I recently got a brand new S3 and I am still having battery drain issues. I have turned off gps, wifi, all automatic syncs, i disbaled some bloatware i didn't use and was able to. I recently bought a brand new battery from samsung cause my battery was draining like crazy. I could charge the phone to 100 percent and then 4 hours later ( with no usuage!) my phone has dropped down to 60 percent. I installed better battery stats and it tells me android system is my biggest hog and names different apps ( i experimented and deleted each one off the phone pretty much all apps i had.. I only use very few as it is) Ive noticed samsung has all these bloat ware running and no way you can diable it. I did not have this issue until the new update. Anyone else have the issue with the new update? I wish I could get away from the update or something cause this is alot issues trying to plan how you going to plot to get to use your phone during the day.
