What is the average battery life most people are getting from their devices? The reason for asking I beleive that my battery life has reduced drastically, I'm averaging 36hours. I do not use it as a phone, the Wifi & bluetooth is switch off, the unit is used for push email only and I receive about 20 emails per day, very little WEB browsing.
I'm sure my battery life was a lot better when I took delivery of the unit.

Mmmmm.. well I'd consider 36 hours fantastic but then it sounds as if I use mine a lot more for wifi, surfing, phone etc. than you. Perhaps an hour to hour and a half per day and charge once per day but will usually have 40/50% charge left I did see a post from someone saying with reasonably heavy use they could only get 8hrs.
Mike
i use mine mostly for data.. in a 3G area i average about an 9.2% loss per hour.. in a edge area i am averaging about 1.7% loss per hour... these are all estimates since the battery meter only goes by 10's
I am fairly certain that the 3G is eating power. I get a full days work out of it with a lot of phone calls, push email, BT always on, and occasional WiFi usage. I am almost always in 3G, I very rarely lose it and only when at a clients far away.
Later, Lew
BTW, A full days work for me is 9am to 3am.
3G is the problem. Consider switching to 3G via MortScript as described in another thread. Personally, I use the GPRS only setting for normal use. PushMail would consume a lot less energy with GPRS and the speed isn't such an issue for mails in my opinion. Whenever I'm willing to browse the net a bit more, I switch to 3G before doing so (takes ca. 15s via the script) and when done, I go back to the less battery eating and more reliable (for taking phone calls etc.) GSM only mode.
You will definately at least double the runtime of your Hermes. I can do 5 days (phone on at night, little use) by doing so.
Well I can confirm that 3G is the cause, as suggested I've switched to GSM and battery life is a lot better.
3rd charge i managed to get nearly 2 days, had a 4 hr gprs web session last night on minimum brightness and still had 30% battery this morning.
if the battery goes to 0% what happens? data loss or just turns off?

Other than any document/application open at time of shut down you should be ok, not like my old Clie that looses everything that's not screwed down on the storage card. In fact quite often I deliberately remove the battery for a while if I reckon it may help with a lock up (normally due to some rubbish downloaded freebie!!). All saved programmes to Device memory and card remain in tact.
Mike
Using my TYTN for email (check every 30 minutes), newsgroups (check every 30 minutes) and reading both every 2 hours.
Also using the phone for lots of browsing.
And i am also using my phone for making some phonecalls over the day (with and without bluetooth carkit), i get to use my phone for about 16 to 18 hours without need for a recharge.
[OT]
How do you enable auto email send and receive?
Cant find the option anywhere
[/OT]
if you add an email account to your tytn you get the option advanced at the end of the settings. if you click it you will get the option to send/receive at a standard timeperiod.
I use UMTS for email and web browsing continuosly for 2 hours and I'm down to 10% after a full night charge. It's pathetic.
Your device is broke, or your battery is defective. Seriously, if you have a warranty, act on it.

i dont know about that.. everyone seems to be getting around the same battery life... i would bet that if i used mine on umts continously for 2 hours i would be close to the same drain, UMTS sucks alot of battery

that's true and umts sucks a lot of power. i am using mine on umts in tokyo and i can only get 10 to 12 hours. i use it mostly for push email (about 80 emails), an hour of browsing and some phone calls a day. i've ended up purchasing mugen's 3000mah one to get through the day without recharging.

I highly doubt it as I have two 8525 and both of them will be at 10% with 2 hours of continuous use.
Well I'm on my 2nd battery.First one was replaced under warranty as I was getting about 8hrs with very little usage.
I'm on my third charge with the new battery. The first & second charges have given me about 15hrs.
Agent said I should be getting 4hrs talk time and if the second battery is also [email protected] then they will replace the phone. So I'm monitoring until next week.

This may not apply to you (as you probably know it already!), but Windows Mobile does not shut down programmes when you click the x in top right corner. To ensure you are not unknowingly running lots of applications in the background you need to use a programme that really shuts applications down properly - e.g. Magicbutton or HTC X Button. This can save considerably on both battery power and performance.
Mike
Mike, I'm using Magicbutton and make sure all apps are closed all the time. I've read a lot about the UTMS connection on all the time draining battery. I've just downloaded this app: http://www.gb-soft.cz/XDAII/product_gprs_tweak_wm5pe_en.htm
See if this works and extends battery.

