There are countless websites and countless people around the world reporting that the code “*#0228#” is used to calibrate the battery. While it is beneficial to all of us, the information received so far has not accurately confirmed whether the calibration process through the code is valid or not, and whether it is harmful or beneficial.

Anyway, I’m wondering what it does, the code in question and if it helps, harms or turns the smartphone into a brick.

Note:

1. If you enter the code “*#0228#” you will see the “Battery Status” screen and just below it “Quick Start”

2.Meu smartphone is a Galaxy Gran Prime Duos running Android 4.4.4 version.

The Samsung Galaxy S7 is the seventh addition to the Samsung Galaxy range, which serves as the flagship range each year. The Galaxy S7 introduced many improvements over its successor, the Galaxy S6, which was heavily criticized for its weaker battery and at times smaller screen. The Galaxy S7 offered a much better battery usage experience as the battery lasted a full day on one charge with normal usage. However, lately, many users have experienced that their phone is not lasting as long as it used to and draining the battery faster.

What causes the rapid battery drain on the Samsung Galaxy S7?

After receiving numerous reports about the issue, we decided to investigate the issue and based on our reports we have created a list of solutions that have solved the issue for most of our users and improved their battery draining experience. Also, we have compiled and listed the reasons for the occurrence of the problem.

Faulty application: It is possible that a certain application on the mobile phone is causing the battery drain by running in the background even using the data. Even if a particular application has stored a lot of cache on the device, it can drain the battery quickly.

It is possible that a certain application on the mobile phone is causing the battery drain by running in the background even using the data. Even if a particular application has stored a lot of cache on the device, it can drain the battery quickly. Outdated Software: If your device’s Android is not updated to the latest version, the phone may consume more battery as each application requires the latest version of Android for better compatibility and additional features. Therefore, older software can cause some applications to consume more battery thus causing the draining problem.

Therefore, older software can cause some applications to consume more battery thus causing the draining problem. Outdated Applications: If some applications are not updated to the latest version, they will end up using more power than necessary and cause battery drain. Therefore, all applications must be updated to the latest versions provided by their developers.

In addition, if some applications are not updated to the latest version, they will consume more power than necessary and cause battery drain. Therefore, all applications must be updated to the latest versions provided by their developers. Faulty Charging Methods: Using a charging cable or adapter that is not officially Samsung branded can also cause phone charging issues. The best way to charge the phone is to choose the phone charging accessory provided by the company.

Using a charging cable or adapter that is not officially Samsung branded can also cause phone charging issues. The best way to charge the phone is to choose the phone charging accessory provided by the company. Cache: Cache is stored by applications to reduce loading times and provide users with a smoother experience. However, if an application stores a lot of cache on the device, it can become sluggish and require more power to run, resulting in higher battery consumption than normal

Now that you have a basic understanding of the nature of the problem, let’s move on to the solutions. To avoid conflicts, make sure you implement these solutions in the order presented.

Solution 1: Identify the problem

In order to identify the application that consumes the most power from the mobile, we’re going to check the statistics, but first we have to make sure that the problem isn’t in the hardware. To do this, we will run the mobile in safe mode. For this:

Press the power button and select the “Power off” option. Once the device is completely off, turn it on by pressing and holding the power button for 2 seconds. When the Samsung animation logo appears, press and hold the Volume Down button.

The word “Safe Mode” should appear in the lower left corner of the screen if the process was successful. Now continue using the phone and see if the battery times change dramatically. If you only see a 20 or 30 minute improvement in battery life, there may be an issue with the phone’s battery health and the actual battery needs to be replaced. However, if the battery runtimes increase by more than 40 minutes, the battery has been drained quickly due to a software issue and you can continue with the guide below after booting from safe mode.

Solution 2: Delete bad applications

After determining that the problem is indeed in the software, let’s isolate the applications that are consuming a lot of battery and delete them. For this:

Pull down the notification bar and click the “Settings” button. From Settings, tap on the “Battery” option and then tap on the “Battery usage” button. In the battery usage details, identify an application that is consuming a lot of battery, taking into account the time you have spent using that application. Delete the application that is consuming the most battery and has not been used that much. Check if this fixes the battery drain b. If the issue is not resolved, try deleting other apps that are consuming a lot of battery. If the problem persists by deleting these applications, continue to the next step.

