Removing SDCARD for extra battery?! - Defy General

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...

Battery dead overnight /

Has anyone seen this: my battery was fully charged at the end of the afternoon, I made a few calls (not too long). The day after my machine did not react; after placing it in the cradle it finally came to life... EVERYTHING WAS GONE.
One would think that a daily sync would backup most stuff, but this has proven to me a major misjudgement of mine... My daily time4life reporting is gone. This sucks.
Anyone knows how to recover this? Why isn't the information safe on this machine?
Yep, get sprite back-up it has a battery monitor function.
Turn the Bluetooth and wifi off when you dont need them.
Save your work on the SD card
Regards
The Pilgrim
If you live in an area of poor network coverage, it is advisable to switch off the radio overnight. If the phone can't get a good sugnal it constantly polls looking for a better signal and draining the battery.
But we're living in de 21-th century... Surely some power can be held in reserve to save the memory...
It sucks bigtime!
But, I will look at sprite backup and will put My documents on the SD card.
Thanx for the tips
I had a similar issue but caught it in time...
I was using an MP3 player and had launched the camera function by accident. On taking the thing off my belt, it was HOT :shock: and had hardly any battery left.
I suppose from an 85% battery, using for 1 hour with the MP3 and camera app running had exhausted the battery. Very worrying, but more so was the XDAIIs was so hot - either the battery or the main unit - not sure.
Have used the MP3 on its own for several hours with no probs, so I can only surmise that the camera eats battery power....... so, could it have been that which was running on yours, hst?
Sorry complete newbie to the XDA IIs here after having ditched my Ipaq H6365. (I only had that for 7 days so not exactly a seasoned ppc user)
When you say you lose everything when you have a flat battery what does that mean? Is this the same as a hard reset? Installed programmes gone?
Is it all emails, text messages and contacts?
it is worrying if so as I travel a lot and sometimes might not get chance to charge my XDA and can do without losing these. is there a way to save your contacts etc to a storage card?
Thanks
For all the n00bs and people who don't know...
The XDAs have different types of memory. The Operating system is kept in "Non volatile" memory. This is safe, even without power.
Now, all the programs and your "Documents" that ARE NOT kept on a storage card and kept in the "volatile" memory. This needs constant power otherwise, it wipes it!!!! This is like doing a HARD RESET! Installed programs, e-mail, pictures, etc - GONE!!!!
As far as I'm aware there is NO WAY to recover from volatile memory that has lost it's power.
Regards,
Dom
PS: If any of this is wrong - feel free to correct me!
Well I found out that everything is gone. Still a simple user like me expects all memory to be non-volatile... or at least that when the battery is low, the system will hibernate or something, until it has enough power to operate again. I don't care about e-mail and other recoverable stuff, but I do care about the recording of my billing hours which kept in de database folder!

Installing Only On Nand = Better Battery Life + Speed

Using my phone I have tried different methods of installing the latest VanijEclair on my Tilt. However ever since I installed everything on Nand including data I have noticed that I have awsome battery life on a fresh install. I am using 2G all the time also but even with 3G on I get a little better battery life when installed strickly on Nand.
Before I settled on this method I tried installing Sys on Nand and Data on SD and I would go to work have to recharge at the end of the day because my phone would just die. The only thing that I can think of is that even when the phone is off the sdcard is constantly reading and writing data sucking down precious battery power throught the day.
Although when installing strictly on Nand you don't receive the benefits of more space you do gain speed I think as my phone is pretty smooth so far.
Has anyone experienced this?
My view is this, when we flash the NBH, it creates 4 partitions in nand, one for boot, one for system, one for data, and one for cache, ( I think that's correct, please let me know if I'm wrong), anyway, if we install sys on nand, data on SD, what happens to the /data partition on nand? Is it magically transformed into RAM or something else? No, it just sits there doing nothing, you could hack the partition sizes to free up more space on system, by 'stealing' it from the redundant /data partition, but that has no real benefit either, apart from being able to install huge experimental builds, like a hero/sense one I'm playing with, ( no it won't boot, and it's so old it has cobwebs on /system/media).
So why waste that space, I've always used sys and data on nand, and tried to control my bad habit of downloading every damn widget and app i like, because I'm really only going to use once, or maybe twice, and battery life is something that 'improves' with use anyway, ( it's called battery calibration, the longer you use a build, the better the battery calibration gets).
I do think that the ideal set up would be similar to the one I use on my G1, sys and data on nand, ( naturally), sd card partitioned 64,512 swap/ext2, the remaining space fat32, use apps2sd and either swapper2 or enable swap from spare parts, (some builds have that option, unsure if it works on kais tho, something else to play with if I get the time).
The reason why battery life is worse using SD may be that is just less efficient anyway, it's certainly slower, and ties you to that SD card, which is usually fine, but occasionally like to transfer data, and removing the SD is possible if it does not contain part of the OS

[Q] sd card battery drain

SDcard show up under battery, surprising since there is no sd card in a galaxy nexus..
Anybody know what's going wrong or how to stop the battery drain ??
I've had this exact same issue! It happened at the same time as my other issue of app sizes continuing to climb upwards and the phone getting laggier in this thread:
http://forum.xda-developers.com/showthread.php?t=1715363
I just resorted to a factory reset, which resolved the problem. Sorry I can't be of much help, as I still have no idea what the issue is, but it was definitely taking a noticeable toll on my battery life.

