I have used the device for about a week now.

I have two computers that I syncronise my device to - laptop and work komputer.

I also use app caled PPCPimBackup to back up call logs and also contacts and calendar.

Now I installed a new ROM on my device, then restrored all contacts and calendar enrties etc. with thw PPCP tool.

Next time I connected my laptop and X1 the Active sync "syncronised" the contacts and calendar and the outcome was that it copied all the contacts that were in laptop to device and vice-versa so I have now double entries from everithing in both devices.

It seems that the ActiveSync doesn't check the entry name or contents but some unique idntificatsion that it autoatically generates for every entry on the first sync attempt.

What should I do next time I Hard Reset my device so that the sync. still recognises the last syncronised setings?
[XPERIA X1 General] laurence0609:
I don't think it can still recognize your last synch after a new hard reset. What you can do is to change the sync settings on your PC. Hope this somewhat helps.
[XPERIA X1 General] Moger:
Yeah thats the problem. I dont find any useful seting to change. Any specific suggestions?

The only thing I came up to is to delete all contacts and calendar inputs from one device (computer).

How can i flash another new ROM (WM 6.5 for example)?

thanks a lot!

Perhaps it's your X1 itself? I myself and a couple of friends have X1i's and X1a's and we do not have such a problem.
[XPERIA X1 General] Webbmeister:
not necessarily a design fault

saying that its a design fault that your battery warms up is a bit of a sweeping statement. WiFi is notoriously power hungry and just because that device warms up a bit doesn't necessarily mean its going to get worse and worse and explode. if you work on that principle then may be none of us should use wireless routers as they often get pretty warm too - I know mine does!

Also, even if some devices manage to give the impression of being cool, it doesn't necessarily mean they are. they might just have double walling around the batt area, etc.

If you are worried though, go ahead and sell your phone - its only you that looses out!
[XPERIA X1 General] Ruudfood:
I've also noticed that it gets remarkably hot when charging but that's when charging from the USB port on my laptop. Haven't really considered how hot it gets when charging from the mains or in my car. Will test it out on a long journey in my car and get back to you.
[XPERIA X1 General] Dragonet:
My X1 works very well and has no battary problem. The durability of the battery is excellent!
[XPERIA X1 General] imrellik:
If you say excellent, whats been your experience? I have to recharge my phone every second night, at the very least.
[XPERIA X1 General] Lulis:
No problems here

Can't say I've had any issue with hot batteries on my black X1, my mate who has a silver X1 often mentions that his battery gets very hot.
[XPERIA X1 General] ianl8888:
This is exactly the type of issue that arouses the partisans ...

but the only sensible reply so far was Ruudford, who states he will test his X1 on a long car trip.

That's sensible - I've tried on an 10 hour field mapping trip and in the end had to use the Polaris to maintain mapping data integrity

The exact question is: "What happens when you use wifi or GPS for an extended time (>1 hour at least) while the device is on charge ?"

I've given my results - from three (3) new batteries. These results show that the device is underpowered.

No other answer apart from Ruudford so far has actually addressed this exact issue I've pointed out.
[XPERIA X1 General] anaadoul:
Yes, i completely agree that the phone becomes a bit HOT when using WiFi/GPS while on charger, and really this scared me for a while.

it even get's hotter when using WiFi/GPS and charging through USB Port of a PC!

this is surly serious issue, regardless of the heat that might explode the battery (i think it's still far from that level) but this really might cause some problems internally!

we all know that using hTourch on high beam has melted the LED Base of some devices and dammaged the vibrator (not pointing to hTourch or something, with respect to the great application and the author) but heat is a really scary issue that Might (and i say MIGHT) dammage the X1 on the long run.

how to solve this?

i have no clue, maybe some electonics engineers here will give some explaination of what's going on. after all, i'm just a software developer after all :S

i agree that this must be addressed and attended by SE (replacing batteries/chargers/anything else) or "could it be a software problem?" like the software is utilizing the CPU much to decrypt the WiFi signal? or maybe wasting the CPU cycles?

possible! but not as a hardware hunger for power.

btw,

have you tried to upgrade to R2A version of the ROM?

