Battery life

How is your A100 battery life?
I've heard its pretty bad from multiple people.

I've had mine now for a couple of days now and can report that battery life indeed is rather crappy. After an hour and a half or so of intensive use watching youtube, playing games, etc. the battery can go from 100% to 60%. Casual use reading books and with wifi off seems to drain the battery much more slowly.
Nevertheless, I like it much better than my iPad (which has a much better battery life) because it's pocketable (for large pockets) and I'll probably be mostly using it for an ebook reader. The form factor is perfect for this.
I would say if you're into heavy gaming / movies, and take lots of long flights then avoid this at all costs, otherwise it may not be that bad depending on your usage. For me it's not such a big deal.

Well multiple informed you wrong. Is it the best out there in the terms of battery life? No, but I get a full day out of it without a problem. I use it to surf the web, play music, a few games, tether to my phone via bluetooth for texting, etc...
If I used it nonstop I would guess that it lasts 6-7 hours with the screen on, longer when the screen is off playing music.
I also have a Nook Color and I would have to agree the battery is slightly less then the Nook but the device is much more powerful as well. The Nook's standby time is much better then the a100 but if it is used they are comparable with the Nook getting a slight edge.
A lot of people complain if they have to charge the device every night, I say so what. I also have to charge my phone every night. I have both chargers next to my night stand and when I go to sleep I am not using them so let them charge for the next day.
The WiFi and the GPS are the biggest drain during idle times I have my WiFi set to turn off with the screen. The GPS hunts for a lock all the time. I fixed it by replacing the GPS config file with one found on XDA that allows for a faster lock.
The only downfall I have with this device is the lack of a recovery or custom rom development. I hope that by the time ICS is released we have a upgrade path to install it.

+1 from me. Literally everything painter said, is what I find as well. 6 to 7 hours of constant use might be pushing it though. I'd guess it's more like 5 to 6. Maybe I just use the backlight set a bit higher.
And yes, the GPS on this thing KILLS the battery really really fast.
Painter, what's the link to the replacement config file?

Yeah, I also have the same feelings for the battery life. Sure, it could be better, but it will last me all day of on and off use. It might be a pain for traveling, but so far, it has served me well.
I don't have a problem with the GPS it only turns on for specific apps but it never just randomly tries to find my location.

I wish the battery was better, but it took my son over 5 straight hours to kill it playing games nonstop. I leave the gps toggled off. For regular use, it will run pretty much all day.

So is this good news or bad news to you? I'm just curious if this convinced you to buy the tablet, or that the A100 is not fir you.

Its not fit for me. My phone gets better life.

I think that this was the one. There are many gps fixes on XDA. Search for gps.conf for instructions. I was looking for a fix for my phone and put the file on my A100 also. fixed it right up.

Painter, could you upload your gps.conf or cut and paste the contents? I tried the one at the link and it didn't seem to help.

Here is the one that I am using.
1) download the attached file.
2) rename the file to gps.conf
3) put the file on your tablet using adb or root explorer
3a) adb method.
adb shell "mount -o remount rw /system"
adb push gps.conf /system/etc/
reboot the tablet​3b) use root explorer to copy the file to /system/etc and reboot the tablet.
4) make sure the clock on your tablet is correct. ( I use clocksysc from the market )
5) install GPS Status from the market.
6) start GPS status. ( the GPS antenna seems to work best if the tablet is held with the SD card slot up. ) It may take a while to get a lock the first time but after the first time the lock will be much faster after that.

Wrong forum. I delete my post.
Sorry

About battery life...
I have a 80G9 Turbo with HDD.
I recently removed the 256GB internal hard drive, and replaced it with a SSD.
I choose a Samsung 840pro (7mm) 128GB, because it has a very low consumption (256GB SSD was too expensive...)
A little difficult to do, and I was afraid to break my machine (and the warranty is lost!) , but now I successfully increased my battery life.
Before it was less than 6 hours (intensive), now i can work for 7 hours or more
(But no real speed increase...)