Solution 3: Check for application updates

If some applications are not updated to the latest version, they will end up consuming more power than necessary and cause battery drain. Therefore, in this step we will check for updates to all installed applications and apply them if available. For this:

Unlock the phone and open the Google Play Store application. Click the menu button in the top left corner and select the “My apps & games” option. Tap the Updates tab and select the Update icon. Click on the “Update All” option and wait for the applications to update and install. Check if the problem persists.

Solution 4: Check for software updates

If your device’s Android is not updated to the latest version, the phone may consume more battery as each application requires the latest version of Android for better compatibility. Therefore, in this step we will check if there are any software updates available for the application. For this:

Unlock the phone and open Settings. Scroll down and click on the “About device” option. Click on “Software Update” and select the option “Check for updates”. If a new software update is available, click the “Download updates manually” option that appears after the scan is complete. After the phone finishes downloading the update, you will be prompted to confirm the update installation. Select “Yes” and the phone will now restart. The update will be installed and the phone will restart in normal mode. Check if the problem persists.

Solution 5: Wipe Cache Partition

If an application stores a lot of cache on the device, it can become sluggish and require more power to run, resulting in higher-than-average battery drain. So in this step we will clear the cache. For this:

Press and hold the power button and select “Power off”. Press and hold the “Home” button and the “VolumeUP” button at the same time, and then press and hold the “Power” button as well. When the Samsung logo screen appears, release only the Power button. When the Android logo screen says to release all keys, the screen may say “Installing system update” for a few minutes before showing the Android recovery options. Press the Volume Down button until Wipe Cache Partition is highlighted.

Press the “Power” button and wait for the device to wipe the cache partition. When the process is complete, navigate the list using the Volume Down button until Reboot System Now is highlighted. Press the “Power” button to select the option and restart the device. After restarting the device, check if the problem persists.

Note: You need to be very careful during this process as even a small mistake while doing it can brick the phone software permanently.

Phone health: 5 signs it’s time to replace the battery

They say nothing lasts forever. This is definitely the case with smartphone batteries. We haven’t tapped into an infinite source of energy yet, so we’ll have to tolerate their finite lifespan for now. Most batteries typically begin to lose capacity somewhere between 300 and 600 cycles. After that, it can get pretty irritating. Not sure if your battery is bad or dying? Here are a few surefire signs that it’s time to replace the battery.

1) It won’t turn on

This is definitely the most obvious and easiest way to tell if your battery just has enough. Like anything without power, your phone just won’t turn on. However, if you’re still hearing notifications from your phone or seeing signs of power but the display is completely black, we most likely have a problem with the display and not the battery. There’s also a chance it’s your charger, so try a different charger to confirm it’s the battery.

2) Only shows life signs when connected to a charger

When your phone is completely dead and we have ruled out all possibilities of screen damage, let’s move on to the next step. Plug your charger into your device and watch for a few minutes. If your phone turns on and starts working, that’s great. Now disconnect the charger. If it turns off as soon as the charger is removed, your battery is definitely dead. This can be seen from the fact that the phone will only work when powered by the charger.

3) Dying quickly even after fully charged

On average, a modern smartphone (2015 or later) should be able to last between 5 and 8 hours from fully charged to fully discharged. Of course, this can vary drastically from user to user depending on a number of different factors. If you use your phone frequently, use apps that drain the battery, or forget to close apps when you’re done, this can put you in the 3 to 4 hour range. However, if you charge your phone until it’s fully charged, but the battery life drops extremely quickly (2 hours or less) or if it randomly dies completely, that’s another sign that your battery is dead. That’s life.

4) overheating

You probably loved playing the children’s game “Hot Potato” when you were a kid, right? That’s probably not the best game to play on your expensive smartphone now that you’re an adult. The average healthy temperature range for a smartphone battery is between 68 and 86 degrees Fahrenheit. Your battery can operate above this level, but this will have a negative impact on the overall battery life and performance. If your phone is hot to the touch, it’s not only dangerous, it’s another sign that your battery may be dead.

5) Battery bulges

If your phone’s screen is detaching from the frame of the device, this is most likely due to a bloated battery pushing the screen up. Battery bulging is caused by overcharging the battery cells. Like overheating, this is also a hazard. At this point, you have no choice but to replace the battery, especially before it cracks the screen!

Wondering how to calibrate your Android smartphone battery? Are you looking for answers as to why a battery calibration is necessary at all? Well, these are some of the questions we aim to answer with the help of this article.

What is battery calibration?

