Hi, I would like to share my experience on my L9 P760 (v10a unbranded form TIM Italy with root) about the following issues using the original LG charger:
1) I never power off my L9 and usually I recharged it in the night (not in airplane mode) while I am sleeping, so I plug the charger at 23:00 and I detach it at 7.00 with a charge variable from 94/95% to 100%.
2) The first hour after dectached from the charger, the phone drain battery very fast, tipically 7/8-10% in about 1 hour (also by doing absolutely nothing on phone), next it gets a quite normal battery consumption.
Assuming these 2 conditions, I always have used the phone in the same way and basically with the same set of apps used and installed. I leave all sensors always on, the 3g, the wifi, the bluetooth connection always on with a full synchronization for two google accounts. The main activities I usually perform on the phone are check the mail with GMail, read a lot of news with Currents, a moderate usage of Facebook and Twitter and watching some video on YouTube. In these typical scenario usage, the maximum performance I obtained from battery was about 28 hours with about 3 hours of active screen usage. Quite good but...
Accidentally, I discovered that charging the phone with another charger (not LG, in my case an Asus charger for the tablet TF101G but I think it could work by using any charger with a different volatage output respect to original) give me an incredible improvement on battery life. Not only when now I detach the phone is ALWAYS at 100% but also the fast battery drain observed in the first hour is gone. Now with the same usage scenario described above yesterday I have obtained 44 hours of usage (with a residual charge of 14%) and more than 4 hours anf half of active screen usage. I am quite sure that this behaviour depends on the charger because I repeated the entire cicle of charge-use_the_phone-charge for three times and I always obtained these consistent results. Next I tried to charge again the phone with original LG charger and I have again the same set of issues reported above.
I attach the screenshot of battery usage this morning just to show you what I said.
Anyone has found a similar behaviour on his L9?
hm more should try and post feedback, i dont have a second charger and i also notice the same battery drainage with loosing fast the first 7-10% after charging and phone not full when i wake up in the morning.
Is there possible a battery damage by using an other charger? this seems like a charger thing, lg to low the costs of production in this model has cutted down the quality in every peripheral of the phone, charger cable headphones etc

For what I know (please someone correct me if I am wrong) it should not be a problem. I think you can use without problems any charger which have a maximum output greater than the required input power of the phone (the power in excess will not not be used).

lolz, :laugh: replace your original LG Charger, must be faulty. You just said its unbranded TIM Italy.
I get similar good result with original charger. My battery lasts more than 35 hours with business use and more than 40 hours after moderate use. Or may be P765 in India got good quality chargers than other countries.
REASON FOR SLOW CHARGING: LG EXPLAINS IN WHICH CONDITIONS L9 CHARGES TOO SLOW HERE ON THIS PAGE . In your case your Networks (3G, BT, etc) are always on, that means CPU is always working at some extent and L9's built-in feature slows your charging to avoid OVERHEAT problem explained on this page. LG have restricted heavy CPU usage and Charging at the same time to avoid device malfunction.
EDIT: Any technical person will tell you overnight charging is bad for battery and phone as it creates too much heat and that damages battery. And yes, My phone gets 100% in around 1-3 hours. And when you say you need to charge overnight and its still 94% sometimes, then dude you have slow charging problem with your charger.
cmahendra, first of all, I want to thank you for the precious tips and solutions you give us in the forum. :good:
Let me clarify some points:
My phone was originally a branded TIM next I unbranded it and transformed into a kind of european V10A (I said "kind of" because I flashed european firmware but the software version shows p76010a-222-01 differently from a real european phone. It seems that this code is computed by using also the IMEI.)

This explanation given here can not apply to my situation. In the night the phone basically is always in deep sleep, so there should not been overheating problem, so the charger should work at its full power.
I even don't think that my charger is faulty because: 1) this problem (of not completely charge the phone after a night) is common to a lot of other L9 P760 users (as reported in other italian forums and applied even to branded or unbranded europoean firmware). 2) I can confirm you that if I charge the phone during the day it reaches the 100% of charge in about 2, 2-5 hours but when I unplug it it has always a very fast battery drain in the 1st hour. Some days ago, with original LG charger, I discovered that in the night, ithe battery has a continuos fluctuation from 100% to 95/94% as showed here:
so this is probably is the main reason why in the morning when you unplug the phone you obtain a variable charge of the battery.
I think it is a strange behaviour which is related to some bugs in LG firmware on P760, at least in v10a. I even don't know if this problem has been fixed in the last v10h (and possibly someone can confirm us). Anyway, for now, I will be remain to v10a just because I need root for some applications.

