Nexus 7 horrible lag/battery life

[Josh Howell]

Hello. I've had my nexus 7 for less than a year now. I have been recently having some problems with extremely bad lagging and freezing. Nothing runs smooth anymore and animations are choppy (for example, opening Google chrome). Another thing is battery life. It charges super super slowly with the standard ASUS charger and with another charger of the same rating. It also sucks battery incredibly fast (about 5% every 2-3 minutes). What do?

Have you tried a factory reset?

 

[Josh Howell]

Not yet.

I have some apps with important info on it (ex. Adobe Reader has important PDF's) and I can't lose those. What can I do about that?

This article might help. I suggest trying a cache partition wipe first.

Okay, checked that. Battery was connected just fine. Trying the cache wipe.

You can't even get to "Recovery Mode" using the volume buttons to select?

When I get to Recovery Mode, it gives me that error.

Install Battery Doctor and set it to kill power hog apps.

I've never seen it say "No Command." Are you rooted? When I Google "Nexus 7 no command," a number of posts about rooting and ROMs come up.

And to answer your earlier question, you can always save the PDFs on your Nexus 7 by uploading them to Google Drive or some other cloud service. You should be able to locate those files easily with a file manager app like Total Commander or ES File Explorer. After you've backed up your important information, then you could factory reset, if you're still interested.
