Seems to be an inordinate amount of dissatisfaction with "this ROM" or "that Radio" due to perceived sudden battery drain.
I believe that I have far more variance in battery drain, day to day with the same setup, than I have due to changing ROM or Radio.
I have sometimes run the exact same setup for several days in a row, yet one day it will seem like battery is lasting forever, and another day it seems that battery is draining very rapidly.
IMHO, of all the criteria of importance in evaluating a new ROM or Radio, battery drain is towards the bottom of the list. Just like my laptop, I make sure that I always am prepared to renew my charge - I have a charger at the office, at home, and in the car - at all times! My Wizard is my everyday tool, and function and stability are way more important than battery life. I plug in and gas up whenever I get the chance, so I have never had an issue with running out of juice!
My opinion is that charge and drain cycles, and program use, probably account for 90% of the perceived variance.
Am I the only one that thinks that battery drain issues are over-hyped?

Your probably not the only one who thinks the issue is over-hyped ,that said it is very much an important issue. I'm not sure that I would list it at the top of my must haves list but isn't anywhere near the bottom. A stable working rom is what matters most but what use is it if requires you keep a spare battery in pocket to use it. These variances are certainly not figments of our imagination as I have seen my wizard go from lasting 3 days to less than one with no change in the useage profile.
I've never had an issue with battery drain. But -- like you -- I keep my Wizard "topped off" with a charger at my desk at work, in the car and a desktop cradle/charger at home. When my battery life drops below 80% it goes on the charger wherever I am.
I also find that my battery life is in direct relation to running apps/Today plugins more than ROM issues. So, if I don't run some of the more power-intensive apps, my battery lasts longer.
That's my story and I'm sticking to it. . .
Typically there is one or more programs that cause the battery to drop quickly. I know that recently after I performed a hard reset on my x-bow install (Orwell's), my battery drain problems went away. However, when I restored the backup, they came back so I went ahead and performed another hard reset, and installed all my programs one by one again. After a couple of times doing this, the problem finally went away. Believe me, it got so aggravating at one point that I switched back to AKU 3.2. I did install the 02.61.11 radio rom, and I think that may have helped.
The issue is not overhyped. I know that it happens, but a lot can be resolved by being patient with what we install and when we do it.

Hi Actually, yesterday I took my phone from the charger at 100% at 7AM, by 6PM I had less than 50%. Only used it twice for a regular call and a couple of texst messages. Today it is a lot better. It alternates between fast drain on one day and then another day it could be good. I am using Faria's V2 rom, 8mb pool. As far as the memory leak in Faria's V1, a beta version of today agenda came out that I am using on Faria's V2 and have not had memory leak issues. All in all, it's a great rom, even if it has the battery issues, Cingular did a crappy job with the original rom.
ROM upgrades
ROM upgrades reset the battery history, so that it has to learn how long it lasts. This makes for a lot of variance in battery percentage, but not in voltage; all it is doing is learning how voltage translates into battery duration. Usually just a day or two after a new ROM and battery drop stabilizes. But it never learns perfectly -- my battery stays at 100% for hours and then starts falling a percent or two an hour.
Wifi uses up a lot of power. Just being connected to a bluetooth headset doesn't seem to use much but if it is searching for the headset (e.g. because it is off) then it uses a lot of power, although not as much as wifi. Searching for GSM also uses a lot of power and if I know I will be out of touch for a long period of time I turn off the phone, but just being connected to GSM doesn't seem to use much.
on a thread i read to use the device unlocked option, it worked for me
Exactly, the biggest factors for battery usage are (apart from wifi and using applications of course):
1) reception quality
2) data connection
example 1: London, crap reception at home, average usage, two mailboxes checking mail every 5mins, gprs always on : 7am - 100%, 8pm - 25%
example 2: Same as above but one email checked every 15min, second every 30min : 7am - 100%, 8pm - 50%
example 3: Egypt, reception always excellent, no data connection, usage SLIGHTLY less: 7am - 100%, 8pm - 94%!!!
Anyway, that's the price for the performance I guess, if the battery life would be the most important thing, I would buy Nokia 6310...
