A few friends, blog readers and twitter followers asked me about the battery life of Samsung Galaxy S in the past few days. Me too was interested to know what is the battery performance under extreme usage. Besides, I’m sure potential customers would like to see some statistics so that they can stop wondering about the battery performance of Samsung Galaxy S.

Therefore, I performed 4 battery tests 5 battery tests in the past 30+ hours 40+ hours and finally we have some answers to the battery related questions. Below are the objectives of all 4 battery tests I did :-

• Test 1: Find out how long will the battery last (from 100% battery level to 0%) when connecting to an active Wifi Connection
• Test 2: Find out how long will the battery last (from 100% battery level to 0%) when connecting to an active 3G Data Connection
• Test 3: Find out how long will the battery last under continuous movie playing
• Test 4: Find out how long we need to fully charge the battery after it’s completely flat (0% battery level)

* Just added 1 more Music Playing (Test 5).

Final Battery Test Results (now with Music Playing result)

General settings for all 4 tests

• Lowest brightness level
• Medium speaker volumn
• The screen is always lit throughout the tests
• Not running any screen saver

Test 1: Active Wifi Connection

• 1. Connect to an online radio via Wifi connection
• 2. Let it run until the phone switches off when the battery is depleted

Result: The phone was running for 9 hours 57 minutes before switching off itself.

Test 2: Active 3G Data Connection

• 1. Connect to an online radio via 3G Data connection
• 2. Let it run until the phone switches off when the battery is depleted

Result: The phone was running for 4 hours 47 minutes before switching off itself.

Test 3: Continuous Movie Playing

• 1. Continuously play some movies using the default movie player
• 2. Let it run until the battery level reaches 10%

Result: The phone was running for 6 hours 29 minutes before the battery level reached 10%. Movie player will stop running when the battery level falls to 10%. 6 hours 29 minutes of continuous playing time is more than enough to play 3 sets of movies at normal length.

Test 4: Charging Time

• 1. Fully charge the phone using original Samsung Travel Charger after the battery was completely depleted

Result: The phone needs 3 hours 47 minutes to get fully charged after the battery was completely depleted.

Below is the video documenting all the 4 battery tests :-

Test 5: Continuous Music Playing

• 1. Continuously play some songs via earphone using the default music player

Result: The phone was running for 13 hours 9 minutes and we still have 39% battery level. That’s about playing 263 songs of 3 minutes long each!

I hope the results of the above battery tests are useful and help to clear doubts regarding Samsung Galaxy S battery performance. Now at least we have an idea how will the battery perform under extreme usage. As for normal usage, the phone should be able to last for the whole day under occasional Internet surfing, email checking, photo & video shooting, viewing video and listening to songs.
