BATTERY EMITTING "SMOKE" (Trickle-Charge Kernel most likely responsible?!) **PICTURE*

BATTERY EMITTING "SMOKE" (Trickle-Charge Kernel most likely responsible?!) **PICTURE*
I have been using the Savage kernal with Trickle-Charge since basically the first day it came out. I have been sick all day and have kept my phone on the charger (because I was sleeping and not leaving the house). I was working (I do alot of work from home) and suddenly I thought I saw a small amount of smoke above my desk. About a minute later a thin veil of very light smoke was comming out of my Evo. I really FREAKED OUT and without thinking picked it up as fast as I could and put it in my bathroom and closed the door (i've heard about exploding batteries and I wasnt going to take a chance). It was VERY hot to the touch and I had to hold it by it's sides. About two hours later I went into the bathroom and the phone was off, and I try to turn it on nothing happens. However, I think the phone is fine, the battery is probably just ruined. Could it have been because of my trickle-charge kernel? It was a stock OEM battery.....
also, I WAS NOT OVERCLOCKING
I have read the thread Trickle-Charge thread in the Q&A section and it seems like it all may be tied together
EDIT: I threw the battery out in the snow a few hours later, popped in another stock one and the evo works! HOWEVER there are weird stains/marks on the inside of the battery cover (maybe from heat or something?). I quickly ran a NAND of some other non-sbc kernel rom and so far so good
PICTURES COMMING TOMORROW (when I am more awake lol)
Also check out this thread, it's kind of the hub to all trickle-charge damage LOL:http://forum.xda-developers.com/showthread.php?t=890448

Notice the weird dark stain around the middle of the battery cover. The battery is in my garage and I will take pictures of it later, but it looks normal (as far as I can tell).

You aren't the only one.

Yup, it was bound to happen. There is a reason why these phones are designed to charge the way they do.

o ****!
to say the least

You mean HTC had a reason for the way the EVO battery charged stock. Funny how that works. Never liked the idea of the trickle charge kernel's.

Lucky it did not burn your house down or explode as you were taking it into the bathroom.
Then again I guess a loss like that is worth a 10% increase in battery.

You may have done this already, but make sure you remove the battery and properly dispose of it. You don't want it leaking caustic chemicals into your phone.

I think SBC (Savage + MIUI) killed my battery too. Left it charging after work and it wont turn on with that battery. Swap it with a cheapo one and it turns on.

Wow I just got my 3500mAh and flashed a sbc kernel...After hearing this I'm about to find a non sbc kernel that my phone likes...smh

Take it outside, it can still catch on fire. Look up a youtube video of one burning and you will see why you don't want it in your house

What sucks about not using a sbc kernel is that your phone will never fully charge the 3500mAh. You will have to buy an external charger. You may see a little improvement over the stock battery when charging it in your phone.

Did you cry while running to the bathroom and then use the other bathroom to change your tampon too? ****in' pull the battery out of it, man up and save your phone.

Why would you pull a battery that is releasing oxygen/on fire? I would have thrown the phone outside or in the toilet. 500$ is not worth your life or a body part. Youtube li-on explosions.

Because the faster you take away the charge and less time you leave it collect heat in a closed phone the faster it will NOT explode. It's alright, i forgot that this place was full of neckbeards who probably call 911 for stubbed toes and when they see steam coming out of a neighbor's dryer vent

I agree. Whats the point of having the phone at all if your miracle to saving battery is essentially removing all of the features that make it a "smart phone". Its like saying "I get unlimited battery by simply plugging it into the wall and keeping it on wi-fi. Just dont go anywhere or doing anything. Its great! I did already beat Dungeon Defenders three times.... I wonder what the outside world looks like? Oh wait there is an App for that!"

The point of a smartphone is to have the "option" to have all the stuff on all the time. A smartphone gives you a choice. That's what makes it smart.

There is the issue right there. Many of us rely on our apps to automatically use said data services - such as email, weather, twitter, etc. pretty much all the things that people tend to buy a smart phone for - and turning it off defeats the purpose of having such a device.

