I-mate PDA2 Short battery life issue.

i have just purchased imate pda2(equivilent to O2 xdaIIi) and with a very minmum use after the full charge all the battery drains in just 8 hours ..Is this the normal battery life or its the fault of battery?
ROM version=1.11.00 WWE
ROM date 01/27/05
Radio Version=1.02.00
Protocol Version=1337.42
ExtROM version =1.11.144 WWE
Battery is PH17C 3.7VDC 1300mAH
I am confused about ROM size my hadware info shows..RAM 128mb Flash size 64mb....
does flash size means ROM?
but there is written 128mb ROM on booklets but it shows 64mb why>?
kindly help :shock:

I just recently bought a PDA2 as well, and experienced the same battery life problem. after running it down to less than 10% battery, then charging it back up to 100% a few times tho, the battery life appears to have strengthened a bit.
although i had a relapse last night, it was on 34% battery, i turned on flight mode, and then put it into standby mode. i woke up 7 hours later to find it on 9% battery! on my old XDA II, it would lose maybe 1% battery overnight with flight mode on. I'm going to keep testing this though.
as for the rom, as far as i know, rom = flash. the pda2's only have 64mb of rom or flash, whereas the xda IIi's have 128mb. as far as i can tell, this is the only hardware difference between the two devices.
hmm.. i just checked out the PDA2 website, and you're right, it says 128mb of rom. i've read elsewhere that it was only 64mb of rom tho, and thats what it says in my device information page as well... and i could have sworn that the above page used to say 64mb of rom..... very strange

The perils of assuming the same radio stack works correctly across the globe with all operators!
Case in point - Xda II 1.66 rom worked brilliantly in UK, and sucked the battery dead in 8 hours in Germany. Why? because the german network had different settings for paging the handset
I'd say you've got a valid case to:
- Tell Imate to f*cking fix the problem
- Downgrade the Radio stack to another build and see what happens
:wink:

'scuse me for butting in...
Guys
I've been having really big problems with my battery too on my XDAIIi. You might care to look at the log I kept of the battery over the course of a day here

well i had flight mode ON, which means the aerial is turned off.. so i don't really see how the operator settings will affect it...?
i checked how i went last night, again turning the phone off (flight mode on), and sleeping for about 8 hours. my battery life had only dropped 3% which is much better, it went from 81% to 78%.
its an interesting thought about the paging settings though, when i finally sort out my login to the i-mate forums, i may have a look around for that.
stevep, yes i remember reading your thread a few days ago.. unfortunately it doesn't seem like you came across any sort of solution..

battery XDAIIi
Hi all
You're right, there was no solution. I had the device replaced three times and the battery twice. I can conclude that it's definitley a feature of the device. I don't what's draining it (nor do o2). I had the problem escalated at o2 and although they were very helpful, they didn't really come up wiuth a solution, which is disappointing! My main issue was mostly about how long it took for o2 to admit it's a problem. The normal 'change this', 'hard reset', deinstal/reinstal everythig' etc etc just seemed to be their way of 'getting off the hook' (sorry o2) and concluding that it must be something that I've installed on the device
I was getting to the point of thinking about reporting it tomTradining Standards here in the UK because 8 hours or less (to me) doesn't make it 'fit for purpose'...but in the end I didn't because it felt that it wasn't a strong enough case to argue. Now I just carry a spare charged up battery
Steve

i work an office job, so i have mine cradled most of the day, but the weekends is where it gets tested. we'll see how it goes this weekend. on the xda II i usually had about 30% battery left on sunday night.. last weekend (the first weekend i had it, i got it the thursday before) it barely lasted one night.

