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!
I was wondering, if I constantly am killing running process and they are always reloading (voice input, settings, gmail, market, etc), will this drain my battery faster? I'm at 76% with light use from a full charge and the phones been unplugged for around 4 1/2 hours.
That seems normal. mine usually dies within 6 hours, with all settings off. i think i need a new one. under battery settings it says display used 67 % of my battery life and for display time on it says 28 minutes
I've got my display using 73% followed by live wallpaper with 6%.
I mean Display% being higher just means you were actively using your phone more... or you set your timeout too high.
I don't think the actual restarting of the apps uses more battery vs them just running in the background all the time. Unless for some reason they restart almost instantly and you are constantly mashing the kill all apps button then maybe?
As far as your phone dying in 6 hours, that does not sound right at all. Mine definitely goes quite a bit longer than 6 hours consistently. It is currently at 38% battery after 17 hours 24m, with display having used 46% with 55m24s on. Part of that was while it was full brightness when I was outside. I have been at work though so its largely been sitting on my desk. Even when I first got it and was playing with it a ton it went well over 6 hours on a charge.
Some people do seem to have problems with battery life and I can only assume there's a bunch of bad batteries out there, or they are really hammering it..
I used about 25% in 6 hours today from normal usage* and that's even after driving around for half an hour streaming last.fm over bluetooth via 3G.. Sync switched on, wifi off, twitdroid running in the background. The only special thing I have is the setcpu idle tweak.
* Fair bit of browsing, some twitter, the usual 'ooh look you have a google phone' impromptu demos..
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?

I can't believe this . I wanna just 24 hours stand-by.I hate to charge it everyday two times.
My battety lost One percent in one till ten minutes. I alrrady tried to delete the batterystats but it doesnt help. Any suggestions?
Were you doing anything on the phone, when it droppped 1% in 1 to 10 minutes?
regards
Nope. Even in offline mode it drops that fast.
You tried restarting the phone? I'd prolly try a factory reset after that if nothing changes. Other than that I have no ideas.
Regards
I tried restarting, different firmwares, flashing back to stock rom with nandroid. Nothing helped...
How old is the device, and how many times did you charge it 'till now?
I'm on my 4th day since last charge, and standing at 43%.
In anthing battery related, this phone is god.
Hey hi,
I know is frustrating.. but I think we can fix it ..
First we have to figure out what is taking the charge on your batteries.
First check if wifi or bluetooth is turned on. If yes turn it off.
Bring down the brightness of your screen
go to WIFI Settings and turn off the network notification
install Advanced task manager from Market and see the background application. Some might be running as default. But kill all for safer side.
When ever you open an application it stays on the memory u have to kill it using that tool.
OR
IF nothing worked jump into an other firm ware update. I have this android 2.2 i9000xxjp3 Its working very smooth But its an beta version. I am quit fine with that ..
I already did this. And nothing helped.
Similar to my thread:
http://forum.xda-developers.com/showthread.php?t=730302&page=2
Autokiller does not have any effect. I uninstalled all task managing sh*** and I can't find any significant difference.
However, I found after 5 charging cycles it was better than before (now 2/3 day instead of 1/2 day).
okay that's nice 2 know
I got eleven hours... Will see if ut gets better after some cycles. But i rly think its a battery or phone defect.
Hi i just did a battery test on 10 mins of wifi browsing battery drop from 65 and now 60 with 45 pages. Can someone do a similiar test to compare cause i think mine also a flaw set from samsung thnx in advance
How old is your SIM Card?
I know some old cards can drain battery hardly cause there is no power saving implementet, newer have better power management.
Maybe the card is defective. If you can, make a test with adiffetent SIM Card.

The other day, My battery was pretty low, less than 10%. I checked battery usage, and everything was okay. But I made 10 mins of call, and that used 23% of the battery, and that's from a full charge ;
EDIT: current usage stats, from a 100% charge to 31% battery left.
13h 36m since unplugged
Display 31%
Cell standby 20%
Phone idle 14%
Maps 12%
Android System 7%
Voice calls 4% - Time on is 1m 32s. 70/100 = 0.7. 0.7*4 = 2.8%. 1m 32s = 92s. 2.8/92 = 0.0304... *60 = 1.826
So, 1.826% of the battery is used for each minute of voice calls, which means a full charge would last for around 55 mins of talk time. WTF
EDIT 2: I'm using stock European ROM, XXJF3(?)
Do you guys have power saving enabled on the LCD?
I too experienced similar problems with my battery, a single charge did not last more than 17 hours tops. However, since last charge now I have had it running for almost 48h. So what changed?
- I moved to a better coverage area for 3g, but having only 2g on didn't make a difference.
- I disabled powersaving on the LCD
- I uninstalled the widget "Weather from yr"
- I did a full depletion + charge with the phone OFF
After doing this my battery improved tenfold. While I before when checking "Battery History" in *#*#4636#*#* secret menu I had about 80% Running time. THis is now down to 18%. There was nothing before or now in partial wake, which led me to believe that my phone was actually never quite asleep.
So, try what I did, and see if that fixes your problem, it did that for me!
I'll try it. Yes, i rly have a very old sim card. I think i get a new one when my contract renews on a other carrier. Maybe it helps. Thanks fou your help guys.
1 percent in 10 minutes means absolutely nothing. Does your battery fall from 100 to 0 in 16 hours after doing NOTHING on the phone? (equivalent of 1 percent every 10 minutes.) Try this a few times. Check what's using the battery the most. Remember that with any smartphone on the market right now, the more you use the display, the considerably less battery time you will have; so 16 hours on one charge is completely normal if, say, you have 2 hour display on time throughout the day. it's not realistic to expect any better, and don't believe people who say they can go a full 2 days with moderate/heavy use - this really isn't possible unless you have turned off literally everything, in which case it stops being heavy use.

