I am getting decent battery life, but it seems strange that Setting Profiles would use 1/3 of it.
Any one else experience this? Or know a solution?
Thanks
when I change profile on my Nexus S and go back example default or any other profile my ringer for notifications stay at the lowest setting. Very strange, maybe because I'm using CM7 nightly.

Not sure what to make of your situation; however, out of curiosity, when you select Settings/About Phone/Battery use and click on "Settings Profiles", does a new window pop up to provide further info and if so, what info is provided?
Best Regards!
yes, right now it has used 24% of my battery, I get a new screen that says
Battery used by application 24%
Force Stop Report
CPU total 5m 7s
Keep awake 2h 47m 43s
stop or unistall the app
app info (button)
I just changed it to turn off the widget after a change, increased the rule scan periods location etc.
charging to 100% (or so) and pulling the battery to reset the clocks to see what I get. im not sure if this is recent with this device or it has been doing this since I got the nexus. I didnt see it on the Epic or Evo.
thanks
As some of you have been complaining about your Infinity's poor battery life, I thought we should start a thread on getting more out of its battery. I invite you all to share your experiences, hopefully we could come to sth helpful together.
Perhaps when the development's carried on further by more XDA developers, we can split this to stock ROM and custom ROMs, as probably the latter will have more of these already included.
1. Arguably full charge and discharge does nothing good on modern Li-Ion batteries and it's rather advisable to keep it balanced - discharge a little, don't push it with charging all the time (however in case of the Infinity, as with many other devices, the charger will just stop consuming energy after [almost] fully charging your device). There is one reason for doing a few full discharges and charges however - so that the battery monitoring apps/widgets can learn more about your battery's life and power consumption.
2. Monitor your battery life and monitor it wisely (don't use power-consuming apps and widgets). I personally like Battery Monitor Widget, as it gives you mA and % / hour (either drain or charge), which is pretty cool, as you can see how much your usage exhausts your battery in real time. This way I've found out that switching the WiFi off while reading books actually gives me battery drain closer to 10%/h than 15%/h etc. You can see some other in this apps thread. Try different apps and see what fits you best. Don't rely on system battery usage stats, see what other apps show us and what apps and processes drain the most of your battery, show most wakelocks, etc.
3. Use as low power mode as you need (administered most easily through ASUS/Android notification bar on the bottom of your screen). There are three power modes:
power-saving (keeps your CPU at 1 GHz according to some apps, 500 MHz according to others) <- can give you up to 2 additional hours
balanced (keeps your CPU at 1,5 GHz)
normal / performance (keeps your CPU at the highest speed - in stock kernel 1,7 GHz for the 1st core and 1,6 for the others)
You have to try these for yourself. Most games run well on balanced, but may sometimes need the performance mode (keep in mind that overheating your CPU and GPU may cause the clocks to actually slow down). You may also find yourself happy with the power-saving mode, which really helps your battery to last longer, but I've noticed issues with some apps while running it (problems with pdf rendering, for example), as it probably changes more than just the CPU clock speed, but also the system behaviour. I hardly ever leave the balanced mode, mostly when curious about benchmark results
There are also different CPU governors in Android/Linux kernel, which you can change if you are rooted, but perhaps leaving the default "interactive" one on should serve you well (you can also try "conservative", but it has been argued it doesn't save your battery so well in the long run).
(if rooted) You can also use CPU management apps like SetCPU, create your custom profiles or use the default ones according to your needs (for example ).
4. In ASUS setttings switch on both power-saving options at the very bottom of the list (WiFi and dock deep sleep [the former is the same as choosing "never" in WiFi advanced settings]).
5. Keep the screen brightness as low, as you can. It's better to adjust it manually through the notifications bar or a widget than to switch auto-brightness on (some recommend LUX app, personally I had problems with it trying to outsmart me when I was doing some manual changes). I like to keep it around 30-40% indoors during the day and 0-10% at night.
6. Switch WiFi off when you don't need it, unless you need it on constantly.
For me, it sometimes also helps organise my work too, when I don't get constant notifications or when I'm not eager to browse the web all the time, when just reading something and taking notes.
