Is it necessary to charge my phone for 8 hrs?

Is it really necessary to charge my phone for 8 hrs before the first use? I just got my phone and i dont know whether or not charge for 8 hrs or just use it right out of the box. thanks guys!

It's not 'necessary', your phone won't brink if you don't do it.
However, if you condition your battery - charge for 8 hours on first use and then drain it until it's dead, and repeat 2 or 3 times, the battery will have a much better life and useage time (in my experience). This is because all batteries have memory, even ones that say they don't.

Are you sure what you are talking able? Li-ion don't have memory effect. And if fact "A stand-alone Li-ion cell must never be discharged below a certain voltage to avoid irreversible damage." (quote: http://en.wikipedia.org/wiki/Lithium_ion_battery)

so its not necessary? im confused what did everyone else do when you first received your phone?

I work in the business... I'm sure.
First off, wikipedia is not the most reliable source. Second, your phone won't let you discharge your battery that far, it will shut off long before the battery gets that dead. Lithium Ion batterys can lack the 'memory effect' (effect being the keyword), but they do have memory.
Either way, no need to get up in arms about it. Just charge your phone up all the way, use it till the kaiser tells you to recharge, something like "Replace or recharge your battery to avoid data loss". It's like 10 or 15 percent. When you get there plug it in and charge it all the way up.
You arnt going to hurt your battery as posted above. Correct, if you get way too low you may have issues (why batteries go dead when they sit for a long time), but your kaiser won't let that happen. It will shut itself off first.

Thanks for the info. If they don't have the effect, then what's that memory going to hurt us?

I'm not completely sure what you are asking... but...
The memory won't hurt you. True, you could probably take it right out of the box and use it however you wanted. The memory just helps tell the battery know when it's completely full (to switch to trickle charging if supported by the application), or when it's dead and in danger.
I'm too lazy to try and explain it, so I copied this... I should have refered to it earlier as "digital memory" earlier because it's not at all the same as NiCAD memory which is what most people understand - hope this clarifies.
From - http://www.batteryuniversity.com/parttwo-34.htm
"Although lithium-ion is memory-free in terms of performance deterioration, batteries with fuel gauges exhibit what engineers refer to as "digital memory". Here is the reason: Short discharges with subsequent recharges do not provide the periodic calibration needed to synchronize the fuel gauge with the battery's state-of-charge. A deliberate full discharge and recharge every 30 charges corrects this problem. Letting the battery run down to the cut-off point in the equipment will do this. If ignored, the fuel gauge will become increasingly less accurate." ...
"Batteries with fuel gauge (laptops, *cell phone {added by me}) should be calibrated by applying a deliberate full discharge once every 30 charges. Running the pack down in the equipment does this. If ignored, the fuel gauge will become increasingly less accurate and in some cases cut off the device prematurely. "
Hope this helps. There is a reason why the manufacturer recommends this. Battery performance as well as the accuracy of your gauge can somewhat depend on this sort of conditioning. This is the reason you may see your battery gauge go up after a restart, or when you charge your phone it may say 90% one second and 100% a few later.
Regardless, this is a crash course in batteries.

tool to test battery?

hey is there a tool or software with which i can check if my battery is broken or if it has full capacity? my battery lasts only 2 days, this sucks!
if i use a 1600 mah battery, will the percentage be displayed correctly? or can the tytn only handle 1350 battery and i have to take the 1600 out and put it back in?

two days is not bad. mine wouldnt last more than 24 hours due to the way is use it. i have bluetooth on all the time, wifi on nearly all day and my display is set to the brightest mode and i turn it on very often. i dont expect the battery to last longer than 24 hours.
its a agood habit to keep pumping electricity into it every now and then

Yeah, I need to charge every night. It's not the battery per se, it's just the Tilt/Kaiser uses a lot of power, especially if you check email often, use BT and wifi a lot (GPS too eats up power). I don't use push mail at all, so that helps stretch the battery (I just manually check my mail periodically throughout the day).
I think many people would say if you are getting 2 days on a full charge, that is great!
Personally, I just got a second charger for my desk at work, and have a car charger in the glove box. If I know I'm going to be away from those for a lengthy period (weekends say) I have a AA battery powered emergency charger (from pocketsolutions.com) I can take with me.

