In the mod­ern world, it is dif­fi­cult with­out a smart­phone not only for adults, but also for chil­dren. It allows the child to always stay in touch with rel­a­tives and can replace a com­put­er dur­ing dis­tance learn­ing if the school, for exam­ple, is closed for quar­an­tine. Of course, when buy­ing a gad­get, you can opt for a reg­u­lar push-but­ton phone, which is very afford­able. How­ev­er, it will not have such a set of func­tions and capa­bil­i­ties as a smart­phone.

For clar­i­ty, let’s com­pare the char­ac­ter­is­tics of a con­ven­tion­al push-but­ton phone and an inex­pen­sive smart­phone:

	push-but­ton tele­phone	Inex­pen­sive smart­phone
Screen	1.44″ 98х66 FSTN	5.45” (960x480) IPS 60Hz
Built-in mem­o­ry	32 MB	32 GB
RAM	32 MB	2 GB
Mem­o­ry card slot	Up to 16 GB	Up to 128 GB
Main cam­era	No	5 MP
Front-cam­era	No	2 MP
Bat­tery	600 mAh	4000 mAh
CPU	Spread­trum SC6500ES	Uni­cos SC9832E
SIM cards	2 (reg­u­lar)	2 (nano SIM)
Oper­at­ing sys­tem	Not	Android 11
Wire­less inter­faces	Not	Blue­tooth, WiFi
Com­mu­ni­ca­tion stan­dard	2G	4G LTE, 3G, 2G
Bat­tery Life	About 2 weeks stand­by	Up to 48 hours with­out recharg­ing

Even the most afford­able smart­phone, unlike a reg­u­lar phone, has access to the Inter­net, a cam­era and a mem­o­ry capac­i­ty that allows you to down­load and install on it those appli­ca­tions that a child needs for study or leisure. Nev­er­the­less, before buy­ing a smart­phone for a son or daugh­ter, every par­ent asks him­self: how not to make a mis­take with the choice, if there are many man­u­fac­tur­ers and mod­els on the mar­ket?

To help you under­stand this, we present to your atten­tion a rat­ing of smart­phones that opti­mal­ly com­bine such para­me­ters as cost, device capa­bil­i­ties and its reli­a­bil­i­ty.

Editor’s Choice

Infinix HOT 12 PRO

HOT 12 PRO from Infinix is ​​a por­tal to the world of enter­tain­ment not only for chil­dren, but also for adults.

The 6.6‑inch screen with a refresh rate of 90Hz and a sam­pling rate of 180Hz is ide­al for com­fort­able gam­ing.

The “heart” of the smart­phone is a pro­duc­tive, but ener­gy-effi­cient 8‑core proces­sor Unisoc Tiger T616, it eas­i­ly per­forms every­day func­tions of the device, but also shows its best side in games.

Play­ers will also appre­ci­ate the intel­li­gent pro­cess­ing of audio and video. So, Dar-Link 2.0 allows you to accu­rate­ly posi­tion the sound in space — this improves the play­er’s ori­en­ta­tion on the ground. AVSYNC opti­mizes the image in three ways to help you suc­ceed in mul­ti­play­er games:

• Soft: High bright­ness and sharp shad­ow detail (for easy detec­tion of hid­den oppo­nents)
• clas­sic: Increased col­or sat­u­ra­tion for real­is­tic game­play
• Vibrant: Max­i­mum con­trast pic­ture to improve the dis­play of fine details that are invis­i­ble under oth­er con­di­tions

The main cam­era mod­ule is rep­re­sent­ed by a lens with a res­o­lu­tion of 50 MP and an arti­fi­cial intel­li­gence mod­ule. The max­i­mum pho­to res­o­lu­tion is 4208*3120 pix­els, the video res­o­lu­tion is 1080p@30FPS. The front cam­era with flash has a res­o­lu­tion of 8 MP. These are excel­lent indi­ca­tors for young blog­gers and fans of com­mu­ni­ca­tion in social net­works and instant mes­sen­gers.

The 5000 mAh bat­tery lasts up to 12 hours of gam­ing, 41 hours of talk time and 45 days of stand­by time. Safe Charge hard­ware pro­tec­tion tech­nol­o­gy will turn off the pow­er when the bat­tery is 100% charged. Ultra Pow­er Mode will allow the device to work an addi­tion­al 2.6 hours with a charge lev­el of 5%. The phone charges from 1 to 100% in 1.5–2 hours using a stan­dard 18W adapter.

