LG Optimus L9 Review

Callers were very impressed with the Optimus L9, rating us 8.5/10 and calling it one of the more clear phones we’ve tested. They said there was a slight hollowness to it, but voices were clear and they had no problems hearing us. They sounded great on our end as well, with plenty of volume and natural voice reproduction. Even with a noisy background we didn’t have any problems hearing our caller. LG claims “usage” time of 1 day and 5 hours on the 2150mAh battery. While that seems a bit vague, in our testing we had no problems getting through a typical day with plenty of battery left.


The LG Optimus L9 brings a great budget option to T-Mobile’s lineup. It is of course not as good as the forthcoming Nexus 4, but it absolutely holds its own with similar offerings from HTC and Samsung. The 4.5” IPS display is wonderful, and the dual core TI OMAP processor delivered smooth performance. We would have preferred a better camera, but at $80 on contract we can’t complain too much. Call performance and battery life both exceeded expectations, and we are a fan of the Optimus L9’s sleek design as well. T-Mobile certainly offers better devices, but for the price you’re not sacrificing much with the Optimus L9.

Android 4.0.4
Software P76910e

I don't see why those cons eat 2.5 of total score. it's a mid range phone did someone forget? I think it deserves at least 8. snappy performance alone could warrant that.

And why no Gorilla Glass if L7 has?

The international version has gorilla glass 2 not so sure about the T-mobile version but i suspect the only difference is the 0.2" of screen real estate between the 2

This site seems to rate the camera quality on some good phones as a negative alot. Whereas phonescoop etc said this phone takes great pictures. Which it does! Wow I think it takes some of the clearest shots ive had. Its better then the 8mp on Lumia 822 I was using. So just goes to show mp count doesn't mean everything. Is Phonearena not focusing right or what...? lol. Anyway I thought I was fully converted to WP8 but im loving Android again with this device. Especially on Tmobiles no contract plan. This phone is awesome for 199!

This is an awesome phone and since it is no-contract, it was easy to use on Solavei where my cell service is now free. Compared to my previous ATT bill, that's over $1,200 in annual savings. Yeaaaah!

LG has been known for not supporting their software upgrade. You may get the latest android right now. But you are going to stuck with that android version for the rest of your smartphone life. Don't buy LG, you will regard it next year when everyone is using Android 5.0. I am a victom of the G2X, they promised to upgrade it when it was released 2 years ago. I now have a samsung s3 and the g2x still hasn't get that updated LG originally promised. In fact, LG don't even response to G2X update questions at all... LOL

I hear ya but im not super worried abt the software update. As long as it's nothing major im missing. If I keep this device for at least a year that will be good for me as I have been going through phones to fast. I haven't liked other things abt some lg's in the past but overall this one is good, & has overall good marks.

It's uncanny that the international L9 specs are very similar to the Galaxy Nexus... I wonder how that came about...

I'd like to point out that the panorama function seems to use the camera mode, rather than the photograph mode, which results in panorama pictures having very small vertical resolution.

We have included a sample in our review at Teknofilo.com blog and, while the article is in Spanish, you'll easily spot where the panorama picture is.
