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.

Well, what do you expect? It's going to take some power to push all the pixels on this massive resolution.

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.

let's talk battery..

so as it may be known, i came from an iPhone 4S and traded that for an HTC One X, i've had it for a little over a week and i really like it a lot BUT (you knew that was coming i think..) the battery is below par, i get about 3, on a real good day 4 hours of usage from a full charge. i only auto sync mail, screen is on 25% (also tried auto for a few days), when at home it's connected to WiFi, data off and when i go out the other way around, GPS and Bluetooth are off at all times. the main thing i do on my device is Twitter, Google+, Facebook and Instagram, + some light browsing the Internet. i understand the screen and processor take quite some battery but it's not cool to only be able to use the device about 3-4 hours before running empty. emailed the guy i traded with and he said he got about 7hrs, which would be awesome after dealing with 3-4 ;}
i am using Nova Launcher Prime, but prior to that when i ran Sense the battery was about the same. may just revert to stock to see how that will affect the battery, even though i will miss my widgets and setup. i also emailed HTC and was considering going to AT&T but since i traded the device i doubt they'll be much help.
what do you guys get... and what if anything did you do to improve it ?
thanks.

How much screen on time? 4 hours is nuts. I easily got 24 hours on stock, with light usage, maybe even a day and a half. The 2.2X versions firmwares seem to get better battery life. Just this morning I had just under 50% battery left after 24 hours, with 1 hour screen on time.
If screen brightness in on "Auto" turn that off, and set it to something like 40-50%. That should save you some, but doesn't account the type of battery drain you are talking about.
Might be some runaway processes. Or any possibility you are in a fringe LTE area?

on screen time is what i was reporting, round about 4 hours -which yea is pretty horrible i'd say. i even have the screen brightness lower; 25%. checked the processes and for what i know nothing out of the ordinary, but i'm a novice Android user so.. prior to yesterday i only used 4G when out, so at home i stayed on WiFi.
battery stats now:
- 76%
- 5h 8m 54s on battery
- screen on 59m 28s

Screen on time of 4 hours very normal, and its good for a smartphone. Everyone uses their phone differently, of course. But 4 hours of screen time gets most people through a day, and charge overnight. What type of screen on time did you get with the iPhone?

Your stats are very normal for this phone model. The One XL screen is gigantic, but isn't AMOLED and as such uses much more battery life to power than some other Android devices. I get ~3 hours of screen on time in a days use of battery, and that is about 10-15 hours away from a charger. From what I can gather of your usage, if you are looking to extend your battery life, the only thing to do is leave the screen off more.
Do you flash custom ROMs? If so, try a custom kernel that allows you to change the CPU governor and clock speeds. The processor in the One XL maxes out at 1.5GHz by default, but you can underclock it to 1.2GHz with no noticeable detriment to performance. Also you can set the minimum frequency to an even lower clock speed, which allows the phone to use even less power when idling. Finally, make sure that the CPU governor is set to Ondemand. Powersave actually doesn't save as much power as you would think!

my favorite part was when he compared a tiny 3.5" screen to a 4.7" screen and expected the same battery life, even though it is roughly the same

Firstly, 4 hours screen on time isn't bad at all. I'm sorry your only reference is an iPhone.
To get 6+ hours of onscreen time with this phone like I and many others get you will need to do two things. Firstly, flash a custom ROM. CleanROM 4.5 is a good one that's as close to stock as you're gonna get. The second thing you need to do is turn off auto brightness. Leave the brightness set at 35% - 40%. This will improve battery life immensely. And no, 40% brightness is not dim.
Happy flashing!

with my iPhone (GPS on always, WiFi always, screen on about 70-80%) i got an average of 6 hours with peaks of 7. 4 hours with the HTC One X is on a good day.

i did not flash a ROM since i can not unlock the phone (yet). where i compared, referred to the iPhone is based upon the previous owner who said he usually got 6-7 hours on screen per day. it's uncool that people not live by the rule if you don't have anything nice to say, don't say nothing... i'm only trying to get some help here (luckily most members are helpful... i'll try and ignore the others) and my other reference would be a BB Storm, which lasted very long, but the device wasn't very exciting
i'm following the thread where rooting is discussed but i believe there's little progress. AT&T is also not pushing Sense 4.1 (yet, mine has 4.0) and ICS 4.0.4.
just spoke with HTC and they agree it's too short and are willing to exchange battery... downside i would be w/o a phone for 7-10 business days. might swing by AT&T and discuss, "issue" is i was not the original buyer.. he (HTC rep) stated they might give you a loaner (i doubt it..) we shall see.
thanks to those with positive feedback.

so far..
click here for today's results --16% left.. slightly over 3hr on screen time.

It really depends on how you use your phone, and not all screen-on time is the same. 4 Hours is screen time is pretty good, and pretty on par with what other users on here have observed. The phone is new to you, so I bet you are using it like crazy. If that use includes a lot of internet, playing video, or games, its going to use more battery than some other activities. I don't know if a replacment is going to make you any happier.
You also have to consider, aside from a much larger screen, its also much higher resolution than the iPhone. Pushing all those pixels by the GPU takes power. The CPU is also much faster than the iPhone (and just about any other smartphone except the Galaxy S3), again using more power. Screen time may be less, but its doing so much more in that time.

4 hours, if I made would be somewhat acceptable, yesterday I had a little more then 3. I do not play game, I manly do social media & a little surfing..

