Recently i buy battery from market which is not showing 100% after charging more than 10hrs.
it always show 99% not 100% & green light is not showing. But when phone is switched off i see green light.
battery life is satisfactory. i do battery recalibration. now what can i do?

how do you know if your backup battery is dead my blue angel is dead when i put it on charge with no battery the red light is on but if i connect a battery the light goes out its not the main battery cos i have tried 3 does the red light show that the back up battery is flat if you do not have a main battery fitted hope you understand that thanks
put a fully charged battery in it and leave it overnight
then charge it for another 4 hours, then take it off charge and check what the battery pane in the settings panel shows.
When the power is on the TP2 the red LED charge light is on. the icon in the task bar changes to show that it is plugged in. but after sitting for hours the battery only drains further. If i power the TP2 down plug it up the red LED comes on and the battery charges fully to 100% then goes to green. I have bought new battery and charger. any ideas? note it is allowed to charge via usb in the settings. thanks folks
This is NOT a issue. It's a feature.
Phone does charge to 100%, but later the electricity is cut off until it reaches ~95% (or something like that). It prevents the battery from overcharging and saves important battery lifetime cycles. If it would be charged constantly from 99% to 100% the battery would be dead in a month.
Problem:
I have been reading as many posts as possible but I haven't come across my exact situation. I apologize if this is posted elsewhere.
I am running a rooted Dinc using CyanogenMod 7.0.3. If I charge the phone while it's powered on, the amber led turns green as soon as the battery indicator hits 100%. However, recently I've noticed that if the battery is close to being full, say 90%, and i power it off to charge it, it actually takes longer for the amber led to turn green. It might take 20-30 minutes longer.
I've also noticed the amber light turn green when the indicator only showed 92%. In trying something different I also noticed that if I charge the phone while it's powered on, then turn the phone off, the led goes amber and takes another 20 minutes to turn green again (I might be accidentally bump charging in this example but I'm not sure).
Attempted Solution:
I've read that a battery recalibration might help. I tried one method that requires the battery to be pulled after a full charge, but my phone won't boot while plugged into the wall if there's no battery. Then I tried booting into recovery, where I found an option to reset the battery stats... which I just did about 5 minutes ago.
I'm going to see how things go tomorrow, but is this normal? Has anyone else experienced these things? Thanks.

The kernel and the hardware charge it in different ways. That's why there are differences. DInc is famous for ending charging before the battery reads full. There's already a thread on that. there's not much point in getting hung up on how that thing charges. Be glad yours isn't like mine; a battery that discharges faster than it charges. Seriously.

Before I had a fast charge kernel (thanks Chad!) Using GPS with the stock VZW car charger, my battery would go down while it was on the charger!
Sent from my ADR6300 using XDA App
On AOSP roms, the LED will turn green at 90% and charge slower from 90%-100%. Perfectly normal, and I think on any rom it will charge slowly from 90%-100% to protect the battery.
The battery will charge further when you turn the phone off, what you described is what's known as bump charging. If you do this, you should notice a slower drop from 100%-90% than usual, because the battery is charged to a "true" 100%. When the phone is on and charging (above 90%), it simply keeps the battery above 90% even if it says it's fully charged, and this is why the inc is notorious for the quick 100%-90% drop.
If you do a bump charge and then clear the battery stats and use the battery calibration app will you need to bump charge again or will it know what the true 100% capacity is and keep the droid lasting longer. Not noticing much of a diffrence when i went from 1300 battery to a 1500. May get a bigger batter that'll fit the stock battery door cause I'm trying to get the best battery life i can get.
Thanks guys, I appreciate the help. I think something else that has thrown me off is that before I rooted the phone I wasn't able to see the actual battery percentage in numbers... all I could see was the battery icon. Things are now making more sense.
After recalibrating my battery I bump charged the other day and I was able to get almost 2 days out of my phone on light usage. Without bumping, I was able to end my day yesterday at 50% under my normal usage. Which is a noticeable improvement. Normally I end the day with about 10-20%. The big test will be once I go back to work next week. The cell reception is real spotty in my classroom, which I know makes the cell radio work harder.
Thanks again.
I found a lot of answers I was having about battery charging in this thread:
Your battery gauge is lying to you (and it's not such a bad thing)
I always turn off the phone before charging, but this phone does not have a number percent on the display when charging, so I wait until the indicator light is green, but every time I turn on the phone, it is actually around 97%, not 100%
This messed up my attempts to calibrate the battery, so can someone explain how to tell when it charged to 100% when there is no percent number on the screen when charging...
Charge it while it's on till it's 100%
i have read that charging while on is not good for the battery, but all I want to know is does the green notification light mean it is 100%? so is something wrong with my phone that it is only at 97%?
With modern batteries, it won't make that much of an impact on the battery if you charge it while it is on or not. Because the phone is off, it will charge faster however.
Hi there,
does anyone know or can develop android app, that can be used to show battery icon and percentage based on battery voltage and set up by user settings?
Problem is that battery indicator is stuck at 20%.
Phone was drowned, repaired, battery was replaced with new and second hand , other roms, custom and oem was used, rooted, calibration apps was tried, but, no success.
Led indicator indicates normally green at full charge, orange around 30% and red below 15%. Battery stamina is good, about 1,5 days use. Apps see voltage and know when battery is 100%, but.... stock android indicator stays always on 20% , show charging when plugged in, but stuck on 20%.
Tried also many button reset combinations etc...

Nah, not the thing i'm asking for...
Any developer wanna do it ? I will pay for it please !!!
Hi
I just want to say that I have the same problem...only showing 20% battery.
I had problem whit the charging and left it for repair in Bangkok when I was there.when I got the phone back it only shows 20% I know the green light means I have fully charged.
So if I restart the phone when I sẽ the green light it shows 100% but not under that.
Make me so angry..only 20% and 100%
And it is werry bad becouse it will not allowing update if you only have 20%
So I hope someone have a solution to this problem..
