that looks decent to me. your biggest app drainers was Facebook and you web browsing. you still got over 7hrs. of use. then you have 11% left in battery. easily an hour or so left. so 8 hrs. of use. you probably could've gotten even better but for one, we don't know what you had your screen brightness set at. then two, we don't know what powermode you had it in. seems good but could be better if you wanted it to. by changing a few variables that contribute to battery loss.

Blame on Drive and Facebook

Last night I disabled sync for Google Drive and killed Facebook. My Prime was 99% charged.... this morning the Prime shown 98%! I blame Google Drive for trying to always sync (If you open the app it never stopped syncing, maybe the current version always try to sync even when the prime is on sleep mode).

Then on my battery stats I noticed that Facebook was on top along with WIFI, so before going to bed I completely killed Facebook.

My problem started last week just when Facebook released an update and Google docs was updated to Google Drive.

Try this... this could be your problem too.
[Asus  Eee Pad Transformer Prime] mdemons12:
Sorry, brightness is usually between 0-30%, really mostly 0 as i used it most of the time at night. I run it in power saving mode as well. But i dont know if this is because its a new battery but i find certain percentages on the battery dial last a lot longer. 100-90% lasts over and hour, from there on its an hour to quite a bit less than an hour. It really varies.
[Asus  Eee Pad Transformer Prime] demandarin:
now that i know more details my answer changes up some. if you running on power savings mode and only have brightness between 0-30%, your battery life should be better. at least an extra hour or 2 usage.

you did run facebook over 2 hrs. so may be the reason why. it was your biggest or one of the biggest battery drainers from what you showed. keep checking your battery stats to see if anything else pops up. can you post the other screen where it shows wakelocks n things like that?
[Asus  Eee Pad Transformer Prime] mdemons12:
I amstill pretty new to all this android stuff so could you pleasempoint me to where i can find the wakelocks?
[Asus  Eee Pad Transformer Prime] demandarin:
when you open better battery stats, you should see it. especially if its on processes and since charged. mines not showing yet because I had my tab docked.
[Asus  Eee Pad Transformer Prime] mdemons12:
Yep, found wakelocks on the list of processes and stuff. I will upload a **** after some more use. Anyone know how to upload a **** from the tab. When i go to choose file i can't do anything, i have to do it by computer
[Asus  Eee Pad Transformer Prime] demandarin:
opera mobile browser allows you to upload stuff just like on a computer. one of the many reasons I love using opera mobile. its the closest to a true desktop browser. once you click choose file, a mini file explorer will pop up and you can choose whatever you want to upload from there.
[Asus  Eee Pad Transformer Prime] mdemons12:
One last thing, in the battery stats, what is the difference between the tab been awake and screen on?
[Asus  Eee Pad Transformer Prime] clouds5:
Screen on means, screen is on :)

Awake means the tablets screen is turned off but the hardware is being used, for stuff like syncing email or checking a sensor. For example when you're listening to music with the screen off this should show up as "awake" as well.

If the tablet is awake for long periods of time without you knowing what its doing there is probably a "wake lock" going on. Meaning an app/process keeps the tablet awake while its just lying there doing nothing.

Obviously awake uses more battery than "deep sleep".
[Asus  Eee Pad Transformer Prime] mdemons12:
How do i get it to deep sleep for night or is the best option to just turn it off
[Asus  Eee Pad Transformer Prime] buxtahuda:
That's what we're looking for actually. Your tablet should enter Deep Sleep any time the screen is off and you're not trying to run anything. But something is keeping it from doing so: a rogue app or bad update configuration. Keep watching your stats and appropriately reconfigure or uninstall the culprits, or get Tasker and set up some profiles to counteract them. Can always limit the number of background processes as well. You are now on your way to learning to truly control your Android devices, now we need to get into some under-clocking and under-volting and your battery can last a week or more.
[Asus  Eee Pad Transformer Prime] HarnessTech:
Please don't upload a ****.
[Asus  Eee Pad Transformer Prime] mdemons12:
Haha, still getting used to the keyboard and that one got past me i guess

