Android smartphones with the best battery life

Authored by: Scott Adam Gordon — 5 months ago

By what criteria do you judge a smartphone? Camera specs? Processing power? Water resistance, perhaps? For many people, the battery life is the single most important consideration. Even in 2015, if a device lasts more than a day before running out of juice, it is doing well. All the devices in this list pass that test with flying colors, so scroll on down to see our picks for the Android smartphones with the best battery life.

Which smartphone has the best battery? / © ANDROIDPIT

HTC One M9

At 2840mAh, the HTC One M9 battery is only marginally bigger than that in the HTC One M8. You'd think this would be a problem considering the One M9 is running a powerful Snapdragon 810 octa-core chipset. However, the big.LITTLE technology in the processor has paid off, as the One M9 battery manages to just outperform that of its predecessor.

Under extreme duress, like constant video-watching, the One M9 battery lasts around 13 hours, which is a decent run. However, no one in their right mind would watch a video for 13 hours straight (if you do, remember to take regular breaks), and ordinary users can expect well over a day's use out of it before needing to recharge. Another big plus with the One M9 battery is the quick-charging feature, which charges your battery around 40 percent in just half an hour (annoyingly, the fast-charging cable is not included in the box).

OnePlus One

There are plenty of things to like about the OnePlus One - its rebellious Cyanogen OS (and now also OxygenOS), its big screen, low asking price, and of course its powerful 3100mAh battery. With its Snapdragon 801 quad-core chipset, big display and 3GB RAM, there's a fair old bit to keep powered in the OnePlus One too.

The OnePlus One battery handles over 13 hours of heavy usage, including constantly-on internet, regular phone calls and some video-viewing. For a moderate user, this converts to about one and a half day's use.

Samsung Galaxy Note 4

The Galaxy Note 4 remains one of the best phones money can buy, largely thanks to its fantastic camera, big and bright 5.7-inch QHD screen, and S-Pen stylus features that make it truly unique among phones and phablets.

All these impressive features run smoothly thanks to the Note 4's Exynos 5433octa-core chipset, which is in turn kept alive by a 3220mAh battery. If you're a moderate to heavy smartphone user, then you should have around 30 percent battery remaining by the end of the day, and it should see you several hours into the next day as well. The Note 4 also comes with a fast-charging feature, which can charge up to half your battery within about 30 minutes.

We're just disappointed that Samsung failed to follow the Note 4's great battery performance through to the otherwise brilliant Galaxy S6.

The LG G3 is one of the best smartphones for battery performance when considering specs. The battery has a 3,000 mAh capacity, powering a 5.5-inch QHD LCD screen, a Snapdragon 801 processor and 3GB of RAM. With these innards, the LG G3 is considered a high performing device, but thankfully LG has done a great job optimizing its hardware to ensure the battery lasts. 

The device is able to last around 2 working days if you aren't running any particularly demanding apps, or playing games, a figure which is difficult to reach on devices with even lower specs. Of course, given the large display, it’s likely you will want to watch movies and play games in HD, and this will reduce the battery life to less than a day. Compared to the competition, however, the LG G3 is fantastic.

HTC One (M8)

There are a number of supporters in the Android universe of the HTC One M8, and for many this is due to its laudable battery life. While it doesn't reach the level of the LG G3, and has lower specs, overall the HTC One (M8) is still one of the better devices on Android for battery performance.

The 2,600 mAh battery powers a 5-inch Full-HD display and Snapdragon 801 processor. This Snapdragon processor has received a small, but significant, improvement over the previous version in terms of power consumption, and this is one of the keys to improving battery life. During normal use, you will easily find the HTC One (M8) lasting more than a day.

Samsung Galaxy S5

The Samsung Galaxy S5 is strong performer in a number of areas, not least in the battery department. For a start, the Galaxy S5 battery is removable, unlike some of the others on our list, meaning you can carry around a spare and swap them if necessary.

Another interesting aspect of the Galaxy S5's 5.1-inch Super AMOLED display, which has the advantage of consuming less battery than competing displays. Finally, the Galaxy S5 comes with a number of unique to Samsung power saving modes like Ultra Power Saving which can help add precious hours, or even days, to the Galaxy S5 battery. Samsung even pulled a publicity stunt with a week-long, cross country road trip on a single charge.

