What Would It Take to Double a Cell Phone’s Battery Life?

The power of mobile devices could be doubled, but researchers are first focusing on improving larger smartphone batteries. How is it possible that a phone can do so many things—summon a car, order groceries, make video calls, count footsteps—and still drain its battery so quickly? The constant charging required seems outdated for such a smart device. Why hasn’t anyone made a better phone battery?


“To have a smartphone battery that lasts a week or more, you need to look for batteries with higher energy density – that’s the basic thing you’re looking for,” said Venkat Srini, a materials scientist in charge of energy storage and research Venkat Srinivasan said. Lawrence Berkeley National Laboratory’s Distributed Resources Division. Batteries are very complex objects, so it is difficult to achieve any kind of continuous improvement. “Energy density refers to the amount of energy stored within a smartphone battery. To extend the charging time of a phone or laptop battery to a week, researchers will need to double the battery’s energy density in the next few years. Recent improvements in phone batteries have allowed Energy density is increasing by about 5% to 6% per year, which means a smartphone or laptop can be used for several more hours.

Oukitel WP33 Pro has a 22,000 mAh battery and a huge speaker on the back

The new Oukitel WP33 Pro proudly defies thinness. and lightweight smartphones. It has an absolutely insane 22,000 mAh Oukitel WP33 Pro smartphone battery, which it claims is the largest phone battery ever. The phone weighs 577.5 grams and is 27.2mm thick. Now, here’s a device you’ll never forget you have in your pocket! That is, if you have reinforced pockets, because we’re not sure regular pockets can handle something like this without bursting at the seams.


The Oukitel WP33 Pro is also quite wide at 84mm, making it likely impossible for anyone (including NBA players) to hold and operate it with one hand. At least the height is within normal limits at 175.4mm. It is powered by MediaTek Dimensity 6100 + chipset paired with 8GB LPDDR4x RAM and 256GB UFS 2.2 storage. The screen is a 6.6-inch 1,080×2,408 IPS panel with a 60 Hz refresh rate and 450 nits brightness. It has Gorilla Glass 5 on top.


The main camera on the rear features a 64 MP Sony IMX686 1/1.73″ sensor with f/1.89 aperture and LED flash. You also get a 20 MP night vision camera with a Sony IMX350 1/1.78″ sensor with f/2.2 aperture Sensor and infrared fill light. Finally, there’s the 2 MP macro camera made by BYD (best known for electric cars, but appears to have branches as well). Selfies are taken care of by a 32 MP camera using Sony IMX616 sensor. The main function on the back has nothing to do with the camera, though. This is an absolutely insane 5W speaker that measures 36mm in diameter and has a maximum loudness of 136dB.


According to Oukitel’s own measurements, the iPhone 15’s speakers top out at 98dB, the sirens are around 109dB, outdoor speakers typically hit 116dB, and jet engines produce 120dB, and the WP33 Pro’s speakers are even better than that. It also features “8D immersive stereo surround” sound, because 3, 4, 5, 6 or even 7 are definitely not enough. The WP33 Pro supports 33W wired charging (taking 5 hours from 0 to 100%), as well as 18W reverse wired charging to charge other devices via its massive Oukitel smartphone battery. The phone is IP68 dust and water resistant, IP69K certified to withstand high-pressure water jets, and MIL-STD-810H certified to withstand a 1.5 m drop. The fingerprint sensor is located on the side. It runs Android 13, and you most likely won’t expect any updates.

Eurocom P7 Pro (Clevo P770ZM) Notebook Review

The 17.3-inch Eurocom P7 Pro is based on the latest 15.6-inch Clevo P750ZM design we introduced in the Eurocom P5 Pro Extreme.  As mentioned in our previous review, these systems are designed to handle LGA1150 socket desktop processors with overclocking potential. The end result is a performance level that’s higher than even the best gaming laptops currently available from Alienware, Asus, or MSI. Let’s see how far we can push this top-tier Eurocom console.

