That sounds very serious. You mean, if you press and hold the phone power button for like 5-10 seconds, it will not shut off the phone??
A PPC can't be shutdown :!: You can turn off the phone function, the PDA will go in stan-by mode. Reminders etc. remember?

Remove the battery and put it back in to totally shut it off (apart from power for the memory). :wink:

Not advised - the NiCad backup battery will go down completely, which shortens the life of the battery.
Stevedebi you got a NiCad backup? I've got a NiMH.
Anyway just as long as you put the main battery back in, the back-up battery won't suffer too much. The thing I cannot understand is why shutting down a PDA completely? My magician eats 3% battery-life in about 8 hours on stand-by. & I don't have the risk off losing data by fumbling with batteries. It's a small PDA, not a cell-phone.
Cheers, M

I said put it back in so that the memory wouldn't go.

ARGH! I can't believe I slipped up on that one, yes, it is HiMh. But the principal is the same. Those batteries are not meant to be fully discharged too many times.

Sorry, I missed that. However, would the device do a hard reset after this? I would think that either the device would resume working, or it would hard reset. Might be worth a try - set an alarm and see what happens after a main battery removal event.

Not true, particularly in the case of NiCD. NiCD batteries develop a charge 'memory' if you DON'T fully discharge them before recharging, decreasing the total charge they will hold.
NiMH batteries supposedly overcome this problem by not using cadiumm however in my experience they still can be affected to a small degree if they are cheaper lower quality NiMH batteries. NiMH hold a better charge anyway, the average AAA size NiMH is 6-700 mA/hours where as the average NiCD AAA is only 300 mA/hours.

I think that in the case of both battery types, charge memory is a bit of a myth. What happens is that the battery voltage suffers a little causing the device to think that the battery is losing charge very quickly, wheras it is really losing voltage slightly.

hi, i'm new to the boards. anyway, tried a search but was not successful. i am getting a cingular 8125 on monday and was wondering why they want you to charge the phone for 8 hours before putting the sim in? is it to optimize battery life? or will i be ok just getting started, i don't want to wait 8 hours. thanks!
i didnt wait 8 hours :S i put the sim in and turned it on

Phones use different chemical technologies, and some are prone to a memory effect or benefit from an initial "conditioning". It's easier for the Cinglar folks to tell you to charge it fully before any use rather than keep track of what kind of battery is in each device.
The Lithium Ion battery in your 8125 isn't susceptible to memory, nor does it need conditioning. Just start using it. What lithium ion batteries DON'T like though is becoming fully discharged...never let it run completely dead...it's hard to revive and can shorten its life.

I found this out the hard way, I thought my 8125 died because after being on a charger for an hour it didn't show any charge and the charging light didn't come on. It finally started to charge and now I am very careful to charge fully every night.

Excuse me it might sound dumb, BUT I had a year ago a Qtex 2020i and they said that if the battery ran out completely I would have lost all the data , kinda like a hard reset. Is this still an issue on the Hermes? I guess not, but I have to be sure, as I wanna do some power cycles to optimize the battery life. And this implies draining it completely....
So, is it safe for my data? Or I would lose it , like on the 2020 i?
Thaks
No it won't erase the memory.
Do current batteries still need conditioning? I've never conditioned one...
V
Yes I myself prefer to do that with all my new batteries (I used many many smartphones) so that I can achieve its maximum potential. At least it works for nokia batteries...
WinMo 5 has persistent storage so any device with it should be ok.

I think I read somewhere that lithium ion batteries don't have any 'memory effect' and therefore don't need conditioning.
Could be wrong though...
if u read even the nokia manuals...u will KNOW that you are wrong.... I dont do that to avoid the memory effect, BUT to get the maximum performace from the batery.

