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..

Battery Life Problem with HD2 - Help Reqd

So I finally got rid of my iPhone 3G (jailbroken on T-Mobile), and got an HD2 instead. I've always liked Windows Mobile phones (and had most iterations), and since now there is finally some capacitative goodness on WM, I jumped on the opportunity.
And I'm regretting it already.
I'm hoping that somebody here has some suggestion that my two days of thread searching, and experimenting didn't cover.
The problem is, yay, .... the damn battery.
I left it on the charger from totally empty to completely full at 2AM. At 8AM, it was down to 85%. Ten minutes of reading e-mails, 74%. The thing is really not usable in this state.
Here are all the things I checked already:
It runs the latest T-Mobile ROM and radio (the one that just came out a few days ago).
Latest version of .NET (3.5.9).
No push e-mail, e-mail checking once per hour, weather checking once per hour.
Strong 3G coverage area, still tried out WMLongLife anyway (with no difference).
Did several cycles of full discharge, recharge.
Always check task manager, not leaving programs running.
Nothing else is set to go online - Live is disabled.
Screen brightness is set at 30%.
All charges done via wall charger.
I read every post I could find, especially fun the ones where people get 4 days of standby, and 6+ hours of heavy use. Short of loading the ARTEMIS ROM, I exhausted all options I could find. And really, it seems like people get decent performance from the stock ROM, so I'd like to stick with that for the moment.
What am I missing?
So frustrating. I can see how this sort of thing would make the average "just user" go run for the Android or Apple hills. No wonder we get stuck with restrictive babysitting technology, when others can't get their **** together. Spend $450 on a phone that can't make it through a half day of reasonable use? Argh!!
Any suggestions would be greatly appreciated.

same here
i have all the same problems my batt just sucks i figure i have to just by a new one

hey man, i was like you at first too. all my mates had iphones (i dislike apple in general) i didnt want one. At the time o2 (uk) didnt stock android phones and i had a sony x1 previously. So, i got the hd2 and...like you said was disapointed.
Changed the rom to a custom one here at xda (hdowners btw) which lasts 1.5 days (heavy usage)...never seems to get 2 full days when i use it alot.
installed a few different browsers (opera 9.7 and 10)
installed morphgear (with some amazing landscape skins)
fpsece (i found time crisis to be the only actual playable game)
coreplayer
and found it a awesome phone...changed my views on it. Try some custom roms and see what you think...usually you will go mad installing themes, skins, apps...just go wild and keep the ones you really like/work in a seperate folder. Then reflash and install the best only...thats how i done it and i now love this phone
good luck, im sure the rest of the forum will give you some advice.

wayandrs: The main thing that will help is by upgrading the ROM even if it is to stock 1.66 (the latest UK one available) then you notice a large difference and even more so with some of the cooked ones. Other things to note are the WiFi, make sure it doesn't be left on (and only turn it on if you need it) it proper drains the battery. Without knowing your habbits with your phone it is very hard to come up with decent suggestions that hasn't already been posted elsewhere.
I can safely say I get 2-3 days use out of my device but then I don't use it all that much (anymore), don't forget as it is a new toy for you, you will keep playing with it seeing what it can do, this will soon die down (as it always does) then it will be better.

there must be something wrong with your device or battery.
mine lasts for about 3-4 days while middle use. i think for such a powerful and huge device, this is more than respectable.
heavy use...mh...i would say it lasts minimal 2 days, sometimes more.
did you write a complain to t-mobile?
DN41

The battery will improve after a week or so .
Note : charging your battery the first time for only 6hours isn't much , the first time that i charged my battery i left it charging for 24 hours.
Updating to the latest ROM and Radio helps .

I have two suggestions:
1) Take your phone back to where you bought it and let them deal with it. I get at least a full day with heavy use which is to be expected from a high end device with a 4.3 inch screen. I spent a few dollars on a car charger and an extra wall charger for work, sorted.
2) If you want help on these forums leave out the useless complaining about what a rotten device you have. I think I speak for many contributors of this forum when I say that these kind of posts are getting old and wearisome. You will be more likely to get polite replies with inteligent suggestions if you simply state the problem without moaning about the horrible mistake you made in being seduced into buying an HD2. I have purchased phones that I simply did not care for. I returned them.

