What the title says, or do I need to take it out each time to charge? It's a TPU case.
Wireless charging, you mean? Not usually unless it's super thick.
I charge my N4 in a case but I use a wire so lol
No, I mean wired charging. Just dunno whether it could get too warm in a TPU case? Or can I charge with it on.
If your phone gets abnormally hot for some reason, you may want to be careful. My phone used to get kind of warm, but undervolting fixed that.
Li-po batteries are susceptible to damage above 60°C.
I'm not sure it really matters if you charge inside a case.
I can charge just my N4 just fine in my i-Blason S-case. At first the plug came out with just a little push but now it has normal strength. It just had to "break in".

Hi,
Any of you feel that there is electric charges on ur ear while charging when making a call? when i disconnect the cable it is okay. only on the receiver portion. could it be a faulty battery?
I've not experienced that issue, but then again I've not tried using the phone during charging.
Are you charging from the mains charger, or from a PC?
It is most probably a small amount of electricity "leaking through" down the cable from whatever you are charging it from.
This might sound a bit scary, but is not necessarily a danger or even a fault. PC power supplies in particular have components to stop EMC (radio interference) that can sometimes cause a bit of this "electrical leakage".
If you are using the supplied charger, make sure it is not damp or wet, as this really could be a danger.

Hi,
I am refering to the charger. using PC is okay. i tried with different power point still the same. no it is dry. shld i go to the service center
I just tested the electrical mains leakage current from my own charger.
It's around 15 microamps, probably not enough for most people to feel but maybe on a sensitive part like the ear it's possible. I think that the CE requirement is 250 microamps maximum so it meets statutory requirements.
Obviously I cannot tell whether there is a fault in your charger, but if it was mine and the current was not actually uncomfortable, I wouldn't worry too much about it. I would expect genuine HTC chargers to be 100% safety tested.
i did notice the same from mine while using the wall charger.. on my hand tho not my ear.. more than once.. kind of weird.. but w/e haha
Yes, I have had 4 HTC phones for myself and every of them has done it while on wallcharger. It is kinda annoying when speaking on the phone.
Wizard did it really much and couldnt sometimes talk on the phone same time.
2 Diamonds did it, one i use now has invisible shield so it kinda stays in them because of rubber
HD does that but not much or not at all.
Maybe it is because of aluminium or metal casing on phone like wizard and Diamond, havent yet tested HD much. Got it yesterday :>
Hi,
so it a norm for all HTC device? so it is not faulty?
thankx
When I plug in the usb for my Nexus 4, I start to notice my battery started decrease when using simple apps and the phone starts to get hot. I am running on paranoidandroid rom btw
Sent from my Nexus 4 using xda app-developers app
Don't worry that is a common problem among many android devices.It will eventually cool down.Charging also leads to the phone getting warm or even hot,but it will cool down eventually.
Since USB is not an AC source of power,there will be a very slow charging rate.or it will not charge at all.it happens with me too.
Try not to use your phone while charging. Not only do you affect it's battery health it also gets really hot
Nexus 4 has been reported to get hot easily so try not to use it while charging.
Also, try undervolting to see if that helps your problem. Im sure ParanoidAndroid comes with a custom ROM and root
and you will be able to undervolt
Good luck
Also another thing when I charge, using usb or wireless I make sure to take my case off, I am using the seidio case with is rubber and has a hard plastic wrap around and find that the rubber does not allow the phone to breath when it is charging making it extra hot.

I disagree. I use an X-line hard rubber case and always have the case on when charging. My phone "never" gets hot. It always stays at its usual temperature. And I don't live in a place where the weather is too cold.
Dear L2 G2 owners,
I really love my battery on my LG G2 and since its not removable i want to do the best to preserve its lifespan.
So what i'm doing is, plugging in my phone to the charger when i get home and leave it there even after its been completely charged.
Is that correct or should i leave the battery to complete its cycle then charge it when its almost empty.
What other tips would you suggest.
Cheers!

From what ive read thats exactly how youll reduce your batterys life span
Sent from my LG-D802 using xda app-developers app
The more cycles, the shorter the life span. The thing that will destroy the most is heat. These are good batteries, trickle won't do much, heat is the worst. Don't worry so much about it. Nothing you do is going to have much of a noticeable impact.
Thanks a lot for the info guys!

Btw, these batteries are indeed replaceable. Just not in a normal way, and more difficult than say a MAXX. The back cover does come off. Just a thin plastic back that can be removed going clockwise from SIM tray.

