I still have about 2 GB of internal storage free but I also have some spare micro SD cards and I wonder if installing one can hurt my battery life. Google revealed that the card may drain like 1 mA continuously when idling. This means that the card alone will drain 1500 mA/h battery in about 2 months which is quite Ok and you should not probably care about that. Is this true, or having the card installed may visibly affect the battery life? Thanks.
I installed a 8GB card on my photon and I can't see any difference on my battery life due to having it.
All my pictures/videos go to that one

I am new to this tablet Arnova 10 G2 (101c). Got it like 2-3 days back. Trying to know it better, so don't flame me please.
I got the rooted firmware on through one of the bundled apps - arctools. So now, here are my questions:
1. Camera:
My camera works. But I can't see where it stores the pics. Even doing a media rescan in settings menu doesn't seem to help.
2. Internal Memory:
On the back it says the model is 4GB. But inside, when I am browsing in root explorer I see over 7 GB free. I have copied over 4 gigs of pdfs (books), and still have over 3 gigs free. Over 7 GB free space on internal SD normally translates to a 8GB model. This has got me perplexed.
3. Battery:
Installed battery calibrator. I drained the battery full until the tablet shut down by itself. Then I charged it to 100%. Used the battery calibrator to delete the batterystats.bin file. Then charged it until the light was green with the tablet off. Turned it on with charger unplugged.
I put it on a movie at about 60% brightness. After about 5+ hours, it was at about 55-60%. Then I took off the movie for some time, turned the brightness to 0, and was doing some browsing, and now I noticed battery at 65%. Battery usage details show spikes moving up while I was simply using it and no charger connected.
Is this normal? How long does it take for the battery to normalize?
Someone help me please. Even after 3 full charge-discharge cycles, my tablet when kaput from about 30 to 0 last night!

Regarding the pictures I won't help you till I have the tablet but speaking of storage you clearly got the 8gb model if you're sure there's no external (micro sd ) memory counted
Regarding the battery it seems that you messed too much with it unnecessarily and now (guessing) the battery electronics freaked out or the li-ion cells got damaged because of a deep discharge.
try to use it normally charging from say 10-50% when needed to full and after some cycle maybe it will get better ?
this isn't the Arnova 10g2 (Philly tablet) your speaking of is it?

I don't really know about this. All I did was a couple of full charge-discharge cycles, and nothing more.
And it showed ~7+ GB free on internal memory (without any sd card inserted).
Update: I normally keep my microSD card mounted in my Prime. After doing some searching, I've seen a few reports of battery drain being bad when having an SD card mounted in the Prime and/or the Prime's dock. I unmounted my SD card and my battery life has greatly improved. Give this a shot if you currently always leave your microSD card mounted and have battery drain problems.
Has anyone noticed this wakelock killing their battery? My problems just started recently. I charged my phone overnight and did not use it all day. This wakelock was literally running the ENTIRE time my tablet was on - for over 12 1/2 hours. It brought my battery down to 80% without me ever turning the screen on. Has anyone else noticed this problem on their Prime, or does anyone have any ideas on how to solve this? The only thing I changed recently is I installed System Tuner Pro, which I just uninstalled to troubleshoot.
i would like to know how if i charge my dock up and then 2 days later connect it to my prime it lost 20 percent of its battery. Maybe the batteries also have a
discharge built in , IDK?????????????

I had that problem with the TF101. My dock battery would completely discharge in 2-3 days without ever being connected.
My TF201 holds its charge for weeks with losing more than a few %.
Asus really needs to get it together and develop some consistency with their tablets.

Not exactly, but that sentence was definitely confusing. I just edited it for clarification. Thanks.
No difference here.

Interesting. I wonder if the contents of the SD card makes a difference (i.e., I wonder if my Prime keeps continuously scanning my SD card for some reason).
I have a galaxy s3 and recently i brought a class 10 sandisk memory card. . What i am observing is my memory card seems to be draining my galaxy s3 battery. For example on 100% charge, after 2 hour it goes to 80%. The very next day i used my galaxy s3 without memory card and to my surprise it went through the entire day with only 75% charge. This has drastically improved my battery life by not using a memory card. Has anyone experienced this problem. Please help me with this
And yes i have formatted my memory card and also used a new one but no help
Model No. I93000
Android Version - 4.1.2
I have a 64gb SanDisk UHS-1 high speed card, and have kept it in my Note since Day 1.
Recently, I took the microSD out and used the phone for 2 days without it. What I noticed is my battery life has been amazing since. Currently, I am on 94% after 3h 7m 32s on battery. 7 minutes of screen time. This has been very consistent on the same JB 4.2.1 preview 7 rom.
I know others have posted this kind of good battery life before, but I've never had this luck myself until now. I did not do anything differently except for taking the micro sd card.
Any thoughts on the relationship between microSD and battery life (especially a SanDisk UHS-1 high speed card)
I think the 7 minutes of screen time out of 3 hours has more to do with it than the MicroSD card. Of the possible 170 minutes you used it 7. That will give you amazing battery life itself with those kinds of usage results. I use a 32GB MicroSD and I get well over 14 hours a day of usage on JamieD's Preview 8.1 with JB 4.2.2

This.
Screen>all when it comes to battery life.
I did a fair amount of research on this phone - I was particularly interested in the camera after reading some glowing reviews. Then I got sidetracked about the large screen (for one handed use anyway), 4G. IR blaster etc. And completely forgot about checking for SD card slot.
Anyway, got a 16 GB version from ebay and realised it only has 10 GB available. So, I'm wondering if any ROMS manage to improve on that number? Even 11 or 12 GB would be better?
As I know, you must change the partitions, also in small roms like Cyanogemod (300mb or something like that) the system partition takes 2gb space. I think it would be very risky to change it. Let's hope some other person reply
Even I'm planning on buying the 16GB variant. But I'm not sure if that'll be enough for me...
Go through all the crap you plan to copy over to the phone, and skip the stuff you rarely or never use. I bet you'll have plenty of free space. Encode movies to be smaller, and put fewer of them on. No big deal.
and buy a mini 32 or 64gb dual usb/mini usb stick and you're covered...
Unfortunately those sticks consume quite a bit of battery while plugged even in idle mode (on the LG G2).

didn't notice any battery drain when i used my sandisk mini usb stick...
it's not ment to be constantly connected to the device...
i use it for bigger file transfers from pc to phone (vice versa), backups in twrp and keeping the essential files in case of bad flash or smtn...
never had it connected more than 10 minutes...
twrp backup of 3.6 gb takes some 500 seconds, and the battery went down by 1-2% max (mostly because the screen was turned on)
