This may sound weird but I'm having an issue with my battery reading 100% for too long. I was on CM7 RC2 and then RC4 and the battery percent would drop evenly. I leave the phone on over night because I'm on call 24/7 at work and in the morning the battery would read around 93% with RC2 or RC4.
I went back to the stock rom last night because the navigation on those two RC's is a bit messed up and I noticed that my phone in the morning was still reading 100% battery.
The problem with this is, I know it's obviously not fully charged, but the green light still comes on right away when plugged in because I guess it thinks it's fully charged. Is there anyway to get an even battery drop with the stock rom?
Your battery stats are a little off, that's all. There are posts all over xda on how to recondition and recalibrate your battery. Just find a good guide and follow it, you'll be back to normal in no time.

Thanks for the info! What I could find said to charge to full, delete battery stats and then run until the phone turned off by itself and then charge to full again. I'm currently doing that now so hopefully I'll noticed a difference.
I've read that there is a possibility letting it die completely damages the battery (something about crystals forming). I usually just run it to 1% just in case the above is true, but other than that you got it. I would have told you, but I'd just state steps, this way hopefully you got a little extra info from people with more knowledge than myself.
Has anyone realized this or is it just me, every sense 3.5 that I've tried the battery indicator is incorrect.
For example, I just had 41% battery life before resetting my phone and now I have only 4%. Is it not charging the battery correctly? I also turn the phone off after it says 100% and then charge until the green led comes on but still it is either draining too fast and phone doesn't detect it until a reset or the battery isn't be charged completely because the rom thinks it's 100. I have caliibrated and erased the batterystats.bin file so many times and it's still the same. any insight on this? I have a brand new battery from htc as well.
Same problem
Constantly "calibrating" or deleting the battery stats is the exact reason this happens. You dont have to do that, regardless of what people say.
This will happen until the battery has been charged/discharged a few times and will slowly stop happening.
No issue here, got my new anker battery.. Flashed BP 2.1.5 and since then, my battery has been normal and amazing!

This. When I flash ROMs I don't really do anything in relation to the battery. I just use my phone like normal. The first day or two you might get a little more drain than usual, but after that it will be completely normal and you don't have to do anything like wipe battery stats or calibrate or run it down to 5% and charge it all the way up or whatever.
Yes, constantly resetting battery stats is bad. Should only occur right after flashing the new ROM. Ideally you'll have charged your phone to 100%, flashed the new ROM, and immediately putting it through 5 discharge/charge cycles.
My battery life was horrendous when I didn't properly calibrate the battery. Going through the process now and its lasting a significantly longer time compared to not going through the process. I'm talking about getting like 6 hours of light usage compared to like 15.
Or it could be just ARHD. I really didn't like that ROM. Anyways, I'm running Bulletproof 2.1.5 with 3.5 Sense on an Anker battery and its doing great.

I'm gonna have to disagree with you on that. My battery life was horrendous when I didn't properly calibrate the battery by going through at least 3 full discharge and charge cycles.

+ 1 my battery was shocking, im on my second full cycle currently at 2% lol and already i've noticed improvements by like 20%

I've done everything, calibrated the battery numerous times with and without wiping the batterystats.bin and it's still acting up. Say this morning I wake up, take the phone off charge at 100%, go out, and restart the phone for any reason when the phone's battery meter is at 95%, after the restart the meter will jump down to 70%.
This is with a new battery, new rom, totally wiped device, I even used the ruu to get me back to the stock rom.
Anyone have any idea what's the problem? The battery life is ****, and doesn't seem to get any better with calibration.

