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 Batterylife

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).

Severe and strange battery issues - Please help!

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.

My Opninion about the battery

Hi all,
I just wanted to tell my opninion about the standard (900mAh) battery.
I heard a lot of people complaining about the battery, I also complained about the battery. But that was only the first week when I got the phone. After a week or 2 the battery became better and better, every time I charged it up. Now I use the phone 3 days without charging , compared to the 1 day I could use the battery in the beginning, 3 days is very good. Things what I do in those 3 days are: Internet (umts, hspda), Reading RRS feeds, taking pictures, listening music. So the battery is quite good. And I am happy now!!
Unlike the good battery, I am going to buy a new battery (1350 mAh) Imagine how good it then will be, then I can use even more like 5 days.
I just gave my opninion because, before I bought the Diamond, I heard rumors about the battery, that was almost a reason for me not to buy the Diamond. Still I bought it, and I can't confirm these rumors.
THE BATTERY IS PERFECT, and the phone is great too (especcially with the v1.93 rom)
So don't listen to those rumors, and give your own opninion, I give this phone a 9!!

I have had my diamond a week, and i found that the battery would be flat before i got in from work (8:00-5:00) and thats with very moderate use.
Last time I charged it up, I didnt use the charger that came with it, but instead used a standard wall mains to usb charger (came with a blue tooth gps) and its now on its second day, and it has only lost 3 cells on the power info screen.
have been using the phone more than normal only thing i have done different is install the tweaked com.manager to turn 3g off (dont get 3g in the are im at any way) and it seems to be great now.

where did you find this tweaked manager?

just use advaced configuration tool. Go to Options, Comm manager and add '3g' to the tick boxes.

I've made a few tweaks with Schaps and TF3Dconfig and my battery has excellent life now. I think it does take a few days of charging and discharging to settle down but I can now go days with reasonable use

In my opinion it also depends on WHAT you use to charge up your battery. I mean, whether you use the stock charger, or 3rd party charger.
I bought a 3rd party charger (http://www.momax.net/products_detail.php?cid=2&scid=1523&brandcat=82&pid=11134) and the output is only 400mA, when compare to the stock charge (where the output is 1A), even thought both are fully charged, I observe that the one using stock charge, can last longer than the one charged by the momax one.
Anyone has the same experience?

I already posted my thoughts.
My MDA lasts longer when charged with the stock charger (5V , 1A) as opposed to charging from my PCs USB port (5V, 0.5A)
Thank you for confirming what I was experiencing.

Yep same here, the battery last around 2-3 days. Turning of around 12pm and back on around 8am.
And yes charging form the outlet takes less time and seems to give a better more solid charge.
And yes the tweaks help very much.
Hey guys we are just getting to know our Jewel.
Shes a friendly gal!!!

I just watch one movie in Coreplayer and the battery becomes half empty. The battery is a joke. Sorry, I love this phone, but HTC really dropped the ball on the battery.

Now it depends on the length of the movie doesn't it?
Another thing with ion-lit bats is that they require very controlled charge and that explains a lot of the problems experienced. I also believe the initial charging is important to respect. I charged mine for a full day initially, and noticed that it used all night for charging for a while (even the indicator was on full).
Today it was used for a few calls, had it on BT sync with my PC for a couple of hours, and used iGO GPS for 20 min, still leaving it 3/4 full. I could wish for more battery capacity - one week would be nice - but as long I only need charging at night I personally see no major issue. I have an extra battery or two as I tend to use the phine as MP3 player on long haul flights which I certainally prefer to the thicker backcover and the 1800 mAh battery.

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!

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 syupid questions
1, does htc batteries get better perfomance after multiple cahrges?
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.

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.
