[One (M7) General] Shan89:
HoX was complicated phone with to many issues , it took over a year for htc and nvidia to fix HoX so I've tried to contribute , as for smartmax I find it bad performing on one it just doesn't work as I wanted it , although I did tweak it a bit when I was on team7 so it was better but still it was very little difference between smartmax and on-demand on stock kernel , I was planing to make another thread for the one but I find it kinda useless , it's not really needed , above screenshots were all with stock kernel , when using ex kernel or any other I get pretty much same / similar results regarding battery but for gaming either one of them with oced gpu is better , also less drain in gaming with uv and oc , my chip is kinda crazy ...I can uv -190 safe and stutery -220 even that I'm bin 3 anyway back to the point my goal on HoX was to get 4/5 hrs average for everyone and it worked as for one pretty much everyone are getting 4/5 hrs average I find it useless to make a guide or tweak the kernel so we gain maybe extra hr , I can for example play a8 for 3:50/4:20 hrs while average HoX screen time was 3:30 / 4:30 so I'm very happy with the one , besides even if I do start a thread I'll need kernel dev to implement pmc governor that I made out of smartmax and that's a pain in the arse since I have to bother them when I update stuff following maxwens work , the easiest way and solution for everyone to have good battery is to simply do what I wrote above and reduce wakelocks if possible for everyone to zero , there's quiet a few apps that can drain battery quiet a lot and cause wakelocks if not controlled via greenify.

Anyway here a little explanation about wakelocks :

Lets take for example my own battery and someone's who's getting lets say average 4 hrs screen time and 13/15 hrs on battery with same or lower usage then mine.

Ok so I lose average per 10 hrs in deep sleep 1/2% while person X loses 10% , if we both pick up phones I'll have 99/98% on battery while person X will have 90% , if we both read xda for lets 40/50 mins I'll lose 8% while person X will most likely lose 10/11% ( due to present wakelocks even in awake time ) so I'll be down to 90% and person X at 79/80% if we leave phones for example in deep sleep for another 10hrs I'll be @ 89/88% while person X will be @ 69/68% with only 45/50 mins screen time and if we use phone again for the same amount person X is @ 58/57% while I'm @ 80/79% and we both have screen time @ 1:30/1:40 except I have almost 80% left and I can get another 5hrs easily with heavy usage till I reach 5/10% and have 6:30 or so screen time while person X will end up with around 4/4:20 tops same usage Thx to wakelocks.

I hope this isn't too messy to read for those who gonna read it lol.

As for kernel on 4.22 I used a lot ex kernel my fav , as for 4.3 I prefer stock until HTC releases the source so Flar can patch the kernel , then I'm switching to ex.

Also I highly recommend greenify ( I'm using free version since my country doesn't support online paying methods nor Google allows it in here atm ) OT : I even had 3 day long fight with my cousin ( he has xz ) about greenify vs stamina mode , finally convinced him stamina mode sux and for stock users who can't have greenify Qualcomm snapdragon guru is quiet good.

Also done tests with camera , one vs note 2 , vs n4 , vs s3 vs xz , I've literally raped them both day and night and video recording.

1st. One , 2nd n4 , 3rd note 2 and 4th xz.

Boot manager is also good from Xposed mods

I've done test with note 2 , my cousin has it , in same usage for 1hr : viber chating , fb chating , browsing , xda , few YouTube clips , sms texting , reading news on same brightness amount 35% for me and 55/60% note 2 since our display is 20/25% brighter then note 2 I've lost 13% and note 2 lost 18% , in 1hr asphalt 8 gaming same tracks everything same I've lost 18% note 2 lost 26% , one does have stronger battery then note 2 , it's just most of the ppl use auto brightness and one @ 100% is like note 2 @ 125% if we cap our brightness @ 75% we will do better.

Theres somewhere a test on gsm arena I think , one can play video for 10:41 if I remember right while note was @ 11:30 , when they measured max brightness on note 2 and then set one to the same brightness lvl as note 2 one reached around 13 hrs.

As addition to screen technology as we know amoled uses less on black background etc while ( not sure about this tho ) it uses 2x more then slcd3 on any other color if you think about it 95% of the time you're not on anything that is black except for the text. So in fact better battery saving screen tech is ips.
