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.
Hey guys.
I'm using an Artemis and i'm very satisfied with it. But from time to time i'm thinking about the Kaiser...
But the Kaiser's got the faster processor. My battery in Artemis is running very long, what about batterylife in the kaiser ? How long does your battery run ?
Thanks in advance and best Regards
Peter
Battey life:
TBH I have been truly amazed - normally with the XDA-Exec (universal), which I admit i used to push very hard, it would have to be charged daily. However, I'm finding with Kaiser it just seems to keep on going. A few minutes on ActiveSync and thats its lot for the day and it just hovers between 56% and 86% all day.
My Kaiser's battery is the only problem i have. I get it in the morning with 100% battery and never lasts more than a day!
I have 3G, WiFi and HSPDA all day off and i am not using camera or GPS at all! Only bluetooth for my hands-free.
What is your opinion about that? I am thinking to send my Kaiser at Service.
Waiting for your opinions.:
I had Artemis too with BatteryStatus at 286MHz and boost at 299MHz and battery gave me 3 days!!! I really miss it!!!
Im quite amazed myself. I have a N95 and usually compare my HTC Kaiser with that, and battery wise the Kaiser is far far superior.
I use a lot of WiFi and im always connected to 3G, but still the Kaiser lasts approx 2-3 days before I need to do anything.
I am amazed at the battery life on my tilt! I recently did a 30 day trial of the Mogul and the 1500maH battery on that device was horrible (maybe because of CDMA?). My tilt with moderate usage, e-mail, surfing, GPS, and phone usage lasts all day with no problem. Not sure if it matters but I am in 3G areas about 90% of the time!
Well, when I first got mine I couldn't even get a day out of it so I arranged with T-Mo to send it back under my 7 day cooling off period as I might have a faulty handset/battery. I then could order a new one which hopefully would be ok. but due to all the postal strikes in the UK I am still waiting for the packaging to arrive so I can send it back, but, in the mean time after a few charging cycles, the battery is fine, by the end of the day I have about 20-25% left, but I am using it a lot, few hours HSDPA surfing, 30 mins or so GPSing, loads of txts and emails and 15-20 mins of calls.
I know most people wouldn't think that one day is very good out of a phone, but with my usage I think its ok what I'm getting. when I first got it it would be dead by 7pm!!!
Prior to upgrading to Tilt, I had 8525 for nearly one year. Battery life on 8525 was about ten to twelve hours. On my Tilt, it is approximately the same.
Many threads on different forums about 8525 battery - my battery fell within the median of user's experiences.
Here's my battery life:
I'm plugged in all day at work. Last night, I left work about 6:45. I have 3 email accounts pushing mail as they come in. I have bluetooth turned on. I made one phone call last night (~ 5 minutes). I checked a website for a few minutes. The screen was slept the rest of the evening. This morning, I checked the same website for ~5 minutes. I got to work about 7:30 am. ~35% battery life left.
To me, this is crazy. I had a treo 650 that I wasn't pushing email on, but the same phone use (web use on the Tilt is negligible in my opinion) would last me nearly a week.
Does pushing mail really suck down a 70% of the battery life in ~ 12 hrs?
That's nuts.
Robert
Hey guys,
thanks for all your answers !
Hmmm....i'm not quiet sure to buy one at the moment....
Artemis with 200 mhz has really good batterylife - anyone downclocked the Kaiser processor ?
I think this would be an advantage with battery, don't you think ?
I'm very keen on Kaiser, but with only 1 day battery it's absolutely no solution for me...
Cheers, Peter
Comparing my 8525 (which I "band selected" to Edge only) and 8925 (where so far I can't figure out how to disable 3G), the 8925 has extremely poor battery life.
I was 100% charged at 7am. It's 4pm and I'm down to 15%. Haven't used wifi at all and have had max 5mins of phone calls. I did stream to my BT headset at lunch while I was at the gym (30mins).
But typically, in this regular day, my 8525 would still be at about 40% at 8pm.
Hopefully someone can figure out how to user-select 3G.
Thx,
Joseph
Just load a different Comm Manager from the Kaiser Cab thread, they have a 3G button that you can hold off 3G with.
Generally speaking i have experienced good battery life, but i recently noticed when i was looking at the batterin information in my TBattery 0.56 that it says the full level on my batter is 1380mAh, but on the battery itself it says it's 1600mAh battery. Is that a glitch in the software or is it possible that there is something wrong with my battery? Thanks for anyone who has an idea. I uploaded a screenshot to show what i was looking at.
get yourself a 3000 mah battery and try finding a different radio

