battery - Captivate General

i was charging with my phone off from 0 (battery calibration) but then I turned it on to check something.
Prior to turning on the phone, the battery charging icon showed 30-40%. After i turned it on it jumped to 67% and when i turned the phone off again, the green filling was around the 70% mark.
Why is there such a big jump? Does this mean i lost 30% charge?

(Q) how to know when anker battery is fully charged

When I'm charging the banker battery, the notification will go green so I think its fully charged. But I've noticed that when I unhook the cable and use the phone for a while, then plug it back in, the notification light lights green. So I'm wondering, does the light turn green for the banker battery at a certain level even though its not fully charged?
Should I let it sit on the charger a couple more hours after the light turns green?

Charge it til it turns green, then turn the device off and charge it for another hour with it being off and it will be fully charged. This is known as bump charging, but does decrease the long-term life of your battery if it is done too often.

+1 to that!
try this: charge battery until the LED turns green. Unplug & then wait until your battery is no longer showing 100% before you try to plug it back in. Mine will show 100% for a while before going down in percentage.
I thought android phones showed green at some point in the 90 percentile range? So if your at 98% it will still be green.
From what I understand because of the old battery the phone thinks that the capacity of current battery is the same. So unless you rooted your phone and wiped battery stats, you are not reaching the full potential of your battery. Unless you turn off your phone and let the hardware judge when the battery is full.

[Q] Tablet Turns Off after battery goes below 30%

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%.

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?

[Q] CM10 not charging past 90%

I'm running the 12/28 CM10 nightly, and I'm having an issue with charging my battery. When the phone is on, the battery charges normally to 90%, at which point the LED changes from red to green, indicating full charge. If I leave it plugged in, the phone continues to charge to 100. However, the battery doesn't really charge past 90 because once I begin to use it the charge drops really quickly down to 90. Similarly, if I restart the phone, even if it said 100 before, when it is on again it says 90. I have had this issue with previous CM10 nightlies as well. It is a software issue, because if I turn the phone off and charge it, it charges to 100.
Any ideas on how to fix this? Thanks!
This is a suggestion out of the blue but maybe try recalrubratung your battery

This is the intended bahavior. The type of battery used in phones last longest when they say between 80% and 20% of charged. So your phone will pull the maximum amount of power it can until it hits 90% then reduce power draw to a trickle charge.
The rapid drop is power is often the chip in the battery lying that it is fully charged when it is not. That is why you may see a rapid decline to 90% where your battery drain will go back to normal.
You might also see the phone telling you that it has 15% power then turning off. Upon reboot it will say it's at 0% or 1% that also is the battery trying to protect it self from damage.
This is a simplified explanation of how all phones work these days. The only difference you'll notice is how good the software is designed to lie to you about the power level. If it's good you won't notice these types of anomalies but they are still there.
Have you wiped battery stats?

Thanks for that informative answer. So I take it that means there would be no performance difference between turning my phone off, charging it, and then using it (with it saying 100%) vs leaving it on, charging it to 90% (green LED turns on) and then using it?

Battery stuck in deep discharge

Hi
I've been replacing my 3 years old battery in my Moto G LTE and I have an issue that new battery cant charge. I guess deep discharge protection was activated.
If phone is off and I connect charger, screen with 0% battery shows up. And it run in cycle = phone switch on, 0% screen, phone switch off, ....
And if I first turn the phone on, ROM is loaded, charging flash appears in notification area, but battery is still 0% or it flashes to 1%, but drops again to 0%.
Could anyone help?
Battery connector pins (on FFC) layout would be of great help as well.

Battery Just Dropped from 75% to 32%. In About Half an Hour.

According to the battery usage screen, about 15% of the battery has been used. And yet, it's in freefall. At 34% I got a low battery warning saying the battery would only last another three hours, even though it was dropping about 1% a minute.
Just randomly happened today. Left it unplugged overnight with Sleep as Android running, woke up to about 70% battery, started browsing on Chrome and Talon for Twitter, and 15 minutes later I had 20% battery. Plugged it in, got it back up to 75%, had to go out. Felt it get hot, checked, saw it was still dropping dramatically. Turned it off, left it to cool, turned it back on, and it continued dropping.
I had it turned off for a while to cool down after I'd plugged it in, as well.
Battery Usage does list Sleep as using 22% battery, but that's since the last full charge so I assume includes what it did overnight, which jives with having a percentage in the 70s when I awoke. Talon, Chrome, Facebook, TiBu, and a couple of other apps are listed as using 1-2% of the battery. That's it.
WTF is going on?

I think the battery might need to be replaced...after I charged my phone to 100% and then reboot, it will show 69% or 70% after the reboot -_-|. Also when the battery % drops down below 50%, my phone could switch off anytime - and then when I switch it on again, the battery is like 1%. I am using this phone as a backup just to receive messages so I don't mind it too much. If you use it as a main phone maybe it is time to upgrade to a newer model...the battery on regular Pixels were not so good even when new...
When the phone is off charge it to 100% then use it until it dies completly, then try to start it couple of times(it should just show a battery low icon or turn off while booting). Then charge it to 100% again while turned off.
This should pretty much reset the electronics in the phone. If it still does it replace the battery.
P.S.: Also look at the phone from the sides to see if you notice any glass poping (just in case the battery has started to expand)