I would be concerned of what you have installed on your device, that it is calling itself sdcard.
Nexus internal sdcard is mostly named just sdcard, but this is first time i see it in battery stats. Maybe it's some bad app? Maybe you should uninstall apps one by one and see if it's go away.

Nexus does not have an internal sdcard and symlinks cannot use battery so I would say its an app.

I mean that 16gb internal storage which is called sdcard in most apps. And i know that it can't be in battery stats, that's why i said it's an app.
Same problem, a solution without having to do a factory reset?
Anyone come up with a solution here?
So I'm guessing the lack of responses in this thread (and this one http://forum.xda-developers.com/showthread.php?t=1792361&highlight=sdcard+battery) means no one has any idea why SDcard usage would be so high?
Maybe it is not the amount of power that sd card uses, it is amount of power that the phone uses to read the sd card. If you did lots of things that needs reading from sd card, battery show that kind of information. Some program with wrong commands may couse this

Thats what I figured but there shouldnt be anything thats accessing it, especially overnight in sleep mode, the SDcard has more CPU usage time than any other app, by a landslide.
Have you looked at your running apps? (Settings>Apps>Running)
Maybe you can find out what app may be running called "sdcard".
Sounds a bit fishy. While there is no physically removable SD card, the phones internal memory is partitioned so you have some space which is recognized as the 'sdcard'.
In any case I've never seen anything like that in my battery drain, and even if there was, it definitely shouldn't be draining those amounts while the phone is idle..

I've gone through them but can't seem to figure out whats going on...i've also run logcat but that hasnt turned up any useful info either.
And when you press on sdcard under the battery usage, what screen shows up? Does it say it's an app? Could you provide a screen shot?

Here are screenshots from my battery usage, after clicking on the app, and my build info. I've got the same thing and its completely eating my battery life. This was within 1 hour of use.
This just started happening to my galaxy nexus -- no idea why?
GSAM Battery Monitor shows System (sdcard) running at 17% and its really affecting battery life, I can actually watch the number drain by the minute.
I am not looking to do a factory reset again and I am running Bugless Beast 4.1.1 rom and have been for about 2 months now and never had this problem, anyone have any idea what could cause this?
Just started happening to me today. I just installed lookout so I hope that is the problem. Just uninstalled it to see if that was the culprit.
I'm 100% certain Google Music is causing mine.
Mine always says sdcard and media are the processes running that are eating my battery.
I can reboot and fix the issue, temporarily, but as soon as I play Google Music it starts back. I'm going to clear data and cache (for Google Music only). Now that I think about it this has been happening since Google Music's last update ~1 month ago.
I'm running the latest Trinity kernel and RasBeanJelly, but this happened while on Bugless Beast as well, so it's not a kernel/ROM issue either.

Android System is using more battery than my screen.

Why is my android system taking so much power all of a sudden? Worrying.
Welcome to the sad party We have been discussing this in the OTA update thread as well. I've never had Android even close to Screen usage before. Now it's constantly there. And sadly no root for greenify or wakelock viewing.
Mine just started this after a very long charge. Plugged it up at like 9:00 am and it just finished about 10 minutes ago, very strange. It seems to be going back down to normal though.....
It's been higher since the last OTA update. Hopefully it will be fixed when lollipop gets released.
That happens to me on the original build maybe once a month. I just restart my phone and it goes back to normal.
Android System battry drain after OTA update
I haven't read through the other forums, so forgive me if I'm suggesting something that's been suggested elsewhere, but I was able to fix mine by disabling HDVoice..
Settings>Data Usage>Mobile Data>Enhanced 4G LTE Services
After I unchecked that I'm back to where I was pre-OTA.
All of you having Android System running at high %'s, can you answer two questions?
1) When you go to Settings> General > Battery and tap on the graph, does your Awake graph show as mostly awake (solid blue lines) when the screen is off (no lines next to Screen On)?
2) Do you have an external SD card in your phone?
I'm asking because I'm also having high Android System battery drain. My phone is also always "Awake" according to the battery graph (in other words, it isn't deep sleeping, so my battery is draining faster than it should). I just removed my external SD card for a while and now my phone is magically deep sleeping. Well, obviously not using your SD card is not an option for many people... myself included... all my music is on mine! So I'm trying a few things to allow me to keep my card in and to have my phone deep sleep. I'm just wondering if there's any similarities between me and anyone else.
UPDATE:
OK, so what I did worked.
If you have an external SD card, then do this:
1) In Settings>Applications>SD Card, I moved any checked apps to internal storage.
2) I then copied all my music, photos, videos, etc to my computer.
3) Then, with the SD card in the phone, I went to Settings>Storage and formatted the SD card.
4) I then copied the files from (2) back to the card.
After that, your phone should not only sleep better, but Android System should begin to move down the battery usage list after many hours. Just over night, it went from about 38% usage to 20% usage and is now #2 on the list. Cell Standby is now #1. By the end of the day, I expect it be even lower.

awake matches almost identical to screen time,
And i haven't tried the sd card one, although i've gotten a new one.
Anyone try this with success?

It worked for me (obviously), but it wasn't exactly meant to be a solution for everyone. Eventually, Android System became the highest drainer again, but on Lollipop, it no longer is. Again, that's for me.
Try removing the card and leaving the phone asleep (screen off and not doing anything) for a few hours. If the awake time decreases dramatically, then it may be the SD card causing problems.

[Q] Memory card getting formatted or corrupted every week

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.

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