Where does that software come from? Sounds cool, but I can't see a hint of it anywhere
It seems some Kaisers have battery life problems and others not, for some random hardware or software reasons. On mine I'm amazed at being able to hold an entire day with VERY heavy usage like wifi, EDGE, GPS, music over bluetooth headset etc. Usually my uptime for a day reaches 6hrs with that kind of use, and the battery will last about 7. It's the longest battery life I've had with all my HTC devices so far (Blueangel, Wizard, Hermes, Kaiser).
Ok so if you dont know the 8925 has probably the worst battery life of any HTC phones I have ever used. It was like they decided to put all the latest and greatest into a shell sexier than hell, then give it a old 8125 battery,
The 8125 had what a 1250mAh battery, so they give the 8925 a 1350mAh, makes no since. I am still use to my P990i having a 1500mAh battery and getting 7-9 hours of play time and a 10-18 day stand by time.
Are their any upgraded batteries out yet? if no I may just have to get a second battery and charger cause I cannot go the last 4 hours of my day without a phone. Oh and a car charger is out of the question. I swear those things were made by battery companies to kill you battery faster than shizzit.
Actually, I have found that after a few full charges and running the battery down to about 5% it lasts pretty good.
The first day I had it I had to charge it after about 4-5 hours. Now I am using it most of the day.
if I'm 3Ging and/or GPSing, it goes fast.
if i'm not doing those but doing anything else, it lasts a long time. Easily a whole day.
3G is a huge strain on battery life. Don't expect to get anywhere near the battery life you did with the 8125 if you are using 3G.
With my 8525 I would get 9 hours of battery life at the most (100%-0). With the Tilt, I have been getting about 12 hours of battery life with about the same amount of use.
I run WL push email all day and browse the web pretty heavily.
Make sure to condition your battery by running it all the way down to 0 before you recharge a few times.
I have been conditioning the hell out of my battery so far, 100% down to %5ish, 100 to 5 100 to 5, only charges it and gone through like 3 cycles so far. Hopefully I will see something soon
anyone know of any batteries out there yet? if no I will put an order in for another OEM HTC

lol. that's a trust worthy site.
Just a note - conditioning a LiIon battery has zero affect on its charge capacity.
I'm getting between 8-10 hours of very active use and 10-16 hours of life when I'm not on the silly thing all the time. SPB Pocket Plus calculates my battery life at around 10-11 hours, and it's usually pretty good at estimating it once it's seen enough data.
Nevertheless, I can also attest to the fact that the battery life of my Kaiser is increasing. I'd say its about 25-30% better than when I first started using it a few weeks ago.

Where do you see this feature in Pocket Plus?
I am hoping Slueth is right about the battery life increasing over time. Mine isn't a 4th of what the 8125 or 8525 was. The comments on 3G being a huge drain I can't agree with. The 8525 and 8125 had the same battery consumption and I could get a full day of regular usage on both.
I can say using the Kaiser rom over the at&t rom made a noticeable improvement.
I live in HSDPA nation [Bay Area]. My tilt gets pushed to limits everyday. I have mobile shell installed with weather update, push email and active sync through exchange server, use ICS with laptop on the go. I can get through the day with heavy use and the battery never falls below 40%. At 11:00PM last night, I had 75% left on my battery level indicator.
I would say it's about 20-30% better than Hermes' battery performance.

That's AMAZING! I wish I could have spent 75% by then and still have 25% left. I use everything you mentioned too but I barely make it t 7 or 8 pm before my tilt turns off at 1% battery level so I have to stick it in the charger as soon as I get home from work at about 6'ish.

Add the battery meter to one of your tabs and look at the options for the meter by tap & hold - options. It allows you to set a fixed battery life or use a statistically estimated duration.
The comments on 3G being a huge drain I can't agree with. The 8525 and 8125 had the same battery consumption and I could get a full day of regular usage on both.

It all depends on your actual data usage. If you aren't transmitting a lot of data, then the HDSPA usage won't have a significant effect because it isn't on all that frequently. If you do, you'll definitely notice a difference.
Mine was showing about 75% this morning and is now at 57% (5:30pm) - that is following three or four short phone calls, several web page downloads, several synchronisations via bluetooth and ten or fifteen minutes experimenting with the business card scanner.
I do agree with other comments here that battery life improves after several charge/discharge cycles. This Kaiser replaces my old Hermes - I think the battery life may not be quite as good, but it isn't vastly worse - trouble is that it has so many fun things to play with that you just do more with it! Just the GPS alone will draw that battery down if you use it too much - my hand-held Garmin can flatten a pair of high capacity AAs in less than 24 hours - and that is not powering a 3g transceiver and bluetooth at the same time.

