To Bostein:
Yes, my GSM-operator (EMT) as fine coverage here in Estonia. You can see it here: http://www.gsmworld.com/cgi/i[....]pl5?cou=ee&net=em&frame=middle
I'm sure this is one reason for long battery life.
About sms-ing and battery draining - it would be really interesting to know what are people think. (Not only owners of T68i)
PS. Bostein, please treat your ageing T68i with care and love

In the last few days i had to recharge my t68i almost twice a day. I've been surfing whole morning,5-7 hours approx and i had to recharge my batt every day when i came from school. But when i'm not using gprs so much i manage to get two days of battery life. Anyone else had to recharge batt every day?

@Aivar
What ur friend says is right, sms-ing does drain the battery. there are a few reasons for this
1. The backlight is always on when typing, so the battery drain is more. Yle u make r recieve calls, the backlight is on only for say 10 seconds or for how much long u had set it to be switched on.
2. If u have key sounds then that also takes some power to emit the sound, though this is negligible, this does drain the battery.
So ur friend is absolutely right bout sms-ing.
I use bluetooth always on and i send somewhere around 150 smses per day and the talk time is around half to one hour. the battery lasts till the night. I mean when i do a full charge early in the morning say around 7, it lasts me till 11 in the evening, the led doesnt flash red, but its dangerously low.
Thats my T68 and about my P900 its a different story altogether, i always use it as a gprs modem, and i charge it most of the time on the sync station itself. so will have to test it one day.

When i use my t68, not very often, i have to charge it every day. As written in the post before, the screen drains battery standby time in the first line.

I'm proud to wake up this old thread again. Today, on 31 May, three years ago I got my brand new T68i. I'm glad that it has served me well and it looks almost like new. During recent months the yes-key started to misbehave a bit, sometimes it needed to be pushed twice or three times to react. But now it works fine again.
Especially I'm happy about the phone's superb ability to use the battery very economically. Even after 3 years the average standby time is 8,5 days (over 200 hours). Recently, some weeks ago, the battery power lasted for a 10 days (240 hours).
And as I have said before, the standby record of my T68i is more than 11,5 days (over 278 hours).
During these 3 years I have almost always let the battery drain completly empty, before I have started to charge it. Only some few times I connected it to the charger when the phone was on. But even then the phone showed 0 minutes for a standby and talk-time.
Yes, I'm not a heavy user. Usually I have 15-30 minutes for talking, 0-5 minutes for gprs and 0-2 sms's during after charged period. But I carry my phone with me almost everywhere, it does not stay in one place only. By the way, once I talked nearly an hour and the phone still lasted ca 200 hours!
As I see no new good looking Sony Ericsson phone in the market nowadays, I hope that my T68i will continue serving me well. How many years, I don't know. Perhaps, if Sony Ericsson will make another good looking small phone with mighty battery and it handles
GSM 850/900/1800/1900 + WCDMA, I may consider to buy it. But how can I be able to leave my beloved T68i... It gonna be a hard heartbreaking choice...
Here is picture of my T68i, photographed today.

This is just a little note to say that my T68i (with original battery) is exactly 4 years old now. But the battery is still mighty and works like a new. The average standby time is still 8,5 days like it has been during those years.
Superb cooperation between the phone and the battery
I know that lithium polymer/ion batteries should not have so called memory effect - but before I start charging my phone's battery I nearly always let it run so empty that the phone switches off. Seems that my battery likes to be used in this way
Perhaps I have a chance to wake up this post also after another year, on 31 May 2007
Posted by BobaFett
How do u manage 8.5 days standby? Not many calls and very good rec i think.
Posted by Aivar
BobaFett, you are right.
During those 8,5 days I usually make/receive calls for 15-30 minutes, sometimes I also use GPRS for a few minutes and send one or two sms. But a couple of times I have experienced also the situation, when I make/receive calls for 45-60 minutes and the standby time is still more than 8 days!
And yes, the reception is usually very good here in Estonia (it's almost impossible to find "no network" area). When I am abroad, the standby time drops to 5-6 days.
But I remember my T18i - despite the fact that I talked not much, the power of battery turned bad after 1,5-2 years. It would be really interesting to know, when the battery of my T68i "gets old".
Posted by BobaFett
aslong the "gel" in the battery is ok, might be some more yeras long...
Posted by *Jojo*
@aivar - That's really a remarkable performance for a battery
Usually it will only take 2 years (3 at the most) for original batts to last (lifespan). Just want to ask you how do you charge the battery on your T68i dude?, do you full drain it first before charging or do you charge it as you please 
I just acquired a T68i and have both the white and black (rubberized) original batts . . . I hope this will last for years too 
Posted by Aivar
To JN,
As I said I like the good old method
So, before I start charging my phone's battery I nearly always let it run so empty that the phone switches off. Only seldom I have needed to start charging it a bit sooner - but in that case the remaining standby time has been only from zero to some hours and once ca 50 hours.
Posted by BobaFett
Do u never discharged the batt? Lets say every 2nd month
Posted by Aivar
What do you mean by discharging?
As I understand this must mean that the battery should be used until it has so little energy that the phone switches off.
As I said, I do it nearly always. Let say, in 96-98% of cases
Posted by BobaFett
I ment to fully drain the batt
Posted by Aivar
How? I really don't know.
Posted by *Jojo*
@aivar - Yeah as I am seeing reports back then that it's good for the fone to go totally drained prior to charging, but some says it's BAD for the handset . . . in my case (T68i) . . . when I see the battery in yellow color status I am about to charge it, will not wait for it to go RED. I will try this 8.5 days (stand-by time) with less calls and SMS . . . I am quite curious if the fone will really last this long
Posted by BobaFett
Indeed, lets say every second month, but imo at aivars case its not a good solution, cos he used another way, no need to change it
Posted by Aivar
But BobaFett,
I'm still curious, what you mean by "fully drain the battery". How is it possible to do?
I know that many years ago mobile phones had such a feature - when capacity of battery dropped very low the phone automatically started to discharge it.
Posted by BobaFett
U wait so long til the fone turns off by itself

