RAM doesn't have any affect on your battery life. The more demanding components like CPU and GPU will though. Restarting apps frequently will increase load in CPU which in turn increases battery consumption.
Increasing the amount of RAM in a smartphone can decrease its battery life, as more RAM requires more power to operate. More RAM always draws more power.
6 and 8 GB models are all in all the same, the only real reason to look at spending extra for the 8GB one is that extra storage. More RAM will have very little impact on the phones performance. Of course, 8GB of RAM is better for more multitasking but frankly you'd be hard pressed to spot the difference.
3. Check Your Ram. Did you know that your RAM size can also affect your battery life? More RAM means your computer can perform processes faster, and your hard drive won't be as stressed, increasing your battery life.
Based on the results, our recommendation is to aim for a minimum of 6GB of RAM when buying a budget smartphone. For upper-mid-range or high-end devices, 8GB will provide a good multitasking experience plus some future-proofing.
**Mid: mid games, multitasking, youtube, navigation and in general more difficult apps. ***Heavy user: heavy games, video/photo, video rendering, heavy multitasking, lots off apps opened in the background, etc. 8GB should be fine. The problem will be more of Android updates more than anything else.
It just doesn't , and that's especially true for mobile-optimized lpddr dram like what you'd fine in a phone. Even in a desktop computer , DRAM power consumption is typically under 10W . In a phone , the power used by that extra ram will be dwarfed when compared to what the screen or SoC uses.
A more technically correct way to phrase the answer would be something like, Each memory module uses a mostly fixed amount of power . If you have 24GB of memory on your machine it will at all times use more power than an otherwise identical machine with only 8GB of memory.
RAM Power Consumption
The main reason why DDR3 RAM consumes less power than DDR2 or DDR RAM is due to its lower operating voltage. A higher clock speed will also lead to higher power consumption (e.g. DDR3 RAM running at 2,133 MHz will use more power than DDR3 RAM at 1,600 MHz).
No, it does not. RAM always consumes some fix level power the battery when the laptop is turned on no matter RAM is full or not. However, the battery will be drained if the CPU is in high loading.
How much RAM do you need? Generally, we recommend 8GB of RAM for casual computer usage and internet browsing, 16GB for spreadsheets and other office programs, and at least 32GB for gamers and multimedia creators. How you use your computer influences how much RAM you need, so use this as a guideline.
One of the most common questions we get asked is “how do I know if my computer needs more memory?” The answer is actually pretty simple. If you're using a PC that was released in the last five years or so, chances are it comes with 8GB of RAM – which is more than enough for most people.
A 6GB RAM phone should be plenty for most people, although if you tend to run lots of apps at once or like to play high-end games, you may want a model with 8GB or even 12GB of RAM.
As a rule of thumb, however, you want to allocate around 3 watts of power for every 8GB of DDR3 or DDR4 memory.
To be honest, there's not a lot of difference between 8GB and 16 GB of RAM. If you're doing office work and more basic games, then you really won't notice a massive difference between the two. However, if you're wanting to do video editing, play the very latest high-end games you'll definitely need more…
Advantages of Static RAM
SRAM has a low power consumption compared to DRAM. SRAM is used for creating speed sensitive cache. SRAM does not need to refresh the memory contents.
The speed of RAM is the rate at which the memory can move data and, for specific tasks, can be more important than the size of memory. When determining how much RAM you will need, remember to consider the tasks you will perform.
DDR4 is more efficient that DDR3, consuming up to 40% less power and requiring only 1.2V per module.
No, it does not. RAM always consumes some fix level power the battery when the laptop is turned on no matter RAM is full or not. However, the battery will be drained if the CPU is in high loading. The performance of the CPU depends on how many program is running.
As a rule of thumb, however, you want to allocate around 3 watts of power for every 8GB of DDR3 or DDR4 memory. High-performance memory such as Ballistix® parts can draw more power, especially if you overclock the voltage beyond XMP settings.
Leave something that auto-refreshes open in a browser window, like sports scores. And if your computer is equipped with Bluetooth, turn that function on, too. Open up a few other applications to run in the background. Running several apps at once is sure to kill your battery quickly.
Anything with more than 6GB RAM should suffice, though if you're buying a smartphone for gaming or other intensive operations, you might consider an 8GB model.
This means that the more there is in your phone, it'll be able to handle more apps and the data in the background—this will enable much faster switching between apps, and the ability to open and leave more pieces of software running. The other advantage of having a lot of RAM in the phone is future-proofing.
8GB RAM: 8GB is the best balance between cost and performance. Power users who want to use video editing applications or have many different apps and games to switch between should go for 8GB of RAM, since it's perfect for heavy multitasking that results in high RAM usage.
