Hi. Please excuse my English. My HTC 10 remains warm as long as it is plugged in, that is, even several hours after the green led started to flash. All my previous phones aborted the charging process and cooled down after the battery was fully charged (Of course, I use the bundled charger). This is very concerning. Does it mean that the phone overcharges? I always turn my devices off before I plug them in and begin to charge them. Thanks.
I think this pretty normal. What means warm to you? 40degrees celsius on charger is normal for this device. It does not matter if you charge while turned off as the quickcharge technology works either way and will not quick charge after reaching 80% load. I recently read an article of someone who charged his 10 with an google pixel c charger ( usb c 5v, no quick charge). His 10 loaded normally until 100% but charging procedure did not stop and phone shut down after reaching 50degrees battery temp... maybe your charger is faulty!? How fast does it charge?
I can tell you that my phone tends to get warmer (keep in mind I said warmer, not hotter) when it is plugged in and I am doing stuff (Youtube, browsing, etc...). It will most likely keep warm unless you are not doing anything. I try to not charge my phone overnight since I usually get up to go to the bathroom or get water in the middle of the night, and since I only got like 2-3 hours of sleep left that's when I plug my phone in. You say you turn your phone off when your phone is charging so I'm unsure why it would get hot.
Clarifications
Thank you very much, xperia x root.
By "warm" I mean that the actual phone (not the charger) is above room temperature, unlike any of my previous phones, indicative of redundant electrical activity, which, to my fear, might be overcharging. This is why I wrote that I turn my device off before I charge it: it means that the phone does not consume power, and thus that there is no charging-discharging routine going on. I am yet to measure my phone's charging time.
There's really no need to turn off your phone every time you charge it. My phone gets slightly warmer when quick charging compared to using the regular charger from my previous M9. If you Google "overcharging cell phone", you'll find so many articles about how it's a myth because the phones are smart enough to know when to stop taking a charge when it's completely full.

Yeah i meant the phone too. This phone is always above room temp . Nothing to worry about. While Im typing here(chrome desktop modus) my device battety temp is 40degrees. While using phone during charging it even gets 46 degrees warm, before throttling very hard. I'll watch temp today when charging after reaching 100% and post my temp.

Thanks, xperia x root. When the phone is off, it should, eventually, reach room temperature. That's why I fear that my phone's warmth indicate overcharging. I completely understand that it is unnecessary to turn the phone off while charging, but if it is on, you just cannot know if the heat is due to overcharging, or some operation of the processor. This is why it would be most helpful if you would, only once, for the sake of our experiment, charge your HTC 10 today while it is turned off. And I think you shouldn't watch the temperature, but simply touch it with your hand and feel if it is in room temperature or not. And it would be very helpful if you examine the phone's warmth sometime after the green light is on -- one hour, for example -- to be sure that the phone had enough time to cool down. Thank you very much!

My HTC 10's charging time looks normal, on par with what you see and hear from other consumers and reviewers : it took 1:33 hr to reach 100% from 10%.

Hi every one,
As far i know, there is a BUG on every official ROM for European GSM Touch Pro2.
When your battery get full charged and keeping it plugged to the wallcharger, then your Pro2 start taking the power from your battery and NOT from the charger.
This can be checked by yourself and you will see that even with it connected, the battery in running down charge, till you unplug it and plug it again after some minutes/seconds.
Yeah, I have noticed it as well. Anyone have a solution?
Not a bug. LiPoly's do not like being trickle charged, therefore the charger turns off.
I have not verified it on the TP2 but I suspect that if you let it sit long enough the battery level would drop to some level and the charger would charge it back to 100%.
This is a rather good new if it can manage battery loads cycles...

