[babudpoa]

Hi all

I bought a Sedio 3200mAh battery for my tytn II (tilt) as i was really frustrated by the original battery, it doent last 4 hours of music or browsing, i thought 3200mAh, will be enough and it will give me atleast 10 hours, alas what a mistake, this new battery lasts couple of hours above the original battery, say 6 hours, and i have done the full charge and drain for 5 times, still it hasnt acheived it s peak tiem( as said in leflet), Ihave done all the battery tweaks, i dotn use bluetooth at all, and my wifi is on all the time, i have disabled receive beams, what else should i try? if anybody can help it will be useful, the phoen is wonderful but problems with battery, even with extended battery it is the same story.

Am i making any mistake? if anybody can correct me, it will be gret help
thanks
