Acer beTouch E100 Review and Full Specifications: Everything You Should Know
This Acer beTouch E100 review and full specifications guide looks at a small Windows Mobile phone from a very different era of mobile design. The Acer beTouch E100, also known as the Acer C1, was a compact touch phone built for calls, messages, email and light browsing, with a 3.2-inch screen, a 2 megapixel camera, GPS and 3G data in a body that weighed only 118 grams. It was announced in October 2009 and released in the same month, at a price of about 200 euros. That timing matters, because every judgement in this guide is made against 2009 expectations, not against the phones of today. If you are looking at a used example, a boxed collector piece, or a forgotten handset in a drawer, this guide will help you decide what it can still do, what it cannot do, and what to check before you pay.

The short version is simple. The Acer beTouch E100 review picture is one of a light, pocket-sized Windows Mobile phone with a usable camera for its class, a clear if modest screen, and a removable battery. Its limits are just as clear: 256MB of RAM, a single-core 528 MHz processor, a resistive screen, and no Wi-Fi. The Acer beTouch E100 price at launch was about 200 euros, and a fair price today depends far more on condition, battery health and completeness than on that original figure. Read the sections below before you buy, and you will know exactly where this classic phone fits.
Overview: A Compact 2009 Windows Mobile Phone
An Acer beTouch E100 Windows Mobile 6.5 phone review has to start with context. In October 2009, Acer was building a broad range of Windows Mobile handsets, and the beTouch line was aimed at people who wanted messaging, email and social networking in a pocket-sized device. The E100 sat near the entry of that range. It was not the larger neoTouch, and it was not a slider with a keyboard. It offered a 3.2-inch touch screen, a 2 megapixel camera, GPS with A-GPS, Bluetooth and HSDPA data, all in a slim body of 113 x 56 x 12.8 mm. The Acer beTouch E100 release date October 2009 price story is useful for collectors and second-hand buyers: because the phone was announced and released in October 2009 at about 200 euros, a clean working example with its battery, charger and manual is worth more than a scratched unit with a tired cell, even if both carry the same model name.
The most important fact to keep in mind is the operating system. This is a Microsoft Windows Mobile 6.5 Professional phone, not a later smartphone platform, and it should be judged as a product of its own time. An Acer beTouch review of this family should be read with that shared Windows Mobile context in mind. Its software, its screen and its hardware were designed for the tasks of 2009: calls, texts, email, calendar, contacts, maps and simple media. The Acer beTouch E100 features list is long on paper, but the real experience is shaped by the small memory, the single-core chip and the resistive screen. That is the lens to use when you read the rest of this guide.
What kind of phone was the E100?
The E100 was a messaging and everyday phone first, and a media phone second. Its software was built around Windows Mobile 6.5 Professional, with Acer Home on top, Pocket Office for documents, email, calendar and contacts, and shortcuts to the services of the period. The Acer beTouch E100 Pocket Office email and calendar features cover Word, Excel and PowerPoint files, email with attachments, calendar, tasks and contacts, and synchronisation with a computer of the period. That made the E100 a sensible choice for office use in 2009, and it still works offline today for viewing old documents, even though modern email services, modern web security and modern file formats will not work as they did then. Treat the software as a closed, offline system, not as a live connected platform.
For many buyers in 2009, the appeal was practical. You could write messages on the touch screen, check a map with GPS, take a usable photo in daylight, and carry the phone in a shirt pocket without noticing its 118 gram weight. The phone did not try to be a games machine or a large-screen video player, and that focus kept its size and price in check. The Acer beTouch E100 software experience is best understood in those terms: a small, light tool for communication, with a few useful extras, rather than a device that tried to do everything.
Who is this guide for?
This guide is for three kinds of reader. The first is a collector who wants an Acer beTouch E100 discontinued classic smartphone buying guide, with the facts needed to spot a complete, working example. The second is a curious reader who wants to understand how a 2009 Windows Mobile phone worked, and how far phones have moved since then. The third is someone who has found an E100 at home and wants to know if it can still be used for calls, texts and photos, or as a spare handset. All three will find the same answer in different words: it is a piece of history that still works for basic tasks, but it is not a daily phone for modern life.
