MESSAGE to HTC, Tmobile, Android and Google

There is a problem with our battery life and we all know its true... I have even been given a new battery and HTC mains charger
I turn off any service im not using at the time (ie: wifi, BT, GPS, NETGPS,etc) not that I should have to do this, but lets story on track...
My battery will make about 1 day as I am A "power user" but if its not plugged in I wont have the juice for my alarm to wake me up, my wifes Sony Ericsson lasts 4-5 days per charge, but lets not compare apples and oranges, the whi-phone 3g my sister has sahe bought it about the same times as my g1, she hadn't ever heard of "deep cycling" 2-5 times when you get a new phone, she never lets it discharge fully and just tops off all the time, AFAIK she is treating a NIMH cell exactly the wrong way, BUT SHE GETS 1-3 DAYS depending on the type of use, and never turns off ANY of the 3g, gps, net gps, wifi, BT nada and Id say she uses hers alot because its her primary camera, GPS & A/V player
my question is WHY?
Im sure there must be somebody involved with the development of this phone/OS that reads thru here, since there is more exciting stuff coming from XDA than there is the market...
Im gonna add a poll that pertains to battery use...
I wanted to add one very negative one but hit submit not preview, maybe just post and dont vote if none apply..
they better come off a new battery almost all other new phones will get 1-2 day + average use, Ive had phones that could go 3-4. but the state of the art G1 mindblowing innovative phone wont even work a whole day, so what if its bigger than the whi-phone, it has no keyboard.
I for one would like to hear some solid info on a replacement battery and back, for new and existing G1 users, early adopters got the fuzzy end of the lollipop on the HTC->headphone jack adapter I got the headphones with the htc angled adapter from fleabay, so many manufactures stick it to the early adopter, when we are the ones that get the word of mouth going, as people go "WOW that thing is cool!,what is it?! they know when we bought out phones and should be able to figure out when the head phone rev change was made, so send them to the first of the buyers....
IF the battery issue isnt fixed, alot of people will be very angry and the g1 will flop.
I think the bad press is starting to out weigh the good press the G1 and possibly android as a whole is at a crossroad. If the g1 tanks Android will be stained forever...thankfully enuff I dont think XDA-DEV would give up on this badboy, I love this thing, and I love it for what it can be

Well stated sir.

HTC/Google need to fix battery problems in G1. Maybe it's soft bug, but maybe it's a hardware bug - Nobody knows

I dunno. With normal use, I get about 12 hours or more from my stock battery. That's about the same as other HTC phones I've had.

there is a battery issue and we are al aware of it.
i have managed to have it last through out the day
just set the brightness to the lowest possible, sleep time to 15 secs
turn off data and wifi and anything else that you are not using
its not how the phone was intended to be used, but it's what i ave to do for now

I find it fine for everyday use. Of course I haven't done a full test but maybe tomorrow I will.

I would like to use my G1 like I use my WinMo but no way I can with the battery.

I think you're exaggerating here a little bit. The battery life, while it got press at first, has faded from the limelight of android news for the general population. The G1 is already far from a flop and I don’t think there’s going to be a sudden mass return of all the handsets sold.
Let’s face it living on the cutting edge means you will get cut sometimes. Your high expectations will not always be met and manufacturers will frequently not care. The battery life is less than what many people expected, but we’ve learned to deal with it. At least we have options (power management, backup batteries, and expanded capacity batteries), but I’d not hold my breath on HTC making any major moves. How long has the issue been going with the TYTN II drivers anyway?

I have no idea what kind of use gets 1-3 days, but it certainly isn't 3G web browsing. Most iPhone 3G battery life tests clock 3G data use at about 3-5 hours. Based on my own usage of a friend's iPhone 3G, that seems to be about right. Coincidentally my G1 gets about 3-5 hours of 3G data use as well.
Frankly, from an engineer's point of view I have not seen any power drain tests conducted with enough rigor and variable control to be worthy of being called a truly scientific analysis. Even the best "battery life tests" out there aren't declaring what type of testing environment (los and distance to closest 3G tower), what background apps are installed, ambient temperature (which affects the battery discharge profile), etc. Without considering and removing these variables from the test, deviation could be as high as... well there's no fixing the percentage really. It's all just junk data.

