HD2 battery test...

I am having problems with my battery life on HD2.
Currently I use ROM Duttys Leo V2.2 with radio 2.06.51.07, but I tried atleast 10-15 different ROMs and radios (Miri/Laurentius26/Xanny/Sternas ROMs and others with all bases from 1.66 up to 2.10).
I made several tests with tbattery and logged the results, this is what i get (Current values):
- screen off -> -13
- screen on 10% -> -83
- screen on 30% -> -102
- screen on 100% -> -214
The tests were made on 2G connection with max signal, with no data connection.
My battery usually barely lasts 2 days with very light usage, with moderate usage i have to charge the phone every day. Maybe this is normal, I just hope it's not...
Can someone throw up some comparison numbers please? I already wanted to bring the phone back and demand a new one but I am not sure if something is actually wrong with it.
BTW, I use MTTY for flashing and always do a hard reset after the first full boot. Tests were done with a clean ROM install, with no aditional processes running.

verry much like this
anyway its normal im affraid of with moderate use and the end of the day i have about 40% left.

Yes, perfectly normal battery life, sorry to disappoint but that's how it goes with smartphones

It is running a computer spec, that, not even 8 years ago, had to rely on mains power. Not to mention the internet router, the screen, the GPS device, and not least the phone which are all inbuilt. I think running it for a day on a battery is pretty impressive personally.

Thanks for the info guys, I feel much better after reading that battery post from kilrah...
I was sure there is something wrong with my device, but when I look at it from rp-x1's point of view, I guess it's not that bad...

Sorry to put a downer on you, but its the way I look at it. I know it isn't the biggest capacity battery, which does have a bad effect on battery life, but unfortunately it is a computer with a phone, rather than the other way round.
My previous phones:
Nokia 3310 (basic phone) - a week
Nokia 7610 (one of the first proper mainstream "smartphones" by Nokia) - 3 days
Nokia E90 Communicator (their flagship smartphone) - 2 days - at a push
Sony Ericsson Xperia X1 - 1.5 - 2 days - at a push
Blackberry Bold 9000 - a few days, if I don't actually use it.
HTC HD2 - 1 - 2 days (dependant on usage)
It seems to be the norm for a smartphone/pocketpc to be around a day to a couple of days on a charge.
To add a bit of perspective, my colleague has an iPhone, and it lasted a whole 3 hours on a single charge when using Exchange Push-Mail. It usually only lasts a day too.

At least on the HD2 you can change battery and go on

Yes you have a point there, when I had my iPhone and used it as much as i use HD2 last few weeks the battery was about the same...

so true i bought a battery from ebay ( was only €4 and its almost as good as the original one, it only fits a bit too tight..) i always have a spare fully charged one in my wallet

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.

Why does Android on the HD2 eat up so much battery

Hi Guys,
I was wondering why Android on HD2 eat up so much battery. Earlier I was thinking, that android is running of SD card...so its the case. However this is not true as in Android HD2 NAND thread its been mentioned many times...that battery won't increase significantly even after NAND install of Android, so where lies the problem...is it because power management drivers on hd2 android not good enough...just curious?
Regards

There must be a problem with your android build or you are not properly managing your battery life. To enjoy good battery life you need to disable radios via power control, and keep screen brightness low.
Current widget tells me that in standby my hd2 uses 3-7 mA. This draw is fine when compared to similar android devices.
Please provide some details on your build and your reading from current widget.

I think he was asking about how much the HD2 life in android is shorter when compared to WM6.X
If this is the case, this has much to do IMHO about how Android works in its innards.
The Android OS has a way of controlling the apps installed in it, to know which apps do which kind of stuff. Like, when a new app is installed it has a file that tells the OS all features it does, and which of those features can be called by other programs (an example is the gallery 3d, that can be used to open pictures of certain types, every time a file that it can open is accessed android asks [if you have more than one type of gallery] which app you want to use to open the picture).
With this kind of control being done by the system in real time in a way totally different from windows (register??) the OS probably need more awake time and probably use more battery.
With the same amount of time spent using similar stuff in windows mobile and android, WM really rulez in terms of Battery Life. BUT I really prefer the new life Android is giving me in HD2. I'm really happy again, feeling like I have a brand new toy again.
P.S: I'm oversimplifying the way this works, without even mentioning the services, widget services, and several other stuff that are running in the background all the time.

i get about the same battery life in winmo n androud. make sure u have a good radio n compatible rom.

