Does installing a new launcher improve performance? Battery?

[orlanka]

There's a lot of gripes in the community about Sense and it's impacts on performance and battery drain. While I personally have no issues with it, does installing a new launcher essentially deactivate Sense? If I were to install something like Apex or Nova, what do I gain or lose besides Sense and some of it's widgets?

Thanks

the oly thi you wll be disabling with installing another launcher is the sense launcher itself.This could help save battery.
I recently switched from apex to nova and quite surpisingly noticed a bit less drain overall,not much but something after all.
If you want to get rid of sense completly you will have to unlock,root it and flash a aosp based rom which arent avaiable right now
