Zenfone 9 Battery Life Review and Comparisons

Who doesn’t love great battery life? Yes, ASUS upped the battery in the Zenfone 9 compared to the Zenfone 8 but in real terms, does it make a difference? If you want a mobile phone with the best battery life in a phone that isn’t a giant, the Zenfone 9 appears to be king of the mountain.

We are going to delve a bit into a very reputable website that did a deep dive in the Zenfone 9 battery life. Tom’s Guide, aka Tom’s Hardware are a top-of-class reputable website that has a rich history of reviewing every product under the sun. They have the best testing guidelines that they apply to all the mobile phones so you can be assured that their findings are accurate across the board. In their word you can trust.

To make this a fair fight as it were, the Zenfone 9 should really be compared to devices of a similar ilk. So certainly the ASUS ROG Phone series is going to beat most every mobile phone out there when it comes to battery life. However, it’s also a much bigger device which of course can house a much larger battery. So battery life is quite relative. The Nubia RedMagic at spot #2 and #5 is also a gaming phone, so keep that in mind when you notice where the Zenfone 9 is sitting in the rankings.

Here is the list of Tom’s Guide for the best battery life for mobile phones:

  1. Asus ROG Phone 6 Pro: 15:30
  2. Nubia RedMagic 6: 13:20
  3. Moto G Power (2022): 13:15
  4. Asus Zenfone 9: 13:13 (tie)
  5. Nubia RedMagic 6S Pro: 13:13 (tie)
  6. Moto G Stylus (2022): 12:30
  7. Kyocera DuraForce Ultra 5G UW: 12:29
  8. Asus ROG Phone 5: 12:23
  9. Samsung Galaxy A52 5G: 12:19
  10. iPhone 13 Pro Max: 12:16 (tie)
  11. Cat S62 Pro: 12:16 (tie)
  12. OnePlus 10 Pro: 11:52 (tie)
  13. Moto G Pure: 11:52 (tie)
  14. TCL 30 V 5G: 11:46
  15. iPhone 13 Pro: 11:42

So from this updated list of 2022 phone releases, you can see the ROG Phone 6 Pro sitting at the top. There is a cluster of mobile phones in the #2-5 spots that are around the 13 hour mark. That is a very impressive battery life to be sure, and check out the Zenfone 9 vs. the ROG Phone 5. It beats it! Many would call Apple iPhones have the best battery life on the planet. Tom’s Guide comparisons say otherwise. If you consider that the iPhone 13 Pro Max with its 12:16 battery life is the best that Apple has going currently, you can see that the Zenfone 9 is extremely impressive. Note that the most comparable iPhone to the Zenfone 9 size wise is the iPhone 13 and it’s not even on the list!

People may quibble about lack of wireless charging on the Zenfone 9 but clearly you won’t need to charge you phone as much. Perhaps a small conciliation for some. ASUS does provide a 30W charger in the box so that will top up your battery quickly without too much fuss.

It’s interesting to think about whether the Zenfone 9 battery life is a result of ASUS engineering of if it’s the work of the new Snapdragon processor. Most likely the new Snapdragon processor has tremendous efficiency and lower heat which translates into the results see by Tom’s Guide best battery life chart.

It’s also worth noting the size of battery in these phones. The Zenfone 9 has a 4,300 mAh battery compared to the Zenfone 8 which has a 4,000 mAh battery. The ROG Phone 6 Pro has a 6,000 mAh battery compared to the ROG Phone 5 which has a 6,000 mAh battery as well. The results indicate that newer Snapdragon processors are making great strides in terms of power efficiency. Yes, ASUS has some clever designs for cooling which help as well, but we would suggest the largest factor comes down to the processor itself. Which is why you don’t see any Google Pixel phones or Samsung phones which are using their own chip technology. Snapdragon know mobile processors and if battery life matters, then it should be a primary factor when choosing which phone to buy.

We want to restate something. Tom’s Guide would be considered the #1 most reliable source when it comes to evaluating and testing technology. There is a real science to testing and in order to get true comparisons, no rock can be left unturned. You need consistency and you need the exact same testing conditions applied to all devices. We are extremely confident in the list that Tom’s Guide is providing.

We will update with other main publications and their Zenfone 9 battery life findings in the weeks and days to come.


Zenfone 9 size comparison vs. iPhone 13 Mini vs. Flagship Phones

Big shout out to the YouTuber The Tech Chap! This guy really did an amazing Zenfone 9 review video and we highly recommend you watch it. Part of review included Zenfone 9 size comparisons. People say that the Zenfone 9 is the best small phone out there, so just how small is it? You might be surprised!

Note: Shopping for a Zenfone 9? We have updated in-stock listings here.

The saying a picture is worth a thousand words applies to this size comparison. People will talk numbers but until you actually see the sizes of the various flagship phones beside each other, it’s almost impossible to know. You have to visualize. You have to see side-by-side comparisons to know the full story.

So take a gander at these comparisons as done by Tech Chap. We will discuss below the photos. We highly recommend you view the screenshots in full size to appreciate the comparisons properly.

So keep in mind that the Zenfone 9 is the same size as the Zenfone 8. The Apple iPhone 13 is looking to be a very similar size to the Zenfone 9. Wouldn’t you agree? We take this as a positive. You can see that the Zenfone 9 vs. iPhone 13 Mini, the size difference is quite stark. What you need to know is that when it comes to the Android slew of flagship phones, ASUS is offering up a unique size. Yes, in the Android world, the Zenfone 9 is small. However, let’s not suggest that the Zenfone 9 is small to the point of diminishing returns. It looks to be about on par with the Apple iPhone 13 main model.

