Thank you all. I will try a factory reset then. My battery status now is 65% with 2hours 28 min screen on with only surfing web :-(

Anyone has factory test service running in background?

Sent from my GT-P6810
[Galaxy Tab 7.7 General] geogetski666:
i think you may have an app thats running in the backfround that doesnt exit even when not in use had the same problem before with my old p1000 i thought i had a lemon unit but the culprit was the a certain app forgot the name it was about a year ago :) you may want to use the samsung task manager and see if any app is running in the background or use a task manager on the market :)
[Galaxy Tab 7.7 General] ThE_SoUrCe:
and just to add, do turn off the background data on the settings, it's another power hog
[Galaxy Tab 7.7 General] Theory:
I find it hard to believe that the iPad 2 can go for 17 hours of usage. Engadget's battery test says that their 7.7 lasted about 12 hours, 1.5 hours more than their iPad 2 (looping video, wifi on, screen at 50%, I seem to recall).

Also see settings> about device> battery use to see what's eating the charge. Normally, the lion's share goes to the screen. But games can use significant amount of charge too.

I've been able to about 10 hours of continuous usage (light browsing, email, xda, kindle, pdf reading on either repligo or mantano).
[Galaxy Tab 7.7 General] yucww210:
That's what i think too .
[Galaxy Tab 7.7 General] EarlZ:
For video playback the Tab7.7 will have a longer battery life since it is using GPU decoding as compared to the Ipad2's SW only. But when it comes to surfing and everything else, generally for anything else apple devices can outlast samsung devices or andriod.
[Galaxy Tab 7.7 General] Theory:
According to battery widget pro estimates, if I stick to reading on the kindle app, as I have been doing for the last couple of hours, I will be able to last another 18+ hours. Wifi is on, screen about 15%, background auto sync on. (Since it's a longish Neal Stephenson that I'm reading, I'm going to need that much time.)

Incidentally, I found battery widget pro very useful. Have it on each of my Android devices.
[Galaxy Tab 7.7 General] a_hadada:
Aaawww, I feel so bummed to post this, cause I am otherwise absolutely in love with my galaxy tab 7.7, but I feel a bit iffy about the battery life aswell. I switched to galaxy tab from Asus Transformer TF101 and I actually feel like the battery on my previous tablet lasted waaaaaay more, even with the wifi switched on permanently. On my Galaxy Tab 7.7 3g I can easily lose 20% of battery power during a half an hour of browsing the internet on low brightness, with wifi, gps, bluetooth and background sync switched off...that is hardly the "phenomenal battery performance" mentioned in all those reviews. I use ADW launcher, not so many widgets, I dont even play music, games or video and still the battery will not last through the day at all...I mean..I only would use it for reading an ebook, browsing the web and facebooking 1 hour on a bus in a morning and another hour in the evening....but no chance...the battery wont last that long. It would exhaust the first 40% on my way to work, and come down to 30% during the day (when used very rarely). I can easily last the whole afternoon with switching the battery saver ON every time I am not using the tablet, but to resort to that, and to switch everything off and lowering the brighteness to miminum just to be able to browse internet for an hour and lose almost 50% of battery power by doing so, feels really desperate. I still dont want to believe I am the unlucky one to get a bad unit with a dogdy battery...what should I do to make sure tis not the case? Is there a test I can run to see for sure if I have the battery which drains the same way as the others or not??? Thanks in advance for any suggestions.
[Galaxy Tab 7.7 General] zoftdev:
i personally have no battery problem with surfing internet . because i have use customized css in opera mobile, every page become black with white text.
[Galaxy Tab 7.7 General] a_hadada:
Ok thanks, but that does not really help..I just wanted to know if there is a way of knowing for sure (e.g. by running a certain test or something) that my battery is officialy flawed compared to the others in these units. All the reviews for this tablet mentioned an exceptional battery life and yet I am loosing almost 10% every 10 minutes of browsing (not playing video or music, so not a heavy use really) on the minimum brightness, with gps, wifi, bluetooth, background sync, vibrations, animations switched off...does not seem ok to me.:confused:
[Galaxy Tab 7.7 General] Theory:
Install a battery monitoring app (e.g., Battery Monitor Widget Pro) so that you can track/log usage.

