I am using the Sensation on stock ROM..and about two weeks ago got a minor update to it (which provided the power saver option on the quick settings menu)..And since about a week now, my phone takes an elongated time to charge..previously, it took only about 2 hours to fully charge the phone, but now it takes more than 3 hours..plus, it takes only about 1.5 hours to charge from 0% to 80%, but afterwards, it takes more than another 1.5 hours to charge the remaining 20%..but after about 90% it literally stops charging further, no matter how long I keep the phone plugged to the charger..But when I restart the phone at that time, it indicates the battery level as 100%..
Does anyone else has the similar kind of problem? And can anyone please suggest me what to do? Is it a problem with my battery or is it a software issue? Please help me..
Thanks in advance..

Perhaps you need to reset the "stats" of the battery ?
Charge the device to full battery; let it keep charging until the battery says it is fully charged. Do not just wait until the light is green, it isn't always fully charged, causing a lot of inaccuracies. (You can check by going to: Settings » About device » Status » Battery Level = Full.)
Boot to recovery mode and delete the battery stats
NOTE: To have the most accurate of battery stats, reboot the device immediately after wiping the battery stats and wait for CyanogenMod to boot completely to the desktop. Once your entire boot is done and you have full access to the device, go ahead and pull the charger and continue with this troubleshooter.
Do not charge the device until after draining the battery completely, resulting in it automatically shutting off.
Recharge the device completely and then use as you normally would.

I am also facing almost same issues with battery. The phone charges very fast from 0% to around 75%. The remaining 75% to 100% takes a long time. But it does reach 100%. It doesnt stop before. And if I reboot the phone when charge is 80% or 90% it will immediately show 100% on reboot. So which value was correct? Before or after reboot?
Another thing is during the day when I am using the phone and the battery is at any particluar level for ex. 45%. And I reboot the phone for any reason. After rebooting the battery level is shown as increased to 50% or any other value. How does battery increase on rebooting the phone?
My theory is that HTC Sensation is unable to read battery level accurately and therefore such incorrect values are reported. BTW this happens on both the stock battery and my current Anker 1900mAh battery.
Hey mate, did this error started to occur after you updated your phone or was it there prior to the update as well?
This situation was there before the update too. Maybe some experts here will give their opinion on this.

Seems I fixed mine. I had put an extended battery on this guy, and it would never change in battery level. I would have to reboot the phone to get it to register the new power level.
Discharge your phone to 0% until it shuts off. Try to turn the phone on several times to make sure its discharged (should shut off immediately). Charge the phone to 100% without unplugging it (will take a while, do it over night).
Today my % seems to be registering and no need to reboot the phone to change it. HTC tech support claimed they had nothing to do with the battery manufacturing so they wont help you.
if you reboot your phone how accurate is it to the actual battery meter showing you the percentage? I am at 6 percent left on my phone in hopes of discharging it and than charging it full to get mine to work

It will still probably jump down about 10% but it will sit there for a LONG time until the system is actually to that percent. My recommendation is dont reboot the phone if you want to keep accurate %. The rebooted value I dont believe indicates actual battery life remaining. There is a communication problem between the phone and the battery - HTC confirmed this is going to be patched (on the phone with them last night).
This happened twice today..
For e.g: If my battery is showing 15% and then i restart my phone it suddenly shows 50% remaining..
Am using Battery Indicator to show me in % how much is remaining (though even the htc battery shows the difference in this case)
Any idea why is this happening and how to solve this??
Oh and how to stop the: Show Me app?? Keeps restarting and sucking my battery..
Could someone please help me out here with this weird problem??
It keeps happening everytime i restart my Sensation..
Try wiping your battery stats from CWM.Then charge battery fully>drain fully>then charge again it should be calibrated. oh and use startup cleaner in the market.

