I haven't tested them thoroughly because I usually have my prime where I cannot charge it, but now that I have a dock I was wondering is there really a difference between "Normal" and "Performance" mode? If so how will this affect my battery life when docked in the keyboard? Will I still get an entire day (5-9 hours) of power using out of it? (Pandora, Youtube, Netflix, Forum browsing, and Web-based Homework)Thanks for any input. Also is there anything I can do to boost the performance as well? I am rooted.

yes there is a difference. its default mode is set to balanced mode @ 1.2Ghz. this is the best of battery and performance. if you want your battery to last extra long, put it on battery savings mode @ 1Ghz. you want ultimate performance, put it on Performance mode @ 1.3Ghz 4 cores or 1.4Ghz on a single core. the different modes does affect battery life alot and performance. but you can have prime on battery savings mode and still stream movies and such with no issues. The biggest key to battery life is brightness. that will determine how long or how fast the battery drains.
if you unsure just leave it on default balanced mode. there will be no task that it can't handle and still give you good battery life. even performance mode gives good battery life but drains at a faster rate since you getting maximum performance out of the prime in that mode.
More Kick
And too add a little more kick to your device here is a simple Overclocking app that works very well. I've used it since I've had my TP (a month or so) and it has never caused issue one.

I gather the OP wants to know more about the battery impact than anything:
Checkout this comparison: http://www.anandtech.com/show/5175/asus-transformer-prime-followup/3
That was during Honeycomb but the modes are the same, they just have a different name. Normal == Performance
As you can see there is very little difference in the battery life between balanced and performance.

Actualy since the latest update, wifi causes about half or more of all battery drain.

Hi everyone,
I'm wholly on NDT MIUI GINGER 2.3.7 MULTILANG SUPPORT V9.0[SiyahKernel2.4.2] ROM. I have SetCPU installed but not really sure how to use it for optimum results.
I'm quite a heavy user, spending a gd 2+hrs worth of music listening to and fro work, at least half of workday of internet browsing and social networking, plenty of messaging and I have my emails on regular push. Currently using this ROM, I get a day's worth of usage before needing to charge at night before going to sleep but I wish to improve it further.
My SetCPU now is on scaling smartassV2 ( i have no idea which to use or what exactly it does, i used it because it sounds cool), everything else on default.
Anyone here can point me in the right direction or guide me on the best settings for my usage?? I see Profiles and Voltages but have no idea what to put in them.
Thank you for any assistance!!
you can try to undervolt and underclock. try to undervolt by decreasing +- 25mV to see how much you CPU can stand. have look here for battery saving tips.
http://forum.xda-developers.com/showthread.php?t=1234264
as for the governors you can learn more from here http://wiki.rootzwiki.com/CPU_Frequency_Scaling
also you can try to buy an extended battery such as the original samsung galaxy s2 battery 2000mah. i am pretty sure it will make a difference.
thanks mariosraptor,
after a day or so on smartassV2, UV of -50mV on each voltage tier, main profile running at 200-800mhz i can say there's is a slight improvement, not much but better.
In the past, when I unplugged from 8am, I will have to charge again by noon. It's not toally drained but I would have used it to around <10% battery before charging. Now I can pull thru till around 3-4pm with the same heavy usage so that's a good few hours' real-world improvement.
I would have gotten the new extended battery if it had been available locally earlier. I bought myself a portable battery pack long before Sammy put that battery on sale. Even so I will prefer to lengthen the lifespan of the phone battery a.k.a charging less often and still get the best out of my phone.
SetCPU really helps but I do not expect much since I suppose no amount of tweaking can ever beat heavy usage. I will share my SetCPU settings here later on. Cheers
You are welcome.

I know there are some people experience battery issues, but I've experienced none. Running on the latest build .15, This is after leaving it unplugged over night at 100% to then moderate use all day (Youtube, Email, Browser, Pinball, Sprinkle, Music, Camera, Video Cam).
I'm happy to say the least.
Cripes!!!
Is that with or without the keyboard attached?
Without Waiting for the price to drop a bit before I buy it, it will drop soon I'm sure.
The battery is so good on this thing it's not even an issue. I never check battery stats or anything like that.
Can go through a day no problem, always on performance mode.

I am sure that that battery statistic includes plenty of standby time, since it is unlikely anyone would be playing pinball for 24 hours
I get similar battery life with my Prime. A day and a half or more with moderate use and normal downtime (like when I am sleeping). I am pretty sure I could leave this thing sitting in standby mode for weeks and still come back to it and find usable battery life remaining.