No it is NOT doing that, so to me it is a BUG.
just thought i would add this
for some reason on saturday i charged my phone via usb/pc and it lasted less than 24 hrs
so on sunday i drained it and charged it vis the plug
its still going noe
72 hrs 23 mins in stanby 30 mins talk and 4 hrs 7 mins use since 17.43 on 18/10/09
is never been this good so i thought it may be the new rom

Lithium-ion
(Li-ion)
Do charge the battery often. The battery lasts longer with partial rather than full discharges.
Do not use if pack gets hot during charge. Check also charger.
Charge methods: Constant voltage to 4.20V/cell (typical). No trickle-charge when full. Li-ion may remain in the charger (no memory). Battery must remain cool. No fast-charge possible.
Rapid charge = 3h
also i have read some where on xda that once it reaches 100% it'll stop charging

You know of any other modern phone that runs off the mains without the battery? None of my last three phones would without the battery.

My Kaiser will. It turns off when you pull the battery, but you can turn it right back on.
Every one is talking about battery and it's components but no one speaks about that with charger pluged in, it should supply power and by pass the battery once it is fully charged like others models do.
sounds like you all need to do warranty exchanges for that lol

Have in mind that once the battery is fully charged, it never go to charge again till you unplug the cable of your wall/car charger... so what will hapen then???
hello anyone know about the issue with the battery ok when i charge my euro tp2 all night and when i go to start>settings>all settings>system>power i then click on the infomation tab and under last full charge i get "not applicable" and get 0 hours and 0minute for the rest
im running the offical htc 6.5 rom
To me this sounds CRAZY. So people are saying that when the device is fully charged it starts to use its battery, thats just crazy... So basically charging it overnight leaves you with "almost" full battery in the morning...
I havent noticed anything out of the ordinary, and every morning when I come and take my device from the charger the charging light is green (opposed to the orange when started charging) and the battery shows to be 100% full.
I will check this again in the morning as I havent really paid 10000% attention to it, but I think I would have noticed the weird behaviour…
noticed this since day 1. my dash didnt do this. i did notice that a soft reset will resume the charge.
This is normal behavior for battery powered devices.
When it's plugged in, the charge circuit charges the battery.
The device itself always runs off the battery when it's available, this is why some devices won't power on without the battery installed, and many devices won't power on with a failed battery installed.
Laptops do the same thing, though they can switch to AC only without losing their state.
It's a holdover I think from when electronics couldn't switch between power sources fast enough to not lose anything (I remember the original game boy would reset no matter what if you tried to switch between batt and AC). It's possible that cell phones can't make this transition since there isn't really extra space to stuff in the bits that allow this (some large-ish caps).
I've also heard that this reduces wear on the electronics, because the voltage is more reliable, but I've never seen that documented.