Its a 1 day old Sensation.. Havent rooted it yet..
I saw the same with my mine. I allowed the battery to drain until the phone shut off and recharged over night to 100%. I did that for a few cycles and mine seems fine now.
The battery % indicators only show what the phone software *thinks* it currently is.
The Sensation battery ranges from approx 4200mV (full) to 3000mV (empty).
The problem is sometimes the phone thinks those numbers are different. E.g. when you turn on your phone for the very first time, or flash a new ROM, if your battery was half full at 3700mV the phone would then think that was the 100% level (why they say charge a battery fully for a long time before turning your phone on for the first time).
This leads to various funnies such as a battery seemingly staying full for ages (the phone thinks 100% is much less than 4200mV so until you drop to the phones level your battery %age doesn't go down), and seemingly rapid drains where you end up with less than 10% left - but probably find in reality if you left it your battery would go on for ages at 0%.
Over time it learns, but best to wipe your stats after a long charge so it knows that 4200mV is 100%, and then don't charge your phone again until it physically runs out of juice so it knows what is 0%.
Another useful tip is to install the free BatteryLife widget from CurveFish from the market. That shows you the current voltage level as well as %age, so armed with the knowledge that full = approx 4200mV and empty = approx 3000mV you get an exact idea of how much you have left.
Mine does the same thing even draining/charging for few cycles

Yeah... I went to sleep with 100% charged and when i woke up it was yet 100% charged.. And when i check the battery stats it shows 0s but i was asleep for 8 hours.. Any way to solve this on an unrooted phone?
I had the same problem today too! Thought my battery was kicking ass...turns out it was 18% when I restarted my phone

What did you do about it?
Anyone know what to do about this to an unrooted phone??
Or is this a defective piece and i should get a replacement??
Mines has done the same but I haven't had the chance to calibrate it yet to know if that'll help. It has helped on previous phones. I don't think your device is defective though.

How do you calibrate an unrooted device??
I think it calibrates itself after a few charge/discharge cycles. Always charge it a lot longer than when the green light comes on (because if the phone thinks the 100% level is a lot lower than it should be, that green light may come on early), and for the first couple of charges let it dry out rather than topping up.
And install that BatteryLife widget from CurveFish, then you can look at the voltage. 4200mV = full, 3000mv = empty, regardless of what your battery %age says. Mine currently says 51% and 3753mV.
Having the same problem here, restarted my phone afew times now and the battery % keeps going up, then dropping rapidly! :s

Hey Guys
I bought my HTC Sensation about 3-4 days ago. No root, No S-OFF. For past few days, i followed battery charging procedure, drained battery completely, left phone off, and charged it. I did same procedure few times. Doing this procedure really improved battery life on HTC Incredible S.
Anyway, last night, battery was running low 30% after 14 hr use. I needed alarm for morning so, at 10pm i plug phone to charger and left it on. 4:30 am, got up, and orange led light (charger indicator) still on. Check phone, and it still charging. Checked battery and it shows 50% charge. Anyway unplugged it, fetched to work put on charge, after about 1.30 hr still at 60%.
Decided to restart phone, as soon i did restart, battery went back to 100%.
Does anyone experienced this?
Nope, that sounds weird. I would suggest battery calibration for you if this is a reoccuring thing.
Sent from my HTC Sensation
Do i need S-OFF or rooting to get battery calibrated?
Is any other way to get it calibrated without root or S-OFF?
Oh crap. I think you do need to be rooted to use the calibration app. My bad. Try using the search button? I would do it, but I'm not on my computer now.

My battery took forever to charge the 1st couple of times... After about 3/4 charges it sorted itselft out. Good luck
I am kinder hoping it was one of software glitch, hopefully it won't happen again. Will report back after few more charge cycles.

