We tested Galaxy Fold 7 Cover Screen vs Main Screen: Here is the difference in battery consumption
The most important upgrade is arguably the bigger cover screen, so you can now easily just use that and feel like you are using a regular phone. Previous Galaxy Folds had an extra narrow cover screen that made typing very difficulty and everything looked off on the weird tall aspect ratio. It was just not a good experience, inviting users to instead always open their phone to use the main screen.
$1120 off (53%) Pre-order the Galaxy Z Fold 7 at Samsung and grab a free storage upgrade on the 512GB model. On top of that, you can save an extra up to $1,000 with eligible device trade-ins. Alternatively, you can pre-order the phone with a $300 Samsung credit that must be used before completing your purchase. Pre-order at Samsung
Well, no more. So what if you only used this new cover screen? It's certainly not the point of the phone, but how much battery would you save if you decided to do so? We ran some tests and now we have the results, but first, let's recap the screen changes that Samsung made with the Fold 7 .
As you can see, the screens have both grown bigger and we have the aspect ratio change for the cover display.
So, to the testing table we went.
For our first test, we played the same video playlist first on the cover screen and then on the main screen. We always first carefully set the brightness levels to the same number for all devices we test (using professional equipment) to ensure equal conditions.
Translated into percentage numbers, using the cover screen instead of the main screen, you get 17% longer battery life.
For the web browsing test we ran a script that cycles through web pages and simulates scrolling behavior, much like in a regular web browsing session.
The results here were a bit surprising, considering the difference between the two was so tiny, much smaller than with the YouTube browsing test, amounting to just around 5%.
In normal conditions, meaning you don't use your phone out in the sun when the brightness gets too high, and you don't run super intensive apps or games, then there is a proven benefit of using the Cover screen to save battery life. But it's not huge.
In our tests, we saw a difference ranging from 5% all the way to around 20%, and we are sure there is some variability to those numbers. But if we average out the results, we would say that you get at least 10% longer battery life if you use the cover screen.
And honestly, that's not a huge win. And if it tells us something is that the main screen on the Fold 7 is actually quite efficient at doing its job.

New Verizon tactic might compel you to ditch your legacy plan
Carriers really want you off discontinued plans. While T-Mobile has kicked users off legacy plans without obtaining their permission, Verizon has come up with another strategy to make the old 5G Get More and 5G Play More plans less these plans let you enjoy either Apple Arcade or Google Play Pass. These subscription services let you access huge libraries of games for a monthly fee. Apple Arcade costs $6.99 per month, while Google Play Pass is $4.99/month. Verizon offered the game subscription services for free to customers on 5G Get More and 5G Play More plans, which were announced in 2021 but have been grandfathered now. As first spotted by Droid Life , Verizon has started notifying customers that the perks will soon stop being available to them. The company will discontinue them on September 22 and remove them from accounts on September 25. No more free Apple Arcade, Google Play Pass for 5G Get More and 5G Play More customers. | Image Credit - Droid Life Verizon hiked the prices on 5G Get More and 5G Play More by $4 in March, and a few months later, it's removing gaming perks. The company seemingly wants you to think that the plans are now poor value for money compared to what they offered before. It's no coincidence that Verizon sneakily slipped in a reminder that Apple Arcade is available with its newer myPlan. Customers on Verizon plans that come with six months of free Apple Arcade or Google Play Pass will begin to be charged if the promotional period ends before September 25, unless they cancel. If it ends on or after September 25, the subscription will simply be removed from their accounts. Verizon is reportedly also planning to hit customers with a series of price increases. The carrier has been losing customers due to price hikes, but that apparently hasn't deterred it from making moves that are likely to prove unpopular, such as removing loyalty discounts, which are offered to keep subscribers from switching.

This is the shocking price Apple pays for Trump's tariffs
Apple might be ready to pay big for AI companies, but it's already spending a lot on Trump's tariffs. During the company's latest earnings call, Apple CEO Tim Cook said that tariff spending could surpass $1.1 billion during the September quarter. In March 2025, during the previous earnings call, Cook predicted that Apple would spend $900 million on tariffs in the quarter that ended in June. On yesterday's call, he said that the company has spent around $800 million during the June quarter and expects a cost of over $1 billion in the current quarter, reports The Verge. That would add an extra $1.9 billion spent on tariffs in only six months. Tim Cook , CEO of Apple, July 31, 2025 President Trump's sweeping tariffs affected virtually all Apple devices sold in the US. Most of the iPhones sold in America are manufactured in India, while Macs, iPads, and Apple Watches are made in Vietnam, according to Tim Cook .Earlier this year, Trump threatened to impose a 'tariff of at least 25%' on every iPhone not built in the US. The president has long been pushing Apple to move some of its production to the US. Tim Cook was careful to clarify that the predictions might be imprecise. He stressed that 'many factors could change, including tariff rates.' Recent rumors claimed that Apple is planning to increase the price of all iPhone 17 models by $50. The company's goal would be to offset the added cost caused by tariffs. While Samsung hasn't been mentioned by President Trump, it's also being affected by tariffs, albeit not as heavily as Apple. Samsung moved the production of its Galaxy phones out of China long ago. Apple's stellar financial results are proof that tariffs and the related price increases are unlikely to affect the company. Given how long the iPhone's price has remained practically unchanged, I don't think a $50 increase would scandalize anyone. Unless tariffs spiral completely out of control, Apple should be fine. The company sells tens of millions of iPhones per quarter, so the modest increase wouldn't only offset the $2 billion bill but also turn it into a profit gain. That's why I wouldn't worry about Apple.