Juice Defender & ICS

Do they play nice together in the G-Nex sandbox ?

I remember RAM doubler for computers. This is a long long time ago, it came out in the end, they were just a scam. I don't like software that says it extends memory, battery etc, when it itself sits in memory making threads, taking up memory etc. I might be wrong but smoke n mirrors.

Every time anyone posts a question about JuiceDefender, you will get a bunch of hater replies but, yes, it works fine on the Galaxy Nexus.

Well .... the naysayers can say what they like. I run it on my Charge and I un-plugged the phone around 11a eastern yesterday @ 100% charge. I used the phone several time yesterday, took and placed calls, read some twitter and facebook, googled some things, it sat overnight on my end table and it was still at 58% charge here @ 7:30 the next morning.
That was un-heard of before I started running JD Ultimate..... Just Sayin .....

If you read how juice defender works, you will understand that it can and does work, but only noticeable improvements come from periods of none use of the phone, longer periods more savings
Works fine with my gnex, get good battery savings on work days, not so much on weekends, all comes down to usage

Umm ... yeah... wasn't THAT long ago. I was a field service engineer, repairing computers in the late '70's. This was before the advent of the desktop computer and pc, systems were the size of your refridgerator. A 10 MB hard drive platter was larger than a vinyl LP record and RAM was 'Static RAM' coils.
So .... I go back a few 24hrs with technology myself. And I am here to tell you JD works terrific on my Charge. As stated above, where you see the improvement is in the idle/sleep state. JD shuts almost everything down to minimize battery usage. Obviously, it isn't going to 'extend' your battery during moderate to heavy usage.

Works fine on my GNex , my only complaint and I dont know if its dealing with Verizons network . It sometimes takes a while for the 3G to kick back on after the phone is unlocked .

I used it all the time on my Bionic, but I've gotten better results without it on my nexus. Your mileage may vary, of course.

I have noticed under partial wakelocks the JD service is always leading the list on my Nexus. Not sure if I get better battery life with or without it (still playing).

Remember jd does wake the phone every 10mins or so to activate data to check for emails etc, that would be why its there

Cracks me up the people that slam apps that have never tried them or even read on them.
JuiceDefender works and as with many things your benefits will vary depending on your usage. On my old incredible JD showed 1.6x battery life which was also represented in the time it lasted. If your in a place with poor signal like a building all day for work it can make a big difference. It does have down falls if you depend on exchange email or etc as apps that require data can be delayed.
So far for me the Nexus appears to have much better battery life than the incredible so I'm going without it for now.

Thinking about getting it

I currently have the galaxy s2. Hows the battery life on the nitro? Cause I had the LG thrill and it sucked and so did the camera. How is that on the nitro?
Sent from my SAMSUNG-SGH-I777 using XDA App

Stock, the battery life of the Nitro isn't so great. About in the neighborhood of 8hrs with medium usage. If you don't mind rooting, debloating and tweaking than you can get better results.
The 8mp camera on the Nitro is decent to good. Sharpness, saturation and white balance are about on par with any other higher-end phone. The negative though is it can take up to 6 seconds from 1st shot before you can take the next shot...So this is NOT an action capable camera.

I wouldn't say 6 seconds, dat's a little steep, but definitely not instantaneous; ballpark i say is somewhere around 3 seconds shutter lag, but that might be due to the crappy 16GB class 2 SD Card that comes with most of the P930.

No lag on Class 4 sdcard, rooted, hard reset and debloated.

what does that cut the shutter lag to? have you tried a faster card than class 4?

I have a class 4 and it takes 2-3 seconds between pictures.

sounds like the class 4 takes a little more than a second off the process. i'm getting ~4 seconds shutter refresh on indoor well-lit snaps, maybe a bit quicker outdoors in full sun.
anyone tried a class 10? usually overkill for a p&s but maybe with this device........

Processing lag is about 2 seconds with class 4 but then I havent seen a phone that was faster. Is class 10 on the market? I saw class 6 but the reviews said that they write speed gain was barely noticable.

