Solved Strange thing about my tablet's battery life.

[WinAndLinuxTutorials]

I have been noticing a strange thing about the battery life of my tablet. When browsing the web on it, the battery drains really fast, it dropped 2 percent in 9 minutes. What I have done is: Opened MalwareTips and browsed for 4 minutes, opened a new tab with Facebook on it for 4 minutes browsing and a new tab with a YouTube video for 1 minute. The battery drained from 79 to 77%! But when I leave it idle, with wifi on for 6 hours, It consumed just a 3 percents. I also tried to play music for almost 30 minutes and the free RAM was around 100MB and that consumed 4 percents.

Why does the battery drains very fast only when browsing the web?

Using more resources to display the web content, processing of web page and the use of WiFi/3G for transmitting data.

Just like a laptop running on batteries will last longer on idle vs running a game with high graphics settings.

Rendering. But maybe if you would turn off GPU acceleration, it wouldn't drain that much? Not sure if that would give you an enjoyable browsing either.

2% in 9 Minutes will give you around 7.5hours

How long do you think it should last ?

Sounds fine to me

Do you on GPS ? If yes you should off because it will take a lot of batteries.

You have been trying to clean the ram? some programs will run in background without tell you and use the button 'back' button than 'home' everytime you want close an application.

I do use GO Task Manager to kill all running apps in 1 click and I use the back button. I also have GPS turned off. I just tried once more watching YT videos and browsing. Battery drained from 60 to 50% in 20 minutes. Can it be because the battery is just 4000 mAh?

Battery Life

Samsung goes with their usual 4,000 mAh Lithium Ion battery here, and the tablet averaged 7 hours of use in a mix of standard endeavors: music playback with the screen off, web browsing, streaming a few YouTube videos, email, social networking and reading eBooks.

Yep sounds right to me, There's nothing wrong with your Tab.

The screen is your main drain on power but there's not much you can do about this. Keep the brightness as low as practical to help save battery life.

Some apps are constantly active in the background and will drain power all the time. A task manager can only do so much, Even if you kill the apps, they will most likely restart again and continue to run. Infact continuously killing them is just going to drain your battery life anyway, I suggest hunting down and removing misbehaving apps that do this or use an Android app called AutoStarts that allows you to disable strings that cause these apps to auto start by themselves.

Use 1 tab at a time or else you'll experience the multiple tab effect, The more tabs, the more power the device has to dish out. Same goes for Chrome/Firefox on Windows, The more tabs, the more RAM Chrome/Firefox will use.

Hope this helps

I guess the only Samsung tablet which has a 5100 mAh battery is the tab 7.7. Thanks for the info Xidus.

I have the ASUS Transformer and I agree, screen eats the battery the most, even if you drop it to half brightness you double your battery life easily

Wifi is the next most power hungry, but even with the screen on the lowest setting, power consumption is still around the same as wifi is when left on 24/7 so yea, screen is a hungry thing.

Who is the developer of the app AutoStarts?

I have found a free app with a startup manager. It is called ES Task Manager (Developer: EStrongs Inc.)