---------- Post added at 10:44 AM ---------- Previous post was at 10:39 AM ----------

Well i do quite frequently just kill tasks. At a time i would say i would have a max of 2-3 recent apps running and maybe 5 in the task manager i try and kill off regularly. Now knowing there is a difference between screen on and awake it seems i am getting much less battery life than i expected. 12 hours on the spec sheet and i would expect a bit less cos i am actually doing something but 8-9 hours just seems so little. I hope Asus can get a fix. Last night it didn't change percentage wise but basically as soon as i turned it on it dropped 2%. Thats what i hate about the battery gauge, you think its going great but then all of a sudden you lose 2%.
[Asus  Eee Pad Transformer Prime] mdemons12:
Here are my latest results for this time round I think I used it more heavily and had a bit of riptide in their. Also worth noting riptide was in 3D.
[Asus  Eee Pad Transformer Prime] casey225:
Battery life sux after .21, I haven't exactly put a timer on it, but, it seems like I lose about 1% per minute. Horrible! No improvement in wifi reception. I am in the room beside my router and get 1-2 bars. CPU spy says it goes into deep sleep, but, if I don't turn it off at night it has like 20% charge left. If docked, the dock will frequently be drained and the tablet will have 80 - 90% charge. I try to remember to turn it off at night now.
[Asus  Eee Pad Transformer Prime] stdlyman3k:
Hey sorry but what is the name of the app you guys are all using ? Battery status? I can't find it. A link would be amazing
[Asus  Eee Pad Transformer Prime] mdemons12:
I use battery monitor widget

Really hoping i can get some better battery life out of some new firmware. What makes me think i won't is that i appear to be getting better battery life than the people that are getting the really bad battery life and i didn't give the prime an 8 hour charge as i probably should have. Everything is off when it sleeps like wi fi and all apps, some it would hopefully be a more system based kind of problem.
[Asus  Eee Pad Transformer Prime] mdemons12:
Here are the estimates i am getting after 2 weeks of having the orime and .21
[Asus  Eee Pad Transformer Prime] demandarin:
Better Battery Stats is the name. it's here in xda. just use search to find it.
[Asus  Eee Pad Transformer Prime] jupppo:
My problem is actually not deep sleep. My prime enters deep sleep correctly. In addition I am using Auto Airplane Mode (App) to switch of WiFi right away when screen is off. As stated earlier my WiFi is draining the power in connection to certain router types. It didn't do this on the prior firmware version.
[Asus  Eee Pad Transformer Prime] fordwolden:
Tired of waiting! Huge Improvements!

Yesterday, after waiting for a new firmware er since the .21 was released, I finally had enough and downgraded to .15 and blocked the OTA updates. On the .21 my battery was draining so fast I almost hesitated to use it, now that I am back to .15 the batterlife is back to it's normal fantastic self.

I wish I had screenshots to show you guys the brutal change, but I don't. What I can tell you is that on .21 I had "auto airplane mode" that shut of wifi when the screen was off, still I only got 4 hours of "Deep sleep" during a 48 hour discharge with 4 overs of use and "screen on". Now, on .15, whenever the screen is off I get "deep sleep". Last 48 hours I had 44 hours deep sleep and 4 hours use and "screen on" and of course almost no battery drain at all. It will last a week now with my current use.

Thought this thread could use a sunshine story. It's a easy process that you find

described all over this forum, and it doesn't void warranty.
[Asus  Eee Pad Transformer Prime] sledgie:
I have to agree. I don't post a lot around here but I do read a lot. What I will say is this: If I want to turn my prime into a computer that doesn't check my email often, doesn't sync, doesn't have normal brightness, under clock it, turn down the contrast ratio (battery saver mode), uncheck options that allow me to look for stores close to me (Lowe's/Google location search), cut off my display after 30 seconds, disable haptic feedback, and turn flash off when browsing: i mean, what the hell is the point of this computer? Are you telling me that magically from the .11, .13, .15 update to .21 that I have to do all these things just to "conserve" battery life?