First step: Flash a decent ROM with most of the performance/battery tricks in there already. Many of these ROMs are constructed from the best (often most battery efficient) parts of multiple ROMS.
Touch-X, Energy, Artemis, CleanEx, etc. All are excellent (though I favour Touch-X myself for a great utility/preformance/battery balance).
Second step: Flash a good Radio that works well in your area but also works well with the ROM/has decent battery life. You'll need to research this for your chosen ROM.
I use the Korean radio in UK. Good quality/signal/battery life.
Run it for a few days, charging to full and emptying the battery before recharging to full again. Do this for 3/4 days at least.
Those changes alone got me upto 2.5 days standby and 4 hours usage (thats movie playing for 4 hours with 100% backlight in a hotel room). Good for a smartphone and longer than my friends IPhones.
Other small programs like WMLongLife, adjusting down the backlight automatically, added another .5 days to standby (though not much to active use life).

Yes, sorry I fell back on the usual retoric.
I do wonder though if when someone buys a new 'Toy' that they dont hammer it to start with for the 'joy' and never think of the consequences.
I like you, no matter which phone I own, being a businessman and needing maximum performance have a charger at my bedside (the phone is my alarm) and also connect it to the car charger when driving.
I wonder if many of the people that move up from a basic Nokia phone (or similar that can last a week) realise what is involved in powering all the functions they require?
Please don't quote iPhone as it dunt do half!

try elegencia rom v 8.5 and reply back

I use the stock rom 1.66 from the beginning and check my mail automatically every 30 minutes. Now and then I check some websites and download cabs and use HSDPA/3G and WIFI if available. My battery is 100% in the morning and 70 percent in the evening. Not bad at all. The first 12 times I fully charched the battery during the night.
I use Bandswitch, which automatically disables my connection within 30 seconds. This is the most important and useful tip! You don't need a custom ROM to solve the battery drain issue.

+1 - Lovely ROM

it looks like you have not a windows phone before

Thanks.
Thanks for the ROM suggestions. I'll try a few more days of deep cycling the battery to see if that helps - if not, I guess I'll try a custom ROM.
And yea, to those 'get a life' and 'don't complain about Windows phones' posts, whatever. I've owned Windows Mobile phones since they first came out, and it's just frustrating that the out-of-the box usability hasn't gotten any better to this day. Looks at the cool people that actually manage some constructive feedback - they are who make XDA forums great. Thanks guys!

A new 1200 battery is 15 pounds (the official from HTC) as a backup. I personaly have bought the extended battery 2400 and it is great. The default battery doesn't last the full day for me because I use it constinuosly as mp3 player , brownsing and video player. I mean, you have options.

ROM
I'll be trying the Elegancia ROM.
That is, once I find a ROM with 2.8 SPL that works on my 1024 version of the H2, to reflash mine so I can get HSPL to work to flash.
I've always really liked Windows Mobile for its flexibility and massive base of developers ... on the flip side, I've been screwing around with this thing for several days now, trying to get a phone that can last through a day. Ahhh, the bittersweet experience that is WM.

I get at most 2 days combined cycle out of my stanard battery and i've had my phone for about 10 days. It came with the stock 1.66 rom but i've run through the tips and tweaks threads so the phone ui is faster and a bit more usable. One of those is a replacement task manager that disables smart minimize in favour of actually closing programs. I've also set the weather software to update every 3 hours because tbh you don't need it to be any more often than that. I do use the wifi alot but i do turn it off when i'm not using the phone. i have also noticed with my phone is if the wifi is connected to an access point for more than 5 minutes it will automatically disable the 3G connection and turn it back on when the wifi is disabled.
for the first couple of days i was completely discharging the battery and then charging it for about 12 hours. this seems to have been the most beneficial. i also will not put it on charge unless it really needs it.

