Hey guys,
I read all the solutions but none of them works (somebody just says to reboot the phone, somebody says that it needs a charging cyrcles etc).
I have myd esire that stops charging at 99%.
If I unplug the AC (after like 12 hours), and then I replug it again, it finishes charging at 100%.
is there something I can do?
Had you done the wipe battery states already or you hadn't done it?
Swype is ruining my life!! :|

Time for some myth debunking I see.
Hey !
Actually, the charging process of most devices is to fully charge the battery up to 100%, and then to let it be discharged as if it were disconnected down to 90%, then charge it again back to 100%, and then let it discharge to 90% and so on...
This system allows to preseve the battery's lifetime because li-ion cells (and cells in general) don't like to be charging even at 100%
there is DEFINITELY something wrong with my phone: I had the battery at 28% (I read the percentage with battery calibrator), and now, after 1 hour, is at 35% :O
Charging a battery is obviously a chemical reaction - if you unplug it, the reaction stops, plug it in and it restarts.
Meaning:
If your phone stops charging at 99 % the chip on the battery reports its fully charged. If you un- and replug it the process starts again and the battery needs some time to send a fully charged report. If you check your battery the its somewhere between 98 and 103 % of the rated capacitance your battery is fine.

Delete your battery stats, charge it an entire night. Do you use the genuine charger? If the battery is still not fully charged then its most likely the battery. If it charges to 100% - but very slowly - its your phone or the charger.

I deled the battery stats yesterday night, but nothing changed.
the battery is genuine and new!and by new I mean that I bought it two days ago...
I don't use the geuine charger, I have the USB on the wall, why?
Try charging from a PC usb port instead of a wall charger. I only have anecdotal evidence, but I find that the battery lasts better when charged slowly from my PC than when charged while plugged into the wall (true for my Sony X8, also appears to be true for my Desire which I've had for less time). It takes probably 5 times longer to charge on a PC vs. the wall plug which I assume has something to do with it.
If you're on rooted sense rom, there are kernels which support USB fastcharge.

So my s2 has been charging really slow, like today it took like 5 hours to fully charge, and when connected to charger if I'm using it it wont charge very well, like the battery will stay at lets say 20% when im using it and charging it, it might even go down more. it used to charge pretty well even if I was on it. Cuz this be the charger, or is my battery messed up?? Im using the charger that came with the phone.

Are you charging through a usb port on your computer or ac? If it is with usb port then yes it will charge at a much slower rate. Also if you have a lot of apps running or backround data going it will also cause your charging to slow down some. I would say through usb without any apps open and backround data stopped It would take a few hours to charge say from 20%. Through AC in the same condition probly 1.5 hours. Try to reboot your phone and then plug it in to charge to see if that doesnt speed it up any. If it does then you know you have backround data moving at a fast rate and that would be your reason to slow the charge down.
Yeah I'm charging with the wall charger, not thru usb

You could try calibrating the battery, maybe. To do that, turn the phone off. Charge to full (make sure it's full, by taking it off of the charger and putting it back on...the indicator should read 100% almost immediately when reattached to power).
When the battery is full, with the phone still turned off, remove the battery for about 2 minutes. After 2 minutes, reinsert battery and restart phone.
Battery will be calibrated. This may not resolve the problem of a slow charge, but will clear 'battery memory' which may have been preventing it from charging completely (and, I suspect, may have inhibited charging).
Good luck!
I was using an aftermarket wall charger and had similar results. Switched to the USB/AC converter that came with the phone and all was well.

Actually, one doesn't need an app to calibrate the battery. If you follow the instructions above, the app is unnecessary. And the phone mustn't be rooted

Hey elflip88, have you found the issue yet?
I have the same problem on my HTC Amaze 4G. It's charging 1% every 3 minutes (adds up to 5 hours)
I'm also using the wall charger...oh damn, I'm starting to think I have a faulty device / battery...
yelp!
For the record Samsung devices are known to be slow at charging so with that considered.... You still shouldn't be at 5 hrs. I would find a battery stats app charge your battery over night and check the chart to see exactly how long it takes to go from 0 - 100. Make sure your batter status is good. Also check the voltage coming into your phone from your charger. There are plenty of battery stat apps in the market that will do this sort of thing. Of course make sure your battery doesn't have water damage of course too lol.

I've had the same problem with mine. But, I can get 1.5 days without charging and moderate usage. Charge it up, drain it, charge it back up then wipe your battery stats in recovery.
This may help if you're using an aftermarket wall charger
If you guys are having issues with slow charging using an aftermarket wall charger, it could be that the phone is charging in a USB state rather than an AC charging state. QuickCharge could alleviate your issues. The cable is inserted between the wall charger and the USB cable that goes to your phone. You can find the product on Amazon. It's the 2nd of 3rd item from the top when you search 'QuickCharge'.
I find that when I fully drain my battery and charge it, it's really slow. Once the phone has enough battery to stay on, I unplugged it and replugged it and it charges normal again.

It's your wifi and your apps using wifi. Turn wifi off while charging. I used to charge 4 hours + on my S2. Reduced to 2 and some change when I turn off wifi.
Also, I struggle to make it through a working day with wifi on. Turn wifi off and I can do 4 days no problem.

I'd like to check if its safe to leave my phone charging for 7+ hours. It will be nice to leave the phone charging as I sleep.
But without a timer this would easily mean 3+ extra hours of it being left charging when it's already fully charging.
Will overcharging on a daily basis lead to any problems?
Thanks.
No. Charging overnight is fine.