Last time I was checking I had 34 hrs and 11% used for standby. Then I used GPS with screen on full brightness, had it set to WCDMA only with very bad coverage, was taking images and filming, watching video and surfing. I had no taskkiller or juice defender.
I easily get 48 hrs with a bit more moderate use.

Maybe you could enlighten us what your settings are.
My phone lasts no longer than 16 hours. But I also have Wifi, GPS, Bluetooth and Push Mail enabled most of the time and always 3G enabled (because otherwise I would have no use for a smartphone really).

Well, you have the same phone, they both have the same battery, they are both relatively new. If we put the phones side by side and did the same things on them are you really saying your phone lasts for twice as long as mine? REALLY? I'm sorry but through a day of what I would call "moderate" use, battery is uncomfortably low after at most 24-28 full hours (down to around 5%) and this seems to be the case with not just most galaxy S owners but pretty much every smartphone owner - it's very difficult to get the battery to last longer than 24 hours with "moderate" use.
What's your display use time at the end of those 48 hours you have the phone running for?
Hi everyone. I had NAND installed on my HD2 now for about a month and a half. One of the things that I haven't seen on my phone is better battery life. This is the first phone I have with a data plan so I'm really not sure how much of the battery drains with data. Here is my daily routine. I charge my phone overnight, by 11am-12pm my phone is just about dead. I put it on the charger until about 4pm; usually it's fully charged by then. By the time 10pm comes around it's almost dead again. Doesn't seem like good battery life to me. Someone please let me know if I'm missing something.
Thank you all!
Depends on what you're doing with your hd2.
If you spend a lot of time on the internet with either wifi or 3g, then that drains battery pretty quickly, as with any device. Playing games or watching videos is the same thing, although to a hiigher extent with games. Keeping the phone screen on is also one way to drain battery quickly.
You should install current widget and monitor your standby times, etc. In standy by, your phone should be consuming 4~6 mA ideally.
If you want to monitor your battery usage, first download and install CurrentWidget, enable logging while the phone is on standby to see your standby usage.
Second, need to check battery usage on standby after a call, there are some kernels with a known bug that prevents the phone from going to sleep, consuming 60ma on standby.
Third, Do a battery calibration, it does help a lot if you have never calibrated your battery, android tend to mess up battery reading after a while of not being calibrated. There's a thread about in on forums, search for it, REALLY good info there.
Fourth! check out if you are in a zone with crappy 3G, if the phone has to turn 2g/3g off and on too often it drains battery like whoa.
Fifth, take note of max and min voltage readings with CurrentWidget, your battery might by wearing out (should be maxing at 4.2v and min around 3.3v - 3.6v depending on kernel).
Another thing, before your phone dies, check out battery usage on Settings, see if any program is eating your battery, and check out how long has your screen been on, and post it here
I've always had WAY better battery in Android, even SD, than WMo, MSN/push email killed battery in WMo in about 6 hours, without use, just standby. Android get up to 4 days in standby with Gtalk/Gmail/Exchange Mail, all on Push, along with weather and twitter. With hardcore usage, the battery last between 6 and 7 hours top (Screen on for 4-5 hours), while Gaming, it wont last more than 4 hours (CPU at 100%, Screen always on, GPU at 100%, Brightness 100%).
Normal usage (between 40 mins and 1 hour of Google Maps with GPS on, between 3 and 4 hours of music thru Bluetooth with my car, 10-15 mins talking, about 20-30 SMSs and quite a bit of Gtalk) it makes it thru the day, lasting about 12-14 hours.
Such a low battery life is probably cause your phone is not going to sleep, it should be at 2-5 mah on standby.
Hope it helps
I can play an hour of pokemon (gba rom), listen to pandora whenever im in the car, surf the net for an hour or two, and with a total constant usage of about 5 hours, and at the end of the day ill be left with 30% battery still.
If I don't use it often it will last 40 hours +.
Maybe try a different nand rom?
Im running hyperdroid nand
Zephyrot and kangpeter, Im jealous of your battery life. I'll try what was posted. Thanks for the replies!