hi, from experience, 3G medium usuage.. 4/5 a day.
If you disconect the 3G connection when not using, it will help.
And of course if you go on GSM instead, one day is not difficult..
battery killer :
1) constant 3G activity
2) Watching video. Worst, video on 3G !
3) games, especially the 3Ds ones or high on processing like the Tower simulation game.
4) bright screen
5) bluetooth

From my experience, from a fresh flash, my battery improves as I get to use it longer and longer.

take a look at your data sync like weather and stock and also check the social networking sync.

Nexus One Battery Life vs iPhone 3gS/4G

Earlier this year, I was a huge Android fan. I had a rooted G1 with a different firmware every week. My Dream ended when I realized that the battery was lasting me not more than 5-6 hours, even with very light use. This was after swapping out batteries/phones. Also, for working out, I needed a good music player. Android's default one needed a LOT of improvements.
So, when my friend brought over his iPhone, I decided to give it a try. I bought an iPhone 3GS from craigslist. Jailbroke and Unlocked it. The battery was lasting me more than a day, even after watching more than an hour of TED.com talks, and listening to an hour of music. The ipod functionality was amazing with the volume/music controls in the earphones.
Then, I accidentally updated my phone to the latest firmware... which cannot be unlocked. So I'm back to using my G1.
So, the question still stands.. Is Froyo on Nexus One better in battery performance and iPod functionality of iPhone 3GS. Especially with the upcoming iPhone 4G, we can be sure that Apple will increase the battery life of iPhone (as they've done with all previous updates)?

I get a lot better battery life with Froyo then on my 3GS to be honest. Also, as far as the music functionality goes, why do you think its so bad? If you dislike the interface, then you can download a alternate option from the Market. But for me, as long as it plays the songs, view/edit playlists and browse the music I am good to go.

i got slightly less battery life from my Nexus with 3G turned off compared to my jailbroken 3GS.
normally ended up with about 10% less battery at the end of the day compared to my IPhone and similar usage.
the Nexus was stone stock.

Thanks for the replies...
To answer the question about music interface... I think the ipod interface is much smoother than anything i've seen in Android (please suggest something in case I might've missed it). As I mentioned before, I use the earphone controls A LOT.. and am not sure if Nexus One will offer the same functionality.
Battery life is a huge issue for me. As I said, my usage on iPhone was pretty heavy. Let me lay it out here -- this is with Edge.. Push On.. and Location On.
- 1.5 hrs music
- 1 hr video (Ted talks podcast)
- 1.5 hr phone calls
- 2 hr games
- 3 hr Wifi on
With this kinda usage, my iPhone would have 15-20% battery left by end of the day (midnight usually)...
Does your Nexus One match that or is better?
( I'd love to switch to Nexus, if battery is a non-issue... love the Google integration!)

Battery life is across the board on the N1 for some reason. People will have the same set up and get very different kinds of battery life. I know I've never been happy with the battery life of the phone.
A good music player is ³. Cubed. I like it. I recommend the Nexus One if you get the 2 batteries and external battery charger for 20 bucks deal off of eBay. Maybe life will increase but until then having an arsenal of batteries solves my problem.

Ok, I guess I'm back to 8th grade, basic math. Let's calculate. And because you could have just looked in the specs and done the math yourself, I'm not going to look there, and if I bring the wrong numbers - so be it.
1.5 hr of music is almost nothing. Music is optimized for very low battery usage - 20 hr of listening or so. Let's say, 5% off battery.
Wifi on is nothing. You can keep it on for as long as you like, you actually save battery - it turns off 3G/HSDPA and uses WiFi data.
1.5 hr phone calls out of ~6 hours spec ~= 25% battery off.
1 hr video out of 5 hr spec ~= 20% off.
2 hr games are quite destructive. Both CPU activity and display. Let's say, another 25-30% off.
You're left with approx. 15-20%. Surprised?
Oh wait... It figures, no? Do you think one of those systems is going to be significantly inferior in terms of battery life? You don't think Samsung and Qualcomm know their stuff well enough?
Ah, and the difference is going to show if you use Android power and load it with zillion auto-updating and auto-syncing widgets, that'll chew on your CPU idle time and use up your network power.
[edit] That's exactly the reason for varying battery life between users, as the poster above noted. People use their phone differently, and unlike iPhone, it can perform a lot of things simultaneously, without you even noticing (it's enough that you installed auto-syncing widget and made it sync once in 5 min with a good amount of data, for example) - and it'll cost you battery life. Control what you're running, and you'll get more out of the battery.

