[Q] Battery Overheating - LG Optimus 2x

Hi all, I get the phone last saturday, and now with all the apps, I feel that the phone was overheating, then I install Battery Monitor Widget and saw that my battery never was never under 35ºC, and only with Wi-Fi on and browser, I get to 38ºC, when charging was about 42ºC so I was worried if my new phone was defective.
So I want to know if this is normal because of the two cores, or I should go to service center.
Thanks

My phone is about 40°C when it is charging, and about 35°C when I use it without charging. So I don't think it's a problem.

[Q] My Galaxy Note is not storing charge??

hello there,
everything was fine just 3hrs before.
I plugged my fone on charging....i dont know why it suddenly started to heat,i havent seen such behaviour in past 2 months.
the fone is on charging,it shows that the fone is charging but the battery % remains the same as it was before..like
i place it on charging with 20% battery remaining,after 2 hrs charging it show the battery is still 20%.
i am using darky rom note with FM kernel....can any body tell me what should i do...whether the problem is in the software or in the hardware....
plz.
Can you take a look at the battery? It should be perfectly flat. Sometimes when batteries go bad they bulge. And how hot does it get. If the battery is hot to the touch my guess would be a bad battery pack.
battery is absolutely fine....using it for allmost 2 months.....battery heats up but the portion of camera & around that is seriously hot,not warm....hot.
You using the mains charger? Mine has packed up after a month, it wasnt charging properly but via usb it was and with my old hd2 charger it is charging fine

I think that is the CPU. The CPU is up there, and (we know) the battery is lower down. I find when I play games etc, the top part gets warm.
It sounds like you may have a rogue process. First off I would recommend a reboot, and then perhaps an uninstall of recently installed apps if that does not fix it.
i have also noticed that the latest version of flash is killing my battery, if you have updated flash try removing the update and then reboot and monitor the situation
Moved To Q&A​
Please Post all questions in the Q&A section​
change ur charger....it might work..

(HELP) Phone consumes more battery than charge?!

Hi guys,
I have an incredible S rooted and running on Android Revolution HD 2.20 . Had that ROM for a month without any problems until today I charge my phone while using my YooBao (11200mAh) external charger , and it told me that my phone consumes more power than the charge, please close all unused applications.
I was like totally lost. I had that charger for almost half a year and it worked perfectly on my device without any problems.
Now the problem that I'm experiencing is that my phone discharges faster than it charges. and that totally sucks. I need some advice,
Could it be my battery faulty or was it the charging port?
My thoughts are your "YooBao" has ruined either your battery or the phone itself.
Hopefully it's just the battery..
That's usually why phone manufacturers ask you to use their products in comparison to other "suppliers"
Update:
I flashed Nik's v4.5 over my ARHD and I tested it by leaving it to charge until 63%.
Feeling glad that at least it's charging up to 63% , I concluded that my port isn't damaged although I wasn't able to charge using my external charger. Pretty pissed.
I went up to my phone and used it while it was charging . To my horror , the 63% dropped to 61% while I was using and STILL CHARGING . WTF?
Now i'm gonna wipe all my apps and do a clean flash and no titanium backups for me .
God.. help
Did you have gps WiFi or large processes running in the background? It could easily do it.

Well , initially I thought it was , until I wiped my phone and didn't restore my apps and I'm sure it wasnt the processes that are causing this **** . Charge my phone overnight and my phone stops charging , woke up to find that my phone is only at 50% charge and the percentage drops super quickly.
Can anyone tell me whether the charging port or the battery is covered under warranty if it's within my warranty period?
Any advice whether I should get an Ankers' battery or should I purchase another original battery that cost me SGD$68?
Couple of things you could have a look at. Check in your battery menu that your phone is on AC charge mode. Also install current widget to see how many mA your phone is drawing while in use and to check the difference when its on charge. The original charger supplies around 900mA to the phone @ around 10%.
Calibrate it?

