IP4 battery/usage issue

Throwing my hat in the ring

I haven't reset/checked the usage on my phone, but I will do that next.

However, I have noticed my battery drains at a rediculous pace. It dropped 14% in an 8 hour span over night. I made sure to close all apps, locked it...and didn't touch it for 8 hours... This morning it was 14% lower.

What the heck.

And when I actually use it, the percentage ticks off like a time bomb.

This is getting worse for me, unfortunately. Charged my phone yesterday to 100%, and then unplugged it right before going to bed. Something's definitely not right. This morning:

Did you leave Bluetooth on overnight? I see it in your screen image.

Even if he did, that shouldn't cause that.

i also noticed that his usage and stand by times are the same. how is that? said that he unplugged it before going to bed, assuming that he didn't touch it until this morning. don't the stand by and usage times should be different?

Having similar issues. My usage meter seems way off. I've used the phone for maybe an hour tops and it read 4 hrs +.

Strange...

same issue here. just like everybody say.
i did a test based on
fresh restore 4.0.1/unjailbreak/all stock app,no apps in multitask bar/4 hours total charge/restart iphone/unplugging and leave it overnight without a touch
Disable Bluetooth, enable 3G/WIFI/PUSH/NOTIFICATION/LOCATION
after 8hours43mins battery goes to 97%, seems pretty good ha.

however, after jailbreak, i find that the battery drops every couple of minutes standby, and mostly USED TIME IS PRETTY MUCH THE SAME AS STANDBY TIME.

well, that's all happed when standby, i notice that when i actually USE it, battery drop even slower than standby. let's say i can play games for about 5 hours during one single charge. this seems normal to me.
i did install the iphone case app, facebook, no car charger. i think something is wrong when standby.
