I decided to try resetting the battery stats, charged the phone to 100%, then turned off the phone and plugged in the charger and now the green battery icon looks like it is about 90% full, but never goes to 100% (I've left it plugged in for 3 hours since). Any ideas?
Update: Full discharge and recharge seems to have done the trick!
Let the battery drain to zero. Plug in for a min then unplug to see where its at. If its at 1% charge it back to full and reset stats again...if it says something weird like 12% or more or less let it drain and die again until its at 1% then recharge and reset stats. Then let die completely before recharging

Will try and and report back - thanks for the suggestion!
I've found that my phone won't charge all the way unless I'm using the wall charger or car charger that I got with the phone I had tried using a charger from one of my old phone's and it actually made the phone go into sync mode and still didn't charge it all the way sometimes even when it's plugged into the computer it wont charge all the way

Good Morning everybody!
I think I have a defective thunderbolt battery, sometimes when I pull my phone off the charger it drops to 95%. Funny thing this is not a everyday thing. Anybody having a similar problem like this? Sorry if this been discuss before. Have a bless day everybody...on my way to the office.
I have the same thing happen. There is something goofy with how the meter reports battery level. If you reboot your phone it drops even more.

Yea I notice that too. I seen my battery drop down 15 percent after rebooting. Is the battery defective? Or the phone is defective?
Bump charge it. Charge it all the way. Unplug, turn it off, then on, and keep charging.

The phone/battery aren't defective. I have the extended battery so I never bump charge it, but he is right. Charge it up until your charging light goes green, unplug it and then turn it off. Once it shuts down, plug it back in and will now be orange. Charge it until it's green again. Sometimes it will take a few minutes, sometimes an hour. I'm also color blind so I can never tell whether that damned light is red/orange/green. >.<

He gonna have to turn it on then plug the charger in. If left off then plugged in the phone will boot into recovery.

charge ur batt. to 100%, then go into cwm and clear batt. stats, when u turn it back on it should b around 80-85% then charge all the way back full again and then u will b at full capacity

is this all the time we have to do, I have the extended battery and it doesnt drop and I read about clearing the batterystats.bin but is this something we always have to do when we charge the phone? when I use the standard stock battery it drops with no problem
I didn't have any issues until I wiped the battery stats and now, my battery is constantly inconsistent. I would not recommend doing it as it has nothing but a pain in my arse since.
Have tried "bumping it" which essentially means to charge it to 100%, restart it, then charge it back again from whatever it dropped to.. Mine initially was around 85ish.. After a few "bumps" it crept up to 90 or 91 and then wouldn't go any higher. I charged it back to 100% and decided to follow the advice from another article which said to let it deplete to 0%.. In doing that, surprisingly it "froze" in a couple of places, I don't recall the 1st % but the 2nd % was definitely at the 28% mark. It literally sat there for a good 2+ hours with screen on max and didn't go down. Eventually it went down to 1% and I charged it back to 100%.
Issues still remain, wondering if I should've let it completely die out and force itself off?
Lesson: DO NOT MESS WITH BATTERY STATS with CW.

Where do I get into CWM, to do this?
Thanks for your help everybody! I'm sorry if this is a dumb question...what is CWM? My device is stock.
CWM = Clockwork Mod.. Goto Market, download ROM manager, then you can flash CWM. Not sure if that'll do you any good if you're not rooted though.
why when I reboot my phone like 15% of the battery life drops I love this damn phone man...i cant put it down while im at work
The battery reading after reboot is wierd.
Yesterday I was at 51% and draining are at a pretty steady rate like normal. After rebooting, it showed 41% but then it say at 41% for AWHILE.. after like an hour, it read 40% and started discharging at the normal rate.
Your battery gauge is lying to you (and it's not such a bad thing)

Thanks for the repost, I had skimmed this thread earlier but don't recall it being so detailed. Seems like the moral of the story is that while "bump charging" works, it's not really recommended as it can reduce the overall life of the battery. Wonderful, now I regret ever messing with the battery stats at all, although I can't say for sure I didn't have this issue prior to doing so.
My OEM battery wouldn't hold a charge even after charging it all day... I took it to the VZ store and they replaced it for free...... I also just bought the larger 2750 mAh battery.... works great!
I'm trying to calibrate my NS (i9020T) because it seems like battery drains quite fast after frequent flashing ROMs. Last time I calibrated was about 4 months ago.
But the problem is that it won't charge beyond 99%. It used to charge up to 100% before if I leave the screen on.
But don't I need to get battery % to 100% (that's what calibration app says)..?
How can I get it back to 100% charge?
Thanks!

