Nexus 7 resurrected

I still have my Nexus 7 laying around for a couple of years. It used to be a good tablet untill Google released the OTA update from 4.4 to 5.0 that killed the device. After the update I can barely use YouTube and some basic apps like calendar, Amazon reader... It's so laggy that I had to give up for a new tablet. Bravo Google! Brillant!
 
As the old battery doesn't last long and it charges very slowly, I decided to replace the battery with a new one.

But the charging is still very slow, it takes up to 8 hours to fully charge the battery. So I open the device again to clean the central connector cable that connects the charging board to the mainboard.

After the cleaning it still charges slowly. So I ordered a new charging board from eBay that should arrive in a couple of days...
 
Have you tried different chargers? I've got an old Samsung tablet that will charge very slowly, even with the OEM charger, but when I plug it in to and Anker power pack, it charges in 1/3 the time.

Yes I tried a couple of chargers ranging from 2A to 4A, but the tablet never reaches the usual 800~1000mAh charging speed like before. So I think I should replace the charging port before making a conclusion.
 
Just an update, the charging board arrived, I replaced the old one with this. Everything works fine but there is no significant improvement when it comes to charging speed, so the problem is somewhere else.
 
I know what you mean. My Nexus 5 recently gave up the ghost. It served me well, and I had grown fond of it, but my new phone just blows it away in all departments.

Sure, even the 2013 version with 2GB RAM already has a nice performance boost.

I will downgrade the tablet to its original KitKat when I have time. Android 4.x can run with just 512MB RAM so if I succeed, the tablet would run smoother with its 1GB RAM.