I do notice after I installed Task Manager, to close out programs I am not using my battery life went up. There are a lot of un needed start up apps.

Yep my friend has iphone and we did test last weekend, both went 3 hours and change then died. If i dont use internet and set timeout and brightness down plus use task manager mine will go as long as my dash. I personally dont care about the battery life, i have a computer, home charger and car charger and i drive for a living so if it gets low no biggie. In my opinion i dont see android going anywhere and i love the g1. Just like wm its gonna take time to get off the ground. To say its at a crossroads is ridiculous.

I am using ADP1.1 and yea if I am browsing the net with 3G for 3-5 hours straight I start seeing the battery go down. But from 100% to 0% takes me longer than 5 hours. I know because I like to lay in bed and don't care to come check my messages LOL

I bought a G1 last week and so far I have been really dissapointed. After having an elf and seeing other htc phones I was expecting big things from the G1.
I am now a week into ownership and after 5 full charge - discharge cycles I am managing to get 24 hours out of the phone with next to no use what so ever. If i check my emails and do 30 mins browsing the phone is dead in 6 or less.
The hardware is simply put 'very poor' my screen is wobbly and the back is loose, all this after just a week.
As for android, it is fantastic everything I expected (except hotmail support) and there is no way it is going to flop. Its just a shame that google and htc didn't wait until they had the right phone for the job.
Thats just my 10p worth!!

It all depends on what you have installed. for me the start up is. I beleve amazon does too, but I uninstalled that. But the first thing I do is go into task manager and kill everything. And only like two things auto start up. I really with HTC built in a x-button app for android. I loved the click x for close.
myFaves
messaging
voice dialer
calendar
Alarm clock
k-9
woot checker
tunewiki

Under light usage I get about 36 hours from full charge to shutdown. That's GPS on, Bluetooth on, Autosync on, periodically doing e-mail and web browsing.
Under heavy usage (Which is basically I listened to MP3s for 2 hours) it goes at least 17 hours before I plug it back in. I haven't tested but I'd bet it could go 20 or more.
That's as good as (or better) than I was getting on the Wizard/MDA.

I dunno if anyone has stated it but the problem with the battery has to do with the phone recieving the cell signal. For some reason the phone runs in overload when searching for a cell signal...I noticed this one day when T-Mo suspended my service and my battery meter never moved all day, I think by night it was down to 85-90%...sure enough that night when I paid my bill and the phone started picking up signal again, the battery depleted at "normal" speed.

Why do i keep hearing that there is no hotmail support? Android (and G1) works with hotmail just fine! Just go to the Email program and set it up. WHY!! .. I am having connection errors sometimes though..
Battery is a big issue. Never had any luck with it.. EVER.. just unplugged it and after about 1+ hour it's down to 66%. Played a game (slide puzzle) watched 2 youtube vids of about 3 minutes each. And I had it fully drained and recharged a couple of times in the beginning. It didn't even took 10 minutes to drop from 100% to 89%.. But I was on wifi.. Maybe this is normal.
Software has a lot to do with this I think. Yesterday I had about 50-60% left. Did something, can't remember what, opening programs or music. And closed it. After 5 minutes I checked and battery was hot and had drained to orange level. I checked with task manager and only calendar/messaging/tunewiki/music was on. I closed all and restarted the phone, cuz it was still hot. Luckily it lasted a few hours till I got home, with very carefull use..

HTC response on short Battery Life: Expect it!

I wrote to HTC to ask how they measured their "up to 490 hours on Standby" and "up to 380 mins talk time" referred to in their HD2 website specification especially as people like myself were experiencing the battery going flat in <24 hours with almost zero usage of the phone.
Here's their official reply.
Thank you for your email. The specifications that you have referenced are laboratory test conditions, and are not indicative of real-world performance, nor do they take into account the considerable drain incurred by the myriad services and programs that run as a matter of course on Windows Mobile 6.5, as well as any other background applications that may be running, which may not be readily apparent. Please be advised that these laboratory test figures are in line with EU regulations concerning the testing of mobile device batteries, and the real-world battery time that you have quoted of 20-24 hours is well within what we would expect of this device. We have recently released a large capacity battery for use with the HD2, and this can be purchased from the following link :- http://www.htcaccessorystore.com/uk/p_htc_item.aspx?i=195058
So in simple terms, we mislead you in our advertising and you'll be lucky to get the battery to last 24 hours. We can't fix it so buy a bigger battery!
What's the point in publishing performance data that has no relationship to "real-world" conditions. Most customers won't be using the phone in a laboratory.
Perhaps we should start a new campaign to get HTC to be more honest about "real-world" expectations.

