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?

It's only a stat, doesn't mean that WiFi *drains* your battery..

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.

I tried to turn off wifi for a couple of minutes, battery stats show wifi consumption 0. After turning wifi on, wifi battery consumption goes very fast to 30 and later to more than 40%.

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?
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.
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.

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.
I am still w bit confused wheather 2 units I had was faulty or not. ASUS definitely has bad QC. I was under the impression with constant browsing with low screen brightness and balance mode, we can only get 5-6 hours of battery. But some review sites state more and I even so similar discussion back when original transformer was released. So I want to verify.
Does anyone get over 8 hours of battery in balance mode, low screen brightness while constantly browsing? The easiest way to test is browse for an hour and see how much battery loss. If 20%, you get only 5 like I did.
last time i checked, i had 7.5 hours of screen on and wifi was actually my biggest battery hog by a 2:1 ratio, and still had 30 something % left. i dont have battery issues, i'm not sure if my transformer is a very recent build but i dont have ANY of the issues reported on this forum. no clicking, bleeping, battery problems or any other. my only problem is really just software related just like a lot of other have, lag, reboots, force close, but i know asus will fix that shortly

Did you have a dock? That's impressive number even if you didn't use browser at all. Still far superior to way I had. Do you mind browse formalize 30min and see how much battery drop you see? Also ,let me know which mode and brightness you used.

no of course no dock on...if i have a dock on i can last days. The most i lasted with a dock and moderate use like reading about 1-1.5 hours of zinio magazines, checking a few youtube videos, some fbooking, twitter, tapatalk and some browsing all that per day was at least 7 days...i'm not sure how much time exactly because when i use the dock the battery stats seem to reset every time i close the lid or at random times....
Look at these stats. My usage was: downloaded 2 issues of my subscriptions on zinio, downloaded tonights breaking bad episode off torrents, saw a few youtube videos (about two 5-7 min vids), facebooked a good half hour, read half my issue of XXL magazine while sitting on the crapper and while waiting for my ribs to cook for a total of about 45 minutes of reading, + making about 6-7 benchmarks test on antututu to play around with set cpu (all but 2 tests were on performance modem the rest were on balanced), and your requested 30 mins of non stop browsing which consisted of looking for a wallpaper and browsing on ebay, all that in 3:26 hours and i got 26% battery drain, brightness was at about 30%, and this is what i consider it to be HEAVY use as screen on time is 1:56h.
Usage before your 30 mins of browsing
after your 30 mins of non-stop browsing:
So about 8% drop in 30 minutes of browsing and this is including 24 wallapers i downloaded from google images.
P.S. I'm rooted, not unlocked and i'm not debloated as i,m waiting for JB to really start playing around with the pad
mine would drop about 10% every 30 minutes watching videos - netflix or local.
my note, however, droped 25% after 3.75 hours of straight usage. this was with 3 episodes of The Unit, drawing, web surfing, and streaming netflix. i had to do all this while my daughter played around at monkey joe's.
all the reviews i've seen show the that the infinity gets 8hrs at 50% brightness. all my usage on both infinities and the gnote were all under 20% with headphones.
With dock, I am able to get 10 hours of straight use (non stop) playing various games. Played Angry Birds, Dead Trigger, ShadowGun, Amazing Alex, Drisk, etc. No wifi was on. I get about 6.5 hours on tablet alone.

How did you manage to put android in charge of battery instead of asus, simply disabling asus battery?

