I use my W880i's battery in my Satio all the time, or at least i did until my sister borrowed my W880i and hasnt returned it 2 months later !!
I use my Satio heavily and it never gets me through a full day when i do. Thats why i keep a charger at home, at work, in the car and often carry the USB cable with me if im going somewhere where i will be able to USB charge it.
My Satio tip: sell it and buy a N8. Heh

oh ok seems like i dont have a faulty battery. If i watch a movie, browse a bit of net, and listen to music, in about 4-5h its empty.. I dont really use it now so it keeps me 2 days, but sunday when i aint home but at my cousin and listen to some music + 1h net browsing and it drains out fast. So it is normal :/

watching a whole movie consumes a lot of battery i think you can't really expect to watch a whole movie without being plugged into a charger, and still have much useful battery life remaining. the problem with satio is not how much power it consumes but the fact the battery is only 1000mAh. Still, a whole movie sucks a lot of juice. I regulalry watch about 30-45minutes of movie, 30-45 minutes of music, 15-20 minutes of talk and browsing 20-30 webpages in a day and don't have to charge until I go to bed. That's pretty usable battery life.
If I talk more than usual during the day, i have to charge in the afternoon if i want to watch movies on the way home (or risk having a very low batt before i get home - i like to have a good reserve available)

Just remember that the 900 mAh or whatever the label says, is what the battery was capable of delivering when it was new. A BST-33 battery from a 5 years old K800i that was used daily is probably not capable of keeping more than half of that charge. Battery do loose their capacity after a couple of years' intensive usage. I think I remember reading the warranty limits for a laptop battery, they only guaranteed its functionality and capacity for one year or something like 300 fully charged / fully drained cycles, whichever came first. |

This is not so critical with Lithium batteries but when they start to die they more or less go straight away.
1. Lithium batteries don't suffer memory affect and don't need to be conditioned to attain a full charge cycle. Your lithium batteries will be capable of holding close to the full charge they had when new most of their life, but will rapidly lose their ability to charge fully near the end of their lifecycle.
2. Lithium batteries have a shelf life and the battery will expire once it reaches the end of it's shelf life whether the battery is used or not. "Conditioning" the battery will have no effect on either the batteries life-cycle or the charge-cycle.
This has been true of all my li-on phone batteries - they work perfectly until one day I go to use the phone and it won't start up at all - battery completely dead. This is what happened to my K800 battery (which is why I don't have it anymore). However my K750 battery is still working fine!
Generally Li-on batteries have a shelf life of around 3-5 years.

Here's wikipedia entry on advantages and disadvantages of lithium batteries:
Advantages
*Wide variety of shapes and sizes efficiently fitting the devices they power.
*Much lighter than other energy-equivalent secondary batteries.
*High open circuit voltage in comparison to aqueous batteries (such as lead acid, nickel-metal hydride and nickel-cadmium). This is beneficial because it increases the amount of power that can be transferred at a lower rate of current.
*No memory effect.
*Self-discharge rate of approximately 5-10% per month, compared to over 30% per month in common nickel metal hydride batteries, approximately 1.25% per month for Low Self-Discharge NiMH batteries and 10% per month in nickel-cadmium batteries. According to one manufacturer, lithium-ion cells (and, accordingly, "dumb" lithium-ion batteries) do not have any self-discharge in the usual meaning of this word. What looks like a self-discharge in these batteries is a permanent loss of capacity (see Disadvantages). On the other hand, "smart" lithium-ion batteries do self-discharge, due to the drain of the built-in voltage monitoring circuit.
Disadvantages
*Charging forms deposits inside the electrolyte that inhibit ion transport. Over time, the cell's capacity diminishes. The increase in internal resistance reduces the cell's ability to deliver current. This problem is more pronounced in high-current applications. The decrease means that older batteries do not charge as much as new ones (charging time required decreases proportionally).
*High charge levels and elevated temperatures (whether from charging or ambient air) hasten capacity loss.Charging heat is caused by the carbon anode (typically replaced with lithium titanate which drastically reduces damage from charging, including expansion and other factors).
*A unit that is full most of the time at 25 °C (77 °F) irreversibly loses approximately 20% capacity per year. Poor ventilation may increase temperatures, further shortening battery life. Loss rates vary by temperature: 6% loss at 0 °C (32 °F), 20% at 25 °C (77 °F), and 35% at 40 °C (104 °F). When stored at 40%–60% charge level, the capacity loss is reduced to 2%, 4%, and 15%, respectively.
An interesting fact to consider here, if storing or not using a battery for an extended period of time it is advisable to discharge to about 50% which will lengthen the shelf life. (20% loss per year for a fully charged battery, versus 4% loss per year)
What the wiki article is saying is that a batteries charge capacity reduces irreversibly each year, but I've never found that to be the case - the battery charges almost to full until almost at the end of it's life, then over about a month or so rapidly declines. According to the "Battery University", it's the charge that is lost - so if you put a battery on the shelf and don't use it, charged to 60%, it will lose 20% charge per year - so if you buy a battery that's been on the shelf for three years with initial 60% charge, it will still have 28% charge (3x20% of 60%).
This is also true of my experience.

pretty common tips but thought I'd include them (I think these apply to s60 generally):
*#62209526#
WLAN MAC address
*#2820#
Bluetooth MAC address
*#06#
IMEI
*#0000#
Firmware version
*#7780#
Soft reset (asks for phone lock code; 0000 unless changed by user)
*#7370#
Hard reset (asks for phone lock code; 0000 unless changed by user)
*#92702689#
Total Call Time