I came from an iPhone 3G to the Nexus One and the battery life does seem worse. it's always hard to compare because I do more with my Nexus One. My gut feeling though is even if my usage is similar to what I would have done with my iPhone, the Nexus One just uses more power. Part of that may be the higher res screen. Battery usage almost always shows the display as the biggest user of my battery.
I recently have been having worse than normal battery life. I'm not sure if it's due to upgrading to Froyo or if it is because I turned Latitude on. If it's Latitude, then it's really frustrating that the Battery Usage area doesn't list Latitude as using my battery. Kind of makes that a pointless feature if things just get hidden under names like "Android System".
I also agree with you on the Android music player. I use it, and it's not terrible, but the iPod app on the iPhone is just much easier to quickly get to the music you want to play. Also the Genius features are really well done. Someone suggested Cubed. I found it gives a really good first impression but once you use it you realize it's actually just flashy and it functions awful. As far as I can tell there's no way to quickly find and play a single song with it.

Battery life for 3gs is better than nexus..

For my usage the battery life on Froyo is about twice as good as the battery on 3GS. Granted, I listen to slacker radio while browse websites for about 2 hours a day and the multitasking on android is much more natural than the jailbreak alternative.

I am not altogether sure you aren't just trolling. There isn't any way to give a definitive answer to this question, but I'll give you my experience.
No new N1 user is going to say he gets good battery life. You won't want to shut the screen off for the first week.
Now, I can get a day and a half out of my battery on a stock rom if I don't sync absolutely everything frequently, I use wifi when it's available, keeping radios I am not using off and basically, being mindful of power use. I use it frequently, but not constantly. And if I am away from a charger, I have an inexpensive spare battery that I can change all by myself without any special tools all the while sending SJ a FU via ESP.

Thanks for all the inputs...
Lemme get first thing straight.. I have NO intentions of trolling No harm intended. When I bought the iPhone, EVERYONE I know was immensely surprised. I was (and still am) a spokesperson for Android. I love the apps. Maybe thats a reason that we all install so many widgets/apps which use data.... So many are available for free!! and awesome ones too.. for example.. I'd kill for the News and Weather app to be in iPhone.. but its not...
As I said in the original post.. a big chunk of my criteria is battery life.. second big chunk is music... I guess I'm sad that no Android phone yet can beat the battery life that an average iPhone user gets... I was hoping by releasing Froyo, google would change that (hence this thread)...
Trust me guys.. I live by my gmail.. would rather have everything centered around it... than having apple control my life... just dont wanna carry around extra batteries.. like i had to for my g1...

Intersectraven kernels with any nexus one Rom gives me the best battery. Rite now I'm on froyo and have lasted more than 20 hours with the kernel.

Now that I'm using my nexus normally, I'm getting good battery life. 12 hours of solid usage.

Which of Raven's kernel are you using?
I have a iPhone 2G and it beats my N1 on battery but not considerably.. I read that the 2G is teh king while 3G is the worse of the three iPhones. 3GS is slight better than 3G.