This is your culprit. Let it bed in a few days, and performance should stabilize.
Go through 5 full charges/discharges, uninterrupted. Yes, it's a pain in the ass, but you signed up for it when you flashed a new ROM.
Everytime you wipe your battery stats, you have to go through the 5 cycle process again. Uninterrupted.
EDIT: Had a lil too much rum and misspelled a few words. I even misspelled mispelled
Alright dude, I'm going to take you up on your word, I'll give you another update within 5 days.
This is a problem with all Sensation ROMs, even with S-On and Stock ROMs. I get a problem like this one too. If I have 60% left, and I restart the phone, it goes up to 69% and I don't know why. Also very slow charging from the original wall charger, but if I reboot when it's charging at 70-75%, when it finally boots, it says 100% charge. This must be some bug from HTC or something. :S
Hi,
Same problem (with Sense 3.0/Sence 3.5 and different ROM),but is there a fix for that?
I saw this:

The thread: http://forum.xda-developers.com/showthread.php?t=1287129 .
Probably a way to fix the issue?
Should be asked about this in the ROM thread?
Me too same bug since first day, I think it's a battery sensor fault
It's not a hardware fault...it's not a battery fault...it *may* be a ROM/kernel issue...but I suggest you give your battery a few discharge/charge cycles and you'll see it should go back to normal.
Alright so it's difficult to explain this fully but I'll try. I came across battery calibration information and I went ahead and wiped the stats. I then let it drain, charge full then drain again. Now as it was charging I decided to flash another ROM, done. So that ROM took a while to fully charge but when it did I got 13hrs of battery life out of it. Now when I charge it, pretty much it stays around 50% and wo't bump higher. Literally haven't hit higher after leaving it plugged for more than 3 hours. Anyways I'm about to flash a update of said ROM and use a different kernel that is know to be more stable. But curious if there is hope for my battery? I don't plan on wiping battery stats anymore, after further readings I see it's not worth the trouble.
I'm running virtuous Inquisition 4.0, I've cleared the battery stats a couple of times and no matter what I do when I get down to like 40 percent, the phone crashes and then when it reboots I'm at 4 percent. Sometimes it just does it if I reboot. I can't figure it out. Its really bugging me. Anything I can to to fix this?
Bump? I've been trying to calibrate the battery like I always have since Donut. Has it changed in ICS?
Turn off Power-saving mode in settings and try
Where is the power saver in this rom? I can't find it. I've also noticed the battery draining unusually quickly from screen use. I just went from 54 to 30% from 10 minutes of use. Its been on 12 hours now and I'm assuming that's an inaccurate reading but still disconcerting.
What about the classic backup, wipe and flash technique? It's worth a shot if you haven't already.
Inquisition doesn't have power saving enabled, so that isn't the cause.
Barring a corrupt ROM or firmware, as suggested above do a superwipe and reflash both first, your graph looks like a failure in the battery.
Does it get hot, or has it ever been heat damaged? I'd suggest replacing the battery, if the wipe doesn't help.
Wiping battery stats doesn't actually do anything, unfortunately. Battery readings come from the battery itself. I've noticed mine's been pretty bad lately, 15% then if I reboot it's back up to 40%. 10 minutes later, 20%.
The best you can do is charge the battery all the way, discharge it all the way, charge it back up, and hope for the best.
I don't think its ever been hot enough to get heat damaged. I mean I suppose that could be the cause. My phone hasn't been through a full.power cycle in awhile so I will try to completely charge and discharge it for the rest of this week and I'll monitor the voltage readings. Its been a bit more stable today but still not lasting as long as it has been in the past. If the charges and discharges don't fix it I will reflash the rom. Still doesn't explain why like every other morning my phone will say 80 percent or something after being plugged in all night but after a power cycle it reports 100 percent. Could that also be a symptom of a bad battery? I can probably have T-Mobile replace it. Or maybe I'll buy an expanded capacity one. First I want to try to fix this one though. I'll report back. Thanks for the help guys
This is quite ridiculous. It was at 7 percent for like 6 hours today. I never know how much battery I have left. It's not like I'm getting bad battery life because I've been on for 14 hours today with heavy use but the readings are so inaccurate.
I'm going to do a full wipe, redownload everything, reflash firmware, radio, and the rom and then once I get everything set up again, if it's still doing it I will go get a new battery, probably one of those Anker 1900mAh ones that someone told me about on the virtuous rom thread. I'm not sure if it's coincidence or not that it started happening when I updated the ROM but other people aren't having the issue (except for one or two) so I don't think it's a ROM issue, probably battery hardware.
