Dell Latitude 13 7370 review: A stylish business-class Ultrabook

Dell clearly borrowed some key features from its popular XPS consumer line when designing its latest Latitude. Some models are finished in carbon fiber, and all Latitude 13 7370s feature Dell’s nearly borderless InfinityEdge display. But this new Ultrabook has a unique style that’s perfect for Dell’s target customer: professionals.

Lenovo Legion Slim 5 review: A gaming laptop with long battery life

The Legion Slim 5 offers powerful performance, a long-lasting battery, and a hard-to-beat price. Excellent
Lenovo Legion Slim 5 Laptop BatteryLife+Solid performance in all benchmarks The bezels around the display are slim, and a slightly larger protrusion in the center of the top bezel houses the 1080p webcam. Lenovo Legion Slim 5 Audio
The Legion Slim 5 is equipped with a pair of 2-watt speakers and comes with Nahimic audio software.
The Lenovo Legion Slim 5 didn’t dominate our gaming benchmarks, but it was at the top, or at least in the middle, in all of them. Its productivity numbers were solid, and it also received high scores for storage performance. However, thisLenovo Legion Slim 5 Laptop BatteryLife is excellent, lasting more than 7 hours per charge in our tests. That’s nearly two and a half hours more than theLegion Pro 5i laptop battery.
The Nahimic audio software allows you to adjust settings to tune the sound to your personal preferences. However, after trying out the various preset sound effects, I didn’t notice much difference, so it didn’t change my opinion on the sound quality. Like most new laptops coming out these days, the Legion Slim 5 uses a 1080p webcam, a significant improvement over the 720p cameras that have long been standard equipment.

JBL GO 4 review: Definitely worth the upgrade

JBL GO 4 Bluetooth Speaker In addition to the superficial design changes, including a wider and more comfortable tactile band, a more practical placement and distribution of control elements, the device also features a number of technical improvements. The first thing to mention is the compatibility with the JBL Portable app, through which you can make the necessary adjustments to the five-band equalizer, save battery or monitor its JBL GO 4 Bluetooth Speaker Battery charge level. The Bluetooth version has also been upgraded and features Auracast technology, allowing stereo pairing or wireless connection with multiple supported speakers in party mode. The operating time ,JBL GO 4 Bluetooth Speaker Battery  time has increased from 5 to 7 hours, and if you sacrifice frequency adjustment by turning on the PlaytimeBoost function, you can add another 120 minutes. Thanks to the high coverage that ensures dust and water resistance, the owner can remain completely calm even in the event of an accident in the pool, which also applies if he plans to carry this space-modest companion on outdoor trips in more demanding conditions. The power of the smallest of the JBL wireless speakers is 4.2 W RMS. For its size, it achieves an exceptionally rich and clear sound with the help of a 45mm or 1.75-inch driver (frequency range of 90 Hz to 20 kHz). It is powered by a 3.8V lithium-ion polymer battery with a capacity of 850 mAh, and according to the manufacturer,JBL GO 4 Bluetooth Speaker BatteryThe maximum battery life is 3 hours, with up to 7 hours of playback on a single charge (another 2 hours with PlaytimeBoost turned on). Wireless communication is provided by Bluetooth version 5.3 with A2DP V1.4 and AVRCP V1.6 profiles, while the IP 67 rating prevents the penetration of dust particles and even immersion in 1 meter of water for 30 minutes will not damage the GO 4.
When testing the signal range, I was able to exceed 100 meters in the open garden area, while in the house, only the farthest corner of the bathroom was blocked by the floor, a few doors and metal building elements. Starting from a state where it was turned off due to low JBL GO 4 Bluetooth Speaker Batterythe speaker reached 60% charge after half an hour of non-use, with maximum charging time taking a total of 1 hour and 28 minutes.

