With 4,000mAh battery, Energizer Energy E550LTE should keep going and going

MWC 2025
Read our complete coverage of Mobile World Congress

It might come as no surprise that the likes of the BlackBerry KeyOne, LG G6, and Huawei P10, just to name a few, have taken center stage so far at Mobile World Congress in Barcelona. Because of this, some lesser-known phones from lesser-known companies might fly under the radar, such as Energizer’s recently-announced Energy E550LTE.

Even though Energizer is mostly known for its batteries, the company has had its name on a few phones in the past, all of which feature rugged designs. The Energy E550LTE does not do much to get away from that design ethos, though that is not a bad thing — its IP68 rating means the phone is dust tight, and water-resistant to a maximum depth of just under five feet for up to 30 minutes. Furthermore, thanks to its rubberized corners, the phone can also withstand drops, though you might not want to test that on purpose.

The exterior tour continues on the front, where you will find a 5.5-inch, 1,920 x 1,080 resolution display below the 8-megapixel selfie camera. Around back, the Energy E550LTE features dual 13MP and 8MP sensors, with an LED flash module on the side and a fingerprint sensor right below the two cameras.

Under the hood, MediaTek’s 2GHz octa-core MTK6755 chipset and 4GB RAM power the phone, and though there are 64GB of native storage, no mention was made of any MicroSD card slot.

As with the company itself, however, the Energy E550LTE’s focus is on battery, and its large 4,000mAh battery looks to answer the bell. Not many smartphones include such a large power pack — only the Samsung Galaxy S7 Active and LeEco Le Pro 3 come to mind — so expect to be able to use the Energy E550LTE from sunrise through sunset and then some.

If the phone has done enough to catch your attention, the Energy E550LTE will sell for 449 euros (roughly $479) when it becomes available sometime this summer.

Baseus power banks are the best way to charge your phone after these discounts

One of the worst things about being a doomscroller isn't the information you're getting, it's the fear that your battery will die and the scrolling will have to end. This is especially true if you're stuck without power, waiting for the doctor or dentist to finally call your name, or have any other sort of emergency. But, Baseus has you covered with their excellent selection of on-the-go power banks made for your iPhone. Since they're small and fit directly to your phone's magnet charging area, you can think of them more as battery extenders than anything. Plus, if your phone's internal battery is starting to have battery trouble, a Baseus charger is a great way to avoid an annoying battery change session. The best news, however, is that they're all on sale. Here's what you can expect to see coming up:

Nothing Phone 3: A unique phone that’s not a true flagship
The Nothing Phone 3 in white

As smartphones have become extremely homogenous, companies must find unique ways to stand out from the crowd. For London-based Nothing, this has meant a singular company focus on blending smartphone features with unique designs that allow their phones to stand out in a sea of sameness.

The Nothing Phone 3 is the latest addition to a line of Nothing phones that are unique and polarizing in their design. Earlier this year, Nothing launched the Phone 3a Pro with a unique camera array, and the Phone 3 builds on this while also evolving the Nothing design language.

Plaud Note, the professional-tier AI notetaker, is 20% off for Prime Day
Four colleagues have a conversation around a Plaud Note AI notetaker.

Lately, as I've been working through stressful hospital visits with family, I've encountered something I haven't in quite awhile. As I hear doctors, nurses, and family say things, I'll be completely unable to remember them moments later. There's just too much going on all at once. Early in my career I encountered the same issue. There were just so many new facets of what I was doing entering my head all at once, from many sources, that it was impossible to keep track of it all. If only there were AI notetaking tools that have helped me through this. AI notetaking tools like Plaud Note and Plaud NotePin, which are both 20% off for Prime Day (from $159 to $127 for either device, saving you $32) and available by tapping the button below.
