Hi guys,
Do we have any confirmed tips on how to improve the battery life on the Nexus, without sacrificing email, SMS, MMS, & text delay?
It requires root, but I've been served relatively well by underclocking my phone on the stock kernel, using SetCPU and some practical profiles.
This doesn't disrupt anything, and it ensures nothing gets out of hand when not using the device. Again, I've set various profiles for underclocking to take place during screen-off events, such as sitting idle (obviously), but also while on calls (since I'm unlikely to be multitasking). I figure the little periods of smart underclocking and proper app settings, serve to extend battery life that much more.
That said, I piggyback this with Juice Defender, though not with any type of heavy setting. Like you, I don't want much disruption from my incoming messages, so I'm fine with 5-15 minute intervals of no data (it isn't a dramatic savings in battery life, but 25% helps).
Also, the 4.0.4 update finally addresses the Android OS battery draw bug (at least from what I've seen/tested), which I'm hoping helps to improve battery life in the longrun. However, it's too soon for me to tell, but my fingers are certainly crossed.
All in all, I don't detoggle LTE, Wifi, or bluetooth, as I couldn't be bothered. Everything works as I expect it to and I get through the waking hours just fine, with normal usage.
