By 2024, battery degradation will impact even more devices as EVs go mainstream. That makes optimizing battery health more important than ever.
In this ultimate guide, we’ll explore the latest tips and techniques to extend battery lifespan. You’ll learn how to prolong battery life for all your devices. From changing settings to replacing aged batteries, we have the solutions to keep you powered up in 2024 and beyond.
Why Battery Health Matters Now More Than Ever
Battery capacity naturally fades over time due to chemical processes inside the cells. As lithium-ion batteries charge and discharge, lithium ions shuttle between the anode and cathode. This causes slow physical changes to the electrodes.
Repeated charge cycles spread out the anode material, lowering its ability to store lithium ions. Meanwhile, the cathode material starts to break down, reducing its capacity. This process, called capacitance loss, reduces a battery’s overall energy storage and lifespan.
Battery wear gets worse when devices heat up during operation or charging. High temperatures accelerate chemical reactions inside lithium-ion cells. This brings faster capacitance loss and battery aging.
Plus, totally draining or overcharging batteries also exacerbates electrode damage. That’s why device manufacturers recommend keeping batteries between 20-80% charge whenever possible. Staying in this sweet spot minimizes capacitance loss.
But even with moderate use, lithium-ion batteries still lose around 2% of their capacity per year. And the more you tax your device, the faster battery health declines. This means our power-hungry gadgets need some special care for longevity.
By 2024, longer-lasting batteries will be even more essential. As electric vehicles go mainstream, drivers will demand battery packs that last over 150,000 miles. And with smartphones now lasting up to 5 years, users want batteries that won’t die after just 500 charge cycles.
That’s why it’s crucial to know how to optimize battery health. With some planning and TLC, you can extend the usable lifespan of any lithium-ion battery.
Tips to Extend Smartphone Battery Lifespan
With heavy daily use, smartphones take some of the biggest battery abuse. Display brightness, gaming, and constant data streaming can all tax your phone’s battery. Without some adjustments, your phone’s battery health could plummet in just 2-3 years.
Here are 7 ways to improve battery lifespan on your smartphone:
1. Use Lower Screen Brightness
The display drains more battery power than any other smartphone feature. Using maximum brightness strains the battery, accelerating capacitance loss.
Instead, go with the lowest brightness comfortable for your surroundings. Enable auto-brightness so your phone optimizes the display for ambient light. You’ll also slash power consumption by choosing darker wallpapers.
2. Disable Unnecessary Features
Disable any phone features you don’t regularly use, like NFC or vibration. Turn off WiFi/Bluetooth when not in use. And don’t allow apps to run location services unless truly needed.
Restrict background data and push notifications for apps that over-sync. Limit processor-intensive activities like gaming. All these steps ease the load on your phone’s battery.
3. Avoid Heat Exposure
Don’t leave your phone in hot cars or direct sunlight. High ambient temperatures degrade batteries faster. Also, use phone cases that dissipate heat instead of trapping it. And avoid prolonged intensive activities that cause internal heat buildup.
4. Charge Smart
Keep charging levels between 20-80% whenever possible. Completely draining or overcharging the battery strains electrodes. Use slower chargers that are gentler on battery health. Unplug once fully charged to prevent trickle charging. And avoid charging batteries for prolonged periods when hot.
5. Update Software
Software updates often include battery health optimizations. Accept all major OS updates and patches as they become available. But resist the urge to join early beta programs, as unstable software can discharge batteries too quickly.
6. Replace Aging Batteries
About 500 complete charge cycles, your phone’s battery capacity will drop to 70-80%. At this point, it’s time to replace the battery to restore full-day endurance. Use OEM parts and have an experienced technician do the swap. Replacement restores battery lifespan to like-new.
7. Consider a Battery Case
For extra protection, use a battery case for your phone. Battery cases add extra capacity, keeping your phone’s battery topped up. This avoids straining the internal battery with frequent recharges. The case absorbs most of the charge cycling. So your phone’s battery stays healthier, lasting 2-3 years longer.
How to Extend Electric Vehicle Battery Life
Electric vehicles place huge demands on their lithium-ion battery packs. To ensure your EV’s battery lasts over 150,000 miles, follow these tips:
1. Charge to 90% Max
Never fully charge an electric vehicle battery if possible. Charging to 100% strains battery cells and increases electrode corrosion. Instead, set charge limits to 90% or below when using public fast chargers. Slow overnight charges at home can go to 100%, but avoid that habit on the road.
2. Charge at Moderate Temps
An EV battery charges fastest when hot, but excessive heat also shortens battery life. Only use DC fast charging in temperate weather between 45-90° F. In very hot or cold weather, skip fast charging to protect the battery.
3. Limit DC Fast Charging
While fast charging is convenient, it exerts significant stress on EV batteries. Use it sparingly and rely on slower Level 2 charging when possible. Also limit deep battery discharges, keeping the state of charge above 20% to minimize electrode damage.
4. Actively Cool/Heat Battery Pack
Modern EVs actively manage battery temperature while charging and driving. Avoid overriding default cooling/heating settings unless absolutely necessary. Maintaining optimal battery temp will maximize the pack’s lifespan.