The Android operating system needs to keep track of your battery and charge level so it can tell you when it’s full or empty. The problem is that it sometimes gets corrupted and displays data that isn’t real, causing the phone to turn off before it reaches 0 percent, for example. This data discrepancy can also be age-related.

All batteries deteriorate over time, and an older battery may not be able to hold as much charge as when it was new. However, the software running on your phone usually does not take this degradation into account when displaying the battery status on the screen.

Calibrating your Android battery simply means that you get the Android operating system to correct this information so that it reflects your actual battery level again. It’s important to understand that this process doesn’t actually calibrate (or improve) the battery itself. Battery calibration also doesn’t improve your phone’s battery life. It only helps the phone to accurately display battery stats.

When should I calibrate the battery?

Wondering if your smartphone battery needs calibration?/ © NextPit

Calibrating your battery is not something you would do on a regular basis. As mentioned, battery calibration serves one purpose only: to ensure that the battery stats displayed by the phone reflect the actual state of the battery. Unless you’re having an issue with your phone showing you erroneous battery stats, you probably don’t need to calibrate your battery. Below are the circumstances when it might be a good idea to calibrate your battery.

Your smartphone turns off suddenly, even after indicating that there is enough charge left. If your loading percentage is stuck at a single point for a long time. Your smartphone is really old and you suspect that the battery statistics displayed are inaccurate.

Before you calibrate your smartphone battery

Sometimes replacing your smartphone’s battery is just easier (and better) than whipping up an old horse and trying to calibrate it. This was easier on older smartphones with removable batteries. With such devices, checking the battery for damage/issues was easy as turning off the device, removing the cover and checking the battery.

If you have a phone like this lying around, you’ll need to check for any bulges or leaks. In the image below you can see what a regular battery looks like next to a swollen one.

A swollen battery is easy to spot / © NextPit

With most modern smartphones, it is not possible to remove the back cover and there is no way to look at the physical condition of the battery. However, one method to identify a damaged battery in smartphones with a built-in battery is to check if it is no longer lying flat on the table – a situation that can often occur due to a swollen battery.

Additionally, calibrating the battery is not an all-weather solution to battery-related issues.

This is because there are many other things that can cause a battery to malfunction. If your phone is not charging, there may be a problem with the port. So check out our guide on what to do when a phone won’t charge.

If you recently updated your phone to a new software and the battery-related issues started appearing right after, it is probably caused by the new firmware and not the battery itself. In such a scenario, it is better to just wait for the brand to issue a fix.

The process mentioned below applies to all Android smartphones. If you have a Samsung device, click here.

Discharge your phone completely until it turns itself off.

Turn it back on and let it turn itself off.

Plug your phone into a charger and let it charge without turning it on until the screen or LED indicator shows 100 percent.

Disconnect your charger.

Turn on your phone. It’s likely that the battery gauge isn’t showing 100 percent, so reconnect the charger (leave your phone on) and continue charging until the screen shows 100 percent as well.

Disconnect and restart your phone. If it doesn’t show 100 percent, reconnect the charger until the screen shows 100 percent.

Repeat this cycle until it shows 100 percent (or as close as you think it will come) when you start it without it plugged in.

Now let your battery drain down to 0 percent and let your phone turn off again.

Fully charge the battery again without stopping and you should have reset the Android system battery percentage.

How to calibrate the battery on Samsung smartphones?

Samsung smartphones come with an option called “Quick Reset,” which technicians typically access to calibrate phones that are reporting inaccurate battery stats. Here is how you can use this option to calibrate the battery on Samsung devices.

Use the smartphone until it reaches 5% and make sure your phone is not connected to the charger.

Open the phone dialer app and enter the following code: *#0228#.

A pop-up menu will appear with the option “Quick Start”.

Press Quick Start and then OK.

Wait for the display to turn back on and check if the battery percentage has gone down.

Charge the phone to 100% again.

Turn the phone off and on again, then disconnect the charger.

Repeat these steps 2, 3 times

Reconnect the charger and charge the battery to 100%, turn the phone back on, open the dialer and enter: *#9900#.

Scroll down to “batterystats.bin reset” and tap on it.

Exit the menu and restart the phone.

Keep in mind that it is not recommended to do this process regularly. Even if your battery is so drained that your phone won’t even turn on, your battery will still have enough reserve charge to prevent system damage. But you don’t want to poke the tiger with a stick. Do this process at most every three months. If it is needed more often, you have bigger problems.