Clockwise while facing the screen or facing the back?
Sent from my LG-D802 using xda app-developers app
Screen to you. Easier to place back starting at bottom and working up to top a side at a time. Just my personal experience.
Any available online stores that provide such replacement batteries?
Also is there a video tutorial on how to open the back cover.
Just in case...

I've done a little research on batteries from such places as Battery University, and learned a few things that might be interesting. I haven't posted enough to post links, but the location after batteryuniversity dot com is "learn/article/charging_lithium_ion_batteries" if anyone wants more information.
It seems that Li-Ion and Li-Polymer batteries are treated essentially the same; the difference is mainly in the packaging. As for charging, they do better if not charged 100%, and never discharged 100%. But one thing they say, which I was told by the salesman when I bought it (but didn't believe him at the time) is that they should not be charged while power is on. The charger is designed to trickle charge the battery, coming on at a certain voltage. But when under power, this cycle happens too often and stresses the battery too much. I suppose it might be OK to charge it while on if you watch it, and remove the cable when it gets to full charge or just under that. I suppose a timer would be ideal.
I just wish I knew how much difference it actually makes, since turning it off means you can't receive calls. I've had devices with Lithium batteries in the past that were left on a charger all night, and the batteries seemed to last for several years, which is probably longer than my phone really needs to last.
I still think its funny that people don't think that there isn't any charging logic in the phone and that it just willfully commits battery suicide if the user doesn't micromanage charging.
Back in the day, early battery tech such as NiCad was extremely sensitive to temperature and the chargers weren't designed with intelligence so they destroyed batteries with 'Fast' charging by overheating. Also, if you never let the battery discharge completely, the battery would start to form cadmium crystals and lower the apparent capacity of the battery. So, slow and deep cycles were the proper way to go. NiMH batteries were far superior and intelligent chargers were introduced but could still suffer the same symptoms of over heating with cheap chargers.
The idea that you can only trickle charge Lithium Ion/Polymer batteries is laughable. The rate of charge is controlled based on the temperature of the battery, if it heats up, the charging circuit clamps the current down, if it is cold it ramps it up. Also, contrary to wisdom applied to NiCad, deep discharges and full charges are harder on Lithium batteries than the earlier tech. In the mid ranges of charge the charger will go all out, when it reaches the top end it slows down to a trickle because the battery is more sensitive to stress at those charge levels. Conversely, if the battery is fully discharged, the charging circuit will start out with a trickle and speed up as the level increases.
On the G2, if there is high resistance across the data pins it stays in slow charge mode, most likely to protect USB ports not meant for charging, if there is low/no resistance it goes into fast charge mode, it thinks it must be connected a dedicated charger. If the charger or the cable gives the wrong setting to the phone the user is left scratching their head.
Luckily the AT&T car charger I bought with my Galaxy SIII works properly with my G2. Sadly the correct cable with my laptop, even with Lenovo's dedicated charging port, it stays in slow charge mode because it senses a data connection.
Edit: Also, the comment about not charging while the phone is on is another hold over from the NiCad days. Lithium technology could care less as all phones have regulated charging circuits now.
Before anyone go crazy, it's most likely my fault. Since the battery is superglued to the phone I had to bend it pretty hard when I replaced the screen. And it was probably damaged
Anyway 6 month later my battery expanded and broke the glass back. There is a very visible bulge on the back (~1/16" thick), on a flat surface the phone wobble. I don't know when or how it happened, at some point I got the phone out of my pocket and it was broke.
I have a strong suspicion it happened while using a 2.4A/12V car charger at -25°C.
My real question (TL;DR) : Is there a risk using a 2.4A/12V car charger ? (my previous one was a 1A and it was barely charging the phone)
Doesnt matter what the current output of the charger is. The device has current limiting technology. It will max out at 1A so if your using a 2A charger your fine.
Also the car puts out 12VDC but it gets stepped down to 5V at the micro usb port. Thats the industry standard.
Now when you bent your battery you started the process of damaging it. Li-Ion batteries have a very thin sheet with paste on it and that is wound up with many layers. By bending it you probably flexed the thin sheet and that soft spot eventually broke and when that happens a chemical process begins to break down the battery. The bulging you are seeing is a buildup of gasses inside the sealed battery its self. When a battery begins to bulge its going bad. This can also happen prematurely if you expose it to over heating repeatedly OR for a long period of time, OR if you allow the battery voltage to drop to low for to long. Li-Ion just doesnt like heat or low voltage.
I concur with IAmSixNine you need to either replace the battery or get a new phone. And be sure to dispose of it properly. I had the same problem years and years ago with an old HTC touch diamond. The battery started bulging and I eventually had to remove the cover and use tape to hold it in. After a couple weeks it burst and it wasn't a pretty site... Pretty dangerous carrying around a battery that could explode in your pocket at any time.

