Why is my battery dropping like 5% when I reboot it? The second time I rebooted it it didn't do that.

I've noticed that on all my phones. Gets worse if you reboot with less charge. The way I think it was explained to me was; the phone uses more battery to boot and at lower charges it has to take more from the battery to boot. Why it happens sporadically like that I have no idea.

This is correct. It's like starting your car, more energy is needed to get it running than it is to maintain. When you reboot your phone, it has to do a whole bunch of thing such as start apps, find and connect to signal, mount sd, start launcher, etc etc... This is very battery intensive.

Yes this is odd. Hope it gets figured out

I'm gonna take a wild guess and say that most likely the battery is either getting weak or isn't calibrated correctly. And just whatever is using that last little bit of energy, which, in your case, will always be the android os, is going to show using the largest percent of the battery.

Sounds like your battery went bad perhaps?

Dude, you're doing it wrong...
froyo tastes better than gingerbread.
I noticed a small upward movement in battery level graph under battery usage screen on my phone. Yesterday too I noticed the same, but ignored it. But today, I'm totally perplexed on the increase.
Am attaching a screenshot for the same. You can notice the little upward movement towards the later part in the graph.
Any explanation would be well appreciated

This is the most obvious answer of all of the stupid questions on here... ROMs rarely report battery level perfectly.

I know kind sir. But this has been happening only y'day n today, n I've been on this rom since abt a week now. Never noticed this on any of my earlier phones or roms. Posted this to see if anyone else too observed the same.
And let me add to it: I noticed bumps like this on a restart. Not while the phone was still on.

If on a restart - the fuel gauge chip probably got reset when you restarted.
I'm not sure if restarting the phone resets the chip. I'm 100% positive a battery pull will.

I did a battery pull today. Gotta see if that helps.
Honestly that bump is incredibly minor - I wouldn't worry about it at all.
My battery just drained 50% from half an hour of texting. My screen is on auto brightness and I'm inside. I rebooted and it's still draining rapidly. Should I exchange it?
It sounds to me like you have a rouge app going wild. Download "system tuner" from the play store, open it and click on task manager and view what apps are running and view how much each one is taxing your CPU. Hope you find your answer...

Agreed, I had a phone that would die within hours, deep down I found some odd app and that was swallowing the battery, disabled it and everything was fine.
I killed everything except for Messages in the stock Task Manager and it continued to drain like crazy.

How can you solve it?
Don't let your battery get below 10%?
The system is designed so that when the battery gets too low it turns off a lot of stuff so that the device will last for longer to do what it was actually made for - be a phone.

Indeed often the cpu is slowed down to which would cause lag.
But yes the best thing to stop it would be to keep your phone charged

I removed the general bloat that this phone comes with, as well as the carrieriq ages ago. For the past few weeks I've been experiencing great battery life and struggle to drain it since I primarily am a casual user with no more than 2-3 hours of screen on time. However, today, I looked at my phone and saw that the battery had drained a lot quicker than normal - I had to charge it a few hours ago. According to wakelock detector, carrieriq appears to be draining it.
What gives?

Did you use a carrierIQ checker? Voodoo is often recommended. It will let you know if there is any files left on your phone

Just installed it and got this:
I'm not sure those consists of files I could just blithely delete without getting boot errors and what not. Is there anything I should do? My battery life is draining faster than normal and if this keeps up, I'm just going to sell this phone and get an international version.

Unless you specifically removed CarrierIQ when debloating, it's there. To remove it, check here