ROM — 128 GB (expand­able up to 512 GB with a mem­o­ry card). RAM — 8 GB (expand­able up to 13 GB by using part of the per­ma­nent mem­o­ry). Face recog­ni­tion sen­sors and a fin­ger­print sen­sor work clear­ly and reli­ably pro­tect the smart­phone from strangers. The mod­el is avail­able in four col­ors: rac­ing black, elec­tric blue, neon green, halo­gen white.

Rating of the top 13 best smartphones for a child according to KP

1. Xiaomi Poco M5s

The smart­phone is suit­able for chil­dren who are fond of pho­tog­ra­phy and video shoot­ing, as the gad­get fea­tures a bright 6.43-inch AMOLED Dot­Dis­play screen with a peak bright­ness of 1100 nits and a pow­er­ful cam­era sys­tem that allows you to get the clear­est shots at any time of the day or night. Before you start shoot­ing at night, it does not hurt to study in detail the func­tions of the device for cre­at­ing pho­tos at night. It also pro­vides the abil­i­ty to take macro shots, but their qual­i­ty leaves much to be desired due to the insuf­fi­cient­ly high res­o­lu­tion of the 2 MP macro cam­era.

For video lovers, the advan­tage of this device will be the abil­i­ty to record 4K video. The gad­get has a large enough mem­o­ry for data stor­age (128 GB) and a slot for installing a MicroSD card (expands stor­age up to 1 TB). Sys­tem per­for­mance is ensured by a high-per­for­mance eight-core Medi­aTek Helio G95 proces­sor, and a capa­cious 5000 mAh bat­tery holds a charge for up to two days with the active use of a mobile assis­tant (watch­ing a video).

Man­u­fac­tur­ers have tak­en care to reduce the strain on the user’s eyes by equip­ping the smart­phone with anti-flick­er tech­nol­o­gy, read­ing mode and an ambi­ent light sen­sor that auto­mat­i­cal­ly adjusts the bright­ness of the screen.

Thanks to IP53 pro­tec­tion, the gad­get is not afraid of dust or water splash­es, and the fin­ger­print scan­ner and face unlock do not allow you to use the infor­ma­tion on the device with­out the knowl­edge of the own­er. The appear­ance of this mod­el is dis­tin­guished by a rich col­or range and an unbanal design: the back pan­el of the case is plas­tic, but tex­tured under the skin, so that scratch­es received dur­ing oper­a­tion are less notice­able on it.

2. DOOGEE N40 Pro

You won’t have to com­plain about the lack of RAM on this smart­phone, since it is 6 GB, and the built-in stor­age of 128 GB can be fur­ther expand­ed up to 256 GB by increas­ing it with a microSD card. With a dis­play res­o­lu­tion (1600x720) and aver­age bright­ness and con­trast (300 nits), the screen can­not be called one of the best, as the image qual­i­ty is slight­ly lost in direct sun­light. There is no dust and splash pro­tec­tion in the gad­get, and the res­o­lu­tion of the main cam­era is only 20 MP, which is not very good for film­ing at night. But the front mod­ule of 16 MP allows you to take high-qual­i­ty self­ies.

One of the main fea­tures of the smart­phone is a fair­ly capa­cious bat­tery (6380 mAh), the bat­tery life of which when read­ing books on the gad­get is 41 hours, and when watch­ing videos — 23 hours. In order to charge the bat­tery up to 70%, it will take only 10 min­utes (accord­ing to the man­u­fac­tur­er), as the device sup­ports fast charg­ing (24 W). The per­for­mance of the device is pro­vid­ed by the eight-core Medi­aTek Helio P60 proces­sor. There is infor­ma­tion secu­ri­ty with a fin­ger­print scan­ner and face unlock.

One of the fea­tures of the appear­ance of the smart­phone is a back cov­er that imi­tates leather, the col­or palette of which con­sists of black, green, blue and brown.

