Battery this. Battery that. Man, is it getting old!
* Anyone switching from a 6.1 ROM to a 6.5 w/ Rhodium is going to notice a drop in battery life. Welcome to 6.5, get used to it, quit blaming the chefs.
* Anyone who switches from a lightweight stock-like ROM to one loaded with apps and features that run in the background all day long is going to notice a drop in battery life. Welcome to reality, get used to it, quit blaming the chefs.
* Anyone who installs high-performance software like EnergyROM, but fails to implement well known power-saving tweaks is going to notice a drop in battery life. Welcome to free will, get used to it, quit blaming the chefs.
Some chefs will cook their ROM with all the known power-saving tweaks, and some gear for performance instead. A chef could claim to do both, and attempt to do both, but in reality every tweak is a trade-off of some sort -- a little give here, a little take there. That's life. For example, EnergyROM is cooked to operate with the backlight at 100% while on battery. Now, that looks great, but do you have any idea how much *extra* power that sucks? Here, for your perusal, are some 'current' values from tBattery while the phone was idle (unscientific random samples):
Think about that for a minute. At idle with the backlight unchanged after a flash, your current pull is 50-100% more than it would be if you just reduced the backlight somewhat. Do you keep your phone in your pocket? If you do, I bet you have a screen protector like S2U2, or Pocketshield, or are using the built-in WM lockscreen -- well, everytime it 'bumps' something and wakes up in your pocket at 100% backlight, guess what is happening...drain drain drain...
*** Anyone who thinks they have noticed a
significant ROM-based difference in battery life between the recent EnergyROM builds is a shining example of how misunderstood is the whole battery life issue. Can you say Placebo effect? A chef could 'say' they cooked in new battery-saving features and a percentage of the community would report back that it's true. NRGZ28 has stated already that there are not any major changes int he recent build variations that should have impacted battery life. So, unless you are convinced that the SYS/XIP updates are causing massive fluctuations in battery performance, you gotta stop suggesting that 'this build' has good battery life and 'that build' has bad battery life -- it just aint like that.
Ok, so you want something more technical than all that...how about this post from