Thanks, good to know that the charger can't damage the battery, I have purchased a new battery lets just hope this one does not explode in the mean time
Ive replaced the battery, the first charge took 8hour to 90% and now it wont charger over 50% is there a way to reset the battery limit ?

let it cycle a few times to correct the battery information.
That means let it die down completely, then charge it completely. Do that a few times and if it still causing issues its possibly a bad battery.
I think I also have a faulty charging port, only the wireless charging is working now, when I plug into any usb there is the lightning icon but it says not charging. I'll switch the daughter board with the one from my other broken nexus 4 to see if it fix the issue.
As much as I like my Nexus 4, I'm not impressed by reliability. In under 2 year, I've had 2 broken screen, 1 broken bake cover, 1 expanded battery and now possibly the charging port. My nexus S and Galaxy nexus with a million drop each are still working as new
One of my friends got one and broke his before the 2 month mark. He was ribbing me about getting a case for it and making it more bulky. I was not the better man...
The thing causes my S8 to heat up, even when I turn off the fast option, more so than fast wired charging. Is it really good for my battery health when the phone is heating up for the entire two or three hours on the charger?
with the official samsung one that has a fan?
The phone will stop charging automatically if it thinks the temperature is not comfortable.
Do not stress over things that are mentioned in the manual, inductive charging will generate more heat than a wire, but the phone is more than capable of managing the process and stopping if things get too hot.
And no, the temperature isn't going to get high enough to damage your battery. (Unless you are using unauthorized wireless chargers / fakes that can cause the actual metal casing to heat up, google this).
I too had this question back when I bought my Wireless Charger for my S7. Interesting to get more feedback from the others. E.g. Does it shorten the battery life quicker considering it heats up the battery more than on cable.
I've wireless charged my s7 since I got it and also wireless charge my s8. I've also added wireless charging to an LG G3 and G4. IMO it does not degrade the battery and fast. The way I look at it, it saves the charging port from 100's maybe 1000's of plugs/unplugs. It's also a point of device failure, so from that perspective, it's better. Again, IMHO.
notice it too.
How about if you introduce the extra variable of putting the thin metal thingies for magnetic car mounts between the phone and the case? Does that change the situation?
Another variable is a case, which can add to heat build-up. Overall, I have seen nothing definitive that suggests that heat won't adversely effect battery life. Notwithstanding the money companies make selling QI chargers.

I believe its to cool the phone
The fan in the authentic Samsung Desktop charger only activates if fast wireless charging is turned on in the phone.
The fan is to cool the phone.
I use the Samsung desktop stand but usually just normal charge it to which apart from typical heat being discharged I've not experienced any other issue.
I do not use a case.
There is opinion that constantly using Fast Charging can reduce the batteries condition over time. Wether you believe this is personal opinion. I've only Fast charged maybe 2-3 times if I've needed a quick boost of juice.
I noticed this too when I put my new S8+ on the wireless charger built into my truck. This was the first time I tried it so I wasn't sure if the phone getting hot was a normal thing or not

Hi, the phone can handle it if it gets too hot during wireless charging.
Always be assured since that the electric current of wireless charging is 1A, which is lower than the current for wired charging 1.6A. That's to say, it creates less heat while charging. So actually the wireless charging helps prolong the longevity of your lithium-ion battery, except for the longer charging time.
Besides, only semiconductors that flow through current could produce heat (such as your phone's cover), the lithium-ion battery doesn't have current go through, so it's safe from the heat.
I only wireless charge in my car. My dash mount is setup for during the warmer months I will have the the AC it vent blowing cool air directly on the back of the phone. If I don't do this, I get the wireless charging pause error caused by the heat sensors.

Fear not, the phone battery doesn't generate heat itself, the smartphone is actually smart enough to protect itself from the heating generated by the wireless charging unless you put it under the extreme heating weather, so the phone should be safe from the heat.