People always say those things...
Well, let me just say that I'm using one of the best combos out there, and yes I have tested almost all combos you can imagine by my self in my own phone, so I wouldn't rely on someone else's idea of a perfect combo.
Tested more than 10 roms (the list is long so, I wont bother saying all of them, but the most used ones are there, Chucky, Miri's, VBNrom, Dutty's, and several others.
About radio... 2.10, 2.11, 2.12 and now 2.14 I have used all of them too and combined them with each rom...
Right now the best combo FOR MY PHONE and in my opinion is VBN 3.14 and radio 2.14
Multi boot, autoboot android 6sec.
I really think that what is most important is the build, with the same builds, almost all WM roms made for android, and Miri, have the same effect for me, the radios I must say that 2.12 and 2.14 are the best, and 2.14 has better reception in my country, for me.
So, as I have said, FOR ME, the best combo is resumed to VBN 3.14, radio 2.14 and any android build, right now using Desire HD 3.1 from Mdeejay with several different kernells (still testing them)
The kernels and the build are the MOST important thing after you find a good combo.
With the best build/combo and a good WM rom, doing similar things (surfing the net for the same amount of time, phone in sleep mode for the same amount of time,same time talking and etc. the best battery life is surely for WM 6.X hands down.
BUT if you are really getting the same Bat life, you are a lucky guy keep the settings you have, because I must say that I have constantly near me 5 HD2 (from friends), all of them with android now, and every single guy says that the bat life is nowhere near WM 6.x
I could go a full day in WM6.5.3 and have 50-40% remaining in the end of a day with heavy usage. Android, with moderate to heavy use, I'm happy if I can reach the end of the day, and even happier with some bat left
Greetings, Santroph.

I agree battery life is not comparable to WM6.x. People who claim they get the same battery life most likely have a buggered up WM6.x setup or they don't know how to manage power/settings.

Which App are you using to monitor power consumption?
Currently I use PowerTutor.
One time I wondered how 30% of power were lost over night?!
So battery lasts maximum one day until it's empty.
On WM 6.5 it lasts for about 2 days, like santroph already said, too.
A friend of me told me, his HTC Desire has about 80% in the evening. Do they have a better battery?
In usage I have about 540-600mW
He has got 550-650mW
So seems the same power consumption.
Regards

HD2

I actually get around the same amount of battery life as well. Just running the stock Froyostone 2.1 without tweaks (don't even know how to do tweaks if my life depended on it). Current Widget shows 0mA when waken up from screen off and hovers at 3-4mA with screen on and idle. Battery drop 1-2% per hour over night.

I have TMO US HD2 and I'm using NRGZ 21916 18Sep ROM with 2.14 radio. For android I'm using pongster's HyperDroidSense V1.1. I'm using only 2 widgets HTC Analog clock and Weather channel. I have set the screen brightness on automatic and to tell u its quite dull, not at all bright. I've also disabled all Background sync's and no WiFi or bluetooth is enabled...
I do like to fiddle with my phone every now and then...but its not heavy use, I would say its moderate.
Battery life i'm getting is by the end of day, the battery is drained and have to recharge.
Before this android ROM i tried warrenb213 CM6 9/6V1.5a which is claimed by some user's to give best battery life on TMO HD2. Its stock android rom with CyanogenMod...battery life was little better, but it was slow and it didn't had instant wakeup...it took 2-3 seconds after pressing the button to wake...and personally I prefer HTC Sense UI to stock...
On WinMo my phone easily last 2 days with some battery % (about 20-30) left and can easily give me third day too with light use on 3rd day. And by no means i'm using a minimalist WinMo setup...I have CHT v1.8.5 and the same analog clock with seconds hand enabled.
So battery life on Android << that on Winmo. About the argument that Android uses more battery due to how its build. I don't think its the reason, because HTC's other phone like Desire or Desire HD have the same 1230mAh battery and have similar specs...but there battery life is similar what HD2 gives on WinMo.

Also, you must bear in mind that comparing the HD2 to the desire with battery life, the desire is obviously going to win. The desire has been made by HTC to run Android, unlike the HD2. The desire does have a slightly larger battery (i think) but the desire has been optimized by HTC so that it uses the least amount of battery possible I.e when in standby etc.
I don't know all the specifics but this is what I've found out
Hope this helps
Sent from my HTC Desire using XDA App

^^ya, i do understand...but to me its happening like battery life on hd2 w/ android is like 15 hours from 7am in morning to 10pm in night....WinMo give easily gives like 50-60hours depending on use...desire has similar as i've heard...
Agreed not optimized, but I expect it to give 40hours with full charge?

It is not optimized I guess? I get 6-7 hrs on winmo but 5-6 on android.

