[Q] high battery consumption with 32gb sd card

Hi,
I have bought a 32GB micro sd card from Sandisk, recently. Before I had a 16GB from Sandisk. With the new card I suddenly have a battery consumption in standby from 15 to 20% over night. Before 3-5%. I thought it must be something wrong with the card. I ordered a 32GB card from Transcend - and it´s the same behavior.
So, what is this?? It seems that with 16GB all is fine and with 32...
There are no active programs, no data connection and nothing installed on the card. I have formatted the card again in the device - nothing changing.

Put the card in your computer, copy all the contents off it, format it and copy them all back on. Don't format the card in the phone.

I had same problem with a Sandisk 32GB which was bought from a reputable reseller. Tried everything and in the end gave up and now live with a 16GB just fine.

Strange ........ I am now with Sandisk 32gb for 4 month and absolutely nothing changed in batt drainage ...... 5% overnight with all caches possible moved to sd.
Maybe depends on interval wm has to write to storage card ? email-att., update files? meaning that batt consumption is higher for each read-write cycle ?

This is what I have tried first: Copy all my stuff on the card and put it in the phone. Later I have formatted it in the PC - copy all stuff - put it in the phone.
At the end I have formatted it in the phone, without copy anything on it.
No change, the same behavior, whatever I have tried.

This would be logical, when there is something to write on the card. But I put the blank formatted card in the phone! No apps installed on it, no e-mail, etc. Closed all apps and no data connection, wlan, bluetooth, etc. Pure standby!

Now I am happy with ROM 3.14!
I have updated to ROM 3.14 and now it´s working! Power consumption for both cards 16 and 32gb is equal now. Seemingly it was a malfunktion in the 1.48 ROM in conjunction with 32gb cards.

i think the problem is that you have not installed the sd card hotfix from htc on your 1.48 rom...which is usually included in next versions of rom
"Update for HTC HD2 SD Card Storage Cards
This update for HTC HD2 allows the HD2 to properly read the amount of free space on a storage card, so you can take as many photos or videos as possible. It also enhances support for some sizes of storage cards."

Should not be the problem, because I had ALL updates installed on the 1.48 ROM.

Solution to SD Card Problems!

I started using my HD2-7 with an 8Gb class 2 Sandisk SD card that worked perfectly. But I wanted a bigger SD card, so I bought a 16Gb class 2 Sandisk card that gave me a lot of hanging, reboots and lags in the HD2. I had to abandon the card and went back to the 8Gb card...until I stumbled on this post. I followed it and now the card has been working perfectly for about 4 days without any trouble.
If you are having trouble with your card, please try this method and post your result. I think the guy might have stumbled on the solution to the SD card problems.

Many people are experiencing problems with SD cards and/or random reboots, and I think I solved mine (I am rather a newbie), so here is my report.
Few days ago I installed WP7 (thanks a lot, DFT guys) on my U.S. T-mobile HD2 with its original 16 GB class 2 micro SD card, using radio 2.10.50.08.2.
Installation went very well, the phone worked very smoothly and very fast, except it started freezing and randomly rebooting. Hard resets didn't help. Then I removed SD card and reset the phone - it worked very well and fast and did not have any reboots.
I tried reformatting the SD card to Fat32 (using free software SDformatter - it fully clears the card after WP7 use and removes partitions, make sure you put Format Size Adjustment "ON" in Options) and reset the phone with the card. It did not help, the reboots were the same as before.
So I decided that the 16 GB card wasn't good for WP7 and bought a PNY 4 GB class 4 card for $10 at Staples. I reset the phone with this new card inside. At first everything worked very slowly, but at least the reboots completely disappeared. In few hours everything became fast, except for certain things, like it would take 15-30 seconds for the camera to reset after shooting a 1 min video.
Finally, I decided to try something else. I reflashed radio to 2.15.50.14 with the original 16 GB card (reformatted again), and everything seems to work very well -it's fast, and there has been no reboots so far in few hours. The battery also seems to drain with a normal pace.

The guy did alot of different thinks to try to fix his SD card problems, in my opinion it would be hard to identify what actually fixed the problem if any. I had 2.15 radio and changed it to 2.10 as others where saying it would lower battery drainage which it seemed to have changed slightly. The only reason I posted this is to just make people aware before they start reseting there phones with experiments but I also understand that without the above sort of posts the forum wouldn't exist as so much is discovered by experiment.

