven't needed to bother on this phone so its 2 something. No extra settings or anything. : )

Guess it's just the screwy differences in hardware that make some a better build quality than others. Well I said I wouldn't do it, but I lied...
I'm restoring to my GV 1.3 pre-blitz image as I type this. Guess I like battery over performance, we'll see...I may be back to blitz.

Can somebody explain the difference between ondemand and smoothass. I still don't understand them that well. Thanks!

I didn't read the whole thread but seeing profiles for the kernel helps a lot like when my screen is off my phone is set to minimum on the min and max which sometimes causes lag turning on but once the screen comes on it's up and running fine. At that level if I keep the screen off it takes nearly an hour to drop a percent.

Perhaps this is not the best reference but here is one about charging your Lion battery:
This link won't paste:
[URL="http://dottech.org/tipsntricks/17705/tip-condition-your-new-cell-phones-battery-to-make-it-last-longer-but-be-sure-to-condition-it-properly/[/URL]
It points out two possible issue:
1) over discharge (perhaps our meters account for this,
2) getting the battery hot, my phone does warm up setting on the charger, sounds like the usb port charging might be better for the battery?

Best Battery Life - 3thparty battery?

Currently using the lastest CM7 kang + Etana kernel. While i am pleased with the performance i'm not pleased with the batterylife.
I've been updating Kang and using custum kernels but my batterylife seems to keep descreasing every time i change something. Probably because of the multiple roms version/kernel tweaks which do not always like eachother.
I'd like to start over but before i do i'd like to know which rom/kernel combo is considered to be the best for batterylife + smoothness! Any recommandations?
Second question - i've read several threads about 3thparty batteries but none seem to be conclusive - is there a battery which beats the stock battery?

Did you calibrate battery after flashing ROM?

I use Owain's CM9 with Harsh Kernel and the battery life is amazing!

I got the best battery performance if i am using 313 baseband with 725 10d RIL. I also use WIUI 2.3.30 as a Custom ROM with ETANA - Kernel with LOC - DS -OTF flag ;-)

it happened to me when i first install cm9, even use match ril&bb , the battery die quickly even i do nothing . but after i install harsh' kernel,battery be normal .
so,i suggests you use another kernel for cm7, from top topic in android development forum. hope this can help

I am finding my X2 only lasts about 4-6 hours. i take a couple of fotos/video, use wifi etc and its dead so quick. i read about reseting battery and filling the cells with the OFF charge on Charge method. so far i have charged full while on. restart charge while off. its on what looks like about 95% and has been on 1 extra hour still not full. is it a bug?
ok so next i disabled alot of stuff uninstalled car home etc and run on 2g etc,
is there anything else i need to know for battery life.
i read a tutorial on this site had a huge list of things. ive done those so far.
just cant get the battery to charge full while off charging.

ok did a few of the battery mods used "juice defender" uninstalled car home etc.
on standby with "wireless left on" and sync left on. 10 hours 40 minutes..
is that bad. I THINK THATS REALLY BAD. right?

battery saver

hi, currently i am on darky rom 10.4.2 xwjw1 rom... i have tried different modems on it.. i am happy with the rom but only problem is battery.. i am not happy with battery life.. will going to semaphore kernel will help battery life??? or give any other kernel or rom that gives me more battery life like upto 2 days... if performance degrades little than its ok with me.. is there any hack or scripts which will improve battery life??? battery juiced a lot when using 3G.. please help me guys... any good battery saving ICS rom will also do..

With Darkys i had the "best" battery with XXJVQ, Semaphore and turned off 3g. Just had a widget to toggle 3g quickly. That just saved 20% a day for me.
And i know thats not exactly that what you want but moving to ICS increased my battery life pretty much

thanks for replying.. but i use 3g internet and i do switched it off when not required.. and i am ready to move to ics rom... which ics rom are u using??? what combination gives best battery life??? also give links if possible...

Well, first of all, there applications that are supposted to increase battery life. For a few examples, you could try Juice Defender(my personal favourite) or Watchdog Task Manager. I personally did try some GB Darkys' rom, and I wouldn't recommend it. The battery life was terrible. I'm now running WeUI, an ICS rom. I also tried CM9, and it had a pretty good battery life, but it's not really what I would recommend you to use as a daily usage rom.
You might also want to check your screen brightness settings, I personally have mine set at "automatic".
Also I'm not that sure if semaphore has a good battery life. I heard that Icy Glitch has better, but I am still running semaphore 1.0.0.
Let me know if those apps make any difference!

Back in the day when i was a darky user, i also tried semaphore and hat good results with it, 2days or more were common. I used BUJV3 modem mostly. But generally I had 2g running. The battery life always drops a lot when you constantly turn 3g on. Btw moving to ics reduced my battery life, I charge every night (sometimes earlyer).

i have juice defender... also i turn off the 3g when not required... and i have set the brightness to minimum.. but still i want to conserve more battery... can any one give me the kernel which uses lowest battery without much performance lag??? any ROM??? any good ICS ROM with good battery???

you can undervolt..
http://damiangto.emc2production.org/viewtopic.php?f=11&t=314

I was using an app called SuperPower XDA-BETA v0.80, that can be found on market.
As for me it's the best app for customising power usage, a bit tricky, and rot needed for most features, but I was finally able to prolong my battery life to 2,5 days.

i don't think so apps can save much battery as it will switch of the radio services which i am already making off when not required.. i am talking about battery Hacks or Kernel or ROM which will give extra battery power???

]Dude you want to use 3G too and still want battery life of upto 2 days !!! quite a dream...
anyways few things you can try on.. these are not hacks just tips
- remove any widgets on your homescreen
- turn off autosync
- don't use any constantly updating apps like weather, clock widget etc
- turn off auto rotate (read in some thread this as a tip too)
- don't use automatic task managers
- don't use any battery saver, turn off the data manually when not using everytime
- don't use live wallpaper and try to use some dark background image preferably black
- use some black and white theme
- remove/ freeze as many system applications as possible which don't affect your normal functioning and the apps that you don't use

[Q] HTC One Battery Drain(mA)

Hey Guys!
I really like this forum and I saw you always get help here when u have problems.
So here I have a simple question and I hope a few people have a little time and ambitions to help me with it.
I always felt my battery drains quite fast since I installed Android Revolution HD, now I'm still on Android Revolution 9.3 and its not better since then. So I installed Battery Monitor Widget, because it seems it's the only widget which actually shows the battery drain of the HTC ONE(M79
in mA.
So my values are often between 200-600mA(mostly 299), even when I'm on Homescreen and it should be idle except the background processes.
It would be nice if someone could post me his values so I have something to compare.
I'm running on Android Revolution 9.3 with ROMCleaner NO-Sense.
Thx for help.

Those values are normal for screen on and idle Deep sleep after about 10 minutes of screen off should be around 10-15mAh

Okay this i can unterstand, but can u confirm that your phone drains about 1A(1000mA) while gaming and gets really warm oO

Warm up during gaming is normal for quadcore phones
Sent via my Google Nexus 7 | 32GB.WiFi

yeah the warming up, but the 1A drain ? and even in deep sleep my phone drains 350mA, if i can believe the log of battery monitor widget.

I had a battery drain faster issue after I installed two mods. One is the sound volume one and the other one is I think the one with the volume wake up. Afterwards, I found the battery drained super fast - 10% per hour even idle!
I redid the ROM(ARHD 12.0 at the time), then changed to another ROM but didn't fix it.
Eventually I have to reinstall the firmware! Don't know which part, I suspect the sound volume one modified the firmware somehow triggers something very bad.
Hope this helps.
