If your phone runs out of battery much sooner than it should and you don't see anything unusual in your usual battery usage report, it's quite likely that there's something wrong. hidden apps draining energy in the backgroundIt's not always that the battery is old or damaged: often the problem lies in poorly optimized apps, neglected settings, and certain usage habits that leave it shivering by mid-afternoon.
The good news is that, although some apps may not appear to be obvious culprits at first glance, your smartphone offers Tools and clues to discover what's really going on with the batteryBy combining system settings, some signs of mobile behavior, and, if necessary, specialized apps, you can detect which applications consume battery even if they don't appear clearly in the typical list and stop them without going crazy.
Why do some apps drain your battery even when you don't seem to be using them?
Poor autonomy is usually caused by a mix of factors: Very bright screen, heat, always-on connections, and background processes that never stopMany applications (social networks, maps, weather apps, news, games, cloud backup services…) continue to function even if you don't open them, updating data, using GPS or keeping the connection to the server active.
This behavior causes some apps They may appear as "screen time" for only a few minutes, but accumulate many hours of background activity.In battery usage lists they may be camouflaged among other more visible ones, but if you pay attention to the details (backgrounds, data, temperature, storage…) you can catch them.
Furthermore, with each update, an app can change its behavior: new features, more aggressive advertising, or programming errors They can increase your battery consumption without you even realizing it. That's why, from one day to the next, your phone might go from lasting all day to giving up by mid-afternoon, even if you think you're using it the same as always.
Clear signs that an app is using more battery than it should
Before diving into menus and graphs, it's worth looking at the symptoms that reveal that Some app is behaving badly with the batteryAlthough that app doesn't appear as a major culprit on the standard list, your phone leaves some pretty obvious clues.
- Very rapid battery drain without a logical explanationIf you use your mobile phone as usual and see it drop from 100% to 60% in a short time without doing anything special, something is using a lot of resources.
- Device temperature increaseHeat is one of the best warning signs. If your phone gets hot in your pocket or when performing simple tasks (chats, light browsing), there are likely active processes running in the background.
- Frequent slowdowns, stalls, or jerksIf some apps freeze or the system responds slowly, there may be a process that is consuming CPU and battery power simultaneously.
- Continuous activity in the backgroundConstant notifications, active location icons without your request, and downloads or synchronizations that never stop are clues to an overly "nervous" app.
- Unusual spikes in data or storage usageIf an app you rarely use is consuming a lot of data or taking up gigabytes of cache, He's probably working much more than he should be.And that usually goes hand in hand with higher energy consumption.
How to use system settings to detect battery-draining apps
The first step is always configuring your phone. On both Android and iOS you have fairly detailed battery consumption reports which, when properly interpreted, allow the discovery of problematic applications even if they do not appear clearly in the usual top list.
Detect expensive apps on Android
On most Android phones, the path is very similar: Settings → BatteryDepending on the manufacturer, it may be called "Battery", "Performance", "Device Care" or similar, but there is always a section dedicated to energy.
Once inside, you'll normally see a download graph and a list of applications with their percentage of usageThe important thing here is not just the percentage, but also how and when they consumed it:
- Look for the section “Battery usage” or “Battery usage by application”On some models you'll see options like "Usage details" or "Show full device usage" to view all processes, not just the most obvious apps.
- Upon entering each app, check Screen time vs. background timeAn app that you barely use but that spends many hours in the background is a clear candidate for draining battery without appearing as a major culprit in visible usage.
- In interfaces like those of Samsung, Xiaomi, or similar devices, there are usually specific options such as “Background usage limits”, “Suspend” or “Put into deep sleep” to curb consumption.
On many Android devices, you'll also find notifications at the top of the battery section when an app It is consuming energy abnormally.If you see an alert like this, go in and check in detail which app it is, how long it has been active, and whether you really need it to behave this way.
How Android does it, according to the manufacturer
Each brand adds its own settings to refine this control and allow you cap the behavior of the most resource-intensive applications without having to uninstall them forcefully.
On Samsung Galaxy phones, the usual thing is:
- Walk into Settings and then in the section of Battery or Device Care.
- Review the list of apps sorted by usage and tap on the one you are interested in investigating.
- Activate options such as “Background usage limits”, “Suspend” or “Deep suspend”so that the app only uses resources when you open it or just enough to function.
