for the past 3 days, this is what it does after just a random reboot. This was from this morning. *A huge drop in battery life*.
Now granted, have charged it a few times just until i can get to a moment where I can charge it fully without unplugging it.
Just for my own clarification, do you see the huge drop in battery power after the sudden reboot? If so, I'm wondering if the battery isn't bad, telling the phone it doesn't have a charge, and the phone shuts down/reboots.
Was anything done to the phone prior to this problem (new ROM, new kernel, rooted, etc.) other than calibrating the battery? What were you using to calibrate?

My bad on the unclear post. Rushing, multitasking not working...lol. Yeah that's what i'm referring to. I edited the op.
Not sure why it does that. I'm using the battery calibrator from the market. I did install a new ROM a few days ago.

LOL. I flashed the Octane rom by raver. I don't have another battery to test it out, but It's happened a couple times with different roms. Usually when I calibrate, on a full charge at 4.2v, I wipe the stats about 2x's in cwm, then calibrate with the app, then unplug then plug again to boost it back to 4.2v then calibrate again. All of this just to make sure it's calibrated. may be overkill.

I hear ya. I usually do that two or three times, too. All calibration does is, like you said, wipe the stats. The reboot is weird, though, as it's followed by that sudden drop in battery. Could be the battery is faulty. I wish I had more insight to help you.

Heyy after calibrating the battery how long does it usually take to see the effects of extra battery life?
I've seen varying answers on that ranging from 1 day to a few days. A lot of calibrate after flashing a new ROM, so that might add a bit of time as the system rebuilds caches and whatnot. I would think that you would only need to do the full calibration once before starting to see the effects.
I usually do the calibration then go through letting it (almost) fully die, then do a full recharge 2 or 3 times.

Thank you very much sir. So I should just put brightness to max, connect wifi, and turn on as many apps as i can before it almost dies, then turn back to normal and charge to 100?

I don't do anything different when I let it die. I just let it happen through normal use. I guess if you wanted to accelerate it, that would work.
I'm not an expert in battery, but it looks to me like you're putting alot of stress on your battery from the constant wiping, calibrating, and letting it die. I'm not sure but i heard that letting it die too often is a bad thing. Have you tried calibrating it and just use it like normal?
Well err. I just calibrated my battery but it's still going down quickly. I lose like 5% battery in less than 10 minutes

The percentage drops but it stays at whatever that percentage is for an hour or five depending on how much I'm using my phone.
because your battery gauge is lying to you and not reporting accurately prior to reboot.

What do you use to calibrate it? Wiping the battery stats?
Check out this thread: http://forum.xda-developers.com/showthread.php?t=871051
Basically the meter is lying because keeping your phone at 100% while charged is not so good for long term life of the battery. So once you get a full charge it doesn't keep the battery full, and when you take it off the charger the meter quickly catches up to reality.
So don't worry, it's supposed to happen this way.

There are several threads explaining this but you just:
-Charge to 100% and boot into recovery
-Select advanced>wipe battery stats
-Use phone normally until battery dies and it powers off
-Charge back up to 100% (preferably while still off)
Edit- if you are running das bamf you can also clear them from the toolkit.

It will fix the issue that the OP is having of the phone dropping % drastically when they reboot. If you are talking about the phone dropping from 100 to 95% or so after you unplug, then no it won't, because that is actually a safety feature that you do not want to fix, unless of course you want to burn your phone up.

No your phone stores how long it takes to die charge etc. and when you change roms these stats obviously change and therefore wiping the stats allows the phone to really calibrate to the new rom. At least I think that's how it is.