i must say, i have the case of not able to leave my phone in my pocket. I always have to have my phone out, turn on from sleep and do something with it. If I'm able to resist this temptation, my phone can last the whole day going down to 50%. If I'm messing around with it, then it could go below.
I noticed that Skype is a MAJOR draw on the battery.
When I had skype on and logged in, the USB charger could barely hold the charge even ... when I was also using GPS with Google maps the battery life was visibly going down.
After using the device more normally now I get quite decent battery life.
The real test will come when I fly cross country and read an ebook on it.
If i can resist the urge to play with the GPS i can get about 2 days out of mine, but my useage is pretty light. I am using Direct Push with my exchange server, and get about 15 emails a day. The TCP timeout on my firewall is set to 1 hour, so i think that helps too. I am using the black & blue comm manager with 3g option, and i leave 3g off(it switches between 3g and Edge all day at work, and i heard that can lower battery significantly). I only enable 3g if i tether, and even then 3g coverage in my area SUCKS! Verizon has EVDO everywhere here, at&t needs to get their ass in gear . Overall i'm happy with the battery life. I've setup a few PDA's for some of my users here so i wasn't expecting anything great (although our two blackjack users seem very happy with battery life).
Just placed an order for the 1600 mAh Tilt battery
Hi,
I was confused by the different batteries available for the Tilt at www.batteryupgrade.com , so at I e-mailed them this message,
Just found your site, and am interested in purchasing a battery for my ATT Tilt/HTC Kaiser however; when I looked at my battery it does say KAIS 160, but the P/N is 35H00086-00M, and not 35H00088-00M. The device is ATT Branded, and in the device info on the phone, model number just says Kaiser, not Kaiser120 etc. Is there any difference, what battery should I get?
they gave me this link-
http://www.batteryupgrade.com/product_detail.php?productId=75070772&searchphrase=htc%2520kaiser
Just waiting to see if it does help alot, if not, I'll at least have two batteries now! lol
Alemaker
Terrible so far... but i've only been through one charge cycle, almost. I topped off the out of the box battery. From there it's been plugged into the computer while i was adding w***z (i mean perfectly legal software). So I've never actually winded it down to 0.
Is it bad to keep topping it off like this?
The battery life i've been having probably wouldn't even last a day but i should probably go down to 5% before i charge it again and see if it improves.
My motto with this phone is "Who needs decent battery life if you've got GPS, a 3MP camera, an unbelievable library of third pary software, 3G, a fully qwerty keyboard, gorgeous touch screen, and tilting screen?"
i know what you're thinking this issue has been repeated so many times, but i am at the end of my rope here. There is no way i would want to trade my Tilt for any other phone, if someone could help me with battery life I would greatly appreciate it. I searched for battery drain, battery, battery life, battery life tips and maybe i missed something but none of that really helped me.
Here's what I'm doing:
Bluetooth is never on (except for a quick file transfer then off again)
Wi-Fi is rarely on, unless i know i'm going to find a hotspot and then i'll use it for maybe 5 or 10 minutes.
There is a mixture of 3G and EDGE in my area
My backlight is a little less than half brightness.
I've followed all the tips in chapter 13.7 of the kaiser manual (i'm running the kaiser rom with updated radio (.17))
I've used kaisertweak and made some changes that are supposed to increase battery life.
I have no idea what to do anymore. Just now with my phone in flight mode i took about 5 3MP pictures and the battery life went down by 4%. Is there something that I'm missing here? I've had my phone since October 22nd and this poor battery life is really annoying me. If necessary I can provide more information.
Thank You for your future help.
you probably have a defected battery, you ever considered that?
i just took 5 3mp pictures on my phone and the battery% didnt even budge. also 2 hours of music takes about 15-25% of my battery if that helps.
conclusion? your battery is defected
Solution? get a new battery.
BT has minimal effect, screen brightness is a factor, the lowest that you can accept is the best for battery.
Using an appropriate comm manager, turn off 3G except when you need it. 3G is the biggest battery drainer next to WiFi. Use it only when needed.
your battery life should increase about 20 percent after the first charge/discharge cycles; mine only lasted a day on standby with bluetooth on at first (100-15 percent), now i get about 3 days with bluetooth on (100-5 percent)
Hi guys,
Recently installed GPRS monitor that came with HTC tytn II... and on the main screen theres a little indicator telling you your battery life...
Mine reaches a maximum of 3:00... 3 hours?! is this normal????
can anyone shed light on this?
I usually have the phone connect to a laptop so I am not sure what my battery life is...
Joe
Mines starts with 1.5 hours but last few days......dont know why but this spb gprs monitor (the version that came with my o2 Stellar) used to work great, for some reason it does not work anymore......well the battery life indication bit any ways....
battery life is only an estimate when used in optimum conditions with only standard usage so i wouldnt worry about it too much unless you notice it drain as fast as it states
i think i read somewhere in the kaiser forum that sometimes with gps reciever turned on there is some abnormal battery power drainage .. Other day i was using google maps with gps turned on and my battery went from 100 to 25% in half an hour .. yikes. However haven't had it happen using yesterday and this morning. Battery at 80% currently no charge.
hope this helps shed some light.
peace,
sire
