Any major update requires you to calibrate your battery as it reports erroneous levels. On the stock dialer, dial *#9900#, scroll down and tap 'reset battery stats'. Discharge completely before you recharge a couple of times, and when you recharge, try to charge continuously for 6 hours. Do three to four cycles of this, and you should be back to normal. Or if you want to skip the complicated stuff, just factory reset the phone and start fresh.