It's a joke. All the ignorant ipeople always say android gets horrible battery life on the tech forums I go to. I find it funny that my tablet actually does get bad battery life. Then again, I never use powersaver mode so I guess its fine.
le rustle face
Thanks all for taking time to post a reply.
So I guess what I experienced with 2 units were indeed what it is. For some, perhaps many, infinity's battery life may be enough but unfortunately for my use it was just too short. Video play time or ebook reading time were totally fine. Its when we use browser, the jump to 20%/hr drain i.e. mere 5 hours of battery life with tablet alone. This won't last me a whole day. Sure dock would give extra power, but I got Macbook Air so if I want to carry actual laptop, I would actually do so. One reason I have been purchasing different tablet is mainly the use as tablet.
I don't know if it is fixable by firmware, but Samsung certainly does seem to achieve pretty similar battery life whether using browser or not, so I wonder it is something at the software level that ASUS is missing.
But I really appreciate all for answering this question.
Thanks
I too spent a considerable amount of time researching this as I thought my unit may have been defective. Long answer short it gets about 5 hours if you're web browsing even with low brightness.
I'm hoping a software patch can improve it at least somewhat, as having the WIFI on seems to drain the battery excessively compared with it off.

Yeah definitely that's what threw me off. We all talk about/assume higher pixel density thus more battery drain, which made sense but infinity's battery life with book reading weren't bad at all. It's the WIFI, which is very strange.
Hi
The Wi-Fi usage seems very high on these. No way should the Wi-Fi be using more power than the screen, certainly doesn't on my HTC One X, which due to laws and regulation will be transmitting with the same power as the TF700, but the screen will be using a lot less power than the TF700 as it's smaller so needs less back-light, so if anything Wi-Fi would be an even bigger percentage on my phone compared to the TF700, but rarely is Wi-Fi a quarter of the screen use, often much less.
Unless that Wi-Fi is doubling up as a small microwave oven, power usage should be quite a small percentage, so either the TF700 is mis-reporting Wi-Fi usage, or their is a fault (software/hardware?) with the Wi-Fi card.
Regards
Phil
no , we can not
I think we can not , it is too fake to say the battery would last up to 9.5 hrs.....
The wifi indeed has some problems, which would comsume more than half of the battery life.
Maybe.... asus intends to increase the wifi power to improve the performance!

Well many on this forum says its miscalculating, which may partly true but not entirely because as Battery drain was my concern on this system I did multiple trial and basically WIFI on with active browsing crank up the drainage to 20%/hr from 10%/hr without browser i.e. WIFI on but just reading ebook. So WIFI is truly consuming battery.
On my Galaxy Note 10.1, whether actively browsing or not the battery drain still remains 8-9%/hr. So yes. WIFI may consume more power but should not be twice... unless WIFI unit ASUS using is some weird one.
The storage brand and Wifi units are usually something most companies don't put on their specifications so hard to tell whether ASUS tried to use really cheap ones there to keep the paper specs great, yet functionally not meeting up the expectations. Or ASUS may simply have yet to catch up software people. Whether truth or not I heard Samsung hired quite few programmers relatively recently. And compared to my old Galaxy Tab 10.1, I definitely see marked stability/smoothness improvement on the Galaxy note 10.1 which also uses ICS just like transformer infinity.
The most interesting comparison for infinity would probably be though Xperia S tablet. Because that one also uses 1GB RAM, and Tegra 3 (inferior to one in infinity) and runs ICS. So if ICS there is as stable as Galaxy Note, at least we know its not memory, its not tegra architecture. Though storage will still remain as potential source.
But going back to the subject, battery life on infinity on the contrary to some here stayting dock providing extra battery, I find not great. Even with docking station, it either barely matches up with that of Galaxy Note 10.1 tablet alone or perhaps less especially if you play games.

I think in the TF700 they are using a Broadcom SoC for Wi-Fi, what ever it is though, drivers will be provided and it isn't much different to plugging in a Wi-Fi stick to a USB port. Perhaps they have configured it wrongly or there is a hardware error or software reporting error with the Wi-Fi. I can understand why people say it is a software reporting error as most people acknowledge it should never be that high as a percentage of power use so don't believe the figures. If they are the correct figures for Wi-Fi usage then something is very wrong somewhere.