Huawei MatePad Pro 12.2 (2025) review: Frosted tandem OLED and high brightness are the highlights

Conclusion – The MatePad Pro is a powerful 12-inch tabletThe Huawei MatePad Pro 12.2 (2025) is a modern tablet that combines productivity and entertainment. Huawei’s included keyboard cover is very useful. The optional stylus uses NearLink technology, has low latency, and can detect more than 16,000 pressure levels, which makes this tablet particularly attractive to creative professionals. The display is also very accurate and extremely bright.
The PaperMatte surface makes it ideal for use on the go.Huawei MatePad Pro 12.2 (2025) /tablet battery life is also excellent, not outstanding, but still very good at more than 12 hours. While the MatePad’s daily performance is good, the Kirin T92A is slightly slower than the competition, especially when the GPU is heavily loaded. Although Wi-Fi 7 is supported, 6 GHz Wi-Fi is not supported.
Huawei MatePad Pro 12.2 (2025) Battery capacity:May be equipped with a large-capacity battery of 10,000mAh~12,000mAh (the previous generation MatePad Pro 12.6 is 10,050mAh).
 life performance: Official nominalHuawei MatePad Pro 12.2 (2025) /tablet battery life is about 10-12 hours (video playback/daily office), depending on the screen refresh rate, processor energy efficiency optimization, etc.
Camera – MatePad Pro 12.2 (2025) with 50 MP sensor Housing, functions and operation – MatePad Pro 12.2 has become lighter The resolution of the 50-megapixel main camera has been significantly improved, and the daily shooting effect is also quite good, which is very suitable for recording. Although the additional ultra-wide-angle lens is a good additional feature, the image quality is obviously poor. Zoom is digital only (up to 10x), and quality is mixed.

The Galaxy Watch 8 gets a key battery health feature that more smartwatches need

New Battery Protection feature in One UI 8 Watch keeps your Galaxy Watch 8 charged at 85% to 90% Samsung’s new Galaxy Watch 8 series introduces a “Battery Protection” feature designed to extend the device’sGalaxy Watch 8 batterylife.
The feature works by stopping charging when the battery reaches 90% and only resuming charging when the battery drops to 85%.
This prevents theGalaxy Watch 8 batteryfrom being 100% full, thus reducing stress and helping to slow long-term battery degradation.
Most people don’t upgrade their smartwatches every year, instead choosing to keep using them until something better comes along or the battery degrades. However, unlike smartphones, most smartwatches don’t offer robust battery protection features, which limits theirSmart Watch Battery Samsunglife. Fortunately, more and more smartwatch manufacturers are starting to roll out these features, with Samsung being the latest to introduce them in its new Galaxy Watch 8 series.
In previous Galaxy Watch models, there were only two options listed under the Charging section of the Settings > Battery menu: Show charging info and Auto-power on. The former controls whether the watch displays the battery level when it’s fully charged, and the latter determines whether the watch automatically powers on when connected to a charger.
While setting up my Galaxy Watch 8 Classic, however, I discovered a third new option called Battery Protection. This new feature stops charging at 90% and resumes charging at 85%. Essentially, this feature keeps the watch’s battery between 85% and 90% of its maximum capacity.
Galaxy Watch 8 batteryProtection settings on the Galaxy Watch 8This feature is important because keeping a lithium-ion battery at 100% state of charge for long periods of time can shorten its lifespan, as a high state of charge puts stress on the battery. As a result, many smartphones offer similar protections, but they typically limit charging to 80%, not 90% like the Galaxy Watch 8 does. Although 80% of the Galaxy Watch 8 battery charging limit is better for battery life, the battery capacity of smartwatches is small, so Samsung may not want to set the charging limit too high to avoid affecting the user experience. In any case, it is good to see that Samsung has finally added a meaningful Galaxy Watch 8 battery protection feature to the Galaxy Watch.

Huawei Watch 4 review: Super smart

The Huawei Watch series has always been the brand’s most sophisticated smartwatch (until the launch of the Watch Ultimate), and offers users the most advanced features of any wearable device. Visually, the Watch 4 has a slimmer design and a mirror-polished stainless steel case. The Watch 4 features a 1.5-inch, 466 x 466 resolution LTPO always-on display that is brighter and clearer than ever. The biggest change is the addition of eSIM functionality to the watch for the first time. The Huawei Watch 4 can use a separate eSIM card, or if you are a Globe user, you can use the eSIM card already in the watch, which continues the series’ impressiveHuawei Watch 4 Batterylife, Huawei promises up to 14 hours of battery life in ultra-long battery life mode and up to 8 days of battery life under normal use

This will allow you to use many of the watch’s advanced features, such as playing music and making calls, without having to carry your phone with you.

