Incorrect battery reporting w/ Sense 3.5

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:
Batt Jumping hopefully solved (Beta) = Done

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.

Annoying battery issue

Hi!
When my phone (a normal secretion) shows 9% left of battery, it just dies, and wont boot before it has charged in 15-20 minutes.
It happens on both Anker og EVO 3D battery. I'm currently running the newest ARHD with faux kernel.
I have deleted batterystats when its fully charged and currentwidget shows 0 ma.
Any advises? Thanks!

Well I can tell you that deleting battery stats does nothing. Other than that, no idea.

Hey man I just made a similar thread. I'm using the latest ARHD Rom as well and was having the same issue regardless of which kernel I used. Mine will die at any battery percentage randomly and refuse to boot for awhile. Then ill get a successful boot and it will be done for awhile butthen start happening again. Battery percentage will be jumping everywhere. The only time its fine is when the charger is plugged in.
Sorry for typos on my phone now.

Tnx for answer. I had the same issue with random reboots on the Anker, bit not with the EVO 3D battery, just at that 9%. Im so satisfied with the rom/kernel, so i hate to try another rom.
Im also typing from my phone, its nice!

Strange battery stats.

Hi, my phone battery keeps messing up. I have done a battery calibration but it still seems to mess up.
The main problem is that the battery runs out, 10 mins later I have like 3 percent battery, then that runs out so I start to charge it, it charges up to around 20 percent then it jumps to around 60 percent.
By the way I have terrible battery life too - maybe 1 to 2 hours of use before running out.
Edit - I didn't say this but I am on albinoman887's cm10.1 rom.

I'm facing a similar issue, and changing Kernels doesn't seem to help either.
Things have gotten slightly better now in today's build. If updating doesn't help then you should try staying in an older build, the last where the issue was not present.

I don't think its the ROM's issue. Even by itself, after reboot I gain a few % of battery but those deplete quickly.
And then while charging. I restart, from 20% to 60% is possible too. So its not recommended restarting while charging.
Full charge then calculate drain pattern.

I have similar problems. My phone also shuts down very often. When I turn it on again it shows strange readings like 0%, 11% etc. If I reboot my phone it might either stick with the percentage it showed before, not boot at all, or jump back to 80% or so. However, it never takes long before it shuts down again. Even happens sometimes when using my charger...
Chances of my phone shutting down instantly are nearly at a 100% when using the flash while taking a picture.
I don't know what to think in terms of whether or not this is a software or hardware issue as many other people have similar problems, all on different roms and kernels.
Currently I am on:
Firmware build: 3.33
Kernel: Sultan Kernel r21
Rom: JBMIUIv4.1 #3.3.1

about battery percentange when chraging it's a commonn htc issue
i have the same too
no one has found a solution for it yet

Do you all get bad battery life too? Because I don't seem to get a very long battery life.

No. The battery life on Albino's builds has been nothing short of fantastic for most. You might consider replacing your battery if it's the original stock one. It's bound to be wearing out by now.

I have just bought an anker battery so I will see how it fairs vs he original battery.

R: Strange battery stats.
I believe its something that occasionally happens when u change a rom and kernel. I remember theres somewhere where u can reset battery stats....i think in clockwork...

In fact, kernel and ROM do affect battery life, search for what fits your cell phone the best.
I get amazing battery life on ViperS 1.6.3 and the latest Faux + Yank555's kernel besides TurboBoost MOD... These can make up a great combination

I dont think they affected the rom so much as to ruin the battery or drain it faster. Charge the battery and reset stats 90% i bet it works.

I have had this problem through numerous roms so i have put it down to the phone and not the software.

R: Strange battery stats.
It can happen at any point if u ever flashed a not-so-secure or old rom.
Once the battery percentages, for any reason, get corrupted, theyre gonna stick to being corrupted no matter how many flashes u try.
Really its not that difficult u just have to press a button (i believe, as i said, in clockwork but im not sure) and all that will happen is when phone reboots battery will get reanalyzed and resynced, nothing else gets modified. might save ur day.

I do this every time I flash a new rom anyway, but thanks for the suggestion.