Input:100-240V ~0.5A
Output:5Vdc/2A or 15Vdc/1.2A
about the chargers... you can use any charger that has 5.5 DCV output. The trick for the slow charging is the current, I charge my L3 with original lg charger with 0.7A (700mA) and it charges from 0 to 100 in 3 hours max, so try another charger that has more output current

I checked the default LG charger and it has these specs:
Input:100-240V ~0.2A
Output:5Vdc/0.85A
So the original LG charger has lower ampere in input and output (less than half), are we sure it's not going to damage phone?

I read on several other forums that should not be a problem. Example:
http://forums.androidcentral.com/ve...se-tablets-2a-usb-charger-charge-rezound.html
Anyway, next days I want to try with another less powerful charger. I have also noted that the phone while charging is not overheating, so it could be a good signal that all is ok.
Tonight, I also want to use "Battery Monitor Widget" to get useful statistics about temperature and power absorption while charging the phone.
I will let you know something soon.
I've got the same problem. I charge full my L9 and when I detach my mobile from the charger the battery starts to drain fast even if I don't use it or unblock the device. Then, when the battery reachs about 80% of battery, the consumption stabilizes quickly. In general the battery life is quite good but I expected more of a large duration battery.
The strange thing is that when the baterry is low, (more or less at 25%) it drains so much slower compared to when I unplug the charger. Any more suggestion? I've bought it 5 days ago and I've charged it 3 times.
Thanks for your help and sorry with my english, I'm spanish
It was once posted on xda portal that charging from a pc (usb port) although it's slow, it makes the battery last longer, because of low voltage, so using a charger that passes less voltage is always better, but the charging process is longer.

Cool. The thing is I turn my PC off at night so I use the travel adapter included with the phone. I have noticed my battery always starts at 99% instead of 100% and seems to drain fast to 95%, but afterward the battery life is good.
I turn off my wireless most of the time because I saw wlan_rx_wake was causing an unholy amount of wakelocks due to some dynamic IP crap. I also turn on airplane mode at night because I want to sleep. I also ran the T-Mobile bloatware disabling script by LG here. I have no idea how much of a difference that made. However, I left location services and sync on because I noticed very little difference. I play about 15 minutes of games and use the screen for about another 105 minutes everyday. My battery drains about 40% in 30 hours. So I can get two or three days of charge before I have to recharge.
Here's my current power breakdown after 32 hours, according to GSam Battery Monitor:
Screen - 64.1% (Medium brightness, 50%)
App Usage - 25.0% (Android System - 5.5%, Kernel [Android OS] 4%, Game 1 - 2.5%, Kii Keyboard - 2.5%, Game 2 - 2.4%, Live Wallpaper 1.0%)
Phone Radio - 10.1%
So I have some news...
Relative to temperature while using the tablet charger, I can confirm that the temperature reached by the phone while charging is not high , like when you use the phone for normal activities (about 24-25 °C). See yourself the attached image.
I have also try to use another charger (in this case a Sony charger of the Xperia of my wife) which incidentally has the same specs of the original Lg charger: output:5Vdc/0.85A. I expected the same behaviour as with original charger (so with the same issues) but I obtained a correct charge at the end (100%) and no continuos fluctuation from 100% to 95/94% as reported with original charger (check the attached image).
So my conclusion is that there is something that does not work in the original charger. The strange thing is that a lot of us have these problems so I don't' know if this a build problem of the charger or a set of flawed transformers...

I don't know the specs of the charger of Toshiba but you can use any charger which has an output of 5Vdc. The amperage of original L9 charger is 0.85A so if you use a charger with more amperage, you will charge your phone faster with higher temperature for battery, with less amperage the phone will charge slower but with a lower temperature for battery (in general the high temperature is a known enemy of the health of a battery). My tip is that you should use a charger with the specs similar to the original LG charger.
I tried using the USB charger on my laptop instead and I did notice my first 5% of battery drains much slower than before.
The L9 has a good standby life. By running the LG bloatware disable script and disabling specific apps myself, I was able to draw less than 1% on standby with 15 minutes of active screen usage and wireless turned off. With airplane mode turned on at night, the phone can last even longer.
However, the battery drains very fast with active screen use and wireless turned on.
Can you all please post what is your battery's voltage when it is at full charge BEFORE you unplug the charger??
(Most battery software can give you voltage reading. I use battery spy.
Thank you!!