Here's an amazing discovery. My phone was at 25% in about 8 hours. I will leave the phone at 100% at night and it will be at 75% the next morning. By chance I purchased a brand new battery to place in another phone that had a broken usb. I placed the brand new battery in my old phone to charge it and at 100% I removed it and placed my old battery and charged it to 100%. Now I leave my phone at 100% at night and the next morning its at 100%. Go figure...... Overnight, the phone radio is on and so is bluetooth
Suspicion, drain rate is a memory issue....... comments

I totaly agree, I have my PDA hooked to Exchange with wireless active sync and full attachment download. If I was to say get 5 emails with 10 MB attachments, and then have a 2 hour conversation with some one I haven't talked to in a while I would most definately use more of my charge that day.
The point is that to me battery drain is more about usage either perceived or not. I set my PDA to do whatever it wants, so that is what it does.
One thing that i have noticed is how you charge your Phone. I have noticed that if i charge my phone with the home wall charger i'll have to charge later that night. But if i charge it thru the USB cord from my computer, the phone stays charged for almost 2 days. Thats why i only charge my phone now thru the usb cable. if you dont believe try it out and you will be amazed.

that's quite strange - definitely not the case for me...
well everyone i work with here has a pocket pc and i told them to try that out and they actually noticed a difference in how long the battery would stay charged even with regular usage of the device. So either this must work or im a real good manipulator.
Hi all...
I face this problem. Battery life is really dissappointing!!! I don't know why but i use only bluetooth hands-free. No GPS, no Wifi, no camera, i have also disabled 3G and HSDPA and my Kaiser's battery lasts not even a day!!! .
I also have installed battery status to check temperature and CPU load and when Kaiser "sleeps" CPU load is approximately 1~5%. This means that nothing runs in the background!
I have not installed on my kaiser anything more that i had installed in Artemis and Artemis battery keeps 3 to 4 days!
Is it a battery problem???
Same here. Just received Saturday, but I already had to charge it twice.
I just stopped using S2U2 (Slide 2 Unlock 2), maybe this will be a battery eater?
My HTC Kaiser can survive more than 2 days with occasional 3G/Wi-Fi usage (about 1 - 2 hours/day) , SMSes, several short phone calls.
Same experience than Gogol, 1 day with intensive 3G (HSDPA disabled) usage (Push mail, etc.), or more that 2 days without 3G nor Wifi.
For me the battery is enough good, not as good as i want, but enough.

Yep..same here..battery usually lasts 2 days. My usage is Wifi 20 mins/day, calls 30 mins/day, other usage 20 mins/day.
Same problem with both HTC Kaiser and MDA Vario III - Radio ROM to blame?
I had a HTC Kaiser, which I sold, and now have a MDA Vario III. Both have the same short battery life (barely one day with very little use).
Battery droped from 38% to 32% in five minutes while I was on the phone with T-Mobile support.
Batteries seemed to be different though. My Vario III has a black battery - DynaPack, KAIS 160, 1350 mAh. HTC Kaiser had a white battery, and I believe was of different brand.
It reminds me of a similar battery problem with Trinity with one of the radio ROMs, excellent reception but very poor battery, same as Kaiser now.
I am getting a new battery from T-Mobile on Thursday - will let you know if it helps, but it does not look promissing so far. If it does not help, the device goes back to T-Mobile for sure.
Strange,
But you need to check what are currently running in the background.
Check using "Settings->System->Memory"
That could eat your battery a lot Especially ActiveSync !
S2U2? I am only aware of Slide2Unlock, not a version 2. I have the original one installed. I think I got rev 1.20, not the latest 1.21. But there have been some reports of draining with S2U. I don't have the issue, I don't think. But in his latest 1.21 rev he says he may have made some changes to address power draining issues. Tho the dev says he doesn't have the issue so he can't be sure.

I face exactly the same problem! In 1 hour and the phone untouched... the battery went from 40% to 30%!!! Please let me know the results of your new battery.