IS THERE ANY SOLLUTION??
So whats the solution? ....This much less battery time does,nt serve the purpose for me ....i always have my nokia handset with me bec pda2 battery goes dead in 6 hours when i am at work...i am seriously thinking to sell PDA2...it would have been better that i should have purchased PDA2k.i post a query to imate technical support they replied that give a hard reset to ur device and see ...but nothing happened..the guy said he is forwarding my query to technical deptt lets see what they say....
In short i am really disappointed after spending so much money what i got?...if the battery time is less pda2 is of no use for me.

The solution
Hi all - After long conversations with O2, I conclude that there is no solution (apart from always carry a spare battery). I'm really disappointed too! More so, because O2 constantly said my PDA was 'not right' and they kept swapping it out for anew one...

just a thought, have you turned turbo omode on? because that will definetly suck the battery?
also, turn down the backlight settings....

Battery
Hi SouthernMan
Yep Turbo off and backlight set to minimum (plus all the other tweaks that drain the baterry are 'off' or set to their lowest

right now im hoping they're going to release a new ROM that will magically fix everything.. because i can't see it as being a problem with something we're doing.. it must be the device.

Battery
Hi OmniWolf
I agree 1000% That's what I kept telling O2, but they insisted
1. it was the device (changed it twice, made no difference)
2. it was the battery (changed it three times, made no difference)
3. It was some software I was running (took all progs off one by one, took ages, made no difference
((
S

well hopefully they'll get enough support calls that they start looking at the problem seriously

I REALLY hope so! it's a great device...but I can't get through a business day without having to recharge it. Mainly that's not as problem, but just occasionally, I have to work a day when there's no access to any charging facilities...and if you couple that with going out after work for a few drinks, the PDA is completely dead by the time I get home
I found that mine was draining at a rate of 8-10% per hour

Dear All,
Battery usage time is really one of the big concern for heavy duty user.
But O2 seems don't have any solution for the buyer. Buying a spare battery seems to be the only one solution....

I know you recommended buying a spare, but a more powerful battery that get you through the business day is a better solution in my book!
Hey I saw from Blue Angel thread you guys (Mugen) have battery for IIs.
So.... do you have higher capacity batteries for XDA II and IIi?
From myxda site I think they use the same battery.

think i might invest in sprite backup actually..

A disapointing end with pda2
Atlast after getting no reply from imate customer support(they just said give it a hard reset which had no effect on battery life) i sold my pda2 which had 4 hours of total call time at a loss of 180$...there is no big market for pdas in pakistan.
I was never expecting a well reputed device costing 800$ with such a major flaw... imate and o2 should be questioned in court y they bought a pda in market with a major flaw.

OpenTouch problems!

Hey everyone, I hate asking questions in forums...i never feel i did enough searching, but i think i did enough this time.
I have been using OpenTouch Biggy v3.0 for quite sometime now on my wing. It runs pretty well, but i had an issue where my battery went from lasting close to 2 days, to lasting half a day or so. My phone habits didn't change nor did any settings, So i reinstalled and the battery went back to lasting 2 days again. But when i was researching i seen that OpenTouch v5.3 biggy was out so i installed that version about 3 times. Each time the top bar is missing and will not show. So instead i installed v4.0 biggy and my battery is back to not lasting very long. I really enjoy using Opentouch, I have tried the others but always end up back with OpenTouch. Anyone else have this problem?
Another thing i would like to know and i might be wrong here(i haven't run OEM Windows mobile in quite sometime) But is there anyway to get the original AIM app from the stock rom? I want all the Biggy apps to though. I do have Palringo installed and have been using that for a couple weeks now. Not sure if i like it though.
Sorry if this post is messy or unclear im working off about 3 hours sleep and need to get to bed!
Thanks for any help!

here is an example of my battery problem. I unplugged my phone at 6:14am made maybe 3 phone calls equal to about 10 minutes total. Used the internet for about 20 mins and now at 11:21am i am at 42% battery. With OpenTouch v3.0 i could of tripled that and tonight around midnight when i would of plugged my phone in the battery would of been closer to 70%.
Would love to get some answers on this, if anyone knows any settings i can change or what not.
Thanks.

