Nexus 7 - Battery replacement


Asus battery for the Nexus 7
I guess after two years of usage it is time to replace the battery.
I actually got to this understanding after having a few problems with my Nexus 7 which I love a lot.
The tablet started heating up a lot, very fast and the charge doesn't last as long as it used to.
To add to the list of problems, I recently had a few random restart issues the last of which was after the screen froze and showed me a verity of rainbow colors. The only way to stop the tablet was a forced shut down after which the Nexus refused to start-up again. I eventually fixed that issue by disconnecting the battery and reconnecting it after waiting a few seconds.

All this however didn't fix the worst issue, I cant charge the Nexus 7 when its turned on.
I have to shutdown the tablet to get it to charge.

Of course instead of replacing the battery I could just wit a few weeks and get the Nexus 9 that was just announced (and I'm definitely going to do that) but I'll probably keep using the Nexus 7 after installing the new Kali on it.

Battery Replacement Tutorial

If I'm going to replace my Nexus 7 battery I might as well write a tutorial.
So to replace the battery of the nexus 7 we first need to remove the back plastic cover.

The cover is held by plastic hedges on the case so be careful and start from the bottom of the device.

The next ting to do is disconnect the battery from the the motherboard connector. Be careful not to damage the connector itself. I used a fingernail but you can also use a small flat-head screwdriver.
Since we'r not going to use the old battery, you can also try to pull the battery cables gently.

Next we need to remove the battery.
This is not as easy as is seems since it is glued to the tablet.
Just pull it slowly from the top, it wont damage anything.

Once the old battery is removed you can put in the new one, connect it to the motherboard and close the cover.
Next turn on the device to make sure the connections are good. The new battery would have some power on it.
After the check I recommend shutting the Nexus off and charge it until the battery is full.

That's it, very simple to do and shouldn't takes more than 5 minutes.

The new battery fixed all my issues but one.
I still cant charge the Nexus 7 while the Tablet is turned on,
Drop me a line if you have an Idea on fixing it.
