[Q] Weak Battery - Asus Transformer TF700

Hello,
I'm new here and have a quest about my new tablet
I bought the Transformer Pad Infinit a few days ago and I think that I could use the battery for 9 hours more or less.
But my battery is extremely weak, I just use this 3 or 4 hours with the GPS off and bluetooth off too. The wi-fi is just on in the half of this time, and waht I do in this time is play some games and use the internet. I use the "Energy Economy" mode all this time and the light of the screen is in 20%.
I guess my battery is more weak than others... What can I do to "fix" it?
I would to say "thanks" for everyone, and I'm sorry by my english, I don't know english so well

The battery in your Infinity may be not charging to 100%.
I don't get 9 hours with moderate use...I see around 6 hours.
My wifi and GPS are always on and the screen is about 30%.
The batteries aren't supposed to have "memory" meaning: they should be able to be charged over and over from any discharge level back to a full charge.
There also might be something running in the background that is taking down your battery charge.
Have you browsed the battery saving tips in the stickies here in the TF700T forums?
Is your Infinity the LTE version by any chance?

First: Thanks
I search in the internet and I found that the Li-Ion batteries have to charge arround 30%~50%. I do it much times.
I was using a animed wallpapers and I change it by a normal wallpapers. I guess this make some efecty
I search here in the forum too, things about the battery saving, I found somethings that can be helpful, but no "so beautiful"
I don't have the LTE version, I guess nobody have it, Asus is so stupid when we talk about "3G/4G"
I don't know why, but mysteriously, the tablet use about 600mb of RAM and also nothing is running, just the things of the systen.
I guess it's strange, maybe that interfere in the battery life no? But how can I "fix" it? SImply have notthing running and 600mb of RAM are in use.
Thanks again, and again: sorry by my english

Yes, animated wallpapers definitely use more battery than static ones.

That's OK. Unused RAM is wasted RAM, and unused RAM uses exactly the same amount of battery as used RAM, so no need to fix anything here. Interesting for battery use is CPU utilization by running processes.

I have to admit the battery life is not brilliant on this tablet. It very much depends on the usage, this wasn't really the case with previous LEAST powerful galaxy tab 8.9. Even during playing games it easily lasted 8-9 hours.
Worst infinity battery times observed ( balanced mode, brightens < 30% )
- playing hard core 3d games, like dead tigger, battery dead in 3-4 hours
- playing less intensive games, battery dead in 5-6 hours
- browsing battery dead in 7-8 hours.
- watching movies, battery dead in 8-9 hours.
so anything between 3-9 hours can be normal with infinity. I cannot even imaging battery life in performance mode, IPS+ full brightens

I was with fear, 'cause for a moment thought that my battery was the only one that is "not so beautiful" But I saw that is not a problem with my tablet and yes with this model.
I'm Brazilian, here the Asus is a perfect nothing. Here we have just the TF101 who comes with 1 year delayed. So I buy the tablet in other country and I don't have warrancy, if my battery was with some problem I don't know what I would.
Here if I call to Asus they would hit the phone in my face before I can say "Transformer"

Ummm...
So you ... own the Asus Infinity TF700T?...or the TF201?
...don't get hit in the face please!...especially with a phone...maybe a small phone wouldn't hurt a lot.
I hope your face doesn't get hit though...

God I love Google Translate... :laugh:
Asus very clearly says "Battery life tested under power saving mode, playing 720p video playback, Brightness:100nits, default volume with headphones." on their website. If you try something else, you'll get different results. Basic scientific fact.
Also, I can't stress this enough: Kill off all bloatware! No you don't need to root the tablet for it (most of it, anyway.) The more processes you run in the background, the more power they consume. Simple as that.
And WiFi EATS battery like you wouldn't believe. It's so horrible it's not even funny. The WiFi unit is very powerful, which is why it eats so much. So yes, using WiFi will eat your battery.
andoid uses RAM differently than Windows. Forget how it works there. Android reserves RAM for processes, even when they're not in use.
Could be the Google Location bug? there's info on that here somewhere too.
Go to settings --> Battery and see what uses the most percentage.

Tips to GREAT Battery Life!