Because as they said that measurement procedure is a standard that everybody follows, so it would be stupid to do it differently, why "not lie" when everybody does so (and they actually probably wouldn't be allowed to do it differently).

What can i say........except that HTC should look in to the real world more often!

I use many phones, from htc, and from other company , my last two nokia phones was "business versions" with "everlasting" battery - first e65 least 40h , second - better version - only 22h ( e66) - it's normal - in this world

If HTC say it's a standard EU process, then perhaps we should campaign to get the EU standard changed as the current published figures give no indication of the phones real performance.
Don't get me wrong, I love the phone but I've never seen one like this go flat in such a short time when on standby.

i love how they say it lasts up to 490 hours on standby, but 24 hours is what they would expect
it's actually ridiculous how deceitful these companies are, we deserve better than this
it's not right that they lie right to our faces to what we are getting and how we have no rights
just not right.

I think we need a bit of a reality check here. I'm not especially inclined to defend HTC but they have a point about the stuff that may be running on the phone. Anyone who has tried some new toys must have encountered one that sucks the life out of the battery for no obvious reason - scale that down and extrapolate across a raft of apps that most of us here will have on our phones and you will get a host of variations in terms of battery life...which is exactly what we do get.
Secondly, as kilrah said, that's the way battery life is measured. Instead of whining about it we should treat it as a relative indicator against other phones because that's about all it is good for. I suspect most say 'up to...' in small letters in front of their stand by and talk times anyway.
If I were to buy a car because the specs say that it does 40 miles to the gallon I'd be a mug to expect it to do that when I'm thrashing down the motorway towing a trailer with the windows and sun roof open. But I might well buy it in preference to a car that claims 30 mpg because in the long run it will probably cost me less in running costs.
You pays your money and you takes your choice...I don't personally see any significant misrepresentation in this, but there may be a little end user misunderstanding?

No surprise here. I observed the same discrepancy on all my phones till now - Motorola, Nokia, Samsung, Siemens, Ericsson, Sony Ericsson, HTC.
Actually I use my phone a lot and I'm more than happy with its performance so far - huge and bright screen, powerful CPU... What are your expectations? 48 hours? A week?
If you think, this is something impressive, go and buy yourself a new monitor and then just measure the advertised contrast ratio - 10000:1 ? Seriously? In fact it is only 700:1. Nothing more to say.
Watch Out: Crazy Contrast Ratios

Exact. And especially on smartphones it's absolutely impossible for the manufacturer or a standards organisation to imagine how you will use your device.
If they can quote anything, it's stock configuration, open the box, put sim card in, press power on, enter your pin, put phone in standby, leave it there, note how long it lasts. That's all.
Knowing that you can do so many things on it, install so many programs that can do what they want to the phone, and that depending on usage the battery life can vary anywhere between 2 hours and 4 days it's totally impossible, by whatever means, to quote something realistic.

When you buy a WM device (or any other Lith-Ion device for that matter) you should know what to expect with regards to battery life, it's not rocket science.
Lithium-Ion batteries are poor, until battery technology is improved it's what we should have come to expect.

That's a bit simplistic, knowing that firstly there's nothing better yet, and secondly the good old phones we had that were lasting a whole week were also using the same batteries or even worse NiMH ones.
It's a combination of a lot of things.

battery life
I turned htc sense off on my phone and now the battery lasts 2-2.5 days with what i would deem reasonable use ie using the internet checking emails texting and 4 or 5 calls a day , if i turn sense back on the battery life drops to about 15 hours so i can live without sense !!! Im far more concerned about the speaker problems and pink photos than the battery )

I assume you are replying to me?
After having 4 HTC devices, I didn't expect anything more from the HD2 than I got from the Wizard or my Kaiser or my Diamond, if anything it was obviously going to be poorer due to the huge screen, hardware and all the software I knew I would be using.