The battery capacity and battery life of Huawei Watch 4 series smartwatches (including Watch 4 and Watch 4 Pro) are as follows:

1. Battery capacity

Huawei Watch 4: built-in 536mAhHuawei Watch 4 Battery

2. Huawei Watch 4 Batterylife performance

Typical usage scenarios (turn on heart rate, blood oxygen monitoring, occasional calls, message notifications):

Watch 4: about 3 days Heavy use (frequent calls, GPS sports, eSIM independent networking): about 1-2 days.

Watch 4 will soon support payment using GCash (provided it has a built-in eSIM card) without a mobile phone connection, making it the first wearable device in India to support this feature. In addition, it has all the functions that a good smartwatch should have: it has a variety of health monitoring functions, including reading heart rate, electrocardiogram (ECG), blood oxygen saturation (SpO2), body temperature sensor, stress monitor and breathing checker. This watch has many built-in sensors, and Huawei claims that it can generate a microphysical report for users in 60 seconds.

Amazfit GTR 4 review: The king of budget smartwatches

It’s hard to justify Fitbit when the Amazfit GTR 4 looks better, lasts longer, and does far more than you’d expect. The TR 4 may not win any design awards, but for an affordable watch it looks pretty good (especially compared to previous versions). Like the Garmin and Polar watches, the GTR 4 supports turn-by-turn directions. It’s easy to import your own routes – I used Komoot and Strava. When you’re out for a run, hike, or bike ride, you can enable turn-by-turn directions. It’s also rated to 5ATM for water resistance, which means you can jump into a pool with it. I wore it in the shower and while washing dishes with no issues.

I got about 10 days on a single Amazfit GTR 4 smartwatch battery charge I’m not an ultramarathoner or triathlete, so I can’t vouch for the GPS battery estimates.And that’s just one side of the smartwatch. The GTR 4 also comes with a wealth of health and fitness features. You get in-depth sleep metrics and the ability to set a sleep schedule. It has period tracking, continuous heart rate monitoring, blood oxygen tracking, and stress tracking.
What’s impressive, however, is that the GTR 4 includes multi-band GPS – and at this price point. Multi-band GPS isn’t that common yet, and we’ve only started seeing it on fitness watches in the past year or so. In short, it utilizes both L1 and L5 satellite frequencies to provide more accurate GPS in challenging environments like cities or forests. I can’t think of another smartwatch in this price range that has multi-band GPS. Cheap smartwatches often have longer battery life than expensive ones. Usually, this is because they use dim, low-resolution screens that use less power. This isn’t the case with the GTR 4, but Amazfit claims a battery life of 7 days with heavy use (i.e. multi-band GPS, always-on display, etc.). You’ll get about 14 days with normal use. For endurance athletes, enabling multi-band GPS will get you about 25 hours of continuous use, while regular GPS will get you 44 hours. Bottom line — you’ll get more power than a flagship smartwatch.
 That being said, I was able to get about 10 days of use on a single charge. Half of that time, I had the always-on display turned off and multi-band GPS enabled at all times. During my testing, I logged about 2.5 hours of GPS activity. Some smartwatches and fitness bands useAmazfit GTR 4 Smartwatch Battery
life longer, but with moderate use and an OLED display, 10 days is great. Charging time is not great. It took me about two hours to charge from zero to 100%. This is not the worst, but it stands out as more and more wearables now support fastAmazfit GTR Smartwatch Battery
charging. I am not a fan of proprietary chargers, but again, this is a problem in the smartwatch industry.
Feature OverloadThe GTR 4 has a ton of features. Depending on your needs, it might actually have too many. If I went into every single one, this review would easily be over 2,000 words. No one has time to write that—especially since Amazfit is more than happy to list all of them on its product page. It’s exhaustive.
