I tried CM7 (RC13) and MIUI 1.8(based on 2.3.5) and both have poor battery life on my xt720(one day vs. two days with the stock rom or the 2.2 custom roms). Disable the wireless policy make just a little difference but not enough for me. i try to find anything else to disable without success. Any patch for that?
Hi
What are you overclocked at.
Sent from my XT720 using XDA Premium App
The default speed of this rom. I think the oc is 800. I use cpu tuner to manage under and over clock VS the battery %..
On 2.2 on milestone overclock i set the clock to 1000mhz vsel59....

i tried the daddy's gingerbread miui rom.. its awesome and fast... but killed my battery no wifi and email enabled- drained my battery overnight with starting charge at 70%. i tried sohrab's workaround.. but in vain.. went back to mioze's 6.3 rom.. stupendous battery life..

So I have Myns latest Rom and I was wondering about adding Setcpu to the Rom. My question is this. For those of you that have this rom, how is your battery life? Do you use Setcpu? Is it compatible with this rom? Should I leave it as is? I dont want to overclock, I just want to underclock when display is off to save battery. Any expert advice?
What kernel would you guys recommend? Again I dont want to make my phone faster, I just want decent battery life, and I know there are a couple of tweaks I can do. ( and yes I already know about the brightness, wifi etc)
Getting bad battery life too huh? I'm new to this rom and I'm trying out a couple combos. I have setcpu to underclock using smartass. I changed my kernal to one with more havs. I'll report my findings.

No I really havent gotten through a whole day with this Rom, so I cant say I have had bad battery life. I just wanted to know what you guys are doing and using out there.

I haven't gone a whole day either. But I will today. I will let you know how my battery does.

Im using Netarchys 4.3.1 toastmod CFS HAVS nosbc and I can average 15hours with standard use, 24+ hours if i ignore my phone all together.
I use SetCPU and Juice Defender (it turns off data when my screen is off) and i easily get a day of battery life, my minimum is 12 hours and that is if I am constantly using it
I have been using Myn's 2.2 with the netarchy 4.3.1-cfs-havs-nosbc kernal for a few weeks. I have Setcpu profiles to overclock ondemand at 1152 until my battery gets to 30% then runs at 998 after. Also have it underclock at 245 when the screen is off. I can easily get a full day with several texts, a few hours of surfing, a few phone calls and maybe an hour of games (Angry Birds, Let's Golf). Usually plug it in at the end of the day with at least 20% battery left.
I'm now finding that my biggest priority is battery life. My phone absolutely hammers through the battery at an alarming rate these days. I've heard that 2.3.4 roms are harder on the battery and I think it's since these came out that the problem has got worse.
I've tried nearly every rom in the dev section but I never seem to reach any conclusion about which is easiest on the battery. Any of you have an opinion on this.
Stock Rom with a UV Kernel CFS

The kernel is very important. Choose a uv kernel as a trinty one.
NsCollab is a very good Rom for battery saving.

Hey guys, I recently flash cm rc1 and been running whatever kernel that came with it. My battery life has been worse compared to stock froyo 2.2. I'm a medium usage person so I was wondering what kernel is best for battery life and what setting are people running for setcpu to maximize they battery life. Thanks in advnace.
Great question. I would like to know this too.

It seems no matter what the kernel and no matter what the Tom, everyone has different outcomes on battery life... try some out and see what works for you..

Yes, it is amazing the difference in opinion on this subject. I easily get 16 hours of battery life with moderate to heavy usage, and 1.5 days with light usage. And I am using plain CM7 RC1, without any CPU/Battery apps. Trinity or Faux kernels reduce this considerably regardless of the OC/UV combos I have tried.
To make sure you are getting accurate results and to get best battery life make sure you calibrate the battery (there is an app for this, or can be done manually). This has proven to solve problems I've had where I only get about 8 hours battery life after changing Roms.
Faux's is the only custom kernel I've tried, and my battery life is unbelievable. It's almost doubled.
ok so i got my charge 2 days ago and am rooted with Gingerbread leak,
so i have some questions.
First: is there roms for gingerbread? because i couldn't find any.
Second: what kernels are there for GB? can i use PBJ?
Third: now ever since i got the phone it drains batter pretty quick with everything off. and hardly using it maybe about 20% per hour. i tried undervolting with Setcpu but wasn't successful, so what app do you guys recommend to undervolt the charge? or any guides to do so?
thanks,
Check out the development section. Gummy Charged GBE is great

I did, thanks for the reply. now i have voodoo and on the recovery sais enable 100mhv something like that. is that so i would get more battery?
You can't undervolt on gb because its a leak meaning no kernel source.
I think setcpu will let you underclock which would give better battery life but reduce performance considerably.

Whenever you change roms, you should calibrate your battery. It works wonders

How much battery life are you guys getting? And whats the normal drain range Cuz am tryna figure out if i have a faulty battery

You need to return to stock, then fresh Odin GummyCharged GBE 1.9RC2.3 if you want Gingerbread as it's really the only modified Gingerbread rom. Eclipse is available, but i'm not sure if the dev still supports it or not. The quick battery drain is something that goes along with the fact Gingerbread is a leak. GummyCharged team has done a wonderful job with minimizing this drain. I have found it actually has better battery life than Froyo. That's just my personal experience.
Which one would have the best battery life? Or if it's a multi-step process (pick a certain rom then change kernals or something) could you link me/tell me also ?
I'm using Octane v2, and it worked good for the first day, but now it's draining my battery so quickly, even after the battery calibration. I'll lose 2% battery while watching a video for a minute or two.
airfluip1's KJ6 AOSP Style
I haven't done much testing but for the last few days I've been using airfluip1's KJ6 AOSP Style and the phone's battery just died after being off the charger since late Sunday. That's almost two days of juice on one charge.
I also have had excellent battery life with the MIUI ROM variants around the forum, but they are still works in progress and aren't feature-complete yet.

I don't think battery life will differ much between the roms we currently have available, as they all have a stock kernel.
Though under-clocking and juice defender work well for me, I am a heavy user, I've not been able to get more then 14 hours of use.

to undervolt, pay for tegrak ultimate from the market. then input dsexton's undervolt values from icbinb threads.
I found a way to not pay and u/v but thank you !
