LG G2 KitKat benchmarks

After the LG G2 received its KitKat update we decided to see what’s what and check out if the phone’s performance has seen drastic changes compared to its Jelly Bean state. We re-tested the battery performance and now it’s time to put the chipset through its paces.

The battery performance showed a leap from a 62 hour endurance rating to an 81 hour one, which was mainly due to a much-improved stand by time. As for the benchmarks, well, there’s a different story here. Note that KitKat brings faster multitasking because of optimized memory usage, which should aid in better benchmarking scores.
The LG G2 offers a very capable Snapdragon 800 rig with a quad-core 2.26 GHz Krait CPU, 2 GB of RAM and the Adreno 330. This is still considered flagship material hardware even with Snapdragon 801 and its faster GPU lurking about.


Let’s see in the tests below. BenchmarkPi and Linpack are both centered around the CPU performance – the first looking for single core and the second for multi-core performance. Both show a lead for the Jelly Bean LG G2 but the difference is more notable in Linpack.

Benchmark Pi

Lower is better
  • LG G2 (Jelly Bean) 99
  • LG G2 (KitKat) 158

Linpack

Higher is better
  • LG G2 (Jelly Bean) 1054
  • LG G2 (KitKat) 749
GeekBench 3, AnTuTu 4 and Quadrant test everything about the hardware setup – from CPU to graphics, to read/write performance. The results are are mixed bag – the KitKat G2 prevails in Geekbench 3 but fails to beat the Jelly Bean G2 in either AnTuTu 4 and Quadrant.The difference in Geekbench 3 and Quadrant is dismissible but AnTuTu 4 shows a score difference of 5516 points in favor of the Jelly Bean G2.

GeekBench 3

Higher is better
  • LG G2 (KitKat) 2403
  • LG G2 (Jelly Bean) 2243

AnTuTu 4

Higher is better
  • LG G2 (Jelly Bean) 35444
  • LG G2 (KitKat) 29928

Quadrant

Higher is better
  • LG G2 (Jelly Bean) 19815
  • LG G2 (KitKat) 19160
Moving along into GPU territory it shows almost identical scores for both software versions of the device that could have easily gone either way. The KitKat G2 takes the 1080p offscreen T-Rex test (by 0.2 fps) and loses in the 1080p offscreen Manhattan test (by just 0.1 fps). The only big difference is at the on-screen and Epic Citadel, where on KitKat the G2 managed 6.3 fps more, suggesting that LG might have found a way to squeeze some more power of of the GPU.

GFX 2.7 T-Rex (1080p offscreen)

Higher is better
  • LG G2 (KitKat) 22.4
  • LG G2 (Jelly Bean) 22.2

GFX 3.0 Manhattan (1080p offscreen)

Higher is better
  • LG G2 (Jelly Bean) 8.6
  • LG G2 (KitKat) 8.5

Epic Citadel

Higher is better
  • LG G2 (KitKat) 57.7
  • LG G2 (Jelly Bean) 51.4
Now that we’re getting to the final part of our benchmarking comparison – JavaScript and HTML 5 performance. Here KitKat should make a bigger impact – each new Android version boasts better browsing and faster web performance.
And indeed the KitKat-kitted LG G2 manages a much better score in the JavaScript-centric SunSpider and still outdoes the Jelly Bean G2 in HTML 5-focused BrowserMark 2.

SunSpider 1.0.2

Lower is better
  • LG G2 (KitKat) 549
  • LG G2 (Jelly Bean) 902

BrowserMark 2

Higher is better
  • LG G2 (KitKat) 2885
  • LG G2 (Jelly Bean) 2718
So it appears LG has done some software trickery on the Jelly Bean build of the LG G2 but didn’t bother as much on the KitKat build. That’s just a theory though – we’re not calling LG a cheater just yet. The significant differences in Linpack and AnTuTu 4 in favor of the Jelly Bean version do seem suspicious, but even if cheating was the case it’s good that LG has given up on it now.
As always we urge you to look not only at benchmarks but into the real-life performance of a device. Scores are meaningful at times but looking at the G2 with KitKat and Jelly Bean will reveal that nothing has changed dramatically. That’s not to say KitKat isn’t an improvement on speed – just that the LG G2 was a perfectly capable smartphone to begin with.

