Acer Liquid X2 Review and Full Specifications: Everything You Should Know

Back in 2015, most phones asked you to pick one SIM card and live with it. The Acer Liquid X2 went the other way entirely. It gave you three micro-SIM slots, a big removable battery and two 13-megapixel cameras, all in a 5.5-inch body that cost about 230 euros when it finally reached shops. In short, this was the Acer Liquid X2 for travellers with three SIM cards, heavy callers and anyone who was tired of carrying two phones just to keep work and personal numbers apart.

This Acer Liquid X2 release date and price story is worth getting straight before anything else, because the dates confuse people even now. Acer announced the phone in April 2015 at its New York launch event, alongside the Liquid Leap wearable and the Predator gaming range. It did not actually reach buyers until February 2016, which is why some listings call it a 2015 phone and others call it a 2016 phone. Both are partly right: announced in 2015, released in February 2016, and now long discontinued. As an Acer phone from that era it sits in an interesting spot, a genuine flagship attempt from a brand better known for laptops than for handsets.

This Acer Liquid X2 full specifications and review covers the screen, the processor, both 13MP cameras, the big removable battery and the triple-SIM setup, plus the honest downsides: a 720p panel on a 5.5-inch screen, Android 5.1 with no real upgrade path, and no fingerprint sensor or NFC. That question, is the Acer Liquid X2 still worth buying today, is exactly what the final verdict answers, and the short answer is that it depends entirely on what you want it for. Acer’s 2015 line-up was broad, and the same year also brought tablets, so if you want a sense of what else the brand was building at the time, How Good Is the Acer Iconia Tab 10 A3-A40? Full Review and Specifications is a useful companion read.

Acer Liquid X2 Design, Build and Display

Acer Liquid X2 dimensions weight and build quality

The Liquid X2 measures 153.3 x 78.8 x 8.5 mm and the Acer Liquid X2 weight is 166 grams, which puts it squarely in normal 2015 phablet territory. It is not a slim phone by modern standards, but it never feels like a brick either, and the weight is spread evenly across the body so it sits comfortably in one hand for calls and in two hands for typing. The Liquid X2 dimensions make it a little wider than many rivals of the time, a consequence of the 5.5-inch screen and the three SIM trays tucked under the back cover, yet the rounded edges and the slightly curved rear panel stop it feeling blocky. Liquid X2 durability is decent for an all-plastic phone: the body is plastic from edge to edge, the back cover is a metal-look plastic panel that holds firmly in place, and the whole thing survived daily use in the period without the creaks and flex that plagued cheaper plastic handsets. There is no water resistance rating, no metal frame and no glass back, so this is a practical design rather than a premium one, and that is fine. The Acer Liquid X2 design language is simple and tidy, with a clean front, a centred earpiece, the front camera and its flash up top, and the rear camera and single LED flash arranged neatly on the back.

The removable back cover and the colour choices

Pop the back cover off and you find the reason the phone is 8.5 mm thick: a removable 4,020mAh battery that blocks access to the SIM slots, so you will be taking it out more often than you might expect. The cover itself is tough to remove the first few times, which is mostly a good thing, since it means it never rattles or comes loose in a pocket. The Acer Liquid X2 black and gold colour options were the two finishes offered at launch, black for buyers who wanted something discreet and gold for buyers who wanted the phone to stand out a little. The Acer Liquid X2 colours both use the same metal-look finish on the rear panel, and the gold version in particular photographs well, even if the plastic underneath gives the game away the moment you pick it up. If you are buying second hand now, check the back cover carefully: a loose or cracked cover is the most common cosmetic fault, and a replacement cover is far harder to find than a replacement battery.

Buttons, ports and the headphone jack

Down the right edge sit the power button and the volume rocker, both plastic, both with a firm click and no wobble. The Acer Liquid X2 FM radio and headphone jack features are both present, which matters more than it sounds: the 3.5 mm jack sits on the top edge, the FM radio works with wired headphones as its antenna, and in 2015 that combination was still a genuine selling point for commuters. The Acer Liquid X2 microUSB port and data transfer speed are strictly of their time, a microUSB 2.0 port on the bottom edge, with no fast charging standard and no USB-C in sight. Charging is slow by modern standards, which is one reason the big battery matters so much, and data transfer over the cable is fine for music and photos but nobody would call it quick. There is a single loudspeaker on the back, and like most rear speakers of the era it is easy to muffle when the phone lies face up on a desk.