Of course not. It's obvious Asus changed something to increase wifi strength in the latest (.21) update. Prior to this update I *still* had ****ty wifi, but I had battery on my tab at least 6 hours, and with the dock I could make it 7am-7pm easily with 15-25% left. I'm not changing my syncing, or doing anything you said to make my Tablet inoperable to my standards (which aren't very high actually and they shouldn't be when using an Asus tablet). I mean, the fact of the matter is, prior to .21 we didnt have deep sleep issues. I could close my tablet at night and wake up 4-6 hours later with 8%-15% reduction, MAX. Not 50%-60% percent.

Btw, I might add, i completely reset my tablet. Wiped it completely. I've got weather updating every 6 hours, and gmail syncing when mail comes in. Big fricking deal. If my phone, which has a 1850 battery, can last 8 hours with dropping 15% overnight doing the same things my prime can dropping 60%, theres obviously a wifi issue going on, and thats in wifi mode with the phone on.

I think its crazy Demandarin that you can't "believe" that people's tablet battery is dropping so much overnight when they are now, and weren't 3 months ago. There is a sleep issue, whether it going into deep sleep and can't be awakened by opening the lid (or pressing the button) or whatever, but it didnt' happen (to my knowledge) prior to .21.

FWIW, I get better battery life at 50% brightness browsing the internet, with all the checks and syncs I'm doing, then letting it sleep at night. There's obviously an issue, which I hope Asus/Gary Key acknowledge in the next update (hello wifi direct and no you don't work like you should)
[Asus  Eee Pad Transformer Prime] demandarin:
you set your tab how you want. the "believe " thing was a figure of speech. obviously wifi issues were the biggest complaint. so they likely increased its strength to address the issue. I dont have deep sleep issues. my tab is rooted and overclocked and im on latest firmware and i get good battery life. Have i noticed battery drains a little bit more faster, IMO, yes. But nothing for me to gripe over. I use my prime extensively everyday for work and it lasts long during constant usage.

Those were only tips to save battery life in the meantime. Even before update, if you do some of those tips battery life would increase. this isnt nothing new. this goes for phones and tablets. people want to have everything syncing every 30 secs. and brightness on max and wonder why battery life sux. I don't need my email syncing every 5 mins. I don't need weather updates every few seconds. I don't need Facebook constantly syncing and running in the background. I dont need brightness indoors at 50%. i have good vision so a lower setting does fine for me. There are times when i cut it up but most of the time its not needed. Now if you dont have the best of vision , then constantly needing a higher brightness setting is understandable. People have different needs. i have the dock also and it awakens everytime i open the lid up. so obviously this doesn't affect everyone.

If you want the best battery life like you describe doing everything you want, just downgrade then like the previous poster said he did. I'm not going to downgrade because features and other tweaks are lost doing so. We already know about wifi direct and they addressing that also.
[Asus  Eee Pad Transformer Prime] fordwolden:
I purpously didn't speculate over reasons for faults here! If somethings broke, I fix it. The fact of the matter is that I used my tablet identically on to different firmwares, on one of them batterylife sucked on the other it was great. I never

had any other issues with my Prime, AT ALL. Wifi is great on both firmwares.

The conclution kind of writes it selves, the .21 firmware is bad, for batterylife.

Real bad. Maybe you can tweek and adjust the .21 to get close to the .15, but that is not the point. You shouldn't have to.

Enough babble here comes the .24, I have great faith in this one! :D
[Asus  Eee Pad Transformer Prime] chillaxx:
I have done some research into my battery drain. With dock attached (full batt)dock was empty next morning. So the dock was empty in just 8 hours, and the tablet was at 75%. I then installed BetterBatteryStats to see where the problem was. The app said that WIFI was the culprit. I then turned off WIFI and...........no change. It still drained the battery like mad.