Btw this is my second day without recharging mid day so the baterry is not near as bad as evo 4g or any mobile on wimax.
Also for anyone that caress, the touchscreen is a bit different than on sg2 or skyrocket (a bit different response wise). I definitely noticed that I am making less mistakes while typing. It seems way more precise than anything before.

It's probably related to finger-to-finger difference. My typing on Nitro is way worse then on Atrix 4g, with keyboard buttons smaller then on Nitro.

My typing on my galaxy s2 sucks lol
Sent from my SAMSUNG-SGH-I777 using XDA App

The keyboard on this phone actually drives me nuts sometimes. When posting for example, it's incredibly slow to register my inputs. But, over texting it's almost too sensitive. I don't know why but it also registers the first letter twice sometimes. I guess I just have to get more used to it. Wish it can be iPhone keyboard smooth.

just fine
At first I was skeptical of this phone.
Now, it works just well. I can stream music for an easy 6 hrs. I can do the same task I've done on any other phone with pretty much the same battery usage. If I'm having a slow day at work and I know I'm using my phone heavy I will plug it in and use it. Or if i'm driving I will have in charging. it's exactly the same way I treated my iphone or other phones in the past.
The soft keyboard is a bit touch and it does lag pretty good at times..
The phone is fair. There is really nothing out there that my provider can offer (BELL)
It's got the HTC RAIDER (even worse battery life) and the Nexus (no expandable storage) - which was actually the deal breaker. I do not like being restricted to 16gb max. I like to know I can carry another one with me or have a 32gb. I like to carry movies and music..
I still wish there were more phones with FM tuner built in.. That would be perfect!
Just my 2 cents I guess.

I bought the sgs2 skyrocket, exchanged it for the nitro HD, and then returned the device 2 days later. The battery life, even with little use, is bad. I would seriously think long and hard about making the switch.

It doesn't matter to me which phone folks get but 2 days with this phone is simply not enough time to accurately gauge this battery. Hell, I don't think a week is enough
This phone needs a fair bit of set-up, including full drains/charges and bloat cleared out, etc. but after more than a month with this phone I can say the battery is performing entirely different than it did on day 2 and it is not an issue (other than my trying to make it one).
The fact of the matter boils down to this for me:
I wanted the screen and I wanted the LTE. Those features are part of what defines this phone and those 2 features are the top battery drains and would be on any phone.

I agree with what Scott mentioned regarding the battery. A little over a month and now the battery can last much much longer even with gaming and all. Somehow the phone adapts to your usage and becomes more efficient. Not much more, but better than when it was fresh out the box.

I'm glad to hear that your experience is similar, says a lot about this device.
Another thing about the battery, it charges fast IMO. I like to let mine go to full drain before charging up and I just did a full charge in 1 hour ~40 minutes and that reflects most charge times for me.
I don't have much experience charging other smart phones but that's a very acceptable time for me.

Yup, indeed this phone's battery charges really fast, fastest of course with chargers that give out higher amps. Using the stock charger (1.2 amps) I can fully charge the phone at about the same time u mention, sometimes even faster. Using blackberry chargers (0.8 amps), it takes a bit longer, but still fast. It's nice to see a phone charge that fast. The atrix took a long time to fully charge, and that's not from a full drain too.

Battert Usage - Former iPhone User Surprised - 4G LTE? PowerAMP Wakelock?