The phone stops charging at 100% and lets it drop to 95% before starting to charge again to combat overcharging.
Many thanks.
Thanks given to all 3 of u!
So u people say that custom Roms can be safe when we over charge
By automatically stopping it or discharging a little bit.
I use a galaxy note.however replacing it with a htc one...
I won't mod them by installing custom Roms and all..
What if I do the same wit it now?(overcharging?)
Its the same for stock.
Its not possible to overcharge it. And the ROM you are running will have no effect on this behaviour.
Its all controlled by the charging circuits inside your phone.
They read the amount of millivolts that your battery is giving out.
These are not exact numbers (just an example)
Low battery - 800mv
You put it on charge
When your phone reaches 2000mv - full battery
it will stop accepting voltage in
While it is still plugged in your battery can fall to about 1940mv at which point it will start charging again until it reaches 2000again.

Ok cool, I see. Despite what you said above, I also have been doing this for a short period but when i get up in the morning, my htc one m8 are hot at the back. When i remove the charger the heat disperses. Can you tell me if this is normal? Also my phone are using 4.4.2 which is not the latest update.
I noticed my GN charges until 100% or "fully charged" (battery widget that spells it out). Shouldn't it be 97% or 98% max when charging to prevent damaging and preserve longevity of the battery? Or is this some new thing with 4.04 that it'll tell you 100% when it's really 97%? I do notice it drops down to 99% really quickly.
I'm stock on 4.04 and I'm using the provided USB cable and charger plug.
Thanks.
I take it you came from a Nexus S before? I was surprised too but I believe it cuts off the charging to prevent overdose of electricity. No worries on it mate.
It will charge to 100% of what ever value you set or as default comes.. Like you can see on the screenshot

Not everyone uses that.
The way the battery works is it charges to full, then takes itself off the charger until it goes down to say 95% and then at that point it goes back on the charger until it's at 100% again, so on and so forth.
Using custom ROM?
Maybe you need to calibrate the battery after you flash new ROM

Wiping batstats does nothing.
so basically it is safe to just leave it plugged in all the time then, the phone by default is DEFINITELY stopping charge at 100%, Correct?
because i know 2 facts about lithium batteries which i learnt today....never leave it permanently charging. and never let it drain fully all the time (the 40-80% charge rule).
im just worried that if i leave it plugged in it'll continue charging even when its at 100...
Do you know if - with that different kernel/ROM - whether you can set it so that you can leave it plugged in - and it won't charge past say....96%. And when it reaches that limit, it lets the battery drain back to say 40%. Before charging again - any software that will let you do this?

Is how phone even on the charger that long..? Something like over night won't kill your battery. The software is supposed to tell the battery when to take itself off of the charger and when to go back. You can use a kernel that will let your battery ONLY charge to a certain percentage.

You do know todays chargers have technology in them to prevent this right? They have for a while, overcharging is mostly a thing of the past, unless you buy cheap, flea market chargers.
in Recovery Mode there is an option called "battery ststus calibration" (something like this which I cant remember) . actually any percentage of battery use can be "calibrated" into 100%, the number is not important.
Okay, as long as charging up to 100% isn't damaging my batteries.
I did come from a Nexus S, and I always thought that when it stopped charging at 97% that was a good thing to prevent damage to the battery. So naturally, when I see it's going to 100% every night, I imagine it's damaging my battery.
Thanks all.

You cannot calibrate your battery. You can condition batteries. Wiping battery stats and so called calibrations apps do absolutely nothing.

That's just because that's how the nexus s battery driver was written. The galaxy nexus driver isn't written with the 95% recharge limit. Its OK though there's no danger whatsoever leaving the phone charging overnight.
i mean, the feature is included in some of the GN roms

I think you'll fine but it will take longer time to charge as the Note charger has higher amp
Charging slower is fine, just don't want it to stuff up / shorten the battery life.
Just that I've being feeling that my battery seems shorter standby/use time now..
Maybe becoz started using google now?
Also is there any ways to maintain the battery life? Does discharging still work?

Hey
To my knowledge its best to charge these new batteries often... it was in the old days that it was best to let the batteries discharge completely, before recharging... I've heard that this might even harm the new generation of batteries...
- Bobo
Yes I came across the same info when I was using my HTC one x --> charge as often.
So same for our SGN2
= charge often, no need to discharge method.
Now can anyone confirming that google now drains power more than expected?
Somehow I was getting more than 1 day of life before but now with same usage my battery can bearly make it to the next morning?
If you want a fast charge, find yourself a Nexus 7 or Kindle Fire HD charger.

Thank you, the battery life depends on repeatedly charging and discharging frequency, so should try to avoid more charge when the battery power, this will shorten the service life of the battery. Mobile phone off time more than 7 days, should first will phone the battery to completely discharge, enough electricity before use

No that's just wrong!
Phone off, leave the battery atleat 50% charged.
Do not completely discharge the battery if you can charge before it's 0%
It was true for NIMH batteries, but it's a long time since we had those kinds of battery, and ofcourse NiCd batteries.
yep, what rvenes mention should be the go = no need to discharge (drain battery to 0 and full charge).
simply charge as often as possible, not letting it fall below 50%.

Any chance the original wall charger is being stopped before it's fully charged but sayin it is?

Battery stats wiping is not a thing. It's a myth. This happens every time you unplug the phone when its' above a 90% charge. Most battery stat wiping apps don't even do anything. They just say they did something. Even if you did wipe battery stats, it doesn't matter. It's not a thing.
The charger doesn't have voltage cutoff. So the charger isn't purposely stopping the charge. The phone itself does though. What ROM are you using? Have you tried with a different ROM?
Thanks yeah that's what I've been told but other people say to. I just wanted to say it so it wasn't advised I do a battery stats wipe ha. And yeah I've tried a few roms same situation I'll give it a few more runs through the batteries to see but it definitely burns through the battery in about half the time after full charge via USB rather than external charger