I don't think this is true for (modern) laptops. All the macbooks and thinkpads that I've owned had a feature that if you plug it in while the battery is above X% (usually around 96) it will not charge. It even gives a message saying "Not Charging" in the battery status. The battery percentage then stays constant no matter how long I use the laptop, so it is not DIScharging either. Therefore it must be running from AC. If it can do that, I doubt they would have it run off the battery as soon as it is charged to 100% on a full charge cycle. I think any time AC is plugged in, a modern laptop will run from AC rather than battery, regardless of whether it is currently charging the battery. However, that's just my theory from personal observations.
I'm still relatively new to the whole android platform. Evo being my first. Why does the evo not sleep when charging? I have the issue of rapid battery drain when I unplug the phone from 100-90 in a matter of minutes. This bugs me to no end. The only way I am able to get around that is to watch for the phone to ding 100 and immediately unplug it and turn it off.
I believe that, and (correct me if im wrong), if your phone is awake, it is being used to its full capacity all of the time. CPU is running and doing whatever it does that drains the battery like it does when its unplugged and being used by the user.
Since the phone doesn't trickle charge it stops charging at 100% until it gets down to ~90% (all the while still reporting that it is at 100%). It stands to reason that if the phone doesnt sleep while its on the charger, its using this cpu power and this is the culprit of the rapid battery drain, and to that end, the culprit of a lot of people's battery woes.
food for thought i guess. that's my take on it.
There are numerous discussions about the charging thing. Search, or at least Google. The most intriguing answer I ever saw to this was that the charging system was set up to protect the Li-Ion battery from degradation by not cramming it full of charge all the time. (The OP on that was a bit more technical, but you get the idea.)
If it bugs you that much, you could root your phone, flash a ROM that is undervolted and compatible with SetCPU, install that, and then set a profile up so your phone is underclocked when it's charging / charged.
I searched xda prior to posting specifically about sleeping while plugged in. My query isn't neccisarily about charging bit rather the sleep function and awake state of the phone while its pretending to charge.
I'm curious as to whether this is hardware related or not. For example when the phone reaches 100% and stops charge could the phone then actually begin to sleep. Unless its physically impossible for the phone to sleep while there is a usb chord plugged into it.
A little test I did with this over the past two days. At night I charged to full and took the phone off the charge and went to bed. I woke up and only lost about 4% all night and was able to use the phone on the way to work never going below 90%
The next night I left the phone on charge all night. Wake up take it off the charger and within 10 minutes I'm down to 92%
Keep in mind I'm not blaming charging on this. The first night lasted longer off of the charger than the night on the charger simply because the phone was allowed to sleep through the night.
I could be wrong
you can set the options it will say 'screen stay on while plugged up' or something to the like
or when you plug it in, just push your lock button (the top power key)
also you can get a brightness widget and put it on your home screen. that way you can still have your screen on while charging but it will be dimmed or whatever setting you set it too.
hope this helps!
Your screen being on vs off while charging does not factor into the asleep vs awake time of the phone.
for an example of this, a freshly rebooted phone on the charger, with the screen off for 5 minutes, will have an "up" time of 5 minutes and an "awake" time of 5 minutes.
this is true while the phone is plugged in and the screen is on or off.
simply put, your awake time on the phone is always going up as long as the phone is plugged in, double this with the fact that the phone stops charging at 100% and you have constant drain even when plugged in.
the phone shuts off at 100% to protect the battery. If you want your phone asleep then turn it off at night. that is the only way to put the phone to sleep try searching app market. Other then that the only other way is to push the power/lock button at the top
Mobile internet fail. Sorry double post
My Dinc is having an issue. It had been charging, although though i think it had stopped for some reason. I was looking at it, making sure I wasn't running a ton of radios/apps and whatnot,when suddenly it just shut down, and now it won't come back on. The amber light is slowly blinking steadily. This has never happened before, and I'm not entirely certain what to do...it won't even let me HBOOT. Someone help plz?!
What kind of charger are you using? The blinking amber light usually just means its charging up from being dead, so you can't turn it on yet. I've had my Incredible use more power than the charger and actually discharge when plugged in. Rare, but can happen. It's not giving you 5 vibrations or anything right?
pull the battery out for a few seconds and it should turn back on
Sounds like your charger is too weak. After doing a modification job on a charger of mine I discovered that the charger was so weak that the phone was actually backfeeding and discharging at a extremely high rate. I recommend a charger of at least 750 mah's. The ones that ship with the phone are 1 amp and work like a charm. Older chargers for lots of other devices are as low as 300 mah's (which will work if the phone is off, but if you're actually doing anything, it's too weak).

thanks for the info..
Thanks guys, it seems to be fine now. I'm not sure the issue, but when looking at the battery stat graph, it should what can only be described as a "plateau-like" droppoff. It wasn't gradual. I flashed the OTA 2.3.4 via Stang's post, said "ehh I forgot I didn't like Sense" and reverted to my nand b/u of CM7.1 RC1. I decided to retain the radio. Now a few hours later, it did that. The only thing I can think of was perhaps the battery stats? Perhaps I didn't have as much charge as I thought? I have since wiped everything, stats included. Seems fine, will update you if anything else happens. And I am on the factory charger(s).
Yeah, sounds possible that your battery stats were all garfed up and your phone thought it was at a much higher level than it actually was. Mine did that after my accidental backfeeding charger. It'd say it was at 87% and then about 20 minutes after being on the charger die, though the % never dropped. After charging it enough to boot it'd say 0%. So yeah, I think it's pretty easy to confuse the battery stats.
Just wondered how most people are charging there One X? Personally I always turn it off and allow it to charge until the light goes green. I've never charged it when it's still been turned on.
I've never switched off any of my android phone's whilst charging. What happens if you get a call? I also try to alternate between charging on my pc and the wall charger.