After a day of test.
Finally I got tired of it and I did a simple test to really test whether my battery is draining too much or not.
I plugged in my phone yesterday night to charge at the AC adapter, surprisingly it was charged to 100% straight with no problems.
I was tired alrd and I used an iPhone 3G as a spare phone. Throughout the day I carried 2 phones out and I noticed something:
At the end of the day, my InCs still had 78%. (WiFi 3G off) .
It means that the draining of my battery is not as bad as it seems. The real problem is that I am unable to charge properly.
When im charging at 61% , I use the phone when it's charging, the percentage can drop to 58% (which is not possible as my GPS is not on) .
So advice people:
Should I?
1) Get a replacement battery,
2) Bring to the service centre (No warranty left and pay)
Do you think:
1) Port problem
2) battery problems.
Let me know

It's for me a usage problem, got the same message too. You're running too much apps at once and never use a taskkiller. You also had GPS WiFi and Mobile Network on and maybe at full brightness. Close apps, I think you need not GPS while charging and if you have a WiFi connection mobile network isnt to be on.

Faulty battery or faulty phone hardware?

So, a couple of weeks ago I went to bed with the Note connected to the AC charger while listening to music when sleeping. I woke up the next morning, only to find an EXTREMELY overheated phone that wouldnt boot or charge. Went to a local electronincs store and it turned out that the battery was dead so I ordered a new one. (Original battery, identical to the previous)
The first day of using the new battery I ran in to some strange behavior, the screen started to flicker as if the phone was running out of battery, the only problem was that there was atleast 30% of battery left. I have been experiencing the same kind of behavior ever since. The phone suddenly drains the battery, precentages increases or decreases when not charging, or the battery is suddenly empty at 15-40%. When I left for school today my phone was 100% charged, when I came home it was probably 50%, I listened to some music, after a while it read 15%, and before the song I was listening was done the phone started to flicker (as usual) and then turned off. I connected it to my PC and charged it for about 30 minutes, and when I turned the phone on the battery read 50%?? So basically I've experienced pretty wierd battery behavior all over.
The screen flickering has occured before when using low quality charger with battery stats at ca 1%, thats quite normal i guess?
I haven't been using low quality chargers on the new battery, nor did I under the incident that killed the previous battery, however, I've been using an original Galaxy SII charger with a 0,7A output, should be totally fine right?
I'm out of ideas what to try, I've tried to delete battery stats after a 100% charge numerous times, no change. Havent seen any battery drains from the battery monitorer. Currently using MIUI Vengeance CM9, havent experience battery drain earlier with this rom.
So what do you think? Battery, phone hardware or software?
try to clean the battery contacts at the back of your phone also clean out some dusts or lints on your usb charging port. Charge it back after to 100% and see if your still getting the same problem.
The same problem still occurs, thanks tip though.

It's unlikely its hardware related, but get a replacement battery from somewhere preferably stock, they're not expensive. It's not hardware, most likely duff battery.

Finally bothered to buy a new battery (again), and so far the battery life seems to be all good!
I guess I was just a bit unlucky by having the orginal battery break, and then receiving a faulty battery after ordering a replacement A series of unfortunate and confusing coincidents

screen flickering - a common problem?

Hey guys!
Recently I read a lot about people who are facing the screen flickering issues on their Note. (YouTubv-Video, thanks to Parth)
For those who don't know about the problem:
When your phone is discharging it'll randomly begins flickering and shut down, then restart with 1 % battery left. The performance of the battery is dropping from around 4000 mV to 2500 mV... A new battery should fix this.
The strange thing I've noticed is that those people bought their Note around 12 months ago.
I bought it in November 2011 and got the issues around 3 weeks ago.
Could this be a common problem? Let me hear your opinion / experiences.
I've had this flickering for the first time about 1 week ago, after I replaced the original battery with a fresh one (from Anker): The flickering began when the new battery had 0% left. But instead of shutting down, the phone was flickering for about 1-2 minutes before the battery ran out of power and the phone was instantly switched off - without a "clean" shutdown. So it seems that the new battery does not "tell" the phone to shutdown before it is empty, and the flickering might be a symptom of a very weak battery. Just a guess...
Yes .. it happens on low battery. have noticed this on 3 notes already

Think you're missing the point of this post...
To op, bought mine same time as you and flickering began 2 weeks ago, plus now needing 2 charges a day on original battery. Have just ordered a replacement. But yes, the timing is uncanny.

geez ..i thought it was just me ... I also notice this just about 2 - 3 weeks ago ... Strange thing is when i recharge it and check the battery starts ...
there will be a drop from 30% --> 0 % and charging starts from 20% upwards ...
I still have the original battery from Samsung ....
Also noticed that the battery is getting hot every time I have the screen on for more than 4 mins ...
I purchased my Note in October 2011
My battery became worse more and more... Recently I got a drop from 98 % to 1 % Already ordered a new one, hope it'll arrive within 7 days

