There are several apps, but I use this.
I forget which nightly I'm on, but it works great. TPs are set at 1.2, but I clock it at 1.5. Does the job.
I run Greenify too to force close everything upon close.
How long are you gonna be reading at a time? /u/ADH-Kydex didn't say whether he used No-frills CPU Control, which can underclock its processing speed (as well as alter its hardware profile governor) to save battery. I think with no WiFi, underclocking, and maybe 30-60 minutes of daily reading (that's a conservative estimate), accompanied by powering-off whenever it's not used for more than half an hour since each last use, it could last two weeks on a single charge.
NSTs have been discontinued for years (since Feb. 2014). The battery life has probably degraded since then and I doubt you will be able to get the original purported 2 months.
nofrills performance and max. min 800 or something 896. you'll see the option.

You could try No-frills cpu control, I use it both on my LG L7 II and my Galaxy Tab 3 and it works like a charm. Check compatibility first, though.
Thes apps (Root acces and custom kernel required). Try this:
No-frills CPU Control(Google Play, apk)
AnTuTu CPU Master(Free)(Google Play, apk)
CPU Control Free(Google Play,apk)
Kernel Tuner root (from XDA forum) Root is required Custom kernel is required. (Google Play, apk)
How would I do this? Does an app like this work? What governor should I choose?