The Zenfone 9 is small but it’s not a the cost of usability. It’s safe to say something as small as the iPhone 13 Mini is at the point where it’s going to limit your enjoyment of the device. You cannot say the same for the size of the Zenfone 9. ASUS seems to have found a perfect balance point. They had strict guidelines for the device width so that you can swipe with one hand.

So what do you think about these Zenfone 9 size comparisons? As expected? Shocking? What? Let us know in the comment section below please!


US gets an official Zenfone 9 release date from ASUS

Update August 10, 2022:   Global Version available from a reputable and trustworthy Amazon.com 3rd party seller with free shipping. The North American Zenfone 9 variant is not available to buy yet. It might be September before you can get a North American specific Zenfone 9 model in your hands if you live in the US. This is a legit option if you want to buy one now and live in the US. Canada shoppers are out of luck with this one, sorry. If you don’t want to wait? Buy Now Options:

Option 2: More listing where you can actually buy a Zenfone 9 now. Full details and options here.

We can appreciate that every market in the world is asking when or if they might get a Zenfone 9 release date. The Zenfone 8 was a rather limited release but things are looking very promising for other parts of the world that missed out last time. We have something for people living in the US, and this also may apply to Canada as well.

US release date: September

This, according to ASUS via their ASUS North America twitter account. Here is a screenshot to verify the information we announcing here.

Of course as with all things in life, this is likely subject to change. However, we remain positive. This is actually a really be deal if ASUS can bring the Zenfone 9 to the US and Canada in September. We always seems to remember Oct and even November by the time the Zenfone models would end up in the US market. That’s our recollection anyways.

Not to put a damper on this news, but we do monitor what’s going on with the FCC and we haven’t seen the Zenfone 9 show up yet. This means something. We’ve never seen a device launch in less than around a month after showing up at the FCC. We always say, if it’s not at the FCC yet then a release is not close. We have a week or two until we get nervous and we will start to openly question the release date schedule for North America.

It’s about time we set up our “go to” posting for all things related to ZenFone 9 pre order. We have been doing this for a few years now and we have our ear to the ground and finding out the latest and newest information. No matter what part of the world you are from, we hope to give you ZenFone 9 pre order options and where to buy.

When can I pre order the ZenFone 9?

Here is the pre order availability schedule, in order:

  1. Europe, Hong Kong, Taiwan
  2. North America, Japan, Indonesia and South America.

In select markets, pre orders for the ZenFone 9 have started up immediately following the unveiling event on July 28, 2022. Not all markets will get pre orders early. In the past the US and Canada didn’t get a new ZenFone release until September or October but let’s hope this year is earlier than past years.

What is the price of the ZenFone 9?

Update: We are hard at work trying to get the US pricing as we know a lot of our visitors are from the North America region. Multiple reviews from trusted sources are suggesting a starting price of $699 USD, however Engadget is still saying pricing for the US is yet to be determined. If ASUS brings the ZenFone 9 to the US market for $699 USD, which was the ZenFone 8 launch price, then that’s a real feat and a really aggressive (but probably necessary) move.

Here are the official prices in Euro. Please do not simply take these prices and convert to your local currency. This would no be an accurate price. Use our logic written below.

  • $699 USD / € 799 / £699.00 – 8G/128G (currently on sale from ASUS online stores in Europe and UK)
  • $749 USD / € 849 – 8G/256G (€ 879 in some markets)
  • $799 USD / € 899 / £749 – 16G/256G (€ 929 in some markets and on sale currently in UK)

We just did a price post here that goes over some of our initial feelings. We are confident in telling you that the ZenFone 9 will be more expensive that then launch price of the ZenFone 8 model with 8/256GB configuration. It’s up to you to scan local information to see what the original price was on that phone in your market. If you didn’t get a ZenFone 8 launch then it will be tricky to predict the price.

Is there a ZenFone 9 Flip model?

ASUS currently doesn’t have plans to release a new ZenFone “flip” version. It’s possible that the ZenFone Flip is EOL unfortunately. A sad day if the the iconic ASUS innovation is no more.

What are people saying about the ZenFone 9?

We always like to gauge the reaction to the new ZenFone releases based on various indicators online. Here is an early sampling. We are reading a LOT of positive comments from people who are genuinely excited about this ASUS phone and some are just learning about it now!

“One of the best small phones ever – TomsGuide.com review”

“This is strangely the most interesting phone I’ve heard announced in years.”

“Looks cute, has pretty much every conceivable flagship feature (except SD card and wireless charging), A somewhat sane pricing. Why not!”

“It has a headphone jack!”

“Okay, so, this is it, right?
My next phone.”


“It’s perfect phone with perfect size.”

“I just love this phone, nothing like it. Will be my next phone for sure”

“Phone of the year for meee”

Will the ZenFone 9 be available to buy in the US and Canada?

This is an interesting question. The ZenFone 8 had a very limited release. The US market did get an official version, which is the “B” variant along with the US warranty. That model was not available in the Canadian market however. The ASUS US online store does not ship to Canada and the ASUS Canada online store doesn’t sell the ZenFone series. In our opinion, both the US and Canada will get to buy a ZenFone 9 with proper warranty for the region along with appropriate warranty.
