I'm using the miui rom with the included kernal which i think is the cyanogen kernal
Sent from my HTC Incredible using XDA App

you should try to restore through CWR to a good setup. then reflash miui and try the ziggy bfs kernel for the inc i think it is 2-JAN-2011 version it is sick how good it is for battery life.

Something might be draining your battery.
Even I've noticed many times, battery gets decreased while charging and playing games. Please don't use your mobile while charging. It can effectively improve the time it gets fully charged.
It's been my personal experience.
Or put in airplane mode over night to charge it effectively.

you can change an USB line
if no use, put mobile in airplane mode or shutdown to charge
(sorry for my poor english

I've been using it for a while and I had no issues. So absolutely not a kernel issue.

Battery fast charge and discharge

I have prolem that phone discharges normaly from 100% to some 70% and then rapidly discharges from 70% to zero. Batt graf shows vertical discharge.
Similar thing when charging. It charges to some 30% for an hour and than from 30% to 100% in a minute.
I have read tons of threads, did batt cal, delete batt stats when bat was 100% and when batt was 0 % few times, did s-off, change bootloader, tried few roms. Always the same.
Is this behaviour because batt is dead? I dont have spare batt so before ordering new one I want to ask did somebody experience similar situation?
Thanks.

upload the graph, how old is the battery?

You can try another ROM and look if the problem persists though I guess that's not a problem of any ROM... I think it's the battery.

I will try to upload graph. I have screenshot of charging graph but I must dischage battery again and take screenshot because there is no discharging graph after wiping bat stats.
P.S. I have also try to charge while on, then turn it off, charge again etc. I found some manual.

Ok I will do it

It drains because of Sony bloatware and not a very fresh battery..there is many reasons but the main is bloat and battery that is old/not calibrated properly...get the battery out wait 5 min and press power button and hold for couple of seconds WITHOUT BATTERY put it back use the phone until it shutdown itself,connect charger turn it ON and then charge for 7-8 hours.and get rid of widgets.that is all you can do without root and stock.make sure GPS and Bluetooth is turned off when not needed and 3g/WiFi.if all this don't help after couple of days of use try juicedefender maybe but its heavy app that runs all the time it will slow the phone.

Battery Drain
Try the above suggestion.
Also I suggest that you root your phone for optimize usage.
In that way you will be able to remove the bloatware correctly.
I use Setcpu profile activation. When my lockscreen is off it lowers the cpu settings.
