I read that the battery in the EVO 3D shouldnt be charging at any more than 4.2v, according to battery indicator my phone is charging at 4.331v right now. Should I be worried?
From car and hvac experience I would say no. Cuz voltage is always jumping around a little bit around specifications. For instance a car battery is supposed to be at 12 volts but jumps between 11-13 volts. So i would say that your have nothing to be worried about. Just watch the temperature when we start overclocking.
What have people's phones been charging at? Also the battery can get up to 41 C
When idle my phone is @ 3.75 V and while charging its @ 3.98 V. That's using battery indicator from the market with battery at 100 degrees Fahrenheit and @ 49% life.

Using Battery Monitor Widget, mine is charging at 4.34v right now. I don't think my Evo 4g charges that high, I thought it was around 4.1v. I will check when I charge that up later.
On the charger while using it, my phone got to 42C, and above 4.3V. Has me worried
I read something on here a couple days ago that said its normal for new cell phone batteries to become hot during the break in period. Didn't say how long that period was but I would guess a month. And why are you using celsius? That's just making this harder.
Update : 25 minutes charging now @ 4.1 V, 103 degrees F and 60%

I wouldn't be too concerned with the temperature getting to 42C. For it being on the charger, and you also using at the same time...that's not too bad. I've had mine up to 45C when charging and using it. With my Evo 4g, it would get up to 47C sometimes while charging and tethering over 4g at the same time. I never had an issue. The phone has safety features implemented so that it will stop charging if it overheats. I'm not sure what the set point is for that, but when it's activated, you'll get an amber and orange flashing led light. That's letting you know it's too hot.
Haven't looked in to this issue at all on my phone, but come to think about it I do have something weird when charging.. Once the phone fully charges up and hits 100 percent it stops charging. I know this is a safety feature kinda thing but it would hit 100 and then the battery indicator would just show normal while it is still plugged in, and also the battery percentage would drop while still plugged in. Is this normal or no?
A few thoughts here:
1: 43 (Even 45) celsius is NOTHING for electronics. Hell, 50C is 122F. That's about how hot a car will get sitting in the sun on a 95-100 degree day for about an hour. Your cars electronic parts don't get cooked, do they? I read somewhere Lithium Ion batteries can handle up to 60C internally (140 F), and that's safety restraints, which means it's been lowballed. Your phone wont melt from the battery.
2: Yeah, it takes a few charge cycles to set your battery in. It'll run hotter than normal till it does. Think of it like a trampoline. Fresh, brand new, it's hard as hell to bounce on it cause it's so tight. However, after a while, it stretches out, and it's much easier. (Dirty minded people can stop laughing now) Same with car engines, subwoofers, etc. They all have a break-in period. The battery takes about a week to settle in, from what I've noticed. Mine ran hot for the first few days, and it's fine now.
3: 4.325 volts is within 3% of the stated 4.2. It's within the margin of error... But it should also be within engineering tolerances. If the guy who designed the phone/battery didn't allow for a 3% margin of error, he should be given an award for "Worst Engineer of the Year"... It should be 100% fine. Like the poster up there said, 12 volt batteries in cars can range from 11-13 (Id go so far as to say 10-14) and still operate the car 100% effectively. Also, you would NEVER get a full charge into a 4.2 volt battery if you put 4.2 volts into it. You've gotta have a higher voltage on the outside to force a charge into the inside (High school stuff I learned, so I may be a bit rusty)
4: To :Winning:, Yes, it's designed to charge like that. It gets to 100%, and sits there not charging. It will then drain down to 90% or so, and charge back up to 100, over and over. The OG Evo did this, (Albeit not as well) but the battery widgets wouldn't display it. That's why the Evo would drop 4 or 5% in the first 5 minutes of use. You would unplug it, and then the phone would query the battery and figure out that it was really at 95%, and display it correctly. It wasn't really draining 5% of the battery instantly.
5: Yes. Red/yellow flashing light = overheat. You can probably make it do this by sitting it in a parking lot on a 110 degree day in Arizona while charging it and leaving it face down on your dashboard for an hour. You won't fry it in your house unless you have a bad charge cable. A bad charging cable is the ONLY potential source of worry I have about overcharging/overheating/etc. 2$ Chinese chargers don't have any fail-safes installed in em usually. You have a 500$ phone, don't skimp on the thing that connects it to 120 volts of instant electronics death. (Or 12 volts, in the case of car chargers. But that's more like a slow, smoldering, smoky death)... It'd be like not using a condom with the one night chick you met at the bar. You don't plug your you-know-what into ANYTHING unless you know it's gonna be safe
Thanks I've mostly been using the HTC charger. I guess I'll stop worrying
Sent from my EVO 3D
Interesting observation.
Wasn't concerned about the voltage, but was watching the heat level.
With live wallpapers: +10C addition.
My charge temp is 33.9C without.
My charge temp was 42.8C with it.
Guess it'd be kinda hard to cram in a cooling fan for the graphics chip!!! hahaha
I know its bad to overcharge your phone, so when i sleep i leave my phone plugged in and charges in about 2/2.5hrs and the rest of my 5hrs more sleep its overcharging. is there a way to slow down the charge which i can calibrate to about 5hrs and change it back for daytime charging. will be Very useful to me
using:
Ressurection remix pro ics v1.1 + siyahKernel 3.0rc2
Uh overcharge? Correct me if im wrong (someone who may be a little bit more informative), but our phones are made to prevent overcharge. Once it reaches its maximum, it actually starts discharging and then recharges once it drops to a certain point. There should be nothing wrong of leaving the phone plugged in when you sleep.
thats a + to hear =D i dont need to worry about it ty!
although i guess my older phones dont, running GB (galaxy ace, huawei u8220, huawei u8110)
s2 has overcharge protection ,so it should not be a problem
If you're still worried after Kaze's reply you could get yourself a timer plug from pretty much anywhere, cheap too. Set it for 3 hours and away you go.

