Battery problem!!!

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.

Kaiser Battery Life seems very poor compared to Hermes

Hi,
I have a TyTN/Hermes that had reasonable good battery life unless it was connected to a HSPDA network and then it lasted around half a day.
The Kaiser (which is only a week old) has a pretty poor battery life, even though there is nothing running.
It was fully charged, I am connected to a 3G network with a steady 3 bar signal and have just made 2 calls lasting around 28 mins in total. The battery is showing 72% left. Bluetooth was on for both calls.
Based on the Hermes, and both phones having the same 400GHz processor, I don't think this is normal, can anyone explain?
Thanks

Why don't you do a search on battery on this forum before starting yet another Kaiser battery life thread? THere are at least 2 others with posts in the last day with people providing tips and experiences with the Kaiser battery.

Whats your battery life?

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

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?"

Battery life

i flashed my Diamond 3 times since i bought it 1 month ago.
i started with 1.34 ita, then 1.37 ita, 1.93 ita and now i'm on SwiftBL-WWE-Diamond-ROM-v5.6.
Diamond is my work phone, now i am in holidays so i do not use it all day long but it is turned on for eventual calls.
Since i put 1.93 and still now with swiftBL i notice that the battery life is shorter. At now, in stand by mode, only keeping it turned on, the battery lasts less then 5 hours. With 1.37, making calls sendig sms life was around 6hours or more.
I must charge my phone 2 times a day and put for another charge near midnight before go to bed for all night long. Batteries like charge cicles but now im thinking this is too much stress for diamond battery.
do u think it is broken? how long is your diamond phone battery life?
i probably buy another battery and a car charger so i can charge it in any place, but i would be glad for more efficency.
anyone of you knows how much thick is extended battery?
thanks for answers

There are pictures of the extended battery in the accessories forum - pretty much where you would expect to see them.
That does sound like odd behaviour to me though for your battery. If I don't touch my GPS, make a couple of brief calls and send a few texts, whilst keeping in 2g mode, I expect to see about 40hours from a charge.

I'm experiencing a similar behavior with 1.93 ROM and 1.00.25.05 radio firm.
I'm currently wondering if S2U2 is the cause.
_Mystique_, do you use S2U2 ?

I use S2U2 with mine - I have been using the new radio and ROM from Dutty.
Just in standby with push mail on the battery lasted of 36 hours from friday. sundays charge lasted only 24 with the same usage? apart from 10 mins on teeter

i had about the same issue - i was charging it about twice a day to keep it going. i took it back to phones4u in here in the UK - after a bit of discussion and getting an error code from Orange - they gave me a new one - and its about 50 times better! the battery lasts much longer and the signal is better! my theory is that i had a faulty aireal or something - it had terrible reception, and because of that, more battery power was used trying to get a signal... But i might be wrong!

Hi
I had this issue as well, until I have stop sync my calendar
I do not understand why, but for now I am not sync it

i have a Diamond branded "TIM", and also my battery last about 10 hour without using the phone, always in standby.
I tried switching off the phone module and the battery last about 40h.
So for sure the problem is the aerial/phone component.
I will send the mine to htc in warranty, because i think that 10 hour in stand by is not the normal behaviur of this phone.
also i tried 2 spare "chinese" battery, from ebay, but all the results are the same.... so for sure aren't the battery.
Bye

Question:
I'm going to get my Diamond soon. How long the battery must be charged for the first time? 3 hours or more?
Why it is not good to empty the partially charged battery and then refill it to 100%?

i have partially solved the problem
yes, i use s2u2, but the real problem (for me) is Kaspersky Mobile. Closing it im experiencing 100% plus battery live: i ended a complete charge at 14.48 at now (21.52) i am at 50% battery.
So the problem are the running tasks. This time i closed kaspersky and s2u2, then i will check if i can close some SwiftBL default task
i am in 3g mode (i've switched off hsdpa), bt always off.

i think that is normal that more battery is spent with phone mode enabled.
i think that a realistic battery life target is a work day.
on ebay there are batteries (10$) and craddles...

Beware of these cheap batteries.
Especially for GPS, that seems to need genuine batteries to work well.
Other topics already deal with this.

im i dreaming this diamond reality or what

when i got this diamond phone last week the battery performance
was bad serving me with less then a day worth of power where i
had to buy a second battery.
now that i have been off from work for a few days (3 days) i finaly
had the chance to cain this phone properly eg. flipping wifi on/off
through out the day listening to shoutcast, lenghty periods trying
to setup LAN, listening music while out on the road and checking
emails, looking on the net, yapping on the phone and sending txt messages.
to my supprise the battery seem to be holding up pretty good. now it
appears to be holding out till the end of the day where before i had to
carry two batteries now i think i can get away with carrying just one.
here are my stupid questions
1, does htc batteries get better performance after multiple charges?
2, did i have a semi faulty battery and now a miracle has happend?
3, am i just dreaming that the more i use the longer the battery stays on?
today i charged the bat. at 9am (ish) and now its 3,45pm. i still have 3 bars
remaining im supprised as from before a few days ago this was not the case.
im using the daimond with no mods and standard battery.

suprised!

hiya mate,
I am going through the same thing. First day I got the phone and battery was awful about 4 hours it lasted me! very shocked. but it is holding out.
I did charge the phone initially for about 12 hours as specified but don't know if that helps.
what i tend to find with new mobiles is that you have to charge fully and then DISCHARGE FULLY the phone numerous amount of times to get it to perform to the best of its abilities. I don't think its anything to do with HTC batteries, just the fact that new batteries have never been used and need to learn!

you are half right. this battery life is improving if you keep charging it but it is not advised to fully discharge them.
the fully charged-fully discharged method was for the old batteries with "memory".
somewhere in this forum, in the trinity forum somebody experimented the two ways of charging-discharging the battery. the conclusion was that it is better to charge the battery anytime, any occasion u have.

Indeed, the battery's performances (and this is applicable to all common batteries) will increase by time until it reaches its max capabilities.
To gain performance, the battery has to discharge and charge very frequently, or better, continuously. I don't really know how the Diamond manages it (meaning if the battery is full, will the device still get power from the battery if it is plugged on, or will it drain power from the cable. It could also drain from battery if it is fully charged and charge it in the same time, or it could simply always take it from the cable and charge the battery in less time)
The reverse is also true, meaning if you don't discharge/charge your battery frequently enough, its performances will decrease by time.
Also, if your battery discharges and charges all the time, it's lifetime will be longer than a battery that is only used once in a week.
I don't know if I made it clear, lol.
By the way, don't think that if you keep charging your battery you will end up with weeks of battery, there is a limit and it is 850mAh on the stock battery, if I remember correctly.

thanks for the tips some say discharging is good and some say dont.
all i know its 8:35pm and i have only used 1 bar from around 4:30
which now leave me with 2 bars. im jumping for joy because normally
by 6pm ish the battery would have already died.
with all the hammering today i cant believe it only took 2 bars in nearly
12 hours and thats with no extra charge from the psu and only 5 usb
connections to the pc to sync and add files totaling 2 - 5 minutes
on each connection.
now i can officially say this phone is "DA BOMB"
time to sell the e90 and e65

The thing that kills the battery on this phone above everything else is the GPS - knocks it out in 90minutes or less. If you were having fun (even for a few minutes) with it in your first few days, this might explain it...

GPS?

yeha that would explain it but the thing is I haven't even installed TomTom or any other GPS related app!!! weird. but i've had it for about 4 days now and battery does seem to improve slightly on a daily basis.
