[Q] Flashing unity kernel + battery life - HTC Incredible S

Hi all
I've unlocked the bootloader on mine through the htcdev site and am currently running Niks latest rom.
However after flashing Nik's latest rom, I'm finding that my battery life has been horrible (i very much doubt its the rom, lots of people have commented on great battery life with his). Can just scrape through a full day's use of texting, some web browsing and music playing. After some browsing on the phone, it goes down from 100% to 90% in about 10mins I've tried increasing my battery life by following the method found in this thread http://forum.xda-developers.com/showthread.php?t=701567 but it still hasn't worked for me.
After reading the forums, I've heard that unity's kernel supposedly brings better battery life and am considering flashing it. However I'm not sure if i can flash it given that I haven't rooted my phone or done an s-off?? Can someone please give me an answer on that?
Also, is there anything else I can do to increase my battery life?? It's so annoying having to impose restrictions on myself to increase battery life when my friend's S2 drops to 98% after some browsing and 3 hours of standby...
Thanks so much guys

sometimes, a custom roms make your baterai drain fast.
why? so many tweaks and overclock at cpu.
so, you have other options to change your custom rom.
example, ARHD 2.1.3 make your baterai not drain fast.

If you don't have full s-off, then you are restricted to whatever kernel comes with your ROM. I'd recommend you look into SetCPU if you haven't already, which will improve battery life by regulating how your processor is used. Juice defender is an app worth looking into as well. Have you tried flashing an earlier version of the ROM? Sometimes you can get a build where the kernel just doesn't work well. You might find your battery life improve with an older version, with a different version of the kernel. You have nothing to lose by trying I guess.

As man, not the answer I was hoping for. Thanks for the info, ill give that a try and see if battery life improves. If not might go the whole stretch and get an s-off

Terrible battery live on cyanogen

Since I rooted I've been getting horrid battery life. I used my phone for 10 minutes today texting and the battery life's consumed 7%. This is not good.
Check in your sync to make sure your calendar or contacts ect. aren't stuck trying to sync. This happened to me, and phone was dying in a matter of a few hours.
Mine is like that too I was thinking about switching to Another since I hear that Rom gets better battery life.
There are several existing battery threads. You should ask questions in there.
Hardly used my phone for 40 minutes today and down to half battery life. Can't somebody throw me a bone here?
You could try flashing one of the undervolted kernels from IntersectR or Diet. I noticed it helped a fair bit on the Cyanogen rom. Another option could be to switch to the Enom 1.8.1 rom. I'm currently running the Enom rom with IntersectR hybrid kernel and get fairly good battery life.
I had this too, flash any other kernel and it seems to fix itself. Intersects is a good call.

Same here, man
I flashed this kernel:
OC/UV kernel + HTC_Camera Addon for 1.8.1
and this rom:
TheOfficial_Nexus1_v1.8.1_update.zip
from this thread:

Is that the kernel that's being praised for having good battery life?

I'm running this combo, and I get 10x better battery life than on Cyanogen's!
Good to hear. Ill report back with my findings after a few days useage!
I was having battery troubles, but I just charged my phone fully then wiped the battery stats in recovery and have had great improvement.
Is there such thing as a desire ROM that has good battery life for the N1?
sorry, Cyano506 has great battery live... you must be doing something wrong..
yeah I must of installed a cyanogen from a different person...
....hey--wait a minute...
Battery CM 506
..this is not too bad for 506...
Thats what I am using now with the addition of juice defender free which gave me a small but noticeable boost in battery life. These things together gave me the juice to make it through the day without scrimping on my usage, before I had to either scrimp or charge during the day to make it.

well damn. I am currently looking for a new kernel. What are u running? I have a kernel from late January. From what I hear there are several good ones out there with better battery life. I am running 5.0.6 also
I don't understand. Look:
I've hardly even used it :S

[Q] Fastest Rom & Best Battery Life

Does anyone have any recommendations for a rom that is pretty fast and smooth while having great battery life. Also any tips to get really good battery life such as processor speed and kernels etc..any opinions appreciated.
I use jaybobs aosp or cm7 with .29 kernel so I can use my headset. I use setcpu and clock 576/691 at full power then drop it if battery gets too low or raise it when I'm charging. The only way you'd extend battery life drastic is to live with a good signal and actively manage your data connections and sync.

hmm i will try it ive used cm7 and aosp but they seem to lag for me when im using the keyboard alot but ill try that kernel and see how that goes. I guess what you said about the battery life make sense cause i live in a area with pretty bad sprint service. guess i can fix that by turning off data while i plan to not use my phone thanks for your respond. Anybody else have any suggestions?
I recently just installed jaybobs rom (august 14th) like 4 days ago. I use the kernel .35 CPU=480min/710max
along with the v8 tweaks, and firerats.
As of right now my battery is 19h 29m 0s on battery at 21% battery level
Texted a lot, talked for a few minutes, update apps on market. I only use it to talk and chat cause i have a tablet that i do my surfing or gaming stuff =P