7a) (if rooted) Make your device fall into really deep sleep...
Add these to your build.prop file (see the thread on tweaking):
ro.ril.disable.power.collapse=0
pm.sleep_mode=1
7b) ...and make it scan for available WiFi networks less often, for example every 180 seconds (same as above):
wifi.supplicant_scan_interval=180
8. (if rooted) Switch off all the apps you don't need that auto-start on boot with a program like System Tuner.
(f not rooted) Use auto-killer for the apps you don't need (if rooted you can do the above two together as well).
You can also deactivate unused apps (settings -> apps -> [select app] -> deactivate). Remove bloatware, too (see the first few posts).
9. Adjust your minfree values, so the low level system task killer will take care of the apps running in the background for you (see the thread on tweaking). You can try with different settings and see what's better for you. Some apps drain your battery life even when you don't use them, while others don't and it's better to leave them in the memory than run them all over again every time. Do some tests and see what's best for you, if you have time for it.
10. Switch auto-syncing apps to lower values when possible (sometimes PUSH is better, sometimes worse for your battery life).
11. Keep it simple. Too many funky animations, floating wallpapers, lots of nice widgets will make your battery drain really fast.
12. Try different custom launchers, you can set more UI behaviour rules in these (see this apps thread).
13. Use a dark wallpaper and dark themes / night reading modes (see why).
PS JuiceDefender reported to having disabled deep sleep, so stay away if possible.
Hotmail app has been said to trigger wakelocks, while overriding system wifi sleep when screen is off, so keep that in mind if you want better battery life over constant e-mail syncing.
Hit [THANKS] if it helps.
First of all, thanks to d14b0ll0s for yet another great write up. I am one of those concerned with the battery life of the Infinity. Though some review says it got up to 9-9.5 hours with BALANCED mode I believe is the mistake. By using Power save mode, I think we can potentially get to that level but still hard.
My system is NOT rooted, but I have noticed significant change in my battery life so far with following:
1. Balanced Mode to Power Save mode.
This gets me like extra 2 hours or so. WIthout this change, 5-6 hours for my usage and with this it goes up to 7-8 hours screen time.
2. Under Wi-Fi Setting change Use wifi during sleep mode (mine is in Japanese so exact wording may be different) to never. Default setting was always. Prior to this change, I lost quite bit overnight unplugged; however, after the change it loses negligible amount.
Now rather than these, I am trying to play around with Juice Defender, which was recommended by d14b0ll0s in best application list he created. I have initially downloaded Juice Defender Free edition, and noticed may be minimal gain over #1 already instituted. But concept was great. So I ended up purchasing Ultimate edition, which allows us to control when to turn of WIFI per individual application based without Root i.e. while reading PDF I don't think I need WIFI connection.
https://play.google.com/store/search?q=juice+defender&c=apps.
I am still tweaking and playing with Juice Defender, but I am certain without change in #1,#2 (which are actually taken care by Juice Defender in its own way), I can gain same battery life and my hope/guess is I can get even more battery life.
So in conclusion, for those not rooted try Juice Defender (at least free version). I will let you all know how the ultimate version does in next couple days.
Thanks for this! ^^ Post 1 updated.
Have you noticed what power-saving mode changes apart from CPU (& GPU?) clock speed? Does it change auto-sync settings or unload some modules? I'm not using it, as it is too slow for me to render big pdfs consisting of scanned jpgs. But when I'm reading them with WiFi off on balanced, I normally get 9.9% drain per hour according to Battery Monitor Widget, which even with some other things that I do from time to time and some additional rendering when opening new files should give me about 9 hours on a single charge. Browsing over WiFi gives me about 7.
The Wi-Fi settings you mentioned are the same as WiFi power-saving settings on the bottom of ASUS setting list, but I've clarified that in post 1 now.
I'm happy JuiceDefender helped you, it's good to advertise it here. I'm adding the info about your post apart from the link to the list of apps.
Thanks
I would also add that it's good the deactivate unused apps/widgets (settings -> apps -> "select app" -> deactivate)
it's only possible for apps which cannot be uninstalled
Good point! ^ Added (-> p. 8).
Mine will be here this weekend.
Thanks d14b0ll0s
Look very useful! I'm about to try.
I think the standby time is awesome. Wifi off, power save mode enabled and left the tablet over night right after full charged battery w/o dock. After 10h still 100%.

