I always been afraid to leave my g3 charging during the night. But is it true that it damages your battery.
Should I start to leaving my phone charging during I sleep without worries?
Do it every time, with the device powered off. Power is disconnected when battery reaches 100%, so no problems.
night charge now is safe for your phone. The phone will not recharge until the battery <95% or 90% (still plug in )
I charge the phone overnight every night - with the phone left on. No issues.... As mentioned you can do this now with today's battery technology without worrying about battery memory, etc.
I have done this all the time with all my smartphones. No issues.
Just don't leave it on your pillow or on the bed as it may reduce heat dissipation. But perfectly fine to be left overnight charging.
I always leave it to charge when going to bed, but it gets fully charged only 2-3hrs in, so it stops charging as i have not noticed it heats up excessively. PS: i put it into airplane mode too.
The nice thing about G3 over many other phones (even G2) is the battery is replaceable. Even if you kill it over time, just buy a new battery. Voila.

Hi all,
I've been having issues with my phone lasting nowhere as long as my girlfriends identical one,
I installed Quick System Info on both phones, Killed all tasks.. Not only is my display duller than hers on the lowest setting using the power control widget but the voltage on my battery is 3737mV while hers is 4071mV..
Is this cause for concern?
Update, forgot to mention, this is from a full charge on both handsets.
Sounds like your battery is fu#ked!
There seems to be an issue with the way android reports the battery voltage. If I leave my phone on the charger until the light goes green and the indicator says 100%, the voltage will often report between 4.146v - 4.156v.
Upon unplugging the phone would drop to 99% and 4.125v almost immediately.
I noticed the other day that after leaving the battery on the charger overnight the voltage was reporting as 4.206v and I was able to use the phone for over 15min before it dropped to 99% from 100%.
Minimum voltage before your phone powers off is around 3.6v - 3.650v. So 3.737 is pretty close to the cut-off point. The OS is may report 100% charge but your battery is not holding charge.
I had a battery on a different device that was like this. The battery had collapsed. I could charge it for 24hrs and it would not make a difference. Within 30min of use or 1 phone call it would die.
Does your battery have any bugles, bumps or protrusions? This is often a sign of a collapsed battery.
Edit: Don't write when you're tired, silly things come out of your fingers! Soz!
have you tried to swap batteries between the two phones. That will exclude either your phone or the battery from being faulty.
Yes, after scratching my head for a few days I did eventualy come up with the genius idea of putting the battery from the other phone into my phone!! and after charging it up, set it down for an hour and then checked and the battery was on 98% !!
So it looks like there is something wrong with my battery, This morning I woke up and my phone had been charging for 7 hours and was fully charged, I looked at the battery meter and it said 100%, I turned the phone off then back on and checked again.. 90% ???? WTF ??? just from turning the phone off and on?
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
This morning after I got ready I took my phone off the charger (it had been charging all night and was at 100%) and walked upstairs. About 10 minutes later I turned on the phone and it was at 67% and going down. I had flashed a new rom yesterday and as quick as I could I did during the drain I did a NAND restore. Could this have been actual battery drain or is there something wrong with my phone/stats. Could my phone have stopped charging at 50% and then just said it was 100%? What should I do? Is there anyway to avoid this from happening again?! I cant go to work with a battery at 50%! lol
-.- Searching is your friend.
The Evo has never trickle charged properly. Trickle charging is when you hit 100% battery while charging and the phone will continue to keep the battery charging and maintain this 100%. So 100% > 99% > 100%.
The problem is the Evo doesn't do this. Once it hits 100%, it switches to battery. It will run off the battery till it hits about 90% and then charge again. Some even say it will NEVER charge again after it hits 100%. So when you unplug it in the morning, you end up dropping extremely fast from 100% to 90%.
There are kernels in the development section that fix this issue but there are people who say it will break your phone or burn your battery out faster over time. When trickle charging, your phone will get hot as its constantly draining and charging. That can lead to a burned out battery as time goes on or a damaged phone. I personally have three batteries. I still tried to use this and noticed a drastic improvement but my phone was also pretty warm when I picked it up in the morning. Its up to you.
Also you might want to see if you have your 4G radio on. That is probably the only thing I can think of that would drain it that fast. Either that or your GPS is on and theres an app running thats using the GPS receiver.
i'd say a 30% drain in 10 minutes is unnatural. it wouldnt be myns rls4 that you flashed, would it? this is experianced by some as a "first day side effect". just fully drain and fully charge the battery a few times and you will be fine.
It could be that it just needs a couple drains and I don't want to quickly point the finger at an app that you are using. A lot of times if I actually charge my phone it will be on 92% when I wake up. 67% is a stretch unless that was 10 minutes of a game or YouTube..but still. Drain the battery a few times and see what happens.
i was thinking maybe its some kind of battery stats problem? Could that have caused it?
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...
I plug it in to a usb cable
i charge my hox every night on the wall charger while turned on. even if it has 80% left. i am to afraid that my battery level goes under 20% (i heard that falling under that level can damage batteries).

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

Dude...
I always charge overnight - purely for convenience really.
Can you explain the above to me? I'm not sure what you mean by it interupts the cycle?
How does it effect the battery ?
Thanks alot

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.
Ebay 2m cable (the HTC one's length is a joke).
I use a charging cable.
My friend sticks it next to his head and uses his brainwaves to charge it.
Both seem to work fine.
Im really sorry for this post. I could not resist.
You guys are ridiculous. Just plug the phone in and it charges.

Hey XDA, I just purchased a new AT&T SGS3 and I'm having some issues with the battery on the phone.
When I charge the phone overnight it charges to 100% then when I unplug it, the battery drops tremendously in about 5 seconds down to anywhere from 50%-75%. I tried manually recalibrating the battery by charging it 8+ hours, removing the battery, charging again while off, charging it again while on, then restarting. That seemed to work for one charge and the battery acted the way that it would have on my Nexus S.
However charging it again after a full battery drain, the same thing happened.
Also when the phone is low on battery, it displays the normal battery messages, but then the screen stays on, draining the battery faster.
Solutions? I want the root the phone, but only after I have these issues sorted out. (I'm still under warranty right now)

Did you try a reset of the phone through the settings ? After that try charging to 100% then drain completely and then recharging without break then use the phone mormally and try to recharge only when it hits 10% remaining for the next 2 or 3 charge cycles and see if that helps
