My battery life from yesterday.
14h battery life with 11h of screen on time.
Minimum brightness as much as possible, only on auto when outside
Xreality off (don't like how it oversatured colors)
All music enhancement off (il like to listen to my music as it was meant to be by the creator :P plus it reduce power consumption! Double win hehehe)
Stamina with restricted performance when battery reach 40% (i'll explain what this setting do and how I use it later on my post)
And no custom rom or kernel, all stock with the last 314.
My use from yesterday
40min of call
4h of video playback (on streaming, with youtube and other apps)
Whatsapp and viber all day long
A couple of photo with 8mp manual mod
And internet browsing,fcbk,twitter etc all the rest of the time.
So... THIS PHONE ROCKSSSSS
Usually I get most of the time at least 8-9h of SOT time with 18-24h battery life, and I am a heavy user.
When I play game's like injustice or real racing I just activate restricted performance (under stamina settings), on this mod CPU governor change to a more conservative on and framerate is limited at 45fps (this is more than enough for a mobile game) and this prevent the phone from overheating!!
I also do that when I watch movies (movies and videos are at 24fps so you won't see any stutters or lags, and this with xreality off really improve power consumption, I lost barely 5-6% on 1h of streaming video!!)
I think that with this kind of battery life no need to mod or unlock this phone
hope I can help people getting a better battery life by sharing my founds and my settings and sorry for my english