Here are the settings I'm running on CM7 to get amazingly bananas battery life (with the display being on for about 5 hours!)..
1. Conservative governor: 245mhz - 1017mhz in CM7 settings
2. Install the 'BatteryCalibration' app from the market. This app caused the single biggest improvement for me after having flashed so many roms and never calibrating the battery. If you've calibrated it before though, I don't think it'll be very useful for you.
3. Install 'NoBars' from the market to automatically turn on airplane mode when you have no service. (This might be useless to some of you if you always have a signal; Very useful in NYC subway though)
4. Use a 2G toggle widget to have the phone only use the Edge connection when you only need it to receive calls/ texts and don't need the high speeds. I use the toggle widget in the CM7 notification bar. HUGE battery saver.
Give these a shot and let us know how they work for you
I've reached the end of my day and here are my final stats..
Mmy display has been on on over 5 hours now and I have 5% of the battery left. Seems more than good enough for me. Hopefully it will be for some of you too
Edit - Updated with more recent stats

Question: It's cool that your display was on for 3 hours, but what did you do as far as app usage??
If you did use your phone "a heck of a lot" wouldn't some apps like "internet" "maps" or something show up on the battery use %'s???
For example, currently, other than phone idle, cell standby, voice calls and android, there's also internet, mail, maps, and other apps that I used today alot.
Good observation. I have no idea how android chooses which apps to show on there, but I think it depends on the ROM? I remember on Iced Glacier cell standby would barely use 5% of the battery and on CM7 it uses >40% consistently. Idk.
Maybe what those apps used up here was nothing compared to the display, wifi and phone idle time.. Just a guess.. But I did use the browser and xda app and listened to music via the Rdio app running in the background several times throughout the day, and sent multiple texts and have had my wifi on for about 5 hours now. I can't really find a menu that would show these statistics except in the Spare Parts app, and here you go..
I got 17 hours just yesterday with 9% left with moderate to heavy use (texting, web browsing and ps1 emulation).
I didn't do anything besides use faux's kernel with the smartass govenor. I have the max speed overclocked to 1.8 as well...
Nice. I just got over flashing new kernels for a while since the stock CM7 one has everything functioning perfectly and new kernels would improve on something but mess up something else in my experience.
I can't seem to find a 2g toggle widget that works with Royal Glacier. (one touch, I've found a few that take you to settings) When I was running Royal Ginger I would always use the one that came in the notification bar.
Wifi status is also a good app to remind the forgetful to turn off wifi when they leave the Area.

This is GREAT battery life... i wonder what word i'd use to describe mine.
i Pulled my Phone off the Charger this morning @ 7:20pm EST. Now it is 3:13 EST. and i've got ~50% left. So thats what like. 7 hours
neidlinger tap that 'screen on' tab and lets see how long your screen was actually on for?
Either way congrats, and it's good to see ppl are over the battery issues.

since my last boot. 8:10AM when i loaded the new CM7. 1h 1m 59s.
Unless I'm missing something, the 'BatteryCalibration' app won't increase your battery life. It will just help to get a more accurate reading of your battery level.
I've played around with different roms and kernels. And yes, they do have a small effect on battery life, but not all that much.
Here's my tip for battery life. Get on ebay and buy one the of the cheap packages from Hong Kong with 3 batteries and a standalone charger. Like this:
http://cgi.ebay.com/3x-New-1500mAh-Battery-Charger-HTC-Mytouch-4G-Merge-/290556738794?pt=PDA_Accessories&hash=item43a687fcea
I bought a similar package a few months ago and now I never have battery problems. Nor do I have to take a chance on wearing out my micro-usb jack like I've seen happen on a lot of other phones.
Maybe. All I know is my battery increased dramatically after running that app once.
I measure battery life by how many hours I am able to keep my display on before it dies rather than how long after it comes off the charger (like nedilinger does). My battery used to die after about 3 hours of the display being on. Now it consistently lasts 5 hours.
Anyway, I was just trying to let others know what I did to get a really good battery life on my phone thinking it might be helpful. Apparently that's not appreciated. Thanks tho.

How long does 1 of those batteries last?

simple way to get awesome battery life without any extra steps is to install RoyalGlacier 1.6, that's all. A couple days ago I ran my phone for one and a half days before charging it again, and it still had 14% battery left. RG is pretty much a polished version of CM7, runs blazing fast and smooth.

