Has anyone noticed that after around 3 weeks of using the HD2 the battery life magicly gets bareable?
After 24 odd hours the batterly life is at 76% were as before it would be on its last legs.
Its made me slightly happier with it now, not having to charge it every second i got.
I recall someone explained before that it's simply becoz one tends to fiddle with the device more when it's newly acquired. Now your battery can last longer probably because you are playing with it less each day.
Or did you do any magic power-saving tweak that you can tell us more about?

Lion and LiPo batteries achieve their max capacity after a period of use similar to the time you have reported.
To keep them there charge as often and for as long as you can.
Exact, it's not your battery lasting longer, it's just you not spending your day playing with the thing anymore.
It's always the same thing, the more a device can do, the more you do with it. On my first 1h train journeys after getting my HD2, I was able to kill 50% battery in 1hr. My first thought was "wow, with my Kaiser I would only use like 15%!!"
But then I took a second thought. I used 50%, but I was browsing the web, in bad reception areas, while listening to music the whole time. With my Kaiser, I'd put music on, check 3 webpages, then put it on the tray with just MSN connected and just pick it up to read/type a message once in a while.
On a next trip, I "forced myself" to do the same with the HD2. Just checked the news for 5 mins, then only listened to music and picked up msn once in a while, plus an unexpected 10min phone call. Guess what? I've only used 20% battery during the trip this time
The "problem" is that browsing with the Kaiser was just painful, so I'd just check the news and put it away. On the HD2 it's so comfortable I forget it and just spend my whole trip browsing heavy pages, which obviously kills battery in no time...
It may be also that battery charge controller incorretly displays battery charge.
It may be that it shows you 75% after 2 days and then by 1 hour your battery will fall down to 1%.
Just starting a thread for battery life experience as people use the phone. Mine is pretty freakin' great right now, but I'll post some initial results after I get home later tonight. I finished charging to 100% almost 2 hours ago, and with just a bit of usage (maybe 10 minutes total screen on time) I still am at 100%. Though, we know that it sometimes takes a long time to drop from 100% to 90%.
What are other people's experiences? Please post display on time in battery stats, as that gives a good feel for how much you're actually using the phone.
Unplugged it at 6:30am with a full charge.
Took it to work, I put it in airplane mode when I'm in the building because I don't get a signal and don't want the radio searching for a signal and wasting power. GPS/Bluetooth/Wifi are all turned off. I turn the radio back on when I'm out of the building, and I'd estimate it's been on 2 hours since it was charged.
Have watched the latest episode of Family Guy and started on the latest episode of Dexter using Rock Player.
I estimate the screen has been on for about 4 hours. I can only estimate because I had to plug the phone in to transfer a file a couple hours ago which reset the stats.
I've downloaded and installed about 20-30 apps today over 3G networks.
At the current time of 3:15pm (8 hours 45 minutes since full charge), I have 30% of the battery left.
I think you're supposed to do a full charge and full discharge so the phone can "calibrate" the battery meter, which I have not done yet, but so far I'm very pleased. Puts my 2 yr old G1's battery life to shame...
Yeah it sounds decent. A bit better than my Nexus One was.
I would say it is on par with the Nexus One. Should get you through the day but you will be plugging it in at night. It is comparable to most android phones.

Without explaining a bunch of boring details, it's definitely better than my N1 so far. Charged it up right after getting it from the UPS guy today for a couple of hours while I took a nap.
We'll just have to wait and see after a few days of use, charges and discharges. Looking great so far, though!
Played around with it at the store today, came in at 3 p.m after school. The demo unit was already at 45% when I got it, surfed the web for about half an hour, downloaded an app, watched YouTube for about 5 minutes and the phone died at about 4:30.
Not really impressed, but its an Android phone. Hopefully it can be better, the good thing is that the web browser is a lot faster than my iPhone 4. That's what keeping me on returning the iPhone, and it starts up a lot faster as well. Took about 20 seconds to boot up after the phone died on me, and the rep charged it.
Definitely will be needing to charge it every night.
3 hr bike ride with music playing used about %50 of the bat. So its way better then my G1 but not as good as my Iphone 2g.
I'm getting much better battery life then I was getting on the G1....love this phone

