    • And now it's time for an epic comparison compendium: lined up for their mugshots are the Galaxy S5, Galaxy S5 Mini, and iPhone 5s.

    • It looks like Samsung was going for a Goldilocks appeal with this "just right" sized phone.

    • The S5 and its mini clone appear to be identical in form, just different in scale. For the number crunchers:

    • The Galaxy S5 measures in at 142 x 72 x 7.9 mm.

    • The Galaxy S5 Mini shrinks to 131.1 x 64.8 x 9.1 mm.

    • Quick subtraction shows that the Mini shaved off 10.9 mm in height and 7.2 mm in width, but added 1.2 mm in thickness. The question remains: does this minor change in size make a major difference in repairability?

    • Twist and flick: the rear cover is easily removed. This is a major bonus for repairability, and we're happy to see Samsung keep this design for simple battery replacement.

    • Looks like the Galaxy S5 Mini packs the same dust/water-resistant seal found in the Galaxy S5.

    • Spot the difference! When Samsung's wizards minimized the Galaxy S5, the SIM and microSD card slots migrated from their duplex to two individual units along the left edge of the battery compartment.

    • The microSD card slot earns the S5 mini a pat on the back. Expandable storage means you won't be needing an expansion spell to make room for your cat (or rat) photos.

    • The S5 Mini's battery must be installed by the user before firing up for the first time. We pop it in—and then claw it back out for some analysis.

    • Our initial analysis says it's smaller than the battery from our Galaxy S5, but we flip them over to make sure.

    • Yep, it's smaller.

    • The Galaxy S5 Mini's lithium-ion battery is rated at 2100 mAh, 3.85 V, and 8.09 Wh.

    • That's a 25% decrease in capacity from the Galaxy S5's 2800 mAh battery.

    • Then again, the iPhone 5S's diminutive battery clocks in at just 1440 mAh.

    • Capacity is one thing; how you use it is another. Will the Mini's smaller screen and slower processor make up for the lower capacity battery?

    • When we disassembled the S5 Mini's big brother, we ran into a confusing opening procedure that only cleared up as we got deeper into the device.

    • This time, thanks to an unchanged configuration and our Galaxy S5 repair manual, we aren't fooled twice. In order to open the front you've got to use the secret back door.

    • Ahh, the beauty of repair documentation.

    • Dun-dun... Dun-dun... The jaws of our iOpener hunt for adhesive in this mini-morsel.

    • While we wait for our Oscar nod, we'll just note that this terrifying scene reflects the all-too-common use of adhesive in our favorite devices. Just like we found in its full-sized friend, this sticky situation doesn't bode well for repair.

    • All of the knowledge and experience in the world isn't enough to make us enjoy this opening procedure. It's the same picking, prying, pain-in-the-pants process as in the Galaxy S5—nasty adhesive included.

    • With the home button cable released from the rear, the display folds up on its data cable, allowing us to safely disconnect everything and get the display off.

    • On the back of the display, home button still attached, we find a few points of interest:

    • Cypress CYTMA545 TrueTouch Multi-Touch All-Points Touchscreen Controller

    • 1200T E45H2 Finger Scanner Controller

    • The display assembly is manufactured by Samsung and is labeled as AMS447BS01.

    • Next we turn our screwdriver to the interior midframe.

    • In this case, having two midframes complicates the repair process. In order to replace any of the internal components, you must heat and pry the display assembly off, and then separate the two slabs of midframe.

    • Samsung has made our life a little easier by placing the daughterboard connector on top of the motherboard, enabling us to remove the daughterboard without the motherboard's approval removal.

    • After removing the daughterboard, we spy an extra antenna interconnect cable that wasn't present in our Galaxy S5 teardown unit.

    • We suspect this is for the Band 7 antenna (for European coverage). The green coax cable connects to the standard WCDMA and LTE bands, but Band 7 is LTE-only, and operates at 2.5 GHz — so it's a separate antenna for better antenna performance.

    • People all around the world ask us how to remove a motherboard. Well world, this is how you remove a motherboard from a Samsung Galaxy S5 Mini with a precision screwdriver.

    • We make it look easy, but never forget: In Soviet Russia, board removes you!

