WM5

Hi all, I am all confused about which Windows Mobile 5 ROM version to load to my Blueangle. I read forums about these different ROMs but I got more confused. Which ROM do you reccomend?

Helmi_C AKU3.2 v1.3 beta is currently the best one out in general.

Can you tell me more about this ROM's performance? What do you think when you compare it with wm2003se? Do you think it is worth to upgrade to wm5 from wm2003se? Thanks.

I really dislike alot of the early WM5 roms because I thought they were unbearably slow so I kept with 2003SE until about a month ago.
Then an AKU2.3 ROM was released which I tested and it was muc quicker than the previous offerings. I'd be willing to say Helmi's AKU3.2 ROM is just as quick as 2003SE is, and its prettier :lol:
It's definately worth considering about upgrading now.

Thanks my friend. I'll give it a try. Are there any features (features of wm2003se and my pda2k) that I won't be able to use when I upgrade to helmi's wm5?

Hi there,
I would like tyo download WM5 BA ROM, but I'm affraid, there is no posibility to download any ROM from ftp server.
Threre are some problems with connection. Speed is very low.
Dowloading stopped after 10 MB...
Please tell me, how can I download ROM....
Thx,
MCS1

My experience with WM5 was not so good. It's so much slower than 2003SE! I recently downgraded and it's like night and day! 2003SE feels about 100 times faster than WM5 - especially all phone functions! It takes several seconds until a WM5 BA starts ringing, picking up takes eternally, so does hanging up, etc. Everything you do during normal use is much slower as well. It was really annoying using my BA with WM5, and now, back on 2003SE it's fantastic again.
If you don't desperately need any of the new functions of WM5 (like stereo bluetooth headsets and push email), I strongly recommend sticking with 2003SE!

Martin

Hi, I just recently converted and I am loving it all the way. Go with Helmi's AKU3.2 ROM as it has given me very little problems, other that the need to just make sure that I read and understand the guide first.
I did find the phones operating speed somewhat slow, but then that is to be expected from a installation that was not meant for the phone. Same thing happens when you upgrade a PC witha new OS and it goes a bit slower. But what you can do is to help it a bit and what I did was to spend around £14 on XCPUScalar and overclocked the internal chip from the standard 400mhz to 530mhz. It is so easy to do, all you do is to install the application and then slide the slider to the required speed. It does mean that my phone battery does go quicker, and I have been trying out different scenarios and whereas during normal use, ie 45 minutes of mp3 listening in the morning and then again in ther evening while on journey to work, and around 10-20 calls a day, the battery used was around 75-85, now it completely drains my battery unless I use my spare.
The best thing to do is to invest in a USB data cable which charges the phone at the same time and even if you have a laptop, you can still charge the phone during the time that it is in the cradle.
The XCPUScalar does have a dynamic speed changing capapbility which basicaly changes the speed depending on CPU percentage used, but I found it slightly sluggish to kick in and just so much easier to stick it onto the 530mhz and just take my spare battery with me.
Now that I have it at 530mhz it works even better that I had hoped, all the functions and compatibility and even works faster that my previous 2003se.
Be careful thought that the process of upgrade may take a few times to get right, so make sure that you have either the whole day to spend on the upgrade or you have a spare phone to hand.
Extra tip, and very important, dont use a external USB hub to plug your phone as when you come to upgrade it gets stuck on the OS Upgrade screen and like me you will have a heart-attack until you figure out what the problem is...
Hope that helps.

Thanks for all answers. I upgraded to Helmi's AKU 3.2 and happy with it. I agree that phone feature gets slower but I can live with that. Other features are working normally and are not slower than 2003se. Maybe using XCPUScalar speeds up the machine but are you sure that using this porgramm will not harm the cpu? If yes, I can also try it.

afaik intel's xscalar cpu's were designed to run @ higher speeds and designed to be scaled up and down to save battery, but microsoft in thier infinate wisdom decided they couldnt be arsed.
So long as you dont enable the 'show frequencies above 500mhz' then afaik your phone is in no danger, however i would recommend enabling that and setting max speed @ 530 (but scaling) as sometimes thos extra 50mhz really help. meyself and a lot of other people have had no problems with it at this speed (i know black6spdz runs one of his @ 590mhz, and thats not dead yet :wink

hmmm, so I will try it

I find an IME switch problem： After I install CE-star 2.8 r1, it will installed two IME, one is chinese "chaji", the other is "chinese hand writing".
there have problems when I switching in those IME. it takes no effect. this problem appears int CE-star 2.8 r2 also

Battery Life in WM6.1

I've been seeing sporadic posts in different threads about battery consumption in WM6.1 ROMS.
Well, it turns out that since starting to use WM6.1, I've noticed a dramatic decline in my battery life. I can maybe squeeze out a day of use with minimal use. If I use HSDPA / Voice / WiFi - forget it, I get 1-2 hours before the battery drops to nearly zero.
I used to get much better life out of my battery before.
I tried playing with different ROMs, then different Radio version - to no avail - battery life sucks.
Any tips / ideas / comparisons on how to get reasonable performance with WM6.1 or is this just my battery having issues?

