How long does 4800mah last

In general, the more mAh and the longer the battery capacity or battery life. A higher number means that the battery can store more energy, so it has a higher capacity. Of course, this also means longer battery life for a given usage. The batteries with higher amp hours deliver more power and more performance, allowing the battery to work for a longer time on a full charge as compared to the cells with lower amp hours.

As the AH or amp-hours rating of the battery indicates the consumers about the amperage that a battery will provide in one hour. If it is a featured phone, so it will take 4—5 days because there is no background process as smartphones.

If it is a smartphone, it will normally take 6—7 hours normal , 2—3 hours rough usages means using internet,listening to music etc. 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. An mAh battery will supply mA for the same time before it needs a recharge.

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.

The Google Pixel 4 and its Soli radar system is a prime example of a feature that drains much more battery than a handset without it.

Including a time-of-flight camera focusing system, more powerful stereo speakers, or a 4K display all impact battery life. Even something seemingly as small as charging up the S Pen on recent Galaxy Note phones adds up. These features make handsets unique, but they come with a price. The trend in faster refresh rate displays plays a big part in why modern phones consume so much power.

This appears to be why the Samsung Galaxy S20 series phones stick to 60Hz out of the box, despite technically supporting Hz. Want more examples? The two phones have otherwise virtually identical specs, highlighting just how much of an effect displays and refresh rates have on battery life. Smartphone software can also affect battery life by killing off background apps to reduce CPU usage and wake-ups.

Another recent trend complicating the matter of mAh vs battery life is the launch of 5G. Complicating things further, different 5G modems and chipsets drain different levels of power.

The move to 5G hardware has undoubtedly increased the necessity for larger battery capacities. Again though, this all depends on other hardware. Manufacturers have to weigh up cost, space, and the hardware they intend to power.

The more feature-rich a handset, the tricker the balancing act. Mid-range smartphones with less energy-hungry technology, such as the Pixel 3a, tend to get away with smaller batteries while still providing all-day battery life. I have a black pack here that I just tried both of these methods which the second method worked on. The charge indicator on the front of the plug glows red as the battery pack charges.

When the light glows green, the battery pack is fully charged. Notes: Fully charging the battery can take up to 7 hours using the play and charge cable. Insert your rechargeable battery pack into your wireless Xbox controller. The wireless battery pack will recharge while your Xbox is turned on and connected via Play and Charge cable to the controller. The battery is fully charged when the light on the charger turns from red to green. 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. This method detects a drop in voltage that appears as the cell becomes full charged. However when charging an NiMH cell it is found that only a small drop in voltage is seen. An NiMH charger must be able to detect a voltage drop of around 5mV per cell. Check the reading. A fully charged battery will typically display a voltmeter reading of about If your voltmeter is showing a voltage anywhere between Any voltage above If your battery dies, you can simply just switch them.