How about someone download Battery Left widget and tell us what it says.
Will vary by user but it will be more accurate with remaining battery life.
So far the battery life on mine is terrible compared to my nexus one, and that was terrible as well.
I woke up 10am, phone on the charger, took it off, around 2pm made two phone calls. Went to work at 5pm, phone's battery was at 23% around 7pm. My nexus one around that point would be at ~50%. So far I'm not impressed with this phone, more work could have went into it.
I loaded a few webpages... did a video chat with someone on Fring for about a minute (lol), downloaded a few apps, had a few phone calls... one lasting about 10 minutes... and after being off the charger for 5 and a half hours.. i'm at 44 percent power... this is my first android device so I'm not sure if that's good or bad
Have you all that are reporting poor battery life done the full-charge/full-discharge thing to "calibrate" the battery meter. I'm not sure that it really matters, but I'm assuming it does since battery info is one of the things you can wipe in the recovery roms.
I'm still extremely pleased with my battery life.
I got the phone yesterday and played with it right out of the box till it was at 5% battery... i plugged it in lastnight and let it fully charge and i unplugged it at 6:15am this mornining... i used the gps to get to work to see how it was... i have watched videos on youtube, gone on the internet, checked and sent emails and texts, downloaded some apps... and played around with it today... i had it plugged into the computer thru usb for approx 5 min tops to set up some media files... and as of now at 3:33pm my battery is at 50%
Opening mine at 930/10pm, heavily used it to burn it to 0% and did that by 12/1230am. Charged it to 100% by 330am. Played with it a bit then went to bed, left it unplugged. Woke up today and burned it to 0% by 330pm. It's charging right now and we'll see how it goes throughout tonight. It will get a bit of pocket time so I'll get a real feel for the battery life.
Took mine off the charger at 7am throught the day had 20 incoming/outgoing calls all lasted at least 2or 3 mins each, downloaded a couple of apps, checked facebook and twitter a few times. showed it off to some friends and now it is almost 5:00 and still have 60% battery, so I am impressed especially since I had a G1 before this

They aren't changing them long enough. Lithium ion batteries don't have to be trained like the older style ones. Other other culprit could be the batterystats.bin but you can't access or delete that without root. Jut discharge the battery till it powers off and charge for 4-6 hrs.
charged mine last night while tethered to my laptop browsing - took it off about midnight
this morning the alarm sound (pre-alarm 5 minutes, full alarm for 10 mins and never woke me btw), spent about 2 hours+ talking, browsed the web for maybe 15 minutes, downloaded a few apps from the market and ran a few quadrant benchmark test - it's now almost 6:00PM and it's at 40% -
i'm happy with that - and from experience with my MT3G and the vibrant, battery life should improve with some cycling or useage

leave it on the charger for 4-6 hours after its full or just to charge it from empty to full?
I'm very glad to hear about the excellent battery life. A friend of mine has even reported his phone being on for a full day and still having battery life left.
People make sure that you charge up your battery fully before turning the phone on. It's better to be safe than sorry. I know people say it does not matter but otherwise the battery won't be accurate if you just turn it on out of the box.
10 hours and some change later after normal phone usage and I had to charge it... I'm impressed to say the least
G2 Battery Life Thread
Please state if you have a different battery than the 1300mAh it comes with original.
My experience
First day
Received it with 25% ~4pm
Powered off at 0% ~ 6pm
First day (first charge) - wall charge
0 - 100% from 6PM - to 11PM (it took less to charge but i left it a few more hours)
Unplugged at 11PM - played with it till around 1AM
1AM - 7AM - did not charge, it was on standby
7AM - 1:30PM - school / text / web / a few games
1:30 - 2:45PM - a few phone calls / light texting
Battery died at 0% ~ 3:00PM, at around 15-16hours with use, but also no use for about 6hours overnight.
I have installed Advanced Task Killer, whenever I end apps, it ends between 5-15.. average being around 10.. lol
but so far, my first charge from 100%-0%, without overnight use, i got around 15 hours.
drain first or charge first?
nick, you drained your batt before fully charging it.
arent the instructions always telling us how important it is to fully charge it first after you unbox it, before use?
formatting the batt is completely use up all power and then do a full min. 8h charge... best to complete this about 3 times to get full battery capacity
jus use this thing as you want.
this curiosity about battery life...
if the battery is dead, buy a new one. i dont want the phone dominating my life. i use it when and how i want. if battery cant handle it will get replaced.

That was true for NiCd batteries, which are not in use for many years. You don't need to format your battery anymore.
@nickbunyun: now try it without ATK.
Gee, I do so wish there was a G2 forum for all these G2 threads to go in hehe
http://forum.xda-developers.com/forumdisplay.php?f=750
Well, G2 or Desire Z, it's only the first charge... and whether you've fully discharged it or not at first time use, at the first charge batteries aren't at their maximum performance.
See my first charge experience:
HTC HD2: 1st - 10 hours ..... after some charge/discharge: entire day playing on it for the entire morning and texting for the rest of the day (or two days without playing)
Motorola Milestone: 1st - 6 hours ..... after some charge/discharge: same of HD2.
We'll see the battery performance only when you'll use it and you'll charge/discharge it for at least three times!
Anyway, thanks!

