Battery Life and Charge Time

The Galaxy S 4 features a removable 9.88Wh battery with 3.8V chemistry. The battery design is par for the course for any high end smartphone, but the fact that it’s removable remains a staple of the Galaxy S design. Whether or not the bulk of consumers actually use the flexiblity offered by a removable battery is up for debate, but there’s no doubt about the fact that Samsung has a strong following of users who appreciate the feature.

Unfortunately, only having access to the Sprint version of the Galaxy S 4 to review, most of our battery life tests on the cellular network aren’t all that useful. The good news is that our WiFi tests should at least give you an idea of how well the SGS4 will compare to the HTC One when both are on the same network. We’re using the latest revision of our smartphone battery life test to compare performance of all the key players here. This is now our sixth revision of the battery life test, and we feel is the optimal balance between challenging workloads and idle time. The basic overview is the same as the previous test — we load webpages at a fixed interval until the handset dies, with display set at exactly 200 nits as always. Power saving features are disabled if they turn on automatically, and background account sync is disabled. The test is performed over both cellular data on all available air interfaces and over WiFi in an environment with good signal levels. The new test has decreased pause time between web page loads and added a number of JavaScript-heavy pages. I sat down with some UMTS RRC (Radio Resource Control) emulator tools and also made sure we had a good balance of all the RRC states (DCH, PCH if possible, FACH, IDLE) so we weren’t heavily biased towards one mode or the other.

As the most relevant comparison of platforms we have today, we’ll start with the WiFi version of our web browsing test:

On WiFi the Galaxy S 4 falls behind the HTC One by an appreciable amount, however there’s still an improvement in battery life compared to the Galaxy S 3. The Galaxy S 4’s battery life isn’t bad by any means, but do keep in mind that this is a large phone with a large display and a very powerful SoC. For much of the past year we’ve been talking about an increase in dynamic range in total platform power of high end smartphones and the Galaxy S 4 is no exception. Run it at full brightness or keep many cores running in their maximum performance states for a considerable period of time and you’ll be greeted by a phone that’s quickly in need of a power outlet.

As I mentioned earlier, we only have access to the Sprint version of the Galaxy S 4 at this point which unfortunately means that our 3G results aren’t all that comparable to other devices here.

Even on Sprint, the Galaxy S 4 does surprisingly well.

Talk time is excellent on the Galaxy S 4, with the phone delivering effectively the same battery life as the HTC One. Without having to power on that huge display, the Galaxy S 4 can last for a very long time on a single charge.

A combination of the Sprint network and the fact that the Galaxy S 4’s display remains off during our hotspot test resulted in great battery life here as well. Again, this data isn’t all that useful if you’re not on Sprint but Samsung tells us we should be able to get our hands on an AT&T SGS4 in the not too distant future.

Charge Time

Samsung appears to implement Qualcomm’s Quick Charge specification in the Galaxy S 4 and its bundled charger. I realize we haven’t done a deep dive into what Quick Charge is and how it works, but I’ll try to go through a quick explanation here. Most conventional chargers are linear, they take a fixed amount of input current (at 5V) and pass it along to the device being charged. The problem is that at deeply discharged states, the device’s battery might be at a substantially lower voltage. A traditional linear charger won’t change the current supplied based on the voltage of the battery being charged, and as a result can deliver sub-optimal charge times. When implemented, Qualcomm’s Quick Charge technology can vary output current based on the voltage of the battery being charged, which results in less power being dissipated as heat and more being delivered to charging the battery itself. The table below helps illustrate the savings:

Quick Charge, at least in its currently available 1. 0 specification, is still bound by the 5V limits of the USB BC 1.2 specification. The next revision of Quick Charge will enable higher voltage operation for even faster charge times.

Qualcomm Quick Charge 1.0, Theoretical Example
  Input Current @ Voltage Input Power Output Current @ Discharged Battery Voltage Output Power
USB BC 1.2 — Linear Charger 475mA @ 5V 2.375W 475mA @ 3V 1.425W
Qualcomm Quick Charge 1.0 475mA @ 5V 2. 375W 700mA @ 3V 2.100W

The non-linear nature of Quick Charge significantly shortens charge time, particularly in the very early stages of charging when the device’s battery is presumably fully discharged. As the device’s battery voltage increases, current delivery tapers off and the QC advantage is no longer as great as a standard USB BC 1.2 solution. The end result though is significantly improved charge times.

The graph below shows the benefits of using Samsung’s own charger vs. a standard charger that implements the USB BC 1.2 specification. When used with the bundled charger, the Galaxy S 4 recharges much faster than HTC’s One, despite using a larger battery. Obviously the Galaxy S 4 will charge with any USB charger, but the charge time will simply be longer. Samsung uses a voltage divider and signals the presence of their own charger by sending 1. 2-1.3 V across the D+ / D- pins, this is similar to what Apple does with 2.0 or 2.8 V across the pins for various USB chargers they’ve shipped over the years. This signaling is essentially Samsung’s proprietary tablet charging signaling which they’ve employed on the Galaxy Note 2 and now SGS4, in fact the two use the same exact charger, so it’s worth tossing out your old ones and getting the appropriate one to take advantage of the faster charging.