I think your best chance of getting their claimed hours would be by:
1. Completely charging the battery;
2. Use a bare-bone ROM with absolutely nothing installed
3. Switching off all radio signals.. (that is, put the phone in flight mode so that the phone is not transmitting like wireless, bluetooth or anything else at all...)
4. leaving the phone on standby with the screen off.
Of course, noone uses their phone like that, but HTC have used the term "up to" to protect themselves...
HTC would be stupid to change the way they rate their times since every other company is using the same method. I doubt anyone would want to buy a phone that says "Standby Up to 24hours" when every other phone has "Standby Up to 500hours" At best, the rated hours could be used as a comparison/indicator against other phones.

I'm celebrating two weeks into life with my HD2, and after suffering water damage with my HD which had no effect except to bring battery life down to 8 hours a day, I'm really pleased with my 24-28 hours of battery life.
On days I'm using it a lot, I expect 15 hours. However the other day I barely touched the phone (no calls, no music, no random turning on the screen) and I was on 65% after 24 hours, which I felt was good.
I agree with the OP, their quotes are a joke, but I don't look at specs, I look at reviewers to tell me "I expect a day's life from this phone" etc. when I choose a phone. With a screen this size I don't expect miracles, but again, it does feel like a blatant lie when they suggest the phone can sit for weeks without dying, and i give manufacturers (including HTC) no credit for being economical with the truth to their customers.

My SEX1 used to last a few hours more, having a smaller screen, larger battery, and less than half the processor. They specced same timings, as I said I got a few hours more. I doubt Iphone or any other manufacturer, will spec their device like, Standby time 24hrs, talk time 4 hrs. Who would buy such a device?
Anyway I didn't expect it to last any longer. Good thing is I'm in front of my pc for long hours, no harm in letting the phone plugged in.

Isn't draining the Li-Ion actually shortens the battery life?
I'm told that letting the battery get lower than 2.3v isn't a good thing.
Let the battery get low, but not low enough for auto-shutdown

It's called Business Opportunity
All companies all over the world is like HTC.
Whenever there is a problem, they will direct you to purchase something to "solve" the problem.
HD2 problem that we are facing is poor battery performance (if you enable non-Sense). "Solution" is to buy bigger capacity battery.
Problem : screen easily crack
HTC "solution" : tampered glass screen (if HTC would advertise...)
Problem : Screen too sensitive
HTC "solution" : special screen protector (if HTC would advertise...)
Problem : this, that, this , that,
HTC "solution" : you pay, we gain profit!
That's the real world scenario....
Conclusion : HTC = poor quality product(s) at expensive price.

Sensible solution: if you want battery life of more than 1-2 days, do not get a smartphone, especially not one that has the fastest processor on the market and a 4.3" screen. And read reviews that will tell you "you'll get 1-2 days" and "it lasts just a bit more than an iphone". I.e. Educate yourself.

Solution to DHD battery problems. Contact HTC!

Hey guys! I'm a new user on this forum and I also a completely new android user, I have just gotten the HTC Desire HD. And I'm really really enjoying the OS. The way you can customize the OS is amazing! And Therefore I feel like I have been missing out for a while.
However there is one single problem about the HTC Desire HD and sadly it's a pretty big problem. (You guessed it,) the battery life. I'm not gonna lie, if i cut some features i can easily get through a whole day. But whats the point of buying a phone with lot's of features if you can't use them, and whats the point of having a 4.3" screen if you can't have the brightness level at 50+.
To the point!
HTC have already made updated batteries that have a much higher capacity than the original batteries, these are for some of their other products.
(just look at the higher capacity HD2 batteries by HTC, they have a higher capacity than the original HD2 batteries.)
That's why i suggest that we all contact HTC and let them know that we are both aware and annoyed by the horrible battery. And then request a better and improved battery for the Desire HD.
If you look at their updates, they have a pretty good history of listening to their customers.
And if their customer service department get about 300 requests in one single day I am absolutely sure that we will see a result in a month or maybe even faster.
I live in Denmark myself and I've seen a similar thread in
a Danish forum and in two days time we have had 183 people send mails to the Scandinavian HTC customer service.
Now there is only about 2000 active users on that forum so that's pretty good for two days. And with such a huge success in a Danish forum, I'm sure a big forum like this would do even better!
So if you have the time to write a little email to the HTC customer service telling them about the poor battery life and then make a request for a better battery, I (and probably every DHD user) would appreciate it.
And even if you are one of those lucky users that can go for days without charging while having standard settings,helping us wouldn't hurt.
Thanks in Advance

