Hi everyone!
I'm the happy possessor of a three-week-old Nexus 4. I'm writing because I think I might have some problems with the charger. If I connect the AC plug to the wall (without connecting it to the phone) and then I unplug it after two seconds and I bring the adapter to my ear, I can distinctly hear a buzzing noise.
As long as the charger is working fine, I said to myself, I'm not taking it as an issue. Well, I think that now something is maybe going wrong: charge times are unacceptable: yesterday when the phone was at 1% of battery left I switched it off and plugged it to the wall. I let it charge for three and a half whole hours before it finally finished charging. Charge times are almost similar when the phone is on, but I don't have to touch it, otherwise it's going to take ages before it fully charges.
Before trying to charge the Nexus 4 with HTC Desire's charger (I haven't done so already as it's written all over the place to always charge phones with the chargers provided), I wanted to know your experience: does your charger buzz as well if you plug it to the wall and you bring it to your ear?
How long does a full charge generally take to you?
That buzzing noise is pretty normal for such AC power supplys. I think most of them do the buzzing thing.
My experience with charge times are similar to yours. From 0% to 100% is about 3 hours with stock charger. 3 hours isn't exactly great, but considering the rather high battery capacity, it isn't bad either. But you are right - If you have a charger with a higher charging current, you can try if it will charge faster.
No matter what amperage charger you use, your phone will only draw a set amount of amps
Thank you all, guys! I can stop worrying now

Simple questions to the long story I wrote below the line(didn't realize it was so long):
I have two batteries that get a red light when trying to charge and they will not charge. I'm using a travel charger that came with the phone (used, not sure if it is the original charger). Input is 110-220V 50-60Hz Output is 5.5V 500mA. Says model T-HT-8125-SH on it.
Based on my findings, the phone should charge with 1.0A so it makes me think this is not an original charger. Old posts stated if the battery was this empty you need an original charger since it is the only thing strong enough.
The second question regards a new battery (just bought - one of the two above) dropping from having about 50% to having 0%. This is described in the story below, but could switching batteries / putting in a dead battery anything like this cause the new battery to lose it's charge all of the sudden? Or could there be damage to the phone other than the battery causing this issue?
Anyone have experience with this? What specs on a charger am I looking for that match the original charger? I may find other mini USB chargers around and if I have one that matches I can try it. I just don't want to damage the phone.
------
I have a wizard I bought used a couple months ago. It worked fine until a water damage issue occurred. I let it dry out for a week and then it was back to working fine. The only thing I noticed afterwards was sometimes the battery would drop from about 75% to 25% really quickly when it did not used to.
Last weekend, it was charging overnight and in the morning it would not turn on at all. I tried taking the battery out and trying to charge it again without success. The orange light usually does not come on. I either get no light, or a red light. Sometimes the red light stays, sometimes it blinks, but usually it is red when I first plug it in for a couple seconds then goes away.
I read recently in the manual that red means it is in LDO charging mode, thus the battery is empty. I thought the battery was dead so I ordered a replacement. It arrived, I stuck it in, it worked.
Now the weird part - I let it charge some on the new battery (it was around 18% when I got it). Then I decided to test the old battery and make sure that was indeed the problem. The phone wouldn't turn on or charge. However, I put the new battery back in and there is no charge. I tried charging it and the light was orange as it should be. However, after a couple more battery switches (I found out about the red light / orange light from the manual at this point so I went to test that with the old), the new battery is acting like the old battery. Both get a red light and will not charge.
Any ideas?
No answers for you but -
My original HTC charger has the following stats:
HTC p/n 70h00051-01
Model ADP-5FH B
Input 100-240v~0.2A 50-60Hz
Output 5V 1A LPS
Thanks for the details. I suppose mine isn't an original charger as it only has half the power yours does (and is a different model). It is probably some generic third-party charger.
For anyone interested, I did manage to get the phone charging by jump starting the battery with a 9 volt battery (saw an old post about it). Just connect the positive terminal of 9V to positive end of battery, and negative end of 9V to negative on battery. I used the metal from the inside of twist ties to connect the two batteries. Hold for about 15 seconds, then see if it will charge. If not, take battery out of phone again and use the 9V for another 15 seconds..See if it will charge afterwards. It only took a couple tries before it had enough power to start charging with my charger. Just don't hold it too long as the 9V is nearly twice what you need.
Anyways - it's charging now and is at 80%. We will see if it works like it should afterwards. If so, then I will have two working batteries for the phone.
Note - this shouldn't be an issue with an original charger that is 1.0A. It seems the third party ones are less (500mA, or my car charger is 650mA). I imagine the original charger is strong enough to get it started even on a completely empty battery. If not, the 9V battery sure is.
Just an update - not sure what is going on. It finished charging and the light turned green. As soon as I unplugged the wall charger, it dropped down to 51%. Ok...so that was weird...maybe it wasn't really charged. So, I let it charge up to 100% again. Light turns green. Unplugged it, dropped immediately to 39%.
Anyone have any idea why it would lose a large amount of charge when I unplug the cable? I'm charging it for the third time now...I'm not sure what is going on.
This is all with one battery (the old one). I haven't done anything with the new battery yet to try and get it to charge, but this might explain how the new battery lost the charge it did have and became empty like the original battery - perhaps it lost it's charge when I unplugged it just as the old one is doing...in which case this seems like a phone problem...hopefully not though.
Hi there! I just bought a Cingular 8525 Unlocked phone and absolutely love it! After having it for two weeks, so far i have upgraded to the 2600mah extended battery and i am currently using PDACorner v20 rom (nonRBSN)
Now to my question, is it bad for the phone i keep plugging it in randomly throughout the day on the charger or USB? I upload files sometimes and i just leave the phone plugged in the computer or I would sometimes charge the phone when it hits 70% and unplug when done and would charge again before going to bed.
Also, is it ok if i leave the phone on the charger even if the light turns green? sometimes charging would be done around times when im knocked out....and usually dont unplug it until i have to leave.
Thanks for your help/replies.