Something that people keep mentioning but seems to keep getting overlooked when people compare any device running Android to the Almighty iPhone...
Multitasking. Takes. More. Power.
Being able to run 5 or so apps in the background (along with all the automated syncing that's happening on the network-data side of things) is going to drain the battery more than doing one thing at a time on Apple's product.
When your iPhone is able to effectively multitask, come back and then you can compare the battery life.
Quite simply, Android lets you do more than you could ever possibly do on the iPhone platform. It gives you the option (free will - unheard of on the Apple side of things!) to run a handful of apps simultaneously. This, naturally, uses more power as the processor is doing more. This is not rocket science, people. You choose to do more, so accept the power penalty. Or, you can be mindful of your battery usage and manage things appropriately to get a significant battery life improvement. It's your choice!
And if you still don't get enough battery life out of this more powerful, more capable device, as attn1 pointed out, there is absolutely nothing to stop you from getting an inexpensive spare battery that can be swapped into the phone in under a minute (INCLUDING the time it takes to shut down and power back up).
Trying to compare any recent Android device to Apple's iPhone is like comparing my gaming notebook to my old TI-84 graphing calculator - which did get much better battery life than my current Asus G72 notebook.

By 7:14 I'm at 64% charge.
In 2 hours doing what I noted here I lose close to half my battery?! That's laughabad.

It's amazing how all over the place the returns are.
I have owned the following phones in the last three years :
iPhone 2G
iPhone 3G
BlackBerry Bold
iPhone 3GS* (borrowed for 2 weeks to see if I wanted to go back...)
Milestone
Nexus One
I, personally, got the best battery life out of the iPhone 2G - I got three days out of it, consistently. BUT, I did not have an unlimited data plan, I did not use it for mail, I always got apps from the store over WiFi, I never streamed music, video or anything else. I had no RSS reader. I listened to some music, played the OCCASIONAL game, sent some texts and made a few calls.
Next would be the Bold. I POUNDED that thing and ALWAYS got at least 2 days out of it. I would send dozens of SMS, read and reply to at least 40 emails/day, use GTalk with my wife for at least 50 messages a day. I'd read RSS feeds with Viigo.
After that, every single phone on the list requires charging every single day.
On the iPhone 3G, I would do a little surfing, maybe a little video, some emails and some text. Music on the metro coming and going to/from work. Charging every day was mandatory.
On the 3GS, with how App Store had better and better stuff, I killed it (as in forced shut down) 5 out of 15 days - all that with no widgets and no multitasking. I would read Le Monde, do some browsing, read tweets, read emails, make a couple of calls and texts. I started stocking the charge cable at work and in my backpack during my weeks with a 3GS, because it wouldn't make it through a day. Most friends and colleagues who have them do the same.
I received the Milestone in December. I loved it, and really started pounding a phone - 100 GTalks a day, some SMS, all email, NewsRob for RSS, Le Monde, News & Weather widget one we hacked that on there (following the Jan 5 release of the N1), twitter and facebook, browsing. App downloads, widgets left and right, plus CONSTANT dev work, image building, flashing, testing, etc. I would get a day if I took my foot off the gas, but if I pushed it too hard, I would kill it. There were a couple of battery killers that were avoidable but which I didn't avoid from time to time - leaving Qik, the browser on the google homepage (with autolocation on) the Camera or Maps open, then letting the phone go "idle" with the screen asleep keeps the GPS on and would eat the battery in an hour or two. This left me high and dry a couple of times, until I paid a bit more attention. The Milestone got better 3G than any iPhone and worse / less-consistent WiFi.
I picked up a Nexus at the beginning of March. It gets somewhat-to-significantly better battery life than the Milestone. I still have to charge it daily, but there seem to be fewer battery-death bonehead choices that drink the go-go juice and leave you without your electronic BFF. Most of that is probably Android 2.1 and the UV kernels - I noticed that the Milestone was better with 2.1 as well. It also gets 10dbm worse radio reception with the same SIM on the same desk on the same network in the same office. But it gets MUCH better and more reliable WiFi, and that is better still since FroYo. I use it a ton - RSS, chat, SMS, calls, LOTS of browsing, Le Monde, NYTimes in Newspapers Full, lots of games in spare time, Google Listen for Podcasts, Music, Movies, taking pictures and videos and posting them online with Twitter, Facebook, YouTube or Buzz, etc.
The Nexus has one MASSIVE problem, as far as bettery goes - charging it on any computer USB port, and many thrid-party USB charge plugs (AC or DC) is atrocious - hours and hours to get just a few percent. I don't know why - Apple can use 1A from anything, RIM / BlackBerry can come close to 2A. My Milestone would take at least 1A from anything. But the stupid HTC kit won't take more than about 400mA from a computer or a non-shorted USB charger. SOME 3rd party stuff will be exploited up until 1A, as will the charger that the N1 comes with, but if not, you're going to see slooooooow charging.
As far as the music player: I want 2 things - good sound and the ability to pause and skip with the mic button. Every iPhone does this, and so does the N1. The N1 DOES support headset buttons (it's own set comes with them), but I use my Shures with a simple mic adaptor. I almost never see the interface - I put on a playlist and shuffle it. DoubleTwist makes sure that I have the same lists on my iPod touch and my Nexus, so I really don't notice the difference.
If you use the interface a lot, well, then the player on an iPhone is the best there is. I just don't use the interface often enough to make that a selling point.
As far as sound - the Milestone got SIGNIFICANTLY more volume and better sound then any iPhone and a ridiculous amount more than an N1.
Froyo just rocks. I miss a couple of CM features, but there are sooooo many good things baked into Froyo - tethering, copy/paste in received GMail messages, SD card app storage, cloud-stored settings, Flash, incredible performance.
Your Mileage May Vary.