Had a quick look at your link and yip, looks good going to try it as well.
Mike
I want to see how your X1's doing on performance. Please post your battery life with ur daily usage here please
For myself, i ran it only for a few days n i may have to get an extra battery to work...
phone fully charged by wall charger from 12am last night to 7am this morning (i know the crappy stuff about charging it thru PC, so i decided to go with wall charger).
unplugged at 7am
7am - 9am: phone was on without usage - wifi, bluetooth, everythings off
(battery bar from FULL to 80%)
9am - 11am: windows media player with connection for live radio online
(battery bar from 80% to 40%)
11am to 2:45pm: media player panel for mp3 usage, listening to mp3 nonstop with a few short phone calls
(battery bar empty and it shut off itself)
so i have total of 5 hours and 45 minutes of usage of the phone from 9am to 2:45pm, other than that it was just sitting turned on from 7am to 9am
Is it normal? please post urs here to do a little comparison!
Fully charged with the phone off overnight, 8 hours later without any usage (just checked the clock a few times) kept me at 100% battery level.
However, using the internet to browse through regular websites consistently and running Fring at the same time runs my battery from 100% to completely shut down in 3 hours and 45 minutes or so.
Today:
Fully charged and unplugged @ 10am
Surfed the web 30 minutes (opera 9.5)
Skype ~10 minutes (text messaging)
Checked mails (2 accounts) every 60 minutes = 10 times until 8pm
~20 minutes phone calls
all with HSDPA
battery level now 1:17 am, after 15 hours, 60%.
So, yes. Its normal and I think any other phone will behave the same with 2 hours listening to online radio + ~3 hours mp3 playback + few short phone calls.
Charged about 8h overhight, unplugged at 10am in the morning, bluetooth on all day, synchronized with bluetooth watch mbw-150 for all day, listening music over bluetooth stereo headset for about half hour, phone calls 35 minutes, turned on display many times over all day and in the evening at midnight, after 14 hours of usage I have more then 60% battery so not bad I think.
Battery life
Well my phone really is inconsistent. I keep forgetting to load it at night and i will be empty the next morning as long as bluetooth is on. No matter how full it was in the evening.
I do use it all day with bluetooth and about 1 hour phone calls a day over bluetooth + Outlook used a lot. It will be almost empty in the evening.
Bluetooth really is pulling the battery down.
ya, hmm maybe cause by network we are in... maybe some network require stronger use of battery to get reception... for this i cant really tell cause im not an expert...
by the way, im in US using ATT.
feel better now though by knowing its normal for a pda phone, actually its my first, used to play mp3 all day with sony's phone, lol
i know turning all programs and connection off will reduce use of battery, but is there ways to really make it run a little longer?
sidenote: my theme is Today, and i also make sure that nothing running in task manager...
Perhaps it has something to do with the radio ROM?
anyone? no hints?
Connected to EDGE, BT (syncing with car stereo only) and WLM 24/7 with about and hour or two worth of calls and viewing & answering sms/emails my battery lasts about 3 days.
Connected to EDGE, BT (syncing with car stereo only), WLM 24/7 with about 20 minutes worth of calls, viewing & answering sms/emails and listening to mp3's with the screen on with the backlight dimmed lasts from about 6-7 hours.
Connected to EDGE, BT (syncing with car stereo only), WLM 24/7 with about 20 minutes worth of calls, viewing & answering sms/emails and listening to mp3's with the screen off lasts from about 10-15 hours
charged th phone overnight swiched off, on at 8:00 MBW-150 and bt headset connected 2 hours of calls. no wifi or internet browsing, 3g and HSDPA off. and at the end of the day after normal use 23:00 battery was almost dry.....
100% in the morning @ 7:00 am charged all night using wall charger
HSDPA (or Edge depending on converage) all the time with Microsoft Push Email
10 to 20 SMSes per day
2 to 3 hours phone call
RSS feeds syncing every 1 hour using RSS HUB.
Bluetooth ON 24/7 in connectable mode, connected to BT headset (not sterio) and BT watch (MBW-150) using smartWatchM
10 to 15 Minutes of WiFi
i reach 10:00pm and the battery on 20 or 30%.
if i reduce phone calls (1 to 1.5 hours) i get 40 to 50% @ 10:00pm
this is a great battery life for me, i love it. the battery is affected by the current FW you are using and how many applications are running in the background (doing stuff not sleeping).
i use R2AA10.
Cheers
Alarm rings at 6:00.
Usage 6:00 - 16:00:
Two or three phone calls with a length of one minute or two.
Email checking for 3 accounts every 30minutes (HSDPA).
10 to 20 text-messages (receive and write).
Half an hour listening to music with headphones.
Usage 16:00 - 0:00:
Two or three phone calls with a length of one minute or two.
Email checking for 3 accounts every 30minutes (EDGE).
10 to 20 text-messages (receive and write).
Quarter an hour of W-Lan while searching the internet for updates to my programs.
Usage 0:00 - 6:00:
Standy with flightmode.
The battery drains each day for about 20%, so I charge the battery each 4th day (it should last one more day but you never know what's coming to drain your battery during the day )
I'm on YYYYY's german Manilla ROM
Hi,
New here, my first post.
Am using the latest update from SonyEricsson website.
No matter for how long I charge my phone never shows "Completely charged" status all the time its in "Charging" mode.
I have observed that it consumes more charge on using playing music, browsing, using Java tools, and if Bluetooth is kept on.
Take it off charge at 0700
3-4 hours internet use.
Podcast download and RSS feed checking + dl... (varies in a day depending on Podcast available or not and whats new)
Loads of sms
about an hour of phone calls
about 4 hours or so of reading/vocab practice (using Plecodict, a Chinese language tool)
after 2-3 days like this it needs charging again (40-20% depending on podcast dl)
Let it charge over night.
Lasts about 2 full days.
Make few calls, lots of texts, checks emails every 15 min and updates weather every 4hrs.
Also updates stocks, rss and other stuff.
Use facebook panel once a day.
After reading this thread i am a bit confused. I have My X1 for 10 days now, and it never held the whole day, which makes me want ma E90 back...
Couse the usage is just the same, maybe a little more WLM.
I have mails checking every 5 mins, no WIFI, or BT. AND 24/7 WLM connected, with 5 hours typing or more.
And i gues it is thy typing that consumes battery. Somehow X1 3" screen consumes twice the power of E90 4" screen? That just doesn't make sense. G2 or G3 doesn't realy matter. Well only little.
Will try for the first time tommorow without WLM.
Or Maybe WLM with me turning the screen of and relying on sound notification, instead of checking the screen all the time.
Still big downside for me, regarding the battery. Even E90 was at EDGE, couse, UMTS did not hold it whole day. God damm it we have battery tehnology from 100 years back...
can those with good battery life please post the rom and radio rom u are using?
thanks
Hi Guys! and Gals..
Wondering hows your battery life?? Can you make it through a day Ok? I have a touch pro on Sprint and battery life stinks in the worse way.
Last time I checked, it went 13hrs until 31%.
I usually use it for around 90minutes continously reading or web browsing during my commute. There is also 4-5hrs (or more daily) during which I only get 1-2bars of receptions, so it drains battery faster. There was probably also a 30-40minute phone call using bluetooth.
I can go an 10-12 hour day with light use:
45 mins of phone and text (no bluetooth)
20 mins phone (bluetooth)
30 mins misc.
30 mins games.
20 texts.
Data on about 8 hours without Wifi and 4 on (N enabled)
1 hour browsing, emails etc.
30 mins with Microsoft Reader.
Probably a little more.
Also syncing a lot with calendars.
Not bad, but I feel like it could be better.
t-mobile usa.
I have 75% by end of the day
Adjust your PEAK TIMES for ActiveSync, that way your device isn't consistently trying to allocate resources to collect data such as emails.
Screen brightness, system volume, hibernating times, etc.
ALL OF THOSE are key factors in how quickly your battery will be drained. Anything involving the on-screen display is what will quickly deplete available battery life on a single charge. That may seem very "cliche" to say, but the fact is, this device has a 4.3-inch screen, so it's a power hog.
For today, it's been 17.5hrs since I unplugged and the phone has been mostly sitting except for a few occasional brief checks of the phone, 30minute email syncs, and a 15 minute phone call. It's at 40% battery after the 17.5hrs.
It did drop around 20% in the first 6hrs since the phone was in an area of horrible 0-1 bar reception. The rest of the time has been 2-3 bar reception.
17.5 hours @ 40%... are you serious?
My TMOUS HD2 has never gone more than 8 hours on a full battery charge. This is with "normal" usage. Regular email checks, activesync with direct push.
Comming from the Blackberry Bold II with 13-15 hours of battery under normal usage patters, the HD2 is VERY WEAK!!!.
I'm contemplating sacraficing the sleak look of the phone for the extended battery.
Anyone have the ex battery? How's your battery life?

