Greetings,
I guess this question is not new, and is covered in several other topics, but nevertheless I will like to ask by what means Folio battery can be saved and how battery life could be improved?
Regards,

I'm not sure if what I suggest is good, but my tips are:
1. Don't use unnecessary widget
2. Don't always turn on Wifi and bluetooth when you're not using them
3. Don't always charge the battery when it's not about to drained (I only charge when the battery level is below 10% or even more extreme as 5%...)
And I think best way to maintain a good battery life is to use DC adapter (with battery taken out) when you're near to a power socket (at home for example). Only use battery when you have to move around. That way you can reduce the recharge cycle and don't need to worry much about battery life
By the way, just a quick check, how long can your Folio battery last in a full charge? (with all settings to highest, like brightness, wifi + surfing net?) Mine can last for about 5-6 hours.
The Samsung Galaxy Tab 10.1 is about to release its 2nd-gen tablet with battery rating about 3 times higher than our Toshiba Folio tablet...
I read that putting tablet into flight mode(and thus deactivating some phone features) can help.... If wifi is needed -one can just re-enable it in settings...
Can anyone comment this ?

It helps A LOT. Wi-fi seems to drain this device a lot even tho there's not much data transfer. Battery use reports insane percentages for wi-fi on my device at least.
And no need to go to settings, just create a widget for wi-fi activation
Also :
- use a non-animated background
- kill the apps you don't need

I want to flash to a newer ROM, but then i'll lose my battery-calibration. I will have a couple of days a real bad battery prestation and my battery will also not get better of it. Doens anyone know how to back-up the calibration and how to put the settings back after a flash?

That is not possible since the ROM has to be trained to the battery. It is really very simple. All you have to do is run the battery dead on the new ROM and then let it recharge and it will be calibrated. There really is no calibration data so much as training the ROM to know your batteries empty state versus full state. The fastest way to run it down is turn GPS on as well as WIFI and BT and leave them on. Your battery should be dead in less then half the day.
Also please do not double post. We see your post and if no one answers then no one answers.

i agree on the first part but disagree on the rest
running the battery dead isnt good for Li-Ion batteries, and for running down the battery dead faster would actually put a lot of stress and heat (if youre connected to data and running very heavy apps that uses either wifi or data, or even A LOT of CPU) on the battery as well, heat is a no no for the battery, just let it down by leaving the backlight on and turning off auto standby, works for me and its going good
read some of this on the bottom, might help you

BATTERY SAVING TIPS
The first few days
• Immediately after flashing, you will probably observe very poor battery performance. This is due to the charging circuit having to reset itself.
• The battery meter will not settle down and give accurate readings for a few battery cycles. Give it a few days.
• For the first few battery charging cycles, try to charge to 100% with phone off and then allow battery to drain down quite a bit before recharging. This is so the meter will calculate drain well.
Recommendations
• Make sure you followed all of the flashing instructions to the letter. Especially the part about the hard reset.
• Backlight is set to high. You might want to change that.
• 3G is on by default. Recommendation is to turn it off when you are not surfing the internet.
• Don't drain your batery all the way down until it dies. Not good for these types of batteries.
• The GPS sucks the battery dry. If you want to keep track of yourself, consider something like GPSToday that only wakes up the GPS once in a while.
• Maybe you don't really need aGPS enabled. Disable and check GPS lock times and battery drain.
• Applications that run from the storage card consume more power so install oft-used or background-type applications to main memory.
Troubleshooting
• If your radio does not match your rilphone.dll you can get crazy bad battery drainage. Use the recommended radio or spend some time working out a good combination for your phone/carrier/location/usage.
• Check to see that some application is not still running in the background. Check, do not assume. USe the full Task Manager application.
• Check to see if the screen is still on when you expect it to be off. Soft reset can fix that issue.
• Some radios work better with some carriers and locations. Asking everyone to tell you what radio to use may not give you the best answer. Be specific about your situation.
If you have tried all the above and still can't get over a day with moderate use, you may actually have a bad battery. Try getting a new one that is made by another manufacturer.