With these larger screens and powerful processors, I can't say I'm totally surprised at the lower battery life compared to all the iPhones. They have smaller screens and the O/S is more tightly controlled and optimized for the hardware to maximize battery life.
With that said, I must admit, I'm somewhat disappointed with the battery life on this S3. I've now had it for two weeks so after lots of tweaking, rooting, apps installs and configs, battery and task monitoring, etc, I've kind of settled into my normal usage pattern which is typically pretty easy on the phone as more than 50% of the time I'm working from my home office with the phone plugged into USB so it is rare I have to leave in the morning and go the whole day without having to eventually sit back down at my computer and plug the phone back in.
However on the weekends, with kids sports and such, I'm now seeing the limitations on battery life on this phone. I have it set to:
Auto Display Brightness
No updating of apps unless on WiFi
GPS and Wifi turned off when I leave the houose (automatically via Llama - I turn them on only when I need them)
Power Saver Mode, all options except CPU power saving checked. (Kind of bought the phone for fast CPU although I'm not a gamer - just a multitasker and web browser)
Auto Screen Tone Turned On
Most other specific apps that have option to not download data except wifi I have that option turned on (aside from Taptu news feeds - 2 hour updates and Alerts from ESPN ScoreCenter - get maybe a couple alerts every few hours)
Haptic feedback turned off
Here's where I was shocked. First time I did some serious browsing was in a movie theater where I got there early and had about 20 min to burn so I did constant web browsing over the LTE connection. Watched batter plummet about 15% in 15 min. Whoa!
So is this just "how it is" with this phone that heavy LTE data usage eats battery like no tomorrow?
Other thing I noticed, is Using GSam, I see a task usually being in the top 3 or 4 most of the time with around 15-20% of the App Battery Usage total. It's called "System (*wakelock*)" and when I look at properties it shows around 6-8 wakelocks and Included Packages is just one "PowerAMP Full Version Unlocker" Included Processes: *wakelock* and com.maxmpx.audioplayer. But this is when I'm not using PowerAMP. In fact it happens after phone has been rebooted and I have never launched PowerAMP once!
I did notice something similar on the HTC One X+ I tried then exchanged for the S3 where I found a task associated with beats audio was eating up CPU/Battery when no music app was open as if it was periodically scanning my large MP3 library of 2,600 songs. Maybe PowerAmp is doing something similar?
I've found I'm not the only one noticing this:
http://forum.powerampapp.com/index.php?/topic/2662-battery-drain/

Well, first off, i think the main reason why the iPhone gets better battery life isn't because of the smaller screen or iOS being "optimized for the hardware". It's probably more due to the fact that it doesn't really run much of anything in the background. Very few apps actually continue to run when you leave them. It's kind of a pseudo-multitasking environment.
As for the S3's battery life.... it could be PowerAmp causing it. I also don't see why you'd want to keep power saving on the CPU off. It doesn't really seem to have that much of an impact on performance that i've seen while generally using the phone for web browsing and such. And no matter what phone you're on, LTE will kill the battery in no time flat.

I think you should give some time to settle your battery first...even after flashing a new rom its take couple of days for the battery to settle down. The first day i used my phone, the battery doed in 4 hours...now after 4 months it lasts for 15-16 hrs of normal to heavy use.
LTE does eat lots of battery, whenever i go in LTE area i have to switch my data off to keep my phone alive. That's why people like to have the ability to switch between LTE and HSPA+. Search to find that mod.
You can never compare iPhone with S3. As the above poster said, there is no multitasking in iPhones. The screen is small and not as good as S3. SAMLOED screen takes lots of battery.

I totally agree with you. You have to give it time to settle in. You can also run a battery calibration to try and help as well. I have LTE here in Omaha and I usually get at least 15 hours before I need to charge my battery. I have a QCell battery and it works awesome.
I will live with the battery life so I can actually see the screen without having to squint my eyes. I used to have an iPhone as well but that was years ago now and Android will always be the best.

