Default Slow Charging Time

I don't know if this is a Sony or an Android thing but my Xperia Z is slow at charging even with the supplied sony charger and cable (or a kindle cable) and when I try to use a generic micro usb it's even slower (in fact it sometimes feels like the non sony cable is simply preventing battery run down and not really adding charge).

Has anyone else found similar or got a solution (i've moved to this phone from a succession of iPhones which always charged fast)

I'm not an expert on batteries but based on my experience with other phones I think lithium-Ion batteries take a while to charge and are also quick to drain for the first couple of day's. Same problem as Me it takes about 4 hours for my Xperia Z to fully charge but only takes 3 hours to drain (while watching movies) After a couple of charge cycles though it should work as normal. based on my experience

I find that it charges very slowly when connected to a computer but charges very quickly when connected to the mains regardless of whether I use the charger it came with or any other usb charger (charges quickly with a Samsung or BlackBerry charger).

The difference is that your computers usb puts out a lower amperage then a wall charger make it take longer to charge.

Quite a lot lower, as it turns out.

A standard USB port outputs a maximum of 500mA. The supplied charger, otoh, has a rated output of 1500mA.

Some of the after market wall chargers are 2100mA.

Also just an fyi some of the newer Macs usb output is higher at 1600mA so they will charge the ipads while syncing.

How slow is slow? My phone charges from about 30% to 100% in approx. 2 hours (give or take). Charging will take a whole lot longer if the phone is being used or if you have background apps or services running, preventing the phone from entering standby mode (ie. WiFi hotspot, navigation software keeping the GPS receiver on, etc.)

That's not bad. My bionic takes at least 3 hours for 70%. But my battery is probable different size.

Update: your battery is actually larger then mine so I think 2 hours is pretty good. Since your wall charger is most likely a 1 amp charger and the USB is .5 it should take about twice as long to charge from the PC than the wall charger. If you have a 2.1 amp Charger than the PC should be about 4 times longer.

My phones's an Xperia Z using the OEM charger it came with. Though, I also bought another 3rd party charger which I leave in the office. The latter one can do 2.1A (originally meant for the iPad). I honestly can't tell the difference between the two chargers as far as charging time is concerned. To a certain extent, I think the phone also regulates how much current the batteries should be getting.

Devices will regulate what the battery gets, some will allow more through then others.

Default Big battery, big charge.

USB puts out a very small voltage only. So it could take a lot longer for the battery to final adopt and charge quickly. My experience: at first, the battery is actually DRAINING rather than charging, but after 5 minutes, it starts charging up, and 10 mins later, it is charging up quite quickly. About 3/4 the rate of wall chargers. Just wait a bit longer. BTW, my USB port is rated 500mA. So pretty slow. I want to ask if it will be faster if I charget it on the 1A port in stead of the 500mA. It seems quite the same...

You'd need a 1A output and its modified data pins (like your wall charger has it )...
Wikipedia: Jumpered data pins on USB chargers