Sony Xperia Z3

The Sony Xperia Z3 has a battery capacity of 3,000 mAh, curiously lower than that of the older Xperia Z2. The key, however, is in how Sony has optimized the Xperia Z3's hardware. The Xperia Z3 is another smartphone in the 2-day battery life camp, often capable of hitting this benchmark with juice left in the tank. Unfortunately, Sony's omnibalance design means that, although the Xperia Z3 is water resistant, its battery is not removable. We also can't comment on how the Xperia Z3 battery will perform with the PS4 Remote Play feature. Nonetheless, it's still one of the best performing batteries for specs it houses, with 3 GB of RAM, Snapdragon 801 processor, and 5.2-inch full-HD screen.

Huawei Ascend Mate 7

The Huawei Ascend Mate 7 has one of the largest batteries on the market at a huge 4,100 mAh! The giant battery is necessary, though, to power this Chinese phablet's mammoth 6-inch Full-HD screen and octa-core Hisilicon Kirin 925 processor. Despite the big specs, the device will last for about two days with normal use if it is helped along by its power-saving modes (Smart or Ultra). Of course, we have yet to test the 6-inch Nexus 6 to see how that compares yet, but as it stands the Ascend Mate 7 is one of best devices for battery efficiency on Android.

  • Royal V5 by iDROID USA has a long lasting battery life. The battery runs for a day and a half and the interface of the phone is simple yet innovative.

  • My Sony Xperia Z3 Compact battery lasts almost 3 full days with business use.

  • Wtf is this? I'm coming here because of my crappy LG G3 and I see it among the "best" phones for battery life?

  • Elephone P5000 has a 5350 mAh battery. By far the largest I've ever seen.

  • None of this phone have a battery like THL5000. I have one 10 months ago and works like a charm. It really have 5000 MaH of battery and no loose of capacity in all this time.
    With Wifi and 2G reaches 5 days. With 3G I use it about 3-4 days. I don't use it too much but a person who uses it all day can have battery for 2 complete days for sure.
    I know SnapDragon is lower consummer thank mediatek but I won't change my THL5000 for any listed here...
    The only "but" in this device is GPS that works very well but it uses a lot of battery. Maybe using it continuos with Google maps the battery in 4 hours drops to 60%. But I use it in car and always connect it ;)

  • Which mobile (android or windows) has highest battery life ? Please suggest....

  • Lol 4800 on my phone

  • Hah! Lg G3 battery life is terrible. Using Google maps will drain it from 100 to dead in 4 hours even after a factory reset. I woke up one hour ago, unplugged my fully charged phone, got in the car, checked my email, looked at maybe 10 Webb pages, and it's at 90%. Need a new phone!

  • I just came from an LG G3 and "downgraded" to a xiaomi redmi note 4G and I have to say, even when new, the LG didn't hold a candle to this thing in battery life

  • zte zmax 3400mAh battery

  • mangesh 5 months ago Link to comment

    another article in android pit which clearly underestimated Motorola ....moto turbo has a whooping 3900mAH battery but people here are biased and don't play fair ...it doesn't matter coz moto will keep rocking your brains out

  • The HTC M9 has been slammed in several reviews for it's Shoddy battery life as well as the LG3 below is a quote from one review From Forbes the best & worst of the HTC M9

    "The M9’s battery life is poor. It has regressed from the M8, despite being larger. The M9’s 2840mAh battery is notably bigger than the M8’s 2600mAh power pack, yet there seems to be something rapidly draining power from the M9.

    As I said in my review:

    In one hour of constant use (browsing the web) – on low-brightness – I saw a drop in battery life from 44% to 27%. With medium use, the battery fared slightly better but drained faster than expected, particularly when 4G came into the mix. The best comparison I could make is that it lasts about as long as the LG G3, which had a power-sucking quad-HD display.”

  • The Note2 deserves this

    Where is Sony Xperia Z3 Compact? very misleading article.

  • My OnePlus One. 3.5 days battery life. WiFi/Bluetooth/GPS on 100% of the time. Sony SmartWatch 3 connected 24/7. 2-3 hours Bluetooth audio every day. Screen on around 4 hours during this time. Connected to WiFi around 60% of the time.

      my g3 actually gets good battery life. with the pre-installed battery saver feature does o.k. but I installed a different one that so far while using my phone has added 4-5 hours to my battery life... My g3 is the "Stock" 32GB G3. only reason I have to charge again during the day is because I am Constantly in dev or code site playing around with different source codes.. if I was to put it down and leave it alone I have no doubts I have a 3 maybe 4 day battery life.. I've noticed that the screen brightness EATS UP BATTERY

  • Loony 10 months ago Link to comment

    Wheres the G2? It has a much more powerful battery than the G3.
    Or the OnePlus One

    • perhaps their selection of phones in this article is based on a cutoff release date, lol.
