Hmm on the 11/25 build I also experience weird battery drops. Also the battery life in general seemed to last longer on the build before, second last. Maybe I switch back to that one.

Hmm on the 11/25 build I also experience weird battery drops. Also the battery life in general seemed to last longer on the build before, second last. Maybe I switch back to that one.
what build you don't experience battery drop? and also what is the other issues on that build? maybe i'll downgrade to old build if battery drop issue will fix that build.

Hey Sultan, I would like to improve your ROM by pointing out some mistakes/features missing. First, I came from ARHD, which had a very comfortable feature, the ad remover. If you could implement some kind in yours, that would be great. Also, for some reason my dolphin browser scrolls very laggy, but it is probably individual problem. The more important to talk about is: speaker. Back in ARHD I could boost my bass up to max without serious distortion, but in your ROM there is a new equalizer (with 6 band 16Hz being the lowest, weird...) and it does distort sound when I set 250 and 62 Hz bands to max (not to talk about bass booster). Personally I prefered the old eq system for both speaker and headphones. But there is something interesting stuff with the speaker as well. The ROM seems to think I am using 2.0 or 2.1 speakers, because after listening to some music, I realized it plays only either the left or right channel. Could you fix it? Apart from these drawbacks I'm really loving this ROM, and appreciate your work, Sultan!
Have a nice day!

i have solved the biggest part of my battery drop by disabling sync. I just notice a slight but decent improvement of my battery life by dropping cpu voltages. Ill try calibrating my battery and post back my results.

There is only two builds in the download map, the one of 16 nov..
Installed it again, check tomorrow when fully charged.
the video recorder in camera i guess have high bit rate that a 2 minute video have a size of 208mb. i guess this one has fix don't you guys?

CyanogenMod (pronounced /saɪ.'æn.oʊ.dʒɛn.mɒd/) is an enhanced open source firmware distribution for smartphones and tablet computers based on the Android mobile operating system. It offers features and options not found in the official firmware distributed by vendors of these devices.
Features supported by CyanogenMod include native theming support, FLAC audio codec support, a large Access Point Name list, an OpenVPN client, an enhanced reboot menu, support for Wi-Fi, Bluetooth, and USB tethering, CPU overclocking and other performance enhancements, soft buttons and other "tablet tweaks", toggles in the notification pull-down (such as wi-fi, Bluetooth and GPS), app permissions management, as well as other interface enhancements. CyanogenMod does not contain spyware or bloatware. In many cases, CyanogenMod may increase performance and reliability compared with official firmware releases.
CyanogenMod is developed as free and open source software based on the official releases of Android by Google, with added original and third-party code.
Source: CyanogenMod Wiki
Notable features:
- Uses 3.4.0 kernel based off of pure CAF KitKat sources (∞ thanks to Flemmard and shantur for their amazing fixes; read the 4th post for an explanation on what CAF means)
- 613MB of usable RAM
- Self-powered USB OTG
- Uses Ion memory allocator for everything: audio, display, video playback, camera, etc. (big thanks to shantur, Flemmard, and SebastiaFM for Ion camera)

- CAF Jelly Bean GPU drivers (from CAF branch jb_2.5)
- Hardware vsync
- No Maps 7 glitches, Google Chrome glitches, Browser glitches, Gmail glitches, etc.
- SELinux (Security-Enhanced Linux) enabled and set to Enforcing for better security

50Kernel features and details
This is a 3.4 kernel based off of pure CAF KitKat (kk_2.7-stable) kernel source with these features:
- Fully-synced with the latest changes from Qualcomm (CAF)
- 620MB of RAM
- WiFi drivers from Google's Nexus 5 kernel
- Display undervolting
- Basic color control (choose between regular and cooler colors)
- Lots of debugging garbage removed
- CPU overclocking up to 1.836GHz
- GPU overclocking up to 320MHz
- Full Ion
- Self-powered USB OTG
- More accurate battery percentage readings
- AC charge speed over USB (fastcharge)
- 620MB of usable RAM
- CPU-boost framework (boosts the CPU when the screen is touched and during certain strenuous activities)
- Display undervolting by up to 700mV
- Kernel-based thermald
- Basic display color control (choose between regular and cooler colors)
- Lots of debugging garbage removed
- No kernel modules (greater security)
- SELinux
34New build updated. Don't get too excited, I still haven't been able to fix any of the critical issues plaguing this kernel. Let's recap what's broken with this ROM/kernel:
- Incorrect CPU temperature is being reported (temps are reported as too high)
- High battery drain while screen is on
- Random shutdowns (might be caused by incorrect CPU temps being reported because a formal shutdown command is being sent; it isn't a true "random" shutdown)
- Issues with USB with some computers reported
- Phone gets too hot
- USB tethering completely broken
- Random reboots
30FAQ
What is CAF? What do you mean when you say that you have made a pure CAF kernel?
Answer: CAF = Code Aurora Forum. CAF is where Qualcomm engineers work to optimize the Linux kernel exclusively for Qualcomm chipsets. Device manufacturers use the kernel source from CAF to create kernels for their Qualcomm devices, but the code they get from CAF is always several months older than the latest code available on CAF. By grabbing the latest kernel source from CAF and adding Flemmard's Sensation drivers & fixes to it, I have created a new kernel that has all of the latest tweaks and optimizations from Qualcomm, and no major code from anywhere else.