Thank you tizfa. This is the same terminal voltage I got in my P769. I can only take it that the reporting is accurate. More than 4.2V will damage li-po battery in no time.
Just a little process of elimination on the overheating issues.
To be clear: I don't have the issue of continuous overheating when nothing seems active.
I do have a problem with it overheating when playing games or streaming.
Also the overheating and drain is so bad that the battery will drain even while plugged in during this time.
so, do you have the same problem?
To keep the results consistent please test with this scenario:
Play Asphalt 7 until it heats up noticeably. Then plug it in and note your charge level. Now play some more and see if your battery drains.
I think the overheating and faster battery drain is normal.
For example if the CPU and GPU need 10W to render such intensive game at 24fps and your charger can supply only 5W (5 Volts * 1 Amps) then you have battery drain, not charge.
Try charging your phone with charger that can supply 2A (usually phone chargers are 1A), then you might actually charge your phone while playing this lovely game.
The whole point of this poll is to determine what is"normal" so we don't have to come up with theories.
BTW: I have never seen this happen on an iPhone or Android as manufacturers usually engineer their components to accommodate.
I haven't played Asphalt, but some other games, and yes, the phone overheated, there was no battery drain, BUT the battery was charging significantly slower.
Using 3rd party navigation apps like "Navigation 3D" and "GPS Voice Navigation" overheat a lot the phone and the battery drains in a couple of hours from full charge.
Also with my 500mAh car charger the phone drains with these apps.
Overheating for me is when the phone gets so hot that it will shutdown to prevent damage.. or is damaged...
Did your phone gets hot or is it really overheating???
Phones can get really hot when you combine some of this things:
-Charge
-use wifi
-use heavy apps (navigation) or gaming
-stream or watch videos
-have your screen on full brightness
-use it in heavy direct sunlight (like in the car)
the more things you combine simultaneously the hotter your phone will get...

According to the poll so far: 40% of phones don't overheat and 20% don't have the voltage drain.
If 100% of phones behaved the the same then it would be easy to accept that this is normal behavior.
But I'll keep sending mine back until I get one that works.
the term overheating implies that the device stop functioning
running hot would be a less confusing and more appropriate terms. All electronic devices run hot under prolonged load, laptops, tablets, ipods, it's par for the course.
Obviously I didn't mean that malfunctioning is normal. I agree "Running hot" is more appropriate term..

What I'm trying to do is provide a baseline acceptable level so we know what overheating is.
I already know that something is wrong when the provided charger cannot charge the phone and the and the heat level is uncomfortable.
Overheating is: anything that is beyond the designed run temperature threshold -which we don't know but can discern through collaboration.
Well through logical deduction on could come to the following conclusion. Phone does not charge with provided charger, phone get uncomfortably warm, there is only one thing in the phone that can generate that heat and that is the battery. It is a Lithium Polymer battery and they are notorious in any device for having workmanship issues. Since it won't charge that points to the battery even more. I would take it in and have them change the battery since it is a major undertaking for a regular user. Or just exchange the device. Just tell them you afraid it is going to cause a fire.
My HOX+ battery has been acting strange for some time and I decided to monitor the battery drain/charge.
I've noticed a few problems:
1. From about 87-88% upwards, it doesn't seem to draw power anymore, it just goes up to 100%.
View attachment 2657437
2. From about 30% downwards, the drain % spikes up and quickly goes to 0%. When the battery reaches 30%, I know I can't do anything anymore or else it will die in ~10 minutes, if not less.
I dont know what causes the increase in power drain, I only had the screen turned on and even put the phone in airplane mode. You can see that before this starts happening, the battery drain was pretty stable around 400-500 mA, while watching HD Youtube videos over wi-fi (which also means that other apps were syncing; i have a few messaging apps and a few email accounts with sync on).
View attachment 2657439
View attachment 2657443
3. Watching a movie or browsing some websites with Chrome browser will drain more power than the phone can draw from the wall charger. A full charge takes about 4 hours, even with wi-fi off.
I've tried charging with different HTC chargers and different HTC/standard USB cables, I didn't notice any difference. I don't get it, is the HOX+ really that bad, power-wise?
Please let me know if I can provide other logs or details.
I have the HOX+ international version, with the following specs:
CPU Tegra3 1.7mhz, 1GB RAM, 64GB storage
Android 4.2.2
HTC Sense 5.0
not rooted, stock everything
HTC SDK API level 5.41
Is my battery faulty? Is it a software issue? The app is not reporting correct values? Is there anything to do?