Don't get me wrong, as a "Power User" coming from the iOS Jailbreak world, hardware and customization-wise, I love this phone a lot more than I like my iPhone - but mostly it's the big screen that I'm enjoying. Have had a couple crashes in the first two weeks which never happened in iOS but no biggie.
So I suspect its primarily the LTE, but combined with large screen, true multitasking O/S, etc, obviously battery life is a challenge. I would slightly criticize Samsung for maybe being a little too obsessed with keeping the phone thin. I know you can buy the bigger batteries with a replacement cover but that looks like it really adds major thickness to phone. They should have went for a 2500-2700 mah battery and increased the thickness slightly IMHO.
But hey, at least the battery is removable. So I can spend little money and get a QCell, charge it and keep it in my car or on my desk and if I know I'm not going to be able to charge the phone all day, just pop the extra battery in my jacket pocket.
The LTE usage is a bit of a mystery to me. You would figure, with LTE, you can download files faster so you spend less time actually using the phone. But obviously it appears the energy consumption is trumping the increased efficiency in data transfer! Too bad.
Why the battery 'breaks in' over time is even more of a mystery. This latest battery technology should not have any sort of break-in or memory issues. But I'm no battery expert. But my gut says there's something else at play. I've seen many threads over past couple of years that discuss an issue relating to Android doing some sort of "media scan" after boot and/or periodically. Maybe the battery break-in is more about the databases the O/S is creating and updating in the background "settling down" more than anything to do with the characteristics of the physical battery changing?
One thing is for certain though, battery life IS a common issue for most higher-end Android smartphone users. Not a deal breaker in the least for me, but will be interesting to see how the phone "seasons" over time regarding battery. I used Titanium Backup to freeze Power Amp and downloaded N7 instead just to rule Power Amp out. I just took a 1.5 hour shopping trip. Didn't use LTE data. But spent about 45 minutes at the grocery store using their wifi to access all my coupons and shopping lists. Battery was 97% when I left house, 77% when I got home. Ouch. Well, that was probably more like a 2 hour round trip. Still 20% in 2 hours is not good especially considering I had 0 talk time and wasn't using LTE data.
The crazy thing is, Gsam says 12% screen, 86% apps. Under apps it says 23.6% Kernel, 19.3% Media, 19.3% N7 Player!!! And I didn't play any music!!!! This is leading me more and more to believe this all has something to do with having an extremely large music collection (2600 songs) on the phone and the phone is building a database and it just takes time. Pure guess.

Get his app disable autostart of the applications that are not needed. Also, get betterbatterystats to get a more detailed idea of whats going on with your phone.

how bad is your battery life? fwiw my wife's iPhone 5 gets horrendous battery life. makes the s3 look like a miser.
16 - 20 hours would be reasonable IMHO, or a average drain of 4-5% per hour. assuming you're actually using the thing... I never understood people who cripple the thing and never touch it in order to get max life.

You know when someone pushes away an iPhone groupy I'm pretty sympathetic but this post is just a noob rage idiotic post. I didn't even read through all your points but will just say you need to spend more time learning
-there is autobrightness on root (and non rooted) and in fact autobrightness doesn't necessarily save battery...as much utiltiy as having say a brightness notification in the app bar or something like lux that allows you to control brigntness by environment/app etc
-it says nothing of what you have running in the background, spam apps, wakelocks etc (bbs) The fact your apps and music is taking up more battery than say cell tower stanbdy and screen display is an obvious red flag
- says nothing of how you checked your connections and how reception is in your area
Another point is the iphone 4 and 5 are MUCH thicker than the galaxy s3...they hold relative to the backgroudn processes etc running, a much larger and thicker battery. The same physical thickness of the s3 battery you could buy a battery with nearly twice as much juice.
We dont' know how you optimized your phone for your uses or whether you cleaned up processes, apps etc, how cleanly you flashed. Go and learn then come back and cry

Wow.... you tell him to learn then come back and cry.... say it's a "noob rage idiotic post".... and yet:

-it says nothing of what you have running in the background, spam apps, wakelocks etc (bbs) The fact your apps and music is taking up more battery than say cell tower stanbdy and screen display is an obvious red flag
- says nothing of how you checked your connections and how reception is in your area
Another point is the iphone 4 and 5 are MUCH thicker than the galaxy s3...they hold relative to the backgroudn processes etc running, a much larger and thicker battery. The same physical thickness of the s3 battery you could buy a battery with nearly twice as much juice.
We dont' know how you optimized your phone for your uses or whether you cleaned up processes, apps etc, how cleanly you flashed. Go and learn then come back and cry

