This is a post by Surface Pro 2 owner Hector Gomez who shares his battery life report after one month of usage…
When Microsoft announced the first Surface Pro it got hit with many reviewers claiming battery life was only around 3.5 hours. I personally got a good 5 hours, and yes, if I watched a lot of videos on it, it did drop down. Though I was able to get a full work day use out of it I accepted I would always have to carry the power supply with me for full-days of usage. That changed with the Microsoft Surface Pro 2…
It is possible to feel confident that you’ll last the day without your charger. I experienced it for the first time with Haswell and with the Fujitsu S904 it’s possible you could even do a two-day + hotel stretch without a charger. It’s not an Ultrabook because of the battery bump but at only 1.5KG it’s probably got the biggest battery / weight ratio of any laptop or Ultrabook.
Testing power usage on Haswell Ultrabooks is difficult due to the huge range of scenarios that the next generation Ultrabooks have. They’ll stream music for days and yet if you try to do too much gaming on them, you might be out of juice in as little as two hours. What we can say though, without a shadow of a doubt, is that the battery life on Haswell Ultrabooks, compared to Ivy Bridge Ultrabooks is hugely improved. We’ve got a Dell XPS 12 with Haswell here that proves it.
There isn’t a manufacturer out there what will tell you how long that sealed-in battery will last and you’ll be lucky to get any idea of replacement cost, or even possibility, before you buy that product.
I’ve got an Ultrabook here that is reporting a warning that the battery needs replacement after just 18 months. On another, that I’ve been using for well over a year, the wear level is just 14%. In this article you’ll find out why Ultrabooks have sealed batteries, how to check your battery health, tips for prolonging the life of your battery and some examples of Ultrabooks with removable batteries.
Sure, we can all get an Ultrabook to run for 10hrs. I did it myself recently when I put a Samsung through a typing test but how about being online and running web apps? Running the web through a browser is one of the most taxing things you can do to a laptop so seeing 9.5hrs runtime in a MobileMark2012 test is something worth checking out, in 60 seconds with a timelapse video. Haswell is doing the business.
What’s Connected Standby? It’s the hardware and software that turns a PC into a smart device. Always on, Always Connected! You can find more information here and I encourage you to read it and to consider this ‘seal of efficiency’ for your next laptop or mobile PC which, in 2013, can only be an Ultrabook or a Clovertrail or BayTrail based laptop, tablet, convertible or dockables.
Here’s a way to check for Connected Standby, battery capacity and to view historical battery life reports. Useful to use quickly in the PC store!
While Ultrabooks generally perform to similar efficiencies under load there’s quite a difference when it comes to near-idle operations and that can seriously impact the length of time you can use an Ultrabook as an offline word processor. As a blogger that’s a very important scenario for me and I suspect that if you’re offline and answering a bunch of emails or writing a presentation or report, this scenario is important to you too. If you choose the right Ultrabook you can get 10 hours of typing on one battery charge.
Sharp’s press conference has just finished at CES 2013 and within it was one of the important technologies of 2013 when it comes to mobile devices and power consumption. IGZO.
As CPU, GPU and comms power requirements fall, the screen becomes a very big, power-hungry issue. IGZO screen technology could really help extend in-use battery life and that’s why we’re watching it closely.
This ground-breaking integration of Windows 8 and PC hardware will change the way you use a PC and it’s likely to be an Ultrabook-exclusive for much of 2013 and 2014. Connected Standby is ‘on’ for Windows 8 apps when the PC is ‘off.’ It means you can run Windows 8 applications like Skype to provide voice and video services when your PC is in your bag, and much more.
There’s an Ultrabook battery report out from the Electronics TakeBack Coalition – a company that “promotes green design and responsible recycling in the electronics industry” and it doesn’t look too good. Only 2 Ultrabooks have been highlighted as having removable batteries but there’s a different side to this story that hasn’t been considered by the ETBC.
There have been a couple of Ultrabook battery-related news items in the last few months. Both, I believe, stem from what was talked about at Intel’s IDF event in Beijing. The first article highlighted how Intel introduced a standard size battery. The most recent article mentions the cylindrical 16650 type cell, a smaller version of the very common Li-Ion cell found in removable laptop battery packs. “Intel Hopes New Batteries Can Reduce Ultrabook Cost.” said the article title.
Most of what is going on is summarised in this slide.