We can't compare with Desire, even if the hardware are really similar when looking at CPU/GPU, RAM, radio and stuff like that, we have e HUGE NORMAL LCD screen, that really takes way much more battery than Desire's Smaller Amoled screen.
Recent tests have shown that the new desire with Super LCD (thats way better than ours) do waste more energy than the AMOLED one (despite what HTC has to say about it).
I think that we should compare it with our own phones with WM, and probably with the new Desire HD or Evo 4, which have the same Case/Screen and very similar hardware too (despite Evo beeing CDMA).
IMHO...
P.S: People say that the SD card doesn't have anything to do with the battery drain, and that nand should be the same. Well I can say that this IS and IS NOT true... It all depends on which card are you using. I have 4 MicroSD cards, and they all have different behavior with the same combo/build/kernel/battery, even when in sleep mode with everything else (connections and all) disabled.
I have used WatchDog to see if any program was strangely making this happen, and I didn't find anything at all different when the Hungry SDcard was using that much battery, it was all it's fault.
2GB class 4 -> 5-7ma stable
16gb class 2 -> 3-7ma stable
8gb class 2 -> 5-9ma stable
8gb class 6 -> 5-80ma not stable (can be ina 5-7ma for hours and suddenly be in more than one hour in 40-80ma)
I prefer to use the 16gb class 2 for more battery, since the performance is not that better with the class 6 in android.
I've tested this a lot, and retested.
Greetings, Santroph.

I think that the HD2 battery is shortened by the display (Samsung Vibrant is awesomer in that respect) as well as the processor. If I throttle the processor down to 384mhz and keep the screen at 33% (automatic backlit) then I can get pretty decent battery life from 15-24 hours?

[Q] Just how reliable is WP7? How good for daily use?

I found my battery life is around 8-10 hours for minimal usage using WP7
specification using
hspl 2.08
radio newest one
sdcard 2GB sandisk
gprs always on using 2G
location turn off
using light background
sync email every hours
so I wanna compare with you guys here who using wp7, is there any one who can get battery life more than 12 hours or so?
with Android I can get more than 24 hours for minimal usage ( call, sms, browsing ).
is it better to reflash/hardreset wp7 again?

Well, I have been using it for about a week now and it is bearable, but pretty and extremely fluid
Regarding battery, I only use wifi, so I have 3g off and I surf about 30 min a day with it.
30 min phone calls
15 SMS
Update Gmail and Facebook about 4 times a day.
Play a bit with the phone and it lasts me from 8AM to about midnight that is when I need to charge it again.
So about 16h.
The worst thing about this is that the camera is not really working (all the pictures I've taken do not look as sharp as with the other OS).

I am not sure about wifi I barely using wifi, always connect with 2g connection... camera sih ok with me since I am never using camera ( only once or twice a week)
just found battery life is kinda disappointing when using WP7.
I consider if my sdcard is not compatible or what. hofully some one here can help me, if mostly can say then can get more than 15 hours so I am pretty sure I need to reflash/hardreset or even change my sdcard to get better result of battery life

From the reviews of some other devices on WP7 etc, it seems as if the battery life is an issue in general as is the case with most of the smart phones using these OS's in general -

I've been using it now for a week or so and it fit's my needs perfectly.
I've found only 2 bugs with it mentioned elsewhere by others and even they're nothing worth noting...
Camera doesnt work correctly (i hardly ever use it)...and there's issues with loudspeaker volume (workaround - set at 3) ... other than that nothing...
I'm finding after a full day of use, (wifi and gps switched on) from 8am, an hour or so of music, 15-20 minutes gaming, 4-5 calls and several texts, emails, facebook etc, i have around a quarter battery left at midnight.
Cheers
Paul

Battery life is surely not amazing, but for me it's acceptable. maybe 1-2 hrs less than WM6.5. I make it from 8 am to 7 pm with 30-40 min calls. 3G always on. 1 hr IE on 3G and some 30 min. 3D gaming.

so its 11 hours for average usage.
I just wondering if sdcard class with affect battery life? since wp7 is kinda like raid0 which cannot be separated between internal memory and sdcard.
hopefully with higher class of sdcard if will affect battery life for wp7

I have been using it since last week Thursday and its been excellent for me, I even think the battery seems better than on android. Its been my main phone since. The still camera is the only issue I have. I think iPhone has a worthy competitor in WP7.

