No nougat and my phone is getting really hot!

[Zenith49]

My battery is running down really fast - like I'm lucky if I get 5 hours when it used to go nearly all day and it's getting really hot sometimes.

I bought a replacement battery, but I'm chickening out doing the install. A) it's hella complicated and 2) I did this with a Nexus 4 and it didn't help. The replacement battery wasn't any better than my original.

And I'd like to sideload nougat. How and where do I do that? BTW, I'm on Project Fi.

TIA

As usual with these kinds of issues, it's helpful to see some battery stats. Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:

1. The main Settings>Battery screen.
2. The fullscreen battery graph screen (which shows Awake time and Cell Signal Strength).
3. The Screen category (to see total Screen On time).
4. The Cell Standby category, if present (to see Time Without Signal).