Could you send me a link to this v8 tweak? Ive never heard of it but im willing to try anything i usually get about 12 hours battery life.
I don't think the v8 helps the battery, i think it's just for performance. u should try it without it first.
heres the link to the v6 tweaks

Well im running OMFGB August 12 nightly its one of the fastest and smoothest 2.3 rom ive ever used i havent used the aosp verion though so i dont know how smooth that one is. And i have email syncing and facebook and i use google voice a lot i mostly do texting and i keep my homescreens without any widgets that need to update a lot. i also calibrated my battery so i could get pretty decent battery life which in my opinion is 12 Hours but im still looking on ways to improve it.
ohh, i see. Yeah i know where ya comin from, I've done a lot of flashing and just decided to go with the most stable. They were all somewhat smooth but as for battery life, I've gotten the best battery with jaybobs rom.

For Battery life I would recommend extended 1900mAh batteries.
I didn't have to buy custom cover since they fit in the stock back cover.
2 batteries with external charger with shipping would cost you about $20.
I get about 2 days on a single charge with moderate use.
I am using CM7.1 nightly 160 at the moment.
If you are interested let me know I will point you towards the retailer
I bought them from on Amazon/Ebay.
Well im going to try jaybobs rom then and see how that does yesterday with OMFGB rom i got 11h 59m 2s and after that it shortly died off and im just running setcpu at 729 max 691 min performance lol i think i really need to change that if i want save battery does any one have any good setcpu profiles they would recommend? And i might look towards buying a extended battery but i dont really want to seeing as my upgrade is in december.

Well that is what killing your batteries right there
I am no expert but I will tell you what I use,
I only use 1 profile besides the main one on setCpu:
Screen On/Main: 691 max 176 min (On Demand)
Screen Off: Max 264 min 19 On Demand ( Since I dont use it for music or anything else screen off with min 19 is no issue for me)
By the I also use v6 Super Charger and V8 kernel tweaks and they do make
your phone very snappy and responsive!!
Best of luck
I recently flashed gingerbread hero deck and it's pretty nice. But, something weird I notice is that my 3g download speeds have dropped off considerably (from 1200kbps range to 600). I can't explain it. I was on aosp's 5-23 rom before. I also recently started using firerats mod. Not sure what's up.
Sent from my HERO200 using XDA App
Its the build prop that causes it. I'd use the V8 3g tweaks to see if it helps.
okay ive installed OMFGB 1.3.1 nightly 8/17 and with the V6 scirpt runs well along with the v8 and the 3g one which i cant recall the name of but everything now runs really good but im still calibrating the battery so i still have to see how that goes but so far its been good. Thanks for the tips everyone now to try out this jaybobs kernel hopefully everything will still work well.

[Q] Cyanogenmod 7.1 Battery Life?

Hello all,
I have seen reports that because the source code for the captivate has not been fully released, some of the processes cannot be put to sleep when they are not being used, and therefore causes bad battery life. I am just about to flash CM 7.1 and am curious to know how the battery life is on the captivate.
All info is greatly appreciated!
LWt mw know what you find out! Just flashed it and my battery goes quicker than my bank account. Please let me know what I can do to help this I like the rom

Jaye,
This happens frequently when flashing a new ROM, you should try wiping the battery stats or giving the ROM a few days to calibrate with the battery.

You should try a custom kernel like glitch or Neo to see if that will help. I get awesome battery life in miui which is bases of cm7. I find that neo gives me the best battery life.

Yeah that's pretty awful. Try doing a battery calibration to see if that helps. It should never go that quick (unless you're playing some serious games). I've never really had great battery life with cm7/miui I've had the best battery life with all the recent samsung gingerbread leaks. I think those are better than cm7. But that's my opinion.
I am in CM7.1 since Sunday. I had very awful battery in start. So I did battery calibration, manually. So I got very decent battery on wifi. But at work I use att data so again my battery life was horrible. But I am seeing improvement since I am using this app called green power to manage my data. Try that.

If you get good battery on WiFi but not with mobile data, try a different modem. Not only are some modems inherently better on battery, but if you find one that gives you a better signal you should see improvements in battery life as well.
Flashing the Glitch kernel seems to have improved my battery life.

Hi, Can you point me to a post that (a) has the Neo Kernel and (b) explains how to flash it on MIUI? I've had MIUI for a couple of months now and battery is to as good as expected. Would love to try to use another Kernel but I sincerely don't know how to do it.

Solid Battery Life w/ Stock Kernel
Hey Everyone,
Juts came to report that I have been getting great battery life using the stock kernel. I would say it is a little better than Serendipty VII Build 2 which I came from. Only issue, and this is something I know is inherently wrong with Cyanogenmod on the Captivate, when you fully charge the device, it only shows it is charged to 98%.
Other than that, all good!

