Is it bad to leave phone on charger?

I have seen different opps on this.. abotu leaving it plugged in all night..
I just was not sure if it really matters, or hurts the phone? I leave it in all night and just unplug in morning when i get up.. Is that bad or what? I jsut want to see what everyone else thinks about it on here.

There was another thread exactly like this a month ago. The answer is no. There is circuitry and scripts to stop charging.

Thats my Plan!

I've heard this too. My ex girlfriend seems to think that it actually causes the battery to swell and inflate, causing it's eventual demise.

This was the case with older batteries and much older phones all modern phones protect against this. I still unplug right away out of habit though.

As a note:
When the phone charges to full and your little blue light comes on, the phone enters a state of constant discharge and recharge. Meaning that if you leave it plugged in once fully charged, when you finally take it off the charge actually may be anywhere between 95-100%.

ya on my stock battery i used to see it at 92% some times when i would unplug so i had to replug it in and re charge a bit at one time when it got full it would stop charging completely and id wake up with a empty battery thanks god that was fixed. and i just got a much bigger battery

I picked up a cheap wallcharger and spare battery. Charges to 100% and stops. It's beautiful.

HTC One X fine last night - dead this morning

Morning all,
I run:
rooted HTC One X running Renovate ROM
this phone is one of the faulty batch with the dodgey wifi issue
I have repaired the wifi issue
the phone has been working fine for the last 3 weeks
I plugged the phone in to charge last night
this morning it is totally dead, there is no charging light when plugged in,
I did notice that the phone was running very hot last night
phone is on T-Mobile UK
any ideas?
suspect the phone overheated and it cooked the battery

Sorry to hear that, I don't think it's a good idea to charge it through out the night. Can you still feel the heat of the mobile?

It has happended to me !!!!

No need to worry, it has happened to me a few times. remove it from the usb, make sure you plug it back into the wall charger and hold the power button looking at the LED on the top, it should go red. if not just press it and wait a few times. I know it sounds crazy but it has worked ever time. once the LED comes on, just leave it to charge.
My fix was to update my clockwork to 5.8.4.0 that fixed the USB isues

Thanks everyone - I rooted last week so I'm already running clockwork 5.8.4.0
I plugged it in the OEM charger and into a known good socket (house is 150 years old and some of the wiring ....well...)
anyroad, I left the phone for an hour and when I returned the amber charging light was on and it was showing 63% battery.
I think I might have the problem diagnosed. I keep the phone in a 3rd party leather wallet which also has space for cards and money. I usually charge the phone in this with no problem however I suspect that the jacket caused heating issues - the phone was running Audible for Android last night, and the combination of all caused the overheating.
In future I will remove the phone from the jacket before charging overnight
phew!
and thanks to all for your assistance!!:good:

Every phone I've had (Android, WM, Symbian) has been charged in a dock overnight and I've never had battery issues...

This is nonsense, it does no harm to keep it plugged indefinitely.

Same thing happened to me. Plug it to your computer with the USB cable (not to the AC charger) and let it be for 15 minutes. At one point, it will start charging. Then leave it for another 30 minutes before switching it on.
What happens is that it goes crazy and instead of charging starts to discharge, and when it discharges completely it will not even boot into the charging mode or respond to power button.

Don't comment, if you don't know it completely. Just take time to read this article and decide. I won't get anything if I say something like this.

This is called FUD.
1) Modern Li-Po batteries don't mind being charged to full (damage occurs above 4.23V)
2) they don't mind temperature (to some extent of course)
3) they don't need to be discharged (yes, it can mess calibration, but it also wears them out)
4) all batteries in consumer electronics are protected, so even if the charger/phone does something stupid, they should not be harmed
5) battery explosions and fires are caused by mechanical damage or a short, charging circuit malfunctions are very uncommon
6) when you leave it plugged in, it will not harm the battery, though it depends on device what happens - the device can run from the charger and let the battery be, or it can run from the battery and start charging again at ~95% (this is what lenovo laptops do), or it can keep running from and charging the battery (this is what a HOX will do IMO). Everything but the first case wears the battery out, but it's so minor that you won't notice it at all.
This article was written for sake of having an article, it's full of misleading and incorrect information. I don't need to be a battery expert to notice that.
In short - your phone knows what to do.

Guys whatever you say but i had Samsung galaxy s before and its battery died because i used to keep downloading on atorrent all night keeping it plugged. Though battery was cheap just 10$ so no problem but htc has non removable battery plus it would be costlier i guess 30-40$ so i would recommend not to keep it plugged for too long

And the other Samsung galaxy s you had, which you treated identically, apart from the downloading and charging all night didn't suffer battery degradation, right?

Nexus causing old and brand new batteries to drain while charging - Please Help!

So I have a CDMA Verizon Nexus running the latest version of Bugless Beast. It's been working great for a week now, but today it's had the craziest problems.
I forgot to charge it last night, woke up to a dead battery, so I plug it in the charger for an hour, but it stays at 0 percent. It never charges at all. Then I unplugged it, the phone dies, and it can't charge at all. I take it to a Verizon store, they swap it for a new extended battery, and it boots up the phone, showing it was a battery issue.
After I come home with the new battery inserted, I notice the battery is draining again even with the new one and it's charging again.
I tried to wipe it and recover it to stock so I can see if the issues are the same with stock settings, but of course, the battery died in the middle of it all.
Has anyone had issues like this? Thanks in advance!

Try a different charged are you using the stock charger and extent ion cords?

Sorry, forgot to mention that I was using the stock charger and have tried other chargers for different phones laying around the house. When I took it to the Verizon store they also tried different chargers before replacing the battery, but it wouldn't turn on. Swapping it with a new battery worked temporarily, until it started to drain again even with it charging using the stock one.

