Hi, Since few days I find my mobile battery gets drain very quickly (around 10-15 mins in use) and also its gets charged fully in 15-20 mins. When I keep the phone idle it last for 2-3 hrs.I have updated Adroid 2.2 (Froyo) to 2.3.4 few months back through internet after following one of the forum. My mobile is exactly one year old. Could anybody suggest why my mobile battery gets drains quickly. I have checked all the optimum setup for less battery usage. Do I need to change my battery? Also I am not able to connect my phone with Kies. It keeps on displaying "Connecting"
