Hi
Mine does about 1 day if I am lucky, WiFi use fries it. This is about what I expected.
The 'time left' meter on the today screen starts at about 4.5 hrs and seems pretty accurate.
If I switch off the auto-off and leave it running with wifi on then it gives me a low batt warning (@ 20%) after about 5 hours. (wifi on, Beams off, backlight off after 30 secs, bluetooth off).

Extended Battery??
Standard battery is 1450mAH. Does anyone know if an extended battery exists?
Nigel
U may want to buy this if u want a really "power" spare battery.. but cost quite high...

Hi,
The battery life depends on how the device is used. In my case, with phone signal strength at full bar and without incoming or outgoing calls and not usage and stationary, the battery will last 48hours on a full charge. With Wifi on the drain on battery is fast, I am getting about the same figure as you have indicated. I also notice that the phone radio draw more power if you are on the move and in some instances I have notice that it draw twice the amount verses staying stationary scenario. The comparison is based on no incoming or outgoing calls.
Hi
Yes, the radio will draw more power if you are on the move. When stationary, the device will tell a base station (BS) that its there, and then there will be no further comms until say 4 hrs time (the time depends on network config), when the BS says 'hey, device X, you still with me?'.
When you are moving, things are very different, the device (MS) will be handed over from BS to BS as you travel. Sometimes there will be 3 base stations serving a given area, the MS will communicate, and return QOS info to the network to decide which base station it should use. This can happen pretty often. A Hand-over occurs when the signal from a new station exceeds the signal from the old station. There is some hysteresis applied to the handover to ensure that it does not swap between 2 or more BS that offer almost identical signal strengths but regular flipping from BS to BS can still occur. There is much more to it than that of course...

Hi
This is listed an an XDA II battery, not a IIs batt. Dont know if there is a difference, I have emailed them to ask if it fits the IIs.
Thanks
Nigel
well my battery lasts for 2 hours full use... and 24 hours standby on flight mode with no bluetooth...
I have the XDA backpack. With this I experience 3 days standby and about 1.5 days on regular (about 30-45 minutes of call, and about 100 SMS messages sent and received combined) use.
Poch
Today was my first day at work since i got my Desire on Sat. So it was the day without regular charging.
Firstly, reception was poor as compared to what i was getting with Touch Pro 2. Same network (Orange), same place, less signal bars and less 3G coverage.
Secondly, unplugged phone 7 o'clock this morning, 100% charged. All day only had time for couple of calls (10-15mins). Used internet (3G when available) for max 20-30mins. Tried couple of games for 15-20 mins and at 7 o'clock at night, the battery was 15%. This is not a heavy use by my standards. Used to do a lot more on Touch Pro2 and battery used to last 2-3days. (I know the capaciy difference btw Desire and TP2 battery but still, Desire should last atleat > 24hours)
Not sure if all these issues are related to Orange ROM/Radio. Will we (on Orange) get OTA firmware update like T-mobile, which has apparently improved their battery life? If not then ...... :-(. Not satisfied with the battery life. Shame it is such a good phone but battery life and signal strength is putting me off.
Whats the fun if you have a "superphone" in your pocket but cannot use it to its full potential due to these two isuues.
Mine was the same,
But after a weeks worth of usage, its now reasonable, IE 18 hours between charges,

I totally agree, there are other posts telling us to turn off or reduce all sorts of settings, its ridiculous that you would have to run any phone at less than its full potential just to compensate for a poor battery.
Sure you could buy a second battery but if that was necessary then they should put two in the box
If you leave gps on then you are asking for trouble, a lesser extent wifi. Having a toggle on off isn't such a hardship though. Poor signal hammers the battery too.
I easily last the working day (7-7) with an hour of music and 2 hours surfing and a smattering of calls and texts.