You sure it's not a bad battery? They have had a lot of problems with the Dynapack batteries.

I found an article saying that T-mobile and HTC are replacing the dyna-pack batteries. but my phone doesn't seem to over heat. Also, if i put OpenTouch V3.0 on my Wing the battery will last longer again. I think its something in the software settings.
Here is a link to an article i found http://www.wmexperts.com/articles/tmobile_replacing_overheatable.html

I think that ttran made Open Touch 5.0 and higher have the radio that gets better reception, but pulls more power, but I don't think it was supposed to pull that much power. When I tried the 5.0 series, I didn't notice a drop in power at all versus 3.0. Hmmmmmmm.

Well with the v5.0 i am not sure if the battery dies quicker or last longer, i don't get a top bar after installing it. So when i installed v5 i kept it for an hour tops and reinstalled 3 times in a row, then went back to v3.0 or v4. My problem seems to be with V4.0. I like the looks of it and would like to keep it. but i can't deal with charging my phone 3+ times a day.
I did see a post that says some people wanted to keep the radio from V3 on V4. maybe ill try installing that and see if that fixes the problem. I will let you know the outcome.

You could install batterystatus so you can see the remaining power.

I can see the remaining power, that is how i know when the phone will need to be charged. What i meant was i have not left OpenTouch V5 on my phone long enough to see if the battery lasted longer or not.
When I get home i am going to put the V3 Radio on my V4 phone. I will let you know the results.

Ah, I gotcha....Yeah, I'm running v3 radio and it seems to be the best out of the bunch for me.

Well i did more research and found some Radio upgrades and what not. I figured why go down a version on the OS when i can upgrade the radio version. OpenTouch V4 comes with Radio 03.12.90, So i updated to 03.18.90. I will just have to test this for the day to see how the battery life is. From what i read it was about 60/40 of good/bad. I guess if this radio sucks as much juice as 03.12 i will just try going to 03.21.90 and what not.
Now to figure out why the topbar wont show up in OpenTouch V5.3 for me. I love TTrans roms! I'd like to stay up-to-date with him. =(

I think it's a file in the startup. It might be cleanstart, but I can't remember for sure. I think if you slide the keyboard out, it comes back, but I remember reading about this somewhere...

Well i gave up with the radios and put in OpenTouch v5.2 org. Then i extracted the NBH file from the new release from Tmobile and flashed that to my phone. It seemed pretty quick and what not. But i ended up saving the OZ IM program file and flashing OpenTouch V3.0 again and added the OZ IM from the stock Tmobile rom and it actually opens, but it wont connect. Oh well.
I am looking into cooking my own roms now and have followed a guide to create my own OEM. So maybe ill become one of the known cooks =)

Problem
I have a problem, my cube doesn't work like the way it shoud btw i have open touch 5.0 , so like the regular cube to open it u slide ur finger from the bottom to top and it pops up but not in mine, i have ramdonly slide finger in many direction multiple time for a while before it comes out, so please tell me is there something wrong

I ended up installing OpenTouch V3.0 last night to test the radio in it. Well my phone was unplugged fromt he charger this morning at 8:15am and it is now 4:17pm...the battery is at 72%. The radio version is 03.07.90, not sure if this is exactly what is making the battery die slower...but my reception is not as good as before. I am going to upgrade this Radio. I also downloaded Aserg's newest rom, I have never tried his.
As for the cube i am not sure. I have never used it. I will give it a shot this weekend and see if i can help ya out.

thx looking forward to it

I am surprised that the 3.12 radio drains your battery that quick. I have been using it in the OT 4 and 5 versions and now in Touch-IT touched by vista and I average 2 days of battery life before I charge unless I have been heavy on the internet usage. I have heard that the 3.18 and 3.21 radios drain battery life quick, but I haven't read too many complaints about 3.12. if you haven't tried any of the Touch-IT roms, give em a try, they are probably the most stable roms I have used yet, although I noticed for some reason with Touch-IT touched by vista my reception doesn't seem as good even with radio 3.12. I don't understand that....

