[Q] How to fix strange battery behavior?

Since last week I am experiencing a really strange behavior of my battery.
Sometimes my phone (in a random app) just vibrates, the screen goes black and then it reboots. After the reboot I have lost 40-50% battery life. Sometimes the phones isn't even able to complete the reboot because it spontaneously has too little power left. See attached screenshots.
Has anybody had similar problems? Or knows a solution?
About my setup: The problem seems to be not rom or kernel related. It occurs no matter what rom or kernel setting I am using. Currently I am running coool boy's 4.3 GE witch KT's kernel (no OC or UV).
Is it possible that the battery is physically damaged? I have NO IDEA...

Experiencing the same problem. I've flashed back to stock and still experiencing this. Phone randomly turning off, not starting, sudden battery drops. Driving me crazy.

This looks pretty strange 0.o
Consider buying a new recovery

I've seen the same sort of graph on my old i9000. You're not gonna like this, but it got worse over time, and eventually my battery wouldn't last more than 5 mins. I thought buying a new battery would help, but it didn't. When I sent it in to Samsung they said they would have to replace the entire motherboard...
I think it's got something to do with the motherboard not being able to correctly sense the battery voltage/whatever/%. The phone reboots automatically because it thinks the battery is flat (even though it isn't).
If you're under warranty I suggest sending it in soon... Hopefully it's not the same as what I had heh.

Well *#!$
I'll observate it for the next few days and see if it's getting worse...

If your phone is rebooting as opposed to just powering off, then I suspect it is hardware related (motherboard) as already mentioned.
I do hope I'm wrong though.
Maybe try using it for extended periods while plugged into a charger and see what happens. If it doesn't reboot then it may just be the battery.

Right as OP I'm suffering the same exact problem or there abouts. I've flashed back to stock rom, fully charged to 100% drained to 0% back to 100% yet still phone keeps shutting off randomly and the only way it works properly is with the charger plugged in. It's escalated quite badly with now after a few mins of YouTube turning itself off and not rebooting. I've requested a repair by o2 who I'm in contract with and see what will happen. I've heard crap stories about their repairs before taking it to Samsung.

I9500 owner. Had this exact same problem when using older firmware. After updating to the latest one, never had this issue again. Its been two months now, even more.
Try this. Flash the latest available firmware for you phone, not talking about OTA but the downloadable one from any region (whichever is latest for i9505). I guess it may have something to do with the kernel too.
Edit: wait a minute, why is your battery level going up when it isn't even charging in the second screenshot. Middle of the battery timeline. That's weird. I guess you should send the phone back

Thank you guys :good:
In the last few days the problem occurred more often. But now it is just shutting down (no reboot after vibrate) and after plugging it to the charger and restarting it sometimes I haven't lost any battery. Strange!
I fear there is nothing else to do than turning it in (warranty)

Same problem here. It started three days ago and today I'm barely able to use it... I'm still on warraty and I even have insurance, but it's a major inconvenience anyway.

Mines gone in for repair back to my carrier still no movement despite them having it for 2 days now really should have sent it back to Samsung directly. Will keep you guys posted.

Will send it in tomorrow. Lady on the hotline told me apparently the motherboard is defect and I'll get a new S4. Exchange, no repair. I'm fine with that...

That's good to hear, just inconvenience but at least you won't have to pay for it (or have the defect materialize a year later or something)

Hey
I am new here.
but i was looking for information becuase my s4 9505i has the same problem
shuts of almost everytime i open apps too quickly or stream youtube or some other high usage apps etc.
battery drops up to 50 percent then back 40 percent then to 0 percent, the fact it that the phone never seems to know where the battery is.
by the way my phone is not rooted and i have done the factory reset a few times.
samsung... hmmm.. they seem to be real hard to talk to on the phone, i have had to call them 4 times already about the s4 i ahve had since june, and they just play me off like i am some kind of idiot etc. and deny that there is possibly any reason for random shutdowns, phone freezing, and now this battery/motherboard issue.
next bit is kinda stupid, the phone has a few internal scratches on it from when i ahve stupidly had the phone next to keys and all that. im sure they are going to try and void my warranty and say i have mistreated the phone...
had many phones before, maybe close to 50 and never, never, never have had to ring up a company to try and complain etc.....
any ideas.
I am in Australia,
I am thinking of trying the CONSUMER AFFAIRS kind of threats, but i have to word it the right way...