Come on guys, if you have a laptop, and you turn on bluetooth, wi-fi, play some games etc, it WILL run the battery down faster. It's just common sense. Just because this phone does heaps of things, dosn't mean it will last forever. As phones get more features, they are getting worse battery life - in general. And android is a data centric device, I would get used to it, or simply turn off some synching features if you need to get through more than half a day. Or perhaps get a spare battery etc.
Just out of curiosity did you have your previous phone to constantly sync throughout the day for time, email, google account, marketplace updates, location, weather using gps, 3g, hsdpa, accelerometer etc? Remember some of these connect are activated every 5 mins or so. Will make it worse if you have poor reception. COMMON SENSE PPL!
My issue is that even after the T-Mobile update, last night I charged phone on this time and it would only get to 98% again. Then drop down quickly.
If I charge it off, It seems to be ok (although I will test this again.)
Frustrating.
My battery life is woeful (TMo uk, updated firmware). I've been trying to figure it out using Juice Plotter to record power usage. Basically, whatever I'm doing, if it's on the battery falls off a cliff - I'd say 10% per 30m and my first impression is that it makes little difference whether networking is enabled or not. This makes little sense to me, I've always found in the past that 3G is just about the most power intensive activity on the smartphone, but it's consistent with some experiences I had flashing roms on my Blackstone - some of them would just run the battery down, others would go for ages. One hypothesis is that when a phone is in that kind of "sick" power state, the drain is not really related to which facilities you're using, but something deeper - perhaps the CPU is running full throttle all the time, or something else. I have no idea what's going on right now but I know I have an unusable phone which lasts half the time my Blackstone did with heavier use. I think many others have the same problem and I wonder if there's a bad batch. Bad news if so as we'd have trouble proving it and getting exchanges.
My next step I think will be to hard reset and run it in a very basic mode for a while, maybe some of the apps are causing it.
I'm also finding out that battery life improves dramatically after the 5th 6th charge. When I first got my Desire I could barely make it through the day, after properly charging and letting it discharge all the way to 10-15% now I get 18-20h of battery life with wi-fi on non stop (but with the setting to to turn itself off after 15mins of inactivity).
I was very worried about this when I first got the phone, but now it's starting to be better and better at battery life. I know my demands from a smartphone when I buy it and if a phone get's me through the day I'm OK with that, plus I have chargers at home, in my car, at work, so it's not a problem
I've got one of the very first batch of T-mobile Desires that were shipped on 26th March. It has been updated with the T-mobile 1.15.110.11 patch.
I last charged it on Saturday afternoon. I've only had to start charging it again this morning Tuesday. I've been making a few calls, probably 10-15 minutes total. A few texts. Browsing with G and 3G, maybe a few of hours worth in total. Little bit of Bluetoothing, though that's only a couple of minutes worth. I've had it down the pub a few hours where the T-mobile signal isn't brilliant, so it will have been doing a little "shouting" to find and communicate with the nearest T-mobile mast.
But that means it's lasted a good 66 hours admittedly with fairly moderate use. GPS, Wifi and Bluetooth are turned off unless needed. And it's not regularly Syncing with Facebook, Twitter and all that stuff. The only regular syncing is the weather.
Not sure if these are bugs with some hardware/software or standard functionality with your usages. I'm getting excellent battery life with my usage patterns/settings and far happier with this than with any of my previous devices, since this adds an exorbitant amount of power-draining functionality and flexibility over them too.
- Heaviest use is netting 28-33 hours.
- Typical use is getting minimum 3-3.5 days.
- Light use (also the norm for me me) lasted 5.5-6 days.
- Basic inconsistent call/message/email/net/stocks/news/stop watch/GPS/ compass/notepad/office/weather/ vid/pic/audio throughout the day kept the battery at 84% after 24 hours. 3G off, using WiFi. I don't keep any but the needy apps/settings running BTW.
- Charges to 100% always and stays up there consistently as expected.
However there is a pertinent aspect yet unmentioned;
Biggest difference between my usage and the typical internet crowd is that I don't use or bother with "social networking" (Facebook, MySpace, Twitter, etc) or its likes nor do I play any games on this (hence sync with such apps is off and any updates are set to manual). However rss feeds, e-mail and IMs with close ones I do use during the day when I have spare minutes.

Same situation as mine there.
Sent from my HTC Desire using the XDA mobile application powered by Tapatalk
I'm deffo leaning now that there are faulty batteries out there causing the problem. I can get good life if I can get the battery to charge properly. but when it doesn't battery lasts hardly half a day. I don't use any apps that require automatic updates (all manual or off). But net on drains it very quickly (if I leave data on). Faulty Batteries I feel.
My Desire has a better ability to hang on to a weak signal than my other phones. I am on T-mobile. Battery life is adeqaute, in that, I can get through a day of use before a charge is needed. Will switch-off GPS and see what happens -I never had GPS on all the time on my other Smartphones.
Coming from a G1 that could barely make it through the day on standby this phone seems pretty good.
I got mine last friday it has just come off of it's third charge. I charged it for 3 hours when I got it, ran it right down >10% then left to charge up fully again.
I installed JuiceDefender and bought the UltimateJuice upgrade as soon as I got the phone.
Day 2 (with JuiceDefender) - battery lasted 13h27m, thats with WiFi, phone calls, MMS, 3g, internet browsing/showing it off to mates in the pub and then listening to an album on spotify in the car.
Considering this is a new battery and it still needs several charges before it is working at full capacity, I think that is pretty good for a smart phone! It can only get better, right?
JuiceDefender - I can't recommend this app enough, I don't want to mess about with Task Killers (that don't really save battery), I don't want to stop stuff syncing (because thats the whole point of this phone) but I want to optimize my battery life to get me through the day and this app does it so well!
I've currently got it setup to turn 2g/3g off when in standby but set to turn data back on every 5mins for 30s to allow apps to sync. You can specify a longer interval which will obviously save more battery over the course of a day. The phone connects back to a 2/3g connection so quick when you bring it out of standby so your not waiting around to get back online.
Switch on WiFi at known locations - I have this setup because at home, 3g signal is a bit patchy and it probably uses more battery constantly trying to get a 3g signal all the time, than it does if it is just connected to WiFi.
Turn data off between 2am-8am while I am sleeping.
Turn data off when battery is below 15% - with my G1 it would hit 15% just as I'd be heading home on the train in the evening, so I'd turn data off just so I could send a few texts or so I had just enough battery to make a call. So I figured I might as well use that last 15% battery for basic phone operation and give me enough battery to get home! I probably don't need this with the Desire though.
Any one else using JuiceDefender?

