South Korean Scientists Claim to Enhance Li-ion Battery Life by 300%

BatteryThe biggest bottleneck in a modern day smartphone is its battery. Within just a few years we have gone from single core processors to quad and octa core gigahertz monsters, WVGA to full-HD displays, and 3G to 4G connectivity. However, the battery technology has been struggling to keep up. LG Optimus G, which touts latest innovation from LG Chem, has a battery rated at 3140 mAh. That’s more than double that of what Xperia X10, a handset released more than three years ago had. However, even that probably will not last a day of reasonably heavy usage. No matter which smartphone you use, your battery probably won’t last 24 hours.

Researchers around the world are attempting to come up with a battery that can meet the demands of the next-gen smartphones and other mobile devices. The good news is that a group of scientists might have made some headway in Seoul, South Korea. A team led by Prof. Hyun Taek-hwan of Seoul National University claims to have increased the capacity of a lithium-ion battery by up to three times by using a nano structure of iron oxide and manganese oxide, instead of lead, as the cathode of the battery. The new battery is also believed to be more efficient, losing only 0.5 percent its performance even after numerous recharges.

HTC: Customers Prefer Thin Smartphones Over Better Battery Life

HTC phones are known for their poor battery life, and it looks like the company just got a valid excuse to use lower capacity batteries in its handsets. According to a survey done by HTC, customers prefer a slimmer phone compared to those which had a beefy battery but were bulkier. HTC Vice president of product strategy, Bjorn Kilburn, says that due to this the company shelved its plan of releasing phones with 3000mAh+ batteries.

I am not really sure what kind of people HTC surveyed, but I can vouch for nearly every Android handset owner out there that they will prefer a thicker phone with better battery life compared to a slim phone that barely lasts a day. Kilburn did state though that this does not mean HTC is not trying to improve the battery life of its handsets. He stated that the One X is the first phone from the company to pack in such a big battery inside a 9mm body, so as to make sure the device lasts through a day of moderate use.

Time to stop dreaming about a HTC One X with a bigger internal battery then!

Mugen Batteries Review For The Samsung Galaxy S And HTC Desire Z

Poor Battery life is one of the major issues with most of the Android phones out there. Previously, I wrote about an app called Juice Defender which helps in increasing the battery life of Android phones. However, tweaks and apps alone cannot make up for low capacity batteries in Android phones, especially from HTC.

Under heavy usage most of the Android phones will hardly last a day. Due to this, many hardcore Android handset owners buy a third party higher battery for their handset. These third party batteries come in two flavors one without an extended back cover and another one with a back cover, which usually adds a couple of inches thickness to the phone.

Mugen Battery is one popular third party high capacity battery manufacturer. The company has high capacity batteries available for nearly all Android, WP7 and Symbian handsets.

Recently, I got trial units of Mugen battery for the Samsung Galaxy S and the HTC Desire Z.

For the Samsung Galaxy S, Mugen offers two batteries one with a 1650mAh capacity, and another one with a whopping 3200mAh capacity and an extended back cover. Similarly, for the Desire Z, Mugen offers an 1800mAh battery along with a 3600mAh battery and an extended back door.

First up, the review of both the Mugen batteries available for the Samsung Galaxy S.

The 1650mAh battery from Mugen only has a slightly higher capacity from the OEM Galaxy S battery. I tried the battery with several different ROMs including CM7 and the stock ROM, and managed to squeeze out couple of hours worth of extra battery life compared to the stock/OEM battery. With the stock 1500mAh battery from Samsung, I get around 11 hours of battery life on 3G without Juice Defender.

The second 3200mAh battery from Mugen for the Galaxy S is the real show-stopper though. The extended back cover with the 3200mAh battery does make the Galaxy S noticeably thick, and heavy. However, the build quality and texture of the Mugen back cover is also better than the stock back cover from Samsung. It also helps in improving the grip on the SGS.

With this battery, I managed to get more than 2 days of continuous usage or heavy usage. With more than 4 hours of voice calls, a couple of hours of Tank Hero and Tilt Arena, and an hour of browsing on 3G, the battery lasted me 2 days 10 hours before dying.

The 1650mAh battery is a great buy for anyone who is looking for a spare or a replacement battery for his Galaxy S, without increasing the bulk of the phone.The 3200mAh battery is an easy recommendation to any Galaxy S owner who travels frequently, and is rarely around a power source.

Now, here is the review of the Mugen batteries for the HTC Desire Z.

The 1800mAh battery for the Desire Z from Mugen is a pretty big improvement over the stock 1300mAh battery, capacity wise. With the stock battery, the Desire Z lasts me around 14 hours on 3G with some heavy gaming and tweeting with 1 Gmail, Facebook and Twitter account syncing in the background. With the 1800mAh battery from Mugen, I was able to squeeze around 21 hours of battery life on more or less the same usage as stated before.

An increase in battery life by a whopping 7 hours, without replacing the battery cover is a huge improvement. I wonder if Mugen can fit in an 1800mAh battery, why does HTC ship a measly 1300mAh battery with the Desire Z.

The 3600mAh battery along with the extended back cover, when installed gives the Desire Z a very weird look. Unlike, the Galaxy S, the extended back cover on the Desire Z only covers a part of the handset. This is not a fault of the Mugen though. The Desire Z was never made with an extra-thick battery door in mind. The Mugen battery door is made up of plastic, unlike the original metal back plate found on the Z.

Now, like its lesser capacity sibling, this 3600mAh battery packs some serious punch. The Desire Z lasted a staggering 3 days and 5 hours, with still 10% of charge left. I used the phone for around 6+ hours of music via earphones, nearly an hour of Internet browsing on a mix of 3G and Wi-Fi, lots of tweeting with 1 Gmail, Facebook and Twitter account syncing in the background.

Readers should keep in mind that battery life will vary depending on their usage, but even then they can easily squeeze out more than 40+ hours of battery life from the 3600mAh battery.

I can easily recommend both the Mugen batteries 1800mAh and 3600mAh for the Desire Z. The former costs $44.95, while the latter costs a whopping $96.95.

At the end of this review, I can easily say that Mugen Battery is the best third party battery available for your precious phone. Not only do they increase the battery life substantially, they are also available in different sizes according to a users need.