If you need direct push in your life, then I suggest changing 3G to EDGE network.
Difference is quite noticeable.
It sucks,and if you want better battery life don't use it.I returned mine after 48hrs.
All the advice is great,but....
-If I have go from 3G to EDGE.
-Lower the brightness almost to the minimum.
-Set activesync up.....What is the point of having so much technology? if I can not use because the phone dies.
I need real time email and 3G to work,plus all the stupid menus that windows mobile still has made me change my mind.Microsoft has been in the market for a bunch of years and winmo still sucks.
Do not get to impressed with the HD and the movies,cause the thing dies in no time.
Don't buy it and stick with android.
I end the day with about 60% battery life left with mild-medium usage. A few phone calls, some maps/gps, active sync every 4 hours, facebook every 2 hours, weather every 3 hours.
VERY happy with battery life on this phone
i went all day yesterday (my first day with it) so i used it alot, took it of the charger, at 7:30am, and plugged it in last night at 10:00 and it was at 39%. that was BEFORE i turned off 3g(i dont get 3g in my area) so this hd2 blows the iphone battery out of the water....IMHO
my last device was blackberry 8900.
that thing lasted 3 days with moderate use. compared to that, 15 hour limit does suck, and there are times I don't want to use the phone to conserve the battery, which makes rage, but oh well. now I always carry an extra battery in my pocket, so that's a bit better. but that doesn't make it okay.
with the 3g off, wifi off, auto back light,running the energy rom apr 9. unplug on 9 am use about 100 sms and 10 minutes phone call with all the auto data off,just manual check weather and email twice still have 80% after 3pm.
turn off voice commends - this will help
Its getting better
I have recently done a few things to help the battery. I adjusted the the screen brightness to a comperable setting that a friend of mine has his set to on his iphone3gs I did not do anything to the 3g settings or anything like that. I set me email to sync every 4 hours. But my hotmail I just click send/receive and sync it myself. I play music all day on my phone. Check twitter internet facebooks while music is playing and a lot of texting over a hundred sent and recieved daily. Before I made a few tweeks it would kinda die quickly but now it appears to be a lot better.
My batter DOES NOT LAST FOR CRAP!!!!! I took it off charge at 8:13 and at 10:30 i checked my phone, it went from 100 percent to 81 percent. HOW DOES IT GO DOWN 19 percent in 2 hours when i didnt even USE the phone, i just hit the backlight to check the time, this battery is unacceptable everytime i check the phone the percent has dropped