The Acer beTouch E100 also known as Acer C1 specs point is worth settling early. The Acer C1 is the same handset under a different name, so an Acer C1 review reaches the same verdict as an E100 review, and the Acer C1 price at launch was the same, because the two names refer to one phone. When you search for parts, a battery, a manual or a case, check both names, because a seller may list the phone as the C1 rather than the E100.
Design and Display
The Acer beTouch E100 design is a plain, slim touch slab, with a 3.2-inch screen taking up most of the front, a small set of keys below it, and a camera lens on the back. There is no slide-out keyboard and no large navigation wheel, because the touch screen is the main control. The Acer beTouch E100 black colour design and handling is modest but tidy: the black finish hides wear well, the silver trim around the edge gives the phone a neat, finished look, and the slim 12.8 mm depth helps it slip into a pocket. The Acer E100 design is at its best when you hold it: at 113 x 56 x 12.8 mm and 118 grams, it is narrow enough for one-handed use, and it feels light without feeling fragile.
The Acer beTouch E100 dimensions are part of its appeal for collectors. A phone of this size is easy to carry, easy to hold on a call, and easy to keep on display next to larger handsets from the same year. The back cover lifts off to reach the battery, the SIM and the microSD card, and the phone feels well put together for its price. A used example should be checked for cracks around the cover, wear on the keys, and scratches on the screen, because those are the parts that show age first.
Screen quality in daily use
The Acer beTouch E100 display is a 3.2-inch TFT panel with a resolution of 240 x 400 pixels, about 146 pixels per inch, and 65K colours. The Acer beTouch E100 3.2 inch TFT display resolution was modest even in 2009, and it shows when you open a web page or a document. Text is readable, menus are clear, and photos look pleasant at this size, but web pages need a lot of scrolling, and small text can look rough. The Acer beTouch E100 240 x 400 pixels screen quality is best judged on the tasks the phone was built for: calls, messages, calendar entries and short browsing sessions are fine, while long documents and image-heavy pages are harder work.
The Acer beTouch E100 resistive touchscreen stylus input review angle is also relevant here. The screen responds to a fingertip or a stylus, and a stylus helps a lot for small on-screen buttons, for handwriting input, and for tapping the small controls in older Windows Mobile menus. Outdoors, the TFT panel can wash out in bright light, and viewing angles are narrow, so you may need to tilt the phone to read it clearly. Indoors, it is fine for everyday use. Do not expect the bright, sharp screen of a later phone. Expect a small, practical screen that matches the rest of the hardware.
Build, buttons and handling
The body is plastic, with a plain front, call and end keys, and a small navigation area below the screen. There is no front camera, and there is no fingerprint reader, because those features did not exist on phones of this class in 2009. The phone feels solid for its weight, and the keys below the screen are easy to find by touch. On a used phone, press each key, check the screen for dead spots, and look for wear on the printed labels, because a key that does not register or a screen area that ignores touch will limit the phone far more than a scratched back cover.
Colours and size
The E100 was sold in black, and the Acer beTouch E100 dimensions weight 113 x 56 mm figures tell only part of the story. The full size is 113 x 56 x 12.8 mm, and the weight is 118 grams. That is compact enough to slip into a shirt pocket, and the narrow width helps one-handed use. Because the colour choice was so limited, condition matters more than colour: choose a clean, working example with a good battery and a responsive screen, rather than worrying about finding a different finish.
Performance and Software
The Acer beTouch E100 performance is set by its Qualcomm MSM7225 Snapdragon S1 chip and its 528 MHz ARM 11 processor. The Acer beTouch E100 Qualcomm MSM7225 Snapdragon S1 processor was a common choice for mid-range Windows Mobile phones of the period, and it was paired with 256MB of RAM and 512MB of ROM. The Acer beTouch E100 256MB RAM 512MB ROM performance picture is clear: the phone can handle calls, messages, email, calendar, contacts and light apps, but it slows down if you open several apps at once, and it is not suited to heavy multitasking or demanding games. The E100 Snapdragon S1 platform is best judged on the tasks it was built for, and on those tasks it is adequate rather than fast.
