Tweak your rooted android device with build.prop

Hey everybody, just wanted to share the below build.prop performance tweaks. I have been using them for some time now trying different values to see what works the best. General Performance debug.sf.hw=1 Edit existing line, dalvik.vm.heapsize=48m persist.sys.ui.hw=1 Faster Scrolling ro.max.fling_velocity=12000 ro.min.fling_velocity=8000 Saves power ro.ril.disable.power.collapse=1 pm.sleep_mode=1 windowsmgr.max_events_per_sec=60 wifi.supplicant_scan_interval=180 *If you don’t keep Wi-Fi active lowering the value below the default of 90 seems to make Wi-Fi connect faster after being turned on but will consume more power if turning Wi-Fi off has been forgotten when not in range of a known network. ro.mot.eri.losalert.delay=1000 *Should smooth out disconnects and reconnects, saving battery. Seems to brake tethering with CM7, let me know if anyone else experiences this issue. Raises quality of images ro.media.enc.jpeg.quality=90 ro.m

Qualcomm MSM Chip-sets

Most HTC devices have at their core Qualcomm System-on-Chip (SoC) Mobile Station Modem (MSM) integrated circuits. These are based on Advanced RISC Machines Ltd. (ARM) micro-processor and supporting systems designs. In most Smart Phone devices the SoC consists of two ARM micro-processors, one to manage the communications hardware (radio transmitters) and the other to manage the user applications and interface. These are generally known as the modem (or radio or baseband ) processor and the applications (or apps ) processor. These processors may not be identical since their functions are different. Peripheral Communications The MSM SoC contains a large number of integrated controllers and peripherals, all of which need to communicate with one or all micro-processors. Data Mover Direct Memory Access (DMA) controllers set-up and supervise direct transfers of large blocks of data directly to or from a peripheral out of or into Random Access Memory (RAM). DMA releases th
