Nokia Lumia 635 Review

Call Quality

Impressively, call quality is a vast improvement over the Lumia 630. Clean and crisp toned voices!

Who knows if it’s an actual improvement to the hardware, or merely the result of our good coverage with T-Mobile’s network in our area, but the Lumia 635’s call quality is outstanding. Not only are voices clean and crisp on both ends of the line, but the high pitched volumes of its earpiece and speakerphone help to overcome some of the distractions in noisy environments.


The battery capacity isn’t particularly massive, but it delivers longer juice than what you’d expect.

The Nokia Lumia 635 climbs to near the top of the charts with its astounding battery life, as its 1850 mAh battery pulls in over 9 hours in our battery benchmark test. It’s not a record, but it’s nonetheless more long-lasting than other handsets with bigger batteries. In our experience, we’re able to get close to 2 days of normal usage from a full charge.

We measure battery life by running a custom web-script, designed to replicate the power consumption of typical real-life usage. All devices that go through the test have their displays set at 200-nit brightness.

Making a phone overseas is one thing, but making one for the US is totally another. So, how did Nokia improve upon the Nokia Lumia 630? Well, they’ve outfitted the Lumia 635, a subtle variant of the aforementioned phone, with good ‘ol 4G LTE connectivity. At the same time, the Windows Phone 8.1 powered device sees improvements to its call quality to really deepen its worth for the budget-conscious consumer.Lumia 635 is attached with an amazing price point that makes it a bargain however way we dissect it. Specifically, T-Mobile is selling the phone for $0 down and $7 per month for 24 months through its Simple Choice Plan – giving it a total price point of $168. Furthermore, the handset is being offered at the promotional price of $99 through MetroPCS. Frankly, the price point alone is an aggressive one that undoubtedly adds more value to its package.

However, it's not without competition. Motorola Moto G is its biggest rival. The Moto G runs on the richer in terms of apps Android 4.4 KitKat operating system, and has a sharper 4.5” 720p HD display, slightly better camera, and is similarly well-packed in terms of specs. An even cheaper option is the Moto E, a phone with just a slightly smaller, 4.3” display, but also with good performance, offering great value for the money.

Software version of the review unit: Windows Phone 8.1


  • Aggressive, low pricing that makes it a bargain
  • New Windows Phone 8.1 features enhances the experience
  • Battery life is surprisingly long-lasting
  • Excellent call quality


  • Camera is mediocre
  • Performance hitches with gaming
  • Low resolution screen shows visible pixilation

I love this phone it has the most unique personalization for a wp because u can buy individual like if you got the black one and wanted the green one. Nokia sells the back plates off of their website

It is more than enough to power WP8.1. Stop it with this "low RAM'' BS.

Its not enough to run heavy games smooth so need at least 1gb ram

There is very few games that cannot run on 512mb of ram off windows. Mainly because of the OS is that efficient. Unlike my s5 friends, who have had it less than a month, and with few downloads, their ram usage is at 1.3gb with 300mb ftw.

Can't run the new lock screen app from WP. Stop this bs, it doesn't need specs to run. Half baked hardware.

Excellent review and video review. I'd like to pick up one for ATT to give to someone so that they can try Windows Phone. $99 (no contract) for the 635 is an amazing deal for LTE, Cortana, MixRadio, Here Drive+ and all of the Windows synchronization that comes with Windows Phone 8.1. The Lumia 630 offers a lot of value for such a low cost device.

Mmm ya PhoneArena is strange with their reviews. I just went back to WP, Snagged an awesome deal! on the Samsung ATIV S Neo AT&T model running perfect on Cricket Wireless & it is a way better device then this. Yet you rated it only a 6.5! And stranger yet the ATIV S (esentially the same phone is rated and 8). I know its not all about specs. But the Ativ has an awesome clear hd screen, great camera etc. I also think that some of the reviews I have read on it were worse because they were testing the Sprint model. Which would attribute to the slowdowns in the reviews. This 635 ya has wp 8.1 with Cortana on it already. But what else about it merits a higher score over the Ativ S Neo.

512mb of RAM? That's unacceptable

Phone can't even run the new lock screen app by MS themselves.

Lumia 625 vs 635 625: Front facing camera, camera flash, overall better design, better battery 635: Clear black display, newer CPU Conclusion: Lumia 635 is two steps forward, but 4 steps back. :(

You just compared a flagship phone to an older mid-range phone. Your opinion no longer means anything.

Youre totally right, I had Lumia 820 and compared to Galaxy S4, the Nokia Lumia 820 was way so much smoother.