Battery empty as fast as the speed of light

I know those Pocket PC devices drain their power very very quickly, but when I wifi for let's say about 5 minutes on some websites, my power is drained like 10 percent maybe. Is that extreme or 'normal' for the kaiser?
On the other hand I must admit that when I do nothing with my kaiser it can last very long without recharching.

Which rom and radio are you using? These devices are not exactly renowned for their great battery life (the cost of 3g and hsdpa), but there are ways to optimize them...

PDACORNERultimate. But I also used a HTC P4350 earlier, and it was all the same with the battery life , just wondering how I can measure what battery is better because I have 2 tytnII's until tonight, so I was wondering how I can measure what the best one is .

ALL batteries lose the ability to keep a charge as they get older. Any battery over a year old should be highly suspect.
Get the Tytn II that appears newer, then get a BRAND NEW battery for it

A new battery cured my fast discharge problem. At the time Amazon had the best price on batteries.

I've observed with my TyTnII (1yr old) that the battery drains faster from 100% to 70%. However, it retains charge from 70% to 0% for a longer time.

A 10% change on the meter means nothing. To evaluate your battery life/drain, start with a fully charged battery and run it down completely until the PDA switches off.
As said above, the percentage reading is approximate and won't always go down in a linear way. It can go down from 100% to 30% in one hour, then take 3 more to go down to 0.

I think you are using the wrong charger. The charger u are using is nog strong enough. I had the same problem. You need the original charger.

Charge: slow until 65%, then jumps to 100%?

Lately, I noticed that when charging my tilt with the charger, it takes forever to get to 65% and then in almost no time, jumps to 100%. Is that normal? Does something need to be done? Do I need a new battery? If so, what's recommended?
Separately, when using WIFI, it uses over 400 mA -- that's outrageous.. Any way of improving that, while still being able to stream audio (ie power saving settings may be an issue)?
What's a good battery meter to help debug things?
Thanks

I have the exact same deal going on with my battery charge. Started happening not too long ago. With the stock ROM and with hyperdragon III ROM, I always see the jump.
I'm not sure what the problem is but I figured it was a false charge in that the battery's capacity has really lowered from the original 1300mAh. Also, thus why your batter drains much faster than it does (so does mine). If anything, it's probably just a normal battery problem which could probably be solved if you got a new battery. I haven't tried (yet). The battery life went from 3 day's of casual use with some data connecting here and there, to 1 day and if im lucky, a day and a half.
Hope this helps out a little. And if anyone has the real solution, do tell. Thanks.
Regards,
K

I had the same problems. Took forever to charge. Battery life was horrible. Could only make a 3 minute phone call on a 100% charge before the phone would shut off. Ended up being the OEM battery was done. Lasted about 1 year on heavy use. Bout a battery/cradle charger from Amazon that came with an extra battery. Also bought another 1600mah battery. Both of them work great. No more charging problems.
Simple answer, like us, batteries die.

I too think it's a faulty battery (which may still be covered under warranty). It's always a good idea with the TyTN II to have at least one spare battery for long trips etc (I have the original and 2 spares as well as a cradle which recharges spare batteries). The O/P should try another battery to confirm that works normally and if so and the original battery is still under warranty, contact HTC/The supplier to see what can be done. IF they need the phone (and I've never tried claiming on a battery under warranty), make sure it is fully reverted to 'as from the factory' status using all official ROM/Radio/SPL before sending it in.
Edit: The o/p could also try cleaning the battery terminals (using a cotton bud soaked in contact cleaner) to make sure high electrical resistance has got nothing to do with it.

Diamond consumes a lot of power

Hi there,
just a short question. I've update my Diamond to the naked version of the official 2.03 ROM (can be found around here) and the radio 1.09.something (that quad band radio with supposedly good battery life and gps reception).
After a clean hard reset I only installed powerguard to measure the drain as a reference (so I can compare what installations of some programs might do).
I was shocked to see that the drain was 167mA out of the box with 3G already disabled, no WiFi or anything running. Is that normal? The auto brightness kept the level at around 5/10.
I was able to bring it down to 64 by disableing auto brightness and lowering the level to 2/10.
When the brightness dimms completely I get 53mA.
Are those values that are normal for a Diamond? Those 60-70mA with lower brightness would at least give you some time to work with the device but at ~170mA the battery drains like nothing and would be flat in less then 8 hours (the 1340 battery that is). You don't work with the device constantly but the drain out of the box shocked my quite a bit.