I think this would be more your device...
To check this, go back to your manufacturers ROM, and see if the same still happens. Also try this test with no 3rd party applications installed.
Poor battery life is usually cause by either:
1) Applications using 100% CPU
2) Faulty ROM
3) Faulty Phone or Battery.
If you're tried multiple ROMs, I'd say you can rule out #2.
I get around 2 1/2 days out of the stock 1350mAh battery on my hermes.

Hi
ygeller , i had some battery life problems with my hermes and i found on another thread some ppl saying to first flash the ATT rom RUU_Hermes_CINGULAR_WWE_3.62.502.3_6275_1.54.07.00_108_UOOS_SVN05_Ship
and then the cooked one. That worked wonders for me, the radio version 1.54.07.00 is the best i tryed so far for battery life and network stability.
I'am using the latest PDAViet rom and no problems so far, with battery holding for 2 to 3 days with normal use.

Please try another radio, i used always the newest en I got the poorest battery performance! Now I use 1.47.30.10 in combination with PDAVIET roms and now my battery holds a day of 2/ 2,5!!

I have issues with charging too with my phone never charging full no matter how long i keep the charger on it get's stuck at 80%...
But good news is that I've arrested the drain now i flashed the PDAcorner pr0 V3 yesterday and through the entrire night the drain was less that 1% but it hasn't solved the drain if I use voice/data cause an 11 min call had my battery coming down from 63% to 16% ..
I guess i am gonna try and flash the stock ROM as compumad says..
I guess at least the charging issue is due to faulty ROM ( i hope)..
Thanks guys for input..

I agree that I get better battery life with the 1.47.30.0, in addition to aquiring a signal faster. The BIGGEST fix for me however was replacing my year old battery with a good quality Li-ion battery. Now I go a full day with hardly any drain using anybody's ROM, of course YMMV

I am having the same experience. I tried several WM6.1 ROMs and they always drained the battery within 1 day. I am back on Schap's ROM now and I can work for up to 3 days with HSDPA and BT on. About 1 month ago I returned my Hermes because of a defect and HTC replaced the complete inner life of my phone. So this can be compared to a more or less new Hermes.
As a comparison, I recently received a Wizard as a gift and flashed it with the WM6.1 ROM of SNN and believe it or not, the battery lasts for amazing 5 days! And that is with GPRS and BT on!
So, are we talking a major device issue, a ROM issue or is there something I'm missing here?

I've been on the current Shamanix`s WM6 Ultimate v2 FINAL [SuperStorage] ROM for a while and indeed the battery drains very quick- I've had to schedule Exchange email to be on for 2 hours now but a simple 20-30 min voice call drains the battery by about 30-40%!
I was on Schap's ROM but was waiting for his latest update. Will have to consider another one.

I have also had the same issue as people here with the battery running down very quickly.I did try going back to schaps 4.31 but did not seems to make a difference anymore.Will try going nack to standard rom and then changed to cooked and post if there is any difference.

are u guys serious? 2.5days out of the stock battery?
my battery is a 1300mAH and i get a week and a bit on standby, constant txting wifi, screwing around, i get at least 4 days.
now that i have a 1650mAH i cant even kill it in a day (wifi bluetooth and gsm all going at the same time)
theres a 3000mAH battery coming in the mail, if im gentle with it it should last.... 0.5 months?

you need to resync your battery circuit, charge your phone till your phone cant charge it anymore, then drain it till you cant even turn it on (no lights at all), charge it up again and it should be reading correctly.
here is more info about Li-ion and Li-Poly charge circuits.
see subheading "Guidelines for prolonging Li-ion battery life"
http://en.wikipedia.org/wiki/Lithium_ion

I also had a severe battery drain with several 6.1 ROMS. My main culprit was caused my certain applications not closing properly and running at 50%-100% CPU. The main apps were Internet Explorer, Windows Live, Poutlook, basically network based apps. For some reason the app wouldn't show up as running. It wasn't until I got a new task manager that showed "processes" that I found the culprit. I would make sure all these processes were "killed" and my battery life lasted a lot longer.
I eventually went back to a 6.0 ROM, as I couldn't take all the problems.