I'm not sure that it helps (I do it anyway, lol), but I think it's a good idea to flash with the battery fully charged (and maybe plugged in, if you flash off a card).
But when the ROM is trained, it has to save tha calibration data somewhere in it's system? And when you can find dat data, flash a new rom and put that calibration data back, you do not have to train your phone anymiore, right?
If you flash your rom, You should be sure toloose preety much everything of your settings, as far as I know. And so on you wont be taking anything alng (as long as you havent a good backup-tool with you), ...just adjust the settings another time (If they are too many, tell me what you did, maybe I can help my own sttings ^^ (Hate the battaryusage aswell, ...)
hi,
I don't know if I'm the only one that has this problem, but the TG01 battery drains very fast (compared to other devices I have, using teh smae services i.e. 3G, push mail and BT), it takes almost 14-18 hours then needs to recharge.
also i wanted to switch off the 3G or the push mail, but the Comm Manager doesn't allow this.
any idea?
Yes this is a major issue with TG01 unless you buy (as I did) an extended battery from Mugen.
To save battery :
- turn off automatic baclight settings and reduce backlight intensity
- use NoData to disable data connections
- reduce CPU speed unless you need power (DivX playback for example)
Or buy a 2600mAh Mugen battery... My TG01 last more than 2 days with intensive use (with 8 hours divx playback with Bt used with Bt headset, about 30mn Internet by 3G and normal phone use, and backlight settings and CPU at full power).
Mugen batteries increase TG01 thickness and weight except the 1300mAh one.
I have just ordered the 2600mah battery as well as the normal battery that comes with the TG01 just doesnt last 12 hours without needing a charge.
Small price to pay for a £150 phone though, these sell on play.com for nearly £500.
My battery don`t take 18 hours or so to recharge, you might need to let the battery go flat and then fully charge it several times and see if that helps, if not, take the phone back for a new one, might be a faulty unit or battery.
Thanks Howell for the advice, but i can' switch off data, nor 3G.
the Wireless manager does not allow to do so.
can you please advise how to reduce teh CPU speed?

To switch off the data you need MoDaCo NoData. You have to register but its free and has a good TG01 forum.
To change CPU speed go to Start\Settings\Power Saving Setting, then select power saving or set up user customisation to a lower setting.
I really like this phone but the battery drain is terrible. I have that verizon extended battery in it(2750mah) but even with that the phone will lose about 10% battery in about 1 1/2 hours during non-use and roughly double that if im browsing the web.
I have Battery Doctor and Juice Defender running at all times and disable anything i dont need to have running. Also, for some reason Battery Doctor does not display my current battery status accurately so i use a basic battery stat widget to know exactly how much battery is left.
Does anyone have any recommendations on what i should do? Apps i should use/not use? Oh and i do keep display brightness down and have done a full cycle charge.
Thanks!

I don't know if this would help/is recommended, but I decided to bump charge mine once. It seemed to help me out, but opinion seems to be split on whether it's good for the phone or not. I also use only friends and calender widgets, and about 4 toggles (airplane mode, gps, wifi, mobile). I generally turn off mobile network where wifi is available. I have been off the charger since 8 am and am at 83% with light use (a few texts, a little facebook, etc). I do use Watchdog lite (to watch for misbehaving apps) and autorun manager (to tweak what runs on startup). I should probably also mention that I have the stock battery.
Turn off 3g manual in settings.
Make the Radio do 3G Only.
Put the phone volume half way.
No vibrate when receiving a text and audio play after the text.
No vibrate feed back when touching the home,menu,back and search button Which can be found in settings>sounds>haptic feedback. Uncheck it

