Don't buy a new ROG Ally X handheld — Upgrade your original ROG Ally's battery life with this replacement kit instead

The Drake meme showing Drake shunning the ROG Ally X but approving of the ROG Ally with a JSAUX battery upgrade kit. .

I've previously written a guide on how to factory reset and sell your ROG Ally in order to get a better handheld.

However, the sad truth is that the original ASUS ROG Ally gaming handhelds generally don't retain their value when sold or traded in anymore.

For instance, even if you've kept it in really good condition and still have the charger, Best Buy only offers $160.00 when you trade in either the Z1 (non-Extreme) or the Z1 Extreme version. Meanwhile, it can be hard to sell your used Ally on eBay, Facebook Marketplace, or other similar services.

So, instead of trading in your original Ally for another handheld with better battery life, like the improved ROG Ally X, it might be better for your wallet for you to just upgrade your original Ally with a greater battery capacity (and maybe even a larger SSD).

I've already upgraded my ROG Ally, so I've put together this page of tips on how to do the battery upgrade correctly.

What you'll need to upgrade your battery

The original ROG Ally has a 40Whr battery while the ROG Ally X has an 80Whr battery. As seen in my JSAUX ROG Ally Battery Upgrade Kit review, this kit provides a 65Whr battery, which is better than the original, but doesn't last as long as the ROG Ally X's stock battery.

JSAUX Battery Upgrade Kit: Tips and things to know

JSAUX provides a video tutorial as well as step-by-step illustrated instructions for upgrading the ROG Ally battery at the JSAUX website. I've embedded the video above to make it easier to watch.

All in all, the upgrade process itself is relatively easy, but here's what you need to know and what you should consider before doing it.

  • As with most tech upgrades, if you aren't careful during the upgrade process, you could permanently damage your handheld. Follow the instructions and use the proper tools correctly to avoid complications.
  • You'll want to perform this upgrade on a clean, dry surface. I did mine on this self-healing mat, which sells for $8.99 at Amazon.
  • Unlike the other ROG Ally back screws, the bottom middle screw isn't intended to come out all of the way. You'll want to unscrew it as much as possible and then open the casing with it still in the screw hole.
  • I found it easiest to pry the Ally casing open by using the triangular prying tool in the seam near the bumper area.
  • The included blue gloves are shock resistant, so you should wear the gloves during the upgrade to prevent accidentally damaging any of the Ally's internals.
  • The prying bar is helpful for interacting with latches, such as opening and shutting the ribbon clasps or locking and unlocking the piece of metal holding the battery cable in place.
    • Pull up from behind the ribbon latch to move it. Meanwhile, gently press down on the metal above the cable and then slide it up and down to safely unlock the wires.

  • It's also worth noting that after installing the new battery, you will need to plug your handheld into its power cable before it will turn on again. This is expected, considering you've just swapped out the battery, and the new one won't have any juice.
  • After the upgrade, your handheld might take a while to start up after showing the initial Republic of Gamers logo, but that is to be expected. Leave the handheld alone and allow it to start up at its own pace.
  • Going through with this upgrade will void any active warranty that you have for your Ally. So keep that in mind.
  • The new ROG Ally back plate doesn't have textured grips and feels a little too smooth. To fix this, you might want to purchase non-slip grip stickers from Amazon.
  • Since the new backplate makes the ROG Ally 1mm thicker than it originally was, form-fitting protective cases, decal wraps, and vinyl skins might not fit the upgraded Ally.
  • You'll want to reach out to JSAUX customer support if you have any issues during the upgrade process.

If the battery upgrade process was done correctly, the ROG Ally should behave normally after it's been booted up again, only with longer battery life.
