i have my proclaim rooted, and since rooting i've made some changes that have increased my battery life and performance. right now, i am using no-frills CPU control with the following values: Max clock 1.0 ghz Min clock 1.0 ghz Governor Performance I/O Sched noop i used quadrant to benchmark and found that the "noop" scheduler provides the best results for i/o and CPU performance. contrary to popular belief, running your droid at max clock all the time will not cause the battery performance to degrade, it will actually improve it -- the CPU is not wasting clock cycles monitoring load and adjusting it's speed so you'll notice a more snappy response from your droid. the battery improvement stems from the fact that at the higher clock speed, the CPU finishes tasks more quickly and then goes back to sleep. a 1ghz CPU in sleep mode and a 100mhz CPU in sleep mode use the same amount of power... they're both asleep and not processing. you'll also notice smoother performance because the phone won't have to waste clock cycles adjusting its speed. you may notice a slight lag when you first start scrolling or doing something like that, this is the lag while the CPU is ramping up. yesterday i took my phone off the charger at 100% and left for the day. with moderate internet browsing, moderate to heavy texting, and some music playback, when i got home 12 hours later, my battery was only at 75%, which i think is quite good. that's including about 2 hours screen time @ 30% brightness. performance and battery life also improved after i removed every unnecessary service and software package i could find. i backed up and removed the following items: AccuWeather.com AllShare Analog Dual Clock Analog Clock3 AnalogClock4 audioTuning Aurora Blue Sea Bluetooth share (i don't use bluetooth and never plan to, don't remove this if you do) Bluetooth Test (i don't use bluetooth and never plan to, don't remove this if you do) BrcmBluetoothServices (i don't use bluetooth and never plan to, don't remove this if you do) Browser (don't remove unless you have another browser installed) Car Cradle ChocoEUKor com.sec.android.app.lcdtest com.sec.android.app.screencapture CoolEUKor Digital clock Digital Dual Clock Downloads DRM content (i don't have any DRM'd music and have no problems with music/notifications/ringtone playback, don't remove if you have DRM music) Email (i only use gmail, this is pointless) EncryptApp Error Factory Test FactoryTestService Gallery (i use quickpic instead) Google backup transport Google calendar sync Google Contacts sync Google play books Google Play music Google+ Home screen tips (if you're rooted, you probably don't need tips on how to use your phone) HTML viewer KeyboardCountUpSlider (counts how many times the slide is opened, this phone isn't even a slider, so pointless...) KickBack Live Wallpapers picker Maps Market Feedback Agent My files (i use root explorer instead) My uploads (for u/l to youtube, i don't use it) Network Location OPP (i don't use bluetooth and never plan to, don't remove this if you do) Pico TTS Preconfig Program Monitor RoseEUKor Search Applications Provider Slef Test Mode Service Mode Setup Wizard SNS (more social networking crap) SNSaccount (more social networking) Sound Player SoundBack Sparks Stealth functionality test swype talk TalkBack TTS Service TwLauncher (don't remove unless you have another launcher installed, i recommend holo launcher) TwWallpaperChooser Unable to play. No available licence (idk wtf this is, but they didn't even spell license correctly...) Voice Dialer Voice Search VVMService Wi-Fi Sharing Wi-Fi Sharing Manager Wipeoutreceiver WlanTest wssynclnps if you don't know what it is or if you need it, don't remove it!!! and of course, always backup with titanium backup first, just in case. if you want more information about any of these services, feel free to ask and i can elaborate or clarify for you. i haven't noticed any issues with this configuration -- phone, sms/mms, 3g, wi-fi, etc. are all working and i've had no FCs, not a single one. YMMV, but i spent a lot of time researching these components and what they're used for, and i spent days removing and testing them before making this post, so i'm fairly sure this is a good, stripped down, stable, performance-minded configuration. questions and comments are welcome, and again, i will gladly elaborate or clarify if you need any questions answered.
