Buying a best battery case for your iPhone 7 Plus is a smart choice, especially if you’re a heavy user and there are no wires and outlets available.
A larger capacity battery case, say 10000mah, would help at least triple your iPhone 7 Plus battery life, and you can use your phone for 2 or 3 days without rushing to find an outlet , even if you play games a lot and watch online videos all day.

Buying Guide – Top 7 Things You Need to Know for a Best iPhone 7 Plus Battery Case
Lets cut to the chase:
1. Larger Battery Capacity Means Longer Life and Bigger Size
A larger battery capacity case will definitely store more juice and offer longer extended life to your iPhone 7 Plus.
The iPhone 7 Plus built-in battery has the 2900mAh capacity. In theory, a 10000mAh battery case will recharge a dead iPhone 7 Plus fully for 3 to 4 times, and 8500mAh for 2 to 3 times.
However, the larger battery capacity of the case, the bigger size, and the heavier phone.
For example, a 10000mAh battery case pack for iPhone 7 Plus may weight 1.5 lbs and add 1.2 inches (3cm) to your phone.
If you’re a heavy user and need longer extended battery life in your daily work, an iPhone 7 Plus battery case with 10000mAh or 8500mAh would meet your requirement. The thing that bear mentioning is that you can’t expect it to be a slim or ultra slim case.
2. iPhone 7 Plus Battery Case with Lighting Port/Headphone Jack
Some iPhone 7 Plus battery cases add a lighting charging port so you can use your headphone to listen to music while charging your phone with the battery case. Lonlif is the iPhone 7 Plus battery case with a lightning port added.
Some battery cases do add the Bluetooth 3.5mm audio headphone jack feature for your iPhone 7 Plus, but only a few.
If this is your must-have, do read the introduction carefully to ensure the case you’re going to buy has this feature.
3. Charging Speed Is Slow, But Not That Slow
The charging for a battery case to your iPhone 7 Plus is slower than the normal wired charging. But a high quality iPhone 7 Plus battery case won’t take a whole day to charge the phone.
We’ve got some feedback from customers that the battery cases they used took around 8 hours to get the phone fully charged. That’s extremely “slow”.
What’s the normal charging speed for a best iPhone 7 Plus battery charger case?
In our test, 3 to 4 hours.
If you are playing games or running many apps that drain battery fast, such as GPS, it would take longer time to get your phone fully charged.
4. iPhone 7 Plus Battery Case with Belt Clip
Some of you may prefer an iPhone 7 Plus battery case with belt clip. But few battery cases come with the belt clip or holster. If you really need one, you should buy it separately. Most belt clips are universal-style and work with all battery cases.
5. Overheating Would Ruin Your Phone
Having a built-in system to control temperature during charging is the must-have feature for a best iPhone 7 Plus battery case. And the materials that are used to make the base would determine the ability of heat dissipation, and the better ability of heat dissipation, the less chance of overheating.
Always remember, choose the battery case for iPhone 7 Plus made with aluminum alloy, aluminium magnesium alloy, or all aluminum materials. Those are good for heat dissipation.
6. Extra Chin Is Not a Must
Some iPhone 7 Plus battery cases use an MFi Apple certified chip, and this will add an extra length to the phone (we call it a chin of the iPhone).
But the MFi Apple certified chip is not a must for a battery case.
In fact, charging does not necessarily have MFi to work with, same with CarPlay, playing iPod music (A2DP), answering phones via Bluetooth (HPF), etc.
7. Functions to Add
The major job of an iPhone 7 Plus battery case is to charge your phone wirelessly and add anti-scratches for your daily usage.
Many manufacturers would add some functions to the battery case, like extended storage, data syncing, different bumpers to customize the look, etc.
If you prefer a battery case for your iPhone 7 Plus with these functions, read carefully all the product information offered by the sellers.

Lonlif
Lonlif battery case pack is equipped with a lithium polymer rechargeable battery chip, 5500mAh, which can recharge an iPhone 7 Plus for 2 times from 10% to 80% (or more).
It’s slim, sturdy, and durable. It feels very good in hand.
Unlike Mophie battery cases which start automatically charging, this battery pack needs you to press the power button on the back for about 3 seconds to start charging. I think this is a better design. It allows you to charge your phone whenever you want. And once your phone gets fully, it will stop automatically. Off cause, you can turn off the charging whenever just by pressing the power button again.
This battery case for iPhone 7 Plus has a lightning port so you can use your wired headphones without removing the case. This also allows data syncing – you can sync the phone to your computer without taking off the case.
Charging is fast. It took around 2 hours and 52 minutes to charge our iPhone 7 Plus from 14% to 85% in our test. We turned on Airplane Mode to get it faster.
This battery case does not feature Qi wireless charging, and it supports only USB cable charging. For better performance, it’s suggested to use the original cable that your iPhone 7 Plus comes with and a wall adapter (5V/1A). You can charge the case separately or charge both the case and the phone at the same time.
We suffer no overheating issues till now.