Mine also took a long time the first few charges (probably 5 hours or so). It now charges in well under 3 hours.
Same here. When new & after a factory reset, it will take a LONG time to recharge. But will sort out after a few cycles.
Thanks guys,
I don't know what happens, but after 5hr use (heavy use), few voice calls (one about 30 min) emails sync every 15 min. Battery shows me that i used only 9%, impressive! I installed battery widget to see if some software issue, but seems to be only 1% out. Phone shows 90% life left, widget 91% (but still calibrating)
Hi all,
There's this problem with my phone that everytime I charge it, it takes an elongated time to do so. This issue first emerged when I was on stock GB after a minor OTA update which added the power saver toggle to the quick settings menu..The problem is that it takes about 4-5 hours to fully charge the phone, and if I rebooted in the middle of charging when it's about 70% or 80%, it suddenly shows that the phone is fully charged, and the indicator becomes green! But afterwards the battery drains as quickly!
Now I have S-Off and using ARHD 6.6.3 ROM, but it seems the problem persists ..I wiped battery stats as soon as I flashed the ROM as well..Although it's not a problem I cannot live with, it's annoying enough when it happens.
Can someone please help me? And suggest me what to do?

its common thing...the battery calibration is not proper that's all...
also you need to wipe stats once you charge your phone to 100%
then battery will try to calibrate ...and after 3-4 full complete cycles (100-0 and 0-100)
the battery will settle..
the battery drain will be there ...whenever you flash a rom or flash a kernel....battery only settles atleast after 2 full cycles
EDIT: also download currentwidget from market..as the name says its a widget..so you will see it in widgets once you installed it...this will give you more proper reading of battery...when you plug your phone to charge...and when current widget reads 0mah then your battery is charged completely...(it might take a long time to read 0mah...but charge it until you see 0mah)..then wipe the battery stats...so after this battery calibration will be proper
Also the sudden jump of battery percentage is due to improper battery calibration
so dont worry you got no problem
So
I read somewhere that you are not supposed to let the phone go to zero because it could cause your phone to not power back on anymore..is this fact. I couldn't find where I read it to back and read again. Mine has been doing some weird things as well...the led turns green before it is 100% and it goes from 100% and drops to like 89% out of no where.

when i meant 100%-0% means until your phone turns off due to less power..it might not(or won't be) be 0% then
as i told you that kind of jumps are common ...in my case it went to 60% to 100% when i rebooted ...also the dropping used to be in large scale too

Hi everyone I have a problem.
When I charge my battery it charges normally to 70 % after that it takes about 3 to 4 hours to charge till it reaches 100 % but if I reboot my device when it's charged to about 75% the Battery is suddenly fully charged.
I have tried to calibrated it but it didn't help.
I have this problem on every rom. What can the cause of the problem be.
It used to charge normally at first when I bought.
I have my desire s for one year now.
My device is rooted via revolutionary and s-off.
Thanks in advance.

Have a look at your battery for any swelling or signs of damage on the battery, it is possible that your battery is shot.
Re: battery...
Could it be that with the reboot,
device wipes its battery stats and looses the info?
(Or is it happening only during flash)
my phone has that same symptoms, but it happens mainly
, when i flash a rom, forgetting fully charge the battery before- after reboot it indicates full charge..
Edit: according to amidabuddha, htc has implemented safety switch in to charging procedure,
, when the load reaches certain level- it slows down
Then begins to indicate ' fully loaded' before
It realy gets to it- that is suposed to lengthen live of the battery,
but three to four hours sounds unusual...
Edit 2. When during charging battery gets to hot, charging stops as well...
Me too, charging from 0-70% needs 1,5-2 hours then 70-95% needs 4 hours, 95-100% just needs couple minutes, Idk why this happens, the battery stat says health...
When in the middle of charging I reboot the device, the level rises up anomaly, ex. The device is charging, and the level is 12 and I reboot, when I get back to homescreen it says 45%..
Also, the led changes from orange to yellow not when the level on fully charged, usually on the 90%.. my device is almost 2 year old

no, there is much difference in time.
From my experience, this behaviour is due to battery age. It started happening after about a year for me. I bought a new battery and the problem went away.
But I never had any real problems as a result of the slow charging of the old battery. If you recharge overnight, then it will have sufficient time to fully charge.
Based on what I now know, I wouldn't replace the battery until it stops holding its charge.
