Battery drain when rebooting

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.

Q: Battery gives wrong reading

I'm facing some battery problems at the moment. My battery drains extremely fast that it won't last past half a day. When I charge it it charges extremely fast from 0-50%, then slows down. When I restart the phone at around 60% when charging, the phone becomes fully charged.. anyway to solve this issue ?

Don't worry, incorrect battery information is common after flashing a new ROM.
What you need to do is download a Battery Calibration app from the Play Store.
I recommend this one. Charge your phone to 100% and calibrate.

It can also be the first signs of your battery beginning to die.

Hey thanks.. but ummm that fix is for the random shutdowns?
My problem now is wrong reading of the battery, i don't experience any random shutdowns at all..
So is this also relevant?

Random shut downs often occur due to over heating of the battery.
I guess if you aren't experiencing any of that, you don't have any problems with battery temperature.
How old is the battery? And how suddenly has the problem come up?

I run into this problem many times.
But very simple solution if there's nothing wrong with battery or phone.
1.reboot into recovery.
2. Wipe battery stats under advanced.
3. Let your phone completely die on battery. Turn it back on couple of time and let it die.
4. Charge your phone to 100% + 10-15 extra mins.
5. Reboot into recovery and clear battery stats again.

I do something like this, but without all the extra hassle. There is an app called Battery Calibration, it shows you a read of your batteries mV and it does the same thing as the above, wipes battery stats.
I use it to check my mV, which with an anker 1900 the max mV is 4203. I keep my phone on charge once it hits 100%, then allow it to drop down to 99%, unplug it and plug it back in, it takes several times doing this, but once my battery % being 100 and my max mV (4200), match, I wipe my battery stats (Hit battery calibration.)
One thing I have noticed with ALL ICS ROMs is the incorrect battery reading after rebooting. You'll have say 56%, once you reboot it will jump 15-30% and show, say 79%. Then it drops quickly down what it was prior to the reboot.
Doing a battery calibration in no way helps extend battery life, for me it just does the same thing that will happen after several cycles anyhow, it just saves you time from having to run multiple cycles to get your device and battery to sync up.
This is just what I personally do, I know people are going to post saying that doing a battery calibration is pointless, and probably point you to where google even said it, etc, etc. As far as the calibration doing anything special, it doesn't. I simply do this to get my device (When at 100%) to see my battery at 100% (4200mV). It works for me.

Battery is 3 months old.. use it rarely as it is my spare battery.. Does making it a spare battery affects it?

Yes! Once you start using a spare battery, you should ALWAYS alternate between the two batteries. Otherwise, it will affect the life of the battery.
Use One, Drain it, Use the other, Drain it, and repeat the cycle. Always charge your battery through your phone and not through a battery charger as this will charge the battery in highly optimum conditions and the phone will keep a track of the battery status.

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/
Sent from my HTC Sensation 4G using XDA

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.

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

Ya what he said.. put it in, charge use...charge.. calibration is just dumb. Ur phone knows how to handle the battery. Battstats are wiped at full charge anyways.

Whell my phone turn off under 20%(or around that) i made 3-4 full cycles first than wait some time in 100% and wipe batt stat and still same problem and bat reading is not proper all the time .. and the battery is new

It sounds like your battery is faulty, my ankers go down to 1% before switching off but they do drop very quickly when they reach 10%. Battery readings are accurate, apart from after restart when the % spikes upward then quickly drops back to the correct level.

All it does is delete your batterystats.bin file. It doesn't calibrate anything.

I bought a used HTC Sensation that came with an Anker battery. I don't know if the previous owner calibrated it or not. Would it still benefit me to calibrate it now?

[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?