There is no dedicated graphics chip listed for this model, which fits its role as a messaging and everyday phone. Menus move at a steady pace, the touch screen keeps up with normal tapping, and the camera app opens without a long wait, but web pages with many images can take time to load, and you should close apps you are not using. The Acer beTouch E100 memory is the limit that shapes the experience most: with only 256MB of RAM, the phone rewards a light load and a tidy set of installed apps.
Windows Mobile 6.5 in practice
The Acer beTouch E100 Windows Mobile 6.5 Professional software experience is a reminder of how different phone software used to be. The home screen uses large, finger-friendly tiles and widgets, while deeper menus still use the older Windows Mobile style, with small text and stylus-friendly controls. The Acer beTouch E100 Acer Home interface customisation options let you change the layout, add shortcuts, and pick a theme, but the system underneath remains Windows Mobile 6.5, with its strengths and its quirks. The E100 Windows Mobile system is a closed platform today: it receives no updates, and modern apps and services will not run on it.
Pocket Office is the most useful part of the software for many owners. Email, calendar, contacts and documents all work offline, and the phone can still open old files and show old messages and appointments. That makes it useful as a record of the period, and as a simple offline organiser, even if it cannot serve as a connected daily phone. The Acer beTouch E100 software should be approached with that in mind: use what works offline, and do not expect it to keep up with modern accounts and security.
Memory and expandable memory
The Acer beTouch E100 memory is split between 256MB of RAM for running apps and 512MB of ROM for the system and built-in files. That is a small amount by any later standard, and it is the main reason the phone feels limited today. The Acer beTouch E100 microSD card slot expandable memory helps, because a microSD card can hold photos, music and documents, and it can be swapped without opening the whole phone. A card of a few gigabytes is more than enough for this hardware, and a larger card is unlikely to add any benefit.
To keep the phone responsive, keep the number of installed apps low, store photos and music on the card, and restart the phone from time to time. If you plan to use it as a collector piece, a clean reset and a small set of period apps will give the best experience. The Acer beTouch E100 specs in the table below list the same figures, so you can check a used example against them before you buy.
What the processor can and cannot do
On the plus side, the 528 MHz single-core chip is efficient for its time, and it works well with the small screen and the light operating system. Calls are clear, the GPS can fix a position for maps, and the camera can save a photo without a long delay. On the minus side, video playback is limited, web browsing is slow on complex pages, and there is no support for the apps and services that define a modern phone. That is not a fault in the chip. It is the gap between 2009 and today, and any honest Acer beTouch E100 specs discussion should make that gap clear.
Camera
The Acer beTouch E100 camera is a 2 megapixel rear camera, and it can save photos at up to 1600 x 1200 pixels. The Acer beTouch E100 2 megapixel rear camera review verdict is that daylight photos are usable for small prints, messages and records, with reasonable colour and detail when the light is good. In low light, photos become noisy and soft, and the camera has no flash to help indoors or at night, so the best results come from bright, even light. There is no front camera, so self-portraits and video calls of the modern kind are not part of this phone.
The beTouch E100 camera app is simple. You frame a shot on the 3.2-inch screen, tap to capture, and save the photo to internal memory or to a microSD card. The Acer beTouch E100 video recording 2MP camera samples idea is worth a note for collectors: video is basic, with low resolution by later standards, and it is best used for short clips rather than for anything you plan to watch on a large screen. Keep expectations in line with 2009 hardware, and the camera will not disappoint you.
Photo quality and limits
For a 2009 entry-level touch phone, the camera is fair rather than outstanding. It is not a match for a later phone camera, and it is a step below the 3.15 megapixel camera on the larger beTouch E200, but it is good enough for the everyday snapshots the E100 was built for. The Acer beTouch E100 vs Acer beTouch E101 comparison makes the wider family clear: the E100 and the E101 share the same 2 megapixel camera, the same screen size and the same core hardware, and the difference that matters is data, not photos. The E100 has HSDPA, while the E101 has only EDGE, so the E100 can load maps and email faster on a mobile connection, even though both phones take similar pictures.
