Serious Battery drain - Kindle Fire Q&A, Help & Troubleshooting

Hey guys this is my first posting in the kindle section so be nice. I flashed hashcodes cm10 on my girls kindle like 3 months ago and she is having major battery drain problems like from full charge to dead on a day just from stand by. Is there anything I should look into like settings wise or another rom. She just wants a rom that is compatible with an external keyboard. Thanks guys and girls

CM7 is a good choice if you are concerned with battery life. sblood86 has on available somewhere in the development forum. Check the development index stickied at the top of the forum.

Latest CM10.1 is way better

It's normal for that generation of ROMs. Feel free to install ROMs with latest Hash's kernel, it's not draining more than 1% during the night stand-by. I can tell You for sure that Twa-priv's ROMs are working with external keyboards, assume it's the same with all of them with same kernel.

Alright thanks guys

Best ROM and kernel for Gnex

sorry because I'm new to Gnex, but I need some recommendation about the best ROM and kernel combination for battery life.. I'm now on stock 4.04 ROM & kernel.. •thanks if anybody can help me answer my question

I'm running gummy 101 and leankernel 340, nice and fast and i get anywhere from 12-24 hours on the 1850 mah stock battery
You touched a very sensitive part of gnex
Gnex battery sucks and everybody knows it
But all you get is an answer that: battery life for different users on a same ROM+kernel will always be different.
But I will tell you a secret No matter what rom or kernel you will use, you will still need to charge it overnight
Mine setup stock rom + franco kernel. Tried different kernel settings and seems that all I got is maybe +1hour of standby time. Screen time didnt increase a minute.

screen time refers to the time your screen is on. standby refers to the time your screen is off.
I am using the same combo as above - stock 4.0.4 ROM + franco kernel 3.0.8 M3. I am getting about 4 hours screen on time + 12-14 hours standby time with heavy usage.
i would also recommend you to install better battery stats and cpuspy to weed out any rogue applications preventing your phone to go to deep sleep.
I'm running winner00's cyanogenmod kang with the 551 Franco nightly, seems to be a very stable combination with pretty decent battery life.

Battery is mostyl kernel thing there i would prefer franco.kernel latest milestone is great for battery life if you are friend of testing you could install latest nightly. All explained into his thread in Developer section.
As stable ROM testing AOKP Milestone 5 release some days ago and it is very stable i think. It was also my first rom some months ago.
If you want compare this roms you should look into the threads, very helpful for me at begining.
Liquidsmooth is very clean and small only 80Mb compare to 140Mb they smalled the code an tried to be fastest an clean. If you try the latest release you get franco kernel milestone 3. Many users prefer this stock-kernel combination for battery life. But remeber it is only in english language if that is no problem try out.
If you are familar to testing something look at latest nigthlys from rom and kernel and testing it out.

This is strictly a taste perspective. I am running Banf Paradigm 1.25 with the Jame Bond Kernel. Pretty sweet.
These threads need to stop. There's one of these daily. Invest some time into your phone and just flash the **** on your own and find one that suits your needs and demands. People love to play the noob card but its just pure laziness.

sorry if u think that this thread is useless, and u say u see it daily, but a newbie like me think that this thread is very useful because I can get information before flashing any rom and I had searched for at least 5 pages in the Q&A and got nothing so I started this thread.. and I'm asking not because of laziness, but not every people like to download everything like u do, especially for low speed internet users.. and this is a Q&A thread that is made for this.. so I don't think I'm wrong asking here.. good day

What is the best JB ROM for best battery life?

Hello everyone, in a month I'm getting the s3 and after coming from a Motorola defy, I know battery life won't be as good. I see there are a ton more JB ROMs for the s3 than the defy so I would like your advice for the ROM with best battery life. Also, the defy has no custom kernels so I'm unfamiliar with how they work. Any advice?
Sent from my MB525 using Tapatalk
I would say there isn't a good answer to your question until an OTA JB official is released. Right now are just leak based or CM/AOSP based and very few of them for t-mo are very stable. There are a few kernel mods that will give you ability to undervolt or underclock, and that is best bet at battery life.
Basically the screen and radios will eat up your battery no matter what, but with screen off in various sleep states, if you put WLAN to sleep, it can last a very long time. The best solution is to invest in a USB external battery pack probably.

They are all pretty much the same IMO. The screen sucks up juice so keep it off as often as possible lol

If you want the latest software, most stable, and best battery life ROM, go with MMuzzy's AOSP ROM. Using it now, and its amazing
Sent from my Galaxy Nexus using xda premium
ROMs themselves rarely ever have an actual impact on battery life. Most postive effects for battery come from the kernel, and negative ones from rogue apps.
Before you ask which kernel offers the best battery, it really depends on the requirements of the user and the phone itself. You'll just have to try a few.

Flash it like you would a ROM. Make sure you find one that is for the version of android your ROM is based on. I would suggest tying Franco kernel, but there are many good ones.

