Is that necessary? To force the bat cap? Do you have a link for the batteries/charger?
I have no idea if its necessary haha just saw the option the other day so I did it when I got the battery.

It takes about 4hours to fully charge, the light turns blue when its finished fyI

Do you think using a Sense ROM would help? For me its definitely something wrong with the radio here. On WiFi I can go all day even while I set it to Never Sleep, but once I use data it is horrible.

I'd like to chime in here because I fall in the camp of deflating battery life quickly :)
I've tried lots of different roms (AOSP and Sense), different kernels, different radios, different governors, and lots of combos therein.
I never get as good of life as others.
I have noticed a few improvements.
I have used juice defender and 2x (currently on 2x).
I turn them to never check unless screen on. I decided I check my phone often enough to get the info I need with a data connection without it going out and looking.
Just yesterday in the main CM7 thread I found out about checking 'partial wake' in battery history in spare parts.
I have an exchange account using enhanced email and it was set to 'push'. It was causing my phone to be awake even if the screen was off.
My guess is it remains checking for some period of time after screen off and this accumulates over time. I notice my 'awake' time has dropped off a lot.
If I put the phone in airplane mode and leave it for the night it won't budge but maybe 1%.
With data off but cell standby on, it would drop 10-15% just sitting there with the screen off.
So last night with the partial awake issue silenced I tried again with cell standby on, data off. It was better at about 5%.
However, reviewing the usage this morning I was kind of expecting the awake time to have followed the screen on time.
BUT there was a rather large chunk in the middle of the night when it was awake. It wasn't a steady interval.
I'm using the latest 2.11 radio and seem to get great signal.
Based on what I've said above does any one know what caused the awake time in the middle of the night?
Is this the signal being to weak? (despite it being in the same spot)
Anyway, the more I read about battery life and what I've seen I think the actual cell and data signal are the main culprits.
We might be running the same rom, kernel, governor, and radio and get completely different results with similar usage.
I think the tbolt just doesn't handle poor signals well and really chews it up if you are in an intermittent to poor area.

is it autosync? That will use a good amount especially if you have Facebook, twitter. Google services and email also sync. Check what you have syncing, if your using paid juice defender you can set different options for autosync

Running cm7 rc1.6.1 with the latest ota radio and the latest jdkernel (smartass gov) . First day using it. 8 hours on battery and its at 70%. Not too bad.

I'm using Green Power for data off when screens off and setcpu profiles (245/368 min Max when screen is off on powersave gov).

With the right tweaks, cm7 can have pretty good battery life.

Usually I have my phone on the charger 90% of the time but this weekend I am going to do some tests to see about battery on AOSP (More specifically OMFGB, 8-25 release, jd's latest kernel). Slightly undervolted, with clock frequency 245-1408. Will post results as the weekend goes on.

This is without any batter saving programs (2x battery, Juicedefender), on a standard battery, and 4G the whole time, with a fresh battery.

here's what has worked best so far that gives me enough speed and I feel satisfied with my use.
CM7 1.6.1, tiamat 1.10 kernel, interactive governor, 2.11 radio and min/max cpu set at 268/1036 MHz.
I run 2X battery and have it shut off unless screen on. It has a new option that it won't turn on unless you unlock the lock screen.
This lets me check to see if I have texts without grabbing data.
I had an issue with enhanced mail going partial awake even though I told it to never check mail unless I sync.
It was working but the latest update messed that up.
There are still programs and/or services that are waking my cpu when I have screen off and data off.
Ideally (for my needs) I like to only have texts and voice calls available when the screen is off.
I would want everything else shut down. I check my phone often enough to get the data I need when the screen is on.
In my mind this would extend my battery life quite a bit.
From what I can tell in battery statistics, the awake hits I'm getting are network usage by the android system.
It SetCPU an app that will allow me to prevent apps from running in the background when the screen is off?
Thanks

I think to accurately depict usage (heavy, moderate, light, etc), certain stats should be listed.
Mainly, time up on battery, running %, screen on % and probably wifi% (all under 'other usage')
Mine could last forever with no data and the screen on at 1% :D

I've had this problem for a while to the point where I could hardly get through the day any more. I decided to finally try a sense rom and battery drain has gone to what I would consider normal.

It's unfortunate because I love cm7 but aosp roms rape battery for some reason so I'm sticking with sense for some relief. Wish someone could pinpoint the difference the sense Tom's provide but it's a drastic difference. Like 2-3xs longer life of a standby phone.

I agree that sense ROMs offer better battery life. I guess it all depends on how you use your phone. For me, I use my phone heavily at home mostly, with wifi and a charger near by, so aosp ROMs are ok for me.

Figured I'd post up my last charge:
Cm7 1.6.1
Latest leaked radio
oem extended battery
Wifi on all the time (set to stay on when screen is off)
KangBang 1.0 BFS at 1ghz, ondemand
I use the phone a decent ammount, and use data constantly (remote desktop, and tether my iconia to it for work). I also use it as an mp3 player whenever i'm in my car.
Just got 3 days, 3 hours, 15 minutesbefore plugging it in. Phone was at 4% remaining.

This is with an exchange account,and 2 gmail accounts set to push.
Facebook and Google+ notifications off (pointless to have them on with email notifications setup), and manually running ATK (pretty extensive ignore list setup for system apps).
Also, i disabled (deleted) dsp manager. While it's a neat feature, i found it absolutely destroyed the battery.
