Just a question of wiping battery stats - Nexus 7 Q&A, Help & Troubleshooting

I have a question about wiping battery stats, I managed to soft brick my rom so I reflashed to stock. Should I wipe battery stats again just like installing custom roms or no?

no.
theres actually nothing you need to wipe the battery stats for. its more of a choice if you want to wipe them. it doesnt affect anything when flashing/reverting.

Possible brick :(

So, just a few hours ago I decided to install ADWLauncher, then I noticed my phone was acting VERY sluggish no matter what I did;uninstall ADW, restart, wipe cache, dalvik, and now my very last attempt is nand restore...but I'm getting the error "Error: run 'nandroid-mobile.sh restore' via adb" I'm not familiar with adb, so bear with me.
If it's any help, I'm on Virus ROM with Carbon theme.
I've had no prior problems like this or at all.
I know how to use a computer and do commands, but I'll need some guidance with adb, etc.
--------- I tried posting in Q&A but no replies thus far and I'm freakin' out because I really need my phone.
Try charging your battery for awhile...

I was hoping that would be the solution, but I popped in my fully charged battery and keep getting boot loops too, and still won't restore my backups...
We wipe the system and instead of restoring the NAND backup just load up a new ROM. You can restore after you get it working.
Try that.

Wiping the system as in wiping data/factory reset, wiping cache, wiping dalvik?
Sweet Jesus, I fixed it! I did what you suggested although I tried that earlier and it didn't work. Thanks a lot guys.

when wiping battery stats...

im trying to recondition my battery. when im wiping my battery stats in clockwork, i encounter a weird problem. right when i confirm to wipe the stats, it just goes back to the menu options. What i mean is that clockwork doesn't tell me that the batttery has been wiped or anything, something that you would see from an Amon-RA recovery. does this mean that it didnt work? please confirm this. thanks
I think it works, just no notification, you just have to trust it
The cake is a lie!

Wiping battery stats

When you click wipe shouldn't it say something like complete? I'm using cwm3 ext4 trying to wipe my stats but it doesn't say anything. Does it normally say anything
ive never seen it say anything either. im using cwm3 as well.

Battery stats

Does it matter to wipe battery stats after flashing a kernel, then doing a bump charge? ...Just to recalibrate it, and get an accurate read.
I've never wiped battery stats since I've had this phone.

I only wipe after major changes. Stuff that would effect performance a lot
Sent from my HTC EVO shift 4G running the latest and greatest cyanogen using the XDA app.
No, it doesn't matter to wipe battery stats after flashing kernel. It only matters when the /data/ partition gets wiped, because that's where the battery stats file is stored. That only means whenever you do factory reset, which wipes /data/ of course

Yes it helps. Here's a good guide for Battery Calibration.

So basically when flashing a new ROM, I would do a full wipe, and that too would erase battery stats?
I don't let my phone die fully, charge it completely, or even bump charge it after I do a full wipe. Should I start doing that?

If you're flashing an updated version of the same ROM over the old version, you usually don't have to wipe, and don't have to do anything with battery stats. I think if you do a full wipe and flash a new ROM, try to do it when your battery is full. If not, just charge it to full and wipe battery stats later. Bump charging is debatable, and up to you.

Try titanium backup for your apps, the free version asks you to confirm every app reinstall, but it's free and saves your data plan
Have you cleared cache and dalvik cache? I updated yesterday and only lost 2% over night ?

I have clear caxhe on recovery and on fastboot, but the Device Idle always on second list after SoT...
Use titanium backup and backup all your apps and then do as freenicco suggests and factory reset. If after the factory reset your phone battery is good, load all your apps back on. Otherwise, try re-downloading the firmware and flashing again, maybe it got corrupted.
I solved this by reflash the recovery and fastboot, my recovery is corrupted...and reflash the Nougat update