Well here's an update. As I mentioned, I froze PowerAmp and installed N7 instead. I could have swore I reset the GSAM battery monitor, AFTER N7 scanned all my media files. Yet once again, like PowerAmp (via System *wakelock*) N7 was third highest battery eater over 2 hours of "normal" usage WITHOUT LTE Data Use, only Wifi and NO TALK TIME and WITHOUT USING N7!
So I dumped N7 and installed Player Pro. Just went out again for 2 hours to my son's basketball practice. Spent the 1.5 hour practice reading e-mail and doing some web surfing ALL ON LTE! Battery went down like no more than 10% !! At the beginning of the practice I played a song in Player Pro for a few seconds then backed out of the app. Checked GSAM 2 hours later, no significant PlayerPro battery usage!
It is more and more looking like something is going on with PowerAmp and N7 regarding cataloging of large music collections. So I'll stick with Player Pro and see how things go over the next few days.
Thanks to those with the constructive criticism. This has been one of the pluses of moving to Android. There's a lot larger population of "Power Users" than on iPhone that are willing to help someone relatively new to the platform.

yea... that's the one thing i had a feeling it might have been doing, but wasn't exactly sure as i've never really been that media-crazy with my phones. Good to see that you found the issue, though.

Why the battery 'breaks in' over time is even more of a mystery. This latest battery technology should not have any sort of break-in or memory issues. But I'm no battery expert. But my gut says there's something else at play.

Yeah, "battery break-in" is a bit of a misnomer. What's actually happening is that the stats the OS keeps on the battery capacity and usage are being rebuilt. It takes a few charge cycles for your system to "learn" what it needs to accurately show you remaining capacity, etc.

Good move! I use PlayerPro and I love it. It's one of my few "must haves", not least of which is its ability to sync ratings back to iTunes with iSyncr. None of the other major players have this. This is important for me as I'm also an iOS refugee and I still have all my music in iTunes.

power user here too coming from iphone 3g, 3gs, 4 to samsung skyrocket, note, nexus to the current at&t sgs3. all have been jailbroken and rooted for "customization" purposes and the first thing i noticed going to the android phones was how poor the battery life was when compared to any iOS device; even when the devices were stock. I can deal with it because of how much customization i can do with android that i can't do on iOS so for that reason alone i stick with android. and also nothing apple has done has impressed me with their iPhone series yet. might pick up an iPad mini retina one day :laugh:
anyways, back to your battery issue. have you tried going to stock rom or formatting just to make sure its not a hardware issue? i know for mine, one time my data partition that had my music had some corrupt file that had the media scanner always running and killing my battery. i had tried everything and there was no way that in 8 hrs i'd have < 30% left with no usage. i finally deleted and formatted everything, went to pure stock with no files except for my contacts and no email sync. then i got 15 to 20 hours... that's usual for the sgs3, a tad less than my old iphone 4. that told me my battery wasn't bad.
i ended up keeping an eye on wakelocks and re-installing all my apps and putting all my music back on and my battery issue dissapeared and i'm happy. still have poweramp installed, but moved to using google music for cloud and local music. what made me really happy was going to a hyperion battery and the slimmer extended sedio case for 2 to 3 days of battery life on this sucker for a decent price. :good: still have the stock batter for backup too!

