battery life

Hei all of you
It seems that the legend has been released to some people, and i was wondering what you guys get out of the battery.
I am currently on a Diamond 2, with 1100 Mha battery, and currently get 1½ day out of this, and i want this to be an improvement. The legend, with 1300Mha, OLED screen and newer cpu, sounds like it will be a lot better, but some review mentions the battery life to be really bad.
I am using my phone for 20 text messages, psuh mail, no phone calls and only visit a few websites on 3G. No bluetooth, wifi or GPS. What can i expect of this?

i'm sorry if my English is not good enough,
but i've the HTC legend since Friday, and Saturday i did a simple test, i put the mobile phone to charge Friday night, Saturday about 12:00 pm i disconnected the charger and i've turned the wi-fi, gps,and bluetolth off, only the 3G network was on.
I had also ebuddy running on the background, after 4 hours i didn't touched the phone, and my battery was about the 25%
And the full charge time was almost 2 hours.... i went back to the shop where i bought the phone, they changed my battery and the did a hard reset.
The battery performance is now a little bit better, but it has not the same performance as the iphone 3gs.

I think the first time you run your phone it will consume the most power. So it's not the right time to test. I suggest you fully charge and fully consume the battery 2-3 times and then put it for a test.

Full capacity of a battery shows up after 2 months.
You will pass from 1 day to 3 days

So here is one short statistic after second charging.
14% of energy left in the battery after:
39 hours since last charging
2 hours of display on (35% of energy)
37 hours of phone connected to the cell (36% of energy)
13 minutes of calls (13% of energy)
Phone used for me "as normal" - cca. 10 SMS, 2 hours of mp3 and FM radio, one hour of net surfing, running sync with Gmail and Google Calendar.

Yes, it is period of 1-3 months to get full capacity of the battery, but in first few usage, you can fully charge and discharge battery.
I have a one day of full usage of the phone (wifi always on, twitter, e-mails, calls etc.)

Getting better
It's getting slowly better with each charging, second week and I'm on two days. Everyone is using it in a different manner, but my battery improved for about a 70%.

got the legend now for 2 weeks and loving it.
Battery life is good, don't expect to go 2 days intensive use without recharge but no phone with these function have this.
I can easily go with one to two day with occasional wifi, gps use and keep 3g or sync on settled on 1 hour intervals while playing some games using apps etc
Blue tooth i haven;t tried but like any phone the power munchers are wifi, blue tooth gps and 3g.

wifi should save lots of power compared to network operator connection
i use wifi at office, and with extensive usage, i can get about 8 hours straight, that is pretty heavy, the screen barely got to sleep

I have tested the battery in plain sleep.
If the device has wifi off and mobile data off (and no sync, ofcourse) i guess it lasts for a week - 10 days. But then you cant use wifi or mobile data.
If you only let it be in stand-by (screen locked and off, no data or wifi or gps or bt) it last quite long, probably close to the stated 300-400 hours in the manual.
In real life that translates to 3-5% battery drain (tested by me for 24h, only sent 2 sms and talked on phone for 2 minutes) per day.
But in normal use, wifi will drain 5-10% battery per hour and 3g/gprs with autosync drains 2-5% per hour depending on net.
No device lasts for more then a day or two if you acctualy use the device.

I have had my Legend for a week and a half now and the battery life is also getting better with each passing day. I can easily use it for a day and a half with quite a lot of WiFi browsing, and up to 30 or 40 minutes of call time. I'm really loving this phone!

Hi fellow Legenders,
i've had the phone for 4 days now. i am having issues with my battery. I have noted some points that i'll share & hopefully find a resolution for my dismal batt life. I have bluettoh on all the time, but it shows very little drain based on BT alone. Other than that, this phone ROCKS!
After full 8hr charge, the phone lasted approx. 13hrs 38mins before reaching critical level with the following findings:
On 08 April 2010
1. Voice calls used 50% batt – 36mins 11s call time.
2. Display on approx. 30% brightness used 21% batt – on for 1hr 10mins 15s
3. Cell standby on 3G used 16% batt – on for 13hrs 38mins (no signal 1%)
4. Phone idle used 8% - on for 12hrs 28mins
5. Bluetooth used 5% - on for 13hrs 28mins
After normal charge till batt 100% (about 3hrs), the phone lasted 15hrs 12mins 41s before reaching critical level
On 9th April 2010
1. Cell standby on 2G used 50% - on for 15hrs 12mins 41s (no signal 3%)
2. Display on aprrox 30% brightness used 18% - on for 29mins 35s
3. Phone idle used 15% batt – on for 14hrs 43mins 5s
4. Voice calls used 10% batt – on for 4mins 14s
5. Bluetooth used 7% - on for 15hrs 12mins 41s
Looking forward to better batt life as the days go by.
cheers,
Su

