OK, so here's the deal:
Had my S2 for about a month now, and apart from the battery draining faster then would be nice this phone is an absolute killer cool thing
But now here is the issue:
In the month I had this phone I had 3 occasions of the battery draining to empty while it is ON the original wall-charger. Do describe the most recent case:
Im at work, and I see the battery could use some charging soon. So I plug it in, leave it for a bit with screen turned off. A bit later I pick it up whilst still in charger to do some minour things on it. After a few minutes (phone very hot in mean time, but known issue) it gives me a pop-up that I need to plug in the charger which it is already on. So I check my Juice Plotter and notice that indeed it sees it is on the charger, but the line which shows you the level your battery is charged is coloured red and has been dropping just as fast as before I plugged it in. Near critically empty?
So to check if some app is draining the juice in the background i closes all running services and apps and leave it for a moment. I check: only about 1 percent charge left? O - M - G.
So i did what I did in previous 2 cases: Turn phone off to get it charged to at least about 20% (how nice that someone/something else is forcing me to be unreachable by phone ). When I turn it back on at that point, I check juiceplotter first... No real changes or battery charging for first maybe 5 minutes (it just stays at a flatline level) and then finally it starts charging again slowly but steadily.
What's the deal here?
Since 1st time this happened i started keeping my home screen as clean as possible and such to be as energy-efficient as possible. Barely use screen-brightness (by the way the auto-brightness sucks). On 1st page of homescreen I have the Juice plotter widget showing me battery depletion / battery charge time levels. Funny that in the explained problem cases you can actually see the time till charged getting longer and longer by the minute :S
Hi, I've been noticing a few problems with the TP prime.. let me start with my battery issue.
1) I noticed that when TP is charging from wall socket through dock, it will charge to full 100% for both, then the main will discharge its battery even while it is still plugged in. Did anyone else notice this? (as if the tablet cuts the outlet power after a full charge and uses its battery while still at "full" status -- down to about 95% battery or so)
2) In YouTube app, if trying to search using the Youtube's own search line at the screen after watching a video, dock's space bar functions as "page down" instead of a spacebar..
3) The diagonal flickering screen from top left corner to bottom right appears when I press recent apps button, with more than about 5 recent apps listed. The flickering stops when I have less apps.
My main concern is the battery issue.. I don't understand why the main battery drains when it is plugged in, only to be recharged and so on. I will leave my TP in the outlet throughout the entire day today and will observe graphs myself, but I wanted to see if anyone out there has similar problems. Thanks guys!

AFAIK the battery policy is different that that of the OG transformer. It should discharge to about 70% then start charging back up (probs the optimal charge rate for the batterys)
1)
It is not possible to trickle charge lithium ion batteries. So when the battery reaches 100% capacity the charging stops for a while and then starts again.
I think the reason why you see it not plugged might be due to some modification of the battery MMI. The original transformer might have shown 100% after being fully charged and plugged in, regardless of it being in a discharge period.
I would call it a none issue.
2) Mine does that too. Might be a clash with the browser engine in the youtube app. Most browsers scrolls when you hit the space bar.
3) I haven't seen this.
Hm.. interesting. Thank you for your answer for #1. I left my prime plugged in the entire day today (24 hrs) and I saw the trend of it draining and recharging and draining on itself lol. And yeah I still have that flickering diagonal screen when I open the recent apps--hope the new OTA fixes that issue..
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 also posted a thread about this problem, so it's not just me. I have a v10a brand vodafone.
http://forum.xda-developers.com/showthread.php?t=2116956
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!!

Hey guys what's this means?!
My battery is falling down automatically with no use!
See
I am wondering about this faulty behavior because i am in 510 firmware with no extra apps installed
I had this issue with. 475 too.
Help me please if this is a hardware issue send it back for second time in this week!
Instead of i charged this phone two time totally when i am bought it.first time faulty drainage happened yesterday when i played some game and battery went to 80% then i went to sleep for half an hour and when i turn the phone on again,noticed to battery is lost to 30%!
Sent from my C6802 using Tapatalk 2
I noticed a faulty battery usage indicator on mine.
It happened 2 or 3 times, when I plugged the USB cable to the phone (other end connected to a PC or charger) and the phone LED immediately turned green and the battery indicator jumped from 60% to 100%.
Nothing happens if I re-plug the charging cable, the phone keeps saying it's fully charged. Even powering off doesn't help.
The 100% power won't drain faster but I noticed that when it goes to 30% the phone will shutdown because no more juice is inside the battery and the indicator will go back to less than 10% after re-plugging the power cord.

In your case i think that's better try it with latest firmware.maybe solved.
But for me,the story is different,unfortunately!
another Q has been busy in my mind. Why sony didn't used a better charger for this phone?! Charger has only 1.5 mA output power! For test, i am charging the phone now with s IV charger (2mA)

Higher mA output is not necessarily better.
Taking more time to charge is more gentler on your battery.
Pumping up the mAh to 2 or higher will improve the charging time, but the number of total cycle charges (i.e. life span of your battery) will go down and suffer.
Anyway, 3 hrs from empty to full is normal, right? Anything quicker is a quickcharger.

Good thing you included screenshots from GSAM, so that we have something to go on now.
Remaining (Av.use) 18:51
This tells me that you once had a phone that was efficient, so from the day you realised this drop in performance, scrutinize what settings have changed (inc app installation)
Remaining (last 15 min usage) 5:47
IF u continue using your device in the way you have done in the last 15 mins, you have under 6 hours left of battery power.
In the 15% discharge since fully charged (and since when GSAM started taking this data on your screenshot), 62.9% of power was used by screen.
Some conclusions can be drawn here.
As you mention, you were probably playing some games during the 4hrs and 11min the phone was turned on(from when it was fully charged and then unplugged), very likely during the latter stages than earlier from when the phone was fully charged.
I see your screen is set on DIM, and that it has been active for nearly one hour. Your display was on for 25% of the time since full charge, and that has only used up 15% of battery.
Whether it is games or video playback, screen will be on, and looking at the data there is nothing faulty. In another words, set at dim, 7 hours or so of continuous display on sounds about right..(1 hr already used plus 5:47 expected left)
Now, if your complaint is that if you turned your phone screen off and left it that way for a few hours, came back, then found massive power drain, again, a few conclusions can be taken.
It is a shame there is no screenshot of the app usage form the exact same period. But, If you left the game app open in the background, it is possible that power is drawn still, possibly if your phone is not sleeping properly. In another words, CPU usage for game is there even when not used.
Do you have stamina mode on?
Conclusion... Form GSAM data, there is nothing wrong.
Looking at the first screen capture in OP, as you say, drain happened when phone was not awake, and screen off. I can only conclude that there was an app(s) open at the time which had been still running. If the app(s) is not closed or hibernated properly, it can happen.
If your phone felt hot at that time, it confirms CPU usage.In another words something was left open. If it was cold, even though the phone had been off for a while, then it could be faulty battery calibration.
And next time you see this big drop in charge, take screen shots of GSAM from apps and system. We would know then for sure.

Special thanks for your great comment
Fortunately,that horrible battery drainage don't happened from yesterday to now.
This means there is no faulty behavior after last full charge that i have been!
I don't know that reason but i done some actions after fully charged phone yestarday:
1.instilling Gsam battery pro as you have seen!
2.Charging with another charger(2mA galaxy s4 charger)
3.setting screen brightness to 30%
4.setting off "optimized backlight"
5.battery calibration with "battery calibration" app
This new informations from my battery behavior after 19 hours fully charged at last day from now and i hope that horrible drainage wouldn't happen in future else!

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?