Clevo is moving away from the bulky, boxy and boring look of past models in favor of something more modern, but not too outlandish to the point of sacrificing any accessibility. Barebone manufacturers are still using heavy-duty ABS matte plastic to provide a more professional and sturdy quality compared to the aluminum solutions that other gaming laptops might use. The outer cover and palm rest are lightly rubberized to provide a more premium feel rather than just hard plastic. However, this does attract fingerprints and grease more easily. The bottom edge tapers very noticeably, making the laptop look thinner than it actually is As a result, its front edge is only 16mm thick, while its rear edge is 38mm thick.
The build quality is very good considering the size of the device. The base is sturdy and doesn’t twist or cause major warping when pressure is applied to the center of the keyboard. The hinge can reach a maximum angle of 135 degrees, so the display won’t wobble when typing. Applying pressure to the center of the cover will still cause some slight warping, as will twisting the display from side to side, but it’s mostly minor enough to not be a cause for concern. The bezels are slightly smaller, but feel thicker than the Eurocom X7’s thin plastic bezels.


Compared to other popular 17.3-inch gaming laptops, the Eurocom is thinner and smaller than the MSI GT72 and the particularly thick Asus ROG G751. Some laptops are indeed thinner, such as the Alienware 17 R2, but this Eurocom comes with a more demanding CPU and cooling system than the models listed here. In fact, the P7 Pro weights about the same as the GT72 (3.85kg vs 3.82kg), despite the obvious size difference between them. communicationWLAN comes standard with Intel 7265 supporting 802.11ac, Bluetooth 4.0, and dual-band (2×2) connectivity up to 867 Mbps. Qualcomm Killer 1525 options are also available for more gaming-centric features and optimizations. We had no issues with our Intel M .2 module when connected to our home network.

AccessoriesEurocom comes right out of the box with a quick start manual and a driver and utility CD. Also included are extra screws and some thermal paste. Carrying cases, VGA adapters and other cables are available directly from the dealer.

touchpadThe slightly redesigned touchpad (10.75 x 6.25 cm) is very sturdy, has no cursor issues and glides smoothly. Synaptics V7.5 lets users customize

Compared to competing models, the P7 Pro’s brightness and contrast are just as good. The Alienware 17 R2’s display is slightly better overall in terms of color accuracy and grayscale, and requires no calibration.  Alienware 17 R2 battery  lifePairing a 65 W CPU with a 100 W GTX 980M without Optimus will naturally result in excessive battery life. Under optimal conditions, we were able to squeeze out a little over 2.5 hours of idle time in battery saver mode at lowest brightness. Runtime will be reduced when using Wi-Fi or playing games, but only by an hour or so at most.


The removable 82 Wh  lithium-ion battery  pack has a slightly smaller capacity than competing 17.3-inch gaming models. For example, the Alienware 17 R2 has nearly 20% more Alienware 17 R2 battery power. The benefits of owning an Optimus are clear from the comparison chart below. We can easily say that the Eurocom P7 Pro is the best 17.3-inch gaming laptop in terms of raw performance and features. You won’t find a laptop anywhere else that has a standard LGA1150 slot, an MXM 3.0b slot , and PCIe x4 expansion all in one package. Its respectable CPU overclocking potential, excellent Boost performance, and customizable fan controls are just gravy on the otherwise solid Clevo platform. Tinkerers and hobbyists don’t need to look elsewhere for end-user customization and extensibility. 


Meanwhile, the new Core i7-5775C far outperforms the current mobile champion, the i7-4980HQ, in multi-core benchmarks, and its extensive overclocking headroom puts it very close to the more power-hungry Core i7-4790K.


There’s room for improvement, such as adding dedicated macro keys, additional legacy ports, and higher-capacity battery options. The 1080p display is great, but not as impressive as the rest of the notebook. TheEurocom P7 Pro’s short battery life and loud fan noise while gaming are also obvious drawbacks of this type of system. Even so, these are minor quibbles in what is an excellent, stable, and expensive gaming system. 
We can easily say that the Eurocom P7 Pro is the best 17.3-inch gaming laptop in terms of raw performance and features.

One such laptop included in the recall has caught fire, according to the US Consumer Product Safety Commission (US CPSC), but no other details were provided beyond the fact that the incident occurred in Canada. The most likely possibility is that the laptop battery overheated and caused the device to catch fire, but this is pure speculation at this time.


The culprit of the problem isn’t the devices themselves, but the Panasonic lithium-ion battery packs they use. The US Consumer Product Safety Commission said about 5,800 units are affected in the United States and 606 in Canada.


Stop using laptopAccording to their recall announcement, ” Lithium-ion battery  packs may overheat, posing burn and fire hazards to consumers.” Fujitsu has agreed to replace the   Fujitsu laptop batteries  with new ones.


