Does anyone have a link for the thread that discussed the correct way to wipe battery stats when upgrading to a new Rom? I remember it went something like drain dead, charge to full, drain dead again then charge to full and wipe stats. I can't remember the complete process. Thanks for the help.

I've seen a couple different threads on that here, one saying discharge fully then charge while powered off, and the other saying to do a full charge "conditioning cycle". I did the latter and it seems to have made a difference.
Here's what I did:
Charge the phone fully with it powered on
When fully charged, disconnect cable
After green LED goes off, power the phone off
When phone is fully powered off, reconnect cable, amber charging light should be on
When LED goes green, disconnect cable
Repeat previous two steps 10 times
After 10th cycle, boot into recovery and wipe battery stats.
I am using Amon Ra recovery which has the wipe battery stats option under the Wipe option. I never did this when I had Clockwork recovery installed, so I don't know if the option is in the same place.
Being an electrical engineer, I find this business of battery conditioning interesting, along with the Ni-Cd "memory" vs. Li-Ion "no memory" issue. If anyone has found a decent physics-based explanation as to why these things do or do not have any basis in fact, I'd appreciate a link. Yes, I'm too lazy to Google it at the moment.
Hmm, I may have to look into this again. I charged my phone all night (powered off) and unplugged it this morning. I did nothing with it this morning but turn it on and look at it, then put it in standby (quick press of power button). It lost 16% of charge in less than 2 hours!
I'm running BS1.2 with the Baked1 (low voltage/best battery) kernel.
Damn, just installed System Panel and found that my CPU is at 100% constantly!
I'm trying this now. The longest I've pushed my battery was 22 hours... and that was with 39 minutes of screen on time, lol. In standby almost the entire 22 hours....
Ok, I believe my issue was related to a camcorder problem, my CPU usage has dropped back to normal levels after fixing that separate problem. After my battery recharges fully I will see what happens with the charge.
the other methods to do "calibrate your battery" (which isnt really calibrating the battery but the battery stats of the phone so it can accuratly judge when it stops and starts charging)
1) charge the phone to full
2) unplug and use phone till it shuts off from no battery (do not plug in until it shuts off)
3) charge phone to full again with out unplugging till 100% (check under about phone > battery it shoudl say full charge there)
this should reset the battery stats.
the last method is one from HTC
1)Charge the phone for 8 hours uninterupted with power on
2) turn off the phone and charge for an additional hour
3) turn ont he phone unplug it and let it sit for 2 minutes then plug it in for an additional hour.
all 3 methods listed should help. I personally dont like the x10 method because it has the potential and basically over charges the battery to make sure it is acctually at a full charge. It is much faster then the other 2 methods though so to each there own.
Dont waste your time on...
plug/unplug 10 times. It really doesn't recal the battery.
the unplug/plug 10 times.
1. Phone on...charge until green light comes on. Immediately unplug and turn phone off.
2. Plug phone back in until green light comes on again. Immediately boot into Recovery and wipe battery stats.
3. Use the phone on battery until dies.
4. recharge phone to 100%
You are good to go!
If I tether during the day (5+ hours) a lot, is it bad on my battery? Isn't that like a constant charge or does once the LED turn green it stops trying to charge?
Thanks.

the evo doesnt do a trickle charge so when the light turns green it stops, this is why you will almost always drop 1-5% battery rather quickly.
Are you sure? My light has been green for a while, and my phone battery status says 'Full'.

There's a lot of confusion over how the battery / charging circuit works and how it reports. My advice is to just charge until it's green and full, then unplug it. If you leave it plugged in all night, unplug it for 10 mins in the morning, then plug it back in to top off.
That doesn't really help me SilverZero, my question is only if leaving it tethered (which means connected to USB) is bad for my battery.
Well on mine i would check it every once in awhile and i would see that once it get downs to under 90% that it would charge again till it recognized that it was full again. So based on that i dont think you should have to worry about it. It seems to only draw the charge when needed. I also leave mine plugged in alot when im home so its good to go when i leave and havent noticed a loss of battery life at all.
You guys don't want the charger to trickle charge. Li-Ion does not accept overcharge, even 0.01C (15 mA on the stock Evo battery) will cause it to vent and probably combust.
So does "calibrating the battery" calibrate the phone or the actual battery?
I ask because I have 3 spare batteries, wondering if I have to do this for each of them??? They are all standard size, one of them OEM
Hey everyone, I am having some trouble with my rooted phone. Prior to rooting the phone, I had no battery life issues. Right after Christmas, I had a little bit of time and I rooted my phone for tethering, mostly. I used the root listed on this website at the time (I couldn't use unrevoked because I had just done the OTA update to the software) and installed no further changes. Since then, I can get about 8 hours before the battery is well below 50%. This is without making any phone calls or using the internet, and maybe a few texts. I have resorted to turning off the connection to the internet, and this preserves my battery and allows me to make some calls without absolutely killing my battery. When I unplug, I can almost watch the battery life drain. I will be at 90% by the time my 15 minute drive to work is done. I have tried changing chargers, buying a new battery, and nothing works other than shutting off the connection to the internet. When I look at what has been using the battery, I not no time where I did not have a cell connection, and all the battery usage is idle and connection to network time. Any and all help is appreciated. Thanks!
Wow, your situation seems very strange. Are you running a custom ROM or kernel? Have you tried using spare parts to see what is actually consuming your battery? Perhaps, you can try wiping everything from the phone and installing the stock ROM or other custom ROM of your choice. Please keep us posted, good luck
Recalibrate the battery. I would link you but kinda hard to do so. Just search the forums for it.

