Digging deeper we found less well known apps such as Battery HD, Avast Battery, and Battery all showing similar ratios of happy users to unhappy ones. It certainly seems in the vast majority of cases employing one of these apps on your phone will provide improved power management for your handset. The idea of RAM optimisers is to keep your phone memory from getting filled up, and therefore prevent the kind of lag you can sometimes experience when you open, use or move between various apps. Depending on the version of Android you’re running, and the manufacturer skin on top (with Samsung’s TouchWiz being a regular problem in this area), some lag is almost inevitable, but RAM optimisers aim to minimise the drag factor these things create.

Again you can manually control some of the factors involved with lag. Resetting your device regularly can often help, as does keeping an eye on when updates are installed for certain apps, so any change in behaviour can be traced back to that culprit. It’s also a good idea to install new apps one at a time and then looking for any performance hits on your system. If there is, try removing the offender and seeing if you get your speed back.
We’ve seen positive reports on a few different RAM Optimiser apps, with DU Speed Booster & Antivirus proving amazingly popular on the Google Play Store. The app currently has over ten million reviews, and proudly sits with an average score of four and half stars, which is frankly the best advertisement any company could ever ask for. Memory Booster can’t match the amount of reviews, but its smaller audience is again positive about the app’s ability, with the same being true of Memory Booster RAM Optimizer X, and Smart Booster.

So the bottom line is that these apps can make a difference. The best part is that most of the above are available for free, so you can try them for yourself and see whether your phone lasts a few more hours before the power cord beckons.
There are plenty of portable power banks available – see our round up of the best power banks – but with most of these you need to lug around not just the extra battery but a Lightning or (worse) MicroUSB cable too.
The best solution is a case that includes a built-in battery. Battery cases have a dual purpose: recharge a fading phone battery when you need it most; and protect your fragile smartphone from everyday knock, drops and scratches – and sometimes worse.
The iPhone 6 had a battery capacity of 1,810mAh, compared to the iPhone 7’s 1,960mAh. That’s a little better but not a lot. Crucially, it’s not enough for most users. Apple claims that the iPhone 7’s battery will give you a couple of extra hours battery life over the day. Read our iPhone 7 review.

The iPhone 7 was released in September 2016, and so far there are not many battery cases available for it. We will continue to update this round of the best iPhone 7 battery cases as more arrive.
The best iPhone 6/6s battery cases included the ThinCharge, Tylt Slider, iWalk Chameleon, plus the Juice Pack range from battery-case champs Mophie. None of those are yet available for the iPhone 7.
It is possible to fit the iPhone 7 into an older iPhone 6 battery case, but the likelihood is that the camera cutout won’t fit the iPhone 7’s new camera bump properly, leading to poor photos or no photos at all.

One of the iPhone 7 battery cases reviewed here claims to be compatible with the iPhones 6, 6s and 7, due to its larger rear camera cutout, but most 6/6s cases fail the camera cutout test.
Best iPhone 7 battery cases: Power
It’s not quite as simple as it sounds but look for a large battery capacity in the case. It needs to be at least 2,000mAh (milliamp hours) but that would just scrape a full recharge, and more likely give you just 80 percent more juice – enough but there’s better out there. See Phone battery charging tips and Tips to Boost iPhone Battery Life.

Best iPhone 7 battery cases: Protection
An equally important role of the battery case is to protect your phone from bangs, crashes, drops and bumps. We look at case robustness in all our tests. Also note that while the iPhone 7 is waterproof, most cases are not.
Best iPhone 7 cases: Design
Look for lightweight and slim battery cases if you value the iPhone’s naked statistics. You usually sacrifice some slimness for extra battery capacity. Try to choose a battery case that uses Apple’s Lightning charge and sync cable rather than MicroUSB as that avoids having to keep two different types of cable – one of which (MicroUSB0 is fiddly.

Out the same day as the iPhone 7 – well, Apple did have an obvious advantage in getting iPhone 7 accessories out – the Apple iPhone 7 Smart Battery Case is an update on its similar product for the iPhone 6 and 6s.
It features the same odd hump on its back, which hosts the extra battery. Many people were horrified and revulsed by the somewhat clunky design – especially as everything else Apple designs wins awards for subtlety. The Smart Battery Case will not. That said, the bump on the case’s back didn’t bother me at all.

It is, however, as a practical design, and the case feels both nice to hold and feels robust in its protective role. It has a soft-touch rubbery silicone exterior, and a soft microfiber lining that’s gentle to your scratch-prone iPhone (especially the Jet Black model). The case has a soft elastomer hinge that makes it super easy to slip the iPhone in and out of the convenient one-piece design. Many battery cases come in two parts, which can sometimes detach and get lost or snapped.
You can sync and charge the iPhone 7 and Battery Case at the same time when the phone’s in the case. This uses the same Lightning cable you get with the iPhone.
Unusually the iPhone 7 draws power first from this case, before using its own internal power. Most other battery cases let the phone drain its own battery first, and then use the extra case battery. The case ensures that the iPhone will have 100 percent charge, as long as it can.

There’s no LED battery life indicator on the exterior of the case, although curiously there is one on the interior. Instead battery status is displayed on the iPhone Lock screen and in the Notification Centre. At first this seemed odd, but you get used to it quickly, and is actually a neat idea.
The iPhone 7 Smart Battery Case has a 2,365mAh charge capacity, which is lower than most battery cases but enough for one full recharge, but no more until it gets charged again itself.
At £99/$99/€119 the Apple iPhone 7 Smart Battery Case is not cheap, but if it both protects your precious phone and gives you enough power for the day then it represents good value, and as it’s made by Apple you can be sure of its build quality and safety.

The PEMOTech Battery Case claims to be compatible with not just the iPhone 7 but the 6 and 6s as well. It can do so because the rear camera cutout is large enough for the cameras on each model.
This also means you get a headphone jack port, which of course is useless on an iPhone 7, which has no such port itself. Apart from aesthetically this doesn’t matter at all.
Hooray! It uses Apple’s Lightning cable to charge and sync, but the port on the case is to the right side (because of the redundant headphone port), and so you can’t use wired headphones while the iPhone is in the case – even with the Lightning adapter. If you want to use headphones while using the case they will need to be wireless. See our best Bluetooth headphones reviews.
With a large 3,200mAh battery capacity this case packs a decent power punch, more than the Apple iPhone 7 Smart Battery case. However, in testing we didn’t see a much greater boost than with the lower-capacity Apple case – sometimes only 90% of a full recharge.
