I can tell you i've done this and havn't noticed any difference in battery change. I use skyraider 2.5.2 and KK #3 kernel. Bump Charge and work gets me well through the day with moderate use.

I've done this a few times too and haven't it do anything.

ive noticed a change when i charged fully while the phone was on and the light turned green then just rebooted in recovery and wiping battery stats i do it every time i flash a new kernel i mean my opinion i have noticed better battery life doing this process

Please help. Poor battery life. (Please see inside)

instead of flooding all other threads I thought of creating one of my own.
I am running ARHD 8.1 with faux kernel 006. Previously I was on stock kernel with ARHD but due to poor battery life I flashed faux kernel. With gsam battery monitor I saw that my HOX kernel is consuming 40% of battery. After flashing the kernel it remained the same. What is the matter I don't know. Is this the reason of poor battery life? This is my screenshot:
I also
Installed system tuner. The CPU is always running at 1ghz and doesn't allow me to change it. What could be the problem. I am totally messed up.

I noticed that you seem to have flashed and done a lot of mods to your phone.
Try flashing it back to stock, leave it that way for a week and let it stabilize.
You're doing too much expecting magic instantly.

Thanks but how to flash it back to stock? And does HOX automatically turns on when fully charged? It happened to me everything I charged my device when it was on.
Should I revert back to stock or should I wait for a few days with ARHD+faux kernel?
Btw I have installed system tuner. Any settings you recommend to save up more juice? I am a total noon with all these.don't wanna duck up my device again. I am leaving with full charged. Let's see how it goes.
P.S. just checked the battery consumption and these are the stats:
Kernel-42%
System(HTC launcher)-9.2%
Internet-2.3%
Charge is draining by 1% every 30 secs. Wow.

I use watchdog to see what's using the cpu and causing battery drain. Maybe try that app?
I agree with the poster above- go back to stock and wait it out..
If all fails then you might even have a faulty battery which is covered under warranty, but because of unlocked bootloader its risky trying to claim it.

Dude. Flash to stock. Don't install any battery apps. Wait one week.
All of your problems will be gone.

Oh yeah. Don't install system tuner, setcpu, anything. Leave it stock.
A lot of people go over board with apps and just bog down a good device.

can u guide me or send me a link on how to flash to stock rom and kernel

1. Find the correct RUU for your devices. They are in a stickied thread in the development section.
2. Flash stock recovery.
3. Relock boot loader. (fastboot oem lock)
4. Run the RUU.
To find the right RUU, use fastboot oem readcid and post your cid here and I'll tell you if I know the RUU. I'm not sure where to get the stock recovery, but this is what I've read others say about returning to stock.
Sent from my HTC One X

i am on ARHD which is stock so do i need to flash stock recovery. where to get the RUU and stock recovery? even on the stock kernel with ARHD i was getting my kernel using 40%. so should i just change the rom? if so suggest me one rom
edit: i went out at 9:00a.m with 100% came home at 1:30 with only 14%. had two reboots and only1hr screen on. there cant be anything terrible than this. will charging it again and again work. also the cpu doesnt fall below 1200mhz. its between 1200 1400 and 1500. i just want good battery life whether its dual core or quadcore. charge was 20% just after 1sec it fell to 14%. app usage is 54% with 41% consumed by kernel

You might have something eating your battery. And yes, you do need to flash stock recovery in order to run an RUU.

I installed cm10 and battery life is so far good. Just on my first charge cycle and got 35% left with 2hr 18min screen on. Is it good?

You cant really tell with your first cycle, you seem to keep a rom for a couple of days complain then switch. You need to wait a week or so to let the battery settle so to speak.

That sounds great to me. I usually get to 15% with 1hr 48m screen time.

Exactly. He has made a bunch of posts over a short amount of time.
My battery life is very good on stock rooted. Run stock for a week and let it calibrate. 1 days results are meaningless.

Good or bad we don't know. Depends on usage type of data used, signal, screen brightness, auto sync and various other factors that can contribute to draining of the battery.
But that seems average anyway so not that bad.

Run arhd super wipe Install a clean rom like aosp and don't install any apps, seems like you have a rouge app do you restore apps from titanium? Use watchdog like mentioned it will alert you when any app is being naughty and running cpu when not necessary.

Battery Life Decreasing Rapidly

Hi To All
I need help. I have my HOX stocked 4.0.4 rooted, installed with ncx 2.1.7 v13 kernel. I realised that my battery drain is about 4-5% an hour or so. It was worsed with stock kernel. To add in, every 2 hours or so, there will be high current usage notification from currentwidget. Can someone guide me what is the best kernel for battery life, n do i need to have other settings like governor or anything else to maximise my battery?
By the way, i have only go keyboard, currentwidget, rom toolbox pro and applications that does not use startup. And i can't flash a custom rom due to my HOX cid is htc_044....
I seriously need a good kernel with good battery life or a compatible custom rom with htc_044.
Thanks alot to those who can help me.
Sent from my HTC One X using xda premium

Every ics custom rom is compatible

But when i looked at the roms, it's all under jelly bean. How do i know which rom is ics?
Sent from my HTC One X using xda premium

Go to development subforum, there's a thread which lists all the guides, mods, kernels and roms. All ics roms can be flashed on any cid.