This happens to me and it annoys me everytime it does it. I dont know why for some reason this is a recurring thing with HTC phones.
My battery drops 10-15% rather quickly when I unplug it but I believe this is actually normal with newer Li-Ion charging techniques.
Mine drops about 5% after a reboot. I reset my batteries stats today and hope that will improve my battery life, but I must say I got about 8 eight hours today with fairly heavy use and a few reboots.
Note: I searched the forum and saw nothing like my issue, if there is then I missed it and I apologize.
So here is the issue. When charging it gets to between 85-90% then immediately jumps to 100%. Have tried clearing the stats, draining, then full charge. Any suggestions on this?
How old is the battery are you charging USB or AC?

very odd, I've actually experienced the inverse. Charge would hold at like 20% and then jump to 10% in a second. Are you noticing in use there is a jump back down i.e. when you unplug, does it jump from 100% straight to 90% or does this just happen when charging. If it just happens with charging, I'd say run current widget and see how much mA is left when it makes the jump to 100% and see if the battery is actually charging correctly. In other words, if you're charging and the battery jumps from 90 to 100 and you still have like 200 mA left, something is goofy with your battery and I'd recommend a new battery or at the very least full wiping and reflashing your ROM.
If it jumps and the remaining mA is like 30 or something low, then the actual battery seems to be fine and I'd recommend a full wipe and reflash the rom you're using. In all honestly, it's probably the battery and may just be worth getting a new one.

Im not attacking you im just trying to clarify. Are you saying it jumps to 100%, meaning you see it say 100% or are you referring to the led going green at about 90%?
I'm not convinced it is a battery issue... I've only very recently rooted my phone (have had it for 11 months) and haven't had the charge indicator jump past the last 10% like it did just today.
Looking at the last 26hours of history (ICS 3.0.0 install), the initial battery discharge showed normal taper from 100-85%, however on charge it jumped from somewhere just below 90% to 100% instantaneously.
I should have taken a screenshot, but instead I wiped the battery stats and am in the initial discharge cycle still. I've had the phone 11 months and have never cleared the battery stats before.
Maybe 8 months old.

Run the battery down until the phone dies. I have had this happen to me before. When I got down to 1%, it took a really long time for the phone to die. Recharging and doing a couple of long cycles of letting the battery go down to a really low level before charging fixed it. Do not delete battery stats as it does no good.

Sounds more like a battery calibration issue than a battery issue.
Give it a bit of thought... from 90% it skips to 100% when charging. However at 1% it camps out for an hour or more before shutting off. This indicates an issue with how the charge of the battery is being measured/expressed...
Now let's think about what is happening behind the scenes. This measure of charge is "defined as the available capacity expressed as a percentage of some reference, sometimes its rated capacity but more likely its current (i.e. at the latest charge-discharge cycle) capacity but this ambiguity can lead to confusion and errors. It is not usually an absolute measure in Coulombs, kWh or Ah of the energy left in the battery which would be less confusing. "
Essentially, the way the phone is measuring the battery isn't working correctly. However, is the duration of the battery life what you would expect given your use of it?
If YES, then it's a measuring issue.
This will likely fix any battery reporting problems that occur and should be done after installing a rom, or whenever you think it is needed. It will not actually make your battery life better. It may seem like it as before resetting it may have said 1% remaining when it was really only half dead
NOTE: you must be rooted, which if you are on this forum you almost definitely are

No problem. You are right. This will not help if your battery is actually draining. It only changes what android thinks your battery level is at. this can get screwed up after a flash, depending on many factors of the rom. It also is different with every device. What it helps with is when your stats are off. for example temple run takes 60% of your battery when you play for 5 minutes and you know it isn't running, or it drains fast to 1% then lasts another 6 hours. So if you are noticing poor battery life, make sure it is really bad, not just reported wrong. I will edit the OP to say this more clear.

I think partially, but I know for a fact this process works great and isn't that hard. It resets things better from my understanding because it totally wipes stats instead of just re-calibrating some things
I just recently acquired a second OEM battery, but when I replace it when it's fully charged into the phone after the first one is depleted (~10-15% left), the battery percentage doesn't increase and stays the same. Is there any software tweak that has to be done in order to get the phone to recognize the new battery?
I'm running MIUI.us build 2.4.6 with Faux's CM7 OC Kernel.

Get your phone to 100% battery and then just play whatever you like until it completely dies. Then, plug it in to charge and dont touch it until it gets back up to 100%. That is supposed to increase the battery lasting time by 20%. It only works once...so dont do it 5 times hoping for results. This is supposed to be done when you first get the phone, but if its never been you've never done it, its worth the shot.

Let the ROM 'soak' in. It'll get better. You are probably busy messing with it figuring out all the features which is normal and makes the battery seem terrible. But overall it is pretty good.
And the post above is an old wives tale these days. It's funny to read people still recommending it.

