Types of Phone Battery Life

Today, there are two most commonly used smartphone batteries: Lithium Ion (li-ion) battery and Lithium Polymer (li-poly) battery. Each type has its own advantages and disadvantages. However, lithium polymer is being used more widely in the market.

1. Lithium polymer battery

Lithium Polymer batteries are the most advanced batteries available on the market and these are used by a number of vendors. They are made from plastic instead of metal, which makes them usable on any kind of smartphone. Having said that, they can be used in a smartphone with thicknesses from 5.2 mm to 10 mm. And, they're also the strongest, and of course, they explode if you don't craft them correctly. Lithium Polymer batteries have no memory impact and offer 40% longer battery life than the other batteries on this list.

Choose the Moto G Power and you'll discover a budget phone with a 5,000 mAh battery that will keep you going all day without charging. In our testing, this smartphone with the best battery life lasted over 16 hours, beating its predecessor by half an hour. Don't expect fast charging from this phone. After 30 minutes of low charge, the Moto G Power battery indicator shows only 21%. Then again, 5,000 mAh is a powerful power pack to fill up and you won't need to charge this phone as often.

The OnePlus Nord N100 has the same size battery as the Moto G Power. Furthermore, it has a lower resolution display of 720 x 1600, so it is likely to consume less power in the first place. This battery phone has a 6.52-inch display, a triple-lens camera with a 13MP primary sensor, a 2MP depth sensor and a 2MP macro sensor, an 8MP selfie camera, 18W charging, low-end Snapdragon 460 chip, 4GB RAM, and 64GB of storage. Unlike other recent OnePlus phones, OnePlus Nord N100 doesn't support 5G, but you still get a lot of your money.

The camera on ASUS ZenFone 6 grabbed all the attention - it revolved around letting the same lenses work as dual front and back cameras - but for us, this phone's durability is the real deal. ZenFone made it to our list of best phone battery life when it lasted more than 15 hours on our battery test - it's no surprise there is a powerful 5,000 mAh power supply inside ZenFone 6. Fast charging and efficient Snapdragon 855 processor, and that's a lot of power for a phone that starts at an affordable price.

The LG V60 ThinQ 5G continues LG's recent long-running series of phones, even as the handset boasts of power-hungry 5G compatibility. LG went big with the battery, putting a 5,000 mAh battery inside the V60. That lasted the phone for almost 13 hours on our battery test, making it the best android phone for battery life. Even then, 7 hours and 34 minutes of battery life when you power a pair of 6.8-inch monitors is quite an impressive feat.

The Samsung Galaxy S20 Ultra is the most premium flagship phone with best battery life, with no compromises and includes a whopping 5,000mAh battery. That gives this phone a lot of life, although the use of advanced features like 120Hz and 5G screens could alleviate this somewhat. Elsewhere, the Samsung Galaxy S20 Ultra has top-notch power, a four-lens camera led by a remarkable 108MP sensor, a large 6.9-inch 1440 x 3200 display, and almost everything else you may want sensible from a phone.

2. Lithium ion battery

The Lithium Ion battery is advanced and allows a high charge capacity based on the size and weight of the battery. However, these Lithium Ion batteries are a bit expensive and are not compatible with older smartphones. Having said that, these Lithium Ion batteries will not remember the charge cycle, and therefore, the capacity will not be reduced.

One of the most famous Lithium Ion phones that we cannot help but mention is the iPhone. However, the battery capacity of the iPhone has never been something to be proud of or competitive with other phones. But if you are a fan of Apple and are wondering what kind of iPhone has the best battery life, we recommend the iPhone 11 Pro Max.

Of all the iPhone versions we have reviewed and tested, the longest is the most premium handset of 2019, the iPhone 11 Pro Max, achieving a total of 20 hours and 7 minutes in our testing. That's a very good result and while it might just be our list of phones with overall top battery life, it's encouraging news for the future of the iPhone.


Buying guides best battery life phones

1. Compare capacities for just the same device

It's not as complicated as it sounds. First, just compare the batteries from Android phones with other Android phones. Comparing an iPhone's battery capacity to another Android phone wouldn't be very reliable. Second, compare the batteries between devices with similar screen sizes. So let's compare a 5 inch screen device with another 5 inch screen device (or in a 5 inch screen device in both directions). But be careful not to compare a 4-inch device with a 6-inch one. The larger the screen, the more power is required and the battery requirements are greater. Third, compare devices with similar processor speeds. In the Qualcomm processor family, smartphones using the Snapdragon ™ 8xx architecture require a larger battery than smartphones with the less capable Snapdragon ™ 4xx architecture. Similarly, a larger display requires a larger battery than a smaller one.