Thanks for the VERY detailed post... And also for clarifying the controls thing... thats awesome that N1 uses the mic button for controls... I use it a lot while running to skip songs...
I'm on the brink with my G1 though... Flashed the latest 2.1 ROM from Cygo.. at first I thought it was fast.. but now its driving me crazy.. its not really the ROM but the phone itself.. will post a video of the experience soon..
So to summarize above posts...
- N1 can give same or better battery life than iPhone... provided.. that we use it well... no crazy widgets/apps which keep using data...
- The earphones button CAN be used in N1 to skip songs.. which is awesome for me...
I think I might order my N1 today itself.. as it's still being sold on google (surprisingly enough).. Who knows once only T-Mobile sells it, if they'll stop offering the unlocked option....
Thanks for all the input guys

Am i Just Lucky ???

Been reading on here about people moaning about there HD2's and i got to say when i first had it i had the 1.48 rom and had issue's...
But a bit of reading mostly on this forum and a custom rom later and my HD2 has been perfect...
I've had no issue's really, occasional glitches but nothing other than that..
Well happy and for what i do its perfect there really is nothing else i would rather have...
So my point is have i just been really lucky and had a good HD2 are there bad ones out there ?
Or are people creating there own issue's by tinkering too much or in some cases too little, pretty much i've just put a rom on and apps that i like i use my HD2 a lot obviously for talking, texting and web browsing and i can't remember the last time i had to reset the device, last night i checked the battery after a full day use 60%, seems pretty good to me...
So am i just lucky ?

yes yes and yes.

i have been really happy with my HD2 as well. did the official vodaphone rom upgrade which was really easy. have a few apps on it. mainly use if for co-pilot, memory map, e books, music and movies. oh and as a phone as well lol.
cant recall any major probs at all. occasionally have a situation where the battery drains quite quickly, but i think that is when the phone has to range for a signal when reception is bad. its not a regular thing though and generally get a couple of days before a charge is needed. i was lucky to get a days use out of my i900.
i agree that too much playing with the system may result in poor performance in some areas. its a bit like playing with the chip in ya car, go for better performance and watch the gas milage go down.
my only gripe is the lack of flash in opera which is not to do with the phone really but to do with the browser itself.
Mike

It seems to me that you got the best Radioversion for your phone.
Everybody that owns a HD2 are lucky
You say that your battery stays at 60% after a whole day of usage, is that with heavy usage?