Well....although I do get your point, I am not sure that I, and probably other people as well, agree entirely on the 'horrible' battery life.
Yes, at first, it does look to have poor capacity when you get your DHD out of the box.
But remember, a lot of people, if not allm are using their new toy a lot the first couple of days.
If you browse this forum and the DHD topics you'll see that people report a lot better battery life after a couple of charges.
In addition to this, when you get into rooting and flashing, you'll see that users with custom roms, custom kernels and special profiles setup in Setcpu (like less Mhz usage when the screen is off) actually even get better battery life out if their DHD....
In essence, from what I have read, most people are able to use their DHD for one day without charging, which in my opinion, is quite acceptable, considering the size of the screen, the speed of the device and the possibilities and syncing going on....
If I sometimes read other cells'threads, it appears to me that the battery life on the DHD is not that far off, or even is better, than other top devices....
Having said that.....the effort you take I understand for sure, I just am not sure that HTC will do anything about it (as I think what we get is what we should expect)...

Where is the solution in that? Infact there is no solution its how it is

DHD battery life sucks.
There is no point defending it. Its a bloody mobile phone, it supposed to be able to work out of box, not a science project that u have to spend days tweaking it in order to last a day without the bloody adapter!

It does work out of the box. Did yours not turn on?
If you mean 'it's supposed to have the best possible life the first time I fully charge it on day one' then, no it's not. You are wrong.

I just don't get it this was my first proper Android phone after coming from a HD2 and an iPhone 4 and the battery life is on par with both out of the box however simply reducing the time some apps sync I mean can you really not wait the 2 sec ish Twitter etc take to update? Really does improve battery life I have my screen set to 30% brightness which is more than enough if not you need specsavers not a new battery.
At a push I can get 2 days out of my DHD and I would say I'm a average to heavy user about 30 min calls 50 odd text and a couple of hours playing games surfing the net
Gadget show last night drained an iPhone 4 from full charge to flat in 2 hours using the layer app
I don't use setcpu etc I've just used some common sense.

I use iphone4 along side my DHD, almost identical setup in terms of sync and updates. when my DHD battery flat out in the afternoon, iphone4 has typically over 80% left.
I dont think it takes a rocket scientist to see DHD's battery is an issue.

Unplug mine from charging about midnight, get home from work between 18.30 and 20.30 and most nights I have approx 30-40% battery left, LiOn batteries need multiple charge / discharge cycles to get the best out of them so no phone is gonna be at it's best outta the box.

There seems to be massive difference in peoples experience with there DHD mine defo lasts as long as the iPhone 4 I had how yours can last less than 20% there must be something wrong

mine actually died last night (the first night i had it) i was a little surprised but i checked the battery usage and com.zxing..... used like 70%
lol it seems the barcode scanner didn't close and kept the camera on all night

I am a heavy user Facebook sync every hour a hundred odd texts a day few hours of internet browsing and I can get more than 12 hours mainly like 15 hours unplug at 7.30am and charge it 12.30am

it seems that some people have a very good battery life even with heavy use,and some don't. I am new to android having come from windows mobile. In winmo devices,the radio version on the device can make a difference to the battery life on similiar devices.maybe this is the same case on DHD because I noticed there are several version of stock roms with different built of radio image.

