2 day users - Optimal battery settings? - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

Wanted to know from those getting 2 days out of the mini pro, what are your systems settings to make this possible.
1: I have my screen to less than 50%, can only still manage a day.
2: Do you guys turn off 3G HDSPA?
3: Does wifi use more or less battery than HDSPA?
4: Any of you using a blue tooth headset?
5: Any specific apps to kill?
6: Any special battery conditioning done? If so steps?
7: Do you guys have exchange e-mail on? push or pull?
The battery meter is showing more than 50% going to the screen.
Good that it seems I don't have an rouge apps and the wireless doesn't seem to take up too much battery, but a let down that I can't get more than a days worth of battery.
Found some decent battery recommendations here

Why are you trying to make your battery last 2 days? Do you not have access to a charger everynight?
Also I do not recommend you 'kill' any apps, due to the nature of Android. If you 'kill' an app, it's very likely it will just start up again, using more CPU cycles than if you just left it idle. This is especially an issue if you are using an auto-killer.

1. set 40%, add widget at front wall for fast switching (to 80%)
2. turn off mobile network (data), add widget at front wall for fast switching (to enable)
3. -
4. no
5. using system panel lite to clean and root uninstaller to remove apk at system app (currently memory at 230M-240M)
6. restart phone 3 time per day, use 1800mAh, charge phone when >5% energy, to 100% (45minutes), turn off while charging is more better.
7. no - exchange e-mail running at background processor (any unwanted background I will kill or remove; currently only 3 apps still running)
use dark theme/wallpaper for energy efficient (low brightness) and use earphone to listen music

Why kill mem? Its there to be used. Free mem is useless mem.
The most drain=screen,wifi,gps,maps,bt

I noticed maps seems to stay on a lot. Anyone know how to make sure it stays off when not in use?

I'm not sure what value this message is supposed to provide. I've seen folks post that they can get 2 days or better out of the phone, if so what's wrong with wanting to do the same?
Also note that there are times when it's inconvenient to charge and I'd like to defer charging. I'm pretty much out of juice by end of day the work day, but would like to have a few more hours of battery left, having the phone on the charger all the time isn't always convenient.

I understand if your phone is starting to go flat then you might want to start conserving battery, but if you have the ability to charge it then why not?
I agree with r33p. Using a task killer is possibly one of the worst things you can do to try and save battery. Using less memory does not save battery at all.
Also im not sure if this is true, but using a dark theme does not save battery as the backlight is still on, but screen is just 'hiding' it to create the black you see. So if anything it uses more battery.

I tend to keep a widget on my home screen to turn off data, wifi, and bluetooth. I turn them on when I need them, turn the off the rest of the time. As long as you aren't doing heavy internet browsing on your phone, you should be able to get two days use out of it.
Hopefully we'll get some custom roms for these things so I can justify rooting my phone. Then I'll uninstall all of the stock apps I don't want, both to clean up my app screen and to hopefully stop some of those background processes I don't need.

I must agree. Using a dark background does not save battery. That only works for oled or amoled based screen like the galaxy s series. Also they're right, don't use a task killer. Terminating apps just consumes more battery.

i can last 1,5 day without charging.
if i dont do anything special besides reading mail and answering a few whatsapp messages i do about 3-4% an hour. if i dont do anything at all, like at night, it uses 1-2% an hour.
1.screen is 35%
2.i have 3g on. sometimes i put it on 2g only
3. i dont know but i turn off wifi en bluetooth whenever i dont need it.
4. i use bluetooth in my car tot connect my phone with my car. unfortunately this uses a lot of battery by being just connected.
5. i kill the popgames, this uses a lot of battery
6. most times i let the battery go empty and only then start charging with the powerconnector, not through usb with a computer.
7. i dont have exchange but imap push email and another account pop3 which connects once every hour. i use the app k9mail
last weekend i did 2,5 day but i was abroad and didnt have roaming data and turned off wifi en bluetooth.
i did 1% a hour except when i was driving and connected my phone to my car.
but still 2,5 day

Does 2g only save battery over wifi and 3g? If so, is it sufficient for e-mail?
Mike

---

I normally put all of my most used widgets on the front page for quick access

---

3g or wifi pref. 2g is painfully slow.
Yea and forget appkillers,delete the apks or freeze the unwanted services.
The tricky part - what (not) to delete.

You need root to do that, however.

yes 2g saves battery
i was told that because of the continues switchting between G, 3G and H the battery consumes a lot of energy.
when you put it on 3g only or 2g only it saves battery.
becasue i dont have 3g everywhere i go i put it on 2g so that i can make calls everywhere i am.
if i need to do some things on the internet i switch it back to 3g.
2g is enough to recieve mail and whatsapp messages.
my mail wont come in as fast as wifi or 3g but that doesnt matter to me.

How do you set it to H only? Is this via WCDMA only?
I'd love to drop the bloatware, but want a clean root option that won't affect functionality.

I have about 2 days. Currently I'm on 82% 12h since charge. My experience:
1. I keep 3G switched off most of the time when I'm outside. Only if I really need the speed for uploading a photo or update an app.
2. I keep Wifi running all the time at home.
3. I have disabled Location&Security both Use network and GPS. These seems to drain battery even if maps and latitude is disabled.
4. In the carrier settings I have disabled automatic mode and going for manual mode and selected my carrier.
5. I always use the back button on any app until I reach the home screen before locking.
My idle drain is about 1.5-2%/h when I'm at home with wifi. Outside with 2G it's draining a bit more and with 3G it uses insanely much battery.
I have lot of push services running (fb/g+/twitter-notifications, Whatsapp and gmail + an Exchange account)
I have also noticed that the battery calibration is a bit flaky. From time to time I run the phone until it dies (sometimes at 8-10% but sometimes at 30%). Then I'm unplugging the battery for a minute, plug it back and charge and it have calibrated and doesn't die at 30%.
Another thing I have noticed is that I can't get more than 4172mV charge. The battery should be able to charge to 4200mV.
Two good apps for monitoring battery usage is BetterBatteryStats and Battery Monitor Widget (which is more than just a widget)

do you guys charge till it reaches 100% or just till it turns green?

thats one other discovery I have made.
when the phone says 100% it's actually still charging (can be seen that there is a charge indicator at the battery and also can be seen from Battery Monitor Widget)
Another thing is that when it has reached 100% it starts to drain battery until it reaches 95% then it starts to charge again. (nothing uncommon with that) but the phone still shows 100% so sometimes when it's unplugged it can actually be at 95% (but starts to countdown from 100%).
Battery Monitor Widget can alert when it's actually fully charged with a notification.
