I saw so much he said, she said about battery life on various threads here. So, I decided to conduct my own tests and measure results. I modeled this test after my typical usage i.e. visit various sites and read news/blogs etc. So, no video/music etc was used.
TEST:
- Load 9 sites one after another. On each site, open 10 links. Wait for the page load to finish loading and hit back to go to home page then load another link. So, a total of 90 different webpages.
- Repeat this test on LTE, HSPA+ and WiFi.
- I tests from same location i.e. from Sheldon's seating location (any fans of the big bang theory?)
- LTE had 2 bars with 10 mbps, HSPA+ had 4 bars with 4 mbps and Full wifi rated at 22 mbps.
- All site were bookmarked and I made sure I open the same link for each test by conducting them immediately after the other.
- Browser used: ICS+. Cleared cache, history and cookies before each run.
- Restarted phone before each run to make sure it is loaded with all apps that bootloader would load.
- Device/ROM - I used rooted stock ROM with extensive debloating/desensing.
- Measured battery usage using 'Badass Battery Plus'
- Screen brightness: 35%
RESULTS:
LTE: 14 mins to load all links and used 6% battery (63% battery used by screen)
HSPA+: 19 mins to load all links and used 8% battery (67% battery used by screen)
WiFi: 12 mins to load all links and used 3% battery (53% battery used by screen)
My Takeaway from results:
- LTE doesn't really drain battery much faster but it accomplishes tasks much faster than HSPA+ thus less screen time is used - saving the battery.
- WiFi is the best performer. It is by far the most efficient of all three.