[Q] Vertically jerking screen problem anybody?

Had been very pleased with this device in the the three months that I've had it. Until yesterday that is.
Basically the screen is jerking up and down on its own. When looking at the homescreen, the only way I can think to describe it is it's like 60% of the screen starting from the bottom is moving up and down by about 2mm on its own. I can see it eating pixels as it does so (it eats into home screen shortcuts). It also does this jerking motion when in an application or using a the keyboard.
I haven't dropped the phone, it hasn't got wet. It is completely stock unrooted and was bought SIM free in the UK in December and not tied to any network.
Things I've tried to fix it :
1.Numerous reboots.
2. Uninstalling the couple of apps that I'd installed around the time I noticed the problem.
3. Just done a full battery drain and now giving it a full charge keeping it switched off to see if does anything, (can't say I'm hopeful).
Next step is to back up / get my data off it and do a factory reset. Despite the bloatware, the stock ROM isn't too bad.
I was also thinking of just rooting it and running a cyanogen mod also.
Would be great if anyone has any ideas what I can try or if they've seen this issue before and remedied it. I can't find anything in Google and I wouldn't be surprised if it's just a random bad luck hardware problem -- which is worse than it might be on account of living in Southeast Asia -- but the device was purchased in the UK in December. Anybody know if there is such a thing as international warranty for LG phones ?
Thank you in advance.

I wouldn't root it send it to lg it sound like a serious hardware problem the g2 seems to be plagued with problems

Yeah I won't bother rooting it. A factory reset has made no difference and it's actually worse now and totally unusable, the screen just pogo's / jitters up and down an inch at time constantly.
The phone was bought on 22th of December, I'm pretty annoyed at getting little more than three months out of it. It would be understandable perhaps if I dropped it, or it go wet, none of these happened and the hardware has just failed for no reason.
For sure the LG repair centre where I livein Bangkok won't want to know as it was bought in the UK. And no doubt I'll get slammed for import duty both ways together with eating the postage sending back to the UK. I think I'll feel better taking a lump hammer to it and make a youtube stating what I think of £400 phones that last 2 months and carry no international warranty.

Have you dropped your phone?

Yep it is sad I hope my g2 doesn't go through the same thing i will definitely get a backup device sooner than later but like I said earlier the g2 seems to be plagued with problems which means the nexus 5 prob has the same problems maybe maybe not I'm a little nervous now because in the us most of us buy our phones locked with contract in the UK everybody buys there devices unlocked without contract from what I've heard if your looking for a new device I would wait for the xperia z2 looks very nice

Hello, same problem with me too, mine screen starts to jittering (like there is an earthquake inside my phone) after the latest update for kitkat, the updates says for optimising apps and such.
But recently i realize if i block my mobile data, and only using wifi for the data transfer, my phone stabilize much much better than when i used GSM/3G to do internet activity. When i used 3G my phone jittering like crazy, sometimes bottom half of my screen is gray pixels and bottom up of my screen dancing like crazy almost 70-80 % of the time. But when i block my mobile data and using only wifi, 80-90% of the time is OK, still a bit jitterish, but waaay much better.
There is also member of this forum experienced this and suggest to full cycle charger for couple of times. He say his phone stabilize after do full cycle charger (depleted ur battery until conpletely empty, than charge to 100% while turning off the phone). Im trying it tonight.
I also consult with some cellphone tech support (in shopping mall). They say maybe when i did my update, there are some data corruptions, so my phone did not update properly (corrupted). Because when you factory reset your phone, people said that it retain the latest update of software. So if you already did a corrupted update, it will stay even if you factory wipe the phone.

