I ran yesterday’s freeware recommendation, Battery Eater, to find out the minimum battery life of the Samsung Q1. Yes, you read that right, this checks the minimum life by stressing the computer’s hard drive, RAM, graphics card and CPU. The assumption here is that you’ll get more more battery life than this test will show because you wouldn’t likely use your mobile device at 100% of its resources 100% of the time. I should note a few things right up front on this first run.
- My Q1 has 1 GB of RAM, per the self-upgrade two months ago.
- I inadvertently had the WiFi radio OFF; I’m running the test again later today with WiFi on.
- I’m using the "Max Battery Life" power setting provided by Samsung’s Battery Manager application.
- The Bluetooth radio was not disabled, but was not used during the test.
Battery Eater reported back a minimum runtime of 1:44:45, which makes sense to me. I routinely get 2.5 hours of battery life by proper power management, so a minimum of 1 hour and 45 minutes makes sense. Shown below is the battery discharge graph; note the sudden drop-off in the last 10 minutes, which jives with jkOTR reader, JKK’s findings:
Speaking of JKK, the same test was run on a Amtek t700 and returned a result of 1:28:15. Again, not surprising as those UMPC models have a 26 W/hr battery, while the Q1’s 29 W/hr battery has approximately 10% more capacity. Interestingly enough, the minimum time difference is actually 20%, but remember, I had my WiFi off; JKK had the WiFi on, which is why I’m running the test again later this morning. Other factors, such as the amount of RAM could come into play as well.