    • The fabled double pry only comes around once an age, and appears only to the worthy. Our skilled teardown engineer removes both cameras with one fell swoop of an opening tool.

    • Upon further inspection, we discover the 2.1 MP front-facing camera is labeled as G800F R02 1425, and the 8.0 MP rear-facing camera is labeled as DGE18402.

    • These cameras don't seem to be an inherited trait. After a quick search of the interwebs yielded no results as to their manufacturers, we decided we'd crowdsource our homework. Any takers?

    • After a little convincing, we get the SIM and microSD card tray assembly to leave its place on the motherboard.

    • Even though Samsung really poured on the glue here, the assembly was fairly easy to remove.

    • What sort of chips can we find on this bite-sized motherboard? Let's check 'em out:

    • Samsung K3QF5F50MM 1.5 GB DRAM, with the 1.4 GHz quad-core Exynos 3 Quad layered underneath. We hear the base band modem is also integrated into the apps processor, a first for a Galaxy phone sold outside of Korea.

    • Time for Science with iFixit! Today, let's learn about Envelope Tracking.

    • First developed in the 1930s to improve efficiency of high-power AM radio transmitters, Envelope Tracking is the continual monitoring and tuning of the power amplifier to match the power needed for the transmission, reducing wasteful excess energy supplied to the radio.

    • To simplify: less wasted power for longer battery life and cooler operation. More cat videos and a more comfortable pocket can be yours thanks to this technology.

    • Our Euro Mini is sporting an R2 Semiconductor R2AA217C Envelope Tracking Modulator, controlling the TriQuint TQP9059S Power Amplifier.

    • Of the few phones that support Envelope Tracking, this is the first we've seen that isn't powered by a Qualcomm chip.

    • Like an onion parfait, this phone is made up of layers. Just when we thought we were done, the external midframe has yet more doors for us to peel up.

    • Doors number two and three are shut by some powerful adhesive, but upon opening they reveal spring contacts and some button cables. Unfortunately, the buttons themselves remain firmly sequestered.

    • After peeling the button cables up from their adhesive, they pop out of their button caves.

    • The plastic button covers remain stubbornly in place. The mechanical button on the cable is the bit most likely to fail, but is easy enough to replace. However, you may have to live with scuffed exterior buttons if you drop your S5 Mini.

    • Samsung Galaxy S5 Mini Repairability Score: 5 out of 10 (10 is easiest to repair).

    • The battery is incredibly easy to remove and replace.

    • The display is now one of the first components out, making its replacement a little faster. However, it is held in with a significant amount of adhesive and requires very careful and persistent prying, as well as a considerable amount of heat to remove without cracking the glass or cutting cables.

    • Once you get the device open, several components are modular and fairly easy to replace, such as the cameras, headphone jack, vibrator motor, and speakers.

    • Replacing anything other than the battery requires first removing the display, risking extra damage on the way to a repair.

Step 14. the blue one, S3FWRN, is Samsung's NFC Controller chip. while the full name may be S3FWRN5 http://certification.nfc-forum.org/node/... --- Frank Chen, FMSH

Thanks Frank -- we appreciate the heads-up!

Miroslav Djuric -

Does it use the bad and customer misleading PenTile-RGBG display type?

https://en.wikipedia.org/wiki/PenTile_ma...: "Thus the RG-BG scheme creates a color display with one third fewer subpixels than a traditional RGB-RGB scheme"

hrbzer - crwdns2934203:0crwdne2934203:0

Can you tell whether the two pins in the upper left battery corner (just above the microSD slot) are intended for wireless charging? They seem a little too close to each other. Allegedly, Samsung support stated they indeed are meant for QI charging, others claim it would only be for the S-view cover. At least one of them has electrical contact to the battery.

Philman - crwdns2934203:0crwdne2934203:0

Hello,

In step five, under the cover there are two round connectors, in my mini s5, when removing the cover of the connector is the left-desoldou (only on your right side) and is now only soldier left side.

After loading a new screen and assemble everything, I found that the phone has poor GSM network signal and sometimes is without sign.

The fact that this pin can be desoldered having the cause? Or this connector has no relationship with the GSM signal.

Thanks