Acer Liquid X2 display quality and screen resolution

The Acer Liquid X2 display is a 5.5-inch IPS LCD panel with a resolution of 720 x 1280 pixels, which works out at about 267 pixels per inch. On paper that is the weakest part of the spec sheet, and on a 5.5-inch diagonal the pixels are visible if you look for them, especially in small text. In practice the Acer Liquid X2 display quality and screen resolution turn out better than the numbers suggest. The panel has good contrast and good maximum brightness for its class, colour reproduction is decently accurate, and viewing angles are wide, as you would expect from IPS. The Liquid X2 screen is perfectly readable indoors and fine for video, reading and browsing, which is what most owners used it for. The weakness shows up outside: the Acer Liquid X2 screen brightness in direct sunlight is only mediocre, and the minimum brightness is rather high, so the screen can feel too bright in a dark room at night. Sunlight legibility was the one display test where the phone clearly lagged behind its rivals, and if you spend a lot of time outdoors that is worth knowing. There is no high refresh rate here, no always-on display and no blue-light filter beyond what Android 5.1 itself offered, so judge the screen on its own 2015 terms and it holds up well enough.

Acer Liquid X2 Performance, RAM and Storage

Acer Liquid X2 MediaTek MT6753 processor benchmark

At the heart of the phone sits a MediaTek MT6753 octa-core processor with 3GB of RAM, a 28 nm chip running eight Cortex-A53 cores at 1.3 GHz with a Mali-T720MP4 graphics processor. The Acer Liquid X2 chipset is a mid-range part, not a flagship one, and the Acer Liquid X2 MediaTek MT6753 processor benchmark results from the period tell that story plainly: CPU scores were acceptable for the segment, the GPU did a decent job, and the modest 720p resolution actually helped, since the graphics chip had far fewer pixels to push than it would have on a 1080p panel. Liquid X2 performance in everyday use was smooth for the basics, calls, messaging, email, web browsing and social apps all ran without drama, and the Acer Liquid X2 performance and gaming test picture was reasonable for casual games of the era. Heavy 3D games ran, but with lower detail settings and the occasional dropped frame, and the phone could get warm during long gaming sessions. Do not expect it to run modern demanding games or recent apps well today, since the chip, the old Android version and the 3GB of memory all limit what current software will even install, let alone run smoothly.

Acer Liquid X2 3GB RAM multitasking performance

The Acer Liquid X2 3GB RAM multitasking performance was one of its genuine strengths in 2015, when many rivals in the same price bracket still shipped with 2GB. Three gigabytes meant you could keep a browser with several tabs open, switch to email, take a call and come back without the phone reloading everything from scratch. Liquid X2 RAM management was helped by the light software, since Acer kept its Android build close to stock, and the phone rarely felt starved of memory in normal use. That said, 3GB is a hard ceiling today. Modern apps are heavier, background services eat more memory, and a phone of this age will reload apps more often than you would like. If you plan to use one as a second phone for calls, messages and music, the memory is fine. If you plan to run a dozen modern apps side by side, it is not.

Acer Liquid X2 32GB storage and microSD expansion

Storage is another area where Acer was generous for the price. The Acer Liquid X2 32GB storage and microSD expansion combination gives you 32GB built in, plus a dedicated microSD slot that does not steal one of the SIM slots, which is a thoughtful touch on a triple-SIM phone. Liquid X2 storage in practice leaves a healthy amount free after the system and pre-installed apps, easily enough for a large music library, offline maps and a reasonable photo collection, and the microSD slot takes the pressure off entirely if you shoot a lot of video. There was also a cheaper 2GB RAM and 16GB storage version in some markets, so check the listing carefully if you are buying second hand: the 3GB and 32GB version is the one reviewed here and the one worth looking for. There is no adoptable storage trickery to worry about on Android 5.1, the card simply works as portable storage for media and files.