Do you leave 3G turned on? Do you have your e-mail and/or weather checking themselves automatically?
The phone can certainly be doing things that consume the battery, even if you're not manually handling it at the time.
I don't understand why battery life seems to differ so much from phone to phone. My battery life is excellent and I use it a lot. I do have to charge it every night but I expect that from a smartphone. It always lasts me throughout the day with music, videos, calls, texts and web use on 3g. I couldn't be happier with the battery life of my phone.
PLEASE give me good tips how to save battery? BTW im using ENERGY's latest rom with cookie 1.7. i dont understand why i have to stop my email and turn off 3g when this phone is MEANT for these features. theres no point of a having an excellant phone when you cant use its features to its full potentiol without having it die within 10 hours( with moderate use)
Battery is weird
The other day i charged my hd2 fully then got on an airplane all connections were watch from paris with love which looks great on the phone landed after an hour and a half and my battery life was down to 15 percent i think i might have a bad battery when i am in the car i leave it on the charge and when i am in the hotels that i stay in it stays on the charge or plugged into my laptop and thoughts??
Ok, yesterday I put my battery to the test. I decided to use my phone non-stop until the battery drained. During the entire test I had running the following tasks on Task Manager:
Opera---with tap vibration enabled
Messages
Active Sync
Word Mobile
Hotmail
I had:
Push E-Mail (hotmail) "As items arrive" (receiving emails approx every 5-10 mins).
Backlight Automatically adjusted on, with both battery and external power set at 40%.
LeoCpuSpeed app running at 998 MHz.
Constant changing signal strength from 1-4 bars and H to 3G to E and back to H(Inside the lobby of a building).
Weather, Twitter, Facebook and everything else to be updated automatically, each one being set to update asap.
BsB Tweaks settings in the pics below.
Apps Installed: see pic below.
Also had some texting, about 30 messages from 9:30pm to 11:00pm with notification set to vibrate and ring. No phone calls
So, if you think your battery was bad...this is how mine did
100% -- 8:25pm
96% -- 8:38pm
89% -- 8:53pm
83% -- 9:10pm
76% -- 9:27pm
70% -- 9:44pm
63% -- 9:59pm
55% -- 10:18pm
47% -- 10:37pm
40% -- 10:53pm
34% -- 11:10pm
25% -- 11:28pm
16% -- 11:45pm
8% -- 12:03am
0% -- 12:10am

