[LG Optimus 3D] Pät:
Hello O3D Users,

I just have switched from my Xperia neo to the O3D, but before buying it I have checked this Forum.

I have noticed that most of the people here keep complaining about the battery life of the O3D. I have been heavily using my mobile phone now and the battery life isn't that bad at all!! So i started this thread to gather tweaks to extend our battery life.

1.Root

First of all you will need to get root to be able to make changes to your O3D (see Link below)

2.CWM

-After getting root i would suggest to flash a custom rom, since most of these are heavily optimized and tweaked.

for that you will need CWM (see link below)

3. Custom rom

Choose and flash a custom rom/kernel, dont forget to backup your phone before

-after flashing a lot of custom roms, you should reset your battery-stats. Charge your phone to 100% -> reboot into recovery -> advanced -> wipe battery stats -> recharge your phone to 100 again.

4. Optimize your phone!!

-Install Linksd ( https://play.google.com/store/search?q=Linksd ) and freeze/deinstall apps you dont need (A lot of preinstalled apps keeps running in background). Just check in system -> running apps which apps you dont need but keeps running in background and freeze them.

-Install easy batter saver ( https://play.google.com/store/search?q=easy+battery+saver ) and check in the menu "consumption" which app is draining a lot of battery% and try to replace it with a similiar app or get rid of it

-(Maybe we can start a bloatware list here but i will need your help for that)

5.

Underclock/Ram-management/Govenor

-Its always usefull to underclock your phone, because this will save your a lot of battery: I have my phone underclocked to 800Mhz normal use and 300Mhz while screen is off.

-If you are using a custom rom you dont need to take care of Ram-management, if not and you have installed a Ram-management app you should NOT use presets like very aggressive or aggressive. (They cause more app reboots -> more battery usage)

-Choose the Hotplug Govenor. It is the govenor from Lg and our phone run the smoothest with it (also most custom roms have tweaked this govenor).

6.

Sysctl tweaks, Vm heap size and Kernel tweaks:

-Install System Tuner ( https://play.google.com/store/search?q=System+tuner ) go to SysCtl -> recommended

-Install Rom Toolbox lite ( https://play.google.com/store/search?q=rom+toolbox+lite )go to Performance -> build.prob tweaks -> increase Vm heap save and reboot. Repeat this process up to Vm heapsize 124

-With System Tuner go to CPU-> Boot Settings ->Govenors behaviour -> and if your are using an Ondemand governor set Power-save bias to a value like 30-40.

7.

Other useful informations/tools

-Widgets: They are very useful for many apps, but widgets keep running in background. So if you don`'t really need them, replace them with an app-shortcut.

If you are using a Widget check if there is an Refresh-Intervall (Weather widgets) and set the intervall to a higher number

-Install easy battery saver. Its a great app, it calculates remaing battery capacity, shedules your data-traffic and monitos also battery usage of different apps.

-keep your Screen-Brightness in the lower end.

- turn wifi/gps/bluetooth off when you are not using it.

-2G network consumes less battery then 3g and data connection consumes less then wifi.

-don´t install apps you dont need/use or try to install an app that can do various things (For example Rom Toolbox can block ads, underclock your phone and manage your ram or easy battery saver)

-Live-wallpaper looks nice but consumes more battery and (i think) that a dark background consumes less battery then a bright/colorful one

-get a micro-sd card with higher class (like class 10)

I hope we can gather more tweaks here and create a Bloatware list.

Credits go to the developers, which do a rly great job!
