Really happy with it. I’ve got a larger Mugen battery in and I use juicedefender. Been running v18 since yesterday and it’s just hit 24 hours and still a quarter battery left. Also turned off google now as i rarely use it and use the fastdormamcy toggle (off) and turn off google location services unless needed. Stability wise its solid. No crashes or lockups and been using Temasek since v1.
Oh and use the Banks Gapps package with it (about 70meg).
Was a big fan of CM but really happy with Temasek’s so far. Give it a shot. The worst that can happen is you switch back to CM if you don’t like it. The beauty of custom roms with android!