Not sure if it works ffor ns, but drain your battery, go to data/system and delete batterystat or something along those lines and reboot. Let it charge for awhile and it should go to 100% . If it works you don't need to calibrate anymore as that's how normal apps calibrate.

drain your battery, delete the batterystats.bin, reboot, then charge all the way. chances are is that you had to wait a bit longer for it to hit 100%. when i charge my phone to 100, sometimes it takes an hour to go from 99 to 100%. be patient, if that 1% is worth it. the more you play with your phone between 99 and 100%, the longer it will take.

I waited 5 hours but it was still at 99%. I had to leave home so I couldn't charge any longer...
So drain it first, delete batterystats.bin, and it should charge to 100%? Because the app I downloaded says, charge it to 100% then delete batterystats.bin.. etc.

you must had something running in the background. believe me, the different between 99 and 100 is almost non-existant
The last 10-20% trickles in. 5hours is way too long though. What does your voltz read bc you can have a full charge as far as voltz go but may be getting a faulty % reading on the charge.
If you use the apk make sure you don't power off or you will regenerate the battstat through normal process and then the app is pointless. Try charging overnight and see if you can get to 100%.
Fyi/beware draining your battery to 0 is not good. Some batteries and phones have a hard time getting through first boot when there is little to no charge in the battery. Whenever I use the calibration apk, I never go below 10%. Anything below that can cause some funk.
I drained it all the way and deleted batterystats.bin, charged it all the way back overnight, but it doesn't go over 99% for many hours. I stopped all the services I could possible (kept only the essentials)...
Current Charge: 99%
Voltage: 4.176 mV

So it's simply misinterpretation of the battery that it doesn't read 100%?
Well, I started calibrating about an hour ago. I thought it shouldn't matter too much.

Yes your phone sometimes gets out of sync with its self and starts thinking that its fully charged or fully discharged when its not. The way I typically calibrate my battery is to turn it off and let it charge until it stops (this is easy to see since the screen lights up and the battery shown on the screen stops unfilling and refilling). I then unplug it and boot it up. Again, shut it down and plug it in and let it charge until it thinks its full. Again, turn it on this time letting it charge to what it thinks is full while on. Finally restart into CWM and use its too for wiping battery stats. After all that I also like to let it die before I plug it in again.

Are you overclocking/undervolting? If yes, then stop.
Otherwise change your battery.
Do this, preferably with a clean/new ROM install.
When the phone dies, charge it for 1-2 minutes just enough for you to enter recovery and clear battery stats.
Once battery stats are cleared power off the phone and leave it off and let it charge while you sleep.
When you wake up, power on the phone and use it normally until it dies. Do not reboot the phone during this time.
When the phone has died again, leave it off to charge fully again, once this second charge is done you are now free to use your phone as normal.
Some people claim clearing battery stats does nothing, and may be true. But I have always done my charging this way and it may be why all my phones still have the stock battery with excellent battery life.
Its also best to do this at night when you are asleep to let it charge all the way.

I charge my phone every night to 100. It was at 100 this morning and I unplugged it and it was at 88. Why was this caused and what can I do to fix it?
Are you awake and unplugging it when it reaches 100% at night?
Do you have a task manager or batt app installed to tell you whats eating away at your battery?
Need more info. Does it literally go from 100% to 88% once you unplug it?

yes it did go from 100 to 88 after unplug. and no im not awake, i put it on the charger around 10, fall asleep, unplug at 6 when i wake up. and yes i have gsam battery monitor from the play store to see anything that may cause a battery drain.

its stock unrooted doe
As soon as it reaches 100 it starts discharging again but not at normal rate since it's still unplugged it can't keep charging
When you wake up unplug your phone and put it back in you'll notice it'll keep charging or you can test it yourself. Charge till 100 wait a few and unplug and plug quickly, it will charge once again for awhile even if it shows 100

Hello, i'll recieve a new battery tomorrow. (original htc sensation one)
Do i have to charge it with the phone closed for like 2 days before actually using it ?
No need
Just take couple of charging cycles..
Do a full charging at 1st , use cellphone till battery downs to 6-7%
Recharge again to 100%
Do this 3-4 times to see battery backup

Ditto. This procedure should be just fine. Use your phone as you would normally. When it gets low, plug it in and charge it up to 100%. Do this another 2-3 times and you should be set.

Ok, just got my battery.
I didnt charge it since i got it. So i simply charge it to 100% when it gets to 2%.
After a few charges it should recognise the new battery, right?
Its not like i have to clear battery cache or let the phone to discharge completly and afterwards to let it charge closed?
Edit: it already lasts much longer
