Check the frequency of updates on all of your accounts settings. If you don't use the Facebook widgets, turn off the live updating. For contacts updating on Facebook, if you use it, change it to once a day instead of every three hours. If you aren't using Google News or Stocks, turn off the updating on those entirely. Check the frequency on your weather checking. If you're having it do automatic backups, see if is is once or day or multiple times. Pull it back to once. Drop your screen to about 20% when not necessary to have it brighter.