Better than what's reported under CM7. The battery life I posted above was on RG.
you say you don't sacrifice 4g but you admit you have a 2g/edge widget?
To me "not sacrificing 4g" means not ever turning it off, maybe i'm mistaken
I had battery issues, I'd have to charge it mid day else it would die. Juicedefender helped a bit (claimed to do 1.7x battery life) but I uninstalled it, rooted the phone, and uninstalled a bunch of stock apps
For some reason now my battery lasts a very very long time, don't know how or why that is. I also admit I don't use it as heavily as some people, but my habits have not changed and I did have to charge it mid day (like i said) even with little usage

Obviously, it's hard to say without describing how I use my phone, but I get probably 10-15 hours of medium-high usage. I probably get about 4-5 hours of talk time. I'd say the Chinese ebay batteries probably last 80-90% as long as the OEM battery. Quite decent considering the price.
My earlier thoughts about the BatteryCalibration app could be wrong. I don't really know all the details about how Android battery calibration works. I just assumed that it simply learns about all the bad spots in your battery so that your phone doesn't instantly jump from 80% to 30%. I also assumed that the phone would die when the battery had no power left, as opposed to when it says 0%, but maybe that's not the case. Regardless, if it helps you, more power to you and I appreciate you sharing the app. I didn't mean to come off as an unappreciative ****. If I did, sorry bout that.

[Q] Wifi drains battery

Hi,
just got my brand new Transformer Infinity today and I'm pretty disappointed with battery life - without dock it lasts something between 5 and 6 hours while watching youtube and browsing web and that's not much more than my HTC One X. I found out that wifi drains more battery than the screen - 40%, which is pretty weird, because I'm sitting right next to the router and wifi signal is always stronger than -50dB. Have someone experienced something similar?
Battery stats are here: http :// db.tt/TSx6RHtB (please remove spaces, I'm new to the forums, so cannot post links yet).

Same as the prime. Wifi doesn't drain your battery, it's just miss calculated. What drains your battery is the high res screen

Is there a way to check if it's miss calculated or if there is something wrong with wifi module? And if it's actually miss calculated, shouldn't Asus repair it to make sure it is calculated correctly?
your argument might have more merit if you did a test with the wifi always on for a period of time vs without it on.

Since it might be miscalculated that could be wrong. Try watching a movie with another one of similar length without wifi. Afterwards compare battery percentage.
The battery needs a few charge and discharge cycles before you will start to see more meaningful reports. Don't go around and unnerve people by posting about battery life when you cannot possible say anything about that particular issue right now. Let it settle in for a bit. Please.

No, it's not. Li-Ion batteries have hysteresis as well, and the circuitry needs some start and end points to calibrate itself. I would agree that in some cases, like in my SGS2, specific hardware is used that doesn't need as much info as other pieces do, but generally speaking, you can't expect full potential out of the box.
Posted for reference. You can keep believing in your myth busting capabilities; I do not have the illusion I can convince you otherwise.

I agree. As an SGS2 owner myself, I know that when a battery is first used, or removed and put back in, it takes the device a few cycles to properly calibrate the battery gauge to have accurate results. I imagine this is the norm across other devices as well.

Never experienced anything like that since Li-ion batteries came into production.
Btw, just did video tests with wifi on and off, there is almost no difference in battery usage (about 15% per hour with brightness about 50% and IPS+ off), so it seems the battery readings are wrong.
Also I found out today, that auto brightness does not work - stays at maximum level if you go into dark room from bright place forever, exactly the same problem someone experiences with earlier Transformer models. Does auto brightness work OK on your Infinity?

My specimen does the same. Brightness doesn't go down when I turn off the light in the room, and it stays at the relatively high level it was at. So that currently makes three of us.
Using auto brightness on mine now. Seems fine. Regarding the battery usage, i have wlan at. 30% usage after alot of downloading.

Apart from the physical characteristics of the batteries discussed above, it is a problem I have encountered in numerous Android devices - the stock battery stats are miscalculated in so many ways, we won't even have enough time to name them all (I remember users panicking about the dialer "draining" the battery in numerous threads, while in most cases it was only the stat issue showing the dialer using most of the battery after making/answering an initial call).
For some different measures, try different apps from Google Play, like Badass battery for example: https://play.google.com/store/apps/details?id=com.gsamlabs.bbm
According to the review from Taiwan, the Infinity could watch youtube movies for almost 7 hours. The brightness was set to max, volume was set to 50%, using wifi to connect to internet.