I started following this thought process when I got my Motorola Milestone. Sitting it in the dock to charge when not in use and overnight helped but I'm still suffering a little from battery obsession. It's a hard habit to break.
i started it with my htc magic and continued with the desire.
the battery tool it perfectly fine.
at the beginning the battery wouldnt last a day. so i bought a second charger for my work place
so first days i charged it everywhere and after some3-4 days, the battery lasted a full day.
so i started charging over night. no matter how full the battery was.
this works out perfectly well. so i will kepp it.
Does anyone agree that the battery life for Samsung Focus is really short?
I use my phone to check emails, browse websites and listen to music during lunch, dinner and on the road. The total hands on time per day is roughly 2hrs. But if I only charge it overnight, not anytime else, it only last until right after dinner.
It unacceptably short comparing to my ex-phone, HTC Touch Pro2.
Anyone experiencing the same thing?
Who should take care of this issue? Samsung or Microsoft?
My phone on moderate use will last me 1.5-2 days but I usually charge it at the end of the night regardless. In the first couple of days I did notice that the battery would drain pretty fast but seemed to get better after that.
Mine will typically go from 7:30 a.m. to 9:00 p.m. or so while still having the battery indicator having something inside. That's with it being used all day as an mp3 player, triaging email, web surfing, and Twitter.
When you get a new phone the battery has to go through a couple of cycles charging for the phone to calibrate. Also, keep in mind things that drain battery: light theme, streaming, basically downloading massive amounts of data. Make you sure you discharge your battery to about 10% and fully charge your battery a couple of times. Try not to go below 10% not good for battery. Make sure you are using wall adapter ac to charge. Charging from a pc is very slow and generally doesn't fully charge unless you leave it plugged for a LONG time.
Light use I'd say 1.5 days
Moderate 1 full day
Heavy use 7-8 hours
With light use i get about 4 to 5 days, heavy use i get about a day or two. Check to see if you have location services (GPS) running, wifi, etc as the more parasitic things you can turn off the better the battery life of course.
Mine lasts all day for me. A long 16+ hour day with moderate usage leaves me at about 30-35% battery. I keep Wi-Fi turned off and bluetooth always on. Not bad for a smart phone. I've seen phones far worse than this (Sprint Epic anyone?).
My battery last abour 8 - 9 hours, and I'm running for a outlet by then. But I'm a heavy user. Bt headphones with the music playing, twitter constantly, facebook, text, email, IE..., pretty much all of those 8 - 9 hours.
I have just about everything that I can find turned on, and have been using my new toy as much as possible. With that, I'm having to charge about twice a day, which is roughly where I was at with my Tilt2. Your battery drainage really sounds like it's normal, and likely related entirely to how much crap you have turned on and running in the background. The biggest drainer of the battery in any phone is gonna be the radio, so if you want to improve battery life, turn off stuff that connects to the network and set your email/weather/tweets/facebook to refresh much less often. Select "as items arrive" for your hotmail and Gmail so that they push instead of pull. Check your basics first before trying to find a customer service rep to chew out.
I'm happy with my battery life. I just charge it every night like I have every phone Ive owned. I use my phones as my morning alarm clock. I have all location services active, and i activate WiFi when usable. At work I leave it plugged in to stream music and podcast.
Coming from Android and Droid Incredible, the Focus is awesome on battery. I have no problem lasting the full day. I charge my phone each night overnight.
It's a mixed bag for me. the first few days when I was just getting to know it, making calls and just goofing around with basic functionality the battery was lasting very long and things were looking great.
Once I started using the data and other apps, the battery drains very fast IMO. I mean play a 2D game for half an hour and I won’t make it through the day.
Right now I’m not digging it that if I’m out and about I feel like I need to avoid using the phone like I would like to.
I’m really looking forward to being able to do things like being able to easily disable 3g.
I'm most certainly happy with my battery life. After using a nexus one, xperia x10 and the galaxy s I have nothing to complain about with the focus....just lovin wp7 at the moment.

Games are always battery killers, especially on AMOLED screens that tend to get the best battery life with black interfaces, since they actually don't light the pixels up if they're supposed to be black.
Coming from an iPhone 4 i can't complain. Battery on that was amazing. The focus doesn't Last at long but I can't say im disappointed. It's actually better than expected.
It is normal for the battery to die after browsing the internet for about 3-4 hours?? Not happy about that.
Battery life
It depends on how the phone has been used. Screen is the biggest power drain, than the radio (3G data, WiFI, location services).
With all on and moderate usage (gaming for 30 mins, a few calls, and playing with the phone for an hour) I get about 12 -13 hours.
With all off and a few TXT and calls (about 10 -12) I get about 76 hours.
Not bad I guess.
This phone is better than iPhone 3GS.

I agree, I was loosing full battery within half a day with my normal usage for the first 4-6 days... Then after a while, now I can go for 2 days without charging under normal usage...
The battery life on this thing rocks!

