Did I FRY my CPU??

First of all im not putting down anyone and there custom roms. As I am an avid flasher of them and there great features..
However.. Ive noticed with every rom I flash, my battery life SUCKS. I know kernels are suppose to have battery saver mods, but never seem to work for my phone. The only way I seem to get great battery life is if I odin back to stock. Its seems to last forever on stock.
On stock.. I would average around 10% drain every two hours of moderate use.. mainly texting..
On Custom roms I average 10 to 15 % drain every hour with same moderate use..
My question is, Could Overclocking have caused this problem??

Quite possibly... And unfortunately, you have to test different Kernels with your ROM to see what works best, or just ask the Dev which Kernel they used when developing the ROM... That's a good way to get the best battery life because after all, that's the Kernel the Dev based the ROM off of. Another option is to check out Marcusants post on setting up your Kernel for your ROM, and I apologize if you've already tried that... I'm just trying to list options... I've had problems with different kernels on different ROMS... Well at least until Rodderik started making his Kernels with Viper ROMS... Then it started working perfect lol. How are you running your clocking? Conservative? Performance? Also, are you using SetCPU with an OC/UV kernel and the Voltage Control app? If you use the two together, it could cause a lot of issues, you'd have to choose one or the other.
On the other hand, I could be 100% wrong and it could be just your flux capacitor... You know how touchy those things are. Try chucking your phone over 88 MPH and see how that works. The next step is VERY important though... Whatever you do, don't forget to put your phone in airplane mode before you throw it in the air or it'll just fall right back down after a couple feet... Keep it in the air I always say.

Im hoping once I hit 88MPH it will go back in time to when my phone actually worked. haha
I usually just use the Kernel that comes with the rom..
However I have used Set CPU and Voltage control together once. I messed around with the setting between performance and conservative.

Orion, first off. If u remember how "beepers" worked back in the day, if u ever had one, that's how text messaging works. It triggers a small ping when being sent or receiving message. So text messages really hardly use power. As far as ur battery is concerned, try this method if u like, just to see what kind of results u get. Charge battery completely with phone on first and then off. Then boot into cwm and wipe ur battery stats. Then drain ur battery completely without charging it. Then completely charge it up, and then see how ur battery does.

One more thing. Anytime u change rom or kernel, update ur prl and profile, then reboot ur phone..it does make a difference doint this.

True, just don't wipe your battery stats too much, it could end up doing more harm than good. But good call, I overlooked that cuz I was being a smart ass lol... Please don't throw your phone, that's never a good idea haha.

Were you overclocking when your battery life sucked? What uses more gas, riding at 55MPH or 90MPH? What was your battery life like on custom ROMs with stock frequencies?

Battery was ok when I overclocked.. went down hill after that. Except whenever im on stock EI22 Gingerbread and it runs all day.
On custom roms with stock frequencies I would still see a significant drain.

I don't think you fried it if it's still running fine on stock. I'd be more likely to think you're overclocking with an aggressive governor that is making your cpu stay at higher frequencies.

I havent been doing any OC or UV in months now and still have the problems on custom roms. Perhaps I got the phone that doesnt like to be modded.. Damn Sprint ha

also screen brightness has a HUGE effect on battery life. also do you do games and such? Those can be very draining as well. I am on a viper rom going on 14hrs and still at 78%. but i mostly text with my phone. about 15,000 a month to be exact. and use f.b. and xda pretty heavily. and different kernels can make the difference between 6 hours and 20.

i will say that my phone is particular on what rom i do run no matter what kernel i use

I just mainly text and surf the web occasionally. Funny part though the only game I play rarely is Deer Hunter Challenge which is a pretty high def large file game and when i play that my battery doesnt seem to drain. Right now Ive gone down 10% over the last hour just sending about 15 texts. And I have my display set to auto brightness

It's real simple...overclocking equals faster cpu AND faster battery drain. Do not overclock or do not complain about battery...one or the other.

[Q] Worse battery life after installing DoomKernal

I'm using FPSE playing FF7 as the test.
Before installing DoomKernal I was getting a drain of about %13 per hour.
After Installing DoomKernal I am getting a 24% battery drain per hour.
I thought DoomKernel was supposed to help battery life. I even cleaned up the running processes. So they don't drain the battery in the background.
I have installing SetCpu but I haven't overclocked, I only used it to set the minimum speed lower.
I have JuiceDefender set to disable connectivity when using FPSE.
Am I doing something wrong?

try fully charging then turn off phone continue charging then boot recovery and press wipe battery stats.
Sent from my R800i using Tapatalk

Not sure which kernal your using with 10 i get nearly as good as stock, so close i leave it, where in the past ive tried them and always gone back to stock
If its V11 i think from memory the GPU is overclocked and in his thread he does state that the effect of this on battery is unkown.
When i say as good as stock i mean at comparable set speeds.

using v11 now, no significant difference than previous one...