Engadget said they got about 9:30 out of the thing. 14:43 with the dock attached. That's looping a 720p video with wifi on, and the screen cranked to 50%. I think with normal usage, you can crank out a good amount of time. You just have to find that sweet spot with battery usage. I know I'm still working that out on my Bionic...but I've gotten that to last all day lately.

After one week of usage mine lasts about 9 hours while idling with 50% brightness, about 4-6 hours while watching youtube or browsing and about 3 hours while watching videos or gaming at 100% brightness and IPS+ on. Right now battery is at 66% after 1:48 of youtube and browsing with about 35% brightness, Badass Battery estimation - 3:06 left. What is battery life on your Infinity?

Wifi battery drain

Hi. I'm having a problem. The wifi is draining my battery. My battery will only last about 4 hours of screen on time.
I've already check the power option of disabling wifi when the screen is off. Wifi drains at least 40%of the charge.
I've read other forums but nobody has an answer just yet. I really like this tablet, but it makes me mad just having 4 hours of battery.
Driver problem, an app misbehaving, hardware problem?
What can I do? What should I do? How many of you are having this issue?

Depending on your usage, it is indeed possible to drain battery 3-4 hours. I myself never had that situation but for those who played highly CPU/GPU intensive game along with WIFI had that issue. I usually had 5-6 hours on my routine use which to me seems was not much.
So couple things I believe you should look into.
1. How is your monitor brightness?
2. What applications are you running? e.g. are you downloading on background with playing some game foreground?
Those sort of basic things. To identify whether the WIFI is actual issue or not, one thing you can do is simply turn off the WIFI and do whatever you need for couple hours and see where you at in your battery. If you have 50% drained in couple hours without WIFI on, clearly WIFI is not the issue but if you suddenly get only 20% battery drain from WIFI off, it is indeed the WIFI.
If WIFI is indeed the issue and perhaps you can try Juice Defender but it will only save battery if you are not using WIFI all the time.
For detail, please refer to http://forum.xda-developers.com/showthread.php?t=1805636.
One last thing is obvious, but battery save mode rather than balance mode gave me extra couple hours without sacrifice in my foreground application performance; however, I did notice main screen page swiping or application launch animation weren't as smooth. Almost felt like back to my old Galaxy 10.1 tablet on Honeycomb.
There is actually a bug that makes your battery overview show the percentage of wifi on time as percentage of wifi battery consumption:
-> wifi on 80% of time > shows 80% of power consumption from wifi.
How long do you have your device ?
When i first got it I also thought that the battery time was bad but now ( i have had it for about a week) i get battery drain of 10% / hr while surfing and 14-18 %/hr while streaming video over wifi and 0,5-1% / hr while standby with wifi and sync on.
I have the brightness on manual contorl and when i watch video i change the performance to eco setting.
Hi, thank you for your responses..... This is an update of what is going on.
I am already on firmware. 26, but had the problems since fw. 22
Yesterday I did a factory reset to rule out some mysterious app. The battery issue continued under wifi.
Wifi was still draining between 40 and 50% of the battery. Completely drained in about 4 hours of browsing time in balanced mode and about 40% screen brightness.
I just did another test. I played 2 movies with the wifi off. After 4 hours of screen on time the battery fell to 66%. So the tablet have enough battery juice for 12 back to back movies. That's great, I can rule out the battery.
So far I can confirm that the battery is draining extremely fast with wifi and is not a big showing erroneous battery drain.
4 hours of browsing tine is a joke for a tablet...
Any other things you think I can try?
For how long have you had it? No matter what people say, the calibration algorithms for these kinds of batteries still need several cycles of charging and discharging before they can actually read out any battery level accurately. I easily go for far longer than that on my device -- not that that fact helps you out, I know -- but I thought battery life was worse in he beginning as well. I guess it just needs to settle down a bit. Give it a week.
EIDT: Oh, and....eeehmmmmm.... do not believe the standard Android battery tool. Get yer mitts on BetterBatteryStats and get a few cycles on it, check the readouts and then report back in.