WOW, can I have your battery please ...
What did u do to get this powerhouse. Was it weaker in the begining and got better with charges or was it like this from the begining?
I dont use GPS at all. Only for navigation, when in car and then it is on charge. Normal day.. no gps, no auto data connection - do it manually when internet connecttion is neede. But battery doesn't last a day, merely 12-14 hours. Charged 3 times yet, only 3 days old Desire.
I cant find juice defender in the market?
When I first got my Hero I remember my battery life being terrible, most of it was down to fiddling all the time, however over time my usage changed and the battery had been charged a lot the life was a lot better. Also there were a number of radio upgrades installed, which probably helped.
Since I've got my Desire, the "desire" to fiddle hasn't stopped and I feel as if I'm in the same situation as I was with the Hero.
My opinion is that over time the battery life will be better, as with the Hero.

Yes both Ultimate Juice and Juice Defender are in the Market.
Juice defender was missing for me a couple of hours ago. But actually, when I installed it thinkgs started to go wrong for me. May be a coincidence, or may be a conflict with some other sw.
Following shocking power drain, I have hard reset, and left it with nothing syncing and all networking disabled. As you'd expect, battery level is barely falling in standby. Now to start adding things back in and see what efects it has. First step is to spend 30 mins browsing over 3g, previously this would take out 10% of my battery.

It's not there for me either currently, neither is mybackup pro... :/
Ive been wondering this for a while. Ive always assumed it was a blood thirsty beast ready ravage my soul for every ounce of life and energy within me, but i think thats only because ive only ever kept it on with google maps giving me turn by turn directions. I see almost everybody out there keeps there gps on just about all the time and now with these new kernels and the fact that i carry 2 spare batteries with me, it seems silly to have to keep toggling it off and on everytime i use a location based service.
So, when idle, i.e; not being directly polled by google maps or something of the like, does the GPS really super suck down the battery that bad? If some one can make a comparison of its battery usage to say the 3g or 4g radios i think that would be the best way to gauge it. Thank you all for your help!
GPS doesn't do that much damage to the battery. The GPS will only run when it is requested by a program. I have a golf GPS program (skydroid) and I can play a round of golf with the GPS running 100% of the time and over about 4 hours I will lose about 30-40% of my battery. Now this is also w/ the phone never sleeping and the screen probably on for about an 40-60 minutes.
I am running CM6.0 w/ 7.6CFS w/ Turbo and I have setCPU w/ profiles set up.

i can use my phone for a week. i have this.
offline
backround data OFF
freememoryrecover app each time before i end using my phone i kills all processes.
no wifi or gps or any sort of connection,screen 11% light, when outside or in a car 30% is enough to see.
2.3.3 is good in battery managment. and battery saving mode ON!
i check if i missed any calls twice or once a day and theb back to OFFline mode.
one week can last this phone! screen max at 11% brightness MAX 20 minutes each
day. and itt last 1 week 4-7 days how u use it!