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.

Battery Life - WinMo 6.5 or 6.5.x

So I am thinking of making the switch from 21xxx to 23xxx and I read somewhere that I will see a increase in battery life by doing so while staying with the same cooks roms.
Does anyone have an opinion on this? Will the newer windows builds really help my batter life assuming the same usage throughout the day???
Thank you,
Jeff

I'm using WinMo 6.5 and as for right now my phone has been running for 3 days already with 40% battery life.

Jeff, I'm was the energy 23138 sept 23 standard rom and 2.14.50.x radio. i was getting anywhere between 24 and 36 hours on a standard size battery. I am a heavy user and when i'm at home my wifi is always on, i surf the internet a lot and if i'm out i've normally got the music player going. I also have the facebook tab updating every hour as well as my location. I also use the gps quite a bit.
So i would say the battery life is good but i can't compare it to 21916 as i have never used that series of builds and it's been a very long time since i used a stock rom, so again i can't compare.
My advise would be to try it out for a few days and see if you notice the difference but i have to say i am very pleased. I've just finished flashing and configuring 21619 sept 24 so it will be a couple of days before i can get a comparison between 23138 and 21619 (as you will have seen from the enrgy rom thread these are both 6.5.x builds) but i'm not expecting much difference considering that they use the same drivers from the 3.14 tmous base and the radio hasn't changed between the two.
A plus point though, seeing as you use the energy roms, is that xda_uc will still be able to import all your settings if you go for the same "flavour" rom i.e standard for standard or cht for cht (unless you pick the new cht2 builds then your cht settings are not compatible)

Can someone tell me how this is possible? I've had my HD2 for about 4 months now and if I don't charge it daily it's dead the next day. I'm using the new 2.14 radio and Miri HD2 WM6.5 (21916) ROM V 19.1. I have Exchange and weather on auto update and everything else is on manual update. Any pointers is a big plus. Thanks.
BTW I've tried the 23138 but I can't stand the over-sized buttons on the bottom. It's just absolutely hideous to me so I have no idea if it gets better battery life.

Extended size battery (the one that needs the different battery cover), auto disconnecting data connections, and not really using it very much at all

thanks guys for your reply, man it sure sounds like I am sucking as far as battery goes, my usage is a fraction of yours and I can barely get 20 hours. I think part of my problem is that at work, I have poor service, going in and out of coverage as I walk around the building. I have to turn off 3g and I barely have edge. I am currently trying duttys cream de la cream now 6.5.x to see if is any different. man, if I had your battery life, I would never flash again! I have latest radio, tried many, and the 3.14 rom.
I will let you know how this one goes.

I really don't believe some of you about the absolutely ridiculous battery life. Especially if you are heavy user, no way! I've seen lots of HD2's (different ROM's/Radios/battery charging methods) and I want to tell people on this board that they don't need to be worried if their battery is dead after a long working day with heavy use. So, don't believe too much fairy tales and enjoy your wonderful phone.

It does seem a little crazy huh? I hear that some Iphone users can go three days with pretty heavy use and a few that I have talked to say that thier iphone can barely last 10 hours. There seems to be a ****load of variability in current consumption amongst all variants of smart phones.
I would just be pleased to get from 5am to 11am with moderate use, without having to buy that brick battery with the built in kickstand.
I will give this current rom a week to see how the battery settles down, ignore the sig, it is the Dutty CDLC V17 with the 2.14 radio.

