Just wondering, our stock charger is rated 1.5A.
How come it seems that it can only charge 900~1100mA?
Many factors... Convertion loss.. Charging algorithm.. Temperature... So on

How did you measure it?
Install Ampere app from the store

Is that normal? Are your Z2 chargers also like that? My usual charging time from 10-100% takes up 3hrs+ and it really takes so much time.
Back then on my Nexus 5, using stock 1.3A rated charger it only takes an hour and a half for a 2300mAh battery.
How come it takes double. Z2 is only 3200mAh right?

If your charging is slow you could try my rev4 quick charging mod from here: http://forum.xda-developers.com/showpost.php?p=62425879&postcount=224
Also, please note that Ampere does not show you the input charge.

My phone takes eons to charge. And if I use it while its charging, it actually won't charge at all. Anyone else experiencing this?

The charger it comes with is ****. You can get 2A chargers for about $5 from various places.
Are you using the stock charger? Overall all Galaxy devices charge horribly slow down

As he said, the stock charger does not seem to effectively charge the phone well - try using a different wall USB charger. I use an old blackberry one and it works great, and my girlfriend uses her iPhone charger with the same results.
I have a similar experience. When I am using the phone and must charge I like my HP Touchpad's wall charger which can charge slightly more than the phone uses. However I bought the Samsung desk charger with the spare battery and when the phone gets to 20-30% I just swap and charge the battery in the dock. FWIW I can get from 8- 35 hours on the batteries depending on use.

may harm your s3 battery because different ampere

no it won't it will just charge faster. higher amps does not meant the charger pushes out that many, it means it can provide up to that much.
TRUE... I charged my BB 8520 from S3's charger and battery got swollen.
Thanks for the help

Nope. The device restricts the Amperage by itself to 1Amp and the charger delivers 5Volt.

i think there was something wrong with your battery.
I have charged all my devices using the ipad charger 5V 2.1A and never had a problem. i use that because with the higher Amps I can charge faster.
Using a charger with a higher current rating won't really hurt with lithium ion batteries. Some other battery types can be affected by charging too quickly.

Got galaxy s2 and Xperia play. I use battery monitor widget pro. The play charge @almost 100%\hour, the galaxy about 50%\hour... What do explain this slowness? Same charger used and battery got came capacity.

This is relatively easy to explain,
Your Xperia Play takes half the amount of time as your S2 to fully charge
My S2 from 0% to 100% takes approx 2.5 hrs to charge, so your S2 charging time is perfectly normal.

and it depens on voltage of charger aswell....650mv...faster charging...450mv slower charging...

charging time depends on charger voltage and batteray capacity..
higher batt capacity needs longer time to charge..
Not like i mentioned same charger was used and both phones battery got same capacity... So the explanation is still awaitedcc

I thought the play has a 1500mah apposed to 1650mah, the s2 charges at 650mah while the play would be.around 850mah, the stock charger is 850ma,you can't get past the s2 slow charging rate best to get another battery and a external charger
need not be the same for evry mobile
That's a good idea, i was going to buy a battery, I'll but charger too.
It's 850 vs 650 but feels more like 850 vs 400, really do slow...

Are you using an original charger?
Are you using a wall or USB charge?
I have original 1650 mAh battery and it takes roughly about 2.5 - 3 hrs to charge from 0% to 100% using original Samsung charger
It will more if you bigger battery or you are charging USB or with nonstandard charger

i use original charger and battery(1650mah) only from samsung but still it is taking more time around 4 hours.
is there any problem with my battery or mobile?
i purchased it 6 months befoe.
Bro battery charging time depends whether you are using the phone or not... because if you are using it continuously while charging screen n processor drains alot of juice...so it will take alot of time but if phone is in deep sleep it will charge faster...as simple as that..!!

Mine takes about 3.5 hours with the original charger and battery. So, depending on your usage it can be normal.
From a wall charger mine is taking around 3 and a half hours stock battery... yours seems fine...

Have you heard about undervolting and overvolting? and if you install a kernel like Siyah you can adjust the values needed to make your charging faster.

But the charging is still limited to 650mA, since the hardware only has three modes.. 90mA which is never used, 450mA which is for usb charging and 650mA which is for charging with an adapter.

about 2.5 hours here from 5%, but I normally just plug it in to the PC over night and that would take about 6-8h? at 500ma from near flat.

Here is a question for you as I brought it up above, would a slow charge from USB be better for the battery than a charge at ~1500ma on the stock Sony chargeror even close to 2000ma from a Samsung/etc charger?
I've seen about 1900ma peak on one charger
Mine take 3.5hours from flat to full.

Hmm, i know @hamdogg knows about batteries and stuff like that. I'm using the stock 1,5mAh(?) magnetic charger, and it charges my battery in about 2 hours. I don't dare using a third party (even Samsung) charger on it, since the risk of damaging the battery is too high. I'm willing to do it after 12 months though, since i have, and other have nothing to losen (warranty is gone).

It should take no more than around 2 hours with an original charger. Use either the original SONY USB (included in the package) or the original SONY 30DK DOCK. Are you using a third party charger? If yes, don't use it.
