This is how fast my battery drains... - HD2 General

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
forum.xda-developers.com/showthread.php?t=667601 this rom has outstanding battery life. i would definatly give it a shot.\

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:

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!

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?

Average Battery Life ? ? ?

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.

Battery Drain HD2?

Anyone else experiencing excessive battery drain on their HD2?
I am interested to know if this is just my phone or if it actually just chews through that much juice.
I have had windows mobile phones for several years so I know all the basic ways to keep battery drain down.
Stuff that I have generally found:
1. If I keep the screen turned on without it going blank I lose about 1% every 2 minutes.
2. If I am browsing that figure almost doubles.
3. My old Touch HD used about 5% battery overnight when in standby but this phone will go through about 25%.
4. The phone gets really hot when browsing (much hotter than my old Touch HD)
I have tried flashing ROM's and Radios but nothing seems to help.
I am not running any software on the phone that I wasn't running on my old HD1.
I have only had the phone for a week so I am not sure if this is normal but I would be very surprised if HTC released a phone that lasts for only a few hours on one battery.

-1% every 3 minutes
-4% during the night (when i'am sleeping)
MAXIMUM : 45/48 HOURS

I wish I got 2 days
we really need extended battery ,hd1 battery was much more better.
Good mate but yes i agreee HTC has come up with a battery eating device this time around. My device on full charge just gives in around 8-10 hrs. This might be dat my EDGE is on and 7 mails accounts sending mails back and forth.
but truly i think that HTC better look into this very seriously cause more and more ppl are suffering in this battery drain..
Any of flashing roms and radio not helping either... did a complete hard reset but no step up
HTC come with longer battery battery for bigger devices soon......
The only solution i see now is get one of those extra battery worth mind bogling £52.87
I've had this problem ever since flashing to 1.66, I flashed the radio to 2.07.50.27 as this was said to solve the problem but it hasn't made any difference after a few days of use. My battery life used to be significantly better when I was on the original stock ROM, so much so I'm considering going back to it
I also know all the tricks as to clawing back the battery drain, my phone is idle on my desk at work most of the time and I don't use Wi-Fi, all the location stuff is turned off as are weather, stock and other updates plus my screen is set to 30% then off after 60 seconds. Despite all of that I lose 1% every 2-3 minutes
It seems to me that perhaps the radio is checking for reception pretty much constantly rather than say, 5-10 mins perhaps? This used to be a problem on my old Blackberry Storm but a few fimware updates solved it, eventually!
The only other thing I've noticed since the update is that once the battery drops below 50% or so, the drain seems to slow, I don't know if this is perhaps because the phone goes into some sort of semi-power saving mode?
Suggestions/hints welcome! I've had a semi-thorough look into this on the forums and tried most of the suggestions but still the problem remains. Will battery life improve after a few charges perhaps as this was a trait of my Storm's battery, the more you charged it the better the day to day battery life was (and no it wasn't because I had it plugged in all the time! Over time the general charge just seemed to improve when roaming).
Thanks!

You need to indicate what services you have running. Do you have any data services running eg: location services, push mail, weather? all of these have a bearing. In addition, network services can also drain a battery, especially if the signal is weak and the phone have to search for a transmitter, or 3g services.

That is a very interesting comment. Although since upgrading to radio 2.07.51.05_2 I have had very good battery life, I too have noticed a slowdown after 50%

Nothing is turned on, everything is set to manual.
As I stated I know all the basic stuff. I understand that all these things have a bearing on battery loss.
Everything I stated in the first post is for when I have nothing running. The phone is just sitting there running sense, thats all.
I have had my HD2 for a few days now. I am on Vodacom in South Africa.
I have not had a problem with battery life.
Yesterday i unplugged from the charger at 07:00. I spent about 1 and 1/2 hours of talk time on the phone, it was permanently connected to 3g doing weather updates etc. Sent and received a couple of sms's. Also played with a few tweaks and reboots.
When i got home at about 18:00 i had over 30% battery. I then surfed the web for over 2 hours to drain the battery.
try setting Network Selection to Manual