Have you seen an improvement in this regards, I am having the same issues, the WiFi is draining my battery slower then my data is.
I have also done the battery calibration and it doesn't seem AS bad... still doesn't appear to be great though.
I am just coming back to this ROM after experiencing battery issues even though Glitch helped a little. I decided to try and tweak some more this go round.
I am experiencing much better results this time. Here are settings and other tweaks or modifications I have in place.
-sync is turned off
-using Launcher Pro with very few widgets (just 3GWatchdog and Power Control)
-auto brightness turn off manually adjust according to need
-gps, wifi, BT, and data turned off when not in use
-wifi notification and location detect off
-installed jk4 modem (may get better results with different modem depending on your area)
-installed Glitch v12 high leakage
-the biggest factor this time I think is UVing on the Freqs that are used while phone sleeps >>>>>100/200mhz (set for the lowest UV setting possible on these that do not result in a sleep death or reboot when phone is put to sleep)

Root v ROM - Battery Life

I rooted my Vivid (AT&T) a long while back, flashed a custom kernel (Faux 007) and tweaked it a fair bit for a cleaner look and better battery life. It helped. Some.
I have work apps installed that are a pain to get authorized and reinstalled, so I'd rather not go through the trouble again if I don't have to. However, I would like to get better battery life out of my phone if I could.
So, anyone have any experience on battery life of root vs ROM? Any particular ROMs/kernels for fantastic battery life? I'm not using sense widgets so doesn't matter if it's sense or stock UI.
TIA

Personally, the Holics ROM 1.3 with Holics 0730 kernel has worked great for me.
SetCPU to control CPU frequency: Max 1.5GHZ, min 350MHZ.
I used the Intellidemand governor, and noop scheduler.
I do NOT use task killers.
I use Lux Auto Brightness to control my screen brightness (highly recommend it!).
I use the APN Switch widget to turn my APN off when not in use (basically always unless I'm sending/receiving an MMS)
I close my apps when I'm done with them.
There is also an app called Llama that you can use to control all kinds of things, like turning wifi on and off based on the time of day and/or your location, etc. It's pretty cool, but I don't use it presently. Here are two examples of my battery life, with moderate usage.

with rom and battery life it is easier to try the different ones for yourself to see which gives you better life, each device and person will have different experiences. I had good experiences with all of them but what worked good for me may not for you.

Agreed. I think more than anything it comes down to two things: your screen-on time, and your cell-searching time. If you are in a low-signal area a lot (like the woods or a basement, or worse - a basement in the woods (!!!)) you can expect to get poor battery life on just about anything. Also, if you're playing angry birds every waking moment, you're going to bleed your batter dry. Simple as that.
If you live in a good signal area, and have screen brightness as low as possible, you're already in a good spot. Any tweaks you can do might help, but probably not by 12+ hours.

You know, that's probably my number one issue, I just hadn't thought about it that way. On weekends, I easily last the whole day and have 40% or more left. At work, it's dying fast and often unless I plug it in while I'm at my desk. I'm away from windows and 11 floors up, so the signal is pretty poor.
In normal situations, the battery life does seem improved with the kernel I am using and the rooted/cleaned up bloat. But since I spend most of my time sitting in this chair with almost no signal, I notice that the most.
And as for trying out other ROMS, well we'll see when my contract is up and I pick up another phone so I can tinker to my hearts content while keeping a pristine phone for work. I just don't have the leeway to bork my phone right now.

When you were using faux's kernel did u remember to rename "mpdecision" and "thermald" to "mpdecison_dis" and "thermald_dis"? Cause that would also be why you didnt really see a bigger difference in performance with his kernel.

Best Battery?

Hey guys, just thought I'd poll and ask some questions?
So if looking for the best possible battery life (over peformance) which is recommended,
true official stock samsung ROM? or stock ROM e.g. Adrenaline ROM etc
I've tried Stocklite, Adrenaline and am currently using Thunderbolt. However my battery life never goes over a day, even with Juice Defender Ultimate and SetCPU profiles.
Any one else have any experiences with good roms? Battery calbiration tips? charging tips anything?
Thanks

1.The battery life depends more upon your baseband rather than the roms.
Ofcourse the roms do make a difference!
Eg. Earlier i was using Stocklite v7.1 on DDKQ8, and it used to last a day, now on XWKTM it lasts more than that.
2.The battery calliberation is said to be a myth as an official google android developer stated that it does not affect the battery in anyway. (Tried it personally too, no change in battery life!)
3.Underclock when you are not using heavy apps on your phone.
4.The way you use your phone makes a great difference, switch off the bluetooth,gps,data,wifi when not needed! Reduce the brightness, it saves the battery!
Hope all this would help you!