Affected models include the Fujitsu Celest H720 and various LifeBook models – you can see the full list in the table at the end of the article. The recalled batteries are product numbers CP556150-03, CP579060-01 and CP629458-03. You can determine if your device is included by checking the white label on the battery of your  Fujitsu LifeBook  battery and comparing the numbers to those in the table below. Intend.


“Consumers should immediately stop using the recalled   laptop  battery  pack, turn off power to the laptop, remove the battery, and follow the instructions for a free replacement battery pack. Consumers should only use the laptop by plugging it into AC power until they receive a replacement  Fujitsu   laptop battery pack,” The US Consumer Product Safety Commission said.

DOOV V1’s specs leaked,another rotating camera phone from China

Two months after its release, new details of Nick Mobile, a collaboration between famous Chinese video website Tudou and DOOV Mobile, have finally emerged.
Recently, a new mobile phone from DOOV Battery obtained a network access license from the Ministry of Information Industry’s website. Its model number is DOOV V1. The phone comes with a rotating camera and is exactly the same design as the upcoming DOOV Ni Ke phone that was leaked some time ago, confirming that the DOOV V1 and DOOV Ni Ke are identical.


You can see that the camera design in the MIIT photo of the V1 is very similar to that of the Nickelodeon phone. Typically, the face of the phone is aligned with the camera (the V1 is 8.5mm thick). The camera can rotate 180 degrees to facilitate users to take selfies. Only Tudou phones in China can have such a design. According to the Ministry of Industry and Information Technology website, it only has 13mp, but as a phone dedicated to shooting videos and photos, it should have a better resolution. Will this be a special edition? It also features dual-color LED lights.


As for other specifications, DOOV V1 has a 1.5GHz quad processor (probably MTK MT6732), 2G RAM, 16G ROM, 5-inch high-definition screen, and supports TD-LTE, TD-SCDMA and GSM.

Coolpad Note 6 review: Good battery life but that can’t save it

Most smartphone manufacturers in India focus on the budget segment. This is where the sales are in the sub-Rs 10,000 price point segment. This is why Xiaomi, Motorola, Nokia, Honor, etc. are paying attention. Coolpad has also paid great attention to this area in the past. But it fell silent after a while last year. Perhaps it is reworking its India strategy. Now in mid-2018, the company is making another foray into the mainstream smartphone market with the launch of the Coolpad Note 6 The phone was launched last month with a starting price of Rs 8,999.

The price is for the 32GB variant and the 64GB variant will cost an additional Rs 1,000 and comes with a price tag of Rs 9,999. The Coolpad Note 6 is the successor to last year’s Coolpad Note 5, which focused on design and a good display. We reviewed the Coolpad Note 5 and found it to be one of the best-looking smartphones in its price segment. Unfortunately, that’s not the case with the Coolpad Note 6. I ‘ve been using the phone for a week, and I can say that I don’t find any wow factor in the Note 6’s design. Instead, it’s a phone you can really like. Well, it’s called boring.

Coolpad Note 6 designLook away. It’s a boring phone, even with most other phones in this price range. As mentioned, the Note 6 has a basic design. From the front, the Note 6 looks just like the older Samsung Galaxy J series models. From the back , the Note 6 looks different, yet ordinary. It has a camera on the rear and an LED flash in the far left corner. This is an all-plastic phone, but just to add some style to the device, Coolpad cut the plastic in odd patterns around the camera module. This looks weird to me, although it’s a matter of taste. If the camera performs well, this is rarely a problem.

On the front, the Coolpad Note 6 comes with a fingerprint sensor, located just below the display. Almost all phones in this price range have fingerprint sensors, and most are capable of recognizing finger touches very well. Unfortunately, that’s not the case with the Coolpad Note 6. The fingerprint sensor in this phone misread it for me multiple times and most of the time I had to enter my passcode to unlock the phone.

Coolpad Note 6 screenThe Coolpad Note 6’s design is boring. How about the monitor? Good enough? Answer: Not too bad. There’s nothing outstanding about the Coolpad Note 6’s display. There are other similarly priced phones on the market that have much better, colorful displays than the Coolpad Note 6.
The smartphone features a 5.5-inch Full HD display with a resolution of 1920 x 1080 pixels. On top of the display, the Coolpad Note 6 includes a layer of Corning Gorilla Glass 3, which is meant to protect the phone from scratches and other external damage. Coolpad should have put extra effort into the display, considering how important it is to a phone. Overall user experience.