I just did a small test. My battery life sucks, usually having to charge the phone every 4-8 hours.
I took the SIM card out, rebooted the phone and left it set for 10 hours and never touched it (I used my Treo during this time). After 10 hours of just sitting, I lost 9%.
In my opinion, that is NOT a good battery!
all HTC Kaiser model 160 come with the black battery
Taking a poll
My experience with a PDA phone, is with what I call "normal" use, one day is all the battery should last. I'm on my fourth HTC phone and the first three this was always the case. With the Tilt, it can loose 10% doing nothing. It's like watching the gas gauge on a 72 Chevelle SS with a LS6 engine. I dare say the battery will discharge 10 times faster than the previous phones. Since some are not having this experience I wonder if we can take a poll and find a common denominator. If anybody can think of some more variables please post them.
1. Which model do you have, Tilt, Kaiser, ect?
2. Which ROM are you using?
3. Did you fully charge your battery when you first got it.
4. Which SD card are you using?
5. Do you leave wifi or BT on?
6 What brand battery do you have & mAh?
I used 3g connection and wifi for atleast 2-3 hours a day and make about 5-10 short calls. I also watched about 30 minutes of streaming video. I haven't charged my phone for 22 hours and I am at 37% which doesn't seem that bad to me. As long as it last all day I am fine with it. I just plug it in when I go to bed.
Here are one site with lot of ussefull info about batterys, and how to make them work for more time...
http://www.batteryuniversity.com/
I have noticed that the battery goes down quickly if i have bad 3G reception, and the PDA is changing beetwen GPRS and 3G every time...in this case is better to disable 3G.
I have BT on all the time and use GPS with TomTom 30-60 min a day. And every time a can, i charge the battery (shorts charges). If you read the URL above, the recommendation for LiIon batterys are shorts charges many times instead of long charges and complete discharges.
Regards.
I will have had my TyTN II for a week come tomorrow (Saturday). I have not been using HSPDA or 3G, but have kept up my normal usage of phone, text, WiFi, and playing around with the device every day to learn it.
So far I have only have to charge my phone once; will likely have to tomorrow.
While Lithium batteries are not supposed to have a memory, I have always used the practice of charging my batteries overnight the first 2-3 times and completely draining them before the next charge. To date it has served me well when it come to battery life on my devices.
Also note, most phones "quick-charge" to about 80-90% very quickly then trickle charge the last 10-20% for the last hour or so of charging. Not sure if this device dows the same.
Hello, I've recieved my AT&T Tilt 8925 (Kais100) unit a week ago and ever since I've experienced awful battery performance. The item shipped new (not refurbished supposedly nor defective) and included a Samsung battery. I changed to Dutty's v3 ROM right away (flashing was successful, I also switched to radio version 1.27.12.27) and last night switched to Q-Mobile v1.2 to see if the ROM was the problem, but it persisted.
My battery drains extremely fast, even when the unit is off it drops 10% after 8 hours (overnight and also throughout the day, I'm leaving the unit at home while I solve this issue and it's always off). The unit does not have a SIM card inserted and the Phone function remains off, so does WiFi, Bluetooth, Beam, 3G, etc. It's also muted and has no alarms activated, nor background programs running (I'm currently running a freshly flashed Q-Mobile v1.2 ROM with a hard reset done as well).
I've read about battery perfomance extensively but haven't ever read about the battery discharging while the unit is off, and given the fact that I'm NOT using the phone functions, I barely believe this can be normal behaviour. I purchased 2 units from the same source and both are having similar issues with battery perfomance.
I'm currently testing a borrowed OEM Dynapack battery from a friend's Tilt to see if it shows the same behaviour as well to discard the possibility of a faulty unit. Note that I'm using the OEM 1A charger and leave the unit charging for several hours.
If the battery proves to be defective I'd have to get one (or contact the seller to see if he'd respond to the issue). Can someone recommend a cheap/reliable battery that could be bought online (eBay, etc.)?
Thank you very much! I hope that someone has a clue on this issue.
Best regards
Sebastian
Just to clarify, is the phone actually OFF, or is it in standby? If it's in standby, 10% after 8 hours wouldn't be unreasonable at all.
