My phone seems to easily die within a day with it being used.

I've since turned off wifi scanning, turned off bluetooth. Turned the brightness from 50% to about 30%. I've also swtched off 3G/UMTS.

Screen timeout is set for 30seconds.

Is there anything I'm missing that would improve battery life?

I have seen a 1500mah battery that I'm going to order for the phone (aftermarket)

For a smartphone with such a large screen charging the phone once per day seems normal to me. Smartphones like the Satio kill their battery quickly depending on usage. Theres not much you can do really. Turning Bluetooth off will save you a fraction of standby time - you wont notice it. You're already doing what helps to save power. I wouldnt buy a third party battery though. My suggestions are:

- Make sure battery is charged fully before use
- turn off wifi
- turn off Bluetooth
- turn off 3G/HSDPA if you dont use it
- turn screen brightness down to minimum
- turn off the light sensor
- close apps rather than pressing menu to get out of them and do not leave them running in the background
- install a task manager to close any processes running which are unecessary
- turn off vibration or screen tap noises
- turn off the accelerometer
- turn off GPS (by default mine was on, therefore was attempting to get my location constantly)
- install themes to phone memory
- reboot the phone daily
- if you do not wish to use the phone feature, turn on flight mode
- set screen timeout to 15 seconds or less
- enable auto keylock

The firmware update is the biggest improvement you can do - as there were things going on before that could kill the battery in 5-6 hours when doing ABSOLUTELY nothing (usually when I was asleep!).

The screen brightness matters only if you're always using it for things like messaging, web, videos etc - for calling it's blank anyway thanks to the proximity sensor and in standby it's off too.

Turning off 3G probably doesn't make that much difference these days, especially for standby. It also means losing out on anything like web browsing or email downloading - and is more hassle than it's worth really. There's no quick way to toggle 2G/3G, so if anything I'd want to lock it to 3G now to save it switching bands.

Wi-Fi off - yes, Bluetooth probably uses very little power at all when not in use. Leave it on unless you have absolutely no need for it at all.

GPS doesn't seem to be the battery killer it once was, but quitting Google Maps or the like instead of leaving it run in the background is still advisable. Very easy to forget, on account of the multitasking nature!

To be honest, if you want maximum power on a high-end phone, you won't get it. If you turn everything off, you may as well have a basic phone without these features at all... a basic phone with a monochrome screen will last 10-20 days and still work just fine for voice and text!

Or leave the phone in the box.

My advice; do the firmware update and then get used to charging each day. If there's a need for more power, buy a portable battery powered charger or a spare battery that you can keep in a wallet or bag. Be wary of third party ones claiming huge capacities - there's only limited space and I'd want to see someone testing these first. Since the 1990s, third party batteries have often turned out to be way below the performance of a standard battery, let alone some amazing thing that has 50-100% more power.

I recently had similar problems on my brand new c902. Left on standby in its first week on 3G the battery lost alot of charge without doing anything. After a few discharges and full charges its a great battery now. But Symbian Smartphones are prone to poor battery life even if using a higher capacity battery.

All smartphones have poor battery life compared to none-smartphones. This is something most people who move from one to the other do not realise. Ive gotten into the habit of charging my smartphones every night before bed. If i forget i pay for it the next day.

Which is why i keep a spare charger in my desk drawer at work !

My previous three SE phones have BST-33 batteries and I bought one extra, so using only one phone at the time I have four spare batteries. That should do it for a day of heavy use.

But honestly speaking..the 1000 mAh battery is really to low for power hungry phone such as Satio. So there's nothing you can really do about that

The 1320 mAh battery of 5800 is quite adequate.

Agree 1300-1500 mAh should be the minimum capacity for a smartphone. Continuous YouTube download/playback can drain my W995 battery in just a few hours - a Nokia E52 with its 1500mAh batt lasts 6-7 hours (and that's with a faster but more power hungry CPU).

Its handy for me in the hotel i work in. Guests leave so many chargers in lost property we have a wide varied choice of them to use every day

Having discussed this, i noticed my previous phone (N95 8gb) had a 1200mAh battery compared to the lesser Satio battery. Yet i notice no difference in standby time. In fact, i'd say the Satio lasts longer.

Possibly the Satio has better power consumption efficiency and the capacity of the battery is only part of the determining reason for being so hungry.