When you test a used E100, take a photo in daylight and one indoors, check that the camera app opens and saves without a delay, and look at the saved file on a computer. A hazy lens, a camera app that crashes, or a photo that will not save will tell you more than any spec sheet. Clean the lens gently, use the microSD card for photo files, and keep the phone for what it does well: simple, daylight snapshots from a light, pocket-sized handset.
Battery and Connectivity
The Acer beTouch E100 battery is a removable Li-Ion cell rated at 1140 mAh. The Acer beTouch E100 1140mAh removable battery life test figures from the period should be read as laboratory claims, not as promises for a battery that is now many years old. A new or lightly used battery can still give a useful day of light use, while an old battery may last only a few hours. The Acer beTouch E100 standby time talk time battery picture follows the same rule: standby and talk time depend on signal strength, on how often the screen and GPS are used, and above all on the age and health of the cell. Because the battery is removable, you can carry a spare, and you can replace a tired cell without tools.
That removable design is a real advantage for collectors. The beTouch E100 battery is easy to reach under the back cover, and the same cover gives access to the SIM and microSD slots. If you buy a used phone, ask about the battery, check for swelling, and test the phone on a call before you pay. A swollen battery should be replaced and recycled safely, not used.
Connectivity and missing features
The Acer beTouch E100 connectivity covers GSM 850, 900, 1800 and 1900, with HSDPA for 3G data. The Acer beTouch E100 SIM card GSM 850 900 1800 1900 detail matters if you plan to insert a SIM: the phone uses a standard SIM of the period, and it needs a network that still supports 2G or 3G in your area. Many networks have closed those services, so check coverage before you buy for use rather than for display.
The Acer beTouch E100 HSDPA mobile internet speed comparison is the point that sets the E100 apart from its closest sibling. HSDPA gives the E100 faster mobile data than the EDGE-only E101, so email, maps and light browsing load more quickly when a 3G signal is available. It is still slow for modern web pages, and many modern sites will not load correctly on the old browser, but for the services of 2009 it was a real advantage, and it is the main reason to choose the E100 over the E101. The Acer beTouch E100 Bluetooth 2.0 GPS A-GPS features include Bluetooth 2.0 with A2DP for headsets and file transfer, GPS with A-GPS for maps, and a miniUSB 2.0 port for charging and data.
The Acer beTouch E100 no Wi-Fi missing features explained point is just as important: this model has no Wi-Fi, so you cannot connect it to a home wireless network, and you cannot use it for wireless browsing at home or in a cafe. The Acer beTouch E100 miniUSB port headphone jack limitations are worth stating plainly as well. Charging and data go through the miniUSB port, and wired audio arrangements on phones of this period were less convenient than the standard jacks that became common later, so a Bluetooth headset is often the simpler choice for calls. If you need wireless internet or simple wired audio, a modern phone is a better choice. This is one of the clearest limits of the E100, and it should be checked before any purchase for live use.
Full Specifications
The Acer beTouch E100 specs below are the full list for this model, also known as the Acer C1. An Acer beTouch specs check against the table below is the fastest way to confirm the model in hand. The Acer C1 specs are the same under either name, because the two names refer to the same handset. The Acer beTouch E100 also known as Acer C1 specs in this table are the reference to use when you compare a used example, and check the phone itself against the table, because a replaced battery, a missing stylus, or a non-original charger will not show up in a spec list.

The Acer beTouch E100 SAR value radiation safety information note above is deliberate. SAR figures vary by region and by test method, and the safest source is the label on the phone you hold and the manual that came with it, not a copied figure from another listing. The same care applies to the whole table: the core facts are stable across sources, but a used phone can differ in battery, card, charger and accessories.
Pros and Cons
The Acer beTouch E100 pros and cons are easy to sum up once you accept that this is a 2009 phone. Its strengths are the light, slim body, the HSDPA data that sets it apart from the E101, the removable battery, and the simple touch design. Its weaknesses are the small memory, the slow processor, the low-resolution resistive screen, and the lack of Wi-Fi and modern software support. Neither side is a surprise, and both sides should shape your decision.
