hey all,
I noticed that from the beginning, my battery doesnt charge to 100% fully. Battery monitor widget says its stuck at 2976mah instead of the 3100mah. Is this bad? i have rebooted the phone and did a whole charge cycle but it doesnt seem to work.
Does this mean my phone is broken?
thanks!

Does anyone else have the same problem? It turns off after reaching 30% and wen i try to turn it on, a symbol of a battery with red color in it blinks and shuts down again.. i have to charge it to use the tablet again. I'm on revolver rom 3.11.1.. and changing kernels wud not help..
pls help with any solutions...
Sounds like your battery isn't calibrated. How long (hours/days) does it take you to get from 100% down to the point of shut off? I've noticed mine will "forget" calibration if it's discharging for more than a few days. I.e. if I take it off the charger on Monday morning, by Saturday night it will be around 20%, and will turn itself off around 15%. Now, if I were to use it non stop, playing games or whatever, for the life of the battery, it will actually shut off around 2%.
TL;DR... Try this - https://market.android.com/details?id=com.nema.batterycalibration

it takes a long time to get from 100% to 99%, but after tat the battery drain in normal(i.e, time taken for 1% batt to be used is normal)... and while charging too, the charging will be stuck @ 99%.. i tried wiping battery stats in recovery, isnt tat the same as battery calib?
Hi
My battery for tablet is showing 97% charged as well as FULL word in settings for battery.
Dock is at 100% (showing it on dual battery widget)
How its possible that its full at 97% (tablet)?
Is there way to fix that?
Tnx
It's completely normal. The Transformer will not start charging the device until it goes below 95%. It considers anything above 95% as "full". I believe that it does this so that it's not constantly charging the battery... Just a guess though...
Hi everyone
My problem is.. my DS started to charge slowly.
Now it doesn't really charge slowly, If I check the voltage, I will get like 4220mv but as soon as it reaches that, the charging graph just goes flat.
If say I have charged it to 70% and it started going slow. i switch it off, place on the charger, and the lamp goes green. I turn it on, and it is showing 100%.
I have tried calibrations, diffirent kernels, wiping, factory resets e.t.c.
Another thing is that if I will run a v6 battery calibrator,it will show that actually I should have a 100% charge although a phone is showing only 70%.
So the summary: Phone charges normally when off (when recovery monitors charging), showing the correct voltage when on... But showing the wrong percentage if on charge.
Also sometimes if the battery is like 14% left. And I turn the phone off and then on again, it will show 22% bearing the same voltage as when it was 14%.
Question: Is there any way to tweak the battery indicator so it would show % values same as the v6 calibrator does it or is it a hardware fault, if yes, which part of it ?
This happens to me on my older (original) battery, but not my new one. I bought the second battery when this problem started happening. So, I think it's just a symptom of an old battery.
By the way, if you leave it on charge long enough, it will eventually jump up to 100%.
Other than this weird behaviour, it has no real impact on anything.

Thought so, mines been acting similarly lately, but strangely enough it seems to be getting better
I think I found out..
I actually purchased a new battery recently, because my old one was jumping like crazy and started discharging in a few hours..
This new battery I bought from a mobile repair shop.
It is a cheap chinese battery with no name, anyhow I just took it out to take a look at it...
And guess what, it sais 1200mah..
Can the phone be confused because of that ?
What voltage ranges do you guys get for 100% and 1%?
I bought a new EB40 for a friend's phone and am getting some weird effects. I've previously done the EB40 in Atrix HD in my own phone and it's been fine, but I haven't actually let it run down below 50% yet.
Full Story:
At first the phone wouldn't turn on, but the LED would turn on when I plugged it into the charger. I left it on the charger for 10 minutes and then it would turn on to the battery charging screen, reporting 1% battery left.
I then made it boot into the OS. After a couple minutes charging, it jumped to 100%. I left it on for an hour, then disconnected it, and then it was slowly going down like normal. However, after it hit 85% or so, it just suddenly died.
Then I had to charge it and it was back to 1% and the same thing repeated.
I tried clearing battery stats (/data/system/batterystats.bin) but it seemed similar. Now I'm trying to run the battery till it dies, it's been at 1% for quite a while. Then I'll charge it back to 100%, but is it possible I got a dud?
We ran it down to 1% again, it died, and and it went back up to 100% again. I'm figuring once I get down to the real 1% and dies, when I turn it on it won't be at 100% like every other time. Then perhaps it will charge all the way up to the real 100%.
So far it's been like this voltage wise:
3.966V: 3%
...
3.725V: 1%
died
3.696V: 100%
...
3.663V: 1%
died
3.661V: 100%

i believe when these batterys are fully charged it should be around 4.300 so if the most your getting up to is 3.700 there is probably something wrong
My phone battery remains in charge until the morning and closes at 1% seems to be. I fill with an external charger is 100% plug in but the phone is going on and off 1%. I tried another battery still the same result.