I use DoomKernel v10 and battery life is excellent. I use different governers based on what I am doing.
Like smartass and underclocked to 400Megs during night and 1G or 1.2G during and gaming with OnDemand.

Tried DoomKernel v10. Went back to Advanced Stock to emulate the original conditions. No significant difference here between both kernels.

Well I don't know why then. I used the latest one available at the time.
When I tried it, I wasn't overclocking or anything. Left things as is.
I'm now using Cyanogenmod 7 with it's kernel, and I'm getting same/slightly better battery life than stock. But when I was on DoomKernel, battery life just sucked.

I'm really sorry for it, Masters... I guess there are too many variables to understand. Maybe it's a slightly different phone, maybe our modus operandi is different (i proably drain more battery than you, based on your posts).
Anyway, I hope you can find a solution, or maybe in newer versions it will be better. For now, sorry I can't help.

[Q] what is the best battery saving kernel?

hey guys, i am looking for a kernel that will save me on battery. i am running zombie 4 rom. it says it runs the dark x kernel. i don't need to be running at super speeds but i don't want screen freezes either. i just want to be able to play my satellite radio without the phone draining 3 percent every 5 min or so. any help would be great.

I would be interested in this as well. Currently I am Rooted and have tried a few ROM's but haven't found one yet that doesn't have some bug or another. {Granted, I haven't tried them all} Tried one ROM that really distorted my custom made Wallpapers, which is a big deal to me. So... yes, any info on a better battery life Kernel would be welcome.
Currently I am not a "heavy user" on the phone. Talk - Text - You Tube occasionally... that's it. Constantly looking for better ways to improve this already amazing phone.

Eugenes kernel has given me great battery life. Either get down with Eugene's Macnut ROM which already has it or search for it under the general section under the bounty thread for Eugene. Its in page....58?
Keep in mind that the "beta" kernel does not have bln support but works just fine so long as you use the lionheart governor.
If you can't find the bounty thread then I'm sorry for you.

Synergy kernel has been awesome on battery for many.

How you use your phone determines the best way to get the best battery life. Basically there are two ways to save battery: cutting power when not in use and delivering less power to the processors.
If you use your phone intermittently throughout the day for texts or calls, you'll get the best battery results from kernels/ROMs/apps that cut unnecessary functions when you're not using the phone. For example, juice defender cuts your wifi and mobile data when your screen is off and reactivates it every 15min (can be configured otherwise) to check for notifications. Darkside's Digital Warfare utilizes something called "deep sleep" which actually completely turns off your processors when the screen is off, but keeps the basic cell radio on so if you receive a text/phone call it will wake up the processor. These functions have the largest and safest impact on battery life.
If you're constantly using your phone and you want better battery life, you basically only have one option: undervolting. This is essentially supplying less power to your processors, which can be done through system tuner. It's not a free ticket, however; if you undervolt too low then at higher frequencies (playing games, etc.) your processor will become unstable and your phone will randomly reboot. If you encounter this, then don't undervolt that much and up the voltage to the last safe level. Just for reference, undervolting by 50mV is usually considered safe and undervolting past 100mV usually results in boot loops. But how far you can actually undervolt depends on your individual phone hardware, there's no universal answer. Make sure to not set your undervolt settings to set at boot until you find a stable voltage. Otherwise, you'll be forced to restore a nandroid if you encounter a bootloop.
TL;DR
If your phone already lasts a day and you want it to last 2-3 days, look into ROMs/kernels/apps that cut unnecessary functions when not in use. Most effective way to extend battery.
If your phone lasts 8 hours and you want it to last a day because you're a heavy user, look into undervolting with system tuner.

Why do I get horrible battery life with ROMS and Kernels?

I've used cm9 and aokp the past month and tried the stock Kernels that come with it and Franco's. One thing is for certain. No matter combination I get horrible battery life. If I run stock android with my extended battery including various Widgets I get 24 hours battery life pretty easily. Moderate usage and some heavy usage. With cm9 I'm getting maybe 15-16 hrs with aokp maybe 8-9 hers and I'm using Franco's kernel right now. I don't understand this. People talk about how much better the battery life is with various ROMS than stock but I'm not getting it. I'm getting like half the battery life I was before. Any ideas?

I can relate to you. Was in CM9 and Franko's kernel and as you said, horrible battery life. I went back to stock but this time I did not install apps thar would require services running (well I have to run WhatsApp so that's the only one running besides default abdroid services).
I am seeing better battery life this way.
The next step would be to install CM9 and restore all my apps to see if I can replicate the same battery life.

you need to find out what apps are keeping your phone from sleeping dude its not the ROM or Kernel if you want to find out you can use better battery stats or just read the permissions on your apps otherwise its probably cause your on your phone too much with the screen on first show use a usage screen shot then how many apps you have we can narrow it down

I used that better battery stats app and apparently there was audio something (sorry can't remember the exact words) causing partial wakelocks, read some google search results and disabled the lock screen sound in aokp and it went away, go figure?
I swear my battery life is better with the kernel that comes with AOKP rather than franco, which was a bummer since I'd just bought the franco updater app, perhaps just my imagination or maybe something just needs to be tweaked