There isn't really a benchmark for "heavy user". I reckon its largely due to different interpretations. Throw the difference in batteries that are likely to exist due to the manufacturing process, and you'd get varying reported results.

why do people complaint so much about battery life of DHD and other smartphone. when you look at their capabilities, you wouldn't switch your laptop on an expect it to last all day. cause its a smartphone doesn't mean it can do everything for you!
if the battery really bad, then the is a fault i.e faulty battery,app which is eating up resources, radio constantly changing from 2g to 3g which i think one of the biggest drain on battery or a set up which just going to drain battery faster etc etc. These phone when "out of the box" are set up to show the phone off, so yes its going to have it all sing and dancing at you! with everything switched on why you taylor the setting to meet your needs. please don't come back and say "but yes why have i got a smartphone and then i have to switch off all these features" you don't but don't expect it to last all day.
sorry about the rant but i think some people just have unrealistic expectations how long a smartphone can last. people who complain that the phone cant last 24hrs, why would you want it to last that long?. you telling me you don't sleep in that period of time if you want a phone to last 2 days get a nokia 8950! an if your a person who uses it as a business phone, come on what do you expect? your a heavy user. use some sense, have it so you can charge on the go or a get a nokia 8950 as your business phone, an use your smartphone as your own phone.

True, but i honestly cant see why it would hurt to encourage HTC to make a new battery with higher capacity as a part of their accessory lineup for the Desire HD.

sorry yeah i do agree with you, that HTC sould bring out a higher capactiy battery and don't understand why HTC have not used a higher capactiy battery in first place. ive also have a X10(1500mAh) and BB storm2(1400mAh) both have higher capactiy, and X10 is the worst for battery life out of the 3 phones and DHD beats both these phone on battery life.
HTC have the reasons why they used that size battery for the DHD and if they do bring out a higher capactiy at least you can believe the claims of it being a 1800mAh, were these 3rd party batteries claim 1800mAh but really you only getting 1400mAh.
i was not aiming this rant at you, an im sorry, its to people that complain about battery life of todays smartphone and there expections of them.

Test it! You must not use more Power per Hour than 1%.If you are at 4% you do something wrong. In standby of course...

HD2 Extended THIN battery...last long!!!

Just want to inform those who are frustrated just like me about the battery draining problem with the limited hd2 stock battery. On average and moderate use with most roms it will die between 5 to 6 hours or even earlier no matter what setting you have. If you use the extended battery it will double up you battery power. However most extended batteries are ugly fat and requires a custom battery cover for which you have to sacrifice the many/all phone cases you would like to have on to protect you phone.
I have found this THIN and EXTENDED battery at ebay:
New 2300mAh High Capacity Battery For HTC HD2 T8585 LEO
Item number: 260840063860
I want to confirm that after several and full charging, it lasts me about 12-15 hours, and I am not kidding. You don't need to sacrifice your case or don't need an ugly fat battery cover since it is the same size of the original battery. Please note that there are few 2300 mah extended and thin battery of HD2 available on ebay. I tried couple of those and they both last well over 12 hours. If any of you are interested, you may want to consider. Hope this solves your battery drainage. It solved mine. Good Luck

smells very, very fishy
I don't know of ANY batteries that will pack 2300mAh in standard size battery.
Also check: http://batteryboss.org/ for any more info regarding 'false' capacity claims
Btw. read carefully in auction "capacity UP TO 2300mAh" lol, might be 1200 as well

12hrs is about what you get on a standard cell.
6hrs is what you get on a ****e rom/kernal or with a cheap china battery swollen like a rotton mellon.
2300mAh in a standard size battery is impossible using current Lithuim Ion technology.
Total bull**** & that linked battery will be 1100 maybe 1200 at best.
I have dealt with factories in China making this junk & as an engineer can 100% claim 2300mAh in standard size cell on Li Ion is not possible ...

With only 5 posts we have to be sceptical you are not selling your own cheap Chinese imitations?
In the past I have tested plenty of these cheap batteries on eBay. All of them are junk. You must be a very lucky person to find one that actually lasts longer... lol
Look at it this way do you really think cheap Chinese companies on the backstreet corner has the same resources as the mega corporations who would love nothing more than make their phones thinner/smaller and have better battery life?
Common sense.

