I have a Storm 9530 running on .419. Every time I use the browser, it goes nuts: my battery just drains (last time I surfed two sites, for about five minutes, it went down 20%); my screen won't recognize my thumbs ever again, and Berryslider becomes a nightmare. I need to do several Quickpulls and battery removals to get it back to normal.

Other information that might be useful: other than the native software, I have Gmail, Quickpull, Google sync and Berryslider. I tried the Opera browser, but didn't convince me so I deleted it. As with every other software that I have a shot at: the Facebook app, the BlackBerry app store, etc.

Any hint?
Thanks a lot!