I guess you missed some parts of my posts. But I can quote myself:
"Before I start charging my phone's battery I nearly always let it run so empty that the phone switches off. Let say, in 96-98% of cases."

Oh, my mistake, thought wait til tthe last warning signal.

After you have done some "totally drained battery before charging" cycles, please tell us, how long standby time your T68i could achieve before it switched off. How much did you use your phone during this time? How many calls, sms, gprs? Did you play any games, did you use calendar, record some voice memos etc?
Posted by DeLa
I can't resist to mention (OT) the A2628s I had; with the 1400mah battery inside the phone could reach *two weeks* on standby. It was almost rediculous how long this beast went. Never seen anything like it.
Posted by BobaFett
weird, why t68 didnt deserved a more powerful batt, compared to bus11 600 mah batt for t28 etc, 700 was a bit weak, for a colour screen fone...

yeh i have one of them i just broke the battery though - little wire snapped off the unit, haven't bothered to try and fix yet though....but yes, i left the battery in the phone for over 2-3years (switched off ofcourse
- and the battery was basically almost fully charged still.

t39 with bhc high cap batt is the winner. 3 weeks standby
Posted by *Jojo*
I will TRY to see if my
T68i will really last for a week or so 
. . . I won't be using any calls . . . just pure SMS (about 3 a day) . . . but I really doubt if the batt will LAST that long 4 days at the most I guess . . .
Posted by BobaFett
no, thaths the max. one of the member here ( sorry, forgot the name ) managed 8 days standby with the minimal usage.
Posted by Aivar
@JN,
I have heard that using (writing) SMS drains a battery even more than (not very long) calls. Maybe it's true, because when you are writing SMS, the screen of a mobile phone needs power for back-lighting. If you write long SMS, lots of SMS's or just think "too much" while writing, the active screen wastes the power of battery. But when you are calling, the back-light goes off after few seconds.
I have also experienced that after I have sent lots of SMS's, the battery doesn't last so long than usually. (By lots of I mean ca 10 SMS.)
I suggest you to try to achieve the maximum standby time of your phone (battery) in this way: use your phone mainly for calls (ca 15-30 minutes)and only for 1 or 2 sms, perhaps also some minutes for GPRS. Sure, you also must have a good GSM-coverage.
But of course, if you will receive lots of important calls, you can't make this experiment
Posted by BobaFett
thats with the sms writing is true. according my experiences, u can browse ca 2 times more on the net, then as making calls.

@aivan - Yeah makes sense about the SMS dude . . . unfortunately, I don't call that much . .. as there's NO one to call to . . . maybe we can chat here some day pal
SMS is OK, as I do this most of the time when I want to know the items on sale (website) . . . and GPRS, YES, here at Esato . . .
Posted by Aivar
Just a fresh note: yesterday my T68i switched off after 222 hours of standby time. It is 9 days and 6 hours. During that time I had calls for 25 minutes, gprs for 6 minutes and 1 sms.
But as I have said before, this is not its "personal best" - the record time is 278 hours [11 days and 14 hours]
Posted by BobaFett
this is the official standby:
Talk: 7.50 hours (450 minutes)
Standby: 384 hours (16 days )

@boba - Are you sure that the fone is turned-ON here
This is REALLY INCREDIBLE if done for the record ! My max is still at 4 days . . . a 5 minute call and only some SMS . . .

It is really hard to believe it. I have experienced such a short standby time only for a few times. Then I used gprs for 1-2 hours, had calls for 30-50 minutes, sent many sms, played some games etc. Also I get only 4-6 days standby time, when I am abroad (using roaming).
Do you live in well gsm-covered area? Do you have to use roaming a lot? Where do you hold your phone? My phone usually stands in a nice mobile cup
Posted by BobaFett
thats really amazing
do u flash your fone with the last fw twice a year? that helps the battery.

@aivar - Well I always 'hold' it in my left ear with my left hand - simultaneously ! I guess Boba is quite right with his past post . . . re: the battery that I just bought - black/bst-14 . . . the battery was stucked in the shop for 3 years, until I manage to buy it! That was my query then, if buying a 'stocked' for long battery has any effect with it's performance . . . after? Looks like it does
!
Posted by BobaFett
@jn actually, if the batt was stocked yeras long, but never used and boxed ( especially li ion and li pol ones - should work fine. its just very important, that the batt shouldnt be charged not even for a second.
Posted by Aivar
@JN
I mean, where do you hold (keep) your phone when you are not using it? Is it in the table or deep in your pocket etc? Do you have mainly good GSM-signal?
@BobaFett
No, I don't rewrite the software. I have the latest one R8A when it came out.
