Battery drain when rebooting - HTC Sensation

So just yesterday I encountered this problem and i would be grateful if someone would be able to help me. When I reboot my sensation I end up with around 20% less juice. Any ideas? It doesn't happen all the time, just the first time after recharging. I'm running CM 7.1.

I'm not sure but it may be connected to the calibration process. Did you calibrate the battery?

Have the same.
Reboot it again and its back to normal.
I guess its a wrong callibration or a bad charge or something like that

I think I did. I used the Battery Calibration app.

Problems with the battery

Hello all,
I have been having a situation with my phone where while I am using the phone and the battery reaches about 80 - 75% the phone just dies without even shutting down, and when I turn it back on the battery is at something like 1%. Even more strangely, if I turn it off and wait for like an hour then reboot, it is back at 80%. I have calibrated the battery, so I am sure it is not a calibration issue. Also, this has been happening on every rom that I use. I had a Vibrant but traded with my father but I have the battery from the Vibrant even though they are the same.
Thanks in advance.
EDIT: I have discovered this is due to the battery itself and not a calibration error. I am using a new one now with no problems. Thank you very much for the suggestions though.
Gingerbread or Froyo?

I am using gingerbread 2.3.5
It is newest valhala with a voodoo kI3 kernel.
Go to recovery and go to advanced/wipe battery stats and fix permissions

You need to calibrate your battery. download the battery calibration app by nema from the market. Charge your phone to as close to 4200mv as you can. Calibrate in the app. unplug phone immediately. Let it die completely. Charge it back up with no break

Thanks but I have tried this before posting. I did not let it run empty though, so I will try that.

The whole point is to let it run empty after clearing the stats when the phone is full...

My phone will read 99% charged but my phones widget will read
100%.
Is there something that I need to do or is it just because of the custom Rom/

Hi after flashing every Rom charge to 100% then plugged in go to recovery wipe battery stats, unplug. This should help clear up the confusion. Possibly old stats are corrupting the percentage. I do this with EVERY Rom I flash! It really helps!
Best of luck hope I helped.

What above poster said or either way you can use battery calibration from the market there is a few apps out there but they all work good..

Hi,
Wiping battery stats is a MYTH
Sometimes getting to 100% just takes a while.
Be patient.
Let the battery charge fully + 15 minutes.
Do this for several cycles,and it will settle down.
Or just change Your Kernel

Phone shutdown unexpectedly

Please guys I need help. My phone was running smoothly with no issues before. Then I finished surfing the net after that the phone keeps on shutting down at a setting interval when am in the middle something or not. I have done some things I know to bring it back to its proper working conditions but still, no improvement and I have restored to the original backup system software because I was running on custom rom before the incident and it still happening.

Tried another battery, ejecting your sd and SIM cards or if the shut down happens with a charger plugged in? If yes then do a super wipe, flash fresh firmware and ROM then test before restoring anything, check all MD5 before flashing.
If it still shuts down with fresh everything then maybe a hardware fault, return to stock and do a warranty repair.

Try THIS fix. Maybe your battery is loose
I have not tried a new battery I will do that and see what happens next. Because I also suspect the battery, I was having 87% battery life when the phone shutdown unexpectedly and I powered it on again the battery became 13%, I think the battery is the culprit here. I will try what you said and see.

Strange of the battery to go down so fast. Yes you should probably try another battery
Ad he said try different battery . My mugen battery was behaving like that then my device turned black and I couldn't boot, no charge light was detected! I switched batteries back to Anker now my device is running fine. Strange because the mugen was a new battery but sometimes this happens. So yes definitely try another battery.

Yeah!!! You guys are great I appreciate the ideas you guys contributed. What I did is I scratch the surface of the battery and attached a small piece of paper on the back of the battery to enable it stay firmly in the housing. Since then it has not shut down and the battery is even lasting longer now. I am still observing it and I will bring a feedback later.

Should I say BYE to this battery?

Hi, its been a year since I am in this rooting process and changing Roms and kernels but for few days i'm noticing an issue not only on VIPER 1.60 (currently using it) but also on others. My phone takes long time to charge and the battery bar is all messed up. Shows different readings before and after restart and all the battery just drains with speed of light? Need advice, thanks
Sent from my HTC Sensation Z710e using xda premium
As a last step before getting a new battery, probably you could try placing a paper card or credit card between the battery and the back cover to see if there is an issue with battery positioning. I resolved similar issue with my phone this way.
If your battery is draining that fast, yes I would definitely look into buying another. My stock battery was awful, finally I broke down and got another, I'm very glad I did! It makes a big difference to have a good extended life battery! If I we're you, yes I would by another battery. Hope this is helpful. Best wishes.

Sometimes the problm is with the machine inside the phone. If that machine is malfunctioning then it will also make your new battry dead.
So confirm it first.

I had a similar issue, my battery wouldn't charge past 80%. I tried wiping my battery stats and everything, try the battery in a different phone if you can. I bought the 1900 MHA Anker on amazon. I get 6-12 hours more out of this battery than I did with my stock because it was so beat. Good Luck
Thanks everyone I will get new one ASAP and I think hardware except battery is sound

Charge your battery to 100%, reboot to recovery, wipe battery stats, and reboot.
Tried 100 of times but I think no luck I have been doing this for so many ROMs

[Q] battery for htc inspire 4g

wierd situation i am in. my battery charges to 100 %....i tinker with it and little by little my battery drains to about 90%...heres the thing though....i reboot the inspire and the battery says its up to 97 again. after some usage, it will get to 56 %....i tinker some more, then reboot it. then it is back to 78 %. i have done the battery calibration, manually wiping battery stats through recovery. why is my inspire giving me false battery stats. even when im at 10 %, my cell stays on forever. its like the device is not recognizing its true charge. anybody have any ideas on why this is doing that? any feedback would be appreciated. oh, btw, this phone has done this even when i was pure stock before root. i tried installing a new battery, but that does the same thing.
plz help
What ROM?
Have you let the battery discharge fully after calibrating?

Have you tried a different OS or version?

You haven't answered what ROM you're using. Also you haven't confirmed whether you took the battery to a full discharge after calibrating it.
Calibration is a myth. What ROM? Which new battery?

Maybe it's the port..it sometimes takes a few before the phone aactually starts to charge.
