I have one question abought oneplus one. I notice that when phone is charged to 100% ampere app says 0 mA. Is that normal? when the phone is charging from 0-100% I have normal value only when phone reach 100% app say 0%. On my second phone ampere app say "charged" when phone reach 100%. Is thos normal on oneplus? i have 64GB model and stock rom.
Charging
Once your phone reaches 100%, it goes into a low power mode, needing little to no power to keep it at full.
ok. app confused me because the value is 0mA when phone is 100%. ;(

My Fuze doesn't charge when connected to charger or connected to sync cable, I notice that when i connect to the charger and leave for a while the battery percentage remains the same, if i reset the phone the battery level will show a higher percentage, number would decrease but never would it increase when charger is plugged, to see the increased figure i have to reset the phone. For example, if my battery power is 1% and i plug the charger to the phone, it will remain at 1% the battery icon wont even come on, nor does the LED indicator, If i reset the phone then i would see say 20%, if i reset right away then it would show eaither a higher figer like 37% or a lower figure like 11%. I really dont whats wrong.
If we leave the battery display.
Could you confirm whether your battery is getting charged or not. I mean charger or connector is working.
How old is your battery? Could it have been over discharged?

Yes the battery is getting charge, it just doesn't show the percentage increase nor does it show the fork like icon when the charger is connected, and its doesnt sync. However The battery does get charge.

I have two batteries, one that i normally use, which is abt a year old. the other that i charge as a spare and carry with me every once in a while is abt 6 months old, and the i have tried them both,i get the same results.
My phone charges steadily till around 75% to 80%. After that charging speed becomes very slow. It takes almost 2 hours to reach 100% from 80%. Also the charge value remains steady at any random level for a long time and then suddenly jumps 3-4% in one second. If I reboot the phone anytime when the charge is more than 80%, then on rebooting the phone suddenly shows 100% charge!
I tried various battery monitoring apps from the market and all report battery condition to be 'good'. I have done the 'full charge - full discharge' cycle many times. Is this how all HTC Sensation's charge?
MY XE only goes to 99%. Tried to wipe battery stats but still only up to 99%.
Do you charge while connected to a computer or directly from the socket? Both methods behave very different in my experience. You should try the other one, to see what it does.
Edit: Also, what voltage do you end up with after charging to 100%?

I charge from the ac mains socket. Voltage I will have to see. I havent given it particular attention but I will check and report back.
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?
Hello,
I bought a second hand S6, and after some while I noticed a battery issue.
While discharging, everyting is normal until about 11-12%, when it drops to 5% and then continues like normal, 4-3-2-1-shutdown.
If I put the charger even for a second in any percentage below 5% it jumps to 8-9% , and then contunues the discharge from there without missing capacity.
If again I continue to charge without disconnecting, if goes lets say from 1% to 8% instantly and then continues charging like normal.
Is this normal for an old phone? Or can I fix it somehow?
I had never noticed anything like that in any of my android phones before, ever 3 years old.
I have already deleted battery stats, and performed 2-3 times full charge/discharge cycles, without results
The ROM is original 6.0.1 rooted.
Hello,
Tried at 100% and stayed at 100%
Should I try at 10% or 1% ?

It happens for me too. It's just Samsung's failure. Sometimes my battery jumps %1 to %17 when i plug the charger.
To be honest, you can't do anything about it.
I did the proceadure at 14% it dropped to 0% after some seconds and then shut down.
I charged it OFF but when it reached 95% went to 100% in seconds.
When I unplug at 100% and wait 5 minutes (always OFF) at next connection to charger showed 95%.
So it took me 1 hour of intermitted charges to reach 100% and stay there.
We'll see what happens next. I'll keep you updated.
Hi everyone, im having a problem with this phone:
1- Charging the phone never reach 100% in one charge, it always stops charing at a random number, for example 70%, no matter how much time i let the phone charging it never goes past that. The solution is unplug and plug again, then it reaches 100%.
2- The number 1 is not a big deal but this is. The phone automatically turn off at a random number again, let say 66%, and i cant turn it on. If i connect the phone to the charger it says 0% battery. Is not like the % freezes at 66% and i use it all day and then turn off. For example, i have the phone at 100%, i start using it and i see the % going down like normal and after an hour or two of using it suddenly turn off and im not able to turn it on again because the battery is at 0%.
I tried:
Hard reset, wiping cache, data.
Hard reset, wiping cache, data and installing the latest stock rom.
New battery.
Different charger.
I have no idea what else to try, anyone have a clue?
Thanks!
I think the battery is broken, also had the problem. Then I bought me one on Ebay for 9,99€ and now everything is good again.
Try using a -known- good cable and charger.
Make sure the port contacts are clean and debris free. Always charge with screen off.
You can also try powering the phone off and see if this alters its charging pattern.
My best guess...
When it auto shuts down again pull the battery and measure its actual voltage to determine if it's at about 6%.
If actual voltage indicates it's at 6%* may be a bad battery (limited capacity) or a hardware failure (shutting the charge cycle down prematurely).
If battery actually has 20% or higher when the phone shuts down) it indicates a hardware failure in the phone.
If battery temp exceeds about 102°F during charging the phone will abort the charge; make sure this isn't the cause. A hot charging battery in a cool room could indicate a battery or hardware failure. If battery temp exceeds 107°F or so in operation the phone may also auto shutdown.
Excessive cold (>32°F) will effect battery capacity severely.
Don't charge a cold Li battery (under 70°F).
Never charge if at or below freezing**.
Li's like a charge temp range of 80-95°F
They prefer frequent, short mid range charge cycles (40-65%) vs topping them off beyond 80%
*hunt down the voltage/% charge for this battery
**can cause Li plating which will permanently degrade the cell