Acer Liquid X2 Cameras: Two 13MP Shooters

Rear camera and the f/1.8 lens

The rear camera is a 13-megapixel unit with autofocus, an f/1.8 lens and a single LED flash, recording video at 1080p and 30 frames per second. The Acer Liquid X2 camera quality and photo samples from the period paint a mixed picture: daylight shots are usable, with decent detail in the centre of the frame, but the overall output is barely average, with soft detail and low contrast compared with the best cameras of 2015. The Liquid X2 camera struggles most in tricky light, where highlights blow out and shadows turn muddy, and the f/1.8 aperture helps less than you might hope because the sensor and the processing behind it are modest. The Acer Liquid X2 video recording quality at 1080p is serviceable for family clips and holiday footage, with stable exposure and acceptable sound, but fine detail is soft and there is no optical stabilisation, so keep your hands steady or lean on something solid. Acer Liquid X2 video also suffers from the same low-contrast look as the stills, and the gallery app includes a photo enhancement mode called LumiFlex, which brightens images and works in other apps too, though it cannot rescue a genuinely poor shot. For a phone of this price the camera was fair, not outstanding, and buyers who cared most about photography were better served elsewhere.

Acer Liquid X2 13 megapixel front camera selfie

The front camera is where the X2 genuinely stood out. The Acer Liquid X2 13 megapixel front camera selfie setup pairs a 13MP sensor with an f/1.8 lens and its own LED flash, a combination almost nobody else offered in 2015, and it makes the phone a surprisingly good selfie machine for its era. The 13MP front camera with its own LED flash produces pleasing selfies in good light, with natural skin tones and plenty of detail, and the flash helps in dark rooms and bars, even if the light it throws is harsh and the range is short. Video calls benefit too, since the high-resolution front sensor keeps your face sharp on the other end of the call. The front camera is arguably the most memorable feature of the whole phone, and it is the reason the X2 still gets mentioned in conversations about selfie phones years later. Just remember that both cameras record memories, not masterpieces, and set your expectations to 2015 levels.

Acer Liquid X2 Battery Life and Charging

Acer Liquid X2 battery life test

The Acer Liquid X2 battery is a removable Li-Po unit rated at 4,020mAh, and it is the single most practical thing about this phone. The Acer Liquid X2 battery life test figures published when the phone was new were genuinely strong: close to 13 hours in both screen-on tests, web browsing and video playback, and an endurance rating of around 65 hours with mixed use. Voice call endurance was less impressive, and having three SIM cards inside had a substantial effect on standby drain, which is only logical, since three radios searching for signal use more power than one, but even with that penalty the phone comfortably outlasted most rivals. For a traveller juggling local SIM cards abroad, that endurance was the whole point of the phone: what good are three radios if they drain the battery by lunchtime. Acer later pushed battery size even further in the Acer Liquid Zest Plus in Review: Usability, Value for Money and Every Spec That Matters, which carried a 5,000mAh cell, but the X2 got there first in spirit, pairing a big cell with a low-resolution screen and a modest chip so the power stretched a long way.

Acer Liquid X2 removable battery and charging time

The Acer Liquid X2 removable battery and charging time story is simple: the battery comes out, and charging is slow. There is no fast charging standard on board, so a full charge from empty takes a few hours over the microUSB port, and the phone is best charged overnight. Acer Liquid X2 charging is unremarkable, but the removable battery more than makes up for it, since a spare battery in your bag is faster than any fast charger. If you buy one second hand today, this Acer Liquid X2 battery replacement guide for beginners boils down to four steps: power the phone off, pop the rear cover, lift the old battery out by its notch, and press the new one in the same way round, making sure the contacts line up before you refit the cover. Buy a battery from a reputable seller, check that it is genuinely rated at 4,020mAh, and be wary of cheap copies that claim a higher capacity than the original, since those claims are rarely true. A fresh battery is the single best upgrade you can give a second-hand X2, and it is a five-minute job with no tools.

