Phone was running smoothly until the 2.6 update after 2.6 update os started to worsen. Everything was tolerable untill the battery drain started one week before. The phone heats on top portion that is around the earpiece when I start to use network. The temps will be always 38-42 all the time when we use network. And the battery draining. Iven if I won’t use the phone, the battery drains quickly. Idle drain is not showing in the battery usage stats but during night the draining is about 20-25%. I have turned off everything and turned on battery saver was the only option which decreased the draining to 10%. But even it’s too much. Need more optimisation for the idle drain. Please consider this on 3.0 update .. I have seen a lot of people complain on the draining issue.
