Android smartphones nowadays are available in a wide variety of sizes, styles, and form factors. There is a large market with many possibilities for foldable phones in addition to the traditional slab flagship smartphones and all-around mid-range smartphones.
However, battery life has always been a problem for all Android users, regardless of the device they use. The majority of Android users are concerned about how long their phone will last between charges. Many people adopt practices based more on misconceptions than facts in an effort to maintain battery health.
Although many old pieces of advise still exist, Android phones have become much more intelligent. Here are some typical fallacies about charging that people still hold onto, along with the actual facts.
Only the original charger for your phone brand should be used.
The majority of smartphone manufacturers have followed Apple’s example and ceased included a charger in the box since the release of the iPhone 12 in 2020. Additionally, they frequently encourage you to purchase their official charger, which is typically more expensive than alternatives found on Amazon or Best Buy. However, that isn’t the complete story.
For a quick and safe charge, you don’t have to use the same brand of charger. In addition to meeting all safety and charging requirements, certified third-party chargers from companies like Anker, Belkin, Spigen, and UGreen are less expensive than those offered by phone OEMs.
Additionally, the majority of these brands’ chargers support the majority of fast charging protocols, including USB-PD, PPS, and Quick Charge. It’s likely that a decent third-party charger will function perfectly unless your handset uses extremely specialized proprietary charging technology, like as Xiaomi’s HyperCharge or OnePlus’ SuperVOOC.
Wireless charging is incredibly effective and safe.
Wireless charging is now supported by the majority of Android flagship handsets, and although it’s a handy feature, it’s not necessarily the best option for battery health. Compared to wired charging, wireless charging produces more heat. Your battery may lose some of its original charge over time due to the accelerated degradation caused by excessive heat.
Therefore, try to avoid using wireless charging on a regular basis. Although it’s acceptable on occasion, if you would rather use a Qi-certified charger on a regular basis, take into account wireless chargers with integrated fans or temperature control, as these features aid in lowering heat production. Despite this, cable charging is still one of the greatest choices (and it’s typically faster, too).
Your phone’s battery will die if you leave it plugged in all night.
The idea that leaving cellphones plugged in overnight will “overcharge” the battery, damage it, and accelerate its depletion is one of the most widespread misconceptions regarding charging. However, that is untrue. These days, Android devices are intelligent enough to charge overnight without causing battery damage.
Nowadays, the majority of phones have intelligent battery optimizations that learn your usage and cut off charging when the battery reaches 80%. These optimizations are frequently AI-enabled. To reduce battery stress, the last 20% is charged right before you usually disconnect your phone.
However, charging to 100% on a regular basis is also not recommended. When left fully charged for extended periods of time, lithium-ion batteries—found in phones like the Google Pixel 9 Pro and Samsung Galaxy S25 Ultra—degrade more quickly. Setting a charge restriction, such as stopping at 80%, is a better long-term habit if your phone allows it.
It’s not good to charge your phone several times a day.
Another widespread misconception is that you should only charge your phone when battery reaches 0% and that charging it more than once a day is detrimental. However, that is untrue. Frequently charging lithium-ion batteries is not a problem for them. Actually, tapping 0% repeatedly may cause more damage than good to these cells.
For the optimum battery health, you should try to keep your phone within the 20% to 80% range, as this is where lithium-ion batteries are meant to operate. Charging your phone in short bursts throughout the day is less stressful on the battery than completely draining it to nothing.
Every phone is compatible with every fast charger.
Fast charging is supported by almost all Android devices nowadays, although it is unrealistic to expect all fast chargers to function in the same manner. The charger you’re using might not function as intended because the majority of Android OEMs utilize different fast charging protocols. There are numerous rapid charging protocols, such as USB-PD, PPS, and OnePlus’s proprietary SuperVOOC.
An incompatible fast charger won’t harm your phone’s port, but it probably won’t provide rapid charging. Using the correct charger will charge your phone as intended. You won’t receive the speed you’re hoping for if you don’t check your phone’s supported charging protocol before purchasing a new charger.
Did you knew all these?
Overall, we still hold onto several widespread myths about charging gadgets, many of which date back to the 2000s. However, cellphones have advanced significantly over time, and thanks to a number of clever features, they can now control charging more effectively.
Beyond being aware of these facts, you can really extend the battery life of your phone by incorporating a few simple tips into your daily routine.
