Hi,
I was wondering how was the battery of the Microsoft Surface Pro? I currently have the Surface RT which I find really amazing but I have an occasion to switch to Pro, should I ? The only thing that keep me against switching is the battery life.
So..
- How long can a Microsoft Surface Pro stay in sleep mode before the battery gets empty?
- How long can it handle the screen ON at 'Auto Brightness'
- How long can you use the device with normal use ? (Browsing, Facebook, etc..)
- How long can you play basic game (ie Chess, Minesweeper, etc..)
- How long can you play hard game (ie Fruit Ninja, Angry Bird, Call of Duty)
Huge thanks for those who will answer and please no lie, I want the real time
3-6 hours of use dependant on scenario.
What you use it for and what others use it for will be different so any answers you get should only be taken as a ball park, same with phone batteries, the number of users I've seen over the years say they can only get half a day of use vs others that charge every other day..
The battery is poor at best... I hope they implement the 'new' battery into our tech soon.
Alright and how long can it stay on in sleep ?
If I use a power saving profile with low brightness and CPU throttled to 50%, I can get between 5 and 6 hours if just using Word, Excel and web. That is with a BT mouse and Type cover.
If I don't throttle the CPU and use the pen a lot (eg. marking up a pdf, using one note, or using the pen instead of a mouse in tablet mode), then the battery can last less than 3 hours. The pen seems to use a lot more power than just typing or using capacitive touch.

Hmm weird that the pen seems to take a lot of battery, the best would be that you compare with the test with the CPU locked Probably gonna exchange my RT by tomorow or so
The pen uses more power regardless of the power setting.
I also notice that it gets hotter if using the pen a lot, than if not using the pen.
It seems that the pen requires more cpu power than just using a BT mouse, hence the higher heat and power drain.
Battery life is just like any other ultrabook with a 42Whr battery. When I disable Turbo and use 'Power Saver' profile for less a less aggressive SpeedStep, under my usual mixed Internet browsing, penning OneNote, and annotating PDFs I get 5-5.5hrs of usage.
Use it like an ultrabook, treat it like an ultrabook. The content consuming tablet side of it is just a nice bonus. It received it's "Pro" moniker for a good reason, not for you to d*ck around wasting time. You want to do that? Go pick up a Surface RT, Android tablet instead.

I have the Microsoft Surface RT, I'm thinking to return it for the pro
Hi sleep mode lasts at least 10 hours. Probably much longer though as I have not been able to leave it alone longer than that. But if I have a full charge and set it alone over night. I wake up with almost a full charge (8 to 10 hours)
Oh, it'll last many times 10 hours. Sleep mode on laptops from 2000 - machines that got 2.5 hours on battery if you were lucky - could frequently hit a week if fully charged. My Core i7 work laptop (5 hours battery life in typical usage) will lose less than 10% of its battery life / day of sleep mode. Surface Pro has a smaller battery, but may also use more efficient RAM modules/connections (keeping RAM alive is pretty much the only significant drain for a sleeping PC) and should still last at least a week.
Thanks for all the replies ! I finally switched Let's see how it goes

anyway i can increase the samsung galaxy tab plus 7 to perhaps 8hrs to maybe 10 or 11? i see my ram is using more than half and i dont feel like waiting around for a rom to be developed because i cant find any out there yet!
If you are on the older KL1 firmware you can give Garyd kernel a try since you can under volt the tablet to conserve battery.
underclock
You can try underclocking. There are several apps in the market (you have to be root). Also, check if there are consuming too much processor time. For example: I've found that Dolphin uses more processor than the stock application (you can hold your finger on the home icon to quickly check the apps running and their use of memory and processor).
7~8 hours? Lol. Dude, don't expect too much. Samsung didn't change much from Galaxy Tab 7.0.
I was using N-mode Wifi, 3 tabs browsing internet 2 hours, and remain battery was 49%. It may not start at 100%, but I am sure it started at least 95% battery. C'mon, Samsung. I just did 2 hours internet with 3 tabs, and remain was 49%???
I was a user of GT 7.0 as well. It gave me at least 6~7 hours. But, GTP not.
I dunno about that. I'm taking a break from studying and noticed I'm only at 40%. Ive been Switching between pdf's and four tabs in the stock browser (which is in desktop viewing mode too) off and on throughout out the day.
Ive had this thing unplugged for 13 hours so far today, but have been aggressively using it for about four hours total. For as small as this thing is I think it does a damn good job.