#nice
The system measuring system isn't exact, and early on so are all the indicators, so don't rely on it too heavily. There may be a variance of 1-3% and a lot more in the usage indicators. Try different battery / apps widgets and compare the results.
Anyway, deep sleep is nice indeed. It normally drains about 0.2% (-0,5%) per hour, mine is now 98% after the night off the charger and responding to a few e-mails in bed
Thanks for the info, it's appreciated.
Antutu's Battery Saver worked great on my 101, I'm observing how it will regulate the power drain on my 700. Hopefully it will keep the back of the tab cool as well.
i think the problem is when you have wifi on!

this is good when you have wifi off. however, when you have the wifi on, it shows 80% wifi and 20% screen consumed by battery. you can stop network access by disabling wifi from Asus customized settings and also in wifi setting, you can keep wifi on during sleep to NEVER. this helps a lot..
Stock battery (usage) stats are not relevant, use other battery apps or widgets for that.
I've heard good things about AnTuTu's bat.sav., but also that it doesn't let you have more insight into what it's actually doing, so JuiceDefender seems a better option in that matter.
d14b0ll0s:
Do you know the specific voltage setting / configurations coming out of the usb line?
Is it 16V and how does it distinguish between 16V and 5V on the single USB cable.
For example does the voltage cable go on different lines for 16V and 5V for the TF700?
Or is it 16/5V dual switchable on the same power cable?
I'm asking this is because there's interest to charge the tablet by using alternative methods such as mobile battery with 16V setting.
If so, then does a DC to USB cable be suffice for the job? Or is the cable wired differently as proprietary ASUS?
Thanks!
Sorry, I wouldn't know that. There some ppl here that are doing some testing with the batteries and hardware, perhaps the_kreature or MartyHulskemper could know something. You should post it as a thread in Q&A too.

First of all, the charger gives 15V, not 16V. Avoid giving your tablet too much voltage as that can kill it...
Secondly, the included cable is a USB 3.0 cable and therefore has 5 extra pins (you can see them if you look straight into the USB plug). These extra pins are used to get 15V from the charger. I don't know exactly how that works, but I guess the tablet tells the charger it wants 15V over the power lines (same power lines as 5V) rather than the charger giving 15V over these extra pins (because that could be devastating to other USB 3.0 gadgets). This is why the tablet won't charge if you insert an old (USB 1.0 or 2.0) extension cable between the charger and the tablet.
Hey I'm running with wifi on during sleep and I seem to get great battery performance (2% loss over 11 hr standby). No build.pro tweaks so no deep asleep our anything like that. I'm wondering if anyone else has gotten similar performance?
I thought it was interesting because the results were the opposite on my tf300t, and my usage pattern hasn't changed much between the two devices.

Same here. Battery life on deep sleep with WLAN is great!
But I think the Infinity needs a lot of power while reading news, tapatalk, Reader HD..
Not more than 4 hours Screen On Time!
And that with balanced mode and 50% brightness.
Any problems with the fifth companion core?
PS: Is there an app which shows the activity of the different cores?

this is crazy, i got my tablet on monday, used it about 3-4 hours restoring all my apps and signing in to everything, and i havent used it much since but today, i'm still at 76%, havent plugged it in it or docked it. I also forgot to mention my dad played with it a bit also...prob about 1 hour
Hey guys so I know there are a few things that can improve battery life and some things that are supposed to help but may be a mith? Things as only draining battery to 10% and charging to 90% or something like this. What are tips that help? Also if you guys have changed your cpu settings that really improved the battery life let us know!
I drained my battery down to 0% after the second time I used it and it pushed my battery up from 3:30 to 5:30. I also use batterybar to see the stats and whatnot. Another thing you can do is go into power options in the Control Panel and change the plan settings > advance power settings. I usually change the Processor power management settings and the Intel Graphics Settings.