Unfortunately, I've done that without planning. I am constantly fully charging the phone - then it drains and dies after a few morning phone calls...
This doesn't help...

OK. I am flashing the ATT ROM to see what gives.
Already it's been a chore. I haven't flashed stock ROMs in quite a while - had to extract the NBH file and use in with a cooked ROM wrapper to get it to flash.
Will report back with results.

Have Flashed ATT, then PDA Corner Pro V3. I didn't have much faith in the voodoo of flashing the official ROM to magically repair stuff - and so far I can't say that I've seen much change...
too bad...

You put PDA into bootloder mode and the flash, no need to jumpthrough hoops.
Actually the AT&T Official has repaired numerous bad flashes for me, is a lifesaver.

I have been a user of the stock AT&T WM6 Rom for many months. Before that, I had the stock Cingular 8525 WM5 Rom, and many of the cooked WM6 ones, starting with an early Black, a couple of Custel's, Sleuth's, and a few others. I now use personal derivations of the stock AT&T WM6 Rom that I have been cooking up over the past few months.
I have NEVER had good battery life on my 8525, with ANY ROM at all. Left alone, my battery dies after only a few hours. I have learned to live with this, always carrying a second (charged) battery, and I have chargers at home, at work, and in my car, in order to deal with the issue.
I must ask, when others say they get 2 or more DAYS out of a charge with "normal use", please define what "normal use" is for you.
My "normal use" includes checking 4 email boxes, one of them push, one at at 30 minute intervals, and two hourly. I use PocketWeather, which I have doing updates at 30 minute intervals for 4 locations. 1-calc updates monetary exchange rates daily. I make/receive only a couple of phone calls daily (yes, a BIG battery-killer), and I rarely receive text messages. No MMS at all. I utilize Bluetooth devices during my commutes in both directions, only use WiFi at home (another big battery drainer, but since I'm at home, it doesn't matter). I keep the IR port turned off unless I'm actively using it. I am on the internet with my device every chance I get, using the normal AT&T WAP access point with an unlimited plan.
I feel that with the amount of usage I get out of my device (especially Internet and emails), I can accept the poor battery performance.
But I am curious ... those of you who claim much higher numbers for battery life under "normal usage" ... please explain what "normal usage" means to you. I have never seen anything close to the numbers that have been posted by many.
FWIW, my two batteries are: 1 stock 1300mAh, and one is a Boxwave 1350 mAh. Both are well over a year old.

I'm forced to agree with pvs. I'm in a very similar situation: I use the stock AT&T WM6 ROM, although I've used a couple of other ROMs and Radios before this.
If I set my 8525 to auto-poll my 4 mailboxes every 15-60 minutes, I always notice a definite decrease in battery life. In the beginning, I'd get the "low battery" notification before I even left work late in the afternoon (this is after getting a full charge the night before). In between then and now, I turned off auto-polling. I couldn't get any new mail unless I did a manual send/receive...but my battery life improved dramatically; I could get nearly two full days' usage out of it before having to charge at night.
I was fairly confident it had something to do with that data-connection required to update the mail, and I feel that it's confirmed: 3 days ago, I found a registry edit that turns off the 3G/data connection after being idle so many minutes (I have mine set to 2 mins). I can now auto-poll my boxes, but my battery life has decreased again...not QUITE as bad as before, but I pretty much have to charge it every night, now.
(Additional "normal" usage for me has always included using Bluetooth for a headset and several calls during the day, varying in length...around 30-50 minutes total talk time, if I had to guess.)
Frankly, I'm surprised at the people who say they're able to leave their data connection on all day (even if it's sending no data in certain moments) and see no appreciable battery-drain. This is my second 8525 and second battery, and my experience has remained the same.
I was going to try and find some sort of push EMail solution...but to make matters worse, I've been doing research and unless I'm misunderstanding things, it looks like WM6's version of "Push EMail" requires that "constantly-on" data connection. I'm frustrated, and I'm seriously considering getting a Blackberry.
If someone can come up with some alternative ideas, I'd love to hear them, but...even though I love my 8525...my patience is starting to wear thin with it.

If you want to leave your connection on all the time and have a battery for the day and night....Blackberry. My tytn is fun to play with and flash but for my email it's blackberry.