The phone’s screen is dull. But there’s a bigger problem. I found that the display wasn’t bright enough. It’s very difficult to use your phone in bright sunlight. Even with the brightness level at maximum, I could barely see the screen. Pixel main camera and 5-megapixel secondary sensor capable of taking 120-degree wide-angle selfies. This is a handy feature for group clicking selfies. There’s also an additional fill light feature that helps you take better photos in low-light situations. While These features sound great, the actual performance doesn’t live up to the talk. In my experience, almost all selfies taken with the Coolpad Note 6 appear grainy and lack detail. This is done using two selfie cameras – the main camera and the wide -angle camera. Even in good lighting, the selfie camera is disappointing.
Coolpad Note 6 performanceThe smartphone is powered by a 1.4GHz octa-core Qualcomm Snapdragon 435 chipset and is paired with 4GB of RAM. Coolpad Note 6 comes in two models – one with 32GB internal storage and the other with 64GB storage. Overall, the Coolpad Note 6 is capable of handling day-to-day tasks, but can experience lag in certain situations. For example, it’s a bit difficult when you switch between open apps. Moving from one application to another takes a lot of time. Your phone can also slow down when too many apps are running in the background. Apps like Facebook, Instagram, WhatsApp etc. scroll very slowly. This clearly shows that Coolpad needs to work on the Note 6’s software optimization.


Overall, the Coolpad Note 6 struggles to handle multitasking. But surprisingly, the phone handles gaming well enough, although although you don’t have too many apps running in the background. The smartphone performed well while running games like Subway Surfers, Temple Run 2 , and even handled GPU-intensive games like Asphalt 8: Asphalt quite well.

The Note 6’s software is disappointing. The smartphone runs Android 7.1 Nougat and is customized with Journey UI. Android Nougat has been around for almost two years. The Coolpad Note 6 also comes with an outdated security patch (December 2017). Alas, when will Android phone companies realize that security is important? There’s no word yet on whether the Coolpad Note 6 will be upgraded to Oreo, let alone this year’s flagship version of Android, Android P. Android in the Note 6 has been heavily customized by Coolpad using Journey UI. The phone comes pre-installed with apps like UC Browser, Facebook, UC News, Prime Video, Amazon, Ola cab and more.


Coolpad Note 6 batterylifeThe battery is the best part of the Coolpad Note 6. When it launched the phone last month, Coolpad promised that the Note 6 would offer at least a full day of  Coolpad Note battery  life. After using this phone for a week, I can say that Coolpad delivers on its promises. Coolpad Note 6 comes with a large 4070mAh  Coolpad Note 6 battery  which the company claims can provide 350 hours of standby time. For me, the phone lasted close to 12 to 14 hours with rigorous usage, which is pretty good for a phone in this price range. If used properly, you will easily find that this phone has a battery life of 18 to 19 hours. Overall, I can say that the Coolpad Note 6 is an ideal choice for those who want a portable Android phone with long battery life.


Should you buy it?Before answering this question, please note this: the Coolpad Note 6 is an offline exclusive. The smartphone is currently available in over 300 retail stores in the country. So you can actually buy it, unlike most Xiaomi and Redmi phones which are rarely in stock .

Samsung Galaxy Book S review (Qualcomm 8cx): Super battery life, subpar app access

With Qualcomm hardware, Samsung delivers superior Samsung laptop battery life and 4G connectivity.  But ARM architecture means application limitations, so be careful. When it comes to portable laptops, Samsung’s Galaxy Book S definitely has the right idea. This slim clamshell laptop weighs less than a kilogram and can accommodate SIM cards for use. Mobile 4G connectivity, thanks to the Qualcomm Snapdragon 8cx platform, delivers ultra-long Galaxy Book S battery life What’s the point, without an Intel processor? not here. You may have heard of Qualcomm in Android phones before, and that’s pretty good too, but in laptops, things are a little different. This is an ARM-based platform, which means you can’t run full Windows (but Windows 10 S), so not all apps will be available.  


The question of how this will affect you is more controversial than it sounds. We like using the Galaxy Book S as a portable typewriter—in some ways it feels like a Chromebook on Windows, many of which are now being pushed into pricier markets. , if you want a laptop that costs nearly a fortune to be able to do more heavy lifting with a variety of applications, such as full Photoshop, then it might not be for you.
Our quick actionOn one hand, the Samsung Galaxy Book S is great: it’s lightweight, looks great, and lasts a long time. If you’re a busy person who wants 4G/LTE and doesn’t need access to complex apps, this is a dream – we’d have it over a similarly priced Chromebook.