do you ever charge it to 100%
Does leaving it on the charger like when playing a game or something matter? Does it stop charging once it reaches 100
AFAIK, leaving it on the charger shouldn't matter. It's a smart charger. I always charge it to 100%, but never go lower than 10%. I try to recharge around 15%.
Best thing I've done is disable my bluetooth since I have no devices that use it.
Second is lower the brightness while on battery.
I'm getting around 5:30 of battery life doing things like browsing, email, news reading, and using Autodesk Sketchbook Design.
Disable automatic brightness. Change the screen timeout to the lowest value that works for you. Turn off BT. Turn off live tiles and notifications for apps you don't need to update on your main screen and lock screen. Run the troubleshooter for power and see if you can deal with what it changes.
Do voltage changes take effect immediately? I can't tell if adjusting the slider actually does annything and I'm trying to test how low I can go.

When you hit apply the voltage will be saved right away. I'm using System tuner in the pas but now using Android tuner but same principle.
I don't see an apply button anywhere, I've just been clicking "Save" and overwriting my last save each time. Is there an app that shows what voltage it's currently running at, like it shows the frequency it's running?
Trickster Mod
Trickster does the same thing...slightly easier to use.
If you want the voltages to persist after a reboot in ST make sure you go to boot settings and enable CPU settings as an init.d script.
After doing every possible combinations of ROMs and kernels and everything else under the son I have found the recipe for longer battery life and awesome performance all you need is the Deep Sleep Battery saver Greenify app and Go Power Master Hibernate all your apps then go to Go Power Master and make Greenify and Deep Sleep battery saver whitlisted apps schedule it the way you want Deep sleep battery saver that is as too what apps to sync so often or whatever and example I am used to running my phone dead four or five times a day I charged my phone once in two days when I used this combination so forget all those setting your processor to all these different speeds and profiles just use this and you will see the difference BIG difference unless your over clocked to 1.5 GHz or something even charging the phone and talking on it your battery barely drops this is one hell of a combination took a looooot of time to figure this or but works like a charm

If you have Deep Sleep problems, that Deep Sleep Battery really helps, but just turn it off (or freeze it) after waking your phone, since it still runs on background while you're using your phones, and consume some RAM, which we don't wanna...
Go Power Master, hmm... That "Optimization" thing just means "Clear Memory" (Background Memory). So if you have Task Managers who have that function, you can ditch GPM with your own Task Manager, less Apps installed
Greenify. The best so far. Cancels-out stupid background apps that persists (much better with the new version, GSF bye-bye! ). I only stay at my unstable 4.0 ROM for this baby (and also Xposed). If Greenify can be incorp'ed with GB firmwares, that would br awesome, which is not possible...
Additional tips:
• Lessen RAM usage (meaning close other running apps, foreground or background), to lessen CPU pressure.
• "Top-Off" your charging time. Do an extra 15-20 minute charge after 100% charging. If "fills up" the mV capacity , for the best full-battery experience
• If your phone can, Underclock/volt. Even less than a hundred mHz. It save some 15-30minute more juice on your phone. Just Overclock if needed, same as Setting the CPU clock to default.
• There are Rooted phones specializes on battery saving by:
*On Multi-Cores: Stop a core(s) to run. Really helps keep the CPU pressure off.
*Kernel Governors: Smartassv2, Hotplug, blah blah blah.. Search it...
• Limit / Lessen the usage of phone while charging. I don't know why, but I think its to, uhmm... prevent the battery pressure from charging-discharging, i guess!?
• Others are pretty basic. Backlights, GPS, Data, WiFi, Bluetooth... Yeah, no need to explain..
