Calling all tab owners!!!

Hey guys,
I am counting the days until the 1st November so I can purchase my Galaxy Tab.
I just have one question for you. What is the battery life like on your Tabs?
I have done a little maths and so far my results have told me that the battery life should be over double the life of a Samsung Galaxy S.
Maths:
Galaxy Tab: 4000 mah
Galaxy S: 1500 mah
Sinse the Galaxy tab has exactly the same specs as the galaxy s, the only thing I could think of that will drain the battery faster is the bigger screen on the tab.
Now lets pretend that the galaxy tab screen is 8 inches, exactly double of the galaxy s. Lets also pretend that the 8 inch screen makes the whole device consume 100% more than the Galaxy S. This means 3000 mah would make the device equivalent to a Galaxy S. That leaves 1000 extra mah!!
These figures are all over estimation so im hoping that it is double the battery life of the Galaxy s.
Are you guys getting these results?

for now im happy with mine

Mine is very good and i am a heavy user.
I can get at least 1.5 days out of it.

Seems good so far. I've been using mine heavily for last three days (typing this on it now) and it's been at about 40% battery when I go to bed and hook it up to the charger.

thanks for the info guys! sounds very good. I cant wait for november 1st!! so you guys think the battery is definatly noticebly better than the battery life of a high end android phone?

its not the best battery but better and can become more better with firmware updates
i have its since last saturday and i am getting decent 1 day battery with heavy usage

Yeah about a day on a full charge. By the way, could I have any problems from using a USB extender cable? The provided cable is pretty short.

Some days its ok, but days when I use 3G connection a lot the battery drains around 5:00 pm.
The battery life on my Galaxy-S phone is much better.
of course I use brightness on max most of the time...

Well,you can think of the issue this way: 8" diagonal vs 4" means 4 times bigger area.
With that said, you can not forget that it uses Super Crystal LCD vs SuperAMOLED
SuperAMOLED display is known as less power consuming than other, since it displays black without consuming power and works extremely hard showing white. So on black themes it is much less consuming than already bigger LCD the Tab got.
Third, the resolution itself. 1024x600 is roughly 2 times more than 800X480 which means twice as much processing power should be spent on exhibiting something on this already bigger, hungrier display.
So. If it was as simple as you think it should have last for a few hour using your equation.
P.S.
Mine is working 1.5 days with moderate usage.

it goes from 8 am to 8 pm but only barely. In fact I did run it down to 10% today. I will be buying a USB cable as soon as I can find one to plug it in in the office. I have 3G, WiFi and Bluetooh turned on all the time an run the screen at a decent brightness level though.

So basically, people with bad batter life have loads of things running (WiFi, 3G, BT) with high brightness.

Yep. Mine will last a full day from 7 am till 10pm. Using it to talk, video, browse and of course games. ..

[Q] Battery life question (before buying)

I'm considering buying Nexus 4 and after reading various reviews and user opinions my only concern is - how is the battery life?
Some are saying it's great, others are saying it's crap... See me confused.
I've got no intention of using it for watching movies or heavy gaming, but would still like it to last me at least whole day without charging (24 hrs).
Currently, my SGS2 lasts from 1,5-2 days without charging (I'm using JuiceDefender).
Can anyone comment on the subject, especially compared to SGS2?

I had a galaxy s2 before the nexus. Compared to my s2 the nexus pisses through power mainly on WiFi and surfing the web. Location services and google now use battery a lot too + overnight i loose more power compared to thr s2. I'm hoping its software related and Google improve battery in updates to JB.
I don't believe those who say the battery is great for one minute.

Pretty damn good so far for me my SGS2 would be dead in half the time, even with the screen off!

People with bad battery life are just watching porn on their phones..

Who watches porn on a small screen vs a huge monitor? :silly:
Depending on the apps you use, battery drain can be a huge downer for this phone. I use eBuddies for aim chats at work and that thing drains through, so does GChat. Navigation apps such as Google Maps or Navigon also burn battery like there's no tomorrow.
So the question of battery life really is dependent on your daily needs. The difference with other phones is that some have removable batteries.
Expect to invest in a mobile recharger, or to have spare charge cables always on hand with this phone.

I don't do much with my N4 during the day and came over from an SGS2. SGS2 by far outperforms the N4 on battery life from my experiences.

It seems the N4 has fantastic idle battery drain. I let it sit a full 7 hours over night and lost 3% battery, but it seems when you're actually using the phone, the battery is middle of the road. I'd say its still better than my S2 and as good, or slightly better than my S3. :good:

Do you think that a non-removable battery will be a problem?

I currently have a Samsung Galaxy S5, and I'm seriously thinking about upgrading to the S7 Edge...however the fact that I can't change my battery is one of the problems I'm afraid of. I'm a hardcore gamer, and after 2 years, my battery for the S5 was dying quickly, so I had to change it. I started using the phone almost all day to play Marvel Future Fight towards the past 6 months and that is what really messed up my battery I think. So I'm wondering if I upgrade...if the phone will last 2 or so years? Cause I ain't got the money to be upgrading every 6 months or every year lol.
What are your thoughts?

Even tho it doesn't has a removable battery like your s5, you can still have the battery replaced by Samsung. Downside is that you can't carry an extra battery with you in case you run out of battery during the day.

So I came from the LG V10 with free extra battery promo. I went through 2-3 full charges a day. I've been on this battery since 8am today. It's 5:49pm and I'm at 54%!
Oops sorry... Just realized you're more worried about the battery's ability to hold charge down the road.
Haven't owned a phone more than 6 months so I'm not sure lol. You could always get one of the charging cases later on when prices drop.