This is what VI with the Anker battery should look like:
Damn, that's impressive. What's up with that spike halfway through though? I think I'll just buy a new battery, even if this battery isn't broken, just because my god, 22 hours with 6 hours of screen on is incredible. I don't normally have more than 2 hours of screen time in a day and my battery will only last 16 hours
The spike is where the phone was reset, the battery percentage always jumps up 10%-15% on a reboot then goes back down in a few minutes. Also, the screen on time was closer to 7hrs
I would caution that I'm getting excellent mobile signal for 98% of the day, your results will probably be lower with your signal issues - have you tried the new radio driver from Tmobile?
I thought that this was an isolated case but I just had this as well. I've got 25% then I installed something via adb and need to restart. After reboot, the meter reads 45%. Absurd really.
My signal issues are not phone related, its just where I go to school. I did install the T-Mobile radio and have had much better 3g coverage and signal where I thought it was a complete dead zone. Most of the time I just turn off data and sync during school to save battery. After I did 3 complete drains and charges I have noticed that its been more consistent in reading. Still not lasting quite as long but its not stair stepping anymore in the graph. It is a little bit but not as bad as before. I'm still thinking about getting that anker battery anyway. I'm still only getting like 16 hours with 1 to 2 hours of screen usage which I would like to extend. I have a car charger so when it does die when I'm out its not the end of the world but its still irritating.
So I've concluded its a bad battery. Its started doing it again, much worse now. It randomly just loses power several times a day, as if I took the battery out but I didn't. I also.downloaded a detailed battery graph app, I took a picture of my voltage chart throughout today and its all over the place. I'll call to get a replacement tomorrow and then I might also get the anker battery. I'm getting sick of the phone just going black in the middle of a conversation or something rather. Other sensation owners have run into this problem.also.
have you guys all updated to the lastest firmware out and newest version of the rom?
No, I'm planning on flashing that tonight though. Hopefully it just turns out to be a kernel issue and it resolves when I update. That voltage graph appalled me.
when i first start using VI i had about 8-10 hour battery life, i looked around in rom manager, saw some cm9 roms, backed up my VI, and tried the cm9. didnt like it and restored my VI backup. Now my battery life is about 18-20 hours. i dont know what happened there but it helped alot. maybe somebody else with bad battery life should try this and see if it helps.
Well, I dropped my phone, landed on a concrete floor on the corner of the phone, cracked the corner of the screen and the camera lens. But I have insurance, so I'm getting a new phone within a few weeks (it's backordered right now through asurion) and when I get the new one I plan on purchasing an anker battery to solve all of the battery life woes. Asurion offered me an HTC Amaze but it has worse battery life, it's bigger and heavier and not that much better, so I'm sticking with the sensation.
Hi! So I've been using this rom http://forum.xda-developers.com/showthread.php?t=1782009 for about 3 weeks now and I'm very happy with it but I've noticed my battery has been really really bad! Here's a screen shot and this was on a full charge :\
I replied on the thread with the screen shot but no one answered.
If anyone can help I'd really appreciate it
You need to check in better battery stats and see if your getting a wake lock. Read on google or xda how certain wakelocks can be bad. You can isolate the app causing the wake lock by using better battery stats and then fix the situation. Also could be the rom but likely it's a wakelock. Once you fix your issue, it will be much better. You can get better battery stats at the market or here on xda. Best wishes.

I'm having the same problem with the same ROM, I just installed a few hours ago.
18.18: 99%, stopped charging.
18.26: 89% battery left.
18.31: 84% battery left.
18.46: 72% battery left.
18.49: 70% battery left.
Until now I have used stock 4.0.3, and never experienced anything like this. I did barely touch my phone during these 30 minutes. It still has S-ON, could this be why?

No, S-ON/S-OFF has nothing to do with battery life. In your case though, since you said you just installed the ROM a few hours ago, you need to do about 3 full charge cycles before you start worrying about your battery life.
Drain the battery right down (not completely dead though, 10% is enough), charge to 100% and repeat a few times. Then if you are still getting bad battery life you can start looking at what is actually draining the battery.