I'm not on a Custom ROM. Just rooted.
I installed Better Battery Stats to see how it worked. Don't like it as much as GSAM. Seems you can get a bit lower-level process info upfront, but the graphing is barely readable and it doesn't show percent usage of battery for each process. Just number of s(econds) and blue and red line? Maybe I'm missing a setting? I think BBS may be popular as maybe it existed before GSAM (formerly Badass Battery Monitor I think) or maybe there is just something about BBS that I haven't realized yet is a major advantage over GSAM? They both do the job. Sorry for going off on a tangent.
The process hogging the battery the most now is Google Maps and I know from searching and reading this is VERY common. It can be related to ANY app wanting to poll your location. I'm not yet sure though if the usage is excessive. Looks like not. I turned off all of the Location settings in Maps (but left "Location and Google search" in main Location Setting ON as I read that really defeats a lot of functionality. Google Now wasn't happy I turned of Location History (in Maps) but I still get the current commute times and local weather on my Google Now so I have yet to discover any big disadvantage of turning off most (not all) of the Location settings in Maps if you don't want to share your location or see your location history.
Apparently Google Now and potentially other apps like Facebook, etc. want to use Google Maps to poll where you are. One user said turning off History helped on the battery - makes sense as now Google Now isn't constantly trying to see where you are even if the phone is just sitting on your nightstand! I hate that big brother feeling so anytime an app has an option to turn location awareness off, I usually use it. When I go to use Maps I just turn the GPS on. But I still need to learn what I'm missing out on, when turning off some of these settings. Now I'd like to figure out how to get GPS to turn on automatically any time Maps is manually launched and then turned off automatically anytime maps is closed! That would be nice. Surprised that function isn't built-in to Android as opposed to just prompting you to take you to settings. Guess I may have to break down and learn how to code in Tasker instead of using Llama for my automation needs.
I've left the phone unplugged for what, 8 hours now. Very light usage today. I'm at 80%. BBS is showing 3.5%/hour. That's 28 hours. But like I said, no talk time on the phone today, a half dozen texts, no web browsing and maybe 30 min of total app usage so I would expect 3.5%/hour.
Bottom line is it looks like I don't have any major issues like I had on the stupid HTC One X+ that was getting hot. Seems like the media player switch is what did the trick. I'm just curious why apps as popular as N7 and PowerAmp would be any different. It could have been just timing in that I switch to Pro Player about the time the O/S was done doing it cataloging of the media or whatever it does. I'm sure 2,600 high bitrate songs (14GB) of songs on the sdcard is pretty above average for your typical Android User. Wish there was more in-depth technical documentation on some of these processes though published by Google for us Power Users to read if so desired. Guess that's why we have XDA Forum.
-- add --
Duh, just saw the first condition in Llama is "Active Application" the problem is, I only want the GPS to turn on when I manually launch the app myself. I hope an app trying to use Maps in the background doesn't trigger the GPS on. Guess I'll find out.
-- add --
I forgot why this isn't possible. Google doesn't want to allow ANY apps to turn GPS on/off automatically due to privacy issues. Is there a setting to let the user decide this? Make me feel like they're treating me like an idiot!

Jumped to the Maxx HD

Well after much deliberation I decided to make the jump to the Maxx HD. The M, while awesome, just can't get me through a full day of work. I really wanted a phone that I could push all my email, run everything and still have battery when I go to bed. My friend has the Maxx HD and gets just that...
The M has been relegated to my Mom, as the wife decided she wanted the iPhone 5...

Later buddy

Wow this is one impressive result mate.
I was thinking between MAXX HD and M (like the battery in MAXX HD and screen size in M) and this image convinced me to buy M.

You're not going to see battery life like that unless you hardly use your phone.

True.... I averaged 3-3.5 hours of screen time and was lucky to get more than 12 hours on the M.
This is my first full day with the Maxx HD

I've been impressed with my M thus far.
Sent from my XT907 using xda app-developers app

I could see making the jump (or just going straight there) if battery life were poor but I guess for me coming from HTC phones where the largest battery I ever had was 1620mAh I feel like battery life of the M is fantastic! The small size and form factor is far more important to me than HDMI out, internal storage, 720p screen or huge battery. Perhaps if they had made the Maxx HD more powerful/faster I'd be more intrigued but as is its just a bigger uglier version with huge battery.

Of course your milage may vary and I agree with your assessment of the M...
Coming from the Thunderbolt the M was fantastic and the battery life was awesome in comparison. But I found if I used heavy during the day and didn't top it off and I had to go out after work I was pushing the limits. The form factor of the M was great also, same size screen as the TB but better, lighter, and thinner.
The Maxx HD, while bigger and uglier than the M is the beast I was looking for. I was tired of having to carry extra batteries with the TB and having to be conscious of the battery on the M with heavy use. I was really tired of having to disable features to get a full day of use.
I plugged the Maxx HD in last night after 16 hours at 39% with almost 5.5 hours of screen time. On 4G all the time, no wifi use, pushing 2 email accounts, streaming some music, reading RSS feeds, some YouTube, and some web browsing... I can deal with the big and ugly.