Well, this has pretty much nothing to do with the ROMs/kernels, you flash to the device. If you use the device for heavy gaming, you use loads of apps etc. the battery life will obviously be bad, because the CPU needs the according CPU clock speed...
Underclock the CPU, or better: Get AnTuTu CPU Master pro, and set the profiles, underclock screen off, to 700 MHz, and every other proile, where you do not neccessarily need the device to that speed, not below, otherwise it will just crash... That way you have the best battery life, for your usage, so basically, every time you switch the device's screen off, it will save a hell of a load of battery

Under clocking doesn't do much for battery life contrary to popular belief. It just increases the time it takes to process a task. It might take 1s at 1.2ghz vs 1.8s at 800ghz to complete a given task for example. So yes the cpu will run at lower speed and voltage but it still also take longer to return to idle.

Well, I don't really mean to break this, because it is right, but not completely...
Underclocking & undervolting, when the device is not in use (Screen off) saves loads of battery...
And because it's a dual-core, it takes mostly just as long to open an app at 700 MHz, as when you're doing it at stock clock speed, or voltage or higher.. So, in that case...

Not sure how this wouldn't have to do with the different ROMS and kernels since I stated what battery life I was getting with stock vs using a custom kernel and ROMS. I'm giving a comparison of my battery on each with the same usasge and they are different.

battery runs out fast while using phone

hi all,
I recently switched from stock rom with root, to pure nexus rom and ElementalX kernel.
the reason i changed the stock rom is because of battery drain while phone is asleep.
the wakelock detector showed that the play store and google services kept it awake.
now the awake percentage is much better, but it seem like the battery runs out faster when i'm using the phone.
the battery can loose 1% an hour asleep, but it seem like every time a touch the phone it looses its power really fast.
does it make any sense?
should i just admit that the 5x battery just isn't enough for me?
i'll be happy to hear you advice,
thanks

I agree phone does drain fast whilst using the phone I can't get a full day of use with this compared to the iPhone 6 I had

Maybe you guys need to look at some of the apps you run? Facebook and messenger are known to cause these issues, there are alternatives but it may be worth a try.
I have no issues with my phones battery and last a day no problems.

I can use my phone all day at like 85% brightness and then not charge it overnight, wake up the next day and still have enough battery. Usage differences aside, the things you should be looking at are the kinds of apps you're using and the way you have your kernel configured. As suggested previously, apps like Facebook and Facebook Messenger are widely known battery killers (Metal is a good alternative). Make sure you have adaptive brightness on, the screen is, by far, the biggest battery drain. Lastly, but more importantly, configuring your kernel and cpu governor would really help. I know you said you're running the ElementalX kernel, which is a fantastic kernel. I'd recommend getting the ElementalX Kernel Manager app from the play store and using that to tweak the kernel to your liking. Specifically disabling Touchboost and trying some of the tweaks in this thread. Touchboost is a battery killer as well and rarely effects the fluidity of the phone. The tweaks / profiles in the post I linked are an easy way to apply different values to the tuneable parts of a CPU governor. These values effect things like what frequency the CPU is at under a particular load, the input boost frequency (the frequency the CPU jumps to when you interact with the screen), and generally how the CPU behaves. In most cases, users have reported a nice bump in battery life AND performance. Some people are reported achieving over 6 hours of Screen On Time on a single charge. If that doesn't get you through the day, then idk what will.
The battery in the N5X isn't huge, but it isn't tiny by any means. It really depends how you use your phone; everyone's different. I highly recommend doing what I said above, it'll make a huge difference in your device, I promise.

Would highly recommend AT LEAST getting a different kernel and following the same recommendations I made above. A different ROM that's optimized with UberTC helps with overall responsiveness and battery life slightly as well.

Hi thanks for the advice much appreciated I don't run apps like Facebook and Twitter not a fan however I will try a custom kernel and see if that makes any difference
Thanks again

when i'm not using the phone the battery consumption is OK, my problem is with the time i'm using the phone, so i think tweaking with the kernel setting may be useful... i'm trying to use free apps only, but i may consider downloading the ElementalX app if it turns out useful.
Regarding the screen - is auto brightness is a battery saver?

The EXKM app has a number of good CPU governor profiles Built in.
I think it's really worth the couple of bucks.
Also if you're indoors mostly you can probably keep the brightness at 10-20% instead of auto which really helps with battery life.

I bought the elemental app last night and installed the elemental kernel before my phone used to say 8 hrs of battery remaining after installing the kernel it now says 2 days remaining what a difference I've kept auto brightness on disabled touchboost and I'm using the butterfly profile
Thanks for all the advice people
Sent from my Nexus 5X using Tapatalk

bought it too
so,
when you say use butterfly,
you mean you enter to cpu->governor options,
you load the profile for both large and big cluster,
and makes it "apply on boot"
thank you all again