judging by you're avatar 7pm is probably close to your bed time anyway
I'm really enjoying wp7, running for 5days now and mostly smooth.
Some apps like IE stag occasionally and some times the touch screen seems a little unreponsive mainly in settings screens.
Obviously not the easiest of OS's to switch in and out of like android due to the sd card, and not being able to charge the battery when the phone is off is an issue.
Main concerns but tolerable:
Not being able to sync directly with outlook (gmail workaround)
Battery drain is excessive (though i'm not usually far from pc->usb charge
Lack of software (obviously, but also finding the good from the bad)

Do not forget the sms receiving issue people. Been using for three days straight and all working fine but suddenly sms seems to stop coming.....and by that I mean it would take hours to recieve or send an sms and when it finaly does come...no notification and no home tile count. And trust me,,,this is not sometning to do with the settings.

battery life is really bad for me.
on a 10 hour shift on android i can finish with 40-50% battery left with full data sync on
on wp7 i had to charge my phone at work ( i wasnt sure of exact battery % because i couldnt find this function
im going to dual boot wp7 and android cause wp7 is cool for showing off haha

Works great for me, basic things work great and battery life is ok. I can do a full day with and i do play around make some calls and sms. For me it's as good as android from nand. Too bad camera doesn't work correctly and multitouch.

It works awesome, though I have the problem here, that the monthly internet package from Vodafone Romania isn't too big, and I found out that this is a 3G hungry OS. (180MB in 3 days, and that is NO downloading of apps!)
That and only because of that, I have to consider rolling back to Android.
Other than that, WP7 is one hell of a mobile OS, that runs very nice on our HD2 phones and would be good for daily use

I'm very satisfied with this first WP7 release for the Leo. Almost everything is working fine. Except for some bugs which are a little annoying (as mentioned before):
- managing the volume (it's very loud! the alarm in the morning, too...)
- green pictures with camera-flash
- slow app installation (compared to the HTC Mozart it is veeeery slow)
Unfortunately there is no possibility to set up the days and hours for syncing with my exchange (that was possible with ActiveSync in WM6.5). Actually that's not a bug from this DFT-release, but from the WP7 itself. Maybe this will be added with the announced official update.
Finally, I don't think that I'll turn over to WM6.5 or Android again. The design, useability and flawless UI of WP7 on the HD2 is really nice.

thats kinda weird some people said they have battery life some doesn't...
I thin its related with sdcard.. bad flash probably.
Look at other thread some peeps suggested change radio rom, try 2.12 and 2.14 still got huge battery drain, even with data connection turn off

I have 2.14 radio and after all day I had yesterday 30% left. Then I charged it to maximum and left it to see how battery will drain over night, and it didn't even move. So for me battery life is better than in android.

ok that kinda weird hopefully reflash WP7 with good sdcard will give better battery life.

I found my battery life is around 8-10 hours for minimal usage using WP7
specification using
hspl 2.08
radio newest one
sdcard 2GB sandisk
gprs always on using 2G
location turn off
using light background
sync email every hours
so I wanna compare with you guys here who using wp7, is there any one who can get battery life more than 12 hours or so?
with Android I can get more than 24 hours for minimal usage ( call, sms, browsing ).
is it better to reflash/hardreset wp7 again?

I've had it running, without a reboot for the last four days. I haven't really noticed horrible battery life but then again i am not of it half as much as the Android OS...mostly b/c the apps are GARBAGE and the games are SAD.
I have wifi active at all times, 3g data is really slow for some reason.
It is usable but i would not say fully functional even with reg hack and Microsoft activation hack.
Volume sucks! Way too loud even with min volume and gps sync is all out of whack...map application looks awesome with the real street view but good luck getting to a destination!
Camera is also GARBAGE but other than the sound the 720p video looks great
I really like the simplicity of the OS layout and the fluidity of everything but there needs to be more usability and functionality before i fully adopt although this have been a good learning experience and test for whether or not i want to get the HD7 or just another HD2 for my next phone
Going back to android for now...perhaps there will be a NAND ROM soon that has at least 95% functionality without having to call and lie to MS to get codes.

I love WP7!!!
Had some battery issues to begin with, but changed radio to 2.14 and then hard reset. For the last 3 days I've had nearly 30 hours on battery. On par with Android. Android is superb as a customizeable OS. So many things you can change.
WP7 is a phone OS, pure and simple. I love the simple interface. Not much you can customize, but the speed more than makes up for it. Messaging is particularly fantastic.
Don't use a light background!!! Use a dark one (black basically). As the screen has to fully light the pixels for a white background (value of 255), using black (dark, value of 0) it doesn't have to light them as much, so the screen uses less power.
Still a few bugs in WP7, also some missing features, but nothing that is a 'show stopper'.
I'm sticking with WP7 and looking forward to the 'official' update....