You are describing 'battery calibration'. Its complete urban legend hogwash. It does absolutely nothing.
Wiping the battery stats has no effect whatsoever on battery performance. Those stats get wiped every time you charge the phone to 100%.
However, you can improve the battery reporting by charging to 100%, then draining all the way to 0%, then charging all the way back to 100% again without rebooting (other than after it shuts off at 0%). This is not calibration. Its just running the battery through a full charge and discharge cycle. This helps to stabilize how the draining is reported. It does nothing to actually make the battery last longer.

Then please explain how I can drain my battery to 0% if my phone shuts off every minute. As long as I keep the charger plugged in, my phone will function like it should. However, as soon as the charger gets disconnected, it's only a matter of minutes before the screen goes blank and my phone shuts itself off without notice. Then when I reboot, chances are that either 1) it won't even boot and shut itself down at the splash screen 2) it's gonna give me a strange battery reading and shut itself off again after 10 seconds of activity. So how am I supposed to drain my battery if I can't even get it to drain, because it constantly shuts itself off?

The stock battery that comes with the Sensation is known to have this problem. I experienced this problem quite often before I was rooted; a new 1900mAh battery remedied the issue. Here is proof that this isn't software related: after becoming extremely frustrated with the lags and random reboots of my recently ICS-updated Sensation, I decided to do a factory reset. The phone restarted normally with all data wiped and everything seemed like normal again. So I was just sitting there happily with my phone at 50% battery. I decided to open the browser to go and browse the web, and the phone was quite goo- BOOM! RANDOM REBOOT! After my phone finished rebooting, it was at 4% battery!
Moral of the story: HTC doesn't know how to make batteries. Buy a third party battery like Anker.

battery life varies from phone to phone, kernel to kernel and rom to rom. but your battery behavior sounds exceptional.
Like stated previously, wiping battery stats in recovery (Battery Calibaration does exactly the same on rooted phones) has never proved me to be efficient. Random shutdowns occur when the phone isn't recieving enough juice from the battery, the demand in voltage will exceed the CPU's capacity and the phone shuts down to prevent damage.
here's something you can try and it worked for me. I used to have random shutdowns and poor battery life aswell.
Wedge a piece of paper, like 0,5-1mm thick, between the upper right corner of your battery, and the battery housing. This way the battery will be presses firmly against the 4 contact pins. Also make sure the contacts are clean.
maybe it's just a battery issue. What does the battery info section say about the condition of the battery?

My anker battery arrived 2 to 3 days ago and it seems to have stopped all problems with the battery.
Thanks for all the suggestions though. I will refer back to this thread if any other problems arise.

Battery draining really quickly, even when idle, SENSATION CYANOGENMOD 10.1

Hi everyone, at the weekend I installed Cyanogenmod 9 on my sensation, after experiencing a bit of trouble with it draining my battery super quick I tried charging it and then discharging it fully but the problems persisted. I was told to try this ROM (http://forum.xda-developers.com/showthread.php?t=2115520), I installed it (before doing so I wiped absolutely everything, cleared caches and wiped my SD card to be safe too), and still the problem persists. The battery drains really quickly, and even when it's supposedly idle and locked, I checked after about 10 minutes it had managed to loose about 3% battery. So I downloaded a battery stats app and let it run for a few hours, took a few screenshots (http://imgur.com/VwBtGct,BVhNjyI,mDrzMS7,v740lzH,pdXS238#0 click through the images near the top) and nothing really out of the ordinary. Is there something im missing? Or anything I can try? Or is there a chance that after a few charges and discharges the battery will be alright (it's an anker 1900mAh and I was used to going right from dawn till dusk with tonnes of battery left with the stock Sense OS).
Thanks! any help is appreciated

Battery issue

I recently received a used nexus s 4g. I have installed slimbean and a custom kernel to enable voodoo sound. I have been having a weird battery issue. I can charge the phone overnight at which point the phone says it is fully charged. If I turn the phone off for a few hrs when I turn it back on the battery says it is only ~25% charged. This incorrect since I can still get full battery use out of the phone after this. I wouldn't worry but I am using setcpu and have profiles enabled and they are based on battery percentage. Any help is appreciated.
Slimbean ROM slim-4.2.2.build.8-OFFICIAL
Air Kernel
Have also tried matr1x kernel with same issue
Also tried a new battery.

Hi There,
Probably there might have been a lot of battery stats accumilated in your phone try to wipe battery stats but first charge your phone to 100% then wipe Battery Stats in CWM. Aslo clean the terminals of the battery. And flash a custom kernel which maximizes battery life in Nexus S
