It seems like Apple made a judgement decision in its battery logic for this behavior- is there a technical reason Apple couldn't have had it read 100% when the battery was actually at 100%? (of course, fully support it staying at 100% when it is going through its discharge/charge cycle- I'm only concerned with that initial threshold for "100%")
I don't necessarily mean 'deception' in a negative sense- from the little I know, it seems to be a good, simple, solution for the consumer. Again, I fully admit I'm probably making the battery experts around here cringe
Very fair point. I can't see any explanation for this either. And this quote
That's by design, Apple's Michael Tchao said to All Things D on Tuesday. All iOS devices, including the new iPad, will display that they are 100 percent charged just before the device reaches a fully charged state. The device will then continue charging, then discharge a bit, and recharge once again a cycle that will continue until the device is unplugged.
Just doesn't explain anything.
And another issue here is, how "just before" this just before is. Could it be possible that on smaller batteries on other iOS devices this just before is a bit different compared to the enormous battery of the new iPad? If people are reporting an hour to real 100% on the new iPad, it could very well be that the extra ten percent on say an iPhone takes another 10 minutes, but on the iPad it takes an hour. I am quite sure from experience that the last % of charge are always the slowest.
Can somebody please get technical here, because apple's simple explanation, amounts to no explanation at all, because it raises the obvious question why not report it at 100% when it is actually 100% and then continue with the discharge and recharge cycle.
I have a suspicion on why they done this, here's my theory: Maybe they guesstimated that no one pulls the plug out exactly at 100%, quite possibly people look at 90% wait around a bit and take the plug out after a few minutes of the reported 100%, at which stage the battery WILL be at an actual 100% because quite possobly it won't be on a discharge cycle.
Even if this, largely unfounded, theory of mine is wrong, it seems they need to tweak the algorithm for the new iPads larger battery and they haven't done so yet, yet they are not admitting this. It would be very interesting if someone could report actual and reported battery charge for their new iPad now, and after an iOS update, I am sure it will be different.
