Same here.After I`ve upgraded to the v50 kernel phone was unstable, even with conservative settings.I`ve tried and uninstalled the v.6 battery patch and overclocked to 900 with the ideal kernel and let me tell you, my phone flies again.I don`t know about battery life but because I had batterypatch for so long I`ve forgot how responsive my phone is without it!I might try and install it again in the near future when it`s more stable.Thanks for your work