Yes, thats our beloved Diamond alright.

Well, around 60-80mA are workable and much better than the close to 200mA out of the box. But I wonder where HTC got the claim for stanby usage from. Standby (with display off, just sleeping away there) my Diamond consumes 15mA. Using the standard 900mA battery would keep the Diamond on the net for 60hours. Using the 1340mA battery this increases somewhat to 90hours.
The official claims are in the 300+hour range though for phone standby times. That would mean that the drain would be as low as 3mA. Where on earth did HTC measure that???
The 1340mA battery should give me 2 days of Diamond before needing to charge (mainly standby, some data tranfer, little WiFi and GPS) and that's not much worse than my old Eten X500 was able to do with its 1500mA battery.

with extended battery and 3g off, i am able to get a weeks (7 days) worth of odd phone calls, a fairshare of txt messaging, a little bit of gprs, no gps. If i turn the 3g on the extended battery lasts around 3days with a fair bit of usage.
I think its just the phone, no matter what powersettings you have its just power hungry. I went through many different power settings, roms etc to finally find something not as hungry and what free'd up ram

Lets do some math here -> 7 days would mean roughly 160 hours. With the extended battery (we're talking about the 1340 one do we) you're average drain would have to be as low as 8-9mA - including the spikes when you do some work. I think that's highly unlikely given the fact that the diamond usually does never fall below 10mA just sitting there on standby. Usually I see values of 12-15mA during that state.
Doeing work once in a while and making some calls, I'd say my average would be around 30 giving me barely two days of usage.
I simply rely on the base 900mA battery as backup so far. It's light to carry around and when my 1340mA one is done I quickly change them and get another couple of good hours. At home I recharge both. Battery changing is done very quickly on the diamond and the rubberdized back of the 1340mA set holds the stock 900mA just as well (so I don't have to carry around two back covers). This way the 900mA stock one also gets trained and does not sit idle in the case degenerating over time.
And since the 1340s are relatively cheap atm (I paid 25 Euros for one including the back cover) I may end up simply getting another one of those. Those two and the stock would get me through the work week and on weekends it's recharging time.
I can't really remember how the old phones did it. My first mobiles would last two weeks on standby and my first Qtek would achieve 1 week. They did not have larger batteries did they?
The Diamond is not particularly power hungry though. I ran some test on the HP messenger (914C that was) of my coworker today and this one has a large battery (close to 1900mA as far as I remember) but struggles just as much to get through two days, maybe even more so then the Diamond as the 914C seems to drain even worse. And the oh-so-hip iPhone 3G (we have three guys at work with those) barely gets through a single day. Those poor souls always carry a charger. Guess modern devices are just hungry for electrons.
Another question is about the "training" of the battery. The usual consensus is that the battery need a couple of cycles to reach its potential. But who does this work mathematically/electronically? The drain values don't get lower as they are system depentend and the battery does not generate more capacity then the 900mA or 1340mA. So where does the extra runtime come from???

Some more observations...
1.) There has to be something wrong with the PowerGuard app. Either the measurements are rubbish or the Diamonds can fall into some sort of deep sleep when not used for a longer time that PowerGuard is not aware of.
I recharded my 1340mA yesterday morning (that was over ~40hours ago). I used it through two full working days now with normal usage for me (2-3 shorter phone calls a day, some download using Edge and some WiFi and some 15min of GPS each day). Now I'm at 40% battery. That would even get me a third day of usage like I need.
Not sure if the power drains measured by PowerGuard are higher than reality or if the Diamond goes into some sort of deep sleep when not used for a longer time with even lower drainage then the 12mA.
Whatever I'm quite happy to see that the 1340mA will give me two full days of heavy usage (for my standards) or three days of standard usage.
2.) The Diamond drain is relatively good compared to other devices. We did some more tests today at work and especially the HP models drain their battery much faster resulting in shorter life then the Diamond - and they have 1900mA batteries.
We did equal tasks on the devices and the "drop per task" on the Diamond was better then on comparable modern devices. Some older ones are way better though including older HTC models that some of us still use.
