SlimRoms' website has been experiencing technical difficulties for the last month or so, but it's good to know the team is working hard and is still on top of things. The SlimRoms GitHub repos are getting updated with some major changes showing up. Most notably, some projects are getting a new 5.1 branch: lp5.1! A new, revamped and open source website is also in the works, with a look inspired by material design. We also got a tip about an...
Nexus S Battery Study Part 2
Not long ago, we brought you an in depth study of the battery life of the Nexus S by XDA Senior Member bedalus. It included a very nice spreadsheet that documented battery usage for a variety of things such as benchmark tests and listening to music, and measured—if a little crudely—the actual battery savings from popular features such as deep idle and undervolting.
Despite warnings to not try it at home, XDA Forum Member nathanson666 put together some more sophisticated equipment and had a go at it anyway. Nathanson666’s mission was to prove whether or not Deep Idle, or DIDLE and Screen Off Max Frequency, or SOMF, saved as much battery as previously speculated using this really cool gadget.
Through the study, nathanson666 used the Nexus S music player to gauge the success, or failure, of DIDLE and SOMF by gauging how much battery life a song took and using those same songs to measure with DIDLE or SOMF turned on or off or both turned on or off. The results pretty much speak for themselves, as DIDLE and SOMF used in unison definitively showed the greatest battery savings over either one being one alone or both turned off. In some cases, by quite a bit. Says nathanson666:
DIDLE: no SOMF: no 194.5413mW average power
DIDLE: no SOMF: yes 314.7844mW average power
DIDLE: yes SOMF: no 133.747mW average power
DIDLE: yes SOMF: yes 126.4452mW average power
This basically means both features turned on yielded the best battery life and Deep Idle off with Screen Off Max Frequency turned on yielded the most battery drain. This conclusively proves that both features work to reduce battery drain based on the “race to idle” principle.
For anyone who wants to check out the full study, you can read up on the original thread from bedalus or just skip directly to the post. There you’ll find graphs, and a great .zip with all the data and scripts that nathanson666 used to measure the battery.
And don’t forget, it is absolutely not recommended that anyone do this at home as it can permanently and irreparably damage your device.

ASUS has built a solid name over the years for their computer components, but in the last few years they have been expanding into the mobile market. With their Transformer series of tablets, their Padfone line, and being the tablet manufacturer for the Nexus 7 (as well as the 2013 version), they've solidified their place as a viable option in the mobile industry. In the 4th Quarter of 2014 they announced their ZenWatch, and at the beginning of 2015 they announced...