I've been having the same problem. Wifi really does seem to drain my tablet too. I usually turn it off as I use juice defender and it helps immensely but it is kind of ridiculous for wifi to eat so much, especially when I want to start using the internet.
I got my HTC One Mini yesterday and I'm getting pretty good battery life so far, how is it for you guys?
I'm using jmz's Stock Rooted Odex WWE Rom and Jmz M4 Kernel 9-04-13. I unplugged my phone around 9 AM this morning and it's now 1:45 AM and I'm at 48%.
I installed 12 apps, torrented a 315MB file using uTorrent @ about 600 kb/s, watched 23 minutes of 720p video using MX Player with hardware decoding, watched about 15 minutes of YouTube videos, went on Facebook for about 20 minutes, browsed the internet for about 5 minutes, browsed a forum using Tapatalk for about 15 minutes, made about 5 minutes of calls, sent/received about 20 texts, read a manga chapter, used it as a flashlight for about a minute, used it as a remote for XBMC for about 2 hours, flashed a kernel, and took a couple of pictures, a 30 second 1080p video, and a Zoe to test out the Camera. All of this was over Wi-Fi.
I think I could easily get 2 days out of the battery as my typical usage would be lighter. How is the battery life for you and what Rom/Kernal are you using?
Stock UK Vodafone Rom recently updated with the it's package.
Well...I am sadly unimpressed by the battery. I've had mine now for just under a month and don't get a day.
I use it to surf the BBC website (in mobile mode) over 3g and at other tines WiFi.
I make calls about 30-60mins a day and play a version of bubble breaker.
I can literally see the power drain when surfing the web. This us the single most draining activity...much worse than when I used my desire.
I have configured all power save options, disabled all non essential apps, and ensured the phone is not burning background or unnecessary apps.
Still it goes rapidly. It's a shame but I like the phone so will live with it.
2 days...yes if all you do is make calls. Anything more demanding not a chance I'm afraid. I have tried, a lot.
So it is now 1.10pm and I have 52% and at 9 am I had 100%. No video no gaming but a mix of BBC on WiFi and 3g (i have a femtocell so no burning power while looking for a signal).
Nice phone in so many ways but battery life, in call quality and control, are very poor.
All the best,
Sam
I am planning to buy HTC one mini, Wanted to get real idea of battery life, so this was helpful. Could you laso tell me if that 1GB RAM is a problem maybe once you have 60-70 apps ? I thinking of 2 years life at least so was concerned?

For me it isn't too much of an issue, but they really should have equipped it with 2 GB of memory, 1 GB has been the standard for about 2 years. I have 42 user apps installed and most of the time I can have multiple apps open without any slow downs. Occasionally if I have multiple heavy apps running (Maps, Facebook, Pandora, Chrome ect.) it can slow down due to the lack of memory, but if I close one it speeds right back up. If you read any reviews you'll hear something along the lines of it's stupid that they only gave this phone 1GB of memory, but for most people it won't be a problem which I agree with. I'd suggest trying it out at a local store before buying it. Different people will see things differently, to some the HTC One Mini and S4 Mini will seem slow compared to the regular One and the S4, to others it will seem very fast.
ok guys please keep in mind that your mobile connection eats your power rly ****ing bad. I did a lot of tests with the mini and i'm was even able to get 5days with 25% left. Camera or wachting videos coast a lot of power as well but music is ok that does not need that much power.
Its all about your connections and how good the signal is, so if you want a longer battery life only use wifi.
The device has smaller screen size, lower resolution, half the number of cores, lower clock speed, lower powered GPU, half the RAM, no NFC or OIS. It should get *better* battery life than the full-sized one all things considered, though the smaller battery will definitely even this out somewhat. I wouldn't be surprised if under typical moderate-high usage involving CPU and screen this device should hold out similarly to the HTC One but in standby, etc it will be a bit lower.
Notebookcheck and GSMArena have done thorough battery testing, though notebookcheck doesn't test standby time and GSMArena's standby time testing method is a bit suspect.
Anandtech haven't published a review of the Mini yet but in their review of the Galaxy Note 3 you can see some battery tests they did of the HTC One Mini and it holds out pretty well considering it's not a phablet.
I bought mine two weeks ago. On the first week, my battery just last 10 hours at least and after a few days of experimentation of various settings and process monitoring, I can last 24 hours with still 20% remaining.
My daily usage can be define as quite conservative as I'm busy at work most of the day.
Here's my activities to give you an idea:
Call - at least 3 minutes a day
SMS - least 20 messages a day
browsing via HSPA / 3G - at least 1 hour a day
browsing via wifi - at least 1 hour a day
playing games - at least 30 minutes a day
reading / composing / sending emails - I set this to manual, at least 5 times a day (when I'm at home)

