I was really annoyed with my JJ as I did not know that the USB connection for syncing also charged the unit. When my JJ was new I was using the USB link for trying a lot of s/w and therefore was charing my JJ for short periods of 5 minutes a number of times. With my Exec I had worked out how to sync with BT. So I did what you shouldn't do I did not charge the Exec until the battery was down to about 20% and then for the next three charges i waited until the Exec was down to around 15% charge. Now after 4 full charges I find the battery of my Exec lasts much longer (my estimate is 20% better at least), especially now that I don't keep PIE running in the background. My Exec has no problem lasting a whole business day while the JJ struggled.
(note: the Exec uses a O2 3G SIM while I used a Vodafone 3G SIM with the JJ. I am not sure how significant the battery drain can depending on the 3G coverage/operation as I would say the Vodafone coverage is much better)
Its a Li-on battery isnt it? Not Ni-Cad.
This means it doesnt respond well to being almost or fully depleted.
Best to keep it topped off on the move if you're working longer hours just plug it in at the office or during the board meeting.
I can however tell you that the USB charging is pants on mine and unless you plug it into the mains it wont charge at a rate sufficient to not actually drain the battery.
This could be because I dont have USB 2 and am using a low power iBook.
But I found it didnt work well at all, best to use the mains adapater and stick to the USB for sync.
@gubbs, I am aware of the theory behind Li Ion batteries but I have now tested the idea of not charging fully the battery after purchase on my Nokia 9500 for which I had two batteries and I could compare the effects. The difference on the Exec battery is less than on my Nokia. I don't fully discharge the battery I just avoid the first full charge (why bother when your battery is say 70% charged anyway from new) and I avoid the frequent charges from the USB (my USB is fine, it really does charge faster than the Exec can drain the battery). I have also found my battery now seems to be drained less when using WiFi, which normally kills my PDAs.
hi. I've a problem with the battery page in "settings": even after 2 or 3 hours with wifi enabled, the indicator still show that battery is @ 100%... impossible, you know. what to do? i must change it with another one? i bought it 3 days ago...
not impossible...
the battery indicator as 10%steps.. it means that if your battery is at 91% it show 100%!
then if you are well covered with your wifi signal in 2-3h is possible to use only 9% of your battery...
great. grazie!
Battery Woes with 3200mah Extended Battery
I've purchased a 3200mah Extended Battery and the battery meter seems to be weird. The battery charges fine up to 100% and drains perfectly normal. However, at around 30%, the Low Battery Notification pops up and after around 2-3 minutes, the battery meters shows 2-5% of juice left.
Any suggestion on what I should do? Is the battery faulty or is something wrong with the calibration of the metre? I used to have this problem when using extended batteries with my IIs (Blue Angel).
UMTS Observation
I noticed when you connected the Universal to the wall charger, the signal strength will be stronger as compared to when the Universal runs on battery. I suspect the chip decrease its transmit power while running on battery so as to save juice.
Anyone can comfirm?
anyone have any ideas?
Where did you buy your battery? How long before you noticed this problem? Was it like that ever since you bought it or could it be another memory effect problem (plugging usb when battery is half full)?
I got my battery from a retail shop in my country. It states 'Dyna' on it, and i presumed it is legit, following a line writing 'Made in Japan, Assembled in Taiwan'. If i'm correct, the original battery is also manufactured by Dyna.
I first noticed the problem the very first time my battery drains. I did another test yesterday, and the battery drains linearly to 19%, the warning 'Main Battery Low' appears and it shuts down, not rebooting even when i press the soft reset.
However, when i plug in the AC source, the battery meter shows 2%. Where did the 19%-2%=17% of battery go to??
I doubt it is a memory effect, as I've done a few complete drain and the problem persisted.
There probably is an inherent problem with the battery... is that still under warranty? maybe you can have it replaced... good luck!
Does any of you notice the weird behavior of Athena Battery Meter. The meter only indicates the reduction of power bar for every 10% battery consumption. That is I only have 100%, 90%, 80% ..... 50% and so on of battery indication. There is no more precise battery level indication anymore. Does any of you have the same problem?
I noticed the same on my T-Mo Ameo.
yep, I noticed it too
Just like my Tytn; My one is the same
Hello,
Sir like many others, I too have a battery problem with my SPV M3100
The battery always shows it's status in the 10s. Which means like..
90%, 80%, 70%, ...
It never shows up something else then tens which is not really good.
The second problem. If the battery is 100% charged, I open WIFI in few seconds it will drain to 90% and 80% and then 70%.. It drains really very fast. I know that WIFI eats up the battery but not like 10% in 1 minute???
Third problem, If I keep my mobile 100% battery on stand by mode and I don't get a call. After 24 hours I go and see it will show and battery left 100%. But if I go and do a small task in mobile, it will drain like 30% in once. That is quite ammazing I have never played on music so can't say how much it drains while playing music on hands free.
Overall on standby mode, the battery lasts like 3 to 4 days. But if you use it for even a small thing, it drains really fast and battery was dead.
Please help, I think this all is not normal, Radio version can be the reason of this???
Thank you very much
Faisal
i have too this problem, if you find any way for solve this plz help me
I have the same problem..
Even when I go online with GPRS/3G/UMTS/HSDPA..
Does the problem come from the battery?
My battery has UTSTARCOM text on the battery. How about you?
EDIT : You need to flash a ROM with a 1% increment fix, it's because the stock/official ROM has 10% increment battery meter, I don't know why.. And my battery drains very fast because I have over-charging it.. I leave my Hermes charging overnight when I'm sleeping, and it leads to over-charging.. You need to unplug the charging cable when the charging complete ASAP..
I have the same problem on my Spv m3100. The power meter deplete at 10% increments. Unlike my HTC TyTyn 2 - Kaiser this shows actual units.