You should see for media scanner issues and wake locks using betterbatterystats
my note is 15 months old. i started having this flickering issue 2 weeks back and got a new samsung oem battery 5 days back. the new battery has manufacturing date of 2012.12.27 on it. the flickering issue was 98% cured after getting a new battery as the only time i got flickering issue with the new battery was when my battery level was 8%.
now the strange thing happened yesterday. i was online on facebook for quite a long time on my note, upto the point when my battery reached 1%. then i decided to give it a rest and turned it off manually via proper power off. my note was turned off for about 2 hrs, then i came home and connected my charger while my note was turned off, but the charging indicator never showed up. i thought maybe it will take few moments for it to show up. i checked my note again after half an hour but it still wasn't showing charging indicator. i tried turning it on but it didn't turn on. i tried putting my old original battery and it worked perfectly as before along with the flickering issue. it was charging as usual so the charger is not the problem. i tried putting the new battery again and still it is neither turning on or showing charging. what am i supposed to do now?
EDIT: i think my new battery has gone into deep discharge. is there any way to revive it?
same issue
Guys i dont think this is a simple battery issue.... I think this may be a media bug on rom Jelly Bean ...
I have the same problem and the batery was full charged with 98% ... I just unplugued for the charger and it just flickered screen and bummm phone off and battery drain... and it allways heats up the phone.... I play a game a lot called rage of bahamut and it started all by playng that game lot of time...
Now the problem is gueting worse... just by watching a simple site it goes down .... this is NOT a battery issue...it must be from the rom or kernel ...
its like something its not controling the battery usage correctly ... it only hapens when its not plugued to the charger....
can some op say something about this issue?? Please

I remember someone Expert on android posted that on Google+.
Just try what I say and you'll thank me..
Buy a new battery brother..
I have experienced all that..
Ive tried many things to solve it..
+Screen flickers afrer reboot right?
+(Maybe) phone shuts off after capturing picture with flash right?
+Battery spins right?
+Playing intensive games makes phone shut down(sometimes) right?
+battery percentage not accurate right?
Im not arguing brother.. :thumbup:
Im just here to help..
All im saying is that I experienced all you said and solved my problem by changing battery..
Im suggesting something that might help you..
If you dont want to buy, then borrow some friend's SGN battery just to try what I am saying..
Goodluck :thumbup:

Overheating After Battery Replacement And Indicator

Let me start by saying I was plagued with the dreaded lollipop battery problem, I had my phone charged to 100% then it used to drain to about 50-65% then die. I handed my phone into a local phone repair shop, they had it for 2 weeks, I went down to see how much longer they were going to take to repair it, they told me that they replaced the battery and the problem was still there, they said they tested the phone as well and charged me for what work they did. I suppose the problem I had there, is how would they test my phone as my phone had a key lock on at star tup?
Anyway I bought a new battery from Amazon, as they never fitted the back cover on properly I was able to take it off with ease, so today 22/08/15 I received the new battery and have installed it, (touching wood) the battery at the moment, is holding charged, since I installed it then used the companion app to repair my phone and unfortunately forgot to wipe my phone, but that's ok.
Now if I do too much like re-install all apps or play a game the phone overheats real bad and drains the battery, I have also found out that the battery is not the problem, its what's under the two metal parts above the battery, both the front and back screens overheat to an extent where I have to turn the screen off to let it all cool down. I have also now noticed since repairing the phone using PCC that the red/orange indicator light stays on.
Ok so after 2 days of usage I can say the battery lasts longer than previously, which means the ones who claimed to have fixed my phone lied.
However when using my phone, my battery does drain faster than it had previously, also it now heats up where it never did before. Its not the battery that heats up though.

Looks like the shop removed some heatsink paste or something... I'd return to that shop if I were you. Make them check it and ask for your money back as well.
They have told me they messed around with the battery, they didn't replace it, however they tried to repair the battery by boosting it. I have got my battery to last from 8.35am to 11.40pm on moderate usage with 45% so that's fine. I am assuming the overheating as part of lollipop due to the fact that is only with excessive use of games.
