I'm weighing value of signing up for another 2 yr. contract w/ATT for the Kaiser ( ATT 8925) to replace my 8125 wizard. I'm reading and hearing two 'issues' with the Kaiser.
First is that the speed of the 3G network does NOT amount to that much improvement in web page display compared to the wizards. This is reputedly due to the latency of the network/device combo. A friend who has the Kaiser says that he doesn't see that much improvement in the display rate compared to Wizard.
Second, issue is battery life. My Wizard can typically go three days between charges...depending on usage. I am hearing that the "user experience" for the Kaiser is more like ONE day between recharges.
I would be interested in anyone's experiences with the Kaiser and especially anyone who has upgraded from the Wizard.
BTW, I'm pretty pleased with Wizard and am not all that anxious to upgrade. I've taken full advantage of this great XDA site to upgrade my Wizard to WM6 and add LOTS of applications.
Appreciate your comments.

Wizard (Cingular 8125)
Diamond 3.0 ROM
Radio 2.69
I've had my Tytn II for about 6 weeks now, having upgraded from a Qtek 9100. I can't address the 3G issues, as I don't have a data plan -- I use WiFi for net access. Having said that, I don't see a major speed difference when in IE.
Battery life is a bit shorter, especially if you use GPS or 3G -- those use lots of power. Since I don't use 3G, I'm finding that I can go 3-4 days without a charge, roughly the same interval as with my old Wizard.
I've had my Kaiser for a couple of weeks now, and upgraded from a Wizard (which I'd updated using this site to include WM6 etc.) and so far I'm fairly pleased.
The web pages don't seem to be much of an improvement in speed, but I think that's more down to PIE than the device. Try downloading a file over 3G and compare it to GPRS and you can really tell the difference. Opera Mini (beta 2 I'm using) is quicker on the Kaiser than the Wizard, and exits properly (which it didn't on my Wizard) and is a lot better for performance than PIE.
The battery life I still haven't figured out. The first charge lasted from 8pm Tuesday to about 11am Friday, the next one til 2pm Monday, and then I can't remember whether I charged it between then and Sunday (but I'm guessing I probably did). So it seems to be lasting about 2-3 days at the moment, but it all depends on usage. My Wizard lasts about 4 days on average, so it's a little bit less, but I'm still only just getting to grips with the Kaiser and haven't really touched any of the backlight settings or anything like that, so I'm sure I could eke it out a bit longer if necessary. Overall though, I would say the upgrade from the Wizard (features, esp. built-in GPS) outweighs the uncertainty with regards to the battery life.
If you're used to charging every few days, or you're not really too bothered about being "green" and just charge your phone whenever it needs it, I think the Kaiser is a worthy upgrade from the Wizard. Unless you want to wait to see what other devices come out next year, or at least are rumoured early next year, before signing up to a 2 year contract.
I'm in a really weird situation. Last weekend I've updated my raphael's ROM from the stock one to the localized one (same version tho). I didn't have time to install the apps what i need, so i did it on Monday. This means my phone was many times hanging on the usb cable because of active sync and so. When i finished the installations/setups i decided to charge the phone to 100% (it was already charged like 80%). It was like Thursday when i was wondering, why my phone still showing 51% of charge level. I checked the last sync date (and it showed monday) so i was ensured that that was the last charge also. Today (Saturday) it has still 23% remaining DDD Since Monday I had like 30 minutes or so talk time, 2 hours of music playback, several messages, a little bit of wifi, an hour of solitaire and i messed for a while with some programs (setting up after the rom update). I never turn the phone off during the nights. I know this isn't a hardcore usage, but still weird that the battery is still holding up. I bought the phone right after the European premiere (19th of august if i remember correctly), and i can't recall a longer battery life like 2-3 days with the same usage like this week.
Did anything like this happen to anyone else?
I'm curious what will happen after the next charge
I've had the same experience installing the ROMeOS² rom; battery life had suddenly increased from ~1 day to 4-5 days. Can't explain why, but hey, I don't really care.

May I know which version of ROMeOS you were using?
Thanks
hi!i have standard HTC rom. Maybe someone can deliver list of running services and background apps in ROMeOS². I will compare with this in standard rom. Maybe I kill some services and it will work longer ?
This one:

List of services is in the post, all you had to do was look in the ROM section.
This week I upgraded my S710 to WM6.1 (the current Gonzo ROM) and overall am happy but today I have noticed something very odd.
I normally charge my phone on the dresser overnight and then take it off charge around 8am at the start of my working day. I run push email from my corporate exchange server between 8 and 8 and make many calls. By the end of the day (I normally go to bed and put the phone back on charge around midnight) the phone has maybe 45% battery left.
We today has been a typical day and it is 11pm yet the phone still claims to have 79% charge left. Yesterday was much the same.
I have the tornado software ramped up as well for a faster clock speed.
So either WM6.1 is a lot better at power management, WM6 had a big problem or the software is miss reporting.
Has anybody else seen this?
PS
If my new S740 is this good at power management when it arrives I will be very very impressed.
its a programs issues, with the oficial spanish ROM i got this problem, when i open camera or windows live messenger and pass to second plane, even with the wifi off, the programs consume a lot of energy, no idea why, with gonzo "mona liza" ROM my battery life its very long, even with a lot of wifi use, camera and msn open always, i think WM 6.1 work much better with the resources, Regards
I noticed the same thing today
After 6 hours of idle it used 1%, normally it consumes about 5-10% in that time on doing nothing.
I'm happy with it
LoL I'm using TPC and I'm used to those situation My phone stayed in idle for 3 days and the battery was about 57%...the I looked for composing an sms and...tadaaaaa...LOW battery 10%...so be aware that that is not a good method for measuring battery life.
Yes i was already afraid this would happen.
Ah well, i'll test it on my vox now too will post when i have information.
how long do you get on a single charge? i would like to buy one of these devices and use Exchange push, but if it can't last the whole day, forget it. That was why i ebay'd my iPhone. i would like a device to last ALL day. can the Fuze do it?
that depends on what else you doing with the device, long phone calls etc, if all you were doing was push email, you should be fine
well, what about if i talk for about 20 - 30 minutes per day....
what if i watch a handful of youtube videos....
what if i browse the net with WiFi for 15 minutes....
i am just asking for someones actual battery stats.
More than likely, you will not make it through the whole day if your watching youtbue videos, talking on the phone and using WiFi. Add GPS to that mix and I promise you it will not last more than a few hours.
I flashed my TP to ROMeOS 1.40 with radio .28 and have absolutely no problem getting two days with normal usage. I have Exchange syncing as items arrive. If I added some wifi and video as you suggest, it might struggle to get two whole days without charge, but certainly no problem with one day's heavy usage at all. And "heavy usage" would include some TomTom - a big battery drain.
perfect. exactly what i was looking for. thanks. i'm on my way to the AT&T store now.
I've had mine a few weeks now. It has Exchange push mail on all day(syncing as items arrive), and I'll make a few phone calls. I get about 2-3 days out of it doing that from full charge to almost empty.
If I use TomTom it's massively reduced.
As a project in my Statistics course we are asked to develop and carry out an experiment. Rather than do something conventional I felt pressed to do something that would actually be useful to myself and potentially the community.
-A comparative experiment of radio stacks' effect on battery usage will be done.
Now I realize there are many confounding variables that effect battery drain that are equally as important, location, usage, brightness, ram load and user use habits : however for the sake of the experiment I wish to see for each user how their battery drain changes based on the radio in their area on their usage. Because each users results will be directly compared with their own many of these confounding variables will be minimized as much as possible with such a short time frame to test.
The experiment will call for any available HTC Touch Pro users (World wide) starting May 18th to flash the official radios, each day trying a different radio and tracking the battery drain.
The current plan is to use the official released radios at
(Including the ATT Test rom radio but not the newer 1.14.25.05 due to issues and bugs confounding the results even more)
- Radio - Day of Trial - Date - My Resulting Percentage at end of day
-1.12.25.19 - Benchmark / Comparison test - May 18th - 40% at midnight
-1.02.25.11 - Day 2 - May 19th - 6%
-1.02.25.19 - Day 3 - May 20th - 15%
-1.02.25.28 - Day 4 - May 21st - 45% (gasp)
-1.08.25.20 - Day 5 - May 22nd - 3% (Battery Change out at 10:30pm) 87% on battery 2 - total - -10%
-1.01.25.16 - Day 6 - May 23rd - 14%
-1.02.25.32 - Day 7 - May 24th - 5% (Battery change out at 9:30pm) 51% on battery 2 - total - -44%
Just got a Touch HD - Had to take 2 days off the trial to play with the lovable device.
-1.02.25.27 - Day 8 - May 25th - (May 27th) - 3% (Battery Change out at 10:30pm) 98% on battery 2 - total - 1%
-1.02.25.31 - Day 9 - May 26th - (May 28th) - 43%
-1.11.25.01 - Day 10 - May 27th - (May 29th) - 10%
- End of Trial - For me -
I will wait a while to collect all available data from testers then perform the statistical analysis.
Download Radios Here
Conditions for testing:
Because each user is unique in exactly how they use their devices, 3G / 2G, Wifi, Bluetooth, GPS, I only ask that the usage be relatively consistent throughout the trial. As long as you are consistent with the other things draining your battery we can see exactly what it is that radios drain.
Each evening anyone willing to participate in the experiment will flash a new radio and track the battery drain over the following day.
In order to track battery usage, the performed method will simply be recording the remaining battery life percentage at the conclusion of the day. (usually a selected time by the user) This is due to no battery tracking application freely available that efficiently tracks battery levels without interrupted normal usage or battery life.
I apologize for the short time frame that has been created, however the project was developed months ago, yet the teacher simply dumped it on us to get the actual experiment done next week and I am truly hoping I can stir up enough interest and enough volunteers to get the data I need.
Please post if you have any interest in the project, wish to volunteer, or have a suggestion for which battery app to use.
I need volunteers and this is information that is helpful to everyone, so please take part and please help out.
If nothing else, I will post at least my own results to this little experiment.