Wrap-up
If you prefer a slim battery case for your iPhone 7 Plus, not heavy and bulky, this one is a superior option. It has all key features that a battery case should have and all the features are 4+ stars in rating.
Gixvdcu
The 8500mAh lithium polymer rechargeable battery is the superiority of Gixvdcu battery case for iPhone 7 Plus. According to the manufacturer, 8500mAh adds extra standby 190 hours, 18.5 hours for talk time, 12.5 hours for watching video, 15 hours for web browsing, and 12 hours for gaming.
In our test, this Gixvdcu iPhone 7 Plus battery case recharged the phone for 3 times from 11% to 85%.
And charging speed is quite quick. From 11% to 70%, it only took 2 hours and 14 minutes, and it’s a bit slower from 70% to 85%.
This extended batter cover features a lightning port so you can sync data to a computer without taking off the case. But lightning ear phones are not supported. You can only use your Bluetooth headphones to listen to music during charging.
The biggest downside is obvious. It’s too big and heavy. To be honest, when we received the battery pack, we didn’t notice it’s a brick. It looked not that bulky at first glance. But after we slip it onto the phone, well, the phone looks very fat.
It would take some time for you to get used to it. But once you do, you will love it.
Wrap-up
You have to sacrifice something if you prefer a larger battery capacity. Bigger size and the added weight would not be a problem once you get used to it. Gixvdcu 8500mAh battery case is a superior option for iPhone 7 Plus, especially when you are travelling or on camping trips.
Swaller
Swaller 5500mAh battery case for iPhone 7 Plus is another slim and light-weight case. It offers enough extended battery life to your iPhone for a whole day, and adds no extended length & no excessive weight.
In our test, it recharged an iPhone 7 Plus for 2 times from 11% to 85%. If you use it to recharge your iPhone from dead to 100%, you would get one recharge and there may be about 40% juice left in the battery case.
This iPhone 7 Plus battery case is the few ones that support lightning port headphones, 3.5mm headphones, and Bluetooth earphones, which is a pro that most people like.
If the lightning port music or the traditional 3.5mm headphone way is a must-have feature to you, buy this case.
Wrap-up
This iPhone 7 Plus battery case is a perfect put-it-into-pocket option, slim, sturdy and durable. It has all features you need. 5500mAh is not that much but enough for a whole day even if you’re a heavy user. The slim design would add more convenience to your daily life.
Xooparc
Xooparc battery case for iPhone 7 Plus features an 8500mAh lithium polymer battery chip, and if you need a larger capacity, this case is an excellent choice.
We got 3 recharges for the iPhone 7 Plus, 2 of which were from 0 to 100%, and 1 from 13% to 100%. Good option for travelling and camping for days.
Charging is fast too, taking only 2 hours and 42 minutes from 0 to 100%.
We love the design of this battery case. It has 3 color options to choose from, and all of them are beautiful, smooth, sturdy, and you can feel durable when holding it in hands.
This iPhone 7 Plus battery case is the first one in our test that has no heating ( in fact, it’s kind of cold) during charging. The manufacturer said it could even work under extreme temperature conditions and it featured a built-in shut down mechanism system to protect any damage.
It’s bulky, though. It weighs almost as much as your iPhone 7 Plus. Another downside is that this case is not compatible with iPhone lightning port headphones or traditional 3.5mm headphones. If you want to listen to music while charging, you need to use Bluetooth headphones.
Wrap-up
We would give 4.5 stars to this iPhone 7 Plus battery case. It’s worth every penny. The reason why it would not be a 5-star battery case is the bulky design, which we think is the trade off the larger battery capacity.
Yacikos
Yacikos battery case for iPhone 7 Plus is similar to Gixvdcu and Xooparc – with a 8500mAh lithium polymer battery chip, fast charging, only Bluetooth headphones supported, and bulky.
The thing we love most about this case is that it protects the iPhone very well. We dropped the phone several times and the case held it perfectly.
The lightning connector of the case is very sensitive. And if you need to remove the case, be sure you’re gentle enough to unplug the connector.
Wrap-up
It’s another good choice if you want an 8500mAh larger battery capacity case for your iPhone 7 Plus.
Trianium
Trianium iPhone 7 Plus battery case is an ultra slim option. It gives your phone a natural look.
The 4200mAh battery capacity offers enough longer life to your phone for a whole day. In our test, it recharged the iPhone 7 Plus from 0 to 100% and had 40% juice left. And the whole process only took 3 hours and 08 minutes, which is very fast.
Unlike others that need forces to remove, this case is super easy to take on and off. I think this is because it’s slim enough.
3.5mm headphone jack headphones and lightning port headphones are not supported. You can only use Bluetooth headphones and Apple Airpod earphones.
One thing you need to know is that this iPhone 7 Plus battery case has a chin, which does add a little length to the phone. But it’s not a con, since it’s slim enough.
Wrap-up
If you want to add extra battery life to your phone for a whole day (and a whole night) without plugging in a wire, and prefer a slim case that won’t add much weight, this is a perfect battery case for your iPhone 7 Plus.
