Infinix is an underdog phone make that ’s slowly earn momentum in develop Nation . It offer a variety show of low - spec and midrange phones with agio designs and features at astoundingly low monetary value . That continues with the new midrange series , the Infinix Note 40 , which packs some strange perquisite , most notably frictionless charging .
The series ’ top - of - the - crinkle Note 40 Pro+ is crammed with feature you would n’t otherwise find on other sub-$300 telephone set . Among them is a 120Hz curve AMOLED exhibit with an in - exhibit fingermark scanner , build - in AI feature , dual speakers tuned by JBL , a super - slim visibility with a vegan leather conclusion and gold accents , and wildly firm 100 - W wired charging .

But one feature that instantaneously stick out as unusual is its support for wireless charging , which has antecedently been limited to more premium phone . Much more exciting is the technology baked into these phones that allows charging even in extreme temperatures and prevents overheating in almost every case .
Let’s talk wired charging first
The Infinix Note 40 Pro+ supports wired charging at up to 100W via a battery charger included in the corner . The high charging rate is certainly appealing for a $ 300 phone , but not unique . It is peculiarly not a significant feat for Infinix , which has already achievedinsanely fast wired charging amphetamine — 260W , to be exact — on a prototype , as well as180W on a commercially usable sound .
But despite its ho-hum speeds than preexist siblings , the new Note 40 Pro+ approaches shoot differently . It fundamentally gives you ultimate restraint over charging by countenance you choose from one of the three charging mode — Hyper , Smart , and Low Temp — when you plug in the 100W charger .
The Hyper mode draw rein the full potential of the 100W charging , which can , harmonize to Infinix , file 50 % of the 4,600mAh shelling on the Note 40 Pro+ in less than 10 minutes . For a full charge , the Hyper mode take roughly 35 minutes . This variety of fabulously libertine charging is desirable , specially when you realize just proceedings before you have to head out that the speech sound is play on low electric battery . With just a few bit of charging , you could achieve several hours ’ worth of charge .
But superfast charging and frequent charging cycles/second can also stress any battery and lead in faster abasement — which is also why Infinix consciously choose a slower commit hurrying on the Note 40 Pro+ . On top of that , tremendous heat is yield inside the phone if you use the phone while charging it , particularly at high charging rate in the range of 100W. Heating , in addition to the preexisting emphasis of fast charging , can top to quick battery wearing .
To reduce the shock that fast charging has on the barrage fire ’s health , Infinix adds a “ bright ” way , which manipulates bear down speeds intelligently to keep a uniform flow of charge into the battery at a nearly steady potential . This reduce the impact on the battery animation with some manageable step-down in the charging hurrying .
The third modality , Low Temp , insure the phone ’s temperature does not increase while charging . This not only ensures a retentive battery life when you ’re not in a flush , but also averts stroke such as batteries igniting . Based on your charging habits , you could countersink the Smart or Low Temp mode as the default from the phone ’s options .
For other intensive scenarios like gaming , the sound also has a passthrough mode . It plainly keeps the earpiece awake and pauses charging after a certain percentage to prevent heating and any deterioration in performance .
A special chip to lower temperatures
The appoint speeds on the Note 40 Pro+ are managed by aspecial “ Cheetah X1 ” chipset . This silicon chip is disjoined from the MediaTek Dimensity 7020 chipset that drives the Note 40 Pro+ and is developed in - house by Infinix to optimise charging speeds and keep temperature from rising .
The X1 chip has two main modules . The first one ensures the most optimal charging amphetamine are delivered for dissimilar wired or wireless bear down scenarios while temperature are kept under control . The second one ensures that charging is done safely . These step apply both when using the charger included in the loge and using third - party chargers .
When using a third - party GaN battery charger instead of the one bundle with the phone , the charging f number is limited to 40W. While this is well slow than the 100W charging you get with the origin charger , it still seems reasonable compared to other phone trade name that offer breakneck burden speeds , but confine support for undefendable touchstone like USB - PD to 15W to 18W. The biggest disadvantage of using a non - Infinix charger is that you do n’t get the option to choose between the Smart and Low Temp modes .
Wireless charging across the board
Infinix has already defend fast radio charging with other earpiece . Last twelvemonth , it demonstrate a validation of conception with 110W libertine tuner charging and after introduced50W wireless charge on a phonethat you may buy . It even has a prototype for aphone that charge up wirelessly without any physical contact . So , slower 20W wireless charging on the Note 40 Pro+ does n’t initially sound very impressive . That is , until you learn that all four sound in the Note 40 series — priced between $ 200 and $ 300 — get wireless charging as standard .
While slower charging has its obvious disadvantage , its benefits lie in convenience . The ultrafast wireless tear technology works on a very specific communications protocol and specific chargers . These charges are not particularly portable ; they are rather bulky because they ask a larger surface area and a built - in cool off mechanics — like a rooter — to keep the striking Earth’s surface from beat too hot .
In comparing , Infinix ’s Note 40 phone charge wirelessly off a slender and sleek puck . you may nonchalantly bewilder it in your air pocket or backpack without worrying about the weight it will add . The company has chosen a magnetically attaching mechanics for the hockey puck that ’s identical to Apple ’s MagSafe , and the accessory ’s official name , “ MagPad , ” further cements its inspiration from Apple .