Acer Liquid X2 Software and Everyday Features

Acer Liquid X2 Android 5.1 Lollipop software features

The phone launched with Android 5.1 Lollipop, and the Acer Liquid X2 Android 5.1 Lollipop software features are mostly stock Android with a light Acer layer on top. The Acer Liquid X2 Android experience is clean and close to what Google shipped, with Material Design throughout, lock-screen notifications, and the quick settings panel that Lollipop introduced. Acer Liquid X2 software adds a few genuinely useful touches rather than a heavy skin, and the phone feels faster for it. The interface is straightforward, the settings menus are easy to follow, and there is little bloat to remove, though a few Acer apps are pre-installed and some of them cannot be uninstalled, only disabled. One honest warning: the software is old, and old software has consequences. Many modern apps now require Android 6 or later, some banking and messaging apps will refuse to install at all, and security patches stopped years ago, so this is not a phone to use as a daily driver for sensitive accounts.

Acer Liquid X2 multi window mode and float apps

The best software additions are the ones Acer built itself. The Acer Liquid X2 multi window mode and float apps combination lets you run two apps side by side on the 5.5-inch screen, and float small apps like the calculator or a notepad over whatever else you are doing. Multi-window on a phone this size is genuinely useful for comparing prices, copying details between apps, or watching a video while you reply to a message, and Acer’s implementation was straightforward to use, a long press or a simple gesture brought it up, and the split could be adjusted by dragging the divider. Float apps borrowed ideas from Samsung and Sony at the time, and together the two features made the X2 feel more productive than most phones in its price range. The features were a hit, while some of Acer’s other additions, like its custom camera interface and its theme choices, were more of a miss, which is a fair summary of the software as a whole.

Acer Liquid X2 software updates after Android Lollipop

The Acer Liquid X2 software updates after Android Lollipop amount to very little, and buyers should know that before spending any money. The phone stayed on Android 5.1 for its whole commercial life, with no official upgrade to Marshmallow or beyond, and only minor maintenance updates along the way. That freezes the phone in 2015 in practical terms: the Google Play services layer kept some things working for a while, but the app gap grows every year and there is no official route to a newer Android version. Enthusiasts sometimes ask about custom ROMs, and while the modding community did produce unofficial builds for some MediaTek phones of this era, support for the X2 specifically was thin, and flashing one is a project for experienced users only, with a real risk of bricking the phone. For most people the honest advice is to accept Android 5.1 as part of the package, use the phone for calls, messages, music, FM radio and offline maps, and keep anything sensitive on a modern device.

Calls, sound, sensors and connectivity

Day-to-day use is where the X2’s priorities show. The Acer Liquid X2 speaker quality and call sound are solid rather than spectacular: the earpiece is clear, callers sound natural, and the loudspeaker is loud enough for speakerphone calls in a quiet room, though it distorts at maximum volume and, being on the back, is easy to muffle. Liquid X2 sound through the headphone jack is clean and perfectly fine for music and podcasts, and the FM radio is a nice bonus for anyone who still listens to broadcast radio. The Acer Liquid X2 WiFi Bluetooth and GPS connectivity package covers the basics and nothing more: Wi-Fi works on the 2.4 GHz band only, with no 5 GHz support, Bluetooth is version 4.0, and GPS with A-GPS locks on reasonably quickly outdoors. The Acer Liquid X2 no NFC and no fingerprint sensor situation is worth stating plainly, since both were becoming common in 2015 and 2016: there is no tap-to-pay, no quick unlocking with a finger, and the only lock options are PIN, pattern and password. Acer Liquid X2 sensors are limited to an accelerometer, a proximity sensor and a compass, so there is no gyroscope, no ambient light sensor and no step counter, which means auto-brightness is absent and some games and apps that need a gyroscope will not work properly. Liquid X2 connectivity on the mobile side is LTE Cat4, with download speeds up to 150 Mbps and uploads up to 50 Mbps, and HSPA at 42.2 Mbps down, which was respectable for a mid-range phone of the time.

Full Specifications of the Acer Liquid X2

The table below gathers every key figure in one place, so you can check a detail without reading the whole review again. The Acer Liquid X2 specs are those of the 3GB RAM and 32GB storage version, which is the version most buyers received and the version reviewed here. A cheaper 2GB and 16GB version existed in some markets, so if a listing shows different memory figures, that is probably why. The Acer Liquid X2 triple SIM card slots explained in plain terms: the phone takes three micro-SIM cards, all three get 2G connectivity, but only one card at a time gets 3G or 4G, and you choose which one in the settings menu, so you never need to move cards between slots to change which number has data.

