Windows Phone 7.8 is not faster than WP7.5

The often-forgotten (even by Microsoft) update to legacy Windows Phone devices, Windows Phone 7.8, has faced its fair share of delays and issues, but now that it's readily available for a number of devices 7Tutorials managed to take a look at how it performs. Using a Nokia Lumia 800 both before Windows Phone 7.8 was installed, and after the most recent live-tile fix was applied, the site ran a number of tests to determine whether the updates were only cosmetic.

Unsurprisingly, the site concluded that Microsoft hasn't included any performance improvements, simply focusing on porting a few basic features from Windows Phone 8. In the benchmarks there were no meaningful differences in the speed between WP7.5 and WP7.8, with most results from synthetic benchmarks, browser benchmarks and boot times falling within 2% of each other.

It's quite possible that Microsoft explored performance enhancements for Windows Phone 7.8, however the slow single-core Qualcomm processors coupled with 512 MB of RAM used in legacy devices leave little room for speed improvements. The operating system is still very smooth to use despite the lack of any notable differences from the last major update, and it's looking likely that we won't be seeing any further software updates for these devices.

I've force the 7.8 update for a couple of friends. I asked them about any performance difference and they all said they noticed none. They haven't expressed any issue though.

7.8 is faster in many ways that actually count, Android 'benchmarkers' just don't get that side of the equasion. Obviously the hardware hasn't changed nor the kernel so pure performance would be anomalous anyway.

The smaller tiles alone means nav is easier and quicker, ie faster.

Well, I was going to complain about the lack of "news" in this. Until I saw that it was authored by Tim Schiesser. Now, I completely understand why it lacks newsworthiness.

honestly, I haven't even been able to receive the update- and i'm starting to be glad that I can switch directly to WP8

Since upgrading to 7.8, my phone signal has been very intermittent.

I never had any issues with 7.5 in my town, Since 7.8 I rarely have signal at home or at work. Though if I reboot it, I suddenly get three to 5 bars.

Given my phone is meant to switch between Orange and T-Mobile, if signal is lost, this is annoying.

Contemplating going back to 7.5 to see if this fixes the issue, or whether my phone operator signal suddenly just sucks in my area nowadays.

Don't really want a new phone at the moment.

I thought it was a well established fact that Windows Phone 7.8 is pretty much nothing more than Windows Phone 7.5 with the new Start screen slapped on.

Well, I have noticed that some native apps like Marketplace, Calendra, XBoX live launch slower (a few milliseconds when nothing happens after you tap the tile) before the animation kicks in

I wouldn't have expected it to be faster on older devices anyways. If anything, I'd think it'd be slower.
It's the cosmetic changes and features people want from the upgrade.
Well the people who want their old Windows Phone to look like Windows Phone 8 anyways.

Btw theres a mistake on the home page blurb; "Windows Phone 7.8 is not any faster than Windows Phone 7.8 on legacy devices"

Good article though

I notice the performance issue after upgrading to 7.8. But am already fall in love with the new home screen, would never return to 7.5 for performance.

What performance issue? 7.8 is not slower than 7.5, they are the same.

I've noticed quite a difference in time between tapping an app tile and the app opening, compared to what it was on 7.5. Music+videos will sometimes wait a few seconds before opening, whereas before it opened almost instantly.