No, your numbers don't seem right.
[Galaxy Tab 7.7 General] earthman5678:
Check what been taking up all the juices in setting-about-battery usage. I had similar problem previously when my exchange push mail was not working correctly and keep connecting to sever. Did a hard reset, everything is back top normal.
[Galaxy Tab 7.7 General] EarlZ:
I dont have any battery life complaints yet as TBH, i dont really know what to expect from a 7.7 Inch screen with 5100mAH of battery, suffice to say that it out lasts an Ipad2 on anything but web browsing is already good enough for me.
[Galaxy Tab 7.7 General] Richdog:
My battery is very good, light years aheadof the Blackberry Suckbook that it replaced. I generally get a full day of heavy use with Wifi and 3g browsing, and two days of "normal" use. :)
[Galaxy Tab 7.7 General] geogetski666:
if your tab is rooted and you know the system files you may want to install nobloat and remove system apps that you don't use :) tried it and lowered my actual ram use to 400 to 500+ and keeps my tab snappy :) be warned make backup before using :) just to be sure :)

and another thing always try to clear memory using task manager when your gonna let it standy i found it to use less battery than when many apps is running in the background when on standby :) hope that helps :)

So is the no microsd support becoming a new trend now? Started with Google Nexus followed by Sony's Xperia S and now HTC Endeavor. I understand the advantage of not needing microsd, that you can just plug your phone to the pc and then still able to play music (or whatever apps) through your phone uninterrupted, but there are still people who find the fix capacity a little...hard to deal with.
[General Topics] boomboomer:
I thought the internal sd card was originally to comply with windows mobile specification, then manufacturers used the same hardware for other models e.g. sensation XL is the Titan, just with Android instead of wm7. I'm not sure this will result in a new trend, but being unable to eject the card, also having a known specification of card probably reduces problems to the OS.

Not sure the larger displays on the new crop of phones are an improvement, with only a 1800mAh battery the reviews will probably ***** hardest about the short battery life.
[General Topics] thelegendarylegends:
the 1800mAH is gonna die!! click thx if ur agree with me!!
[General Topics] Sibbi:
This craving for "Thanks"-Hits lately is really annoying, to say the least. (Not directly in your direction, but in general).

Back on topic:

I´m not that fond of this trend, but it seems it is going that way.

My only concern about this, is the fact that it is getting more difficult to, let´s say, flash a firmware, that won´t boot up with your current rom etc.

Other then that, I don´t see that much of an disadvantage.
[General Topics] thelegendarylegends:
Mate don't get me wrong, I never crave for thx, I was saying ppl will obviously agree the 1800mAH batt will be killed by tegra 3 quad core that's all.

It´s allright. I see your point and agree with it. But still I find it annoying, that there are lately a lot of people trying everything to get a few more hits.

[General Topics] dgenx210:
Well Tegra 3 does have that low power and low clocked 5th core ("companion core") for standby so that should extend the battery life a bit.

[General Topics] moshe22:
The no micro sd thing doesn't bother me at all. As long as I can connect it to pc and manage my files, I'm cool with that.
[General Topics] thelegendarylegends:
And as long as the internal is more or equal to 32gb, because ill feel cheated, when other phones can be used with with bigger sd cards
[General Topics] townay:
I dont know if most future high end phones might endup with a fixed storage capacity, but if that is the case, maybe I might have to get a mid end phone for my multimedia needs. Dont know if it will make flashing more difficult but I do know this, if companies release a 16gb first followed by a 32gb a couple of months later, I will likely rage. At least with a removable microsd, I have nothing to rage about..(unless one of them somehow gets corrupted)

Personally I keep another 32gb microsd filled with chinese dramas in my wallet.
[General Topics] abstractsimon:
Not sure it bothers me too much the no SD card slot thing, would rather it all be inbuilt than have problems like the Cha Cha has constantly running out of internal/inbuilt storage... I suppose the only thing I'd miss is the re-assurance that if my phone completely died I could still get my files and photos out of the phone without any trouble...
[General Topics] taxus13:
But it would be better to use 32GB internal and 32GB external storage :D

I hope you can access the storage via MSC, MTP sucks if you are on Linux or any other system that uses MSC (eg radios etc.)
[General Topics] k0zmic:
This. Battery life should theoretically be better.
[General Topics] mrbkkt1:
The reason...is economics.

When memory was a lot more expensive, it was more cost effective to let the consumer pay for large sums of memory.remember when 16 gig micro sd Coss cost 100 bucks?