Good grief. Is this the consensus of everyone? I'd hate to give up my 8525, since it has Windows Mobile versions of what I work with, plus some pretty nifty games and apps...but I want a device I can both work AND play with. So far, the 8525 is falling down on the Work/EMail end.
I've dodged the blackberry for so long because of 1) no touchscreen, 2) it lacks the versatility of a true PC (ideally, PCs can be used for work and play; blackberries seem meant primarily for work). Plus, I don't know if the Blackberry's "push" EMail features will work any better with my particular mailboxes (i.e., it may have to constantly "poll" those boxes as well, which may result in similar battery drain).
BTW: It's noon here, after 3-4 calls this morning (around 25 minutes or so), EMailboxes updating (2 at 30 mins, 2 at 60 mins), Bluetooth off, and having read 2 CNN articles (and closing it right after)...my 8525 is at 70% power. X-(

[Q] VaniljEclair RLS11 overclocking

Hi all i am microsoft free on my tilt and loving it. i am using VaniljEclair RLS11.
The question i am asking what is the safest speed for me to set in the file for better performance. nbh

Kaiser OC..
Using Rogue Tools, I can run 500MHz without problems. Does use a bit more battery and turns the device into a hand warmer but seems pretty stable. Some run upwards of 520MHz and some do not oc at all. Running Linpack to check performance gains left me wondering if it is worth overclocking at all....
Hope this helps...

thanks the tools work fine.
have anybody noticed that using android on nand for system and data with no oc the battery is worse than windows mobile

Yep...
Battery life will be shortened using most any android device...I disable data, wifi and bluetooth when not needed and I'll go a day and a half at best. If you search the forums here you'll see that most every Kaiser Android user just charges every night....
Also...If you choose to leave data enabled, you can prolong your battery life by selecting to use 2G rather than 3G.....it does help battery life a bit....

Actually, not only kaiser android users, pretty near every android user, my G needs charged every night also, just glad I trained myself on kaiser first before getting my G1
As I have mentioned before, ( many many times, lol), battery calibration is also helped a lot by charging overnight also.

I got a Huawei U8100 a few days ago (to cheap to resist as it was only €100) and battery life seems pretty much as bad as with my Kaiser. Forcing 2G and leaving mobiled data off when not needed is pretty much what you need to do with just about every Android phone to improve the situation.

[Q] Lowering background processes allowed

I sometimes lower background process allowed to 4 to increase free Ram. I did some research and can't really determine if Ram used=Battery used or just Ram in use. On some Roms it seems to make a difference. On DG M7 Rom is was using average 6% or less overnight unplugged but lately on Synergy, Darth, Galaxymod or really any I can't get the same. Usually 10%. On some Roms it seems to help, on others nothing. Any insight on whether this is helpful or harmful is appreciated. BTW I think I may be a battery dork. When the 5hit hits the fan I want a great battery life ready! One more question. I hate the Email app. I only use Gmail. Can I freeze it?

1. Freeze email/gmail whatever you want to freeze.
2. Turn off data when you sleep, and turn it on when you wake up.. will increase your standy duration a lot.
3. Switch to EDGE if you don't care about data speeds.
4. Turn off animations.
RAM used by preloaded apps = 0 battery.
RAM used by active applications/background services = battery used

you shouldn't need to keep clearing the ram and worrying about how much is free. do you know how ram works in our phones? here is an article about it if you don't know.
sent from my i747 with xda-premium

That is an excellent article. Thank you for you responses. I did not understand it to that degree before. It seems 4 might be a little low. Thanks Diablo. I use Juicedefender and I live in the mother of all ATT dead zones so my data is usually off. FIY, when you work hard to get a long life battery and the stuff does hit the fan cause of a hurricane, don't forget to put it in airplane mode until data system is back up. Looks like i need to do more in depth tweaking experiments. Ever since my days with the unbelievably bad Backflip, I have been paranoid.

You could also read the "Android Memory Management" in my signature I wrote it in the days "long long ago" to help people understand how Android memory management works.

Battery problems?

