Galaxy Z Fold 7 Battery and Charging: What to expect
The Galaxy Z Fold 7 is expected to debut in summer 2025 alongside the Z Flip 7, continuing Samsung's tradition of unveiling its latest foldables mid-year.
While the Fold series is known for offering unmatched multitasking in a smartphone form factor, battery life and charging speeds have never been its strongest suit. So what does the upcoming Z Fold 7 bring to the table in this area?
The Galaxy Z Fold 6 offered solid, but not class-leading battery life in our tests. It scored an estimate battery life of 5 hours and 33 minutes, with individual scores:
12h 42m in web browsing (vs. 9h 22m on the Z Fold 5)
7h 1m in video streaming (vs. 6h 30m on the Z Fold 5 )
) 10h 30m in 3D gaming (vs. 9h 27m on the Z Fold 5 )
The overall battery life score of the current generation did increase to 5h 33m, up from 4h 41m on the Z Fold 5 — an 18% improvement. These gains were attributed to the Snapdragon 8 Gen 3's better efficiency and improved thermal management.With the Z Fold 7 expected to use the new Snapdragon 8 Elite, battery efficiency could improve slightly once again. Qualcomm's new chipsets are known to deliver better performance-per-watt ratios, so paired with Samsung's display and software optimizations, users could see an improvement of up to an hour in mixed usage.However, don't expect a massive leap unless Samsung surprises us with stacked battery tech or other unexpected enhancements.
Samsung has consistently stuck with a 4,400 mAh battery for its last few Fold models. While sufficient for most daily needs, it lags behind some rivals like the OPPO Find N5 and Huawei Mate XT Ultimate Design, vivo X Fold 3 Pro, which use larger batteries. Unfortunately, there are no credible leaks suggesting that Samsung will increase the Z Fold 7 's charging speed. That likely means it will stick with:
25W wired charging
15W wireless charging
4.5W reverse wireless charging
This is unchanged from the Galaxy Z Fold 6 and lags behind other foldable phones offering that offer 66W, 80W, or even 100W charging from companies like Vivo, Huawei, Oppo and more. With Samsung's 25W Super Fast Charging, you can expect the Z Fold 7 to reach almost 50% in 30 minutes and 100% in about 75–85 minutes. At least those were the speeds that we got during our Galaxy Z Fold 6 review, which ranked 94th among recent phones for wired charging speed.
Wireless charging isn't much better: the Z Fold 6 reached only 13% in 30 minutes and took 3 hours and 19 minutes to fully charge at 15W, placing it 30th for wireless charging performance.
While this is good enough for overnight top-ups or a quick splash of juice during the day, it's not ideal for users who expect fast and sufficient top ups via a wireless charger. Yes. The Galaxy Z Fold 7 is expected to support 15W wireless charging.It will likely be compatible with Samsung's own wireless chargers as well as third-party options that support the Qi standard. However, you won't get the full 15W unless you use Samsung's official Wireless Charger Duo or Wireless Charger Stand.
Expect slower speeds (around 10W or less) with generic Qi-certified chargers.
Yes. Reverse wireless charging, or Wireless PowerShare as Samsung calls it, will likely return.
It can be used to charge smaller accessories like Galaxy Buds or a Galaxy Watch by placing them on the back of the Z Fold 7 . The power output is expected to remain capped at 4.5W. The Galaxy Z Fold 7 will likely use a standard USB Power Delivery (PD) PPS charger with a USB-C to USB-C cable. Samsung does not typically include a charger in the box, so you'll need to purchase one separately if you don't already own a compatible unit.Samsung, like Apple and Google, sticks closely to the USB PD standard. This means you can safely use high-quality third-party chargers from Anker, Ugreen, or Baseus and still get near-max charging speeds.That's unlike other brands such as Motorola and Xiaomi, which have a custom implementation of USB PD + PPS that can request non-standard current levels. However, without the original charger, these phones fall back to lower charging speeds.Honor, Huawei, Oppo, Vivo, and OnePlus all use their own charging protocols too. Without the brand-specific charger and 6A cable, charging speeds fall back to 18–45W.
With Samsung, you don't need to worry about any of that. Any good USB PD PPS charger should work fine.

TSMC expected to charge $45,000 for silicon wafers used to produce 1.4nm chips by 2028
Next year we should start to see flagship smartphones move from using application processors (AP) made with the 3nm process node to those made at 2nm. This will result in the use of smaller Gate-All-Around (GAA) transistors allowing more of them to fit inside an AP. Using vertical nanosheets stacked horizontally, GAA transistors surround the channel on all four sides reducing current leakage, improving the drive current, and enhancing the performance and energy efficiency of these SoCs. Silicon wafers for 2nm production cost $30,000 which is a high price to pay for the underlying substrate on which chips are built in layers. Getting manufacturers to pay $30,000 for each wafer is hard enough; TSMC started accepting orders for 2nm chips on April 1st. But the price of silicon wafers is about to get even more prohibitive. According to China Times , when TSMC moves to its 1.4nm Angstrom process node, silicon wafer prices will rise 50% to a whopping $45,000 per wafer. We probably won't see TSMC churning out 1.4nm components until 2028 at the earliest and at $45K, only TSMC's most well-heeled customers will be able to afford it. Luckily for the world's largest foundry, some of its largest customers might not think twice about shelling out such a sum for a silicon wafer. The firms include Apple, Nvidia, AMD, and Broadcom. It is interesting to see that Apple typically values the performance of the iPhone above other aspects of the device. For example, even though Apple is well behind Google and Samsung in AI, the company made sure it was among the first to pay the higher wafer prices when TSMC started producing 3nm chips. TSMC's 2nm timeline is probably behind Apple's decision to use the foundry's 3rd generation 3nm process node (N3P) on this year's iPhone 17 line expected to be unveiled in September. Apple will probably be among the first to pay $30,000 for 2nm production. The A20 and A20 Pro APs powering the iPhone 18 series could be the first 2nm chipsets found inside the iPhone. When the time comes for TSMC to schedule 1.4nm production in a few years, you can be sure that Apple will pay the $45,000 price for silicon wafers. It might do so begrudgingly, but it will pay the higher price to keep the iPhone's performance ahead of the rest of the pack. The Snapdragon 8 Elite 2 AP powering the Galaxy S26 Ultra will also be produced using TSMC's third generation 3nm chipset. The same process node will be used by MediaTek for its Dimensity 9500 AP.

Nothing Phone (3) and Nothing Headphone (1) colors and prices leak
Nothing is unveiling its first-ever proper flagship device, the Phone (3), in July, and today its colorways and prices have purportedly been outed by a tipster over on X. According to this source, the Nothing Phone (3) will come in black and white, and will start at $799 with 12GB of RAM and 256GB of storage. It will go up to $899 with 16GB of RAM and 512GB of storage. Nothing Phone (3a) Pro The base price is similar to what Nothing CEO Carl Pei teased a while back - £800. However, it's interesting to see this leak referencing US dollar pricing - we have to wonder, does this mean the Phone (3) will be fully launching in the US, not just as part of a developer beta program? That's still a mystery, as are most things regarding this device. What we do know is that it won't have Nothing's trademark Glyph interface on the back, though this may just get upgraded to a customizable dot-matrix display, if rumors prove to be correct. Nothing is also working on its first-ever pair of over-ear headphones, and these will allegedly be called Nothing Headphone (1). They will be offered in black and white with a release date of September 30 and a price of $299. Source