Seizure ?

It's a hardware issue, it's been discussed on this forum dozens of times. If nothing helps (including updating to the latest available version), send it in for repairs.

Does anybody know how much LG would charge to fix this.

Im taking it in on LG Service Center this morning, the tech guy said its Hardware problem, about some sockets loose or something like that, He fix it and because im still have the warranty, so its free, no idea how much if the warranty is expired. And i still retain the KitKat OS (4.4.2). but my data is wiped out.
So far no jitters... I let you guys know if the jitters comeback.

phone automatic jerking
hello my s9380 phone have too much heating problem…during heat my phone is again and again restarting..also my phone is automatic touches screen and automatic jerking….can anyone help me how to solve my phone problem…my phone is rooted phone….

i have this flickering problem 1 week now i try to find a way to remove the rooted status on download mode so i can send it to warranty... anyone can help? flashed kdz with flash tool but rooted still stays red.. i tried to do factory reset using power+volum down but i cant do it...

Op...sounds like you have a faulty digitizer have you sent it in yet?

After 15 months own this phone, now this problem came to me too so unlucky because this happened after my warranty end...
Such a beautiful monster with so many hardware (screen or lcd) defects

I got same issue recently for many days, typically starts after turning screen on. Finally got it fixed by discharging fully and charging back again. No issue now. And I try not to charge phone too often only when battery is close to zero. Try charge and recharge a few times if it doesn't work. Works for me ?
Passing this on so others can benefit.

Fake Touches

A friend of me tested his Moto-G with my app with the Nexus7II Fake Touch tester and he reported that the Mot-G has fake touch issues also with the measuring pictures like the Nexus7II does. He also told me, that in real life he has absolutely no problem with his Moto-G.
I think, however it is not a real life issue, it is interesting to know, that Moto-G has the same touch technology (and problems with it) as Nexus7II does.
The app: http://goo.gl/qn8qTB
xda-developers thread: http://goo.gl/KBSc43

People say that it might be fake but others say it's legit

I'm not sure if this legitimate either, which is bit confusing.

I just tested my Moto G LTE (model XT1039 peregrine, stock ROM KXB21.14-L1.56) with Nexus 7 II Tester with all 20 patterns and I can report that XT1039's touch screen controller isn't affected by this well documented Nexus 7 2013 TSC bug at all .

On my XT1032 from UK the digitizer stoped working on both the app and web page test i'm kind of confused, is that bad?
edit: okay I tried other patterns this time and it seems that only the first and the third pattern make my digitizer stops...

Interesting.
Just visisted the page on my XT1032 and the phone instantly begins making touches everywhere, pulling on the notifications tab etc...
Maybe this is the reason why the touchscreen behaves kind of weird when the phone is connected to the charger...

Are you sure it happens only when charging? Mine doesn't do that but AFAIK that happens because the charger you're using its providing more voltage than required (happened to me when used a Galaxy Tab charger)

This test messed the touch screen always, I didn't need to have the phone charging to notice the fake touches.
I'm only saying that I have some problems with the touchscreen while charging, not necessarily using this app.
But if the charger is giving more than enough voltage that seems kind of dangerous. I will check on that.

My touch also acts weird every time when charging through PC USB and/or while charging with an unknown Chinese charge that provides 500mAh on 5V... But with original Sony charger it doesn't happens every time...
Maybe it's some kind of hardware and software glitch.

Like many others - digitizer was behaving weird while charging, only this time with an original Apple charger. No-name chinese chargers seem to be fine
This is however not what the OP had in mind. Try the web test - a simple webpage can temporalily disable your digitizer.

I only have the problem while charging when I'm using a chinese (no-brand) charger. It does not happen when using original moto g charger or the LG charger.