Somketimes I'm lucky, and yet sometimes phantom issues just turn up...
I have been a happy flasher on different phones for two/three years, so I know what I'm doing. With the HD2, I purposely stuck on Stock for as long as possible (three months), more of an experiment than anything, and Stock wasn't bad, but the Texting issues were too much in the end.
My first two ROMs were not 'big name' ROMs, and tbh they were flawed - odd graphics missing in manilla, very slow at times, loads of quirks and irritations. But i chose to try them as i knew I'd end up on a well-developed ROM and be unwilling to flash again for a few months.
I just tried MaxSense but it's too buggy for now, although I expected that.
I'm reasonably happy with Energy's CHT ROM this past week, but even now I've had the occasional phone turning off, the alarm doesn't sound if my phone's on mute, but if I want it on loud I have to turn off my email alerts during the night, texting is still a b*tch (I'm tempted to get a dump-phone just for a T9 keyboard), and as ever I still feel like my phone is work in progress.
*All those flaws I've pointed above I'm sure I can fix by going through some threads, but the point remains I just want a decent experience and enjoy using my phone, not spend my life looking for solutions. I love my HD2 but at the end of the day it's a phone ffs!
Anyway, there's my over-long take on it!

I would say average usage, quite a few calls and texts i organise stuff so send group texts 25 at a time, and about 3 hours browsing on the net via wifi in the evening...
If i've hardly used the phone its closer to 75% at the end of the day although when i'm playing with it as in putting apps etc on that might require a restart the battery life drops a lot...
I always have the wifi off and bluetooth and 3g...

Ok. Well I got wifi on all day, same with bluetooth, 3g and Data conection. And Im quite a heavy user.I use the browser a few times a day I send at least 100 text-messages a day and Im always logged in to Facebook and Twitter to stay up to date. Although my battery is between 20-10% when i go to bed, and Im more than happy with that

Battery again...

I'm on Twilight DFC ( last version with htc hub )
Rom use : 2.14.50
HSPL : 2.08
card SD : micro SD sandisk 4Go class 4
Magldr : 1.3
Use : no really ( check my mails every 3 hours , 20 sms per day , little internet with 3g.
Désactivated : my 3g, wifi, localisation for a better battery level. My emails are checking just every hour by option.
Results : 100% at 8 A.m , 20% at 7 P.m ...
The battery are very drain...
with rom 2.15.50 it is the same
rom i have use : xmob 1.3 / 1.4 , moonlight ... and.. it is the same problem.
Please help me .

Same issue here. It's about 60mA battery drain, guess something wrong in power management.

You've most likely forgot to disable bluetooth completley. There is a 60mA BT bug in some roms.

bluetooth is off, but the battery running time is still bad. What Radio Rom is definitely the best ?

How to completely turn off bluetooth? It was turned off in settings

Yes, Settings/Bluetooth disable

2.12.50 with the battery tweak found in the development subforum gives me over a day with moderate to heavy usage (games, 3G internet, 3 e-mail [email protected] min, 30 min. voice calls). In standby (only mail sync on) I get 10-12% battery drop over the night.
Wait for a few recharge cycles and it will settle. At first I got 12-15 hrs. After 2 weeks it got MUCH better.

is your batter being charged propperly?
The battery tweak sets the full level for the battery.
you must first charge the battery to its maximum level then run the reg tweak
Now here is the problem, WP7 on our HD2 will not charge the full batter all of the time. Quite often you must charge until it goes green, then reboot and charge so more, keep repeating until the HTC battery tool reports the ACR level roughly the same as the FULL level.
to give you an idea
Ive just charged my phone over night, it says its full, it wont charge any more but the tool reports it only half full, even though the indicator shows full. But my battery life will drop like a rock and may report being empty when its not.
If i restart my phone just now the tool shows a jump in ACR value to about 800mAh it then allows me to charge the remaining 400mAh.
or you might find that restarting it shows the battery is full in both indicator and ACR value
The point is, after a full charge, restart the phone because until you do the phone doesnt appear to know whats goig on wth the battery, im guessing this is something to do with the fact that the HD7 and HD2 DO have some small differences inside.