Well, I don't think that's such an easy question to answer. There have been the following reports:
1
Attempting to charge the battery with either PC USB or non approved charger (500mA) if the phone has less than 10% charge can lock up the charging circuit and result in a Red no charge LED showing.
2
Leaving the phone on charge overnight for example can result in the curious situation of having a flat battery and RED LED showing in the morning.
3
In general problems can result if 500mA 5v chargers are used instead of the 1000mA official charger - particularly if they are used when phone charge is low.
Now despite all the above, I regularly charge overnight without problems - and clearly that means the green LED is on for most of the night. I frequently top up the phone with the PC USB and do sometimes use a non standard charger. I have only ever had the RLOD red light of death once and was able to kick start it eventually.
I generally do not let the phone fall below 20% - but even when it does I have had no problems.

Thanks for the reply. I never let the phone fall below 40% so i should be ok on that. But when i bought the extended battery it came with a wall charger but its 500mA.....im guessing its ok for the battery since it was packaged with it.
But i might look into buying a charger from ATT. Leaving it charged till i wake up should be ok then....thanks!
so i was using my phone like normal then all of a sudden it turned off. now evey time i try to turn it on it just turns itself off when it gets to the tmbile screen.... what do i do.
check for bent battery pins, if not that, take out the battery, plug in usb cable on wall charger not pc, and then insert the battery. it should try to charge without trying to start the phone. Let it charge for a few hours.
ok got it to turn on. but when i charge it the battery doesnt take a charge. i have the symbol and light but it isnt going up. as soon as i pull the cable it turns off. i think it might be the battery or a crappy charger. it isnt the stock one. also before this happened the charger would take forever to charge. on my buddies charger it would take about an hour for a full charge.... this is frustrating
ah yea, cheap charger, ive read where they seem to cause dodgy batteries. Does the charge light flash orange and green?
no steady orange
In my experience with HTC products, you HAVE to use either the stock charger or one that puts out 1 amp of current. Most 3rd part chargers put out like 500mA which is enough to charge the battery, just terrible slowly which reduces its overall life. Its just like if you exclusively use a USB port on your PC to charge your phone, it takes forever, and it will decrease battery life.
Hey,
Anyone having the same issue ?
It's very strange because it happens somedays, someothers not at all.
Basically I plug the note to charge, it displays charging, but when I come back an hour later or so... the note is at 1% charge, like it just depleted itself and is just living out of juice sucked out of the charger...
This happens when I plug it in the wall charger most of the time.
When I plug it through USB on my computer (lower charging output) it never does this. And that's also how I managed to recharge my battery to 100% after the first time it did that.
But a week later, now it's the second time and it start to get annoying.
Anyone has any idea ? Is the charger defective or the battery ? Or worse the battery controler ? Anyone knows how to reset battery stats on the galaxy note ? Thanks.
I had the same problem on another type of phone with a usb charger
Would charge sometimes, sometimes not fully charge and then sometimes not at all.
Turned out to be the charger, just get another charger from somewhere
(I find the 10Watt/2.1amp IPad Apple chargers are good quality and provide heaps of juice for quick charging)
Hello
Yotaphone 2 arrived 2-3 days ago and I it doesn't turn on. I can't even charge it. I left it charging for hours but nothing.
I thought charger was not working but it does charge other smartphones I have...Yotaphone text on the charger lights when its charging other phones,
but when I plug it in Yotaphone 2, it doesnt and I when I put ear close to charger I can hear low buzzing noise but cant hear the noise when charging other phones.
Is the battery really dead or what? I asked for a refund of seller.
Package took 25 days to reach my location so I thought battery drained of course but I cannot charge it.
One interesting thing is when I plug it on PC it does recognize the USB Device.
Please, any help!
You can try a different cable, a qi-charger or charge it with the pc.
This is not normal, ask for refund
Ask for a new one or for your money .
After few weeks, I bought tools for disassembling smartphones.
I plugged Yotaphone 2 in the charger, disconnected battery from the phone, heated the battery with fan for 10min, I connected the battery and it immediately turned on and it was flashing android logo.
I left it charging for 10-15 min and the phone works fine.
I've seen some people recording videos about the same issue I had so this helped me to get phone back alive.
Probably the phone stayed for a long time in the warehouse and battery fully drained. Heating the battery with fan (on max temperature) for 5-10 min will make it hot and it will work, make sure it's disconnected from the phone first while the phone is charging. cause it will restart the battery.
