A smartphone is only as good as its battery. After all, without any power, it’s just a good-looking brick. While most modern smartphones have decent battery life, here’s a list of the longest-lasting handsets today.
Naturally, you shouldn’t buy a phone purely for the battery life alone. So for this list, we’ve also taken into consideration the general performance of the device. And of course, you can always buy any of the top phones you like. The Samsung Galaxy S8 series, the LG G6, the OnePlus 5, and other flagship phones all have good battery life. In case you need more juice, you can also get one of the best power banks to extend the battery.
But sometimes, all you want it is a phone that won’t run out of battery at inopportune moments. If that’s the case, get one of these long-lasting babies.
1. Lenovo P2
Battery Capacity: 5100 mAh
Every battery test out there has crowned the Lenovo P2 as the champion. The gargantuan battery and Qualcomm’s power-efficient Snapdragon 625 processor form the perfect combo to last for a long time.
The P2 is generally a good phone, with good performance, 32 GB of internal memory, and 3 GB or 4 GB of RAM (depending on which model you choose). Even with the large 5.5-inch screen, the 5100 mAh battery will make sure you never run out of juice.
The Lenovo P2 also uses a proprietary quick charging technology, for which you need to use the Lenovo charger from the box. You won’t be able to use a standard QC-compliant quick charger.
Unfortunately, the phone isn’t available in the U.S., but you can get it in almost all other markets. U.S. residents will need to rely on international sites like AliExpress. If you are, remember our AliExpress purchasing tips. And make sure it works on your network. But for most American citizens, you are better off buying the Asus Zenfone 3 Zoom.
Battery Capacity: 5000 mAh
The Asus Zenfone 3 Zoom has been earning plaudits as the longest-lasting phone in the U.S. today. And why shouldn’t it? Like the Lenovo P2, this is a 5000 mAh battery coupled with a Snapdragon 625 processor.
But despite a battery that easily lasts a day, that isn’t this phone’s claim to fame. The Zoom is among the few smartphones to offer optical zoom (and not digital), with two lenses that focus at different ranges. And it can also shoot images in the RAW format if you want.
A few reviewers and users have noted that the Zenfone’s custom Android skin, Asus ZenUI 5.0, is a pain. It stutters and lags often, so you might want to replace it soon. Heck, you can get the stock Android experience without root too.
Battery Capacity: 5000 mAh
If you want great battery life and the assurance of the Samsung brand name, look no further than the Galaxy A9 Pro. It might be a year old, but it’s still the company’s longest-lasting battery.
The large battery is a necessity given the humongous 6-inch screen it sports. And there’s the fantastic Snapdragon 652 processor, which is great for gaming. You can enjoy playing on this phone’s large screen for many hours.
Most people aren’t fans of Samsung’s TouchWiz interface, and we even suggest that you replace Samsung apps with better alternatives. But in the case of the Galaxy A9 Pro, Samsung has done a good job of optimizing the software for best battery performance, so don’t mess with it too much.
Battery Capacity: 4900 mAh
As usual, the smart buy for Americans on a budget comes from Blu. The Blu Studio XL 2 ticks all the right boxes in offering a long-lasting battery and a decent overall phone experience.
It has a huge 6-inch screen, 16 GB of internal memory, 2 GB of RAM, 13 MP camera, and a quad-core MediaTek processor. There’s nothing to rave about or complain about.
But with those specifications, the large 4900 mAh battery will last you a long time — probably much more so than other phones with same sized batteries.
Unfortunately, there isn’t any quick charging tech available here, so filling up that large battery will take some time. You might want to check some tips to increase battery charging speeds.
Notable Upcoming Phones
The list here includes those phones that have plenty of real-world buyer reviews as well as tests by technology bloggers and journalists. A few phones haven’t got that treatment yet, but still seem like they might be worth keeping an eye out on when you make your decision.
The Motorola E4 Plus packs a mammoth 5000 mAh battery and an extremely power-efficient Snapdragon 427 processor. Add an HD screen and it promises to be an excellent budget buy.
Xiaomi’s first Mi Max bowled over everyone with its battery life. Mi Max 2 again has a 5300 mAh battery, and also a more power-efficient processor than its predecessor. The reviews have started rolling in, and it looks like this one is the longest-lasting phone from Xiaomi yet.
How Much Is Enough?
How many mAh do you look for in an Android smartphone’s battery life? Obviously, the bigger the better, but is there a minimum limit that you won’t go below?