Sage advice if you don't want to get any of the benefits or joy the DHD can bring as a very powerful smartphone.
The alternative is to come to terms with the fact that the DHD has one of the smallest battery (1230mAH) to screen size ratios on the market so if you use it regularly you'll be doing well to last a full day.
eg. Downloading on a mobile network with a comfortable brightness outdoors or under office lighting can easily yield a current of 550mA, ie just over 2 hours constant use. Indoors with lower lighting on Wi-Fi this drops to about 200-250mA so more like 5-6 hours use.
I'm long past trying to squeeze days out of it because I'm much happier using and enjoying it to it's potential and just keep a few cheapy USB cables for charging scattered around home, office and in my car. I also bought a spare battery for less than £10 as a back-up (but have yet to use it due to just keeping my phone plugged-in when I can).
Trust me, you can drive yourself mad obsessing about the battery life when there's so much more you can be doing with the phone. Enjoy it and charge it often.
Just don't leave wifi,bluetooth and mobile data on when you're not using them.
I dont use Wifi, always on 3G, screen brightness to automatic, I listen about 2-3 hours of music, use Whatsapp and Ping alot sometimes make phonecalls/sms messages, surf the web for max 20 minutes, and I get about 1 day and 10 hours. My record once was 2 days and 17 hours xD
SO I have had the SW3 for about 4 days now and the battery life is excellent! Here are my results so far
- Day 2- Took off charger at 7 am, some e-mails, texts, 4 mile (35 minute) run with GPS and Bluetooth on watch, by 9 pm, I had around 45% left
- Day 3 - Off charger at 7 am, some emails, texts, no workout, by 9pm had around 65%
- Day 4 - 7 am off charger, lots of voice interactions, music for 1 hour, 9pm at 59%
Update
- Day 5 Morning: 7 am off charger, noon, with 3 emails, 1 call, 5 texts checked, battery at 86%
- Day 5 Full Day: 7 am off charger, 10pm, 25 emails, 10 texts, 3 calls, battery at 57%
I am sure if you just use it for normal emails, basic usage and not the GPS/Bluetooth music, this will easily go 1.75-2 days. Plus with more tweaks from google, I expect this only to get better
Thanks for your interesting remarks, I'm receiving mine tomorrow
What do you think about the accuracy of the SW3 GPS compared the GPS in your phone?. My Nexus 5 is accurate enough but only when I hold it in my hand... Once I put it in a pocket I get at least 10% more distance in Endomondo due to all the zigzagging.

I just checked my tracks and I have 4 saved runs (3-5miles each). They are pretty spot on GPS wise and as good as my garmin FR620 running watch. The Garmin locks to the sattelites much faster (10-15 seconds), while the sony takes 20-30 seconds. The biggest thing at the moment is the lack of app support...I need something with speed and laps...tracks only has time and distance.
Off at 8am, at 3pm is 86% with regular use. Going to try it overnight and see how long I really can get
It is better than my moto x, so the driving force will be my phone that needs a charge first.
So how did you fare? Or is it still going? I'm interested as I'm on the fence for this watch as well...
24 hour report....
Off charger at 8am, normal usage, (calls, texts, voice), at 24 hour mark it was at 50%. . I did put it on night stand at night (off wrist) , but pretty good to me. I imagine you could easily get 36-40 hours on this until you charge it on the second night after work .
On another test, it seems music drains the battery at around 10% an hour if Bluetooth streaming.
I sleep with the watch and charge it at the same time every day for about 20mins and it's at 50% in average - So seems reasonable to expect 48h of battery.
I sleep and run with it and only throw on charger when in shower and never have had it go below 30% yet. GPS will bring down much faster but quickly charges back up
After a day of heavy usage, showing it off, playing with it, using voice commands and a bit of navigation I had 48% battery after 08:00 to 22:40.
Mine can only last about 14 hours....
Noticed that since a couple of days the battery use increased drastically (wouldn't last 24h now). I just upgraded my Phone firmware - not sure if it's related.
Be carefull if you use watchface like F03 from Smartwatch Bureaux, some have severe bug and drain 10% bat by hour even if you do not use it on watchface on screen but it is installed on your watch.
My watch lost 20%+ over night (7hrs approx) in airplane mode. Anyone else monitored airplane mode loss?
The battery used to last about 2 days, but has recently dropped to less than one day.
what do you mean with "it last 2 days" ? Because at least this watch can last 36-38 hours. If you use it for 12 hour per day,ok, it last "2 days"; but if you are telling me that your sw3 live for 48 hour in a row :silly::silly::silly::silly: i cannot believe it x)
I got 36-44 in a row with normal use

You can see my posts on this thread about this. I have easily had 34+ hours on a charge without issue. I dont use facer and use itellicom watch faces, which do not eat up much battery. It is on always on mode (with ambient). I dont check my watch for the time that much and only for notifications.
I have these items installed
- Keep
- Calculator
- Runkeeper
- Mini maps
- Wear launcher
- Fit
- Audio recording
- Flashlight
- Play Music
I get maybe 10-20 emails a day on the watch, like 5-10 text messages and use it for running with runkeeper and playing music.
