Actually flash memory cards do not take up battery (ok, maybe just a bit). It is non-volatile, unlike volatile DDR RAM in PC mobo). Therefore, there is no big implication on the correlation between battery and memory card.

The biggest hurdle for wireless devices are batteries, whether is notebook PC, digital video/camera, h/p, mp3 player, etc. The size, how long can last, durability over risk.

SDXC will go into mobile devices in future, and that includes cameras, videocam, and h/p. Next generation h/p will be at least Full HD @720p, bigger screen, touch screen, etc.

Anyway, battery is still the biggest hurdle in technology. Processor, Memory, screen display, wireless technology, etc. all have advances many times, but battery is still lagging behind very far. Do you know how old already is Li-Ion or Li-Polymer technology and we are still using it today mainly ?

If there are cases of Li-Ion exploding on notebook PC and h/p, imagine if a fuel-cell h/p blow up

Or put under hot sun, which you may not be aware. e.g. Driving and put onto the h/p holder stuck to windscreen.

You want to a longer battery life at that risk ?

Yes, might as well a mini-nuclear power plant battery. It can last longer than your h/p
E.g. on marketing material: Buy a battery that can last you three mobile phones! No need to recharge for 25 years!

But then, no. People will use it as mini-hand grenade mini-nuclear bomb during riot, instead of throwing rocks/stones.

How accurate you want ? What's the difference if you have 20% or 30% battery left ? Or 60% or 80% ?

Or you are interested to know you have 24.5% or 24.7% battery left ?

Go read from battery-university website and google on Li-Ion battery and technology. That's how Li-Ion behaves. If you have time, then proceed reading Ni-Cad, Ni-Mh, Li-Polymer, etc. and its distinctive features (advantages/disadvantages).

Nokia and other devices, including notebook PCs using Li-Ion behaves the same way. e.g All the notebooks when left idle, between 60-100%, it says can last 2-3 hours. Then when drop to <60%, it goes down very fast.

Anyway, sometimes I get p!ssed off with Li-Ion battery indicators also. When check, shows full bar, but is actually just a bit above full bar. Go outside halfway, the battery drop 1 bar. Then already know the battery will not last as long as I want.

So, nowadays, I charge daily Mon-Fri in office, even when it drops one bar. Sat-Sun sometimes do not charge, or charge 1 time only.

My battery still strong after >1 yr. Not yet degrade too much. Original authorised Zitron set.

I'm not aware of any 3rd party Li-Ion battery with higher capacity. If original, that would be more expensive than original authorised nokia battery. Maybe 1.5x-3x more expensive due to small volume manufacturing.

If there are 3rd party brands, normally from China, I will doubt the quality, the charge retained and the purity of Li used. The purity of metal/alloy used will affect the battery charge and life-cycle. That is why certified ones are much more expensive, due to purity of the metals. Like gold 999.9, 999, 915, etc. Another similiar ones are Uranium isotopes. Normal purified uranium are only good for normal nuclear reactors. You will need highly purified uranium for weapons grade material.

This also explains why cheaper AP or fake battery will not last long after charge and also will wear out faster.

Li-Ion has a general 500 times life-cycle charges. It is not advised to drain until complete zero or too low. When it starts beeping low-batt or a few bars, you can start charging. There is no memory effect or need to charge/discharge cycle.

Official count, yes. But with advancement in Li-Ion and better purity, this will have lesser effect as counting as one cycle. There are some arguments with a person keep on plug-in and pull out the charger for 500 times with a completely new battery.

Therefore, it is not recommended to plug-in charge, then pull out with incoming calls/sms, then plug in again. If continuous do like that several times a day, over 1 year, it is time to replace the battery already.

Normal AA rechargeable are Ni-MH or Ni-Cad. Those have about 800-1000 cycles.
e.g. Energizer, Eneloop and GP are Ni-MH type rechargeable batteries. How come some brands can retain the charge longer ? Again, it is due to the quality of material used -> metal/alloy purity.

Well, 3rd party manufacturer normally produce Ni-Cad (very seldom nowadays) and Ni-MH. Try look if the 3rd party camera batteries are Li-Ion ?

1. The price is too cheap to be original. -> Less Li metal/alloy purity.
2. I suspect is Made in China. "5 Year Limited Warranty" (sic) -> should be 5 Years ?

Without going further on fake/real, I think no harm trying, but becareful about possibility of leaking/explode. Although original battery still have chance to explode, but is lesser.

But my view will be:
1) Initial few weeks/months of usage, the battery will perform as good as original.
2) After that, it will degrade very fast on a full charge.
3) Also, it won't last as long compared to original. e.g. after 1 year, see which one die first
4) Hopefully, it is actually same factory for the original OEM manufacturer. Then you are lucky and the performance will be quite similiar to original.

Finally, all my SMS (about 10,000+ now) kills my Phone Memory (C:\).
Note: Not the RAM or Memory Card (E:\)

236kB Free Memory left only
But actual 10k+ SMS Messages takes up 5MB only.

I can't open or run anything without insufficient memory, please delete message errors.



After I delete 4k+ SMS, I free up 17MB. Guess Nokia FAT for very small files are not efficient. Just like PC FAT16.

Delete another 3k+, Free memory = 15MB.
Still deleting now...

Added on April 9, 2009, 2:26 pmOk, finish deleting 90%+ SMS

I free up 46MB.

Added on April 9, 2009, 2:36 pmWait. I just realised Messaging includes the Email boxes

I got 3 mailboxes with 200-300 emails there

Clearing again...

GPRS MMS Activate Setting For Hotlink DiGi Celcom, Useful info!!

I tried to change SMS (Messaging) from Phone Memory to Memory Card. Halfway copy -> Insufficient Memory. Please delete some data... I give up after several tries.

Maybe when I upgrade Memory Card to 16GB, I'll set to Memory Card and start collecting again.

Open the SMS message
Options -> Add to Contacts -> Create New
Enter the name, details, etc.
Done to save it.

It's a bug. Nothing can be done directly/easily. I also have a few SMS like this, already in Contact, but SMS still show the number

<6 months. About 5+k received, 5k+ sent.
5k x 5 cent = RM250

About 6 months delete about <2 hours in between work. Click delete, while wait... do work... then delete... wait... work...