same here and i just plug it in when i get home.
On update .11 I was getting 2 1/2 days (tablet only) with the same moderate-heavy use, always-on WiFi. About 4 days on standby.
Update .14 I guess is doing better than .13, but I only get 2 days with tablet+dock and about the same usage as before. Haven't tested standby.
I've found battery life to go like this on .15, with auto brightness (which usually finds a good level for me) and Balanced battery setting:
1. Around .375%/hour on standby. That seems excellent to me, particularly considering that I keep wifi on and everything syncing in the background. I can't imagine getting better standby battery life unless I turned everything off, which I don't want to do. I like it that my Prime is up to date when I wake it up.
2. Around 7.5%/hour when doing things like ebook reading, VERY light browsing, etc. That also is excellent, meaning I can use the things for ebook reading for over 10 hours. Can't ask for more than that. Note that if I read outside in direct sunlight and Super IPS+ mode turns on, battery life is cut SIGNIFICANTLY. That's to be expected of course, and it's just as much of an impact as I imagined.
3. Around 15%/hour for heavier browsing, ebook reading, watching video, casual gaming, etc. That's a little less than I'd hoped, coming in at around 6.5 hours total.
4. Around 30%/hour for heavier gaming (e.g., Shadowgun). I'm not sure if that's good or bad. Seems like it's excessive, but then again this IS pretty intense gaming.
I can help these scores a bit if I run on Battery Saver mode, which will work for all but heavy gaming. Funny thing is, according to CPU Spy mine barely ever pushes 1300MHz or 1400MHz, no matter what mode its in. It spends most of it's time at 1200MH, in deep sleep, or in the lower (100MHz-400MHz) range. I wonder if Nvidia still has some tuning to be, and if performance and battery life can still be optimized a bit--it seems to spend TOO MUCH time at 1200MHz when that kind of speed doesn't seem necessary, and TOO LITTLE time at 1400MHz when that kind of speed would be helpful.
Wow! Great battery life OP. That guy named Ickii needs to see this thread. He created a thread on his prime getting bad battery life.
Same results here though. Great battery life in balanced mode and very heavy usage.
Anyone use this (or the custom ones) built into the Note?
Are they effective or is Juice Defender a better choice?
Regards,
Stu.
i rooted mine and dropped the clock a little under 1ghz using set cpu and i get two days of light use. a day and a half heavy use. i didnt notice a performance difference either.
Just Rooted mine and have seen battery life definitely decrease.
I am going to drop the clock and hopefully get a little better battery life.....
I hve been using my phone on power saving mode from 2 days to save battery and to hve more life out of it. I wana ask tht it is ok to use it continuously on power saving mode forever??
Any ideas??
No problem in using power mode all the time. It's a feature Samsung enables to save battery
Yep. Can't see a problem except the expected performance downgrade etc.

Personally I hated the power saving modes in every smartphone i had cause it affects performance. I will buy a spsre battery and a charger. If you are ok with the performance in power saving mode you should use it!
Enjoy your phone to its maximal potential. Don't let the battery saving issue to disturb your user experience.

My phone doesn't decrease in performance with saving mode enabled. It is always fast.

Not the case with mine, I notice a decrease in performance. It most likely under clocks the CPU...
In regards to the original question, no there is nothing wrong with leaving the phone in power saver mode. In fact you could probably argue that its better as the phone creates less heat.
Ideally I'd like to overclock mine
Well there is no such thing as saving power without sacreficing preformance. (unless you undervolt it or use more power effectient drivers)
But you should be ok running in power save mode all the time, although I do question why you bought a top of the line smartphone then. I think you would have saved more power (and money) buying a lower end phone.
It does govern the cpu. You can uncheck it. I leave mine checked.

Truely speaking i cant see diiference of even 1% in comparison to power saving and normal mode. Any one knows y battrey depleting though good but at same rate in both modes??
juice defender app does a good job for me. i use the basic settings but you can tweak it to save more battery.
Power saving appears to cap the clock speed at 1.0 GHz rather than 1.4 GHz and it may also disable cores, too. Most of the time it feels just as responsive to use. It is less snappy for some apps and benchmarks quite a bit slower, but I feel I'm splitting hairs as it still feels quicker than my last handset.
I see two days of moderate use with Power Saving on. I don't quite see two days with it off, but the difference is probably not statistically significant and the device is still new.
Power Saving
im using a power saving application on Xperia S ... is it okay to keep it working all the time??
thank you ....
ButterMaker: first of all, wrong forum, also battery saving apps are known to interfere with androids way to handle memory so I would say no

Yes, should not use battery/ram optimization apps. They interfere with androids core system.
I uninstalled all these apps after trying and researching. They eat more battery then they save. I only use battery stats apps to keep a log of battery drain.
Now I easily get 40+ hours on my S3 with moderate uses.
So, what exactly does Power Saving mode do? Have seen reports for the GS3 that it lowers clock speed, others that say it disables a core, so obviously there is no consensus as to what it does. It's not that I need it, this battery is beastly, but I am curious as to exactly what it does.
When you click power saving in the settings (instead of just switching it on) it tells you, but it dims the screen and changes the browser to a blue hue to reduce battery drain and also turns off haptic feedback, it also limits your processor speed to 1.1ghz instead of 1.6ghz
sent from my Note 2
I use it at night alot because it dims the screen. i notice about 30% longer battery life...i just recently netted 50hrs of battery life with 7hrs screen on. still had 12% remaining!