Main characteristics

Pros and cons

3.OPPO A55

Hav­ing a rather low cost, the smart­phone has all the fea­tures of expen­sive mod­els. With 4 GB of RAM and 64 GB of built-in mem­o­ry, it is pos­si­ble to expand the stor­age up to 256 GB using MicroSD. The bat­tery of the gad­get is capa­cious enough (5000 mAh) so that it can work 34 hours in talk mode, and 15 days on stand­by. The Medi­aTek Helio G35 proces­sor is respon­si­ble for the speed of the device, and a fin­ger­print scan­ner and face unlock are respon­si­ble for pro­tect­ing infor­ma­tion from strangers.

A fea­ture of this mod­el is the pres­ence of a com­pass and auto­mat­ic adjust­ment of the dis­play bright­ness up to 550 nits depend­ing on the illu­mi­na­tion. The gad­get has a Hall sen­sor that allows the smart­phone to turn on when the case is open and turn off when the case is closed with a mag­net­ic latch, as well as an accelerom­e­ter that is respon­si­ble for auto­mat­i­cal­ly rotat­ing the image on the dis­play when the device changes posi­tion. The main cam­era unit is a lit­tle incon­ve­nient, as it pro­trudes quite strong­ly, which can lead to break­age if the device is used with­out a case. But the 16 MP front cam­era pleas­es with the fact that it allows you to take high-qual­i­ty self­ies.

In addi­tion, the device sup­ports the OTG func­tion, which allows you to con­nect oth­er devices with a USB out­put to it if nec­es­sary, charges up to 100% in 2 hours and 35 min­utes using 18W fast charg­ing, and has splash pro­tec­tion.

Pros and cons

4. TCL 20B

A smart­phone from TCL is one of the most bal­anced in terms of price and qual­i­ty. It does not pro­vide fast charg­ing, but there is a good 4000 mAh bat­tery that can hold a charge in talk mode for 31 hours, and on stand­by — 28 days.

>

>

The stor­age capac­i­ty of the device is suf­fi­cient for a child to install edu­ca­tion­al appli­ca­tions or games: up to 512 GB can be added to 4 GB of RAM and 64 GB of inter­nal mem­o­ry using MicroSD. Unfor­tu­nate­ly, you can’t put two SIM cards into your smart­phone at the same time and increase the mem­o­ry, since the slot is com­bined with a SIM.

The dif­fer­ence of this device is a high-qual­i­ty 6.52-inch dis­play, made using TCL’s own tech­nol­o­gy, with a pix­el den­si­ty of 269 ppi and a high lev­el of col­or repro­duc­tion that does not lose bright­ness in sun­light. Smart­phone cam­eras allow you to take pic­tures in both nor­mal and macro mode. Pho­tos tak­en at night have good detail, and video is record­ed at 30 frames per sec­ond. The Medi­aTek Helio P22 proces­sor is respon­si­ble for the fast oper­a­tion of the device.

The man­u­fac­tur­er of the gad­get pro­vid­ed pro­tec­tion against dust and splash­es, but did not take into account that notice­able fin­ger­prints may remain on the glossy back pan­el, which some­what spoils the appear­ance of the smart­phone when used with­out a case.

Main characteristics

Pros and cons

5. Itel Vision 3

The smart­phone from Itel has 3 GB of RAM and 64 GB of inter­nal mem­o­ry, which can be expand­ed up to 128 GB using MicroSD. Also in the device set­tings there is a func­tion to add anoth­er 1 GB to the RAM from the stor­age, if nec­es­sary, to improve its per­for­mance.

The smart­phone does not pro­vide pro­tec­tion from dust and splash­es, but there is an eye pro­tec­tion mode and the abil­i­ty to change the col­ors and con­trast of the screen as you wish. The bat­tery capac­i­ty of the device is 5000 mAh, which allows it to work in stand­by mode for 23 days, and in talk mode — 28 hours. Despite the fact that this is a bud­get smart­phone, it sup­ports 18W fast charg­ing, which allows you to charge the bat­tery to 100% in 2 hours and 50 min­utes (accord­ing to the man­u­fac­tur­er).

The cam­era (8 MP) is equipped with a func­tion to sup­port arti­fi­cial intel­li­gence, which auto­mat­i­cal­ly detects the image and selects the opti­mal shoot­ing para­me­ters (for exam­ple, auto scene selec­tion). The Unison­ic SC9863A proces­sor works decent­ly when surf­ing the Inter­net, watch­ing video con­tent, using social net­works, instant mes­sen­gers, appli­ca­tions and “light” games.

