Spare Battery
If you have an old K800/K790 or K810 lying around the batteries will fit the Satio. They won't last as long, I think they are about 850 compared to 1000mAh of the Satio, ...

The battery in K800 is also a BST-33, i.e. exactly the same battery type as in the Satio. However, battery technique has evolved since K800i was introduced, so if you buy a new BST-33, regardless if you intend to use it in the Satio or in a K800i, it will have 1000 mAh capacity. You can probably still find BST-33's with lower capacity on the market, especially at low price stores or places like e-bay, but they are old versions even though they are genuine SonyEricsson. BST-33 fits in several SonyEricsson models btw.

@altemyr, that makes sense. I was surprised when I got my Satio to notice that it was a BST-33.

The BST-33 battry on my K800i, which is the original battery that came with the phone, is labelled 950 mAh. I cannot see the version number however, since the text is worn off, but it may say BKB 193 200/1 R2A.
I have a T700 at work which has a BST-33, 950 mAh, BKB 193 200/1 R2B
My Satio has a 1000 mAh BST-33, but the label does not contain a product number.

But I still believe that the batteries are fully compatible as long as they are labelled BST-33 and are genuine SonyEricsson, even though the one in the K800i has seen better days, the charging capacity is not very impressing anymore.

i agree i don't think here'd be any problem. The mAh is a measure of how many milliamps the battey can deliver in an hour before running flat - so the worse than can happen is you won't get as long out of a 950 bst33 as a 1000 bst33

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.