2. Understand your own usage

Some of us are casual users who use their mobile devices to occasionally use e-mail, texting and phone calls; others are business executives who travel constantly on their devices; Of course, the younger generation who can be glued to their favorite social networking app will have a different usage profile. If you are a casual user, you will most likely be satisfied with a battery capacity up to 5000 mAh. If your phone's capacity drops a little during the day, plug it in… you're probably close to an outlet most of the time. If you're an executive who needs a smartphone (and especially a display) constantly, use the greatest capacity you can find. Currently, 3,000 to 3,200 mAh is available on one type of Android smartphone. 

The  iPhone 11 Pro Max capacity is about 3969 mAh. Batteries at such capacity seem to be able to last at least a day of heavy usage. The Moto G Power  (5000 mAh) can keep comfortable throughout the day, from early morning till late at night. A teen who likes their social networking apps will also require a battery with the best capacity above 3000 mAh (or they'll have to charge more than once per day). Think of it this way, if you have a fast processor + your display is always on + you load / upload data continuously, then you most likely need the battery with the largest capacity possible.

3. Charging time requirements

Manufacturers tend to hesitate to disclose their charging times. If and when they do, the statements are a bit murky. That's because charging times are complicated: some manufacturers slow charging times to extend cycle life (i.e., battery life). Other manufacturers will turn on a green light (battery full) at 90% not 100%. The fastest current phone charges in the vicinity from 2 to 2.5 hours. Others can take up to 4 hours to charge (such as Moto G Power and OnePlus Nord N100)

4. Cycle life

Manufacturers will try to hide their life cycle performance. For some of them, there's nothing to write home about. If you are in the US and use the Verizon network, chances are your phone is designated for 800 cycles (or about 2 years if you charge it once a day) .... but it's difficult to verify. 

If you are using AT&T or other North American networks, your phone will most likely be assigned to only meet 500 cycles. A cycle life rating of less than 800 cycles means, especially for the proficient users of us, that in less than 6 months of use, you may notice a dramatic reduction in battery life. In other words, you'll likely wake up after a few months of use and realize that your smartphone isn't running for you all day. 

Worse still, if you find yourself charging more than once per day, even 800 cycles isn't enough - you'll lose serious capacity within a few months or less. Don't make mistakes and buy a phone you'll regret after a few months of use.


FAQs

1. What affects my phone's battery life?

First things first, battery size. If you want to choose the best battery life phone, consider the size. Not all smartphones have the same battery size or charging capacity. If you want phones with the longest battery life, look for the smartphone with the most mAh. The more mAh a mobile phone has, the longer it will use between charges.

2. What is mAh?

mAh stands for "milliampere hour" and it refers to the amount of charge that the cell phone battery can provide. Each of the phones in this phone's best battery life list is assigned a mAh value, which is calculated based on average usage - our best battery phones have the highest mAh (around 5000 mAh) including: Moto G Power, OnePlus Nord N100, ASUS ZenFone 6, LG V60 ThinQ 5G and Samsung Galaxy S20 Ultra). This can be used to estimate battery life hours (although in practice this will vary depending on how you use your phone).

3. How does your phone screen affect battery life?

As a general rule, smartphones with larger screens have more surface area, which in turn requires more power to illuminate the screen. Plus, higher resolution models have more pixels, which requires more processing power. The same goes for phones with higher refresh rates; having a 120Hz display means it refreshes twice as often as a standard 60Hz display. This action will require more power in addition, which means battery life.

4. How does the camera affect phone battery life?

Phone cameras take a lot of processing power as they are the extra piece of hardware your phone's battery needs to support. If you use your phone camera a lot, whether it's taking selfies or recording videos, that puts a huge demand on your phone's battery. This is especially true of smartphones with professional-grade camera capabilities, such as recording movies in 4K resolution, as they consume more battery power.

5. What are the tips for extending battery life?

If your phone has a low power mode, you might not need to go through these steps. This feature will automatically make some adjustments when the battery drops below a certain level.

  • Set the screen brightness to Automatic so that the device can adjust according to indoor and outdoor conditions.
  • Reduce baseline brightness. In most phones, you can do this using a slide switch in the Display menu.
  • Set the monitor to sleep after 15 or 30 seconds of inactivity.
  • Turn on airplane mode when you're in a location with no Wi-Fi or cellular data signal.
  • Reduce the frequency of updates for email, social feeds, and other apps to once per hour.
  • If you are streaming content over a Wi-Fi network to extend your data capacity (and perform other data-intensive tasks, such as playing Internet games), keep a set. source switch is available. Our tests have found that performing tasks over WiFi can drain the battery significantly faster than using a mobile data connection.
  • And if you need to quickly fully charge your battery before you leave, use a traditional charger instead of the wireless one. While wireless chargers have come a long way, you usually get plenty of juice faster just by plugging in your phone.
