are there other useful tips on how to improve battery life besides SE's suggestions (turn off 3G, GPS, don't use 3rd party apps, carry the charger all the time, etc)?

Sixth Issue: Is nice that Sony Ericsson has some suggestions to improve battery life but I don't think they are useful

""( The first two are no brainer

To decrease the brightness of the screen:

To turn off Bluetooth™:

Other useful tips to maximise battery performance:

    * Only use location services when needed.

(that's great if Issue number 3 is fixed)

    * Turn off push email and synchronise your mailboxes manually.

(Again  this wont drained as much battery as Timescape, lets face it, hardly  anyone use timescape and if you happen to use it, TS will drain your  battery quite fast unless you dont get updates often which defeats the  purpose of Timescape)

    * Minimise the use of third-party applications.

(Third party apps could outperform some SE apps but the again is good to double check the app before installing them)

    * Charge your phone often. The battery lasts longer if you charge it frequently.

(Its a hazle to must carry the charger at all times because battery life sucks)

     * If you are in an area with no coverage, your phone repeatedly scans  for available networks. This consumes power. If you can't move to an  area with better coverage, turn off your phone temporarily or use Flight  mode.

(another  no brainer that will drain more battery but again it defeats the  purpose of a mobile phone which is to stay connected specially if its  part of their campaing)

    * Turn off 3G, Bluetooth™ wireless technology and the Wi-Fi™ connection when you do not need these functions.

(I  understand Bluetooth and Wi-Fi, but turning 3G off? its a smarphone,  checking emails, MMS, watching videos, streaming music is all part of  the smarphone experience and again specially if is part of X10's  campaing)

     * Don't cover the phone antenna when you are engaged in a call or when  transferring data. The antenna is located at the back of phone

(It'll be helpful if we know the exact location of the antena, since the antena does not cover the whole back)

    * Browse the web with Wi-Fi™ rather than mobile data networks, and turn off Wi-Fi™ when not in use.

(this is true in a secure hotspot)

    * Close running applications when not in use.

(again a no brainer, even if is not for battery life reasons, if you keep 8 apps open the X10 gets really slow and glitchyhttp://www.sonyericsson.com/cws/support/phones/detailed/tipstomaximizebatteryperformance/xperiax10?c...)

We need a phone that has 3G, GPS, w/o having to carry the charger all the time, perhaps more apps from Sony Ericsson besides Creatouch

It's not the battery because I even borrowed a friend's X10 battery and it was the same issue, I do use task killer and I try to kill most of the apps often, after I'm done using them, So if there's an issue with american phones it will have to be with the Bands we use for 3G but then again I don't see how much more of an issue it'll be unless our 3G coverage is not as goos as European or the issue might be at a software level issue. Yeah the incall volume is quite bad, If i'm out doors there's no way I can't hear them, so I have 2 options 1) go indoors to finish the phonecall 2) use a handsfree device or 3) attempt to use speaker mode, but doing so the audio quality is quite bad and still not loud enough if you are in a freeway/car or around any noisy area. the ringer is not loud enough either and I think that can't be fixed because, I don't know if you notice while playing music/videos on the X10 if you hold the phone the wrong place (hahaha it just reminded me of apple saying people held the iphone 4 the wrong way) you will cover the speakers and well you wont be able to hear anything, I think that's one of the reasons we can't hear the ringer that and some other software issue. now the vibrate mode is just not strong enough, I don't know if you'd open your X10 or saw pictures of the X10 tear-down but the vibrating part is really small.

I'm glad we can work this out to help each other out and the blog community.

using the handfree set or a BT set will resolve your calling volume issue
