SM-G920P - how to get better battery life? - Galaxy S6 Q&A, Help & Troubleshooting

My S6 is 1.5 weeks old. I have it rooted, using greenify, etc. The battery seems to drain faster than I'd like.
Any thoughts as to how to dramatically improve it?

[Xperia Mini ST15i] What rom is better for battery life

I am currently with RealICS rom and MESA kernel but it seems the battery is draining way too fast, especially when in call, after 4-5 minutes it drains like 2-3%.
So please tell me if GB would be better for the battery life, or it all depends on the kernel?
I would like to know that too. What kernel and ROM should I use to have best battery life. I use GPS allot and it drains battery pretty fast. Thanks!

[Q] Rom with best battery life

Hey guys,
is there a rom with a better battery life than stock rom?
What is the rom with the best battery life?
Thanks for your help!
I tried both paranoid android and cyanogenmod for a few days. Paranoid is very good for battery life, but I don't really think it's that much better than stock.
I'm running stock right now and I'm perfectly happy with it
I have found that stock gives the best battery life, which can be further improved by using Greenify. Currently getting 2 - 3 days with average usage.

[Q] ROM + Kernel for Best Battery Life?

Hey I'm looking for the closest to stock ROM with the best battery life. Im not sure if i should stay stock and rooted (6.0.1) and go with franco kernel or switch to CM 13 (CAF?)...or something else even.
Id say my usage is about average, minimal usage while working, probably less than an hour talk time per day. Maybe 1-2 hours of screen on using various apps (browser, light games, news apps). Generally i make it through a day with about 20-25% left before i goto bed and plug it in to charge every night.
However when i do make more use of it the battery seems to deplete pretty fast. Ideally i would just like better battery life, its the primary reason i havent upgraded the phone yet. I dont need a faster phone, i need one that gets significantly better battery life.
Any recommendations would be great. Thanks

Your mileage will vary greatly depending on usage and what apps you use.
I have personally found that a good kernel is the key to good battery life. I'm a fan of Cataclysm and ElementalX personally.
Best battery life is with stock rom + stock kernel. Before i used custom kernels, but over a week now i have used stock rom with stock kernel and i must say that i get better battery life than before with customs. IMO.

Which kernel do you suggest for BEST battery life on G920F?

I've tried some of the kernels which are produced for S6 (G920F) in xda but after a while battery life gets worse and worse. It sometimes gets so bad that while screen is off (just music plays) battery level decreases and I can't understand the reason from the "Battery Usage" screen in settings. I know, it's related with both ROM and kernel, but I'm using Alexis ROM (and arter97 version 20.0) nowadays and I love it. Can you offer me the best kernels about power efficiency?
I'm using arter's kernel v20 too, but with Xtestrolite ROM and have quite a good battery life, playing Spotify all day and doing moderate browsing.
Do you find Alexis ROM better for battery life? Haven't tried it yet.
It's not worse than XtreStoLite ROM but I can't say better than it. How many hours SOT for you? Can you upload a screenshot here when your battery is at %1 or somewhere like that so that I can analyze how is your usage and is it efficient.
I can only do it on Thursday tho, got no time until then. Will edit once I get the screenshots. Also, I'm on Xtrestolite 3.2, not latest, too lazy to update.

Would flashing a new custom ROM improve battery life

I'm currently using stock MM rom and I'm not really pleased with the battery life so far. I can't last a day with a full charge and the battery drains somewhat fast. Call it placebo but I really think there's something not right. I tried doing a factory reset before but the results are still the same. Now my question is, would rooting and flashing a custom rom perhaps help alleviate the battery life situation by a bit. Maybe say some kernel has better battery performance or so? I don't want to root my phone just for the sake of testing it out. I hope someone could provide some real experiences with the performances of custom roms so far. Thanks!
Rooting didn't do much to mine. Not even using Greenify
