My phone has 50% battery left. I plug the cable into my laptop to charge over USB. Then I play some games at the same time. The battery level comes up slowly.
So is it good to do that? Or we should do one at a time: charge or use phone.
I have always done it that way and ive had android ever since it first came out. Nothing should go wrong, at least not for me.

No problems with that.

Yeah this is a good question I have always wondered about it... Won't it affect the battery like long term?
Wont harm anything
it doesn't matter if affects to the battery or not, you will trade your phone for another new one before the battery gets damaged
The only issue is that the phone will heat up like crazy so...
If you're overclocked or it's a very hot day, please avoid doing this, otherwise you may damage your phone.

Does anyone feel charging in power off stage is quicker than normal stage?

Of course it is. One is "In & Out" while another is "Only In" >>> The battery is filled faster
@Everyone: I wonder if it will affect the battery life. For example, its capacity is reduced faster

Using while charging overheats the battery and the mobile itself.
Heat is the biggest enemy of batteries (wrt. longetivity), so yes it does reduce battery life. Having said that, most of us upgrade phones in less than 2 years, so it wouldn't be as much of a problem.
But overheating is not good for rest of the phone hardware.

I really doubt that. If the phone or battery were overheating, you wouldn't be able to touch it.
Maybe it reduces battery life, but that can't be much, since the battery gets hot whether it's being charged or not.

If you left it in all the time, yeah, that would.
Using it while charging is fine. Mine charges at about 30-35*C, gaming on top its up to max 41/42. Thats well within limits and its going to have negligible effects on the battery pack.
What charger? Sure it was an dealextreme charger.
Logic.

Well, as the title says.. today I've charged my Xperia S from 5% to 100 and yea i am sure that the charger is the EP850
to my problem:
the phone takes about 20 minutes to get to 18% which makes 13%/20 minutes which means that the phone takes about 2h30 to fully charge up and i don't consider this as normal...
anyone facing this? and got a solution?
The thing is battery change level is not linear. So you can't assume 5% to 18% in 20 minutes == 13% / 20 minutes. If the device is new, it will need at least 5 recharge cycles to calibrate properly.

Do you have alot of apps running in the background ?
Cuz that also uses power
if your phone is using power, connection to internet/gps or whatever, or syncing stuff, it will also charge slower.
Well i got the sync on but at night i put all background data off so that cant be the cause..

Probably they got it wrong. Fast charge is supported and my source at Sony confirms that:
Sent from my LT26i using XDA
[email protected] saying that the S doesnt support the fast charging, even on my Box there is a sticker with this on it : 10 Minutes charging = 60 minutes of phone calls so yeah they might have got something wrong there.. but still this is bugging me.. Ive tried a factory reset with restoring apps and still it doesnt work :-( im beginning to think that there is something wrong mit my S' hardware :/
Sent from my LT26i using XDA
What Markus is saying is right, you are mixing your technologies up and there is nothing wrong with your hardware.
All charging starts with the highest current so 10 minutes charge will give 60 minutes of calls if you live in the lab, Sony wont give you the worst case figures or they would have told you your S would be flat in 10 hours. As K900 pointed out charging is not linear, it starts with a whump and tails off as the battery gets fuller and fuller, if it didn't it would boil the cells.
Hello!
Lately I've been suffering from a battery problem, I will explain what happens.
I charge my phone completely and then I start using it... when it hits 30% left, the next drop is 20 instead of 29%. For example... If it takes 3 minutes to go down from 84% to 83%... that's the same time it takes from 30% to 20%.
It also happens when it hits 14%, instead of dropping to 13% it drops to 4%.
How can I fix this? I've been told that it's an issue of flashing too many ROM's
Actual ROM; Carbon 1.7 Stable version
Previous ROM: D-WIZ JBX.
P.S: I've been facing this issue for months now, I think it started with D-WIZ.
Thanks
I am also having these problems yesterday i flashed aokp rom it all went well but today it was showing 70% and as soon as i put the mobile data on it showed 49%