after all i noticed that in the R2A my battery lasts longer, mybe fixed some high current consumption bugs! the heat is still there but i think (not sure) it's less that before.
[XPERIA X1 General] Nocturnal310:
if i dont open the keyboard..it relly gets hot on wifi...so much so that i can smell the heat
[XPERIA X1 General] comeradealexi:
so what would the ideal battery specs be?

my phone used to get hot but since the rom update i havent noticed it at all.
[XPERIA X1 General] foxcheng:
when your reception is low, your phone get hot easily when surfing internet.. More battery consumption for grab the line.
[XPERIA X1 General] mkouk:
I have also noted my X1i overheat whilst charging and the GPS/WiFi is on use but considering the power usage by those two functions I assume it is the norm, especially with the X1i having a metal casing which allows the heat to flow more freely from the inside to the outside casing.

Coming back to the first post on here...if you wanted only people who have the same opinion with you to reply you could have at least made it a plain and clear. So dismissing replies that you simply don't like as non constructive is very silly.

If you ask other users about their experience in similar situations, the replies you are going to receive are bound to be different because the variables that come in to play are countless.
[XPERIA X1 General] tiggerzn:
ianl8888, my phone has the same problem, now that you have pointed it out! Once or twice when plugged into the wall or charging via USB, I have mistakenly left the WiFi on. The back of the phone gets extremely hot. I haven't used GPS yet.
[XPERIA X1 General] Cano3247:
I have the same problem, about 2 weeks i just travel to the beach and near to 1:30 hr of trip, my mobile stop to work, I do soft reset, and I catch that was really hot, because I'm charging and using GPS at the same time, my mobile is X1a and I have R2A ROM version. I imagine can be touchflow, so I uninstall and leave phone like originally came, but when I return from the beach I have exactly the same problem, I can't do a trip of 2 hours using GPS. I hope some one can find a solution.
[XPERIA X1 General] comeradealexi:
so what exactly needs to be done - software problem or battery problem????
[XPERIA X1 General] Sfkn2:
Has it ever occurred to anyone that it may be the cooling system in the phone and that it isn't ventilated right? Let's open a few holes in the case and see what happens! :)
[XPERIA X1 General] anaadoul:
afaik, no phone have ventelation nor cooling system!

Edit : Heat-sink? Maybe but i don't think so! these things are not supposed to generate much heat! too much heat = more wasted energy = lower battery life
[XPERIA X1 General] vanilla.coffee:
Coming from a Nokia 95 that I used to have to charge every 2 days after using it for GPS and WiFi I am totally impressed with my X1i that lasts 4 to 5 days with similar useage.

I remember my first phone (A motorola tac in 1995) that had a battery lasting all of 6 hours... :)
[XPERIA X1 General] michaelthemage:
Well, great times you got. My phone is empty with 3 hours of GPS on.

As to the heating of battery/phone, my phone gets quite HOT outside when I use anything for a period of time (1hour) while NOT on charge.

I am using media player a lot to listen to music and after half an hour the phone becomes hard to hold in the hand because it heats up outside/backside really strong. Again, while NOT on charge, just using the battery power. And frankly that is more of concern that when on outlet power.

I had this with 2 different X1i's and both Silver!
[XPERIA X1 General] superweijie:
This phone can get hot at times. WiFi is sure.
[XPERIA X1 General] anaadoul:
This i guess is not a faulty unit if you have it in 2 devices!

are you using a custom ROM? what is your current ROM and what is it's base?

today i tried driving and navigating while playing Music through Stereo BT for around 30-45 minutes. the phone got only a bit Warm. it didn't heat up at all!

i recently upgraded to the R2AA10 through SEUS, got GENERIC_UK with some tweaks in the registry (which are not related to this issue).

can you all please post your ROM version so we can have a comparison?

Cheers ;)
[XPERIA X1 General] fards:
gosh talk about using emotive language

"overheat" "explode" etc.

bearing in mind the amount of complete noobies on here I think we'd have at least one explosion already if it was going to happen.

My x1 gets warm, but not hot. Ie it's noticeable. having had several other PPC before that also felt warm with out the battery cover on then I don't think it's a real issue.