Very poor battery life for me.It has 7-8 hours stand-by.
1.Every 5 mins e-mail control.
2.Weather with auto update.
3.Friend stream.
4.Background data and auto sync.
5.Enable always-on mobile data
6.3G
I don't understand whats going on.If i left device when i go sleep with full battery after 7-8 hours i look it.It shows me only left %35 battery.
After disable all auto-uptade and 3g its over 1 days.
My hd2 had 1230 mah battery and super big screen and 1ghz processor.It was using %10 with same usage.
Legend has 1300 mah battery and small screen and 600 mhz processor.It uses %65.
Can anyone explain this sucks status?

I m using the legend... and a hd2 as my other device. would say the battery life for the legend is really dismal...

I am happy to report that my phone batt life has improved tremendously since my last charge. I installed OS monitor & checked to see what might be hogging the batt, & discovered some program was keeping my CPU running inthe high 70's & above continuously. I killed that program, fully charged my phone till 100%, restarted the phone for good measure, & with BT on permanently, more than an hour of wifi usage, about half an hour of phone calls & about 30 smses, after 24hrs, i still had about 24% batt left.
So it has definitely improved by leaps. Hope that helps others who have similar problems.
cheers,
Su

it will be good if you can share what's causing the high cpu usage ...

Oh sorry i forgot. it was OpenWatch for BT watches. It has a problem currently with HTC Legend & SE MBW-150. It doesn't have the full functionality as yet for some reason. The reason it ran the CPU load up, was because i had turned off my watch by accident & set the program to search & connect to the watch. My folly really.
cheers,
Su

Nice battery time
I've bought and charged my phone last Thursday. GSM only, using WIFI every day for 15-20 minutes, 10-15 min talk, and it's still at 35-40% after 5 days. I've got a magic battery or what?

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??

This is how fast my battery drains...

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?

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.

[Q] Focus battery life after Mango 7720

How is the battery life compared to previous state? Better, worse or about the same? Please vote

It will be the same for the first 3 days and then gets better by a whole one more day (Don't know why).
For me the counter at the 1st 3 days said it will last for 1 day and 18 hours now it says that it will last for more tan 2 days and 18 hours and some times 3 days and 5 hours.
I tested it and it lasted for 2 days and 11 hours and there was still 17% of battery life (Lite usage , some 3g usage and listening for 30 minutes for music and around 2 to 3 calls of 15 minutes total).
Hope that helps

It does, thanks! Replies are welcome and there's a poll on top so please vote

I leave WiFi and data connection switched on all te time ... I used to get about 18 hours ... Still get Te same ... Comparing 7720 RTM with official mango update ...

Battery life on my focus with mango and even before mango has been better than any other smartphone ive owned. I cant complain at all.

I was going to post a message on the battery too.
Poll is a great idea.
I just finished charging it after installing Mango. I will see how much it lasts.
I wanted it to drain out and recharge it so I can see how it is with Mango. It didn't gave up easily.
My initial impression is that battery is improved.
However, when talking about battery life, it's crucial to keep in mind what services the phone is using and what apps are installed.
For example, things like sound enabled for key presses, or having WiFi on or off, whether you play games, what apps you run, etc are important.
For my test, I want to see how long the battery lasts with a very basic usage. WiFi turned off, without running too much app or play games, giving\receiving few calls(I do not talk too much on the phone).
I heard for example that Samsung app Now drains out battery pretty fast.
Also, lack of signal in some areas, also means alot for power consumption.

6 days + 7 hours
Usage:
no WiFI enabled
no games played
max 2 hours of talks in total(I talked once like 1 hour)
How does it sound to you?
For me it looks fine although I am wondering how much would it last if I have Wifi enabled(for the same amount of talking duration).

6 days, What?
I only get 3 days and 15 hours if not using the mobile phone at all.
Can you please post a screen shot of the battery saver

I am in the 7th day actually now
The statistics displayed in battery saver are very wrong. I am not sure how it computes the remaining time.
When I posted yesterday, it showed 6 days since charging and only few hours remaining.
Now it says, 7 days and 1 hour since charging, remaining: "less then 1 hour", remaining battery life: 6%.
Last time I charged, I noticed that battery doesn't get to 0%, most probably it needs some energy to preserve data, so it will probably only keep me for few hours today.
I will post a photo soon, right now I don't have other device to take a photo of it.
Last time I fully charged the phone was when it was completely empty. Maybe it's important.
I can only hope the battery life won't degrade in the next year.