Uhm, it's on standby I guess (when I turn it on again it's instantaneous, not like when you soft reset the unit)...
I'm new to PDA phones, I had an IPAQ RX3715 before with WM2003SE and I could leave the unit off for days without battery drainage. However I may not be too familiarised with these new units' standby/off functioning. If in standby and with the Phone function off (meaning that the device has "nothing to do" other than being off) it's normal for the device to drain the battery so much I would be disappointed.
As a sidenote, my friend's Tilt is not draining while it's on standby being on the same conditions other than the fact that his unit has the Dynapack battery.
Regards!
Bat Drain
I have the same rom and the same problem. I was at the hospital all day i made two calls and about mid day my bat was at 30%. I think its duttys rom V3 causing the problems. Changing roms now.
I could be wrong, but I think your phone is fine, these devices just consume a lot of power. 10% over 8 hours would be totally normal in my opinion. Is that the main reason that leads you to think there is a problem with your phone? Have you ever had a pocket PC before that had better battery life? When I got my first PDA I thought the same thing, but I realized that they are not like normal cell phones, where you could just recharge once every couple of days. PDA's must be charged at least every night. If you use GPS or wi-fi a lot you're probably going to be charging sometime throughout the day as well. I just got into the habit of plugging it in every time I get into the car, and when I get home I plug it into either the computer or the wall charger. There are after market batteries available, but if you want a drastic increase in amp-hours, the battery is going to be bigger and it will require a new battery cover. This is totally unacceptable in my opinion, as the device is relatively large to begin with. My advice would be to only activate a radio if you are using it, and de-activate it when you are done. Also just get into a routine where you are charging it whenever possible. Another thing, I just flashed Dutty's V4 RTM, and I must say the increase in battery life was very noticeable. Don't let me confuse you, though. From the information you supplied, I really am not able to tell if there is a problem or not, so give some more information and examples of battery life so we can figure out if somethings wrong, or if you just aren't used to the amount of consumption of this type of device. Hope I could help. Cheers!

Yeah that's not normal. You got any radios besides phone running throughout the day?
Thanks for your thorough reply. Picking on what you mentioned, it's true that I'm new to PDA Phones, as I mentioned I also own an iPAQ rx3715 with WM2003SE and my idea was to replace it. Judging the fact that PDA-only devices, to my eyes, are nowadays dying I thought I'd get me the latest and most complete device available WITH GPS, since I was using my iPAQ together with a GPS Bluetooth Receiver with much delight.
What I experienced with my previous device was that battery performance was never an issue, it did consume power as any PDA, but I didn't find myself worrying about it, it never dropped when off and it would last me several days.
Since I'm using my Tilt with the Phone function off I _thought_ it wouldn't need any power for anything... but it might be that these new devices, or the new WM6 architecture is different to that of WM2003SE/PDA only devices... I don't know, but it just sounds strange to me, although if it's normal I'll live with it- as you say, I'll have to be charging it 1-2 times a day.
On the one hand it would be good for me to know that my device is ok, but on the other hand it means that battery life isn't even close to what I expected... I had read people complaining about it but in general I tend not to be overly critic about the defects of devices... but it seems that it's the case. I meant not to use the phone features and thus I thought it wouldn't be consuming power on standby seeing that the phone should not be running anything on background...
Thank you again for your reply. If anybody else has a word on this I'd appreciate it.
Best regards
Just as an aside you will notice the battery life getting better after a couple weeks it seems the battery has to be conditioned so to speak. Also do you have any kind of push email on your phone as if you do that does use quite a bit of power, you might want to set it up as a pop3 account and set it to check emails every so often instead of getting them as soon as they come in.But I have amde it a habit to always use my charger whenever I am able to as these batteries seem to be happiest when topped off whenever possible.
Hello again, I'm still experiencing this problem and it seems not normal.
Simply put, I fully charge the device. I turn it off. It discharges by itself with all wireless functions off.
