LG G Flex: Battery Life

The LG G Flex has a giant 3,500mAh battery. It’s in the same ballpark as other 6-inch phones, but does beat most of them. The Sony Xperia Z Ultra has a 3,050mAh battery, the Samsung Galaxy Mega 6.3 a 3,200mAh battery and the HTC One Max a 3,300mAh battery.

As you would hope, battery life is strong. The LG G Flex will last for a full two days with moderate use. Battery retention when in standby is excellent, too. Left for a couple of days on its own, it’ll only lose a few per cent of its power.

We also tested the G Flex’s multimedia abilities as it’s an obvious phone to use as a portable video player. The phone stormed it with over 16.5 hours of video playback of an SD-quality DivX file at 50 per cent screen brightness. Its screen may not be perfect, but as a video player the G Flex’s stamina is hard to beat.

Giving life back to a fully-flat G Flex is also quick. It uses a fast charging to inject the initial 25 per cent of battery, for a quick and handy juice-up.

LG G Flex: Call Quality

One final claim LG makes about the G Flex’s curve is that it can improve your calls as it bends the microphone and speaker closer to your mouth and ear. While it’s true, it’ll only be of use in noisy conditions where you’d normally need to squish your flat phone against your face to hear the person on the other end.

Otherwise, call quality is of the solid standard we expect from a top-end phone. There’s a secondary microphone up top that provides noise cancellation for calls, and sound quality is respectable.

LG G Flex 9

Other things to consider

The LG G Flex is, as you’d hope given the price, a 4G phone. Although it is at risk of being categorised as a gimmicky phone, it hardly loses out on any mainstream tech doodads as a result.

Should I buy the LG G Flex?

So many of the phones we review are exercises in dull, rote iteration that it feels a shame not to be able to give the LG G Flex a commendation. However, its screen issues, high price and interface issues mean we can’t.

It isn’t harder to use than any other 6-inch phone, but such a large body is problematic too. The LG G2 costs half the price, and is in several respects the superior phone.

LG deserves a pat on the back for having the stones to bring as unusual phone as this to market. But seriously consider the HTC One or the LG G2 unless having a huge, curvy screen is really what your heart wants most.

Verdict

As an experiment with new technologies, the LG G Flex is a bold success. However, as a phone that LG wants us to spend £500-650 on, it has too many issues to be considered a contender for most buyers.

It's all well and good having a curved screen, but not if we have to go back to plastic screen coverings like the ones we used to have with the old resistive technology. It took ages to move to glass, and then a good glass that won't scratch easily. Plastic scratches far too easily, so unless we're going to see Gorilla making curved glass to fit these soon (thus removing all the flexibility you like) I know I won't be having one.

"the world's first curved battery" - I know what you mean, but I think I'd describe a regular AA battery as curved given that it's a cylinder. However, Apple may have something to say about this claim also as they patented the curved battery back in the summer... http://www.trustedreviews.com/...

Is a curved screen what people really want?

From the specs alone, it would seem that this is of inferior quality to current glass based screens.

What I would really like is for manufacturers is to focus on practical things liks a battery that lasts a week and takes minutes to fully charge or a phone that is robust enough for daily use but doesn't need screen protectors and bulky cases.

I suggest you actually read the article before posting comments like this. If you look at page 3, you'll clearly see that it does have Gorilla Glass. Corning have already made Gorilla Glass flexible enough to work on this phone.

I bent one in the shop today and it made a terrifying creaking sound, it seemed like it was breaking. Seemed quite pointless

you obviously didn't read the full article, as they state quite clearly that the phone DOES use Gorilla Glass, and it IS flexible. Make sure of your facts before you write smack dolt...

Just bought two LG G Flex phones. One of the units has a defective front facing camera that causes the error "Cannot connect to camera" to be thrown when selecting camera switch icon. The only way to recover the rear camera function is to Factory Reset. (tried all other options force stop camera app, restart unit,...). Even after Factory Reset front camera does not work and throws error (requiring Factory Reset again).

Iv had my G Flex since the end of this last summer 2014 and I absolutely love the thing!!! I have always personally favored and leaned toward the brand LG my reasoning being that of I have absolutely NEVER had any sort of kind of ANYsuch issue, no kind of problem absolutly nothing has ever occured with anything I have owned or even used of the brand LG! I have had accidentally drops or have had it slipped out of my hands or off a piece of furniture, it has landed on the screen on various surfaces such as pavement, cement, gravel (large & small & pee sized), sand, grass, carpet ect! I have yet had a scratch appear on my screen thank the lord, I try to keep it as safe as I possibly can so that nothing to horrendous does come about and happen cause forking out a hefty $200 or so deposit is insane, and not being guaranteed a brand new phone even having to pay that much is just flat out insanely ridiculous! If you pay for coverage and still have to pay a deductible of $200 you should absolutly be guaranteed a new phone not a phone that has been refurbished, cause no sooner than not there is going to be issues if not already have one two or 150! But yes my G Flex has absolutely been amazing I have had NO issues or problems my bettery has worked and still works amazingly and last depending how much I use my phone but can last up to 1.5-2 days, the shortest amount of time has been about 3-4 hours because of me using it non stop!
I hope people who have gotten it or that are thinking about getting it enjoy it and at least give it a.try cause it is a lot of fun and does wonders!! The video is absolutwly awesome as well I watch shows movies and recordings all the time and pictures are even more fun ont his thing I am in love with the thing!!! I wouldnt mind trying out the
LG G3 for my next phone or if somethng else cokes out along this line I would defintly not hold back!!!