ok so i noticed ever since i got it my s3 gets very hot with little usage...its only very hot usually at the bottom by the homebutton and when the phone is charging the whole phone gets hot...the battery has been upwards of 120.9 degrees while charging...i'm using the factory charger and phone is stock...nothing really added on, not even many apps...ive even tried a non factory battery with the same results...does those temps sound normal? i'm wondering if it's the phone....
one question....Wi-Fi on during sleep switch to "Never"?
nope...it's set on only when plugged in...should i keep it on never?
Used my s3 today for navigation using Google navigation for a ninety minute drive. Half way through, I noticed the phone was really warm. Thinking that this should be within normal limits, I continued on. It suddenly popped up a warming that temps were too high and charging would be discontinued. This, was a cause of some concern. I then switched off GPS and nav, and switched to my note 2 to continue navigation.
I used my old evo for far longer periods with out it ever getting warm enough to emit a warning.
Is something wrong with my s3? Or is this just how it is.?
Is there anything I can do to not let it overheat while charging and using navigation?
The note 2 also got warm while charging and using navigation.
The charger is a sprint branded canter that I got with my evo.
Both phones are stock. The s3 has the touchstone induction charging mod.
Any ideas chaps?

If it's sunny and warm then you'll need to place the phone in front of an air vent and blow cold air on it. If you aren't charging then the phone will probably be okay if you keep it out of direct sunshine.
In the windscreen of a car on a hot day is the worst place possible to charge a Li-ion battery, particular while the phone cpu is working hard and the display is at high brightness.
Hi,
I've owned the z2 for a year and a week. Unfortunately my warranty is up. The phone worked great this whole time except the past day I dropped it at work. Picked it up, no damage but the phone was off. I had to hold the power button and volume up to get it on. Since then the phone will discharge in about 3-4 hours with zero use where as the day before it would last over a day. After charging it for 2 hours, it maybe goes up 25%. It runs 58-65 degrees in safe mode. And idles around 48-53 degrees. So now after the drop, it runs hot, discharges quick and takes forever to charge. No updates were done so I can rule that out. I was thinking about opening it up and getting a new battery, not sure if that would be the problem. Any ideas?