          How to Make Your Galaxy S4’s Battery Last Longer — Samsung Galaxy S4 User Guide — Tips, Tricks and Hacks

          Improve Your Phone’s Battery Life

          Admit it: You’re addicted to your Samsung Galaxy S4. Maybe it’s the big and beautiful 5-inch AMOLED screen. Or the nifty Eraser mode for the 13-megapixel camera. Or is it the gesture controls? With all of these features and more at your disposal, it’s all too easy to drain your Galaxy S4’s battery life. In our testing on multiple networks, the S4 lasted anywhere from 5 hours and 15 minutes (AT&T) to 6 hours and 45 minutes (T-Mobile). Given that the average smartphone lasts about 6 hours on a charge, that kind of endurance isn’t bad, but you can do better. Here are 10 tips to make your GS4 last longer. — Joe Osborne

          Use Samsung’s Power Saving Mode

          With the Galaxy S4, Samsung introduced a suite of power-saving features that users can toggle with a single tap. With Power Saving Mode activated, the phone limits the maximum performance of its CPU so as to draw less juice, uses a lower power setting for its screen and disables haptic feedback.

          What’s even better is that that you can toggle each of these features within the tool as you please. That way, when you activate Power Saving Mode, you’ll know exactly which limits you’re placing on your device. Tap Power Saving in the Quick Settings menu when you slide down from the top of the screen. And press and hold this button to tweak the power saving mode settings.

          Turn Off Unnecessary Connections

          From LTE to NFC, the GS4 comes with just about every connection imaginable. While each will come into play through the phone’s bevy of features, you’ll rarely need each type of connectivity raring to go at all times. So, we recommend disabling NFC, Bluetooth, location features, DLNA and even mobile data (i.e. LTE) when you’re not using them.

          You can shut off most of the above features in the Quick Settings menu by swiping down from the top of the screen and tapping a button. All of these options are also accessible through the Connections tab in the Settings menu.

          Optimize the Display

          We love the rich colors offered by the S4’s large 5-inch display, but it can be a power hog. Take control by going to the Display section under the My Device tab. We’d start with enabling automatic brightness, which makes your screen only as bright as it needs to by responding to ambient light. (You can also toggle Auto brightness by swiping down from the top of the screen.)

          Also, consider setting your screen mode to standard to keep your screen’s color, contrast and other levels the same at all times. Finally, you should find a darker wallpaper and lock screen image. Generally speaking, AMOLED displays use less power to brighten dark pixels than brightly-colored ones.

          Disable Motion and Gesture Controls

          You might have fun impressing your friends by answering your phone or switching music tracks with a wave of your hand. But your GS4 is wasting energy just waiting for you to pretend you’re a wizard. To turn off these features, tap on the Motions and Gestures menu under the My Device tab within Settings.

          If you want to turn off just Air Gestures, you can do that from within the Quick Settings menu by swiping down from the top of the screen and then tapping the Air Gesture icon.

          Close Idle Apps and Processes

          If you think you’ve closed an app by holding the Home button and swiping at it, think again. Many apps run separate processes that can zap your battery. To make sure that your GS4 is only running what is absolutely necessary, be sure to open the Task Manager by holding the Home button and then tapping the pie chart icon. From here, you can quickly and safely kill a number of applications with the “End all” button.

          If you want extra peace of mind, tap the Clear Memory button under the RAM tab to safely kill all processes that can be closed with a single tap. Not enough for you? Go to the Application Manager under the More tab within Settings. From here, you can individually close the processes that the above methods didn’t touch. But beware: Do not kill a process unless you know exactly what it does; otherwise, you could end up seriously impacting your device’s functionality.

          Disable Smart Screen Features

          To power features like Smart Stay (for keeping the screen on) and Smart Pause (for pausing videos when you’re not looking), the GS4 uses sensors to detect your eyes. Take the load off of your phone by disabling Smart Screen. Go to the Input and Control section within the My Device tab of the Settings menu. Then press Smart Screen. From there, you can individually turn each Smart Screen feature off to save some power.

          If you swipe down from the top of the screen and then press the grid icon in the top right corner, you can disable Smart stay and Smart scroll by tapping the respective icons.

          Disable Syncing and Automatic Updates

          When you’re running low on juice, you can squeeze more endurance out of your S4 by turning off automatic account syncing. Doing this will tell your phone not to update email, Facebook and other data in the background. Just swipe down from the top of the screen and tap the Sync button in the Quick Settings menu if it’s green.

          To disable automatic app updates, enter Google Play and press the Settings button. Then press the Auto-Update Apps button and choose the “Do not auto-update apps” option.

          Turn Off Haptic Feedback

          Haptic feedback, or the vibrations that occur whenever you touch the GS4 in certain situations (like typing), can draw precious power by activating a tiny motor inside your phone. You can disable this feature through one of two ways: through the Power Saving Mode tool, or through the Sound section underneath the My Device tab within the Settings app.

          Disable Air View Features

          Air View lets GS4 owners preview content just by hovering their finger above the screen. For example, you can see what photos are in a folder by expanding it or you can preview the contents of a message in the Email app. However, Air View can drain your battery because the phone needs to calculate whether you’re trying to touch the screen or hover, and even then the feature can be erratic.

          To disable Air View, swipe down from the top of the screen and tap the Air View button in the Quick Settings options that appear. Or you can head to the Input and Control section of the My Device tab within the Settings menu.

          Invest in an Extended Battery

          We’ve got you this far without asking you to spend a cent, but if these tips don’t grant you the endurance you seek, then perhaps it’s time to pony up. Thanks its removable back plate, the GS4 allows users to replace its 2,600 mAh battery.

          We highly recommend is the Mugen Power HLI-I9500XL. With its 5,500 mAh of capacity, this replacement battery more than doubles the lasting power of your GS4 without wrapping it up in an ugly case.
