I plugged in my to charge my phone at near 25%. I let it charge till 100 and used the battery recalibrate tool. Once I removed the charger the meter went down to 49% ....lost 51% just like that.
Guys please help.
I seem to say this a lot, but we need more information. What ROM you're on, how old your battery is, what kernel you're using, is it a stock or OEM battery, is it an eBay battery of questionable quality, are you using any battery mods, what voltage settings it showed when you reached 100% charge on the charger, are using the stock charging cable with wall charger or a 3rd-party USB cable or charging from a computer or PS3 usb slot, etc etc etc...
With what information we have so far, try bump charging.
I on phillipe97's Juwe's port with bullet kernel. The phone was bought in March 2011, never changed. No battey mods. Not sure of the voltage it showed when it reached 100% Stock wall charger
What is bump charging?
That's really strange. Are you running a gingerbread rom? I know gb roms have a problem with the battery draining after charging to full even with it still plugged in.

Bump charging is charging your phone to 100% with it on, then turning the phone off and charging it again to 100%, then turning it back on and doing the same until it stays full when you unplug it.

Darn it, LazyB! You're too kind! I deliberately didn't explain bump charging because I knew the OP would be too lazy to do a simple Google search, so when he came back to the thread with some badly worded and not particularly useful response that contained, "What is bump charging?" I could say "OMFG Google it you twit!" and then link him to something like

But no! You had to be all nice and altruistic and ruin all my fun!

Haha sorry I must admit I've been jumping on the noob threads being overly nice to try to help to get my post count up to 100. I'm only about 10 away. I'm a firm believer in researching and reading, reading, and more reading. I lurked on here for months before posting anything. The info is just so readily available for anyone willing to do a simple search. Sorry to steal your thunder there though.

So, after I get it to stay 100% when I unplug it will I have to keep doing this everytime I charge my phone or will the problem be solved?
Is there any way around this limit? Custom kernel etc.
It's really annoying that my phone discharges, albeit slowly, when using satnav and full screen brightness.
No, there is not. However, if you are using GPS in your car and your charger is detected as MISC or USB, you could increase that to 650mA.
Mine is detected as a charger, not MISC or USB, so I get the full 650mA but I need more current, probably 800mA would do the trick.
I wonder if fitting the new Samsung extended battery would increase the charging current.

No, it would increase battery life due to higher capacity, but not the charging current.
You could resolder a resistor on the phones motherboard, but there is no software way to get around the limit.

Just to clarify so others don't keep spreading it, trying shiyah (sic) kernel with voltage control will not change anything, you are limited to 650mA.

I looked at that but, apparently, although it shows a 950mA option, the phone still won't draw over 650mA.

So it's hardware limited, how stupid .
My main use for a smartphone is satnav and one that goes flat after 500 miles is about as much use as a chocolate tea pot. I suppose my only option is to turn down the brightness and remember to go back to HTC for my next phone.

Assuming your car charger is actually supplying 650mA and the phone is still losing charge, you're not entirely without options. For example, you could use a lower brightness (which you already acknowledge), limit the CPU frequency/disable one core or have your sat nav application turn off the screen between instructions.

Thanks, I'll investigate the CPU options, I couldn't live with the screen turning off though.
For the future, I wonder if ICS's better handling of the two cores will reduce consumption.
You can turn mystic up to 650 from 450 which might help with the discharging while using satnav issue.
You would need a custom kernel and voltage control.

I presume he meant MISC, which you already clarified shouldn't matter (but wouldn't harm to try, if you're already using a kernel which supports changing these values).

As an additional, newer versions of Siyah kernel allow you to see the charge current.

I just downloaded a battery widget app and my car charger (2amp) is definitely recognised as 'AC' which I assume should be 650mA.
I'm using Android 2.3.6, Gingerbread XILA2, Rooted. Would Siyah kernel be worth a try?
Fast charging the battery shortens its life anyway. Slow charges are better, IMO.
I don't mind waiting a few extra minutes or buying an additional battery and cycling them, or charging them externally

But I need sufficient current to cover my satnav drain plus a bit to charge the battery when I'm driving. I don't mind replacing the battery every six months but pulling off the road to change it is a non starter.