Same here. I don't live on my pad but I use it for note taking at work, skittles research, and some recreation and it gets me through work at les than half used. No complaints.
really bad battery life
I have a wifi version p6210. I only get 5.5 hour max. usually 5 hours. No problem with standby, drains little battery.
I use my GT7+ for browsing most of the time - mostly forums such as xda, read news watch short flash news clips. Nothing intensive, no desktop widgets. I use Dolphin HD browser. I have garyd9's CWM + root (NOT his kernel). I have CPU Master and it says the cpu runs in ondemand mode.
I tried the auto screen brightness, calibrate battery stat etc. they make no difference. I also ran youtube video in the browser continuously and it still drains the battery in about 5 hours, same as less intensive browsing.
My original 7 inch GT can easily make 7.5 hour.
I used PropModder (also tried with Blade Buddy) to change the wifi scan interval. It's set to something ridiculous like 30 seconds, but to complete a full scan especially if there's a lot of APs in the area takes 20. So it ends up always scanning. Mine's set to 150 seconds now.
Make sure you turn of GPS when you don't need it, and turn down screen brightness. I just did a long haul standby test and (with wifi off) got almost 13 days of standby time. 100% to 10%
I get exceptional battery life out of my wifi tab. I turn auto-brightness off and adjust that manually, turn auto-rotate off when I am reading, turn wifi off when not near a network and this thing doesn't ever need to charge during the day.
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.
So i searched on here to see what the battery life is like, most people are claiming 6 to 8 hours. I'm wondering what the battery life is like when used as an ereader. I know it wont replace my Kindle but whats the battery life like if say, I'm reading books, or comics on it? I guess worse case scenario I could always buy one of those external battery chargers for those long trips home.
This is regarding the 7" tablet by the way.
Well, I didn't get any feedback but, I'll buy picking one up regardless. I'll let you guys know what kind of battery life I get on this thing with just plain reading.
I have the 10.1, but I found that battery life can vary wildly. Turn the screen brightness up to max and play a game, and you'd get 3 hours max. But if you take brightness to 1/4 and read a web page, you should get at least 5 hrs.

On my 7" Tab 2 and mostly reading during the day, I could probably easily go 2 days between charges. My problem is the other stuff that I do between reading. Still even with that, I go a full day on one charge with no problem.
It really depends on your brightness and what's being displayed. I use fbreader and use dark mode. I can go days without recharging and usually hit about 5 h and 30 min on screen time. But that's with all my different use of videos, Chrome, games, etc. I would suppose that as a eBook reader and using power saving mode will net you a higher battery result.

One of the many advantages of "aftermarket" ROMs is that with modified kernel you get a good control over the performance. Besides being able to play with screen brightness, you can reduce the maximum CPU speed as well as adjust the CPU governor, and in some roms even lower the voltage. With this much control I can get very long battery life for low resource need activities like reading. I have many times used my Tab 2 7" between the US and Asia for 18-20 hours (actual flight time plus layover) with 1 single charge and arrived with 20-30% left in the battery.
You're probably going to get more battery time than you can stand to read straight through in one sitting. If you want to maximize it, use white fonts on a black background and turn off all radios (3g and or WiFi).

I use the lower brightness, about 30%, and the battery should last for 6-7 hrs screen on.
I use my tab mostly for browsing with wifi on.

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 canĀ“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..

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)

Hope this can help somebody to have an idea.
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.