Blame Apple who were charging An extra 100 bucks for an extra 8 gigs. Pure profit for phone makers now that memory its so cheap now.
[General Topics] cihanleanne:
only in theory. most power consumption its the screen i think 4.7" 720 p will use at least %50 more than sensation. so this is what we all find annoying todays phone. Only motorola has tried to give, bigger battery 3300 mah which i think its awesome! Htc should sell their flagship with bigger battery.no micro sd i dont think its any problem, most of people using 8 gig sd card so if phone 16 or even 32 whats the deal.
[General Topics] Ouzo:
No micro sd card slot is a disaster for me. My music collection is over 40gb, games are often up to a gb each, my European maps are about 2gb and I like to have a few films or tv shows on board to kill time too. With a more powerful phone I'm going to want have hi-def films on board so I can stream to my tv (or to a friend's tv). I also have loads of photos from holidays and stuff which I like to keep on my memory card. Not only do I want a micro sd card slot, I want new devices to support micro sdxc for MUCH greater storage capacities and faster transfer speeds.

The cloud has its place for me, but I don't want to be left looking like a chump when I can't access a photo or song because there is either a slow or non-existent data connection. What about when my phone has to be on flight mode? Why would I want to eat into my data allowance to stream a song that could so easily be on a memory card? Streaming stuff to my phone uses noticeably more battery too.

Manufacturers want us to have fixed storage so we have to upgrade our handsets as our storage needs grow. They also realise that people are prepared to splash the cash on larger memory cards so they figure they would rather put that memory in the phone and take the extra money from us instead of letting that cash go to a card manufacturer. Finally, networks want us to store our stuff in the cloud because sooner or later we will go over our data allowances and they will make a killing in extra charges.....the next time we get a contract we'll all go for more expensive plans with a better allowance. They're not worried about the unnecessary data slowing down our mobile networks because they'll just throttle connection speeds accordingly.

Choice is good. 'Light' users won't mind a lack of SD card slot, but those of us who truly use our devices for media storage, communication, photography, sat nav and increasingly as a dockable pc replacement are really gutted. Windows mobile used to be able to connect in two ways, so there's no reason why our current devices can't pull the same trick.

dang, sd cards are so useful
[General Topics] pimppoet:
Yea for some but even feature phones have them. With the use of memory cards & tech as a whole becoming more mainstream in gps units,car stereos,tvs,etc people are understanding more or atleast have afew "nerds" in the family to explain it to them. Ive dealt with my share of lazy,confused,& nontechy customers so I understand your point of view on the user experience but that still no excuse leave out the feature. If the rep is just about the sale & the customer in unwilling to learn it doesnt matter what item your selling.

I think the nonremoval memory/battery idea works so well for apple because they take care of the issues directly bypassing carriers sometimes ****ty cs. Plus u cant complain about what you never had.

Far as the cloud its not a almighty fix due to coverage,data limits,privacy/security concerns,& overall reliability.

[General Topics] charmthief88:
There is a lot to love about the padfone like how charges your phone while in the tablet.

You've also made a wonderful point about the usefulness of the krait processor being a very capable processor in previous threads.

I don't mind thin phones but not at the expense of three critical factors. Decent battery size, micro SD expansion, and durability. I still hold the Razr Maxx in high esteem, and look forward to the Panasonic Eluga power (no removable battery though but waterproof) Fujitsu F12arc. Plus Moto rumours of upcoming phones Atrix 3 and Droid Fighter both say micro SD and large battery.
[General Topics] adone.h:
For me this is a great problem as I usually work with non-original rom that sometimes freeze the OS and the only solution with my htc hd2 is to eject the battery.
[General Topics] Aitcheff:
On the HTC ONE X, holding down the power button should in theory have the same effect as pulling the battery. I hope I never have to test this in earnest!
[General Topics] eletro:
I hate how the market trend trying to copy apple design blindly without thinking.

One perfect example is this: asymmetric earphones

Its soo hard to find good asymmetric earphones nowadays.. everyone is copying apple's symmetric earphones.

Having asymmetric earphones means the earphones will still hung around your neck while u take off it.

Copy no sd on apple..

On apple, all application is seperate sandboxes that works by itself, make sense to have a unified storage for that solution. However on android, whereby every app can share a pool of data, it makes sense to have expandable storage!

No expandable battery..

