Is the iphone power supply useable for charging the S5 using a Dell cable?
The Voltages, Currents and Connector (both USB) are the same.
same like i am using original samsung galaxy tab charger.. i am on high speed charging of 2000mah by the way...
Am also using samsung tab 7.1. Charger.......

completely empty battery.. approx 2 hours.. if not around 1 hour...
use a 5V 2A charger should do the job...
once it goes 100% .. let it continue charging around 1 hour ... the battery can last more than 3 days for normal not intensive usage...

OMG ... 3 days ?? are u using stock battery or other replacement battery like MUGEN? And how do U use the phone? Are 3G on? Are U have online apps like whatssap installed on your phone, dude its really surprise me when U say 3 Days... :thumbup::beer: since mine need to be to charge twice a day (with 3G only always, and some apps with push notification)

lol.. i am on stock battery but using it on power saving mode..
like your usage, it is more above average already...
What do you mean by power saving mode?
Not maximum clock but normal use?

power saving mode = turn off everything that consumes battery
overclocking always consumes battery because of high performance ...
Do you use underclocking?
(Clock lower than stock max)
nah.. just default clock... by the way.. if i see some application that uses max default clock all the time.. i use setcpu to underclock for that particular application... say half of default clock...
results = less battery consumption for that application...
which program do you use to find out which app uses cpu power all the time?

Hi,
I found a compatible with BST-38 (for the mini pro) Li-ion 3.7V and 1420 mAh (my phone battery is Li-Po 3.6V and 970 mAh), do you think that can be "dangerous" to use one of these batteries? (The brand name is Jin Dian and what worries me is if this difference of 0.1V can damage the mobile, whether it will be more or less good in general) You can see it on ebay (220676929621).
I'm just desperate because I tried autokiller, setCPU, advanced task manager, juicedefender, etc. (droid wall and Wisync didn`t work properly in my phone), but my battery dies in less than 15 hours...I need a solution!
Thanks and sorry for my poor English
15 hours using it how? full? idle?
SE says with android 2.1 the battery life will be increased 200%, maybe before to burn your phone you should wait a couple of weeks and try if it is true... xD
15 h with data connect on for k-9 email, but without BT, wifi and a couple of calls.
I bought the same battery and have been using it for the past 4 days. To be honest, it lasts about the same as the stock's. Maybe with a few more cycles, it would last longer.
But does anyone know of any app that could measure the mAH?
There is a BST38 battery with 1930 mAH selling on eBay but will burn a HUGE hole in your pocket!

Have you tried using other launcher/homescreens? Mine lasts 24hrs max before, now it lasts 30+hrs (with helix)
I used to charge my phone every 2 days. I used it mainly for calls, sms and internet. I dont stay more than ten mins each time Im online which could be 2-3 times a day. I dont have bluetooth, wifi and 3G switched on. But lately the battery life is dwindling...maybe cuz I have more apps now...sigh.

Have you do battery calibration right?
Use your ace until the battery getting low, then wipe battery stats, and use your ace until it turns off by its self. Finally, charge your phone (power off) 'til full. Do it twice.
I recommend you to use battery calibration app. Get it in market.

Then try flashing stock rom. If the problem still persist, I guess there's something wrong with the battery. Buy a new battery, or if you're not sure just bring your ace to Samsung Service Centre and let them see the problem.

I just bought another battery. I found it was the battery more than port problems or anything like that. My friend and I have the same phones, same roms. We tested this by first going through 3 power cycles. After we charged it, we had only the same apps working, except for some minor checking of FB and twitter (I don't use twitter, but he does).
After our 4th power cycle, it seemed like his phone was dying faster w/ my battery in it. His battery in my phone lasted about 5-10 hours more, I did my normal daily activities on it, even played some youtube videos in class.
So I bought a new one, and bam, stays alive more than 12 hours

Common sense post of the day:
You have to be really careful getting phone accessories off e-bay. In the past I've been duped into buying a fake SD card and a wonky battery.
I been having weird recharge issue since i moved from VIKING V5 to Omega and now to PA3+
Phone recharges at optimal power , ie 900mA/h over USB 3.0 and 1000mA/h over wall charger.
But It recharges the battery at slower rate ie about 50% over 3 hours.
small detail here : http://forum.xda-developers.com/showpost.php?p=44067907&postcount=3631
Please can someone help me fix this issue.
Let's analyze a little bit.
What part the recharging involved?
1. Power source, USB port or wall charger
2. Cable
3. The battery
I suggest you try use other cable or power source. Also use current app to see what's incoming current.
If it show normal current around 900 ~ 1000 mA and yet you still recharge slowly. Perhaps you may wanna try other battery...
Normally for me with 800 mA current, it take me somewhat around 3 or 4 hours to charge to 100%

1.) USB 3.0
2.) Samsung cable , which came with the phone
3.) Same samsung.
I used an app , it showed incoming is 900ma/h .
Many suggest to change the cable. Which one to use ? Any suggestion ?
OK found that my phone is only taking in 500ma/h even though incoming current is 900(usb 3.0) or 999(wall charger).
What to do and how to solve ?

Are you using that current detection application we have in general section?
Galaxy charge current, if I remember the name correctly.
If, you are able to determine the incoming current to your phone, and I assume that is real value, then you can do some basic mathematical calculation.
In your case if it is 900 mA , our battery is 2100 mAh, then the full charge time should be around 3 hours (phone in idle, because heavy task might drastically effect on the charge time)
If your power source and cable are all fine, and charge time is much more then 3 hours, then the problem probably in the end of battery. You may wanna try other battery.

You seem to be over worried.
Let's do a math here
Assuming 900 mA output, battery capacity is 2100 mAh
2100 mAh / 900 mA = 2.34 h.
Of course is this totally theoretical. Consider the device power consumption, cable resistance and battery natural property (charging rate become slower when closes to the fully charged, means last few percent is taking longer than usual due to battery natural property and some additional battery protection )
Consider these various factors which slows down the charging rate , 2.34 hours in theory, so it is OK to use somewhat around 3 hours to get battery fully charged.
And I'd say it is average, between 2.5 hours to 3 hours.

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.

ill never buy an iphone,s2 does charge really slowly and s3 too,but s4 no,so its a matter of samsungs technology which is slow,plus i agree that battery is good for 1650,i guess ill have to get used to it.Im going to send it to samsung to see if they can change something,like the usb port to handle more voltage,do u guys think its possible?

Nope, they won't do anything, but you can try all along if it's free service.

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:

With stweaks you can let usb charge from 450 to 650mAh.

But it risky for USB port!

Use s4 charger. It has 1amp output current. .
But not recommended though.

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...

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:
