[XPERIA X10 Q&A, Help & Troubleshooting] Mayazcherquoi:
Received the external charger a couple of days ago and just received both 3200mAh batteries today.

I charged the original Sony Ericsson battery with the external charger, and it charged pretty well (although slow). However, a downside to this battery is that it ran very very hot during and after charge.

Nothing wrong with the charger, works wonders :)

Review:

The Charger:

The charger does exactly as advertised, and holds batteries of all sizes quite well (only tested on the stock 1500mAh battery and one 3200mAh extended battery). The LED is bright and very noticeable, and lights up the entire bottom portion of the device. It is pink when it still has quite a while to charge, purple when it hasn't got long to go (guessing >95%) and blue when completely charged. One downside with this charger though, is that it can quite easily come loose of the power socket if touched even with the slightest strength (this is both vertical to the wall, and parallel to the floor).

The Batteries Themselves:

I hope to have both these extended batteries charged by tonight so I can give a complete review tomorrow :) About 15 minutes into the charge of the first extended battery and it is still cool, unlike the stock Sony Ericsson one.

The Back case and Phone Thickness:

One downside though, is that they do double the thickness of the phone with the included back case. The back case attaches pretty well, however it isn't as easy removing it as the original Sony Ericsson one (this one is more firm, whereas the Sony Ericsson supplied one is more flimsy and flexible). I, however, do not see the back case breaking any time soon as it is rather solidly manufactured. The design is exactly the same as the stock one (a plain black), however the XPERIA text, Sony Ericsson text and Sony Ericsson symbol are both absent. The thickness of the back case does not interfere with neither the camera nor the flash.

Phone Usability:

Using the phone with the added thickness however, is a bit annoying and daunting at first. You have a smaller distance between the screen and your thumb, and thus forcing you to press harder on the screen and cause your thumb muscles to tire more quicker (and possibly strain with constant use). Also as a side-effect of pressing harder, touch is therefore less responsive. I am, however, in the early stages of using the phone so the outcome on the strain is just a guess. The phone with the extended battery is not suitable for those with smaller hands (it just fits reasonably in to mine, however my hands are quite larger compared to most).

(NOTE: This was with the phone placed where all fingers meet the palm. Holding it on the tips is a lot less stable and may be prone to being dropped if the handler is clumsy. However, it does increase the distance of the thumb and the screen).

(P.S: I can not comment on weight yet, however I will do so once I have at least one battery fully charged) :)

Battery Life/Stability/Temperature:

Battery Life is obviously much much better. The phone doesn't crash and it doesn't drain that quickly. The temperature is a lot more cooler than the stock Sony Ericsson one.

Couple of days after use:

For some reason, I'm not entirely sure why, the battery life seemed to of decreased (this was after running down to 40% then recharging to 100% a couple of times). I'm guessing, however, that this is because I am utilising the phone a lot more than previously. Now brightness is 100%, and I'm texting a lot more often now.

When I first got the battery and charged to 100%, it lasted 24 hours and was only on 99%. This, however, was when the brightness was at the lowest and mainly on deep sleep. Which is pretty good.