Attopedia puts Wikipedia on your Android Wear smartwatch

Image
If the recently gone native Wikipedia mobile app seems to much of a hassle for you, meet Attopedia – the first Android Wear app to put Wikipedia on a smartwatch. The app is free and features an interesting UI paradigm in line with Android Wear’s gesture based control. Once you’ve selected an article, swiping up or down selects an article section, while a left or right swipe explores the content of the section. The project looks like it could be really useful, but we’re sure most of you would prefer to get the phone out of your pocket and browse it on a bit larger display. Nevertheless, this could be an ideal solution for a light reading if reaching for your phone isn’t an option. Packing an Android Wear smartwatch? Great, now head over to the source link below and get Wikipedia on your wrist.

D.M.A. Navi Watch app for Galaxy Gear puts Google Maps navigation on your wrist

Image
You own a Galaxy Gear and need to get somewhere but don’t know the way. While Google Maps integrates with Android Wear, your Tizen-powered Samsung Gear smartwatch can’t use Android Wear apps. How to get out of this conundrum? The free D.M.A. Navi Watch app. The app still uses Google Maps for navigation, but transfers the notifications put out by Maps onto your wrist. To do this it will need access to read your notifications. Here’s a video that shows how that’s done plus the rest of the setup process to get D.M.A. Navi Watch up and running. And here’s a video of the app in action: The app is available for free from the Samsung Gear app store. People have reported successfully running it on both the original Galaxy Gear and the Gear 2.

iPhone SE teardown shows hardware ranging from iPhone 5 to 6s

Image
The Apple iPhone SE is a 6s in a 5s body, but Chipworks dug into the internals and it turns out the story is more complicated than that. It straddles multiple generations - from the iPhone 5 selfie camera to the iPhone 6s chipset, a whopping four generations. The Apple A9 chipset is brand new and the SK Hynix-made LPDDR4 2GB memory matches the 6s as well. The NFC, audio chips and motion sensor are from that generation as well. The storage appears to be from the 6s as well, but an earlier 19nm chip instead of the 15nm being shipped now. The Qualcomm modem from the earlier iPhone 6 model while the touchscreen controller goes back to the iPhone 5s. Using the images and info from Chipworks, I labeled the parts on the motherboard with the iPhone generation they come from. Source | Via

OnePlus 2 torn down, gets 7/10 for repairability

It’s not the first time we’ve seen the OnePlus 2 disassembled, but since we haven’t practised our Chinese this lifetime, we have to admit we struggled a bit with the translation on the previous occasion. It’s nice then that iFixit got round to tearing down the self-proclaimed “2016 Flagship Killer” so we can gather up some more easily digestible info. The procedure kicks off with an X-ray shot of the smartphone, but regardless of its outcome, the device was already scheduled for surgery. Removal of the back cover is simple and the non-proprietary screw heads to reveal the innards are a nice touch. The folks then proceed to remove the non-removable battery and dismantle the camera modules, pointing out that the 1.3 micron pixel size of the 13MP sensor is the largest they’ve seen. The mainboard is held by a single screw, while the microUSB Type-C connector/cable assembly should be easily replaceable. Of course, the various chips are detailed, but the bottom line is

Can a Chromebook Replace Your Laptop?

Image
For years, my daily computer was a commendably-powered and somewhat pricey Asus gaming laptop, but after natural wear and tear began to set in, it became obvious that my machine was slowly but surely breaking down—performance was becoming more and more sluggish, the battery's capacity was dropping, and I even had to have its charging port repaired at one point. But as clear as my trusty Asus' inevitable demise was, I didn't have the funds to replace it with a new Windows-powered machine, so instead of continuing to use an unreliable computer for work, I was given a Chromebook Pixel to try out. The idea had me feeling somewhat uneasy. CES was quickly approaching and the thought of tackling one of the year's biggest tech events using a glorified Chrome browser didn't exactly seem like the best plan. But I was just as curious as I was cautious. Could a Chromebook really replace my traditional laptop? Fortunately, I survived CES using the Pixel a