The hockey puck ’s charging upper is trammel to 15W — even though the Note 40 Pro+ and the other speech sound in the serial publication have wireless charging at 20W , a mismatch that Infinix should have worked out . It is , however , a easing to learn that the Robin Goodfellow is included within the box , at least on the most expensive model in the series , although the actual availability might vary with neighborhood .
The telephone set ’s magnetic pull is not inviolable enough to keep the puck prepare for good , but Infinix includes a flimsy showcase with the earpiece to solve that . The case has a orbitual ring on the back , alike to MagSafe subject for the iPhone .
Besides better the magnetic attractive feature between the speech sound and wireless charger , the gang also allow the speech sound to be used with almost any Apple MagSafe - compatible accessory , such as , as shown in the image below .
In addition to the rouse pad included with the Note 40 Pro+ , Infinix has also announced a 3,000mAh power camber with wired and wireless charge capabilities . The fragile and clear power bank attaches seamlessly to the phone without add bulk or obstructing usability .
The Infinix Note 40 Pro+ matter 212 gram ( 7.48 ounces ) with the included case , while the power bank adds another 85 gm ( 3 ounces ) . Besides some occasional heating system at the infrastructure of the power bank , it does not impact the phone ’s ergonomics or make it inconvenient to practice .
It is definitely a utile accessory if you have plans to outride outdoors or forth from power sockets for prolonged period . Notably , the power banking concern is sold separately , but Infinix has n’t revealed its exact price . Besides Infinix ’s phone , it can also charge any other phone or accessary with Qi charge support ( smartwatches turn out ) .
Lastly , the Infinix Note 40 series also supports wireless charging at up to 5W , which means you could use the phone to charge add-on such as wireless earbuds . In theory , these features really ameliorate the serviceableness of the Note 40 Pro+ ( and other phones in the serial publication ) . For the literal performance , I assess these claim for different charging scenario .
What about real-world testing?
To evaluate the Note 40 Pro+ ’s charge up artistry , I melt a serial of tests and found actual public presentation befitting Infinix ’s claim . When charging in the wired Hyper mode , the earpiece ’s barrage go away from 5 % to 45 % in the first 10 min and charged completely in less than 35 minutes . In the Smart modal value , the consign speed was dull at 55 bit for the earpiece to charge amply . When using a third - party charger with USB - PD , the consign duration increases to slightly over an hour .
However , it was not the charging speeds that I was queer about , but rather , how well the phone control passion generated during these school term . At an ambient temperature of some 27 degree Celsius ( 80 degrees Fahrenheit ) , the temperature of the phone ’s back rose to a uttermost of 38 degrees Celsius ( 100 degree Fahrenheit ) when turn on at full gun and just 31 point Celsius ( 88 degrees Fahrenheit ) when charging in the saucy mode . I record these temperatures using aUSB - C thermal camera accouterment for Android phonesthat I reviewed a few month ago .
When power was add wirelessly to the Infinix Note 40 Pro+ , the charging rate was much slow . Using the 15W MagCharge puck that was included , the earpiece took over two hours to rouse in full . The phone take much longer to charge using the slight MagCharge power bank ( sold separately ) due to its output being limited to 7.5W.
Again , the slow saddle speed is not what I was implicated about ; it was the high temperature yield as a byproduct of galvanic inductance , which is the phenomenon used for wireless charging . I was amazed to observe that the temperatures stay well under the time value that the earphone meet when charge using the wired connection . Only the bottom part of the power bank breached 40 degrees Celsius ( 104 point Fahrenheit ) , which made the earphone slightly uncomfortable to operate with the power camber attached .
At no degree did the phone itself palpate uncomfortably raging to bear — while using either the puck or the business leader bank . It was jolly commodious to employ while charging with the charismatic hockey puck . The same also go for to times when the phone was used to charge a duet of earbuds using the rearward wireless rush feature film .
Overall , the Note 40 Pro+ indorse up the mark ’s claims about ease and flexibility in all weather and scenarios .
Infinix aids Apple’s wireless charging vision
While launch its first iPhones with wireless charging — the iPhone 8 and iPhone X — Apple projected a time to come where every flat surface , from kitchen counter to table in restaurants and airports , would serve as wireless chargers . Although this visual modality did n’t materialize into world , Apple recalibrated campaign toward a more personal and convenient form of wireless charging withMagSafe . With this , Apple successfully achieve something that Android speech sound brands that had offered wireless charging on phone long before Apple could n’t : it built an entire ecosystem of accessories for the iPhone where it did n’t have to rely on other blade .
This initiated a campaign where add-on manufacturing business proactively made accouterment , especially MagSafe - compatible sheath , for Android phone . But radio charging itself hasremained limited to expensive phones — which be at least $ 500 .
Infinix ’s opening move to add wireless charging to sub-$300 telephone set reignites hopes for the feature ’s achiever — just as Apple imagined . Even though the inspiration Infinix draws from Apple is evident , the implementation on low-priced sound is good for the fluid phone industry in general , especially in the developing nations where Infinix mainly sells . It ’s apparent that Infinix does not compete with Apple — it impart to make the latter ’s vision where wireless charging is omnipresent and easily accessible .
For wireless charging to succeed , more brand must abide by suit and add up it to midrange phones . Motorola ’s conclusion to do that with the2024 Moto G Power 5Gis a welcome addition , even though it fall behind Infinix ’s effectuation of a cheaper MagSafe - like ecosystem .
