My phone doesnt last 3 days. 1day 15hours on a full charge [ Can see more about that here:

And it takes more than 2hrs to charge (well my fault for using USB-Laptop I believe)
Mine takes more than 2 hours to fully charge. It takes less than two hours of charging to get one days worth. If it was down to zero, it would take 5 hours to charge fully.
I saw your other thread but didn't even know where to start because it seemed to assume a lot of things that weren't necessarily true. Not saying anything you said wasn't right but based on all the facts, I would not have the same conclusions.
The biggest variable that may be overlooked is that the estimated battery life is not reliable. The phone relies on information from the battery other than just the current flowing from it to make the estimates. The battery itself could be misinforming the phone and I have the impression that is not unusual. I believe the phone's estimating programming tries to adjust for that based on past experience since the phone was last hard reset. So basically, a new phone is much more likely to give bad estimates than it will after it sees how well its estimates match reality. And everything I know about programming (I've written OSs) tells me the battery needs to be run WAY down to (a) see how reliable the battery's reporting is at all levels and (b) better compare its own estimates with reality. The more times, the better. If an owner's usage matches some developer's projection AND the battery and its own reporting matches the specs the more accurate estimates will be out of the box, but since the system is capable of self correcting estimates, there can get away with significant variations between individual parts.
The other question your thread raised was how typical was the usage in that very short time since full charge. Unless you are very unusual your phones actual battery usage varies quite a bit minute to minute between charges. Remaining estimates are based on past and current usage. So an estimate of remaining based on a very short time since the last charge may be way off particularly when there is little past history to factor in.
So my take was you MIGHT not have a problem but time will tell and if there was a problem it could be the battery rather than something harder to track down and repair, not that you will necessarily care what they had to fix.