Nexus 4 Battery Life

Hey there..
I'm thinking of getting this phone, but in every review, they say the battery life is pretty crappy... can somone please share their experiences or stats on this please?
Thanks!

Nobody has one yet....
FFS

even if it is horrible. These press units aren't being used "normally" or lightly. They are constantly being hammered to get every last thing about it to talk about.
We have kernels and roms to go on. My Galaxy Nexus last 35 hours on a single charge on a stock battery. While some people struggle to get even 10 hours on it.

Wait for the gsm arena battery test results and then compare the hours to other phones to see how it performes

Exactly. my guess is also that it's because of the phone not being in the final software. Otherwise how could the same battery prove that worse compared to ICS lg Optimus? Jelly bean had a much better battery life in general too...
And IMO that is also the reason for the poor performance

Let's hope everything will be alright after the software update

LG Nexus 4 Battery Easily Replaced

The trend toward devices with internal batteries, ones that can’t be replaced, has come at the dismay of many power users who often need to switch to a fresh battery in the middle of the day. The Nexus 4 has a “non-removable” battery like most people expected, but it looks like it might be a lot easier to access than many might assume. You’re probably not going to make a battery swap in the middle of the day, but if you run into an issue with the battery, at least you know it won’t be impossible to replace.
Defective batteries and burn-out are a real concern with modern mobile device batteries, and while it may be fairly rare for something to go wrong, anyone with a smartphone who’s not willing to disassemble the entire device can tell you how frustrating it is to lose a phone to a bad battery. On November 2, a follower of Brian Klug, Senior Editor for Anandtech.com, sent him a tweet about battery replacement for the Nexus 4 on Twitter. Mr. Klug responded:
@aatifsumar there are two torx screws, then some plastic clips, it’s easy
Aatif pushed for a little more information and Mr. Klug responded with a great photo of the battery situation:
@aatifsumar two screws, boomhttp://twitpic.com/b9pbsj
The 2100mAh battery should be fairly capable of handling a day of moderate use, but for the fear of battery failure this is great news. Mr. Krug came through with another photo a little later giving a bigger picture of the situation.

Doesn't really solve anything anyone is talking about here. Being able to replace defective batteries is a separate issue from the phone's poor battery life.

2. If not, read more!

i think they plugged in charger at the red square
surely, it is impossible to reach 16 hour

Yes that's true. The nexus 4 consumes lot of battery life when the wifi is used.

I take all these battery complaints with a grain of salt. First, software was not final. I find it hard to believe it is going to be THAT much different than Optimus G.
Something else -- I had a friend who got a US GS III and had terrible battery life despite doing everything. Exchanged for a new one and battery life was double the first one. Do you think any of these "get it out first" reviewers considered this as a possibility? Heck, most of them didn't even mention that Google told them the OS code was not final.
It is worth noting that LG has had battery issues in the past. Was one of the reasons I didn't get an LG last year.

I'm finding the battery life to be pretty good. Over 36 hours and still going for light use. By light use, I mean I played a couple of videos, made a couple of calls, general internet surfing, lots of drop box syncing and more. Mostly all over Wifi. Also some wifi tethering for an hour or so. I also find that the battery charges quicker than normal too. Hope this helps

This I had my phone use 35% in 6 hours. That with usage.

what is the point of wireless charging?

Just don't see the point. I mean when they said "Wireless charging" the first thought that came to mind was a means of the phone extracting energy from the no where and recharging the phone somehow... but no its nothing that cool. Just a dock you can lay the phone on...whoopity doo.
I don't see how this could be any advantage other than reducing wear and tear on your usb port, and I can see it being a disadvantage if I want to play with my phone while I'm winding down for bed.

I use the phone in the car, and it's nice to not have the phone tethered to a cable there. Also I have at least 3 devices to plug in at night on my nightstand, you understand how messy that gets when you're fiddling with plugging and unplugging cables.

