Battery status jumps from 70 to 100 ??

My Desire battery while charging the status jumps from 70 % to 100% immediately.
I have been using battery calibrator application.
If the battery is fully charged, my desire turns off at 30%. That means in anyway my desire only uses 70% of the battery.
:cryingls help me

try this
Charge till full when powered on
power off
charge till full again
boot into recovery
wipe battery stats
boot and continue to use as normal

Thanx... Will try this...

Did u do the guide i posted? All those battery calibrate apps do is wipe the battery stats, and thats not how to calibrate a battery

Sorry.. I missed the last step in my previous post. Allow the battery to drain completely before charging again..

yh, in the app once u check the boxes in settings and set the values in learn prep, turn on learn mode and drain ur battery, once it hits the value, a popup screen will say learn mode detected, plug in charger. (or something like that) just have the charger ready coz u only got a few seconds to plug it in then it shuts down lol

Nothing works for me... I followed the battery calibration steps.. But fails.. Still have the same issue...

Do you have these problems when you charge via usb or directly from the plug? As the second procedure is much faster, you can have some erroneous battery capacity readings from time to time, especially in (not really old but still bit) aged batteries.
Try before using the calibration tool the following: When the green LED appears, sign of a full charged battery, unplug your charger and turn off your phone for 3-4 minutes (you can even pull off your battery for a while). Turn it on back on, plug the charger and wait until fully charged. At this point reset your battery stats through the calibration app.
edit: oops, it is essentialy the first solution posted but without going into recovery. The calibration tool does this automatically for you.

I have the opposite problem
My charging is quite accurate but while discharging, the phone suddenly dies at a random battery level below 20%, without becoming close to zero

[Q] xperia s battery dead

hello, so my phone turned off after the battery finished normally but after that it was accidentally turned back on several times by the power button being pushed from my pocket. now it shows a red led when plugged in and after a while it turns on the off when it reaches the lock screen i dont know what to do please help

I am having trouble comprehending (sorry)
But what i understand is:
Your phone FINISHED charging and then it turned off (by itself? or did you do it?). While in off mode, it was turned on (but what u mean several times?)
And the red LED means low charge :/ and it reboots and turns off at the lock screen etc
Anyway:
I would recommend reflashing the firmware, only if you have enough battery to do so

thanks for the reply but no thats not what i mean. what i mean is my phones battary is 0% and when i put it to charge it charges for 2 min then turns back on but when it reaches the lockscreen it wont have enough battary so it automatically turns off and the process repeats

Yeah i had that problem too dont panic.If ur on a custom kernel,put the phone on charging,when led is red,phone off.Keep the phone in ur hands for 10 - 15 min.When kernel logo appears and led is pink press the volume up button.Flash other kernel in recovery.
There z no other method except this,even fastboot will not work
Press Thanks

well did that but it didnt work either the problem is that my battery is on 0% so it didnt work

This has happen to me kany times, this is what you do:
-First charge it when its off untill it boots
-Then do a hard power off (vol + until three vibrations)
-once its off plug in your charger and it will enter offline charging and just let it charge till about 20%
-Then you can turn it on

thanks for the reply but it still reboots, im a noob i know but does this have anything to do with bootloops or anything

No its usually a kernel problem, as many others have had this problem before. What kernel and ROM/firmware are you using? Nova kernel has such a problem for offline charging.

[Q] Won't charge beyond 57%

For the last 2 days my HOX refuses to charge beyond 57%, I haven't got anything running in the background which could be sucking up the energy as it tries to charge, does this sound like it could be a fault with the battery?

Have you tried battery calibration tool? or reset battery stats etc

Try charging with the phone switched off.

Can you get into bootloader otherwise your phone seems to be hard bricked.

no i cannot not even led lights up on connecting charger , do you think using samsung's charge would have caused it ?

so guys it's solved now , i disassembled the phone and found that metal plate at back side of phone was causing short circuit and preventing it from startup , so i bend it a little so that it won't cause it now huraay

One X keeps powering down

HOX powering down every time battery reaches approx 15% then when I turn the phone on again the phone checks the Sim card then powers off again (btw I'm unrooted) ..What do u think should I do? Thank you in advance

Wierdly enough, this hapend to me too, yesterday. I m on viper 3.7.5. I think the battery. Was not calibrated properly.
Sent from my Viper HOX

If that is the problem, then I have a way to recalibrate the battery : 1) power off .. 2) charge for 10 min .. 3) press the power key and both the volume keys for 2 straight minutes .. Aaand that should recalibrate the battery