The 2.20 OTA has an new radio. So its possible that the new radio happens to result in worse reception (and therefore battery life) than the previous one. Newer radios do not always get better results for all people, as its very geographically dependent.

Thank you for the reply and yes the radio looked like it was a new one and in PA i dont get that great of service everywhere.

Yeah, 4 hours of screen on time is normal so I definitely don't think you have any sort of defect. Signal strength also has a lot of impact on battery life. Keep brightness as low as possible while still being comfortable to your eyes (battery life isn't worth putting extra strain on your eyes). I use an app called display brightness that allows you to change brightness by swiping across the statusbar. I keep mine at the lowest level and just swipe a bit to increase it when I need it and then swipe it back down when I'm done. A custom rom could help some. If nothing else, root so that you can use something like better battery stats to give you more info on what's happening behind the scenes so you can make some adjustments. Although I'm not one to push using this, you might want to install something like juice defender to see if it helps. Verify you don't have some app running in the background unnecessarily chewing up cpu use. Note though that just because an app is running in the background doesn't mean you should kill it. As long as it's not doing anything, it's better for it to be running than to have to load it up (especially if it's an app you use frequently). A couple of other things to verify, don't use push notifications / syncing (I keep background syncing off a manually sync (well, I use Tasker to sync things at different times of the day)). If you can, use wifi. If wifi isn't available, turn it off. Also make sure wifi notifications are off and that you aren't using 'best wifi performance' (both under wifi advanced settings).
I'm sure there are some others I missed but hopefully these help and at least give you a starting place. No matter what though, enjoy your device and don't obsess too much with the battery. Once you've gotten over the 'new toy' syndrome, you should get a days use out of it. I pretty much take mine off charge in the morning and put it on charge before going to bed with around 30‰ left. Sometimes more, sometimes less. 3-4 hours average of screen on time, 30-60 minutes of calling.

update.
went to the AT&T Device Center (did not know it existed until the regular AT&T store told me about it...) they played with my phone and concluded that the battery was draining too fast while using it, so w/o discussion they exchanged it.
got a follow up question since AT&T did not know, with the iPhones i would let them drain all the way down at least and then fully recharge and leave it on the charger for an extra 2 hours after it being 100%, i *think* that helped condition the battery.. anything you guys can suggest anything for me to to now that i have a new device to maybe improve/condition the battery ?
thanks.

[Q] Weak Battery

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.

You haven't posted a lot of details, but bear in mind the following.
Games usually draw more power.
Otherwise I would be looking to do the following.
Charge to 100 %
Then use it until it runs down to 15% or less. That should take about 8 hours (at least - but I don't play games on mine) so may be just do some browsing.
Repeat a couple of times to calibrate the battery.
If it discharges much quicker then you need to start looking at your settings.
Is power saving enabled (It's not in mine cos I think it's a pain in the ass)?
Is Bluetooth on all the time?
Is GPS on all the time?
How bright is the display and is it set to Auto? ( I find that mine is bright enough at about 20% for normal use)
Happy with all that ?
If you still feel that it's discharging to fast then look at installing an enhanced battery stats program that will try to identify any app that is acting as a battery drain.
Report back your findings

That can´t be, there must be something wrong with Your Note.
My wife unplugs hers at 6 am, plays games for 1 hr while we drive to work, works with it the entire day, plays again games for 1 hr when we go back home, then surfs the internet on UMTS and goes on playing games until around 10 pm and still has got 25-40%.
Before with her iPad she had to recharge already in the afternoon with the same user-profile.
Check batt consumption with the app "Better Battery Stats" and eliminate batt-suckers

I get about 10 hours of use daily with mines which is good.. but as for the ipad being better on battery that is true because it has a bigger battery than the note 10.1.. The note 10.1 battery is 7000mah and Ipad is 11666mah that is one reason why many people always say the ipad as better battery life.. Because they dont know the ipad battery size is bigger than android batteries..

[Q]Nexus 5 Battery life

Hi All,
I am gonna get my Nexus 5 ( 32GB Variant ) in about 2 weeks and I've done extensive research on numerous reviews and found out that the battery life is mediocre ( in GSM Arena it says 40H on the endurance test )
Is this battery life issue easy to get over with by installing custom roms?
Thanks alot!

Lots of stuff already posted if you search.

From my experience, i get great battery life on mine running stock.
Sometimes I reboot because of a qcom-camera-something-like-that bug draining battery or whatever it is but no serious deal breaker
I had one time 1 day 14h @ 44% with light usage, wifi turned. Most of the time i do play a lot, read mangas, have whatsapp, hangout, facebook, snapchat, instagram and all these apps installed pushing notifications, It still gets me through the day easily.
I was worried about the battery when i bought it but keep in mind, even if the LG G2 has 3000 mah, it has to run all LG services and tricks like "double tap to wake up", this device is PURE Google. See it like an enormous engine with only wheels, no fancy sh*ts, it's up to you if you want to make it lightweight or heavy as ...
Anyway if you're still concerned about the battery life, get a wireless charger for 40 bucks and put it where you stay the most (desktop at work/next to you computer). You will just have to lay it down to make it charge with no efforts

I'm guessing you had the screen brightness set to its lowest.

Battery life is what you make of it. I can make my phone last 8 hours or a day and a half.
I feel like there are over a hundred threads inquiring about battery life. At least two a week.