My laptop feels like it has been getting considerably warmer than my x1, and the power brick for that gets exceptionally hot (as in too hot to pick up comfortably). Yet both operate fine (and within operating temperatures internally) for over 3 years.

As to power use, I went out yesterday and spent 8 hours cycling using TF3d music player and memory map consistently throughout that time, with some email and browsing during lunch over 3g. my battery was a 30% by the time I got back.

I don't think gps takes up much power it's the 3d gps apps that people use that draw the power.

Wifi does eat power (and as posted above my router gets very very warm when used, but not as much as my old linksys), but that's not anything new with the X1.
[XPERIA X1 General] artesea:
Have seen X1s get hot with Wifi and a Charge (mates), others not so bad (mine).

My only suggestion is not to keep it on charge for so long. The battery will do a good few hours of GPS or Wifi, just ensure the phone is fully charged at the start and give it 20-30 minute boosts on charge. Should last most of the day.
[XPERIA X1 General] nik40:
Has more to do with aluminum battery cover than anything else. This magical property is called thermal conductivity:

http://en.wikipedia.org/wiki/Thermal_conductivity

compare values of epoxy (normal cases) and aluminum (X1)

I do not think X1 battery itself is any warmer than that in the average phone. On the contrary, it provides with better heat exchange and minimizes internal overheating: it may well be cooler than in the average phone!
[XPERIA X1 General] comeradealexi:
makes sense - your more likely to notice the heat because the cover is conducting the heat so well if it was something else u might not
[XPERIA X1 General] ianl8888:
Well, my language was the reverse of emotional, I'm afraid. The hard truth is that the battery (three new ones so far) so overheats when using either wifi or GPS while on charge >1 hour that it is too hot to touch with any degree of comfort ... literally true. Not just "warm" - but very, very hot. I tested this again yesterday while driving with my wife for about 90 minutes to a cinema complex, and she wouldn't touch the device at the end as it was just "too hot" (her comment). Obviously, I haven't allowed this to proceed unchecked. The device becomes unstable and erratic, loses sound, and the battery continues to heat.

So far, those posts that actually refer to "heating while on charge using wifi or GPS" (about 30% of the replies to date) acknowledge that there is a real problem. Most of the other replies simply castigate me without actually answering the question - I've seen this cycle in various sub-forums here quite a few times ... to be expected, I suppose.

For those asking about the ROM, I'm using JL's Lite v2.1, based on the NAM R2 AA008 release. The overheating also occurred on the stock UK R1 ROM that the device had out of the box.

Since those 30% of posts that actually addressed the question also concur that there is a real problem, I'm convinced now that I'm correct - the battery is underpowered for the device, and hence is unfit for purpose.

BTW, I don't think that the SE engineers stuffed up, I think much more likely was a manufacturing costs decision from non-engineers based on anticipated "market demographics" - think about the marketing cynicism implied in that.

Solutions ? Please see my 1st post. SE will never admit to this problem. Previous devices I've owned and used never had this issue - HW6515, HW6910, Eten X500, HTC P36001, HTC P3650 (still in use)

Why would I not choose another HTC device when the P3650 (Polaris) has proved so reliable and useful - apart from being only QVGA ? Because recent releases from HTC have deliberately excluded the UMTS 850Mhz frequency to avoid the Qualcomm-Broadcomm royalties issue.

All of this is a real pity ... xda-devs is a wonderful forum for manipulating these devices to do what we want.
[XPERIA X1 General] anaadoul:
that mekes sense, but why does the Keyboard heat up also?

why more while on charger, and why more on charger and WiFi? while one alone will not.

honestly, i have been playing with my device alot today! and it was really normal, a bit warm. i was surprized not feeling hot as it used to be!

maybe it's something i have installed earlier? or could it be the new ROM?

today i talked to 2 friends who got X1, Silver (mine is black) and both R1A, one of them reported that one time he forgot WiFi ON all night while the mobile is on charger, the phone was HOT that he could hold it but it was abnormally HOT, he will make a hard reset and test. let's see how things go on the R1A, then flash with R2A and test again ;)

i insist that there is something behind this, it's not a normal thing to heat like that.

btw, i noticed onething, when the device is hot, it's losing much more battery that when it's not (on R1A, it used to get warm with WiFi and no charger in my case), but when i'm outside and it's cold the battery would last longer! this might be some batteries physics
[XPERIA X1 General] ianl8888:
I was after actual answers to the actual question - overheating while using wifi or GPS >1 hour while on charge. I was simply tring to limit an avalanche of partisan comments which do not address the question. Such replies are silly, not my post, OK ?

