I just bought a new HTC One S since my Nexus 4 is busted. I installed CyanogenMod 10.0 and then 10.1, and I noticed that with either the stock rom or CM, the battery drains about one percent per hour. Is this typical for the HTC One S? I suspect it's because the phone is new but is old stock and hasn't been used for a year or whatever in storage.

Mine is about 5-8% overnight on WiFi snagging emails and notifications but I've had mine since release week. Tbh I don't remember what it was like last year.

One percent per hour is decent, but 'idle' means different to everyone. Do you have email accounts checking every 30 minutes, how often do Facebook/Twitter/other social media apps update, etc.

Also, did you give the new ROM a few battery cycles to settle down? I noticed that I didn't get the 'true' battery length on my HTC One until more than a month after flashing a new ROM. In fact, after more than two months after flashing I could still see an improvement in battery performance. However, to be able to do a quick review, at least give it a five full (100%-20% at least) cycles to judge battery performance after you flashed the ROM.

I usually lose 5-7 hours over night on my One, but if I really wanted to save I could turn off wi-fi and mobile data (essentially airplane mode with phone radio on) before I go to sleep and I'd only lose 1-2% in 6-7 hours.

How does a battery settle down after flashing a ROM?

Android has something called battstat, or at least they use to. After a rom flash letting it charge to 100% then go to 0% then wiping and letting it charge back to 100% made a difference. I don't understand stand it, but it works. Not sure if Google has changed things since the battstat days. I once called HTC support about the battery/rom thing and was given some of the craziest directions to help battery life I've ever heard. Android has(had?) some oddball techniques to improve battery life.

The battery stats crap is a myth. See https://www.xda-developers.com/andr...-battery-stats-does-not-improve-battery-life/
