My phone keeps turning off when I hit 9%. I plug it in and it shows 0% with an empty battery sign. I am on andybones 5.0 rom but I have tried many different roms and this keeps happening. How can I recalibrate my battery so it is more accurate?

I think you can download an app that will clear your battery history and recalibrate it.

Is this normal. I did try and do a search in my defence.
Yes. It is like that by design. It stops charging at around 95-98%. Its to prevent you from overcharging the battery.

This is a known issue. You can try and reset battery stats in cwm when your battery is charged and/or emptied. It works for some and not for others. I haven't noticed my battery lasting any less when my battery doesn't "charge" past 97%
There have been some discussion on this. I get about 97% myself. From what I've read you may get full charge if you let it drain all the way. I don't do that myself. Very happy with battery life as is.
I used to get 100% before I switched to the Vegan rom.

Either let it drain until it shuts off a few times and then charge it all the way up or if that doesn't work, use CWM to delete the battery stats when it's at 95% (full, with a GREEN light - not charging, with a red light) and then let it drain until it shuts off on it's own.
I did this a long time ago (delete the stats) and it's been perfect since. Charges to 100% and does indeed show battery at almost empty before it shuts off.
Good Luck.
Still no go here but it can get tom 96%... lol
I am sitting a 98% with VEGAn.
I am now having an issue where u can use the device, then I turn it off, and
turn it on the next morning and see about 5 to 10% of my battery was drained.
Confirmed Fix
Confirmed fix for me on Vegan 5.1. Letting battery drain down to zero and shutoff the tablet... reached 100% on next charge. Now the indicator charges to 100% every time.
tried this and still no luck . still get to 95-6% bugger
Vegan here..this is how I fixed it:
1) Drain it till it shuts off, try restarting it a few time to make sure its dead.
2) Once dead, plug it in, boot into clockworkx, and reset battery status (do this quickly)
3) restart, and leave plugged in idling till fully charged
4) use and enjoy a accurate battery level!!

You have to remember that in order to install some apps out there, you have to give them permission to use the internet and to interact with your device autonomously. I have found a few apps that were pulling my tablet out of sleep mode and turning on the wireless to download ads or other updates, and that (along with the length of time to shut back down) was affecting my battery life.
I would say to go back and review what you've installed, and to also check your screen timeout settings. Just doing that saved me quite a bit of overnight battery loss.

Guys,
when i keep my HTC sensation on charging, it gets charged till 99%, and it never increases, even though i do not remove the charging. The indicator light remains ORANGE... sometimes it does go to 100% with the light turned GREEN, but 9 out of 10 times, it is stuck at 99%.
Is anyone else getting the same problem???
I don't have your phone, but I do know that sometimes when you load roms while your battery is low, the battery stats will be messed up. Or just after a while your battery stats screw up due to charging while the battery is not full..
Try charging fully (if you can get to 99% only thats fine). Then boot into recovery and wipe the battery stats. (if you have that option in whatever recovery you have). Then reboot your phone. Let it drain completely. When I mean completely I mean, when your phone dies, turn it on again and wait till it dies again. Then finally, just charge to the full. If this problem persists, it may be a hardware glitch? lol... Or some Rom glitch? What ROM are you running anyways? If you are at all..?
Hope I helped

I am using the stock ROM 1.28.xxx.
Going into the recovery would wipe out my phone data? and could you elaborate a little more on this process, like the steps and options to do it.
Thanks.
i don't think the problem is in your battery stats because it is a stock rom. Try leaving it on charge overnight to see if you will get green led indicator. Mine gets green when it is fully charged.

Do you have a custom recovery image? That is important. And are you rooted?

Yes I agree with you.. He should probably just leave it to charge overnight. Sometimes it takes very long to get from 99% to 100%.
It is normal, the last 1% takes a while sometimes. But it will charge to 100% if you let the phone charge.

Sensation is not S-OFF (bootloader is locked) yet so almost none of us have custom images. Only %0,001 of users get S-OFF on very very luck. Just informing

which is your concern...
a) the LED being orange at 99%
b) not reaching 100%
?
personally I would not worry about b)
as for a), I thought it went green once it reached ~ 90%?
EDIT: quick correction

NO,if the battery reaches 100%, it turns the battery GREEN, but it hardly reaches to 100%, most of the time it is stuck at 99%.

Its soz of ur batt make..... if u r curious replace the new batt and charge it first it will turn green faster coz batt r of different lot number... do not worry jst follow the guide in batt caliberation post.
Anyone else getting huge changes in battery percentage?
I was running my phone with seemingly low battery use earlier today. Then it randomly rebooted and I was at like 14% battery. Used my phone till it was at 1% and died. Now I just plugged it in, and after about 20 minutes I have a green LED and it says I am 90% charged! What the hell?
Running CM9 Mar 27 build 2, 3.32 firmware.
seems to me like your battery isnt calibrated properly
Its happened to me many times, due to flashing roms. I was on 2% for almost a day lol
Drain the battery till its completely dead... Switch it on just to make sure it wont power on...
Then charge to 100% no pauses... Then delete battery stats.

I heard that this battery calibration thing was a myth proven wrong by HTC or something?
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

Thanks mate! I will try this out! cheers!
I don't know what anyone means by all this 'download mode' and 'recovery mode' etc, I got my phone last month and I am new to it.
The battery life has always been quite lame, but this morning I was charging my phone and it was on 5% according to the battery widget.
Then it turned off, and now it won't turn back on.
It comes up with an empty battery but instead of the green bar moving to charge it, it is empty with a yellow triangle with another battery inside with a line going through it!
I have left it alone but it vibrates every five-ten minutes spontaneously, and occasionally shows that empty battery again.
I have tried removing the battery then putting it back and charging it from different sockets/from my pc - nothing is working.
please help me.