Do the battery stats provide any useful info?

I unfortunately can't check them now because both batteries are spent and the phone won't charge them, but if it helps at all, I noticed that it would have the charging icon on the battery when plugged in, it would say "charging" on the lock screen, but when i would check the battery stats,it would go against all of that and say "discharging" instead.

Just for my understanding: the phone is off, you charge for a couple of hours, the phone does display the charge icon when you plug in a charger, but if you try to turn on the phone after a few hours of charging it's still dead?

Almost all correct. When I say charge icon, I mean the one in the top right corner of the screen when it's actually on. I've never been able to get the black screen with a charging battery to show up at any point.
Say I have a battery that has about 35 percent juice left. The phone will be on, and I'll leave it in the charger. It will say its charging, I can operate the nexus just fine, but according to the battery stats in the settings, it's actually discharging while it's plugged in. Once it hits zero, that battery is useless.

Correct.

In that case, I doubt there's anything we (you) can do. I'd return it to the store.

That's what I was guessing as well. My only problem is that since it's rooted, the warranty is voided, so I can't get a replacement phone. I had come so close to bringing it back to stock and unrooting it with its last bit of battery, but it died right in the middle of it attempting to re lock the bootloader.
At this point I think I only have a few options...
1.) Buying another battery from Verizon so I have some juice for the Nexus to finish up the bootloader issue mentioned above, bringing it back to stock, then bringing the phone in to replace it.
2.) Just say I lost it and hope for the best that they'll give me a replacement one. I bought it off contract from a third party vendor which probably won't help my case, but I am insured by Verizon on the phone, so it may just work.

A third option could be lending/buying a charger that allows you to charge your battery outside the phone. I think DealExtreme sells those. Shipping takes a while though. Anyway, good luck. Hope you'll get a replacement.

Option Number 2 may not work out for you, do you have insurance?

Brand New One X - Dead?

Got my One X in the post today, plugged it in, been on charge for atleast an hour and a half but it's still dead
No signs of life, no charge light, can't turn on, can't enter bootloader
Anyone experience this?
Also the phone is stone cold, if the battery was charging I would expect it to get warm...

Yeh looks that way so that means no new phone for a week as I have to wait for them to collect it then send me a new one, can't just take it to a store which is stupid
Checked the pogo pins with a volt meter and it's reading 5v no problem so power is getting to the phone it just seems dead. No battery life and it won't turn on

When I got a replacement HOX from carphone warehouse that was dead too, but I left it plugged in for a few hours and it came to life.
If the battery has no charge at all it may seem like a fault.

Charger that came with it but checked dock pins to make sure voltage is present in the phone which it clearly is

Does sound dead sadly, should have some charge if it came new.
Does it get detected as anything by windows even if off?
Any repsonse if you hold down the power button and both volume buttons?

Mine did the same thing when it was fresh out the box. I just left it on sharge for a couple of hours and the charge light then lit and it powered up. The battery was just very flat on arrival.

Did your battery warm up though? This ones cold to the touch
I think it's dead so already called for a replacement but gotta wait for it
In the meantime I will leave it to charge overnight but I'm not hopeful at all, be better if we could access the battery instead of HTC going all apple on us

As I got my hox, it was fully discharged too, and it took ca. 30 minutes to bring it back to life...
Sent from my HTC One X using xda app-developers app

When I first got mine was at 15% battery, after 24hrs charging (original charger, laptop, Inc s charger...) nothing changed.
Ended up with a replacement but took optus Australia 3 weeks to replace it.

...
Try to change cable I have to do that because stock cable that came with phone is sh..t.One day just stop working.Now using NOKIA CA-101 and no problem at all fantastic build quality.With stock cable had that problem couple times

Even if it does not light right up, the battery should get warmer when charging. Like advised, try a different cable, if that does not work either, then there probably is no simple solution that you can solve on your own.

[Q] Nexus 7 turns off

Hello Everyone,
I am a noob on XDA, Please correct me if i have posted in the wrong forum. I bought a new nexus 7 16gb, for some reason when the battery is around 25-30% the tablet turns off itself. Its not shutdown its like pulling the battery of a phone thats on. The only way to start it is by connecting the charger.
Has anyone else experienced this issue?
I am on the stock rom NOT rooted
Thanks

Have you charged the device to 100% yet? I would do that, leave it charging for an hour after it shows 100% then use it till it dies. Rinse and repeat.

Yes I have charged it 100% multiple times, The only difference is i use a sammy charger that outputs 0.7 amps once in a while. I dont suspect the charging thing to do this.

Are you getting normal use out of a charge? How much screen time in one charge?

Like Highfigh suggested check how long you can run on a full charge. If you get some good hours in then maybe the battery % is not reporting back properly. A reset/restore could possible resolve that issue.

I believe I am getting pretty good charge. I will try once again, I was thinking this might be something with stock rom and hence I posted it online. Thanks every one for the help

exactly the same story here. in my case it's not so easy to turn it on. it would seem like the device is completely discharged, even if it just showed some 40 % battery left. i have to wait several hours to even try to bring it back to recovery mode. very long press does nothing. it happened couple of times already. very annoying with such seemingly superb tablet. i'm not living in the us of a, so no quick replacement for me

That's bad I can turn on mine in a few minutes. Again mine happens very rarely. I also get an excellent battery life. How long does yours go on a charge.
I would also like to know if there is any kind of Logs that we can look at. It's getting irritating, did you try rooting your device to see if that might fix the problem.

I got the same problem recently, I think it was after the last update on the firmware. Everytime the battery reach around 35% it just went off.
