New iPad Notes: Battery Charging at 100%, Safari Scaling Images

Regarding the battery charging:

1) was the test done after the battery was "reset" by letting it become completed depleted?

2) If so, is the battery actually still charging even though it says "charged" or has auto shutdown not kicked in?

Regarding Safari:

I'm guessing sites see the browser is Safari Mobile. There should be an easier way to allow users to switch to "full Safari" but I'm guessing they don't b/c a full sites often use a lot of Flash which would then give a "bad user experience," we know how Apple feels about that.

Has anyone tried to see how the paid version of Atomic browser on "full" handles high rez graphics?
 
this is a huge complaint of even the other 2 iPads. Safari is crap with image resolution.

my parents read this site http://www.mingpaony.com/htm/News/20120322/bpage.htm# every morning, and it's just so blurry on Safari iPad when you select any of the pages.. The workaround is to use Firefox for iOS and select the option to display high resolution images.

apple, doesn't care about chinese newspapers.
 
Classy Reporting Macrumors...LOL



UPDATE: As of iOS 5.1, it appears there is an issue with high-resolution JPG images being presented in this manner. WebKit on Retina iPads will downscale the image and then upscale it again, leading to a significantly uglier image. The only known workaround is to use PNG images instead of JPGs (which obviously sucks for high-resolution images, which consume significantly more bandwidth than JPGs). Apple has been made aware of this issue: rdar://problem/11097671. If your image contains greater than 2 * 1024 * 1024 (2097152) pixels when you multiply the width and height together, you must use PNGs, or the image will not appear crisp on the Retina display.

Does this mean that Apple is admitting that "retina" display on tablets is pointless? Are they trying to mislead the public about charging time by falsifying charge indicator? Remember they did the same with signal strength indicator for antenna-gate version of iPhone.

did you read the post above you or are you just blabbering
 
The iPad Safari browser has always scaled down images. This isn't new.

As of iOS 5.0 you still have to specify the dimensions of a background image in CSS (-webkit-background-size) if it's over 2 megapixels, otherwise it gets resized down -- messing up your site's design. Apple's official documentation also noted that there was a limit of 3 megapixels in iOS Safari (tho maybe this has changed with the new iPad?).
 
Interesting about the image scaling. It doesn't help at all with the speed of the download since the whole image needs to be downloaded anyways. I guess the idea is to keep Safari's memory footprint low by downloading, downsampling, then getting the original image out of memory.

It's a safe bet this behavior will be tweaked for new iPads soon.

It only scales down JPGS, not PNGS
 
It is very clear that the battery issue should be investigated by the government and be made a big issue.

Why aren't the media especially NY Times and Consumer report not looking into this?

A consumer has the right to trust that when a device says 100% charged that it no longer draws additional electricity = cost behind the consumers back and without a consumers agreement.

We need a system preference panel pop up saying:

Battery almost full, but keep charging?
YES NO

Where is Senator Franken when we really need him?

You are assuming that Apple did not do this deliberately. This is very unlikely. Do you really think that they just slapped new LCD panel on iPad 2 without any testing?

What's the reason for the large images being scaled down? iOS bug?

because web sites should be optimised, which includes code and images - this is a good thing. If each image on a page is 2 - 3 meg, then how quickly would you use up your data allowance (let alone how long the images would take to load on your device when browsing).

The web should be optimised, fast loading and not data hungry. If you want to provide hi resolution versions of your images for download/offline viewing then that's up to the site developer, but for display on a 10" screen images at the standard 72dpi, when scaled down are perfectly acceptable, as well as sensible.

Not true. PNGs as background images also get scaled down when over 2meg - you need to specify background image dimensions in your css.
 
The way it continues to charge after reaching 100% is normal for any brandnew device based on Li-Ion or Li-Po cells. The charge controller needs to get its bearings on exactly how much capacity it can stuff into each cell and the cell capacity tends to increase it bit over the first few cycles anyway.

It's constantly counting how much energy goes in and out and after a few cycles I would expect it to be much more accurate.

No, they didn't -that's utter nonsense. They just changed the algorithm for the "bars" display so it was less accurate, like all other phones on the market.

You do more with an iPad than browsing the web, so saying the retina display is 'pointless' is utter BS - how many websites out there have retina graphics? That's a VERY long way off.
 
Hmm

Liking my iPad 2 for the moment. With a Mac Pro 12-Core, a 15" MacBook Pro, and iPhone 4S, I don't think the new iPad is justifiable for me. This seems even more so as wrinkles need to be ironed out. For those without an iPad, why not?

I would love to have Apple produce new high-res retina displayS for desktop's such as their Mini and Pro systems instead of one stripped down 27" iMac LED LCD panel. I can't even use the Thunderbolt display on my current gen Mac Pro w/ my ATI Radeon 5770. Guess it's all 'bout iDevices these days.

The Safari scaling issue is infuriating when looking for wallpapers. You simply can't look for them in your iPad because they're compressed to hell and scaled down to 1024x1024, you have to look for them on a computer, then transfer them to your iPad. I hope they fix this.

If you download them to photos on your iPad, they are displayed in full resolution. I had more difficulty saving them on my MBP and transferring them to the iPad than I did just saving images straight from the websites on the iPad.

Hi all,

I remember having trouble reading an online comic because some strips were bigger than 2Mega Pixels, the image was unsharp, as if the number of pixels was reduced to 1/4th (was confirmed on the ios Safari specifications doc)

is'nt it the same kind of behaviour ?

update: https://developer.apple.com/library/safari/#documentation/appleapplications/reference/safariwebcontent/CreatingContentforSafarioniPhone/CreatingContentforSafarioniPhone.html

Excellent post, that link should really be added to the article as it explains exactly why and under what circumstances this is done.

They could simply disable Flash plugin (which could be enable again through a jailbreak app :p).

As for the battery I haven't seen the issue yet. Mine says done charging at 100%. Maybe an unlucky few?

Did you have a ammeter or watt meter attached at the time? Because that's really the only way you'd know if it were still charging or not.

FYI on the image scaling - the article cited in the OP does not specify whether WiFi was used, so that's a source of some confusion. Do note that cell providers can and do downsize images.

Somewhere I have a document from Verizon from when I bought an LTE MiFi about a year ago that goes into detail on what they will do WRT downsizing.

Yes, I see iOS is likely the "culprit" here but there will be times operators downsize graphics.

This isn't about Background images this is about Safari !

Nope. They had to change the algorithm because it was proven that the original one lied about the signal strength.