Thanks. I've already installed better battery stats.. While Web browsing battery drains up to 30%/h. I know is too soon to get to a conclusion. I will keep you post it.
Hope there is some firmware update that will fix this. This is Asus 5th tablet (transformer, prime, slider, tf300) I don't want a beta product!
Sorry about the whining, I know that you guys are helping me..
Battery life is really bad on this we need the motley kernel and some custom rooms soon !!!
I am running this tablet on performance and it is still very slow ccompared to my prime I hoped I can wait for the custom rooms and kernels before I sell this tablet i know i am very impatient
i have a tf700 too and have the same problem on wifi I love this tablet, i think we need to find a fix. Hope to hear from some of the smart people on this forum.
The reason for the low battery is this; Asus did not put a larger battery in Infinity compared to Prime.
Both devices have the exact same battery, but since Infinity runs at a higher clock speed and has a higher resolution screen, it drains the battery much much faster.
You can't really fix this with software. You can however lower the voltage with a custom kernel, making slightly improvement....but that'll also make the device unstable.
Just to let you guys know, i have assigned a fixed ip address for my Tf700 and the wifi drain seems to have decreased. I won't rely on the native android battery monitor (mine still says 85% battery drain by wifi). But i have noticed much less actually drain/hour when using wifi with a fixed ip address than not. YMMV.

Battery sucks! Faulty unit or crappy software? HELP

I have used this tablet for 2 days now and almost everything works perfect (thanks to latest ota) but there's one thing that is bothering me. Battery life. I had ipad 3 for 2 months but I finally sold it and bought the infinity. Now I know ios sucks on phones AND tablets. But the battery life was amazing. I could use it to browse and for games for 9 hours at least. But on the infinity I am lucky if I get 4 hours browsing. 4 hours sucks on a tablet. But I think that wifi is the problem. I have added 2 pictures were you can see I used the tablet for 1 hour last night then I used it for almost 3 more hours today. Now the battery is at 10%. But I was wondering why the battery uses 62%? On my galaxy nexus wifi is using 5%.
Have I got a faulty unit or is it like this for everyone? If so please let me know fast so I can send it back before it's too late.
Somethings not right there. Tests/reviews done by some major outlets (thinking PC World or Engadget) reported 9 hours of video play over wifi with screen at 50% brightness. iOS has always had good battery life due to their stict contols over the OS, but you should be seeing more then 4 hours. Hell I was at 40% and played WindUp Knight for hours straight last night which takes up much more battery then a movie. I usually don't suggest using task managers, but there is one built in by asus, I'd use it and see if you can kill some processes. Also be mindful which profile is being used. I stick to balanced most of the time and switch to low when the battery starts getting low (24%ish)
http://www.engadget.com/2012/06/25/asus-transformer-pad-infinity-tf700-review/
The TF700 packs a 25Wh battery rated for up to nine and a half hours of runtime. Indeed, it lasted nine hours and 25 in our battery rundown test, which involves looping a video with WiFi on and the brightness fixed at 50 percent.

Thanks for the reply. I am always on Balanced and i am seeing over 20% down in an hour. Maybe i have a faulty unit?
I wouldn't be so sure. I was playing nova 3 on performance mode though.

Exactly, it all depends on what your doing OP. The movie scenerio in the review doesnt take much juice in that it uses the low power single core. I don't know for sure, but web browsing may require all 4 cores to kick in depending on exactly what your doing. Regardless, your wifi being a big consumer is easy to deal with. Somewhere in the settings is an option that automatically turns wifi off when screen is off.

Well, all i was doing was using chrome... I think it's pretty bad when i cant browse for more then 4 hours on a tablet. I thought it had to do something with WiFi since its using over 62%. I did the same test with my nexus where i i just used chrome and when i looked in battery , wifi only used 10%. Maybe there is a bug with wifi?
Try Battery HD for some averages/estimates.
I tend to get about 9+ hrs of reading, balanced mode, WiFi off, and about 7 hrs of browsing over WiFi (undocked, dock charges me about 2/3 full), but it all drops down drastically for gaming, which is about 4 hrs you mentioned.
If you get 4 hrs of pure browsing, I'd consider re-flashing, wiping data and - if these don't help - returning your device.
Chief Geek's point has much merit, and you could always look at (for example) GreenPower or some other time-/screen-based toggler. They do pretty well, and you do not even lose out anything except direct push functionality. (Does it really matter for 99.9% of mail when it comes in once every 15 or 30 minutes? When it does (when you're buying a house or something), shut down the toggler for the time being and cope with some battery drain, then when the situation has resolved, enable it again.
And try using BetterBatterStats for your statistics -- the main battery stat app Android offers has some quirks to prevent meaningful interpretations of many scenarios. Let that get a few charging/discharging cycles and then look at the stats.
So battery hd tells me I should get 8 hours of browsing and 9 for video playback. Will do another test tomorrow with screen on whole time and see how long it will last watching videos. Also battery hd tells me I can play 3d games for only 2 hours. Eh

