Now, I know that it depends on what programs are running, like... whether you have any minimized or in the background, but on an average 1500 mAh/3.7V battery... what is the amount of use time that one can expect...?
Let's start a thread on this subject... listing the type of battery, approximate age of same, the names of the files/programs you run & use in a given day, and the amount of hours of overall use you get before you have to recharge or switch it over to a new/fresh battery. This way, we'll all have a better idea as to what programs really drain the phones, such as when you leave the WiFi and/or Bluetooth "on" all the time - waiting to be used (a sure guarantee to have a dead battery in a matter of hours).
We can subtitle this one under "The Cost of Staying Connected" (not including air-time charges or monthly fees).
i think my battery life is terrible... but its understandable. usually i run wifi and phone all day long.. the only reason i run wifi on all the time is because i have a feeling everytime i don't... somehow i get charged for using evdo (from bell in canada)... but i dont?? its really weird because i used to always get these random charges.. but ever since i kept my wifi on all day everything is all good. i have the original battery that came with my ppc 6700.. and i use the phone around 40-70 minutes of talk time. no real apps running but a few games of solitaire here and there. but if i were to talk non stop it only seems to last like 1hr
my battery life is like 10 hours and i always have to charge it when i get home from work or school or ill be doomed the next day
Since upgrading to WM6 (thanks helmi), my battery life has found NEW life. I used to have to charge it everyday: no wifi, 50% brightness, screen off in < 1min, etc. Since upgrading, I can run it at 100% brightness, screen off in 2min, and I don't have to charge it every day.
This is with the factory battery, and an eBay replacement sometimes used.
always running: freestyl (flashlite), sms threader, mbutton
phone is usually locked with s2u2
most use it usually gets is me checking the time
update rom from verizon, .net 3.5
ever since i updated the rom, it seems like i only get <24 hours per full charge (battery purchased less than a month ago)
w/o wifi or bt i get about 3 days however it depends on what version of windows are you running have you guys updated to the new 6.1 or 6.5 biulds?
My battery life its very short but, i use my apache with core play at my car with my kids plus the wifi, and blue with hand free, soo i've to conected every day, and i'm use 2batterys
original battery... i got 3 days on standby.. and 2 days in normal call usage...
but
with wifi my battery gets drained to the bone in 40 minutes LOL
thats all =D
About twenty minutes. I know I need a new battery >_>
... that and that I'm surprised I've got over 240 hours clocked in the lifetime call timer.
Using a 2600mAh 3.7v Battery
I had my extended battery for about 2 months now.....
TCPMP:Battery life is close to 5 hours on the lowest brightness level using headphones & on speaker mode I get about 3 1/2 hours.
Making Calls: I sometimes spend about 2 to 3 hours on the phone & that leaves the battery to about 70% or 60%.
Wifi: I don't use it for a very long time, but when I do it could be about 1 hour and that can leave my battery to about 80% to 70% when done.
Videogames: I use mainly the Morpheus(emu) usually about 20 to 30 mins and only seems to leave it close to 90%..
With random use I normally have to charge the battery every 2 or 3 days... I play with the phone quite a bit tho! Mostly text messaging (turning it on & off about 20 to 30 times daily).
With my 2 normal batteries? I think they need to be discarded soon lol!!!!!!! Wifi will deplete them(each) in about 4 or 5 mins tops!!! TCPMP about 10mins(screen on at its lowest with speaker) & 15 mins max(with headphones & screen at its lowest brightness)... Phone Calls? about 20mins tops(with the screen turned off)!!!!
So.... I strongly recommend the extended battery on Ebay for about $22(shipping included) so that you can enjoy the phone alot more!!!
I try not to keep the phone on the charger until the battery has depleted to about 20% when the warning comes on and fully charge it always!
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
-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.

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.
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??
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!!!
S
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.

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

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!
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 ...
Sent from my SGH-i917 using XDA Windows Phone 7 App
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.