You and me both

You should be complaining about features the phone doesn't have, not the other way around.

this is a small use, but one I will appreciate... I hate having to use my phone as a flashlight to find my cable and try to plug it in by feel at night... the idea of a phone crash pad that charges is appealing to me. I realize it is less efficient, slower, still requires the pad to be plugged into the wall etc... but I'm lazy, and I'll appreciate it.
Also, it makes for more configurable docks, no longer limited by needing to plug in. Also easier to make a case with battery built in... but lower efficiency so defeats the purpose.
Potentially in the future we can make use of tables and bars at restaurants that detect and charge devices (starbucks is supposedly doing this soon).
Id like to have a computer with it built in so if I set my phone next to my laptop (as I frequently do) it will charge.
As for NFC, the uses are greater, like having an nfc tag on your router so people can easily get the password, quickly syncing bluetooth, as an adjunct to other sensors to initiate tasker profiles (ie. NFC tag on seatbelt that goes across pocket with phone in it initiates bluetooth sync to car)...
I dunno I'm making this stuff up as I go and I'm not the most creative guy... the thing about these sensors and abilities is that they add potential. Orientation, magnetometer, accelerometer, barometer, light/proximity sensor, cameras (front and back facing), some phones have pressure sensitive grips, nfc, gps etc etc... In the hands of the right developer you can create really interesting functionality.

The main thing is that a lot of these features Google is throwing out isn't entirely useful for the world today. With wireless charging, as benhc911 said, we could have tables at places or just a mat where people could put their phones and have them charge. I wouldn't be surprised if Google HQ had a table where people would put their Nexus' to let it charge, it would definitely be a lot more convenient than several ports and wires going around the place.
With NFC, it has most utilities in applications such as Google Wallet, but likewise, it hasn't been adopted entirely yet, and perhaps might after the iPhone brings it to their device. Same with beaming, there aren't that many devices that have NFC, and though they are big ones, the current applications are not that useful. Bluetooth just seems to work better in my opinion. With a much shorter range and ability to transfer at an extremely slow rate, combined with some security bugs apparently, I feel NFC is more of a step backwards than forwards. Then again, NFC tags and Google Wallet do seem nice.

Wireless charging will reduce the wear and tear on the USB port. It also makes for a cleaner nightstand/desk/work station for some of us. Not to mention that it is pretty cool.
NFC is also pretty cool. If you can find stores that support it, paying with Google Wallet is nice. Is it necessary? No, but it's cool. You also have the ability to use NFC tags. Look those up. Of course, you also have the Beam capability or whatever it is called.

Once you try it you'll never want to go back. I wish I had wireless charging for all my devices. I have 3 or 4 things to plug in every night. Being able to just plop the phone on the night stand is a wonderful luxury.

Damn... the whole wireless charging on public tables concept actually sounds useful! If that became the norm battery life issues would be nearly solved, since all I have to do is walk into my neighborhood Starbucks and charge.

Especially if the table detects your phone via nfc, starts charging, connects you to their Wi-Fi and asks if you want to open their menu our order your usual... some day maybe... a man can dream can't he?

That's really what I was looking for. I ain't complaining about it, I mean it's not driving up the price by any means just didn't understand the appeal. Sounds like it could be useful someday

I'm not sure of this, but I read somewhere that wireless charging is way slower than normal cable charging, so even the utility of charging your device in public places is a bit compromised

I keep thinking your going to shorten the life of your built in battery too if you use this feature constantly especially if it's rather slow charging. Li-polymer batteries can be fully recharged around 500 times and every time you plug it in and unplug it that's - 1 from your charge count.
What I really wish they did was cram a 3200mah battery behind the glass. It can be done and still keep a thin profile, just check out the razr maxx

It should be cear that most of those charging limits refer to the number of charges before the battery degrades noticeably (usually to 80% of its original capacity). It doesn't mean the device keels over at that point.
But yeah, full charge/discharge cycles are definitely the best for a battery. That doesn't mean be stupid and let it die while you're out hiking so your buddy can break his ankle and you can't call for help; it just means if convenient, do full power cycles.