5. Update Vehicle Software
EV automakers continuously improve battery management software. Accept all OTA updates so your EV stays optimized. Updates fine-tune charge rates and temperatures based on the latest research. Keeping firmware updated gives your EV battery the best possible care.
6. Don’t Store at Full/Empty States
When parking your EV, aim for a 40-50% battery state of charge if parking over 2 weeks. Storing EVs at high or low charge levels strains the battery. If possible, also avoid parking for prolonged periods in very hot or cold environments.
7. Replace Cells as Needed
EV batteries may need single cell replacements over their lifespan. Diagnostics can identify weak battery cells. Swapping out a few degraded cells early on helps restore range and protect the overall battery pack.
Optimizing Battery Health for Laptops & Tablets
Like smartphones, laptops and tablets need some special care to prolong battery lifespan:
1. Manually Adjust Display Brightness
Use auto-brightness selectively and override when possible. Manuel brightness gives you finer control over display power consumption. Dim the screen further when on battery versus wall power.
2. Moderate Power Modes
Use mid-level power modes that reduce performance and screen brightness without completely crippling your device. Aggressive power savings modes discharge batteries too rapidly, causing undue stress.
3. Remove Battery for Prolonged Storage
If storing your laptop or tablet over 2-3 months, discharge the battery around 50% then remove it from the device. Storing at high and low charge levels degrades batteries over time.
4. Limit Charge Cycles
Avoid charging your device every day from empty. Instead, top up periodically before reaching low charge levels. This avoids performing a full charge cycle so frequently, reducing long-term battery wear.
5. Replace Swollen Batteries ASAP
If the battery case bulges or swells, that indicates physical damage and potential hazard. Promptly stop using the device and have the battery replaced. Using damaged batteries risks serious failures.
6. Keep Batteries Cool
Avoid prolonged intensive laptop use on beds/sofas, which can block cooling vents. Use hard, flat surfaces to keep airflow intact. Also avoid leaving devices in hot environments like cars.
7. Optimize Software Settings
Check for battery optimizations like reduced background app activity and suspended processes when minimizing windows. Enable power-saving GPU and processor settings for less demanding tasks. Keep your OS and firmware updated for continual improvements.
DIY Battery Health Optimization
Beyond device settings and usage habits, there are a few DIY tweaks to further improve battery lifespan:
Refresh Lithium-Ion Batteries
Every few months, manually run a battery through 2-3 full discharge/charge cycles. This helps re-calibrate voltage sensors and keeps charge capacity optimized. Just don’t overdo it – deep cycling daily hastens degradation.
Avoid Third-Party Chargers
For maximum battery health, use the included OEM charger and cable. Third-party options often charge at higher uncontrolled voltages that strain battery cells. Stick to certified accessories that comply with the manufacturer’s voltage specs.
Replace Weak Cells
In devices with individual replaceable cells, swap out any underperforming batteries showing substantially lower voltages. Weak cells drag down capacity and strain the overall battery pack.
Add Supplemental Battery Packs
For devices that support external battery packs, use them to share the load. The supplemental pack absorbs most charge cycles, reducing wear on the internal battery. Just make sure to follow usage and charging guidelines for the external pack as well.
Use Optimized Charging Stations
Some third-party charging stations optimize voltage and charge levels for battery longevity. Look for “battery-friendly” certification to identify products that follow manufacturer guidelines. Avoid no-name chargers.

DIY Battery Recovery
In a pinch, you can attempt to repair and restore worn batteries yourself. Carefully discharging fully charged cells to zero volts and then recharging sometimes helps regain lost capacity. But this process strains batteries, so use it sparingly.
When to Replace Batteries
No battery lasts forever. With moderate daily use, expect lithium-ion batteries to lose 20% capacity after 2-3 years. At this point, it’s time to replace batteries in smartphones, tablets, and laptops.
More demanding use shortens usable battery lifespan. Capacity declining below 70% indicates replacement time for heavy duty devices. And EV batteries may need replacement after 8-10 years or 150,000+ miles.
Watch for other signs of battery failure:
- Minimal runtime even when fully charged
- Frequent unexpected shutdowns
- Failure to hold a charge
- Strange odors or leaks
- Case damage like swelling
Replacing worn lithium-ion batteries restores charge capacity and performance. When possible, opt for OEM batteries that exactly match your device’s specs. And have an experienced technician do the installation to avoid damage.
The Future of Battery Longevity
While lithium-ion batteries dominate today, emerging technologies promise even longer lifespan. Lithium titanate, lithium sulfur, and solid state batteries can endure thousands more charge cycles.
Advanced electrolytes will reduce internal resistance and electrode degradation. New nanostructured materials like graphene will minimize capacitance loss. And improved precision charging algorithms will optimize voltage and current for battery health.
But for now, a bit of care will go a long way to extending the life of your current devices. With the right usage habits and preventative maintenance, your lithium-ion batteries can stay healthy and functional for years to come.