No matter what the phone, you tend to see battery life tests showing 8+ hours of web browsing battery life. However, real life never matches up to this expectation, with 3 or 4 hours of web browsing much more typical. This is the case with all smartphones - even a device like the Note 2 or Note 3 (albeit with higher expectations to begin with: - a Note 2/3 may tests 11+ hours web browsing but typically get 4.5+ in real-life conditions).
Unfortunately this leads many to believe that their brand new device (or its battery) is faulty. But in most cases this is not true.
I'll attempt to explain the real reason for the discrepancy.
Most importantly, the battery life tests are exclusively limited to that activity or task. For example, fully charging the smartphone, continuously web browsing for 8+ hours until the phone dies. In reality when we use our phones, the phone will be on standby, or doing other tasks, at other times. For example, 8+ hours of web browsing from a full charge is not the same as getting 8+ hours of web browsing over a 16 hour day. Those other 8 hours, even if the phone are on standby, are going to use up some of your battery, too.
The single biggest battery drain of a device is usually going to be the screen, unless you have specifically forced the screen brightness to a low (<33%) amount. At full brightness, a smartphone may burn through battery after only 3.5 hours of web browsing even if it could last 8+ hours at 40% screen brightness (the brightness control is not usually linear in terms of power draw). Review sites tend to standardise on a particular brightness level that is relatively low (the reason for this is often that allows fair comparison with devices that just can't get as bright). The bottom line is that 8+ hours of screen on time at lowish brightness might drop to half that or lower if you let auto-brightness bring up the brightness during the daylight hours or when outdoors, or if you prefer higher brightnesses.
Often, battery life tests will be done over wifi with mobile phone reception disabled entirely. This is not realistic as with a smartphone you're usually connected to a cell tower even while you're using wifi, so that voice calls and texts can still come through. Also, cellular uses a lot more energy while idle than wifi does. So even if you set the brightness really low and do nothing else with the phone, you still shouldn't be surprised that you can't get 8+ hours of web browsing if you also have the phone connected to a cell tower in the background. Some sites will conduct battery life tests over the cellular network instead of wifi, and typically these will get much lower battery life ratings (eg. 4+ hours, even with the same brightness level as for the wifi test).
Bottom line is, don't head back to the shop if you only get 3 to 4 hours screen on time during the day with web browsing. This is entirely normal for *some* usage patterns. You can improve it by:
Disable auto-brightness and set the brightness to a low-ish value, say 30%-40% of maximum. This might be able to double your screen-on time compared to full brightness.
Avoid using the phone much in direct sunlight. For the brightness to be high enough to read in direct sunlight, you'll be burning through your battery quickly, and if you've set the brightness manually to a low level as advised above, you won't be able to read it in direct sunlight.
Connect to wifi (but of course, only if you trust the wifi network to be secure and respect your privacy).
Realise that if you ever play CPU- or GPU-intensive games (most casual games shouldn't fit in this category) then a beefier battery or external battery booster may be a good investment. There's not much you can do about their battery use.
Only after considering the above should you hunt through battery usage analysers and wakelock detectors. In many cases even a misbehaving wakelock that keeps your phone partially awake all day has a low impact compared to having the screen on full brightness for just 20 or 30 minutes.
