Battery Life
With everyone sharing the same base hardware and software there are only two items that will ultimately impact battery life between vendors: screen type and battery size. The pecking order is pretty easy to follow. Smaller LCDs will be the best on battery, larger Super AMOLED screens will be the worst. The battery scale is even easier to define: bigger is better, but heavier.
We’ve been testing three Windows Phones: HTC’s Surround, Samsung’s Focus and the LG Optimus 7. The HTC and LG use standard LCD displays, while the Focus uses the same type of Super AMOLED screen we saw in the Fascinate and Epic 4G.
The LG uses a 5.55Whr battery compared to 4.55Whr on the HTC Surround. As a result LG gets the best battery life out of the three with the Focus coming in last due to its Super AMOLED display.
Microsoft mandates three discrete display brightness settings on all phones: low, medium and high, coupled with an automatic brightness mode. The three phones delivered very different levels of brightnes at each setting:
| Brightness Comparison (White Point) | |||||
| Phone | Low | Medium | High | ||
| HTC Surround | 10.4 nits | 183.1 nits | 405.7 nits | ||
| LG Optimus 7 | 130.4 nits | 259.1 nits | 381.2 nits | ||
| Samsung Focus | 61.9 nits | 143.1 nits | 234.3 nits | ||
| Brightness Comparison (Black Point) | |||||
| Phone | Low | Medium | High | ||
| HTC Surround | 0.03 nits | 0.39 nits | 0.88 nits | ||
| LG Optimus 7 | 0.28 nits | 0.56 nits | 0.82 nits | ||
| Samsung Focus | 0 | 0 | 0 | ||
Overall battery life of these Windows Phones ranges from average to above average in the case of the LG Optimus 7. The use of Qualcomm’s 65nm SoC definitely doesn’t help battery life, but Microsoft appears to have done a reasonable job with power management.
The first Windows Phones won’t be in the same realm of battery life as the iPhone 4, but it’s a reasonable starting point. Given a normal/light workload you can easily make one of these things last a full day on a single charge, but heavier users will probably find themselves charging once in the early evening. As with most aspects of the platform, we need to see significant improvement in the next 6 months for Microsoft to be taken seriously. Luckily for Microsoft, where it is today isn’t a bad place to be.

I think WP7 has potential and could very well be my next purchase. Great article guys, it was long but very detailed.. got me through a boring afternoon.One thing seems missing though... the infamous signal strength comparison that you have been doing for all other phones ever since iPhone 4.

One of the most informative WP7 reviews I have read. I actually didn't skip to the end just to read the conclusions. I read it all and enjoyed every page. Well done.epyon96 - Thursday, October 21, 2010 - link
Did I read that right?Only Mp4 and WMVsupport?

I'm guessing that is the audio codecs allowed for videosTanclearas - Thursday, October 21, 2010 - link
"When Apple introduced the iPhone, Steve Jobs made the point that a virtual keyboard was preferable to a fixed keyboard because you shouldn’t always be stuck with the same keyboard layout. Some applications would require a slightly different layout and other applications wouldn’t need it entirely. A physical keyboard requires you to pay the space penalty regardless of what you’re doing with the phone."Really? So, by that argument, Google/Android is the better choice of phone. You shouldn't always be stuck with a single choice of phone layout. I use my hardware keyboard regularly on my G1. As for "applications requiring a slightly different layout", that's a load of crap. When typing, I always want letters and numbers, and I want QWERTY with number keys above. I don't want an on-screen QWERTY with a separate button to press to switch back-and-forth between letters and numbers.
The "applications that require a slightly different layout", perhaps like the phone keypad, can still use an on-screen keypad when necessary.

Windows 7 Phone must be absolutely phenomenal given the writers' incredible Mac-centric slant (especially with the Windows 7 desktop non-sequitor at the end of the review). Furthermore: The e-mail and messaging pages don't include comparisons to Blackberry, the de-facto standard for communication on smartphones. In fact, I cannot recall that line of phones being mentioned at all. As an existing Blackberry user considering a switch to Windows 7 Phone your review is nearly worthless, because 99% of my phone experience is about functionality and not whether or not my handset can sing and dance better or worse than iOS and Android.Normally I enjoy reading Anand for very thorough reviews, but this review's omission of the essential and inclusion of the irrelevant will make me reconsider reading any future submissions by these two writers.

C'mon man, although Blackberry is a mkt share leader, it is a 20th century platform with very little innovation. It is walking dead with respect to consumer devices, which is the segment that Windows Phone 7 is currently targeting. I own a blackberry for work, but there is no way in hell I would consider it for my personal mobile device, and I don't give a rat's ass that it is excluded from comparison.Reven - Thursday, October 21, 2010 - link
I'm happy with my iphone 4 for now, but I will seriously consider getting the next generation of Windows Mobile phones when I eventually upgrade.anona6 - Thursday, October 21, 2010 - link
Hey I live in Tucson, and I was wondering if anandtech was based out of Tucson or something.This article made it a little more exciting for me just because it was local to me, and you have
one of my favorite coffee shops there that's nearby my University.

Do you know what the talk time is for the LG? It's not showing on the graph
