LG Optimus 4X HD fails to impress in battery life test despite power-saving core and large battery

The LG Optimus 4X HD uses NVIDIA’s Tegra 3 chipset, featuring a special power-saving CPU core which NVIDIA made a lot of noise about. Couple that with a large 2150mAh battery and the Optimus 4X HD should be more than simply adequate in terms of battery life, right?

The HTC One X has similar specs (Tegra 3, 4.7″ 720p LCD), but a smaller battery (1800mAh), so it didn’t quite top our charts even with the above-mentioned extra core. Read on to find out if the LG will do.

Talking over 3G, you can drain the battery on the Optimus 4X HD in 7 hours and 41 minutes – not bad, but the One X lasted nearly 10 hours. Okay, to be fair, the wireless chips are more important for this test than the Tegra chipset alone, so let’s move on.

LCD-packing phones typically last longer in our web browsing test than AMOLEDs, but that big 4.7″ screen means more power gets drawn from the backlight. The results were pretty disappointing – the LG Optimus 4X HD called it quits a minute before hitting the 4 hour mark.

The One X didn’t do much better though – 4 hours and 18 minutes. However, the Krait-based One X for AT&T lasts a bit over 5 hours (all tests are over Wi-Fi), so it’s not just the screen that’s the limiting factor here.

The Optimus 4X gets one last chance to redeem itself in the video playback section of our test. But with a 4 hours and 14 minutes result it falls short – the HTC One X went on for an hour and a half more.

After going through the numbers, the final endurance rating for the LG Optimus 4X HD came out to 40 hours. That sounds great – it got more than the One X (37 hours), but that’s largely due to the efficient standby performance of the handset.

The large screen on the 4X HD may be great for browsing the web or watching videos, but battery performance simply doesn’t cut it, despite the relatively large capacity of the phone’s unit. Talk time performance isn’t that bad, but let’s face it – these days you don’t buy a quad-core phone with a 4.7″ 720p display for making phone calls.