Question: "What happens when the device is on wifi or GPS > 1 hour while on charge, either wall outlet or car charger ?"

Not: "What happens if you turn wifi or GPS on for 10-15 minutes ?"

HP HW6515, HP HW6910, Eten X500, HTC P3600i, HTC P3650

All of these have never had this issue (guaranteed, since I've owned and used all of them). These are the norm, not the underpowered X1.
[XPERIA X1 General] ianl8888:
Yes ... but that simply admits tacitly that the problem is real, and the battery/charge system is indeed unfit for purpose.

And it doesn't address the issue of using the GPS for 8-10 hour field mapping projects.
[XPERIA X1 General] Trudi:
I've been using the GPS for a whole day while charging, never noticed anything special.

Yes this device gets warm after a small of usage with or without charging, but never hot. My Palm TX was even more warm than my X1 does in the same conditions, never had any problem for about 3 years...

Edit : why do you claim the battery is mis-designed ? Charging every 2 days is totally normal for a smartphone. Several collegues have other Windows Mobile devices, they charge more often than me, and I use it more often than them. It's even worse with a iPhone, you have to charge it every day if you use it as I use my X1.
[XPERIA X1 General] tjex:
I've used the phone plugged into the car while running TomTom on several occasions for over 1 hour (trips as long as 4 hrs). Can't say it gets way too hot, I can still hold it without any problems. My laptops gets hotter when used.

Maybe you should take some temperature readings with a thermometer as saying hot or super hot is hard to compare.
[XPERIA X1 General] geejun2:
mine does get warm as well. left my x1 on for 1.5 hours on GPS and it was between hot and warm. the battery was down 30-40%. i do hope something comes out to take over this. I am charging my x1 every 2 nites as well

Battery data

Hey,

Me (i own an X1) and a friend (owns a HTC Touch Pro) just finished making some tests with PowerGuard 1.24 and we came up with the following results that are presented in the attached graphs and zip file (contains an all the Excel Data).

We tried being thorough while making the battery tests but if you have any suggestions or comments on the data we came up with, don't hesitate to write : vlad.lapadatescu (remove this-for blocking spam) @gmail.com

We tried deducing how much power the phone consumed in

Flight mode (w/ or w/o Screen on Min/Med/Max) -> This was our reference

2G idle (substracted the reference)

2G call (substracted the reference)

and so on...

It would be really cool if other people would come up with results like this.

Just download PowerGuard 1.24 and start the poll interval with 15 seconds. :D
[XPERIA X1 General] Fulgore69:
I agree with the first post, yes it get hot and indeed it the fault of li-polymer batteries typical of them.....Not such think happen on lithium-ion normal battery...
[XPERIA X1 General] ianl8888:
Yes, I'd hoped that too: Li-poly vs Li-ion, but no such luck.

Unhappily, both types drastically overheat when on wifi or GPS while charging for >1hr or so (I've tried). Prescribed batteries are 3.7V and 1500mAH.

Perhaps a Mugen battery (not even produced yet) at 3.7V and 1800mAH or so will alleviate the problem.

I can't live with this problem - it makes the device almost useless to me, just an expensive toy cynically marketed (hence my phrase "unfit for purpose"). Either a more powerful battery that can charge whilst feeding wifi or GPS without overheating, or an Acer DX900/X960/F900 - whichever comes first.
[XPERIA X1 General] artesea:
@ianl8888 have you tried a different X1? You keep going on about changing the batteries, but like I've said I've seen the issue on some handsets (to the point where it felt like you were going to burn your skin) whilst others only get mildly warm.
[XPERIA X1 General] ClarkKent111578:
Solution

ianl8888

I agree there is a bit of a flaw in the battery/design of the X1, but there is no use dwelling on the negitives continuously because clearly it has'nt gotten us anywhere.