32GB SD card issue - validated card as 32gb

I purchased a 32GB micro SD card for my HD2 after my 16GB card died last week. A sad day indeed, but an ideal time to upgrade
I've read a lot of threads on the forum about some people having issues with 32GB cards, and fake cards. This has prompted me to run H2testw, and also try formatting using SDformatterv3.
HD2testw - Verified as OK.
SDformatterv3 - Completes OK.
Now, when I add the newly formatted card to my phone, it mounts, and works fine. No problems at all. I then start to fill up the card with music. I firstly copied about 5GB to the card, and again I had no problems. The card works fine in the phone. I then copied another 10GB to the card. However now I have a problem. With the SD card in the phone, the phone hangs. When the phone is in standby, I press the power button and I get a black screen. If I remove the SD card then it starts to work correctly again.
So, my first thought was, duff card. So, running the programs above verified that the card is OK.
So, I am now wondering if the phone actually supports 32GB correctly (IE, when more than 16GB of data is on the card). I also thought that perhaps the ROM I am using is the problem.
I am running [CWR] BOYPPC-SHIFTPDA_GINGER 2.3.4-Sense.s V25 (24.May) ROM. I see that V35 is the most up to date rom, so perhaps I will need to reflash my phone. I will be testing this later today.
Has anybody else found themselves in a similar scenario, and did you find a solution?
Cheers,

I figured it out. Turns out to be a combination of things.
1) MIUI player locking up when trying to scan newly added music
2) Locking up because of some corrupt files
Tracking down the bad files resovled the problem

good to see you solved it, cuz i have a 32 gb class 6 and no problem.
some to notice its that to some ppl a 32 gb class 10 works with some bugs, a class 4 or 6 seems to works better.
PS: if you are a flashaholic like me, you should have partition your sd card with CWM partition option, so you could use some of the beneffits of sd/ext that some ROMs use

So 32 Gb works well with Htc Hd2. But, it depends which company and speed.

That's the thing: I bought brand new 32 GB SanDisk and am using MIUI JB. Constantly upgrading with their daily build to new versions to no avail.
Problem: I filled card with my files to listen. Initially it works alright, after some time however I find some folders are gone, some files are gone, things just dissapear from the card.
Now I wonder is it a card, is it a MIUI JB or is it HD2 that got broken after my intensive use. Some electronics burnt down or something.
Does anybody had this issues : combination of HD2 with MIUI JB on 32GB card (NAND or SD - both). Keeps losing files in very consistent manner.
I also checked the card with different software and formatted it many times and re partitioned.
As an experiment I am trying now old 8GB card to make sure if its card or not.

[Q] how many apps will note be able handle ?

hi
I face phone restarts once or twice a day
I have 200 apps including 4to 8 HD games
I have 16Gb class four SD card
During these restsrts if i remove the sd card then everything goes
Normal.
Should i go for class 6 memory card
Or uninstall more apps
I have 10Gb free space in sd
1gb free system memory
And 2 gb free phone memory
Wat should be done

Two restarts a day is not normal - only time I had that was with a very early ROM. Have you tried different kernel or ROM?
Are most of your apps on the SD card? Seems that there are some dodgy SD cards out there.
What I would do is backup all of the apps, reformat the card and then load your favourite apps back on to it and see how it goes. Do you use 200 apps regularly? Just use the favourites for a while. Also maybe try a different SD card?

am still with my stock rom
all the possible apps moved to SD card , i just use those apps once in 2 or 3 days
only 4-6 apps i use daily .
should i go for class 6 SD card , currently am using transcend , should i try someother brand , if yes which one

Transcend is good brand. I've used it and a few other commercial ones (don't want to advertise!)
I have a Class 6 and Class 10 (and a cheap Class 6 one that I think is really only class 4 - it plays up and pixelates on videos)
If you can afford it definitely go Class 6 minimum. (PS I used Class 10 interchangeably on my DLSR for HD videos so I know it works well)

I would recommend formatting the card from the device itself and try again. Even 500 apps shouldnt crash the sevice. I have found several root apps that can crash the device but normally it shouldnt happen.
Transcend are a good brand and I wouldnt worry too much about the card unless its damaged.
The phones can be funny at times about the filenames in tye root of the card and i have found corrupt videos and images can sometimes crash the media scanner.
If youre capable, try get a dmesg log and logcat which might be more helpful if the problem persists.
Hope you have more luck now.

SD Card stopped mounting, permanently

I think my S4 just broke...
Basically I woke up with a message on my phone "sd card was unexpectedly removed". I had been sleeping so this happened during the night sometime. It appears no sd card will work in the phone now.
I've done the following:
- rebooted multiple times.
- removed and inserted another sd card, no change. Attempted this with two spare sd cards.
- Settings -> Storage -> Mount option is grayed out regardless of the sd card in there or not.
- all the sd cards were verified to be working in another phone and on PC.
So as far as I can tell my S4 just decided to blow the sd card port over night.
Logging in via adb shell it seems like the block device for the sd card is gone as well.
Any tips?

I had a similar problem.
The SD card i had was bad and the others were old and well used.
Apparently not all class 4 or higher SD cards are good quality these days even tho they work in your pc or older phone.
Try a brand new sd card.

Try a different rom or if you have a nandroid from before the issue started try flashing that.

I had a few SD Cards laying around. They work in other phones. The one in my S4 is not a cheap sd card either and has been working perfect in the phone until today. That sd card works fine in other phones (LG OG for example).

My S4 has only been motochopped and that was over a month ago. Everything has been working fine. The phone was not even in use last night it just happened over night while the phone was charging. Now it refuses to mount any SD card or at least the 3 I have tried.

Yeah, I get that. I'm suggesting that you try and find out if it's software or hardware. If it works with a different rom it's just software, if not it's hardware.