Nope. See http://www.batteryuniversity.com/partone-12.htm :
"Lithium-ion is a very clean system and does not need priming as nickel-based batteries do. The 1st charge is no different to the 5th or the 50th charge. Stickers instructing to charge the battery for 8 hours or more for the first time may be a leftover from the nickel battery days. "
It is not about the charging time.......It is about the power cycles... I am not very clear I guess..... Believe me , I am right..)
what is better for battery? To charge it often regardless of how much is left or wait until it's completely empty then charge it for 2-3 hours until it's fully charged...
You can do whatever you want, it doesn't matter even the slightest bit. Everything is either an urban legend or needs to be done the first time you charge the battery.
its bad to get it very low discharged i thought so i'd just charge it when ever you can
unless it's getting low during the day from stuff like
reading an ebook on the buss while listening to music on my a2dp stereo headset
I just charge it each night
but had it running a few days on standby with little usage

Spot on.
Usually every battery (better: akku ) will "last" longer if one doesn't use it
too intensive. I.e. fast and a lot of charges/discharges. So a lot of charges will harm your akku.
Li-Ion akkus have a characteristic which tells us to charge and discharge them
fully for about the first five times, otherwise your capacity will break down.
But as the Xperia has an Li-Polymer akku, there is no need for this.
Btw, to get back to the first point: Of course low usage is good for the akku,
but why buying an Xperia if not using it? But there is no need to have the Xperia
hanging at the cable when getting home if it would last for another day.
My two cents.

Is that short for "akkumulator"?
Of course, I didn't know if it was correct in english as well (in german it is),
but I was to lazy to write the full name always.

Ha! Good thing I speak German as well then .
i have a sprint touch.
and my problem with it is that the battery can't seem to charge.
also that battery with charge appears to have 0% and it will turn off in less than a minute. and there will be times that it will say 70% but will only last for about 5-10 minutes.
is this a problem with the phone itself? is there way to fix this?

Remove the memory card. It could be that it is somehow shorting out and drawing too much power.

Glad it worked out. It was a long shot, but it did happen to me once
I need some suggestions on how to calibrate the battery on my n4. It got miscalibrated when I did the update 4.2 to 4.3 and I haven't been able to calibrate it since then, a week ago.
I tried using battery calibration from the store but it didn't work, I tried charging the phone from 0 to 100 and it didn't work.
I remember I had the same problem 2 years ago with my Atrix and I solved it by wiping the battery stats from recovery, but now twrp and Cwm removed this feature and I don't know how to solve my problem.
Maybe it would help flashing all back to stock with the toolkit?
If you have any suggestions I'd really appreciate it.

Just the answer I didn't expected, and frankly a pretty useless answer, everybody knows that battery calibration doesn't improve battery life.
But I have other problems, like I turn off my device at 80% and when I turn it on it's at 77%. Do you think that's normal?

Either faulty battery or do the following:
1.Completley discharge N4
2.Charge fully(+2 hours after hitting 100&) WITHOUT disconnecting from the charger.
3.Repeat for better results.

To be honest, I don't know.
But if I would be you I would just let it charge while it's off(So the big ass white battery icon).

You mean off as in all the way off? If so, then that ~3% is being used when the phone boots.

I've had many phones, and none of them lost charge during the boot, at least not that many. I think that's the clear sign of battery miscalibration, I've had this problem before with another phone. Besides that, I've had a strange behaviour of the battery, for example I saw it lose 4% in 1 second, from 66 to 62 in a blink of an eye.

It's not that it's losing charge quickly, it's just the OS (or the hardware itself) doesn't always do the best job of reading it. There's not much you can do about that, and it's really not an issue unless you make it so by staring at your battery level all day.

Hi,
I'm having a similar issue. Phone rebooting to weird battery levels (not the %age it shutdown at).
Phone shutting down at 31% battery and rebooting to 0%.
I tried charging only to 100% yesterday with the phone ON.
Do I have to charge it even after it's charged to 100%?

I tried charging through the night and then discharging it completely and charging it completely again. I also tried deleting the batterystats file (even though I know it doesn't do anything)
So what do you suggest I should do? Get the phone replaced or get the battery changed?
I live in India and the phone is from Canada, so replacing the phone will take some time but I can get the battery replaced for around $20
Also my nexus is also showing +ve mA values while it's not charging, and the values are absolutely crazy, +268, +168, +1171 (in batter monitor widget)
Please tell me what I should do.

Before you replace the battery try to disconnect the battery's flex cable and reconnect it [after you charge to device to 100% and turn it off of course] check if its 'reset' the battery.