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.

In fact, the most other phones charge with ~1A+ and they don't have any big draing issues in common. It doesn't matter which OS they run.

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:
So I woke up seeing my phone was at 58%, odd because I slept like 9 hours straight and my phone was charging during my sleep. So after I woke up I went downstairs, made some food, went back up to see my phone went down to 57% whilst charging.
So I've been doing some troubleshooting. I switched batteries, switched chargers etc. I also downloaded galaxy current charging and found out its only max 100ma, on all the 3 chargers I tried. Not sure if the usb port is jammed, always charged stable, and I can use it while charging without it charging on and off.
Using Archidroid 2.4.3. running boeffla kernel, I tried yank555 kernel too and problem persisted, didnt change any charging settings or something tho.
So how do I fix this?
Unplug charger from plug it again. I used Sony cable.?

The default charging rate is 1100mA so yours is definitely way too low. Flash boeffla kernel again and download boeffla config v2 from the play store. Then go to the miscellaneous tab (last tab) and change AC charge current to 1100 if it isn't already.
Hope this helps!

Downloaded Boeffla kernel and set everything up, works like a charm.
Only problem im having is that some chargers still dont seem to work, the phone just dont recognizes them while my Nexus 4 does!
Anyhow, sometimes the kernel settings seem to have reset and need to be set again.

Isn't Fast Charging Bad For The Battery?
That would depend on the battery's C rating. Charging at higher rates doesn't necessarily cause damage. There are plenty of articles on charging lithium ion/poly cells out there.
In my previous S7 Edge , the battery lost plenty of juice in just one year of usage ( i was using wireless charging only). Then i sent it to samsung warranty and they replace battery. Tried to find something about if could be the wireless charging that damaged the battery and found none that supported that theory.
Now, with the S8, i´m using the provided charger and cable only (Just to be safe).

Wireless is different due to the losses in the induction, creating heat, which does have some affect. But there are a lot of variables as to why your battery performance may have degraded.

Right... it seems every day someone thinks they know more than engineers in that field, battery is getting hot so it must be bad. Yet every year qualcomm and others improve quick charging for even faster charging, so unless someone actually knows something these threads should just stop.

Why would you assume its bad for the battery in the first place? Just because it gets hot? The cpu also gets hot when gaming so i should stop gaming? Recording 4k videos also heats up the phone so i should stop recording 4k video's? Constantly downloading will probably heat up the modem too so i should stop downloading? If something is built into the phone why would you assume its bad for the phone?

Hey, don't take it badly, he is just asking. I remember old batteries (for example ni-mh) if you charge it at a high current they use to live less than if you charged them at a slow one (i remember using rechargable batteries of this time for my wii control and i could test it with how long they lasted).
I think the new Li-ion (or better) batteries nowadays don't suffer from this, so you should be safe about them. They have a natural capacity loss thats isnt affected about the rest of the things. You should anyway check for faulty chargers or your battery life, remember all the test samsung makes are with their original hardware.
Regards!

This is someone not knowing what they're taking about trying to talk down on someone else.
Anyways heat has always been detrimental to battery health which is why samsung fast wireless chargers have fans built in to keep the heat low. Along with this the phone will prevent charging if it passes a certain heat threshold I believe 40c iirc and also the phone uses adaptive charging to prevent over heating of the phone with the included fast charger and charging circuit design. As long as the phone continues to regulate the charge coming into the phone fast charging shouldn't hurt. Of course with fast charging you go through battery cycles faster but this is just because you can charge it a lot more times than with regular charging.
My personal experience:
- 2 years of fast charging = battery drain between 100 and 90 very much noticable
- charging over night causes more damage than fast charging