Main characteristics

6. Xiaomi Redmi 9A

A fresh bud­get smart­phone with a sur­pris­ing­ly capa­cious bat­tery and excel­lent per­for­mance. Xiao­mi has long estab­lished itself as a qual­i­ty elec­tron­ics man­u­fac­tur­er at afford­able prices with a rea­son­able approach to fill­ing.

The large screen of the phone (6.53 inch­es), excel­lent mem­o­ry (32 GB), the main 13-megapix­el cam­era with arti­fi­cial intel­li­gence will def­i­nite­ly appeal to your child. A pleas­ant col­or palette of the case will give you the right to choose. It is also worth not­ing the care of the man­u­fac­tur­er to pro­tect the eyes from harm­ful blue radi­a­tion.

How to choose a smartphone for a child

Before decid­ing on the choice of a smart­phone, you should think about what tasks it is intend­ed for. It is unlike­ly that a younger stu­dent will need an expen­sive gad­get that has a huge amount of RAM, an arse­nal of cam­eras with high res­o­lu­tion, intel­li­gent frame pro­cess­ing and the fastest proces­sor.

It will be enough if with the help of the device the child will be able to make calls, access the Inter­net, com­mu­ni­cate in instant mes­sen­gers and be able to play sim­ple games on it. But old­er guys usu­al­ly have more require­ments for the device. To make it eas­i­er for you to choose the right device, let’s look at the para­me­ters that you need to pay atten­tion to before buy­ing:

CPU

The main ele­ment of a smart­phone, which is respon­si­ble for its sta­ble per­for­mance and speed, is the proces­sor. More pre­cise­ly, the Sys­tem on a Chip kit (chipset), which com­bines such basic com­po­nents as: a cen­tral proces­sor, a graph­ics accel­er­a­tor, wire­less inter­faces, an audio codec, a video decoder and oth­er com­put­ing ele­ments nec­es­sary for the gad­get to work.

Clock fre­quen­cy (from 1300 MHz), num­ber of cores (from 6), archi­tec­ture (ARM or Intel) and man­u­fac­tur­ing tech­nol­o­gy (7–8 NM and less) are the main char­ac­ter­is­tics of the chipset that you should pay atten­tion to. Mod­ern smart­phones main­ly use Qual­comm Shap­drag­on, HiSil­i­con Kiri, Medi­aTek, Unisoc and Apple proces­sors.

RAM

The smart­phone’s RAM stores the nec­es­sary infor­ma­tion for fast and sta­ble oper­a­tion of pro­grams, games and appli­ca­tions. 2–3 GB of RAM is enough for a child to com­fort­ably use the device. If you are going to install “heavy” games or appli­ca­tions, it is bet­ter to choose a device with the abil­i­ty to add GB to RAM from inter­nal stor­age or with a large amount (4–8 GB) so that the gad­get does not slow down and works with good per­for­mance.

Inner memory

An ana­logue of a hard dri­ve on a com­put­er is the inter­nal mem­o­ry of a smart­phone. It is designed to store videos, pho­tos, text doc­u­ments and oth­er user files. The oper­at­ing sys­tem and appli­ca­tions are also locat­ed there, which by default occu­py a cer­tain place and can­not be delet­ed, so it should be under­stood that when buy­ing a device, for exam­ple, with 16 GB of stor­age, you can use approx­i­mate­ly 9 to 11 GB at your dis­cre­tion.

>

>

Expandable memory

In almost all mod­ern devices, the size of inter­nal mem­o­ry is increased by installing a MicroSD card in a spe­cial slot. Its vol­ume depends on the capa­bil­i­ties of the select­ed smart­phone, some of them sup­port expan­sion of 16 GB or more. Anoth­er way to use more infor­ma­tion is the OTG func­tion. To gad­gets in which it is pro­vid­ed, you can con­nect a USB flash dri­ve or oth­er devices with a USB out­put.

Battery capacity

You should be aware that in prac­tice the actu­al bat­tery capac­i­ty may dif­fer from the nom­i­nal capac­i­ty declared by the man­u­fac­tur­er by 10–20%, and decrease over time. If you stop at buy­ing a smart­phone with the sim­plest func­tions, a val­ue from 2500 to 3000 mAh will be enough for you. When choos­ing a more advanced gad­get, it is bet­ter to look at mod­els with a more pow­er­ful bat­tery (from 4000 mAh).