After this I installed Badass Battery Monitor(BBM) to check on what apps cause the most battery drain. There was just one app that had a huge drain: Google+. I then changed the auto sync settings to off and uninstalled all updates. This reverted the app back to factory default. And to what result............. No more battery drain.

Anyone else have the same problems with Google+ ?????
[Asus  Eee Pad Transformer Prime] Trekest:
Interesting find.

I don't ever use Google+, uninstalled the update and disabled it. Let's see if it helps.

Edit: Roughly 90 minutes later, with it idling with WIFI on, dropped only 1%. Usually it would drop 2-5...
[Asus  Eee Pad Transformer Prime] 131313:
I certainly have noticed that turning wifi off didn't help the bat issue. Made me really wonder

I'll give your fiindings a try and report back.

Update:

well since I am not using google+ the issue with battery drain is still the same. The wifi still sucks almost as much as the screen. That sucks really.
[Asus  Eee Pad Transformer Prime] chillaxx:
Hope it helps. I must say that just a few days ago I updated a lot of apps. I'm not to quick with updating. Had about 53 updates(I have a lot of apps). Maybe that's contributing to this problem also?
[Asus  Eee Pad Transformer Prime] haberbe:
i uninstalled updates and disabled google + too.... it seems like my battery use on wifi is down pretty significantly. hopefully this fixes it. battery is all i care about
[Asus  Eee Pad Transformer Prime] jupppo:
Hi there, thanks for sharing your finding, but disabling google+ does nothing for me. WiFi is still a big sucker....
[Asus  Eee Pad Transformer Prime] chillaxx:
Just to be sure. Did you do the following?:

Install Badass Battery Monitor and check what app is biggest drain(and it says Google+ is biggest drain)?

In google+ app uncheck automatic upload in settings

In Transformer prime settings/apps/all applications/Goolge+ Uninstall al updates(reverting app back to factory default)

Restart your Prime

Check Badass Battery Monitor(or similar app that let's you see what app is biggest batt drainer) to verify that Google+ is or is not still the culprit?
[Asus  Eee Pad Transformer Prime] chillaxx:
Any new findings on Google+ battery drain or did we all throw away our prime's after reading the above post?
[Asus  Eee Pad Transformer Prime] haberbe:
i did the google + trick above. i uninstalled all updates, reverted back to the factory settings, and then went the extra step of disabling the app in settings.

i used my prime all day today while i was studying for the bar. wifi on the whole time. battery life was awesome. started at 8, and at 3:30, the prime was at 84% and the dock was at 44%! before this trick, it would have been way less.

Also did notice, however, that my gmail was not synching right (but my corporate email was). maybe disabling google + did something. any thoughts? i will try re-enabling google + tomorrow to see what happens to battery life and if my gmail will synch again.
[Asus  Eee Pad Transformer Prime] steinarlundemo:
Did the trick for me!
[Asus  Eee Pad Transformer Prime] jupppo:
Hi there,

I did not check BBM before I disabled google+ and restarted. But it's installed now. WiFi still sucks 50+%.

Hi,

I have a galaxy 3 i5801 which is one year old.

It freezes occasionally:( and i have to restart the phone by removing the battery.

I am also using the 3g an wifi , when i am using in 3g or wifi. the battery is draining very fast less than 10 minutes even after full charge, and the phone gets switched off.

When i switch on the phone it will again gets switched off before i switch off the 3g or wifi :eek: showing the battery in very low(RED status) .

when i am charging after this it gets full charge in less than half hour.

I have tried different roms.

now i have stock rom(froyo.xxjpm)

Please help me
[Samsung Galaxy Nexus] BlindWolf8:
Hello all,

I've been poking and prodding my new USA GSM Galaxy Nexus all day and I noticed something: the screen seems to have a dynamic contrast function, similar to that of new TVs. I would like to turn this function off, although I don't see anything in the stock ROM to do this.

