Limit CPU Frequency to Save Battery
이건 cpu 클럭을 다운시켜서 배터리를 왕 세이브 시키는 방법입니다.
어느 정도 내려도 쓰는데는 그렇게 지장이 없고 배터리를 엄청 여유 있게 사용 할수 있다니 한번쯤 해보는것도 좋을거 같네요.
As you may know, I have a thread about a modified ramdisk kernel to save battery, but I don't want to release 3+ versions with a new kernel every week, so here is a solution which doesn't require flashing, and can survive OTA updates, etc.
- You need to install an init.d emulator, like Init.d scripts support. 다운받으세요. 밑에 그림과 같이 세팅
- Start it, tick acquire root.
- Go to Home Screen->Tools->Security->Root permissions, enable it.
- Go to Home Screen->Tools->Security->Autostart, enable it.
- Set it up like this
- Create a folder on your inner SD with name "scripts". /sdcard/scripts/limit.sh 란 파일 생성
- Create a text file inside it, with name "limit.sh", and the content: 1200000 이니까 1.2ghz네요Code:
#!/system/bin/sh echo '1200000' > /proc/cpufreq/cpufreq_limited_max_freq_by_user echo '0' > /proc/cpufreq/cpufreq_limited_by_hevc chmod 0600 /proc/cpufreq/cpufreq_limited_by_hevc
If you want 1.5GHz, change the first number to 1500000- If you want touch boost, remove the last 2 lines.
Touch boost immediately boosts the frequency to a given state (usually close to the highest) when you touch the screen.
I didn't notice any slowdown without it
.
That's it, now you don't have to worry about flashing or OTA updates.
폴더 경로 지정해 두고 run scripts now 누르시면 됩니다.
그냥 usb 연결해서 파일 보내서 실행 해 주셔도 됩니다 sdcard/scripts 에 보내면 됩니다.