How to read this spec sheet

Three numbers on this sheet matter more than the rest. The 4,020mAh battery is large for 2015 and is the reason the phone lasts so long. The 720p resolution is low for a 5.5-inch screen and is the reason text looks softer than on rivals. And the triple-SIM setup is the reason the phone exists at all, since no other reputable brand offered three SIM slots in a phone like this. Everything else, the MT6753 chip, the 3GB of RAM, the 32GB of storage and the twin 13MP cameras, is solid mid-range hardware for the period, and the spec sheet only makes sense when you read it as a whole: a practical travel phone, not a spec-sheet champion. If any figure in a second-hand listing disagrees with this table, check the exact model number, since regional versions sometimes differed in bands and in the cheaper memory configuration.

Acer Liquid X2 vs the Competition

The Acer Liquid X2 vs Acer Liquid X1 comparison is the natural starting point, since the X2 replaced the X1 in Acer’s line-up. The X1, launched in September 2014, had a larger 5.7-inch HD screen, an octa-core MediaTek MT6592 at 1.7 GHz, 2GB of RAM, a 13MP rear camera with a weak 2MP front camera, and a 2,700mAh battery on Android 4.4. The X2 is better in almost every way that matters: more RAM, more storage, a far better front camera, a much bigger battery, a newer Android version and the triple-SIM trick the X1 never had. The X1’s only real advantage was its slightly larger screen, and even that came with the same 720p resolution stretched further. If you are choosing between the two second hand, the X2 wins clearly, and it is the only one of the pair that makes sense to buy now.

The table shows the trade-off clearly. Both rivals had sharper 1080p screens and cost less, and the Redmi Note 3 had a faster Helio X10 chip, but neither could match the X2’s front camera or its triple-SIM setup, and only the Redmi Note 3 matched its battery size, without the removable cover. The Vibe K4 Note is the closest direct rival on paper, sharing the same MT6753 chip, but its smaller 3,300mAh battery and 5MP front camera leave it behind where the X2 is strongest. Liquid X2 alternatives from Acer’s own later line-up are worth a look if you want a more modern take on the same ideas: if you want the sharper screen Acer offered a year later, the Acer Liquid Jade 2 at a Glance: Review and Detailed Specifications is the one to compare, a smaller and cheaper alternative from the same family is the Acer Liquid Z6 After a Week of Use: Review, Display and Full Specs, and the bigger-screen sibling is covered in the Acer Liquid Z6 Plus Review: Key Features Tested and the Complete Specs. Each of those is a different answer to the same question the X2 asked, and none of them kept the triple-SIM trick, which tells you how unusual the X2 really was.

Pros, Cons and Who the Acer Liquid X2 Suits

Liquid X2 pros

• Triple-SIM phone with a removable 4,020mAh battery is a combination no rival offered, and the battery life to match, with close to 13 hours of screen-on use in published tests.
• Two 13MP cameras with an f/1.8 lens on both sides, plus a front flash, make it a strong selfie phone for 2015.
• Generous 3GB of RAM and 32GB of storage with a dedicated microSD slot, so memory and storage were never the bottleneck.
• Clean, near-stock Android 5.1 with useful extras like multi-window mode and float apps.
• Good screen contrast and brightness for the price, with wide viewing angles from the IPS panel.

Acer Liquid X2 cons

• 720p resolution on a 5.5-inch screen looks soft next to 1080p rivals, and sunlight legibility is mediocre.
• Camera output is barely average, with soft detail and low contrast, despite the impressive megapixel count.
• No NFC, no fingerprint sensor, no gyroscope and no 5 GHz Wi-Fi, so several features buyers expected by 2016 are missing.
• Stuck on Android 5.1 with no official upgrade, so modern apps increasingly refuse to install and security patches stopped years ago.
• Slow charging over microUSB, and the battery blocks access to the SIM slots, so swapping SIM cards means taking the battery out.