Seriously if you're on your phone non stop then yes the battery will die. But the m has the best battery life I've seen in two years (as far as phones I've owned). I don't use smart actions, I have WiFi on at home, I have GPS on all day, auto brightness, and I get a day easy. If you don't get at least 15h then you're using your phone excessively.

I use my phone for work and average several hundred emails a day and i am on call 24/7/365 so yeah I am on my phone a LOT... I don't consider it excessive the way I use it. I am not playing Angry Birds or watching Netflix for hours at a time, but then usage I describe is what I do every day...
If you are happy with the M great, I am just adding perspective for heavy users that need a device to go the distance with out having to cut corners...

You use your phone too much
Then there is no alternative for you. MAXX HD is just perfect choice.
I use not more than 2.5h of display on my phone so I guess RAZR M should fulfill my daily needs.
I hate Motorola because of its "we are not unlocking our bootloaders" policy, but they make awesome phones.
Sent from my MB525 using xda app-developers app

For me, the Razr M is a good compromise between size and battery life.
I was tempted to get the Maxx because it was relatively thin, but still its too wide for me.
Although the M's battery life isn't as good, its still better than most phones out there. I get 20 hours on the M easily. That's more than enough for me.

Because receiving hundreds of emails a day on your phone and expecting a full days battery is realistic.
Sent from my XT907 using xda premium

I was ready to ditch my M and go with the Maxx. I use about two hours of phone time a day, some email, text, browsing and I'm not near a charger for about 10 hours a day. My battery wouldn't get me through the day. I bought a morphie from Verizon.
After spending a lot of time monitoring the battery and searching the net for solutions, finally found my problem. I disabled google latitude updating my location and my battery life nearly doubled. With the phone just sitting off charger and very light usage, I'm seeing about 1.2%/hour. I don't even worry about my battery during the day anymore. On a typical day I'm well above 20% by the end of the day, usually in the 30-40% range as I recall. With two hours of phone time plus I'm in and out of signal areas and weak signals, I'm very happy with the phone's battery.

Your response doesn't make any sense, but I'm assuming you are trying to say it is UN-realistic... to which I will offer the following response:
No, it's because you have the audacity to tell someone else how much is too much.
Aside from that, you apparently have no understanding of what the RAZR MAXX HD is capable of in regards to battery life. Here is an excerpt from a previous post I made, after giving up on the HTC DNA:
"3) Lack of replaceable battery in the HTC DNA.
Now, before you bash me for getting the RAZR MAXX HD (which also doesn't have a removable battery), allow me to share the following:
With the RAZR MAXX HD, I now have a phone that actually gets me through an honest day without needing to be recharged. Heck, just this past weekend, I left my hotel in Orlando at 9AM and headed out for breakfast and then to the airport. At breakfast, I listened to music, surfed the web, and used Facebook using mobile data. Played some games on my phone during the 40 minute bus ride to the airport. Flight was delayed til 4PM while I was at the airport, and I watched some videos and streamed a full length movie on Netflix while waiting. During the flight, I kept the phone active because I was really curious how far the GPS could pick me up using the app GPS Status - - this was pretty cool to see that the plane leaves the ground at around 155 mph and it tracked me all the way to 530 mph at 29,000 feet and never lost the signal until I put it into airplane mode, at which time I watched another full length movie with the screen @ 100% brightness. Finished it off listening to some tunes on a set of around the ear Bose headphones until the plane landed. Made a few phone calls on my 45 minute ride from the airport to home, and upon my arrival in my driveway at around 8PM, I still had 40% battery left. NOW THAT IS A PHONE THAT CAN JUSTIFY NOT NEEDING A REMOVABLE BATTERY!! "