Put simply, completely draining a battery is bad for it. Attempting to overcharge a battery is also bad for them. The good news is that battery charging automatically shuts off when it reaches its safe limit, and there’s always some reserve even if your phone won’t start. Again, only do this if absolutely necessary, as it will negatively impact battery life.

How to Fix Galaxy S7 Battery Life Problems

The eternal quest for longer battery life in smartphones continues as increasingly efficient chips and larger batteries battle it out with new software, apps, features and large screens. You want your phone to be able to do everything, but also for a very long time – and those things are at odds, especially if you don’t want to be chasing an outlet everywhere.

The Galaxy S7’s 3000mAh battery is bigger than the Galaxy S6 and offers really solid battery life. But if you find that your GS7 always falls short at the end of the day – especially as it ages – we have a handful of tips for you to get the most out of your battery.

Be on the lookout for battery-hungry apps

As much as we wish every app out there was written to be a great phone burgher and to be careful with your phone’s limited resources, unfortunately it isn’t. If you’ve installed a bunch of apps and are finding that your phone’s battery is draining faster than you’d like, you can take a look into the phone’s settings to try and diagnose what’s going on.

Go into the phone’s settings, tap on battery and then tap on battery usage. This isn’t a definitive list of apps that are using your battery, and if you actually use an app a lot it will of course show up, but the battery usage screen can indicate if something is chewing your battery without your knowledge. If you find an app that keeps misbehaving, you should uninstall it.

Look at the settings for “App power saving”.

Even if you identify and remove power-hungry apps from your phone, there are many other apps you want to keep that are still running unnecessarily in the background. The best way to handle this is in the Galaxy S7’s “App Power Saving” settings, located in the battery section of your phone’s settings.

When app sleep mode is turned on, your phone limits apps’ ability to run in the background if you haven’t used them for more than five days. For example, if you haven’t opened the Foursquare app for five days, it can’t be running in the background because you’ve expressed that you’re not interested in keeping it running all the time. The app still works when you open it and that resets the counter so it can be optimized again.

In Settings, you can customize app by app what you want the settings to look like — by default, the app saves power after five days of inactivity, but you can also set it to always save power or never save power. For example, you might want a travel utility like the American Airlines app to always be able to run flight updates, even though you might not open it every five days.

Uninstall or disable unused bloatware

If you bought your Galaxy S7 from a carrier, chances are it’s loaded with a large number of apps – call them “bloatware” if you like – that you don’t want. These apps can run and drain your battery, and even if you don’t have a egregious culprit, a handful of bad actors could add up to a significant impact on battery life.

Instead of just ignoring those pre-installed apps or hiding them in your launcher, go through and uninstall what you can and disable the rest. Go to your phone’s Settings, find Applications, then tap Application Manager to turn it on get a list of apps. To find everything, tap More, then tap Show system apps.

Turn off unused radio devices like Wi-Fi and Bluetooth

This is true no matter what phone you have – if you plan on not using Wi-Fi or Bluetooth for a long time, just turn them off. With the Galaxy S7’s quick toggles in the notification bar, you can just tap and turn them off, and quickly turn them back on when needed. Now, of course, there’s no reason to bother turning off those two radios if you’re going to turn them on repeatedly throughout the day – convenience is important – but if you can go a long time without either one, take the two seconds to turn them off.

If you want to keep Wi-Fi on, you can at least turn off some advanced features that use a little more juice. From your Wi-Fi settings, tap More, then Advanced, and turn off network notification and any other auto-join hotspot settings your carrier may have added.

Use the low-power and ultra-power-saving modes

Samsung has fantastic built-in power saving modes on all of their newer phones that work really well. The one that most people will find useful is the default “Low Power Mode,” while “Ultra Low Power Mode” remains as the absolute last toggle.

When you turn on battery saver mode, your phone will do a handful of things to squeeze out a handful of extra percentage points when your battery reserves are low. The Galaxy S7 limits its performance, turns off vibration feedback, and limits location services to offer battery savings with minimal impact on your phone usage. If you want to go one step further, tap the settings switch to restrict all background data, which blocks apps from using data while it’s not open and in use. You can set the power saving mode to turn on automatically at 50, 20, 15, or 5% battery level, or you can just turn it on manually when needed.