Started a day late, hope it's not a big deal!
I second the attendance on this
Tell me where to locate the radios and where to submit results, I'll be there. count me in.
Thank you for the immediate support. As I said in the post this will attempt to begin Sunday evening where you will flash the first Radio and continue Monday like normal, then at the conclusion of the day simply record the remaining battery life percentage.
Try to keep the start and end of your day consistent and ensure devices are charged to full every night. This may mean simply recording you battery level every night at 8pm rather than waiting until you head into bed to keep the timing consistent.
I hope anyone interested signs up as well, as the more data the better.
Anyone can sign up for the trial, if they have a Touch Pro or a Fuze, doesn't matter. In fact they can even join up halfway through, they will simply need to continue the trial to include the missed radios.
Tomorrow will begin the first day of the test, as the comparison test we will begin with the radio that is considered to be the best by many. The ATT test rom radio. 1,12,25,19
All radios can be downloaded from the radio thread

This thread includes downloads for all radios and flashing instructions.

I am willing to participate in the survey...Should we recharge if it doesn't last the whole day and document the time it went dead?
Yes, if your device does not make it through the entire day on one of the radios. document the time and either recharge to full (if not full record the percentage) or swap out batteries (to a full one) and continue like normal. then doccument the remaining percentage at the end of the day.
Tomorrow begins day one of the trials, so if we could all flash to the ATT Test rom radio
1.12.25.19 and charge our devices, we can begin this whole thing tomorrow morning!
Simply post your daily results in the thread, send them to me in a PM, or find me in the IRC channel #XDA-Devs under the name NonPlayerChar and message them to me. You can do this after each day, or keep a record yourself and send them to me whenever you find it convenient.
.. wish i could participate
buti cant even flash rom's even though i can tweak everything else on my phone. and i carry two batteriez... im definetly gonna keep reading this topic.
My first two days results
1.12.25.19 Day 1 May 18th 62% -- 12hr timeframe
1.02.25.11 Day 2 May 19th 47% -- 12hr timeframe
I have to add if you noticed that I only kept the phone on for 12hrs as I turn it off at nite before I go to sleep to avoid the ex-wife from texting in the middle of the night. If you would like me to test for 24hrs. please let me know and I will find a way.
Both test periods were with push email enabled (HSPDA on) and identical usage.
I have the newest 1.14.25.05 and no issues here, i can report if needed
Great results so far, I would like thank everyone who is participating.
Fjmora992000 : Great results - No your time window is perfectly fine, as long as it is consistent.
Mine goes from about 7am to 12am the next day, so a 17 hour window.
I am seeing similar results with 1.02.25.11 compared to 1.12.25.19. Although, if the drain continues as expected, I may be exactly 0% at midnight.
Bowdowntozoltan : Great to hear it, I may try out the new radio soon as the trials end. If you would like to participate in the trials, any effort would be appreciated, however for any data to be relevant you would need to try the other radios on your device as well. This would be much appreciated, as anyone knows, a large sample size is ALWAYS* better. As I said before you can simply continue as scheduled with the planned radios then make up the previous radios after the end of the trial.
*(A large sample is almost always better, except for when a sample is more than 10% of any given population... this causes conflicts with independence however... we will not get into that)
Final results.
Sorry for the delay, I've been working a bit and trying to settle into the new routine. The test was a gruesome one, many variables led to an ackward result. I think I'll redo test again and see what comes of it.
1.02.25.19 - Day 3 - May 21st 40%
1.02.25.28 - Day 4 - May 22nd 47%
1.08.25.20 - Day 5 - May 23rd 55%
1.01.25.16 - Day 6 - May 24th 45% very unstable
1.02.25.32 - Day 7 - May 25th 38%
1.02.25.27 - Day 8 - May 26th 53%
1.02.25.31 - Day 9 - May 27th 60%
Thank you for the results.
I had some terrible instabilities with a few radios myself, causing horrible lockups and simply all around poor system performance, however I've found it best to simply work through them.