What i have noticed so far with the G4

I`ve had the phone for 3 days now and before upgradin from the Iphone 6 ( my first and last iphone) i was really anxious about the many issues listed in the forums especially the touchscreen problem. When i initially got it i started testing everything and I`m glad to say that everything worked fine (sooo relieved) but when i charged it for the first time it charged very slowly, about 3 hours for a full charge, and it got really hot when using lightly the 3rd day a did a factory reset and immediately noticed the the battery charged way faster about 1% per minute ( i dont know how it compares to you other guys) and the phone didnt get nearly as hot. From all this i belive that LG did e very good job hardware wise but i think like many other conapnies fell a little short on the software department and hopefully it will be fixed in the updates to come.

It seems to fix some issues for alot of user so i think its worth a try for anyone whos experiencing any ☺

Mine will start getting hot and eating battery once in a while, but a reboot always fixes that. 1% charge per minute is about what I see on the stock LG charger.

Glad to know its not only me. Have you used a QC with the phone? I ordered a Tronsmart 2.0 QC off ebay hopefully it will work faster without any issues.

I bought the Tronsmart QC 2.0 and its awesome. I go from 48% to close to 100% in the 45min car ride home. I do not notice any heat that is worrying. It does get warm when charging but normal.
My G4 was raging out of the box. Super hot. Brightness was being throttled back between 100, 90, and 80 pretty frequently and it went from 60% to dead in like 15minutes. After I wiped and setup as new, it has been running as one would expect.

Glad to hear that ☺. I actually purchased the wall charger but i guess the performance will be similiar. The one thing i noticed today was the battery life, it seems it is not that great during very light usage but that may be due to the fact that these couple of days the reception has been awful because the carrier im using (Vodafone) is switching to 4G for the first time in my country and ,a little out of topic i know, the download speeds have shocked me, my home connection max download speed is about 400-500kbps and today i witnessed 15-20mbps.

Battery does drain faster in low signal areas. I found that a slow charge at night yeilds longer charges throughout the day. I use fast charge in the car so I can use GPS and still get a charge. But at home and office I use Qi Wireless Charging. I use fast charging at home but only when I am doing heavy useage. I slow charge while I sleep.

How much of a charge do you actually gain in the car with the fast charger while using nav and music with screen on?

Is any of you guys using a micro sd? Im using a Samusng 64Gb class 10 and im experiencing a lot of battery drain even when the phone is on idle and i was thinking if the card has anything to do with it.

I'm using SanDisk class 10 and there's no noticeable difference in my end

It could be the phone is performing media scanning which keeps the phone awake. This should be completed in a day or two.
If you still experience battery drain after couple of days. I'd suggest performing a full format of the micro SD card on a computer. Incase there are bad sectors on the SD card that the phone is stuck on try to read them.

The funny thing is that the the two buying factors for me were the removable back and the micro SD slot, and the only issue I have may or may not be with the micro SD and a slightly loose hinge on the left side of the battery cover but I have experienced that with every phone I had including the g2 and the iPhone 6 without a removable back that had this issue.

Hey,
This is my first LG phone. I'm a bit disappointed, but the camera makes up for everything (mostly).
First of all, the device I'm using right now is the third one within a week. I got it from Vodafone, and the first two had the same issue. When the screen was on, and showing bright things, the front speaker would give out a high pitched whistle sound. You could only hear it initially if you held it to your ear. However in recorded videos it was clear and loud enough to be very very annoying. This third unit is ok it seems, but my advice to everyone is to try the G4 before leaving the shop. It might just be a bad batch that was made for Vodafone, a similar thing happened to me with my HTC One X, that had screen issues, and there too I had to go through several devices.
I did notice lag, Nova Launcher helps, but I'm really looking to root the thing and putting CM or some AOSP rom on it. My S5 seems way snappier with BlissPop on it. The only problem with that is I loose the camera app, the thing I bought it for in the first place.
The battery is ok, but I expect more. I haven't had heat issues. The GPS draines the battery though really bad. If you don't use a charger whilst navigating, you'll go flat within an hour,which is not stellar at all. If you use a normal 2.1A charger, you can keep it on level, or might even add a few %.
The camera is awesome, and the leather back too. Cool that at Vodafone you get the leather and a plastic back in the box.