Not only that, but technology used is already at limit(max power at certain density)

Take into consideration that Motorola atrix 4g has 1930 mAh and it is thin. So it is not impossible! I am not an engineer for that matter but the battery I got certainly doubled up the power...as I write my last charge was at 8:30am...now it is 6pm..I have 50% left after one hour of music, half an hour of navigation, few short phone calls, an hour of web browsing...checking facebook few times, few test messaging....two hours underground without service when the phone really drains out battery like diarrhea looking for service....my original battery would be dead by 3pm the latest....I have 50% left!!! And as I was saying Atrix has a thin battery so it is not impossible!!! OR I must have pure luck
AND another thing, I am not a seller!!!!!!

I am not a seller by any means.....just trying to help and thats all. I have owned three HD2 and still do... I have tested all most every single rom here and tried many different batteries before I actually found one that last me very long time than the original battery with same cpu settings and rom. Just sharing what I found
P.S. Most of the resources of your mega corporations are actually in china...it is called outsourcing lollll....check the labels of your products buddy

Mister B,
Do you think there is a manufacturer out there who can actually produce a new extended battery for our HD2 using new technology (like Huawei Honor's 1900+mah)? If only there is a DIY battery...

I am not an engineer and if you really are then I can tell you this... there is nothing impossible in tech world...and there is no limit. Many of the technology, hardware and software you see today, someone in the past thought are impossible. Making things possible is what we call science. I am not totally discounting the limit. But making an extended and effective thin battery is not impossible when everything getting thinner and lighter day by day...just like making a pocket size cell or smartphone in the era of brick-sized and shaped cell phone was considered impossible. Science and technology do not take things for granted...

I get 24 hours from my battery, with 3g on and bluetooth on, 1 hour of calls, some texts,2 hours of 3g browsing (lots of them reading xda), reading documents and a lot of emails..
So I think you had a bad battery and or you have wrong settings or you havea very intense and heavy usage..
With a cheap Chinese extended battery from ebay for 10 € I can easily get 48 hours..

I own this battery. It provides very similar performance to the stock battery. In addition, it was a bit too large for my HD2; I had to trim it to fit with an Exacto knife. I have the TMOUS model. It may be a little better, but not much.

For 10>15 bucks it is impossible.
No cell manufacturer makes a cell of 2300mAh as small as HD2 standard battery.
Latest 1800 to 1900mAh batteries are thin but overall volume is larger & cells are constructed with absolute minimal framing & wrapping.
China has some great manufacturing but it also has world leading fraudulent copying & low quality goods with misleading specifications masked as high quality items.
Cell technology for small 2000mAh+ batteries will come but it is not available yet & certainly not first on eBay ...

Huawei Honor is a 3.7v Li-Polymer cell, the cell itself is quite large & test results seem power is around 1850mAh & up.
Li-polymer has lower power density than Li-ion & lower charge cyle count but it does allow very thin cell designs & minimal battery shell/wrapper & more form design options.
Li-Polymer is not new technology, Good progress is being made on improving power density of cells but it will be 2 to 5 years before you see big gain in retail products & it won't be on eBay first ;-)

it is kinda tight...mine lasts at time and half the original. Never have to worry about it dying if I don't have access to charger as I write this it has been off charger for 10 hrs and about 60% juice left. Lot of credit goes to the great Rom and kernel developers of this great site. I salute them!

It is funny that most replies are attacking China. China's manufacturing ability is real and well tested. That is why you will barely find any small or big corporation who does not rely on China. Now don't start calling me Chinese...lollll I am neither Chinese nor a seller!!!

The Chinese put out some quality material, including batteries. I think almost all of mine have been assembled there, although some will mention "Japanese cells".

Wow 24hr that's awesome. On HD2? If you don't mind which Rom?

US Brentronics buy cells from China for military use, unfortunately copy products & cheap tat for quick profit has damaged Chinas product reputation as a whole ...
The 2 largest cell suppliers are Japan & Korea but all the low cost Chinese batteries use Chinese made cells some of which are ok & some not as QC is low & production material grades vary drastically.China has amazing manufacturing abilities but also some amazing waste of human resources & materials to produce pollution & junk products with a life-span of maybe a week !
When buying from China do some product research first ...

