What Batterygate? The new iPad lasts 25+ hours when hotspotting



When used as a personal hotspot only over Verizon’s 4G cellular connection, the new iPad gets more than 25 hours of run time, AnandTech found out in their battery life testing published this morning. This is better than your average MiFi device by at least a factor of five. Matter of fact, it gets exactly an hour less in hotspotting tests compared to WiFi benchmarks, which falls in line with Apple’sofficial specs.
The Asus Eee Pad Transformer Prime beats Apple’s third-generation tablet when hotspotting in Normal, Balanced and Power Saving profiles. With that in mind, the ability to use your iPad as a personal Verizon hotspot for more than 25 hours is certainly welcome news in a string of negative reports alleging issues with the tablet’s much-improved 42.5Wh battery.

If you have an iPad on Verizon’s LTE network and use it as a personal hotspot (not currently possible on the AT&T version), it will last you roughly 25.3 hours on a single charge. Obviously that’s with the display turned off, but with a 42.5Wh battery driving Qualcomm’s MDM9600you get tons of life out of the new iPad as a personal hotspot.
If you’re one of the fans concerned about the iPad’s battery woes and appreciate AnandTech’s exhaustive technical reviews, you should also check out theiranalysis of the Retina Display on the new iPad.
As for Heatgate and the emerging Batterygate, let it be known that not everyone agrees with screaming headlines depicting the device running burning hot in one’s hands.

Sure, it gets warmer when you crank up the brightness level to 100 percent, but people are finding in their own tests that it runs cooler than some Android tablets (as always, not everyone agrees).

If  you’re really eager to get to the bottom of this overcharging thing, I suggest a nice article by MacWorld UK that lays out everything you need to know about charging your iOS devices. Apple also has nice resources on the subject on theirwebsite.
It is my hope that we all can soon put this so-called scandal behind us and move on. Call me a conspiracy theorist, but I definitely get this feeling that ever since the so-called Antennagate scandal erupted – and it was an issue, no question about it – bloodthirsty media is adamant to make teething problems with new Apple products look bigger than they really are.
Jonathan Mann put it best in the iPhone Antenna Song:
The media loves a failure
In a string of success
The facts won’t ever matter
If they can make bigger messes.
I think that pretty much nails it, wouldn’t you agree?

That entry-level data plan you signed up for to go along your brand spanking new iPad? It’s obsolete, thanks to the device’s 4G LTE networking that allows for speeds easily exceeding your home broadband connection. As a result, folks planning on enjoying 4G speeds on the go may likely blow past through their monthly allowance in a couple days. Your mileage may wary, of course, depending on your mobile usage habits.
Here in the U.S., entry-level data plans for iPad begin at ₨764.17 or ₨1,528.35 a month,depending on your carrier. AT&T’s entry-level 250MB plan will set you back ₨763.66 a month, with 2GB/5GB plans costing ₨1,528.35/₨2,547.24 a month. Rival Verizon Wireless is offering 2GB/5GB/10GB tiers priced at ₨1,528.35/₨2,547.24/₨4,075.59 a month.
But even five gigabytes a month is conceivable insufficient when you stream high-definition movies and television shows to your device over 4G LTE networks, upload big photos to your social networks or edit and upload full HD movies to YouTube, etc. The Wall Street Journal has the full story (subscription required)…
According to the publication, once customer was able to burn through his 2GB cap just by way of wirelessly streaming March Madness games during a two-day period.
Two hours of college basketball—which he viewed mounted to his car dashboard and live at tournament games—had burned through his monthly wireless data allotment of two gigabytes.
This hardly comes as a surprise given 4G LTE download speeds are anywhere between 10-20 times greater than a typical 3G HSPA+ connection enjoyed on your iPhone. It could be argued that neither Apple nor carriers are doing much to educate average consumers of the intricacies behind cellular data management.
Another layer to this problem is the Retina display that packs a million more pixels than an HDTV. Coupled with fast 4G LTE data speeds, this means users are likely to stream 1080p video to their iPads, increasing their data usage.
And we all know your carrier will happily impose a surcharge for data traffic outside your monthly data cap. The Journal explains:
Verizon estimates that streaming it over an LTE connection runs through 650 megabytes an hour. That’s double the amount of data used streaming the same video over a 3G link, because the fatter pipe lets more data through. On top of that, the new iPad’s sharper screen will encourage some users to view videos in high-definition, which uses 2 gigabytes an hour on a 4G connection, according to Verizon.
The report has it that Apple and carriers could partly mitigate the issue by having developers pay for data their apps consume on cellular networks as this traffic wouldn’t count against the user’s allowance. Until some sort of an industry-wide agreement is reached, users are left to figure out their cellular data consumption on their own.
Unfortunately, the most recent version of iOS is lacking basic controls to manage data consumption on the go. Wouldn’t it be nice if iOS gained finely-tuned data management akin to Android Ice Cream Sandwich, allowing people to set warning limits, per-app data quota and more?