On Xiaomi phones (and other brands with MIUI/HyperOS), the system also allows Cut off activity when you're not using the app:
- Ir a Settings → Battery and review the list of applications.
- Within each app, choose options such as “Close applications after 10 minutes of background activity” or “Restrict background apps”.
- If it's a dispensable app that's just annoying, the most practical thing to do is usually to uninstall it directly.
Detect expensive apps on iPhone (iOS)
On iPhone, the system also provides a lot of information for location purposes. apps that drain battery even when you're not viewing them in the foregroundThe route is very simple:
- Opens Settings → Battery.
- You'll see graphs of hourly and daily consumption, and below a list of apps with their usage percentage.
- Press on “Show activity” to see how long each app has been on screen and how long in the background.
The trick here is to look at the applications that You don't use it much, but it has many minutes (or hours) running in the background.And if these also coincide with times when the phone overheats or the battery drains rapidly, you know where to start cutting costs.
Apps that usually consume the most battery on all mobile phones
Beyond the specific listings on your device, there are two large groups of applications that almost always appear among the most expensive on any mobile phone, regardless of the brand or operating system.
1. Applications that use a lot of internet and GPS
These types of apps constantly use data, Wi-Fi, location services, and often the screen at full capacity. Some typical categories are:
- streaming apps: video and music platforms such as Netflix, YouTube, Spotify or Twitch They consume battery twice as much.Data or Wi-Fi + screen on for extended periods. If you use them a lot with high brightness and without Wi-Fi, the battery drains very quickly.
- Social networks and messagingInstagram, TikTok, Facebook, WhatsApp and company spend all day Syncing content, uploading videos, sending notifications, and updating the feedeven without you constantly opening the app.
- Web browsersChrome, Safari, Firefox, and others require a lot of CPU and data, especially if you open many tabs with heavy content (videos, ads, pages full of scripts).
- Maps and navigation appsGoogle Maps, Apple Maps, Waze, and similar apps are among the most They combine a screen on, constant GPS, and mobile data.Using the browser with high brightness for a while can drain the battery quickly.
- Demanding gamesPUBG, Fortnite, Call of Duty, and other graphically demanding titles require GPU, CPU, data, and often maximum sound. They are a real pile driver for batteryeven if you play for a relatively short time.
2. Applications with a lot of background activity
The second group consists of apps that, even if you're not looking at the screen, They continue to do things in the shadowsThey collect data, synchronize, monitor your activity, scan information…
- Fitness and health appsApps like Fitbit, Strava, Runkeeper and similar monitor steps, heart rate, GPS routes and sync data with the cloud, all while the phone is in your pocket.
- Banking and financial appsMany banking apps (BBVA, Santander, ING, etc.) perform periodic synchronizations, movement notifications, and security checks, which implies some background activity.
- Email appsGmail, Outlook, and other email clients run in the background checking for new messages, filtering spam, and synchronizing folders.
- Cloud storage appsGoogle Drive, Dropbox, OneDrive, and similar services drain battery Uploading backups, photos, videos, and documents without you having to do anything.
When the battery listing isn't enough: permissions, data, and storage
Sometimes, even after looking at the battery usage list, you still get the feeling that "something doesn't add up." In these cases, it's best to go a little further and review other parameters that reveal the actual behavior of the applications.
Review app permissions
On both Android and iOS, you can access the applications section within Settings and see what permissions each one hasLocation, microphone, camera, background activity, data access, automatic startup, etc.
If an app that shouldn't need it It has constant access to location, microphone, or background activity.It may not only be using more battery than necessary, but also compromising your privacy. Removing unnecessary permissions stops unnecessary processes and reduces power consumption.
Control data usage and storage
In the Storage and Mobile Data section of the system you will see how much space each app takes up and how much data it consumesIf you detect an application that:
- You use it little, but it appears occupying many gigabytes of cache.
- You barely open, but It consumes a lot of data in the background..
It is very likely that it has active synchronization processes, advertising or downloads that are not clearly reflected in the main battery list, but that do contribute to a constant drain.
Specialized apps to monitor battery status and consumption
In addition to the native tools, there are some very useful apps on Android for to monitor in detail what is happening with the battery and with each processThey are not essential, but they can help you fine-tune your sound.
AccuBattery
With this information you can see Which apps are driving up usage at different times of the day, how certain charging methods (fast, long, short) affect the battery and what habits you should change to avoid shortening its lifespan.