For the right person, the Galaxy Book S could be a good choice. We’re just not sure how many of them exist. If that’s the case, then there are plenty of other options on the market at this price point, and a little research might lead you to buy something else (see below) – even if the  Galaxy Book S battery  life won’t be as good.

The small form factor means there aren’t many ports, but it’s very much in step with current trends. Its two USB-C ports – neither of which supports Thunderbolt – are open for peripheral use, or as charging ports. In a product this thin, we wouldn’t expect a full-size USB port – although Microsoft is still managing it in the Surface – but in today’s cloud-centric world (cutting the future), that’s no longer an issue.


There’s also a headphone jack, so you can plug in those over-ear headphones if you’re not connected via Bluetooth. Signing in is easy thanks to the fingerprint sensor on the power button. It’s fast and a bit like the Touch ID implementation on the MacBook Pro, which utilizes Windows Hello – however, this isn’t Windows Hello Face, as the 720p camera onboard here isn’t compatible with the required facial recognition.

The display itself is a TFT LCD, which might come as a bit of a surprise considering Samsung’s push for AMOLED panels in phones like the S20. The latter technology means it’s organically emissive, meaning individual pixels can emit light – better for deeper blacks and energy -saving potential, depending on what’s being displayed. As LCD panels go, though, this one has a lot to brag about: it’s bright, colorful, has decent viewing angles, and has adequate resolution (Full HD, not 2K or 4K). Our only issue was with the reflective quality of the surface, which isn’t unusual for laptops but might be the case if you’re outdoors. You are required to maintain higher brightness. And, let’s face it, this is a laptop designed for the outdoors: that’s what the 4G SIM slot is for.
Keyboard and trackpadFingerprint sensor (located in the power key)The keyboard in the Galaxy Book S reminds us of the add-on keyboards found on Microsoft Surface products. It’s down to aesthetics: from the look and feel, to the overall stiffness and lack of flexibility, it’s a well-implemented board. Software and Galaxy Book S batteryQualcomm Snapdragon 8cx processor, 8GB RAM256GB storage, microSD expandableMobile: 4G LTE (SIM slot)Wireless network: 802.11 a/b/g/n/ac42Wh  Galaxy Book S batterySo far, great. There’s a lot to like in terms of performance, too, depending on what you want to get from this laptop. See, this isn’t the first time we’ve seen Qualcomm hardware in a laptop – we got a taste of it back in 2019 with the Lenovo Yoga C630 WOS.

As we said when we talked about that machine, if you just want to use your Samsung to write documents, stream videos, and browse the web, it does a great job. In fact, it performs very well thanks to its  Galaxy Book S battery  life.
Because the Galaxy Book S lasts a long time. We played a Full HD video from YouTube at three-quarters brightness and half the sound – and even after five hours the battery was only at 40%.


All in all, you can watch around 13 hours of video on this laptop without any worries. Talk about an ideal travel companion when you want to tackle some kit.
Even under more common conditions, the  laptop battery  life here is well above your average, lasting well over a dozen hours — and that includes some non-Wi-Fi 4G LTE streaming (provided for this work With the EE SIM card, it slides easily into the slot on the underside of the device).
If you want a durable machine suitable for both desktop and mobile use, this Samsung is your dream. However, consider it only if you need to perform basic operations (word processing, Office 365, browsing, video, etc.) as Qualcomm hardware usually means compatibility issues with full-featured apps.