Yeah fair statement, I had thought about that. I wasn't sure if it was bad to say plug the phone in at 11pm until 7am (8 hours) charging whilst it being turned on? I assumed if it was going to be plugged in say for that long that you should turn it off.
I just plug it in - went to bed on 80% last night but fair enough I'd hardly used the phone all day (standby battery life is incredible)

So you stuck it on charge just to boost that extra 20% yeah? How come you didn't just leave it until it was low?
Should of asked if people would partially charge it or if they always ensure its fully charged.. Can't amend the poll now though.
I was thinking about trying that - might do that tonight and see how it lasts...

Where did you hear that? Mines dropped to 14% before and I then turned it off and charged it and the battery still seems fine. Wasn't aware you could damage the battery if it got too low...
I killed my battery first 2 charges - never have in the past but thought I would this time
I have always charged with the phone on, all my phones since way back having an analogue Nokia mobile and never had any battery issues. Only time I have ever switched my phones off is if I was getting on a plane or the battery got really low and didn't want it to go completely flat.
Just plug it in whenever. Modern li-poly batteries doesn't have memory and charge cycle life is based on full charges.
Part charges actually increase life due to low % cycling

Agreed.
One thing to note is that you should never let it completely drain the battery, the phone will switch itself off once the battery reaches critical level then it needs a charge. I'd recommend charging it when it reaches 5-15%.
Also I'd never leave it charging over night it interrupts the cycle, if I have to charge it over night I set an alarm to go of after a few hours and unplug it.
i have 3 or 4 charges from different makes-and only htc charges the quickest. the worst is usb cable and car charger. but due to usage i need to charge twice a day

You are 100% right most modern phone battery’s don’t have memory any more so no need to worry about it, and no need to do full discharge and recharge cycles to maintain battery health, and if they do they normally tell you in warning labels or in instruction manuals, for example I recently bought a new shaver and it tells you to do a full discharge and then leave it on charge for at least 12 hours every 3 months to maintain battery life.

batteries have safety features built in so don't worry. What for you looks like 0-1% left - what android is showing you, might be actually 10-20% as seen internally by the battery.
Also, I have completely discharged my phone once, I simply left it at 1% and waited until it shut off. Then I charged to 100%. From then on, I charge whenever I want, phone is always ON.

Hi. I am using the bundled moto turbo charger with my phone and have noticed that the phone sides and back get hot mid-charge when charging and cools down when the battery is about 80% full. Is this a problem with my phone/charger or does it happen with you guys also.
Its cause of the Turbo charger
That's absolutely normal. Don't worry.
Yup happens to mine too. Heats up quite a bit and then cools down after a while
Clean your charging jack once with hot gun with paste.
Sent from my E10i using XDA Free mobile app
No need to be worried then as its common for everyone. Thanks.
It's completely normal, phones from ~2-3 years ago (before quick charging) didnt have this problem because they didnt have to dissipate the heat generated by forcing 15 (moto Z) to 25 (moto X) watts into the phone. Phones pre-quick charging only took in ~5-10 watts which is much easier for a phone to handle, although its also much slower. If you dont need to quick charge I would recommend using a normal power brick which will charge it slower, but also generate less heat. Some people think the heat can cause the battery to lose capacity quicker, while manufacturers say it doesnt. Honestly I dont know which is true so I cant say. I personally so far have charged over night on usb (~2.5 watts) and its done charging my phone and my moto mod by morning from <30% to 100%.

No need to worry, that's completely normal. The phone turbo charges until it hits the 80% mark, then the turbo stops and until 100% it charges normally, like any other phone, so it doesn't get hot. During the turbo charge it's normal that the phone heats, as it uses more power to charge faster, and from 80 to 100%, it begins to cool down, because it uses less power to complete the charge.
Normal
compared with x style
z play is nothing:laugh:
A potential work around
I realized that if you remove the back cover (style mod) while charging and keep the phone a little raised from the surface the extreme heat is not experienced.
You could try and confirm.