Today I did a hard suspend (keeping off pressed) with battery at 60%... when I turn the unit on 7 hours later the battery was at 6% with a critical warning sign.
I'm NOT using the device, I turn it on, use WiFI for 3-5 minutes then switch it off and put the device to suspend. I turn it on after a couple of hours, play with the menus and turn it off again. Just by doing that the battery drains by 10% every 5 hours or so, sometimes it won't even turn on due to battery drainage.
Is this NORMAL? I need to know if my unit or my battery is defective so I can return it to the seller in time...
Thanks, best regards
Sebastian
Battery life DOES seem to improve with time. The first day my battery wouldn't last for 5 hours! Keep charging your battery and letting it drain as much as you can (whether or not to let it fully drain is debatable), and I bet you'll see some guaranteed performance.
Also, what would help a lot is if you found and installed the Today plugin BatteryStatus and checked the "Show More indicators" option, and see what your battery drain was. The normal is between 150mA and 300mA when you're on the Today screen. Any more than that, and you most likely have a problem, assuming connections besides phone are off.
sounds normal to me, turning off you mean by pressing the button on the right side of unit? if so, mine is the same way
I'd say that was definitely not normal performance. On average, I use mine for at least an hour worth of talk time, an hour or two running TomTom, numerous SMSs, and at least a couple of hours reading books. I charge it every night, and the battery is generally running at around 50 to 60% by that time. I'm surprised at how quickly yours is draining.
I have an RX3715 inhabiting a drawer, and, while the battery life was a lot longer on that device, the battery was a lot larger, and the screen lower quality. The fact that it is not connected to a mobile network gives the battery a much longer life too. When I used it purely for TomTom, connecting to a bluetooth receiver, the battery faded very fast.
I've had a Kaiser since day one. I have found that adding a comm manager that allows forcing the phone to Edge give huge battery savings. In standby with the phone radio On and BT radio ON, WiFi OFF, my phone drops 4% over night very consistant. On Edge battery lasts days.
The only time I get fairly high battery consumption is streaming with 3G. Edge is so much more efficient on the battery, so if you don't need the speed, throttle down!
The only time I've ever found the phone Dead or close to dead after only a few hours on standby was when I had WiFi ON and the phone in standby. I can't pinpoint what exactly causes the condition, but when it occurs, the phone is HOT and the battery heavily drained in a short time. This has happened with both Hermes and Kaiser. I never leave WiFi ON when not needed, and have never seen severe battery drain since.
I do sometimes turn off all radios except WiFi, and then use wired ear buds and stream Slingbox video to the phone over my home WiFi LAN. I can get almost 4 hours of watching on a charge.
The battery should not be draining when powered off, but not much at all when put in sleep mode. Get yourself a replacement Testing.
As an aside, Alex's WM 6.1 BETA 2 has given me the best battery life of any rom. Only about 25% of the battery drains per day. With most other roms it's 50-100% per day.
Hello, thanks to everyone for your replies. It's strange because I've been doing lots of test, switching batteries (I have 4 units to test now) and I get inconsistent results... the 2 most problematic units were bought from the same eBay seller and got their ROMs changed the first day, the 3rd unit still has the AT&T ROM and was apparently not draining as fast. The problem is that the 2 first units seem to get battery drains overnight in flight mode of 10% and 2 times one of them got a 0% critical battery status just by being in standby and not in use (none of them are working as phones and have the function off)
The odd part is that for some reason this happens only sometimes, now I've switched to Sleuth's WM6.1 ROM and the problem is gone for now, I'm still at 90% since 2 nights ago having turned on GPS and WIFI for 5 minutes each 2-3 times... the other 2 units have been in standby from 100% charge and they haven't dropped either! And they're using the AT&T ROM and Q-Mobile v1.2 respectively... what kills me is that I cannot say what's wrong, cause I've swapped batteries, swapped chargers, swapped ROMs but cannot trace which is the problem (or if there's a problem at all)...
Perhaps it's normal for the unit to sometimes drain 10% after 8 hours of standby in flight mode and on other times remain at 90% for 2-3 days if not in use...