Remember that these are just averages for your device, at least in the beginning.
If you mistreated your battery upon receiving it, it can kill battery life. You are suppose to plug in your asus tablet for at least 8 hours (well beyond the tablet would say the battery is 100%) the first time you get it. This is sound advice for any new Lithium Ion Battery.
Then you can start using it. Letting the battery die at 0% also decrease the life of the Li-Ion battery every time it happens (ignore old sites that say you should do a full discharge cycle every 2 weeks, that was for old Nickel Cadmium batteries).
Juice Defender is typically a phone app but you can run it as well to detect if any background processes are eating up your battery life.
I get almost 10 hours on my TF700 with moderate usage (mix of browsing, video playback, reading, etc.).

All correct -- there is a lot of disinformation going on with batteries (especially regarding the charging cycles, although a single, long, full charge and then draining to zero charge actually helps calibrate the battery indication algorithms in the device). The optimum minimum charge level seems to be about 40% or so I've read.
Juice Defender and Greenpower toggle WiFi on either time- or location-based profiles, and that works on tablets as well. Recommended!
Your phone doesnt actually discharge a battery to zero. The thing with lithium batteries is they maintain voltage untill nearly the end. This is a very large benifit for modern devices. Once the voltage starts to drop the phones circuitry cuts it off and prevents it from powering on with the LVC circuit that checks the battery before allowing phone to power on then immeditately cuts it (first attempting a power down then all out power cut). This happens to protect the battery. So what the phone considers a dead battery is simply an exhausted battery ready for charge. If a lithium is actually dischardged completely it will damage the cell and prevent it from taking a charge. The power being given to it is then converted to heat. The battery then ignites and very very bad things happen such as your house burning down. The point of all that is to point out that discharging your phone to "zero" isn't actually doing any damage past the normal wear and tear on the battery. I buy batteries that cost hundreds for some of my RC hobbies and have learned the hard way about how lithium batteries work. (bypassed LVC and ruined a $80 3S2P pack)

i have actually read that Li-Ion batteries can be used out of the box. Sp i turned on my infinity right away. I put the charger in, but i still used the tablet. It was about 25% when i got it out of the box. So what you're saying is that i have basically ****ed up the battery? If so, then i will return and get a new one. But i dont understand why most people say that you can usre a device with Li-Ion battery staright out of the box without needing to charge it first.

Nothing to add, technical and extensive, but fully correct, sir. I think we may have had a slight misunderstanding, however: my point was that discharging your phone to 'zero' (and as you rightfully point out, that is not an actual fully discharged battery state) is a required step in calibrating most device's algorithms (some devices, such as my SGS2 do not need this because of advanced hardware). I'd rather not fully discharge any Li-Ion batteries either.

A typical case of RTFM, an affliction I sometimes suffer from as well, as do most men. Hahaha! Do you think ASUS put it in the manual for laughs, or just to give you a few more hours of painful desire to use your device while you cannot, yet? Nah, it's there for a reason. Sometimes, though -- and again that's SGS2 experience -- just running a few battery cycles might make the readout correspond to the actual battery level again. You could at least give it a try, right?

I see the same picture here. Looking at the battery stats I see WIFI using >90% of the battery when surfing in balanced/50% backligt mode.
Hope they fix this.

Great battery life with MM update

Hello ..
I am getting amazing battery life since I got 6.0 .. Before with lollipop I used to get around 5 hours on screen time. Amazingly though I hit 6.30 hours on the first day after update, and this with wireless, mobile data and Bluetooth on. And no data saving and screen on 70% which is amazing.
Good job Motorola
Excellent I would say
Excellent batt life with this new update very impressive how a software help the hardware to accomplish that task.
I replaced my STYLE and got a new one two days back. The old one would be dead even though it has 80%+ battery.
The current one is pretty good compared with the old unit. I got 4+ hours of SOT and I was on 4G and WiFi all the time. Was using it heavily for browsing and chat.