Oh and go install betterbatterystats. Get it, use your phone normally, and check under process and partial wakelock if you have a rogue app causing wakelocks.

Ok thank you. I will look it up. I really need a better battery life rom or kernel.

The best i have found is ViperX rom with FAUX'S o11 kernel

Thanks Paul. Really needed a good recommendations from users out there. Been having bad days with my new HOX and the battery life like that....

Paul, to add on, does viperx includes the beatsaudio thing? And with faux kernel, how is your battery life?

Hey guys, I tried ViperX 2.7.1 with Faux 011 kernel, and found that no apps are intefering with my partial wakelock and process. But still, after a screen on, it's just a matter of 2-3mins that my battery will drop 2-3%. Anyone knows why is that so? And what can roughly cause the problem.

Have you got screen brightness turned down to what is acceptable mine is on 25%or around that. Also have you let battery do a full charge and discharge cycle. EG let battery discharge just below 14% My battery is alot better now then when i first had the phone, It does take a week or so to get better battery life after a few charging cycles. Also now you have flashed new give it a couple of days before you start to compare to let it settle so to speak.

When did u flash Viper ROM? U need to give the phone at least 3-4 charge cycles before complaining about battery life...Faux variant Free V11 for me is the best..have a look...but the most important thing is let the phone go through at least a couple charge cycles..and trust u will notice a huge improvement in the battery life.

NO. Don't discharge your phone. Li-ion batteries don't need discharge cycles. If you do that, it loses battery life.

I can not see anybody suggesting he lets it fully discharge.

If there's anything that i should do more, do tell me. Coz all the while i've been using my Incredible S which fell into the toilet bowl. So abit excited and worried.

I have tested this stock v custom and the custom was roughly 18% improvement to the stock rom and kernel. Got to admit when you first get them you can not put them down so the screen and other apps are being used more than you may think LOL :laugh:

Heeee thanks guys!!!

Nope. The best for me was ncx kernel with viperx Rom, it needs to settle down (2-3 days) and I have 3-5 screen on time depending on tasks I do.
To the op.
I cant say anything about your problem, since you havent said anything about your current batteey time.
You can try all kernels available here on the forum, because all of them are compaitable with ics.
There are 1001 of battery threads, so no need to open new one. Just go and read, me myself wrote about 5 big posts about battery Life and how you make it netter...no need to repeat it at all.

[Q] Friendly Custom ROM for battery

Hello, what is Custom Rom which is not drain battery too much or saver for battery?. I've some problem with some cusrom that drain battery too much.
Sent from my GT-I8150 using Tapatalk 2

Are you following the charge steps?
Like wait till 3-4 times charge cycle before complaining about the battery?
Because when you just flashed new rom you should do that. And cosrum didn't drains battery too much. Although yes it is drain a faster than GB rom. But not that bad.

If you're using CM9b4, try the CastagnaIT Kernel.

Battery drain on 4.2.2 Roms

Hey guys, I have a terrible problem here. The problem is that I got tired of Sense and I love stock android 4.2 and I just cannot use roms built on that android version because the battery drain is humongous. Using my phone just to check twitter and facebook and it goes down in 3 hours. I tried Cyannogen Mod and I'm now on Icecoldjelly both with Xm kernel and it is always the same. This is terribly annoying because the roms are perfect and so is the phone, except for that battery. Does anybody recommend I do something, are there some mods/tweaks to increase battery life? Is I cleared battery stats and performed more than 3 charge cycles, in case you ask. Thank you, hope you can help me
Sent from my HTC One X using xda premium

haha! and I thought I was the only one... I see people who are getting 15-18 hours on ICJ...
I also get terribly low battery backup... even though battery is calibrated.. Sync off... Auto Brightness.. etc etc...
However, on sense roms I get great battery!

I would suggest a faulty battery, I use mine for twit and fb too and a whole load of other stuff but i get a lot more than 3 hours. I am on slimbean 4.2 now but I have tried cyanogen 10.1 and icj, both of which gave me similar battery life to slim, although neither of them could equal slimbean they were not as bad as you are experiencing

The reply wasn't intended to get you to try slim, only to show that not all 4.2 roms are as heavy on battery. there are plenty of others to try, I just prefer slim

I get around this much:

I'd say thats about normal, but the op's 3 hours is seriously wrong. I would have to use navigation, music, facebook, twitter and XDA all at the same time to run my battery down that fast

With minimal usage I got around 5/6 hours. I'm going to try other roms and settings to see if I get this right. I'm currently on slim. I'll see how it performs tomorrow. If it goes bad then wth, I'll just go back to a Sense rom

Disable auto sync/fb location... use trickster mod and set governor to smartmax and IO scheduler to row/sio...
Cap the max frequency to 1.2 GHz... Use greenify to hibernate apps which you don;t need..
There is absolutely no lag for me... When I want to play some games I just switch to interactive or gaming governor!

Thanks everybody, I found my daily driver, today I got 13 hours with regular usage and still 25% to go, slimbean is the best. Even if it was not a recommendation to test the rom, it helped a lot