WP7 Battery Drainage Vs. Radio Rom

WP7 Battery Drainage Vs. Radio Rom:
After searching in Forums, I Found that most of us (WP7_HD2 Owners ) have a great issue with battery drainage.
I also found that some of us tested radio roms and found that it affects the drainage directly but not the same way the same version did on WM6.5.x
SO I wanted to create this forum to brain storm and try several radios and check what is the best for our Beloved HD2
I will post and edit the best radios based on your reviews so more you post results more we will get clearer image of what's optimum:
So Based on what we experience ; Radios are sorted Best on top:
1- Radio 2.12.50.02_2
2- Radio 2.14.50.04
3- Radio 2.15.50.14
I know it depends on your network provider also, but At the end it's kind of trial and error forum, we get help from each other: there is nothing certain 100 %.
Rest will follow...

Maybe radio 2.12.xx.xx should be tested also. It is a 576mb enabled radio also.

i've tried 3 radios so far
2.12 is the best, and 2.14 and 2.15 are very similar
i am testing 2.10 now
im using htc hd2 t8585, not tmous

i am using the 2.15,,works normally,, not bad,,but neither remarkable.

Managed to pull 30 hours until recharge with moderate usage on 2.12.50.02-2 radio. UK Virgin mobile' s best radio I might say when it comes to batery drainage.
Sent from my HD7 T9292 using Board Express

I have radio as 2.14. Would like to know whether the radio 2.12 is better ?

Wrong forum, this is is development not Q&A/General

Doesn't location also have to be taken into account? I understood that a radio that gives great performance in the UK could be terrible elsewhere and vice versa.
I'm not suggesting that this thread isn't a decent idea, just that users should also post their country of use.

I tried WP7 with radio version 2.15.50.14, the battery lasts two days, vs windows mobile 6.5, 5 days.
But my opinion is that the problem is a bug that allows the use of gprs/3g link cause some sort of continuous, although the 3G connection is switched off.

Im using Radio 2.12.50.02_2 simply because I seem to get a better signal with it. Ive not noticed much difference in the battery life than when I was using Radio 2.15.50.4

Just added it here because it discuss the topics mainly accessible through development, and want most of us to reach it....

I have switched from radio 2.15 to 2.14. and I see improvement in battery life

Sorry if this is a bit off topic but it's just something I experienced that might be found useful....or I may have a freaky battery
Could the problem with the battery drainage could be related to the battery state when WP7 was installed?
I installed it on my device when the battery was half charged and I was only getting 1/2 a days use before it died. When recharged under WP7 it would take 1hr and only last another 1/2 day...but.........I installed android and am now dual booting WP7 and Android.
I ran the battery out using Android and recharged it under Android to 100% charge. Since doing this WP7 takes 2 hrs to charge instead of 1hr but the battery lasts all day with between 5%-15% remaining after 12 hours.
Maybe WP7 checks the battery state on install and assumes its fully charged when the device (HD2) is first powered on and incorrectly calculates the maximum charge!?
Just a thought.

I believe you are right. For the first time did y HD2 chage under wp7 and i noticed that the battery did not last half a day. I usually charge my batteries through an external phone battery charger (have 3 batterie which i rotate).

I am trying 2.14 in London Uk. So far better than 2.15. Will try 2.12. I remember there was one radio in particular that was FAB for battery life but so so for reception. I will try to find out which because for me battery life is more important. Could have have been evem 2.12. Will have to search the other forums.

You might be on to something here! I charged my phone to full capacity while downloading and waiting to install WP7 and my battery had been good. I even believed that it holds better than with android builds on NAND or SD. Lets investigate this, please.

Radio 2075027_2
Ok I managed to find the radio that gave me excellent battery life under Windows 6.5 rom = Radio 2075027_2. I reasearched my old posts in another forum.
I have installed it fine and will test out over the next couple of days and report back.
If anyone else wants to try, the radio is in link below:

Remember, just a warning for everyone.
If you use a 2.07, you want be able to boot into Android (if you dual boot using MAGLDR SD card).
Android needs 2.08 and up.

i tested 2.10
it is a little bit inferior than 2.12 =) but it is still great