What Rom are u using?
That is happening to me too. After I first rooted the battery life was good better than before. I had been using vaelpak, then a about last week my battery started to drain so fast. I would take it off the charger and do a little texting or check my emails. Shower or what not than I pick up my phone and its like 92% already. Thinking maybe I have too many apps so I deleted some and then forced stopped a few and I forgot what else and that day my battery stayed on 60%(thats what it was on when I took it off the charger before I left) for about a good two hours and i was listening to music and the internet and text and all that. Kinda scared me because I thought I messed something up, but the battery lasted longer that day. Then the next day back to the same old same old. Last night I flashed warm twopointtwo and was charging my evo last night but I put it under the pillows by accident and woke up this morning the phone was burning up and flashing red and green at the same time and it had stopped charging. I took the battery out and let it cool for a few hours. now its charged back up. I wanna see if the battery improves with warm but I think I'm going to flash another ROM but this one is too pixeled and its killing my eyes So upset. but let me know if you fix your battery problem
hmmmm....maybe....

I'm having similar problems, though not as dramatic - mybattery life only lasts about a third of what it used to. I am running 2.2 RLS 5 witht the htc stock #15 kernel. What I am trying to do is hunt down a decent kernel that is compatable with RLS 5. I have found a few - but I am still in the process of researching information about the issue.

After I try this out - I might or might not switch my kernel - But I wll say this - I had absolutly awesome battery life when I was running HTC stock #17 - you might could look into flashing that instead of what you are running now (flash it just like you would a ROM) - you can find it here
hope this helps out a little bit - but in reality - getting your battery the way you like it is really more of a trial and error type procedure...good luck
Ah, welcome to an elite club...right. I rooted my 003 Evo last summer after getting it shipped to me. From then until mid-november of last year, I got great battery life. Before the switch flipped in November, I could leave it sit overnight and i'd use 1-1.5% charge per hour, so worst case after 8-hours sleeping with no use I'd be at 86-88% charge.
Then suddenly as it a switch had been flipped, I started getting horrible battery life. The ROM didn't matter, settings mattered little, it just sucks no matter what I do. If I unplug it at 6:00 AM and leave it completely unused until 2:00-3:00PM that afternoon, the stock battery is at 31-35%. The awake time will be under an hour, and every utility that I use reports nothing out of the ordinary.
I bought a 3500 mAh battery and its better of course, but gets me nowhere near the use what the stock battery used to provide. I unrooted back to stock with the same results so I rooted again of course. Might try flashing back to the 1.77 PRI and NV. Some folks are getting better battery life with those, but that may only be related to sleep issues which my phone doesn't appear to have. It may prove to be a waste of time, but I have to keep trying.
Good luck all of the club members! Thank you for your time.

Tried the middle one from HTC as well... we will see how it goes. Just in the time I have been typing this message (about 2 minutes), my battery has gone from 91 to 88%.
Also forgot to add that I have been out of town every week for the last two months and noticed that the HTC weather thing on the startup screen hasn't been switching to my current location. Always shows my hometown, even if I force an update.
I think I figured out the problem... ran into several threads discussing PRI incompatibility with HTC kernel #15. Flashed back to 1.77 and doing much better. Didn't mess with the NV. We will see how it does for the rest of the day.
Problem:
I have been reading as many posts as possible but I haven't come across my exact situation. I apologize if this is posted elsewhere.
I am running a rooted Dinc using CyanogenMod 7.0.3. If I charge the phone while it's powered on, the amber led turns green as soon as the battery indicator hits 100%. However, recently I've noticed that if the battery is close to being full, say 90%, and i power it off to charge it, it actually takes longer for the amber led to turn green. It might take 20-30 minutes longer.
I've also noticed the amber light turn green when the indicator only showed 92%. In trying something different I also noticed that if I charge the phone while it's powered on, then turn the phone off, the led goes amber and takes another 20 minutes to turn green again (I might be accidentally bump charging in this example but I'm not sure).
Attempted Solution:
I've read that a battery recalibration might help. I tried one method that requires the battery to be pulled after a full charge, but my phone won't boot while plugged into the wall if there's no battery. Then I tried booting into recovery, where I found an option to reset the battery stats... which I just did about 5 minutes ago.
I'm going to see how things go tomorrow, but is this normal? Has anyone else experienced these things? Thanks.