Who should buy it, and who should skip it

The X2 suits three kinds of buyer. First, travellers and dual-number users who genuinely need three SIM cards in one phone and cannot find that anywhere else. Second, collectors and fans of unusual phones, since a triple-SIM handset from a laptop brand is a curiosity with a story. Third, anyone who wants a simple second phone for calls, texts, music and FM radio, with a battery they can swap in seconds. The Acer Liquid X2 second hand price in 2026 is low, typically the price of a cheap accessory rather than a phone, so the financial risk is small, but the Liquid X2 price only makes sense if you accept the limits. Skip it if you need modern apps, mobile banking, tap-to-pay or a good camera, and skip it as a main phone for anyone who relies on their handset for work. The Acer Liquid X2 common problems and how to fix them are mostly age-related: a tired battery is fixed by a replacement cell, SIM confusion is fixed by choosing the data SIM in settings, sluggish performance is fixed by removing unused apps and keeping only a few apps installed, and app incompatibility has no real fix, since it comes from the Android version itself. If you meet those limits with open eyes, the X2 is a charming piece of 2015 hardware.

Frequently Asked Questions About the Acer Liquid X2

When was the Acer Liquid X2 released?

Acer announced the Liquid X2 in April 2015 and released it in February 2016, which is why you will see both years quoted. It launched with Android 5.1 Lollipop, was priced at about 230 euros, and is now discontinued, so any unit you find today is second hand or old stock. The February 2016 release date is the one that matters for judging its rivals, since by then 1080p screens and fingerprint sensors were already common in its price range.

Does the Acer Liquid X2 have a fingerprint sensor or NFC?

No. The phone has neither a fingerprint sensor nor NFC, so there is no fingerprint unlocking and no tap-to-pay. Locking is by PIN, pattern or password only. This was a notable omission even in 2015 and 2016, when both features were spreading fast through the mid-range, and it is one of the clearest signs that Acer spent its budget on the triple-SIM hardware and the battery instead.

Can the Acer Liquid X2 battery be replaced?

Yes, and easily. The 4,020mAh battery is removable: power the phone off, pop the rear cover, lift the battery out and press a new one in. No tools are needed and the job takes about five minutes. Buy a battery rated at 4,020mAh from a reputable seller, since cheap copies often claim more capacity than they deliver, and remember that the battery sits over the SIM slots, so you will remove it whenever you change SIM cards.

How many SIM cards does the Acer Liquid X2 take?

The Liquid X2 SIM setup takes three micro-SIM cards, which is the phone’s signature feature. All three slots support 2G, but only one slot at a time supports 3G or 4G, and you pick which one in the settings menu. That makes it ideal for combining a home number, a work number and a local travel SIM, or for keeping separate numbers for calls and for mobile data.

Is the Acer Liquid X2 still a good phone in 2026?

As a main phone, no: Android 5.1 is too old for most modern apps, the 720p screen and the MT6753 chip are far behind current hardware, and there is no NFC or fingerprint sensor. As a second phone for calls, texts, music and FM radio, or as a collector’s piece, it still has a case, thanks to the triple-SIM slots, the removable battery and the 13MP front camera. Judge it as a piece of 2015 hardware with one trick nobody else offered, and it holds up; judge it against a modern budget phone, and it does not.

Final Verdict on the Acer Liquid X2

The Liquid X2 verdict is a simple one: this was a practical, likeable phone with a single great idea, and that idea was three SIM cards in one handset with a battery big enough to feed them. Everything else about it was solid mid-range hardware for 2015, from the MT6753 chip and 3GB of RAM to the 32GB of storage and the twin 13MP cameras, and the weak points were equally clear, a soft 720p screen, an average rear camera, no NFC or fingerprint sensor, and software that never moved past Android 5.1. This Acer Liquid X2 review has tried to keep both sides in view, because the phone deserves better than nostalgia and better than dismissal: it was genuinely useful for the travellers and multi-number users it was built for, and it is still interesting today for exactly the same reason. If you want one, here is a concrete next step for today. Check the listing for the 3GB and 32GB version, confirm all three SIM slots and the removable battery are present, budget for a fresh 4,020mAh battery, and test the phone with your own SIM cards before you commit, paying attention to call quality, the front camera and the screen in daylight. If those checks pass and the price is low, you will own a small piece of phone history that still does the one job no modern phone will do for you.