I have a almost 2 year old T-mobile HD2 and I can tell you that my standard battery will easily last me 12 hours when I use my phone to listen to MP3 or FM radio. Normal use for me will easily net 2 days with standard outlook settings, yahoo settings, and a few phone calls along with text mesages.
1 standard battery will give me about 4 hours of video before it croaks... and that is with bitrates upto and including 2mbps.....

The problem is not with the Chinese ability to manufacture quality items, it is with their preferred route of as cheap as possible with no to little quality. They have chosen to be the kings of disposable merchandise.....
My HD2 was made in China and that phone has been nothing short of spectacular......

Thoughts... Phone (not Rom) with best Battery life!!

My bosses are due for an upgrade and i have been reading everything under the sun about which smartphone has the best battery life... problem is, every website has different results if any on battery life. I realize that big screens and quad-core are all the buzz, but the HTC inspire that one of my bosses has, is a battery hog. We have tried everything to get more life out of the phone, new batteries, multiple batteries and nothing seems to help. The one with the HTC is a power user. Texting and calling around the clock. I would like to get him another HTC with the same screen size because he is used to it. Any ideas/websites would be appreciated. I have read too many reviews and battery life seems to be an afterthought with most reviewers. I like to see test results and comparasions on battery life but so far i have not seen any good ones.
thanks in advance!

I'd recommend looking for a phone where and extended battery is an option - or having multiple batteries to switch in and out (or, following that, multiple extended batteries to switch in and out).
I don't think any phone out there really has abnormally good battery life - if you're a power user you need to find another solution like an extended battery or power pack or something.
I've gone with multiple stock-size batteries for myself. I feel like it's reasonable for the device to not last all day - there's a lot to power there so I don't mind the one minute or so that it takes to exchange for a fresh battery - and the spent one can charge while the next one is being used so that you don't even need to plug the phone itself into a wall.

The Samsung Galaxy Note II has been getting very good feedback from a battery life standpoint.

Looking for a phone that has a battery that has the biggest Ah spec is a good starting point. Also, most android phone reviews include a battery test, but you should only compare reviews of different phones on the same site, as each site probably uses a different testing method to see how long the battery lasts. I don't know if there are any phones that have a lithium-polymer battery instead of a lithium-ion, but li-po batteries have higher energy densities (that should reflect itself in the Ah spec).

GSMArena has set up their own standard for testing battery life. For the average they include 1h of calling, browsing and video playback (all separate and the rest of the time is on standby) if I remember correctly, that way they get fair testing conditions for different phones (some are better for browsing, some for calling, diffrent platforms etc). They also include battery life for browsing, video and some other activities seperately. To me their tests are quite nicely standardized and thought through.
Searching from the biggest capacities is also a great idea, GSMArena has a new search field, which lets you to search according to battery capacity.
I'm not totally sure if they have a certain page for maintaining their battery test or if they have them somewhere on the phones info page, but I would start looking for them through the search or from the blog part of their webpage!
Best of luck!

Thanks for the replies i appreciate them.
I will check out GSMArena

No problem. Glad I could help! Only thing that I would like to find are the overall rankings of their endurance test result. AFAIK it doesnt't excist, but hopefully Iäm just blind
Also sent them a letter that it would be good for something like that to excist, but haven't gotten an answer so far, doubt I'll get one.

Just get a Samsung Galaxy SIII with a ZeroLemon 7,000mAh battery for 3 days of use. They're out of stock on Amazon atm, but they should be getting some in stock soon they told me. For any phone your boss gets, go for a Gorilla gadgets extended battery.

Some years ago, phones used to have a battery life that lasted days even when under heavy text and calling activity. Nowadays, those little devices have been increasing their capabilities beyond the advances in battery technology.
I don't choose my phones thinking on battery life, I'm ready with USB cables and charges at home, my car and soon enough on my bike!

The phone with the best battery life is the Motorola RAZR MAXX (on ICS or later) by a long shot. It beats all the competitors by far.
The Motorola RAZR MAXX has old specifications, but it's not too bad. It's still better than my iPhone 4s; and you could argue the iPhone 5 too. The Motorola will still handle all your daily tasks no problem.
Here is a battery test on the RAZR MAXX: http://blog.gsmarena.com/motorola-razr-maxx-battery-life-is-complete-makes-chargers-feel-lonely/
