How about that? How much sdcard consume actually?
Nexus S dont have it, there must be a reason for removing it.
SD cards require ca. 0.15 mA in "standby" or up to nearly 50mA while reading. Therefore, depending on the usage rate of your SD card, it may save power of course to not use one. Instead the data must be read from some other place like internal flash memory. As long as that consumes fewer power, it may be worth a try.
I had this peculiar experience. After reformating my SD CARD I gained 6 hrs of battery life approx now. Previous to the format it was 20 hrs max and now its around 26 hrs. May be the filesystem itself has something to do with power drain I think.
I think I will remove sdcard. My defy now has over 1GB free space and that is enough for everything

So how do you compress your 15gb music library into that single GB ?
ill keep my SD card in cheers, removing it cant use any more juice than the internal memory.
My mp3 player, a cowom d2 has internal memory and an sd slot. On sd the play back is way shorter.

On my Sansa Clip+ it makes sod all difference.
Don't use SD card, don't use 3g, keep display low, don't play games, finally sell that phone and be happy.
What would be the point in having it.

What's the point of having a smart phone if you don't use its features. Besides wouldn't it consume more time and power if you turn off your device , insert sd card (by some event you need it), turn it on again. ??? Then again, its up to you.
Got a Headache? It's all in your Head.
It does chow battery, thats why I keep most of my apps on the internal flash....and those apps you only open once in a while I leave on my sd, and movies, mp3s etc etc.
You wont need to remove the sd, just unmount it under storage, then it will not even be in standby and save some battery

This argument is not valid in my opinion. Analysing what consumes battery to a more or lesser extent is irrespective of what you use. Once you identified the power hogs, you can alter your use, or accept the consequences for the ones you want to use. If you use a dedicated MP3 player for instance, I could imagine that the internal memory would be sufficient.
For me, 3G is avoided as much as possible. Using wifi instead uses less battery.

Thanks man, i did not think of just unmount lol
I could not remove it, my navigation files must be on it... too bad because i dont have need for sdcard since i dont have lots of mp3s and pics. I have now more then 1gb of free space on phone...
Hi!
My company is working on a NFC reader built in a microSD card. Working really good so far. But there is one problem: most phones turn off the power of the SD slot in idle, which in this case cuts power of the reader.
I need to keep the SD slot powered always (for testing purposes).
Based on CM10
So I think i have to mod
Code:
kernel / samsung / aries / drivers / mmc / core / core.c
But before inventing the wheel all over again, I thought I'd ask some kernel devs, I'm sure it's like 1 minute for you to tell me how to do this
Thanks in advance.
Wow, NFC reader build in microSD card, sound good!
the sd card idle function was introduced in the cm7 era... before this, the sd card would stay on permanently, draining the battery in 6 to 7 hours.
sd card idle is very useful, for battery savings, but not for your sd card nfc card.
i looked for the commit, so you could try and revert it, but couldn`t find it.
search here, it should be somewhere around here : https://github.com/CyanogenMod/android_device_samsung_aries-common/commits/gb-release-7.2?page=1
Hello, I have Galaxy W and it keeps giving me SD card is full, memory full even I have Available total space as 564 MB and around 1.4 GB in total space and external SD card is empty. So what do you think guys where is my problem? It shows around 50 times a day and I can't download a song or take a picture, and I deleted all the music and pictures from the phone but nothing changes.. Check it out this is a screenshot. Any help is appreciated.
As my phone is really show (at least 5 seconds for image to display after I press the Camera icon), I tried to measure speed of internal storage via AndroBench application. Just download that app from Play and run the Micro test. My result on Random Write test was only about 0.5 MB/s. I guess this is really too low. I tried LagFix Free app to TRIM the partitions but this didn't help. I have stock 4.2.2 with about 6 months of normal usage.
What are your results? Is the low random write speed indication of something?

My phone takes around 1 sec for the camera to work. I did the test you requested and my results are:
sequential read 48.8MB/s
sequential write 3.13MB/s
random read 8.62MB/s
random write 0.23MB/s
Keep in mind I'm using 4.4 kit kat on my phone. So your 0.5MB/s is actually good, might want to compare your other results.
I'm pretty sure the internal storage speed has little to do with your camera app launch.
Try setting the SD card as default storage in the camera app.
Hi guys,
I have been using almost all custom roms for redmi 1s. It's quite frustrating that for every week the memory card is getting corrupted or formatted and I see a message that "memory card is not inserted". I try to remove the battery and remove SD card and put it back then the memory shows it's empty. Even it happens for internal storage when I connect to my windows PC. It happened thrice. Soon after I stopped connecting to PC. Please help me in fixing this issue.
Thanks in advance.

Have you checked the memory card on a computer? It sounds like a faulty or fake card!

Thank you for your reply @david_inuk .
Yes, it was working fine in PC. Yesterday it stopped working completely. I'm buying strontium nitro 32 GB suggest me any good memory cards (32 GB + promising speed + promising warranty) .
Small query, is there any chances that due to over heat memory card fails or gets flashed because for me almost in every custom rom mobile is getting heated upto 75 degC
While charging.
And the same was happening with internal storage as well. Where do I'm going wrong?
mobile never gets heated upto 75 while charging on any rom, maybe you are using it while charging so never use mobile when its charging, and about card i think its a card problem try any other card, and tell what happens.
Yes, i was been testing with 8 GB memory card its working fine. The problem was in MC thank you so much @nishant12819...
Yes my mobile CPU is getting heated upto 72+ degree C..... Even if it is not on charging. Almost with all custom rom. Im using atleast 50apps and battery backup is also not good 4 or less hours of screen time(with greenify and ds battery saver).. Suggest me if any tips... with wakelock detector im blocking some of the wakelocks but eventhough its same. On GPS and Google maps while travelling around 50Kms it lasted 3hours