Thanks everyone for the read, I'd appreciate any comments
Regards
Sebastian
What radios are u using. Try changing radios
10% loss overnight in standby would be normal.
Does the unit get warm when you notice rapid drain?
I wonder about the "old" active sync problem - does the device show any running programs when you turn on?
In general you should expect to get a days worth of power using it for the odd call, perhaps an hour of wifi and perhaps an hour of prgram use. Of course all taht is very variable but I generally get away with a charge once a day. Occasionally, I take it from it's holder and it's warm to touch, but usually it's 'cos I've forgotten and left something like tomtom running.

I was not able to find anything like this yet so figured Id post. Lately my battery is misbehaving. I can fully charge it to 100% make 20 min phone call and viola Im at 40% moments later it seems im at 4% WTF could be the culprit I wonder. I was running Garmins roms and now Laurentus and the same and I remember laurentus's being exceptional on battery. Could my battery have become defective? Regardless **** HTC I WILL NOT BE BUYING ANOTHER FOR THEIR TREACHERY
I have had the same problem with some WM6.1 ROMS.
If fact today, I flashed back to 6.0.
Never had a similar problem with 6.0.
check out my general forum post http://forum.xda-developers.com/showthread.php?t=410590
it seems that 6.1 drains batteries bad. i have come to found if you use kaisertweak and enable power management, it helps quite a bit. also, there is a hyperlink in my post that has another link that one guy claims his SIM card was causing a bad drain.
your drain issue though is a bit EXTREME. take your battery out and lay it down on a flat surface like your desk and run your fingers over it and look at it. if the battery isnt flat or relatively flat, your cells may be swollen from too much charging/draining and it could be time to replace it. ATT warranty replacement wil do it for u in the first year
I am using dutty's rom 6.1 and I dont have battery problem at all. have u checked apps running in back all the time? that s might be it.
Battery might be simply used/defective.
Battery is OK. Have spares.
Also check them and read through link posted by richabi.
Agree, it could be something running in background, but
use a Task Manager to shut down programs.
Could be a simple problem I am overlooking.
However, this morning, the Kaiser I flashed back to 6.0 last
night was fine.
Still have 6.1 on Tilt so I can compare them.
What Radio are you using? And which ROM?
Certain Radios are notorious for draining the battery quickly.
I am running the NIKI Radio 1.65.24.36 and that eliminated my excessive battery drain. I am also on L26 V9.

It is in my signature, HyperDragon IIIs Radio 1.58.25.17
Now using Radio 1.71.09.01
Overnight battery drain is same as 1.27.12.17.
4%
See signature.
Will see how it goes during the day.
1.65.24.36 on Garmin v1.2 battery drain is about 2% each hour. and about 4-5% per hour when browsing internet or doing other activities.
Original att 6.0 rom with 1.2x radio battery drain is about 5% each hour, and about 15% each hour with internet browsing...
I couldn't figure out why there is such difference but it's good to compare.
My screen brightness is set to lowest setting (never really use it in the sun or outdoor when surfing the net)
Hi all,
I've a tytn II PDA phone with Hyper Dragon III rom
From 3 day I've problem with battery, draining very fast from 100% to 60 % in 10-15 minute. no application running in backgrund.
I've resetted terminal (hard) but the problem not solved.
I've restored the PDA with the original radio and rom but nothing!
I've purchased a new battery but the same! The battery draining fast!
Today for expample from 90% to 80% in 3 minutes but if I restart the phone
the battery return to 89%!
Anyone have a solution for this problem! Exist a software to permit the battery calibration?
Many Thanks
Battery calibration is simply done by running it down completely until the phone shuts off by itself. Then remove the battery, wait 10 seconds, insert again, repeat. If the phone shuts off again in less than a few minutes you're done, plug the charger and recharge the battery fully until the green light is on.
It may have to do with the radio version you have on the device.
I recently tried that ROM on my device along with several others and ended up having radio 1.70.19.09 and battery life was horrible, just HORRIBLE! I flashed just the radio to the version that was on the device from new. Give radio 1.65.21.18 a try. I now have awesome battery life.