FYI....this thread goes in general.
Flash kernel in cwm the same as you would have a rom. Be sure to clear cache/dalvik first.
For the moment the ROM with the best battery life is SlimRoms 2.7

I've tried many ROMs and Kernels with no success in the battery life department.
My phone charger died so I downloaded an app...Easy Battery Saver...my phone was still at 34% after 1 day and 7 hours. I was NOT heavily using my phone but still this is the best battery life I have ever experienced. I was always on the "battery saver apps are useless" team until recently.
Don't get me wrong, I'm still flashing
Just love my new app.
i tried miui, pa, vicious, aopk, smooth, and now using cm10. tried out different kernals too,but at the end, all the roms cant pass 1hr 50mins of screen time.

Hmm.. thats strange. I'm on MMuzzy's ROM which is pure AOSP and I get around 2 and a half hours of screen time. And some people around the forums have gotten around 5 hours of screen time with different combinations of ROMS and Kernels.
I have tried numerous roms, if not all of them for the galaxy nexus, and there is a difference between roms, even using the same kernel.
I have been getting amazing battery life using Eclipse.

The mods can move this thread, but in the mean time, it is a good question.
I used to get some awesome battery life. VZW + 2100mah. Typically 4 hours screen on time was normal.... now I'm lucky to get 1hr. I can't remember if it was the jelly bean update or the inclusion of Google Now.
Does letting the ROM settle really help? I have been getting terrible battery life out of my 2100mah. The battery just drains when the screen is off. No rogue apps, but this is a fresh install as of 24 hours ago

I believe use what you like as long as you use Lean Kernel you should get good battery life.

I wasn't going to put my 2 cents in but because there are so many complaints about this being in the wrong place, I just have to now.
I have tried many different ROM's and kernels and found there always seems to be the "right" combination sooner or later. Right now I am on AOKP w/Franco M6 and getting about 14 hours with 24% battery left, 2.5 hours screen time, mostly LTE and moderate phone use, best I have seen of any combo for me on this ROM. For CNA the right kernel for me was lean kernel. A little experimentation and patience and you will find that sweet spot soon enough.
Edit: the whining drew me to it, sucked me in so I couldn't stop myself from answering
If someone can get 4+ hours screen with mostly 3G, let me know. haha.
Wrong section
However as for battery life slim ROMs work great but I'm on jbsourcery built in trinity and I've definitely had worse d: the only ROM I've used that's had has battery is pa however they've had multiple updates since then so I'm sure its not horrible now

2 things here:
1) OP, wrong section. Questions belong in their own section, the Q&A section. Development is reserved for Roms, kernels, tweaks, etc.
2) If you guys see something posted in the wrong section, report it. No need to get in an internet gang war about it. Us mods have a life too and we can not be here 24 hrs a day to watch over you. When you hit the report button, we see it.

Most stable rom

I usually hate threads like this but I have a question to keep my sanity.
So I am getting a kindle fire for a friend, I am looking for something I won't have to constantly be fixing it for things other than small normal stuff.
That being said there are only 2 qualifiers with this:
1. Needs to be AOSP based
2. And I'd prefer it to be CM9 or Newer
And this sleep of death thing scares me ( yes I know reboot fixes just not trying to deal with it)

I have found that ICS ROMs run best on Kindle Fires. I currently use twa_priv's CM9 rom and I have no problems with it. And battery life is pretty good.

When the first Kindle came out my girlfriend insisted on getting it. Worked okay at first, but quickly became unstable/broken. She asked if I could do anything to make it better. Loaded several custom roms and she always came back saying it was the same story. Worked okay for a few days. Most often the browser randomly closes. Sometimes as soon as you open it.
I've been unable thus far to find something that is reliable.
I am going to give your suggestion a try.
I've been using CM 10.1 for a week now with zero problems. I mostly use it for games, but also Browsing, Flipboard, Netflix, and various other apps. No issues other than the battery drains faster than it did stock. But that was expected.

Carbon nightly

I put this on my device yesterday and very glad that I did.
Previously I had Hellybean, and cyanogen 10.1.3 on phone. Helly crashed too often and cyanogen was a battery hog. Plus, cyanogen is not nearly as stable as one would expect from it being such a popular Rom.
Butt I've found that carbon has all the right tweaks, battery life, etc etc.
Any thoughts on this Rom? Should I be updating it daily since it is a nightly our can I just stay with the one I have right now?

firstly, this is the wrong thread to ask something this thread is specific for development purposes, asking questions about a rom in their specific thread is ok, but for general questions there's a different part of this device's forum
secondly, its not needed to update on a daily basis, nightlies do tend to fix some sort of issue or bring some sort of improvement to the rom, its basically depending on what has changed (see the changelogs for that) in order to decide to update or not.
If the rom works as it should, then just update whenever you feel the need to update, but what i mostly do with roms like pac and such who release a new nightly every day is to download it, wait for a while and see if anyone starts complaining about issues coming with the new release, if there's none i simply flash it myself. And sometimes i simply don't feel like updating it every day and i'll wait a week or so (depending on if i'm still on that rom or if i'm trying out a new one )
nightlies don't necesarily mean that everything works as it should, instead something might get broken while something else has been fixed.
speaking of cm, there's a lot of custom roms a lot more stable than cm is, and i'm honestly not expecting for that rom to get any better with a lot of the devs leaving and starting the omnirom project
i do have high hopes for omnirom though
I'll check out ommirom.
I didn't see any listings for a section specifically for Carbon ROM. If you have a link that would be awesome.
