I got it installed on a stock fresh rom and installed the update but nothing is getting better.
Still battery is flying out of the window like anything and I am unable to use it for a day or so. Thinking of selling this and better to get a HTC or Asus.
No improvement in the last update. One thing I don't understand was the battery life after putting the Airplane mode on and turned off the GSM network.
Battery goes down like anything when using Wifi and keeping the GSM on, but as soon as I put the airplane mode the drain stopped. I had drained 10% of the battery in 15 mins while surfing, but the phone which had 4% while i put in Airplane mode stayed there for 8 hours without any decrease!
Is that the GSM network module or something is going wrong?