I've had the same problem and I cannot seem to find a solution. My battery also INCREASES from about 80% to 100 when I'm charging an almost dead battery
Why don't you guys calibrate your battery once . Let me know if it works or not . If not then ill look out for something else.
Please hit the thanks :thumbup: if i ever helped ya !!
How old is your phone.?
Its common for old batteries to incorrectly display battery data. This simply happens because the battd daemon uses the estimation based on checkpoints and voltage of the battery. When the battery gets old, the actual charge stored is less than the reported value and results in wrong calculation by battd.
If your device is pretty old, it is in a sense normal. However if its new then it might be some problem.
PS: The battery calibration is a myth! The /data/system/batterystats.bin file is not related to battery charge/life/status (exactly as Google devs stated earlier).
In case of our Razr, charge the battery to 100% and keep charging for few hours after that. Then disconnect it battd will display correct 99%. That's all you need when changing ROMs or batteries! Do not waste your time on "battery calibration"!

What I usually when I switch ROMs is I will both download battery calibration, and keep the charge at 100% for a couple of hours after. That way there is no doubt that it truly is at 100%, and Battery Calibration can do the job well hope this helps!

I wouldn't consider it very old. I think in your case it can be fixed. There were some files that needed to be replaced. don't remember it exactly but will look into it.
Mine does this to. Not sure if there are dead battery cells or if its associated with rom.
Having this issue also calibrate don't help me unless I'm doing it wrong..... RAZR maxx

Then buy an ICrap or old BlackBerry and get a swirl... live free with equally fast discharge...
Fast charge is disabled by default (on obvious reasons, google it), but hey... anyone is free to make it work if he can find a proper solution.
Said that, 3 hrs should be more like 2 hours or 2 hours and a a half... but seen OP never stated specs, it's all right.

Yes I am , thank you, cause the slow charge issue was elaborated and mentioned so many time around XDA but seems no one cares to search and read.
This phone with and with original charger, and AFTER teh update from Gingerbread to ICS/JB is charging as per specs. On Gingerbread there was a flaw that permitted to charge it upto 900-1000 mA but the phone was rather hot, I recall charging mine in an hour and a half or 15-20 minutes more, from 2-3% to 100% back when phone had GingerBread.

You can use 2.1A output chargers too, it is simply not going to draw all that but you might get the better on the go recharging while you're using the phone with heavy apps. Just think of the dual car chargers - they have both 1A (phone) and 2.1A (tablet) output. SatNav on 1A is zeroing or still draining your phone battery, while 2A can slowly charge it on the go.
You just give it a needed juice and if the discharge is so greater then recharge, there's not much you can do about it.
Call it a flaw, but Samsung did it cause of longevity of their batteries and li-ion technology.
That is why I indicated iCrap and BB - their fast charge is provoking rather fast discharge too cause the battery will not hold it. I have colleagues with BB who're charging in an hour but get their phones depleted in 3 hours of usage... I wouldn't want that from my S2 for sure. :good:

It doesn't matter what the output current of the charger is... the phone will only draw 650mA.
The charger I got with my S2 delivers 1A but my phone only draws 650mA. Actually the hardware doesn't support it.
IMO, 3hrs is pretty fast for a full charge.
Edit: Just noticed that Fevves already mentioned all that...
adressing sfafrorn
Some kernels have the Option to change the charge rate but even at 650mA the phone will get very hot if you are doing something on it while charging
Sandm4n is right :good:

Not really. Just don't let it overheat.
Try charging while your phone is off and see how long it takes. I'm sure MM running throttles the charge rate or its heavy cpu usage while MM is running. 4-5 hours is looong. Sure mine takes no more than 2 hours while running on LP.
EDIT: OK maybe I exaggerated a little, mine is closer to 3 hours after testing on LP.