The oper­at­ing time of the device with­out recharg­ing depends on many indi­ca­tors: the bright­ness and refresh rate of the screen, the use of stereo speak­ers, “heavy” games and appli­ca­tions, the chipset man­u­fac­tur­ing tech­nol­o­gy (the small­er the tran­sis­tors, the less the proces­sor heats up, whose tem­per­a­ture direct­ly affects auton­o­my), and so on. Fur­ther. The high­er the per­for­mance of the device, the more ener­gy it con­sumes.

Screen

For chil­dren of pri­ma­ry school age, it is desir­able that the screen diag­o­nal size does not exceed 5.5 inch­es, since the smart­phone should fit in the child’s hand. If you intend to use a mobile assis­tant for read­ing books, then it is bet­ter to take a larg­er copy. No less impor­tant is the image qual­i­ty on the dis­play, which is respon­si­ble for its res­o­lu­tion (the larg­er, the clear­er the pic­ture) and the matrix (IPS, AMOLED, TFT).

Con­sid­er some dif­fer­ences between IPS, AMOLED and TFT matri­ces:

The refresh rate of the screen (60Hz, 90Hz, 120Hz) is also impor­tant, as it is respon­si­ble for the smooth­ness of the ani­ma­tion of var­i­ous effects. How­ev­er, it should be not­ed that at an increased fre­quen­cy, the bat­tery dis­charges faster.

Camera

Many users have the opin­ion that the qual­i­ty of pho­to and video shoot­ing depends on the res­o­lu­tion of the smart­phone cam­era: the more megapix­els, the bet­ter. How­ev­er, this state­ment is not entire­ly true, because char­ac­ter­is­tics such as sen­sor and pix­el size, sta­bi­liza­tion, lens aper­ture, as well as addi­tion­al cam­era sen­sors and soft­ware pro­cess­ing are equal­ly impor­tant for cre­at­ing excel­lent shots.

For exam­ple, the larg­er the matrix, the more light it can catch, which means that the pic­ture will turn out clear­er. Its size is indi­cat­ed in inch­es (1/x”). In order not to get con­fused when buy­ing, it is enough to know: the clos­er the num­ber under the frac­tion is to 1”, the larg­er the sen­sor.

The aper­ture ratio of a lens also depends on the size, which is denot­ed (f/x) by the ratio of the focal length (f) and the diam­e­ter of its entrance pupil (x). The lens­es of the main cam­eras of smart­phones have aper­tures from f / 2.5 to f / 1.5. The small­er the val­ue of x, the greater the aper­ture ratio, and the bet­ter the frames.

Mod­ern devices are most often equipped with a block, in which, in addi­tion to the main one, addi­tion­al cam­era sen­sors are added. Depend­ing on the mod­el, it may include: wide-angle, tele‑, macro- and mono­chrome lens­es, a depth sen­sor.

Expert review of smartphones for children

Shares feed­back on using a smart­phone for a child, as well as rec­om­men­da­tions for choos­ing a device. Tim­o­fei MelikhovCTO of the BQ brand:

“Every school­child needs a smart­phone: thanks to it, the child is always in touch and has fast access to the Inter­net. There is no point in buy­ing too expen­sive gad­gets for chil­dren, as they can eas­i­ly lose or dam­age them.

A mobile assis­tant should be durable, have a high-qual­i­ty cam­era and a good speak­er. The eas­i­est way to deter­mine the opti­mal size of the device is to take the child to the salon, let him hold var­i­ous mod­els and see how well the device fits in his hand. You should also pay atten­tion to the size of the screen. It should be large enough (from 5.5 inch­es) so that the eyes of a small user do not get tired when work­ing.

To solve ini­tial tasks, such as self­ies, using instant mes­sen­gers and the Inter­net, a gad­get with 2–3 GB of RAM and 16–32 GB of inter­nal mem­o­ry is enough. For exam­ple, a big plus of Android smart­phones is that you can addi­tion­al­ly insert a card into them, which allows you to expand its vol­ume. The child does not need a pro­fes­sion­al cam­era in the gad­get: a res­o­lu­tion of 8–13 MP is enough for the main and 5–8 MP for the front. With these para­me­ters of the device, the 2500 mAh bat­tery will last all day.”
