Causes of battery deterioration and malfunction on Android: What you need to know
Modern smartphone batteries, mostly from the latest technology, lithium-ion (Li-Ion), consist of a cathode (a mixture of lithium and other metals), an anode (graphite), and a special electrolyte. Each complete charge and discharge cycle wears down the battery and reduces its capacity. Over time, a build-up of lithium oxide layer on the anode thickens the internal resistance, making the battery last less.
Among the main factors that accelerate battery degradation are:
- High temperaturesHeat is the main enemy. Charging or using your phone while it's hot accelerates wear and tear.
- Full downloads: Letting the battery frequently reach 0% can damage internal cells.
- Overloads: Keeping the charger connected after reaching 100% causes additional microcharges.
- Fast charging and unofficial sources: If your device does not support fast charging, using high-power adapters may damage it.
- Intensive use while charging: Browsing or playing games with your phone plugged in increases its temperature and accelerates wear.
How to know if your Android's battery is in bad condition
Many manufacturers don't provide explicit battery health data for their systems, except for specific models or recent Android versions. However, you can identify signs of deterioration if:
- You have unexpected blackouts even when the battery percentage indicates high values.
- The charge is depleted much faster than normal.
- Notes a excessive rise in temperature during use or charging.
- The phone turns off by itself when power is required (games, camera, etc.).
- You experience sudden and irregular changes in the displayed battery percentage.
- The app you use (such as AccuBattery, Ampere, GSAM, or Electron) indicates an actual capacity that is much lower than the nominal capacity.
On Samsung models, you can access the 'Device Care' feature in Settings and view the battery status under 'Diagnostics'. On other devices, you can enter *#*#4636#*#* in the phone app to access test information (although it doesn't always show the battery health). The apps mentioned above are usually the best all-around solution.
Essential tips to preserve and improve battery life
Analyzing all the recommendations validated by experts and manufacturers, these are the most useful and current habits To prolong the health of a battery and improve its real autonomy:
- Avoid discharging the battery completelyWhenever possible, keep the charge between 15% and 80% to reduce cycle stress.
- Do not keep your phone plugged in when it reaches 100%.. Unplug it to minimize additional microloads.
- Use the original charger and cable or certified by the manufacturer.
- Avoid extreme temperatures both during charging and intensive use.
- Do not use your phone while it is charging. to avoid overheating.
- Activate energy saving mode integrated into Android when needed.
- Close or limit high-power background appsThe apps we've seen (Greenify, Battery Guru, etc.) can help you hibernate them automatically.
- Reduce brightness to the minimum necessary and use dark modes or black backgrounds on AMOLED displays to save battery.
- Uninstall unnecessary apps and remove widgets or services you don't use.
- Disable wireless connections (WiFi, Bluetooth, GPS, mobile data) when not in use.
- Minimize screen on time in auto-sleep settings.
- Avoid overusing the flashlight and features that require high and prolonged power. (video games, 4K video recording, etc.).
- Don't obsess about always charging the battery to 100%.The ideal is to do frequent partial loads.
- If you are traveling or will be away from a charger, Take an external battery (power bank) with you reliable and forget about running out of power.
Myths and realities about battery care
- It is not necessary to let the battery discharge completely every timeThis myth comes from nickel batteries, but lithium batteries work better with frequent partial charges.
- Charging your phone overnight isn't ideal, but modern devices typically cut off charging when they reach 100%. Still, microcycles can take their toll in the long run, so unplug when you can.
- The fast charges They're safe as long as your phone is compatible with them and you use the official charger. Otherwise, they can damage the battery.
- Miracle apps that promise to physically repair your battery They don't exist. They can only help calibrate or correct system errors, but actual wear and tear is irreversible.
- La periodic calibration It's not a bad idea if you notice errors in the percentage displayed, but it won't return the battery to its original capacity.
Quick Diagnostic: Why is your Android battery dropping so much?
If you experience a sudden battery drain, it's likely that one or more apps are running in the background (email, networking, messaging, etc.), the brightness is too high, a sensor is activated (e.g., GPS or Bluetooth), or the environment is very hot and the system is trying to cool down.
Monitoring apps allow you to discover in real time which processes or services are consuming the most energy and act accordingly: force-quit apps, disable unnecessary widgets, clear RAM, or even perform a reboot to return to a stable state.
Should I change the battery if its health is low?
If the battery health percentage estimated by apps like AccuBattery, Battery Guru, or Electron is very low, or you experience blackouts, drastic drops in performance, or overheating while charging, the most effective option is to have it replaced by an authorized service center. This isn't always a simple procedure for sealed phones, but it's the most reliable way to restore your smartphone's original performance and battery life.
Monitor and maintain your Android phone's battery Today, charging is easier and more effective than ever thanks to the tools and tips available. Staying informed about the actual battery status, acting on the data, and practicing good charging habits is key to getting the most out of your device and extending its lifespan.