Greenify and other hibernation apps
Its main advantage is that It forces you to be aware of which apps you want active and which you don't.When looking at the list of applications you can hibernate, you often discover programs that you hardly use but that are still running in the background, draining your battery for no reason.
Antivirus and security tools
Some antivirus programs for Android include battery analysis modules that They detect suspicious processes, malicious applications, or configurations that trigger excessive consumption.They don't perform magic, but they can help you uncover disguised malware or apps that spy on your clipboard (flashlights, calculators, games of dubious origin…).
What to do when an app uses too much battery
Once you have identified the possible culprits, it's time to decide what to do with each app based on how important it is to youA social network that you check occasionally is not the same as WhatsApp or your banking app.
If the app is essential for you
In this case, uninstalling usually doesn't make sense, but you can reduce your power consumption without losing key features:
- Limit background activity: disable background updates or use system battery saving/optimization modes so the app works, but isn't running all the time.
- Reduce notifications and syncing: disable unnecessary notifications (likes, suggestions, promotions) and review the frequency of email updates, cloud backups, or news widgets.
- Check for and apply updatesSometimes a specific version of an app has a bug that causes a spike in data usage. Update to the latest version He can fix it and restore the battery to normal.
If the app isn't that important (or you suspect it isn't)
When it comes to games you hardly ever use, flashlight apps, obscure calculators, utilities you installed "just to try them out," or services that don't offer you much, the simplest solution is uninstall them and forget about themYou'll gain battery life, free up space, and, incidentally, reduce the overall system load.
In cases where you see a Excessive consumption of a little-known app, with unusual permissions, or from dubious sourcesIt could even be malware or poorly designed software. There's not much to think about: the safest thing for your phone and your privacy is to remove it as soon as possible.
Other key adjustments to make the battery last longer
In addition to hunting down and controlling apps, there are a number of settings and habits that They make a difference in autonomyeven if you don't touch anything else.
Screen brightness and animations
The screen is undoubtedly the biggest power drainer. Keeping it at maximum brightness all day is a surefire way to drain the battery. collapses much sooner than it shouldUse the automatic brightness setting properly or lower it manually whenever possible.
If the system allows it, you can also Reduce animations, transitions, and visual effectsNot only does it make the phone run a bit smoother on less powerful models, but it also slightly reduces the processor's workload and, consequently, its power consumption.
Connections: Wi-Fi, Bluetooth, NFC, GPS
Wireless connections are another ongoing source of expense when they remain active unnecessarily. If you're not going to use something, Turn it off without fear.:
- Turn off Wi-Fi and Bluetooth when you're out and about and don't need them.
- Turn off NFC if you don't pay with your mobile phone or use accessories that require it.
- Limit GPS usage to apps that truly require it and prevent them from having it "always" active.
It's not about spending all day turning icons on and off, but it is about Avoid having everything activated by default for no reason.In the long run, it makes a difference.
System updates and battery calibration
Keeping your system and apps up to date not only improves security; many updates include internal performance and consumption improvementsA more optimized system will always get more out of the same battery.
From time to time, especially if you notice that the battery percentage is behaving strangely, it can be a good idea to check it. Calibrate it following the manufacturer's recommendationsIt doesn't work miracles, but it helps the phone measure the actual level better and avoids giving you surprises.
Charging habits that take care of the battery in the long term
While they don't directly influence whether an app consumes more or less resources, your loading habits do determine it. How long will the battery remain in good condition?:
- Try charging your phone when it's around 20-30%.
- If possible, avoid leaving it plugged in for hours at 100%; many brands already include optimized load to control this automatically.
- Don't overuse your phone while it's charging if it gets too hot.
- Use original or certified chargers to avoid voltage and temperature problems.
By combining good load management with app control, it's much easier for your phone to make it through the day without complaining.
When the battery doesn't last as long as it should and no app seems particularly to blame, the problem is usually a combination of small factors: Apps running in the background without you noticing, incorrectly configured permissions, always-on connections, high brightness, and some bad charging habits.
Taking your time to review the Battery menus, checking background activity, adjusting permissions, taking advantage of each manufacturer's power-saving options, and, if necessary, using tools like AccuBattery or Greenify, allows you to discover those apps that consume battery even if they don't appear clearly on the list and recover several hours of battery life each day without having to change your phone.