What's wrong with my note 4 ?

Hi everyone,
I have a Note 4 (SM-N910F) running android 5.1.1 (build LMY47X.N910FXXU1COH4) for about 1 year and a half now and i'm so surprised of how the performance have decreased, plus i have some weird things happening every now and then such as :
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Having no internet connection, but i'm on wi-fi. This doesn't come from the network i'm using because it happens even when i'm connected to a different one.
My battery life is really ****ty... Plus when i'm around 30%, my phone shuts down and when i turn it back on again, i'm like at 1%.
I'm not root.
I really don't know what to do. Is there any information i can give you that will give you tips on things i'm maybe doing wrong causing my phone to have weird behavior ?
The thing i want to know is if flashing a new rom was a good idea, and maybe if you have advices to give me on roms.. I'd like to be as up to date as possible, and a light rom. Doesn't care about touchwiz feature. I just want my phone to be reactive, fast, and working normally.
Thanks for your answers.

Change your battery. Some posters claim to have lag when their battery are nearly dying as well.

Do you update regularly (Apps & OTA update)?
Try to turn off WiFi & then turn it on again.
As for battery....it's degraded to only 70% of its full capacity.
Usually when it reaches around 40% your phone will stutter + lagging heavily, so make sure to charge at around 50% if you are still considering to use that "broken" battery.
My Advice is to buy a new OEM battery or any good 3rd party battery.

It is a little similar with my 2014 Note 10.1. It also shuts down on its own at right arount 33%. But only sometimes. And yes, it also stutters. I can not vouch for other branded devices. But, I have heard similar stories from friends on their Samsung devices. Definitely get a new battery. Like another post staited. OEM is a great choice. Or, at least a very reputable 3rd party. I purchased a battery for my Note 10. And even though it was new, it was not the same. I found that the circuitry in the cheap aftermarket battery was sub par. The seller sent me a free replacement battery. And it also had issues. So, make sure you get a reputable battery.

Batteries aren't linear though. Its voltage drops off in a curve. (e.g. 4.2v = 100%, 4.1v = 90% and 3.7v = 20%)

Same problem on my 10 months old Note 4 N910C. And it was started about 2-3 months ago, so the battery lasted about 6 months!? Also, there's a burned-in damage on my screen (notification bar)! Yes, warranty is still valid, but anyway... NEVER AGAIN Samsung phone!

You also need to look at your signal - it is awful and you have some wicked wake lock issues that need to be addressed.

Hm... You right about signal. I never looked at this, because whenever I use the phone (at home) and I'm always on 4G internet (unlimited plan), signal meter is on 1-2 bars.I don't know why is signal so bad, when phone is off. Power saving is always ON. About wake locks... I believe that they are from my smart watch (bluetooth),but Bluetooth version on Note4 should be low-power (connection is lost when I'm 4 meters away (in my department)), so... This days I can't reach 2h of SOT (4h-5h when it was new).

Interesting. I'm curious about the power saving if that actually reduces your signal by keeping it in a lower power state. I have never used power saving mode and my rom doesn't recommend it. I wonder if running in normal mode would effect it.
Might look at what apps are using the bulk of your battery as well to see if something rogue is running.

Before Note my phone was Sony Xperia Z and power saving on that phone did a great job.That's why I still use this feature. I also put many apps into the "optimizing mode"... There's no any special app which uses battery. There was Facebook, but I uninstall it.Battery monitoring apps are useless for me because phone is not rooted (still under warranty). Maybe I should try hard reset.

I know it's old thread, but anyway... Last week I finally take my phone to the service, because it's still under warranty. They changed the screen because it was burned-in, they changed the battery (sudden power-offs) and strangely - they changed some faulty system connector. Phone worked and charge befor the repair. I always use only original charger, so how can be some system connector burned??? They changed it for free under warranty, so I assume that it must be some factory fault. I know few people with the same "sudden power-off" problem on different Samsung phones, so...