Battery life WP7 vs. WM 6.5?

Hey guys,
I am considering switching to WP 7.5 from WM (default ROM) and was wondering, will I see any battery improvements or it will actually drain it faster?
Also, anyone tried Android 4.0? All I care at this moment is battery life and don't mind whether it's WM, Android or WP.

Hi!
Best batterylife you will get on this device is with WM. Find the right release (some of them have improved power management) and stick to it! You will NOT be able to find better battery-life with Android or WP...
/Anders

That's right. As far as I know, best battery life is with WM6.5. However, I'm really happy about battery life in WP7 (DFT Ultrafruit changing radios and other things). I make more than a day, maybe 2, but being careful about what I do, of course.

Maybe wm6.5 is better.
But I feel wp7 takes better pics.....weird...after taking 240 pictures of a book..the battery from 100 to 13...is this normal or power consuming?BtW,it's standby life can be as long as two days with some general use

Battery life w.r.t various ROMs are as follow
WM 6.5 (Best battery life) >> Android >> WP7 (Worst battery life)
WP7 runs constantly at 998 Mhz (One of the reason for high battery consumption) where as 6.5 and Android can dynamically vary from low CPU consumption to High as required.
Also in WP7 battery life depends on soft radio + hard radio combination.. For good performance with good battery life use 2.15.50.14 Hard radio + 5.50 soft radio.. For best battery life use 2.12 hard radio + 5.50 soft radio..
Trust this clarifies..

Very Low Battery Life...Please help...
Hello friends...
Recently I have installed WM7 to my htc HD2. I found that the battery life is very less.
I have read here that if we use the combination of 2.12 hard radio + 5.50 soft radio.
Please someone tell how to do so....?

Search the forum my friend, hardware radio is updated via the custom RUU, it does not delete anything.
Software radio needs to be built in to the WP7 ROM before you install it, changing this will mean a loss of everything
Now, whilst battery life is deffinitely less than WM, one thing i can confirm is that its not worse than android, the problem is that it doesnt always charge completely, so for example, it may say its 100% full, but its only half full, so it appears to drain twice as quick, or it might say its empty and its still half full.
It could say anything, for best battery life use an external charger. reboots during the day will help keep it reporting correctly. Tho even then ive noticed that it doesnt always work, some times you need to plug a USB cable in for a moment for it to refresh it.
In short, battery charging and reporting is all over the place, but once you get a full charge it actually lasts quite a long time with very heavy usage.

Personally, now that I've found a WP7 ROM that doesn't drain my battery in 5 hours, I don't notice a difference. (I'm now using pdaimatejam, BT on with -3 to -7ma drain in standby, Yay!).
Sure, WM will last longer. Sure Android will last SLIGHTLY longer b/c it doesn't run the CPU full speed when the display is on. And that is a clarifying statement to the above. WP7 does NOT run the CPU full speed all the time, only when not in standby.
Having said that, I get a full, usable day in WP7 with moderate use. I got just over a full, usable day in WM6.5, but I had to charge every night regardless.

Testing 2.12 now, thanks,
Now sure if estimated battery life is correct, before installing it said 5h, now 2h

also dont forget to try camera trick with combination 2.15/5.51

Does it work with 2.12?
Is 2.15 better than 2.12 in battery life?

10h standby (mail sync on) with all the tricks on HD2 2.12, bad
Hopefully, Tango will increase battery life.

you can dream.... but none updates for WP7 cant be increase battery life... only can be worse
seems your battery in bad shape or something do wrong... also if you play music few hours, play games, nothing strange if battery not least long...
with radio combination 2.15/5.51 + camera trick, with WiFi on 24 hours at day, my battery working around 30 hours with normal use

Hm, well, it said 2h remaining but still holds, another 6 and has battery left... No idea.
I will play with soft/hard roms after Tango is released, as now floashing and losing data for a month or two is pointless
Thanks!

I have actually had better battery life using Pdaimatejam ROM with radio 5.51T/2.15 combo than I had with Android or WM 6.5. Not exactly sure how but it is definitely the case if any of you want to try that

on my hd2 it feels longer with wp7 u can try it on your own

yeah

2.worse battery life,excellent speed=windows phone
3.good battery life and reasonable speed with freedom to do things that you cant in wp and wm=android
i prefer wp7 and sd android and i have to charge 2 times a day (ok i have 2 batteries and external charger so i change the old one and i am ready to gο) but i have a phone that i enjoy to use