I for example use GPS day in day out and my solution was:

I designed a holder for my X1 that is positioned just infront of my aircondition for my car (thus cooling the back of the X1 wher is usually gets hot) and with that in operation as well as the car charger I can use GPS for as long as I need...NO PROBLEMS!!!!
[XPERIA X1 General] anaadoul:
nice idea, but what if it was cold outside and you have heating on?
[XPERIA X1 General] johnchan78:
Guys... when you say "feels kinda hot"... its very subjective.

Use Batti or any number of programs that can read the battery temperature and get an ACTUAL reading.

Mine, with Wifi ON and charging via computer USB, tends to hover around 46-48 degrees. How about you? Is your's much hotter?

Also useful would be to look at CPU load. I once found a program running using 50-80% of the CPU, and found the battery hotter... but I dont think it ever exceeded 50 degrees.
[XPERIA X1 General] ClarkKent111578:
Re Solution

anaadoul

I'm from South Africa and I can assure you that we hardly have cold days here (hav'nt been through Winter yet since I got my X1) and even when that day actually comes all I'll do is put the aircon a bit lower and direct the colder air away from myself and only to the X1....EASY AS THAT.
[XPERIA X1 General] ianl8888:
Thanks to those that added to this thread.

We did actually resolve something - about 80% of the replies that had actually tested the device on wifi or GPS while charging for longperiods reported heating above expectations.

Widespread enough to discard either faulty batteries or faulty handsets ...

For those who resolve to deal with this by the judicious use of air conditioning [:)], or simply don't see the need to use wifi or GPS on charge for long periods, good luck with the compromise

The choices I outlined in my 1st post are likely the best resolution for the uses I have. I can't afford such a compromise, my business requires a device that does what it is supposed to do.
[XPERIA X1 General] CapsLock1:
I have to agree with ianl8888's comments re battery heating up and battery life. If anything, mine is even worse. I'm flat out getting 12 hours out of a charge and I don't use wifi and gps as heavily as he suggests he does. I might use wifi and gps each 15-30 mins a day.

I'm wondering if perhaps if its not a bad (faulty?) batch of phones or batteries. Mine is stock standard X1a Australia.

Phone's details are:

Software Id: 1221-3064

Software Version: R1AA021

Customization Id: 1221-3134

Customization Version: R2A

Build Date: 08W49

Battery details are:

Model: BST-41

Voltage: 3.6v

1500mAh

Build Date: 08W39

Does this throw any light on the problem?

Cheers
[XPERIA X1 General] Sfkn2:
Some members here have reported that the R2A firmware yields a better battery life.

Can you report back after you update your firmware?
[XPERIA X1 General] kdspiv:
My Xperia gets pretty darn hot so I have taken note of the Temp.

These are according to Homescreen++

Normal Idle temp is 81F-84F

Charging - 91F

Talking on the phone or listening to MP3 with wired headphones - 91F to 93F

Listening to mp3 via AD2P - 92F to 95F

Watching a movie converted to 500kbps, 96khz, 25fps - 97F to 100F.

Watch a movie at anything else (any conversion that makes the processor hump it a bit) 101F to 102F

With normal WiFi my Xperia runs at 103F - 105F.

If I have a weak signal and I am downloading Youtube HD videos, the Temp will hit 110F very quickly. So if I am doing this for any length of time I pop the Battery cover.

I am thinking about buying a 2nd battery cover and installing some screen for venting purposes.
[XPERIA X1 General] XavierGr:
Why is heating a problem, I really don't get it. As long as the unit works as intended with no malfunction I can't understand your fuss about it.

Yes I can assure you too that my device gets pretty hot on intense usage and one reason for that is the battery cover which seems to conduct heat. But have you ever touched a router or laptop. XPERIA's temperature never gets that hot and saying that it might explode is an (extreme) exaggeration.
[XPERIA X1 General] artesea:
I've felt X1's get that hot* and it's a worry to keep on holding them, which unlike a router you tend not to keep in your hands / trouser pocket.

* must add that my own X1 has never got THAT hot, so I'm rather lucky