I have a stock battery.
I use the battery monitor widget to keep an eye on battery use and rogue apps. If I go over 50mA at idle, there's something that's running when it shouldn't.
I also have wifi sleep mode after 15 minutes of idle. And I keep blutooth and gps off. Also LTE only since i have excellent coverage here.
And i use Tasker to turn on airplane mode overnight (turns off all radios) and also silence all alarms, lights, vibration...
I get through about a day and a half of normal use no problem. Once cm7 is out i imagine i will get 2 or more days no problem, as it tends to idle at less than 10mA which would be a dramatic overnight difference.
I get about 7 hours of battery everyday through medium usage and my battery drains quite a lot when I am revising and listening to music. I have a 1900 battery instead of the stock 1650 and it does improve battery life but is there anything else I can do? I find it a bit stupid that my battery drains so much when I'm just listening to music!
I am running CM9.
Whats the signal strength like in your area? Aside from the screen (put screen brightness down), 3g seems to drain my battery most in weak signal areas, where the signal bars are continuously on 1 or 0. I put my 3g / data off and my phone can easily go hours before any drop in battery percentage, I got 4 days battery life with 3g off using it sparingly or wifi when i could to check my emails. Only other thing i did was calls and texts, but that was just as a test.
But i like to keep data on, and gps, all the time. I often get 4 hours screen time and approx 24 hours battery life with my 2000mAh Samsung battery.
Aside from that, last time i checked cm9 was a battery drain, may have moved on a bit.
the only real way you can save battery "during use" is with some restraint. Ie turn brightness down if screen is on, listen at lower volumes if it's playing music. The more voltage it's using the faster it drains. So less brightness or volume output = less power used.
7 hours is around the average use for battery life savy users around here. Even with the extended battery I'd say your right about on the money for battery use (based on what I assume you do and don't know at this stage). But there is certainly room for improvement .
Now before I go on, you probably won't notice any significant difference to battery life during use from these steps. My only hope is that in-between use it'll save more power, and squeeze out a bit more usage time for you.
First/easiest thing would be go to check if it's sleeping properly. Just don't use it for say an hour, then go to the battery monitor in settings. Check the screen on and awake times, they should be almost idenical. If there are several awake records in between screen on's, then you have a problem.
If you use sounds like unlock sounds etc, go turn them all off.. this was/pretty sure still is an issue in CM9 (causes audio_out1 to continuously wake up the phone from deep sleep and drains the battery like a mofo). Also getting rid of facebook (if it's installed) will help.. it loves waking the phone for no obvious reason.. even with every form of sync, background data, and mobile data in general turned off .
^^ you don't have to do that step but I'm pretty confident you'd have to anyway, so it's just easier to do it straight up. Then you can look for other problems.
Next, install "better battery stats". If you like to support developers, you can quickly buy it off the market. Otherwise it's free here if you search for the official thread.
Reboot your phone, then leave you phone for an hour or two, then check out whats happening in better battery stats. I'm not going to pretend I unerstand what half of the stuff it bangs on about is, but I digress. Select "since charged" and then check each different tabs of data (partial wakelocks, kernel wakelocks etc). You are really just looking for anything that stands out as a red bar basically. small amounts aren't a real worry/bound to happen. If it's bigger than say 1cm long, it's probably an issue. Then it's up to you to find out what the app/process is doing the damage . So either google or the better battery stats thread will be your friend at that stage. It was obvious what is was for me cause it said facebook but you might have a different experience.
Hope that helps. But the only way that's going to make a real dent would be trying to use it less.. lol.
Oh and if possible, turning on airplane mode would save a bit of battery in use. And of course the obvious ones like turn of wifi, gps, bluetooth, data, auto sync, soft key backlight and anything else you can turn off
Just do it what i say .. Download the full version of app. called juice defender from play store..install it and then see the magic by yourself ..i have been using the same ..it almost double up the battery backup through its advance settings.

Hello,
my name is Udi and I have a new Transformer Prime. I wanted to ask how do you maximize the battery life? from all aspects - is overcharging right? is full discharging right? etc.
thanks!
The single biggest improvement will come from going into the advanced WiFi settings and setting WiFi to turn off when the screen is off.
Also you should run using balanced or power saver performance modes unless you plan on running an intensive app like a game.
Aside from that normal things like turning down screen brightness, disabling GPS and setting your accounts to sync every hour (or more) rather than every 15 minutes can do wonders for extending battery life.
