Please check my Galaxy S2 battery usage?

I'm on CyanogenMod 9, ICS 4.0.4. My original 1650mAh battery hasn't been too stellar, and below is my usage:

- In deep sleep, it loses about 1% per hour, sometimes a bit more. I usually wake up to a 8-10% drain.

- With web browsing over wifi, it loses about 1% per 3 minutes. Which means a fully-charged battery runs dry after 5 hours.

- Games use around the same amount of battery as wifi browsing does, probably a bit higher depending on the kind of game. Max Payne is probably the most demanding game I have on my phone, and it drains a full battery in 4 hours.

- Charging via AC from 0%, by estimation, takes about 3 hours. USB charging is slower, at around 4-5 hours.

- In battery settings screen, the display takes up around half the percentage at any time.

My settings for the phone:

- Brightness is manual, at 10-20%.

- Mobile data always off unless I turn it on.

- Wifi off when not used. Wifi sleep policy set to never, however.

- Mobile network on 3G.

- Syncing set to off, both Google and Facebook accounts.

Diagnosis with CPUSpy and BetterBatteryStats shows that:

- My phone is in deep sleep the majority of time it's not used. Overnight it would stay in deep sleep around 95% of the time.

- I don't have a wakelock problem as far as I can tell. audioout_1, fuel_alerted and other common wakelocks are rare.

So fellow S2 users, what are your thoughts? Is this battery usage normal?