If you don't use a charger whilst navigating, you'll go flat within an hour,which is not stellar at all. If you use a normal 2.1A charger, you can keep it on level, or might even add a few %.
The camera is awesome, and the leather back too. Cool that at Vodafone you get the leather and a plastic back in the box.

Thankfully I didn't have any hardware issues, I have the Hong Kong version because there's where most of retailers get the phones in my country, I think there's a lot room for improvement software wise and I'm hoping coming updates especially android M, will refine this device even more. I really hoped my I would get the plastic back cover in the box and I'm really jealous of those who did ??

Im starting to notice two more things with the G4, the battery cover (leather) is making a creacking noise when i press it on some areas, and the other one is the with the vibration motor that makes a little bit of noise compared to other phones ive had, has any of you guys experienced this?

Glad to know its not only me. Have you used a QC with the phone? I ordered a Tronsmart 2.0 QC off ebay hopefully it will work faster without any issues.

I have charged it using my wifes samsung QC. Don't notice much difference over the stock LG charger.

I'm not going to resort to a factory data reset because I shouldn't have to
come to think of it maybe I will try a reset

It's up to you, but as you have seen its much recommended if you have any issues.

ghost is touching my screen

i bought mt g4 plus from 3 months (2 giga ram with 16 giga internal storage xt1642) . i unlock its bootloader and rooted it . the problem begin when i charge my phone we anthor charger the phone started to scrolling and touching the screen by itself so i think this prob becous of electricity . but nw this problem happening often when i use my phone with its fast charger and without it .. the only solve for this problem to turn off the screen and turn it on again ..
please help me
note : this problem happened to me with my last phone (nexus 4) in its last days with me .

Are you using tempered glass screen protectors? this is common issue on turbo charged phone when using those. I have 2 moto g4 plus and both act the same.

Cheap chargers and cheap screen protectors will do that.

Maybe it's a software issue, try flashing cyanogenmod.

thank you for your notice

I had the same problem
I also faced a similar issue, i.e. ghost touch when charging.
The screen-guard is certainly not the issue, as the problem occurs only when charging.
Try different charges to confirm that the problem is not charger specific.
I found on the internet that it was a software issue and can be fixed by visiting a service center.
I had tried factory resetting but it was of no use.
Since I had discovered the issue on the first day, I got it replaced from amazon.
You should try updating the software.
Download and flash the stock ROM.
Or try a custom ROM.
If nothing helps, un-root your phone and take it to a service center.

Start with Resurrection Remix.

I too (in US) am having a similar problem with MY XT1644. Have a glass protector, was on for about a month before I started having problems.

I have ghost touch issues on RR along with ElementalX. Mine does it whenever the **** it feels like it on *any* non-ROM.
1644/4gb/64gb

From what I've seen it's a really common issue, the same is happening to my moto G4 (not plus). In lenovo forums this is the official answer forums . lenovo . com /t5/Moto-G4-Moto-G4-Plus-Moto-G4/moto-g4-plus-charging-issue-quot-ghost-touch-quot/m-p/3346441#M845

So, it's a hardware issue.

Yes, I never believed the tempered glass theory.

BTW, I flashed CM14 and N7.1 and still have the ghost touching me wear my bathing suit covers.

Hi Abdelaziz,
The issue you are facing coz u used another charger, the charger probably caused damage to your battery, and as u have mentioned that this issue has also occured when u are not charging..that means you battery is surely affected. and as per my past xperience this will keep getting worse. i will xplain u why this happens.
moto g4 plus's processor throttles at a very high rate which inturn asks for more power from the battery to keep it going. and since your battery is already damaged by ur another charger.. ur battery is unable to keep up with ur device..and that leads to ghost touching. automatic operating..u will also tend to face battery drain.
solution: Get ur battery replaced ASAP. i hope this helps.:fingers-crossed:

It makes sense, btw, most of the ghost touches reported were using the original motorola charger.
