Generally, Android phones are known for long-lasting battery capacity irrespective of how many processes you are running at the same time, the battery life shouldn’t be an issue. But it could be really confusing when you discover your android phone is not charging when connected to your charger and some times your battery percentage to remain at the same level for hours or in fact drop steadily.
The problem occurs in various ways, either your phone won’t charge when it is plugged in, or it only charges very slowly (sometimes barely faster than it is discharging). It’s a very common complaint, and I recently encountered this issue with my Phantom Z
Am very certain you must have thought of “Why is my Android phone not charging or discharging despite being connected to a power source?”
Lets see the obvious reasons below:
Insufficient power source: If you’re charging using a PC (via USB cord) or from a faulty power source then this is possible.
Bad USB port: A loose, cracked or broken phone USB port could be a cause.
Bad charger: If the charger is faulty or not powerful enough then you can expect something like this
ROM Issues: If you flashed a custom ROM / Firmware upgrade with power efficiency bugs then you have another possible reason.
Heavy Usage During Charging: If you’re running processor / battery intensive processes during charging then you have another possible cause
Bad battery: Some batteries have problems retaining charge after extensive use.
Some of you may have suffered from a phone that won’t charge properly and probably rushed out to buy a new charger to fix it, well, you are wrong. What if the issue isn’t the charger? and the actual issue is your phone battery.
