I've LG optimus 2x and I'm really tired and frustrated of Facebook and messenger app running in background.
1) it uses a lot of ram in my memory and phone is really slow.
2) It dries a lot of battery. Horrible. Yesterday I've uninstalled facebook app from my phone and I could finally use my phone without any single lag. First time in a few months that I use this phone, after that. Usually battery goes on 99% in about standby, now my phone is already 4h on standby and it's still on 100%. Finally phone works as it should be
So, question is, is there any good app or way to stop running these apps in background? I've already tried service disable but when I disabled some services app crashes and it was useless. So cross app disable and autokill apps.