Lol yeah the battery lasting long sounds amazing, but after 6 months of gaming every day, I'm sure it will take a toll The charging cases sound like a pretty good idea though.

It does costs more than getting an extra battery for your s5, but you won't have to pay for a new phone every 1-2 years. Nowadays most phones have non-removable batteries, except for the Lg G5, but it has a 2800 mAh battery when the s7 edge has a 3600 mAh.

it's not an issue in the sense that no one keeps a phone 4 years nowadays. For instance, using a QC 2.0 adaptor shortens the battery life, however over 1 or 2 years, it is barely noticeable. It is noticeable only if you keep your phone for years and years. But most people change every year.
These batteries are good, they're not super cheap, so it will be ok. Samsung replaces the battery only if it's really defective, not if you lost like 5-10% of the battery charge.

I have two bloated S5 batteries first lasted 18 months and second lasted 6 months which was last week. I was a very heavy user and my phones over heat. My old HTC EVO had to be in the freezer a lot and had 5-6 batteries. But I believe a with normal use the battery should last 24 months. I have been thinking of putting phone on discharge timer to plug in and unplug.

I've never had an issue with my S6 Edge that I'm trading in for the S7 Edge.

True that, but would they just replace your battery or the whole phone itself? Like would I have to back up my data?

That's very true, and I had no idea that QC 2.0 shortens battery life, does QC 3.0 do that? I know we'll be getting that with the wireless charging. Regarding replacing the battery, what do you mean by "really defective"? What do they consider defective? I find that loosing 5-10% battery charge in less than an hour really defective lol.

Damn, well I'm barley on my second battery after almost 2 years lol. My S5 overheats a lot now and sometimes I don't use it much. It lags a lot and sometimes messages don't send..so I really need a new phone. :/ How do you put the phone on a "discharge timer"? I'm thinking of not leaving my phone overnight charging cause that's how the battery messes up more I heard. I probably also won't play games while charging my phone either cause that'll kill the battery's longevity more than usual.

They will replace just the battery, for the s7/s7 edge they use heat to open the back cover and they replace the battery. On the s6 they also had to remove the screen in order to get access to the battery (you can watch videos of how they do it).
From a quick search online, it costs $45 + shipping to replace the battery on the s6 in the US, I could be wrong as I have no personal experience.

I know we're talking about different device's but my z ultra (heavily used) and Z3CT both still rock battery like the day I bought them. Hence why I'm not worried to much. Don't let it put you off a device also you could always change battery after a while just a little bit harder to do lol.

My previous phone was the S5 and I wasn't to happy about going to a phone that doesn't have a removable battery seeing as all my phones had a removable battery. That is one reason why I went with the S7 Edge so I wouldn't have to worry about the battery as much.
With my S5 and before that my S3 I would just keep the phone plugged up if I was playing a game that used a lot of battery.
Get the S7 you'll like it.

Nice, I just hope the S7 is the same way lol. Sure, we can always change the battery after awhile and it'll be harder to do, but it'll be more expensive than just buying a battery outright like someone said earlier in this post But...it'll be worth it lol.

Yeah, that's exactly how I feel lol. I've been doing that with the S5 and before that the S3 and I really do feel like it kills the battery's life more while leaving it plugged in while playing a game. :/ But I already pre-ordered the phone today from T-Mobile so I should have it in 3 days or less

I use s7 edge since release day. Battery detwriorated so much?

Hello people. I use s7 edge ezynos version from the day of release. Dor half a year my battery life became much worth. Tryed everything, reflashing resetting etc etc. Then I've found accubattery. After several charges it gives me information that my battery has 69% of actual capacity 2480 mah from 3600 Should I trust that? Is it normal for battery to detwriorate this much? I vharged it once a day max. At the beginning once in two days or so :/ My much older oneplus one gives 79% of battery capacity and it is the one that was abused by charging twice a day and with heavy gaming etc. Please report your battery states and please give me advice. Should I change batteey on galaxy or should I just leave it like that Is it worth it to give it a new original battery? I am sure water resistance will be gone..

Most of the damage on battery on Samsung devices are caused by fast charging.
And it depends on you is it worth replacing or not, if you think that it lasts for you enough then don't replace it.

Damn. Maybe I will sell it cheap and buy s9 or something..

battery is easy to replace.
battery life is about 1000, so in 2 years it is possible

I never use fast charge as in my opinion it makes the battery cells work faster than they should which damages the battery quicker,the s7 edge charges fast enough anyway without fast charge on

Is It Worth For Upgrading S8 to S9+ Since My Battery Health was 88%?

Hi.
I am a s8 user with stock rom, no root for 1,5 years. My battery health (samsung info app) is 88% with ~560 charging cycles.
samsung ceo has been guarenteed that it wont be less than 95% in 2 years but it did.src
So my SOT is 3-4 hours with even lots of things disabled, blocked, sabs etc.
Is it worth for upgrading to S9+ for fixing my battery issue, dual and better cameras, dual speakers and one ui?

Only you can answer that I can tell you that I personally am waiting for the 10
The question is.Is it worth it to you to upgrade?:good::good::good:

My S8+ charge 780+ cycle, the software AccuBattery detects the charge is only 3000mah, but I used the volume meter to detect the discharge after replacing the battery, and there is 3300mah, so the battery is still very strong.