Kinda, when you first flash with a factory reset, you don't have a battery stats file. This is another good reason to flash when your battery is 100% charged. When Senior Members here say "soak in", they are saying that the first boot all of the system apk (application packages) are cached to /cache. Doing too much while these apps are being cached screws up the statistics of the battery stats. If I really want good battery life, I totally wipe, and let the phone sit for 10-15 minutes. I leave usb plugged in till it's 100%, then pull the usb and use the phone until it totally dies.
By this time, the day is over and it needs to be charged anyways. I plug it into the charger before bed and let it charge up all the way with nothing running (no wifi, no bt, no background apps running).
After that charge, battery life seems soo much better. ymmv. it would be good to know if that works for you too.
Otherwise, everyone uses their phone differently, and some people install stupid apps that have intensive background services running that eat batteries, then complain about the rom sucking instead of introspecting about how they use their phone.

Just to clarify - battery stats file have nothing to do with battery performance and the battery stat file "is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point)." Google Engineer Dianne Hackborn
ahh ok thanks guys ill do what you guys said and see if it helps
you can also install one of the battery saver apps on the market, like juice defender or similar. They will typically help and some can control how often background services are allowed to collect data.

These arent as helpful as they use to be. I have seen and challenged people to run with and without and the added battery life is either very minimal or actually worse with these apps.
Battery saver apps where created when android was very young and had bad management of the battery power. The way it works now it should lower the power to the radios low enough to save battery but not completely shut off the radios. Shutting them off will actually harm battery life because it takes so much more power to turn them on and off repeatedly then to let them idle.
no i think it was more designed for froyo and gb because if you try those battery savers in froyo or gb you can see it works and battery last long but if you test it in ics or jb (i have test juice defender with jb in the sgs3) and what i can see its that sometimes it lags (not always just when you like two or three apps open which for me in the sgs3 was weird) and data sometimes hangs i mean it doesn't load pages

The biggest thing is people dont realize how much power is used to start and stop things. Letting them idle will use battery but not nearly as much if you start and stop many times a day. Now at night if you want to turn off those things then yeah go for it. But if you are a frequent phone checker then starting and stopping them everytime will chew through the battery.
A good example is this, its summertime go outside and look at your electric meter when the ac first turns on. It will spin reeal fast for a minute or so while the system gets everything going then it will slow down. This same thing applies to your phone and its radios. Each time you shut it off it has to go through a process so you dont get corrupted data. And when you turn it on it has to use a lot of battery to make sure things dont get messed up and get to the proper operating form.
So any app that shuts off the radios manually and such will end up costing you battery if you are a power user.
If you can follow the steps exactly as i wrote them, then install the team FAH-Q kernel found in the dev section...

I put FAH-Q kernal on AOKP and it seemed to help a bit. I was using systempanel and it said facebook was sucking cpu at night while the phone was resting... so i took off facebook for the moment to see if any other apps/processes could be causing a drain.
side note:
I spend 15-20 min in the morning going through stuff on my phone. Then I will listen to music in the car on my way to work 35 min. My phone will be at 80% by the time i walk in to work. I check things during the work day once and a while and by 2pm I will be around 40%. leaving work I will have 35-30% .... ok i'll just quit now and say running 12hrs i will have about 15% left. I think I am an average phone user. not sure how much everyone else uses theirs.

Music soaks up a lot of battery as well as display, data, and sync. You can try turning off sync and data when you don't need them. But it sounds like you are doing better. I am still concerned with what else you have running in the background though... however, 12-16 hours isn't bad at all...

.... If I really want good battery life, I totally wipe, and let the phone sit for 10-15 minutes. I leave usb plugged in till it's 100%, then pull the usb and use the phone until it totally dies.

What do you mean by totally wipe? do you mean go into recovery to wipe data, cache, and davlik cache? then restore after the battery is fully charged?

Yes, as well as /system/ and at least .android_secure on your microSD
I would recommend against fully discharging your battery as a matter of course. While this might have been useful in the days of NiCads, deep discharges and heat are the Kryptonite of LiIon batteries.