When your battery level is above 80%, the charger changes the way of battery charging. I'm not an expert about energy, so I can't say what exactly it does, but if you google around about chargers, you will know it .
Hi everybody
I've got a major battery issue with my three year old Nexus 10.
The battery indicator shows something around 75%, drops to 0 in a split second, switches in energy saving mode (notification and navigation bar are turning red) while it shuts down.
To verify I made an Automate Flow saves the battery charge every second to a text file. Result:
Code:
82,82,82,81,81,81,81,[...],73,73,73,73,0,0,0,0,0 EOF
Okay, it thought to myself, after three years the battery is broken. So I bought a replacement battery (Samsung original) and replaced it - but nothing changed.
To clear all old stats (and running Android 6.0.1) I wiped everything TWRP offered and installed CM13 - but nothing changed.
Now my only guess is, that there's some EPROM (or other memory hardware) that stores battery stats.
Can you, dear forum, help me fixing that issue?
No one?
Has anyone of you guys changed the manta battery, yet?
Same thing after OTA upgrade in D6563
I'm facing the same problem here with my d6563, after the MM OTA update i started to face quick vertical battery drop, but we're not the only ones, some users are reporting this issue in a lot of devices, some of them after update, some others after rooting, some of them just after some apps update, and the thing is that nothing seems to work, some users claim to have solved the issue, but they are just talking to fast, because the problem comes back the same day, they just think taht the battery data is accurate but then the drop accurs, si, i'm starting a new thread listing all the solutions tghat senior members have recomended and failed in order to track this problem to his roots once in for all, it's been happening since kitkat at y has come worse since marshmallow
keep in touch to see what we can figure out about this.
Battery _stats_ issue
I had, ummm, similar issues with my TCL S720 (in less degree) and now with TCL M2U (TCL Meme da 3N M2U AKA Alcatel Flash+) phones.
TCL M2U has 3500mAh battery capacity.
After full charge it discharge normally to ~40%. Behind 40% it is discharged to 1% for a few minutes and shuts off!
If then I charge it again to 100% then it eats about its full capacity (~3500mAh) - checked with Keweisi USB Doctor and shows 100% charge, but discharges to 40% again.
On other firmware there is similar effect but for 30% level or 15% level, it depends on firmware.
I think that the battery is OK but the charge percentage display is wrong.
Another strange thing is when I see the charge level using Ampere app. It shows i.e. 50% battery level and 3.762V voltage on the battery. Then I plug it in charger. For a short time the voltage rises to 3.8V and more but the battery level is lowered to 45%! Also if I charge the phone from discharged state then the battery level is 1% for the long time, then it quickly raise to ~30% and then shows charge process normally (almost linear). The USB Doctor show the charge process smooth almost all time (from stronger current to weaker).
So I join to the 1st post question: where is the battery's _real_ voltage level data?
Hi, I'm coming from an SM-930F and now have a SM-965F. I'm experiencing a strange charging behavior. I became aware of this when noticing that the S9 plus when connected to my Aukey QC 3.0 charger in my car via the OEM cable (screen on and GPS active) can only hold, but not increase the battery level. This was completely different with my S7 (same charger) which achieved an increase in battery level of 30% per hour, all other things equal. I now did some tests with a plug power meter and found that the charging current goes down immediately when the screen is switched on by roughly 75%. The charging power decreases from 6-7 W to 1.5 W. Please note that this is the gross current/power flowing from the wall socket to the device. With the energy consumption of the display, the net current flowing into the battery is negligible which explains the observation above. Interestingly, the effect is also present with the Qi charger, but to a much lesser extent (only 20% reduction of charging current with screen on). The S7 does not behave this way.
Has anybody observed similar effects or could check with his/her own device? Is this an intended behavior? Does this mean that - effectively - the S9 plus cannot be used while charging?
Best regards
Christoph
I have a USB multimeter and have checked several phones of mine.
This behavior is inherent to Qualcomm Quick Charge. I came to the S9+ from a Droid Turbo 2, both exhibited the same behavior.
Also i've never seen voltage spike above 9V, even though it's supposed to go up to (in theory) 12v (QC2.0)
Samsung support told me that this was not normal. I sent the device to them now. We'll see whether this will make a difference.

