Forget all-day battery life: This $240 phone has a giant battery that could last 15 days

To everyone living outside of mainland China, Oukitel sounds like a smartphone manufacturer that you’ll forget about in a matter of minutes, but it has a growing track record of producing interesting, if unusual devices. However, forget the phone with a tiny E-Ink screen on the back, we’re interested in the K10000, a phone first teased earlier this year with a jaw-dropping 10,000mAh battery inside.

Pre-order the K10000 for $240

Nowadays, it’s not uncommon to find smartphones with at least a 2,500mAh or 3,000mAh battery pack inside, but even the largest smartphone battery packs are considerably lower in capacity than the 10,000mAh battery inside Oukitel’s upcoming smartphone. Even the Gionee Marathon M5, which includes a 6,020mAh battery, pales by comparison.

Following the teasers published before the summer, Oukitel has released the final specs for the phone, and a pre-order campaign for the device has launched through import site GearBest. Aside from the monster battery, the K10000 isn’t the highest spec device you’ll see. It has a big 5.5-inch display, but the resolution is only 720p, and the processor is a quad-core MediaTek chip running at 1GHz with 2GB of RAM. The rear camera has 13 megapixels, and the selfie cam 5 megapixels.

However, the K10000 is all about that gigantic battery. Oukitel says it’ll last for between 10 and 15 days of normal use, and has a clever reverse charge function where it can be used to power up other devices, a feature we’ve seen on Huawei devices in the past. Oukitel says it’ll charge an iPhone 6 Plus three times, and still have 10-percent power left over. If you’re worried the phone itself will take most of the day to recharge, a fast-charge system will take the battery to 100-percent in about three-and-a-half hours.

Wrapped in a steel frame, the phone runs Android 5.1 Lollipop, has 16GB of internal memory, a MicroSD card slot, and 4G LTE connectivity. Online retailer GearBest has the phone up for pre-order, where it’s priced at $240 unlocked, and shipping expected to start on January 2.

Bulkier than an Apple iPhone or Samsung Galaxy

Oukitel isn’t the first company to address the slow rate at which battery technology is advancing by packing a massive battery into a phone. The phone isn’t too thick at 9mm or heavy at 185 grams, especially when considering that it holds a 10,000mAh battery; but it’s certainly bulkier than most flagship phones. Until battery tech improves, smartphone manufacturers are limited to small batteries if they want to make slim devices.

However, that doesn’t mean companies aren’t trying to make better batteries. Back in April, scientists at Stanford University developed an aluminum battery that can charge from zero to full in as little as a minute. In addition, it was also reported in April that Google X, Google’s secret internal development team, is working on increasing battery efficiency and storage capacity. Google didn’t confirm the report, but it did mention the firm teamed up with the likes of Apple, Tesla, and others.

This app could be killing your Pixel phone’s battery life
Pixe 7a home screen.

No smartphone is perfect, but more so than almost any other Android phone, Google Pixel devices seem to find themselves in the spotlight for bugs and software issues. That reputation is being reinforced once again as numerous Pixel owners report that one particular app — specifically, the Google app — is causing significant battery drain and overheating issues.

If you look at the r/GooglePixel subreddit and Google's own Pixel Phone Help forums, you'll find numerous people complaining about their Pixel devices experiencing unusually bad battery life and/or poor thermals. These complaints have been ongoing since earlier this month, and one Pixel owner also reached out to Engadget to voice their concerns about what's happening. When looking through all these complaints, they all seem to come back to the Google app being the culprit.

All these outlandish battery life claims are getting silly
Man relaxing while holding OnePlus Nord N20 phone plugged into charging cable.

How long does the battery in your chosen device last? Whether it’s a smartphone, fitness band, smartwatch, laptop, or anything else, has it met or exceeded the claim made by the manufacturer? I’m willing to bet it hasn’t, or at least doesn’t do so on a regular basis, and that’s because many battery life figures published these days seem to be plucked out of thin air, and then a situation is constructed around it to make it work.

It's all getting rather silly, but is there anything that can be done about it?
Battery life information matters
Knowing the approximate length of time the battery lasts in our mobile device of choice is important. It informs us about whether it’s OK to skip charging if we’re short on time, if we must take a charger on a long weekend away, or if using a phone for GPS in the car will kill it before arriving at our destination.

Nokia’s ‘3-day’ phone battery struggles to last the weekend
The Nokia G11's camera module.

“Three-day battery life. A long-lasting battery and more processing power to take you through the weekend.” These are the exact words on Nokia’s website for the Nokia G11, and a serious selling point for the cheap Android phone. But is it an accurate statement? I’ve spent nearly a week with the G11 to find out, and unfortunately, it seems Nokia may be overselling the phone’s capabilities.
Three-day battery?
The claim comes with a caveat on Nokia’s website, but rather than undersell the statement, the clarification at the bottom of the page gives you even more confidence the G11’s 5,050mAh battery will make short work of a long weekend. It states:

“The three-day battery testing was conducted using a real-life usage test by HMD Global. The test included active usage of a device for five hours per day with a new battery. Usage included gaming, video streaming, calling, sending SMS, browsing, and using apps such as social media, news, navigation, and music. The test was conducted with normal device settings in a lit indoor environment. The device was left on standby overnight.”
