Optimus L9 Slow Charging Notification - LG Optimus L9 P760, P765, P768, P769

So my Optimus L9 P760 is about 4 months old. Whenever I'm charging the phone i get the "Slow Charging: Charging Slowly due to low Electrical Charge of TA/USB Connection". BUT I'm charging it with the wall charger..and I DO use the stock charger..

Try another outlet if u haven't already.... Do you get a notification saying its slow charging or it takes long time to charge the phone?.. if this is happening from the start then i think the charger is bad.

phones have built in system whereby it reduces the amount of draw from the charger if it "thinks" the connection is unstable or damaged. It seems quite common with the stock cable. Use another one or get it replaced.

Taking too much time to charge

Recently my gs2 is taking too much time to charge up. Yesterday from 10% to 85% took abt 5 to 6 hours. Previously it would do it to 100% in abt 3 hours.
Anyone else having this problem?
are you using it while charging?
i always turn of my s2 when charging, and it always takes me ~3h from about 15 to 100%

If you overcharge several times you will frye the battery. If you got root try BatteryCalibration http://market.android.com/details?id=com.nema.batterycalibration
Mine has never taken more than 3 hours from 0% to 100%, sounds like you need to calibrate the battery.

mine used to be like that but now for last three charges its taking that long.
How do you calibrate the battery?
Didnt think it was required as the batterystats.bin is regenerated at 100% charge.... I was told to calibrate by charging full while on then switch off and charge again to full, then on to full then use normally

How do you charge battery.. using charger or using USB port on computer? By some rule, if device sense data connection on USB it switch to 500maH charging levels. If there is not any data connection, it will charge as much as it can.

I use the main charger, very rarely i charge my phone using usb port.
today it took 4 hours to charge from 15% to 60%. then i disconnected it and downloaded a battery widget from the market and connected it again to the charger and it took abt 1.5h to 2h to charge from 55% to 100%. at the moments it looks ok. i will see how it goes on my next charge.

[Q] SGS2 won't start because low battery, won't charge because it can't start

Yes it sounds like a catch-22 and that's exactly what I think it is.
Yesterday my phone battery bailed on me. So I plug it in for a night and wake up to see it hasn't charged at all. It's still off and continually displaying the battery charging icon, after which it shows the Samsung Galaxy S2 logo, after which it dies. This goes on forever.
I've tried different outlets, also my computer's USB port, but to no avail. I have the impression that it wants to be on to charge, and since it does not have enough power to start, it won't charge. Seems like the amount of power from the charger suddenly isn't enough to start, or that the device tries to start before the battery can handle it.
This evening, after not trying anything for an entire day, I got it to show the CyanogenMod logo, but it got stuck on loading. So I took it out, wanted to go into the CWM to wipe some settings and have a clean installation, but then it bailed on me again.
Now I'm back in the endless charge-start-die loop. What can I do?
Hi,
I think your battery is messed up, buy a new battery. Or make it go into recovery mode. Or, go to your nearest Samsung Centre.

Do you have a multimeter to check the voltage of the battery?
Either you will need another phone that will accept the battery to charge it or your can charge the battery externally with a lithium charger (think Remote Control cars, planes, helis)
or ebay for a new battery.
---------- Post added at 08:20 PM ---------- Previous post was at 07:58 PM ----------
BTW Lithium batteries will die very quickly i not kept above the correct voltage. Li-Ion are charged in two stages. Constant current, and then constant voltage.
Constant current is to apply 500ma at around 3.7 or 4 volts per cell till the battery voltage gets to its upper limit depending on what battery chemistry you have. Then keeping the voltage at that limit, reduce the current continually till the battery is fully charged. As I do not know the max voltage for the cell, I will just assume that 3.5v will be a safe amount.
So to charge, simply apply 3.5 volts to the phone battery for a few minutes at a time, with a resistor or light bulb in between so the current is limited, then checking it back in your phone inbetween to see if it charges.
If you are confused at the major concepts here then just buy a new battery, to save breaking you or your phone.
I'm travelling around in Asia but the local market had a place that had proper equipment. I managed to fix the battery by charging it with an external one-fits-all charger (where you can put the positive and negative leads anywhere). After that I can just use the phone again and charge it normally.
If the phone didn't try to start but would just charge the battery when plugged into the mains, this would also have worked. Anyway, I had a new battery made (I'm in China so they just pack a random battery with some rubber to make the size fit into some stickers and that works). Funny thing is, it has 1900mAh, a lot more than the original battery, though being a lot smaller in size. I hope it will last...
thanks for the tips
Hi guys,
i have the same trouble of him, and i can share you that my wife and me just bought two galaxy s2 white from France...they are totally new (two weeks ago).
Here the bug i confirm, if we are out of battery, then to plug it in the official craddle of my car, with the official charger will power on automatically the phone, then it will loop in on---off--on--of, because not enough power to keep the phone charging.
I confirm that the only way to make the phone charging correctly is to plug it with the power socekt wall charger, by the car there is no way.
It seems the difference between the car charging and the house charging is that in the car when it is plugged the phone power on auto, in the house the phone charge without powering on the phone....
Is there a way to force in the car with the craddle to charge some minutes without the need to power on it auto ??
Your battery is not dead, or in France my wife and me got the similar issue and it is really not possilbe...
Hi,
have you tried to remove the battery from the phone for at least a couple of hours and then put the battery again and plug it?. I had the same issue and doing this I could charge the phone after a couple of tries. I hope you got luck with this.
I've tried it but it wouldn't work. A separate charger (charge outside the phone) did the trick, no more problems since then.