I know, our device has really great battery life and I don't have anything to complain about that, but a friend of mine just got himself a new phone and his values make me a bit jealous and most of all: surprised and stunned.
He got himself a Xiaomi Redmi Note 4 (SD 625 variant, MKT variant really sucks), it has the same processor, same display and not even 700 mAh more (4100 mAh) and he got with some "dev rom" (made by Xiaomi, seems to just be the beta of that ugly MIUI 9, based on Andorid 7.0) 6h of SOT, doze seems to haven't really kicked in in that time. in their forum in the SOT thread I see people getting normally about 8-10 with up to over 12 h of SOT, most of them on stock ROM without any additions. And I'm quite irritated about that huge of a difference with not that much more battery. And he seems quite convinced that it's not on the cost of performance, you should notice that quickly on such a heavily skinned ROM.
Now my question is: how in hell is that even possible? I mean our devices seem quite comparablewith just a slight bump in battery but near-stock AOSP Android against pretty much an iOS clone. Does anyone have any idea what could cause that big of a difference? And if it's software based could that be done on our device? Because my experience and from different posts our device lasts about 5-6 h normally.
I mean I'm already lucky about my 2 days of usage with up to about 2.5 days on some weekends where I have a lot of stuff to do. But I wouldn't mind a bit of extra. But my biggest problem with that is as simple as: how? I could really use some explaination right now...

I don't have issues with device.. stock 7.1.1 with dec.patch, unlocked bootloader, with latest magisk. Also installed greenify.

Then you are one of very rare cases. My experience is about half of that.
And I also meant on stock ROM, without any modifications. So I don't know which apps you greenified, but that was not the point. I use Greenify too but more for apps that aren't supposed to run constantly in background when I only use it very seldomly.

The norm for this phone is 8+ hours SOT. Sometimes I get 10 and a few have had up to 12. Unless you're gaming 8 should be easy. 5 hours means something is wrong with your phone hardware, you have a rogue battery eating app or you're gaming. I rarely charge my phone over the weekend even when I use it a lot.

Well, neither of that is the case and I rarely see people claiming more than 6h of SOT

So the answer to your question is, it's the wrong question. The question should be, why does my battery not last very long and what apps or usage causes me to have such poor battery life? Compared to the Redmi Note 4 the Z Play is exactly where it should be.
Here's a link to the SOT thread: https://forum.xda-developers.com/moto-z-play/review/screen-time-t3643959

Here's an app to help diagnose battery condition (Accubattery): https://play.google.com/store/apps/details?id=com.digibites.accubattery&hl=en
also betterbatterystats is really helpful.
I sincerely hope you get it sorted out!

Well, gsam isn't detecting any app that's off even with root so I don't think there is any. I installed that AccuBattery app, let's see what it has to say

Removed because of ****ty q&a system...

Oh, and another thing I noticed: I get very randomly reboots, and every time the battery percentage drops massively. Just had a 30% drop. And after the reboot the battery percentage seems like frozen. Now I rebooted and plugged in the cable and got 44% again... No fast charging. Do that detection seems very off
Motorola forum isn't helpful at all. Clearing cache and dalvik didn't change anything and running around for a week in secure mode (that's how random they mostly are) or even doing a factory reset without restoring apps is out of question for obvious reasons.

That's pretty weird. Did you try a factory reset and after restore your apps? There's not a lot you can do if you're not rooted, but you shouldn't need to do much anyway on stock rom.
Only other option is full RSD lite OS restore as a last resort.

I am rooted for long, that's why I use Greenify. I know it also works without but then it's a joke. As RSD lite is, it just refuses for everyone to detect anything on Windows 10.
Factory reset is out of question for the moment, it takes way too long to do it properly (with titanium and NANDroid backup first) and I won't have that much time probably for the whole of this month. Otherwise I would most likely already have went off to the next best custom ROM since Motorola just can't get their **** together and still work on 8.0 in test for 2.5 month with searching testers for another one.
I think the next thing I'll do is to try the good old battery calibration, just have to find the file storing the statistics. I know many say that won't work but that's rubbish, it worked for me already a few times

Update: no, no change. Don't know if that funky battery percentage bug on random reboots still happen since I haven't had any again yet, but they come too random and unpredictable.
And that AccuBattery just proves to be worthless. It tries to estimate the rest capacity, but then it even fails to detect original capacity by 500 mAh. The battery sucker stats are also unrealistic. It puts chrome first with 10%, while GSam with root puts it 5th at 4.6% after kernel, Spotify, Android system and fight services. Android itself even puts it 9th with screen, phone idle, cell standby, Android OS and Bluetooth in-between.
So let's see what happens first. Motorola releasing 8.0, which I will flash through the .xml.zip, this time using flashfile.xml which should force a factory reset... Or me finding the time to switch to a custom ROM
Edit: so I got another one, bit this time no crazy battery drop. But the other times I killed of the soft reboot sequence because Magisk can have some problems with that. This time I didn't

Yesterday I was finally able to do the factory reset since those darn random reboots became too annoying and Moto's support is had just the most ridiculous ideas... In the worst way.
Either way, now OTA looks better, let's see how it will turn out in the next days
