this is really strange...a have R2b too...but no boost!! I just turned the phone off and on again..result:
Before:
Stand by --> 258h
Talk time --> 5h 26m
After:
Stand by --> 133h
Talk time --> 3h 17m
I think this is not normal!!
I experience such a huge difference when I don't use the phone for 10 hours approx. (over night)
Please try right now and post what your differences are...thanks to everybody.

My Nokia 8210 was the oposit it turned it self off and
if I turned it on it could show 3/4 battery power but if
I talked it would die pretty quick. (could send alot of sms'es though)
I think perhaps its not easy to write software that makes an
very accurate power estimation.
I sure wish there will be an brakethrough in batterys soon for cellphones and PDA's I guess the nokia and
p800 with build in camera and stuff will have very short use time before you have to recharge. unless the p800 uses the greater thickness mainly for larger battery. oh well

I used to experience this with my T68m, but after upgrading to R2B, it does not lose but gain power when I turn it off and on again! Dunno why the opposite happens to others!!
same thing here--after upgrading to r2b, i get MORE time after turning the phone off and back on, whereas before (r1b), i used to get either no change, or a reduction in time.

just tried it a few times in a row (i have r2b software). results:
before:
stand by: 46 h
talk time: 0h48
(i'm in the middle of my 5th day of use since my last recharge, turning the phone off every night for an average of 7-8 h/night...)
[turn off]
immediately after turning back on:
stand by: 48 h
talk time: 0h48
2-3 minutes later:
stand by: 51 h
talk time: 0h48
[turn off again]
immediately after turning back on:
stand by: 47 h
talk time: 0h48
2-3 minutes later:
stand by: 53 h
talk time: 0h48
[turn off again]
immediately after turning back on:
stand by: 53 h
talk time: 0h48
2-3 minutes later:
stand by: 52 h
talk time: 0h47
[turn off again]
immediately after turning back on:
stand by: 46 h
talk time: 0h47
2-3 minutes later:
stand by: 52 h
talk time: 0h47
anyhow, i think it might depend how soon you check it after you turn it back on. for me anyways, it seems like it usually needs a couple of minutes to "equilibrate" (upwards) after it starts displaying remaining time when you turn it back on... i usually get between 5-8 days with the battery between charges, with an average amount of talking/sms's/wap/bluetooth/IR... i really can't complain!!!

Phone start up really takes up lots of power. To make ur batt life longer try draining ur batt til it turns off then charge while ur unit is off till full, ul get a gud charge after that process

OK! Fist the test ... after more than 12 hours (night) standby, only alarm was used:
stand by: 233h, talk: 8,33h
First time restart:
Directly after asking for PIN codes: battery monitor boosts up! (no GSM field found(!!!))
When start up completes: battery monitor drops down to the previous stage: now 239h, 8,33h!
After writing all this here, turn off & on again ...
Now only 222h, 8,33h before(!) turn off and ...
As always(!) directly after asking for PIN codes: battery monitor boosts up! (so now no GSM field). When the start up completes and both GSM & GPRS fields found (!) it is still here (at more power) and only after some seconds from start up complete (battery hours monitor software started ??!!) it drops again to:
207h, 8,33h (!)
and ... after one minute of stand by it is: 238h, 8,32h(!)
SO... a talk time is always about 8,33h, but stand by ranges between 207 & 239h ... SO NOTHING STRANGE HERE!!! As you know stand by time ALWAYS changes (IN ALL PHONES) because GSM/GPRS field's parameters are ALWAYS changing ... e.g. GSM-cell changes (even if you are not moving!!!) etc.
It is VERY DIFFICULT to write battery monitor software that monitors STAND BY & TALK times! For this reasons Nokia is not including this functions to their phones (stand by times will be changing always!), but Ericsson actually have BEST battery monitor software (according to other brands) that works very good (not 100% fine but very very good). So if your GSM field parameters chaneges (they are always changes A LOT after restart according to state before turn off because GSM-field searhing uses A LOT OF POWER and it almost never finds THE BEST (power saving) field firstly!) don't think it's ericsson error. It is your operator error that has NOT SO GOOD GSM-field coverage in this place (I also lost a lot of power after restart IN OTHER places like this where I'm now or when moving(!!!) at the same time!)
And never trust for all 100% to battery monitor (it is very hard to write 100% working battery monitor!) - it is good on ericsson phones, but not 100% good!
I always mentioned this bug (with old & new R2B soft) but I always was thinking it is battery monitor bug NOT BATTERY ITSELF!!!

If you really lose 50 hrs every time you do that then after 4 or 5 times the battery should be completely flat. I tried it and it wasnt...
Actually, I think that the "drop" is more down to the way the phone calculates battery power.
Have you noticed that, when fully charged, the phone shows 50-100% full for about 1.5 days, but then the final 50% disappears in no time at all (like half a day)?
Switching it off then on again seems to give a more realistic view of the battery status.
I think that the phone calculates remaining battery life based on the actual battery status on power-up, but bases the calculation on usage while the phone is on...
Try this : if you have less that full charge, note the remaining time (my case - 185hrs), switch off the phone, then on again. Now check it again - mine says 162 Hrs. Leave the phone alone for 10 mins, then check again. Mine now says 153 Hrs. 10 minutes later and mine reads 162 Hrs again. Weird, eh? (s/w R2A)

..it's really a strange thing...
After my first try:
Before:
Stand by --> 258h
Talk time --> 5h 26m
After:
Stand by --> 133h
Talk time --> 3h 17m
I turned the phone off and one again for about 3 times.
Now it looks like this:
Stand by --> 98h
Talk time --> 2h 13m
even after 10 minutes...
I understand that it isn't easy to build a good Battery status monitoring software....but this is even bad!
Agree?