NOTE: I AM NOT TALKING ABOUT "AUTOMATIC BRIGHTNESS".

I want to see if anyone else can reproduce this or if it's just me.

Turn off "Automatic brightness"

Set your phone to 100% brightness.

Hold your Galaxy Nexus in portrait mode.

Go to this page in your browser on your Galaxy Nexus:

http://www.samsung.com/us/

(make sure to request the desktop site and not the mobile site in your browser of choice)

Scroll down to the bottom of the page and zoom into the black section with all the links. Zoom in as far as you can. If you're using Chrome, the words "Who We Are" should go across the length of your screen.

Scroll your screen so the words "Who We Are" is at the top of the screen and no white background is present at the top of the screen. The lettering should be pure white. Remember where they are.

Slowly scroll the page up by swiping your finger down the screen so that you gradually see more of the white background and less of the black background until the black background completely disappears off the bottom of the screen.

Swipe back up so that the words "Who We Are" are in the same vertical position they were in Step 6.

Repeat steps 6-8 multiple times at a faster rate. As you keep scrolling, watch the brightness of the screen and/or the whiteness of the words "Who We Are". When you first start to see white, the white will be white, but when more white starts to take over the screen, the phone switches to a less-intense white. (I'm assuming to save battery)

Is anyone else experiencing this?
[Samsung Galaxy Nexus] amdfanTO:
download supercurio's voodoo mod sequel, the displayexpert beta in the voodomods forum. there is an option to turn off the dynamic brightness limiter. works perfectly! ;)
[Samsung Galaxy Nexus] RogerPodacter:
This comes up once in a while, and many people say they see this issue. But I just can't see it! The sgs2 has the option to turn this off, but nexus doesn't.

Is this available in the kernel code to view and tweak,or is it closed?
[Samsung Galaxy Nexus] BlindWolf8:
Are you considering adding this into AOSP and letting Google know, or just tweaking/adding to other custom ROMs? Or just curious? :p
[Samsung Galaxy Nexus] RogerPodacter:
I'm not really a dev in any sense, but would like to see if this function is in the kernel and not hidden. If its not hidden then I'd imagine someone would have added an on/off option by now. So I'm not the person to handle this. My ability is at most compiling my own kernel with a little code change, at most, unfortunately.
[Samsung Galaxy Nexus] @rbiter:
Yeah. There is some kind of brightness limiter like plasmas have it too to meet energy star standards. Its a lot less noticeable on a phone screen and probably helps with power management. It can be a bummer on plasma watching hockey or movies like ice age. I would gather there is a way to tweak it. On plasma, no go.

teach a man to fish, you feed him for life. teach a man to fastboot, and you create competency. and less threads on xda.
[Samsung Galaxy Nexus] BlindWolf8:
Hmmm? I have an LG plasma TV and I can turn off all the dynamic stuff fine. It's in an Advanced menu on my TV.
[Samsung Galaxy Nexus] @rbiter:
all plasmas can turn off dynamic whatever. i am referring to what is called auto brightness limiter aka ABL. i know samsung and panasonic utilize it in their plasmas. no way to tweak it. there is something similar with samsung phones with amoled. bright images get toned down because all the white/brightness suck a lot of juice. i don't know if it can be tweaked on phones, but i think it can somehow.

To disable auto brightness limiter at boot:

That's great new for everyone. I'm just curious what was the break though that helped? Samsung released more source code? Inside leak of a in house ICS build?

ICS Passion started us off. Neobuddy used the source from Nexus S (ithink) and built a ALPHA>BETA>STABLE ROM, after which more ROMS started showing up but they were pretty much Passion. Then CM9 showed up. AOKP showed up. Now we actually have a diversity of ROMS to choose rom.

This phone is great, thanks devs.