I use my Focus heavily for reading texts off of PDFs and browse the internet using WiFi most of the day, and in my free times I listen to music so I use it quite heavily. Yesterday I ran it through my routine day and got about 14-15 hours of full operational time from 100% charge as I took off from my dormitory to university to 0% half-way back to my dorm. My only problem is the length of time it has to be plugged in to charge. Its pretty slow, but that may be because of the large battery capacity to begin with.
the battery life is just OK, hopefully like with other cellphone updates maybe battery life will be improved at least somewhat, we can hope....
I have two of these things. Mine I use a lot and while the battery lasts less than my old 3GS, I am getting used to it and end up keeping hooked up to a charger pretty often.
My wife's on the other hand is baffling. She hardly uses the thing, maybe a call every day or two. For a while there we were getting about 3 days from a charge and then it would still have around 30%-50% left.
Now in the last few days, it drains the battery completely overnight. And I mean completely its totally shut down and dead. That’s with wifi and Bluetooth off and virtually no usage. Not sure what is happening, but this really sucks as now she can’t count on the thing to just be a phone without needing to be babied.
With the newly leaked Dk28 there definitely seems some battery life improvement. I am on 13.5 hrs unplugged as of now and still about 20% battery life left.
I charged it before going to bed yesterday night... left if unplugged whole night.. moderate usage today morning.. emails, browsing, phone calls.
4G service on .. everything else off.
I dont think I saw something like this on Eclair... is 13.5 hrs normal or is it really really good??
What are you experiences? Please share.
I'm at 15 hours right now with 62% remaining, but that doesn't seem out of the ordinary for me. I went a little over 30 hours on one battery a couple days ago, which I think is pretty good considering it's a stock Froyo kernel.
I don't know what your settings are, but I can usually get about 40 hrs on one battery cycle. Most of that 40hrs is downtime, but I can manage about 3-4 hours of display time(games, surfing, etc) and about 30 minutes of talk time.
Your numbers look a lot like mine did before I started killing the DRM service.
Edit: Forgot to mention I am on 2.1 though.
That seems pretty normal. I unplug my phone when I leave for work and plug it in when I go to bed and it's usually at about 40% or so by that time.
For what it's worth, I'm not seeing any difference in my battery life since updating to 2.2. This is pretty much the same as I was getting on 2.1.
I will say that prior to DI18, I was getting about 50 hours on a charge. My last charge before DI18, I had gone almost 72 hours before plugging in to do the update. DI18 killed my battery life, and it's been about the same ever since.

I do have Autostarts killing DRM at boot. Not sure that it makes a difference on Froyo though.
I was on di18 from the day i bought my phone and i never got thru the day without plugging in at work.. i plug it in at night..pick it up100% charged while going to work and by about 2-3 with moderate usage it wud be around 25% left and definitely die if i dont charge at work on the way back home.. which is something i m not seeing now.
Are all you guys using this drmservice.. i wud like to kill it too .. not sure what it does tho.. will do a bit of reading..
I usually only have to swap batteries once a day. I leave wifi on nearly all the time. Bluetooth and gps are usually on for about an hour a day. I listen to music with the phone during work and when I go for a walk in the evenings. I play some games and browse the web here and there, too.
Last night, I swapped batteries before bed, and lost 11% in 9 hours, with wifi on. If I'm constantly doing things with my phone (gps navigation, games, etc) then I can kill it in 6 hours or so.

Is this with the regular 1500mAh battery ?
For people getting 13 hrs+, or anyone really, what does your spare parts network usage look like? I'll update this post with mine.
I've been all over the place with battery drainage. (I've calibrated since new kernel). all details equal (same app setup, traveling to the same place, etc), sometimes I drain 15% per hr, sometimes 5%.
sent from my RAZR
I read some of the comments and had to go back to top to see if I was in right thread!!
My 2.1 rooted used 2% an hour, I'm a moderate user, but most usage is data on 3g. I would have 50 plus left at bedtime.
Went to DK28 - idle used 6%, had to charge my late afternoon with any usage. Same setup, actually less programs.
So I rolled back, this was the same as pre Sept 30 upgrade and yes, I was toggling, killing, stopping, everything the same.
Just this morning, I took it off charge, spent about 10 minutes going through facebook and seesmic, check the charge percentage and I was at 93%.
What the HECK are you folks doing to get 18 hours of heavy browsing on WiFi?!
I really don't want a phone that has a tough time making it past lunch with it mostly sitting inactive. Heck, my ancient G1 did much better than this. Just checking now, I unplugged it at 6:30, and I'm at 89% already. Although I will say that from about 6:30 - 7:42 I've gone down 4%, so I suppose that's not too terrible. I'd love to have 2%/hr.
Addl data:
From 7:42 - 9:34 with it just sitting on my desk, it's down to 81%, so it's still losing 4%/hr without being touched.