Same here with and without stock ROM.
yeah.. the phone is a battery sucker.... another cons of HD2....
This is very interesting to read because I do not have this problem. When I left my HTC HD2 on last night (I woke up at 4 in the morning to get something to drink and unplugged it) and then woke up at 8, it was at 98%. That means it went from 100% to 98% in 4 hours. Not to bad imo.
I am now at work and it is 15:34, and I am at 87%. I have made some calls, watched some videos, send a few text messages. Not much (I am at work so I got other things to do). So 08:00 (98%) - 15:34 (87%) - that's 7 and a half hours, with some calls, text messages and a video.
I am pretty sure when I get home at 18:30 the battery will still be above 75%. Then I connect to my wifi at home, refresh twitter, weather, browse the web a little bit, check e-mail etc. So that will drain my battery a little more.
But overall I have not had any problems with my battery life. I always make it trough a day, and never have a problem like 'damn my battery is almost done and I am not near a charger'.
Some info that might help:
I do not sync ANYTHING automatically. I still have some things to do with my Vodafone contract and do not have an unlimited plan yet. I only sync at home on my own wifi connection. For me this is not a problem, because I only need to refresh the weather each morning to see what the day is going to be like. Twitter I only do when I have the time. Stocks I do not use.
I have screen brightness set to automatic.
I am on 3G most of the time.
I am running the official 1.66 Dutch ROM.
I have some tweaks, games and programs installed.
I hope you all solve this issue, because it just can not be that my HD2 has a good battery life, and your HD2 not
Kind Regards
EDIT @ 17:00 still 87%.
I am in a 3G 2100 only network (I don't have 2G functionality).
ROM: Artemis 3.0
Radio: 2.06.50.23_3
Customization: Seiya 6.5.5
I don't leave any automatic updates on, except for my e-mail account every 2 hrs.
I never close my connection.
The drainage overnight is -3% (8hrs).
The battery lasts at least 12 hrs of intense usage.
Normally I have to recharge every second day (e.g. I charged last night, I answered a few calls, I did some IM and browsing and I still have 73% left).
For a phone with a 1 GHz processor, a 4.3" screen and a tiny 1250 mAh battery I find the drainage is rather decent.
Mind you, I ALWAYS do at least one full charging cycle to my battery after flashing a new ROM. I mean: full discharge, battery out 1 min, full charging in OFF mode, battery out 2 mins.

I have seen this process recommended a couple of times now. What is the theory behind it if you don't mind me asking?
maybe its also becouse some of us couldnt wait using the hd2 when they got it (like me) before it was fully charged for the first time
anyway my battery life has improved a little bit, i was at 74% this morning and did a lot of browsing, installing, tweaking and now its at 3%. it used to be much worse
I have battery consuming problem from time to time.I did everything:
installed new stock rom 1.66;
transfered all data which phone is using from card to phone memory(pictures,icons,sounds.etc...)
all updates are done manually;
Gprs connection is swiched off on the idle after one min;
One night it is loosing from 2 to 4%;
another from 30 to 40%
and it is eating memory from 10 to 15mb
I think that it is radio which is causing battery drainage so fast(to much communication wit a base stations,because when I am checking spb wireless monitor in the morning,there is no any data traffic.
I hope they can solve problem,because it is getting me mad and crazy
Try setting the screen brightness to 10-20% (on battery powered)
and dim backlight after 10 seconds (on batter powered).
It helps a lot, at least for me.

I have seen this process recommended a couple of times now. What is the theory behind it if you don't mind me asking?

as far as i know, the battery has an integrated digital circuit (ic) which estimates the state-of-charge (soc). the procedure resets/calibrates the ic to obtain a more accurate estimation. since the radio rom is in charge with the power management (among other things), by changing it you decalibrate the "gauge".
i don't know if i've got the theory right but i tested this myself and it surely works.

Battery Life??

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??

Battery w exchange on

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...
Sent from my GT-I9000 using Tapatalk
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!

Battery charge too short?

Hello, Im noticing that the battery charge is too short.
I disconnected it from the computer (battery at 100%) at 23:00. Inmediately put it on fly mode (all services disconnected, low battery consumption). When I wake up at 9 o'clock, the battery was like 60% (and disconnected fly mode). Now, at 11, the battery is like 40%...
Yay, I usually charge it every night... I don't want to charge it twice/day.
I don't know if trophy have now battery problems or is just wp7.
Anyone with the same problem?
If you just got your phone, I think the battery was not run in yet. I have the same problem for the first 3 charge. Now battery life is slightly better than my old omnia 2 which last me 12-14 hours as I am a heavy user.
It have like 15 charges. It usually takes longer to uncharge, but not today, I will test it more days.
Thanks for you reply.
Sounds like there could be something wrong with it. Mine is a lot better than the HD2. I'm not a heavy user, but I get like an hour of music/radio on the way to work, then a few calls and SMSs during the day, an hour of music/radio on the way home - and it's still on like 70% when I set it to charge before bed time.
Update: seems location services cut the battery life in half. MS needs to do something about it to make it more efficient.
battery ??
How can i check how many % of my battery left
I've charged my Trophy about 4 times and the last time i overcharged just like in formating a battery ( i know the bqattery in Trophy doesn't require it but I can't hurt can it??).
The last time I charged it was on the new years eve just before midnight between 22-23. Now the battery has been showing the "critical battery mode" thingy for about two hours. I admit that I am not a heavy user however per day I make couple of phone calls, I make a few SMS and use the 3G mobile network/ WiFi(if available) to check internet write a mail, Facebook etc. and about 30 minutes / per day of music...( need to say that I don;t use the standard phones which came out of the box but Seenheiser 515HD model )
I have set the 3G and mobile data etc off, the brightness level to automatic, set the theme to dark etc. to save the battery as much as I can.
