How long should a smartphone or tablet work on battery power
Battery life depends on several factors, not just capacity. The working time is affected by:
It seems that everything is simple: you use the device a lot. the battery discharges faster. But the operating time also depends on the load.
If the load is large: mobile Internet, movies, games with good graphics. the device discharges in a few (2‒5) hours.
If the load is small: music, books, SMS, conversations. the device lasts longer (5‒20 hours).
The more applications installed on the device, the faster the battery runs down. Quality also strongly affects: poorly made applications constantly load the processor and prevent the device from falling asleep.
Over time, errors appear in the operating system. The reasons are different: they incorrectly updated the firmware, installed poor-quality applications and deleted them incorrectly, did not clear the memory of old files, etc. The more errors, the faster the battery runs down.
The useful battery capacity decreases with time. The older the battery, the less charge it can carry.
The worse the network signal, the faster the battery will drain. This is due to the fact that the transmitter of the device is forced to work at higher power in order to maintain a connection to the network.
To answer the question: “My smartphone discharges in so many hours, is this normal?”. it is impossible. To do this, you need to collect a lot of information.
In the average mode. a couple of hours of music, a couple of hours of Internet, 40 minutes of calls, instant messengers or mail. the device should work for about one to two days. But remember that everything is individual.
What to do if the battery runs out quickly
If you suspect that something is wrong with the device, and the battery runs out much faster than it should, try the following tips:
The more applications installed on the device, the faster the battery runs down. Some applications influence so much that the battery runs out in a few hours.
To find out whether or not applications are the case, boot the device in safe mode. In safe mode, all downloaded applications do not work. those that are installed after purchase. Only system applications work. those that are installed at the factory.
See how long a smartphone or tablet will work on a single charge in safe mode, and draw conclusions.
If the battery starts to discharge more slowly, then the problem is in some applications that were installed after purchase. Uninstall applications that you installed or updated recently, and monitor the device until the battery runs out more slowly.
If the battery runs at the same speed in safe mode, try other tips.

If you are not using any system applications, disable them. Applications “freeze”, and will not work until they are turned on.
If you use a smartphone or tablet a lot and you don’t have a standard battery, buy an external battery.
The external battery works as a portable outlet:
Such batteries are available in different sizes and capacities, they have a reasonable price, and they are universal. they charge everything that is charged from USB.
Usually the screen works at full brightness, and this consumes a decent battery charge. To spend less, use the automatic brightness control (if any). A special sensor analyzes the conditions in which the device operates and automatically sets the brightness level.
If the device does not have automatic adjustment, reduce the brightness manually to a comfortable level.
If your smartphone has two SIM cards, and you do not use one of them, pull it out. The smartphone is wasting energy to maintain a connection to the cellular network, and the battery runs out faster. Do not leave SIM cards on your smartphone that do not have a network in the area where you are located (for example, travel SIM cards).
If you do not use Wi-Fi, Bluetooth, GPS, NFC, or mobile Internet. turn them off, they consume a lot of energy.
For this, the easiest way is to use the quick settings panel. To open it, swipe the screen from top to bottom.
The worse the network signal, the faster the device will discharge. This is due to the fact that the transmitter of the device is forced to work at higher power in order to maintain a connection to the network.
If you are often in places where there is poor mobile network coverage or it is completely absent, use the “Airplane” or “Offline” mode.
In this mode, the mobile network is turned off, and the device does not spend energy to search for it. This advice is especially relevant for tablets, as a SIM card is used less often in them than in a smartphone.
Some accounts may synchronize data from the device’s memory, i.e. make a copy of them and send them to your account.
Imagine that you created a new contact on your smartphone. If it has a Google account and synchronization is enabled, the smartphone will immediately copy this contact to your account. If you enter this account on another device, the contact will automatically be downloaded to your notebook.
Synchronization is a convenient function, but it prevents the device from falling asleep, because it constantly checks to see if new data has appeared. To reduce battery consumption with this function, set up synchronization. select which data should be synchronized automatically and which data manually.
