The Samsung Galaxy S3's battery was recently tested by GSM Arena and the site found that it was good for 10 hours of talk time.
The 10 hours of talk time was achieved with the Galaxy S3 while the display for the handset was off.
Other results included 5 hours and 17 minutes of web browsing, and over 10 hours of continuous video playback.
According to GSM Arena's data, the Galaxy S3 fell just behind Motorola's Droid Razr Maxx on video playback and talk time. And in terms of web browsing, the smartphone ranks no. 14 behind many other competitors thanks to its AMOLED display.
The Razr Maxx's main attraction is the new 3300mAH battery that was added to it. Other than that feature, the device is almost identical to the original Droid Razr.
The report also stated that with the Galaxy S3's stand-by endurance rating of 43h, users would need to charge the smartphone once every 43 hours if they want to do an hour of 3G talking, video playback and web browsing per day.
Samsung unveiled the long awaited Galaxy S3 at its "Mobile Unpacked" 2012 media event earlier this month that took place in London, England.
Specifications on the handset include a 4.8-inch HD Super AMOLED touch-screen display, an 8-megapixel rear camera, Android 4.0, Ice Cream Sandwich and NFC (near-field-communications).
The Galaxy S3 also has a new Siri-like feature called S Voice that performs various tasks on the device by listening to voice commands.
"The GALAXY S III features 'S Voice,' the advanced natural language user interface, to listen and respond to your words. In addition to allowing information search and basic device-user communication, S Voice presents powerful functions in regards to device control and commands," said Samsung.