Amazon Fire HD 6 Review – Battery Life, Camera and Verdict Review

Amazon Fire HD 6 – Tablet Battery LifeThe  Fire HD 6 has a 3400mAh battery , a fact that Amazon itself doesn’t advertise. It’s a decent size, but a bit disappointing considering the tablet’s thickness and weight. For example, the 6-inch Huawei Ascend Mate 7 has a 4100mAh  Huawei Ascend Mate 7 battery , but is only 7.9mm thick and weighs 185g – thinner and lighter than the Fire HD 6 (of course, it costs four times as much). times).
iFixit’s teardown of the Fire HD 6 reveals that the  Amazon Fire HD 6 battery  itself weighs 60 grams, suggesting it might be a bit of a lo-fi device. Still, this seems like a bit of an odd place to cut corners.
In our looped video test, playing a 720p MP4 file at medium brightness, the Fire HD 6 lasted 10 hours and 25 minutes. This is a pretty good result.
However, as you’d expect from a system architecture that uses two power cores and two efficiency cores, games drain the  tablet’s battery  much faster. Based on our experience playing Real Racing 3, you’ll get around 3.5 to 4 hours of 3D gameplay .
Amazon says the tablet will last about eight hours, which is obviously a pretty conservative estimate given the results of our video testing.Amazon tablet battery life is very good. This feature isn’t found in many tablets under £100. 
Amazon Fire HD 6: CameraAmazon has always been friendly to the masses, adding cameras to both the front and back of the Fire HD 6. However, there is little benefit to either.
The rear camera is a very basic 2-megapixel model, while the front camera is a simple VGA camera. In a cheeky software move, the Fire HD 6 tries to trick you into believing it has an autofocus lens – it uses a touch-focused reticle. However, it’s really just a fixed-focus camera, and clicking to focus really just changes the exposure settings. It’s sneaky. We’re glad it exists, though, as it gives you great control over the metering of your shots and makes you feel like you have some control.
Image quality is generally poor. Detail levels are poor, photos are very grainy, and the Fire HD 6 simply can’t handle strong light sources, or even too much reflected light at all. The photo shows a lot of purple fringing and a lot of shine. If you have a phone released in the past few years, it probably has a better camera than this one.
There is an HDR mode, but it’s very slow and the results aren’t great.
The front-facing camera has a very low resolution, but the software at least makes good use of it. It uses facial recognition and is very good at making images appear bright when dealing with indoor lighting. Is there anything else to consider?

The Fire HD 6 is missing some features. In our opinion, the two most important features are mobile internet and GPS. This is a Wi-Fi-only tablet, and we don’t think Amazon will add a 3G/4G version to the books. That’s no surprise when this is clearly a budget tablet designed for buyers on a budget, but there’s something worth noting.
Even more disappointing for enthusiasts is the lack of GPS. You can’t use the Fire HD 6 as a live mapping tool, which is a shame because it’s semi-portable and would make a great vacation guide. Should I buy the Amazon Fire HD 6?The Amazon Fire HD 6 is a no-frills little tablet that’s easily the best tablet we’ve reviewed in its price range. The screen quality and  Amazon Fire HD 6 battery life of the Amazon Fire HD 6 tablet are both good: two elements that are often lacking in ultra-budget tablets.
As with any Fire OS tablet, you’ll want to make sure you’re willing to abide by its limitations. We think the price makes it worth the effort, but if not, consider something like the Asus ME176CX , which is now available for under £100, or the larger Tesco Hudl 2 .
For now, though, the Fire HD 6 offers something very unusual with its 6-inch bezels. In fact, it’s pretty good. We’d love it if this thing wasn’t so heavy and thick and could take advantage of the smaller footprint .
judgmentThe Amazon Fire HD 6 would be better if it were thinner and lighter, but otherwise offers a good tablet experience for not a lot of money. It’s perfect for buyers on a budget.

Affordable BLU Vivo XL4 goes official with huge notched display, massive battery

BLU Products got a bit of a head start when it decided to allow Amazon to list the Vivo XL4 on its online store without actually offering it for purchase. As we told you last month, the BLU Vivo XL4 is a new smartphone that attempts to offer some premium features at a more affordable price. First, anyone interested can purchase the BLU Vivo XL4 from Amazon for just $150. In fact, if you buy it now, it’s going to be a lot cheaper because BLU is running a sale on the Vivo XL4, so the lucky customer who’s first in line can get it for just $100, while supplies last.

Apart from its affordability, the main selling point of the BLU Vivo XL4 phone is the massive 6.2-inch HD+ display, which, as the title suggests, has a class to it. Additionally, the phone comes with a large 4,000 mAh BLU Vivo XL4 batteryand a pretty decent octa-core processor, coupled with 3GB of RAM and 32GB of expandable storage. Another plus point of BLU’s latest affordable smartphone is the dual-camera setup, if I may say so, which includes a 13-megapixel primary camera and a secondary 2-megapixel secondary camera for capturing depth of field.

Not to mention it also supports dual SIM cards and a fingerprint sensor. The main drawback is that it only works on GSM networks, so you’ll have to use it with carriers like AT&T and T-Mobile, since Sprint and Verizon are not.