1.5W is waayy too low for modern smartphone, I'm averaging about 5W with the regular "cable charging" status.
I'm having issues trying to trigger the fast charging mode on my S9+ with the variety of QC2/3 capable chargers that I have laying around. Just bought a voltmeter to do more testing to see what's going on with these chargers.
I don't even get consistent result using Samsung's charger and cable, so I'm wondering if my port is jacked.
Samsung phones don't fast charge when the screen is on, but it shouldn't drop as much as you're seeing. It should work pretty much as the S7 did.
Hi folks,
I still have an issue with the charging behavior of my S9+ and, as time has gone by and I have collected some more information, I am seeking your advice again.
My problem is that cable chargin while screen is on is more or less impossible.
This is not about fast charging not working. I am aware that fast charging is not fully operational while screen is on.
But 9 out of 10 times my phone does not charge at all while screen is on when connected by cable.
However:
- Charging on QI charger with screen on is working.
- Cable charging with screen off (even with always on display switched on) is working normally (not superfast, but roughly 30% per hour which is ok for me)
- Even with screen on, status bar notification says that fast charging is active and gives "normal" estimated charging times. But the battery level won't increase over time (or only with very low rates).
I already tried various chargers and cables without any effect.
I resetted the phone for several times. I verified that the behavior described above also occurs with a plain phone without any Google or Samsung account or any other apps than stock installed.
Brightness of screen does not really matter (with lowest level you might get very slow (1% per hour) increase in battery life, with highest level it is closer to -1%/h).
I even sent it to the support where they told me they could verify and fix the problem --> without any effect.
I changed the phone. Unfortunately, the new one first seemed to work flawlessly, but showed the same behavior after some cycles.
Interestingly, sometimes (1 out of 10) cable charging with screen on is working at least somehow. Some days ago, I could increase batterery level by roughly 10% within one hour. But I could not repeat that.
I attach screenshots of GSam Battery Monitor which show that charging rate goes down as soon as display is switched on.
Do you have any ideas? How is your phones charging behavior while screen is on?
Best regards,
Christoph
I'm just speculating on this but I always was under the assumption it turns down the charging rate due to heat, having the screen on, GPS going, etc heats the phone. The newer models seem to be more sensitive to it and throttle back faster.
My dock sits on up on the windshield and it doesn't take much when it's sunny out for the phone to stop charging all together, it overheats when running GPS, screen on and the sun is hitting it. I need to find a new mount to move it lower down on the dash...
Thanks for your reply. I also suspected that temperature could play a role here. But I have not been able to verify that yet. Attached you'll find also battery temperature for the charging cycle shown in my previous post. I also let sit my phone in the fridge for a couple of hours before charging without any significant effect.
On the other hand, I find charging rate to be lower on hot, sunny days. Today, with cloudy sky, I could increase battery level by 4% during my 30 minutes commuting time. Thus, if there is a relationship with battery temperature, it's not a simple linear one...
I had to move my phone mount recently because of some changes I made to my car, previously it sat in front of the AC vent and I didn't have issues, now it's not and that sucker overheats and stops charging in no time when it's sunny out. If you can position it where a vent is blowing cold air on it, it should help.
Unfortunately it's already sitting there...
Hi,
I have a charger with a qualcomm QC 3.0 port and other regular 9V 2A ports, so I have the same problem when my phone is connected to QC port, but for some reason it's charging normally when connected to the regular ports.
My phone is the european exynos version.
Interesting, mine is the exynos version, too. I'll try to test a regular port, too.
And also good to know, that I'm not the only one with similar problems...