Pros
Light and slim at 113 x 56 x 12.8 mm and 118 grams, so it fits a shirt pocket. HSDPA mobile data, faster than the EDGE-only beTouch E101. Removable 1140mAh battery that is easy to replace. 3.2-inch touch screen with stylus support for small on-screen controls. GPS with A-GPS, Bluetooth 2.0 with A2DP, and microSD expansion for photos and documents. Windows Mobile 6.5 Professional with Pocket Office for email, calendar and documents.
Cons
Only 256MB of RAM and a 528 MHz single-core processor, so multitasking is limited. Low-resolution 240 x 400 TFT screen with narrow viewing angles. No Wi-Fi, so no home wireless browsing. No front camera, no flash, and basic video recording. Old software with no modern app support and no security updates. 2G and 3G networks are closing in many areas, which limits live use. Battery life on an old cell can be far below the original claim.
Frequently Asked Questions
When was the Acer beTouch E100 released?
The Acer beTouch E100 release date was October 2009. It was announced in October 2009 and released in October 2009. The Acer beTouch E100 price was about 200 euros at launch. The phone is now discontinued, and it is also known as the Acer C1. The Acer C1 price at launch was the same, because the Acer C1 is the same handset under a different name.
Is the Acer beTouch E100 still worth buying in 2026?
The question is Acer beTouch E100 still worth buying in 2026, and the answer depends on why you want it. For a collector, for a display piece, or for a study of Windows Mobile history, a clean working example is worth buying at a modest price. For daily use as a main phone, it is not worth buying, because the software, the memory, the screen and the network support are all far behind modern needs. Buy it for what it is, not for what you wish it was.
What chipset does the Acer beTouch E100 use?
The Acer beTouch E100 uses the Qualcomm MSM7225 Snapdragon S1 chipset, with a 528 MHz ARM 11 processor. That is the correct chipset for this model, and it is the figure used in this guide and in the full specifications table above. The E100 Windows Mobile system runs on that chip, and the 256MB of RAM and 512MB of ROM work with it to handle the basic tasks of the period.
Does the Acer beTouch E100 have Wi-Fi?
No. The E100 has no Wi-Fi. It connects through GSM and HSDPA mobile data, Bluetooth 2.0, GPS with A-GPS, and a miniUSB 2.0 port. If you need wireless internet at home, a modern phone is a better choice. This is one of the clearest limits of the E100, and it should be checked before any purchase for live use.
How do I replace the battery and memory card?
Learning how to replace Acer beTouch E100 battery microSD card parts is simple. Remove the back cover, lift out the old 1140mAh battery, and fit a compatible replacement in the same position. The SIM and microSD slots sit under the same cover, so you can swap a card at the same time. Use a battery made for this model, check for swelling on the old cell, and recycle the old battery safely. If the phone will sit on display, remove the battery for long-term care.
Final Verdict
The Acer beTouch E100 is a clear, honest example of a 2009 Windows Mobile touch phone. Its light body, its HSDPA data, its removable battery and its compact size made sense in its year, and those same features make it an interesting collector piece today. Its small memory, its slow chip, its low-resolution screen and its lack of Wi-Fi make it unsuitable as a daily phone now. That contrast is the whole story of this handset.
If you find a clean example, test the touch screen, the keys, the camera, the GPS and the battery, and check that the SIM, microSD and miniUSB parts are present and working. The Acer E100 phone is worth a modest price in that condition, and it is worth far less if the screen, the battery or the touch response has failed. The Acer beTouch E100 collector guide vintage Windows Mobile phone angle is the right way to think about it: buy a piece of mobile history, keep it working, and enjoy it for what it was built to do.

Those five guides cover the closest Acer handsets from the same period, and they help place the E100 in its family. A short buyer check is useful here: touch screen, keys, camera, GPS and battery first, then accessories. A second collector note is that a boxed example with its manual and charger is rarer than a bare handset. A third honest summary is that the E100 rewards a careful buyer and disappoints anyone who expects a modern phone in an old body.
For a final note on value, the Acer E100 price today is set by condition, not by its 200 euro launch price. A working phone with a good battery and a responsive screen is a fair buy for a collector. A faulty phone is a parts donor, not a bargain. Keep that in mind, and this 2009 touch phone will give you exactly what it promises: a light, compact Windows Mobile handset, with a clear place in the history of Acer handsets.