Ok, so now we have some votes so I can share my bits and why I started this thread.
Before 7720 I was on 7660 (Mango Beta1, not 7712)
The battery was certainly better than in NoDo. Actually, I'd say my phone had the best battery lifespan in 7660, than in all other versions.
7660:
Standby: 3+ days.
Night stand-by: 3% consumed (cca 7-8h)
On average use: 1 day and 20h
For me, average use means:
- Cellular data connection on during the day (I switch it off during the night)
- Some wi-fi to check new apps, say 20 mins daily
- About 1-2h playing.
- Minimal calling (several minutes).
7720:
Standby: almost 3 days
Night stand-by: 4%
On average use: 1 day and 10h
Stand-by means no data connections.
As an observation, stand-by time is almost similar. There is a noticeable drop in battery time once data connections come in play (cca 10-20% for me, compared to 7660). I am not going to revert to 7660 to re-test.
One more thing: after upgrading to Mango, I had AccuWeather app installed and running in background. I had to disable it because the battery life was getting under 24h (actually more like 20h). So if you have apps that run in the background, that might be one of the reasons why the battery life dropped for you. Once I disabled it from working on the background, I'm experiencing very similar times to 7660, but still the data connections consume just a bit more.

How are people getting 3+ days!? When at 100%, my Focus usually says like 12-13 hours. I have a Gmail email account set to push, and a Hotmail account set to receive email every hour. I have Facebook, Twitter and LinkedIn linked on my phone. I have Messenger and Facebook Chat set to off. I always have wifi/bluetooth off, unless I need it for a few minutes.
I am thinking I should flash to 7004 again and update to Mango from the beginning.
I walshed my phone for Nodo, then did the fix, then used the windowsphonehacker method for Mango and got the "Samsung Update" when Mango was released.
Thinking maybe my install is just a little off due to the route I took to get here.
Anyone else have battery life as bad as I do? If I use my phone non-stop for like an hour (people hub, web browsing, facebook app, etc...) I can burn through a ton of battery.

Make sure to do a reset immediately after the update to the *official* Mango (not the tricked one).
The BL seems to be much better and is a small cost for the rewards. You will erase your phone, but it's worth it. The BL seems to be much better than NoDo.

To increase battery life when you have data connections on:
- keep the brightness to low
- keep the ringer on vibrate when you can
- disable background apps
- don't keep applications opened in the background
These save me a good % of battery on a daily basis.
Also, unless really necessary, disable data connections during the night.
@rkremers: with the above settings and no data connection I get 3-4% loss evey 8h or so. If you calculate, that's about 12% per day. Which gives about 9 days for standby, as someone else on the forum was saying, which I incline to believe. This weekend I will test this too. I won't touch the phone at all until Sunday evening. So I'll have the power consumption on standby for 2 days.

dang enderpsp... Now I'm for sure gonna flash to 7004 and start from scratch, to see if it gets better. Probably do it Sunday sometime due to busy Friday night/Saturday.
Thanks for weighing in...

You're welcome. Keep in mind that a "tired" battery can also be responsible. I see lots of wrong advice given across the forum.
How to Prolong Lithium-based Batteries is a long read, but in the long run, you'll benefit from it, as a lot of devices use nowadays these types of batteries, including cars!
LE: As a refresher for me, I searched again and found this. While it's not as detailed as the one above, it contains good advice.

so, I flashed to 7004, then let Zune upgrade to Mango... I'm at 95% battery now, and it says 1 day 5 hours... 1 day 10 hours with battery saver on.
Not sure if it will actually last that long, but before I did this, it would say about 13 hours on a full charge with battery saver on... so clearly my phone did not like being walshed, unwalshed, hacked to mango, etc... Guess in the future I'll install leaked versions of WP7, but go back to zero when they officially release.

I finished the weekend standby test (2 days). This battery is 9 months old.
Setup:
- Battery saver off
- No data connections/wifi
- Sound on
- Low brightness
- No alarms
- No background apps
- No touching the phone
After 24h: 91%
After 48h: 79%
Had a phone call (didn't answer) and one alert (didn't dismiss), in the second day. After 24h I just turned on to check battery status (<20s).
The end result speaks for itself, approx 10% battery per day. So, it can give 9+ days on standby.
Next weekend I'll do the same test with battery saver on and update here.

I just got a Samsung Focus and the battery seems to lose power at the rate of 2% an hour. Is this normal? data connection is not active, no games, no youtube videos just a quick e-mail check and 2-3 min call.
Is this likely to improve after a few more battery charge cycles? I have followed all instructions like disabling location services and background apps.

How is the antenna signal? What type of connection?

Antenna signal is pretty good 4-5 bars. Just regular connection not 3g. E-mail auto syncs have been set to manual.
Battery seems to be original Samsung.