Apple OS is designed to conserve battery, all application using the same notification api, single pipeline design.. thus having no expandable batt make sense and simplify the design, no matter how many application you install.. the drain is relatively same.

Each application in android mainly run by itself and spawn their own respective connection and sleep cycle.. and generally consume more battery as more apps are installed.. thus having expandable battery is better!

Instead of blindly copying.. one should build upon their OS strength.

a phone without any expandable memory slot just makes me feel tied down and I don't like that feeling.
[General Topics] rustyguy:
Even BB's have expandable storage. Honestly the cloud is cool, but for my music/video needs its just not realistic to stream **** all the time and expect my phone will last a day on battery or that my data account will last the month.(1 gig)

Phone companies should also notice that I would gladly carry a device that is a few mm thicker with a better battery. When you hold these 4.5" displays your not going to actually notice 2 or 3 mm in thickness, may even feel better.

[General Topics] nexxer:
No SD = no buy for me too, and in fact I won't even suggest them to friends who ask about them, if they're atleast semi-power users.

Good example is the Nexus S, that even in its current low price I am telling a friend to stay away from, knowing he'll run out of space very quickly. Coming from an older phone he doesn't believe it's a priority, but getting a quick android is like getting fast internet for the first time.. you'll fill it up :)
[General Topics] adelmundo:
To me, I think the reason why the manufacturers are doing it, both non-removable batteries and no SD card slot like Apple is so they can easily make more money by cutting out 3rd parties who sell SD cards and aftermarket batteries. Just like Apple, they can sell the same phone with different storage options for more money and it will also force the owner to replace the phone as the battery gets worn down and holds less of a charge, or replace the battery for a significant cost.

What really made me buy an android over the iphone was the ability to increase storage via microsd. i could have 8gb on my phone then pop in 32gb so i can have 40gb.

So I'll assume that samsung's galaxy nexus wasn't made by samsung...

I'm not a big fan of unibody stuff, but having removable parts with little hinges, like smartphones, makes them prone to break easily.
[General Topics] charmthief88:
Cute point, it was a mistake to pin it all HTC. However I've contended a few times that Samsung intentionally dulls down the Nexus device, so it won't totally outshine its own chosen flagship.

The lack of a removable battery is a dealbreaker for me. Batteries are prone to lose capacity over time - it sucks to have to get rid of a $400 dollar phone because you can't replace a $5 battery.

MicroSD, not so much. My entire music collection is only 2 gigs, and that and a few episodes of Community are the only bulky items on my phone. I'd be curious to know what the people who need more storage are filling it up with.
[General Topics] dlmx:
I would have to agree I will not buy a phone if it does not have a micro sd slot. I am trying to wrap my head around the idea of not having one but having a hard time with it.

Seems to me the micro sd is essential to Android.

Just my thought.
[General Topics] MR4Y:
My music collection is about 8gb and still growing... Internal memory only will not suffice for me as well. Maybe they should consider phones that aren't this much slimmer so they can accommodate a sd card slot as well as bigger batteries? I dunno.

You can also add non removable batteries to that list. Granted my Touchpad doesn't have an microSD slot or a removable battery but it was discounted so heavily that I made an exception.

But I'd say microSD sot is more important that a removable battery IMO. Mostly because a battery is tied to that device model where as a microSD card is universal. So if I decide to invest in a 64GB card I know I can use it on future devices.

[General Topics] anjin75:
I like the possibility to swap battery. And more the sd slot. It's more that a simple storage thing. Really I'd like to have TWO card slots, better if one able to hot swap. In normal use it's not so important but there are situations were it is. Travelling for example, use the phone like your own computer device, with two slots you can use the device to backup the photos of your camera. You can use also the device with the primary card with yout standard things ,and have the other cards for movies, music and more things or backup. I mean, when you are out and far from home, travelling without internet, everything makes your device more usefull is welcome. Especially if you are trying to use it instead to have a heavy laptop with you. Naturally I'd like to have usb otg, better if with 5V output. Bad thing there is only a usb for charging and communicate. I'd really like to have two separate usb, both for charge or usb bus. Yes, I know, I want strange things. I really don't mind a heavy phone, I like more possibilities and battery power.
[General Topics] MR4Y:
Problem is that all people care is faster and slimmer. We're generally accepting that faster devices must have a battery that lasts less. I would prefer much more a device that wasn't that slim, but had a decent battery life and removable storage.
