[Nexus 6P General] xperator:
Xperator's guide on how to get 5+ hours of SOT on N6P

I've decided to share my knowledge on this subject so newbies like me can taste 5-6+hours SOT on their device.

Its not really that difficult, you should try all sorts of things to find your sweet spot. I've spent several weeks trying different ROMs, Kernels, Governor profiles,etc... To find my sweet spot for the battery life.

These are my personal tweaks. They work for me and guarantee a minimum (yes a minimum) of 5hours SOT (no matter what you do).

But beware! even if you copy this, you might not get the same results. Cause you know, we have different usage habits, different environment, and tons of factors that affect the battery life.

This is for people who barely can reach 3-4hours SOT. If you are already above the 5hours line, you probably dont need this.

First things first, make sure your battery is fine. Maybe its physically defected or something is wrong with it?

To make sure your battery is fine, Do a clean install of any ROM. Install a minimal Gapps, don't install your personal apps. Use the phone for sometime and see if the battery is dropping too fast. If so then you should return it.

If you dont want spend too much time. Just make sure you are getting +30min SOT for every 10% of battery power you're losing.

Important

- Always do a clean install. It means go to TRWP, the Wipe menu, Advanced wipe and wipe everything except Internal Storage

- Try UberStock (its a ROM) at least once. You might get to 5 or 6hours of SOT without proceeding to next steps.

- Uninstall the Facebook app. Use a browser or an app like Folio, Tinfoil,etc... to check your FB.

Now we get to the main part. Follow these steps.

1. Flash your favorite ROM. I recommend ResurrectionRemix and PureNexus.

2. Flash the latest Open Gapps Nano package. you can find it at opengapps.org

3. Flash the latest vendor image

4. Flash latest Kylo kernel. I recommend the Uber6.0 branch.

5. Reboot. During setup uncheck the part asking you to share location and send analysis info.

6. Install your personal apps.

7. Disable NFC if not using

8. Install Ex Kernel manager. Go to Misc and change IO to SioPlus and Readahead to 2048.. Make sure to check Apply on boot for all the things you changed.

9. Reboot the phone. (not Soft Reboot). After reboot you should already expecting some great battery result. Why? Cause you got rid of the bloated Gapps and You are using the awesome Kylo kernel.

If you still not having your desired results, continue to next steps.

10. Start using a profile. I'm talking about the advanced interactive governor profiles. Try every profile you can find out there. I recommend DarkSpice7.5 and GhostPepper for the start. If you are a heavy user or a gamer go for DragonFly.

You should let the battery drain to below 5%. Dont be impatient. Keep a note of SOT at different battery percentage so you can compare profiles later. Also make sure to add a side note when you had long phone calls or when you are on the go. These 2 cost you lots of SOT.

Still not satisfied? Continue reading

- Check your apps cpu usage. Install an app like OS Monitor and see which app is using your CPU the most. Some apps might be sucking your cpu's power in the background. Even when they are closed

- If your ROM comes with AppOps (PureNexus does) open it and

Disable the Coarse Location and Keep awake for any app that you know is waking up your phone or does stupid location seeking in the background.

I think thats enough for now. Special thanks to [MENTION=5323968]xSilas43[/MENTION] and [MENTION=5169465]DespairFactor[/MENTION]