Ultra power saving mode goes a few steps further and switches your phone to the bare minimum of performance and features to maximize limited battery resources. Your phone’s display will go into a grayscale mode, app usage will be restricted, cellular data will turn off with the screen, and extra radios will turn off. This is really for a last resort and really should only be used when keeping your phone alive is much more important than actually using your phone.

Make some changes to your display settings

The Galaxy S7 has an industry-leading display, and while it’s actually very efficient, it’ll still consume a large chunk of your battery throughout the day. If you dive into your phone’s display settings, you’ll find a few different tweaks you can make that won’t change the way you experience your phone while saving a few percentage points on your battery.

Screen brightness: Consider turning the screen brightness down a bit. You can still leave auto-brightness on for proper visibility in a variety of conditions, but moving the slider down a bit will lower the brightness in many situations.

Screen Timeout: The lower the better. Your screen doesn’t consume power when it’s off!

Always On Display: Depending on which AOD mode you’re using, it’ll drain too much battery, but if you can handle not having information on your otherwise “off” display, you can save a few percentage points by turning AOD entirely switch off.

It might seem obvious, but if you haven’t taken the time to update your Galaxy S7 to the latest version of software released by your carrier, you could be missing out on important battery life improvements.

To check if your phone has an update, go to Settings and About device and tap Download updates manually to check. When an update is available, it usually means that Samsung has fixed an important bug or added a feature that could have a positive impact on battery life, at least most of the time.

If there’s one thing we’ve found at this point, it’s that apps running when you’re not expecting it can be annoying. This also applies to the app stores that download and manage these apps, in this case Google Play and Galaxy Apps.

When it comes to Google Play, go into the app’s settings, tap Auto-update apps and set Don’t auto-update apps to save battery the most. If you’d rather get these updates automatically, but want to find a healthy middle ground, select Auto-update apps only over Wi-Fi, which also saves on mobile data costs.

In Galaxy Apps, tap the More button and then tap Settings to view the auto-update settings. Here Samsung distinguishes between automatically updating its own apps and automatically updating other apps that you have installed via the store. When it comes to Samsung’s own apps, the best option is the Wi-Fi Only setting. Other apps give you the option to select Disable.

Factory settings reset

If you’ve been using your Galaxy S7 for almost two years and are having issues, it might be time to start over with a factory reset. These modern phones have all sorts of schemes to try and keep their software running smoothly over time, but it’s an unfortunate reality that old software tends to slow down with prolonged use. As you add and remove data, swap out apps, and use your phone every day, it becomes increasingly difficult for the software to manage it — and so a factory reset can be a great way to fix all that leftover stuff.

Back up your important data—Samsung even offers a built-in backup service—then follow these factory reset steps:

Go to your phone’s Settings and scroll down to General Management. At the bottom, tap Reset. The other two options only perform slight resets on specific settings – a useful troubleshooting step, but not what we want here. Read the confirmation of everything that’s being reset and tap Reset device – you’ll be prompted to confirm your lock screen if you have one.

The phone will reboot and take a few minutes, and you end up with a new phone with nothing but the default software on it. Set up your phone again and you should see improved performance and battery life. Be careful what software and apps you install and you’ll do even better.

Use Fast Charge when you need to switch on

No matter what you do to extend the battery life of your Galaxy S7, the sad truth is that at some point you will actually need to charge it. When you finally charge your GS7, you should use the power adapter and cable that came with the phone. This charger will charge your Galaxy S7 at the fastest possible speed, which means you’ll be able to get the phone off the charger again in less time – just 30 minutes on the charger will add a significant amount to your battery.

If you want a second charger, look for chargers that are Qualcomm Quick Charge 2.0 certified for a similar experience if you don’t have the included charger available.

Last resort: consider a battery case

While all of the above tips can lead to a pretty significant increase in battery life, some people just can’t do what they need on their phones and keep the battery going all day. If push comes to shove, we recommend (reluctantly) that you look at a battery case for your phone. Our top choices come from Samsung itself and well-known case maker Mophie, both of which offer really solid options for the Galaxy S7.

Samsung’s Wireless Charging Battery Pack is sleek (by battery case standards), simple, and adds 50% to your Galaxy S7’s battery life by charging wirelessly, leaving your ports uncovered.

Mophie’s Juice Pack is slightly larger and adds 60% battery to your phone in about half the time of Samsung’s own case – and while it charges the phone via micro-USB, the case itself can be charged wirelessly.

Both will add significant bulk to your phone, but if you just can’t get through the day any other way, check out these.