1 Cell lithium batteries like phone batteries are nominally 3.7v but their voltage depends on charge. They should generally be charged to a maximum of 4.2V, and not discharged below 3.3V/3V, depending on who you ask. You don't want to get it wrong though - look up what happens if you overcharge a lithium battery on youtube!
Same Problem Battery Logo Boot Loop
Has this problem been solved ?
I have the same Battery Logo Boot Loop
I have several batteries, and a separate charger ... batteries at 100%
The problem occurred while phone was in use, connected to wall charger, and had reached 100% .
I continued to use the phone while plugged into charger.
Phone shut down with a Battery Logo showing only a thin green line at bottom.
I turned phone off and swapped in a hot battery, but phone would not turn on.
Stays totally black screen, will not enter Download mode or Recovery mode.
With charger plugged in it will go into the Battery Logo Boot Loop.
The blue light next to the power button flashes, the Battery Logo appears for a few seconds then screen goes black and cycle repeats.
Any help will be appreciated.
Thanks

Probably...
If you have another battery, change and check if it is still draining. If so, I'm afraid main borad is damaged and I can't say anything about how to fix it. If it stops draining, congrats! It means you fixed it!

Go to a service store. More then sure when you dropped the phone some weldings got cut out.

How do I know if phone is fast charging?

My previous phone was saying on the lock screen "Fast charging" and I was able to see two lightnings on battery icon in a same time so I knew immediately when fast charging was engaged.
How is Nokia 7.1 ?
It will display rapid charging.
Well, I don't see rapid charging anywhere using original charger

My bad that's weird mines displays rapid changing under the fingerprint symbol on Lockscreen
Ok I got it as well, it doesn't say rapid charging all the time though. Thanks for the hint
is the original charger fast charger?
When you plug the charger it takes some time for the phone to detects if it is fast charging. Then it displays charging rapidly. And after a certain percent of battery charged it quit the rapid charging i thing (50-60% i think but i could be wrong). As of my knowledge of how lithium battery is charged this is usually done to prevent overcharging and popping the battery as a popcorn. I am not sure if this is exactly the case just an assumption based on my very few times observing the charging (im new with the phone). Never payed much of attention on that on my previous quick/fast/rapid or whatever charging phones.

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Realme X2 Pro can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
Quick isn't the word. It's amazing seeing how fast it charges.
Can it be charged with a 5 volt charger?
I think I have a problem with fast charging.
Yesterday while the phone was charging, electricity in my house was shutted down. When it came back, I can see than now, I charge 1 % on 35 seconds, instead of 20 sec before.
Could it have the battery damaged ? I doubt so, buty it's strange.
I tried when battery was 82%
Maybe it's quicker when battery is low ?
What's your thoughts about this situation ?
Thanks !
Edit : Okay, after 85% it slows down, but before it's okay

Yeah it slows down towards the end I'll go from 0-99 in 28-30 min then takes some time sometimes to get the last 1%. Battery life is also incredibly good.

Yeah battery life is outstanding..
Anyway, I have a little weird thing :
This battery monitor stats shows me different SOT than GSAMBatteryMonitor.
GSAM shows 2 hours more (wich I think wrong), and this delay grows while battery dercreases.
Do you have this app showing the same stats than colorOS battery monitor ?

Greetings.
I got my X2 Pro about 2 days ago. Charging speed is even better than advertised, as it takes less than 30 minutes to reach full charge. But phone usually gets too hot when fast charging. Do I experience this problem alone or do you guys too? Kinda worried about battery health in the long run if it gets too hot everytime I charge it.
Thanks before

Same thing here, so I don't charge more than 40 - 45% at a time.
If my battery is below 50%, I charge in 2 times with a 10 min pause.
Doing sop, you don't reach hoptter than 33 degrees instead of 38+
I can't seem to get a decent standard charging from 5V 2A chargers or Powerbanks, even a QC3 Powerbank only delivers 0,9-1A.
I only get about 900mA according to the Ampere-App. {On the contrary, I even get 1,8A from the original wall plug at 80% SoC).
Do you also struggle?

Same here. I used a 9V 2A charger, and it won't go more than 1100mA.
I wonder if this is a detection error from the apps. I think they don't consider the dual battery layout and only display half of the true value.
The error that the app "charger tester" shows let's me think this or does support my theory.
All apps seem to not be able to show the correct current flow because of the dual-batteries.
I found the engingeering mode and can confirm that the phone charges with 5V 2A on dumb chargers.
And also supports QC 18W with 9V 2A
As well as the Oneplus 20W Dash charger with 5V 4A.

Super VOOC (and also VOOC) have their own protocol of charging mechanism. It's not the same with other quick charge method like Quick Charge 3.0.
You will not have VOOC charging if you are not using right adapter and right cable. You try use Super VOOC charge with other USB cable, VOOC charging will not work.
So when you using other adapter or cable, you'll got standard 5V charging max 2A.