Pretty much my battery did not last even 4 hours. Keep in mind I was browsing Facebook and XDA forums on Opera non-stop. Also noticed when the charge was at 8%, it started draining 1% per minute
My conclusion...I will have to get a spare battery cause a single battery can't handle my every day usage Have tried different Radios, but they all seem the same to me strength and signal wise. I haven't tried any other Custom ROM than KUMARS.
In case I forgot something I'll add it later on.
I also had very bad battery life, i have flashed a few different roms since ive got the phone about a week ago, and id have to say

Pal, how would you compare this rom with Kumar's in terms of Battery life?
My stock rom had slightly more battery life compared to Kumars.
I had terrible battery life with the Cell Evo ROM.
I have had terrible battery life ever since I had my phone. However, I am currently using ChuckyROM with 10.50.19_2 radio and it's actually getting me through the day now.
wow u had all that crap going on & it lasted about 4 hours and ur complaining? seriously???
how long did u expect it to last? large screen, 1 ghz processor and a constant connection online... i bet ur HD2 outlasts ur laptop
thats like saying, i filled up my gas tank before i left home, drove like a maniac, floored the gas pedal after every red light & stop sign but i expect my car to not run out of gas.
real world tests are more acurate... without all that on u should get a full day of "normal" usage...

Stupid question, and this is something that we all as cell phone owner for the past decade should know.. did you train the battery? i get 24 hours out of mine, with contstant push email on 4 diff accounts, texting all day a few pix, a few sites visited

Sure did, the max I can get on normal usage is around 10 hours though.
Battery Training
I do not believe the HD2's battery requires training. Older styles of batteries had something called a "memory effect", where a battery not fully depleted, then fully recharged, created a shortened cycle time.
Newer battery components, IE Lithium Ion, or Lithium Polymer do not have this characteristic. Accordingly, there is absolutely no need to "train" the battery.
Now the only requirement with the newer battery types, is to maintain a charge between 50-70% during long term storage (ie what your phone was charged to when first received).

got my tmous hd2 launch-day... battery sucked so bad I cried (on the inside too). Returned it for another (hard as hell as I had to call corporate and have them call a store and make them hold one when some came in) after 2 weeks and all battery problems gone. 2 days easy with 1 charge. and I am a bit of a media whore: videos, podcasts, web, push, etc.

mine sure did, the first day i got it, it went dead about 6 hours after i charged it..
2 weeks later and it was down to about 60% after a whole days use and it would die during the night if i didnt put it on the charger.
now its been about a month and now it will go a whole day and a whole night and still be in the 40%s in the morning.
I don't see the need to have all that stuff running continously but it seems that the battery lasted as much as it should. I close out all programs propperly when done but I have the screen at the brightest and still the battery lasts me 30 hrs on average. I don't think I could kill the battery in less than 4 even if I tried real hard.
currently using the rom bellow... not getting 10 hours on my phone... my life relies on e-mail. So few calls rarely any texts. But 4 e-mail accounts with each having a send/receive every 5 mins... with downloading the full e-mail. I don't know what to do...
You are correct that Li batteries have no true 'memory' but there is a bit more worth mentioning... Here is a great article on Li battery extension & calibration:

I do not believe the HD2's battery requires training. Older styles of batteries had something called a "memory effect", where a battery not fully depleted, then fully recharged, created a shortened cycle time.
Newer battery components, IE Lithium Ion, or Lithium Polymer do not have this characteristic. Accordingly, there is absolutely no need to "train" the battery.
Now the only requirement with the newer battery types, is to maintain a charge between 50-70% during long term storage (ie what your phone was charged to when first received).

my battery is horrible too, i cant last more than 10 hours without bareley using it. i took it off charge 7:30 a.m. took it to school, around 10 i texted a little bit used the camera to take about 10 shots (no flash), and i played bubble breaker for about 15 minutes. brightness was on 20...keep in mind after i close everything i fully close it through task manager.
around 11 my battery was at 65 percent. and i only USED the phone for about 25-30 minutes of light usage. i honestly dont understand how a battery can be this bad with a phone. the battery is HORRIBLE!!!!!
i got 3 different batterys exchanged so far, none of them work goood. i conditioned it as well... fully charged then fully drained then fully charged again
please help =( i dont even use my HD2 anymore because i HATE the battery, i strictly use my BOLD 9700 until i find a solution to the battery problem
NYC, the biggest issue with the HD2 battery is its low capacity (1230mAh), which is lower than most smartphones in general. Add the huge screen (a big battery draw all by itself) and the other power-hungry functions of a super-capable phone, and it can become very difficult to maintain a charge.
Now, in your case, I'd suspect that you have something that's updating data in the background, at least once if not repeatedly. Twitter, mail, weather, etc are all possible culprits. Even if they only update once in the morning (for example), they flip on your 3G connection which then remains on until you switch it off manually. Bluetooth and wifi also drain the battery quickly, even if they're just "on" and not being actively used by you.

Sit! Goooood battery. You're such a well trained battery, yes you are, yes you are! If you keep my phone running all day I'll give you a nice 1 amp charge, yes I will, yes I will!
couldn't help it.

I get from 7:45am to 2:00am pretty regularly out of my phone--push emails, IMs all day, about 200 messages sent/received, 120 min of calls, and probably 2 hours of browsing. I have wifi connected from 6pm-2am.

That is really hard to believe...specially the wifi from 6pm to 2am
My phone drops to 11% after 24 hours of doing nothing with it besides fiddling for about 10 minutes. The signal bar is 3 ~ 4 bars at all times on a 2G band. I'm not certain why it's this crappy even though I pretty much leave it on standby. Any ideas?
Hi all,
Just switched from xperia x1 winmo to galaxy.
I love my exchange and cant miss it.
So I set it up on the galaxy. Left it in good hsdpa coverage area over night for 8 hours after fully charging it. Battery now at 76%.
This is not so good... My xperia was significantly less consuming.
Moreover, sometimes push is sluggy. Some maols from this night only appeared after opening mail app.
I am quite disappointed...

now it is 6h30 since 100% charge
Battery down to 33%
Android reports:
Display 36%
Battery in Standy 23%
Android OS 16%
Phone in Standby 15%
Android System 5%
Task Killer 4%
Maybe 5 mails arrived, opened mail app 3 times and 3-5 opened for very few minutes.
Had the phone in bad reception area (1-2 bars) most of the time.
Still, this is really bad!
If you do a search, you will find many posts advising that the full potential of the battery will not be available until at least 5 complete cycles.
This means battery fully charged, then run to fully empty, then fully charger again, equals one cycle.

this is bloody strange, I was thinking the more the battery gets heated up it looses it's lifetime!!!

well, better now, but my old Xperia X1 still beats the **** out of the Galaxy in terms of battery & MS Exchange Sync reliability...
Samsung: 2 days only under optimal reception conditions
Xperia: 3 days any which way
new test from last night:
charged to 100%, clean reboot, exchange sync on
7 hours
=> -15% battery
I conclude
The SGS does not survive one working day.
Recharging twice a day is not acceptable!
I activated the push today so I will see how long it last
For the moment I am at 81% of battery and it has been unplugged for a little bit more than 3 hours
I watched also 20mn of french news so 57% of battery used by display
I think it could last the day if I don;t do anything to stressful
there is a very specific way to charge this battery right out the box to optimize its full potential ASAP
so you turn on the phone for the very first time and use it on whatever battery power thats left. then use it to the point which it shuts down itself. now turn the phone back on again, and plug in the charger, keep using the phone but with the charger still plugged in. when the battery meter indicates "FULL". unplug the charger. and repeat these procedures twice.