This is not bad at all. What I am saying is after MM update battery life increased about 1.5 hours extra SOT
Perhaps the update fixed something else? Looking at the MM update from L, there appears to be nothing besides Doze, which only works when the device is still and not used. I notice perhaps 15% better battery life if using the device sporadically during the day (medium use for me). With heavier use, I notice zero difference so far.
I was hoping some kernel adjustments were made, but the device spikes with heat about the same. I first thought it was less, but notice the same apps get the device very warm to hot (the GPU is over it's head with 1440p). Standby time is a lot better though, but only a significant improvement if lighter use though the day (so Doze can be a factor).
Usage is relative only to the user though
How do you get such great battery performance? I barely manage to get 3 hours SOT.
When the device is idle there's no drain, i only lose 2-3% overnight. But when the device is active the battery drains very quickly.
Tried a lot of battery saving stuff, greenify, powernap, and so on, but no luck.
I'm on MM stock rooted. Having a lot of apps installed. May this be the culprit?

If 20% brightness or less, all you do is web surf and a little Youtube, with good LTE signal or wifi and VERY little use of apps that force the GPU to push 1440p, you can get five hours. Everything is relative to the user. That's it.
Counting stock apps, I have 395 apps and 5GB free (64GB model). based on MM battery report, I have no apps that are background battery demons.

Are you talking just 1440p video in general or are you talking 1440p games?
I'm lucky if I get 2 hours of SoT. I can't tell if Android Wear is eating my battery or if it's Sprint, despite having a decent signal. Bluetooth and Cell Standby are chewing up the majority of my battery power. I think the network management is trying to shuffle my phone between their three frequencies and while at work, I can only get on the 1900MHz PCS band due to having to use a repeater.

Some games and apps run at 1440p and choke the GPU. They stand out by running very warm to hot and drain the battery more quickly.

Yes the apps do drain battery.
I uninstalled one particular email app that alone would drain 6% daily!
Anyway this time I got is without gaming. Mostly chatting and browsing and a lot of movies (vlc). I think that day I watched not less than 3-4 hours of continuous movies on the phone.
The only thing I did differently than before is removing unnecessary app permissions and notifications. Other than that I have done nothing. Like I said I do not try to save battery because I always have power source near by, but this 6.30 hours SOT i s awesome I tell you.
Based on my little experience with Android some apps will screw up the phone for no reason. First time I got the phone I got around 3 hours SOT with so many unneeded apps, and I did not know which app is draining my battery so I formatted the phone, and started installing apps one by one and watching the battery. And I managed to hit 4-5 hours with lollipop. Now with the update I got this and I was shocked.
Fully back to stock, unrooted, bootlocker relocked.
Upgraded to MM via OTA.
Installed all my apps via Play Store. Until now, i always restored my apps via TiBu, including data/settings.
I'm curious if my battery life will improve.
Will post the outcome, if any
Cheers!
A lot of the time my phone is just sitting on my desk. It used to say I would get around 1-2 days battery life from it sitting there doing nothing. After MM it says there is 8 days left. I have had it unplugged all day and even with some moderate use I am only at 95%. The doze mode really makes a big impact in stand by times!

I think it did do something to the apps. The way you can block apps from getting access to location or other services is pretty impressive. I love that as I hated that apps would have access to everything on my phone and I cannot do anything about it. Now I can and this particular feature made me love Android even more after I switched two months back.
Is there something wrong with me. I only get 2 to 2 1/2 hours battery tops and actually I've tried amplify (paid version), and power nap and they don't seem to help much. I have only got 3 hours once since I got this phone. Is it just AT&T maybe?
I'd like to mention something else. Probably not related at all, but ..
My old MXS was a faulty unit (as I mentioned in my previous post). Once I got a new replacement, I have not yet charged the phone using Turbo Charger. I am charging it with Mi Pad charger (non-turbo). Yes, it took about 2+ hours to go from 30 to 100%.
Old MXS was always charged with turbo charger and I was getting pretty bad SOT and the baterry would drain as fast as it would charge. Does it have to do something with using a normal vs turbo charger?
I stop pretty much all background services and apps not in use. The only active applications are firefox, whatsapp and VLC.
My screen is set to 50% brightness with adaptive brightness ON. Moto X display and attentive display is ON.
Non-root (planning to root soon) and Moto ROM.

Less than 3 hours is not good bro, really anything below 4 hours is just bad. You better figure out what is draining your battery, or maybe it Is a bad unit?

what difference does it make if it is charged slowly or not??
It should not matter, if the battery is not keeping the power that means it is defective, nothing to do with slow or fast charging.
