The 3100mAh battery unit of the Samsung Galaxy Note II already propelled it to an impressive endurance rating in our battery test. I do however, reckon that there might be some users out there who would appreciate some extra juice at their disposal – just in case they need to jump start their car in a cold winter morning. Mugen Power’s humongous 6400mAh battery is aiming at those Galaxy Note II owners.

The laptop worthy battery unit is scheduled to ship on December 21, priced at a hair less than $100. The aforementioned amount of cash will secure you a battery, as well as a special cover for it with a built-in kickstand. The phablet’s NFC connectivity will remain functional with the new unit.

With the Samsung Galaxy Note II already a hefty device, installing Mugen Power’s 6400mAh battery will make it next to impossible to sit in a pocket. The overall visual appeal of the phablet is another issue to deal with.

A 6400mAh battery for $100, or a duo of regular 3100mAh units with a dedicated wall-charger for half the price? What would you pick?

The latest offering from Acer features a dual-core 1.5GHz Krait CPU, and pushes out an 4.3 inch HD display on Adreno 225 graphics.

It’s seems that this is quite a lot to ask from a 1460 mAh battery, but let’s if it’s up to the task.

Nowadays, most similarly-spec’d devices easily break the 2 Amp mark when it comes to battery backup, so seeing one this much lower makes us wonder if it’ll be enough get you through the day.

Our talk time numbers seemed promising enough, and a rating of 9:05 was enough to put the CloudMobile in the top half of our chart.

Talk time

  • Motorola RAZR MAXX (ICS)21:18
  • HTC Sensation XL9:30
  • Nokia Lumia 7109:05
  • Acer CloudMobile S5009:05
  • Motorola Atrix HD9:04
  • HTC Vivid9:02
  • Pantech Burst4:46

Web browsing wasn’t as impressive, and we saw the S500 fall towards the bottom of the pack. An eventual Jelly Bean update will probably improve it’s endurance, but you shouldn’t expect miracles.

Web browsing

  • Apple iPhone 59:56
  • Meizu MX4:35
  • Nokia N94:33
  • Acer CloudMobile S5004:32
  • Samsung Galaxy S II4:24
  • Sony Ericsson Xperia neo V4:20
  • Samsung Galaxy Nexus3:01

Video playback again leaves us wanting. If you plan on using the S500 as a media player, you’ll get about 5:18 hours of continuous video viewing on a full charge.

  • Motorola RAZR MAXX (ICS)16:35
  • HTC Rhyme5:23
  • HTC One V5:20
  • Nokia Lumia 900 for AT&T5:18
  • Nokia Lumia 900 for AT&T5:18
  • BlackBerry Curve 93805:09
  • Nokia Lumia 7103:27

Finally, standby performance was about average and the Acer CloudMobile scored an endurance rating of 30h.

When all’s said and done, the CloudMobile S500 will get you through the day, but only if you’re sparing in your usage – particularly in video and web browsing. Here’s hoping that next time around, Acer will consider beefing up the battery in what’s otherwise a pretty great device.

So far Motorola has been the only one that can provide huge batteries in smartphones, but Lenovo is about to challenge it with the P770. It’s an Android 4.1 Jelly Bean droid with a massive 3,500mAh battery (200mAh more than the RAZR MAXX HD).

The Lenovo P770 measures 133 x 67 x 11.9mm and weighs 161g (not quite as slender as Motorola DROID MAXX HD’s 131.9 x 67.9 x 9.3mm, 157g). It has a 4.5″ qHD IPS screen and is powered by a 1.2GHz dual-core Cortex-A9 processor with 1GB of RAM.

The P770 is rated at just over 29 hours of continuous talk time and nearly a month of standby. The phone features three power-saving modes: long standby, normal and custom. It also automatically calibrates battery readings to display accurate battery percentages.

It’s not quite clear from Lenovo’s site if the battery is user-replaceable or not (the Motorola RAZR HD MAXX has a non-replaceable battery).

Anyway, the Lenovo P770 also features a 5MP camera with LED flash, VGA front-facing camera, two microphones for noise reduction and a customized Android 4.1.

These specs don’t sound too exciting, but the P770 is priced CNY 1,699 ($273, €210) in China (it’s available now) and you get an 8GB microSD card in the box. For now the phone is available only in China and Lenovo hasn’t announced plans to make it available worldwide.

The Nokia Lumia 820 is our first brush with the Finnish company’s next generation of Windows Phone handsets. It has a relatively small battery (1650mAh), smaller than even HTC’s Windows Phone 8X juice pack. And that one certainly didn’t impress us much with its battery life.

The Lumia 820 has a dual-core Krait processor running at 1.5GHz inside (like most other WP8 phones) so we don’t expect this to make any difference, but that 4.3” AMOLED screen probably will.

Just over 7 hours had passed since the beginning of the call test when the Lumia 820’s juice ran out. That’s much better than what the AT&T version of the Lumia 900 did, but not as good as the 800 or the HTC 8X. The result comes up short of the official 8 hour rating on 3G networks, too.

 

Talk time

  • Motorola RAZR MAXX (ICS)21:18
  • HTC Evo 4G LTE (LTE)7:21
  • Samsung Galaxy S Blaze 4G7:14
  • Nokia Lumia 8207:09
  • Sony Xperia acro S7:09
  • Samsung Rugby Smart I8477:09
  • Pantech Burst4:46

Web browsing usually takes a heavy toll on the battery, especially when there’s an AMOLED screen involved. At about 4 and a half hours, the Lumia 820 goes near the bottom of the chart. Then again, Lumias were never very competitive in this test, but at least it matches the Samsung Galaxy S II, which has a similar screen and battery.

  • Sony Ericsson Xperia neo V4:20
  • Samsung Galaxy Nexus3:01

Finally, video playback is less demanding on both the processor (dedicated decoding hardware does most of the work) and the screen (the image is darker overall, compared to the mostly white websites).

This allows the Nokia Lumia 820 to last for 6 and a half hours, beating previous Lumia phones we’ve tested and matching the HTC Windows Phone 8X. Still, the result is average at best.

Video playback

  • Motorola RAZR MAXX (ICS)16:35
  • HTC Desire V6:26
  • HTC One X (AT&T)6:26
  • Nokia Lumia 8206:25
  • Samsung Galaxy Ace Duos6:25
  • LG Optimus Vu6:23
  • Nokia Lumia 7103:27

The Lumia 820 proved to be quite efficient in standby mode, which helped it achieve an endurance rating of 40 hours (time between charges if you do an hour each of calling, browsing and watching videos).

The Nokia Lumia 820 will get you through the day, maybe two work days if you’re frugal with the web browsing, but hooking up the charger at night will probably be quite common. That wireless charging shell is starting to sound like a must-have accessory for the 820.