I think what frustrates me more than anything else is the sheer unpredictability of my battery performance. I have done all the tweaks and installed the battery tool but overnight in the past week I have seen the battery go down as low as about 15-20% and remain as high as 80% with a range in between (estimated values, of course).
I'm now going to try to look at my data usage to see if anything is causing the radio to work extra hard some nights and not on others.
If it was at least consistent I could then start thinking about Radio versions, management strategies and the like but while it's so variable it a bit hard to get scientific with it...!

indeed it is a bit of a pain but remember we were never ment to have this ROM.
remember though it might be unpredictable because its not full, its not as easy as it sems to get a full charge, even when htc battery tool and MS tells us its full it might not be, persistant restart and charge usually gets it done

It is definitely battery problem exists! Don't try to hide it because all that stuff you are talking here to solve that is not working! Test in 2G network without any BT and WiFi during 24h failed, battery completely drained without reason.

no one is saying there isnt a problem, there are seveal problems
The big one is you shouldnt have WP7 on your HD2, our device was not supported, you cant say the HTC HD7 is the same because it is not, largely it is yes, but internally it has differences, one of these differences seem to be the controler for the battery
To be clear, WP7 cant report the correct battery level without tweaking it, and in some instances WP7 will not completely charge your phone but it may appear full there by leading to quick battery drainage

I second that. I think it's the matter of hit and miss. I have two hd2s, and one of them has ****e battery life. Both are using the same rom, same radio, same battery optimisation technique btw.

I bought an HD7 cause of the battery drainage of WP7 HD2, multi touching, downloading from market e.t.c!
I know HD2 is better than HD7 because you can have everything but... WP7 is my thing ya know??? So if you guys liked WP7 just go out there and buy your selves an official WP7 device! Believe me i l.o.v.e it and i will stick with it!
Battery life on HD7 is stunning! I have it running 3 days now and now i have 20% with moderate use..

Worse recommendation I ever saw. When first android port was released, there was huge battery drainage too but now I'm using android on my HD2 with 3 days batt life and I didn't buy new android device. So it can be fixed without wasting money.

In my opinion..Android is boring.. I know that battery life on Android HD2 is awesome but the OS is very Boring... When i flashed WP7 i said "this will be my daily OS" (i love simplicity..)... At that time i needed to charge my battery daily and i was a little bored of the hard keys and battery and stuff like that! (also i had some lost pixels on the screen) Didn't wanted to go back to Android though! So why do i have to keep my boring HD2??? Since i wanted to run WP7 as a daily OS i got my new HD7 (for 150Euro)
I am Just telling my opinion and i hope you agree with me...
I am a tech lover guy...Yesterday was iPhone, after that HD2,today HD7 and God knows what else for tomorrow!

where to get an hd7 for 150,- euro????? i'll going out and get two of them, too

for me wp7 is boring until now. almost no customization.. when you want to turn off data or wifi or bt you have to navigate through 2 or 3 menus.
and it is slow even though there are beautiful animations. (contacts open in about 2 seconds and in android it is about 0,5 seconds)
i am all for simplicity as long as you have all functions and speed.
btw battery is enough for 1 day with moderate use but forget using it from early morning and a long partynight
(camera issue still a bummer)

im all up for opinions on here....so ill give me own
Im sorry but i have not seen a more fluid and resposive device then the HD2 with WP7, iphone, android on various models even WP7 on other devices dont appear as quick as mine but thats the luck of the draw with using our HD2 some folk have had issues others think its amazing. contacts for me, around 200ish load instantly
luck of the draw
battery life is a concern still as is the camera other than that all is good

I'm not agree. You didn't notice that "super simple" WM7 consuming more energy than "boring" android? And what a point of this?
You know what, rich people always bored. I got my first iphone (3gs) just 3 month ago, and HD2 was like a gift from my friends in America.