It's been now 9hours and I still have 43% of battery.
42% of display (2h11)
19% call (10mn)
Android system ( including sync) 15%
...
So for sure it won't last more than 1 day but you should be able to last 1 full business day
I even switch on the bluetooth to send some mp3 to my wife ( it failed ... she had my old iphone and I forgot it wasn't possible ), the gps for few min ...
I am also listening music for around 2-3 hours
EDIT : by the way, I was in front of my laptop and half of the time the mail arrived before on my phone and I got all my mails
still got the JF3 ROM, but heard that newer ROMs may have trouble with Exchange.
Email works ok for me, but appointments sometimes take tooo long to sync.
My office is well-shielded (lots of steel), so only got 1-3 bars, sometimes switching HSDPA and EDGE.
However, my previous phone had to endure the same.
7h18m since unplugged, battery at 74% still remaining.
Display: 49%
Cell Standby: 24%
Phone idle: 17%
Android System: 4%
- Exchange sync is on.
- 2x Google account, email, contact and calendar sync is on.
- Updated 4 apps from market.
- Display on for a bit more than 35 minutes in total since unplugged.
- Twitter and facebook sync is on. Refresh every 15 minutes.
- Weather service refresh every 2 hours.
I've still only once not had the phone last a full day on one charge, and I use it quite heavily. Playing games, taking pictures, reading feeds etc.
I don't know what you call heavily but after 15h my battery is a 7%
I have 3h of display which takes already 38% of the battery
35mn in more than 7h is not what I would call heavy ... especially if you read, play games, take picture ... unless you do so with the screen switch off
now for the OP I guess this bad reception can explain the ewak battery but not the difference with the previous phone .... Just mean that the battery was better on the previous one
the SGS is useless.
My Xperia could do email & exchange sync better and browse some web pages.
The SGS has trouble with exchange (tasks!) and COULD do browsing and apps better. But if you actually start using it and looking at the superb screen, the battery runs empty quickly.
So what is the point in having this device? Honestly, this is quite frustrating.
[Update]
9h20
100%->81%
radio: 74% (why does it translate to "Akku" in German?)
Telephone: 23%
Email: 2%
one email came in during that time
I just read of a guy on another forum who got 8 1/2 days out of one charge!!!!!
I'm getting about two days, had the phone three weeks and the battery has improved, at first I was loosing 30% in only a few hours. I initially starting turning off email, then once-per-hour to save battery, but now after a few charges I can leave both Gmail, gTasks, Exchange on push sync and a few widgets which update at regular intervals... I still get two days of average usage. Not like my old Nokia, but then again the Nokia was nothing like the SGS
Note, I do have a profile which turns off autosync between 23:00 and 06:00, and I use autokiller, but apart from that it all stock.
now at another place with full bars most of the time:
11h40 since charging
50 minutes telephone call
=> 48%
69% goes to calling
22% radio standby
...
mails came in with 2-3 minute delay ... sometimes its rather instant ... well, WiMo and blackberry can do better

unfortunately, this is what major/ popular finger touch screen device deliver, be it Apple iPhone, HTC, and SGS.
I'm surprise to know Experia can last that long, is that the Winmo version that that uses stylus? the pressure-base (or rather stylus based) touch screen have a very long battery life.
PS: I have around 100 mails in 8 hrs, and my phone need a charge during lunch in order for it to support me until night.

I was told that Blackberry Storm and Storm II have the same battery performance like iPhone and SGS.
WinMo 6.5 is using stylus based. I curious how long can WinMo 7 battery life last with that finger-touch based screen.
I don't see how resistive screens vs multitouch screens matter in this case.
Looking at the energy info, radio in standby seems to consume a lot. And also phone in standby. The phone's screen is on for very few minutes, just to quickly read some mail. Most of the time screen is off and push mail service is active in the background.
Besides, Samsung talked about OLED and SOLED as SAVING energy ...
Well, maybe it is just the OS.
I think WiMo 6.5 is just a better OS. I wonder what the HD2 is like.
To bad the original WiMo 7 has been canceled. This touch & fun cellphone trend is horrible!
