For instance, a battery that has a 5000mAh unit rating is capable of powering a smartphone drawing 100 mA for 50 hours.

from time to time (say 15–20 minutes at a time). So, in such situations, your phone’s battery should last 8–9 hours. A 4000 mAh battery, on a full charge, will last for 4000 hours when the circuit it powers draws 1 mA current. The same battery on a full charge, will last 4 hours if 1000 mA (1 A) is being drawn.

A 4000mAh battery life can last up to 4,000 hours, depending on the current required by the object being powered (measured in mA).

Smartphones with 5000mAh battery With a 5000mAh battery, the smartphone will almost never run out in a day, no matter how you use it. It’s especially useful for creators and bloggers who would need to use the camera more often than not shooting videos in high-resolution.

1. Capacity loss: the faster the charging speed, the greater the capacity loss. According to the preliminary estimate, the capacity loss of the 100W fast charge battery is about 20% more than that of the 30W PD fast charge, that is, the 5000mAh is turned into 4000mAh.

If you are not using a screen guard, you will have to be extra careful with the bulky phones. One of my test phones with a 6000 mAH battery fell from a small height, and the display broke. Most other phones would have survived that fall, but because of the extra weight, the display shattered.

A 6000 mAH battery can theoretically provide 1000mA for 6 hours, 6000mA for 1 hour, 100mA for 60 hours, and 10mA for 600 hours.

A: Yes, the mAh rating will give you longer run times between recharges. The higher rated mAh of a battery has no effect on electronic devices other than they allow longer term use.

In general, the higher the mAh, the longer the battery will last. If your battery is rechargeable then the mAh rating is how long the battery will last per charge. The bigger the battery’s gas tank (mAh rating) the longer the flashlight will run.

Originally Answered: Can you replace battery with higher mah? Yes you can, however, the voltage must be the same (+/- 5%). Also note that some battery manufacturers lie about the rated mAh.

You can replace your battery with a slightly different mAh capacity, as long as it is the same voltage; we would recommend choosing your replacement batteries with the nearest possible mAh rating. It is not recommended to replace your batteries with a much higher mAh capacity.

the 600 mah battery is effectively half again as powerful as the 400 mah battery. So the answer is the 600mah will work if the battery has the same battery number (which equates to same voltage, battery physical size, and plug type) and will provide more talk time than your old 400mah battery.

In short, using batteries with extra energy capacity will not harm your device, but would, instead, power the device for a longer time (all other considerations unchanged).

Originally Answered: Can I replace a 2400 mAh battery with 3000 mAh? Most of the times, yes you can, if it physically fits and has the same voltage. Itwill last longer and take longer to recharge.

Excessive overcharging of a NiMH cell can result in permanent loss in capacity and cycle life. If a cell is overcharged to the point at which pressure begins to build up, elevated temperatures are experienced and can cause the separator to lose electrolyte.

If it runs slow for a long time then it could be bad. Try charging slow for a few time to see if the pack conditions. The only way to test them is to use them and then watch very carefully for temperature differences between cells after charge and discharge.

One is yes, you can. Second is No. But both of them based on the voltage and current rating provided by manufacturer of the battery and not by mAh.

Below mentioned are some signals you can look for:

1. Battery drains quickly.
2. The phone does not charge despite being plugged into a charger.
3. The phone does not hold the charger.
4. Phone reboots on its own.
5. The battery bumps up.
6. Battery overheats.

Signs Your Smartphone Battery Needs to be Replaced

1. You’re Constantly Dying.
2. The Phone is Getting Older.
3. Charging Cycles Don’t Fully Recharge the Phone.
4. The Battery Runs Hot.
5. Get it Replaced.