The kernel and the hardware charge it in different ways. That's why there are differences. DInc is famous for ending charging before the battery reads full. There's already a thread on that. there's not much point in getting hung up on how that thing charges. Be glad yours isn't like mine; a battery that discharges faster than it charges. Seriously.

Before I had a fast charge kernel (thanks Chad!) Using GPS with the stock VZW car charger, my battery would go down while it was on the charger!
Sent from my ADR6300 using XDA App
On AOSP roms, the LED will turn green at 90% and charge slower from 90%-100%. Perfectly normal, and I think on any rom it will charge slowly from 90%-100% to protect the battery.
The battery will charge further when you turn the phone off, what you described is what's known as bump charging. If you do this, you should notice a slower drop from 100%-90% than usual, because the battery is charged to a "true" 100%. When the phone is on and charging (above 90%), it simply keeps the battery above 90% even if it says it's fully charged, and this is why the inc is notorious for the quick 100%-90% drop.
If you do a bump charge and then clear the battery stats and use the battery calibration app will you need to bump charge again or will it know what the true 100% capacity is and keep the droid lasting longer. Not noticing much of a diffrence when i went from 1300 battery to a 1500. May get a bigger batter that'll fit the stock battery door cause I'm trying to get the best battery life i can get.
Thanks guys, I appreciate the help. I think something else that has thrown me off is that before I rooted the phone I wasn't able to see the actual battery percentage in numbers... all I could see was the battery icon. Things are now making more sense.
After recalibrating my battery I bump charged the other day and I was able to get almost 2 days out of my phone on light usage. Without bumping, I was able to end my day yesterday at 50% under my normal usage. Which is a noticeable improvement. Normally I end the day with about 10-20%. The big test will be once I go back to work next week. The cell reception is real spotty in my classroom, which I know makes the cell radio work harder.
Thanks again.
I found a lot of answers I was having about battery charging in this thread:
Your battery gauge is lying to you (and it's not such a bad thing)
I’m having battery charging problems with my HTC One XT, which seems to be a common problem for the HTC One X. The main problem is the phone seems to have trouble getting fully charged to 100% and hovers around the 75% mark.
For example, I charged my phone (while on) overnight (over 11hrs+) when the battery status was at 20%. When I checked my phone in the morning, the battery status was near 0%. So I disconnected the charger and the phone turned off. I turned on the phone and the battery status was 75%. Also when I leave the phone charging while it’s on, it’s seems to be discharging rather than charging and the battery status seems to get lower.
After some searching around the forums etc, here’s what I tried:
1. Disable Fast Boot via power settings
2. Set processor limit to at most 4.
3. Manual screen brightness
4. All Wi-Fi/Bluetooth connections are off.
5. Restarted the phone a few times.
My phone is rooted with X-Revolution ROM and is brand new and is only a few days old. What could be the problem?
So fellow members, please help me solve this annoying issue.
So my phone kept discharging when I kept trying to charge it with the supplied charger. It literally went down to 0% and the phone was empty.
So I decided to use my old charger from my Incredible S and my phone is back to 100% now after a few hrs of charging.
Seems to be working fine for now. Could be an faulty charger I assume.
I did read through a bunch of battery issue threads. But I think mine is unique. At least I didn't see anything.
When used normally, battery life seems to be typical. With moderate usage, I get about 6-8 hours or so.
However, I switch phones alot (currently building a new website, including mobile) so I have been using my One X with no sim card. Airplane mode with wifi on. Doing so, after about an hour or so of only using the phone a minute here and a minute there (just to test my website changes) the phone will use about 30-40% of its battery.
But the worst thing is; when I am done, I power off the phone. Most recently it had 60% charge when I shut it down on Thursday. Today I went to power it on, and the battery was dead. To the point it wouldn't even power on when I plugged it in. It took about 20 minutes before it had enough charge to power on. I checked usage, and Google Services is 72%, Android OS 8%, Chrome 5%, Internet 4%, HTC Sense 1%, Android System 1%.
When I charge it, it will only charge as USB. Even using the usb cable and plug that came with it, it won't charge as AC like my Nexus would. Which isn't a huge deal, but it takes most of the day for it to fully charge.
I was just wondering if the above is all normal. I bought it used. It's a stock AT&T phone. No rooting or customization. OS is up to date.
